ITEM 1.  Business

     SeaChange International, Inc. ("SeaChange"or the "Company") develops,
markets and supports products to manage, store and distribute digital video for
television operators, broadcast and telecommunications companies. The Company's
products utilize its proprietary distributed application software and standard
industry components to automate the management and distribution of short- and
long-form video streams including advertisements, movies, news updates and other
video programming requiring precise, accurate and continuous execution. The
Company's digital video products with their state-of-the-art electronic storage
and retrieval capabilities are designed to provide higher image quality and to
be more reliable, easier to use and less expensive than analog tape-based
systems. In addition, SeaChange's products enable its customers to increase
revenues by offering more targeted services such as geography-specific spot
advertising and video-on-demand movies.

     SeaChange's products address a number of specific markets. The SeaChange
SPOT System is the leading digital advertisement and other short-form video
insertion system for the multichannel television market in terms of
installations in the United States, based on currently available industry
sources and the Company's internal data. A majority of SeaChange's customers
consist of major cable television operators and telecommunications companies in
the United States. The SeaChange SPOT System converts analog video forms such as
advertisements and news updates to digital video forms. It stores them in remote
or local digital libraries, and inserts them automatically into television
network streams. The SPOT System provides high run-rate accuracy and video image
quality, permits geographic and demographic specificity of advertisements and
reduces operating costs. The SeaChange Advertising Management Software operates
in conjunction with the SeaChange SPOT System to automate and simplify complex
sales, scheduling and billing processes for the multichannel television market.

     The Company has two existing movie products and one video-on-demand (VOD)
product all for the movie markets. The Company sells the SeaChange Movie System
which provides long-form video storage and delivery for the pay-per-view movie
markets and the SeaChange GuestServe System for delivering video-on-demand and
other guest services, internet access and PC games in a hotel environment for
cable television and telecommunications companies. The Company also sells its
video server, which is designed to store and distribute video streams of various
lengths, and MediaCluster, SeaChange's proprietary software technology that
enables multiple video servers to operate together as an integrated video
server.

     The Company introduced its Broadcast MediaCluster product in 1998, offering
play to air capability for commercials and syndicated or other programming for
broadcast television companies. During 1998, the Company installed broadcast
systems at customer locations including network affiliates in the United States
and broadcast companies internationally.

     Finally, SeaChange has developed the SeaChange ITV (Interactive Television)
MediaCluster to provide residential video-on-demand and other interactive
services for cable television operators and telecommunications companies. During
1998, SeaChange entered into agreements with several cable companies to provide 
SeaChange's ITV System for demonstration and testing of their video-on-demand 
systems. The Company also has agreements with certain developers of digital 
set-top boxes to test and integrate their products with SeaChange's ITV System.

     The Company was incorporated in Delaware in July 1993.

Industry Background

     Television operators, the largest users of professional quality video,
historically have relied on videotape technology such as reel-to-reel technology
and tape cassettes for the storage and distribution of video streams. These
systems, which use video tape as the primary mechanism for the storage and
distribution of video, have substantial limitations. Video tapes and their
associated recording playback mechanisms are subject to mechanical failure and
generational loss of video quality. Tape-based systems also require significant
manual intervention, which makes them expensive and cumbersome to operate and
limits their flexibility for programming and schedule changes. Finally, video
tapes are bulky and have limited storage capacity.

     Over the past decade, the limitations of video tape-based systems have
become increasingly apparent. Changes in government regulation and increased
competition have forced television operators, to seek new revenue sources and
reduce costs. In addition, television operators, to be competitive in the
widening home-entertainment market, must find and offer new and enhanced video
services while simultaneously improving the efficiency of their operations.
While video tape-based systems are sufficient for some traditional applications,
they do not meet the performance and cost requirements of these new, targeted
applications.


     Cable Television Operators & Telecommunications Companies

     According to industry sources, there are approximately 12,000 cable systems
currently in the United States, serving over 70 million households. In 1998, 96%
of all cable systems provided over 30 channels of programming to their
subscribers.  Because cable television programming is sent over broadband lines,
operators can segment and target their programming to viewers in selected
geographies. In addition, the continuing growth in cable television's multiple
specialized programming networks, such as CNN, MTV and ESPN and other networks
such as Black Entertainment Television, the Discovery Channel and Nickelodeon,
allow advertisers to target viewers in selected demographic profiles.

     Despite this advantage over television broadcasters, cable television
operators historically have not realized advertising revenues in proportion to
their share of television viewers. According to industry sources, in 1998, 48%
of all television viewers were watching cable networks, yet cable television
advertising revenue accounted for only 24% of the total television advertising
revenue. In addition, advertising represents the major source of revenue for
television broadcasters, while most cable television operators derive less than
5% of their gross revenue from advertising. The limitations of video tape-based
technology are a major factor which has prevented cable television operators
from historically exploiting their advantages over television broadcasters.
These systems are difficult to manage in multichannel and multi-zone
environments, resulting in relatively poor video insertion accuracy and high
operating costs.
 
     Video-on-demand represents a new opportunity for cable television
operators. Increased channel capacity through the installation of fiber optic
cables is providing many cable television operators with the capacity to offer
video-on-demand to hotel and apartments using existing analog set-top boxes. The
addition of two way connectivity, and digital set-top boxes are providing many
cable television operators with the capacity to offer video-on-demand
programming capability throughout their subscriber base.

                                       3
<PAGE>
 
     The recent deregulation of the United States telecommunications industry
has lowered the legal barriers to entry for telecommunications companies to
enter the multichannel video delivery market. Telecommunications companies are
attempting to capitalize on the new growth opportunities by acquiring existing
cable television operators and by leveraging their existing telephony networks
to establish new multichannel video delivery operations. However,
telecommunications companies face the same limitations as cable television
operators in offering targeted, value-added services with analog tape-based
systems on a cost effective basis.

     Increased demand for video and audio content over the internet will require
a substantial increase in storage capacity and bandwidth over time. The Company
believes that cable television operators and telecommunications companies will
play an integral role in providing these broadband internet applications. The
Company also believes that in order to offer high quality video applications
over the internet, cable television operators and telecommunications companies
will need storage and distribution products capable of complex management and
scheduling of video data streams.


