                               PROSPECTUS SUMMARY
  This Prospectus contains certain statements of a forward-looking nature
relating to future events or the future financial performance of the Company.
Prospective investors are cautioned that such statements are only predictions
and that actual events or results may differ materially. In evaluating such
statements, prospective investors should specifically consider the various
factors identified in this Prospectus, including the matters set forth under
the caption "Risk Factors," which would cause actual results to differ
materially from those indicated by such forward-looking statements. The
following summary is qualified in its entirety by the more detailed information
and financial statements, including notes thereto, appearing elsewhere in this
Prospectus.
 
                                  THE COMPANY
  Interlink Computer Sciences, Inc. ("Interlink" or the "Company") is a leading
supplier of high-performance solutions for enterprise networked systems
management. Interlink provides software and services which enable customers
implementing client/server systems to use their IBM and IBM-compatible MVS
mainframes as "enterprise servers" in distributed, heterogeneous client/server
network environments. The Company's products and services enable customers to
transport, access and manage mission-critical data and applications across
distributed network environments. The Company develops and markets the
TCPaccess products which provide for enterprise server TCP/IP connectivity,
fault tolerance and CICS-to-LAN application integration. Interlink also
develops and markets the HARBOR products for network backup, archive and
restore, and for application, data and software distribution. The Company also
supplies network printing and other applications which expand the functionality
of the enterprise server.
 
  Many large organizations depend on centralized mainframe computer systems to
manage mission-critical software applications and to serve as the repository
for essential business data. Recently, advances in hardware, software, and
networking technologies have led to the deployment of client/server systems, in
which computing tasks are distributed throughout a network of computers.
Organizations are now integrating mainframe computers into client/server
networks as "enterprise servers" which, like other servers on the client/server
network, have a specialized purpose and function. Specifically, the enterprise
server and the systems management applications associated with its use have
proven capable of providing reliable and efficient systems management, data
security, and distribution of data and applications. Improvements in the cost-
effectiveness of mainframe systems have significantly increased the use of
mainframe computers as enterprise servers.
 
  With almost ten years of experience in the networked systems management
industry, Interlink provides networking solutions that build upon its expertise
in the integration of the MVS operating system with TCP/IP and its reputation
for high-performance, efficient products. Interlink's objective is to enhance
its position as a leading supplier of high-performance solutions for enterprise
networked systems management. Key elements of the Company's strategy include:
supplying a suite of products that expand the functionality of the enterprise
server; leveraging the combined existing customer bases of TCPaccess and HARBOR
and capitalizing on new sales opportunities; employing a consultative sales
approach to build long-term customer relationships; differentiating its
networking solutions through superior customer support; and leveraging
strategic marketing and development relationships in order to provide complete
solutions to its customers' evolving network systems management needs.
 
  As of March 31, 1996, the Company had licensed its TCPaccess and HARBOR
products to approximately 900 and 160 customer sites worldwide, respectively.
The Company markets and sells its software and services primarily through its
direct sales organization and, to a lesser extent, through resellers and
international distributors. The Company's major customers include, among

                                 RISK FACTORS
 
  This Prospectus contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain
factors, including those set forth in the following risk factors and elsewhere
in this Prospectus. The following factors should be carefully considered in
evaluating the Company and its business before purchasing the Common Stock
offered hereby.
 
COMPETITION
 
  General. The market in which the Company operates is intensely competitive
and is characterized by extreme price competition and rapid technological
change. The competitive factors influencing the markets for the Company's
products include product performance, price, reliability, features,
scalability, interoperability across multiple platforms, adherence to industry
standards, and the provision of support and maintenance services. The Company
competes with a number of companies, principally International Business
Machines Corp. ("IBM"), that specialize in one or more of the Company's
product lines, and such competitors may have greater financial, technical,
sales and marketing resources to devote to the development, promotion and sale
of their products, and may have longer operating histories, greater name
recognition, and greater market acceptance for their products and services
compared to those of the Company. There can be no assurance that the Company's
current competitors or any new market entrants will not develop networked
systems management products or other technologies that offer significant
performance, price or other advantages over the Company's technologies, the
occurrence of which would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
  Network Transport Products. The Company sells its TCPaccess suite of
products principally to customers who have installed IBM mainframes using the
MVS operating system. The Company's main competition for its TCPaccess
products is IBM. IBM sells TCP/IP and associated products for its MVS
mainframe systems that compete directly with the Company's TCPaccess product
line. In addition, IBM recently released its OS/390 operating system, which
includes TCP/IP communications software in a bundle of software provided to
purchasers of OS/390. An IBM customer can request to have the IBM TCP/IP
product removed from the software bundle provided by IBM and thereby reduce
the purchase price of the system purchased. The reduction in the purchase
price related to the exclusion of IBM's TCP/IP for MVS product from its
software bundle, in certain model groups, is substantially smaller than the
price the customer would have to pay to purchase the Company's corresponding
TCPaccess product. Because in some IBM model groups IBM's TCP/IP product is
less expensive to purchase than the Company's corresponding TCPaccess products
in the same model groups, there could be substantial erosion of the Company's
margins if the Company reduces the price of its TCPaccess products in order to
compete against IBM, which erosion would have a material adverse effect on the
Company's business, financial condition and results of operations. Also, IBM
could in the future decide to include its TCP/IP product in the bundle of
software provided to purchasers of its OS/390 operating system without charge.
The Company believes that any reduction in price of the IBM TCP/IP products,
or the bundling of those products without charge in its OS/390 operating
system, would require the Company to either reduce the prices of its TCPaccess
products or substantially increase sales and marketing expenses, or both, in
order to continue to sell its TCPaccess products, which actions would have a
material adverse effect on the Company's business, financial condition and
results of operations. In addition, if IBM were to develop or design its
OS/390 operating system or other products so that its TCP/IP product cannot be
removed, customers who otherwise would have been inclined to purchase the
Company's TCPaccess product may not do so, which would have a material adverse
effect on the Company's business, financial condition and results of
operations. In addition, the Company derives a substantial portion of its
revenues from maintenance agreements with its TCPaccess customers. If the
Company sells fewer TCPaccess products, either due to competition from IBM or
otherwise, the Company's maintenance revenues would be reduced, which would
have a material adverse effect on the Company's business, financial condition
and results of operations. If IBM reduces the combined price of its TCP/IP
products and maintenance, IBM's combined price for its TCP/IP products and
maintenance would be more price competitive
 
                                       5
<PAGE>
 
with the Company's product line, and the Company's product and maintenance
revenues would be adversely affected. The Company also competes with IBM,
Apertus Technologies Inc. ("Apertus"), Cisco Systems, Inc., Computerm
Corporation ("Computerm"), Network Solutions, Inc. and Memorex Telex Corp.
("Memorex") in the network controller market, where the Company resells the
network controller of Bus-Tech Inc. ("Bus-Tech"), a division of Storage
Technology Corp. ("Storage Technology"), to provide the hardware connection
which links the enterprise server to the client/server network.
 
  System Management Applications. The primary competitors for the Company's
HARBOR Backup product are IBM, Storage Technology, Innovation Data Processing,
Inc. and Boole & Babbage, Inc. The Company's competition for the HARBOR
Distribution Manager are IBM, Novadigm, Inc. and Tangram Enterprise Solutions,
Inc. IBM is aggressively marketing its ADSM backup product, which is included
in the System View package on IBM's UNIX system, AIX. There can be no
assurance that IBM will not include the ADSM backup products in a software
"bundle" with the sale of its mainframe hardware systems. The bundling of
competing software products with mainframe hardware systems could have a
material adverse effect on the Company's business, financial condition and
results of operations. The Company also competes with software vendors who
develop and market products for UNIX and Windows NT operating systems, such as
Microsoft Corporation ("Microsoft"), Arcada Software, Inc., Cheyenne Software,
Inc., Computer Associates International, Inc., EMC Corporation, Hewlett-
Packard Company, Legato Systems, Inc. ("Legato"), Novadigm, Inc., OpenVision
Technology, Inc., PLATINUM technology, inc., Sterling Software, Inc., Sun
Microsystems, Inc. and Unison Software, Inc., which are focusing on enterprise
systems management applications. Although the Company recently signed a
strategic marketing agreement with Legato, the Company is still a competitor
of Legato in the storage management market. The Company also expects increased
competition from vendors of TCP/IP-to-SNA gateway products, including such
companies as Microsoft, Novell, Inc., Apertus and CNT/Brixton Systems, Inc.
Competition from these companies could increase due to an expansion of their
product lines or a change in their approach to enterprise systems management
or networking products. The bundling of network transport software with a
network controller by these competitors could prevent the Company from selling
TCPaccess to the customers of these competitors, which would have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
  Other Factors. The Company's ability to compete successfully depends on many
factors, including the Company's success in developing new products that
implement new technologies, performance, price, product quality, reliability,
success of competitors' products, general economic conditions, and protection
of Interlink products by effective utilization of intellectual property laws.
In particular, competitive pressures from existing or new competitors who
offer lower prices or other incentives or introduce new products could result
in price reductions which would adversely affect the Company's profitability.
There can be no assurance that the Company's current or other new competitors
will not develop enhancements to, or future generations of, competitive
products that offer superior price or performance features, that the Company
will be able to compete successfully in the future, or that the Company will
not be required to incur substantial additional investment costs in connection
with its engineering, research, development, marketing and customer service
efforts in order to meet any competitive threat. The Company expects
competition to intensify, and increased competitive pressure could cause the
Company to lower prices for its products, or result in reduced profit margins
or loss of market share, any of which could have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Business--Competition."
 
RELIANCE ON IBM AND EMERGENCE OF MAINFRAME AS ENTERPRISE SERVER
 
  The Company's current software products are designed for use with IBM and
IBM-compatible mainframe computers. Specifically, these software products
target users of the MVS operating system, the Customer Information Control
System ("CICS") communications subsystem and the IMS and DB2 database
management systems. As a result, future sales of the Company's existing
products and associated recurring maintenance revenues are dependent upon
continued use of mainframes and their related systems software. In addition,
because the Company's products operate in conjunction with IBM systems
software, changes to IBM systems
 
                                       6
<PAGE>
 
software may require the Company to adapt its products to these changes, and
any inability to do so, or delays in doing so, may adversely affect the
Company's business, financial condition and results of operations. Currently,
TCP/IP is the communications protocol for the Internet and is being adopted by
some organizations as the communications protocol for their client/server
local area networks ("LANs") and wide area networks ("WANs"). This adoption
has allowed IBM MVS mainframe computers to act as enterprise servers on such
networks. The use of mainframes as enterprise servers is relatively new and
still emerging. The Company's future financial performance will depend in
large part on the acceptance and growth in the market for centralized network
management. Adoption of another communications protocol on client/server
networks could make TCP/IP communication not viable, which would undermine the
demand for the Company's TCPaccess products, and have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Business--Sales, Marketing and Customer Support."
 
NEW PRODUCTS AND RAPID TECHNOLOGICAL CHANGE
 
  The markets for the Company's network transport products and systems
management applications are characterized by rapidly changing technologies,
evolving industry standards, frequent new product introductions and rapid
changes in customer requirements. The Company believes that its future success
will depend upon its ability to develop, manufacture and market products which
meet changing user needs, to continue to enhance its products and to develop
and introduce in a timely manner new products that take advantage of
technological advances, keep pace with emerging industry standards, and
address the increasingly sophisticated needs of its customers. There can be no
assurance whether TCP/IP will continue to be accepted as a communications
protocol on client/server networks. Furthermore, there can be no assurance
that the Company will be successful in developing and marketing, on a timely
basis, product enhancements or new products that respond to technological
change or evolving industry standards, that the Company will not experience
difficulties that could delay or prevent the successful development,
introduction and sale of these products, or that any such new products or
product enhancements will adequately meet the requirements of the marketplace
and achieve market acceptance. The Company's failure or inability to adapt its
products to technological changes or to develop new products successfully
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
  The introduction or announcement of products by the Company or one or more
of its competitors, including but not limited to IBM, embodying new
technologies, or changes in customer requirements or the emergence of new
industry standards and practices could render the Company's existing products
obsolete and unmarketable. As markets for the Company's products develop and
competition increases, the Company anticipates that product life cycles will
shorten and average selling prices will decline. In particular, average
selling prices and gross margins for each of the Company's products are
expected to decline as each product matures. There can be no assurance that
the introduction or announcement of new product offerings by the Company or
one or more of its competitors will not cause customers to defer purchasing
the existing products of the Company or that the Company will successfully
manage the transition from older products to new or enhanced products in order
to minimize disruption in customer ordering. Such deferment of purchases or
inability to manage the transition of products could have a material adverse
effect on the Company's business, financial condition and results of
operations. In addition, there can be no assurance that the Company will
successfully identify new product opportunities, develop and bring to market
in a timely manner such new products, or that products or technologies
developed by others will not render the Company's products or technologies
noncompetitive or obsolete. See "Business--Product Development."
 
  To date, the Company's core technologies for its principal network transport
products and systems management applications have been acquired and have not
been developed internally. There can be no assurance that the Company will
have the opportunity to successfully acquire or develop new technologies in
the future or that such technology, if acquired, can be successfully
integrated and commercialized by the Company. An inability to acquire, develop
or commercialize new technologies would have a material adverse affect on the
Company's business, financial condition and results of operations.

FLUCTUATIONS IN OPERATING RESULTS; ABSENCE OF BACKLOG; SEASONALITY
 
  The Company's operating results have historically been, and will continue to
be, subject to quarterly and annual fluctuations due to a variety of factors,
including: timely introduction, enhancement and market acceptance of new
versions of the Company's products; seasonal customer demand; timing of
significant orders; changes in the pricing policies by the Company or its
competitors; anticipated and unanticipated decreases in unit average selling
prices of the Company's products; increased competition; changes in the mix of
the products sold and in the mix of sales by distribution channel; the gain or
loss of significant customers; the introduction of new products or product
enhancements by competitors; currency fluctuations; and the failure to
anticipate changing customer product requirements. The Company typically sells
its products through a trial process to allow customers to evaluate the
effectiveness of the Company's products before determining whether to proceed
with broader deployment of such products. The Company's sales cycle, from the
date the sales agent first contacts a prospective customer to the date a
customer ultimately purchases the Company's product, is typically three to six
months for the TCPaccess products and six to nine months for the HARBOR
products. There can be no assurance however that the customers will purchase
the Company's products after such trial period or that the Company's sales
cycle will not lengthen, exposing it to the possibility of shortfalls in
quarterly revenues, which could have a material adverse effect on the
Company's business, financial condition or results of operations and cause
results to vary from period to period. The Company's operating results will
also be affected by general economic and other conditions affecting the timing
of customer orders and capital spending, and order cancellations or
rescheduling. Furthermore, it is possible that the Company's products may be
found to be defective after the Company has already shipped in volume such
products. There can be no assurance that defects in the Company's products or
failures in the Company's product quality, performance and reliability, will
not occur and such defects or failures will not have a material adverse effect
on the Company's business, financial condition and results of operations. If
such defects or failures occur, the Company could experience a decline in
revenue, increased costs (including warranty expense and costs associated with
customer support), delays in or cancellations or reschedulings of orders or
shipments, and increased product returns, any of which would have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
  The Company operates with very little backlog and most of its product
revenues in each quarter result from orders closed in that quarter, and a
substantial majority of those orders are completed at the end of that quarter.
The Company establishes its expenditure levels for sales, marketing, product
development and other operating expenses based in large part on its
expectations as to future revenues, and revenue levels below expectations
could cause expenses to be disproportionately high. If revenues fall below
expectations in a particular quarter, operating results and net income are
likely to be materially adversely affected. Any inability of the Company to
adjust spending to compensate for failure to meet sales forecasts or to
collect accounts receivable, or any unexpected increase in product returns or
other costs, could magnify the adverse impact of such events on the Company's
operating results.
 
  The Company's business has experienced and is expected to continue to
experience significant seasonality. The Company has higher sales of its
software products in the quarters ending in December and June and weaker sales
in the quarters ending in September and March. The decrease in product
revenues in the quarters ending in September is due to the international
customer seasonal buying patterns. The quarters ending in March are
historically weak due to government and large organization annual budgeting
cycles. Due to the foregoing factors, quarterly revenue and operating results
are likely to vary significantly in the future and period-to-period
comparisons of its results of operations are not necessarily meaningful and
should not be relied upon as indications of future performance. Further, it is
likely that in some future quarters the Company's revenue or operating results
will be below the expectations of public market analysts and investors. In
such event, the price of the Company's Common Stock would likely be materially
adversely affected. See "Selected Consolidated Financial Data" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

INTEGRATION OF ACQUISITION; HISTORY OF ACQUIRED TECHNOLOGIES
 
  The Company has no significant history of operations on a combined basis
with New Era, the developer of the HARBOR products, which the Company acquired
in December 1995 in a purchase transaction. Accordingly, the historical
financial statements and pro forma financial information presented in this
Prospectus may not be indicative of the results that would have been obtained
had the acquisition occurred prior to the commencement of the periods covered
therein. There can be no assurance that the Company will be successful in
integrating the operations and personnel of New Era into its business,
incorporating the HARBOR products and any other acquired technologies into its
product lines, establishing and maintaining uniform standards, controls,
procedures and policies, avoiding the impairment of relationships with
employees and customers as a result of changes in management, or overcoming
other problems that may be encountered in connection with the integration of
New Era. See "Selected Consolidated Financial Data," "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and Unaudited
Pro Forma Combined Condensed Consolidated Financial Statements and Notes
thereto.
 
  To date, the Company's core technologies for its principal network transport
products and systems management applications have been acquired and have not
been developed internally. There can be no assurance that the Company will
have the opportunity to successfully acquire or develop new technologies in
the future or that such technology, if acquired, can be successfully
integrated and commercialized by the Company. An inability to acquire, develop
or commercialize new technologies would have a material adverse effect on the
Company's business, financial condition and results of operations. The Company
may also seek to acquire or invest in businesses, products or technologies
that expand, complement or otherwise relate to the Company's current business
or product line. There can be no assurance that such acquisitions will be
successfully or cost-effectively integrated into the Company's current
operations, or that the acquired technologies will provide the necessary
complement to the Company's current products. If the Company consummates
additional acquisitions in the future that must be accounted for under the
purchase method of accounting, such acquisitions would likely increase the
Company's amortization expenses. In addition, any such acquisitions would be
subject to the risks of integration mentioned above. The Company does not
currently have any understandings, commitments or agreements with respect to
any potential acquisition or corporate partnering arrangements, nor is it
currently engaged in any discussions or negotiations with respect to any such
transaction.
 
RELIANCE ON AND RISKS ASSOCIATED WITH INTERNATIONAL SALES
 
  During the fiscal year ended June 30, 1995 and the nine months ended March
31, 1996, 42% and 43%, respectively, of the Company's total revenues were
derived from sales to international customers. The Company's international
sales have been primarily to European markets, and sales are generally
denominated in local currencies. In addition, sales in Europe and certain
other parts of the world typically are adversely affected in the third quarter
of each calendar year as many customers reduce their business activities
during the summer months. The Company expects that international revenue will
continue to represent a significant portion of its total revenue. The Company
intends to enter into additional international markets and to continue to
expand its operations outside of North America by expanding its direct sales
force, adding distributors and pursuing additional strategic relationships
which will require significant management attention and expenditure of
significant financial resources. To the extent that the Company is unable to
make additional international sales in a timely manner, the Company's growth,
if any, in international revenues will be limited, and the Company's business,
financial condition and results of operations would be materially adversely
affected. Sales to international customers are subject to additional risks
including longer receivables collection periods, greater difficulty in
accounts receivable collection, failure of distributors to report sales of the
Company's products, political and economic instability, nationalization, trade
restrictions, the impact of possible recessionary environments in economies
outside the United States, reduced protection for intellectual property rights
in some countries, currency fluctuations and tariff regulations and
requirements for export licenses. There can be no assurance that foreign
intellectual property laws will adequately protect the Company's intellectual
property rights. In addition, effective copyright and trade secret protection
may be unavailable or limited in certain foreign countries. Substantially all
of the Company's distribution and other agreements with international
distributors require any dispute between the Company and any distributor to be
settled by arbitration. Under these
 
                                       9
<PAGE>
 
agreements, the party bringing the action, suit or claim is required to
conduct the arbitration in the domicile of the defendant. The result is that,
if the Company has a cause of action against a party, it may not be feasible
for the Company to pursue such action, as arbitration in a foreign country
could prove to be excessively costly and have a less certain outcome depending
on the laws and customs in the foreign country. These international factors
could have a material adverse effect on future sales of the Company's products
to international end users and, consequently, the Company's business,
financial condition and results of operations.
 
  Most of the Company's international sales are denominated in local
currencies. In addition, at March 31, 1996 a majority of the Company's cash is
in international bank accounts. The Company has not historically attempted to
reduce the risk of currency fluctuations by hedging except in certain limited
circumstances where the Company has held an account receivable expected to be
outstanding for a period approximating at least 12 months. The Company may be
disadvantaged with respect to its competitors operating in a foreign country
by foreign currency exchange rate fluctuations that make the Company's
products more expensive relative to those of the local competitors. The
Company may attempt to reduce these risks by hedging in the future.
Accordingly, changes in the exchange rates of foreign currencies or exchange
controls may adversely affect the Company's results of operations. There can
be no assurance that the Company's current or any future currency exchange
strategy will be successful in avoiding exchange related losses or that any of
the factors listed above will not have a material adverse effect on the
Company's future international sales and, consequently, on the Company's
business, financial condition and results of operations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations," and
"Business--Sales, Marketing and Customer Support" and "--Customers."
 
DEPENDENCE ON DISTRIBUTORS AND STRATEGIC RELATIONSHIPS
 
  The Company's sales are primarily made through the Company's direct sales
force and the Company's distributors in international markets. In May 1996,
the Company entered into a strategic marketing agreement with Legato. The
Company has no historical relationship with Legato, and there can be no
assurance that the Company will be able to sell its products through Legato.
The Company is currently investing, and plans to continue to invest,
significant resources to develop additional relationships, which investments
could adversely affect the Company's operating margins. The Company believes
that its success in penetrating markets for its products depends in large part
on its ability to maintain these relationships, to cultivate additional
relationships and to cultivate alternative relationships if distribution
channels change. There can be no assurance that any distributor, systems
integrator or strategic partner will not discontinue its relationship with the
Company, form competing arrangements with the Company's competitors, or
dispute the Company's other strategic relationships. A former distributor of
the Company's TCPaccess products in Italy, Selesta Integrazioni SRL
("Selesta"), has threatened legal action over the recent termination of
Selesta as a distributor of the Company's TCPaccess products. Selesta
continues to distribute the Company's HARBOR products in Italy and Spain,
pursuant to its existing distributor relationship with New Era. See "--Legal
Dispute." The loss of, or a significant reduction in revenues from, the
Company's distributors through which the Company sells its products could have
a material adverse effect on the Company's business, financial condition and
results of operations. In addition, if one of the Company's distributors
declares bankruptcy, becomes insolvent, or is declared bankrupt before the
distributor remits to the Company the payments for the Company's products, the
Company may not be able to obtain the revenues to which it would be entitled
for sales made by such distributor prior to the bankruptcy or insolvency
proceeding. In addition, the Company's distributors generally offer other
products and these distributors may give higher priority to sales of such
other products.
 
DEPENDENCE UPON SUPPLIER
 
  Network access from the enterprise server to the network via the Company's
TCPaccess product requires a network controller, which the Company sells to
its customers. The Company's principal network controller, the 3762 Network
Controller, is supplied only by Bus-Tech and is resold by the Company. Sales
of network controllers have accounted for substantially all of the Company's
hardware revenues to date, and has accounted for 25% and 19% of product
revenues in the fiscal year ended June 30, 1995 and for the nine months ended
 
                                      10
<PAGE>
 
March 31, 1996, respectively. In addition, the Company also relies upon Bus-
Tech for network controller replacement parts. If the Company were unable to
purchase an adequate supply of such sole-sourced product on a timely basis,
the Company would be required to develop or locate alternative sources. If
such product became unavailable, the Company could be required to design a
comparable product, qualify an alternative source, or redesign its products
based upon different components. Furthermore, IBM could use its position as a
supplier of network controllers to gain a competitive advantage over the
Company. To date, the Company has not experienced any difficulty or
significant delay in obtaining any such sole-sourced product. However, there
can be no assurance that the Company will not face such difficulties or delay
in the future. An inability of the Company or its customers to obtain such
sole-sourced controllers could significantly delay shipment of products, which
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
DEPENDENCE UPON PROPRIETARY TECHNOLOGY; RISK OF THIRD PARTY CLAIMS OF
INFRINGEMENT
 
  The Company's success and ability to compete is dependent in part upon its
proprietary information. The Company relies primarily on a combination of
copyright and trademark laws, trade secrets, software security measures,
license agreements and nondisclosure agreements to protect its proprietary
technology and software products. There can be no assurance, however, that
such protection will be adequate to deter misappropriation, deter unauthorized
third parties from copying aspects of, or otherwise obtaining and using, the
Company's software products and technology without authorization, or that the
rights secured thereby will provide competitive advantages to the Company. In
addition, the Company cannot be certain that others will not develop
substantially equivalent or superseding proprietary technology, or that
equivalent products will not be marketed in competition with the Company's
products, thereby substantially reducing the value of the Company's
proprietary rights. Furthermore, there can be no assurance that any
confidentiality agreements between the Company and its employees or any
license agreements with its customers will provide meaningful protection for
the Company's proprietary information in the event of any unauthorized use or
disclosure of such proprietary information.
 
  There can be no assurance that others will not independently develop similar
products or duplicate the Company's products. 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. There can be no assurance that the steps taken
by the Company to protect its proprietary technology will prevent
misappropriation of such technology, and such protections may not preclude
competitors from developing products with functionality or features similar to
or superior to the Company's products. A substantial amount of the Company's
sales are in international markets, and the laws of other countries may afford
the Company little or no effective protection of its intellectual property.
 
  While the Company believes that its products and trademarks do not infringe
upon the proprietary rights of third parties, there can be no assurance that
the Company will not receive future communications from third parties
asserting that the Company's products infringe, or may infringe, the
proprietary rights of third parties. The Company expects that software product
developers will be increasingly subject to infringement claims as the number
of products and competitors in the Company's industry segments grow 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 and diversion of technical and management personnel, cause product
shipment delays or require the Company to develop non-infringing technology or
enter into royalty or licensing agreements, any of which could have a material
adverse effect on the Company's business, financial condition and results of
operations. Such royalty or licensing agreements, if required, may not be
available on terms acceptable to the Company or at all. In the event of a
successful claim of product infringement against the Company and failure or
inability of the Company to develop non-infringing technology or license the
infringed or similar technology, the Company's business, financial condition
and results of operations could be materially adversely affected. In addition,
the Company may initiate claims or litigation against third parties for
infringement of the Company's proprietary rights or to establish the validity
of the Company's proprietary rights. Any such claims could be time consuming,
result in costly litigation, or lead the Company to enter into royalty or
licensing agreements rather than litigating such claims on their merits.
Moreover, an adverse outcome in
 
                                      11
<PAGE>
 
litigation or similar adversarial proceedings could subject the Company to
significant liabilities to third parties, require expenditure of significant
resources to develop non-infringing technology, require disputed rights to be
licensed from others or require the Company to cease the marketing or use of
certain products, any of which could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business--Intellectual Property and Other Proprietary Rights."
 
PRODUCT ERRORS; PRODUCT LIABILITY
 
  Software products as complex as those offered by the Company often contain
undetected errors or failures when first introduced or as new versions are
released. Testing of the Company's products is particularly challenging
because it is difficult to simulate the wide variety of computing environments
in which the Company's customers may deploy those products. Accordingly, there
can be no assurance that, despite testing by the Company and by current and
potential customers, errors will not be found after commencement of commercial
shipments, resulting in loss of or delay in market acceptance and negative
publicity about the Company and its products, any of which could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
  The Company's license agreements with customers typically contain provisions
designed to limit the Company's exposure to potential product liability
claims. The limitation of liability provisions contained in such license
agreements may not be effective under the laws of some jurisdictions,
particularly if the Company in the future relies on "shrink wrap" licenses
that are not signed by licensees. The Company's products are generally used to
manage data critical to organizations, and as a result, the sale and support
of products by the Company may entail the risk of product liability claims. A
successful liability claim brought against the Company could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business--Product Development."
 
RELIANCE ON TCP/IP AND MAINTENANCE; CONCENTRATION OF PRODUCT SALES
 
  During the fiscal year ended June 30, 1995 and the nine months ended March
31, 1996, sales of the TCPaccess products, excluding maintenance and hardware,
accounted for approximately 34% and 36%, and, including related maintenance
and hardware, accounted for approximately 66% and 68%, respectively, of the
Company's total revenues. Accordingly, the Company's operating results,
particularly in the near term, are significantly dependent upon the continued
market acceptance of the TCPaccess products. During the fiscal year ended June
30, 1995 and the nine months ended March 31, 1996, maintenance and consulting
revenue accounted for approximately 42% and 44%, respectively, of the
Company's total revenues. A portion of the maintenance revenues are from
historical customers of the Company's DECnet product. The Company no longer
actively markets the DECnet product, and maintenance revenues from DECnet
customers have declined each year since the fiscal year ended June 30, 1993,
and are expected to continue to decline. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations." The life cycles of
the Company's products are difficult to estimate due in part to the effect of
future product enhancements and competition. A decline in the demand for the
Company's products as a result of competition, technological change or other
factors would have a material adverse effect on the Company's business,
financial condition and results of operations.
 
  The Company estimates that the total number of potential sites where its
TCPaccess products could be installed is limited. Many of those sites have
already been serviced by either IBM or the Company. The Company expects that
it will continue to depend upon this limited number of prospective customers
for a significant portion of its revenues in future periods. As a result of
this concentration, the Company's business, financial condition and results of
operations could be materially adversely affected by the failure of
anticipated orders to materialize and by deferrals or cancellations of orders
as a result of changes in customer requirements. In addition, the Company's
future success depends upon the capital spending patterns of such customers
and the continued demand by such customers for the Company's products. The
Company's operating results may in the future be subject to substantial
period-to-period fluctuations as a consequence of such concentration and
factors affecting capital spending in the enterprise networked systems
management market.
 
                                      12
<PAGE>
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company is highly dependent on the continued service of, and on its
ability to attract and retain, qualified technical, sales, marketing and
managerial personnel, in particular, its key New Era employees. While the
Company intends to expand its field sales force, experienced field sales
personnel in the Company's industry are in high demand and may not be
attracted and retained on terms advantageous to the Company. Furthermore,
there can be no assurance that the Company's efforts to expand its field sales
force will be successful. The competition for qualified personnel in the
software industry is intense, and the loss of any such persons, as well as the
failure to recruit additional key personnel in a timely manner, could have a
material adverse effect on the Company's business, financial condition and
results of operations. There can be no assurance that the Company will be able
to continue to attract and retain the qualified personnel necessary for the
development of its business. The Company has employment agreements with
certain executive officers, but such agreements do not ensure their continued
service to the Company or prevent their competition with the Company following
a termination of employment. The Company does not maintain key man life
insurance on the lives of its key employees. See "Business--Employees,"
"Management--Executive Officers and Directors" and "--Employment Agreements
and Change in Control Arrangements."
 
LEGAL DISPUTE
 
  The Company and the Company's subsidiary in France are involved in a
commercial dispute with Selesta, a former Italian distributor of the Company's
TCPaccess products. Selesta alleged in a letter sent to the Company that the
Company had breached and unlawfully terminated the agreement pursuant to which
Selesta was appointed a distributor of the Company's products in Italy and
asserted other related claims against the Company. The letter demanded
Selesta's reinstatement as a distributor, the execution of a written
distribution agreement setting forth the distribution arrangements between the
parties, and compensation in an unspecified amount to be paid to Selesta for
the harm that it has suffered. The Company's Canadian subsidiary, New Era, has
also used Selesta as a distributor of the HARBOR products in Italy pursuant to
a separate agreement and may or may not continue to do so in the future. No
legal claim has been filed nor has arbitration been invoked by Selesta
regarding this matter. Should Selesta initiate legal proceedings and prevail
on such claims, the Company's business, financial condition and results of
operations could be materially adversely affected. See "Business--Legal
Dispute."
 
NO PRIOR TRADING MARKET; POSSIBLE VOLATILITY OF SHARE PRICE
 
  Prior to this offering there has been no public market for the Company's
Common Stock, and there can be no assurance that an active trading market will
develop or be sustained after this offering. The initial public offering price
of the Common Stock offered hereby will be determined through negotiations
among the Company, the representatives of the Selling Stockholders and the
Representatives of the Underwriters, and may not be indicative of future
market prices. There can be no assurance that the market price of the Common
Stock will not decline below the initial public offering price. The trading
prices of the Company's Common Stock may be subject to wide fluctuations in
response to a number of factors, including variations in operating results,
changes in earnings estimates by securities analysts, announcements of
extraordinary events such as litigation or acquisitions, announcements of
technological innovations or new products or new contracts by the Company or
its competitors, announcements and reports about the declining number of
mainframe computers shipped, press releases or reports of IBM or other
competitors introducing competitive or substitute products, as well as general
economic, political and market conditions. In addition, the stock market has
from time-to-time experienced significant price and volume fluctuations that
have particularly affected the market prices for the common stocks of
technology companies and that have often been unrelated to the operating
performance of particular companies. These broad market fluctuations may also
adversely affect the market price of the Company's Common Stock. In the past,
following periods of volatility in the market price of a company's securities,
securities class action litigation has occurred against the issuing company.
There can be no assurance that such litigation will not occur in the future
with respect to the Company. Such litigation could result in substantial costs
and a diversion of management's attention and resources, which could have a
material adverse effect on
 
                                      13
<PAGE>
 
the Company's business, financial condition and results of operations. Any
adverse determination in such litigation could also subject the Company to
significant liabilities.
 
CONTROL BY CURRENT STOCKHOLDERS
 
  The Company's officers, directors and principal stockholders and their
affiliates will in the aggregate beneficially own approximately 50% of the
Company's outstanding shares of Common Stock after this offering. As a result,
these stockholders, acting together, would be able to effectively control most
matters requiring approval by the stockholders of the Company, including the
election of directors and any merger, consolidation or sale of all the
Company's assets. See "Principal and Selling Stockholders" and "Description of
Capital Stock."
 
POTENTIAL IMPACT OF SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
  Sales of substantial amounts of Common Stock in the public market after the
offering could adversely affect the market price of the Company's Common
Stock. In addition to the 4,000,000 shares offered hereby, as of the effective
date of the Registration Statement (the "Effective Date"), 125,822 shares of
Common Stock will become eligible for sale in the public market in reliance on
Rule 144(k) under the Securities Act of 1933, as amended (the "Securities
Act"). Approximately 5,690,068 shares of Common Stock will become eligible for
sale in the public market, subject to compliance with Rules 144 and 701 under
the Securities Act, when certain 180-day lock-up agreements between the
Company and/or the Representatives and certain stockholders of the Company,
including officers, directors and Selling Stockholders, expire. In addition,
holders of warrants exercisable into an aggregate of 701,984 shares of Common
Stock have entered into 180-day lock-up agreements and no such shares may be
sold 180 days after commencement of this offering upon exercise. Upon
expiration of the lock-up agreements and assuming the warrants are then
exercised for cash, the shares acquired upon exercise of the warrants, in the
absence of registration, may only be publicly resold pursuant to Rule 144.
Furthermore, all of the optionholders are subject to a 180-day lock-up period
pursuant to their option agreements and the holders of 100% of the shares of
Common Stock subject to options have entered into the same 180-day lock-up
agreements as referenced above. Montgomery Securities may, in its sole
discretion, and at any time without notice, release all or any portion of the
securities subject to such lock-up agreements.
 
  The Company intends to file a registration statement under the Securities
Act covering approximately 4,379,275 shares of Common Stock issued or reserved
for issuance under the 1992 Stock Option Plan, the 1996 Employee Stock
Purchase Plan and the 1996 Director Option Plan. That registration statement
is expected to be filed within 90 days after the date of this Prospectus and
will automatically become effective upon filing. Accordingly, all the shares
registered under that registration statement will, subject to Rule 144 volume
limitations applicable to affiliates, as that term is defined in the
Securities Act, be available for resale in the open market on such date. At
March 31, 1996, options to purchase 2,015,455 shares were issued and
outstanding under the 1992 Stock Option Plan, 1,083,295 of which were vested
and eligible for exercise as of that date. See "Management--Stock Plans" and
"Shares Eligible for Future Sale."
 
  After the closing of the offering, the holders of up to 6,119,936 issued or
issuable shares of Common Stock, of which 988,334 shares are issuable upon
exercise of warrants, will be entitled to certain demand and piggyback rights
with respect to the registration of those shares under the Securities Act.
Demand registration rights will be exercisable commencing six months after the
Effective Date. If the holders of registration rights cause a large number of
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. See
"Description of Capital Stock--Registration Rights."
 
  Holders of 6,429,552 shares of Common Stock of the Company have agreed with
the Company and/or the Representatives that until 180 days after the Effective
Date, they will not sell, offer to sell, contract to sell or otherwise sell,
dispose of, loan, pledge or grant any rights with respect to any shares of
Common Stock, any options or warrants to purchase shares of Common Stock, or
any securities convertible or exchangeable for shares of Common Stock, owned
directly by such holders or with respect to which they have power of
 
                                      14
<PAGE>
 
disposition, without the prior written consent of the Company and/or
Montgomery Securities, as the case may be. The Company has agreed with the
Representatives not to release any holders from such agreements without the
prior written consent of Montgomery Securities. The Company has also agreed
not to sell, offer to sell, contract to sell, grant any option to purchase or
otherwise dispose of any shares of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock or any rights to acquire
Common Stock for a period of 180 days after the Effective Date without the
prior written consent of Montgomery Securities, subject to certain limited
exceptions including sales of shares under the stock plans. The lock-up
agreements with the Representatives may be released at any time as to all or
any portion of the shares subject to such agreements at the sole discretion of
Montgomery Securities.
 
ANTI-TAKEOVER EFFECT OF DELAWARE LAW AND CERTAIN CHARTER AND BYLAWS PROVISIONS
 
  Certain provisions of the Company's Certificate of Incorporation and Bylaws
may have the effect of making it more difficult for a third party to acquire,
or discouraging a third party from attempting to acquire control of
the Company. Such provisions could limit the price that certain investors
might be willing to pay in the future for shares of the Company's Common
Stock. Certain of these provisions provide for the elimination of the right of
stockholders to act by written consent without a meeting and specify
procedures for director nominations by stockholders and submission of other
proposals for consideration at stockholder meetings. In addition, the
Company's Board of Directors has the authority to issue up to 5,000,000 shares
of Preferred Stock and to determine the price, rights, preferences, privileges
and restrictions of those shares without any further vote or action by the
stockholders. The rights of the holders of Common Stock will be subject to,
and may be adversely affected by, the rights of the holders of any Preferred
Stock that may be issued in the future. The issuance of Preferred Stock, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult
for a third party to acquire a majority of the outstanding voting stock of the
Company. The Company has no present plans to issue shares of Preferred Stock.
Certain provisions of Delaware law applicable to the Company could also delay
or make more difficult a merger, tender offer or proxy contest involving the
Company, including Section 203 of the Delaware General Corporation Law, which
prohibits a Delaware corporation from engaging in any business combination
with any interested stockholder for a period of three years unless certain
conditions are met. The inability of stockholders to act by written consent
without a meeting, the procedures required for director nominations and
stockholder proposals and Delaware law could have the effect of delaying,
deferring or preventing a change in control of the Company, including without
limitation, discouraging a proxy contest or making more difficult the
acquisition of a substantial block of the Company's Common Stock. These
provisions could also limit the price that investors might be willing to pay
in the future for shares of the Company's Common Stock. See "Description of
Capital Stock--Preferred Stock," "--Certain Provisions of the Certificate of
Incorporation and Bylaws" and "--Certain Provisions of Delaware Law."
 
DILUTION
 
  Purchasers of the Common Stock offered hereby will experience immediate,
substantial dilution in the net tangible book value per share of the Common
Stock from the initial public offering price. See "Dilution."
 
 
                                      15
<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of 2,000,000 shares of Common
Stock offered by the Company hereby are estimated to be approximately $17.7
million ($23.3 million if the over-allotment option is exercised in full),
based on an assumed initial public offering price of $10.00 per share, after
deducting underwriting discounts and commissions and estimated offering
expenses. The Company will not receive any of the proceeds from the sale of
Common Stock by the Selling Stockholders.
 
  From these estimated net proceeds, the Company will repay the outstanding
balance of the Company's domestic bank line of credit of approximately $5.0
million at March 31, 1996, which borrowings bear interest at prime plus 1.5%
per annum and mature in November 1996. If the over-allotment option is
exercised in full, the Company intends to repay the outstanding balance of the
Company's long-term note of approximately $3.0 million at March 31, 1996,
which borrowings bear interest at prime plus 2.5% per annum and mature in
December 1998. The bank line of credit and the long-term note were incurred in
connection with the acquisition of New Era. In addition, the Company currently
expects to utilize $500,000 of the net proceeds to the Company from the
offering for capital expenditures, including expanding the Company's customer
support system. The remaining net proceeds to the Company from the offering
will be used for working capital and other general corporate purposes. The
Company may use a portion of the net proceeds for the acquisition of
complementary businesses and technologies or for the implementation of various
corporate partnering arrangements. However the Company has no present
understandings, commitments or agreements, nor is it currently engaged in any
discussions or negotiations with respect to any such transaction, except for
the development of HARBOR Agent for Networker in connection with the strategic
alliance with Legato. Pending such uses, the Company intends to invest the net
proceeds in short-term, investment grade interest bearing securities.
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid cash dividends on its Common Stock.
The Company intends to retain its earnings, if any, to fund its business and
therefore does not anticipate paying cash dividends in the foreseeable future.
The Company's bank line of credit agreement contains a restrictive covenant
which limits the Company's ability to pay cash dividends or make stock
purchases without the prior written consent of the lender. See Note 4 of Notes
to Consolidated Financial Statements.

                                   DILUTION
 
  The pro forma net tangible negative book value of the Company at March 31,
1996 was approximately $(8.3) million, or $(1.12) per share of Common Stock.
Pro forma net tangible negative book value per share represents the amount of
total tangible assets less total liabilities, divided by the number of shares
of Common Stock then outstanding (assuming the conversion of all then
outstanding Preferred Stock into Common Stock). After giving effect to the
sale by the Company of the 2,000,000 shares of Common Stock offered by the
Company hereby (at an assumed initial public offering price of $10.00 per
share and after deduction of estimated underwriting discounts and commissions
and offering expenses), the Company's pro forma net tangible book value at
March 31, 1996 would have been $9.4 million, or $0.98 per share of Common
Stock. This represents an immediate increase in net tangible book value of
$2.10 per share to existing stockholders and an immediate dilution of $9.02
per share to investors purchasing shares in this offering. The following table
illustrates the per share dilution:

  The following table summarizes, on a pro forma basis as of March 31, 1996,

(1) Sales by the Selling Stockholders in this offering will reduce the number
    of shares of Common Stock held by existing stockholders to 5,557,249 or
    approximately 58% (5,557,249 shares, or approximately 55%, if the
    Underwriters' over-allotment option is exercised in full) and will
    increase the number of shares held by new investors to 4,000,000 or
    approximately 42% (4,600,000 shares, or approximately 45%, if the
    Underwriters' over-allotment option is exercised in full) of the total
    number of shares of Common Stock outstanding after this offering. See
    "Principal and Selling Stockholders."
 
  The foregoing computations assume no exercise of stock options or warrants
after March 31, 1996, except for the net exercise of warrants for 150,000
shares of Common Stock which warrants expire upon the closing of this
offering. As of March 31, 1996, there were outstanding options to purchase
2,015,455 shares of Common Stock, with a weighted average exercise price of
$0.55 per share and warrants to purchase 988,334 shares of Common Stock with a
weighted average exercise price of $1.48 per share. In addition, as of March
31, 1996, 74,171 shares of Common Stock were reserved for future issuance
under the Company's 1992 Stock Option Plan. To the extent that any shares
available for issuance upon exercise of outstanding options or warrants or
reserved for future issuance under the Company's stock plans are issued, there
will be further dilution to new investors. See "Management--Stock Plans,"
"Description of Capital Stock" and Note 7 of Notes to Consolidated Financial
Statements.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains forward-looking statements that involve
risks and uncertainties. The Company's actual results could differ materially
from those anticipated in these forward-looking statements as a result of
certain factors, including those set forth under "Risk Factors" and elsewhere
in this Prospectus.
 
OVERVIEW
 
  The Company offers a suite of high-performance, network transport products
and systems management applications which efficiently transport, store and
protect the integrity of mission-critical data and applications. The Company
was incorporated in December 1985 and initially focused its products and
development on providing interoperability between IBM mainframes and DECnet
network environments. In 1990, the Company acquired the core technology of its
TCPaccess suite of products. In January 1996, the Company began offering its
HARBOR products through the acquisition of New Era Systems Services, Ltd.
("New Era"). HARBOR is a software product line providing enterprise systems
management applications for client/server networks. New Era is a wholly-owned
subsidiary headquartered in Calgary, Alberta with 36 full time employees, as
of March 31, 1996. The Company is operating the New Era development and
support teams as the HARBOR division of Interlink.
 
  The Company acquired New Era in exchange for cash and notes payable totaling
$12.4 million and warrants to purchase 700,000 shares of the Company's Common
Stock with additional contingent earnout payments of up to a total of
$5.2 million due January 31, 1997 and 1998. Because the New Era acquisition
was accounted for as a purchase, the Company's operating results only include
the results of New Era operations subsequent to December 29, 1995, the
acquisition date. As a result, comparisons of results for the nine months
ended March 31, 1996 and 1995 are not meaningful. For the quarter ended
December 31, 1995, the Company charged to operations approximately
$10.2 million of purchased research and development in connection with the New
Era acquisition. The Company's future operating costs will include the
amortization of intangible assets arising from the acquisition of New Era. At
March 31, 1996, remaining intangible assets derived from the New Era
acquisition total approximately $3.0 million and are being amortized over a
five-year period. The amortization is expected to be approximately $160,000
per quarter through December 31, 2000, but may increase after December 31,
1996 if certain contingent payments are made, based upon meeting revenue
targets for calendar years 1996 and 1997. See Note 2 of Notes to Consolidated
Financial Statements.
 
  The Company's revenues are derived from product sales and related
maintenance and consulting contracts. Product revenues are derived from
software license fees and sales of related hardware to end users, resellers
and distributors. The Company's sales cycle, from the date the sales agent
first contacts a prospective customer to the date a customer ultimately
purchases the Company's product, is typically three to six months for the
TCPaccess products and six to nine months for the HARBOR products. Typically,
a customer purchases the Company's products following a trial period. Because
licenses are noncancellable and do not impose significant obligations on the
Company, the Company recognizes software license revenues upon completion of
the trial period and a signed contract. Fees for service revenues are charged
separately from the Company's product sales. The Company recognizes revenues
ratably over the term of agreement. Maintenance agreements are typically one-
year renewable contracts, pursuant to which, historically, a substantial
majority of the Company's maintenance agreements have been renewed upon
expiration. However, there can be no assurance that customers will continue to
renew expiring maintenance agreements at the historical rate. The Company
recognizes consulting revenues as services are accepted.
 
  The Company currently derives substantially all of its product revenues from
its TCPaccess software and related hardware products and services. Although
the Company expects HARBOR products to contribute more substantially to the
Company's product revenues in future periods, broad market acceptance for
TCPaccess and HARBOR is critical to the Company's success. Failure to achieve
broad market acceptance of TCPaccess and
 
                                      21
<PAGE>
 
HARBOR, as a result of competition, technological change or otherwise, would
have a material adverse effect on the business, financial condition and
results of operations of the Company. The Company's future performance will
depend in large part on continued growth in the number of organizations
adopting enterprise networked systems management products, and the Company's
successful development, introduction and customer acceptance of new and
enhanced versions of its software products. There can be no assurance that the
market for enterprise networked systems management products will grow or that
the Company will continue to be successful in marketing TCPaccess or HARBOR or
any new or enhanced products.
 
  The Company's maintenance revenues are derived primarily from its TCPaccess
and DECnet product lines. The Company expects maintenance revenue from its
HARBOR line to grow in relation to growth in the HARBOR customer base. The
Company no longer actively markets its DECnet product line. As a consequence,
license revenues from this product line have declined substantially, although
the Company continues to provide maintenance to its installed DECnet
customers. Total revenues from the Company's DECnet product line were $11.6
million, $8.5 million, $7.1 million, and $5.1 million for the fiscal years
ended June 30, 1993, 1994 and 1995 and for the nine months ended March 31,
1996, respectively. Maintenance revenues from the DECnet product were $7.5
million, $6.6 million, $6.5 million and $4.6 million for the fiscal years
ended June 30, 1993, 1994 and 1995 and for the nine months ended March 31,
1996, respectively. The Company expects that maintenance revenues from this
product line will continue to decline in the future.
 
  The Company licenses its software in U.S. dollars and certain foreign
currencies. The Company has experienced foreign currency exchange gains and
losses. The Company expects that fluctuations in foreign currencies may have a
significant impact on either its revenues or expenses in the future. See "Risk
Factors--Reliance on and Risks Associated with International Sales."
 
  The Company completed a recapitalization in October 1992 in which all
previously outstanding Preferred Stock was converted to Common Stock and the
Company restructured its bank lines of credit. At that time, the Company hired
new members of its management team including a new chief executive officer and
chief financial officer. The financial statements of the Company for the
fiscal years ended June 30, 1991 and 1992 were restated due to material
misstatements contained in such financial statements resulting from misconduct
involving the preparation of accounting records, particularly in regard to the
recording of revenue. No officer of the Company at the time any such
misconduct occurred is currently an employee or officer of the Company.
Although one director at the time remains a director, the Company believes
that such director was not involved in such misconduct.

NINE MONTHS ENDED MARCH 31, 1995 AND 1996
 
  As a result of the acquisition of New Era in December 1995, the Company's
operating results for the nine months ended March 31, 1995 and 1996 are not
directly comparable. The results of the Company's operations for the first
nine months of fiscal 1996 are not representative of the combined anticipated
results of operations of the Company and New Era.
 
 Revenues
 
  Total revenues were $18.5 million and $23.7 million for the nine months
ended March 31, 1995 and 1996, respectively, representing an increase of 28%.
Product sales were $10.2 million and $13.2 million for the nine months ended
March 31, 1995 and 1996, respectively, representing an increase of 30%. This
increase was primarily due to increased TCPaccess license fees as well as the
addition of revenues from HARBOR products.
 
                                      23
<PAGE>
 
Maintenance and consulting revenues were $8.4 million and $10.5 million for
the nine months ended March 31, 1995 and 1996, respectively, representing an
increase of 26%, resulting principally from an increase in the number of
customers purchasing maintenance agreements.
 
 Cost of Revenues
 
  Product. Cost of revenues from product sales consists primarily of hardware,
product media, documentation and packaging costs. Cost of revenues for product
sales was $2.4 million and $2.3 million, representing 23% and 17% of total
product revenues for the nine months ended March 31, 1995 and 1996,
respectively. This decrease was due to a reduction in third-party product
revenue and a decline in hardware revenue, which carry higher product costs as
a percentage of their respective revenue items.
 
  Maintenance and Consulting. Cost of revenues from maintenance and consulting
consists primarily of personnel related costs incurred in providing telephone
support and software updates. Cost of revenues from maintenance and consulting
was $2.3 million and $3.3 million, representing 28% and 32% of total
maintenance and consulting revenues for the nine months ended March 31, 1995
and 1996, respectively. This increase is due to added headcount in the
worldwide customer support department required to keep pace with the increased
product sales from period to period.
 
 Operating Expenses
 
  Total operating expenses were $15.1 million and $25.8 million, representing
81% and 109% of total revenues for the nine months ended March 31, 1995 and
1996, respectively. Excluding the charge for purchased research and
development related to the New Era acquisition, the operating expenses for the
nine months ended March 31, 1996 were $15.7 million representing 66% of total
revenues.
 
  Product Development. Product development expenses consist primarily of
personnel related costs. Product development expenses were $5.1 million and
$3.8 million, representing 28% and 16% of total revenues for the nine months
ended March 31, 1995 and 1996, respectively. The reduction in product
development expenses resulted from the cancellation in March 1995 of a
significant product development program. The Company believes that research
and development expenses will increase in the future primarily as a result of
the acquisition of New Era and other anticipated product development efforts.
 
  Product development expenditures are generally charged to operations as
incurred. Statement of Financial Accounting Standards No. 86, "Accounting for
the Costs of Computer Software to be Sold, Leased or Otherwise Marketed,"
requires capitalization of certain software development costs subsequent to
the establishment of technological feasibility. Based on the Company's product
development process, technological feasibility is established upon completion
of a working model. Costs incurred by the Company between completion of the
working model and the point at which the product is ready for general release
have not been significant in recent periods.
 
  Sales and Marketing. Sales and marketing expenses consist primarily of
salaries and commissions for sales and marketing personnel, the fixed costs of
worldwide field offices, and promotional costs. The Company sells through its
direct sales force, resellers and distributors. The direct channel produced
88% and 86% of product revenues for the nine months ended March 31, 1995 and
1996, respectively, and is also the major component of sales channel costs.
Sales and marketing expenses were $7.4 million and $8.9 million, representing
40% and 37% of total revenues for the nine months ended March 31, 1995 and
1996. The increase in absolute dollars was a result of higher commission
rates, marketing program costs and the New Era acquisition. The Company
believes that sales and marketing expenses will increase in absolute dollar
amount as the Company continues to expand its sales force for both HARBOR and
TCPaccess and launch new corporate marketing programs.
 
  General and Administrative. General and administrative expenses include
personnel and other costs of the finance, human resources and administrative
departments of the Company, and includes gains and losses on
 
                                      24
<PAGE>
 
foreign currency exchange. General and administrative expenses were $2.6
million and $2.9 million, representing 14% and 12% of total revenues for the
nine months ended March 31, 1995 and 1996, respectively. The increase in
dollar amounts for general and administrative is attributable to the increased
headcount required to support the Company's expansion and an increase in
allowance for doubtful accounts.
 
  Purchased Research and Development and Product Amortization. Purchased
research and development expense incurred in connection with the New Era
acquisition was approximately $10.2 million, representing 43% of total
revenues for the nine months ended March 31, 1996. In addition, approximately
$160,000 of product amortization resulting from such acquisition was included
in the quarter ended March 31, 1996. See Note 2 of Notes to Consolidated
Financial Statements.
 
  Interest Expense, net. Net interest expense was $100,000 and $220,000 for
the nine months ended March 31, 1995 and 1996, respectively. The increase was
due primarily to bank borrowings related to the New Era acquisition which were
outstanding for the quarter ended March 31, 1996.
 
  Benefit from (Provision for) Income Taxes. The income tax provision for the
nine months ended March 31, 1995 was zero, with a tax benefit of $67,000
recorded for the nine months ended March 31, 1996. The effective tax rate for
the nine months ended March 31, 1996 was approximately 1%, which is net of the
approximate 39% benefit relating to the recognition of the Company's deferred
tax asset. Excluding the impact of the Company's deferred tax asset, the tax
rate would be 39%. Effective January 1, 1993, the Company adopted Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS
109"). The current and cumulative effects of the adoption of SFAS 109 were not
material to the Company's financial position or results of operations. See
Note 8 of Notes to Consolidated Financial Statements.
 
FISCAL YEARS ENDED JUNE 30, 1993, 1994 AND 1995
 
 Revenues
 
  Total revenues were $21.2 million, $21.9 million and $27.1 million for the
fiscal years ended June 30, 1993, 1994 and 1995, respectively, representing
increases of 3% from fiscal 1993 to fiscal 1994 and 24% from fiscal 1994 to
fiscal 1995. International revenues accounted for 39%, 37% and 42% of total
revenues for the fiscal years ended June 30, 1993, 1994 and 1995,
respectively. The increase in international revenues in fiscal 1995 was
primarily attributable to an increase in the market acceptance of the
Company's products overseas and an increase in the number of international
sales offices, distributors and resellers selling the Company's products. The
Company established a sales and support office in Switzerland during fiscal
1994 and a sales and support office in Spain during fiscal 1995.
 
  Product. Product revenues were $11.9 million, $12.4 million and $15.8
million for the fiscal years ended June 30, 1993, 1994 and 1995, respectively,
representing increases of 4% from fiscal 1993 to fiscal 1994 and 28% from
fiscal 1994 to fiscal 1995. The increases from year to year are primarily the
result of increased sales of TCPaccess which reflect the accelerated
acceptance of TCP/IP as a networking protocol. Product revenues derived from
hardware product sales were $3.2 million, $2.8 million and $4.0 million for
the fiscal years ended June 30, 1993, 1994 and 1995, respectively.
 
  Maintenance and Consulting. Maintenance and consulting revenues were $9.3
million, $9.5 million and $11.3 million, representing 44%, 44% and 42% of
total revenues for the fiscal years ended June 30, 1993, 1994 and 1995,
respectively, and represented increases of 3% from fiscal 1993 to fiscal 1994
and 18% from fiscal 1994 to fiscal 1995. These increases were primarily due to
an increase in the number of registered customers electing to subscribe to
maintenance and support contracts after the expiration of the warranty period,
which is generally 90 days. The modest increase in maintenance from fiscal
1993 to fiscal 1994 reflects an increase in associated TCPaccess maintenance
agreements somewhat offset by a decline in maintenance renewals for the DECnet
product line. The increase from fiscal 1994 to fiscal 1995 parallels the
overall higher increase in product revenues. In fiscal 1995, the Company began
to sell consulting services.
 