  Television Broadcasters

     The more than 1,500 broadcast stations in the United States, including
network affiliates and independent stations, face many of the same technological
issues as cable television operators. Additionally, television broadcasters rely
on advertising for nearly all of their revenue and require high advertisement
run-rate reliability and image quality. To date, television broadcasters have
utilized tape-based systems with robotic libraries, which are cumbersome and
require high levels of maintenance and manual intervention to ensure that the
needed performance requirements are met. Also, the video tapes in these systems
need to be replaced frequently due to repeated use.

     In addition, many broadcasters are contemplating the use of the recently
available digital bandwidth to originate multiple program streams.  If this
application develops, television operators will require video storage and
delivery systems that can effectively manage and deliver these multiple
television signals.

The SeaChange Solution

     SeaChange develops, markets and supports digital video solutions designed
to enhance its customers' ability to store, retrieve, manage and distribute
short-and long-form video streams, including advertisements, movies, news
updates and other video programming requiring precise, accurate and continuous
execution. The Company's solutions are based on five core areas of
functionality: (i) real-time conversion of analog video into digital video
format; (ii) storage and retrieval of video content to and from digital
libraries; (iii) scheduled distribution of video streams between digital
libraries via local and wide area data networks; (iv) delivery of video streams
over single and multiple channels; and (v) management of video sales,
scheduling, billing and execution of related business transactions.

     SeaChange uses these core capabilities to provide solutions to a number of
commercial markets. The Company's products are designed to provide a consistent
set of features and benefits, including:

     Viewer Targeting. The Company's digital video products enable
     television operators to efficiently target viewers in specific
     demographic or geographic groups. The ability to target selected
     viewers enables television operators to increase revenues by offering
     more targeted services. The SeaChange SPOT System offers this
     capability to television operators, the Broadcast MediaCluster product
     offers this capability to broadcast companies while the SeaChange
     Guestserve and ITV MediaCluster Systems make it possible for television
     operators to offer video-on-demand movies to individual hotel rooms or
     residences.
     
     Cost Reduction. The Company's products are designed to provide its
     customers operating cost reductions as compared to analog tape-based
     systems due to, among other things, the elimination of video tapes and
     their storage and lower operating personnel requirements. The Company
     is also able to price its products on a competitive basis by using
     standard operating systems and components. The Company believes that
     the combination of competitive pricing of its products and reductions
     in the operating costs of its customers results in attractive pay-back
     periods on customers' initial capital outlay for the Company's
     products.
     
     Scalability. The Company's products are scalable to the needs of a
     particular cable television operator or television broadcaster whether
     operating in a single channel system concentrated in one specific zone
     or a system with hundreds of channels serving multiple zones and
     markets. Moreover, the Company's proprietary storage technology enables
     the scalability of storage of digital video from a few minutes to
     hundreds of hours of video.
     
     Reliability. The Company's products eliminate the need for traditional
     mechanical tape-based systems, thereby reducing the likelihood of
     breakdowns. Furthermore, through the use of redundant components and
     proprietary storage technology and application software, SeaChange's
     products are designed to be fault resilient, providing the high
     reliability required for television operations.
     
     Scheduling Flexibility. The digitizing and storage of video streams
     allows advertisements, news updates and movies to be inserted on
     channels in local communities and allows cable television operators to
     insert or delete video content rapidly. This flexibility enables the
     provision of services such as video-on-demand movies and provides
     advertisers and television broadcasters the opportunity to insert new
     video content on short notice.
     
     Video Image Quality. Because digital video streams do not degrade with
     playback, image content and quality remain at the original professional
     level even after multiple airings.
     
     Ease of Use. The Company's products are simple to learn, require less
     maintenance, and are less personnel intensive than analog systems. Due
     to their innovative architecture, the Company's products offer a number
     of features that simplify their use, including remote monitoring and
     service and automated short- and long-form video distribution.

Strategy

     SeaChange's objective is to be the leader in the emerging market for the
storage, management and distribution of professional quality digital video. The
key elements of the Company's strategy are to:

     Develop Long-Term Customer Relationships. The Company is focusing its
     product development, marketing and direct sales efforts on developing long-
     term customer relationships with cable television operators,
     telecommunications companies and television broadcasters in the United
     States and internationally. The Company has formed its customer
     relationships by providing digital video solutions to address customers'
     immediate problems, such as advertisement and other short-form video
     insertion. The Company intends to continue to leverage its customer
     relationships to offer new, compatible products to meet evolving market
     needs, such as video-on-demand programming. The Company believes that the
     fundamental shift from analog to digital video and the growing emphasis on
     interactive technologies will continue to present opportunities for the
     Company to develop, market and support its products to both its existing
     customer base and to customers in additional markets.

     Offer Complete Solutions. SeaChange's customers operate complex networks
     that require the delivery and management of video programming across
     multiple channels and target zones. SeaChange believes television operators
     desire complete solutions that integrate all steps of digital video
     delivery from scheduling to post-air verification and billing. To address
     these needs, SeaChange provides integrated applications and support
     services which are more valuable to customers than individual functional
     products not specifically designed to work together. The Company believes
     that providing complete solutions has been a significant factor in its
     success and will be an increasingly important competitive advantage.

     Establish and Maintain Technological Leadership Through Software. SeaChange
     believes its competitive position is dependent in a large part on the
     features and performance of its application and network and storage
     software. As a result, the Company focuses a majority of its research and
     development efforts on introducing new software applications and improving
     its current software. The Company seeks to use standard hardware components
     wherever possible to maintain its focus on software development.

     Provide Superior Customer Service and Support. The Company's products
     operate in environments where continuous operation is critical. As a
     result, the Company believes that providing a high level of service and
     support gives it a competitive advantage and is a differentiating factor in
     developing key customer relationships. The Company's in-depth industry and
     application knowledge allows it to better understand the service needs of
     its customers. As of December 31, 1998 more than 34% of the Company's
     employees were dedicated to customer service and support, including project
     design and implementation, installation and training. In addition, using
     remote diagnostic and communications features embedded in the Company's
     products, the service organization has the ability to monitor the
     performance of customer installations and, in most cases, rectify problems
     remotely. Customers have access to service personnel via 24-hour, seven-day
     a week telephone support.

Products

     SeaChange develops digital video products and related applications for the
television industry. Its products are marketed to cable television operators,
telecommunication companies, television broadcasters, systems integrators and
VARs.


     SeaChange SPOT System

     The SeaChange SPOT System automates the complex process of advertisement
and other video insertion across multiple channels and geographic zones for
cable television operators and telecommunications companies. Through its
proprietary software, the SeaChange SPOT System allows cable television
operators to insert local and regional advertisements and other short-form video
streams into the time allocated for these video streams by cable television
networks such as CNN, MTV, ESPN, Black Entertainment Television, the Discovery
Channel and Nickelodeon.

     The SeaChange SPOT System is an integrated solution composed of software
applications, hardware platforms, data networks and easy to use graphical
interfaces. The SeaChange SPOT System is designed to be installed at local cable
transmission sites, known as headends, and advertising sales business offices.
The SeaChange video insertion process consists of six steps:

Encoding:        The process begins with the SeaChange Encoding Station, which
                 is based on SeaChange's proprietary encoding software, where
                 analog-based short- and long-form video is digitized and
                 compressed in real-time using standard MPEG-2 hardware.
               
Storage:         Digital video is then stored in a disk-based video library,
                 capable of storing thousands of spots, where the SeaChange
                 SPOT System organizes, manages and stores these video
                 streams.
               
Scheduling:      SeaChange's advertising management software coordinates with
                 the traffic and billing application to determine the designated
                 time slot, channel and geographic zone for each video stream.
               
Distribution:    SeaChange's strategic digital video software then copies the
                 video streams from the master video library and distributes
                 them over the operator's data network to headends, where they
                 are stored in video servers for future play.
               
Insertion:       Following a network cue, the SeaChange video switch module
                 automatically initiates the conversion of video streams to
                 analog and inserts them into the network feed, where they are
                 then seen by television viewers.
               
Verification:    After the video streams run, SeaChange's proprietary software
                 and hardware verifies the content, accuracy, timing and
                 placement of such video streams to facilitate proper customer
                 billing.

 

                                       7

advanced formal on-site training for customer employees at the time of product
installation. The Company currently provides installation, maintenance and
support to international customers and also provides movie content in
conjunction with sales of SeaChange GuestServe System. The Company offers
technical support to customers, agents and distributors on a 24-hour, seven-day
a week basis.


Customers

     The Company currently sells its products primarily to cable television
operators, broadcast and telecommunications companies.

     The Company's customer base is highly concentrated among a limited number
 of large customers, primarily due to the fact that the cable, movie, broadcast,
 and telecommunications industries in the United States are dominated by a
 limited number of large companies. A significant portion of the Company's
 revenues in any given fiscal period have been derived from substantial orders
 placed by these large organizations. In 1996, 1997 and 1998, revenues from the
 Company's five largest customers represented approximately 76%, 68% and 54%,
 respectively, of the Company's total revenues. Customers accounting for more
 than 10% of total revenues consisted of Tele-Communications, Inc. (29%), U.S.
 West Media Group (17%), Comcast Corporation (13%) and Time Warner, Inc. (12%)
 in 1996; Tele-Communications, Inc. (24%), Time Warner, Inc. (18%) and Comcast
 Corporation (10%) in 1997; Tele-Communications, Inc. (24%) and Time Warner,
 Inc. (15%) in 1998. The Company expects that it will continue to be dependent
 upon a limited number of customers for a significant portion of its revenues in
 future periods. As a result of this customer 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 or new product announcements or introductions.

     The Company believes that its backlog at any particular time is not
meaningful as an indicator of its future level of sales for any particular
period. Because of the nature of the Company's products and its use of standard
components, substantially all of the backlog at the end of a quarter can be
manufactured by the Company and is intended to be shipped by the end of the
following quarter. However, because of the requirements of particular customers
and, in respect to certain sales, the acceptance criteria necessary for revenue
recognition, such backlog may not be shipped or, if shipped, the related
revenues may not be recognized in such quarter. Therefore, there is no direct
correlation between the backlog at the end of any quarter and the Company's
total sales for the following quarter or other periods.


Selling and Marketing

     The Company sells and markets its products in the United States primarily
through a direct field sales organization and internationally primarily through
independent agents and distributors, complemented by a coordinated marketing
effort of the Company's marketing group. Direct sales activities in the United
States are conducted from the Company's Massachusetts headquarters and seven
field offices. In October 1996, the Company entered into an exclusive sales and
marketing services agreement with a private Italian company to provide such
services throughout continental Europe. The Company also markets certain of its
products, namely the Video Server 100 and MediaCluster, to systems integrators
and VARs. As of December 31, 1998, the Company's selling and marketing
organization consisted of 32 people.

     In light of the complexity of the Company's digital video products, the
Company primarily employs a consultative direct sales process. Working closely
with customers to understand and define their needs enables the Company to
obtain better information regarding market requirements, enhance its expertise
in its customers' industries, and more effectively and precisely convey to
customers how the Company's solutions address the customer's specific needs. In
addition to the direct sales process, customer references and visits by
potential customers to sites where the Company's products are in place are often
critical in the sales process.

                                       10

     The Company uses several marketing programs focused on the Company's
targeted markets to support the sale and distribution of its products. The
Company uses exhibitions at a limited number of prominent industry trade shows
and conferences and presentations at technology seminars to promote awareness of
the Company and its products. The Company also publishes technical articles in
trade and technical journals and promotional product literature.


Research and Product Development

     Management believes that the Company's success will depend to a substantial
degree upon its ability to develop and introduce in a timely fashion new
products and enhancements to its existing products that meet changing customer
requirements in the Company's current and new markets. The Company has in the
past made, and intends to continue to make, substantial investments in product
and technological development. Through its direct sales process the Company
monitors changing customer needs, changes in the marketplace and emerging
industry standards, and is therefore better able to focus its research and
development efforts to address such evolving industry requirements.

     The Company's research and development expenditures totaled approximately
$5.4 million, $11.8 million and $15.8 million for the years ended December 31,
1996, 1997 and 1998, respectively. At December 31, 1998, 102 employees were
engaged in research and product development. The Company believes that the
experience of its product development personnel is an important factor in the
Company's success. The Company performs its research and product development
activities at its headquarters and in offices in Greenville, New Hampshire,
Atlanta, Georgia and Novato, California. The Company has historically expensed
its direct research and development costs as incurred.