                                      25
<PAGE>
 
 Cost of Revenues
 
  Product. Cost of revenues from product sales was $2.7 million, $2.4 million
and $3.3 million, representing 22%, 19% and 21% of the related revenues for
the fiscal years ended June 30, 1993, 1994 and 1995, respectively. The
increase in cost of revenues in absolute dollars and as a percentage of total
revenues from fiscal 1994 to fiscal 1995 is primarily related to an increase
in third-party product revenue, which carry a higher cost of revenues than the
Company's software products. The decrease in cost of revenues as a percentage
of the related revenues in fiscal 1994 and fiscal 1995 compared to fiscal 1993
was attributable to a decrease in the percentage of hardware revenue.
 
  Maintenance and Consulting. Cost of revenues from maintenance and consulting
was $1.4 million, $1.4 million and $3.3 million, representing 15%, 15% and 29%
of the related revenues for the fiscal years ended June 30, 1993, 1994 and
1995, respectively. The increase in cost of revenues in fiscal 1995 as a
percentage of related revenues compared to fiscal 1993 and fiscal 1994 was
attributable to added headcount in worldwide customer support and consulting
and a change in the estimate for the recoverability of support inventory.
 
 Operating Expenses
 
  Product Development. Product development expenses were $5.0 million, $6.3
million and $6.2 million, representing 24%, 29% and 23% of total revenues for
the fiscal years ended June 30, 1993, 1994 and 1995, respectively. Product
development expenses increased in fiscal 1994 due to increased staffing for
software engineers required to research and develop new client/server
technology. In fiscal 1995, the Company canceled its research investment in
new technology and reduced the staffing levels in research and development.
 
  Sales and Marketing. Sales and marketing expenses were $6.6 million, $8.4
million and $10.8 million, representing 31%, 38% and 40% of total revenues for
the fiscal years ended June 30, 1993, 1994 and 1995, respectively. Sales and
marketing expenses increased in such periods due to the opening of two
international subsidiaries, expansion of the Company's sales force and
associated support staff, increased marketing and promotional activities and
increased commission expenses.
 
  General and Administrative. General and administrative expenses were $3.3
million, $2.6 million and $3.3 million, representing 15%, 12% and 12% of total
revenues for the fiscal years ended June 30, 1993, 1994 and 1995,
respectively. The increases in absolute dollars in fiscal 1995 compared to
fiscal 1994 were primarily the result of prior period adjustments for import
duties and sales tax liability.
 
  Interest Expense, net. Net interest expense was $387,000, $224,000, and
$81,000, for the fiscal years ended June 30, 1993, 1994, and 1995,
respectively. Net interest expense decreased year to year as bank borrowings
declined and as interest income increased due to higher invested cash
balances.
 
  Other Income. The Company recorded $1.0 million of other income related to a
transfer of technology for the fiscal year ended June 30, 1993.
 
  Benefit from (Provision for) Income Taxes. The Company recorded an income
tax benefit of $1.6 million in the fiscal year ended June 30, 1995, reflecting
partial reversal of the valuation allowance against the Company's deferred tax
asset. The income tax provision for the fiscal years ended June 30, 1993 and
1994 was $953,000 and $273,000, respectively.
 
  Extraordinary Items. The Company recognized a $1.1 million extraordinary
gain related to the utilization of net operating loss carryforward in fiscal
1993. In fiscal 1994, the Company recorded a gain of $1.3 million as the
result of restructuring debt with a commercial lender. See Note 5 of Notes to
Consolidated Financial Statements.

  The Company's business has experienced and is expected to continue to
experience significant seasonality. The Company has higher sales of its
software products in the quarters ending in December and June and weaker sales
in the quarters ending in September and March. The decrease in product
revenues in the quarters ending in September is due to the international
customer seasonal buying patterns. The quarters ending in March are
historically weak due to government and large organization annual budgeting
cycles. The Company believes this pattern will continue. The increase in
product revenues in the two most recent quarters is primarily attributable to
increased software license fees for the Company's TCPaccess product as well as
the sale of the HARBOR product internationally. The decrease in product
revenues in the quarter ended in March 31, 1995 also reflected the delay in
the release of Version 3.1 of TCPaccess until the quarter ended June 30, 1995.
The increase in maintenance and consulting revenue in the quarter ended
September 30, 1995 related primarily to delays in renewals of customer
maintenance agreements and increased consulting and a maintenance revenue
adjustment for prior periods.
 
  The Company's operating results have historically been, and will continue to
be, subject to quarterly and annual fluctuations due to a variety of factors,
including: timely introduction, enhancement and market acceptance of new
versions of the Company's products; seasonal customer demand; timing of
significant orders; changes in the pricing policies by the Company or its
competitors; anticipated and unanticipated decreases in unit average selling
prices of the Company's products; increased competition; changes in the mix of
the products sold and in the mix of sales by distribution channel; the gain or
loss of significant customers; the introduction of new products or product
enhancements by competitors; currency fluctuations; and the failure to
anticipate
 
                                      28
<PAGE>
 
changing customer product requirements. The Company's sales cycle, from the
date the sales agent first contacts a prospective customer to the date a
customer ultimately purchases the Company's product, is typically three to six
months for the TCPaccess products and six to nine months for the HARBOR
products. There can be no assurance that the Company's sales cycle will not
lengthen, exposing it to the possibility of shortfalls in quarterly revenues,
which could have a material adverse effect on the Company's business,
financial condition or results of operations, and cause results to vary from
period to period. The Company's operating results will also be affected by
general economic and other conditions affecting the timing of customer orders
and capital spending, and order cancellations or rescheduling. The Company
operates with very little backlog and most of its product revenues in each
quarter result from orders closed in that quarter, and a substantial majority
of those orders are completed at the end of that quarter. The Company
establishes its expenditure levels for sales, marketing, product development
and other operating expenses based in large part on its expectations as to
future revenues, and revenue levels below expectations could cause expenses to
be disproportionately high. If revenues fall below expectations in a
particular quarter, operating results and net income are likely to be
materially adversely affected. Any inability of the Company to adjust spending
to compensate for failure to meet sales forecasts or to collect accounts
receivable, or any unexpected increase in product returns or other costs,
could magnify the adverse impact of such events on the Company's operating
results. Due to the foregoing factors, quarterly revenue and operating results
are likely to vary significantly in the future and period-to-period
comparisons of its results of operations are not necessarily meaningful and
should not be relied upon as indications of future performance.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since the beginning of fiscal 1993, the Company has financed its operations
primarily through private sales of Preferred Stock, totaling $6.7 million,
bank borrowings and cash generated from operations. Net cash provided by (used
in) operating activities was $1.9 million, $(1.4) million, $2.2 million and
$3.6 million for the fiscal years ended June 30, 1993, 1994 and 1995 and for
the nine months ended March 31, 1996, respectively. Net cash provided by
operating activities in fiscal 1993 consisted primarily of the net income and
depreciation and amortization, partially offset by a decrease in accrued
expenses. Net cash used in operating activities in fiscal 1994 consisted
primarily of an increase in accounts receivable and a non-cash gain on debt
restructuring, partially offset by net income. Net cash provided by operating
activities in fiscal 1995 consisted primarily of the net income, depreciation
and amortization and an increase in accrued liabilities, partially offset by
an increase in deferred income taxes. Net cash provided by operating
activities for the nine months ended March 31, 1996 consisted primarily of
purchased research and development partially offset by a net loss. Net cash
used in investing activities was $492,000, $952,000, $2.6 million and $7.9
million for the fiscal years ended June 30, 1993, 1994 and 1995 and for the
nine months ended March 31, 1996, respectively. Net cash used in investing
activities in fiscal 1993 and fiscal 1994 related to the acquisition of
property and equipment and capitalization of software development costs. Net
cash used in fiscal 1995 consisted primarily of the purchase of available-for-
sale securities. Net cash used in investing activities for the nine months
ended March 31, 1996 was primarily due to the Company's acquisition of New
Era. Net cash provided by (used in) financing activities was $346,000, $4.5
million, $(1.4) million and $6.2 million for the fiscal years ended 1993, 1994
and 1995 and for the nine months ended March 31, 1996, respectively. Net cash
provided by financing activities in fiscal 1993 consisted primarily of
proceeds from issuance of Common Stock. Net cash provided by financing
activities in fiscal 1994 consisted primarily of proceeds from issuance of
Preferred Stock and proceeds from bank line of credit and notes payable to
stockholder, partially offset by payments on notes payable. Net cash provided
by financing activities in fiscal 1995 was primarily from payments on capital
lease and customer service obligations and payments on notes payable and bank
line of credit. Net cash provided by financing activities for the nine months
ended March 31, 1996 consisted primarily of proceeds from the bank line of
credit and term loan established for the New Era acquisition. The Company's
business is geographically dispersed resulting in a significant portion of its
cash residing outside of the United States. At March 31, 1996, 61% of the
Company's cash was in international bank accounts.
 
  Historically, the Company has not invested in derivative securities or any
other financial instruments that involve a high level of complexity or risk.
Management expects that, in the future, cash in excess of current requirements
will be invested in investment grade, interest-bearing securities.

  At March 31, 1996, the Company had $5.9 million in cash and cash equivalents
and $(6.3) million in working capital. The negative working capital balance at
March 31, 1996 resulted from the use of working capital in connection with the
acquisition of New Era in December 1995. The Company also has available a line
of credit agreement with a bank that expires on November 29, 1996, which is
collateralized by certain assets of the Company and permits borrowings of a
percentage of eligible accounts receivable and bears interest at the lender's
prime rate plus 1.5%. Under the terms of the agreement, the Company is
required to maintain a certain minimum quick ratio and tangible net worth and
maximum debt to tangible net worth, as well as quarterly profitability. At
March 31, 1996, $5.0 million was outstanding under the line of credit. In
addition, the Company has a note payable with a bank that is due on December
31, 1998, is collateralized by certain assets of the Company and bears
interest at the lender's prime rate plus 2.5%. Under the terms of the note,
the Company is required to maintain certain financial covenants. At March 31,
1996, $3.0 million was outstanding under the note. The Company had $8.1
million in accounts receivable, net of allowance for doubtful accounts, and
$9.0 million of unearned revenues, substantially all of which will be earned
over the 12-month period following March 31, 1996.
 
  Capital expenditures, including amounts financed under capital leases, have
remained relatively constant in recent periods, aggregating approximately
$461,000, $885,000, $721,000 and $273,000 for the fiscal years ended June 30,
1993, 1994 and 1995 and for the nine months ended March 31, 1996,
respectively. The Company had no material capital expenditure commitments at
March 31, 1996. The Company expects that it will have $1.1 million of capital
expenditures through March 31, 1997, including approximately $500,000 to
expand its customer support system.
 
  The Company believes that the net proceeds from the sale of the Common Stock
offered hereby, together with its current balances, cash available under its
line of credit and cash flow from operations, if any, will be sufficient to
meet its working capital and capital expenditure requirements at least through
December 31, 1997. 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 may use cash.
Consequently, any such future growth may require the Company to obtain
additional equity or debt financing, which may not be available or may be
dilutive.

OVERVIEW
 
  Interlink Computer Sciences, Inc. ("Interlink" or the "Company") is a
leading supplier of high- performance solutions for enterprise networked
systems management. Interlink provides software and services which enable
customers implementing client/server systems to use their IBM and IBM-
compatible MVS mainframes as "enterprise servers" in distributed,
heterogeneous client/server network environments. The Company's products and
services enable customers to transport, access and manage mission-critical
data and applications across distributed network environments. The Company
develops and markets the TCPaccess products which provide for enterprise
server TCP/IP connectivity, fault tolerance, and CICS-to-LAN application
integration. Interlink also develops and markets the HARBOR products for
network backup, archive and restore, and application, data and software
distribution. The Company also supplies network printing and other
applications which expand the functionality of the enterprise server. As of
March 31, 1996, the Company licensed its TCPaccess products to approximately
900 customer sites and its HARBOR products to over 160 customer sites
worldwide.
 
  The Company markets and sells its software and services primarily through
its direct sales organization and, to a lesser extent, through resellers and
international distributors. Significant customers which have purchased/
licensed the Company's products include the Internal Revenue Service, MACIF,
U.S. Sprint, W.R. Grace & Co. and Wells Fargo Bank. The Company recently
entered a strategic relationship with Legato to develop products which will
enable the companies to provide enterprise-class storage management solutions.
 
INDUSTRY BACKGROUND
 
  Many large organizations depend on centralized mainframe computer systems to
manage mission-critical software applications and to serve as the repository
for essential business data. These systems, along with sophisticated systems
management software, provide highly available computer processing resources,
are extremely reliable over extended periods of usage, are scalable to
accommodate a large number of users, and provide for secure movement and
storage of large amounts of data.
 
  Recently, advances in hardware, software, and networking technologies have
led to the deployment of client/server systems, in which computing tasks are
distributed throughout a network of computers. Organizations have adopted
client/server networks to obtain the advantages inherent in distributed
computing, such as independent local processing and storage of data, lower
initial cost, and efficient use of common software programs.
 
  Organizations are now integrating mainframe computers into their
client/server networks as "enterprise servers" which, like other servers on
the client/server network, have a specialized purpose and function.
Specifically, the enterprise server and the systems management applications
associated with its use have proven capable of providing reliable and
efficient systems management, data security, and distribution of data and
applications. Improvements in the cost-effectiveness of mainframe systems have
significantly increased the use of mainframe computers as enterprise servers.
 
  The integration of TCP/IP, an open systems transport protocol, with the IBM
MVS mainframe operating system, has enabled the connection of centralized
mainframes to distributed client/server networks on a peer-to-peer basis
regardless of the hardware or software used on such networks. Organizations
seeking distributed access to mainframe data, highly reliable computing
resources, and leverage from existing investments in
 
                                      31

hardware, applications and training, have seen the integration of the
enterprise server into the client/server network as a logical evolution.
Software is now available that allows client/server networks to take advantage
of the mainframe as an enterprise server. By recognizing this movement to
"network-centric" computing and incorporating TCP/IP functionality in recent
releases of the MVS operating system, IBM has also acknowledged the emergence
of the mainframe as an enterprise server. Organizations now can take advantage
of investments in mainframe computers and applications by leveraging these
investments across the client/server network.
 
  Organizations implementing client/server computing environments which
leverage the benefits of the enterprise server require rapid TCP/IP access and
a new class of software solutions to enable these previously disparate
computing environments to efficiently interoperate. At the network transport
level, the speed, efficiency and reliability of a given transport solution can
have a considerable impact on the effectiveness of the overall computing
environment, particularly as the volume of data stored and accessed across the
network increases. Organizations which implement high-performance efficient
network transport solutions are able to lower the computing burden on their
enterprise servers and increase the potential to defer costly hardware
upgrades. At the systems level, the complexity of networks with both
centralized and distributed resources creates the need for robust applications
to perform storage management, software distribution and output management.
Customers thus require both high-performance network transport products and
systems management applications to transport, store and protect critical data
and applications. Furthermore, users require a high level of customer service
and support as they strive to leverage the advantages of both centralized and
distributed architectures in a single seamless network.
 
THE INTERLINK SOLUTION
 
  Interlink's products enable MVS mainframes to function as enterprise servers
in client/server environments. The Company offers a suite of high-performance
network transport products and systems management applications which
efficiently transport, store and protect the integrity of mission-critical

client/server networks. With almost ten years of experience in the networked
systems management industry, Interlink provides networking solutions that
build upon its expertise in the integration of the MVS operating system with
TCP/IP and its reputation for high-performance, efficient products.
 
  The Company's principal network transport product, TCPaccess, connects the
MVS enterprise server to client/server networks using open systems TCP/IP
protocols. The Company's HARBOR and other systems management applications
backup data from, distribute software to, and allow printing across the
clients and servers on the network, which expands the functionality of the
enterprise server.

  The following examples are representative of how the Company's present
customers utilize TCPaccess and HARBOR in solving their network transport and
systems management needs. These examples have been prepared by the Company
based on information provided by the respective customer.
 
 University Medical Center
 
  A major university medical center with more than 1,000 patient beds and
10,000 employees sought to centralize the management of computerized patient
records, enable the collection of critical information from numerous sources,
such as physicians offices, surgery areas, test labs and pharmacy, and provide
data access wherever needed to assure that doctors, nurses and lab technicians
have up-to-date information. The university decided to integrate its mainframe
applications with numerous LANs and thousands of terminal devices located
across the campus. When the university standardized on TCP/IP as its
interconnectivity protocol, it selected Interlink to provide connectivity
between the mainframe and the LANs. The university installed TCPaccess,
Enterprise Print Services, and the CICS Toolkit for query processing to handle
both inbound and outbound telnet terminal sessions, file transfers and large
volumes of remote printing to the mainframe's page printers. Using Interlink's
capabilities, the university has been sending all of the major print jobs on
this system to the enterprise server. The university cited the Company's
superior customer support in addition to the functionality of the Company's
products as principal reasons for its decision to use the Company's products.
 
 Natural Gas Supplier
 
  A large supplier of industrial gases serving 2 million customers in Europe
is using TCPaccess to leverage the power of its mainframe resources to enhance
its client/server network. This customer's computer network in the United
Kingdom is used to ensure that its customers receive effective service
regardless of their geographic location. Historically, this customer used an
SNA network with approximately 2,000 terminals connected to an IBM mainframe.
In implementing its client/server environment this customer replaced its
terminals with PCs connected to Compaq servers running Windows NT, but wanted
to maintain the enterprise server to provide centralized data storage and
offer all users on the entire network a single point-of-contact for all key
customer information. As TCP/IP traffic increased, this customer's existing
TCP/IP product became less efficient. Switching to TCPaccess allowed this
customer to make more efficient use of its enterprise server by providing more
clients access to the central data store of the company.
 
 Banking Institutions
 
  Information is vital to the banking industry and protecting customer and
bank data is one of the foremost priorities at this major bank. This bank is a
full service financial organization serving customers throughout North America
and managing assets in excess of $150 billion. The bank has over 1,000
branches/offices and utilizes over 8,000 workstations and servers. The bank
chose HARBOR as its backup product because HARBOR meets its multi-site, data
integrity and high security needs.
 
  A major European bank, with numerous worldwide subsidiaries, is using HARBOR
Backup in their decentralized back-up system project. This customer sought
host-initiated, unattended over-night backup, and user-oriented and helpdesk-
supported restore in the case of emergency. The first phase of the project
covers backup and restore of approximately 700 OS/2 servers. Functionality,
security and support were the crucial factors in the bank's decision to choose
HARBOR. The bank plans to extend the project to an additional 500 OS/2
software development servers. In addition, in the first quarter 1996, the
decision was made to use HARBOR Distribution as the solution for software
distribution and management for their electronic software distribution
project.

TECHNOLOGY
 
  The Company's core technologies are the basis for its enterprise networked
systems management products. These technologies allow for the expansion of
existing products and addition of new products to the Company's systems
management architecture.
 
 Network Transport Products
 
  The TCPaccess product line, the Company's principal network transport
products, was developed within an application architecture consisting of key
components which provide high-performance, efficient operation, rapid
development, reusable code and improved maintainability. These key components
are: (i) TCP/IP Base; (ii) TCP/IP APIs; (iii) TCP/IP Applications; and (iv)
IFS Architecture.
 
  TCP/IP Base. The TCP/IP base technology incorporates a high speed, efficient
transport protocol implementation which allows client/server applications to
communicate using TCP/IP. This software product is a multi-layered
communications module with two basic functions: (i) communicating via drivers
with the LAN controller devices to provide physical network connectivity; and
(ii) implementing protocols to establish interoperability between TCP/IP
environments and the enterprise server. Included within the base technology
are fault tolerant features enabled when the customer purchases TCPaccess
Fault Tolerant. This fault tolerant technology allows TCP/IP to recover
automatically from hardware problems in the network to preserve the sessions
between the enterprise server and remote TCP/IP systems. All portions of
TCPaccess critical to high performance and efficient operation are written in
assembler language. The base technology was architected and implemented
natively in MVS for the enterprise server environment. Use of technology
porting was minimized to ensure optimum performance and efficiency. The
technology is developed in accordance with Requests for Comments governed by
the Internet Engineering Task Force, and the Company's personnel participate
in the standards development process for key TCP/IP standards.
 
  TCP/IP Application Programming Interfaces. TCPaccess contains an API layer
to allow independent software vendors ("ISVs") and the Company's customers to
use the TCP/IP technology to develop client/server applications. A variety of
industry standard APIs are provided, including BSD sockets, X/Open Transport
Interface and Sun/ONC RPC/XDR. All of the APIs in TCPaccess were architected
and designed specifically for the enterprise server environment to deliver
high performance and efficient operation for ISV and customer applications.
 
  TCP/IP Applications. Certain TCP/IP applications such as file transfer
protocol and tn3270 terminal access are implemented in the same address space
as the TCP/IP base technology. This architecture, in which key servers are in
the same address space, enhances the performance and efficiency of these
important services. The TCP/IP base and application services are implemented
as threads within a multi-threaded environment provided as part of the base
connectivity technology. The use of threading technology provides scalability
and permits large numbers and applications to be supported in TCPaccess.
 
  IFS Architecture. IFS Architecture ("IFS") is proprietary enterprise server
software that provides for rapid development of systems management
applications within the enterprise server environment. TCPaccess is an IFS
application. Components of TCPaccess execute within IFS as separate processes
(e.g., TCP/IP protocol stack, API, domain name resolver, SNMP agent and
others). IFS is written in assembler language for high performance and low CPU
resource usage. Applications developed in IFS can span threads, processes and
address spaces, providing location transparency to developers to simplify and
speed the development of software. IFS also provides common system-level
services for IFS application developers. IFS significantly reduces the time
required to create new TCPaccess applications.

 Systems Management Applications
 
  The HARBOR products, the Company's principal systems management
applications, were developed within an application architecture consisting of
key components which provide high-performance, efficient operation, rapid
development, reusable code, portable code and improved maintainability. These
key components are: (i) HARBOR Transport Services; (ii) HARBOR Transport
Gateway; (iii) HARBOR Multi-System Platform; (iv) HARBOR Policy Database; and
(v) HARBOR Client User Interface.
 
  HARBOR Transport Services. The HARBOR Transport Services is proprietary
networking middleware software that connects a large variety of clients,
servers, and networks in a customer's distributed system. HARBOR Backup,
HARBOR Distribution, HARBOR Transport Gateway and HARBOR Distributed Storage
Server all make use of HARBOR Transport Services. The technology enables
HARBOR developers to use one programming interface for network access,
regardless of the underlying transport protocol, shielding them from the
issues and difficulties that can be encountered in programming to individual
network transport protocol interfaces. HARBOR Transport Services can
automatically recover from network failures, including retrying operations
over an alternate protocol, transparently to the application. This single
networking API, and other APIs within HARBOR Transport Services, are key to
being able to develop portable networked systems management applications on a
variety of common client/server platforms.
 
  HARBOR Transport Gateway. The HARBOR Transport Gateway is an application
built upon the HARBOR Transport Services which connects a large variety of
clients, servers and networks in a customer's distributed system. This
technology provides transparent conversion between LAN/WAN transport protocols
including TCP/IP, APPC, 3270, IPX/SPX, Asynch and others. The HARBOR Transport
Gateway permits a customer to utilize two or more dissimilar network transport
protocols in their environment, with the gateway performing the mapping of
HARBOR application data streams from one transport to another.
 
  HARBOR Multi-System Platform. The HARBOR Multi-System Platform ("MSP") is
proprietary enterprise server software that permits rapid development of
applications within the HARBOR environment. The HARBOR Backup and HARBOR
Distribution products are MSP applications. Applications developed in MSP can
span threads, processes, address spaces and machines, providing location
transparency to developers to simplify and speed development of software. The
support within MSP for threading is a key to providing scalability,
performance and efficiency for HARBOR applications. MSP also provides common
system-level services for HARBOR software developers.
 
  HARBOR Policy Database. The HARBOR Policy Database is a proprietary database
and an administrative facility that controls all HARBOR management functions,
and improves user and system administrator productivity. It provides a single
location for defining and managing security access, administrative policies
and distribution schedules for HARBOR Backup and HARBOR Distribution. The
database is hierarchical in nature allowing rules to be defined at a high
level as defaults and then augmented by different levels of administration.
The technology is integrated with standard security management interfaces such
as RACF, CA-Top Secret and CA-ACF2.
 
  HARBOR Client User Interface. The HARBOR Client User Interface is the
graphical user interface presented to both HARBOR Backup and HARBOR
Distribution client users. Technology for the development of graphical user
interfaces provided by a third party enables the Company to develop HARBOR
user interfaces rapidly, with a high degree of portability and with a
consistent "look and feel" across platforms.
 
PRODUCT DEVELOPMENT
 
  The Company has made substantial investments in research and development to
produce high-performance network transport products and systems management
applications. As of March 31, 1996, the Company's research and development and
quality assurance organization consisted of 49 employees. The Company intends
to enhance its existing product offerings and to introduce additional products
for the enterprise networked
 
                                      40
<PAGE>
 
systems management market. The Company uses standard product development
methodologies in the design and development of its products to ensure
efficiency in development and high product quality. In addition, the Company
solicits input from its customers to gain insight into their specific network
requirements, enabling the research and development staff to enhance existing
products and create new products to suit the market. The Company designs its
products to be portable and adaptable to new client/server hardware and
software environments. The Company uses software development tools such as
configuration management, code testing, and performance monitoring to aid in
this development. The Company outsources its host computing resource
requirements for cost effectiveness and efficiency. To date, most of the
Company's core technologies for its network transport products and systems
management applications have been acquired and have not been developed
internally. While the Company expects that certain of its new products will be
developed internally, the Company may also, based on timing and cost
considerations, acquire technology and products.
 
  The Company is currently completing the development of TCPaccess Version
4.1, which is expected to be released late 1996 and is intended to support
open edition MVS-API. The Company intends to develop additional versions to
provide compatibility with IBM APIs and certain IBM user-level applications.
The Company is also developing enhancements to the HARBOR products, including
a version of HARBOR to support Windows NT on platforms other than the Intel-
based NT platform currently supported. The Company expects to also add Netware
remote administration with a graphical user interface for Windows 95. The
Company intends to develop HARBOR Agent for Networker (Legato's client/server
storage management solution) which will provide HARBOR functionality to
client/server storage management products sold by Legato. There can be no
assurance that the Company's new or enhanced products will be timely
developed, or at all, and even if developed, that such products will achieve
market acceptance.
 
COMPETITION
 
  General. The market in which the Company operates is intensely competitive
and is characterized by extreme price competition and rapid technological
change. The competitive factors influencing the markets for the Company's
products include product performance, price, reliability, features,
scalability, interoperability across multiple platforms, adherence to industry
standards, and the provision of support and maintenance services. The Company
competes with a number of companies, principally IBM, that specialize in one
or more of the Company's product lines, and such competitors may have greater
financial, technical, sales and marketing resources to devote to the
development, promotion and sale of their products, and may have longer
operating histories, greater name recognition, and greater market acceptance
for their products and services compared to those of the Company. There can be
no assurance that the Company's current competitors or any new market entrants
will not develop networked systems management products or other technologies
that offer significant performance, price or other advantages over the
Company's technologies, the occurrence of which would have a material adverse
effect on the Company's business, financial condition and results of
operations.
 
  Network Transport Products. The Company sells its TCPaccess suite of
products principally to customers who have installed IBM mainframes using the
MVS operating system. The Company's main competition for its TCPaccess
products is IBM. IBM sells TCP/IP and associated products for its MVS
mainframe systems that compete directly with the Company's TCPaccess product
line. In addition, IBM recently released its OS/390 operating system, which
includes TCP/IP communications software in a bundle of software provided to
purchasers of OS/390. An IBM customer can request to have the IBM TCP/IP
product removed from the software bundle provided by IBM and thereby reduce
the purchase price of the system purchased. The reduction in the purchase
price related to the exclusion of IBM's TCP/IP for MVS product from its
software bundle, in certain model groups, is substantially smaller than the
price the customer would have to pay to purchase the Company's corresponding
TCPaccess product. Because in some IBM model groups IBM's TCP/IP product is
less expensive to purchase than the Company's corresponding TCPaccess products
in the same model groups, there could be substantial erosion of the Company's
margins if the Company reduces the price of its TCPaccess products in order to
compete against IBM, which erosion would have a material adverse effect on the
Company's business, financial condition and results of operations. Also, IBM
could in the future decide to include
 
                                      41
<PAGE>
 
its TCP/IP product in the bundle of software provided to purchasers of its
OS/390 operating system without charge. The Company believes that any
reduction in price of the IBM TCP/IP products, or the bundling of those
products without charge in its OS/390 operating system, would require the
Company to either reduce the prices of its TCPaccess products or substantially
increase sales and marketing expenses, or both, in order to continue to sell
its TCPaccess products, which actions would have a material adverse effect on
the Company's business, financial condition and results of operations. In
addition, if IBM were to develop or design its OS/390 operating system or
other products so that its TCP/IP product cannot be removed, customers who
otherwise would have been inclined to purchase the Company's TCPaccess product
may not do so, which would have a material adverse effect on the Company's
business, financial condition and results of operations. In addition, the
Company derives a substantial portion of its revenues from maintenance
agreements with its TCPaccess customers. If the Company sells fewer TCPaccess
products, either due to competition from IBM or otherwise, the Company's
maintenance revenues would be reduced, which would have a material adverse
effect on the Company's business, financial condition and results of
operations. If IBM reduces the combined price of its TCP/IP products and
maintenance, IBM's combined price for its TCP/IP products and maintenance
would be more price competitive with the Company's product line, and the
Company's product and maintenance revenues would be adversely affected. The
Company also competes with IBM, Apertus, Cisco Systems, Inc., Computerm,
Network Solutions, Inc. and Memorex in the network controller market, where
the Company resells the network controller of Bus-Tech to provide the hardware
connection which links the enterprise server to the client/server network.
 
  System Management Applications. The primary competitors for the Company's
HARBOR Backup product are IBM, Storage Technology, Innovation Data Processing,
Inc. and Boole & Babbage, Inc. The Company's competition for the HARBOR
Distribution Manager are IBM, Novadigm, Inc. and Tangram Enterprise Solutions,
Inc. IBM is aggressively marketing its ADSM backup product, which is included
in the System View package on IBM's UNIX system, AIX. There can be no
assurance that IBM will not include the ADSM backup products in a software
"bundle" with the sale of its mainframe hardware systems. The bundling of
competing software products with mainframe hardware systems could have a
material adverse effect on the Company's business, financial condition and
results of operations. The Company also competes with software vendors who
develop and market products for UNIX and Windows NT operating systems, such as
Microsoft, Arcada Software, Inc., Cheyenne Software, Inc., Computer
Associates, Inc., EMC Corporation, Hewlett-Packard Company, Legato, Novadigm,
Inc., OpenVision Technology, Inc., PLATINUM technology, inc., Sterling
Software, Inc., Sun Microsystems, Inc. and Unison Software, Inc., which are
focusing on enterprise systems management applications. Although the Company
recently signed a strategic marketing agreement with Legato, the Company is
still a competitor of Legato in the storage management market. The Company
also expects increased competition from vendors of TCP/IP-to-SNA gateway
products, including such companies as Microsoft, Novell, Inc., Apertus and
CNT/Brixton Systems, Inc. Competition from these companies could increase due
to an expansion of their product lines or a change in their approach to
enterprise systems management or networking products. The bundling of network
transport software with a network controller by these competitors could
prevent the Company from selling TCPaccess to the customers of these
competitors, which would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
  Other Factors. The Company's ability to compete successfully depends on many
factors, including the Company's success in developing new products that
implement new technologies, performance, price, product quality, reliability,
success of competitors' products, general economic conditions, and protection
of Interlink products by effective utilization of intellectual property laws.
In particular, competitive pressures from existing or new competitors who
offer lower prices or other incentives or introduce new products could result
in price reductions which would adversely affect the Company's profitability.
There can be no assurance that the Company's current or other new competitors
will not develop enhancements to, or future generations of, competitive
products that offer superior price or performance features, that the Company
will be able to compete successfully in the future, or that the Company will
not be required to incur substantial additional investment costs in connection
with its engineering, research, development, marketing and customer service
efforts in order to meet any competitive threat. The Company expects
competition to intensify, and increased competitive
 
                                      42
<PAGE>
 
pressure could cause the Company to lower prices for its products, or result
in reduced profit margins or loss of market share, any of which could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
  The Company's success and ability to compete is dependent in part upon its
proprietary information. The Company relies primarily on a combination of
copyright and trademark laws, trade secrets, software security measures,
license agreements and nondisclosure agreements to protect its proprietary
technology and software products. There can be no assurance, however, that
such protection will be adequate to deter misappropriation, deter unauthorized
third parties from copying aspects of, or otherwise obtaining and using, the
Company's software products and technology without authorization, or that the
rights secured thereby will provide competitive advantages to the Company. In
addition, the Company cannot be certain that others will not develop
substantially equivalent or superseding proprietary technology, or that
equivalent products will not be marketed in competition with the Company's
products, thereby substantially reducing the value of the Company's
proprietary rights. Furthermore, there can be no assurance that any
confidentiality agreements between the Company and its employees or any
license agreements with its customers will provide meaningful protection for
the Company's proprietary information in the event of any unauthorized use or
disclosure of such proprietary information.
 
  There can be no assurance that others will not independently develop similar
products or duplicate the Company's products. 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. There can be no assurance that the steps taken
by the Company to protect its proprietary technology will prevent
misappropriation of such technology, and such protections may not preclude
competitors from developing products with functionality or features similar to
or superior to the Company's products. A substantial amount of the Company's
sales are in international markets, and the laws of other countries may afford
the Company little or no effective protection of its intellectual property.
 
  While the Company believes that its products and trademarks do not infringe
upon the proprietary rights of third parties, there can be no assurance that
the Company will not receive future communications from third parties
asserting that the Company's products infringe, or may infringe, the
proprietary rights of third parties. The Company expects that software product
developers will be increasingly 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 and diversion of technical and management personnel, cause product
shipment delays or require the Company to develop non-infringing technology or
enter into royalty or licensing agreements, any of which could have a material
adverse effect on the Company's business, financial condition and results of
operations. Such royalty or licensing agreements, if required, may not be
available on terms acceptable to the Company or at all. In the event of a
successful claim of product infringement against the Company and failure or
inability of the Company to develop non-infringing technology or license the
infringed or similar technology, the Company's business, financial condition
and results of operations could be materially adversely affected. In addition,
the Company may initiate claims or litigation against third parties for
infringement of the Company's proprietary rights or to establish the validity
of the Company's proprietary rights. Any such claims could be time consuming,
result in costly litigation, or lead the Company to enter into royalty or
licensing agreements rather than litigating such claims on their merits.
Moreover, an adverse outcome in litigation or similar adversarial proceedings
could subject the Company to significant liabilities to third parties, require
expenditure of significant resources to develop non-infringing technology,
require disputed rights to be licensed from others or require the Company to
cease the marketing or use of certain products, any of which could have a
material adverse effect on the Company's business, financial condition and
results of operations.

EMPLOYEES
 
  As of March 31, 1996, the Company and its subsidiaries employed a total of
158 persons, of which 63 are in sales and marketing, 49 are in research and
development and quality assurance, 23 are in customer support and 23 are in
finance and administration. Interlink employs 85 persons in the United States,
36 persons in Canada, and 37 persons in Europe. The Company's continued
success will depend on its ability to attract and retain key employees. No
employees are represented by a labor union, and the Company considers its
employee relations to be good.
 
FACILITIES
 
  The Company is headquartered in a 24,000 square foot facility in Fremont,
California. The Fremont facility houses the corporate functions, marketing,
research and development, customer support and finance and administration.
Interlink occupies this space under a lease agreement that expires on December
31, 2000. The Company has a research and development center in Columbia,
Maryland where the TCPaccess product line is developed, and in Calgary,
Alberta, Canada where the HARBOR products are developed and supported. The
Company leases office space in ten locations in the United States and Europe
for use by its regional sales and support staff. The Company believes that its
facilities are adequate to meet its requirements through the expiration of its
leases.
 
LEGAL DISPUTE
 
  The Company and the Company's subsidiary in France are involved in a
commercial dispute with Selesta, a former Italian distributor of the Company's
TCPaccess products. Selesta alleged in a letter sent to the Company that the
Company had breached and unlawfully terminated the agreement pursuant to which
Selesta was appointed a distributor of the Company's products in Italy and
asserted other related claims against the Company. The letter demanded
Selesta's reinstatement as a distributor, the execution of a written
distribution agreement setting forth the distribution arrangements between the
parties, and compensation in an unspecified amount to be paid to Selesta for
the harm that it has suffered. The Company's Canadian subsidiary, New Era, has
also used Selesta as a distributor of the HARBOR products in Italy pursuant to
a separate agreement and may or may not continue to do so in the future. No
legal claim has been filed nor has arbitration been invoked by Selesta
regarding this matter. Should Selesta initiate legal proceedings and prevail
on such claims, the Company's business, financial condition and results of
operations could be materially adversely affected. See "Risk Factors--Legal
Dispute."

mechanism. On the effective date of the Director Plan or when the director
becomes an outside director, each of the non-employee directors will
automatically be granted an option to purchase 10,000 shares of the Company's
Common Stock at an exercise price equal to the initial public offering price.
In addition, upon joining the Board of Directors, each new non-employee
director will automatically be granted an option to purchase 10,000 shares of
Common Stock and each non-employee director will subsequently be granted an
additional option to purchase 2,500 shares of Common Stock, each such option
to be granted at the fair market value of the Common Stock on the date of
grant. In addition, the Company reimburses the reasonable travel expenses of
the directors. See "--Stock Plans--Director Option Plan."

(1) This column shows the hypothetical gains or "option spreads" of the
    options granted based on assumed annual compound stock appreciation rates
    of 5% and 10% over the full seven-year term of the options. The 5% and 10%
    assumed rates of appreciation are mandated by the rules of the Securities
    and Exchange Commission and do not represent the Company's estimate or
    projection of future Common Stock prices. The gains shown are net of the
    option exercise price, but do not include deductions for taxes or other
    expenses associated with the exercise of the option or the sale of the
    underlying shares. The actual gains, if any, on the exercises of stock
    options will depend on the future performance of the Common Stock, the
    option holder's continued employment through the option period, and the
    date on which the options are exercised.
 
(2) Options vest as to 9/48th of the option shares after nine months from the
    vesting commencement date and as to 1/48th of the option shares each month
    thereafter, with full vesting occurring on the fourth anniversary of the
    vesting commencement date. The Board of Directors determined the market
    value of the Common Stock based on various factors, including the illiquid
    nature of an investment in the Common Stock, the Company's historical
    financial performance, the preferences (including liquidation) of the
    outstanding Series 1 Preferred Stock, the Company's future prospects and
    the prices paid for securities of the Company in arm's length transactions
    between third parties.
 
(3) 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 on
    the date of grant. Exercise price may be paid in cash, promissory note, by
    delivery of already-owned shares subject to certain conditions, or
    pursuant to a cashless exercise procedure under which the optionee
    provides irrevocable instructions to a brokerage firm to sell the
    purchased shares and to remit to the Company, out of the sale proceeds, an
    amount equal to the exercise price plus all applicable withholding taxes.

(1) There was no public trading market for the Common Stock as of June 30,
    1995. Accordingly, these values have been calculated on the basis of an
    assumed initial public offering of $10.00 per share, less the applicable
    option exercise price.
 
STOCK PLANS
 
  1992 Stock Option Plan. The Company's 1992 Stock Option Plan (as amended,
the "1992 Plan") was adopted by the Board of Directors in June 1992, approved
by the Company's stockholders in July 1992 and amended in June 1996. In June
1996, the Company increased the number of shares of Common Stock reserved
under the 1992 Plan by 1,700,000 shares to 3,910,000 shares. The 1992 Plan
provides for grants of incentive stock options, restricted stock and stock
purchase rights to employees (including officers and employee directors) and
nonstatutory stock options to employees (including officers and employee
directors) and consultants of the Company. The purpose of the 1992 Plan is to
attract and retain the best available personnel to the Company and to
encourage stock ownership by employees, officers and consultants of the
Company to give them a greater personal stake in the success of the Company.
The 1992 Plan is presently being administered by the Board of Directors, which
determines optionees and the terms of options granted, including the exercise
price, number of shares subject to the option and the exercisability thereof.
 
  The terms of options granted under the Option Plan generally may not exceed
ten years. However, the term of all incentive stock options and nonstatutory
stock options granted to an optionee who, at the time of grant, owns stock
representing more than 10% of the Company's outstanding capital stock, may not
exceed five years. The vesting of all stock option grants is determined by the
Board of Directors. Generally options granted under the 1992 Plan vest and
become exercisable starting nine months after the date of grant, with 9/48th
of the shares subject to option becoming exercisable at that time and an
additional 1/48th of such shares subject to the option becoming exercisable
each month thereafter. No option may be transferred by the optionee other than
by will or the laws of descent or distribution, and each option may be
exercised, during the lifetime of the optionee, only by such optionee. An
optionee whose relationship with the Company or any related corporation ceases
for any reason (other than by death or permanent and total disability) may
exercise options in the 30-day period following such cessation (unless such
options terminate or expire sooner by their terms) or in such longer period as
is determined by the Board of Directors. In the event of a merger of the
Company with or into another corporation, all outstanding options may either
be assumed or an equivalent option may be substituted by the surviving entity
or, if such options are not assumed or substituted, such options shall
terminate as of the date of closing of the merger. The exercise price of
incentive stock options granted under the 1992 Plan must be at least equal to
the fair market value of the shares on the date of grant. The exercise price
of nonstatutory stock options granted under the 1992 Plan is determined by the
administrator. With respect to any participant who owns stock possessing more
than 10% of the voting rights of the Company's outstanding capital stock, the
exercise price of any incentive stock option or any nonstatutory stock option
granted must equal at least 110% of the fair market value on the grant date.
The consideration for exercising any incentive stock option or any
nonstatutory stock option may consist of cash, check, promissory note,
delivery of already-owned shares of the Company's Common Stock subject to
certain conditions, delivery of a properly executed exercise notice together
with irrevocable instructions to a broker to promptly deliver to the Company
the amount of sale or loan proceeds
 
                                      49
<PAGE>
 
required to pay the exercise price, a reduction in the amount of any Company
liability to an optionee, or any combination of the foregoing methods of
payment or such other consideration or method of payment to the extent
permitted under applicable law. No incentive stock options may be granted to a
participant, which, when aggregated with all other incentive stock options
granted to such participant, would have an aggregate fair market value in
excess of $100,000 becoming exercisable in any calendar year.
 
  As of March 31, 1996, 120,374 shares of Common Stock had been issued upon
the exercise of options granted under the 1992 Plan, options to purchase
2,015,455 shares of Common Stock at a weighted average exercise price of $0.55
share were outstanding and 74,171 shares remained available for future option
grants. The 1992 Plan will terminate in June 2002, unless sooner terminated by
the Board of Directors.
 
  Employee Stock Purchase Plan. The Company's 1996 Employee Stock Purchase
Plan (the "Purchase Plan") was adopted by the Board of Directors and approved
by the stockholders in June 1996. A total of 500,000 shares of Common Stock
has been reserved for issuance under the Purchase Plan. The Purchase Plan,
which is intended to qualify under Section 423 of the Internal Revenue Code of
1986, as amended, is administered by the Board of Directors or by a committee
appointed by the Board. Employees (including officers and employee directors
of the Company) are eligible to participate if they are customarily employed
for at least 20 hours per week and for more than five months in any calendar
year. The Purchase Plan permits eligible employees to purchase Common Stock
through payroll deductions, which may not exceed 15% of an employee's
compensation; provided that a participant may not purchase more than $12,500
worth of shares of the Company's Common Stock during each purchase period. The
Purchase Plan will be implemented in a series of overlapping purchase periods,
each to be of approximately six months duration. The initial purchase period
under the Purchase Plan will begin on the effective date of this offering and
subsequent purchase periods will begin on the first trading day on or after
November 1 and May 1 of each year. Each participant will be granted an option
on the first day of the purchase period and such option will be automatically
exercised on the last date of each semi-annual period throughout the purchase
period. If the fair market value of the Common Stock on any purchase date is
lower than such fair market value on the start date of that purchase period,
then all participants in that purchase period will be automatically withdrawn
from such purchase period and reenrolled in the immediately following purchase
period. The purchase price of the Common Stock under the Purchase Plan will be
equal to 85% of the lesser of the fair market value per share of Common Stock
on the start date of the purchase period or on the date on which the option is
exercised. Employees may end their participation in a purchase period at any
time during that period, and participation ends automatically on termination
of employment with the Company. The Purchase Plan will terminate in June 2006,
unless sooner terminated by the Board of Directors.
 
  Director Option Plan. The Company's 1996 Director Option Plan (the "Director
Plan") was adopted by the Board of Directors and approved by the stockholders
of the Company in June 1996. A total of 100,000 shares of Common Stock are
reserved for issuance under the Director Plan. The option grants under the
Director Plan are automatic and non-discretionary, and the exercise price of
the options is 100% of the fair market value of the Common Stock on the grant
date. The Director Plan provides for an initial grant of options to purchase
10,000 shares of Common Stock to each non-employee director of the Company (an
"Outside Director") upon the later of the effective date of the Director Plan
or when the director becomes an outside director after the effective date of
this offering. Each new non-employee director will automatically be granted an
option to purchase 10,000 shares of Common Stock upon joining the Board of
Directors. Subsequently, each Outside Director will automatically be granted
an additional option to purchase 2,500 shares of Common Stock at the next
meeting of the Board of Directors following the annual meeting of stockholders
in each year beginning with the 1997 annual meeting of stockholders, if on
such date, such Outside Director has served on the Board of Directors for at
least six months. The term of such options is ten years. The initial option
grant of 10,000 shares to an Outside Director shall vest at a rate of 1/48th
of the shares per month following the date of grant and the subsequent option
grant of 2,500 shares shall vest at the end of four year. The Director Plan
will terminate in June 2006, unless sooner terminated by the Board of
Directors.

401(K) PLAN
 
  Effective in September 1990, the Company adopted the 401(k) Profit Sharing
Plan (the "401(k) Plan") that covers all eligible employees of the Company. An
eligible employee may elect to defer, in the form of contributions to the
401(k) Plan, up to 15% of the total compensation that would otherwise be paid
to the employee, not to exceed approximately $9,500 per year (adjusted for
cost-of-living increases). Employee contributions are invested in selected
equity mutual funds, a guaranteed interest contract account or a money market
fund according to the directions of the employees. The contributions are fully
vested and nonforfeitable at all times. The 401(k) Plan provides for employer
contributions as determined by the Board of Directors. The Company has not
made any contributions through fiscal 1996.
 
EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS
 
  Messrs. Jepson, Gammon, Berkeley, Ms. Purdy and Ms. Booth each have entered
into letter agreements with the Company which provide for severance payments
if they are terminated without cause. Messrs. Jepson, Gammon and Ms. Purdy
will be entitled to severance payments equal to six months salary, and Mr.
Berkeley and Ms. Booth will be entitled to severance payments equal to three
months salary. All of the Named Executive Officers' employment with the
Company is terminable at will.
 
  In connection with an acquisition of the Company by merger or asset sale,
each outstanding option held by the Named Executive Officers under the 1992
Stock Option Plan will automatically accelerate in full and all unvested
shares of Common Stock held by such individuals subject to direct issuances
made under the 1992 Stock Option Plan will immediately vest in full, except to
the extent such options are to be assumed by, and the Company's repurchase
rights with respect to these shares are to be assigned to, the successor
corporation.
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS
 
  The Company has adopted provisions in its Certificate of Incorporation that
eliminate to the fullest extent permissible under Delaware law the liability
of its directors to the Company for monetary damages. Such limitation of
liability does not affect the availability of equitable remedies such as
injunctive relief or rescission. The Company's Bylaws provide that the Company
shall indemnify its directors and officers to the fullest extent permitted by
Delaware law, including in circumstances in which indemnification is otherwise
discretionary under Delaware law. The Company has entered into indemnification
agreements with its officers and directors containing provisions which may
require the Company, among other things, to indemnify the 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), and to advance their expenses
incurred as a result of any proceeding against them as to which they could be
indemnified.
 
  At the present time, there is no pending litigation or proceeding involving
a director, officer, employee or other agent of the Company in which
indemnification would be required or permitted. The Company is not aware of
any threatened litigation or proceeding which may result in a claim for such
indemnification.

                             CERTAIN TRANSACTIONS
 
  On December 29, 1995, the Company acquired New Era ("New Era Acquisition").
In connection with the New Era Acquisition, the Company, through a wholly-
owned Canadian acquisition subsidiary, acquired the outstanding New Era Common
Stock, Class B Preferred Stock and outstanding options. Immediately prior to
the closing of the New Era Acquisition, Mr. Dulley beneficially controlled
26,616 shares of New Era Common Stock and an option to acquire 8,230 shares of
New Era Common Stock. At the closing of the New Era Acquisition, Mr. Dulley
and his relatives collectively received $1,700,387 from the Company as
consideration for their New Era Common Stock. Pursuant to the New Era
Acquisition, Mr. Dulley and his relatives received warrants to purchase an
aggregate of 81,440 shares of the Company's Common Stock.
 
  In January and March 1994, the Company sold 2,459,424 shares of Series 1
Preferred Stock to certain individuals and entities in a private placement
transaction at $2.75 per share. The holders of the Series 1 Preferred Stock
are entitled to certain registration rights. See "Descriptions of Capital
Stock--Registration Rights." The purchasers of the Series 1 Preferred Stock
included, among others, the following entities affiliated with directors and
underwriters of the Company's proposed initial public offering:

                         DESCRIPTION OF CAPITAL STOCK
 
  Upon the completion of this offering, the authorized capital stock of the
Company will consist of 25,000,000 shares of Common Stock, $0.001 par value,
and 5,000,000 shares of undesignated Preferred Stock, $0.001 par value.
 
COMMON STOCK
 
  As of March 31, 1996, there were 4,954,575 shares of Common Stock
outstanding held of record by approximately 237 stockholders. As of March 31,
1996, options to purchase an aggregate of 2,015,455 shares of Common Stock
were also outstanding. See "Management--Stock Plans."
 
  The holders of Common Stock are entitled to one vote per share on all
matters to be voted on by stockholders and have cumulative voting rights with
respect to the election of directors. The holders of Common Stock are entitled
to receive such dividends, if any, as may be declared from time to time by the
Board of Directors in its discretion from funds legally available therefor.
Upon liquidation or dissolution of the Company, the remainder of the assets of
the Company will be distributed ratably among the holders of Common Stock. The
Common Stock has no preemptive or other subscription rights and there are no
conversion rights or redemption or sinking fund provisions with respect to
such shares. All of the outstanding shares of Common Stock are, and the shares
to be sold in this offering will be, fully paid and nonassessable.
 
WARRANTS
 
  As of March 31, 1996, there were outstanding warrants to purchase an
aggregate of 133,334 shares of Common Stock at an exercise price of $.45 per
share, which expire December 1998, 150,000 shares of Common Stock at an
exercise price of $.45 per share, which expire January 1999, an aggregate of
700,000 shares of Common Stock at an exercise price of $1.60 per share, which
expire December 2000, an aggregate of 162,500 shares of Preferred Stock at an
exercise price of $1.60 per share, which expire April 2003 (which will be
reduced to 125,000 upon the closing of this offering), and an aggregate of
30,000 shares of Preferred Stock at an exercise price of $2.75 per share,
which expire December 1998.
 
PREFERRED STOCK
 
  Effective upon the closing of this offering, the Company will be authorized
to issue 5,000,000 shares of undesignated Preferred Stock. The Board of
Directors has the authority to issue the Preferred Stock in one or more series
and to fix the price, rights, preferences, privileges and restrictions
thereof, including dividend rights, dividend rates, conversion rights, voting
rights, terms of redemption, redemption prices, liquidation preferences and
the number of shares constituting a series or the designation of such series,
without any further vote or action by the Company's stockholders. The issuance
of Preferred Stock, while providing desirable flexibility in connection with
possible acquisitions and other corporate purposes, could have the effect of
delaying, deferring or preventing a change in control of the Company without
further action by the stockholders and may adversely affect the market price
of, and the voting and other rights of, the holders of Common Stock. The
Company has no current plans to issue any shares of Preferred Stock.
 
REGISTRATION RIGHTS
 
  Following the closing of this offering, the holders of approximately
6,119,936 issued or issuable shares of Common Stock (the "Registrable
Securities"), of which 988,334 are issuable upon exercise of warrants, will be
entitled to certain rights with respect to the registration of such shares of
Common Stock under the Securities Act. Under an agreement among the Company
and holders of Registrable Securities, if the Company proposed to register any
of its Common Stock under the Securities Act, certain holders of Registrable
Securities are entitled to notice of such registration and to include their
Registrable Securities therein; provided, among other conditions, that the
underwriters have the right to limit the number of shares included in any such
registration.
 
                                      55
<PAGE>
 
Beginning 180 days after the closing of this offering, the holders of at least
twenty-five percent (25%) of the Registrable Securities have the right to
require the Company, on not more than two occasions, to file a registration
statement under the Securities Act in order to register all or any part of
their Registrable Securities. The Company may, in certain circumstances, defer
such registration and the underwriters have the right, subject to certain
limitations, to limit the number of shares included in such registrations.
Further, the holders of Registrable Securities may require the Company to
register all or any portion of their Registrable Securities on Form S-3, when
such form becomes available to the Company, subject to certain conditions and
limitations.
 
CHANGE OF CONTROL PROVISIONS
 
  Certain provisions of the Company's Certificate of Incorporation and Bylaws
may have the effect of preventing, discouraging or delaying a change in the
control of the Company and may maintain the incumbency of the Board of
Directors and management. The authorization of undesignated Preferred Stock
makes it possible for the Board of Directors to issue Preferred Stock with
voting or other rights or preferences that could impede the success of any
attempt to change control of the Company. In addition, the Company's Bylaws
limit the ability of stockholders of the Company to raise matters at a meeting
of stockholders without giving advance notice.
 
CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BYLAWS
 
  Certain provisions of the Company's Certificate of Incorporation and Bylaws
may have the effect of preventing, discouraging or delaying a change in the
control of the Company and may maintain the incumbency of the Board of
Directors and management. The authorization of undesignated Preferred Stock
makes it possible for the Board of Directors to issue Preferred Stock with
voting or other rights or preferences that could impede the success of any
attempt to change control of the Company. In addition, the Company's Bylaws
limit the ability of stockholders of the Company to raise matters at a meeting
of stockholders without giving advance notice.
 
  The Certificate of Incorporation provides that stockholder action can be
taken only at an annual or special meeting of stockholders and cannot be taken
by written consent in lieu of a meeting. The Certificate of Incorporation and
the Bylaws provide that, except as otherwise required by law, special meetings
of the stockholders can only be called pursuant to a resolution adopted by a
majority of the Board of Directors, by the Chief Executive Officer of the
Company, or by stockholders holding shares in the aggregate entitled to cast
not less than 10% of the votes at that meeting.
 
  The Bylaws establish an advance notice procedure for stockholder proposal to
be brought before an annual meeting of stockholders of the Company, including
proposed nominations of persons for election to the Board. Stockholders at an
annual meeting may only consider proposals or nominations specified in the
notice of meeting or brought before the meeting by or at the direction of the
Board or by a stockholder who was a stockholder of record on the record date
for the meeting, who is entitled to vote at the meeting and who has given to
the Company's Secretary timely written notice, in proper form, of the
stockholder's intention to bring that business before the meeting. Although
the Bylaws do not give the Board the power to approve or disapprove
stockholder nominations of candidates or proposals regarding other business to
be conducted at a special or annual meeting, the Bylaws may have the effect of
precluding the conduct of certain business at a meeting if the proper
procedures are not followed or may discourage or defer a potential acquiror
from conducting a solicitation of proxies to elect its own slate of directors
or otherwise attempting to obtain control of the Company.
 
  The Certificate of Incorporation provides that the affirmative vote of
holders of at least 66 2/3% of the total votes eligible to participate in the
election of directors is required to amend, alter, change or repeal certain of
their provisions. This requirement of a supermajority vote to approve
amendments to the Certificate of Incorporation and Bylaws could enable a
minority of the Company's stockholders to exercise veto power over any such
amendments.

CERTAIN PROVISIONS OF DELAWARE LAW
 
  Following the consummation of the offering, the Company will be subject to
the "Business Combination" provisions of the Delaware General Corporation Law.
In general, such provisions prohibit a publicly held Delaware corporation from
engaging in various "business combination" transactions with any "interested
stockholder" for a period of three years after the date of the transaction
which the person became an "interested stockholder," unless (i) the
transaction is approved by the Board of Directors prior to the date the
interested stockholder obtained such status, (ii) upon consummation of the
transaction which 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 by (a) persons who are directors and also officers and (b)
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 by the affirmative
vote of at least 66 2/3% of the outstanding voting stock which is not owned by
the "interested stockholder." A "business combination" is defined to include
mergers, asset sales and other transactions resulting in a financial benefit
to a stockholder. In general, an "interested stockholder" is a person who,
together with affiliates and associates, owns (or within three years, did own)
15% or more of a corporation's voting stock. The statute could prohibit or
delay mergers or other takeover or change in control attempts with respect to
the Company and, accordingly, may discourage attempts to acquire the Company.
 
TRANSFER AGENT
 
  The transfer agent for the Common Stock is The Bank of Boston.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, the Company will have outstanding
9,557,249 shares of Common Stock (assuming net exercise of a single
outstanding warrant and no exercise of options after March 31, 1996). Of these
shares, the 4,000,000 shares sold in this Offering will be freely tradeable
without restriction under the Securities Act, unless purchased by "affiliates"
of the Company.
 
  In addition to the 4,000,000 shares offered hereby, as of the effective date
of the Registration Statement (the "Effective Date"), 125,822 shares of Common
Stock will become eligible for sale in the public market in reliance on Rule
144(k) under the Securities Act of 1933, as amended (the "Securities Act").
Approximately 5,690,068 shares of Common Stock will become eligible for sale
in the public market, subject to compliance with Rules 144 and 701 under the
Securities Act, when certain 180-day lock-up agreements between the Company
and/or the Representatives and certain stockholders of the Company, including
officers, directors and Selling Stockholders, expire. In addition, holders of
warrants exercisable into an aggregate of 701,984 shares of Common Stock have
entered into 180-day lock-up agreements and no such shares may be sold 180
days after commencement of this offering upon exercise. Upon expiration of the
lock-up agreements and assuming the warrants are then exercised for cash, the
shares acquired upon exercise of the warrants, in the absence of registration,
may only be publicly resold pursuant to Rule 144. Furthermore, all of the
optionholders are subject to a 180-day lock-up period pursuant to their option
agreements and the holders of 100% of the shares of Common Stock subject to
options have entered into the same 180-day lock-up agreements as referenced
above. Montgomery Securities may, in its sole discretion, and at any time
without notice, release all or any portion of the securities subject to such
lock-up agreements.
 
  The Company intends to file a registration statement under the Securities
Act covering approximately 4,379,275 shares of Common Stock issued or reserved
for issuance under the 1992 Stock Option Plan, the 1996 Employee Stock
Purchase Plan and the 1996 Director Option Plan. That registration statement
is expected to be filed within 90 days after the date of this Prospectus and
will automatically become effective upon filing. Accordingly, all the shares
registered under that registration statement will, subject to Rule 144 volume
limitations applicable to affiliates, as that term is defined in the
Securities Act, be available for resale in the open market on such date. At
March 31, 1996, options to purchase 2,015,455 shares were issued and
outstanding under the 1992 Stock Option Plan, 1,083,295 of which were vested
and eligible for exercise as of that date.
 
  In general, under Rule 144 as currently in effect, beginning 90 days after
the Effective Date a person (or persons whose shares are aggregated) who has
beneficially owned Restricted Shares for at least two years, will be entitled
to sell in any three month period a number of shares that does not exceed the
greater of: (i) 1% of the number of shares of Common Stock then outstanding
(approximately 93,795 shares immediately after the offering assuming no
exercise of the Underwriters' over-allotment option) and (ii) the average
weekly trading volume of the Company's Common Stock in the Nasdaq National
Market during the four calendar weeks immediately preceding the date on which
notice of the sale is filed with the Securities and Exchange Commission. Sales
pursuant to Rule 144 are subject to certain requirements relating to manner of
sale, notice and availability of current public information about the Company.
A person (or persons whose shares are aggregated) who is not deemed to have
been an affiliate of the Company at any time during the 90 days immediately
preceding the sale and who has beneficially owned Restricted Shares for at
least three years is entitled to sell such shares pursuant to Rule 144(k)
without regard to the limitations and requirements described above.
 
  Holders of 6,429,552 shares of Common Stock of the Company have agreed with
the Company and/or the Representatives that until 180 days after the Effective
Date, they will not sell, offer to sell, contract to sell of otherwise sell,
dispose of, loan, pledge or grant any rights with respect to any shares of
Common Stock, any options or warrants to purchase shares of Common Stock, or
any securities convertible or exchangeable for shares of Common Stock, owned
directly by such holders or with respect to which they have power of
disposition, without the prior written consent of the Company and/or
Montgomery Securities, as the case may be. The Company has agreed with the
Representatives not to release any holders from such agreements without
 
                                      58
<PAGE>
 
the prior written consent of Montgomery Securities. The Company has also
agreed not to sell, offer to sell, contract to sell, grant any option to
purchase or otherwise dispose of any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock or any rights
to acquire Common Stock for a period of 180 days after the Effective Date
without the prior written consent of Montgomery Securities, subject to certain
limited exceptions including sales of shares under the Benefit Plans. The
lock-up agreements with the Representatives may be released at any time as to
all or any portion of the shares subject to such agreements at the sole
discretion of Montgomery Securities.
 
  Prior to this offering, there has been no prior public market for the Common
Stock and there is no assurance a significant public market for the Common
Stock will develop or be sustained after this offering. Sales of substantial
amounts of Common Stock in the public market could adversely affect the market

  The Representatives have advised the Company that the Underwriters initially
propose to offer the shares of Common Stock to the public on the terms set
forth on the cover page of this Prospectus. The Underwriters may allow to
selected dealers a concession of not more than $        per share; and the
Underwriters may allow, and such dealers may reallow, a concession of not more
than $        per share to certain other dealers. After the Offering, the
price and concessions and reallowances to dealers may be changed by the
Representatives. The Common Stock is offered subject to receipt and acceptance
by the Underwriters, and to certain other conditions, including the right to
reject orders in whole or in part.
 
  The Company has granted an option to the Underwriters, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to a
maximum of 600,000 additional shares of Common Stock to cover over-allotments,
if any, at the same price per share as the initial 4,000,000 shares to be
purchased by the Underwriters. To the extent the Underwriters exercise this
option, each of the Underwriters will be committed, subject to certain
conditions, to purchase such additional shares in approximately the same
proportion as set forth in the above table.
 
  The Underwriting Agreement contains covenants of indemnity among the
Underwriters, the Company and the Selling Shareholders against certain civil
liabilities, including liability under the Securities Act.
 
  Certain holders of the outstanding shares of Common Stock of the Company,
including all officers and directors of the Company, have agreed with the
Company and/or the Representatives that until 180 days after the Effective
Date, they will not sell, offer to sell, contract to sell or otherwise sell,
dispose of, loan, pledge or grant any rights with respect to any shares of
Common Stock, any options or warrants to purchase shares of Common Stock, or
any securities convertible or exchangeable for shares of Common Stock owned
directly by such holders or with respect to which they have power of
disposition, without the prior written consent of the Company and/or
Montgomery Securities, as the case may be. The Company has agreed with the
Representatives not to release any holder from such agreements without the
prior written consent of Montgomery Securities. The Company has also agreed
not to sell, offer to sell, contract to sell, grant any option to purchase or
otherwise dispose of any shares of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock or any rights to acquire
Common Stock for a period of 180 days after the Effective Date without the
prior written consent of Montgomery Securities, subject to certain limited
exceptions. The lock-up agreements may be released at any time as to all or
any portion of the shares subject to such agreements at the sole discretion of
Montgomery Securities.

  The Representatives have advised the Company that the Underwriters will not
confirm sales to accounts over which they exercise discretionary authority in
excess of 5% of the number of shares of Common Stock offered hereby.
 
  Prior to the offering, there has been no public market for the Common Stock
of the Company. Consequently, the initial public offering price will be
determined through negotiations among the Company and the Representatives.
Among the factors considered in such negotiations will be prevailing market
conditions, the net revenues and results of operations of the Company in
recent periods, market valuations of publicly traded companies that the
Company and the Representatives believe to be comparable to the Company,
estimates of business of the Company, the present state of the Company's
development and the current state of high technology industries and of the
economy as a whole. In this regard, in determining the anticipated offering
range for the Common Stock, the Underwriters considered, among other things,
the recent growth in the Company's business, the deleveraging of the Company's
balance sheet as a result of the offering, the market for network transport
products and system management applications and the current state of the
capital markets, particularly with respect to initial public offerings by
technology companies.
 
                                 LEGAL MATTERS
 
  The validity of the Common Stock offered hereby will be passed upon for the
Company by Wilson Sonsini Goodrich & Rosati, P.C., Palo Alto, California.
Certain legal matters with respect to this Offering are being passed upon for
the Underwriters by Brobeck, Phleger & Harrison LLP, San Francisco,
California.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
Interlink Computer Sciences, Inc. and Subsidiaries
 
  We have audited the accompanying consolidated balance sheets of Interlink
Computer Sciences, Inc. and Subsidiaries as of June 30, 1994 and 1995 and the
related consolidated statements of operations, stockholders' equity and cash
flows for each of the three years in the period ended June 30, 1995. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Interlink
Computer Sciences, Inc. and Subsidiaries as of June 30, 1994 and 1995, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended June 30, 1995 in conformity with generally
accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
           (Information as of March 31, 1996 and for the nine months
          ended March 31, 1995 and 1996 and thereafter is unaudited)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
NATURE OF OPERATIONS
 
  Interlink Computer Sciences, Inc. (the "Company") is a supplier of high
performance solutions for enterprise networked systems management. The Company
provides software and services which enable customers implementing
client/server systems to use their IBM and IBM-compatible MVS mainframes as
"enterprise servers" in distributed, heterogeneous client/server network
environments. The Company markets and sells its software products and services
primarily through its direct sales organization and to a lesser extent,
through international resellers and distributors to domestic and international
customers, including original equipment manufacturers. The Company's TCP/IP
products have generated substantially all of the Company's product and
maintenance and consulting revenues. During fiscal years 1993, 1994 and 1995
and the nine months ended March 31, 1996, sales of the TCP/IP products
accounted for approximately 66%, 85%, 84% and 83%, respectively, of the
Company's product revenues. Therefore, the Company's operating results,
particularly in the near term, are significantly dependent upon the continued
market acceptance of the TCP/IP products. The life cycles of the Company's
products are difficult to estimate due in part to the effect of future product
enhancements and competition. A decline in demand for the Company's products
as a result of competition, technological change or other factors would have a
material adverse affect on the Company's business, financial condition and
result of operations.
 
USE OF ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
BASIS OF PRESENTATION
 
  The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries after intercompany balances and transactions
have been eliminated.
 
FINANCIAL INSTRUMENTS
 
  Cash equivalents are highly liquid investments with original or remaining
maturities of three months or less at the date of purchase. Cash equivalents
present insignificant risk of changes in value because of interest rate
changes. The Company maintains its cash balances with high credit quality
financial institutions and has not experienced any material losses relating to
any investment instruments.
 
  Available-for-sale securities are carried at fair value, based on quoted
market prices, with the unrealized gains or losses, net of tax, reported in
shareholders' equity. The amortized cost of debt securities, which
approximated fair value at June 30, 1995 and consisted of a U.S. Treasury Note
with a six month maturity, is adjusted for amortization of premiums and
accretion of discounts to maturity, both of which are included in interest
income. At June 30, 1995, gross unrealized holding gains and losses were
insignificant. Realized gains and losses are recorded on the specific
identification method.
 
  The amounts reported for cash equivalents, receivables and other financial
instruments are considered to approximate fair values based upon comparable
market information available at the respective balance sheet dates. Financial
instruments that potentially subject the Company to concentrations of credit
risks comprise, principally cash and cash equivalents, available-for-sale
securities, trade accounts receivable, bank lines of credit and long-term
debt. The Company invests its excess cash primarily in commercial paper and
treasury notes that mature within one year. The carrying value of the
Company's line of credit and long-term debt approximates fair value as the
interest rates are variable or the debt has been discounted at current
interest rates.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
           (Information as of March 31, 1996 and for the nine months
          ended March 31, 1995 and 1996 and thereafter is unaudited)
 
CONCENTRATIONS
 
  At June 30, 1994 and 1995 and March 31, 1996, approximately 31%, 19%, and
52%, respectively, of the Company's cash and cash equivalents and available-
for-sale securities are invested in Europe with the remaining amounts invested
primarily in the United States and Canada.
 
  At June 30, 1994 and 1995 and March 31, 1996, approximately 51%, 62%, and
60%, respectively, of the Company's trade accounts receivable are due from
customers in Europe with the remaining receivables due from customers
primarily in the United States and Canada. The Company performs ongoing
evaluations of its customers' financial condition and does not require
collateral. The Company maintains allowances for potential credit losses and
such losses have been within management's expectations.
 
  Network access from the enterprise server to the network via the Company's
TCPaccess product requires a network controller, which the Company sells to
its customers. The Company's principal network controller, the 3762 Network
Controller, is supplied by one company. Sales of network controllers have
accounted for substantially all of the Company's hardware revenues to date,
and total hardware revenues have accounted for 27%, 23% and 25% of product
revenues in fiscal years 1993, 1994 and 1995, respectively, and 29% and 19% of
product revenues for the nine months ended March 31, 1995 and 1996,
respectively. In addition, the Company also relies upon this company for
network controller replacement parts. If the Company were unable to purchase
an adequate supply of such sole-sourced products on a timely basis, the
Company could be required to design a comparable product, qualify and develop
an alternative source, or redesign its products based upon different
components. Furthermore, IBM could use its position as a supplier of network
controllers to gain a competitive advantage over the Company. To date, the
Company has not experienced difficulty or significant delay in obtaining any
such sole-source products. However, there can be no assurance that the Company
will not face such difficulties or delays in the future. An inability of the
Company or its customers to obtain such sole-sourced controllers could
significantly delay shipment of products, which could have a material adverse
effect on the Company's business, financial condition and results of
operation.
 
GOODWILL
 
  Goodwill is amortized on a straight line basis and is stated net of
accumulated amortization of $82,000 and $144,000 at June 30, 1995 and March
31, 1996, respectively.
 
INVENTORIES
 
  Inventories are stated at the lower of cost (determined on a first-in,
first-out basis) or market. Inventories are principally comprised of finished
goods at June 30, 1994 and 1995 and March 31, 1996.
 
PROPERTY AND EQUIPMENT
 
  Property and equipment are stated at cost and depreciated using the
straight-line basis over estimated useful lives of three to five years.
Leasehold improvements and property under capital leases are amortized using a
straight-line basis over the shorter of their estimated useful lives or the
terms of the leases. Upon disposal, assets and related accumulated
depreciation are removed from the accounts and the related gain or loss is
included in operations.
 
  During fiscal year 1993 the Company reevaluated the estimated useful life of
certain of its assets being depreciated over five years, primarily computer
equipment, and reduced the useful life of such assets to three years. As a
result, depreciation expense recorded in fiscal year 1993 was $312,000 greater
than if the five year useful lives had been used to depreciate these assets.

REVENUE RECOGNITION
 
 Product Revenues
 
  Product revenues are recognized after shipment of the product, completion of
a trial period, if any, and receipt of a signed contract, if remaining
obligations are insignificant, collection of the resulting receivable is
probable and product returns are reasonably estimatible. Provisions for
estimated product returns, warranty costs and insignificant vendor obligations
are recorded at the time products are shipped.
 
 Maintenance and Consulting Revenues
 
  Maintenance and consulting revenues consist of maintenance and renewal fees
for providing product updates, technical support and related services for
software products, and training and consulting services fees. The Company
unbundles a portion of its initial product license revenues related to
software maintenance revenues based upon the amount charged for such services
when they are sold separately. Unbundled software maintenance revenues and
revenues from separately sold maintenance contracts are recognized ratably
over the related service period. Consulting services revenues from contracts
are generally recognized on the percentage-of-completion method. Training fees
are recognized as the related services are performed.
 
PRODUCT DEVELOPMENT COSTS
 
  Costs related to the conceptual formulation and design of software products
are expensed as product development while costs incurred subsequent to
establishing technological feasibility of software products are capitalized,
if material, until general release of the product. Generally, technological
feasibility is established when the software module performs its primary
functions described in its original specifications, contains convenience
features required for it to be usable in a production environment and is
completely documented. Amortization of capitalized software costs, which
begins when products are available for general release to customers, is
provided on a product-by-product basis at the greater of the amount computed
using the ratio of current revenues to the total current and anticipated
revenues or the straight-line basis over two years. During fiscal year 1995,
the Company wrote off capitalized software costs of $112,000 and in fiscal
years 1993, 1994 and 1995 capitalized software amortization was $237,000,
$154,000 and $259,000, respectively, and $250,000 and $23,000 for the nine
months ended March 31, 1995 and 1996, respectively.
 
ADVERTISING EXPENSE
 
  Advertising costs are expensed when incurred. In fiscal years 1993, 1994 and
1995 advertising expense was $76,000, $171,000 and $256,000, respectively, and
$210,000 and $192,000 for the nine months ended March 31, 1995 and 1996,
respectively.
 
INCOME TAXES
 
  Effective July 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 (SFAS 109), "Accounting for Income Taxes." The
Company has calculated its provision for income taxes for fiscal year 1994 and
1995 in accordance with SFAS 109, but has not restated prior years (see Note
8). Under SFAS 109, deferred tax assets and liabilities are determined based
on differences between financial reporting and tax bases of assets and
liabilities and are measured using the enacted tax rates and laws that will be
in effect when the differences are expected to reverse. The Company's
provision for income taxes for fiscal year 1993 was calculated in accordance
with the Accounting Principles Board Opinion No. 11 (APB 11), "Accounting for
Income Taxes," which uses the deferred method. Under APB 11, the deferred
income taxes were recorded to reflect timing differences in reporting certain
items for financial statement and income tax purposes and measured at the tax
rate in effect during the year the differences originated. Investment tax
credits are accounted for on the flow through method.

  The effect of the change on income taxes for fiscal year 1994 and the
cumulative effect of the change as of July 1, 1993 were not material.
 
FOREIGN CURRENCY TRANSLATION
 
  The functional currency for the majority of the Company's foreign operations
is the applicable local currency. The translation from the applicable foreign
currency to U.S. dollars is performed for balance sheet accounts using current
exchange rates in effect at the balance sheet date and for revenue and expense
accounts using the weighted average exchange rate during the period.
Adjustments resulting from such translation are reflected as a separate
component of stockholders' equity. Gains or losses resulting from foreign
currency transactions are included in the results of operations.
 
COMPUTATION OF NET INCOME (LOSS) PER SHARE
 
  Net income (loss) per share is computed using the weighted average number of
common and common equivalent shares outstanding during the period. Common
equivalent shares are included in the per share calculations where the effect
of their inclusion would be dilutive. Dilutive common equivalent shares
consist of the incremental common shares issuable upon conversion of
convertible preferred stock (using the "if converted" method) and stock
options and warrants, using the treasury stock method in fiscal 1993 and the
modified treasury stock method in all periods thereafter. Pursuant to
Securities and Exchange Commission Staff Accounting Bulletin No. 83, common
and common equivalent shares issued by the Company during the twelve months
preceding the initial filing of the Company's initial public offering, using
the modified treasury stock method and the public offering price per share,
have been included in the calculation of net income (loss) per share for all
periods presented.
 
RECLASSIFICATIONS
 
  Certain reclassifications have been made to prior year balances to conform
to current classifications.
 
RECENT PRONOUNCEMENTS
 
  During March 1995, the Financial Accounting Standards Board issued Statement
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-
Lived Assets to Be Disposed Of" (SFAS 121), which requires the Company to
review the impairment of long-lived assets, certain identifiable intangibles,
and goodwill related to those assets whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. SFAS 121 will become effective for the Company's 1997 fiscal
year. The Company does not expect SFAS 121 to have a material impact on the
Company's financial condition or results of operations.
 
  During October 1995, the Financial Accounting Standards Board issued
Statement No. 123, "Accounting for Stock-Based Compensation" (SFAS 123), which
establishes a fair value based method of accounting for stock based
compensation plans. While the Company is studying the impact of the
pronouncement, it continues to account for employee stock options under APB
Opinion No. 25, "Accounting for Stock Issued to Employees." SFAS 123 will be
effective for fiscal years beginning after December 15, 1995.
 
INTERIM FINANCIAL DATA (UNAUDITED)
 
  The unaudited financial statements for the nine months ended March 31, 1995
and 1996 have been prepared by the Company on a basis consistent with the
Company's audited financial statements and, in the opinion of management,
include all adjustments, consisting of normal recurring adjustments, necessary
for a fair presentation of the Company's operating results and financial
position, in accordance with generally accepted accounting principles. Results
for the nine months ended March 31, 1996 are not necessarily indicative of
future results.

2. ACQUISITIONS:
 
LENNOX AND PARTNER GMBH
 
  During fiscal year 1995, the Company purchased all of the capital stock of
Lennox and Partner GmbH ("Lennox") in exchange for 84,000 shares of the
Company's common stock and cash of $63,000. Under the terms of the purchase
agreement, the Company is obligated to make future cash payments to the
sellers of $58,000 and may be obligated to make additional cash payments of up
to $232,000 and to issue up to 12,000 additional shares of the Company's
common stock to certain Lennox sellers, who after the acquisition became
employees of the Company, contingent upon cumulative profitability of the
subsidiary. The acquisition was accounted for as a purchase transaction and
the results of operations of Lennox were included with those of the Company
after July 1, 1994, the date the acquisition was consummated. During 1995, the
Company paid and expensed $60,000 related to the cumulative profitability
requirements and recorded goodwill of $330,000 related to the transaction and
is amortizing such amounts over four years. The results of operations of
Lennox were not material to those of the Company in 1994.
 
  In December 1995, the cumulative profitability requirements specified in the
purchase agreement were met and the Company recorded an expense totaling
$216,000 related to both cash payments totaling $192,000 and the issuance of
15,000 shares of the Company's common stock with a fair value of $1.60 per
share.
 
NEW ERA SYSTEMS SERVICES LTD.
 
  Effective December 29, 1995, the Company acquired all of the outstanding
stock of New Era Systems Services Ltd. ("New Era"), a Canadian company that
develops, markets and supports storage management and software distribution
products. In the transaction, the Company paid cash of approximately
$11,000,000 and issued fully exercisable warrants to purchase 700,000 shares
of its common stock at $1.60 per share with a fair value of $315,000 (see Note
7). In addition, in conjunction with the acquisition, the Company issued non-
interest bearing notes payable to the shareholders of New Era aggregating
approximately $1,300,000, net of discounts for imputed interest of $133,000
(see Note 5). These amounts resulted in a purchase price for New Era of
$13,000,000 including accruals for direct acquisition costs and severance
costs and certain duplicate facilities related to the planned closure of New
Era's European subsidiary, all totaling approximately $500,000. The
acquisition has been accounted for as a purchase transaction and the results
of operations of New Era have been included with those of the Company since
December 29, 1995, the date the acquisition was consummated.
 
  The fair market value of the assets acquired from New Era, which was
determined through established valuation techniques used in the software
industry, and a summary of the consideration exchanged for these assets is as
follows (in thousands):

          ended March 31, 1995 and 1996 and thereafter is unaudited)
accumulated amortization related to purchased software products was $160,000.
The amount of the purchase price allocated to purchased research and
development, which had no alternative future use and relates to products for
which technological feasibility had not been established, was expensed at the
acquisition date.
 
  In addition, contingent consideration up to a total of $5,200,000 is payable
in cash on January 31, 1997 and 1998, upon the attainment of certain targeted
revenue levels for New Era software products and maintenance. These amounts
represent additional consideration paid for the acquisition of New Era, and up
to $2,700,000 will be recorded as purchased research and development and
expensed, if the products in research and development at the date of the
acquisition are still under research and development and up to $800,000 will
be recorded as purchased software products. Amounts paid in excess of amounts
allocated to purchased research and development and purchased software
products will be recorded as goodwill and amortized over the remaining life of
the goodwill, which is estimated at five years from the date of the
acquisition.
 
  Summarized below are the unaudited pro forma results of operations of the
Company as though New Era had been acquired at the beginning of fiscal 1995.
Adjustments have been made for the estimated increases in amortization related
to purchased software, increases and decreases in interest expense and income,
respectively, and other appropriate pro forma adjustments.

4. BANK LINE CREDIT:
 
  At June 30, 1995, the Company had available a line of credit with a bank
under which outstanding borrowings of $1,300,000 were collateralized by
substantially all the Company's assets. Borrowings under the line of credit
are limited to the lesser of (i) 80% of domestic accounts receivable plus 50%
of eligible foreign accounts receivable or (ii) $1,500,000, and bear interest
at the lender's prime rate plus 1.5% (10.5% at June 30, 1995). The agreement,
which expired on October 30, 1995, subjected the Company to covenants that
included maintaining certain financial ratios, minimum quarterly profitability
and restrictions on dividends, repurchase of stock, hypothecation of assets
and additional indebtedness.
 
  At March 31, 1996, the Company had available a line of credit with a bank
under a loan agreement, which also provided for certain long-term borrowings
(see Note 5). In conjunction with such loan agreement, the Company issued
warrants to purchase up to 162,500 shares of its common stock (see Note 7). At
March 31, 1996, $6,000,000 million was outstanding under the line of credit.
In May 1996, however, the Company revised its loan agreement with the bank
decreasing the line of credit to $5,000,000 and increasing the long-term
borrowings from $2,000,000 to $3,000,000. The line of credit expires on
November 29, 1996 and is collateralized by substantially all the assets of the
Company. Borrowings under the line of credit are limited to the lesser of
(i) 85% of domestic accounts receivable plus 70% of eligible foreign accounts
receivable not to exceed $2,500,000 or (ii) $5,000,000 and bear interest at
the lender's prime rate plus 1.5% (9.75% at March 31, 1996). Under the terms
of the agreement, the Company is required to maintain a certain minimum quick
ratio and tangible net worth and maximum debt to tangible net worth, as well
as specified quarterly profitability and is restricted from paying dividends,
repurchasing stock, hypothecating assets or incurring additional indebtedness.
Accordingly, the amounts outstanding under the line of credit at March 31,
1996 have been reduced to $5,000,000 and the long-term debt increased to
$3,000,000. In conjunction with the revision of this loan agreement, the
Company issued a fully exercisable warrant to purchase 12,500 shares of its
common stock at $6.40 per share, which expires April 25, 2003, and modified
the terms of the warrant it issued to the bank for 162,500 shares of its
common stock at $1.60 per share to provide that the maximum number of common
shares exercisable under the warrant are reduced to 150,000 and in the event
the Company completes an initial public offering by October 1, 1996, the
shares of common stock exercisable under that warrant are further reduced to
125,000.

  The note payable to bank bears interest at prime plus 2.5% (10.75% at March
31, 1996) and is payable in quarterly installments of principal beginning in
June 1996 with the final payment due in December 1998. The note payable, which
was issued to finance, in part, the New Era acquisition, is subject to the
same loan agreement described in Note 4 above for the March 31, 1996 note
payable.
 
  The Company has leased equipment under capital lease obligations maturing
through fiscal year 2000. The lease agreements require the Company to maintain
liability and property insurance.
 
  The notes payable to the former New Era shareholders were issued in
conjunction with the acquisition of New Era and are non-interest bearing,
unsecured and due on January 2, 1997. The notes payable are recorded net of a
discount of $100,000 at March 31, 1996, which reflects the estimated interest
to maturity at a rate of 10%, the interest rate at which other short-term
borrowings were available to the Company at the time of the acquisition.
 
  The Western Economic Development notes payable, which were assumed in
conjunction with the Company's acquisition of New Era, are unsecured, non-
interest bearing and are due in quarterly payments through June 2005. The
notes payable are recorded net of a discount of $636,000 at March 31, 1996
based on the Company's borrowing rate of 11%, the interest rate at which long-
term borrowings were available to the Company at the time of acquisition. In
addition, accelerated principal payments are required each quarter under these
notes payable beginning in June 1996. These accelerated principal payments are
calculated as 14% of quarterly HARBOR revenues in excess of approximately
$600,000. Under the terms of these notes, the Company is required to maintain
minimum equity in its Canadian subsidiary, is restricted from paying dividends
and must continue to conduct certain product development operations in Western
Canada until the notes are fully repaid.

DEBT RESTRUCTURING
 
  During fiscal year 1994, the Company exchanged borrowings of approximately
$5,000,000 for a cash payment of $3,000,000, a warrant to purchase 150,000
shares of the Company's common stock at $0.45 per share (see Note 7) and a
note payable of $495,000 and recorded an extraordinary gain related to the
debt restructuring of $1,320,000 net of income taxes of $41,000. This gain
represented the difference between the recorded amount of the debt prior to
the restructuring less cash paid, the estimated fair value of the warrants and
the note payable including all estimated interest payments through January 1,
1997. During fiscal year 1995, the Company paid the remaining $495,000 note
payable to the bank.

CONTINGENCY
 
  The Company and the Company's subsidiary in France are involved in a
commercial dispute with a former Italian distributor of the Company's
TCPaccess products. The former distributor alleged in a letter sent to the
Company that the Company had breached and unlawfully terminated the agreement
pursuant to which the former distributor was appointed a distributor of the
Company's products in Italy and asserted other related claims against the
Company. The letter demanded the former distributor's reinstatement as a
distributor, the execution of a written distribution agreement setting forth
the distribution arrangements between the parties, and compensation in an
unspecified amount to be paid to the former distributor for the harm that it
has suffered. The Company's Canadian subsidiary, New Era, has also used the
former distributor as a distributor of the HARBOR products in Italy pursuant
to a separate agreement and may or may not continue to do so in the future. No
legal claim has been filed nor has arbitration been invoked by the former
distributor regarding this matter. No provision for any liability that may
result upon resolution of this matter has been made in the accompanying
financial statements. Should the former distributor initiate legal proceedings
and prevail on such claims, the Company's business, financial condition and
results of operations could be materially adversely affected.
 
FOREIGN EXCHANGE CONTRACTS
 
  The Company had a foreign exchange contract outstanding with a notional
amount of $158,000 at June 30, 1995. Risk equal to the notional amount of the
contract arises from the possible inability of the counter party to meet the
terms of this contract. The other party to this contract is a major financial
institution. The Company does not expect any significant losses as a result of
default by the other party. The cash requirement under this foreign exchange
contract was not significant. Gains and losses resulting from this contract
are insignificant and are recorded in general and administrative expense.
 
MANAGEMENT AND KEY EMPLOYEE COMPENSATION AGREEMENTS
 
  The Company has agreements with certain members of management that provide
for the immediate acceleration of the exercisability of the options to
purchase the Company's common stock held by these individuals and for cash
bonuses if there is any reorganization, merger, or acquisition that results in
a change in the Company's ownership by at least 50%. Under these agreements,
the amount of additional compensation to be paid to each of these employees
would be determined based on a formula which considers the purchase price paid
for the Company and the amounts the preferred shareholders are entitled to
receive through liquidation preferences. All of these agreements terminate
immediately prior to the closing of an underwritten public offering of the
Company's common stock registered under the Securities Act of 1933, as
amended.
 
7. STOCKHOLDERS' EQUITY:
 
PREFERRED STOCK
 
  The Board of Directors has the authority to issue preferred stock in one or
more series and to fix the price, rights, preferences, privileges and
restrictions thereof, including dividend rights, dividend rates, conversion
rights, voting rights, terms of redemption, redemption prices, liquidation
preferences and the number of shares constituting a series or the designation
of such series, without any further vote or action by the Company's
stockholders.
 
  The Company's Series 1 preferred stock is initially convertible into common
stock, on a one for one basis, subject to certain antidilution adjustments.
Conversion is at the option of the holder, or is automatic upon the

earlier of the closing of a public offering of the Company's common stock at a
price of not less than $6.875 per share and an aggregate gross offering price
to the public of not less than $10,000,000 or upon the election of 50% of the
holders of the Series 1 preferred stock. The holders of preferred stock have
voting rights equal to the number of shares of common stock into which the
preferred stock is convertible. Further, holders of a certain majority of the
outstanding shares of the Series 1 preferred stock must approve a merger or
sale of substantially all the assets of the Company or amendments of the
Articles of Incorporation. The preferred stockholders are entitled to elect
two members of the Board of Directors.
 
  In the event of liquidation or merger, or upon the election of 50% of the
holders of the Series 1 preferred stock, the holders of the Series 1 preferred
stock are entitled to receive an initial preference amount of $2.75 per share
and all declared but unpaid dividends. Thereafter, the property and/or cash
shall be distributed 50% among the holders of Series 1 preferred stock and 50%
to the holders of common stock until the holders of the Series 1 preferred
stock have received $6.875 per share. Remaining assets shall be distributed to
the common stockholders until each has received $6.875 per share and then
ratably among the common and preferred stockholders, with the preferred
stockholders sharing on an as converted basis.
 
  The holders of Series 1 preferred stock are entitled to receive a non-
cumulative dividend of $0.19 per share, per annum, payable when, as and if
declared by the Board of Directors. The holders of the Series 1 preferred
stock also have certain registration rights.
 
INCENTIVE STOCK OPTION PLAN
 
  The Company terminated its 1988 Stock Option Plan and replaced it with a
1992 Stock Option Plan ("1992 Plan") under which 1,950,000 shares of common
stock were reserved for issuance at June 30, 1995. During the nine months
ended March 31, 1996, the Company reserved an additional 260,000 shares of
common stock under the 1992 Plan. All stock options outstanding or available
for grant under the 1988 Stock Option Plan were canceled or terminated,
respectively. Under the 1992 Plan, incentive stock options may be granted to
employees, officers and directors and non-statutory stock options to
employees, officers, directors or consultants at prices not lower than 100%
and 85%, respectively of the fair market value of the Company's common stock
at the date of grant as determined by the Board of Directors. Furthermore, the
1992 Plan provides that options are exercisable within the times, or upon the
events determined by the Board of Directors, or by a committee of the Board
appointed to administer the 1992 Plan, and are exercisable no later than seven
years from the date of grant. Generally, options become exercisable as to 9/48
after nine months from the date of grant and ratably thereafter over three
years and three months. Options to purchase 175,500 shares of the Company's
common stock with an exercise price of $0.55 per share, however, become
exercisable on the earlier to occur of the achievement of specified
performance milestones or five years from the date of grant.

  The valuation allowance decreased $820,000 in fiscal year 1995, primarily
due to the fact that management believes it is more likely than not that a
portion of the deferred tax asset will be realized in the next two fiscal
years primarily because of its expectation that both the Company and certain
of its subsidiaries will be profitable in fiscal years 1996 and 1997. At
December 31, 1995, the Company reduced its valuation allowance and recorded
the full amount of its net deferred tax assets, primarily because management
believes that it is more likely than not that the Company will have continued
profitability.

           (Information as of March 31, 1996 and for the nine months
          ended March 31, 1995 and 1996 and thereafter is unaudited)
 
  The Tax Reform Act of 1986 substantially changed the rules relating to net
operating loss and tax credit carryforwards in the case of an ownership change
of a corporation. The Company had such an ownership change, as defined, which
has limited the amount of net operating loss carryforwards that can be used in
any one year to approximately $135,000.

11. OTHER INCOME:
 
  In June 1993, the Company amended a development agreement with a major U.S.
corporation under which its remaining obligations were terminated, and the
title to a certain technology was transferred to the corporation in exchange
for $1,000,000.
 
12. EMPLOYEE BENEFIT PLAN:
 
  The Company has a 401(k) Profit Sharing Plan (the "Plan") qualified under
Section 401(k) of the Internal Revenue Code of 1986. All full-time U.S.
employees are eligible to participate in the Plan.
 
  Each eligible employee may elect to contribute to the Plan up to 15% of the
employee's annual compensation. The Company, at the discretion of its board of
directors, may make matching contributions to the Plan but has not done so for
fiscal years 1993, 1994 and 1995 and the nine months ended March 31, 1995 and
1996.
 
13. PRO FORMA FINANCIAL STATEMENT INFORMATION:
 
  Upon the closing of the Company's initial public offering, each outstanding
share of the Company's preferred stock will be converted automatically to
common stock. The pro forma effect of the conversion has been presented as a
separate column in the Company's balance sheet assuming the conversion had
occurred as of March 31, 1996.

March 31, 1996 to depict what the net loss per share would have been had the
common shares issuable upon the conversion of the outstanding Series 1
preferred stock been outstanding during such period.
 
14. SUBSEQUENT EVENTS:
 
  In June 1996, the Company adopted the 1996 Employee Stock Purchase Plan (the
"Purchase Plan") and a total of 500,000 shares of common stock has been
reserved for issuance under the Purchase Plan. Employees (including officers
and employee directors of the Company) are eligible to participate if they are
customarily employed for at least 20 hours per week and for more than five
months in any calendar year. The Purchase Plan permits eligible employees to
purchase common stock through payroll deductions, which may not exceed 15% of
any employee's compensation. The purchase price of the common stock under the
purchase Plan will be equal to 85% of the lesser of the fair market value per
share of common stock on the start date of the purchase period or on the date
on which the option is exercised. The Purchase Plan will terminate in June
2006, unless sooner terminated by the Board of Directors.
 
  In June 1996, the Company adopted the 1996 Director Option Plan (the
"Director Plan") under which a total of 100,000 shares of common stock are
reserved for issuance. The option grants under the Director Plan are automatic
and non-discretionary, and the exercise price of the options is 100% of the
fair market value of the common stock on the grant date. The Director Plan
provides for an initial grant of options to purchase 10,000 shares of common
stock to each non-employee director of the Company (an "Outside Director")
upon the effective date of this offering at a per share exercise price equal
to the initial public offering price. Each new non-employee director will
automatically be granted an option to purchase 10,000 shares of common stock
upon joining the Board of Directors. Subsequently, each Outside Director will
automatically be granted an additional option to purchase 2,500 shares of
common stock at the next meeting of the Board of Directors following the
annual meeting of shareholders in each year beginning with the 1997 annual
meeting of shareholders, if on such date, such Outside Director has served on
the Board of Directors for at least six months. The term of such options is
ten years.
 
  In June 1996, the Company's Board of Directors, subject to stockholder
approval, authorized the reincorporation of the Company in Delaware. As part
of this reincorporation, the outstanding shares of the predecessor California
corporation's common stock and all classes of its preferred stock will be
converted automatically into shares of the new Delaware corporation's common
stock and its preferred stock on a one-for-one basis. As a result of the
reincorporation, the Company's authorized common stock will increase to
25,000,000 shares, with a par value of $.001 per share, and, subject to the
conversion of all outstanding preferred stock upon the completion of the
initial public offering, the Company will be authorized to issue 5,000,000
shares of undesignated preferred stock.
 
  In June 1996, the Company increased the number of shares of common stock
reserved under the 1992 Plan by 1,700,000 shares to 3,910,000 shares (see Note
7).
 
  In May 1996, the Board of Directors authorized management of the Company to
file a registration statement with the Securities and Exchange Commission
permitting the Company to sell shares of its common stock to the public.

  On December 29, 1995, Interlink Computer Sciences, Inc. and Subsidiaries
("Interlink" or the "Company") acquired New Era Systems Services Ltd ("New
Era") and its HARBOR product line in exchange for cash and notes payable
totaling $12,400,000 and warrants to purchase 700,000 shares of its Common
Stock with additional contingent earnout payments totaling up to $5,200,000
due January 31, 1997 and 1998. HARBOR is an enterprise level software product
line providing systems management functions such as backup, restore, and
distribution for centralized network management.
 
  The following unaudited pro forma financial statements give effect to the
acquisition of substantially all of the assets and liabilities of New Era by
Interlink as if such acquisition had taken place as of July 1, 1994.
 
  The accompanying unaudited pro forma combined condensed consolidated
statement of operations for the year ended June 30, 1995 combines the
historical consolidated results of operations of the Company for the year
ended June 30, 1995 and the historical statement of operations of New Era for
the year ended February 28, 1995 as if the acquisition had occurred on July 1,
1994. The accompanying unaudited pro forma combined condensed consolidated
statement of operations for the nine months ended March 31, 1996 combines the
unaudited historical consolidated statement of operations of the Company for
the nine months ended March 31, 1996 and the historical statement of
operations of New Era for the six months ended November 30, 1995 as if the
acquisition had occurred on July 1, 1994. The results of operations of New Era
are only included for the six months ended November 30, 1995 as Interlink's
historical results of operations for the nine months ended March 31, 1996
include the results of New Era since the date of acquisition on December 29,
1995. The unaudited pro forma combined condensed consolidated statements of
operations give effect to the acquisition using the purchase method of
accounting based upon allocation of the purchase price of New Era, and the
adjustments described in the notes attached hereto.
 
  The pro forma combined information is not necessarily indicative of future
operations or the actual results that would have occurred had the acquisition
been consummated at the beginning of the periods presented. The pro forma
combined information and related adjustments are based upon available
information and upon certain assumptions which the Company believes are
reasonable. The pro forma combined condensed consolidated statements of
operations should be read in conjunction with the Company's and New Era's
historical financial statements and notes thereto incorporated by reference or
contained elsewhere herein.
 
  Certain line items are reclassified in order to remain consistent with the
Company's financial presentation. The pro forma combined information is
presented in U.S. dollars.

1. PURCHASE PRICE ALLOCATION:
 
  The following outlines the current estimates for the purchase price of the
acquisition of New Era. Management believes that there will be no material
adjustments to this allocation, which is based on an independent appraisal of
the assets purchased and liabilities assumed as follows (in thousands):
 
<TABLE>
   <S>                                                                  <C>
   Purchased research and development.................................. $10,158
   Purchased software products.........................................   3,199
                                                                        -------
                                                                         13,357
   Net book value of tangible assets acquired, net of liabilities
    assumed............................................................     356
                                                                        -------
                                                                        $13,001
                                                                        =======
</TABLE>
 
  In addition, contingent consideration up to a total of $5,200,000 is payable
in cash on January 31, 1997 and 1998, upon the attainment of certain targeted
revenue levels for New Era software products and maintenance. These amounts
represent additional consideration paid for the acquisition of New Era and up
to $2,700,000 will be recorded as purchased research and development and
expensed, if the products in research and development at the date of the
acquisition are still under research and development, and up to $800,000 will
be recorded as purchased software products. Amounts paid in excess of amounts
allocated to purchased research and development and purchased software
products will be recorded as goodwill and amortized over the remaining life of
the goodwill, which is estimated at five years from the date of the
acquisition.
 
2. PRO FORMA ADJUSTMENTS:
 
  To reflect (i) the amortization and depreciation resulting from the
allocation of the New Era purchase price to the assets acquired based on their
fair value, as determined by the management of Interlink and an independent
appraiser, (ii) the changes in interest income and expense resulting from the
reduction in cash and cash equivalents and additional borrowings,
respectively, and (iii) the income tax impact of the foregoing, certain pro
forma adjustments have been made to the accompanying pro forma combined
condensed consolidated statements of operations, assuming that the purchase
took place on July 1, 1994, as follows:
 
  (A) Elimination of a non-recurring charge of $10,158,000 for purchased
research and development. Due to the non-recurring nature of the purchased
research and development, it has been assumed to have been charged to
operations before the beginning of the pro forma periods.
 
  (B) Records the amortization of purchased software over five years as if the
acquisition occurred on July 1, 1994 resulting in amortization of $640,000 for
the year ended June 30, 1995 and $320,000 for the nine months ended March 31,
1996. Only six months of amortization is reflected in this adjustment for the
nine months ended March 31, 1996 as Interlink's historical consolidated
statement of operations included amortization of $160,000 for three months.
 
  (C) Records the interest expense of $984,000 for the year ended June 30,
1995 and $492,000 for the nine months ended March 31, 1996 on additional
short-term borrowings of $3,500,000 at a rate of 10.5% and additional long-
term borrowings, including non-interest-bearing borrowings assumed or incurred
in the acquisition, all totaling approximately $5,600,000. Only six months
interest is included in the adjustment for the nine months ended March 31,
1996 as Interlink's historical consolidated statement of operations includes
interest expense related to the acquisition for three months.
 
  (D) Records the decrease in interest income resulting from the reduction of
cash available for investment of approximately $4,500,000 disbursed in the
acquisition.

  (E) Adjusts the historical tax benefit of the Company for the tax benefit
realized from the deductible portion of entries (B), (C), and (D) at 40% for
Interlink and 45% for New Era, the incremental tax rate for each company.
 
  (F) Elimination of New Era's results of operations for the three months
ended May 31, 1995 from New Era's results of operations for the nine months
ended November 30, 1995 as Interlink's historical results of operations for
the nine months ended March 31, 1996 includes the results of operations of New
Era for three months from December 29, 1995, the date of acquisition, to March
31, 1996.

                               AUDITORS' REPORT
 
To the Directors of
 New Era Systems Services Ltd.
 
  We have audited the consolidated balance sheets of New Era Systems Services
Ltd. as at February 28, 1994 and 1995 and the consolidated statements of
operations and deficit and cash flows for each of the years in the three year
period ended February 28, 1995. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with auditing standards generally
accepted in Canada. Those standards require that we plan and perform an audit
to obtain reasonable assurance 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.
 
  In our opinion, these consolidated financial statements present fairly, in
all material respects, the financial position of New Era Systems Services Ltd.
as at February 28, 1994 and 1995 and the results of its operations and the
changes in its financial position for each of the years in the three year
period ended February 28, 1995 in accordance with accounting principles
generally accepted in the United States.

                             (IN CANADIAN DOLLARS)
 
  Information for the nine months ended November 30, 1994 and information for
             periods subsequent to February 28, 1995 is unaudited
 
1.SIGNIFICANT ACCOUNTING POLICIES
 
  The consolidated financial statements have been prepared in accordance with
accounting principles generally accepted in the United States. The Company is
incorporated under the laws of Canada and the consolidated financial
statements are presented in Canadian dollars.
 
BASIS OF CONSOLIDATION
 
  The consolidated financial statements include the accounts of Company and
its wholly owned subsidiaries. All significant intercompany balances and
transactions have been eliminated.
 
CASH EQUIVALENTS
 
  The Company considers all investments with a maturity of three months or
less from the date of purchase and money market funds to be cash equivalents.
 
REVENUE RECOGNITION
 
  Revenue from product sales is recognized upon delivery of the software, if
collectability is probable and remaining obligations are insignificant.
Estimated returns and provisions for estimated insignificant costs are
recorded upon shipment. Maintenance and support revenues, including revenue
bundled with initial licensing fees, are recognized ratably over the
contractual period of customer support.
 
FIXED ASSETS
 
  Fixed assets are stated at cost and depreciated on the straight-line basis
over estimated useful lives of the assets. These lives are generally two years
for computer equipment and software and five years for furniture and
equipment. Automobiles are amortized over the remaining term of the lease.
Upon disposal, assets and related accumulated depreciation are removed from
the accounts and the related gain or loss is included in operations.
 
PRODUCT DEVELOPMENT COSTS
 
  Costs related to the conceptual formulation and design of software products
are expensed as product development while costs incurred subsequent to
establishing technological feasibility of software products are capitalized,
if material, until general release of the product. There have been no product
development costs capitalized since the Company began active business
operations.
 
INVESTMENT
 
  The Company accounts for its investment in New Era Software Inc., using the
equity method. On December 1, 1994, additional shares were issued by New Era
Software Inc. diluting the Company's ownership interest from 40% to 34.2%.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
                             (IN CANADIAN DOLLARS)
 
  Information for the nine months ended November 30, 1994 and information for
             periods subsequent to February 28, 1995 is unaudited
 
INCOME TAXES
 
  Income taxes are accounted for in accordance with Statement of Financial
Accounting Standards No. 109 ("SFAS 109"), "Accounting for Income Taxes".
Under SFAS 109, deferred tax assets and liabilities are determined based on
differences between financial reporting and tax bases of assets and
liabilities and are measured using the enacted tax rates and laws that will be
in effect when the differences are expected to reverse.
 
FOREIGN CURRENCY TRANSLATION
 
  The Company's functional currency is Canadian dollars. Monetary assets and
liabilities denominated in foreign currencies are translated at exchange rates
in effect at the balance sheet date. Non-monetary assets and liabilities
denominated in foreign currencies are translated at rates in effect on the
dates the assets were acquired or liabilities were assumed. Revenues and
expenses are translated at rates of exchange prevailing on the transaction
dates. Gains and losses on translation are reflected in income when incurred.
 
INVESTMENT TAX CREDITS
 
  Investment tax credits relating to software development are recognized at
such time as their recovery is reasonably assured and are recorded as a
reduction of research and development expenses.
 
INTERIM FINANCIAL DATA (UNAUDITED)
 
  The unaudited financial statements for the nine months ended November 30,
1994 and 1995 have been prepared on the same basis as the audited financial
statements and, in the opinion of management, include all adjustments,
consisting of normal recurring adjustments, necessary for a fair presentation
of the financial position and results of operations, in accordance with
accounting principles generally accepted in the United States.
 
EARNINGS (LOSS) PER SHARE
 
  Earnings (loss) per common and common equivalent share is computed using the
weighted average number of common and dilutive common equivalent shares
outstanding during the period. Dilutive common equivalent shares consist of
stock options using the treasury stock method.

  The Selling Stockholders will bear their pro rata portion of underwriting
discounts and commissions, based on the number of shares offered by such
holders. All of the other costs and expenses of the Selling Stockholders will
be borne by the Registrant.
 
ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the Delaware General Corporation Law allows for the
indemnification of officers, directors and other corporate agents in the terms
sufficiently broad to indemnify such persons under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the
Securities Act of 1993, as amended (the "Act"). The Registrant's Certificate
of Incorporation to be filed upon the closing of the offering to which this
Registration Statement relates (Exhibit 3.3 hereto) and the Registrant's
Bylaws (Exhibit 3.4 hereto) provides for indemnification of the Registrant's
directors, officers, employees and other agents to the extent and under the
circumstances permitted by the Delaware General Corporation Law. The
Registrant also intends to enter into agreements with its directors and
executive officers that will require the Registrant among other things, to
indemnify them against certain liabilities that may arise by reason of their
status or service as directors to the fullest extent not prohibited by
Delaware law.
 
  The Underwriting Agreement provides for indemnification by the Underwriters
of the Registrant, its directors and officers, and by the Registrant of the
Underwriters, for certain liabilities, including liabilities arising under the
Act, and affords certain rights of contribution with respect thereto.

ITEM 17. UNDERTAKINGS.
 
  The undersigned Registrant hereby undertakes:
 
    (1) That for purposes of determining any liability under the Securities
  Act of 1933, 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 of 1933 shall be deemed
  to be part of this Registration Statement as of the time it was declared
  effective.
 
    (2) That for the purpose of determining any liability under the
  Securities Act of 1933, 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
  that time shall be deemed to be the initial bona fide offering thereof.
 
    (3) To provide to the underwriter at the closing specified in the
  underwriting agreement certificates in such denominations and registered in
  such names as required by the underwriter to permit prompt delivery to each
  purchaser.
 
                                     II-3
<PAGE>
 
    (4) Insofar as indemnification for liabilities arising under the
  Securities Act of 1933 may be permitted to directors, officers and
  controlling persons of the Registrant pursuant to the foregoing provisions,
  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 of 1933 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, 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 of 1933 and will be governed by the final adjudication of
  such issue.

  In connection with our audits of the financial statements of Interlink

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

__________ shares of the Company's issued and outstanding Common Stock to the

          You have advised the Company and the Selling Stockholders that the
Underwriters propose to make a public offering of their respective portions of

          The Company and each of the Selling Stockholders hereby confirm their
respective agreements with respect to the purchase of the Common Shares by the
Underwriters as follows:

          SECTION 2.  Representations and Warranties of the Company.  The
                      ---------------------------------------------      
Company represents and warrants to the several Underwriters that:

               (a) A registration statement on Form S-1 (File No. 333-_______)
     with respect to the Common Shares has been prepared by the Company in
     conformity with the requirements of the Securities Act of 1933, as amended
     (the "Act"), and the rules and regulations (the "Rules and Regulations") of
     the Securities and Exchange Commission (the "Commission") thereunder, and
     has been filed with the Commission.  The Company has prepared and has filed
     or proposes to file prior to the effective date of such registration
     statement an amendment or amendments to such registration statement, which
     amendment or amendments have been or will be similarly prepared.  There
     have been delivered to you two signed copies of such registration statement
     and amendments, together with two copies of each exhibit filed therewith.
     Conformed copies of such registration statement and amendments (but without
     exhibits) and of the related preliminary prospectus have been delivered to
     you in such reasonable quantities as you have requested for each of the
     Underwriters.  The Company will next file with the Commission one of the
     following:  (i) prior to effectiveness of such registration statement, a
     further amendment thereto, including the form of final prospectus, (ii) a
     final prospectus in accordance with Rules 430A and 424(b) of the Rules and
     Regulations, or (iii) a term sheet (the "Term Sheet") as described in and
     in accordance with Rules 434 and 424(b) of the Rules and Regulations.  As
     filed, the final prospectus, if one is used, or the Term Sheet and
     Preliminary Prospectus (as hereinafter defined), if a final prospectus is
     not used, shall include all Rule 430A Information (as hereinafter defined)
     and, except to the extent that you shall agree in writing to a
     modification, shall be in all substantive respects in the form furnished to
     you prior to the date and time that this Agreement was executed and
     delivered by the parties hereto, or, to the extent not completed at such
     date and time, shall contain only such specific additional information and
     other changes (beyond that contained in the latest Preliminary Prospectus
     (as hereinafter defined)) as the Company shall have previously advised you
     in writing would be included or made therein.

                                       2.
<PAGE>
 
          The term "Registration Statement" as used in this Agreement shall mean
     such registration statement at the time such registration statement becomes
     effective and, in the event any post-effective amendment thereto becomes
     effective prior to the First Closing Date (as hereinafter defined), shall
     also mean such registration statement as so amended; provided, however,
     that such term shall also include (i) all Rule 430A Information deemed to
     be included in such registration statement at the time such registration
     statement becomes effective as provided by Rule 430A of the Rules and
     Regulations and (ii) a registration statement, if any, filed pursuant to
     Rule 462(b) of the Rules and Regulations relating to the Common Shares.
     The term "Preliminary Prospectus" shall mean any preliminary prospectus
     referred to in the preceding paragraph and any preliminary prospectus
     included in the Registration Statement at the time it becomes effective
     that omits Rule 430A Information.  The term "Prospectus" as used in this
     Agreement shall mean either (i) the prospectus relating to the Common
     Shares in the form in which it is first filed with the Commission pursuant
     to Rule 424(b) of the Rules and Regulations, or (ii) if a Term Sheet is not
     used and no filing pursuant to Rule 424(b) of the Rules and Regulations is
     required, the form of final prospectus included in the Registration
     Statement at the time such registration statement becomes effective, or
     (iii) if a Term Sheet is used, the Term Sheet in the form in which it is
     first filed with the Commission pursuant to Rule 424(b) of the Rules and
     Regulations, together with the Preliminary Prospectus included in the
     Registration Statement at the time it becomes effective.  The term "Rule
     430A Information" means information with respect to the Common Shares and
     the offering thereof permitted to be omitted from the Registration
     Statement when it becomes effective pursuant to Rule 430A of the Rules and
     Regulations.

               (b) The Commission has not issued any order preventing or
     suspending the use of any Preliminary Prospectus, and each Preliminary
     Prospectus has conformed in all material respects to the requirements of
     the Act and the Rules and Regulations and, as of its date, has not included
     any untrue statement of a material fact or omitted to state a material fact
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading; and at the time the
     Registration Statement becomes effective, and at all times subsequent
     thereto up to and including each Closing Date hereinafter mentioned, the
     Registration Statement and the Prospectus, and any amendments or
     supplements thereto, will contain all material statements and information
     required to be included therein by the Act and the Rules and Regulations
     and will in all material respects conform to the requirements of the Act
     and the Rules and Regulations, and neither the Registration Statement nor
     the Prospectus, nor any amendment or

                                       3.
<PAGE>
 
     supplement thereto, will include any untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading; provided, however, no
     representation or warranty contained in this subsection 2(b) shall be
     applicable to information contained in or omitted from any Preliminary
     Prospectus, the Registration Statement, the Prospectus or any such
     amendment or supplement in reliance upon and in conformity with written
     information furnished to the Company by or on behalf of any Underwriter,
     directly or through the Representatives, specifically for use in the
     preparation thereof.

               (c) The Company does not own or control, directly or indirectly,
     any corporation, association or other entity other than the subsidiaries
     listed in Exhibit 22.1 to the Registration Statement.  The Company and each
     of its subsidiaries have been duly incorporated and are validly existing as
     corporations in good standing under the laws of their respective
     jurisdictions of incorporation, with full power and authority (corporate
     and other) to own and lease their properties and conduct their respective
     businesses and all proposed future businesses as described in the
     Prospectus; the Company owns all of the outstanding capital stock of its
     subsidiaries free and clear of all claims, liens, charges and encumbrances;
     the Company and each of its subsidiaries are in possession of and operating
     in compliance with all authorizations, licenses, permits, consents,
     certificates and orders material to the conduct of their respective
     businesses, all of which are valid and in full force and effect; the
     Company and each of its subsidiaries are duly qualified to do business and
     in good standing as foreign corporations in each jurisdiction in which the
     ownership or leasing of properties or the conduct of their respective
     businesses requires such qualification, except for jurisdictions in which
     the failure to so qualify would not have a material adverse effect upon the
     Company or the subsidiary; and no proceeding has been instituted in any
     such jurisdiction, revoking, limiting or curtailing, or seeking to revoke,
     limit or curtail, such power and authority or qualification.

               (d) The Company has an authorized and outstanding capital stock
     as set forth under the heading "Capitalization" in the Prospectus; the
     issued and outstanding shares of Common Stock have been duly authorized and
     validly issued, are fully paid and nonassessable, have been issued in
     compliance with all federal and state securities laws, were not issued in
     violation of or subject to any preemptive rights or other rights to
     subscribe for or purchase securities, and conform to the description
     thereof contained in the Prospectus.  All issued and outstanding shares of
     capital stock of each subsidiary of the Company have been duly authorized
     and validly issued and are fully

                                       4.
<PAGE>
 
     paid and nonassessable.  Except as disclosed in or contemplated by the
     Prospectus and the financial statements of the Company, and the related
     notes thereto, included in the Prospectus, neither the Company nor any
     subsidiary has outstanding any options to purchase, or any preemptive
     rights or other rights to subscribe for or to purchase, any securities or
     obligations convertible into, or any contracts or commitments to issue or
     sell, shares of its capital stock or any such options, rights, convertible
     securities or obligations.  The description of the Company's stock option,
     stock bonus and other stock plans or arrangements, and the options or other
     rights granted and exercised thereunder, set forth in the Prospectus
     accurately and fairly presents the information required to be shown with
     respect to such plans, arrangements, options and rights.

               (e) The Common Shares to be sold by the Company have been duly
     authorized and, when issued, delivered and paid for in the manner set forth
     in this Agreement, will be duly authorized, validly issued, fully paid and
     nonassessable, and will conform to the description thereof contained in the
     Prospectus.  No preemptive rights or other rights to subscribe for or
     purchase exist with respect to the issuance and sale of the Common Shares
     by the Company pursuant to this Agreement.  No stockholder of the Company
     has any right which has not been waived to require the Company to register
     the sale of any shares owned by such stockholder under the Act in the
     public offering contemplated by this Agreement.  No further approval or
     authority of the stockholders or the Board of Directors of the Company will
     be required for the transfer and sale of the Common Shares to be sold by
     the Selling Stockholders or the issuance and sale of the Common Shares to
     be sold by the Company as contemplated herein.