     The Company has a variety of new products being developed and tested,
including interactive television products for cable television operators and
telecommunications companies, digital play-to-air systems for television
broadcasters and the next version of its MediaCluster software. There can be no
assurance that the Company will be able to successfully develop and market such
products, or to identify, develop, manufacture, market or support other new
products or enhancements to its existing products successfully or on a timely
basis, that new Company products will gain market acceptance, or that the
Company will be able to respond effectively to product announcements by
competitors or technological changes.


Acquired In-Process Research and Development

     In 1997, in connection with the acquisition of IPC, $5,290,000 of the
purchase price, based upon an independent appraisal, was allocated to in-process
research and development, resulting in an immediate charge to the Company's
operations as of the date of acquisition. The amount allocated to in-process
research and development represented technology which had not reached
technological feasability and did not have an alternative future use. The
Company was continuing development of the software applications and hardware
design of this in-process development as of December 31, 1998. Management
estimates the development of this in-process development to be completed during
1999 and for some features in 2000.


Manufacturing

     The Company's manufacturing operations are located at facilities in
Maynard, Massachusetts and in Greenville, New Hampshire. The manufacturing
operations in Massachusetts consist primarily of component and subassembly
procurement, system integration and final assembly, testing and quality control
of the complete systems. The Company's operations in New Hampshire consist
primarily of component and subassembly procurement, video server integration and
final assembly, testing and quality control of the video servers. The Company
relies on independent contractors to manufacture components and subassemblies to
the Company's specifications. Each of the Company's products undergoes testing
and quality inspection at the final assembly stage.

                                       11
<PAGE>
 
     The Company attempts to use standard parts and components available from
multiple vendors. Certain components used in the Company's products, however,
are currently purchased from a single source, including a computer chassis
manufactured by Trimm Technologic Inc., a disk controller manufactured by Mylex
Corporation, an MPEG-2 decoder card manufactured by Vela Research, Inc. and an
MPEG-2 encoder manufactured by Optivision, Inc.  While the Company believes that
there are alternative suppliers available for these components, the Company
believes that the procurement of such components from alternative suppliers
would take anywhere from 45-120 days. There can be no assurance that such
alternative components would be functionally equivalent or would be available on
a timely basis or on similar terms. The Company purchases several other
components from a single supplier, although the Company believes that
alternative suppliers for such components are readily available on a timely
basis. The Company generally purchases sole source or other components pursuant
to purchase orders placed from time to time in the ordinary course of business
and has no written agreements or guaranteed supply arrangements with its sole
source suppliers. The Company has experienced quality control problems and
supply shortages for sole source components in the past and there can be no
assurance that the Company will not experience significant quality control
problems or supply shortages for these components in the future. However, any
interruption in the supply of such single source components could have a
material adverse effect on the Company's business, financial condition and
results of operations. Because of the Company's reliance on these vendors, the
Company may also be subject to increases in component costs which could
adversely affect the Company's business, financial condition and results of
operations.


Competition

     The markets in which the Company competes are characterized by intense
competition, with a large number of suppliers providing different types of
products to different segments of the markets. The Company currently competes
principally on the basis of: (i) the breadth of its products' features and
benefits, including the ability to precisely target viewers in specific
geographic or demographic groups, and the flexibility, scalability, professional
quality, ease of use, reliability and cost effectiveness of its products; and
(ii) the Company's reputation and the depth of its expertise, customer service
and support. While the Company believes that it currently competes favorably
overall with respect to these factors and that its ability to provide solutions
to manage, store and distribute digital video differentiates the Company from
its competitors, there can be no assurance that the Company will be able to
continue to compete successfully with respect to such factors.

     In the digital advertisement insertion market, the Company generally
competes only with SkyConnect, Inc. In the market for long-form video products,
the Company competes with various computer companies offering video server
platforms such as Hewlett-Packard Company and Silicon Graphics, Inc., and more
traditional movie application providers like The Ascent Entertainment Group,
Panasonic Company, and Lodgenet Entertainment. In addition, the SeaChange
Advertising Management Software competes against certain products of Columbine
Cable Systems, Inc., Cable Computerized Management Systems, Inc., a subsidiary
of Indenet Inc., CAM Systems, Inc., a subsidiary of Starnet Inc., LAN
International USA, Inc., Visiontel, Inc. and various suppliers of sales,
scheduling and billing software products. In the television broadcast market,
the Company competes against Tektronix, Inc., Hewlett-Packard Company, Sony
Corporation, and ASC Incorporated. The Company expects the competition in each
of these markets to intensify in the future.

                                       12
<PAGE>
 
     Many of the Company's current and prospective competitors have
significantly greater financial, technical, manufacturing, sales, marketing and
other resources than the Company. As a result, these competitors may be able to
devote greater resources to the development, promotion, sale and support of
their products than the Company. Moreover, these companies may introduce
additional products that are competitive with those of the Company or enter into
strategic relationships to offer complete solutions, and there can be no
assurance that the Company's products would compete effectively with such
products.

     Although the Company believes that it has certain technological and other
advantages over its competitors, maintaining such advantages will require
continued investment by the Company in research and development, selling and
marketing and customer service and support. In addition, as the Company enters
new markets, distribution channels, technical requirements and competition
levels may be different than those in the Company's current markets. There can
be no assurance that the Company will be able to compete successfully against
either current or potential competitors in the future.


Proprietary Rights

     The Company's success and its ability to compete is dependent, in part,
upon its proprietary rights. The Company has been granted one U.S. patent for
its MediaCluster technology and has filed a foreign patent application for the
same technology. In addition, the Company has other patent applications in
process for other technologies. In addition, the Company relies on a combination
of contractual rights, trademark laws, trade secrets and copyright laws to
establish and protect its proprietary rights in its products. There can be no
assurance that all of these patents will be issued or that, if issued, the
validity of such patents would be upheld. Nor can there be any assurance that
the steps taken by the Company to protect its intellectual property will be
adequate to prevent misappropriation of its technology or that the Company's
competitors will not independently develop technologies that are substantially
equivalent or superior to the Company's technology. In addition, the laws of
some foreign countries in which the Company's products are or may be distributed
do not protect the Company's proprietary rights to the same extent as do the
laws of the United States.

      The Company is also subject to the risk of adverse claims and litigation
alleging infringement of intellectual property rights of others. The Company
attempts to ensure that its products do not infringe any existing proprietary
rights of others.