               (f) The Company has full legal right, power and authority to
     enter into this Agreement and perform the transactions contemplated hereby.
     This Agreement has been duly authorized, executed and delivered by the
     Company and constitutes a valid and binding obligation of the Company in
     accordance with its terms.  The making and performance of this Agreement by
     the Company and the consummation of the transactions herein contemplated
     will not violate any provisions of the certificate of incorporation or
     bylaws, or other organizational documents, of the Company or any of its
     subsidiaries, and will not conflict with, result in the breach or violation
     of, or constitute, either by itself or upon notice or the passage of time
     or both, a default under any agreement, mortgage, deed of trust, lease,
     franchise, license, indenture, permit or other instrument to which the
     Company or any of its subsidiaries is a party or by which the Company or
     any of its subsidiaries or any of its respective properties may be bound or
     affected, any statute or any authorization, judgment, decree, order, rule
     or

                                       5.

     regulation of any court or any regulatory body, administrative agency or
     other governmental body applicable to the Company or any of its
     subsidiaries or any of their respective properties.  No consent, approval,
     authorization or other order of any court, regulatory body, administrative
     agency or other governmental body is required for the execution and
     delivery of this Agreement or the consummation of the transactions
     contemplated by this Agreement, except for compliance with the Act, the
     Blue Sky laws applicable to the public offering of the Common Shares by the
     several Underwriters and the clearance of such offering with the National
     Association of Securities Dealers, Inc. (the "NASD").

               (g) All corporate action on the part of the California
     Corporation and the Company, and their respective Boards of Directors,
     shareholders and stockholders, as the case may be, necessary for the
     authorization, execution, delivery and performance of the Merger Agreement,
     effecting the reincorporation of the California Corporation under the laws
     of State of Delaware, has been taken.  The Merger Agreement has been duly
     executed by each of the California Corporation and the Company.  The Merger
     Agreement has been filed with the Secretary of the State of Delaware and
     shall be effective on or before the First Closing Date (as hereinafter
     defined).  Each of the California Corporation and the Company had all
     corporate power and authority to execute and deliver the Merger Agreement,
     to file the Merger Agreement with the Secretary of the State of California
     and the Secretary of the State of Delaware and to consummate the
     reincorporation contemplated by the Merger Agreement, and the Merger
     Agreement at the time of execution and filing constituted a valid and
     binding obligation of each of the California Corporation and the Company,
     enforceable in accordance with its terms.  The merger between the
     California Corporation and the Company was effected pursuant to a valid
     qualification under California state securities laws.

               (h) Coopers & Lybrand L.L.P., who have expressed their opinion
     with respect to the financial statements and schedules filed with the
     Commission as a part of the Registration Statement and included in the
     Prospectus and in the Registration Statement, and Ernst & Young Chartered
     Accountants L.L.P., who have expressed their opinion with respect to the
     financial statements of New Era Systems Services, Ltd., are independent
     accountants as required by the Act and the Rules and Regulations.

               (i) The financial statements and schedules of the Company, New
     Era Systems Services, Ltd., and, subject to the qualifications expressly
     set forth in the Prospectus under the caption "Pro Forma Combined Condensed
     Consolidated Financial Statements," the Company on a pro forma

                                       6.
<PAGE>
 
     consolidated basis, and, in each case, the related notes thereto, included
     in the Registration Statement and the Prospectus present fairly the
     financial position of the Company and New Era Systems Services, Ltd., as
     the case may be, as of the respective dates of such financial statements
     and schedules, and the results of operations and changes in financial
     position of the Company and New Era Systems Services, Ltd., as the case may
     be, for the respective periods covered thereby.  Such statements, schedules
     and related notes have been prepared in accordance with United States
     generally accepted accounting principles applied on a consistent basis as
     certified by the independent accountants named in subsection 2(h).  No
     other financial statements or schedules are required to be included in the
     Registration Statement.  The selected financial data set forth in the
     Prospectus under the captions "Capitalization" and "Selected Consolidated
     Financial Data" fairly present the information set forth therein on the
     basis stated in the Registration Statement.

               (j) Except as disclosed in the Prospectus, and except as to
     defaults which individually or in the aggregate would not be material to
     the Company, neither the Company nor any of its subsidiaries is in
     violation or default of any provision of its certificate of incorporation
     or bylaws, or other organizational documents, or is in breach of or default
     with respect to any provision of any agreement, judgment, decree, order,
     mortgage, deed of trust, lease, franchise, license, indenture, permit or
     other instrument to which it is a party or by which it or any of its
     properties are bound; and there does not exist any state of facts which
     constitutes an event of default on the part of the Company or any such
     subsidiary as defined in such documents or which, with notice or lapse of
     time or both, would constitute such an event of default.

               (k) There are no contracts or other documents required to be
     described in the Registration Statement or to be filed as exhibits to the
     Registration Statement by the Act or by the Rules and Regulations which
     have not been described or filed as required.  The contracts so described
     in the Prospectus are in full force and effect on the date hereof; and
     neither the Company nor any of its subsidiaries, nor to the best of the
     Company's knowledge, any other party is in breach of or default under any
     of such contracts.

               (l) Except as disclosed in the Prospectus, there are no legal or
     governmental actions, suits or proceedings pending or, to the best of the
     Company's knowledge, threatened to which the Company or any of its
     subsidiaries is or may be a party or of which property owned or leased by
     the Company or any of its subsidiaries is or may be the subject, or related
     to environmental or discrimination matters, which actions, suits or
     proceedings might,

                                       7.

     individually or in the aggregate, prevent or adversely affect the
     transactions contemplated by this Agreement or result in a material adverse
     change in the condition (financial or otherwise), properties, business,
     results of operations or prospects of the Company and its subsidiaries; and
     no labor disturbance by the employees of the Company or any of its
     subsidiaries exists or is imminent which might be expected to affect
     adversely such condition, properties, business, results of operations or
     prospects.  Neither the Company nor any of its subsidiaries is a party or
     subject to the provisions of any material injunction, judgment, decree or
     order of any court, regulatory body, administrative agency or other
     governmental body.

               (m) The Company or the applicable subsidiary has good and
     marketable title to all the properties and assets reflected as owned in the
     financial statements hereinabove described (or elsewhere in the
     Prospectus), subject to no lien, mortgage, pledge, charge or encumbrance of

     business in compliance with all applicable laws, rules and regulations of
     the jurisdictions in which it is conducting business, including, without
     limitation, all applicable local, state and federal environmental laws and

          arrangements, liens, encumbrances, equities, security interests,
          restrictions and claims whatsoever; and upon delivery

                                      10.

          Irrevocable Power of Attorney and caused to be executed and delivered
          on his behalf a Custody Agreement (hereinafter collectively referred
          to as the "Stockholders Agreement") and in connection herewith such
          Selling Stockholder further represents, warrants and agrees that such
          Selling Stockholder has deposited in custody, under the Stockholders
          Agreement, with the agent named therein (the "Agent") as custodian,
          certificates in negotiable form for the Common Shares to be sold
          hereunder by such Selling Stockholder, for the purpose of further
          delivery pursuant to this Agreement.  Such Selling Stockholder agrees

          Stockholder hereunder shall not be terminated, except as provided in
          this Agreement or in the Stockholders Agreement, by any act of such
          Selling Stockholder, by operation of law, by the death or incapacity
          of such Selling Stockholder or by the occurrence of any other event.
          If the Selling Stockholder should die or become incapacitated, or if
          any other event should occur, before the delivery of the Common Shares
          hereunder, the documents evidencing Common Shares then on deposit with
          the Agent shall be delivered by the Agent in accordance with the terms
          and conditions of this Agreement as if such death, incapacity or other
          event had not occurred, regardless of whether or not the Agent shall
          have received notice thereof.  This Agreement and the Stockholders
          Agreement have been duly executed and delivered by or on behalf of
          such Selling Stockholder and the form of such Stockholders Agreement
          has been delivered to you.

                  (iii)  The performance of this Agreement and the Stockholders
          Agreement and the consummation of the transactions contemplated hereby
          and by the Stockholders Agreement will not result in a breach or
          violation by such Selling Stockholder of any of the terms or
          provisions of, or constitute a default by such Selling Stockholder
          under, any indenture, mortgage, deed of trust, trust (constructive or
          other), loan agreement, lease, franchise, license or other agreement
          or instrument to which such Selling Stockholder is a party or by which

                   (iv) Such Selling Stockholder has not taken and will not
          take, directly or indirectly, any action designed to or which has
          constituted or which might reasonably be expected to cause or result
          in stabilization or manipulation of the price of any security of the
          Company to facilitate the sale or resale of the Common Shares.

                    (v) Each Preliminary Prospectus and the Prospectus, insofar
          as it has related to such Selling Stockholder, has conformed in all
          material respects to the requirements of the Act and the Rules and
          Regulations and has not included any untrue statement of a material
          fact or omitted to state a material fact necessary to make the
          statements therein not misleading in light of the circumstances under
          which they were made; and neither the Registration Statement nor the
          Prospectus, nor any amendment or supplement thereto, as it relates to
          such Selling Stockholder, will include any untrue statement of a
          material fact or omit to state any material fact required to be stated
          therein or necessary to make the statements therein not misleading.

                   (vi) Such Selling Stockholder is not aware that any of the

          SECTION 4.  Representations and Warranties of the Underwriters.  The
                      --------------------------------------------------

the Company and to the Selling Stockholders that the information set forth (i)
on the cover page of the Prospectus with respect to price, underwriting
discounts and commissions and terms of offering and (ii) under "Underwriting" in

                                      12.

represent and warrant that they have been authorized by each of the other
Underwriters as the Representatives to enter into this Agreement on its behalf
and to act for it in the manner herein provided.

          SECTION 5.  Purchase, Sale and Delivery of Common Shares.  On the
                      --------------------------------------------         
basis of the representations, warranties and agreements herein contained, but
subject to the terms and conditions herein set forth, (i) the Company agrees to
issue and sell to the Underwriters __________ of the Firm Common Shares, and
(ii) the Selling Stockholders agree, severally and not jointly, to sell to the
Underwriters in the respective amounts set forth in Schedule B hereto, an
aggregate of ________ of the Firm Common Shares.  The Underwriters agree,
severally and not jointly, to purchase from the Company and the Selling
Stockholders, respectively, the number of Firm Common Shares described below.
The purchase price per share to be paid by the several Underwriters to the
Company and to the Selling Stockholders, respectively, shall be $_________ per
share.

          The obligation of each Underwriter to the Company shall be to purchase
from the Company that number of full shares which (as nearly as practicable, as
determined by you) bears to __________ the same proportion as the number of
shares set forth opposite the name of such Underwriter in Schedule A hereto
bears to the total number of Firm Common Shares.  The obligation of each
Underwriter to the Selling Stockholders shall be to purchase from the Selling
Stockholders that number of full shares which (as nearly as practicable, as
determined by you) bears to __________ the same proportion as the number of
shares set forth opposite the name of such Underwriter in Schedule A hereto
bears to the total number of Firm Common Shares.

          Delivery of certificates for the Firm Common Shares to be purchased by
the Underwriters and payment therefor shall be made at the offices of Montgomery
Securities, 600 Montgomery Street, San Francisco, California (or such other
place as may be agreed upon by the Company and the Representatives) at such time
and date, not later than the third (or, if the Firm Common Shares are priced, as
contemplated by Rule 15c6-1(c) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), after 4:30 P.M. Washington D.C. Time, the fourth)
full business day following the first date that any of the Common Shares are
released by you for sale to the public, as you shall designate by at least 48
hours' prior notice to the Company (or at such other time and date, not later
than one week after such third or fourth, as the case may be, full business day
as may be agreed upon by the Company and the Representatives) (the "First
Closing Date"); provided, however, that if the Prospectus is at any time prior
to the First Closing Date recirculated to the public, the First Closing Date
shall occur upon the later of the third or fourth, as the case may be, full
business day following the first date that any of the Common Shares are released
by you for sale

                                      13.
<PAGE>
 
to the public (as set forth above) or the date that is 48 hours after the date
that the Prospectus has been so recirculated.

          Delivery of certificates for the Firm Common Shares shall be made by
or on behalf of the Company and the Selling Stockholders to you, for the
respective accounts of the Underwriters with respect to the Firm Common Shares
to be sold by the Company and by the Selling Stockholders against payment by
you, for the accounts of the several Underwriters, of the purchase price
therefor by certified or official bank checks payable in next day funds to the
order of the Company and of the Agent in proportion to the number of Firm Common
Shares to be sold by the Company and the Selling Stockholders, respectively.
The certificates for the Firm Common Shares shall be registered in such names
and denominations as you shall have requested at least two full business days
prior to the First Closing Date, and shall be made available for checking and
packaging on the business day preceding the First Closing Date at a location in
New York, New York, as may be designated by you.  Time shall be of the essence,
and delivery at the time and place specified in this Agreement is a further
condition to the obligations of the Underwriters.

          In addition, on the basis of the representations, warranties and
agreements herein contained, but subject to the terms and conditions herein set
forth, the Company hereby grants an option to the several Underwriters to
purchase, severally and not jointly, up to an aggregate of __________ Optional
Common Shares at the purchase price per share to be paid for the Firm Common
Shares, for use solely in covering any over-allotments made by you for the
account of the Underwriters in the sale and distribution of the Firm Common
Shares.  The option granted hereunder may be exercised at any time (but not more
than once) within 30 days after the first date that any of the Common Shares are
released by you for sale to the public, upon notice by you to the Company
setting forth the aggregate number of Optional Common Shares as to which the
Underwriters are exercising the option, the names and denominations in which the
certificates for such shares are to be registered and the time and place at
which such certificates will be delivered.  Such time of delivery (which may not
be earlier than the First Closing Date), being herein referred to as the "Second
Closing Date," shall be determined by you, but if at any time other than the
First Closing Date shall not be earlier than three nor later than five full
business days after delivery of such notice of exercise.  The number of Optional
Common Shares to be purchased by each Underwriter shall be determined by
multiplying the number of Optional Common Shares to be sold by the Company
pursuant to such notice of exercise by a fraction, the numerator of which is the
number of Firm Common Shares to be purchased by such Underwriter as set forth
opposite its name in Schedule A and the denominator of which is _________
(subject to such adjustments to eliminate any fractional share purchases as you
in your discretion may make).  Certificates for the Optional Common Shares will
be made available for checking

                                      14.
<PAGE>
 
and packaging on the business day preceding the Second Closing Date at a
location in New York, New York, as may be designated by you. The manner of
payment for and delivery of the Optional Common Shares shall be the same as for
the Firm Common Shares purchased from the Company as specified in the two
preceding paragraphs.  At any time before lapse of the option, you may cancel
such option by giving written notice of such cancellation to the Company.  If
the option is cancelled or expires unexercised in whole or in part, the Company
will deregister under the Act the number of Option Shares as to which the option
has not been exercised.  Notwithstanding the foregoing, in the event that the
Registration Statement is amended or the Prospectus is supplemented between the
date hereof and any Closing Date, the Underwriters shall have the right to delay
the Closing Date to a date which will allow the Underwriters the time necessary
to distribute the Prospectus as amended or supplemented.

          You have advised the Company and the Selling Stockholders that each
Underwriter has authorized you to accept delivery of its Common Shares, to make
payment and to receipt therefor.  You, individually and not as the
Representatives of the Underwriters, may (but shall not be obligated to) make
payment for any Common Shares to be purchased by any Underwriter whose funds
shall not have been received by you by the First Closing Date or the Second
Closing Date, as the case may be, for the account of such Underwriter, but any
such payment shall not relieve such Underwriter from any of its obligations
under this Agreement.

          Subject to the terms and conditions hereof, the Underwriters propose
to make a public offering of their respective portions of the Common Shares as
soon after the effective date of the Registration Statement as in the judgment
of the Representatives is advisable and at the public offering price set forth
on the cover page of and on the terms set forth in the Prospectus.

          SECTION 6.  Covenants of the Company.  The Company covenants and
                      ------------------------                            
agrees that:

               (a) The Company will use its best efforts to cause the
     Registration Statement and any amendment thereof, if not effective at the
     time and date that this Agreement is executed and delivered by the parties
     hereto, to become effective.  If the Registration Statement has become or
     becomes effective pursuant to Rule 430A of the Rules and Regulations, or
     the filing of the Prospectus is otherwise required under Rule 424(b) of the
     Rules and Regulations, the Company will file the Prospectus, properly
     completed, pursuant to the applicable paragraph of Rule 424(b) of the Rules
     and Regulations within the time period prescribed and will provide evidence
     satisfactory to you of such timely filing.  The Company will promptly
     advise you in writing (i)

                                      15.
<PAGE>
 
     of the receipt of any comments of the Commission, (ii) of any request of
     the Commission for amendment of or supplement to the Registration Statement
     (either before or after it becomes effective), any Preliminary Prospectus
     or the Prospectus or for additional information, (iii) when the
     Registration Statement shall have become effective and (iv) of the issuance
     by the Commission of any stop order suspending the effectiveness of the
     Registration Statement or of the institution of any proceedings for that
     purpose.  If the Commission shall enter any such stop order at any time,
     the Company will use its best efforts to obtain the lifting of such order
     at the earliest possible moment.  The Company will not file any amendment
     or supplement to the Registration Statement (either before or after it
     becomes effective), any Preliminary Prospectus or the Prospectus of which
     you have not been furnished with a copy a reasonable time prior to such
     filing or to which you reasonably object or which is not in compliance with
     the Act and the Rules and Regulations.

               (b) The Company will prepare and file with the Commission,
     promptly upon your request, any amendments or supplements to the
     Registration Statement or the Prospectus which in your judgment may be
     necessary or advisable to enable the several Underwriters to continue the
     distribution of the Common Shares and will use its best efforts to cause
     the same to become effective as promptly as possible.  The Company will
     fully and completely comply with the provisions of Rule 430A of the Rules
     and Regulations with respect to information omitted from the Registration
     Statement in reliance upon such Rule.

               (c) If at any time within the nine-month period referred to in
     Section 10(a)(3) of the Act during which a prospectus relating to the
     Common Shares is required to be delivered under the Act any event occurs,
     as a result of which the Prospectus, including any amendments or
     supplements, would include an untrue statement of a material fact, or omit
     to state any material fact required to be stated therein or necessary to
     make the statements therein not misleading, or if it is necessary at any
     time to amend the Prospectus, including any amendments or supplements, to
     comply with the Act or the Rules and Regulations, the Company will promptly
     advise you thereof and will promptly prepare and file with the Commission,
     at its own expense, an amendment or supplement which will correct such
     statement or omission or an amendment or supplement which will effect such
     compliance and will use its best efforts to cause the same to become
     effective as soon as possible; and, in case any Underwriter is required to
     deliver a prospectus after such nine-month period, the Company upon
     request, but at the expense of such Underwriter, will promptly prepare such
     amendment or amendments to the Registration Statement and such Prospectus
     or Prospectuses as may be necessary to

                                      16.
<PAGE>
 
     permit compliance with the requirements of Section 10(a)(3) of the Act.

               (d) As soon as practicable, but not later than 45 days after the
     end of the first quarter ending after one year following the effective date
     of the Registration Statement (as defined in Rule 158(c) of the Rules and
     Regulations, the "Effective Date"), the Company will make generally
     available to its security holders an earnings statement (which need not be
     audited) covering a period of 12 consecutive months beginning after the
     effective date of the Registration Statement which will satisfy the
     provisions of the last paragraph of Section 11(a) of the Act.

               (e) During such period as a prospectus is required by law to be
     delivered in connection with sales by an Underwriter or dealer, the
     Company, at its expense, but only for the nine-month period referred to in
     Section 10(a)(3) of the Act, will furnish to you and the Selling
     Stockholders or mail to your order copies of the Registration Statement,
     the Prospectus, the Preliminary Prospectus and all amendments and
     supplements to any such documents in each case as soon as available and in
     such quantities as you and the Selling Stockholders may request, for the
     purposes contemplated by the Act.

               (f) The Company shall cooperate with you and your counsel in
     order to qualify or register the Common Shares for sale under (or obtain
     exemptions from the application of) the Blue Sky laws of such jurisdictions
     as you designate, will comply with such laws and will continue such
     qualifications, registrations and exemptions in effect so long as
     reasonably required for the distribution of the Common Shares.  The Company
     shall not be required to qualify as a foreign corporation or to file a
     general consent to service of process in any such jurisdiction where it is
     not presently qualified or where it would be subject to taxation as a
     foreign corporation.  The Company will advise you promptly of the
     suspension of the qualification or registration of (or any such exemption
     relating to) the Common Shares for offering, sale or trading in any

     trading in the Company's Common Stock in California), will comply with such
     Blue Sky laws and will continue such qualifications, registrations and
     exemptions in effect for a period of five years after the date hereof.

               (k) The Company will use its best efforts to maintain the Common

          Underwriters and dated the First Closing Date, or the Second Closing
          Date (in the latter case with respect to the Company only), as the
          case may be, to the effect that:

                         (1) Each of the Company and its subsidiaries has been
               duly incorporated and is validly existing as a corporation in
               good standing under the laws of its jurisdiction of
               incorporation, is duly qualified to do business as a foreign
               corporation and is in good standing in all other jurisdictions
               where the ownership or leasing of properties or the conduct of
               its business requires such qualification, except for
               jurisdictions in which the failure to so qualify would not have a
               material adverse effect on the Company and its subsidiaries, and
               has full corporate power and authority to own its properties and
               conduct its business and all future proposed business as
               described in the Registration Statement;

                         (2) The authorized, issued and outstanding capital
               stock of the Company is as set forth under the caption
               "Capitalization" in the Prospectus and conforms as to legal
               matters in all material respects to the description thereof
               contained in the Registration Statement and the Prospectus under

               proceedings have been taken in order to authorize validly such
               authorized Common Stock; all outstanding shares of Common Stock
               (including the Firm Common Shares and any Optional Common Shares)

               purchase any securities and conform to the description thereof
               contained in the Prospectus; without limiting the foregoing,
               there are no preemptive or other rights to subscribe for or
               purchase any of the Common Shares to be sold by the Company
               hereunder;

                         (3) All of the issued and outstanding shares of capital
               stock of the Company's subsidiaries have been duly and validly
               authorized and issued, are fully paid and nonassessable and are
               owned beneficially by the Company free and clear of all liens,
               encumbrances, equities, claims, security interests, voting trusts
               or other defects of title whatsoever;

                         (4) The certificates evidencing the Common Shares to be
               delivered hereunder are in due and proper form under Delaware
               law, and when duly countersigned by the Company's transfer agent
               and registrar, and delivered to you or upon your order against
               payment of the agreed consideration therefor in accordance with
               the provisions of this Agreement, the Common Shares represented
               thereby will be duly authorized and validly issued, fully paid
               and nonassessable, will not have been issued in violation of or
               subject to any preemptive rights or other rights to subscribe for
               or purchase securities and will conform in all respects to the
               description thereof contained in the Prospectus;

                         (5) The execution and delivery of the Merger Agreement,
               effecting the reincorporation of the California Corporation under
               the laws of the State of Delaware, were duly authorized by all
               necessary corporate action on the part of each of the California
               Corporation and the Company and were duly authorized by all
               necessary action on the part of the stockholders of each of the
               California Corporation and the Company;

                         (6) Each of the California Corporation and the Company
               had all corporate power and authority to execute and deliver the

               consummate the reincorporation contemplated by the Merger
               Agreement; the Merger Agreement at the time of execution and
               filing constituted a valid and binding obligation of each of the
               California Corporation and the Company, enforceable in accordance
               with its terms, except as enforceability may be limited by

               laws of the State of California and the State of Delaware;

                         (7) Except as disclosed in or specifically
               contemplated by the Prospectus, to the best of such counsel's
               knowledge, there are no outstanding options, warrants or other
               rights calling for the issuance of, and no commitments, plans or
               arrangements to issue, any shares of capital stock of the Company
               or any security convertible into or exchangeable for capital
               stock of the Company;

               Selling Stockholders will not result in a breach of, or

               Stockholders is a party or by which any of the Selling
               Stockholders or any of their properties may be bound, or violate
               any statute, judgment, decree, order, rule or regulation known to
               such counsel of any court or governmental body having
               jurisdiction over any of the Selling Stockholders or any of their
               properties; and to the best of such counsel's knowledge, no
               approval, authorization, order or consent of any court,
               regulatory body, administrative agency or other governmental body
               is required for the execution and delivery of this Agreement or
               the Stockholders Agreement or the consummation by the Selling
               Stockholders of the transactions contemplated by this Agreement,
               except such as have been obtained and are in full force and
               effect under the Act and such as may be required under the rules
               of the NASD and applicable Blue Sky laws;

                         (14) To the best of such counsel's knowledge, the
               Selling Stockholders have full right, power and authority to
               enter into this Agreement and the Stockholders Agreement and to
               sell, transfer and deliver the Common Shares to be sold on such
               Closing Date by such Selling Stockholders hereunder and good and
               marketable title to such Common Shares so sold, free and clear of
               all liens, encumbrances, equities, claims, restrictions, security
               interests, voting trusts, or other defects of title whatsoever,
               has been transferred to the Underwriters (whom counsel may assume
               to be bona fide purchasers) who have purchased such Common Shares
               hereunder; and

                         (15) To the best of such counsel's knowledge, this
               Agreement and the Stockholders Agreement are valid and binding
               agreements of each of the Selling Stockholders in accordance with
               their terms except as enforceability may be limited by general
               equitable principles, bankruptcy, insolvency, reorganization,
               moratorium or other laws affecting creditors' rights generally
               and except with respect to those provisions relating to
               indemnities or contributions for liabilities under the Act, as to
               which no opinion need be expressed.

                         (16) No transfer taxes are required to be paid in
               connection with the sale and delivery of the Common Shares to the
               Underwriters hereunder.

               In rendering such opinion, such counsel may rely as to the
     matters set forth in paragraphs (14), (15) and

                                      26.

     (16), on opinions of other counsel retained by the Selling Stockholders, as
     to matters of local law, on opinions of local counsel, and as to matters of
     fact, on certificates of the Selling Stockholders and of officers of the
     Company and of governmental officials, in which case their opinion is to
     state that they are so doing and that the Underwriters are justified in
     relying on such opinions or certificates and copies of said opinions or
     certificates are to be attached to the opinion.  Such counsel shall also
     include a statement to the effect that nothing has come to such counsel's
     attention that would lead such counsel to believe that either at the
     effective date of the Registration Statement or at the applicable Closing
     Date the Registration Statement or the Prospectus, or any such amendment or
     supplement, contains any untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading.

                   (ii) Such opinion or opinions of Brobeck, Phleger & Harrison
          LLP, counsel for the Underwriters dated the First Closing Date or the
          Second Closing Date, as the case may be, with respect to the
          incorporation of the Company, the sufficiency of all corporate
          proceedings and other legal matters relating to this Agreement, the
          validity of the Common Shares, the Registration Statement and the
          Prospectus and other related matters as you may reasonably require,
          and the Company and the Selling Stockholders shall have furnished to
          such counsel such documents and shall have exhibited to them such
          papers and records as they may reasonably request for the purpose of
          enabling them to pass upon such matters.  In connection with such
          opinions, such counsel may rely on representations or certificates of
          officers of the Company and governmental officials.

                  (iii)  A certificate of the Company executed by the Chairman
          of the Board or President and the chief financial or accounting
          officer of the Company, dated the First Closing Date or the Second
          Closing Date, as the case may be, to the effect that:

                         (1) The representations and warranties of the Company
               set forth in Section 2 of this Agreement are true and correct as
               of the date of this Agreement and as of the First Closing Date or
               the Second Closing Date, as the case may be, and the Company has
               complied with all the agreements and satisfied all the conditions
               on its part to be performed or satisfied on or prior to such
               Closing Date;

                         (2) The Commission has not issued any order preventing
               or suspending the use of the

                                      27.
<PAGE>
 
               Prospectus or any Preliminary Prospectus filed as a part of the
               Registration Statement or any amendment thereto; no stop order
               suspending the effectiveness of the Registration Statement has
               been issued; and to the best of the knowledge of the respective
               signers, no proceedings for that purpose have been instituted or
               are pending or contemplated under the Act;

                         (3) Each of the respective signers of the certificate
               has carefully examined the Registration Statement and the
               Prospectus; in his opinion and to the best of his knowledge, the
               Registration Statement and the Prospectus and any amendments or
               supplements thereto contain all statements required to be stated
               therein regarding the Company and its subsidiaries; and neither
               the Registration Statement nor the Prospectus nor any amendment
               or supplement thereto includes any untrue statement of a material
               fact or omits to state any material fact required to be stated
               therein or necessary to make the statements therein not
               misleading;

                         (4) Since the initial date on which the Registration
               Statement was filed, no agreement, written or oral, transaction
               or event has occurred which should have been set forth in an
               amendment to the Registration Statement or in a supplement to or
               amendment of any prospectus which has not been disclosed in such
               a supplement or amendment;

                         (5) Since the respective dates as of which information
               is given in the Registration Statement and the Prospectus, and
               except as disclosed in or contemplated by the Prospectus, there
               has not been any material adverse change or a development
               involving a material adverse change in the condition (financial
               or otherwise), business, properties, results of operations,
               management or prospects of the Company and its subsidiaries; and
               no legal or governmental action, suit or proceeding is pending or
               threatened against the Company or any of its subsidiaries which
               is material to the Company and its subsidiaries, whether or not
               arising from transactions in the ordinary course of business, or
               which may adversely affect the transactions contemplated by this
               Agreement; since such dates and except as so disclosed, neither
               the Company nor any of its subsidiaries has entered into any
               verbal or written agreement or other transaction which is not in
               the ordinary course of business or which could result in a
               material reduction in the

                                      28.

               future earnings of the Company or incurred any material liability
               or obligation, direct, contingent or indirect, made any change in
               its capital stock, made any material change in its short-term
               debt or funded debt or repurchased or otherwise acquired any of
               the Company's capital stock; and the Company has not declared or
               paid any dividend, or made any other distribution, upon its
               outstanding capital stock payable to stockholders of record on a
               date prior to the First Closing Date or Second Closing Date; and

                         (6) Since the respective dates as of which information
               is given in the Registration Statement and the Prospectus and
               except as disclosed in or contemplated by the Prospectus, the
               Company and its subsidiaries have not sustained a material loss
               or damage by strike, fire, flood, windstorm, accident or other
               calamity (whether or not insured).

                    (iv) On the First Closing Date a certificate, dated such
          Closing Date and addressed to you, signed by or on behalf of each of

          correct, as if made at and as of the First Closing Date and such
          Selling Stockholder has complied with all the agreements and satisfied
          all the conditions on his part to be performed or satisfied prior to
          the First Closing Date.

          All such opinions, certificates, letters and documents shall be in
compliance with the provisions hereof only if they are satisfactory to you and
to Brobeck, Phleger & Harrison LLP, counsel for the Underwriters.  The Company
shall furnish you with such manually signed or conformed copies of such
opinions, certificates, letters and documents as you request.  Any certificate
signed by any officer of the Company and delivered to the Representatives or to
counsel for the Underwriters shall be deemed to be a representation and warranty
by the Company to the Underwriters as to the statements made therein.

          If any condition to the Underwriters' obligations hereunder to be
satisfied prior to or at the First Closing Date is not so satisfied, this
Agreement at your election will terminate upon notification by you as
Representatives to the Company and the Selling Stockholders without liability on
the part of any Underwriter, the Company or the Selling Stockholders except for
the expenses to be paid or reimbursed by the Company and by the Selling
Stockholders pursuant to Sections 7 and 9 hereof and except to the extent
provided in Section 11 hereof.

          SECTION 9.  Reimbursement of Underwriters' Expenses. Notwithstanding
                      ---------------------------------------                 
any other provisions hereof, if this Agreement shall be terminated by you
pursuant to Section 8, or if the sale to the Underwriters of the Common Shares
at the First Closing is not consummated because of any refusal, inability or
failure on the part of the Company or the Selling Stockholders to perform any
agreement herein or to comply with any provision hereof, the Company agrees to
reimburse you and the other Underwriters upon demand for all out-of-pocket
expenses that shall have been reasonably incurred by you and them in connection
with the proposed purchase and the sale of the Common Shares, including but not
limited to fees and disbursements of counsel, printing expenses, travel
expenses, postage, telegraph charges and telephone charges relating directly to
the offering contemplated by the Prospectus.  Any such termination shall be
without liability of any party to any other party except that the provisions of
this Section, Section 7 and Section 11 shall at all times be effective and shall
apply.

          SECTION 10.  Effectiveness of Registration Statement.  You, the
                       ---------------------------------------           
Company and the Selling Stockholders will use your, its and their best efforts
to cause the Registration Statement to become effective, to prevent the issuance
of any stop order suspending the effectiveness of the Registration Statement
and, if such stop order be issued, to obtain as soon as possible the lifting
thereof.

          SECTION 11.  Indemnification.
                       --------------- 

               (a) The Company and each of the Selling Stockholders, jointly and
     severally, agree to indemnify and hold harmless each Underwriter and each
     person, if any, who controls any Underwriter within the meaning of the Act

                                      31.
<PAGE>
 
     against any losses, claims, damages, liabilities or expenses, joint or
     several, to which such Underwriter or such controlling person may become
     subject, under the Act, the Exchange Act, or other federal or state
     statutory law or regulation, or at common law or otherwise (including in
     settlement of any litigation, if such settlement is effected with the
     written consent of the Company), insofar as such losses, claims, damages,
     liabilities or expenses (or actions in respect thereof as contemplated
     below) arise out of or are based upon any untrue statement or alleged
     untrue statement of any material fact contained in the Registration
     Statement, any Preliminary Prospectus, the Prospectus, or any amendment or
     supplement thereto, or arise out of or are based upon the omission or
     alleged omission to state in any of them a material fact required to be
     stated therein or necessary to make the statements in any of them not
     misleading, or arise out of or are based in whole or in part on any
     inaccuracy in the representations and warranties of the Company or the
     Selling Stockholders contained herein or any failure of the Company or the
     Selling Stockholders to perform their respective obligations hereunder or
     under law; and will reimburse each Underwriter and each such controlling
     person for any legal and other expenses as such expenses are reasonably
     incurred by such Underwriter or such controlling person in connection with
     investigating, defending, settling, compromising or paying any such loss,
     claim, damage, liability, expense or action; provided, however, that
     neither the Company nor the Selling Stockholders will be liable in any such
     case to the extent that any such loss, claim, damage, liability or expense
     arises out of or is based upon an untrue statement or alleged untrue
     statement or omission or alleged omission made in the Registration
     Statement, any Preliminary Prospectus, the Prospectus or any amendment or
     supplement thereto in reliance upon and in conformity with the information
     furnished to the Company pursuant to Section 4 hereof.  The Company and the
     Selling Stockholders may agree, as among themselves and without limiting
     the rights of the Underwriters under this Agreement, as to their respective
     amounts of such liability for which they each shall be responsible.  In
     addition to its other obligations under this Section 11(a), the Company and
     the Selling Stockholders agree that, as an interim measure during the
     pendency of any claim, action, investigation, inquiry or other proceeding
     arising out of or based upon any statement or omission, or any alleged
     statement or omission, or any inaccuracy in the representations and
     warranties of the Company or the Selling Stockholders herein or failure to
     perform its obligations hereunder, all as described in this Section 11(a),
     it will reimburse each Underwriter on a quarterly basis for all reasonable
     legal or other expenses incurred in connection with investigating or
     defending any such claim, action, investigation, inquiry or other
     proceeding, notwithstanding the absence of a judicial determination as to
     the propriety

                                      32.
<PAGE>
 
     and enforceability of the Company's or the Selling Stockholders' obligation
     to reimburse each Underwriter for such expenses and the possibility that
     such payments might later be held to have been improper by a court of
     competent jurisdiction.  To the extent that any such interim reimbursement
     payment is so held to have been improper, each Underwriter shall promptly
     return it to the Company together with interest, compounded daily,
     determined on the basis of the prime rate (or other commercial lending rate
     for borrowers of the highest credit standing) announced from time to time
     by Bank of America NT&SA, San Francisco, California (the "Prime Rate").
     Any such interim reimbursement payments which are not made to an
     Underwriter within 30 days of a request for reimbursement, shall bear
     interest at the Prime Rate from the date of such request.  This indemnity
     agreement will be in addition to any liability which the Company or the
     Selling Stockholders may otherwise have.

               (b) Each Underwriter will severally indemnify and hold harmless
     the Company, each of its directors, each of its officers who signed the
     Registration Statement, the Selling Stockholders and each person, if any,
     who controls the Company or any Selling Stockholder within the meaning of
     the Act, against any losses, claims, damages, liabilities or expenses to
     which the Company, or any such director, officer, Selling Stockholder or
     controlling person may become subject, under the Act, the Exchange Act, or
     other federal or state statutory law or regulation, or at common law or
     otherwise (including in settlement of any litigation, if such settlement is
     effected with the written consent of such Underwriter), insofar as such
     losses, claims, damages, liabilities or expenses (or actions in respect
     thereof as contemplated below) arise out of or are based upon any untrue or
     alleged untrue statement of any material fact contained in the Registration
     Statement, any Preliminary Prospectus, the Prospectus, or any amendment or
     supplement thereto, or arise out of or are based upon the omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading, in each
     case to the extent, but only to the extent, that such untrue statement or
     alleged untrue statement or omission or alleged omission was made in the
     Registration Statement, any Preliminary Prospectus, the Prospectus, or any
     amendment or supplement thereto, in reliance upon and in conformity with
     the information furnished to the Company pursuant to Section 4 hereof; and
     will reimburse the Company, or any such director, officer, Selling
     Stockholder or controlling person for any legal and other expense
     reasonably incurred by the Company, or any such director, officer, Selling
     Stockholder or controlling person in connection with investigating,
     defending, settling, compromising or paying any such loss, claim, damage,
     liability, expense or action. In addition to its

                                      33.

     other obligations under this Section 11(b), each Underwriter severally
     agrees that, as an interim measure during the pendency of any claim,
     action, investigation, inquiry or other proceeding arising out of or based
     upon any statement or omission, or any alleged statement or omission,
     described in this Section 11(b) which relates to information furnished to
     the Company pursuant to Section 4 hereof, it will reimburse the Company
     (and, to the extent applicable, each officer, director, controlling person
     or Selling Stockholder) on a quarterly basis for all reasonable legal or
     other expenses incurred in connection with investigating or defending any
     such claim, action, investigation, inquiry or other proceeding,
     notwithstanding the absence of a judicial determination as to the propriety
     and enforceability of the Underwriters' obligation to reimburse the Company
     (and, to the extent applicable, each officer, director, controlling person
     or Selling Stockholder) for such expenses and the possibility that such
     payments might later be held to have been improper by a court of competent
     jurisdiction.  To the extent that any such interim reimbursement payment is
     so held to have been improper, the Company (and, to the extent applicable,
     each officer, director, controlling person or Selling Stockholder) shall
     promptly return it to the Underwriters together with interest, compounded
     daily, determined on the basis of the Prime Rate.  Any such interim
     reimbursement payments which are not made to the Company within 30 days of
     a request for reimbursement, shall bear interest at the Prime Rate from the
     date of such request.  This indemnity agreement will be in addition to any
     liability which such Underwriter may otherwise have.

               (c) Promptly after receipt by an indemnified party under this
     Section of notice of the commencement of any action, such indemnified party
     will, if a claim in respect thereof is to be made against an indemnifying
     party under this Section, notify the indemnifying party in writing of the
     commencement thereof; but the omission so to notify the indemnifying party
     will not relieve it from any liability which it may have to any indemnified
     party for contribution or otherwise than under the indemnity agreement
     contained in this Section or to the extent it is not prejudiced as a
     proximate result of such failure.  In case any such action is brought
     against any indemnified party and such indemnified party seeks or intends
     to seek indemnity from an indemnifying party, the indemnifying party will
     be entitled to participate in, and, to the extent that it may wish, jointly
     with all other indemnifying parties similarly notified, to assume the
     defense thereof with counsel reasonably satisfactory to such indemnified
     party; provided, however, if the defendants in any such action include both
     the indemnified party and the indemnifying party and the indemnified party
     shall have reasonably concluded that there may be a conflict between the
     positions of the indemnifying

                                      34.
<PAGE>
 
     party and the indemnified party in conducting the defense of any such
     action or that there may be legal defenses available to it and/or other
     indemnified parties which are different from or additional to those
     available to the indemnifying party, the indemnified party or parties shall
     have the right to select separate counsel to assume such legal defenses and
     to otherwise participate in the defense of such action on behalf of such
     indemnified party or parties.  Upon receipt of notice from the indemnifying
     party to such indemnified party of its election so to assume the defense of
     such action and approval by the indemnified party of counsel, the
     indemnifying party will not be liable to such indemnified party under this
     Section for any legal or other expenses subsequently incurred by such
     indemnified party in connection with the defense thereof unless (i) the
     indemnified party shall have employed such counsel in connection with the
     assumption of legal defenses in accordance with the proviso to the next
     preceding sentence (it being understood, however, that the indemnifying
     party shall not be liable for the expenses of more than one separate
     counsel, approved by the Representatives in the case of paragraph (a),
     representing the indemnified parties who are parties to such action) or
     (ii) the indemnifying party shall not have employed counsel reasonably
     satisfactory to the indemnified party to represent the indemnified party
     within a reasonable time after notice of commencement of the action, in
     each of which cases the fees and expenses of counsel shall be at the
     expense of the indemnifying party.

               (d) If the indemnification provided for in this Section 11 is
     required by its terms but is for any reason held to be unavailable to or
     otherwise insufficient to hold harmless an indemnified party under
     paragraphs (a), (b) or (c) in respect of any losses, claims, damages,
     liabilities or expenses referred to herein, then each applicable
     indemnifying party shall contribute to the amount paid or payable by such
     indemnified party as a result of any losses, claims, damages, liabilities
     or expenses referred to herein (i) in such proportion as is appropriate to
     reflect the relative benefits received by the Company, the Selling
     Stockholders and the Underwriters from the offering of the Common Shares or
     (ii) if the allocation provided by clause (i) above is not permitted by
     applicable law, in such proportion as is appropriate to reflect not only
     the relative benefits referred to in clause (i) above but also the relative
     fault of the Company, the Selling Stockholders and the Underwriters in
     connection with the statements or omissions or inaccuracies in the
     representations and warranties herein which resulted in such losses,
     claims, damages, liabilities or expenses, as well as any other relevant
     equitable considerations.  The respective relative benefits received by the
     Company, the Selling Stockholders and the Underwriters shall be deemed to
     be in the same

                                      35.
<PAGE>
 
     proportion, in the case of the Company and the Selling Stockholders as the
     total price paid to the Company and to the Selling Stockholders,
     respectively, for the Common Shares sold by them to the Underwriters (net
     of underwriting commissions but before deducting expenses), and in the case
     of the Underwriters as the underwriting commissions received by them bears
     to the total of such amounts paid to the Company and to the Selling
     Stockholders and received by the Underwriters as underwriting commissions.
     The relative fault of the Company, the Selling Stockholders and the
     Underwriters shall be determined by reference to, among other things,
     whether the untrue or alleged untrue statement of a material fact or the
     omission or alleged omission to state a material fact or the inaccurate or
     the alleged inaccurate representation and/or warranty relates to
     information supplied by the Company, the Selling Stockholders or the
     Underwriters and the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission.  The amount paid or payable by a party as a result of the losses,
     claims, damages, liabilities and expenses referred to above shall be deemed
     to include, subject to the limitations set forth in subparagraph (c) of
     this Section 11, any legal or other fees or expenses reasonably incurred by
     such party in connection with investigating or defending any action or
     claim.  The provisions set forth in subparagraph (c) of this Section 11
     with respect to notice of commencement of any action shall apply if a claim
     for contribution is to be made under this subparagraph (d); provided,
     however, that no additional notice shall be required with respect to any
     action for which notice has been given under subparagraph (c) for purposes
     of indemnification.  The Company, the Selling Stockholders and the
     Underwriters agree that it would not be just and equitable if contribution
     pursuant to this Section 11 were determined solely by pro rata allocation
     (even if the Underwriters were treated as one entity for such purpose) or
     by any other method of allocation which does not take account of the
     equitable considerations referred to in this subparagraph (d).
     Notwithstanding the provisions of this Section 11, no Underwriter shall be
     required to contribute any amount in excess of the amount of the total
     underwriting commissions received by such Underwriter in connection with
     the Common Shares underwritten by it and distributed to the public.  No
     person guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Act) shall be entitled to contribution from any person
     who was not guilty of such fraudulent misrepresentation.  The Underwriters'
     obligations to contribute pursuant to this Section 11 are several in
     proportion to their respective underwriting commitments and not joint.

               (e) It is agreed that any controversy arising out of the
     operation of the interim reimbursement arrangements

                                      36.
<PAGE>
 
     set forth in Sections 11(a) and 11(b) hereof, including the amounts of any
     requested reimbursement payments and the method of determining such
     amounts, shall be settled by arbitration conducted under the provisions of
     the Constitution and Rules of the Board of Governors of the New York Stock
     Exchange, Inc. or pursuant to the Code of Arbitration Procedure of the
     NASD.  Any such arbitration must be commenced by service of a written
     demand for arbitration or written notice of intention to arbitrate, therein
     electing the arbitration tribunal.  In the event the party demanding
     arbitration does not make such designation of an arbitration tribunal in
     such demand or notice, then the party responding to said demand or notice
     is authorized to do so.  Such an arbitration would be limited to the
     operation of the interim reimbursement provisions contained in Sections
     11(a) and 11(b) hereof and would not resolve the ultimate propriety or
     enforceability of the obligation to reimburse expenses which is created by
     the provisions of such Sections 11(a) and 11(b) hereof.

          SECTION 12.  Default of Underwriters.  It shall be a condition to this
                       -----------------------                                  
Agreement and the obligation of the Company and the Selling Stockholders to sell
and deliver the Common Shares hereunder, and of each Underwriter to purchase the
Common Shares in the manner as described herein, that, except as hereinafter in
this paragraph provided, each of the Underwriters shall purchase and pay for all
the Common Shares agreed to be purchased by such Underwriter hereunder upon
tender to the Representatives of all such shares in accordance with the terms
hereof.  If any Underwriter or Underwriters default in their obligations to
purchase Common Shares hereunder on either the First or Second Closing Date and
the aggregate number of Common Shares which such defaulting Underwriter or
Underwriters agreed but failed to purchase on such Closing Date does not exceed
10% of the total number of Common Shares which the Underwriters are obligated to
purchase on such Closing Date, the non-defaulting Underwriters shall be
obligated severally, in proportion to their respective commitments hereunder, to
purchase the Common Shares which such defaulting Underwriters agreed but failed
to purchase on such Closing Date.  If any Underwriter or Underwriters so default
and the aggregate number of Common Shares with respect to which such default
occurs is more than the above percentage and arrangements satisfactory to the
Representatives and the Company for the purchase of such Common Shares by other
persons are not made within 48 hours after such default, this Agreement will
terminate without liability on the part of any non-defaulting Underwriter or the
Company or the Selling Stockholders except for the expenses to be paid by the
Company and the Selling Stockholders pursuant to Section 7 hereof and except to
the extent provided in Section 11 hereof.

          In the event that Common Shares to which a default relates are to be
purchased by the non-defaulting Underwriters or by another party or parties, the
Representatives or the Company

                                      37.
<PAGE>
 
shall have the right to postpone the First or Second Closing Date, as the case
may be, for not more than five business days in order that the necessary changes
in the Registration Statement, Prospectus and any other documents, as well as
any other arrangements, may be effected.  As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section.  Nothing herein will relieve a defaulting Underwriter from liability
for its default.

          SECTION 13.  Effective Date.  This Agreement shall become effective
                       --------------                                        
immediately as to Sections 7, 9, 11, 14 and 16 and, as to all other provisions,
(i) if at the time of execution of this Agreement the Registration Statement has
not become effective, at 2:00 P.M., California Time, on the first full business
day following the effectiveness of the Registration Statement, or (ii) if at the
time of execution of this Agreement the Registration Statement has been declared
effective, at 2:00 P.M., California Time, on the first full business day
following the date of execution of this Agreement; but this Agreement shall
nevertheless become effective at such earlier time after the Registration
Statement becomes effective as you may determine on and by notice to the Company
or by release of any of the Common Shares for sale to the public.  For the
purposes of this Section 13, the Common Shares shall be deemed to have been so
released upon the release for publication of any newspaper advertisement
relating to the Common Shares or upon the release by you of telegrams (i)
advising Underwriters that the Common Shares are released for public offering,
or (ii) offering the Common Shares for sale to securities dealers, whichever may
occur first.

          SECTION 14.  Termination.  Without limiting the right to terminate
                       -----------                                          
this Agreement pursuant to any other provision hereof:

               (a) This Agreement may be terminated by the Company by notice to
     you and the Selling Stockholders or by you by notice to the Company and the
     Selling Stockholders at any time prior to the time this Agreement shall
     become effective as to all its provisions, and any such termination shall
     be without liability on the part of the Company or the Selling Stockholders
     to any Underwriter (except for the expenses to be paid or reimbursed by the
     Company and the Selling Stockholders pursuant to Sections 7 and 9 hereof
     and except to the extent provided in Section 11 hereof) or of any
     Underwriter to the Company or the Selling Stockholders (except to the
     extent provided in Section 11 hereof).

               (b) This Agreement may also be terminated by you prior to the
     First Closing Date by notice to the Company (i) if additional material
     governmental restrictions, not in force and effect on the date hereof,
     shall have been imposed upon trading in securities generally or minimum or
     maximum prices shall have been generally established on the New York Stock
     Exchange or on the American Stock Exchange or in the

                                      38.
<PAGE>
 
     over the counter market by the NASD, or trading in securities generally
     shall have been suspended on either such Exchange or in the over the
     counter market by the NASD, or a general banking moratorium shall have been
     established by federal, New York or California authorities, (ii) if an
     outbreak of major hostilities or other national or international calamity
     or any substantial change in political, financial or economic conditions
     shall have occurred or shall have accelerated or escalated to such an
     extent, as, in the judgment of the Representatives, to affect adversely the
     marketability of the Common Shares, (iii) if any adverse event shall have
     occurred or shall exist which makes untrue or incorrect in any material
     respect any statement or information contained in the Registration
     Statement or Prospectus or which is not reflected in the Registration
     Statement or Prospectus but should be reflected therein in order to make
     the statements or information contained therein not misleading in any
     material respect, or (iv) if there shall be any action, suit or proceeding
     pending or threatened, or there shall have been any development or
     prospective development involving particularly the business or properties
     or securities of the Company or any of its subsidiaries or the transactions
     contemplated by this Agreement, which, in the reasonable judgment of the
     Representatives, may materially and adversely affect the Company's business
     or earnings and makes it impracticable or inadvisable to offer or sell the
     Common Shares.  Any termination pursuant to this subsection (b) shall be
     without liability on the part of any Underwriter to the Company or the
     Selling Stockholders or on the part of the Company or the Selling
     Stockholders to any Underwriter (except for expenses to be paid or
     reimbursed by the Company and the Selling Stockholders pursuant to Sections
     7 and 9 hereof and except to the extent provided in Section 11 hereof.

          SECTION 15.  Failure of the Selling Stockholders to Sell and Deliver.
                       -------------------------------------------------------  
If one or more of the Selling Stockholders shall fail to sell and deliver to the
Underwriters the Common Shares to be sold and delivered by such Selling
Stockholders at the First Closing Date under the terms of this Agreement, then
the Underwriters may at their option, by written notice from you to the Company
and the Selling Stockholders, either (i) terminate this Agreement without any
liability on the part of any Underwriter or, except as provided in Sections 7, 9
and 11 hereof, the Company or the Selling Stockholders, or (ii) purchase the
shares which the Company and other Selling Stockholders have agreed to sell and
deliver in accordance with the terms hereof.  In the event of a failure by one
or more of the Selling Stockholders to sell and deliver as referred to in this
Section, either you or the Company shall have the right to postpone the Closing
Date for a period not exceeding seven business days in order that the necessary
changes in the Registration Statement,

                                      39.
<PAGE>
 
Prospectus and any other documents, as well as any other arrangements, may be
effected.

          SECTION 16.  Representations and Indemnities to Survive Delivery.  The
                       ---------------------------------------------------      
respective indemnities, agreements, representa tions, warranties and other
statements of the Company, of its officers, of the Selling Stockholders and of
the several Underwriters set forth in or made pursuant to this Agreement will
remain in full force and effect, regardless of any investigation made by or on
behalf of any Underwriter or the Company or any of its or their partners,
officers or directors or any controlling person, or the Selling Stockholders, as
the case may be, and will survive delivery of and payment for the Common Shares
sold hereunder and any termination of this Agreement.

          SECTION 17.  Notices.  All communications hereunder shall be in
                       -------                                           
writing and, if sent to the Representatives shall be mailed, delivered or
telegraphed and confirmed to you at 600 Montgomery Street, San Francisco,
California 94111, Attention:  David Baylor, with a copy to Thomas A. Bevilacqua,

Selling Stockholders shall be mailed, delivered or telegraphed and confirmed to
the Company at 47370 Fremont Boulevard, Fremont, California 94538 with a copy to
Thomas C. DeFilipps, Esq. at Wilson, Sonsini, Goodrich & Rosati.  The Company,
the Selling Stockholders or you may change the address for receipt of
communications hereunder by giving notice to the others.

          SECTION 18.  Successors.  This Agreement will inure to the benefit of
                       ----------                                              
and be binding upon the parties hereto, including any substitute Underwriters
pursuant to Section 12 hereof, and to the benefit of the officers and directors
and controlling persons referred to in Section 11, and in each case their
respective successors, personal representatives and assigns, and no other person
will have any right or obligation hereunder.  No such assignment shall relieve
any party of its obligations hereunder.  The term "successors" shall not include
any purchaser of the Common Shares as such from any of the Underwriters merely
by reason of such purchase.

          SECTION 19.  Representation of Underwriters.  You will act as
                       ------------------------------                  
Representatives for the several Underwriters in connection with all dealings
hereunder, and any action under or in respect of this Agreement taken jointly or
by Montgomery Securities, as Representatives, will be binding upon all the
Underwriters.

          SECTION 20.  Partial Unenforceability.  The invalidity or
                       ------------------------                    
unenforceability of any Section, paragraph or provision of this Agreement shall
not affect the validity or enforceability of any other Section, paragraph or
provision hereof.  If any Section, paragraph or provision of this Agreement is
for any reason determined to be invalid or unenforceable, there shall be

                                      40.
<PAGE>
 
deemed to be made such minor changes (and only such minor changes) as are
necessary to make it valid and enforceable.

          SECTION 21.  Applicable Law.  This Agreement shall be governed by and
                       --------------                                          
construed in accordance with the internal laws (and not the laws pertaining to
conflicts of laws) of the State of California.

          SECTION 22.  General.  This Agreement constitutes the entire agreement
                       -------                                                  
of the parties to this Agreement and supersedes all prior written or oral and
all contemporaneous oral agreements, understandings and negotiations with
respect to the subject matter hereof.  This Agreement may be executed in several
counterparts, each one of which shall be an original, and all of which shall
constitute one and the same document.

          In this Agreement, the masculine, feminine and neuter genders and the
singular and the plural include one another.  The section headings in this
Agreement are for the convenience of the parties only and will not affect the
construction or interpretation of this Agreement.  This Agreement may be amended
or modified, and the observance of any term of this Agreement may be waived,
only by a writing signed by the Company, the Selling Stockholders and you.

          Any person executing and delivering this Agreement as Attorney-in-fact
for the Selling Stockholders represents by so doing that such Attorney-in-fact
has been duly appointed as Attorney-in-fact by such Selling Stockholder pursuant
to a validly existing and binding Power of Attorney which authorizes such
Attorney-in-fact to take such action.  Any action taken under this Agreement by
any of the Attorneys-in-fact will be binding on all the Selling Stockholders.

                                      II.

     The purpose of the Company is to engage in any lawful act or activity for
which a corporation may be organized under the General Corporation Law of
California other than the banking business, the trust company business or the
practice of a profession permitted to be incorporated by the California
Corporations Code.

                                      III.

     The Company is authorized to issue two classes of stock, designated "Common
Stock" and "Preferred Stock".  The total number of shares which the Company is
authorized to issue is 17,625,000. The number of shares of Common Stock which
the Company is authorized to issue is 15,000,000.  The number of shares of
Preferred Stock which the Company is authorized to issue is 2,625,000, all of
which is designated as Series 1 Preferred Stock.

     The Series 1 Preferred Stock shall have the rights, preferences, privileges
and restrictions set forth below.

     Section 1.  General Definitions.  For purposes of these Restated Articles
                 -------------------                                          
of Incorporation, the following definitions shall apply:

          (a)  "Preferred" or "Series 1 Preferred" shall refer to the Series 1
               -----------------------------------                            
Preferred Stock.

          (b)  "Common" shall mean the Company's Common Stock.
               --------

          (c)  "Subsidiary" shall mean any corporation at least 50% of whose
               ------------

more of such subsidiaries.

          (d)  "Board" shall mean the Board of Directors of the Company.

available therefor, prior and in preference to any declaration or payment of any
dividend (payable other than in Common Stock or other securities and rights
convertible into or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock of the Company) on the Common
Stock at the rate of $0.19 per share of Series 1 Preferred, per annum, payable
when, as and if declared by the Board of Directors.  After payment of such
dividends, any additional dividends declared shall be distributed among the
holders of Common Stock and Series 1 Preferred ratably on a share-for-share
basis (with all Preferred participating in such distribution based upon the
number of shares of Common into which each share of Preferred is then
convertible).  The right to dividends shall not be cumulative, and no right
shall accrue to holders of any shares by reason of the fact that dividends on
such shares are not declared or paid in any prior year.

     Section 3.  Liquidation, Merger, Consolidation.
                 ---------------------------------- 

          (a)  At any time, in the event of any of the following occurrences (a
"Transaction"):

               (i) any transaction or series of related transactions (including,
without limitation, any reorganization, merger or consolidation) which will
result in the Company's shareholders immediately prior to such transaction not
holding (by virtue of such shares or securities issued solely with respect
thereto) at least 50% of the voting power of the surviving or continuing entity;

               (ii) a sale of all or substantially all of the assets of the
Company, unless the Company's shareholders immediately prior to such sale will,
as a result of such sale, hold (by virtue of securities issued as consideration
for the Company's sale) at least 50% of the voting power of the purchasing
entity; or

               (iii) any liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary;

then the Company shall take appropriate steps in connection with such
Transaction to ensure that the assets of the Company available for distribution
or such other property issued in connection with such Transaction shall be
distributed at the closing of the Transaction in the order and priority that
follows:

                    (A) the holders of the Series 1 Preferred shall receive, for
each share of such stock then held, property or cash in an amount equal to the
sum of (A) $2.75 per share of Series 1 Preferred (appropriately adjusted for
stock splits, reverse stock splits and the like) plus (B) all declared but
unpaid dividends on each such share; then

                                      -2-
<PAGE>
 
                    (B) property and/or cash shall next be distributed (1) 50%
among the holders of Series 1 Preferred and (2) 50% among the holders of the
Common until the holders of the Series 1 Preferred have received, for each share
of Series 1 Preferred held, property or cash in an amount which, when combined
with the property and/or cash received pursuant to paragraph (A) above, equals
$6.875 (appropriately adjusted for any stock splits, reverse stock splits and
the like); then

                    (C) property and/or cash shall next be distributed among the
holders of the Common until the holders of the Common have received, for each
share of Common held, property or cash in an amount which, when combined with
the property and/or cash received pursuant to paragraph (B) above, equals $6.875
(appropriately adjusted for stock splits, reverse stock splits and the like);
then

                    (D) all remaining assets available for distribution shall be
distributed among the holders of the Common and the Series 1 Preferred on a
share-for-share basis, with the holders of the Series 1 Preferred sharing on an
as converted basis.

          (b)  Any securities to be delivered to the shareholders pursuant to
subsection 3(a) above shall be valued as follows:

               (i) If traded on a securities exchange or the National Market
System of the National Association of Securities Dealers, Inc., the value shall
be deemed to be the average of the closing prices of the securities on such
exchange over the 30 day period ending three (3) days prior to the closing;

               (ii) If actively traded over the counter, the value shall be
deemed to be the average of the closing bid or sale prices (whichever are
applicable) over the 30 day period ending three (3) days prior to the closing;
and

               (iii) If there is no active public market, the value shall be the
fair market value thereof, as mutually determined by the Board and the holders
of a majority of the then outstanding shares of Series 1 Preferred or, if they
are unable to agree, by an independent appraiser mutually acceptable to the
Board and to such holders.

     Section 4.  Conversion.  The holders of the Preferred shall have conversion
                 ----------                                                     
rights as follows:

          (a)  Right to Convert.  Each share of Series 1 Preferred shall be
               ----------------                                            
convertible, at the option of the holder thereof, at any time, into such number
of fully paid and nonassessable shares of Common as is determined by dividing
$2.75 by the then applicable Series 1 Conversion Price, determined as
hereinafter provided, in effect at the time of conversion.  The price at which
shares of Common shall be deliverable upon conversion (the "Series 1 Conversion
Price") shall initially be $2.75 per share of Common.  Such initial Series 1
Conversion Price shall be subject to adjustment as hereinafter provided.

                                      -3-
<PAGE>
 
          (b)  Automatic Conversion.  Each share of Preferred shall 
               --------------------
automatically be converted into Common at the then applicable conversion rate
upon the earlier of (i) immediately prior to the closing of a firm commitment
underwritten public offering pursuant to an effective registration statement
under the Securities Act of 1933, as amended, covering the offer and sale of
Common for the account of the Company to the public at a price per share
(determined without regard to underwriter commissions and expenses) of not less
than $6.875 (appropriately adjusted for stock splits, reverse stock splits and
the like) and an aggregate gross offering price of not less than $10,000,000 or
(ii) the election by holders of at least 50% of the outstanding Preferred to so
convert. In the event of such an offering as described in subsection (i) above,
the person(s) entitled to receive the Common issuable upon such conversion of
the Preferred shall not be deemed to have converted such Preferred until
immediately prior to the closing of such underwritten public offering.

          (c)  Mechanics of Conversion.  No fractional shares of Common shall be
               -----------------------                                          
issued upon conversion of the Preferred.  In lieu of any fractional share to
which a holder would otherwise be entitled, the Company shall pay cash equal to
such fraction multiplied by the then fair market value of a share of Common.
Before any holder of the Preferred shall be entitled to convert the same into
full shares of Common, he or she shall surrender the certificate or certificates
therefor, duly endorsed, at the office of the Company or of any transfer agent
for the Preferred; provided, however, that in the event of an automatic
conversion pursuant to Section 4(b), the outstanding shares of Preferred 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 Company or its transfer agent, and provided further that the
Company shall not be obligated to issue certificates evidencing the shares of
Common Stock issuable upon such automatic conversion unless the certificates
evidencing such shares of Preferred are either delivered to the Company or its
transfer agent as provided above, or the holder notifies the Company or its
transfer agent that such certificates have been lost, stolen or destroyed and
executes an agreement satisfactory to the Company to indemnify the Company from
any loss incurred by it in connection with such certificates.  The Company
shall, as soon as practicable thereafter, issue and deliver at such office to
such holder of the Preferred, a certificate or certificates for the number of
shares of Common to which he shall be entitled as aforesaid and a check payable
to the holder in the amount of any cash amounts payable as the result of a
conversion into a fractional share of Common, and any declared but unpaid
dividends on the converted Preferred.  Such conversion shall be deemed to have
been made immediately prior to the close of business on the date of such
surrender of the shares of Preferred to be converted, and the person or persons
entitled to receive the shares of Common issuable upon such conversion shall be
treated for all purposes as the record holder or holders of such shares of
Common on such date.

Additional Shares of Common Stock shall mean the price per share obtained by

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

Convertible Securities or shall fix a record date for 

                                      -5-
<PAGE>
 
the determination of holders of any class of securities entitled to receive any
such Options or Convertible Securities, then the maximum number of shares (as
set forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue of Options or Convertible Securities or, in case such a
record date shall have been fixed, as of the close of business on such record
date, provided that Additional Shares of Common Stock shall not be deemed to
have been issued unless the consideration per share (determined pursuant to
Section 4(d)(i)(E) hereof) of such Additional Shares of Common Stock would be
less than the Conversion Price in effect on the date of and immediately prior to
such issue, or such record date, as the case may be, and provided further that
in any such case in which Additional Shares of Common Stock are deemed to be
issued:

                              (aa) no further adjustment in the Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                              (bb) upon the expiration of any such Options or
any rights of conversion or exchange under such Convertible Securities which
shall not have been exercised, the Conversion Price computed upon the original
issue thereof (or upon the occurrence of a record date with respect thereto),
and any subsequent adjustments based thereon, shall, upon such expiration, be
recomputed as if:

                                   (I) in the case of Convertible Securities or
Options for Common Stock, the only Additional Shares of Common Stock issued were
shares of Common Stock, if any, actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities and the
consideration received therefor was the consideration actually received by the
Company for the issue of all such Options, whether or not exercised, plus the
consideration actually received by the Company upon such exercise, or for the
issue of all such Convertible Securities which were actually converted or
exchanged, plus the additional consideration, if any, actually received by the
Company upon such conversion or exchange, and

                                   (II) in the case of Options for Convertible
Securities, only the Convertible Securities, if any, actually issued upon the
exercise thereof were issued at the time of issue of such Options, and the
consideration received by the Company for the Additional Shares of Common Stock
deemed to have been then issued was the consideration actually received by the
Company for the issue of all such Options, whether or not exercised, plus the
consideration deemed to have been received by the Company upon the issue of the
Convertible Securities with respect to which such Options were actually
exercised;

                              (cc) no readjustment pursuant to clause (bb) above
shall have the effect of increasing the Conversion Price to an amount which
exceeds the lower of (i) the Conversion Price on the original adjustment date,
or (ii) the Conversion Price that would have

                                      -6-
<PAGE>
 
resulted from any issuance of Additional Shares of Common Stock between the
original adjustment date and such readjustment date; and

                              (dd) in the case of any Options which expire by
their terms not more than 30 days after the date of issue thereof, no adjustment
of the Conversion Price shall be made until the expiration or exercise of all
such Options.

                    (D)  Adjustment of Conversion Price Upon Issuance of 
                         -----------------------------------------------
Additional Shares of Common Stock.  In the event the Company shall after the 
- ---------------------------------
Original Issue Date issue Additional Shares of Common Stock (including
Additional Shares of Common Stock deemed to be issued pursuant to Section
4(d)(i)(C)) without consideration or for a consideration per share less than the
Conversion Price in effect on the date of and immediately prior to such issue,
then and in such event such Conversion Price shall be reduced, concurrently with
such issue, to a price (calculated to the nearest cent) determined by
multiplying such Conversion Price by a fraction, the numerator of which shall be
the number of shares of Common Stock outstanding immediately prior to such issue
plus the number of shares of Common Stock which the aggregate consideration
received by the Company for the total number of Additional Shares of Common
Stock so issued would purchase at such Conversion Price, and the denominator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such issue plus the number of such Additional Shares of Common Stock so
issued; and provided further that, for the purposes of this Section 4(d)(i)(D),
all shares of Common Stock issuable upon conversion of outstanding Options and
Convertible Securities shall be deemed to be outstanding, and immediately after
any Additional Shares of Common Stock are deemed issued pursuant to Section
4(d)(i)(C), such Additional Shares of Common Stock shall be deemed to be
outstanding.

                    (E)  Determination of Consideration.  For purposes of this 
                         ------------------------------ 
Section 4(d), the consideration received by the Company for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                         (1)  Cash and Property:  Such consideration shall:
                              -----------------                            

                              (aa) insofar as it consists of cash, be computed
at the aggregate amount of cash received by the Company excluding amounts paid
or payable for accrued interest or accrued dividends;

                              (bb) insofar as it consists of services or
property other than cash, be computed at the fair value thereof at the time of
such issue, as determined in good faith by the Board; and

                              (cc) in the event Additional Shares of Common
Stock are issued together with other shares or securities or other assets of the
Company for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (aa) and (bb) above,
as determined in good faith by the Board.

                         (2)  Options and Convertible Securities.  The 
                              ---------------------------------- 
consideration per share received by the Company for Additional Shares of Common
Stock deemed to have been issued pursuant to Section 4(d)(i)(C), relating to
Options and Convertible Securities, shall be determined by dividing

                              (aa) the total amount, if any, received or
receivable by the Company as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration) payable to the Company upon the exercise in full of such Options
or the conversion or exchange in full of such Convertible Securities, or in the
case of Options for Convertible Securities, the exercise in full of such Options
for Convertible Securities and the conversion or exchange in full of such
Convertible Securities, by

                              (bb) the maximum number of shares of Common Stock
(as set forth in the instruments relating thereto, without regard to any
provision contained therein for a subsequent adjustment of such number) issuable
upon the exercise in full of such Options or the conversion or exchange in full
of such Convertible Securities.

               (ii) Adjustments for Subdivisions, Combinations or Consolidations
                    ------------------------------------------------------------
of Common Stock. In the event the outstanding shares of Common Stock shall be
- ---------------                                                              
subdivided (by stock split, stock dividend or otherwise), into a greater number
of shares of Common Stock, the Conversion Price then in effect shall,
concurrently with the effectiveness of such subdivision, be proportionately
decreased (to the nearest whole cent).  In the event the outstanding shares of
Common Stock shall be combined or consolidated, by reclassification or
otherwise, into a lesser number of shares of Common Stock, the Conversion Price
then in effect shall, concurrently with the effectiveness of such combination or
consolidation, be proportionately increased (to the nearest whole cent).

               (iii) Adjustments for Other Distributions.  In the event the 
                     -----------------------------------     
Company at any time or from time to time makes, or fixes a record date for the
determination of holders of Common Stock entitled to receive, any distribution
payable in securities of the Company other than shares of Common Stock and other
than as otherwise adjusted in this Section 4, then and in each such event
provision shall be made so that the holders of Preferred shall receive upon
conversion thereof, in addition to the number of shares of Common Stock
receivable thereupon, the amount of securities of the Company which they would
have received had their shares of Preferred been converted into Common Stock on
the date of such event and had they thereafter, during the period from the date
of such event to and including the date of conversion, retained such securities
receivable by them as aforesaid during such period, subject to all other
adjustments called for during such period under this Section 4 with respect to
the rights of the holders of the Preferred.

               (iv) Adjustments for Reclassification, Exchange and Substitution.
                    ----------------------------------------------------------- 
If the Common Stock issuable upon conversion of the Preferred shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification or otherwise (other
than a subdivision, combination or consolidation of shares provided for above),
the

                                      -8-
<PAGE>
 
Conversion Price then in effect shall, concurrently with the effectiveness of
such reorganization or reclassification, be proportionately adjusted such that
the Preferred shall be convertible into, in lieu of the number of shares of
Common Stock which the holders would otherwise have been entitled to receive, a
number of shares of such other class or classes of stock equivalent to the
number of shares of Common Stock that would have been subject to receipt by the
holders upon conversion of such shares of Preferred immediately before that
change.

          (e)  No Impairment.  The Company will not, by amendment of its 
               ------------- 
Articles of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Company but will at all
times in good faith assist in the carrying out of all the provisions of this
Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the applicable conversion rights of the holders
of the Preferred, as set forth in this Section 4, against impairment.

          (f)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------                              
adjustment or readjustment of the Conversion Price or pursuant to this Section
4, the Company at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
such series of Preferred a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based.  The Company shall, upon the written request at any time
of any holder of Preferred, furnish or cause to be furnished to such holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
applicable Conversion Price for such series of Preferred at the time in effect,
and (iii) the number of shares of Common and the amount, if any, of other
property which at the time would be received upon the conversion of such series
of Preferred.

          (g)  Notices of Record Date.  In the event of any taking by the 
               ---------------------- 
Company of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend (other
than a cash dividend) or other distribution, any security or right convertible
into or entitling the holder thereof to receive additional shares of Common, or
any right to subscribe for, purchase or otherwise acquire any shares of stock of
any class or any other securities or property, or to receive any other right,
the Company shall mail to each holder of Preferred, at least 20 days prior to
the date specified therein, a notice specifying the date on which any such
record is to be taken for the purpose of such dividend, distribution, security
or right, and the amount and character of such dividend, distribution, security
or right.

          (h)  Issue Taxes.  The Company shall pay any and all issue taxes and 
               -----------                                                     
other taxes that may be payable in respect of any issue or delivery of shares of
Common on conversion of shares of Preferred pursuant hereto; provided, however,
that the Company shall not be obligated to pay any transfer taxes resulting from
any transfer requested by any holder in connection with any such conversion.

          (i)  Notices.  Any notice required by the provisions of this 
               -------

     The Preferred Stock may be issued from time to time in one or more series.
The Board of Directors is authorized to fix the number of shares of any series

to Section 5 herein, the Board of Directors is also authorized, except as to
matters fixed as to Preferred Stock in this Article Fourth, to determine and

upon any wholly unissued series of Preferred Stock and to increase or decrease
(but not below the number of shares of such series then outstanding) the number
of shares of any series subsequent to the issue of shares of that series.
Subject to Section 5 herein, in case the number of shares of any series shall be

number of shares of such series.  The rights, preferences, privileges and

     1.   General Definitions.  For purposes of these Restated Articles of
          -------------------                                             
Incorporation, the following definitions shall apply:

          (a)  "Preferred" or "Series 1 Preferred" shall refer to the Series 1
               -----------------------------------                            
Preferred Stock.

          (b)  "Common" shall mean the Company's Common Stock.
               --------                                       
<PAGE>
 
          (c)  "Subsidiary" shall mean any corporation at least 50% of whose
               ------------                                                 
outstanding voting shares shall at the time be owned by the Company or by one or

               -------                                                  

     2.   Dividend Provisions.  The holders of shares of the Series 1 Preferred
          -------------------                                                  
shall be entitled to receive dividends, out of any assets legally available
therefor, prior and in preference to any declaration or payment of any dividend

additional shares of Common Stock of the Company) on the Common Stock at the
rate of $0.19 per share of Series 1 Preferred, per annum, payable when, as and
if declared by the Board of Directors.  After payment of such dividends, any
additional dividends declared shall be distributed among the holders of Common
Stock and Series 1 Preferred ratably on a share-for-share basis (with all
Preferred participating in such distribution based upon the number of shares of
Common into which each share of Preferred is then convertible).  The right to
dividends shall not be cumulative, and no right shall accrue to holders of any
shares by reason of the fact that dividends on such shares are not declared or
paid in any prior year.

     3.   Liquidation, Merger, Consolidation.
          ---------------------------------- 

          (a)  At any time, in the event of any of the following occurrences (a
"Transaction"):

               (i)  any transaction or series of related transactions
(including, without limitation, any reorganization, merger or consolidation)
which will result in the Company's shareholders immediately prior to such
transaction not holding (by virtue of such shares or securities issued solely
with respect thereto) at least 50% of the voting power of the surviving or
continuing entity;

               (ii) a sale of all or substantially all of the assets of the
Company, unless the Company's shareholders immediately prior to such sale will,
as a result of such sale, hold (by virtue of securities issued as consideration
for the Company's sale) at least 50% of the voting power of the purchasing
entity; or

               (iii) any liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary;

then the Company shall take appropriate steps in connection with such
Transaction to ensure that the assets of the Company available for distribution
or such other property issued in connection with such Transaction shall be
distributed at the closing of the Transaction in the order and priority that
follows:

                    (A)  the holders of the Series 1 Preferred shall receive,
for each share of such stock then held, property or cash in an amount equal to
the sum of (A) $2.75 per share of

                                      -2-
<PAGE>
 
Series 1 Preferred (appropriately adjusted for stock splits, reverse stock
splits and the like) plus (B) all declared but unpaid dividends on each such
share; then

                    (B)  property and/or cash shall next be distributed (1) 50%
among the holders of Series 1 Preferred and (2) 50% among the holders of the
Common until the holders of the Series 1 Preferred have received, for each share
of Series 1 Preferred held, property or cash in an amount which, when combined
with the property and/or cash received pursuant to paragraph (A) above, equals
$6.875 (appropriately adjusted for any stock splits, reverse stock splits and
the like); then

                    (C)  property and/or cash shall next be distributed among
the holders of the Common until the holders of the Common have received, for
each share of Common held, property or cash in an amount which, when combined
with the property and/or cash received pursuant to paragraph (B) above, equals
$6.875 (appropriately adjusted for stock splits, reverse stock splits and the
like); then

                    (D)  all remaining assets available for distribution shall
be distributed among the holders of the Common and the Series 1 Preferred on a
share-for-share basis, with the holders of the Series 1 Preferred sharing on an
as converted basis.

          (b)  Any securities to be delivered to the shareholders pursuant to
subsection 3(a) above shall be valued as follows:

               (i)  If traded on a securities exchange or the National Market
System of the National Association of Securities Dealers, Inc., the value shall
be deemed to be the average of the closing prices of the securities on such
exchange over the 30 day period ending three (3) days prior to the closing;

               (ii) If actively traded over the counter, the value shall be
deemed to be the average of the closing bid or sale prices (whichever are
applicable) over the 30 day period ending three (3) days prior to the closing;
and

               (iii) If there is no active public market, the value shall be the
fair market value thereof, as mutually determined by the Board and the holders
of a majority of the then outstanding shares of Series 1 Preferred or, if they
are unable to agree, by an independent appraiser mutually acceptable to the
Board and to such holders.

     4.   Conversion.  The holders of the Preferred shall have conversion rights
          ----------                                                            
as follows:

          (a)  Right to Convert.  Each share of Series 1 Preferred shall be
               ----------------                                            
convertible, at the option of the holder thereof, at any time, into such number
of fully paid and nonassessable shares of Common as is determined by dividing
$2.75 by the then applicable Series 1 Conversion Price, determined as
hereinafter provided, in effect at the time of conversion.  The price at which
shares 

                                      -3-
<PAGE>
 
of Common shall be deliverable upon conversion (the "Series 1 Conversion Price")
shall initially be $2.75 per share of Common. Such initial Series 1 Conversion
Price shall be subject to adjustment as hereinafter provided.

          (b)  Automatic Conversion.  Each share of Preferred shall 
               --------------------
automatically be converted into Common at the then applicable conversion rate

effective registration statement under the Securities Act of 1933, as amended,
covering the offer and sale of Common for the account of the Company to the
public at a price per share (determined without regard to underwriter
commissions and expenses) of not less than $6.875 (appropriately adjusted for
stock splits, reverse stock splits and the like) and an aggregate gross offering
price of not less than $10,000,000 or (ii) the election by holders of at least
50% of the outstanding Preferred to so convert. In the event of such an offering
as described in subsection (i) above, the person(s) entitled to receive the
Common issuable upon such conversion of the Preferred shall not be deemed to
have converted such Preferred until immediately prior to the closing of such
underwritten Qualified Public Offering (as defined below).

          (c)  Mechanics of Conversion.  No fractional shares of Common shall be
               -----------------------                                          
issued upon conversion of the Preferred.  In lieu of any fractional share to
which a holder would otherwise be entitled, the Company shall pay cash equal to
such fraction multiplied by the then fair market value of a share of Common.
Before any holder of the Preferred shall be entitled to convert the same into
full shares of Common, he or she shall surrender the certificate or certificates
therefor, duly endorsed, at the office of the Company or of any transfer agent
for the Preferred; provided, however, that in the event of an automatic
conversion pursuant to Section 4(b), the outstanding shares of Preferred 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 Company or its transfer agent, and provided further that the
Company shall not be obligated to issue certificates evidencing the shares of
Common Stock issuable upon such automatic conversion unless the certificates
evidencing such shares of Preferred are either delivered to the Company or its
transfer agent as provided above, or the holder notifies the Company or its
transfer agent that such certificates have been lost, stolen or destroyed and
executes an agreement satisfactory to the Company to indemnify the Company from
any loss incurred by it in connection with such certificates.  The Company
shall, as soon as practicable thereafter, issue and deliver at such office to
such holder of the Preferred, a certificate or certificates for the number of
shares of Common to which he shall be entitled as aforesaid and a check payable
to the holder in the amount of any cash amounts payable as the result of a
conversion into a fractional share of Common, and any declared but unpaid
dividends on the converted Preferred.  Such conversion shall be deemed to have
been made immediately prior to the close of business on the date of such
surrender of the shares of Preferred to be converted, and the person or persons
entitled to receive the shares of Common issuable upon such conversion shall be
treated for all purposes as the record holder or holders of such shares of
Common on such date.

                    (C)  Deemed Issue of Additional Shares of Common Stock.
                         ------------------------------------------------- 

                         (1)  Options and Convertible Securities.  Except as 
                              ----------------------------------
otherwise provided in Section 4(d)(i)(B), in the event the Company at any time
or from time to time after the Original Issue Date shall issue any Options or
Convertible Securities or shall fix a record date for the determination of
holders of any class of securities entitled to receive any such Options or
Convertible Securities, then the maximum number of shares (as set forth in the
instrument relating thereto without regard to any provisions contained therein
for a subsequent adjustment of such number) of Common Stock issuable upon the
exercise of such Options or, in the case of Convertible Securities and Options
therefor, the conversion or exchange of such Convertible Securities, shall be
deemed to be Additional Shares of Common Stock issued as of the time of such
issue of Options or Convertible Securities or, in case such a record date shall
have been fixed, as of the close of business on such record date, provided that
Additional Shares of Common Stock shall not be deemed to have been issued unless
the consideration per share (determined pursuant to Section 4(d)(i)(E) hereof)
of such Additional Shares of Common Stock would be less than the Conversion
Price in effect on the date of and immediately prior to such issue, or such
record date, as the case may be, and provided further that in any such case in
which Additional Shares of Common Stock are deemed to be issued:

                              (aa) no further adjustment in the Conversion Price
shall be made upon the subsequent issue of Convertible Securities or shares of
Common Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                              (bb) upon the expiration of any such Options or
any rights of conversion or exchange under such Convertible Securities which
shall not have been exercised, the Conversion Price computed upon the original
issue thereof (or upon the occurrence of a record date with respect thereto),
and any subsequent adjustments based thereon, shall, upon such expiration, be
recomputed as if:

                                   (I) in the case of Convertible Securities or
Options for Common Stock, the only Additional Shares of Common Stock issued were
shares of Common Stock, if any, actually issued upon the exercise of such
Options or the conversion or exchange of such Convertible Securities and the
consideration received therefor was the consideration actually received by the
Company for the issue of all such Options, whether or not exercised, plus the
consideration actually received by the Company upon such exercise, or for the
issue of all such Convertible Securities which were actually converted or
exchanged, plus the additional consideration, if any, actually received by the
Company upon such conversion or exchange, and

                                   (II) in the case of Options for Convertible
Securities, only the Convertible Securities, if any, actually issued upon the
exercise thereof were issued at the time of issue of such Options, and the
consideration received by the Company for the Additional Shares of Common Stock
deemed to have been then issued was the consideration actually received by the
Company for the issue of all such Options, whether or not exercised, plus the
consideration 

                                      -6-
<PAGE>
 
deemed to have been received by the Company upon the issue of the Convertible
Securities with respect to which such Options were actually exercised;

                              (cc) no readjustment pursuant to clause (bb) above
shall have the effect of increasing the Conversion Price to an amount which
exceeds the lower of (i) the Conversion Price on the original adjustment date,
or (ii) the Conversion Price that would have resulted from any issuance of
Additional Shares of Common Stock between the original adjustment date and such
readjustment date; and

                              (dd) in the case of any Options which expire by
their terms not more than 30 days after the date of issue thereof, no adjustment
of the Conversion Price shall be made until the expiration or exercise of all
such Options.

                    (D)  Adjustment of Conversion Price Upon Issuance of 
                         -----------------------------------------------
Additional Shares of Common Stock.  In the event the Company shall after the 
- ---------------------------------                                        
Original Issue Date issue Additional Shares of Common Stock (including
Additional Shares of Common Stock deemed to be issued pursuant to Section
4(d)(i)(C)) without consideration or for a consideration per share less than the
Conversion Price in effect on the date of and immediately prior to such issue,
then and in such event such Conversion Price shall be reduced, concurrently with
such issue, to a price (calculated to the nearest cent) determined by
multiplying such Conversion Price by a fraction, the numerator of which shall be
the number of shares of Common Stock outstanding immediately prior to such issue
plus the number of shares of Common Stock which the aggregate consideration
received by the Company for the total number of Additional Shares of Common
Stock so issued would purchase at such Conversion Price, and the denominator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such issue plus the number of such Additional Shares of Common Stock so
issued; and provided further that, for the purposes of this Section 4(d)(i)(D),
all shares of Common Stock issuable upon conversion of outstanding Options and
Convertible Securities shall be deemed to be outstanding, and immediately after
any Additional Shares of Common Stock are deemed issued pursuant to Section
4(d)(i)(C), such Additional Shares of Common Stock shall be deemed to be
outstanding.

                    (E)  Determination of Consideration.  For purposes of this 
                         ------------------------------   
Section 4(d), the consideration received by the Company for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                         (1)  Cash and Property:  Such consideration shall:
                              -----------------                            

                              (aa) insofar as it consists of cash, be computed
at the aggregate amount of cash received by the Company excluding amounts paid
or payable for accrued interest or accrued dividends;

                                      -7-
<PAGE>
 
                              (bb) insofar as it consists of services or
property other than cash, be computed at the fair value thereof at the time of
such issue, as determined in good faith by the Board; and

                              (cc) in the event Additional Shares of Common
Stock are issued together with other shares or securities or other assets of the
Company for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (aa) and (bb) above,
as determined in good faith by the Board.

                         (2)  Options and Convertible Securities.  The 
                              ----------------------------------  
consideration per share received by the Company for Additional Shares of Common
Stock deemed to have been issued pursuant to Section 4(d)(i)(C), relating to
Options and Convertible Securities, shall be determined by dividing

                              (aa) the total amount, if any, received or
receivable by the Company as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration) payable to the Company upon the exercise in full of such Options
or the conversion or exchange in full of such Convertible Securities, or in the
case of Options for Convertible Securities, the exercise in full of such Options
for Convertible Securities and the conversion or exchange in full of such
Convertible Securities, by

                              (bb) the maximum number of shares of Common Stock
(as set forth in the instruments relating thereto, without regard to any
provision contained therein for a subsequent adjustment of such number) issuable
upon the exercise in full of such Options or the conversion or exchange in full
of such Convertible Securities.

               (ii) Adjustments for Subdivisions, Combinations or Consolidations
                    ------------------------------------------------------------
of Common Stock. In the event the outstanding shares of Common Stock shall be
- ---------------                                                              
subdivided (by stock split, stock dividend or otherwise), into a greater number
of shares of Common Stock, the Conversion Price then in effect shall,
concurrently with the effectiveness of such subdivision, be proportionately
decreased (to the nearest whole cent).  In the event the outstanding shares of
Common Stock shall be combined or consolidated, by reclassification or
otherwise, into a lesser number of shares of Common Stock, the Conversion Price
then in effect shall, concurrently with the effectiveness of such combination or
consolidation, be proportionately increased (to the nearest whole cent).

               (iii) Adjustments for Other Distributions.  In the event the 
                     ----------------------------------- 
Company at any time or from time to time makes, or fixes a record date for the
determination of holders of Common Stock entitled to receive, any distribution
payable in securities of the Company other than shares of Common Stock and other
than as otherwise adjusted in this Section 4, then and in each such event
provision shall be made so that the holders of Preferred shall receive upon
conversion thereof, in addition to the number of shares of Common Stock
receivable thereupon, the amount of securities 

                                      -8-
<PAGE>
 
of the Company which they would have received had their shares of Preferred been
converted into Common Stock on the date of such event and had they thereafter,
during the period from the date of such event to and including the date of
conversion, retained such securities receivable by them as aforesaid during such
period, subject to all other adjustments called for during such period under
this Section 4 with respect to the rights of the holders of the Preferred.

               (iv) Adjustments for Reclassification, Exchange and Substitution.
                    -----------------------------------------------------------
If the Common Stock issuable upon conversion of the Preferred shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification or otherwise (other
than a subdivision, combination or consolidation of shares provided for above),
the Conversion Price then in effect shall, concurrently with the effectiveness
of such reorganization or reclassification, be proportionately adjusted such
that the Preferred shall be convertible into, in lieu of the number of shares of
Common Stock which the holders would otherwise have been entitled to receive, a
number of shares of such other class or classes of stock equivalent to the
number of shares of Common Stock that would have been subject to receipt by the
holders upon conversion of such shares of Preferred immediately before that
change.

          (e)  No Impairment.  The Company will not, by amendment of its 
               -------------    
Articles of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Company but will at all
times in good faith assist in the carrying out of all the provisions of this
Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the applicable conversion rights of the holders
of the Preferred, as set forth in this Section 4, against impairment.

          (f)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------                              
adjustment or readjustment of the Conversion Price or pursuant to this Section
4, the Company at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
such series of Preferred a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based.  The Company shall, upon the written request at any time
of any holder of Preferred, furnish or cause to be furnished to such holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
applicable Conversion Price for such series of Preferred at the time in effect,
and (iii) the number of shares of Common and the amount, if any, of other
property which at the time would be received upon the conversion of such series
of Preferred.

          (g)  Notices of Record Date.  In the event of any taking by the 
               ----------------------     
Company of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend (other
than a cash dividend) or other distribution, any security or right convertible
into or entitling the holder thereof to receive additional shares of Common, or
any right to subscribe for, purchase or otherwise acquire any shares of stock of
any class or any other 

                                      -9-
<PAGE>
 
securities or property, or to receive any other right, the Company shall mail to
each holder of Preferred, at least 20 days prior to the date specified therein,
a notice specifying the date on which any such record is to be taken for the
purpose of such dividend, distribution, security or right, and the amount and
character of such dividend, distribution, security or right.

          (h)  Issue Taxes.  The Company shall pay any and all issue taxes and 
               -----------                                                     
other taxes that may be payable in respect of any issue or delivery of shares of
Common on conversion of shares of Preferred pursuant hereto; provided, however,
that the Company shall not be obligated to pay any transfer taxes resulting from
any transfer requested by any holder in connection with any such conversion.

          (i)  Notices.  Any notice required by the provisions of this 
               -------                                                     
Paragraph 4 to be given to the holders of shares of Preferred shall be deemed
given if deposited in the United States mail, postage prepaid, and addressed to
each holder of record at his address appearing on the books of the Company.

          (j)  The Company shall at all times keep a sufficient number of shares
of Common authorized to allow the conversion of Preferred as set forth in this
Section 4.

     5.   Voting Rights.
          ------------- 

          (a)  Except as otherwise required by law, by Section 5(b) or by
Section 6, the holder of each share of Common Stock issued and outstanding shall
have one vote and the holder of each share of the Series 1 Preferred shall be
entitled to the number of votes equal to the number of shares of Common Stock
into which such share of Series 1 Preferred could be converted at the record
date for determination of the shareholders entitled to vote on such matters, or,
if no such record date is established, at the date such vote is taken or any
written consent of shareholders is solicited, such votes to be counted together
with all other shares of stock of the Company having general voting power and
not separately as a class. Holders of Common Stock and Series 1 Preferred shall
be entitled to notice of any shareholders' meeting in accordance with the Bylaws
of the Company. Fractional votes by the holders of Series 1 Preferred shall not,
however, be permitted and any fractional voting rights shall (after aggregating
all shares into which shares of Series 1 Preferred held by each holder could be
converted) be rounded to the nearest whole number.

          (b)  Election/Removal of Directors.
               ----------------------------- 

               (i)  Series 1 Preferred Stock.  So long as at least 1,181,818 
                    ------------------------      
shares of Series 1 Preferred are outstanding (adjusted for any stock split,
consolidation or the like), the holders of the Series 1 Preferred shall be
entitled, voting as a separate class, to elect two (2) directors to the Board at
each annual meeting of shareholders, and (to the exclusion of the vote of
holders of the Common) to remove from office any or all of them and to fill any
vacancy or vacancies caused by the resignation, death or removal of any or all
of them.

               (ii) Common Stock.  So long as at least 1,818,818 shares of 
                    ------------   
Series 1 Preferred are outstanding (adjusted for any stock split, consolidation
or the like), the holders of Common Stock shall be entitled, voting as a
separate class, to elect two (2) directors to the Board at each annual meeting
of shareholders, and (to the exclusion of the vote of holders of Series 1
Preferred) to remove such directors from office and to fill any vacancy or
vacancies caused by the resignation, death or removal of such director or
directors.

               (iii) Voting As A Single Class.
                     ------------------------ 

                    (A)  So long as at least 1,818,818 shares of Series 1
Preferred are outstanding (adjusted for any stock split, consolidation or the
like, the holders of the Series 1 Preferred and Common Stock, voting together as
a single class (with the Series 1 Preferred voting as described in Section 5(a)
hereof) shall be entitled to elect the remaining directors to the Board at each
annual meeting of shareholders and to remove such directors from office and to
fill any vacancy or vacancies caused by the resignation, death or removal of
such director or directors.

                    (B) At such time as the number of shares of Series 1
Preferred outstanding shall fall below 1,818,818 (adjusted for any stock splits,
consolidations or the like), the holders of Common Stock and Series 1 Preferred
shall vote together as one class in the election and removal of directors, with
the Series 1 Preferred voting as described in Section 5(a) hereof.

     6.   Covenants.  In addition to any other rights provided by law, so long
          ---------                                                           
as at least 1,181,818 shares of the Series 1 Preferred (appropriately adjusted
for any stock split, consolidation or the like) shall be outstanding, the
Company shall not, without first obtaining the affirmative vote or written
consent of the holders of a majority of the outstanding shares of Series 1
Preferred:

          (a)  amend or repeal any provision of, or add any provision to, the

provided for the benefit of, the Series 1 Preferred;

          (b)  authorize any additional shares of Series 1 Preferred Stock;

          (c)  authorize or issue shares of any class of stock having any

having any preference or priority superior to or on a parity with the
preferences or priorities of the Series 1 Preferred; or

          (d)  declare or pay, or set aside for payment, any dividends on the
Common (other than dividends payable solely in shares of Common Stock);

                                      -11-

          (e)  effect any sale, transfer or other conveyance of all or
substantially all of the assets of the Company or any consolidation, merger or
other transaction pursuant to which the holders of the Company's capital stock
immediately prior to such transaction own less than a majority of the voting
capital stock of the surviving or continuing entity by virtue of their ownership
of Company capital stock;

          (f)  amend the Company's by-laws to increase the number of authorized
directors above five (5); or

          (g)  increase above 2,000,000 the number of shares of Common Stock

constitute a quorum.

2.7  ADJOURNED MEETING; NOTICE
     -------------------------

  Any shareholders' meeting, annual or special, whether or not a quorum is

that any election for directors must be by ballot if demanded by any shareholder
at the meeting and before voting  has begun.

  Except as provided in the last paragraph of this Section 2.8, or as may be
otherwise provided in the articles of incorporation, each outstanding share,
regardless of class, shall be entitled to one vote on each matter submitted to a
vote of the shareholders. Any shareholder entitled to vote on any matter may
vote part of the shares in favor of the proposal and refrain from voting the
remaining shares or, except when the matter is the election of directors, may
vote them against the proposal; but, if the shareholder fails

<PAGE>
 
to specify the number of shares which the shareholder is voting affirmatively,
it will be conclusively presumed that the shareholder's approving vote is with
respect to all shares which the shareholder is entitled to vote.

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

  At a shareholders' meeting at which directors are to be elected, a shareholder
shall be entitled to cumulate votes (i.e., cast for any candidate a number of
votes greater than the number of votes which such shareholder normally is
entitled to cast) if the candidates' names have been placed in nomination prior
to commencement of the voting and the shareholder has given notice prior to
commencement of the voting of the shareholder's intention to cumulate votes.
If any shareholder has given such a notice, then every shareholder entitled to
vote may cumulate votes for candidates in nomination either (i) by giving one
candidate a number of votes -equal to the number of directors to be elected
multiplied by the number of votes to which that shareholder's shares are
normally entitled or (ii) by distributing the shareholder's votes on the same
principle among any or all of the candidates, as the shareholder thinks fit.

number of directors to be elected, shall be elected; votes against any candidate
and votes withheld shall have no legal effect.

person entitled to vote, who was not present in person or by proxy, signs a
written waiver of notice or a consent to the holding of the meeting or an
approval of the minutes thereof. The waiver of notice or consent or approval
need not specify either the business to be transacted or the purpose of any
annual or special meeting of shareholders, except that if action is taken or
proposed to be taken for approval of any of those matters specified in the
second paragraph of Section 2.4 of these bylaws, the waiver of notice or consent
or approval shall state the general nature of the proposal. All such waivers,
consents, and approvals shall be filed with the corporate records or made a part
of the minutes of the meeting.

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

outstanding shares having not less than the minimum number of votes that would
be necessary to authorize or take that action at a meeting at which all shares
entitled to vote on that action were present and voted.

shareholder giving a written consent, or the shareholder's proxy holders, or a
transferee of the shares, or a personal representative of the shareholder, or
their respective proxy holders, may revoke the consent by a writing receive  by
the secretary of the corporation before written consents of the number of shares
required to authorize the proposed action have been filed with the secretary.

  If the consents of all shareholders entitled to vote have not been solicited
in writing and if the unanimous written consent of all such shareholders has not
been received, then the secretary shall give prompt notice of the corporate
action approved by the shareholders without a meeting.  Such notice shall be
given to those shareholders entitled to vote who have not consented in writing
and shall be given in the manner specified in Section 2.5 of these bylaws.  In
the case of approval of (i) a contract or transaction in which a director has a
direct or indirect financial interest, pursuant to Section 310 of the Code, (ii)
indemnification of a corporate "agent," pursuant to Section 317 of the Code,

corporate action in writing without a meeting, (i) when no prior action by the

given, or (ii) when prior action by the board has been taken, shall be at the
close of business on the day on which the board adopts the resolution relating
to that action, or the sixtieth (60th) day before the date of such other action,

corporation stating that the proxy is revoked or by executing a subsequent proxy
and presenting it to the meeting or by voting in person at the meeting, or (ii)
written notice of the death or incapacity of the maker of that proxy is received
by the corporation before the vote pursuant to that proxy is counted; provided,
however, that no proxy shall be valid after the expiration of eleven (ii) months
from the date of the proxy, unless otherwise provided in the proxy. The dates
contained on the forms of proxy presumptively determine the order of execution,
regardless of the postmark dates on the envelopes in which they are mailed. The

governed by the provisions of Sections 705(e) and 705(f) of the Code.

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

8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING
     -----------------------------------------------------

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

                                     -21-

the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

8.3  CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED
     --------------------------------------------------

  The board of directors, except as otherwise provided in these bylaws, may
authorize any officer or officers, or agent or agents, to enter into any

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

8.4  CERTIFICATES FOR SHARES
     -----------------------

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

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

be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time.  The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

8.6  CONSTRUCTION; DEFINITIONS
     -------------------------

  Unless the context requires otherwise, the general provisions, rules of

bylaws.  Without limiting the generality of this provision, the singular number
includes the plural, the plural number includes the singular, and the term
"person"includes both a corporation and a natural person.

                       INTERLINK COMPUTER SCIENCES, INC.

       AMENDMENT TO REGISTRATION RIGHTS AGREEMENT DATED JANUARY 27,1994



     This Amendment is made effective as of April 25, 1996 and amends the
Registration Rights Agreement dated January 27, 1994, as amended on December 27,
1995, (the "Agreement") by and among the Company and the holders of Restricted
Securities (as defined in the AGREEMENT).

1.   Section 5.4 of the Agreement is hereby amended in its entirety to read as
follows:

     "Allocation of Shares in Registrations.
      ------------------------------------- 
     (a) For the purposes of this Section 5.4, "Initial Public Offering" is
defined as the first public registration of the Company's Common Stock on Form
S-1, or similar form, filed and made effective by the Securities and Exchange
Commission under the Securities Act of 1933, as amended (the "Act"). Exclusively
for the purposes of the Initial Public Offering, the Holders will allow the
Company, in consultation with the underwriters, to include as Registrable
Securities those shares held by holders of securities who are not currently
officers or directors of the Company and who are not subject to a lock-up period
substantially similar to Section 5.7 of the Agreement (the "Additional
Holders"). For the purposes of this Section 5.4, the securities held by the
Additional Holders will be included in the definition of Registrable Securities.

     (b) Notwithstanding any other provision of this Agreement, if the managing
underwriter advises the Company and/or the Initiating Holders in writing that
marketing factors require a limitation of the number of shares to be
underwritten, then the underwriter may exclude some or all Registrable
Securities from such registration and underwriting as to the Initial Public
Offering, and as to subsequent registrations, the underwriters may exclude
Registrable Securities proposed to be registered, but only so long as the
Registrable Securities comprise at least 30% of the offering. In the event that
the number of shares of Registrable Securities to be included in a registration
shall be limited pursuant to the foregoing, the Company shall so advise all
Holders and Additional Holders, and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated among all Holders and Additional Holders in proportion, as nearly as
practicable, to the respective amounts of Restricted Securities then held by
Holders and Additional Holders requesting to have shares included in the
registration statement. No Registrable Securities excluded from the underwriting
by reason of the underwriter's marketing limitation shall be included in such
registration.

     (c) Notwithstanding any other provision of this Section 5.4, to facilitate
the allocation of shares in accordance with the above provisions, the Company
and/or the underwriters may allow each Holder and Additional Holder to include
in the Initial Public Offering up to the greater of (i) 1,000 shares or (ii) the
proportionate amount calculated in Section 5.4(b) above. Any Holders or
Additional Holders who hold fewer than 1,000 Common or Preferred Shares will be
required to sell their entire holding if they wish to participate in the Initial
Public Offering."

     2.   Miscellaneous. This Amendment will be effective upon execution by a
          -------------                                                      
majority in interest of the Holders of Restricted Securities (as defined in the
Agreement). The other provisions of the Agreement shall continue in full force
and effect pursuant to its terms. This Amendment shall constitute the consent of
the undersigned under Section 5.11 and Section 7 of the Agreement to the extent
that this Amendment provides additional registration rights or adversely affects
the Holders' existing registration rights. This Amendment shall be governed by
the laws of the state of California, without regard to their conflicts of laws
provisions. This Amendment may be executed in one or more counterparts, each of
which shall be deemed an original, and all of which together shall constitute
one instrument,

     The foregoing AMENDMENT TO REGISTRATION RIGHTS AGREEMENT is hereby executed
as of the date first above written.

     3.   Restrictive  Legend.  Each  certificate  representing Restricted

Securities  shall  (unless  otherwise  permitted by  the provisions of Section 4

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
          INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF

          SUCH REGISTRATION OR UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL
          REASONABLY ACCEPTABLE TO IT STATING THAT SUCH SALE OR TRANSFER IS
          EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF
          SAID ACT.

     4.   Notice of Proposed Transfers.  The holder of each certificate
          ----------------------------                                 
representing Restricted Securities, by acceptance thereof, agrees to comply in
all respects with the provisions of this Section 4. Prior to any proposed
transfer of any Restricted Securities, unless there is in effect a registration
statement under the Securities Act covering the proposed transfer, the holder
thereof shall give written notice to the Company of such holder's intention
to effect such transfer.  Each such notice shall describe the manner and
circumstances of the proposed transfer in sufficient detail and shall, if the
Company so requests, be accompanied by either (i) a written opinion of legal
counsel who shall be reasonably satisfactory to the Company addressed to the
Company and reasonably satisfactory in form and substance to the Company's
counsel to the effect that the proposed transfer of the Restricted Securities
may be effected without registration under the Securities Act or (ii) a "no
action" letter from the Commission to the effect that the transfer of such
securities without registration will not result in a recommendation by the staff
of the Commission that action be taken with respect thereto, whereupon the

                                      -3-
<PAGE>
 
holder of such Restricted Securities shall be entitled to transfer such
Restricted Securities in accordance with the terms of the notice delivered by
the holder to the Company; provided, however, that no opinion or no action
letter need be obtained with respect to a transfer without consideration to 
(A) any affiliated entity of a holder of Restricted Securities, (B) a partner
active or retired, of a holder of Restricted Securities, (C) the estate of any
such partner or a trust established for the benefit of the descendants or any
relatives or spouse of such partner, (D) to a parent corporation or wholly-owned
subsidiary of a holder of Restricted Securities or to a wholly-owned subsidiary
of such parent, or (E) to the spouse of a holder of Restricted Securities;
provided, in any such case, that the transferee agrees in writing to be subject
to the terms hereof. Each certificate evidencing the Restricted Securities
transferred as above provided shall bear the appropriate restrictive legend set
forth in Section 3 above, except that such certificate shall not bear such
restrictive legend if in the opinion of counsel for the Company such legend is
not required in order to establish compliance with any provisions of the
Securities Act.

     5.   Registration Rights.
          ------------------- 

          5.1  Requested Registration.
               ---------------------- 

               (a)  In case the Company shall receive from Initiating Holders a
written request that the Company effect any registration, qualification or
compliance with respect to some or all of the Registrable Securities held by
them and, provided such registration will involve the sale of Common Stock to
the public at an offering price of at least $6.875 per share (subject to
appropriate adjustment for stock splits, dividends, combinations and the like)
and an aggregate offering price to the public of at least $10,000,000, the
Company will:

                    (i)   promptly give written notice of the proposed
registration, qualification or compliance to all other Holders; and

                    (ii)  as soon as practicable, use its best lawful efforts to
effect such registration, qualification or compliance (including, without
limitation, appropriate qualification under applicable blue sky or other state
securities law and appropriate compliance with applicable regulations issued
under the Securities Act and any other governmental requirements or regulations)
as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities or Commonholders' Registrable Securities of any Holders joining in
such request as are specified in a written request received

                                      -4-
<PAGE>
 
by the Company within 15 days after receipt of such written notice from the
Company; provided, however, that the Company shall not be obligated to take
any action to effect any such registration, qualification or compliance
pursuant to this Section 5.1:

                    (A)   In any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                    (B)   Prior to six months following the Company's first
registration under the Securities Act;

                    (C)   During the period starting with the date sixty (60)
days prior to the Company's estimated date of filing of, and ending on the date
three (3) months immediately following the effective date of, any registration
statement pertaining to securities of the Company (other than a registration 
of securities in a Rule 145 transaction or with respect to an employee benefit 
plan), providing that the Company is actively employing in good faith all
reasonable efforts to cause such registration statement to become effective 
(and provided, further, that the Company cannot pursuant to this Section 5.1
(a)(ii)(C) delay implementation of a demand for registration more than once in
any 24-month period);

                    (D)   After the Company has effected two such registrations
pursuant to this subsection 5.1, and such registrations have been declared or
ordered effective; or

                    (E)   If the Company shall furnish to such Holders a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company or its shareholders for a registration statement to be filed in the
near future, then the Company's obligation to use its best lawful efforts to
register, qualify or comply under this Section 5.1 shall be deferred once (with
respect to any demand for registration hereunder) for a period not to exceed
ninety (90) days from the date of receipt of written request from the Initiating
Holders, provided that the Company may, by furnishing another certificate
pursuant to this Section 5.1(a)(ii)(E), delay implementation of a demand for
registration for successive periods of up to ninety (90) days each.

               Subject to the foregoing clauses (A) through (E), the Company
shall file a registration statement covering the Registrable Securities so
requested to be registered as soon as practicable after receipt of the request
or requests of the Initiating Holders.

                                      -5-
<PAGE>
 
               (b)  Underwriting. In the event that a registration pursuant to
                    ------------
 Section 5.1 is for a registered public offering involving an underwriting, the
 Company shall so advise the Holders as part of the notice given pursuant to
 Section 5.1(a)(i).  In such event, the right of any Holder to registration
 pursuant to Section 5.1 shall be conditioned upon such Holder's participation
 in the underwriting arrangements required by this Section 5.1, and the
 inclusion of such Holder's Registrable Securities in the underwriting to the
 extent requested shall be limited to the extent provided in Section 5.4 hereof.

               The Company, together with all Holders and other holders
proposing to distribute their securities through such underwriting, shall enter
into an underwriting agreement in customary form with the managing underwriter
selected for such underwriting by a majority in interest of the Initiating
Holders, but subject to the Company's reasonable approval. If any Holder of
Registrable Securities (or other holder distributing its securities through the
underwriting) disapproves of the terms of the underwriting, such person may
elect to withdraw therefrom by written notice to the Company, the managing
underwriter and the Initiating Holders. The Registrable Securities and/or other
securities so withdrawn shall also be withdrawn from registration, and such
Registrable Securities shall not be transferred in a public distribution prior
to 180 days after the effective date of such registration, or such other shorter
period of time as the underwriters may require.

               (c)  The Company shall not register securities for sale for its
own account in any registration requested pursuant to this Section 5.1 unless
permitted to do so by the written consent of Holders who hold a majority of the
Registrable Securities as to which registration has been requested or unless the
underwriter shall indicate in writing to the Initiating Holders that the
inclusion of the shares to be sold for the account of the Company will not
adversely affect the registration, the price of the shares to be sold and the
number of shares to be sold for the account of the Holders. The Company may not
cause any other registration of securities for sale for its own account (other
than a registration effected solely to implement an employee benefit plan or
stock option plan or a transaction contemplated by Rule 145 of the Commission)
to be initiated after a registration requested pursuant to Section 5.1 and to
become effective less than 9O days after the effective date of any registration
requested pursuant to Section 5.1.

          5.2  Piggy-Back Registration.  If at any time the Company shall
               -----------------------
determine to register any of its securities other than (i) a registration
relating solely to employee benefit plans, (ii) a registration relating solely
to a Commission Rule 145 transaction or

                                      -6-
<PAGE>
 
(iii) a registration in which the only Common Stock being registered is Common
Stock issuable upon conversion of convertible debt securities that are also
being registered, then:

               (a)  the Company will promptly give to each Holder written notice
thereof; and

               (b)  will, subject to Section 5.4, include in such registration
(and any related qualification under state securities laws) and in any
underwriting involved therein all the Registrable Securities specified in a
written request or requests made within 15 days after receipt of such written
notice from the Company by any Holder.

          5.3  Registration on Form S-3.   If a Holder or Holders request that
               ------------------------
the Company file a registration statement on Form S-3 (or any successor thereto)
for a public offering of shares of the Registrable Securities, the reasonably
anticipated aggregate price to the public of which would exceed $1,000,000, and
the Company is a registrant entitled to use Form S-3 to register such shares for
such an offering, the Company shall use its best efforts to cause such shares to
be registered for the offering on such form (or any successor thereto) . In the
event of a request pursuant to this Section 5.3, the Company shall follow the
procedures, and the rights and obligations of the parties shall be subject to
the limitations, set forth in Section 5.1 as if such Section applied to
registrations on Form S-3; disregarding, however, the transaction size
requirements of Section 5.1(a).

          5.4  Allocation of Shares in Registrations.  Notwithstanding any other
               -------------------------------------                            
provision of this Agreement, if the managing underwriter advises the Company
and/or the Initiating Holders in writing that marketing factors require a
limitation of the number of shares to be underwritten, then the underwriter may
exclude some or all Registrable Securities from such registration and
underwriting as to the first registered public offering of the Company's Common
Stock, and as to subsequent registrations, the underwriters may exclude
Registrable Securities proposed to be registered, but only so long as the
Registrable Securities comprise at least 30% of the offering.  In the event that
the number of shares of Registrable Securities to be included in a registration
shall be limited pursuant to the foregoing, the Company shall so advise all
Holders, and the number of shares of Registrable Securities that may be included
in the registration and underwriting shall be allocated among all Holders in
proportion,  as nearly as practicable, to the respective amounts of Restricted
Securities then held by Holders requesting to have shares included in the
registration statement.  No Registrable Securities excluded from the
underwriting by reason of the underwriter's marketing limitation shall be
included

                                      -7-
<PAGE>
 
in such registration.   To facilitate the allocation of shares in accordance
with the above provisions, the Company or the underwriters may round the number
of shares allocated to any Holder to the nearest 100 shares.


          5.5  Expenses of Registration.
               ------------------------ 

               (a)  All Registration Expenses incurred in connection with any
registration, qualification or compliance pursuant to Section 5.1 or 5.2
shall be borne by the Company.  Unless otherwise stated, all Selling Expenses
relating to securities registered by the Holders shall be borne by the holders
of such securities pro rata on the basis of the number of shares so registered.

               (b)  With respect to the first two registrations effected
pursuant to Section 5.3, all Registration Expenses incurred shall be borne by
the Company and all Selling Expenses relating to securities registered by the
Holders in such registrations shall be borne by the holders of such securities
pro rata on the basis of the number of shares so registered. With respect to any
additional registrations effected pursuant to Section 5.3, all Registration and
Selling Expenses shall be borne by the Holder or Holders participating in the
registration on Form S-3 pro rata according to the number of Registrable
Securities so registered.

          5.6  Registration Procedures.
               ----------------------- 

               (a)  In the case of each registration, qualification or
compliance effected by the Company pursuant to this Agreement, the Company will
keep each Holder advised in writing as to the initiation of each registration,
qualification and compliance and as to the completion thereof. At its expense
the Company will:

                    (i)   Keep such registration, qualification or compliance
effective for a period of 120 days or until the Holder or Holders have completed
the distribution described in the registration statement relating thereto,
whichever first occurs;

                    (ii)  Furnish such number of prospectuses and other
documents incident thereto as a Holder from time to time may reasonably request;

                    (iii) Prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Securities Act with

                                      -8-
<PAGE>
 
respect to the disposition of all securities covered by such registration
statement; and

                    (iv)  In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

               (b)  In the event of any registration pursuant to Sections 5.1 or
5.2 hereof, the Company will exercise its best efforts to register and qualify
the securities covered by the registration statement under such other securities
laws of such jurisdictions (not exceeding 20 unless otherwise agreed to by the
Company) as shall be reasonably appropriate for the distribution of such
securities; provided, however, that (i) the Company shall not be required to
qualify to do business or to file a general consent to service of process in any
such states or jurisdictions, and (ii) notwithstanding anything in this Section
8(b) to the contrary, in the event any jurisdiction in which the securities
shall be qualified imposes a non-waivable requirement that expenses incurred in
connection with the qualification of the securities be borne by selling Holders,
such expenses shall be payable pro rata by selling Holders.

               (c)  Information by Holder.  The holder or holders of Registrable
                    ---------------------
Securities included in any registration shall furnish to the Company such
information regarding such party and the distribution proposed by such holder or
holders as the Company may request in writing and as shall be required in
connection with any registration, qualification or compliance referred to in
this Agreement.

         5.7   Lockup Agreement.  In consideration for the Company agreeing to
               ----------------
its obligations under this Agreement, each Holder hereby agrees in connection
with the first registration of the Company's securities not to sell, make any
short sale of, loan, grant any option for the purchase of, or otherwise dispose
of any Registrable Securities (other than those included in the registration)
without the prior written consent of the Company or underwriters managing the
offering, as the case may be, for such period of time from the effective date of
such registration as the underwriters may specify; provided, however, that such
Holder shall be relieved of its obligations under this Section 5.7 unless all
executive officers and directors of the Company enter into similar agreements.
Each Holder hereby agrees that, upon the request of the Company or the
underwriters, it will confirm in writing the provisions of this Section 5.7.