      A version of the SeaChange Advertising and Management Software in limited
distribution was based on software the Company licensed from Summit Software
Systems, Inc. of Boulder, Colorado in May 1996. The Company has been granted a
perpetual, nonexclusive license to such software in return for the payment of an
up-front license fee and royalties for sales occurring prior to June 1998.


Employees

     As of December 31, 1998, the Company employed 310 persons, including 102 in
research and development, 107 in customer service and support, 32 in selling and
marketing, 42 in manufacturing and 27 in finance and administration. One of the
Company's employees is represented by a collective bargaining arrangement. The
Company believes that its relations with its employees are good.


                             CERTAIN RISK FACTORS
                                        
     Limited Operating History and Operating Results. The Company was founded in
July 1993 and commenced shipment of its initial products in the third quarter of
1994. Accordingly, the Company has only a limited operating

                                       13
<PAGE>
 
history upon which an evaluation of the Company and its prospects can be based.
The Company's prospects must be considered in light of the risks, expenses and
difficulties frequently encountered by companies in their early stage of
development, particularly companies in new and rapidly evolving markets. To
address these risks, the Company must, among other things, respond to
competitive developments, continue to attract, retain and motivate qualified
persons, and continue to upgrade its technologies and commercialize products and
services incorporating such technologies. There can be no assurance that the
Company will be successful in addressing such risks.

     Fluctuations in Quarterly Operating Results.   The Company's quarterly
operating results have in the past varied and in the future will be affected by
factors such as: (i) the timing and recognition of revenue from significant
orders, (ii) the seasonality of the placement of customer orders, (iii) the
success of the Company's products, (iv) increased competition, (v) changes in
the Company's pricing policies or those of its competitors, (vi) the financial
stability of major customers, (vii) new product introductions or enhancements by
competitors, (viii) delays in the introduction of products or product
enhancements by the Company, (ix) customer order deferrals in anticipation of
upgrades and new products, (x) the ability to access a sufficient supply of sole
source and third party components, (xi) the quality and market acceptance of new
products, (xii) the timing and nature of selling and marketing expenses (such as
trade shows and other promotions), (xiii) personnel changes, (xiv) the risks
associated with international sales as the Company expands its markets, and (xv)
economic conditions affecting the Company's customers. Any significant
cancellation or deferral of purchases of the Company's products could have a
material adverse effect on the Company's business, financial condition and
results of operations in any particular quarter, and to the extent significant
sales occur earlier than expected, operating results for subsequent quarters may
be adversely affected. The Company's expense levels are based, in part, on its
expectations as to future revenues, and the Company may be unable to adjust
spending in a timely manner to compensate for any revenue shortfall. If revenues
are below expectations, operating results are likely to be adversely affected
and net income may be disproportionately affected because a significant portion
of the Company's expenses do not vary with revenues.

     Because of these factors, the Company believes that period-to-period
comparisons of its results of operations are not necessarily meaningful and
should not be relied upon as indications of future performance. Due to all of
the foregoing factors, in some future quarter the Company's operating results
may be below the expectations of public market analysts and investors.

     Seasonality.   The Company has experienced significant variations in the
revenue, expenses and operating results from quarter to quarter and such
variations are likely to continue. The Company believes that fluctuations in the
number of orders being placed from quarter to quarter is principally
attributable to the buying patterns and budgeting cycles of television operators
and broadcast companies, the primary buyers of the digital advertising systems
and broadcast systems, respectively. The Company expects that there will
continue to be fluctuations in the number and value of orders received. As a
result, the Company's results of operations have in the past and likely will, at
least in the near future, fluctuate in accordance with such purchasing activity.
Operating expenses also vary with the number, timing and significance of new
product and product enhancement introductions by the Company and its
competitors, increased competition, the gain or loss of significant customers,
the hiring of new personnel and general economic conditions. All of the above
factors are difficult for the Company to forecast, and these or other factors
may materially adversely affect the Company's business, financial condition and
results of operations for one quarter or a series of quarters. Only a small
portion of the Company's expenses vary with revenues in the short-term and there
would likely be a material adverse effect on the operating results of the
Company if future revenues are lower than expectations.

     Management of Growth.   The Company has experienced fluctuation in revenues
and expansion of its operations which have placed significant demands on the
Company's management, administrative and operational resources. The Company
believes that further improvements in management and operational controls are
needed, and would continue to be needed to manage any future growth. Continued
growth will also require the Company to hire more customer sevice and
administrative personnel, expand manufacturing and customer service
capabilities, and update or expand management information systems. There can be
no assurance that the Company will be able to attract and retain the necessary
personnel to accomplish its growth strategies or that it will not experience

                                       14
<PAGE>
 
constraints that will adversely affect its ability to satisfy customer demand in
a timely fashion or to satisfactorily support its customers and operations.
Also, the Company may in the future acquire complementary service or product
lines, technologies or businesses, although the Company has no present
understandings, commitments or agreements with respect to any significant
acquisitions. If the Company's management is unable to manage growth effectively
or integrate any acquisition into the Company's operations successfully, the
Company's business, financial condition and results of operations could be
materially and adversely affected.

     Product Concentration. Sales of the SeaChange SPOT System have historically
accounted for a large percentage of the Company's revenues, and this product and
related enhancements are expected to continue to account for a significant
portion of the Company's revenues in 1999. The Company's success depends in part
on continued sales of the SeaChange SPOT System. A decline in demand or average
selling prices for the SeaChange SPOT System product line, whether as a result
of new product introductions by others, price competition, technological change,
inability to enhance the products in a timely fashion, or otherwise, would have
a material adverse effect on the Company's business, financial condition and
results of operations.