                                      -9-

          5.8  Indemnification
               ---------------

               (a)  The Company will indemnify each Holder, each of its officers
and directors and partners and such Holder's legal counsel and independent
accountants, and each person controlling such Holder within the meaning of
Section 15 of the Securities Act, with respect to which registration,
qualification or compliance has been effected pursuant to this Agreement, and
each underwriter, if any, and each person who controls any underwriter within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof) , including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any registration statement,
prospectus, offering circular or other document, or any amendment or supplement
thereto, incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by the Company of any rule or regulation
promulgated under the Securities Act applicable to the Company and relating to
action or inaction required of the Company in connection with any such
registration, qualification or compliance, and will reimburse each such Holder,
each of its officers and directors and such Holder's legal counsel and
independent accountants, and each person controlling such Holder, each such
underwriter and each person who controls any such underwriter, for any legal and
any other expenses reasonably incurred in connection with investigating,
preparing or defending any such claim, loss, damage, liability or action,
provided that the Company will not be liable in any such case to the extent that
any such claim, loss, damage, liability or expense arises out of or is based on
any untrue statement or omission or alleged untrue statement or omission in a
registration statement or prospectus, made in reliance upon and in conformity
with written information furnished to the Company by a Holder or underwriter
specifically for use therein; provided, however, that the foregoing indemnity
agreement is subject to the condition that, insofar as it relates to any such
untrue statement, alleged untrue statement, omission or alleged omission made in
a preliminary prospectus on file with the Commission at the time the
registration statement becomes effective or the amended prospectus filed with
the Commission pursuant to Rule 424(b) (the "Final Prospectus"), such indemnity
agreement shall not inure to the benefit of any underwriter or any Holder, if
there is no underwriter, if the untrue statement (or alleged untrue statement)
or omission (or alleged omission) was corrected in the Final Prospectus and a
copy of the Final Prospectus was not furnished to the person asserting the loss,
liability, claim or damage at or prior to the time such action is required by
the Securities Act.

                                     -10-
<PAGE>
 
               (b)  Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers and its legal counsel and independent accountants,
each underwriter, if any, of the Company's securities covered by such a
registration statement, each person who controls the Company or such underwriter
within the meaning of Section 15 of the Securities Act, and each other such
Holder, each of its officers and directors and each person controlling such
Holder within the meaning of Section 15 of the Securities Act, against all
claims, losses, damages and liabilities (or actions in respect thereof) arising
out of or based on any untrue statement (or alleged untrue statement) of a
material fact contained in any such registration statement, prospectus, offering
circular or other document, or any omission (or alleged omission) to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse the Company, such Holders,
such directors, officers, legal counsel, independent accountants, underwriters
or control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by such Holder specifically for use therein; provided,
however, that the obligations of such Holders hereunder shall be limited to an
amount equal to the proceeds to each such Holder of Registrable Securities sold
as contemplated herein and provided further that the foregoing indemnity
agreement is subject to the condition that, insofar as it relates to any such
untrue statement, alleged untrue statement, omission or alleged omission made in
a preliminary prospectus on file with the Commission at the time the
registration statement becomes effective or the Final Prospectus, such indemnity
agreement shall not inure to the benefit of the Company, any underwriter or any
Holder, if there is no underwriter, if the untrue statement) or omission (or
alleged omission) was corrected in the Final Prospectus and a copy of the Final
Prospectus was not furnished to the person asserting the loss, liability, claim
or damage at or prior to the time such action is required by the Securities Act.

               (c)  Each party entitled to indemnification under this Section
5.8 (the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the

                                     -11-
<PAGE>
 
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement.   No Indemnifying
Party, in the defense of any such claim or litigation, shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect to such claim or litigation.

          5.9  Rule 144 Reporting.  With a view to making available the benefits
               ------------------
of certain rules and regulations of the Commission that may at any time permit
the sale of the Restricted Securities to the public without registration, after
such time as a public market exists for the Common Stock of the Company, the
Company agrees to:

               (a)  Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date of the first registration under the Securities Act
filed by the Company for an offering of its securities to the general public;

               (b)  Use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the

accordance with Section 2(j) of the Plan;

               (ii) to select the officers, Consultants and Employees to whom
Options and Rights may from time to time be granted hereunder;

<PAGE>
 
               (iii) to determine whether and to what extent Options and Rights
are granted hereunder; 

               (iv) to determine the number of shares of Stock to be covered by
each award granted hereunder;

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

               (vi) to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any award granted hereunder (including, but not
limited to, the share price and any restriction or limitation, or waiver of
forfeiture restrictions regarding any Option or Right and/or the shares of Stock
relating thereto, based in each case on such factors as the Administrator shall
determine, in its sole discretion);

               (vii) to reduce the exercise price of any Option or Right;

               (viii) to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws.

               (ix) to make all other determinations deemed necessary or
advisable for administering the Plan.

          (c) Effect of Committee's Decision.  All decisions, determinations and
              ------------------------------                                    
interpretations of the Administrator shall be final and binding on all Optionees
and any other holders of Options or Rights.

     5.   Eligibility.  Nonstatutory Stock Options, Stock Purchase Rights, and
          -----------                                                         
Long-Term Performance Awards may be granted to Employees and Consultants.
Incentive Stock Options may be granted only to Employees.  An Employee or
Consultant who has been granted an Option or Right may, if he or she is
otherwise eligible, be granted an additional Options or Rights.

     6.   Limitations.
          ----------- 

          (a)  Each Option shall be designated in the written option agreement 
as either an Incentive Stock Option or a Nonstatutory Stock Option.  However,
notwithstanding such designations, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Options designated as Incentive Stock
Options are exercisable for the first time by any Optionee during any calendar
year (under all plans of the Company or any Parent or Subsidiary) exceeds
$100,000, such excess Options shall be treated as Nonstatutory Stock Options.

          (b)  For purposes of Section 6(a), Incentive Stock Options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the Shares shall be determined as of the time the Option with respect
to such Shares is granted.

                                      -5-
<PAGE>
 
          (c)  Neither the Plan nor any Option or Right shall confer upon any
Optionee any right with respect to continuation of employment or consulting
relationship with the Company, nor shall it interfere in any way with his or her
right or the Company's right to terminate his or her employment or consulting
relationship at any time, with or without cause.
 
          (d)  The following limitations shall apply to grants of Options to
Employees:

               (i)  No Employee shall be granted, in any fiscal year of the
Company, Options to purchase more than 500,000 Shares.

               (ii) In connection with his or her initial employment, an
Employee may be granted Options to purchase up to an additional 500,000 Shares
which shall not count against the limit set forth in subsection (i) above.

               (iii) The foregoing limitations shall be adjusted proportionately
in connection with any change in the Company's capitalization as described in
Section 15.

               (iv) If an Option is cancelled in the same fiscal year of the
Company in which it was granted (other than in connection with a transaction
described in Section 15), the cancelled Option will be counted against the
limits set forth in subsections (i) and (ii) above.  For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.
 
     7.   Term of Plan.  The Plan shall become effective upon the earlier to
          ------------                                                      
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company as described in Section 21 of the Plan.  It shall
continue in effect until June 1, 2002 unless sooner terminated under Section 17
of the Plan.

     8.   Term of Option.  The term of each Option shall be the term stated in
          --------------                                                      
the Option Agreement.  In the case of an Incentive Stock Option, the term shall
be no more than ten (10) years from the date of grant thereof or such shorter
term as may be provided in the Option Agreement.  In the case of an Option
granted to an Optionee who, at the time the Option is granted, owns stock
representing more than ten percent (10%) of the voting power of all classes of
stock of the Company or any Parent or Subsidiary, the term of the Option shall
be five (5) years from the date of grant thereof or such shorter term as may be
provided in the Option Agreement.

     9.   Option Exercise Price and Consideration.
          --------------------------------------- 

          (a)  The per share exercise price for the Shares to be issued pursuant
to exercise of an Option shall be such price as is determined by the Board, but
shall be subject to the following:

               (i)  In the case of an Incentive Stock Option

                    (A) granted to an Employee who, at the time of the grant of
such Incentive Stock Option, owns stock representing more than ten percent (10%)
of the voting power 

                                      -6-
<PAGE>
 
of all classes of stock of the Company or any Parent or Subsidiary, the per
Share exercise price shall be no less than 110% of the Fair Market Value per
Share on the date of grant.

                    (B) granted to any other Employee, the per Share exercise
price shall be no less than 100% of the Fair Market Value per Share on the date
of grant.

               (ii) In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Administrator on the date of grant.

          (b)  The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) promissory note, (4) other shares of the Company's capital stock
which (x) in the case of shares of the Company's capital stock acquired upon
exercise of an Option either have been owned by the Optionee for more than six
months on the date of surrender or were not acquired, directly or indirectly,
from the Company, and (y) have a Fair Market Value on the date of surrender
equal to the aggregate exercise price of the Shares as to which said Option
shall be exercised, (5) delivery of a properly executed exercise notice together
with irrevocable instructions to a broker to promptly deliver to the Company the
amount of sale or loan proceeds required to pay the exercise price, (6) a
reduction in the amount of any Company liability to the Optionee, including any
liability attributable to the Optionee's participation in any Company-sponsored
deferred compensation program or arrangement; or (7) any combination of the
foregoing methods of payment.

     10.  Exercise of Option.
          ------------------ 

          (a)  Procedure for Exercise; Rights as a Shareholder. Any Option 
               -----------------------------------------------
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Board, including perfor mance criteria with respect to the
Company and/or the Optionee, and as shall be permissible under the terms of the
Plan. An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised, and the Optionee
deemed to be a shareholder of the shares being purchased upon exercise, when
written notice of such exercise has been given to the Company in accordance with
the terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Board, consist
of any consideration and method of payment allowable under Section 9(b) of the
Plan.

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

          (b)  Termination of Employment or Consulting Relationship.  Upon
               ----------------------------------------------------       
termination of an Optionee's Continuous Status as an Employee or Consultant,
other than upon the Optionee's death or Disability, the Optionee may exercise
his or her Option within such period of time as is specified in the Option
Agreement to the extent that he or she is entitled to exercise it on the date of

                                      -7-
<PAGE>
 
termination (but in no event later than the expiration of the term of such
Option as set forth in the Option Agreement). In the absence of a specified time
in the Option Agreement, the Option shall remain exercisable for three (3)
months following the Optionee's termination. In the case of an Incentive Stock
Option, such period of time for exercise shall not exceed three (3) months from
the date of termination. If, on the date of termination, the Optionee is not
entitled to exercise his or her entire Option, the Shares covered by the
unexercisable portion of the Option shall revert to the Plan. If, after
termination, the Optionee does not exercise his or her Option within the time
specified by the Administrator, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

          Notwithstanding the above, in the event of an Optionee's change in
status from Consultant to Employee or Employee to Consultant, the Optionee's
Continuous Status as an Employee or Consultant shall not automatically terminate
solely as a result of such change in status.  In such event, an Incentive Stock
Option held by the Optionee shall cease to be treated as an Incentive Stock
Option and shall be treated for tax purposes as a Nonstatutory Stock Option
three months and one day following such change of status.

          (c)  Disability of Optionee.  Upon termination of an Optionee's
               ----------------------                                    
Continuous Status as an Employee or Consultant as a result of the Optionee's
total and permanent disability (as defined in Section 22(c)(3) of the Code, the
Optionee may exercise his or her Option at any time within twelve (12) months
from the date of termination, but only to the extent that the Optionee is
entitled to exercise it on the date of termination (and in no event later than
the expiration of the term of the Option as set forth in the Option Agreement).
If, on the date of termination, the Optionee is not entitled to exercise his or
her entire Option, the Shares covered by the unexercisable portion of the Option
shall revert to the Plan. If, after termination, the Optionee does not exercise
his or her Option within the time specified herein, the Option shall terminate,
and the Shares covered by such Option shall revert to the Plan.

          (d)  Death of Optionee.  Upon the death of an Optionee, the Option 
               -----------------
may be exercised at any time within twelve (12) months following the date of
death (but in no event later than the expiration of the term of such Option as
set forth in the Option Agreement), by the Optionee's estate or by a person who
acquires the right to exercise the Option by bequest or inheritance, but only to
the extent that the Optionee would have been entitled to exercise the Option on
the date of death. If, at the time of death, the Optionee is not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan. If the Optionee's
estate or the person who acquires the right to exercise the Option by bequest or
inheritance does not exercise the Option within the time specified herein, the
Option shall terminate, and the Shares covered by such Option shall revert to
the Plan.

          (e)  Rule 16b-3.  Options granted to persons subject to Section 16(b) 
               ----------
of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

     11.  Stock Purchase Rights.
          --------------------- 

                                      -8-
<PAGE>
 
          (a)  Rights to Purchase.  Stock Purchase Rights may be issued either
               ------------------                                             
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing, by means of a Notice of Grant, of the terms, conditions and
restrictions related to the offer, including the number of Shares that the
offeree shall be entitled to purchase, the price to be paid, and the time within
which the offeree must accept such offer, which shall in no event exceed six (6)
months from the date upon which the Administrator made the determination to
grant the Stock Purchase Right. The offer shall be accepted by execution of a
Restricted Stock Purchase Agreement in the form determined by the Administrator.

          (b)  Repurchase Option.  Unless the Administrator determines 
               ----------------- 
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's employment with the Company for any reason (including death or
Disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at a rate determined by the
Administrator.

          (c)  Rule 16b-3.  Stock Purchase Rights granted to Insiders, and 
               ----------      
Shares purchased by Insiders in connection with Stock Purchase Rights, shall be
subject to any restrictions applicable thereto in compliance with Rule 16b-3. An
Insider may only purchase Shares pursuant to the grant of a Stock Purchase
Right, and may only sell Shares purchased pursuant to the grant of a Stock
Purchase Right, during such time or times as are permitted by Rule 16b-3.

          (d)  Other Provisions.  The Restricted Stock Purchase Agreement shall
               ----------------                                                
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Admin istrator in its sole discretion.  In
addition, the provisions of Restricted Stock Purchase Agreements need not be the
same with respect to each purchaser.

          (e)  Rights as a Shareholder.  Once the Stock Purchase Right is
               -----------------------                                   
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company.  No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 15
of the Plan.

     12.  Long-Term Performance Awards.
          ---------------------------- 

          (a)  Administration.  Long-Term Performance Awards are cash or stock
               --------------                                                 
bonus awards that may be granted either alone or in addition to other awards
granted under the Plan.  Such awards may be granted for no cash consideration.
The Administrator shall determine the nature, length and starting date of any
performance period (the "Performance Period") for each Long-Term Performance
Award, and shall determine the performance or employment factors, if any, to be
used in the determination of Long-Term Performance Awards and the extent to
which such Long-Term Performance Awards are valued or have been earned.  Long-
Term Performance Awards may vary from participant to participant and between
groups of participants and shall be based upon the achievement of Company,
Subsidiary, Parent and/or individual performance factors or upon such 

                                      -9-
<PAGE>
 
other criteria as the Administrator may deem appropriate. Performance Periods
may overlap and participants may participate simultaneously with respect to 
Long-Term Performance Awards that are subject to different Performance Periods
and different performance factors and criteria. Long-Term Performance Awards
shall be confirmed by, and be subject to the terms of, Long-Term Performance
Award agreements. The terms of such awards need not be the same with respect to
each participant.

          At the beginning of each Performance Period, the Administrator may
determine for each Long-Term Performance Award subject to such Performance
Period the range of dollar values or number of shares of Common Stock to be
awarded to the participant at the end of the Performance Period if and to the
extent that the relevant measures of performance for such Long-Term Performance
Award are met. Such dollar values or number of shares of Common Stock may be
fixed or may vary in accordance with such performance or other criteria as may
be determined by the Administrator.

          (b)  Adjustment of Awards.  The Administrator may adjust the 
               --------------------
performance factors applicable to the Long-Term Performance Awards take into
account changes in legal, accounting and tax rules and to make such adjustments
as the Administrator deems necessary or appropriate to reflect the inclusion or
exclusion of the impact of extraordinary or unusual items, events or
circumstances in order to avoid windfalls or hardships.

     13.  Stock Withholding to Satisfy Withholding Tax Obligations.  At the
          --------------------------------------------------------         
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph.  When an Optionee incurs tax liability in
connection with an Option, which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by electing to have the Company withhold
from the Shares to be issued upon exercise of the Option, that number of Shares
having a Fair Market Value equal to the amount required to be withheld.  The
Fair Market Value of the Shares to be withheld shall be determined on the date
that the amount of tax to be withheld is to be determined (the "Tax Date").

          All elections by an Optionee to have Shares withheld for this purpose
shall be made in writing in a form acceptable to the Administrator and shall be
subject to the following restrictions:

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

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

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

          (d)  if the Optionee is subject to Rule 16b-3, the election must
comply with the applicable provisions of Rule 16b-3 and shall be subject to such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

                                      -10-
<PAGE>
 
          In the event the election to have Shares withheld is made by an
Optionee and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Optionee shall receive
the full number of Shares with respect to which the Option is exercised but such
Optionee shall be unconditionally obligated to tender back to the Company the
proper number of Shares on the Tax Date.

     14.  Non-Transferability of Options and Rights.  Options and Rights may not
          -----------------------------------------                             
be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or by the laws of descent or distribution and may be
exercised, during the lifetime of the Optionee, only by the Optionee.

     15.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
          ------------------------------------------------------------------
Asset Sale.
- ---------- 

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

          (b)  Dissolution or Liquidation.  In the event of the proposed
               --------------------------                               
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

          (c)  Merger or Asset Sale.  In the event of a merger of the Company
               --------------------                                          
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option and Right shall be assumed or an
equivalent option or right substituted by the successor corporation or a Parent
or Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the Option or Right, the
Optionee shall have the right 

                                      -11-
<PAGE>
 
to exercise the Option or Right as to all of the Optioned Stock, including
Shares as to which it would not otherwise be exercisable. If an Option or Right
is exercisable in lieu of assumption or substitution in the event of a merger or
sale of assets, the Administrator shall notify the Optionee that the Option or
Right shall be fully exercisable for a period of fifteen (15) days from the date
of such notice, and the Option or Right shall terminate upon the expiration of
such period. For the purposes of this paragraph, the Option or Right shall be
considered assumed if, following the merger or sale of assets, the option or
right confers the right to purchase or receive, for each Share of Optioned Stock
subject to the Option or Right immediately prior to the merger or sale of
assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Common Stock for each
Share held on the effective date of the transaction (and if holders were offered
a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that if such
consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option or Right, for each Share of Optioned
Stock subject to the Option or Right, to be solely common stock of the successor
corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.

     16.  Date of Grant.  The date of grant of an Option or Right shall, for all
          -------------                                                         
purposes, be the date on which the Administrator makes the determination
granting such Option or Right, or such other date as is determined by the Board.
Notice of the determination shall be given to each Employee or Consultant to
whom an Option or Right is so granted within a reasonable time after the date of
such grant.

     17.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a)  Amendment and Termination.  The Board may at any time amend,
               -------------------------                                   
alter, suspend or terminate the Plan.

          (b)  Shareholder Approval.  The Company shall obtain shareholder
               --------------------                                       
approval of any Plan amendment to the extent necessary and desirable to comply
with Rule 16b-3 or with Section 422 of the Code (or any successor rule or
statute or other applicable law, rule or regulation, including the requirements
of any exchange or quotation system on which the Common Stock is listed or
quoted). Such shareholder approval, if required, shall be obtained in such a
manner and to such a degree as is required by the applicable law, rule or
regulation.

          (c)  Effect of Amendment or Termination.  No amendment, alteration,
               ----------------------------------                            
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.

     18.  Conditions Upon Issuance of Shares.  Shares shall not be issued
          ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations 

                                      -12-
<PAGE>
 
promulgated thereunder, and the requirements of any stock exchange upon which
the Shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

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

     19.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------                                             
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

          The inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company's counsel to
be necessary to the lawful issuance and sale of any Shares hereunder, shall
relieve the Company of any liability in respect of the failure to issue or sell
such Shares as to which such requisite authority shall not have been obtained.

     20.  Agreements.  Options shall be evidenced by written agreements in such
          ----------                                                           
form as the Board shall approve from time to time.

     21.  Shareholder Approval.  Continuance of the Plan shall be subject to
          --------------------                                              
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such shareholder approval shall be obtained
in the degree and manner required under applicable state and federal law.

          (a)  An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

          (b)  Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

     6.   Payroll Deductions.
          ------------------ 

          (a)  At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding fifteen percent (15%) of
the Compensation which he or she receives on each pay day during the Offering
Period.

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

          (c)  A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

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

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

     7.   Grant of Option.  On the Enrollment Date of each Offering Period, each
          ---------------                                                       
eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than a
number of shares determined by dividing $12,500 by the Fair Market Value of a
share of the Company's Common Stock on the Enrollment Date, and provided further
that such purchase shall be subject to the limitations set forth in Sections
3(b) and 12 hereof. Exercise of the option shall occur as provided in Section 8
hereof, unless the participant has withdrawn pursuant to Section 10 hereof.  The
option shall expire on the last day of the Offering Period.

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

     9.   Delivery.  As promptly as practicable after each Exercise Date on 
          --------
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

     10.  Withdrawal; Termination of Employment.
          ------------------------------------- 

          (a)  A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at 

                                      -5-
<PAGE>
 
any time by giving written notice to the Company in the form of Exhibit B to
this Plan. All of the participant's payroll deductions credited to his or her
account shall be paid to such participant promptly after receipt of notice of
withdrawal and such participant's option for the Offering Period shall be
automatically terminated, and no further payroll deductions for the purchase of
shares shall be made for such Offering Period. If a participant withdraws from
an Offering Period, payroll deductions shall not resume at the beginning of the
succeeding Offering Period unless the participant delivers to the Company a new
subscription agreement.

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

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

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

     12.  Stock.
          ----- 

          (a)  The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be five hundred thousand
(500,000) shares, subject to adjustment upon changes in capitalization of the
Company as provided in Section 18 hereof. If, on a given Exercise Date, the
number of shares with respect to which options are to be exercised exceeds the
number of shares then available under the Plan, the Company shall make a pro
rata allocation of the shares remaining available for purchase in as uniform a
manner as shall be practicable and as it shall determine to be equitable.

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

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

     13.  Administration.
          -------------- 

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

          (b)  Rule 16b-3 Limitations.  Notwithstanding the provisions of 
               ----------------------
Subsection (a) of this Section 13, in the event that Rule 16b-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
any successor provision ("Rule 16b-3") provides specific requirements for the
administrators of plans of this type, the Plan shall be administered only by
such a body and in such a manner as shall comply with the applicable
requirements of Rule 16b-3. Unless permitted by Rule 16b-3, no discretion
concerning decisions regarding the Plan shall be afforded to any committee or
person that is not "disinterested" as that term is used in Rule 16b-3.

     14.  Designation of Beneficiary.
          -------------------------- 

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

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

     15.  Transferability.  Neither payroll deductions credited to a
          ---------------                                           
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the participant.  Any such

                                      -7-
<PAGE>
 
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

     16.  Use of Funds.  All payroll deductions received or held by the Company
          ------------

Company shall not be obligated to segregate such payroll deductions.

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

shareholders of the Company, the Reserves, as well as the price per share and
the number of shares of Common Stock covered by each option under the Plan which
has not yet been exercised, shall be proportionately adjusted for any increase
or decrease in the number of issued shares of Common Stock resulting from a
stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration".  Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive.  Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an option.

          (b)  Dissolution or Liquidation.  In the event of the proposed 
               --------------------------
dissolution or liquidation of the Company, the Offering Periods shall terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

          (c)  Merger or Asset Sale.  In the event of a proposed sale of all or
               --------------------                                            
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, any Purchase Periods then in progress shall be
shortened by setting a new Exercise Date (the "New Exercise Date") and any
Offering Periods then in progress shall end on the New Exercise Date.  The New
Exercise Date shall be before the date of the Company's proposed sale or merger.
The Board shall notify each participant in writing, at least ten (10) business
days prior to the New Exercise Date, that the Exercise Date for the
participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised 

                                      -8-
<PAGE>
 
automatically on the New Exercise Date, unless prior to such date the
participant has withdrawn from the Offering Period as provided in Section 10
hereof.

     19.  Amendment or Termination.
          ------------------------ 

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

          (b)  Without shareholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

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

     21.  Conditions Upon Issuance of Shares.  Shares shall not be issued with
          ----------------------------------                                  
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

                                      -9-
<PAGE>
 
          As a condition to the exercise of an option, the Company may require
the person exercising such option to represent and warrant at the time of any
such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

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

     23.  Automatic Transfer to Low Price Offering Period.  To the extent
          -----------------------------------------------                
permitted by Rule 16b-3 of the Exchange Act, if the Fair Market Value of the
Common Stock on any Exercise Date in an Offering Period is lower than the Fair
Market Value of the Common Stock on the Enrollment Date of such Offering Period,
then all participants in such Offering Period shall be automatically withdrawn
from such Offering Period immediately after the exercise of their option on such
Exercise Date and automatically re-enrolled in the immediately following
Offering Period as of the first day thereof.

                             SUBSCRIPTION AGREEMENT



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


1.   _____________________________________________________ hereby elects to
     participate in the Interlink Computer Sciences, Inc. 1996 Employee Stock
     Purchase Plan (the "Employee Stock Purchase Plan") and subscribes to
     purchase shares of the Company's Common Stock in accordance with this
     Subscription Agreement and the Employee Stock Purchase Plan.

2.   I hereby authorize payroll deductions from each paycheck in the amount of
     ____% of my Compensation on each payday (from 1 to 15%) during the Offering
     Period in accordance with the Employee Stock Purchase Plan. (Please note
     that no fractional percentages are permitted.)

3.   I understand that said payroll deductions shall be accumulated for the
     purchase of shares of Common Stock at the applicable Purchase Price
     determined in accordance with the Employee Stock Purchase Plan. I
     understand that if I do not withdraw from an Offering Period, any
     accumulated payroll deductions will be used to automatically exercise my
     option.

4.   I have received a copy of the complete Employee Stock Purchase Plan. I
     understand that my participation in the Employee Stock Purchase Plan is in
     all respects subject to the terms of the Plan. I understand that my ability
     to exercise the option under this Subscription Agreement is subject to
     shareholder approval of the Employee Stock Purchase Plan.

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

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

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

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

               (iii) Each Outside Director shall be automatically granted an
Option to purchase 2,500 Shares (a "Subsequent Option") on the date of his or

                    (D) subject to Section 10 hereof, the Subsequent Option
shall become exercisable as to 100% of the Shares subject to the Subsequent
Option on the fourth anniversary of its date of grant, provided that the
Optionee continues to serve as a Director on such dates.

               (vii) In the event that any Option granted under the Plan would
cause the number of Shares subject to outstanding Options plus the number of
Shares previously purchased under Options to exceed the Pool, then the remaining
Shares available for Option grant shall be granted under Options to the Outside
Directors on a pro rata basis. No further grants shall be made until such time,
if any, as additional Shares become available for grant under the Plan through
action of the Board or the shareholders to increase the number of Shares which
may be issued under the Plan or through cancellation or expiration of Options
previously granted hereunder.

     5.   Eligibility.  Options may be granted only to Outside Directors.  All
          -----------                                                         
Options shall be automatically granted in accordance with the terms set forth in
Section 4 hereof.

          The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director, nor
shall it interfere in any way with any rights which the Director or the Company
may have to terminate the Director's relationship with the Company at any time.

     6.   Term of Plan.  The Plan shall become effective upon the earlier to
          ------------                                                      
occur of its adoption by the Board or its approval by the shareholders of the
Company as described in Section 16 of the Plan.  It shall continue in effect for
a term of ten (10) years unless sooner terminated under Section 11 of the Plan.

     7.   Form of Consideration.  The consideration to be paid for the Shares to
          ---------------------                                                 
be issued upon exercise of an Option, including the method of payment, shall
consist of (i) cash, (ii) check, (iii) other shares which (x) in the case of
Shares acquired upon exercise of an Option, have been owned by the Optionee for
more than six (6) months on the date of surrender, and (y) have a Fair Market
Value on the date of surrender equal to the aggregate exercise price of 

                                      -4-
<PAGE>
 
the Shares as to which said Option shall be exercised, (iv) delivery of a
properly executed exercise notice together with such other documentation as the
Company and the broker, if applicable, shall require to effect an exercise of
the Option and delivery to the Company of the sale or loan proceeds required to
pay the exercise price, or (v) any combination of the foregoing methods of
payment.

     8.   Exercise of Option.
          ------------------ 

          (a)  Procedure for Exercise; Rights as a Shareholder. Any Option 
               -----------------------------------------------
granted hereunder shall be exercisable at such times as are set forth in Section
4 hereof; provided, however, that no Options shall be exercisable until
shareholder approval of the Plan in accordance with Section 16 hereof has been
obtained.

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

          An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may consist of any consideration and method of payment
allowable under Section 7 of the Plan.  Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company) of the stock certificate evidencing such Shares, no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
A share certificate for the number of Shares so acquired shall be issued to the
Optionee as soon as practicable after exercise of the Option. No adjustment
shall be made for a dividend or other right for which the record date is prior
to the date the stock certificate is issued, except as provided in Section 10 of
the Plan.

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

          (b)  Rule 16b-3.  Options granted to Outside Directors must comply 
               ----------
with the applicable provisions of Rule 16b-3 promulgated under the Exchange Act
or any successor thereto and shall contain such additional conditions or
restrictions as may be required thereunder to qualify Plan transactions, and
other transactions by Outside Directors that otherwise could be matched with
Plan transactions, for the maximum exemption from Section 16 of the Exchange
Act.

          (c)  Termination of Continuous Status as a Director.  Subject to 
               ----------------------------------------------
Section 10 hereof, in the event an Optionee's status as a Director terminates
(other than upon the Optionee's death or total and permanent disability (as
defined in Section 22(e)(3) of the Code)), the Optionee may exercise his or her
Option, but only within three (3) months following the date of such termination,
and only to the extent that the Optionee was entitled to exercise it on the date

                                      -5-
<PAGE>
 
of such termination (but in no event later than the expiration of its ten (10)
year term). To the extent that the Optionee was not entitled to exercise an
Option on the date of such termination, and to the extent that the Optionee does
not exercise such Option (to the extent otherwise so entitled) within the time
specified herein, the Option shall terminate.

          (d)  Disability of Optionee.  In the event Optionee's status as a 
               ----------------------
Director terminates as a result of total and permanent disability (as defined in
Section 22(e)(3) of the Code), the Optionee may exercise his or her Option, but
only within twelve (12) months following the date of such ter mination, and only
to the extent that the Optionee was entitled to exercise it on the date of such
termination (but in no event later than the expiration of its ten (10) year
term). To the extent that the Optionee was not entitled to exercise an Option on
the date of termination, or if he or she does not exercise such Option (to the
extent otherwise so entitled) within the time specified herein, the Option shall
terminate.

          (e)  Death of Optionee.  In the event of an Optionee's death, the 
               -----------------
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term). To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

     9.   Non-Transferability of Options.  The Option may not be sold, pledged,
          ------------------------------                                       
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

     10.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
          ------------------------------------------------------------------
          Asset Sale.
          ---------- 

          (a)  Changes in Capitalization.  Subject to any required action by the
               -------------------------                                        
shareholders of the Company, the number of Shares covered by each outstanding
Option, the number of Shares which have been authorized for issuance under the
Plan but as to which no Options have yet been granted or which have been
returned to the Plan upon cancellation or expiration of an Option, as well as
the price per Share covered by each such outstanding Option, and the number of
Shares issuable pursuant to the automatic grant provisions of Section 4 hereof
shall be proportionately adjusted for any increase or decrease in the number of
issued Shares resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued Shares effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and 

                                      -6-
<PAGE>
 
no adjustment by reason thereof shall be made with respect to, the number or
price of Shares subject to an Option.

          (b)  Dissolution or Liquidation.  In the event of the proposed 
               --------------------------
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it shall terminate immediately prior to the
consummation of such proposed action.

          (c)  Merger or Asset Sale.  In the event of a merger of the Company 
               --------------------
with or into another corporation or the sale of substantially all of the assets
of the Company, outstanding Options may be assumed or equivalent options may be
substituted by the successor corporation or a Parent or Subsidiary thereof (the
"Successor Corporation"). If an Option is assumed or substituted for, the Option
or equivalent option shall continue to be exercisable as provided in Section 4
hereof for so long as the Optionee serves as a Director or a director of the
Successor Corporation. Following such assumption or substitution, if the
Optionee's status as a Director or director of the Successor Corporation, as
applicable, is terminated other than upon a voluntary resignation by the
Optionee, the Option or option shall become fully exercisable, including as to
Shares for which it would not otherwise be exercisable. Thereafter, the Option
or option shall remain exercisable in accordance with Sections 8(c) through (e)
above.

     If the Successor Corporation does not assume an outstanding Option or
substitute for it an equivalent option, the Option shall become fully vested and
exercisable, including as to Shares for which it would not otherwise be
exercisable.  In such event the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of thirty (30) days from the date of
such notice, and upon the expiration of such period the Option shall terminate.

     For the purposes of this Section 10(c), an Option shall be considered
assumed if, following the merger or sale of assets, the Option confers the right
to purchase or receive, for each Share of Optioned Stock subject to the Option
immediately prior to the merger or sale of assets, the consideration (whether
stock, cash, or other securities or property) received in the merger or sale of
assets by holders of Common Stock for each Share held on the effective date of
the transaction (and if holders were offered a choice of consideration, the type
of consideration chosen by the holders of a majority of the outstanding Shares).
If such consideration received in the merger or sale of assets is not solely
common stock of the successor corporation or its Parent, the Administrator may,
with the consent of the successor corporation, provide for the consideration to
be received upon the exercise of the Option, for each Share of Optioned Stock
subject to the Option, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

     11.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a)  Amendment and Termination.  Except as set forth in Section 4, 
               -------------------------
the Board may at any time amend, alter, suspend, or discontinue the Plan, but no
amendment, alteration, suspension, or discontinuation shall be made which would
impair the rights of any Optionee 

                                      -7-
<PAGE>
 
under any grant theretofore made, without his or her consent. In addition, to
the extent necessary and desirable to comply with Rule 16b-3 under the Exchange
Act (or any other applicable law or regulation), the Company shall obtain
shareholder approval of any Plan amendment in such a manner and to such a degree
as required.

          (b)  Effect of Amendment or Termination.  Any such amendment or 
               ----------------------------------
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated.

     12.  Time of Granting Options.  The date of grant of an Option shall, for
          ------------------------                                            
all purposes, be the date determined in accordance with Section 4 hereof.

     13.  Conditions Upon Issuance of Shares.  Shares shall not be issued
          ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated there
under, state securities laws, and the requirements of any stock exchange upon
which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

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

          Inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.

     14.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------                                             
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     15.  Option Agreement.  Options shall be evidenced by written option
          ----------------                                               
agreements in such form as the Board shall approve.

     16.  Shareholder Approval.  Continuance of the Plan shall be subject to
          --------------------                                              
approval by the shareholders of the Company at or prior to the first annual
meeting of shareholders held subsequent to the granting of an Option hereunder.
Such shareholder approval shall be obtained in the degree and manner required
under applicable state and federal law.

                       INTERLINK COMPUTER SCIENCES, INC.

                           INDEMNIFICATION AGREEMENT

     This Indemnification Agreement ("Agreement") is effective as of
_______________, 1996 by and between Interlink Computer Sciences, Inc., a
Delaware corporation (the "Company"), and ___________________________________,
("Indemnitee").

     WHEREAS, the Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and its related
entities;

     WHEREAS, in order to induce Indemnitee to continue to provide services to
the Company, the Company wishes to provide for the indemnification of, and the
advancement of expenses to, Indemnitee to the maximum extent permitted by law;

     WHEREAS, the Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for the Company's directors, officers, employees,
agents and fiduciaries, the sig nificant increases in the cost of such insurance
and the general reductions in the coverage of such insurance;

     WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting directors, officers,
employees, agents and fiduciaries to expensive litigation risks at the same time
as the availability and coverage of liability insurance has been severely
limited; and

     WHEREAS, in connection with the Company's reincorporation, the Company and
Indemnitee desire to continue to have in place the additional protection
provided by an indemnification agreement to provide indemnification and
advancement of expenses to the Indemnitee to the maximum extent permitted by
Delaware law;

     WHEREAS, in view of the considerations set forth above, the Company desires
that Indemnitee shall be indemnified and advanced expenses by the Company as set
forth herein;

     NOW, THEREFORE, the Company and Indemnitee hereby agree as set forth below.

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

          (a)  "Change in Control" shall mean, and shall be deemed to have
occurred if, on or after the date of this Agreement, (i) any "person" (as such
term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934,
as amended) or group acting in concert, other than a trustee or other fiduciary
holding securities under an employee benefit plan of the Company acting in such
capacity or a corporation owned directly or indirectly by the stockholders of
the Company in substantially the same proportions as their ownership of stock of
the Company, becomes the "beneficial owner" (as defined in Rule 13d-3 under said
Act), directly or indirectly, of securities of the Company representing more
than 50% of the total voting power represented by the Company's then outstanding
Voting Securities, (ii) during any period of two 
<PAGE>
 
consecutive years, individuals who at the beginning of such period constitute

Board of Directors or nomination for election by the Company's stockholders was
approved by a vote of at least two thirds (2/3) of the directors then still in
office who either were directors at the beginning of the period or whose
election or nomination for election was previously so approved, cease for any
reason to constitute a majority thereof, (iii) the stockholders of the Company
approve a merger or consolidation of the Company with any other corporation
other than a merger or consolidation which would result in the Voting Securities
of the Company outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into Voting Securities of
the surviving entity) at least 80% of the total voting power represented by the
Voting Securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or (iv) the stockholders of the
Company approve a plan of complete liquidation of the Company or an agreement

administrative, investigative or other.

          (c) References to the "Company" shall include, in addition to
Interlink Computer Sciences, Inc., any constituent corporation (including any
constituent of a constituent) absorbed in a consolidation or merger to which
Interlink Computer Sciences, Inc. (or any of its wholly owned subsidiaries) is a
party which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, employees, agents or
fiduciaries, so that if Indemnitee is or was a director, officer, employee,
agent or fiduciary of such constituent corporation, or is or was serving at the
request of such constituent corporation as a director, officer, employee, agent
or fiduciary of another corporation, partnership, joint venture, employee
benefit plan, trust or other enterprise, Indemnitee shall stand in the same

surviving corporation as Indemnitee would have with respect to such constituent
corporation if its separate existence had continued.

          (d) "Covered Event" shall mean any event or occurrence related to the
fact that Indemnitee is or was a director, officer, employee, agent or fiduciary
of the Company, or any subsidiary of the Company, or is or was serving at the
request of the Company as a director, officer, employee, agent or fiduciary of
another corporation, partnership, joint venture, trust or other enterprise, or

the actual or deemed receipt of any payments under this Agreement.

          (f) "Expense Advance" shall mean a payment to Indemnitee pursuant to
Section 3 of Expenses in advance of the settlement of or final judgement in any
action, suit, proceeding or alternative dispute resolution mechanism, hearing,
inquiry or investigation which constitutes a Claim.

          (g) "Independent Legal Counsel" shall mean an attorney or firm of
attorneys, selected in accordance with the provisions of Section 2(d) hereof,
who shall not have otherwise performed services for the Company or Indemnitee

be in the interest of the participants and beneficiaries of an employee benefit

best interests of the Company"  as referred to in this Agreement.

          (i) "Reviewing Party" shall mean, subject to the provisions of Section
2(d), any person or body appointed by the Board of Directors in accordance with
applicable law to review the Company's obligations hereunder and under
applicable law, which may include a member or members of the Company's Board of
Directors, Independent Legal Counsel or any other person or body not a party to

          (j) "Section" refers to a section of this Agreement unless otherwise
indicated.

          (k) "Voting Securities" shall mean any securities of the Company that
vote generally in the election of directors.

     2.   Indemnification.
          --------------- 

          (a)  Indemnification of Expenses.  Subject to the provisions of 
               ---------------------------
Section 2(b) below, the Company shall indemnify Indemnitee for Expenses to the
fullest extent permitted by law if Indemnitee was or is or becomes a party to or
witness or other participant in, or is threatened to be made a party to or
witness or other participant in, any Claim (whether by reason of or arising in
part out of a Covered Event), including all interest, assessments and other
charges 

                                      -3-
<PAGE>
 
paid or payable in connection with or in respect of such Expenses.

          (b)  Review of Indemnification Obligations.  Notwithstanding the
               -------------------------------------                      
foregoing, in the event any Reviewing Party shall have determined (in a written
opinion, in any case in which Independent Legal Counsel is the Reviewing Party)
that Indemnitee is not entitled to be indemnified hereunder under applicable
law, (i) the Company shall have no further obligation under Section 2(a) to make
any payments to Indemnitee not made prior to such determination by such
Reviewing Party, and (ii) the Company shall be entitled to be reimbursed by
Indemnitee (who hereby agrees to reimburse the Company) for all Expenses
theretofore paid to Indemnitee to which Indemnitee is not entitled hereunder
under applicable law; provided, however, that if Indemnitee has commenced or
                      --------  -------                                     
thereafter commences legal proceedings in a court of competent jurisdiction to
secure a determination that Indemnitee is entitled to be indemnified hereunder
under applicable law, any determination made by any Reviewing Party that
Indemnitee is not entitled to be indemnified hereunder under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expenses theretofore paid in indemnifying Indemnitee until a
final judicial determination is made with respect thereto (as to which all
rights of appeal therefrom have been exhausted or lapsed). Indemnitee's
obligation to reimburse the Company for any Expenses shall be unsecured and no
interest shall be charged thereon.

          (c)  Indemnitee Rights on Unfavorable Determination; Binding Effect.
               --------------------------------------------------------------  
If any Reviewing Party determines that Indemnitee substantively is not entitled
to be indemnified hereunder in whole or in part under applicable law, Indemnitee
shall have the right to commence litigation seeking an initial determination by
the court or challenging any such determination by such Reviewing Party or any
aspect thereof, including the legal or factual bases therefor, and, subject to
the provisions of Section 15, the Company hereby consents to service of process
and to appear in any such proceed ing.  Absent such litigation, any
determination by any Reviewing Party shall be conclusive and binding on the
Company and Indemnitee.

          (d)  Selection of Reviewing Party; Change in Control.  If there has 
               -----------------------------------------------
not been a Change in Control, any Reviewing Party shall be selected by the Board
of Directors, and if there has been such a Change in Control (other than a
Change in Control which has been approved by a majority of the Company's Board
of Directors who were directors immediately prior to such Change in Control),
any Reviewing Party with respect to all matters thereafter arising concerning
the rights of Indemnitee to indemnification of Expenses under this Agreement or
any other agreement or under the Company's Certificate of Incorporation or
Bylaws as now or hereafter in effect, or under any other applicable law, if
desired by Indemnitee, shall be Independent Legal Counsel selected by Indemnitee
and approved by the Company (which approval shall not be unreasonably withheld).
Such counsel, among other things, shall render its written opinion to the
Company and Indemnitee as to whether and to what extent Indemnitee would be
entitled to be indemnified hereunder under applicable law and the Company agrees
to abide by such opinion. The Company agrees to pay the reasonable fees of the
Independent Legal Counsel referred to above and to indemnify fully such counsel
against any and all expenses (including attorneys' fees), claims, liabilities
and damages arising out of or relating to this Agreement or its 

                                      -4-

engagement pursuant hereto. Notwithstanding any other provision of this
Agreement, the Company shall not be required to pay Expenses of more than one
Independent Legal Counsel in connection with all matters concerning a single
Indemnitee, and such Independent Legal Counsel shall be the Independent Legal
Counsel for any or all other Indemnitees unless (i) the employment of separate
counsel by one or more Indemnitees has been previously authorized by the Company
in writing, or (ii) an Indemnitee shall have provided to the Company a written
statement that such Indemnitee has reasonably concluded that there may be a
conflict of interest between such Indemnitee and the other Indemnitees with
respect to the matters arising under this Agreement.

          (e)  Mandatory Payment of Expenses.  Notwithstanding any other
               -----------------------------                            
provision of this Agreement other than Section 10 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
Claim, Indemnitee shall be indemnified against all Expenses incurred by
Indemnitee in connection therewith.

     3.   Expense Advances.
          ---------------- 

          (a)  Obligation to Make Expense Advances.  Upon receipt of a written
               -----------------------------------                            
undertaking by or on behalf of the Indemnitee to repay such amounts if it shall
ultimately be determined that the Indemnitee is not entitled to be indemnified
therefore by the Company hereunder under applicable law, the Company shall make
Expense Advances to Indemnitee.

          (b)  Form of Undertaking.  Any obligation to repay any Expense 
               -------------------
Advances hereunder pursuant to a written undertaking by the Indemnitee shall be
unsecured and no interest shall be charged thereon.

          (c)  Determination of Reasonable Expense Advances.  The parties agree
               --------------------------------------------                    
that for the purposes of any Expense Advance for which Indemnitee has made
written demand to the Company in accordance with this Agreement, all Expenses
included in such Expense Advance that are certified by affidavit of Indemnitee's
counsel as being reasonable shall be presumed conclusively to be reasonable.

     4.   Procedures for Indemnification and Expense Advances.
          --------------------------------------------------- 

          (a)  Timing of Payments.  All payments of Expenses (including without
               ------------------                                              
limitation Expense Advances) by the Company to the Indemnitee pursuant to this
Agreement shall be made to the fullest extent permitted by law as soon as
practicable after written demand by Indemnitee therefor is presented to the
Company, but in no event later than thirty (30) business days after such written
demand by Indemnitee is presented to the Company, except in the case of Expense
Advances, which shall be made no later than ten (10) business days after such
written demand by Indemnitee is presented to the Company.

          (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a 
               --------------------------------                         
condition 

                                      -5-
<PAGE>
 
precedent to Indemnitee's right to be indemnified or Indemnitee's right to
receive Expense Advances under this Agreement, give the Company notice in
writing as soon as practicable of any Claim made against Indemnitee for which
indemnification will or could be sought under this Agreement. Notice to the
Company shall be directed to the Chief Executive Officer of the Company at the
address shown on the signature page of this Agreement (or such other address as
the Company shall designate in writing to Indemnitee). In addition, Indemnitee
shall give the Company such information and cooperation as it may reasonably
require and as shall be within Indemnitee's power.

          (c)  No Presumptions; Burden of Proof.  For purposes of this 
               --------------------------------
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo
                                                                 ----
contendere, or its equivalent, shall not create a presumption that
- ----------
Indemnitee did not meet any particular standard of conduct or have any
particular belief or that a court has determined that indemnification is not
permitted by this Agreement or applicable law. In addition, neither the failure
of any Reviewing Party to have made a determination as to whether Indemnitee has
met any particular standard of conduct or had any particular belief, nor an
actual determination by any Reviewing Party that Indemnitee has not met such
standard of conduct or did not have such belief, prior to the commencement of
legal proceedings by Indemnitee to secure a judicial determination that
Indemnitee should be indemnified under this Agreement under applicable law,
shall be a defense to Indemnitee's claim or create a presumption that Indemnitee
has not met any particular standard of conduct or did not have any particular
belief. In connection with any determination by any Reviewing Party or
otherwise as to whether the Indemnitee is entitled to be indemnified hereunder
under applicable law, the burden of proof shall be on the Company to establish
that Indemnitee is not so entitled.

          (d)  Notice to Insurers.  If, at the time of the receipt by the 
               ------------------
Company of a notice of a Claim pursuant to Section 4(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim 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 Claim in
accordance with the terms of such policies.

          (e)  Selection of Counsel.  In the event the Company shall be 
               --------------------
obligated hereunder to provide indemnification for or make any Expense Advances
with respect to the Expenses of any Claim, the Company, if appropriate, shall be
entitled to assume the defense of such Claim with counsel approved by Indemnitee
(which approval shall not be unreasonably withheld) upon the delivery to
Indemnitee of written notice of the Company's election to do so. After delivery
of such notice, approval of such counsel by Indemnitee and the retention of such
counsel by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees or expenses of separate counsel subsequently retained by
or on behalf of Indemnitee with respect to the same Claim; provided that, (i)
Indemnitee shall have the right to employ Indemnitee's separate counsel in any
such Claim at Indemnitee's expense and (ii) if (A) the employment of separate
counsel by Indemnitee has been previously authorized by the Company, 

                                      -6-
<PAGE>
 
(B) Indemnitee shall have reasonably concluded that there may be a conflict of
interest between the Company and Indemnitee in the conduct of any such defense,
or (C) the Company shall not continue to retain such counsel to defend such
Claim, then the fees and expenses of Indemnitee's separate counsel shall be
Expenses for which Indemnitee may receive indemnification or Expense Advances
hereunder.

     5.   Additional Indemnification Rights; Nonexclusivity.
          ------------------------------------------------- 

          (a)  Scope.  The Company hereby agrees to indemnify the Indemnitee to
               -----                                                           
the fullest extent permitted by law, notwithstanding that such indemnification
is not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws or by statute.  In
the event of any change after the date of this Agreement in any applicable law,
statute or rule which expands the right of a Delaware corporation to indemnify a
member of its board of directors or an officer, employee, agent or fiduciary, it
is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits afforded by such change.  In the event of any
change in any applicable law, statute or rule which narrows the right of a
Delaware corporation to indemnify a member of its board of directors or an
officer, employee, agent or fiduciary, such change, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement, shall
have no effect on this Agreement or the parties' rights and obligations
hereunder except as set forth in Section 10(a) hereof.

          (b)  Nonexclusivity.  The indemnification and the payment of Expense
               --------------                                                 
Advances provided by this Agreement shall be in addition to any rights to which
Indemnitee may be entitled under the Company's Certificate of Incorporation, its
Bylaws, any other agreement, any vote of stockholders or disinterested
directors, the General Corporation Law of the State of Delaware, or otherwise.
The indemnification and the payment of Expense Advances provided under this
Agreement shall continue as to Indemnitee for any action taken or not taken
while serving in an indemnified capacity even though subsequent thereto
Indemnitee may have ceased to serve in such capacity.

     6.   No Duplication of Payments.  The Company shall not be liable under
          --------------------------                                        
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, provision of the Company's Certificate of
Incorporation, Bylaws or otherwise) of the amounts otherwise payable hereunder.

     7.   Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------                                      
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

     8.   Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
          ---------------------                                              
that in certain instances, federal law or applicable public policy may prohibit
the Company from 

                                      -7-
<PAGE>
 
indemnifying its directors, officers, employees, agents or fiduciaries under
this Agreement or otherwise. Indemnitee understands and acknowledges that the
Company has undertaken or may be required in the future to undertake with the
Securities and Exchange Commission to submit the question of indemnification to
a court in certain circumstances for a determination of the Company's right
under public policy to indemnify Indemnitee.

     9.   Liability Insurance.  To the extent the Company maintains liability
          -------------------                                                
insurance applicable to directors, officers, employees, agents or fiduciaries,
Indemnitee shall be covered by such policies in such a manner as to provide
Indemnitee the same rights and benefits as are provided to the most favorably
insured of the Company's directors, if Indemnitee is a director; or of the
Company's officers, if Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, agents or fiduciaries, if Indemnitee
is not an officer or director but is a key employee, agent or fiduciary.

     10.  Exceptions.  Notwithstanding any other provision of this Agreement,
          ----------                                                         
the Company shall not be obligated pursuant to the terms of this Agreement:

          (a)  Excluded Action or Omissions.  To indemnify or make Expense
               ----------------------------                               
Advances to Indemnitee with respect to Claims arising out of acts, omissions or
transactions for which Indemnitee is prohibited from receiving indemnification
under applicable law.

          (b)  Claims Initiated by Indemnitee.  To indemnify or make Expense
               ------------------------------                               
Advances to Indemnitee with respect to Claims initiated or brought voluntarily
by Indemnitee and not by way of defense, counterclaim or crossclaim, except (i)
with respect to actions or proceedings brought to establish or enforce a right
to indemnification under this Agreement or any other agreement or insurance
policy or under the Company's Certificate of Incorporation or Bylaws now or
hereafter in effect relating to Claims for Covered Events, (ii) in specific
cases if the Board of Directors has approved the initiation or bringing of such
Claim, or (iii) as otherwise required under Section 145 of the Delaware General
Corporation Law, regardless of whether Indemnitee ultimately is determined to be
entitled to such indemnification, Expense Advances, or insurance recovery, as
the case may be.

          (c)  Lack of Good Faith.  To indemnify Indemnitee for any Expenses
               ------------------                                           
incurred by the Indemnitee with respect to any action instituted (i) by
Indemnitee to enforce or interpret this Agreement, if a court having
jurisdiction over such action determines as provided in Section 13 that each of
the material assertions made by the Indemnitee as a basis for such action was
not made in good faith or was frivolous, or (ii) by or in the name of the
Company to enforce or interpret this Agreement, if a court having jurisdiction
over such action determines as provided in Section 13 that each of the material
defenses asserted by Indemnitee in such action was made in bad faith or was
frivolous.

          (d)  Claims Under Section 16(b).  To indemnify Indemnitee for Expenses
               --------------------------                                       
and the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation 

                                      -8-
<PAGE>
 
of Section 16(b) of the Securities Exchange Act of 1934, as amended, or any
similar successor statute.

     11.  Counterparts.  This Agreement may be executed in one or more
          ------------                                                
counterparts, each of which shall constitute an original.

     12.  Binding Effect; Successors and Assigns.  This Agreement shall be
          --------------------------------------                          
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns (including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business or assets of the Company), spouses, heirs and
personal and legal representatives.  The Company shall require and cause any
successor (whether direct or indirect, and whether by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part, of
the business or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place.  This Agreement
shall continue in effect regardless of whether Indemnitee continues to serve as
a director, officer, employee, agent or fiduciary (as applicable) of the Company
or of any other enterprise at the Company's request.

     13.  Expenses Incurred in Action Relating to Enforcement or Interpretation.
          --------------------------------------------------------------------- 
In the event that any action is instituted by Indemnitee under this Agreement or
under any liability insurance policies maintained by the Company to enforce or
interpret any of the terms hereof or thereof, Indemnitee shall be entitled to be
indemnified for all Expenses incurred by Indemnitee with respect to such action
(including without limitation attorneys' fees), regardless of whether Indemnitee
is ulti mately successful in such action, unless as a part of such action a
court having jurisdiction over such action makes a final judicial determination
(as to which all rights of appeal therefrom have been exhausted or lapsed) that
each of the material assertions made by Indemnitee as a basis for such action
was not made in good faith or was frivolous; provided, however, that until such
final judicial determination is made, Indemnitee shall be entitled under Section
3 to receive payment of Expense Advances hereunder with respect to such action.
In the event of an action instituted by or in the name of the Company under this
Agreement to enforce or interpret any of the terms of this Agreement, Indemnitee
shall be entitled to be indemnified for all Expenses incurred by Indemnitee in
defense of such action (including without limitation costs and expenses incurred
with respect to Indemnitee's counterclaims and cross-claims made in such
action), unless as a part of such action a court having jurisdiction over such
action makes a final judicial determination (as to which all rights of appeal
therefrom have been exhausted or lapsed) that each of the material defenses
asserted by Indemnitee in such action was made in bad faith or was frivolous;
provided, however, that until such final judicial determination is made,
Indemnitee shall be entitled under Section 3 to receive payment of Expense
Advances hereunder with respect to such action.

     14.  Period of Limitations.  No legal action shall be brought and no cause
          ---------------------                                                
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from 

                                      -9-
<PAGE>
 
the date of accrual of such cause of action, and any claim or cause of action of
the Company shall be extinguished and deemed released unless asserted by the
timely filing of a legal action within such two year period; provided, however,
                                                             --------  -------
that if any shorter period of limitations is otherwise applicable to any such
cause of action, such shorter period shall govern.

     15.  Notice.  All notices, requests, demands and other communications under
          ------                                                                
this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and signed for by the party addressed, on the date of such
delivery, or (ii) if mailed by domestic certified or registered mail with
postage prepaid, on the third business day after the date postmarked.  Addresses
for notice to either party are as shown on the signature page of this Agreement,
or as subsequently modified by written notice.

     16.  Consent to Jurisdiction.  The Company and Indemnitee each hereby
          -----------------------                                         
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum for adjudicating such a claim.

     17.  Severability.  The provisions of this Agreement shall be severable in
          ------------                                                         
the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including without limitation each portion of this Agreement containing any
provision held to be invalid, void or otherwise unenforceable, that is not
itself invalid, void or unenforceable) shall be construed so as to give effect
to the intent manifested by the provision held invalid, illegal or
unenforceable.

     18.  Choice of Law.  This Agreement, and all rights, remedies, liabilities,
          -------------                                                         
powers and duties of the parties to this Agreement, shall be governed by and
construed in accordance with the laws of the State of Delaware as applied to
contracts between Delaware residents entered into and to be performed entirely
in the State of Delaware without regard to principles of conflicts of laws.

     19.  Subrogation.  In the event of payment under this Agreement, the
          -----------                                                    
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

     20.  Amendment and Termination.  No amendment, modification, termination or
          -------------------------                                             
cancellation of this Agreement shall be effective unless it is in writing signed
by both the parties hereto. No waiver of any of the provisions of this Agreement
shall be deemed to be or shall

                                      -10-
<PAGE>
 
constitute a waiver of any other provisions hereof (whether or not similar), nor
shall such waiver constitute a continuing waiver.

     21.  Integration and Entire Agreement.  This Agreement sets forth the
          --------------------------------                                
entire understanding between the parties hereto and supersedes and merges all
previous written and oral negotiations, commitments, understandings and
agreements relating to the subject matter hereof between the parties hereto.

     22.  No Construction as Employment Agreement.  Nothing contained in this
          ---------------------------------------                            
Agreement shall be construed as giving Indemnitee any right to be retained in
the employ of the Company or any of its subsidiaries or affiliated entities.

     IN WITNESS WHEREOF, the parties hereto have executed this Indemnification
Agreement as of the date first above written.

     ----
term stated in the Lease Summary, in accordance with the following:
     3.1. Commencement. The commencement date shall be the Commencement Date
          ------------
stated in the Lease Summary or, if no Commencement Date is stated, the earlier
of (i) the date of substantial completion of the improvements to be constructed
by Landlord on the Premises, according to any description of Landlord work set
forth on an Exhibit or Addendum to this Lease, or (ii) the date on which Tenant
first uses a portion of the Premises in its business. "Substantial completion"
shall have occurred on the first date on which (i) the governmental authority
having jurisdiction has authorized occupancy of the Premises, (ii) electric
power is available at the Premises, and (iii) the architect, engineer, or other
person supervising construction of the improvements certifies that they are
substantially complete and ready for occupancy, subject only to "punch-list"
defects that do not materially diminish the usefulness of the Premises. Landlord
shall advise Tenant, from time to time and in good faith, of the estimated
completion date. Upon ascertaining the commencement date, the parties shall
insert that date in the Lease Summary, as the "Commencement Date," and initial
the insertion. If the commencement date is other than the first day of a
calendar month, then the lease term shall extend for the number of months stated
in the Lease Summary, beginning with the first day of the month following the
commencement date.
     3.2. Postponement. If, for any reason, Landlord is unable to deliver
          ------------
possession of the Premises to Tenant on a Commencement Date stated in the Lease
Summary, the commencement of the lease term will be postponed, without
liability to either party or affecting the validity of this Lease, and the term
shall begin on such date as Landlord is able to deliver possession. However, if
Landlord is unable to deliver possession then this Lease shall thereupon
terminate without liability to either party.

Landlord when due shall thereafter bear interest, at the rate stated in
paragraph 17.1, until received, provided that Landlord will waive interest on
any monthly rental payment received not later than the fifth day of that month
(or the first business day following the fifth if the fifth falls on a weekend
or holiday). All such sums shall be paid to Landlord at Menlo Park, California,
or such other place in California as Landlord may designate.
     4.1. Base Monthly Rent. The base monthly rent shall be the amount stated in
          -----------------
the Lease Summary, payable in monthly installments in advance, on the first day
of each calendar month during the lease term. If the commencement date is a day

month shall be a fraction of the base monthly rent, based on the number of days
in that partial month, including the commencement date, in proportion to the
total number of days in the month; such rent shall be payable on the first day
of the following month. Rent for the first calendar month of the term is payable
upon execution of this Lease.

Lease, the sum stated in the Lease Summary as the security deposit, which
Landlord shall retain the sum stated in the Lease Summary as the security
deposit, which Landlord shall retain as a debtor and not as a trustee. Tenant
acknowledges that the use value of the security deposit has been considered in
determining the appropriate monthly rent for the Premises, and Tenant shall be
entitled to no credit or compensation, by way of interest or otherwise, for
Landlord's possession of the security deposit, which may be commingled with
Landlord's own funds. If Tenant defaults in the performance of any of its
obligations hereunder, Landlord may apply any portion of the deposit as
necessary to cure the default or to compensate Landlord for its damages from the
default, and Tenant shall, within Ten days after

                                       2
<PAGE>
 
Landlord's demand therefor, deposit with Landlord the sum that is necessary to
restore the deposit to the full original amount. Upon termination of this Lease,

after curing Tenant's defaults and compensating Landlord for damages caused by
Tenant, shall be returned to Tenant at its last address known to Landlord.

     6.1. Premises. The Premises shall be used only for general industrial, 
          --------

will engage in no activity on the Premises that would, in the judgment of any 
insurer of the Premises, increase the premium on any of Landlord's insurance 
over the amount otherwise charged therefor or cause such insurance to be 
cancelled.  In its use of the Premises, Tenant will comply with all applicable
laws, governmental regulations, and tract restrictions.  Tenant will commit no 
nuisance or waste on the Premises and will not cause any unreasonable odors, 
noise, vibration, electronic emissions, or any other item to emanate from the 
Premises so as to damage Landlord's property or interfere with any other person.
     6.2. Exterior. No portion of the area outside of the Building is leased to
          --------
Tenant. However, Tenant may utilize truck access and turning areas in a
reasonable manner, and Tenant may utilize designated parking areas, in common
with Landlord's other tenants, for daily parking of passenger vehicles.* No
rubbish containers or other materials may be stored outside of the Premises.

from, the exterior of the Premises without Landlord's prior written consent;
such consent will not be unreasonably withheld for any sign that conforms to
sign standards described on an Exhibit to this Lease. Tenant shall have no right
of access to the Building roof, and Tenant shall make no penetrations in the
roof without Landlord's prior written consent. **unless screened and approved
by Landlord.
     6.3. Waste Materials. Tenant shall not discharge commercial or industrial 
          ---------------
wastes into the sewer system serving the Premises.  All such wastes shall be 
disposed of only in sanitary containers that are regularly collected by a 
properly licensed waste disposal firm.  If Tenant causes any waste materials to 
contaminate the Premises or any other property, Tenant shall indemnify Landlord 
and hold it harmless from all claims, demands, liabilities, and expenses, 
including attorneys' fees, arising out of such contamination.
  7. Maintenance and Repair.
     ----------------------
     7.1 Original Condition. If the Premises are complete and vacant when this
         ------------------
Lease is signed, Tenant acknowledges that the Premises are now in good condition
and are not in need of repair. If this Lease is executed while the Premises are
occupied by another tenant or before the Landlord has completed improvements the
Premises that are required by this Lease, then the Premises shall be deemed to
be in good condition and not in need of repair as of the commencement date of
the lease term, excepting only defects that could not be ascertained by 
reasonable inspection, within thirty days the Tenant's negligent use of the
Premises.
     7.2  Landlord's Obligations. Landlord shall maintain, at its expense, the 
          ----------------------
structural soundness of the Building foundation, walls, floors, and roof. 
***Subject to Tenant's obligation to pay a percentage share of the cost in 
accordance with paragraph 8, Landlord shall maintain the exterior of the 
Building and the landscaping, sidewalks, and parking areas (the "Common Area") 
serving the Building. ***except for structural maintainance required and due to 
Tenant's negligent use of the premises.
    7.3  Tenant's Obligations.  Throughout the lease term, Tenant shall 
         --------------------
maintain the Premises, all improvements on the Premises, and all equipment and
systems that service the Premises in good condition and repair. The items to be
repaired by Tenant include, for example and not as a limitation: plumbing,
heating, air conditioning, ventilating, and electrical equipment; walls, floor
slab surface and coverings, ceilings, doors, and glass. Tenant will cause all 
heating, ventilating, air conditioning, and electrical equipment to be 
maintained in accordance with the manufacturers' recommendations and 
specifications, and Tenant will place such equipment under service contract as
required for proper preventative maintenance. At the end of the lease term,
Tenant shall surrender the Premises to Landlord broom clean, in the same
condition as they existed at the commencement of this Lease, together with such
changes as are permitted to remain pursuant to this Lease, excepting only such
ordinary wear as could not have been avoided by routine maintenance.**** If
Tenant fails to perform proper maintenance or repair, including preventative
maintenance where appropriate, Landlord may, after reasonable notice to Tenant
(or without notice for emergency repairs), cause the same to be performed, and
the cost thereof will promptly be paid by Tenant upon receipt of a statement
from Landlord setting forth the amount due.
  8. Costs. Tenant shall pay all utility and maintenance costs, property taxes, 
     -----
and insurance premiums associated with the Premises, as described below.
****This obligation shall not include unrepaired damage that Landlord may be 
obligated to repair under Paragraph 10 of this Lease.

                                      -3-
 

<PAGE>
 
     8.1.  Utility and Maintenance Costs. Tenant shall pay for all costs of 
           -----------------------------
utility services to the Premises, including fire sprinkler monitoring; if 
utilities are not separately metered to the Premises, Tenant shall pay for its 
percentage share.  Tenant shall pay its percentage share of all costs incurred 
by Landlord for the maintenance and repair of the building exterior and Common 
Area during the lease term, including but not limited to painting, parking lot 
surfacing, and roof maintenance (excluding, in the case of roof maintenance, 
expenditures for capital items).
     8.2.  Property Taxes.  Tenant shall pay its percentage share of all taxes, 
           --------------
general and special assessments, and other charges imposed by any taxing
authority and levied against the property containing the Premises or against
Landlord by virtue of its ownership thereof or collection of rental income
therefrom (excepting only estate taxes, inheritance taxes, and income taxes that
are payable on nonrental as well as rental income). "Taxing authority" includes
all entities having taxing or assessment authority by law or by virtue of any
recorded instrument binding on the owner of the Premises.
     8.3. Insurance. Tenant shall pay its percentage share of all premiums for
          ---------
such insurance, as shall be carried by Landlord to insure: the Building, to its
full, against all perils included in the classifications of fire, extended
coverage, vandalism, malicious mischief, special extended perils, and all-risk
sprinkler leakage; against loss of Building rents, property taxes, and insurance
costs for a period of not more than six months; against personal injury and
property damage liability to the extent such insurance is not provided by Tenant
under this Lease; against such other hazards as are then normally insured
against by owners of commercial buildings of the sort containing the Premises.
*replacement cost value excluding the cost of excavations, foundations and
footings
     8.4.  Percentage Share.  Tenant's percentage share of the costs described 
           ----------------
above shall be the percentage stated in the Lease Summary, or, if no percentage
is there stated, shall be determined by the square footage of the Premises
divided by the square footage of the Building. However, if Tenant utilizers more
than its proportionate share of the Common Area, for parking or other purposes,
or more than a normal amount of any utility service, then Landlord may equitably
increase Tenant's percentage share of costs associated with those items to
account for such additional usage. Tenant's percentage share of property taxes
may also be equitably adjusted by Landlord to take a account of any
disproportionate tax burden imposed by special improvements or valuations
relating to other portions of the Building or to other buildings on the tax
parcel, which adjustment may raise or lower Tenant's percentage share; valuation
data contained on the tax assessor's worksheets, if available, shall
conclusively determine the manner in which any equitable adjustment is to be
made. **Tenant shall have the right to review the tax assessor's worksheets as a
method of auditing Landlord's allocations of property taxes to be paid by
Tenant.
     8.5.  Payment.  At Landlord's election, Tenant shall pay its percentage 
           -------
share of such costs to Landlord either (i) when incurred, on the basis on 
Landlord's periodic billings, or (ii) monthly in advance, on the first day of 
each calendar month, and the monthly amount shall be determined by Landlord's 
then-current estimate of the average monthly billing date.  Landlord's initial 
estimate of the average monthly cost may be stated in the Lease Summary.  
Periodically, but not less frequently than annually, Landlord will provide 
Tenant with an accounting of all such costs for the preceding period, and an 
appropriate sum will be credited or debited against Tenant's next monthly rental
payment so as to equalize Tenant's actual payments and Tenant's actual share of
costs for the period. Landlord may revise its monthly cost estimate, and provide
Tenant with an accounting for the previous period, at any time during the lease
term. If the lease term includes only a portion of a taxing or insured period,
then Tenant shall pay a pro rata portion of the total property taxes or
insurance premiums, based upon the number of days in the lease term that are
included in the taxing or insured period; however, Tenant shall pay the entire
amount of any property tax, for the tax year in which this Lease terminates (or
for the succeeding tax year if this Lease terminates after the lien date for
that tax year), levied on or attributable to improvements or property that is to
be removed from the Premises by Tenant prior to or at the end of the lease term.
If the Lease terminates before the property taxes for the then-current fiscal
year are known, the amount of the tax shall be reasonably estimated on the basis
of the best available information on current assessments and tax rates or, if no
such information is available, shall be projected at the same rate as was 
imposed for the last previous taxing period, plus 2%.
  9.  Alterations.
      -----------
      9.1.  Tenant Work. Tenant shall make no alteration, addition, or utility 
            -----------
installation ("Changes") on or to the Premises without Landlord's prior written 
consent.  In making approved Changes, Tenant shall comply with all applicable 
building code requirements.  Unless Landlord has specifically waived this 
provision in writing prior to the installation of Changes, such Changes (i) 
shall be removed from the Premises, and all damage resulting from such removal 
repaired by Tenant, prior to the end of the lease term, or (ii) shall remain on 
the Premises at the end of the lease term and become the property of Landlord, 
at Landlord's election.  If Landlord does not notify Tenant, at least three 
months prior to the end of the lease term, of its election to have Changes 
remain on the Premises, then Landlord shall thereby have elected to require 
Tenant to remove such Changes.  In making all Changes, Tenant shall hold 
Landlord harmless from mechanics' liens and all other liability resulting 
therefrom.
     9.2. Landlord Work and Entry.  Upon execution of this Lease, or at such 
          -----------------------
later time as is feasible and consistent with the terms hereof, Landlord shall 
commence construction of any improvements depicted or described as Landlord work
on an Exhibit or Addendum to this Lease.  Construction of such improvements 
shall be pursued to completion with reasonable diligence, subject to delays for 
reasons beyond Landlord's reasonable control ("Unexpected Events"). Unexpected
Events include, for example, labor difficulties, inclement

                                     -4- 






<PAGE>
 
weather, rationing or other governmental controls, and shortages of materials or
services.  All such improvements shall become part of the Premises and remain 
thereon at the termination of the Lease.  Landlord may enter the Premises at any
time for inspection purposes, and may enter during normal business hours to show
the Premises to prospective tenants in the last 180 days of the lease term.* 
*Provided such entry is consistent with Tenant's security procedures and such 
persons are accompanied by employers of Tenant.
  10. Damage. If any structural portion of the Premises that Landlord is
      ------
obligated to maintain is damaged or destroyed by any cause, if such damage is
insured against, and if the insurance proceeds are available for rebuilding,
then this Lease will not terminate and Landlord will cause such damage to be
repaired with reasonable diligence, subject to delays in the disbursement of
insurance proceeds and Unexpected Events. Landlord's obligation in this regard
shall be enforceable by Tenant only if such damage interferes with Tenant's
reasonable occupancy of the Premises. Tenant's rent will abate to the extent
that the damage and repair period interfere with Tenant's use of the Premises.**
If Landlord elects to repair, rent will abate in the manner described above;
other than the obligation to repair stated above, Landlord shall have no
liability to Tenant on account of the damage.  **See Paragraph 29.0 of Addendum.
  11. Condemnation. If there is a taking by eminent domain or a transfer under 
      ------------
threat thereof of (i) the entire Premises, or (ii) so much of the Premises, for 
the balance of the lease term, as prevents the continued reasonable conduct of 
Tenant's business thereon, then this Lease shall terminate as of the date that 
possession of the condemned premises is delivered to the condemnor.  No other 
such taking or transfer shall terminate this Lease.  All condemnation proceeds 
shall be the property of Landlord, excepting only such portion thereof as is 
designated by the condemnor as compensation for Tenant's moving expenses, loss 
of Tenant's goodwill, or for Tenant's trade fixtures and improvements to the 
Premises actually owned by Tenant.
  12. Liability.
      ---------
     12.1. Insurance. Tenant shall, at its expense, maintain in force during the
           ---------
lease term a combined single limit policy of bodily injury and property damage
insurance, having a liability limit of not less than One Million Dollars
($1,000,000), with contractual liability endorsement, insuring Landlord and
Tenant against all liability arising out of the ownership, use, occupancy, or
maintenance of the Premises and appurtenant areas. Such insurance shall be
endorsed as primary and non-contributing, as to any policy carried by Landlord.
Tenant will deliver to Landlord a certificate evidencing such insurance and
providing that the insurance will not be cancelled except on at least 30 days
notice to Landlord.
     12.2. Indemnity. Tenant shall indemnify Landlord and hold it harmless from 
           ---------
all claims, demands, liabilities, and expenses, including attorney's fees, 
arising out of Tenant's use of the Premises or from any acts permitted by Tenant
on the Premises, excluding claims or actions based upon Landlord's active 
negligence or willful misconduct. Notwithstanding the foregoing, Landlord may 
not obtain any personal or deficiency judgement against tenant or any of 
Tenant's officers, directors, employees or agents.
     12.3. Waiver of Liability (No Subrogation). To the extent allowable by the 
           ------------------------------------
applicable insurance policy without reduction of coverage, Landlord and Tenant 
hereby waive all rights of recovery against the other for loss or damage that is
compensable by insurance then in force or required by this Agreement.
  13. Transfer.
      --------
     13.1. Transfer by Tenant. Tenant shall not assign, sublet, or otherwise 
           ------------------
transfer, or permit a transfer of, all or any portion of its interest in this 
Lease, the Premises, or of a controlling interest in any Tenant entity, without 
Landlord's prior written consent, which shall not be unreasonably withheld. No 
such consent shall relieve Tenant of any liability under this Lease, nor shall
it constitute consent to any further transfer. As a condition of such consent,
the transferee must assume all of Tenant's liabilities hereunder.
     13.2. Transfer by Landlord. The liability of Landlord hereunder shall exist
           --------------------
only with respect to the period that Landlord is the owner of the Premises, but 
all of Landlord's obligations shall run with the land and be binding upon all 
subsequent owners thereof.  Upon any transfer of Landlord's interest in the 
Premises, and notification thereof to Tenant, Landlord shall be relieved of all
liability hereunder except such as may have to Tenant, Landlord shall be
relieved of all liability hereunder except such as may have accrued prior to the
transfer provided transferee agrees to assume Landlord's obligations under this
Lease.
  14. Default.
      -------
     14.1. Events. The occurrence of any of the following events shall 
           ------
constitute a material breach of this Lease and default by Tenant:
        14.1.1. Failure to pay rental within three days after Landlord's 
delivery to Tenant, in the manner described in Section 1162 of the California 
Code of Civil Procedure, or written notice of default;
        14.1.2. Failure by Tenant to perform any nonmonetary obligation under 
this Lease where such failure continues for more than thirty days or,*** if the

the time within which such failure could be cured with reasonable diligence; 
***after receipt of written notice from Landlord
        14.1.3. A general assignment by Tenant for the benefit of creditors; the
filing of a petition by or against Tenant, seeking adjudication or 
reorganization under the Bankruptcy Code; the appointment of a receiver to take 
possession of, or a levy by way of attachment or execution upon, substantially 
all of Tenant's assets at the Premises;
        14.1.4. Tenant falsely stating its financial condition to Landlord, 
either before or after the execution of this Lease.
     14.2 Remedies. After any breach or default by Tenant, Landlord shall have 
          --------
all rights and remedies afforded by law, including but not limited to the 
following:
<PAGE>
 
          14.2.1.  If Tenant's right to possession is expressly terminated in 
writing by Landlord because of such breach, Landlord may recover from Tenant 
such damages as may be allowed under the laws of California, with interest at 
the rate specified in paragraph 17.1, including the worth at the time of the 
award of the amount by which the unpaid rent, for the balance of the term after 
the time of the award, exceeds the amount of such rental loss that the Tenant 
proves could have been reasonably avoided, as discounted to the then present 
value at a rate equal to one percent (1%) over the discount rate of the 
Federal Reserve Bank of San Francisco at the time of the award.

          14.2.2.  Without terminating Tenant's right to possession, Landlord 
may enforce all of its rights and remedies under this Lease, including the right
to recover rent as it becomes due.  For purposes of this provision, any 
reletting of the Premises for a term of less than the unexpired term of this 
Lease or any reletting of a portion of the Premises shall, at Landlord's option,
be deemed to terminate the Tenant's right to possession only with respect to 
such portion of the unexpired term or such portion of the Premises as is the 
subject of such reletting.

          14.2.3.  Landlord may cause a receiver to be appointed to take 
possession of the Premises and all of Tenant's property thereon to protect 
Landlord's interest therein.

     15.  Subordination.  At the option of the holder of any security interest 
          -------------
encumbering the Premises, this Lease shall be either prior to, or subordinate 
to, the lien of such security interest, provided that subordination to a 
security interest created after execution of this Lease shall occur only if the 
security holder agrees* that Tenant's occupancy of the Premises will not be 
disturbed by such security holder, or its successor in interest, so long as 
Tenant is not in default in the performance of its obligations hereunder.
                                                   *in writing
     16.  Tenant Statements.
          -----------------
          16.1.  Offset.  At the request of any prospective purchaser or

execute a written statement certifying that, to the best of Tenant's 
knowledge, (i) this Lease is then unmodified and is in effect, (ii) no rent 
other than that for the current month has been paid in advance, (iii) Landlord 
is not then in default in the performance of any of its obligations, or 
specifying the manner in which any of said matters is untrue.  Tenant's failure 
to execute such written statement within the time required shall constitute an 
admission by Tenant, which may be relied upon by such person, that this Lease is
then in effect without modification, that no advance rent has been paid, and 
that Landlord is not then in default.

          16.2.  Occupancy Certificate.  Upon accepting occupancy of the 
                 ---------------------
Premises, Tenant will, if required by any mortgagee or prospective mortgagee of 
the Premises, complete, execute, and deliver to Landlord a certificate 
reflecting Tenant's acceptance of the Premises, in such reasonable form as may  
be required by the mortgagee.

     17.  General Provisions.
          ------------------

          17.1.  Monetary Payments.  Any monetary payment that is required by 
                 -----------------
this Lease and is not made by Tenant when due shall thereafter bear interest at
the maximum rate as permitted by law. No acceptance by Landlord of any monetary
payment shall constitute a waiver by Landlord of any default by Tenant
hereunder.

          17.2.  Quiet Enjoyment.  So long as Tenant is not in default 
                 ---------------
hereunder, Landlord warrants to Tenant the quite possession of the Premises
throughout the lease term, commencing upon Tenant's actual possession of the
Premises, against all persons lawfully claiming possession thereof.

          17.3.  Construction.  The rent payable under this Lease has been 
                 ------------
determined in light of all other provisions hereof.  Both parties have had equal
opportunity to review this Lease and eliminate any ambiguities contained 
herein, and this Lease shall be fairly interpreted in accordance with its 
reasonable meaning, neither for nor against either party, neither of which is to
be considered as having drafted this Lease.  Captions are for convenience only 
and do not define or limit the provisions of this Lease.

          17.4.  Notices.  Any written notice required to be given to a party 
                 -------
hereunder will be effective upon the earlier of (i) the date that it is 
delivered in the manner required by applicable law, or (ii) three days after 
mailing, if mailed by first class, certified United States mail, posted in 
California, and addressed to the party at its address stated in the Lease 
Summary, or, if no address is there stated, to Tenant at the Premises and to 
Landlord at its then-current address for payment of rent.

          17.5.  Entire Agreement.  This Lease constitutes the entire agreement 
                 ----------------
between the parties concerning the subject matter; neither party has made any 
representations or warranties to the other except as set forth herein.

          17.6.  Attorney's Fees.  In any suit commenced by Landlord or Tenant, 
                 ---------------
the prevailing party shall be entitled to recover its attorney's fees from the 
other.

          17.7.  Time.  Time is of the essence in the performance of all 
                 ----
obligations required by this Lease.

          17.8.  Addendum.  If an Addendum containing additional provisions is 
                 --------
attached to this Lease, the provisions of that Addendum override the provisions 
of the Basic Lease to the extent they are inconsistent herewith.

          17.9.  Counsel.  If a party was represented by counsel in connection
                 -------
with the negotiation and execution of this Lease, that fact is indicated by the

           ----    ---
single lot or parcel, as shown on the last-recorded subdivision or parcel map 
for that property, and located on any portion of the Property; the area of a 
Site or Lot shall be determined by including the area of any portion thereof 
that is subject to an easement and excluding any portion that is part of the 
Public Access Area.

                            IV. Owners' Association
                                -------------------

     4.1   Formation.  Declarant has caused the Association to be incorporated, 
           ---------
under the laws of the State of California, as a nonprofit mutual benefit 
corporation.

     4.2   Purpose.  The purpose of the Association is to serve as an 
           -------
association for the common benefit of the Property and to perform the functions 
set forth herein.

     4.3   Organization.  The Association's membership, officers, and Board 
           ------------
shall be determined in the manner set forth in the Association's Articles of 
Incorporation and Bylaws. In that connection, the Articles of Incorporation 
provide, in part:

           Every person or entity who is the beneficial owner of a Lot, as will
     be defined in the Declaration, (a "Lot") shall be a member of the
     Corporation. Memberships may not be held separately from beneficial
     ownership in a Lot. The transfer of beneficial ownership of a Lot shall
     automatically transfer the membership interest in the Corporation
     associated with such Lot, subject to such conditions and restrictions on
     transfer as may be set forth in the Bylaws of the Corporation. The
     Corporation shall have two classes of membership, as follows:
           Class A. The Class A Member shall be the Declarant, as defined in the
           -------
     Declaration. The Class A Member shall be entitled to a vote, as a Member of
     the Corporation, that is weighted in proportion to four times the acreage
     of the Lots owned by it, according to the recorded map thereof. At such
     time as the Declarant is no longer the owner of any Lot, Class A membership
     shall cease to exist.
           Class B. Class B Members shall be the beneficial owners of all Lots,
           -------
     excluding said Declarant. All beneficial owners of a single Lot shall be
     Members, but all memberships associated with a single Lot shall be entitled
     to a vote, as a Member of the Corporation, that is weighted in proportion
     to the acreage of that Lot, according to the recorded map thereof.

The "Declaration" referred to in said Articles is this instrument.

     4.4   Ownership.  Declarant has conveyed, to the Association, Lot 43, as 
           ---------
shown on the Map, an easement for the portions of the Drainage System that are
located on the Property, and an easement over certain areas now intended for
Landscaping. Declarant may also convey to the Association so much of the
following-described property, or rights therein, as is appropriate for
maintenance by the Association in order to benefit the Property: That portion of
Lot 44, as shown on the Map, on which a levee is to be constructed; the Public
Access

                                      -3-
<PAGE>
 
Area; such other portions of the Property as may be devoted to or developed for 
uses of a public, quasi-public, or common character, including easements for 
landscaped areas, signs, fountains, statuary, or other purposes.

     4.5  Obligations.  The Association shall:
          -----------
          A.  Maintain the Common Area, the Drainage System, the Landscaping, 
and the Public Access Area in good condition and repair, causing any damage to a
Site resulting from such maintenance to be promptly repaired;
          B.  Levy and collect assessments against the Sites in accordance with 
Article VIII;
          C.  Enforce the restrictions created hereby, and pursue the remedies 
allowed by Article VIII, to the extent the Association deems it advisable to do 
so;
          D.  Allow each Owner to drain surface water from his Site into the 
Drainage system, subject to the approvals required by Article V;
          E.  Pay, before delinquency, all taxes and assessments levied on the 
Common Area;
          F.  As required by the City of Fremont in connection with its approval
of the Map, cooperate with the following persons of entities for the purposes 
indicated:
              (i)   Other property owners in the vicinity of the Property, in 
establishing an emergency medical facility;
              (ii)  Public transportation agencies, to encourage the use of 
public transportation by those persons employed on the Property;
              (iii) The Fremont Fire Department, in establishing a hazardous 
materials handling program;
              (iv)  The Fremont Police Department, on security measures;
              (v)   The Union Sanitary District and Water Quality District, to 
encourage waste water recirculation processes for large waste water generators;
              (vi)  Local recyclers for regular pickup of materials;
              (vii) Public and private agencies to encourage industrial users to

          G.  Obtain such insurance as may be appropriate;
          H.  Perform such other acts, whether or not expressly authorized by 
this Declaration, as may be reasonably necessary for the furtherance of its 
purposes, duties, rights, and powers, as set forth herein or in the Articles or 
Bylaws of the Association.

     4.6  Delegation of Duties to Owner.  The Association may, if reasonably 
          -----------------------------
required by the landscaping character or configuration, require an Owner, by 
written notice, to maintain all landscaping bordering upon the Owner's Site 
which lies within the property that has been dedicated to the City of Fremont.  
In such event, the Owner shall receive a credit, against the Owner's share of 
assessments made pursuant to Section 8.1, for the maintenance cost saved by the 
Association because of the Owner's landscaping maintenance. The Association may
also at any time, by written notice to the Owner, revoke a prior delegation of
maintenance duties made under this Section.
       
                                      -4-

<PAGE>
 
     4.7.  Maintenance District. At any time that the Association determines 
           --------------------- 
it to be feasible, the Association may assign any of its rights or obligations
to a maintenance district formed as a public agency under the laws of
California. Each Owner shall join in the formation of such maintenance district,
as and when requested by the Association, as necessary to allow the district to
levy assessments against the Property so that it may perform the Association's
prior obligations.

     4.8.  Destruction of Improvements. If there is a partial or total
           ----------------------------
destruction of any Improvements owned or maintained by the Association, the
Association shall restore and repair the same to their former condition, as
promptly as is reasonably practicable, in a workmanlike manner. If the cost of
restoration or repair exceeds the amount of any available insurance proceeds,
the Association may levy a special assessment on the Property for the excess
cost of restoration or repair. If any excess insurance proceeds remain after
completion of any restoration and repair, the Association shall retain such sums
in its general funds.

     4.9.  Condemnation of Association Property. If there is an actual or
           -------------------------------------   
threatened taking by power of eminent domain of all or any portion of the
property or Improvements owned or maintained by the Association, the Board shall
represent the Association and all of the Owners in connection with the taking.
The Board may act, in its sole discretion, with respect to any settlement made
in connection with any such taking, and shall be entitled to make a voluntary
sale, at any price acceptable to the Board, to the condemnor in lieu of
condemnation. Any condemnation award or sale proceeds received on account of
such a taking shall be paid to the Association. If there is a taking of less
than all of the property owned and maintained by the Association, and
if restoration and repair of the remainder is required for the benefit of the
Property and is practical, the Association shall apply the proceeds of the
taking to the restoration and repair and may levy a special assessment on the
Property for any excess cost thereof. If such restoration and repair is not
practical, or if there is a taking of all property owned and maintained by the
Association, then the Association shall distribute the amount of any
condemnation award or sale proceeds that remains, after discharging all of the
Association's obligations, to the members of the Association, pro rata, based on
the acreages of their respective Sites.

                                V. Improvements
                                ---------------

     5.1.  Approval. No Improvements, excepting those that do not materially 
           --------- 
alter existing Improvements, shall be erected, placed, altered, maintained or 
permitted to remain on any Site by any Owner or occupant until final plans and 
specifications for such Improvements have been approved by the Agent. The 
Agent's approval may be conditional, in that it may require that certain 
designated changes be made. The plans and specifications shall be prepared or 
approved in writing by a licensed architect and shall be submitted to the Agent,
by the Owner of the Site or his designated representative, in duplicate. 
Material changes in approved plans must also be submitted to and approved by the
Agent. All plans and specifications submitted shall be in

governmental authority for the issuance of a building permit.

     5.2.  Basis for Approval.  The Agent's approval shall be based, among other
           ------------------
things, upon adequacy of lot dimensions, adequacy of structural design,
conformity and harmony of external design with neighboring structures, effect of
location and use of proposed Improvements upon neighboring Sites, proper facing
of main elevation with respect to nearby streets, adequacy of screening of
mechanical, air conditioning or other rooftop installations, and conformity of
the plans and specifications to the purpose and general plans and intent of this
Declaration. Plans and specifications must provide for the underground
installation of power, electrical, telephone and other utility lines from the
property line to buildings. The Agent shall not arbitrarily or unreasonably
disapprove any plans or specifications; disapproval shall be in writing and
shall describe, with reasonable specificity, the reasons therefor. The Agent may
disapprove plans or specifications on any reasonable ground including, but not
limited to, the following:

           A.  Failure to comply with any of the restrictions set forth in this
Declaration;

           B.  Failure to include such information in the plans and

render the proposed Improvements or use inharmonious with the general plan for 
improvement of the Property or with Improvements located upon other Sites 
or other property in the vicinity.

     5.3.  Plan Review.  A review fee of two hundred fifty dollars ($250) shall 
           -----------
be paid to the Agent at such time as plans and specifications are submitted to 
it. All plans, specifications, and changes thereto that are submitted to the 
Agent shall be deemed approved thirty (30) days after the date on which such 
items are submitted to the Agent, unless the Agent has theretofore disapproved 
such items by written

                                      -6-

<PAGE>
 
notice to the Owner or the Owner's designated representative. A copy of all

            -----------------------------------
commence and complete all Improvements for which final plans and specifications 
have been approved by the Agent. If work does not commence within one (1) year 
from the date of approval of the final plans and specifications, or if the 
improvements are not completed within two (2) years from such date, approval 
shall thereupon be automatically revoked unless the Agent extends, in writing, 
the period of time within which work must be commenced or completed. If work 
upon the Improvements is delayed by strike, fire, national emergency, natural 
disaster or other supervening force beyond the reasonable control of the Owner
or occupant, the period of time within which work must be commenced and
completed shall be extended by the same period as the delay.

      5.5.  LIABILITY.  Neither the Agent nor the Association shall be liable 
            ---------
for any damage, loss or prejudice suffered or claimed by any person on account 
of its approval or disapproval of any plans, drawings or specifications, the 
development of any Site, the construction of any improvement or the performance 
of any work, whether or not pursuant to approved plans, drawings and 
specifications. The Agent's approval or disapproval of any plans, drawings and 
specifications shall not be deemed a representation as to whether the proposed 
Improvements comply with the applicable laws or whether they may in any way be 
defective.

      5.6.  WAIVER.  The Agent may, in good faith, waive or vary the 
            ------
requirements of this Article V as it deems appropriate in order to fulfill the 
purposes of this Declaration. Such waiver or variance shall not constitute a 
waiver or variance as to any other Site.

      5.7.  NO AGENT.  If at any time, no person or entity is serving as the 
            --------
Agent, the Improvements may be constructed in accordance with any plans and 
specifications that satisfy the requirements of the City of Fremont, or other 
public agency having jurisdiction over the Property, for issuance of a building 
permit.

            -------------
level of all buildings on any Site shall not occupy more than forty percent

         -------------
accommodate the parking needs of all businesses conducted on that Site,
including employees and visitors, consisting of not fewer than three (3)
parking stalls for each 1,000 square feet of building floor area. The Agent may
require a greater parking ratio if the proposed use of the Site so necessitates

<PAGE>
 
any on-street parking.  If parking requirements for a Site increase as a result

property upon which the parking area is located, reserving that property for
such parking use.

painted upon the paved surface and shall be adequately sized.  All parking areas
shall provide, in addition to parking spaces, adequate driveways and space for 
the movement of vehicles and shall comply with applicable laws.
          C.  In determining the adequacy of the number of parking spaces to be 
provided, the Agent shall consider the nature of the proposed use of the Site, 
the amount of vehicular traffic generated by such use, the anticipated number of
employees and the manner of their employment, the nature and location of
proposed structures on the Site and such other matters as the Agent considers
relevant.
          D.  No parking spaces shall be located on or permitted closer than 
twenty-five (25) feet to the curb line of an adjacent street without the Agent's
written consent.

           B. Cleaning, maintaining, and relamping of all external lighting
fixtures;
           C.  Maintaining all landscaping, including trimming, watering and 
fertilization of all grass, ground cover, shrubs or trees, removal of dead or 
waste materials, and replacement of any dead or diseased grass, ground cover, 
shrubs or trees.
           D.  Keeping all outdoor refuse collection containers covered and 
visually screened so as not to be visible from neighboring Sites or streets.
 
     7.7. Hazardous Substances.  All hazardous substances on a Site shall be 
          --------------------
stored and disposed of only in accordance with the requirements of state and 
federal law.  The Association or its agents may, without having any obligation 
to do so, enter on a Site at all reasonable times for the purpose inspecting for
the existence of hazardous substances and determining whether they are being 
stored and disposed of properly. The Association shall be entitled to bring an
action, in state or federal court, (i) to enjoin the violation on the Property
of any state of federal law dealing with hazardous substances, and (ii) to 
recover

                                     -11-
<PAGE>
 
damages, including attorney's fees, on its own behalf and on behalf of all 
Owners from any person violating such a law on the property.

      7.8.  Solar Access.  No Owner shall unreasonably interfere with another 
            ------------
Owner's access to solar energy, and each Owner shall, as and when requested by 
the Owner of a contiguous Site, make available such solar access easement as may
be reasonably required by such other Owner. Any Owner providing such a solar 
access easement may charge a reasonable price therefor. It is not the intent of 
this Section 7.8 to preclude any Owner from making reasonable use of his Site, 
nor is it intended that any Owner's construction of solar energy collectors will
thereby create a solar access easement across another Owner's Site without 
reasonable payment being made therefor. No solar access easement shall exist on
any portion of the Property, so as to be binding upon a bona fide purchaser or 
encumbrancer, unless it is evidenced by a written instrument that is duly 
recorded in the Official Records of the County in which that portion of the 
Property is located.

      7.9.  Compliance Certificate.  Any Owner or bona fide, prospective 
            ----------------------
purchaser or encumbrancer of a Site, for value, may, by written request, obtain 
from the Association a written statement to the effect that the Site then 
complies in all respects with the requirements of Articles V, VI, and VII of 
this Declaration, or setting forth in reasonable detail the manner in which the 
Site does not so comply. If the Association fails to supply such a statement 
within fourteen (14) days of its receipt of the written request therefor, then 
it shall be conclusively deemed that the Site then complies in all respects with
those requirements.

                        VIII.  Assessments and Remedies
                               ------------------------

      8.1.  Right to Assess.  The Association, by action of the Board, shall 
            ---------------
assess the Property and the Owners, as necessary to provide funds to perform all
obligations of the Association, according to the terms of this Declaration. Such
assessments shall be made against all Sites, in proportion to the respective 
acreages thereof, according to the following procedure:

           A.  The Association shall operate on a fiscal year ending June 30. 
Annually, on or before September 1 of each fiscal year, the Board shall provide 
each Owner, by notice, with a proposed Association budget for that year and a 
notice of annual assessment, setting forth that Owner's assessed share of the 
funds that the Board estimates will be required by the Association to meet its 
budgetary requirements. Assessments, as set forth in the notice, shall be due 
and payable in two equal installments, on December 10 and April 10.

           B.  If at any time the Association requires additional funds, because
of unbudgeted requirements, failure to collect annual assessments, or any other 
reason, the Board may, by notice to each Owner, levy a special assessment, which
will be due and payable to the Association fifteen (15) days after the date the 
notice is given.

           C.  Within ninety (90) days after the end of each fiscal year of the 
Association, the Board shall provide each Owner with a written financial 
statement, showing the Association's receipts and expenditures during the 
preceding year, in reasonable detail, and a balance sheet

                                     -12-

<PAGE>
 
setting forth the assets and liabilities of the Association as of the end of the
preceding year.  Such financial statement shall be prepared by an independent 
certified public accountant, but need not be audited.

     8.2. Remedies of the Association.  Any assessment levied against a Site 
          ---------------------------
which is not paid when due shall become delinquent.  The Board may, at its 
option, require that any delinquent assessment bear interest, from its original 
due date, at the then-maximum legal rate or one and one-half percent (1 1/2) 
per month, whichever is greater, and a late charge of six percent (6%) of the
amount of the unpaid assessment. The Association may, in addition to any other
remedy the Association may have, collect a delinquent assessment as follows:

          A. The Association may bring suit against the Owner, who shall be 
personally obligated to pay the assessment.  The prevailing party in any such 
action shall be entitled to recover its reasonable attorneys' fees.

          B. The Board may deliver a notice to the defaulting Owner, which 
notice shall state the date of the delinquency, the amount of the delinquency, 
including interest and any late charge, and make demand for payment thereof.  If
such delinquency is not cured within ten (10) days after delivery of such 
notice, the Association may record in the Office of the Recorder of Alameda 
County a claim of lien against the Site of the delinquent Owner.  The claim of 
lien shall state: (i) the name of the delinquent Owner or reputed Owner; (ii) a 
description of the Site on which the claim is made; (iii) the amount claimed to 
be due and owing; (iv) that the claim of lien is made by the Association 
pursuant to the terms of this Declaration; (v) that a lien is claimed against 
said Site in an amount equal to the amount of the delinquency including 
interest, any late charge, costs, and attorneys' fees; (vi) a date, not less 
than thirty (30) days from the date the claim is recorded, by which the 
delinquency must be cured. Any such claim of lien shall be signed and
acknowledged by an authorized officer of the Association and shall create a lien
against the Site upon the recordation thereof. Each default shall constitute a
separate basis for a claim of lien. The lien created by the claim of lien may be
foreclosed in the manner provided by law for either (i) judicial foreclosure of
a mortgage or (ii) foreclosure of a mortgage by power of sale and, for that
latter purpose, the Association is hereby granted a power of sale with respect
to each Site. If foreclosure is by suit, the Association may also recover its
reasonable attorney's fees. If foreclosure is by power of sale, the Board or a
person designated by it in writing shall conduct the sale and shall be entitled
to actual expenses and such fees as may be allowed by law or as may be
prevailing at the time the sale is conducted in accordance with the provisions
of the California Civil Code, Sections 2924 and following, or in any other
manner permitted by law. A certificate of sale shall be executed and
acknowledged by any authorized officer of the Association or by the person
conducting the sale. Such a certificate executed, acknowledged and made under
penalty of perjury by any two authorized officers of the Association shall be
conclusive upon the Board, the Association, and all Owners, in favor of any and
all persons who rely thereon in good faith as to the matters contained therein.
If the Association fails to collect the full amount of the delinquent assessment
at such sale, it shall continue to have the right to enforce, by suit, the
personal liability of the Owner therefor. If any

<PAGE>
 
claim of lien has been recorded as herein provided, and thereafter the 
Association receives payment in full of the amount claimed to be due and owing 
together with all accrued interest, late charges, costs, and attorney's fees 
incurred by the Association, then, upon demand by the Owner, the Board, acting 
through any authorized officer of the Association, shall execute, acknowledge 
and record a release of the Association's claim of lien.

          C.  The remedies of the Association hereunder shall be in addition to 
and shall not exclude any other rights and remedies which the Association may 
have by law.

     8.3.  Mortgagee Protection.  The Association's foreclosure of a lien for 
           --------------------
delinquent assessments shall not extinguish or render invalid the lien of any 
mortgage or deed of trust encumbering a Site, provided that the mortgage or deed
of trust secures a bona fide debt, created for value.  However, any person 
acquiring a Site upon foreclosure of such a mortgage or deed of trust, or by 
deed in lieu thereof, shall acquire the Site subject to the obligation to pay 
all delinquent assessments, including those that may still be unpaid after the 
Association's foreclosure of its lien.

     8.4.  Assessment Statement.  Any bona fide, prospective purchaser or 
           --------------------
encumbrancer of a Site for value may, by written request accompanied by a fee of
twenty-five dollars ($25), obtain from the Association a written statement 
setting forth the amount of any regular, special or individual assessment 
against such Site which is either delinquent or assessed but not yet due and 
payable (an "Assessment Statement").  If the Association fails to supply an 
Assessment Statement within fifteen (15) business days of its receipt of such 
written request and fee, then it shall be conclusively deemed that there are no 
outstanding assessments against such Site as of the date of such written request
unless a claim of lien has theretofore been recorded against the Site in 
accordance with Section 8.2 hereof.

     8.5.  Other Violations.  If any violation of a covenant, condition, or 
           ----------------
restriction contained herein comes to the attention of the Board, the Board may
deliver a notice of violation, in writing, to the Owner of the affected Site. If
the violation described in the notice is not corrected within thirty (30) days
after the date such notice is given, the Association may, if such violation may
be corrected without entering into any building on the Site, then enter on the
Site and correct the violation at the Owner's expense, and the Owner will
reimburse the Association for the cost thereof, plus an administrative charge of
fifteen percent (15%) of that cost, on demand. The Association is hereby granted
a license to enter on all Sites as necessary to correct such violations. Whether
or not violations may be corrected by entry onto a Site, and whether or not a
notice of violation has theretofore been given, the Association may bring suit
against an Owner to enjoin a violation, to recover any damages to Association
property resulting therefrom, and to pursue any other remedy allowed by law; in
any such action brought by the Association, the prevailing party shall be
entitled to recover its reasonable attorney's fees.

     8.6. Sewer Lift Station Assessments.  The Owners of Lots 17 through 34, as
          ------------------------------  
shown on the Map, are hereby notified that a sanitary sewer lift station has 
been constructed to serve those Lots and certain other property not now part of 
the Property. The lift station will be maintained by the Union Sanitary District
(the "District") under an arrangement by which all costs of maintaining,
operating, and replacing the lift station will be charged to the owners of the
properties then being served by the lift station, with such costs apportioned
among those properties in such reasonable manner as may be determined by the
District. Such costs may include, but are not limited to, the costs of the
District's labor, power, and an equipment replacement allowance determined by
amortizing the replacement costs of the equipment's useful life. The apportioned
costs may be collected directly by the District, by assessment, or, at the
District's option, may appear as additional charges on annual property tax bills
issued by the County Tax Collector. To enable the District to enforce its
assessments, the District is hereby granted a lien against Lots 17 through 34.
If an assessment against any of said Lots is not paid when due, the District may
foreclose its lien against such Lot in the manner provided by California law for
judicial foreclosure of a mortgage or deed of trust.

                               IX. Annexations
                                   -----------

     9.1. Annexations to the Property.  If Declarant then owns at least ten 
          ---------------------------
percent (10%) of the Property, by area, real property other than the Property
may become subject to this Declaration by means of annexation. Such other real
property must (i) be contiguous to the Property, and (ii) not cause a material
increase in the financial obligations of the Owners, by reason of a
disproportionately large common area or otherwise. Other real property shall be
considered "contiguous" if it is separated from the Property only be real
property owned by a public agency. Annexation shall be accomplished by
Declarant's filing for recordation, in the office of the County Recorder where
the real property to be annexed is located, an executed Notice of Annexation
describing the other real property, referring to this Declaration, and stating
the other real property is thereafter to be included in the Property for
purposes hereof.

     9.2. Effect of Annexation.  With respect to any real property annexed 
          --------------------
pursuant to this Article IX:

          A.  Each Owner of a portion of such real property, but virtue of being
such an Owner and for so long as he is such an Owner, shall enjoy all the rights
and have all the obligations of any Owner hereunder and shall be a member of the
Association.

          B.  The terms "Owner", "Lot", "Property", and "Site" shall refer to 
such annexed real property or portions thereof, or its owner(s), as the context 
may require for the proper inclusion of such other real property in the scheme 
of this Declaration.

          C.  The Notice of Annexation may contain such other covenants, 
conditions, and restrictions, applicable to the annexed real property, including
provisions that differ from provisions of this Declaration, as Declarant deems 
appropriate.

                      X. Covenants Running With the Land
                         -------------------------------

     10.1. Covenants.  The covenants, conditions, and restrictions set forth 
           ---------
herein are made by Declarant on its own behalf, as owner of the Property, and on
behalf of the successive owners of all Sites, for the direct benefit of the
entire Property and shall be "covenants" that "run with the land", as referred
to in Section 1468 of the California Civil Code. The burdens created by this
Declaration shall be binding upon each Site and the successive owners thereof.
Each Owner of a Site shall acquire the Site subject to the prior Owner's
obligation to pay any unpaid assessment, and any other amounts due hereunder,
assessed against or payable with respect to such Site or the prior Owner's
actions. Accordingly, Declarant, on its own behalf and on behalf of the
successive owners of Sites, specifically waives the provisions of California
Civil Code Section 1466, which provides:

     No one, merely by reason of having acquired an estate subject to a covenant
     running with the land, is liable for a breach of the covenant before he
     acquired the estate, or after he has parted with it or ceased to enjoy its
     benefits.

The provisions of this Section 10.1 shall not limit any claim or right an Owner 
of a Site may have against his predecessor in interest for failure to pay 
assessments or for other obligations incurred prior to the date such Owner 
acquired title to the Site.

     10.2 Right to Enforce.  No Owner shall have the right to bring suit against
          ----------------
another Owner or any other person to enforce the obligations of such other Owner
or person under this Declaration, it being the intent of this Declaration that, 
except as may otherwise be specifically provided herein, only the Association 
shall have the power, right and authority to enforce the provisions of this 
Declaration against the Owners.


                            XI. General Provisions.
                                ------------------

     11.1. Expiration and Amendment. The provisions of Articles V and VI of this
           ------------------------
Declaration, excepting Section 6.9, shall automatically expire and have no
further effect as of December 31, 2009; provided that, at any time during the
year 2009, Owners of Sites constituting not less than two-thirds (2/3) of the
Property, by area, may extend said provisions for a designated additional term
that does not extend beyond December 31, 2019. The remaining provisions of this
Declaration shall run with and bind the Property in perpetuity. This Declaration
may at any time be amended by the vote of Owners holding not less than two-
thirds (2/3) of the voting power of the Association. However, so long as
Declarant owns at least ten percent (10%) of the Property, by area, or for a
period of fifteen (15) years from the date of recordation of this Declaration,
whichever is longer: (i) no amendment hereof shall be effective without the
written approval of Declarant, and (ii) Declarant may amend this Declaration
without the consent of any other party, but only with respect to procedural or
technical matters that further the apparent original purpose hereof and do not
alter the respective rights and obligations of the Owners. The written

                                     -16-
<PAGE>
 
consent of the City of Fremont, California, shall be required for any amendment 
to this Declaration that purports to alter the effectiveness of any of the 
following Sections of this Declaration: 4.5(F), 6.9, 7.3 or 11.1 (this sentence 
only).  To be effective, an amendment to this Declaration must be in writing, 
executed by the required party or parties, and filed for recordation in the 
Office of the Recorder of the County or Counties where the Property is located; 
no amendment will be effective against an Owner who acquired a Site prior to the
recordation of the amendment, until the Owner has actual knowledge of the 
amendment.

     11.2. Notices.  Any notice required or desired to be given or sent pursuant
           -------
to or with respect to this Declaration shall be in writing and shall be 
personally served, or, in lieu of personal service, may be given by depositing 
such notice in the United States mail, certified or registered, postage 
prepaid, addressed to the party to be served at its address as shown in the 
records of the Alameda County, California, Tax Assessor.  Any notice given by 
certified or registered mail shall be deemed to have been given on the third 
business day after its deposit in the United States mail.  Any Owner or the 
Association may, by written notice to the Association or, in the case of the 
Association, to all Owners change the address to which notices addressed to it 
shall thereafter be mailed.  Until changed, the address of the Association and 
the Agent shall be c/o King & Lyons, 3000 Sand Hill Road, Building 4, Suite 245,
Menlo Park, California  94025.  If a Site is owned by more than one Owner, then 
such co-Owners shall designate, by written notice to the Association, a single 
Owner as their agent to receive notices hereunder, and any notice given to such 
designated Owner shall be deemed given to all the Owners of such Site.  In the 
absence of any such designation, any notice given to any one of the co-Owners of
a Site shall suffice as notice to all co-Owners.

     11.3. Interpretation.  The provisions of this Declaration shall be fairly 
           --------------
construed so as to effectuate their purpose of creating and implementing a 
continuing uniform plan to facilitate the Association's performance of its 
obligations, assessment of the Owners for the costs and expenses paid or 
incurred by the Association, the creation and enforcement of liens to secure 
payment of such assessments, and the development of the Property as a business 
park of uniform quality and appearance.  If any provison of this Declaration is,
or is adjudged to be, unenforceable or invalid, the remainder shall continue in 
full force and effect.  The heading contained in this Declaration are for the 
purpose of reference only, and are not an aid in the construction or 
interpretation of any provision hereof.

     IN WITNESS WHEREOF, Declarant has executed this Declaration on the date 
first above written.

                                       Declarant:

Interlink and its End Users from any claim, liability, damage or expense
including but not limited to legal expenses of whatever kind for, or on account

(including attorneys' fees) from Legato and shall further have the right to

constitute an infringement or misappropriation.

     Legato will not be liable under this Section 10 if the Software or
Documentation has been modified by any of the parties indemnified hereunder and
such modification is solely the cause of any such infringement or
misappropriation unless such modifications were made in accordance with Legato's
instructions.

or indirectly either for itself, or with or for any other person or corporation
in any work or undertaking which shall conflict with or create any legal
impediment against Legato's performance or obligations under this Agreement and
the rights and licenses granted to Interlink hereunder. Legato represents that
there is no such present conflict of interest nor any such legal impediment.

     14.9  Counterparts. This Agreement may be executed in any number of

Interlink's possession, all risk of loss shall be Legato's.

     14.12  Personal Injury/Property Damage. Each party (the "Indemnifying
            -------------------------------                                
Party") shall hold harmless the other party from any claim by a Third Party of

3145 Porter Drive, Palo Alto, California 94306.

     1.   Appointment. Subject to the terms and conditions of this Agreement,

Seller hereby appoints Agent and Agent's authorized representatives as Seller's
sales representative for Seller's products listed in Seller's published price
list (the "Products") to end user customers ("End Users") worldwide.

     2.   Validity of Terms and Conditions. The terms and conditions of this
          --------------------------------                                  
Agreement shall remain valid until otherwise superseded or changed by mutual
agreement of Seller and Agent.

     3.   Product Ordering Process. To order Product(s), Agent shall secure a
          ------------------------                                           
purchase order from an End User which must contain, at a minimum, the following
information: (i) identification of Product(s) by quantity, Product number from
Seller's published price list, description and charge, and (ii) shipment
instructions including destination, method of shipment (UPS-Ground is standard)
and requested delivery dates. Terms and conditions on such purchase order shall
not modify this Agreement unless agreed to in writing by Seller.

     4.   Promotional Materials. Seller shall furnish Agent with reasonable
          ---------------------                                            
quantities of samples, catalogues, literature, demo and trial copies of the
Products and any other materials Seller deems necessary for proper promotions
and sales presentations of its Products at no charge.

     5.   Trademarks. During the term of this Agreement, Agent shall have the
          ----------                                                         
right to indicate to the public that it is an authorized representative of
Seller's Products and to advertise such Products under the trademarks, marks,
and trade names of Seller that Seller may adopt from time to time ("Seller's
Trademarks") and in the promotion of the Products; provided, however, that upon
thirty (30) days prior written notice to Agent, Seller may substitute
alternative marks for any or all of the Seller's Trademarks. All representations

Seller for approval (which shall not be unreasonably withheld) of design, color
and other details or shall be exact copies of those used by Seller.

Agreement shall be a commission computed in accordance with this Section 7. The
commission shall apply to all purchase orders for Products solicited by Agent
that have been accepted by Seller and for which shipment has occurred. Agent
shall receive a commission on such sales of Product(s) which is equal to the
amount derived from the following formula: Commission = invoiced price to End
User for Product - [*]% of Legato list price for Product as of date of order. In

                          PLAN OF BUSINESS ACQUISITION
                          ----------------------------

     2.1  The Offer.
                                       --------- 

          (a)  Provided that this Agreement shall not have been terminated
pursuant to Section 12 and that the conditions set forth in Section 11 of this
Agreement shall have occurred, Interlink shall, as soon as practicable after the
date hereof commence an offer for all of the outstanding New Era Common and all
of the outstanding New Era Options for the consideration set forth in Section
2.3.

          (b)  The obligations of Interlink to accept for payment and pay for
any of the New Era Common or New Era Options tendered shall be subject only to
the Closing conditions set forth in Section 11 of this Agreement, including the
condition that ninety-eight percent (98%) of the New Era Common outstanding on a
fully diluted basis (including for purposes of such calculation all shares
issuable upon exercise of outstanding New Era Options and any other rights or
securities to purchase or acquire any capital stock of New Era), being validly
tendered and not withdrawn prior to the expiration of the Offer (the "Purchase
Condition"). The Offer shall remain open until December 28, 1995 (the
"Expiration Date"), unless Interlink extends the Offer as permitted by this
Agreement, in which case the "Expiration Date" means the latest time and date to
which the Offer is extended.

          (c)  Interlink reserves the right to waive any conditions to the Offer
to increase the price per share payable in the Offer or to make any other
changes in the terms and conditions of the Offer; provided, however, that no
such change may be made which decreases the price per share, changes the form of
consideration payable in the Offer, imposes conditions to the Offer in addition
to those set forth in Section 11 of this Agreement or amends any other material
term of the Offer in a manner materially adverse to those tendering their shares
without New Era's prior written consent.  If all conditions set forth in Section
11 of this Agreement are satisfied on the initial Expiration Date, other than
the Purchase Condition, Interlink may extend (and re-extend) the Offer until the
termination of this Agreement to provide time to satisfy such conditions, so
long as all such other conditions remain satisfied.

          (d)  The Offer shall be made by means of an Offer to Purchase
containing the terms set forth in this Agreement and certain other terms
applicable to the manner of delivery of the certificates representing the
outstanding shares and the documents representing the New Era Options, and the
manner of payment to be made upon receipt of the certificates and documents.

     2.2  Contingent Acquisition Activities.  Should the Purchase Condition
          ---------------------------------                                
not be met and should Interlink determine that sufficient shareholders and
optionees have tendered for Interlink to waive the Purchase Condition pursuant
to Section 2.1(c), then Interlink may, at such time after the Closing as it sees
fit, undertake such actions as it believes are required to acquire ninety-eight
percent (98%) of all outstanding new Era Common, all outstanding New Era
Options, and any other rights or securities to purchase or acquire any capital
stock of New Era.  Such actions may include (a) accepting tenders of New Era
Common, or New Era Options after the Closing Date, (b) compulsory acquisition of
any remaining shares as permitted by Alberta Law if the Offer to Purchase has
been accepted by the holders of not less than ninety percent (90%) of the New
Era Common, or (c) an amalgamation, statutory arrangement or other transaction
involving Interlink or an affiliate of Interlink pursuant to which a special
meeting of the shareholders of New Era may be called, provided, however, that
any such actions will only be undertaken on the same terms as are offered under
Section 2.1, New Era and the Principal Shareholders agree to undertake their
reasonable commercial efforts to assist Interlink with any such procedure.

     2.3  Consideration for Outstanding Securities.  Shareholders and
          ----------------------------------------                   
Optionholders wishing to accept the Offer to Purchase will deposit their share
certificates or option documents, respectively, together with a letter of
transmittal and any other required documents to the Depository prior to the
Expiration Date.  At the Closing, Interlink will deliver to the Depositary for
the benefit of the tendering Shareholders and Optionholders the Closing
consideration as follows:

          (a)  The Initial Payment Note.   Interlink will issue a promissory 
               ------------------------
note due January 4, 1996 in the form attached to this Agreement as Exhibit B
(the "Initial Payment Note"). The Initial Payment Note will be a single note for
the benefit of all tendering Shareholders and Optionholders which such holders
shall own beneficially in the following proportions:

               (i)  New Era Common.  The tendering holders of New Era Common
                    --------------    
shall be entitled to receive out of the Initial Payment Note an amount equal to
the principal on the Initial Payment Note divided by the total number of shares
of New Era Common and Class A Common Stock issuable upon exercise of New Era
Options, and multiplied by the number of shares of New Era Common held by such
holder.