     Highly Competitive Markets.   The market for digital video, movie and
broadcast products is highly competitive. The Company currently competes against
suppliers of both analog tape-based and digital systems in the digital
advertisement insertion market and against both computer companies offering
video server platforms and more traditional movie application providers in the
movie system market. In the television broadcast market, the Company competes
against various computer companies offering video server platforms and
television equipment manufacturers. Due to the rapidly evolving markets in which
the Company competes, additional competitors with significant market presence
and financial resources, including computer hardware and software companies and
television equipment manufacturers, may enter those markets, thereby further
intensifying competition. Increased competition could result in price reductions
and loss of market share which would adversely affect the Company's business,
financial condition and results of operations. Many of the Company's current and
potential competitors have greater financial, selling and marketing, technical
and other resources than the Company. Moreover, the Company's competitors may
also foresee the course of market developments more accurately than the Company.
Although the Company believes it has certain technological and other advantages
over its competitors, realizing and maintaining such advantages will require a
continued high level of investment by the Company in research and product
development, marketing and customer service and support. There can be no
assurance that the Company will have sufficient resources to continue to make
such investments or that the Company will be able to make the technological
advances necessary to compete successfully with its existing competitors or with
new competitors.

     Dependence on Emerging Digital Video Market. Cable television operators and
television broadcasters have historically relied on traditional analog
technology for video management, storage and distribution. Digital video
technology is still a relatively new technology and requires a significant
initial investment of capital. The Company's future growth will depend both on
the rate at which television operators convert to digital video systems and the
rate at which digital video technology expands to additional market segments.
There can be no assurance that the use of digital video technology will expand
among television operators or into additional markets. Any failure by the market
to accept digital video technology will have a material adverse effect on the
Company's business, financial condition and results of operations.

     Risks Associated with Expansion into New Markets.   To date the Company's
products have been purchased primarily by cable television operators and
telecommunications companies. The Company's success depends in part on the
penetration of new markets. In particular, the Company introduced broadcast
products during the quarter ended June 30, 1998  for use by television
broadcasters. These broadcast products will be directed toward a market that the
Company has not significantly addressed. There can be no assurance that the
Company will be successful in marketing and selling broadcast products to
customers in the broadcast television market. Any inability of the Company to
penetrate this new market would have a material adverse effect on the Company's
business, financial condition and results of operations.

                                       15
<PAGE>
 
     Risk of New Product Introductions.   The Company's future success requires
that it develop and market additional products that achieve significant market
acceptance and enhance its current products. The Company has recently introduced
its Guestserve and Broadcast MediaCluster Products and is developing its ITV
MediaCluster product for introduction.   There can be no assurance that the
Company will not experience difficulties that could delay or prevent the
successful development, introduction and marketing of these and other new
products and enhancements, or that its new products and enhancements will
adequately meet the requirements of the marketplace and achieve market
acceptance. Announcements of currently planned or other new product offerings
may cause customers to defer purchasing existing Company products. Moreover,
there can be no assurance that, despite testing by the Company, and by current
and potential customers, errors or failures will not be found in the Company's
products, or, if discovered, successfully corrected in a timely manner. Such
errors or failures could cause delays in product introductions and shipments, or
require design modifications that could adversely affect the Company's
competitive position. The Company's inability to develop on a timely basis new
products, enhancements to existing products or error corrections, or the failure
of such new products or enhancements to achieve market acceptance could have a
material adverse effect on the Company's business, financial condition and
results of operations.

     Rapid Technological Change.   The markets for the Company's products are
characterized by rapidly changing technology, evolving industry standards and
frequent new product introductions and enhancements. Future technological
advances in the television and video industries may result in the availability
of new products or services that could compete with the solutions provided by
the Company or reduce the cost of existing products or services, any of which
could enable the Company's existing or potential customers to fulfill their
video needs better and more cost efficiently than with the Company's products.
The Company's future success will depend on its ability to enhance its existing
digital video products, including the development of new applications for its
technology and to develop and introduce new products to meet and adapt to
changing customer requirements and emerging technologies. There can be no
assurance that the Company will be successful in enhancing its digital video
products or developing, manufacturing and marketing new products which satisfy
customer needs or achieve market acceptance. In addition, there can be no
assurance that services, products or technologies developed by others will not
render the Company's products or technologies uncompetitive, unmarketable or
obsolete, or that announcements of currently planned or other new product
offerings by either the Company or its competitors will not cause customers to
defer or fail to purchase existing Company solutions. The failure of the Company
to respond to rapidly changing technologies related to digital video could have
a material adverse effect on the Company's business, financial condition and
results of operations.

     Significant Concentration of Customers.   The Company's customer base is
highly concentrated among a limited number of large customers, and, therefore, a
limited number of customers account for a significant percentage of the
Company's revenues in any year. In 1996, 1997 and 1998, revenues from the
Company's five largest customers represented approximately 76%, 68% and 54%,
respectively, of the Company's total revenues. In 1996, 1997 and 1998 four,
three and two customers, respectively, each accounted for more than 10% of the
Company's revenues.  The same two customers accounted for more than 10% of the
Company's revenues in each 1996, 1997 and 1998. The Company generally does not
have written continuing purchase agreements with its customers and does not have
any written agreements that require customers to purchase fixed minimum
quantities of the Company's products. The Company's sales to specific customers
tend to vary significantly from year to year depending upon such customers'
budgets for capital expenditures and new product introductions. In addition, the
Company derives a substantial portion of its revenues from products that have a
selling price in excess of $200,000. The Company believes that revenue derived
from current and future large customers will continue to represent a significant
proportion of its total revenues. The loss of, or reduced demand for products or
related services from, any of the Company's major customers could have a
material adverse effect on the Company's business, financial condition and
results of operations.

     Dependence on Sole Source Suppliers and Third Party Manufacturers. Certain
key components of the Company's products are currently purchased from a sole
supplier, including a computer chassis manufactured by Trimm Technologic Inc., a
disk controller manufactured by Mylex Corporation, an MPEG-2 decoder card
manufactured by Vela Research, Inc. and an MPEG-2 encoder manufactured by

                                       16
<PAGE>
 
Optivision, Inc. The Company has in the past experienced quality control
problems, where products did not meet specifications or were damaged in
shipping, and delays in the receipt of such components. These problems were
generally of short duration and did not have a material adverse effect on the
Company. However, the Company may in the future experience similar types of
problems which could be more severe or more prolonged. The inability to obtain
sufficient key components as required, or to develop alternative sources if and
as required in the future, could result in delays or reductions in product
shipments which, in turn, could have a material adverse effect on the Company's
business, financial condition and results of operations. Moreover, the Company
relies on a limited number of third parties who manufacture certain components
used in the Company's products. While to date there has been suitable third
party manufacturing capacity readily available at acceptable quality levels,
there can be no assurance that such manufacturers will be able to meet the
Company's future volume or quality requirements or that such services will
continue to be available to the Company at favorable prices. Any financial,
operational, production or quality assurance difficulties experienced by such
third party manufacturers that result in a reduction or interruption in supply
to the Company could have a material adverse effect on the Company's business,
financial condition and results of operations.

     Regulation of Telecommunications and Television Industries.   The
telecommunications and television industries are subject to extensive regulation
in the United States and other countries. The Company's business is dependent
upon the continued growth of such industries in the United States and
internationally. Although recent legislation has lowered the legal barriers to
entry for telecommunications companies into the United States multichannel
television market, there can be no assurance that such telecommunications
companies will successfully enter this or related markets. Moreover, the growth
of the Company's business internationally is dependent in part on similar
deregulation of the telecommunications industry abroad and there can be no
assurance that such deregulation will occur. Television operators are also
subject to extensive government regulation by the Federal Communications
Commission ("FCC") and other federal and state regulatory agencies. These
regulations could have the effect of limiting capital expenditures by television
operators and thus could have a material adverse effect on the Company's
business, financial condition and results of operations. The enactment by
federal, state or international governments of new laws or regulations, changes
in the interpretation of existing regulations or a reversal of the trend toward
deregulation in these industries could adversely affect the Company's customers,
and thereby materially adversely affect the Company's business, financial
condition and results of operations.

     Lengthy Sales Cycle.   Digital video, movie and broadcast products are
relatively complex and their purchase generally involves a significant
commitment of capital, with attendant delays frequently associated with large
capital expenditures and implementation procedures within an organization.
Moreover, the purchase of such products typically requires coordination and
agreement among a potential customer's corporate headquarters and its regional
and local operations. For these and other reasons, the sales cycle associated
with the purchase of the Company's digital video, movie and broadcast products
are typically lengthy and subject to a number of significant risks, including
customers' budgetary constraints and internal acceptance reviews, over which the
Company has little or no control. Based upon all of the foregoing, the Company
believes that the Company's quarterly revenues, expenses and operating results
are likely to vary significantly in the future, that period-to-period
comparisons of its results of operations are not necessarily meaningful and
that, in any event, such comparisons should not be relied upon as indications of
future performance.

     Dependence on Key Personnel and Hiring of Additional Personnel.   The
Company's success depends to a significant degree upon the continued
contributions of its key management, engineering, selling and marketing and
manufacturing personnel, many of whom would be difficult to replace. The Company
does not have employment contracts with its key personnel. The Company believes
its future success will also depend in large part upon its ability to attract
and retain highly skilled managerial, engineering, selling and marketing,
finance and manufacturing personnel. Competition for such personnel is intense,
and there can be no assurance that the Company will be successful in attracting
and retaining such personnel. The loss of the services of any of the key
personnel, the inability to attract or retain qualified personnel in the future
or delays in hiring required personnel, particularly software engineers and
sales personnel, could have a material adverse effect on the Company's business,
financial condition and results of operations.

                                       17
<PAGE>
 
     Dependence on Proprietary Rights.   The Company's success and its ability
to compete is dependent, in part, upon its proprietary rights. The Company
relies primarily on a combination of patent, copyright, trademark and trade
secret laws, as well as confidentiality procedures and contractual provisions to
protect its proprietary rights. There can be no assurance that such measures
will be adequate to protect the Company's proprietary rights. The Company
attempts to ensure that its products and technology do not infringe the
proprietary rights of third parties. However, there can be no assurance that
third parties will not assert infringement claims against the Company in the
future or that any such claims will not be successful.

     Risks Associated with International Sales.   International sales accounted
for approximately 5%, 12% and 13% of the Company's revenues in 1996, 1997 and
1998, respectively. The Company expects that international sales will account
for a significant portion of the Company's business in the future. However,
there can be no assurance that the Company will be able to maintain or increase
international sales of its products. International sales are subject to a
variety of risks, including difficulties in establishing and managing
international distribution channels, in servicing and supporting overseas
products and in translating products into foreign languages. International
operations are subject to difficulties in collecting accounts receivable,
staffing and managing personnel and enforcing intellectual property rights.
Other factors that can also adversely affect international operations include
fluctuations in the value of foreign currencies and currency exchange rates,
changes in import/export duties and quotas, introduction of tariff or non-tariff
barriers and economic or political changes in international markets.

     Concentration of Ownership.   The Company's officers, directors and their
affiliated entities, and other holders of 5% or more of the Company's
outstanding capital stock, together beneficially owned approximately 58.9% of 
the outstanding shares of Common Stock of the Company as of March 5, 1999. As a
result, such persons will have the ability to elect the Company's directors and
to determine the outcome of corporate actions requiring stockholder approval,
irrespective of how other stockholders of the Company may vote. This
concentration of ownership may have the effect of delaying or preventing a
change in control of the Company which may be favored by a majority of the
remaining stockholders, or cause a change of control not favored by the
Company's other stockholders.

     Year 2000 Issue.   Although the Company does not expect that the Year 2000
issue will have a material effect on the Company's results of operations or
financial condition, the Company is potentially exposed to Year 2000 issues with
respect to internal software and external product offerings. If the Company's
internal systems or its products fail to operate properly as a result of Year
2000, the Company's results of operations and financial condition will be
materially and adversely impacted. The Company continues to evaluate the Year
2000 issue. For a discussion of the Company's Year 2000 readiness and risks
associated with the Year 2000 issue, see "Year 2000 Issue/Readiness Disclosure
Statement," particularly the subsection headed "Risks Associated with Year 2000
Issue" which appears in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" section of this Report on Form 10-K.

ITEM 7.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations.

     The following discussion and analysis should be read in conjunction with
the Company's Consolidated Financial Statements and the related Notes included
elsewhere in this Annual Report on Form 10-K. The following discussion contains
certain trend analysis and other statements of a forward-looking nature relating
to future events or the future financial performance of the Company. Readers are
cautioned that such statements are only predictions and that actual results or
events may differ materially. In evaluating such statements, readers should
specifically consider the risk factors set forth in this Annual Report on Form
10-K, particularly the matters set forth under the caption ''Certain Risk
Factors,'' in Item 1 "Business", which could cause actual results to differ
materially from those indicated by such forward-looking statements.