               (ii) New Era Options.  The tendering holders of New Era Options
                    ---------------   
shall be entitled to receive out of the Initial Payment Note an amount equal to:
(A) the principal on the Initial Payment Note divided by the total number of New
Era Common and common stock issuable upon exercise of New Era Options, minus (B)
$15.00, then multiplied by (C) the number of shares of common stock of New Era
issuable upon exercise of such New Era Option.

          The Depository will be instructed to make payment to the tendering
Shareholders and Optionholders on January 4, 1996 of the amounts due under the
Initial Payment Note from amounts deposited by Interlink with the Depository at
Closing, provided, however, that the Depository will be instructed to pay to New
Era out of each Shareholder payment any amounts of principal and accrued
interest on any obligations to New Era incurred for the purchase of such shares
outstanding at Closing.

          The principal amount of the Initial Payment Note shall equal CDN
$15,000,000, minus $384,000 to be paid at the Closing by Interlink to Concord
Corporation as part of the Fees, minus an aggregate of $150,000 for the
estimated fees of the Depository, Ernst & Young as accountants for New Era, and
MacLeod Dixon as counsel to New Era, which will be paid when due by Interlink,
minus the amount paid by New Era prior to the Closing in redemption of 50,000
shares of New Era Class A Preferred Stock outstanding as of the date of this
Agreement (the remaining 20,000 shares of New Era Class A Preferred Stock are
also to be redeemed prior to Closing in exchange for an outstanding note payable
to New Era), minus the amount paid by New Era prior to the Closing in redemption
of 30,000 shares of New Era Class B Preferred Stock outstanding of the date of
this Agreement, and plus the aggregate exercise price of all New Era Options
outstanding as of the Closing.

          (b)  The Deferred Payment Notes.  Interlink will issue promissory 
               --------------------------    
notes in the aggregate principal amount of CDN $9,000,000, with CDN $2,000,000
due on January 2, 1997, CDN$3,500,000 due on January 31, 1997, and the remaining
CDN $3,500,000 due on January 31, 1998, in the form attached hereto as Exhibit C
(the "Deferred Payment Notes"). A Deferred Payment Note will be issued at the
Closing to (i) each tendering holder of New Era Common and New Era Options and
(ii) Concord Corporation in the amount of $360,000 as part of the Fees, and will
be delivered to the Depository for distribution to such holders and Concord
Corporation, respectively, on January 4, 1996. Each tendering holder of New Era
Common and New Era Options shall be entitled to receive a Deferred Payment Note
in principal amount equal to CDN $8,640,000 divided by the total number of
shares of New Era Common 

                                      -5-
<PAGE>
 
and common issuable upon exercise of New Era Options, multiplied by the number
of shares of New Era Common and/or common issuable upon exercise of New Era
Options held by such Shareholder or Optionholder.

          (c)  Warrants.  Interlink will issue at the Closing a Warrant in the
               --------                                                       
form attached hereto as Exhibit A to each tendering holder of New Era Common or
New Era Options exercisable under its terms for a number of shares of Interlink
Common Stock equal to (1) 700,000 minus 28,000 shares underlying the Warrant
granted to Concord Corporation at the Closing as part of the Fees, divided by
(2) the total number of shares of New Era Common and common issuable upon
exercise of New Era Options, multiplied by (3) the number of shares of New Era
Common and/or common issuable upon exercise of New Era Options held by such
Shareholder or Optionholder.

event that, with notice or lapse of time or both, would constitute a material
default by New Era or, to New Era's knowledge, by any other party to such
leases. The New Era Disclosure Schedule contains a description of all real and
personal property leased or owned by New Era, describing its interest in each
property and, with respect to real property, a description of each parcel and a
summary description of the buildings, structures and improvements thereon. A
true, correct and complete copy of each New Era lease described in this Section
has been delivered to counsel for Interlink.

and condition useable, saleable or licensable in the ordinary course of
business, and (iii) is not subject to any write-down or write-off under any of

of inventory in the possession of wholesalers, distributors, retailers or other
customers, except for product returns in the ordinary course of business.

    3.10  Proprietary Rights.
          ------------------ 

          (a)  New Era owns all right, title and interest in, to, under and with
respect to, all intellectual property rights related to or used by New Era in

proprietary information owned by New Era, including, without limitation, all
proprietary rights developed or discovered in connection with or contained in
the products of New Era sold, offered, or under development as of the date of
this Agreement (the "New Era Products"), subject only to the rights of third
parties who may have independently developed similar proprietary rights, of
which New Era has no knowledge, and (iii) all of the computer software and data,
including, without limitation, all source and object codes, all developer notes
and documentation, all manuals and other user materials, all publishing rights

to derivations and modifications thereof, and all intangible data contained in
or stored on computer hardware related to or used by New Era in connection with
its business as of the Closing Date (collectively, the "Proprietary Rights"),
free and clear of all Encumbrances. The foregoing representation as it relates
to Third Party Technology, as defined in Section 3.10(b) below, is limited to
New Era's interest pursuant to the Third Party Licenses, as defined in Section
3.10(b) below, each of which is valid and enforceable, subject to the rules of
equity and rules relating to insolvency, and in full force and effect and which
grant New Era such rights to Third Party Technology, as defined in Section
3.10(b) below, as are employed in or necessary for the conduct of New Era's
business as presently conducted. None of New Era's licenses of Proprietary
Rights to third parties (i) assigns or otherwise transfers New Era's title to
any portion of any of the Proprietary Rights, or (ii) licenses any portion of
any of the Proprietary Rights on an exclusive basis.

          (b)  The New Era Disclosure Schedule contains an accurate and complete
description of (i) all patents, trademarks (with separate listings of registered
and unregistered trademarks), trade names, and registered copyrights in or
related to the New Era Products, all applications and registration statements
therefor, and a list of all licenses and other agreements relating thereto, and
(ii) all licenses and other agreements with third parties (the "Third Party
Licenses") relating to any patents, copyrights, technology, software, software
tools, know-how, processes, trade secrets, trademarks, service marks, trade
names or other proprietary rights that New Era is licensed or otherwise
authorized by such third parties to use, market, distribute or incorporate into
products distributed by New Era (such proprietary rights being collectively
referred to as the "Third Party Technology").

          (c)  All of New Era's trademark or trade name registrations related to
the New Era Products and all of New Era's copyrights in or related to any of the
New Era Products are valid and in full force and effect, and the execution and
delivery of, and the consummation of the transactions contemplated by, the
Transaction Documents will not alter or impair any such rights.

          (d)  New Era has taken the measures described in the New Era
Disclosure Schedule to protect the Proprietary Rights and the confidential
information of third parties. No claim has been asserted against New Era (and to
New Era's knowledge there are no claims that are likely to be asserted against
New Era or which have been or are likely to be asserted against others) by any
person challenging New Era's use or distribution of any patent, trademark, trade
name, copyright, trade secret, software, technology, know-how or process used by
New Era (including without limitation the Third Party Technology) or challenging
or questioning the validity or effectiveness of any license or agreement
relating thereto (including without limitation the Third Party Licenses). There
is no valid basis for any claim of the type specified in the immediately
preceding sentence that could in any way interfere with the continued
distribution of any of the New Era Products by New Era, Interlink or, to New
Era's knowledge, the continued enhancement or exploitation by them of any of the
New Era Products.

          (e)  None of the New Era Products or the use of any of the Proprietary
Rights by New Era in its business as conducted to the date hereof on the rights
of, constitutes misappropriation of, or in any way involves unfair competition
with respect to, any proprietary information or intangible property right of any
third party, including without limitation any patent, trade secret, copyright,
trademark or trade name, subject only to possible infringement of patents issued
after the date of this Agreement.

          (f)  No third party has any right to manufacture, reproduce,
distribute, market or exploit any of the New Era Products or any adaptations,
translations, or derivative works based on the New Era Products or any portion
thereof, except under licenses or agreements referenced in the New Era
Disclosure Schedule. No third party has any right to manufacture, reproduce,
distribute, market or exploit any work or material of which any of the New Era
Products is a "derivative work", as that term is defined in the United States
Copyright Act, Title 17, U.S.C. Section 101, except for the rights of third
parties to 

                                      -11-
<PAGE>
 
the Third Party Technology and except under the licenses or agreements
referenced in the New Era Disclosure Schedule. New Era is not a party or subject
to any agreement, obligation or commitment, written or oral, under which New Era
is obligated to manufacture for or supply to any third party any of the New Era
Products or components thereof, except under the licenses or agreements
referenced in the New Era Disclosure Schedule.

          (g)  All designs, drawings, specifications, source code, object code,
documentation, flow charts and diagrams incorporating, embodying or reflecting
any of the New Era Products at any stage of their development (the "New Era
Components") were written, developed and created solely and exclusively by
employees of New Era without the assistance of any third party or were created
by third parties who assigned ownership of their rights to New Era pursuant to
valid and enforceable agreements previously provided to counsel for Interlink
and listed on the New Era Disclosure Schedule.  New Era has at all times treated
the New Era Products and New Era Components as containing trade secrets, has at
all times used reasonable commercial efforts to protect such trade secrets and
has not disclosed or otherwise dealt with such items in such a manner as to
cause the loss of such trade secrets by their release into the public domain.
New Era has at all times used reasonable commercial efforts to protect the
confidentiality of all of its other confidential and proprietary information and
that of third parties that is or has been in its possession.

          (h)  To New Era's knowledge, no employee of New Era is in violation of
any term of any employment contract, patent disclosure agreement or any other
contract or agreement relating to the relationship of any such employee with New
Era or, to New Era's knowledge, any other party, because of the nature of the
business conducted by New Era to the date hereof.

          (i)  Each person currently employed by New Era (including consultants
and independent contractors, if any) that has or had access to confidential
information of New Era has executed and delivered to New Era a confidentiality
and non-disclosure agreement in the form previously provided to counsel for
Interlink. Such confidentiality and non-disclosure agreements constitute valid
and binding obligations of New Era and such person, enforceable in accordance
with their respective terms, subject to the rules of equity and rules relating
to insolvency.  To New Era's knowledge, neither the execution and delivery of
any such agreement, nor the carrying on of New Era's business by any such person
as an employee, consultant or independent contractor, as the case may be, has or
will conflict with or result in a breach of the terms, conditions or provisions
of, or constitute a default under, any contract, covenant or instrument under
which any of such persons is obligated.

          (j)  No product liability or warranty claim has been asserted or
threatened against New Era nor, to New Era's knowledge, is there any specific
situation, set of facts or occurrence that provides a basis for any such claim.

Employees Benefit Plan or any fund or assets related to the plan have been
undertaken and completed in accordance with plan terms and Applicable Law;

          -----------------------------------                            
delivery of this Agreement nor the consummation of the transactions contemplated
hereby will conflict with, or result in a material breach or violation of, any

hereby or thereby will directly have a material adverse effect on Interlink.

          ----------                                                         
Document to which Interlink is a party or any certificate furnished or to be
furnished pursuant thereto or in connection with the transactions contemplated
thereby contains or will contain any untrue statement of a material fact or

use such Principal Shareholder's commercially reasonable efforts to satisfy or
cause to be satisfied all the conditions precedent that are set forth in
Sections 11.1 and 11.3, and will use such Principal Shareholder's reasonable
commercial efforts to cause the transactions contemplated by this Agreement to
be consummated, and, without limiting the generality of the foregoing, to obtain
all consents and authorizations of third parties and to make all filings with,
and give all notices to, third parties which may be necessary or reasonably
required on its part in order to effect the transactions contemplated hereby.

     7.4  Disposition of Securities; Solicitation; Voting; Etc.  Except as
          ----------------------------------------------------            
provided in the lock-up letter of even date herewith, from and after the date
hereof, and unless this Agreement is terminated in accordance with Section 12
hereof, such Principal Shareholder shall:

          (a) not transfer, sell or assign to any person or entity, or agree in
any manner to transfer, sell or assign to any person or entity, or pledge,
encumber, deposit in a voting trust or grant a proxy with respect to any New Era
Common Shares currently or hereafter owned or controlled by such Principal
Shareholder without the prior written consent of Interlink;

                                      -24-
<PAGE>
 
          (b)  not solicit or enter into any agreement or arrangement with any
person or entity with respect to any transfer, sale or assignment of any New Era
Common Shares, except transfers, sales or assignments specifically contemplated
by this Agreement; and

          (c)  vote the New Era Common Shares currently or hereafter owned or
controlled by such Principal Shareholder against any merger amalgamation, or
similar transaction, (other than the transactions contemplated under this

recapitalization, liquidation or winding up of the Company in any case, at every
meeting of shareholders of New Era called therefor and at every adjournment or
postponement thereof (or in connection with any written consent in lieu of a
meeting relating to any such transaction).

The parties recognize and acknowledge that a breach by a Principal Shareholder
of this Section 7.4 will cause irreparable and material loss and damage to
Interlink and Sub, the amount of which is not readily determinable and that,
accordingly, each party agrees that, in addition to the reimbursement of all
expenses incurred by Interlink in connection with the preparation for and
consummation of the transactions contemplated hereby and the perfection of their
rights hereunder (including, without limitation, attorneys' and accountants'
fees and disbursements), the issuance of an injunction, an order requiring
specific performance or other equitable remedy shall be an appropriate remedy
for any such breach.

     7.5  Other Negotiations.  Between the date hereof and the Closing Date (or
          ------------------                                                   
the earlier termination of this Agreement pursuant to Section 12 hereof), such
Principal Shareholder will not, directly or indirectly, through any agent or
otherwise, take any action to solicit, initiate, seek, encourage or support any
inquiry, proposal or offer from, furnish any information to, or participate in
any negotiations with, any corporation, partnership, person or other entity or
group (other than Interlink) regarding any Acquisition Proposal.  If an
Acquisition Proposal is received by, or such information is requested from, such
Principal Shareholder, such Principal Shareholder shall promptly notify
Interlink of such fact.

pursuant to the Offer to Purchase are not prejudiced in any material respect by
such a manner of effecting the transactions contemplated hereby; provided any
obligations of such subsidiary shall be guaranteed in full by Interlink.  If the
transactions are effected through an Alberta subsidiary of Interlink this
document shall be deemed amended to refer to such subsidiary rather than
Interlink where the context so requires.

Payment Note from an Interlink account established by Interlink with the

Payment Notes to the Securityholders who have accepted Interlink's Offer to
Purchase and tendered their share certificates, option documents, and other
required documents to the Depository. In addition, Interlink will deliver the

                                   SECTION 13

          SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION
          -----------------------------------------------------------

     13.1 Survival of Representations and Warranties and Covenants.  If
          --------------------------------------------------------     
the Closing occurs, all of the representations and warranties made by New Era,
the Principal Shareholders, and Interlink contained in this Agreement shall
survive the Closing Date until one year from the Closing Date.

     13.2 Indemnification by New Era; Limitation of Liability.
          --------------------------------------------------- 

          (a)  Subject to the provisions and limitations herein contained, New
Era and the Securityholders who accept the consideration set forth in this
Agreement shall indemnify, defend and hold harmless Interlink, its officers,
directors, employees and attorneys, all current and future parents, subsidiaries
and Affiliates of Interlink, and their respective officers, directors, employees
and attorneys (all such persons and entities being collectively referred to as
the "Interlink Group") from and against any and all losses, damages, costs and
expenses (including reasonable legal fees and expenses) which any member of the
Interlink Group may sustain or incur which are occasioned by, caused by or arise
out of: (i) any inaccuracy in or breach of any of the representations,
warranties or covenants made by New Era or a Principal Shareholder in this
Agreement; or (ii) any inaccuracy or misrepresentation in the New Era Disclosure
Schedule in any certificate delivered by New Era or a Principal Shareholder
pursuant to this Agreement.

          (b)  The liability of New Era and its Securityholders under Section 13
shall be limited as follows: (i) claims shall be limited in the aggregate to
CDN$7,000,000; (ii) with respect to working capital and shareholders equity,
Interlink will conduct a post-closing audit immediately following the Closing,
and if the working capital and shareholders equity accounts together in the
post-closing audit deviate more than CDN$100,000 from the working capital and
shareholders equity accounts together on the New Era Unaudited Financials, then
Interlink shall be able to offset the entire amount of such deviation against
the amount owing on the Deferred Payment Notes; and, (iii) all claims based upon
breaches of representations, warranties, or covenants discovered prior to one
year after the Closing, and Interlink may offset such claims against the two
CDN$3,500,000 payments owing on the Deferred Payment Notes.  Offsets against the
Deferred Payment Notes shall be made only against the CDN $7,000,000 of such
notes which are subject to contingency, and then first against amounts due on
January 31, 1998.  The parties agree that, should claims by pending under this
Section 13 at the time any payment under the Deferred Payment Notes is due, such
payment shall be delayed to the extent of the amount of the claim only until
such time as that claim or claims is resolved.  As provided in Section 13.5
hereof, offset against the Deferred Payment Notes shall be Interlink's sole
remedy under this Section 13.  

                                      -30-
<PAGE>
 
Notwithstanding the foregoing, nothing in this Section 13 shall limit, in any
manner, any remedy at law or in equity to which Interlink shall be entitled
against New Era or any Principal Shareholder as a result of wilful fraud or
intentional misrepresentation by New Era, such Principal Shareholder or any of
their representatives or agents.

     13.3 Claims for Indemnification.  The party seeking indemnification (the 
          --------------------------                                    
"Indemnified Party") shall give each party from whom indemnification is
sought under this Section 13 (each an "Indemnifying Party") a written notice
("Notice of Claim") within 60 days following the discovery of any loss,
liability, claim or expense in respect of which the right to indemnification may
be claimed, but not later than 60 days after the first anniversary of the
Closing Date; provided, however, that the failure to give such notice within
such 60-day period shall not result in the waiver or loss of any right to bring
such claim hereunder after such period or relieve an Indemnifying Party from any
liability hereunder unless, and only to the extent that, an Indemnifying Party
is actually prejudiced by such failure.  In the event a claim is pending or
threatened or the Indemnified Party has a reasonable belief that there is a
valid basis for such a claim, the Indemnified Party may give written notice (a
"Notice of Possible Claim") of such claim to each Indemnifying Party, regardless
of whether a loss has arisen from such claim.  Any Notice of Claim or Notice of
Possible Claim shall set forth the representations, warranties, covenants and
agreements with respect to which the claim is made, the specific facts giving
rise to an alleged basis for the claim and the amount of liability asserted or
anticipated to be asserted by reason of the claim.

     13.4 Defense.  In the event that a claim for indemnification hereunder is
          -------                                                
based upon a claim by a third party asserted against the Indemnified Party, the
Indemnifying Party or Parties shall be entitled to control the defense thereof
and to settle any such action on such terms as it or they shall see fit so long
as (i) the Indemnified Party shall be released from any liability by reason of
such settlement, and (ii) such settlement does not restrict the business of New
Era or of Interlink; provided, however, that the Indemnified Party shall have
the right to approve counsel retained with respect to such defense (which
consent shall not unreasonably be withheld) and the right to participate in the
defense of such action at its own expense. The Indemnifying Party or Parties
shall receive full cooperation and access to all relevant and non-privileged
records of the Indemnified Party or Parties entitled to indemnification.

     13.5 Manner of Indemnification.  All indemnification by New Era under this
          -------------------------                                 
Section 13 shall be made exclusively by means of a claim against, the

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

     14.1 Governing Law.  This Agreement shall be governed by and construed in
          -------------                                          
accordance with the laws of the state of California, as such laws are applied to
agreements entered into and to be performed entirely within California by
California residents.

     14.2 Assignment; Binding upon Successors and Assigns.  None of the parties
          -----------------------------------------------

the benefit of the parties and their respective heirs, legal representatives,
successors and permitted assigns.

                                      -31-

     14.3 Severability.  If any provision of this Agreement, or the application 
          ------------                                             
thereof, shall for any reason and to any extent be held to be invalid or
unenforceable, the remainder of this Agreement and the application of such
provision to other persons or circumstances shall be interpreted so as best to
reasonably effect the intent of the parties. The parties further agree to
replace such invalid or unenforceable provision of this Agreement with a valid
and enforceable provision that will achieve, to the extent possible, the
economic, business and other purposes of the invalid or unenforceable provision.

     14.4 Entire Agreement.  This Agreement, the exhibits hereto, the documents
          ----------------                                           
referenced herein, and the exhibits thereto, constitute the entire understanding
and agreement of the parties with respect to the subject matter hereof and
thereof and supersede all prior and contemporaneous agreements or
understandings, inducements or conditions, express or implied, written or oral,
between the parties with respect hereto and thereto, including, without
limitation, the letter agreement dated December 1, 1995, as amended, between
Interlink and New Era, which is terminated and of no further force or effect.
The express terms hereof control and supersede any course of performance or
usage of the trade inconsistent with any of the terms hereof.

     14.5 Counterparts.  This Agreement may be executed in any number of
          ------------                                                  
counterparts, each of which shall constitute an original but all of which
together shall constitute one and the same instrument.

     14.6 Expenses.  Except as otherwise provided herein, the parties shall each
          --------                                                   
pay their own legal, accounting and financial advisory fees and other out-of-
pocket expenses incurred incident to the negotiation, preparation and carrying
out of this Agreement and the transactions herein contemplated.

     14.7 Other Remedies.  Except as otherwise provided herein, any and all
          --------------                                               
remedies herein expressly conferred upon a party shall be deemed cumulative with
and not exclusive of any other remedy conferred hereby or by law on such party,
and the exercise of any one remedy shall not preclude the exercise of any other.

     14.8 Amendment and Waivers.  Any term or provision of this Agreement may be
          ---------------------                                          
amended, and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or prospectively)
only by a writing signed by the party to be bound thereby. The waiver by a party
of any breach hereof for default in payment of any amount due hereunder or
default in the performance hereof shall not be deemed to constitute a waiver of
any other default or any succeeding breach or default.

     14.9 Waiver.  Any party hereto may, by written notice to the others: (i) 
          ------                                                          
waive any of the conditions to its obligations hereunder or extend the time for
the performance of any of the obligations or actions of the others, (ii) waive
any inaccuracies in the representations of the others contained in this
Agreement or in any documents delivered pursuant to this Agreement, (iii) waive
compliance with any of the covenants of the others contained in this Agreement,
or (iv) waive or modify performance of any of the obligations of the others. No
action taken pursuant to this Agreement, including without limitation any
investigation by or on behalf of any party, shall be deemed to constitute a
waiver by the party taking such action of compliance with any representation,
warranty, condition or agreement contained herein. Waiver of the breach of any
one or more provisions of this Agreement shall not be deemed or construed to be
a waiver of other breaches or subsequent breaches of the same provisions.

     14.10 Attorneys' Fees.  Should suit be brought to enforce or interpret any
           ---------------                                       
part of this Agreement, the prevailing party shall be entitled to recover, as an
element of the costs of suit and not as damages, reasonable attorneys' fees to
be fixed by the court (including without limitation, costs, expenses and fees on
any appeal). The prevailing party shall be the party entitled to recover its
costs of suit, 

                                      -32-
<PAGE>
 
regardless of whether such suit proceeds to final judgment. A party not entitled
to recover its costs shall not be entitled to recover attorneys' fees. No sum
for attorneys' fees shall be counted in calculating the amount of a judgment for
purposes of determining if a party is entitled to recover costs or attorneys'
fees.

     14.11 Jurisdiction of Disputes.  The parties hereto agree that all disputes
           ------------------------                                    
arising from this Agreement shall be adjudicated in the provincial courts of the
province of Alberta, Canada.

              FIRST AMENDMENT TO AGREEMENT AND PLAN OF ACQUISITION


     The Agreement and Plan of Acquisition dated December 13, 1995, by and among
the undersigned parties (the "Agreement") is hereby amended pursuant to Section
14.8 of the Agreement, as follows:

     1.   Section 2.3(a) of the Agreement is amended to read in full as follows:

          "(a) The Initial Payment Note.   Interlink will issue a promissory
               ------------------------                                     
     note due January 4, 1996 in the form attached to this Agreement as Exhibit
     B (the "Initial Payment Note").  The Initial Payment Note will be a single
     note for the benefit of all tendering Shareholders and Optionholders which
     such holders shall own beneficially in the following proportions (subject
     to Section 6.11 hereof):

               (i)  New Era Common.  The tendering holders of New Era Common 
                    --------------  
                    shall be entitled to receive out of the Initial Payment Note
                    an amount equal to the Gross Initial Payment (as defined
                    below) divided by the total number of shares of New Era
                    Common and Class A Common Shares issuable upon exercise of
                    New Era Options, and multiplied by the number of shares of
                    New Era Common held by such holder.

               (ii) New Era Options.  The tendering holders of New Era Options
                    ---------------                                           
                    shall be entitled to receive out of the Initial Payment Note
                    an amount equal to: (A) the Gross Initial Payment (as
                    defined below) divided by the total number of New Era Common
                    and Class A Common Shares issuable upon exercise of New Era
                    Options, minus (B) $15.00, then multiplied by (C) the number
                    of Class A Common Shares of New Era issuable upon exercise
                    of such New Era Option.

          The principal amount of the Initial Payment Note shall equal the sum
     total of all the beneficial interests, set forth in Sections 2.3(a)(i) and
     2.3(a)(ii) above, of the tendering holders of New Era Common and New Era
     Options.

          The Depository will be instructed to make payment to the tendering
     Shareholders and Optionholders on January 4, 1996 of the amounts due under
     the Initial Payment Note from amounts deposited by Interlink with the
     Depository at Closing, provided, however, that the Depository will be
     instructed to pay to New Era out of each Shareholder payment any amounts of
     principal and accrued interest on any obligations to New Era incurred for
     the purchase of such shares outstanding at Closing.
<PAGE>
 
          The "Gross Initial Payment" shall equal CDN $15,000,000, minus
     $384,000 to be paid at the Closing by Interlink to Concord Corporation as
     part of the Fees, minus an aggregate of $150,000 for the estimated fees of
     the Depository, Ernst & Young as accountants for New Era, and Macleod Dixon
     as counsel to New Era, which will be paid when due by Interlink, minus the
     amount paid by New Era prior to the Closing in redemption of 50,000 shares
     of New Era Class A Preferred Stock outstanding as of the date of this
     Agreement (the remaining 20,000 shares of New Era Class A Preferred Stock
     are also to be redeemed prior to Closing in exchange for an outstanding
     note payable to New Era), minus the amount paid by Interlink at or prior to
     the Closing to purchase 30,000 shares of New Era Class B Preferred Stock
     outstanding as of the date of this Agreement, and plus the aggregate
     exercise price of all New Era Options outstanding as of the Closing."

     2.   Section 6.11 of the Agreement is amended to add the following sentence
at the end of such Section:

     "In the event that New Era sells these assets prior to the Closing Date,
     but the proceeds of such sale are not distributed to the Shareholders and
     Securityholders by the Closing Date, Interlink will adjust the principal
     amount of the Initial Payment Note by the net value of the proceeds from
     the sale of these assets as agreed in writing by Interlink and New Era
     prior to closing, and the price per Class A Common Share and the price per
     New Era Option paid under the Initial Payment Note will be adjusted
     accordingly."

     3.   Section 6.13 of the Agreement is amended to read in full as follows:

          "Purchase of Class B Preferred.  Interlink will, prior to the Closing,
           -----------------------------                                        
     offer to purchase all 30,000 outstanding shares of New Era Class B
     Preferred Stock for an aggregate consideration of $346,500."

     4.   Section 11.3(h) of the Agreement shall be deleted and Section 11.3(i)
shall be redesignated as Section 11.3(h).

     5.   The following new Section 3.27 shall be added to Section 3:

     "3.27  Western Economic Diversification Consent.  To the extent that, as of
            ----------------------------------------                            
     the Closing Date, New Era shall not have obtained written approval from
     Western Economic Diversification that the loan from such entity will
     continue in New Era without change in its terms or payment conditions, New
     Era represents and warrants that the lack of such consent will not have an
     adverse effect on the post-closing financial condition of New Era.  An
     adverse effect on financial condition shall include but not be limited to
     the amounts paid to replace such loan on similar economic terms should
     payment of the loan be accelerated for failure to obtain such consent."

                                      -2-
<PAGE>
 
     This amendment may be executed in one or more counterparts, each of which
shall constitute an original, but all of which together shall constitute one in
the same instrument.

     IN WITNESS WHEREOF, the parties have executed this First Amendment to
Agreement and Plan of Acquisition on December 29, 1995.

                        party of its or her intent not to renew at least 9O days

                        terminated and after the 9O day notice period has
                        expired, you will be entitled to receive payment as
                        outlined below.

                        Employee's employment with the Company shall be
                        terminated (i) by reason of Employee's death, (2) by
                        reason of Employee becoming permanently disabled as
                        defined in Paragraph 7, or (3) for cause. For purposes
                        of the preceding sentence, "cause" shall be deemed to
                        exist if, and only if; (I) Employee willfully refuses to
                        perform services hereunder; (ii) Employee engages in
                        acts of dishonesty or fraud in connection with her
                        services hereunder; or (iii) Employee engages in other
                        serious misconduct of such a nature that continued
                        employment of Employee may reasonably be expected to
                        adversely affect the business or properties of the
                        Company.

                        If the Company determines that a reason constituting
                        cause for termination has occurred, it shall give
                        Employee written notice of at least 30 days prior to the
                        proposed date of termination of employment. In the event
                        of termination of employment pursuant to this
                        subparagraph (a), all obligations of the Company shall
                        hereunder terminate.

                        If Employee's employment with the Company shall
                        terminate other than for cause, voluntary termination,
                        permanent disability, death or retirement on or after
                        age 65, Employee shall be entitled to severance pay
                        equal to six months base salary at the then current
                        rate. Notwithstanding the foregoing, in the event
                        Employee's employment is terminated within 12 months
                        following a merger, sale of assets or sale of shares as
                        specified in subparagraph (d) below, Employee shall be
                        entitled to receive severance pay equal to the greater
                        of (I) a number of months of base salary continuance at
                        the then current rate equal to 12 minus the number of
                        months elapsed from the closing date of such merger,
                        sale of assets or sale of shares, and (ii) 6 months base
                        salary at the then current rate.

                        If Employee's employment with the company shall
                        terminate for cause, or due to death, disability,
                        voluntary termination or retirement on or after age 65,
                        any portion of her fixed salary which is earned but
                        unpaid as of the date of death or retirement shall be
                        paid to Employee, or her designated beneficiary in the
                        event of her death, or if
<PAGE>
 
                        none to her then living Spouse, or if none, to the duly
                        appointed personal representative of her estate.

                        If Employee's employment with the Company shall
                        terminate within 12 months following the acquisition of
                        the Company by merger, sale of assets or sale of shares
                        pursuant to which the shareholders of the company retain
                        or receive in such transaction less than 50% of the
                        outstanding voting equity securities of the surviving
                        corporation (but specifically excluding any financings
                        involving Shareholders of the Company), Employee shall
                        be entitled to receive 100% acceleration of unvested
                        stock options or with mutual agreement, the Board may
                        offer equivalent compensation. If the accelerated
                        vesting of options or granting of equivalent
                        compensation precludes a pooling treatment of the
                        acquisition, the Board must act in the interest of the
                        Company and perfect this compensation through alternate
                        solutions to the Employee.

This offer letter supersedes all other offer letters and compensation plans.
This does not Supersede the Management and Key Employee Cash Bonus Agreement,
the Employee Non-Disclosure Agreement and Indemnification Agreement's previously
signed.

Please sign this letter to indicate your acceptance of this new position
effective February 1, 1996.

                                                Issuance Date: December 15, 1993

                                                   Void After: December 15, 1998


          1.   Number and Price of Shares Subject to Warrant.  Subject to the 
               --------------------------------------------- 
terms and conditions of this Warrant, Menlo Ventures IV, L.P. (the "Holder"),
whose address is 3000 Sand Hill Road, Bldg. 4, Ste. 100, Menlo Park, California
94025 (fax no. (415) 854-7059), shall be entitled to purchase from Interlink
Computer Sciences, Inc., a California corporation (the "Company"), up to Thirty-
one Thousand Six Hundred Sixty-Seven (31,667) fully paid and non-assessable
shares of the Company's Common Stock (the "Shares"), at an exercise price of
$0.45 per share (which number of Shares and purchase price are subject to
adjustment as described below). The purchase price of one share of Common Stock
payable from time to time upon the exercise of this Warrant (whether such price
be the price specified above or an adjusted price determined as hereinafter
provided) is referred to herein as the "Exercise Price."

          2.   Expiration Date.  This Warrant shall expire on the earlier to 
               ---------------                                 
occur of (i) December 15, 1998; (ii) the closing of an initial public offering
of shares of the Company's Common Stock provided that (a) the per share initial
public offering price is equal to or greater than the minimum per share price
necessary to include the Company's Common Stock on the NASDAQ National Market
System as in effect at the time of the public offering and (b) that the gross
proceeds to the Company from the offering (before deduction or underwriting
discounts and commissions and expenses of the offering) are at least $10
million; or (iii) the closing of a merger or reorganization of the Company
unless the pre-merger/reorganization holders of the Company's voting securities
own, immediately following such merger or reorganization, at least a majority of
the outstanding voting securities of the Company or its successor, it being
understood that the Holder shall have the opportunity, by giving conditional
notice of exercise, to exercise this Warrant concurrent with the closing of a
transaction described in this clause (iii). The earlier to occur of such dates
is referred to herein as the "Expiration Date."
<PAGE>
 
          3.   Exercise of Warrant.
               -------------------

               (a)  This Warrant may be exercised by Holder in whole or in part
at any time prior to the Expiration Date by the surrender of this Warrant
together with a completed and signed Notice of Exercise and payment in full of
the Exercise Price as to the shares being purchased at the principal office of
the Company. Payment of the Exercise Price shall be made by cash, by bank or
certified check or, in lieu or exercising this Warrant for cash or check, Holder
may elect to receive shares equal to the value of this Warrant (or the portion
thereof being exercised) in which event the Company shall issue to Holder a
number of Shares computed using the following formula:

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

Where:    X =  The number of Shares to be issued to Holder;

          Y =  The gross number of Shares purchasable under this Warrant or, in
               the event of a partial exercise, the gross number of shares as to
               which this Warrant is being exercised;

          A =  The fair market value of one Share; and

          B =  Exercise Price (as adjusted to the date of such calculations).

          For purposes of this Section, fair market value of the Company's
Common Stock shall mean the average of the closing bid and asked prices of the
Company's Common Stock quoted in the Over-The-Counter Market Summary, or the
closing price quoted on any exchange on which the Common Stock is listed,
whichever is applicable, as published in the Western Edition of The Wall Street
                                                                ---------------
Journal for the ten trading days prior to the date of determination of fair
- -------                                                                     
market value. If the Common Stock is not traded Over-The-Counter or on an
exchange, the fair market value shall be the price per share which the Company
could obtain from a willing buyer for shares sold by the Company from authorized
but unissued shares, as such price shall be agreed by the Company and the
Holder.

               (b)  The Company shall, within ten (10) days after exercise of
this Warrant, prepare a certificate for the shares of Common Stock purchased in
the name of the Holder of this Warrant, or as such Holder may direct (subject to
the restrictions upon transfer contained herein and upon payment by such holder
hereof of any applicable transfer taxes). Shares issuable upon exercise hereof
shall be deemed issued on the date on which the Notice of Exercise, together
with payment of the Exercise Price of the Shares purchased (if applicable) are

                                      -2-
<PAGE>
 
delivered to the Company notwithstanding any delay issuing certificates
therefor.

               (c)  Upon partial exercise hereof, a new warrant or warrants
containing the same date and provisions as this Warrant shall be issued by the
Company to the registered holder for the number of Shares with respect to which
this Warrant shall not have been exercised.

          4.   Adjustments.
               -----------  
               (a)  Adjustments for Combinations or Subdivisions of Common 
                    ------------------------------------------------------
Stock.  In the event the Company at any time or from time to time after the
- -----
date hereof shall declare or pay any dividend on the Common Stock payable in
Common Stock or in any right to acquire Common Stock, or shall effect a
subdivision of the outstanding shares of Common Stock into a greater number of
shares of Common Stock (by stock split, reclassification or otherwise), or in
the event the outstanding shares of Common Stock shall be combined or
consolidated, by reclassification or otherwise, into a lesser number of shares
of Common Stock, then the Exercise Price in effect and the number of Shares
subject to this Warrant immediately prior to such event shall, concurrently with
the effectiveness of such event, be proportionately decreased or increased, as
appropriate.

               (b)  Adjustments for Reorganizations, Mergers, Etc.  In case of 
                    ---------------------------------------------
any reorganization or any reclassification of the capital stock of the Company,
any consolidation or merger of the Company with or into another entity or
entities, or the conveyance of all or substantially all of the assets of the
Company to another corporation, this Warrant shall thereafter be exercisable for
the number of shares of stock or other securities or property (including cash)
to which a holder of the number of Shares deliverable upon exercise of this
Warrant would have been entitled upon the record date of (or date of, if no
record date is fixed) such reorganization, reclassification, consolidation,
merger or conveyance; and, in any case, appropriate adjustment (as determined by
the Board of Directors) shall be made in the application of the provisions
herein set forth with respect to the rights and interests thereafter of the
holder(s) of this Warrant, to the end that the provisions set forth herein shall
thereafter be applicable, as nearly as equivalent as is practicable, in relation
to any shares of stock or the securities or property (including cash) thereafter
deliverable upon the exercise of this Warrant.

               (c)  Certificates as to Adjustments.  Upon the occurrence of 
                    ------------------------------   
each adjustment or readjustment of the Exercise Price or the number of Shares
subject to this Warrant pursuant to this Section 4, the Company at its expense
shall promptly compute such adjustment or readjustment in accordance with the
terms hereof and prepare and furnish to each Holder a certificate setting forth
such adjustment or readjustment and showing in detail the facts upon which such

                                      -3-
<PAGE>
 
adjustment or readjustment is based. The Company shall, upon the written request
at any time of any Holder, furnish or cause to be furnished to such Holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
Exercise Price at the time in effect, and (iii) the number or Shares subject to
this Warrant and the amount, if any, or other property which at the time would
be received upon exercise of this Warrant.

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

          6.   Transfer of Warrant.  Subject to the 1imitations provided for 
               -------------------   
in Section 7 herein, this Warrant and all rights hereunder may be transferred in
whole or in part by the Holder.

          7.   Compliance with Securities Laws.
               -------------------------------  

               (a)  Holder acknowledges that it understands that this Warrant
and the Shares have not been registered under the Act and accordingly must be
held indefinitely unless they are subsequently registered under the Act or an
exemption from such registration is available. Holder represents and warrants
that this Warrant is being acquired for investment, for Holder's own account,
and without any present intention to sell or distribute this Warrant or the
Shares.

               (b)  It shall be a condition to any transfer or exercise of this
Warrant that the Company shall have received, at the time of such transfer or
exercise, a representation in writing that this Warrant (or portion hereof
transferred) or the shares of Common Stock being issued upon such exercise, as
the case may be, are being acquired for investment and not with a view to any
sale or distribution thereof, or a statement of the pertinent facts covering
any proposed distribution thereof.

               (c)  It shall be a further condition to any transfer of this
Warrant or of any or all of the shares of Common Stock issued upon exercise of
this Warrant, other than a transfer registered under the Act (as defined below),
that the Company shall have received a legal opinion, in form and substance
satisfactory to the Company and its counsel, reciting the pertinent
circumstances surrounding the proposed transfer and stating that such transfer

                                                Issuance Date: December 15, 1993
                                                   
                                                   Void After: December 15, 1998

          ---------------------------------------------
and conditions of this Warrant, Menlo Evergreen V, L.P. (the "Holder"), whose
address is 3000 Sand Hill Road, Bldg. 4, Ste. 100, Menlo Park, California 94025
(fax no. (415) 854-7059), shall be entitled to purchase from Interlink Computer
Sciences Inc., a California corporation (the "Company"), up to Thirty-one
Thousand Six Hundred Sixty-Seven (31,667) fully paid and non-assessable shares
of the Company's Common Stock (the "Shares"), at an exercise price of
$0.45 per share (which number of Shares and purchase price are subject to
adjustment as described below). The purchase price of one share of Common Stock
payable from time to time upon the exercise of this Warrant (whether such price
be the price specified above or an adjusted price determined as hereinafter
provided) is referred to herein as the "Exercise Price."

     2.   Expiration Date.   This Warrant shall expire on the earlier to occur
          ---------------
of (i) December 15, 1998; (ii) the closing of an initial public offering of
shares of the Company's Common Stock provided that (a) the per share initial
public offering price is equal to or greater than the minimum per share price
necessary to include the Company's Common Stock on the NASDAQ National Market
System as in effect at the time of the public offering and (b) that the gross
proceeds to the Company from the offering (before deduction of underwriting
discounts and commissions and expenses of the offering) are at least $10
million; or (iii) the closing of a merger or reorganization of the Company
unless the pre-merger/reorganization holders of the Company's voting securities
own, immediately following such merger or reorganization, at least a majority of
the outstanding voting securities of the Company or its successor, it being
understood that the Holder shall have the opportunity, by giving conditional
notice of exercise, to exercise this Warrant concurrent with the closing of a
transaction described in this clause (iii).  The earlier to occur of such dates
is referred to herein as the "Expiration Date."
<PAGE>
 
     3.   Exercise of warrant.
          ------------------- 

          (a)  This Warrant may be exercised by Holder in whole or in part at
any time prior to the Expiration Date by the surrender of this Warrant together
with a completed and signed Notice of Exercise and payment in full of the
Exercise Price as to the shares being purchased at the principal office of the
Company.  Payment of the Exercise Price shall be made by cash, by bank or
certified check or, in lieu of exercising this Warrant for cash or check, Holder
may elect to receive shares equal to the value of this Warrant (or the portion
thereof being exercised) in which event the Company shall issue to Holder a
number of Shares computed using the following formula:

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

Where:    X =  The number or Shares to be issued to Holder:

          Y =  The gross number of Shares purchasable under this Warrant or,
               in the event of a partial exercise, the gross number of shares as
               to which this Warrant is being exercised;

          A =  The fair market value of one Share; and

          B =  Exercise Price (as adjusted to the date of such calculations).

               For purposes of this Section, fair market value of the Company's
Common Stock shall mean the average of the closing bid and asked prices of the
Company's Common Stock quoted in the Over-The-Counter Market Summary, or the
closing price quoted on any exchange on which the Common Stock is listed,
whichever is applicable, as published in the Western Edition of The Wall Street
                                                                ---------------
Journal for the ten trading days prior to the date of determination of fair
- -------
market value.  If the Common Stock is not traded Over-The-Counter or on an
exchange, the fair market value shall be the price per share which the Company
could obtain from a willing buyer for shares sold by the Company from authorized
but unissued shares, as such price shall be agreed by the Company and the
Holder.

          (b)  The Company shall, within ten (10) days after exercise of this
Warrant, prepare a certificate for the shares of Common Stock purchased in
the name of the Holder of this Warrant, or as such Holder may direct (subject to
the restrictions upon transfer contained herein and upon payment by such holder
hereof of any applicable transfer taxes).  Shares issuable upon exercise hereof
shall be deemed issued on the date on which the Notice of Exercise, together
with payment of the Exercise Price of the Shares purchased (if applicable) are

                                      -2-
<PAGE>
 
delivered to the Company notwithstanding any delay in issuing certificates
therefor.

          (c)  Upon partial exercise hereof, a new warrant or warrants
containing the same date and provisions as this Warrant shall be issued by the
Company to the registered holder for the number of Shares with respect to which
this Warrant shall not have been exercised.

     4.   Adjustments.
          -----------  

          (a)  Adjustments for Combinations or Subdivisions of Common Stock.
               ------------------------------------------------------------
In the event the Company at any time or from time to time after the date hereof
shall declare or pay any dividend on the Common Stock payable in Common Stock or
in any right to acquire Common Stock, or shall effect a subdivision of the
outstanding shares of Common Stock into a greater number of shares of Common
Stock (by stock split, reclassification or otherwise), or in the event the
outstanding shares of Common Stock shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of shares of Common
Stock, then the Exercise Price in effect and the number of Shares subject to
this Warrant immediately prior to such event shall, concurrently with the
effectiveness of such event, be proportionately decreased or increased, as
appropriate.

          (b)  Adjustments for Reorganizations, Mergers. Etc.  In case of any
               ---------------------------------------------                
reorganization or any reclassification of the capital stock of the Company, any
consolidation or merger of the Company with or into another entity or entities,
or the conveyance of all or substantially all of the assets of the Company to
another corporation, this Warrant shall thereafter be exercisable for the number
of shares of stock or other securities or property (including cash) to which a
holder of the number of Shares deliverable upon exercise of this Warrant would
have been entitled upon the record date of (or date of, if no record date is
fixed) such reorganization, reclassification, consolidation, merger or
conveyance; and, in any case, appropriate adjustment (as determined by the Board
of Directors) shall be made in the application of the provisions herein set
forth with respect to the rights and interests thereafter of the holder(s) of
this Warrant, to the end that the provisions set forth herein shall thereafter
be applicable, as nearly as equivalent as is practicable, in relation to any
shares of stock or the securities or property (including cash) thereafter
deliverable upon the exercise of this Warrant.

          (c)  Certificates as to Adjustment.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Exercise Price or the number of Shares subject
to this Warrant pursuant to this Section 4, the Company at its expense shall
promptly compute such adjustment or readjustment in accordance with the terms
hereof and prepare and furnish to each Holder a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such

                                      -3-
<PAGE>
 
adjustment or readjustment is based.  The Company shall, upon the written
request at any time of any Holder, furnish or cause to be furnished to such
Holder a like certificate setting forth (i) such adjustments and readjustments,
(ii) the Exercise Price at the time in effect, and (iii) the number of Shares
subject to this Warrant and the amount, if any, or other property which at the
time would be received upon exercise of this Warrant.

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

     6.  Transfer of Warrant.  Subject to the limitations provided for in
         -------------------                                              
Section 7 herein, this Warrant and all rights hereunder may be transferred in
whole or in part by the Holder. 

     7.   Compliance with Securities Laws.
          -------------------------------

          (a)  Holder acknowledges that it understands that this Warrant and the
Shares have not been registered under the Act and accordingly must be held
indefinitely unless they are subsequently registered under the Act or an
exemption from such registration is available. Holder represents and warrants
that this Warrant is being acquired for investment, for Holder's own account,
and without any present intention to sell or distribute this Warrant or the
Shares.

          (b)  It shall be a condition to any transfer or exercise of this
Warrant that the Company shall have received, at the time of such transfer or
exercise, a representation in writing that this Warrant (or portion hereof
transferred) or the shares of Common Stock being issued upon such exercise, as
the case may be, are being acquired for investment and not with a view to any
sale or distribution thereof, or a statement of the pertinent facts covering any
proposed distribution thereof.

          (c)  It shall be a further condition to any transfer of this Warrant
or of any or all of the shares of Common Stock issued upon exercise of this
Warrant, other than a transfer registered under the Act (as defined below), that
the Company shall have received a legal opinion, in form and substance
satisfactory to the Company and its counsel, reciting the pertinent
circumstances surrounding the proposed transfer and stating that such transfer
is exempt from the prospectus and the registration requirements of the Act.

          (d)  Each certificate evidencing the shares of Common Stock issued
upon exercise of this Warrant, or upon any transfer of such

                                      -4-
<PAGE>
 
the Company and its counsel, restricting the transfer of such shares to sales or
other dispositions exempt from the requirements of the Act.

          (e)  It shall be a further condition to any transfer of this Warrant
that the transferee shall receive and accept a Warrant, of like tenor and date,
executed by the Company.

     8.   No Stockholder Rights.   This Warrant shall not entitle holder to any
          ---------------------
of the rights of a shareholder of the Company.

     9.  Registration Rights.  Holder shall be entitled, with respect to the
         -------------------
Shares, to registration rights substantially as set forth in that certain
Shareholders' Agreement dated as of October 20, 1992, between the Company,

Borrower:   Interlink Computer Sciences, Inc.

Subject:    Credit Terms and Conditions ("Agreement")

Gentlemen:

To induce you to make loans to the undersigned (herein called "Borrower"), and
in consideration of any loan or loans you, in your sole discretion, may make to
Borrower, Borrower warrants and agrees as follows:

A.   Borrower represents and warrants that:

     1.   EXISTENCE AND RIGHTS.

Borrower is a corporation. Borrower is duly organized and existing and in good
standing under the laws of the State of California and is authorized and in good
standing to do business in the State of California.  Borrower has powers and
adequate authority, rights and franchises to own its property and to carry on
its business as now conducted, and is duly qualified and in good standing in
each State in which the character of the properties owned by it therein or the
conduct of its business makes such qualification necessary, and Borrower has the
power and adequate authority to make and carry out this Agreement. Borrower has
no investment in any other business entity, except as previously disclosed to
Bank.

     2.   AGREEMENT AUTHORIZED.  The execution, delivery and performance of this
Agreement are duly authorized and do not require the consent or approval of any
governmental body or other regulatory authority; are not in contravention of or
in conflict with any law or regulation or any term or provision of Borrower's
articles of incorporation, by-laws, or Articles of Association, as the case may
be, and this Agreement is the valid, binding and legally enforceable obligation
of Borrower in accordance with its terms.

     3.   NO CONFLICT.  The execution, delivery and performance of this
Agreement are not in contravention of or in conflict with any agreement,
indenture or undertaking to which Borrower is a party or by which it or any of
its property may be bound or affected, and do not cause any lien, charge or
other encumbrance to be created or imposed upon any such property by reason
thereof.

     4.   LITIGATION.  There is no litigation or other proceeding pending or
threatened against or affecting Borrower, and Borrower is not in default with
respect to any order, writ, injunction, decree or demand of any court or other
governmental or regulatory authority.

     5.   FINANCIAL CONDITION.  The balance sheet of Borrower as of 2/29/96, and
the related profit and loss statement for the 1 month ended on that date, a copy
of which has heretofore been delivered to you by Borrower, and all other
statements and data submitted in writing by Borrower to you in connection with
this request for credit are true and correct, and said balance sheet and profit
and loss statement truly present the financial condition of Borrower as of the
date thereof and the results of the operations of Borrower for the period
covered thereby, and in all material respects, have been prepared in accordance
with generally accepted accounting principles on a basis consistently
maintained. Since such date there have been no materially adverse changes in the
financial condition or business of Borrower.  Borrower has no knowledge of any
liabilities, contingent or otherwise, at such date not reflected in said balance
sheet, and Borrower has not entered into any special commitments or substantial
contracts which are not reflected in said balance sheet, other than in the
ordinary and normal course of its business, which may have a materially adverse
effect upon its financial condition, operations or business as now conducted.

     6.   TITLE TO ASSETS.  Borrower has good title to its assets, and the same
are not subject to any liens or encumbrances other than those permitted by
Section C.3 hereof.

     7.   TAX STATUS.  Borrower has no liability for any delinquent state, local
or federal taxes, and if Borrower has contracted with any government agency,
Borrower has no liability for renegotiation of profits.

     8.   TRADEMARKS, PATENTS.  Borrower, as of the date hereof, possesses all
necessary trademarks, trade names, copyrights, patents, patent rights, and
licenses to conduct its business as now operated, without any known conflict
with the valid trademarks, trade names, copyrights, patents and license rights
of others.

     9.   REGULATION U.  The proceeds of this loan shall not be used to purchase
or carry margin stock (as defined with Regulation U of the Board of Governors of
the Federal Reserve system).

     2.   INSURANCE.  Maintain public liability, property damage and workers'
compensation insurance and insurance on all its insurable property against fire

maintained by similar businesses.

     3.   TAXES AND OTHER LIABILITIES.  Pay and discharge, before the same
become delinquent and before penalties accrue thereon, all taxes, assessments
and governmental charges upon or against it or any of its properties, and all
its other liabilities at any time existing, except to the extent and so long as:

(a)  The same are being contested in good faith and by appropriate proceedings
     in such manners as not to cause any materially adverse effect upon its
     financial condition or the loss of any right of redemption from any sale
     thereunder, and

     the figures for the corresponding date and period in the previous fiscal
     year, prepared in accordance with generally accepted accounting principles

     stating that Borrower has performed and observed each and every covenant
     contained in this Letter of Inducement to be performed by it and that no
     event has occurred and no condition then exists which constitutes an event
     of default hereunder or would constitute such an event of default upon the
     lapse of time or upon the giving of notice and the lapse of time specified
     herein, or, if any such event has occurred or any such condition exists,
     specifying the nature thereof;

     reasonably may request from time to time.

(g)  Notice of Default. Promptly notify the Bank in writing of the occurrence of
     any event of default hereunder or any event which upon notice and lapse of

character of its business; or make any change in its executive management.

     in such amounts as may be determined by Bank up to, but not exceeding in
     the aggregate unpaid principal balance, the following Borrowing Base:

                   80% of Eligible Domestic Accounts                           
                   60% of Eligible Foreign Accounts up to a $1,000,000 maximum.
                   and in no event more than $5,000,000.

2.   The amount of each loan made by Bank to Borrower hereunder shall be debited
     to the loan ledger account of Borrower maintained by Bank (herein called
     "Loan Account") and Bank shall credit the Loan Account with all loan
     repayments made by Borrower. Borrower promises to pay Bank (a) the unpaid
     balance of Borrower's Loan Account on November 29, 1996 and (b) on or
     before the tenth day of each month, interest on the average daily unpaid
     balance of the Loan Account during the immediately preceding month at the

     of interest which Bank has announced as its prime lending rate ("Prime
     Rate") which shall vary concurrently with any change in such Prime Rate.
     Interest shall be computed at the above rate on the basis of the actual
     number of days during which the principal balance of the loan account is
     outstanding divided by 360, which shall for interest computation purposes
     be considered one year. Bank at its option may demand payment of any or all
     of the amount due under the Loan Account including accrued but unpaid
     interest at any time. Such notice may be given verbally or in writing and
     should be effective upon receipt by Borrower. In the event of a default the
     interest rate shall be increase to the rate which is five (5) percent in
     excess of the above rate. The amount of interest payable each month by
     Borrower shall not be less than a minimum monthly charge of $300.00. If any
     payment of interest or principal due hereunder is ten or more days
     delinquent, Borrower shall pay to Bank a late charge of five percent (5%)
     of the payment so due and unpaid, in addition to the payment. Bank is
     hereby authorized to charge Borrower's deposit account(s) with Bank, if
     amounts due are on deposit in collected funds, for all sums due Bank under
     this Agreement.

3.   Requests for loans hereunder shall be in writing duly executed by Borrower
     in a form satisfactory to Bank and shall contain a certification setting
     forth the matters referred to in Section 1, which shall disclose that
     Borrower is entitled to the amount of loan being requested.

     funds (and not from the proceeds of Accounts included in the Borrowing
     Base or Inventory) for application to Borrower's Loan Account or any other

     Any partial prepayment shall be applied to the installments, if any, in
inverse order of maturity. Should default be made in the payment of principal or
interest when due, or in the performance or observance, when due, of any item,
covenant or condition of any deed of trust, security agreement or other
agreement (including amendments or extensions thereof) securing or pertaining to
this note, at the option of the holder hereof and without notice or demand, the
entire balance of principal and accrued interest then remaining unpaid shall 
(a) become immediately due and payable, and (b) thereafter bear interest, until
paid in full, at the increased rate of 5% per year in excess of the rate
provided for above, as it may vary from time to time.

     Defaults shall include, but not be limited to, the failure of the maker(s)
to pay principal or interest when due; the filing as to each person obligated
hereon, whether as maker, co-maker, endorser or guarantor (individually or
collectively referred to as the "Obligor") of a voluntary or involuntary
petition under the provisions of the Federal Bankruptcy Act; the issuance of any
attachment or execution against any asset of any Obligor; the death of any
Obligor; or any deterioration of the financial condition of any Obligor which
results in the holder hereof considering itself, in good faith, insecure.


[_]  If any installment payment or principal balance payment due hereunder is
delinquent ten or more days, Obligor agrees to pay a late charge in the amount
of 5% of the payment so due and unpaid, in addition to the payment; but nothing
in this paragraph is to be construed as any obligation on the part of the holder
of this note to accept payment of any installment past due or less than the
total unpaid principal balance after maturity.

     If this note is not paid when due, each Obligor promises to pay all costs
and expenses of collection and reasonable attorney's fees incurred by the holder
hereof on account of such collection, plus interest at the rate applicable to
principal, whether or not suit is filed hereon. Each Obligor shall be jointly
and severally liable hereon and consents to renewals, replacements and
extensions of time for payment hereof, before, at or after maturity; consents to
the acceptance, release or substitution of security for this note; and waives
demand and protest and the right to assert any statute of limitations. Any
married person who signs this note agrees that recourse may be had against
separate property for any obligations hereunder. The indebtedness evidenced
hereby shall be payable in lawful money of the United States. In any action
brought under or arising out of this note, each Obligor, including successor(s)
or assign(s) hereby consents to the application of California law, to the
jurisdiction of any competent court within the State of California, and to
service of process by any means authorized by California law.

     No single or partial exercise of any power hereunder, or under any deed of
trust, security agreement or other agreement in connection herewith shall
preclude other or further exercises thereof or the exercise of any other such
power. The holder hereof shall at all times have the right to proceed against
any portion of the security for this note in such order and in such manner as
such holder may consider appropriate, without waiving any rights with respect to
any of the security. Any delay or omission on the part of the holder hereof in
exercising any right hereunder, or under any deed of trust, security agreement
or other agreement, shall not operate as a waiver of such right, or of any other
right, under this note or any deed of trust, security agreement or other
agreement in connection herewith.