                                       21

Overview

     The Company develops, markets, licenses and sells digital advertising
insertion, movie and broadcast systems and related services and movie content to
television operators, telecommunications companies, the hospitality and
commercial property markets and broadcast television companies.  Revenues from
systems sales are recognized upon shipment provided that there are no
uncertainties regarding customer acceptance and collection of the related
receivables is probable.  If such uncertainties exist, such as performance
criteria beyond the Company's standard terms and conditions, revenue is
recognized upon customer acceptance.  Installation and training revenue is
deferred and recognized as these services are performed.  Revenue from technical
support and maintenance contracts is deferred and recognized ratably over the
period of the related agreements, generally twelve months.  Customers are billed
for installation, training and maintenance at the time of the product sale.
Revenue from content fees, primarily movies, is recognized in the period earned
based on noncancelable agreements.

     The Company has experienced fluctuations in the number of orders being
placed from quarter to quarter. The Company believes this is principally
attributable to the buying patterns and budgeting cycles of television operators
and broadcast companies, the primary buyers of digital advertising insertion
systems and broadcast systems, respectively. The Company expects that there will
continue to be fluctuations in the number and value of orders received and that
at least in the near future, the Company's revenue and results of operations
will reflect these fluctuations.

     The Company's results are significantly influenced by a number of factors,
including the Company's pricing, the costs of materials used in the Company's
products and the expansion of the Company's operations.  The Company prices its
products and services based upon its costs as well as in consideration of the
prices of competitive products and services in the marketplace.  The costs of
the Company's products primarily consist of the costs of components and
subassemblies that have generally declined over time. As a result of the growth
of the Company's business, operating expenses of the Company have increased in
the areas of research and development, selling and marketing, customer service
and support and administration.

     On December 10, 1997, the Company acquired all of the outstanding capital
stock of IPC Interactive Pte. Ltd. ("IPC") which was renamed to SeaChange Asia
Pacific Operations Pte. Ltd. ("SC Asia"). SC Asia provides interactive
television network systems to the hospitality and commercial property markets.
The transaction was accounted for under the purchase method and, accordingly,
the results of operations of the Company include the operating results of SC
Asia from the date of acquisition.


Results of Operations

     The following table sets forth for the periods indicated the percentage of
total revenues represented by certain items reflected in the Company's
Consolidated Statement of Operations. Gross profit shown for systems and
services revenues at the bottom of the table is stated as a percentage of
related revenues.

Years ended December 31, 1996, 1997 and 1998

     Revenues

     Systems.  The Company's systems revenues consist of sales of its digital
video insertion, movie and broadcast system products.  Systems revenues
increased 32% from $45.7 million in 1996 to $60.4 million in 1997, and decreased
4% to $58.0 million in 1998.  The increased systems revenues in 1997 compared to
1996 resulted from the increase in the number of the Company's digital video
insertion systems sold to television operators primarily in the United States
and the sale of approximately $4.4 million of movie systems compared to $232,000
in 1996.  The decreased systems revenues in 1998 compared to 1997 resulted from
a decrease of approximately $11.9 million in digital advertising insertion
systems revenues, offset by an increase of $5.3 million in movie systems
revenues and an increase $4.2 million in broadcast systems revenues. The
decrease in digital advertising insertion systems revenues is primarily
attributable to a decrease in the volume of digital video insertion systems sold
due to a shift in spending by U.S. cable operators on these products. U.S. cable
operators have shifted their spending patterns to buy expansions to existing
systems and to buy smaller scale digital ad insertion systems. The increase in
1998 of movie systems revenues of approximately $5.3 million is primarily
attributable to an increase in the volume of movie systems sold as a result of
the acquisition of SC Asia. The increase in 1998 of approximately $4.2 million
in broadcast systems is attributable to the initial introduction of the product
during the quarter ended June 30, 1998. The Company expects future systems
revenue growth, if any, to come principally from its broadcast products.

                                       23

     For the years ended December 31, 1996, 1997 and 1998, certain customers
accounted for more than 10% of the Company's total revenues.  Individual
customers accounted for 29%, 17%, 13% and 12% of total revenues in 1996; 24%,
18% and 10% of total revenues in 1997; and 24% and 15% of total revenues in
1998.  The Company believes that revenues from current and future large
customers will continue to represent a significant proportion of total revenues.
 
     International sales accounted for approximately 5%, 12% and 13% of total
revenues in the years ended December 31, 1996, 1997 and 1998, respectively.  The
Company expects that international sales will continue to increase as a
percentage of the Company's business in the future. As of December 31, 1998, all
sales of the Company's products were made in United States dollars.  The Company
does not expect to change this practice in the foreseeable future.  Therefore,
the Company has not experienced, nor does it expect to experience in the near
term, any material impact from fluctuations in foreign currency exchange rates
on its results of operations or liquidity.  If this practice changes in the
future, the Company will reevaluate its foreign currency exchange rate risk.

     Services.  The Company's services revenues consist of fees for
installation, training, product maintenance, technical support services and
movie content fees.  The Company's services revenues increased 112% from
approximately $3.5 million in 1996 to $7.5 million in 1997, and increased 84% to
$13.7 million in 1998.  These increases in services revenues primarily resulted
from the increase in product sales and renewals of maintenance and support
contracts related to the growing installed base of systems and additional
service revenues in the form of movie content fees as a result of the
acquisition of SC Asia.

     Gross Profit

     Systems.  Costs of systems revenues consist primarily of the cost of
purchased components and subassemblies, labor and overhead relating to the final
assembly and testing of complete systems and related expenses.  Costs of systems
revenues increased 28% from $27.1 million in 1996 to $34.7 million in 1997, and
increased 3% to $35.8 million in 1998.  In 1996 and 1997, the increases in costs
of systems revenues primarily reflect the overall growth in systems sales,
partially offset by the change in product mix upon the introduction of the
second generation video insertion product in January 1996 and the decreasing
costs of various components.  In 1998, the increases in costs of systems
revenues reflect increased manufacturing labor and overhead costs incurred to
support changes in the product mix, including the introduction of the broadcast
products.

     Systems gross profit as a percentage of systems revenues was 40.7%, 42.5%
and 38.4% in 1996, 1997 and 1998, respectively.  The increase in systems gross
profit in 1997 in digital advertising insertion systems resulted from lower
costs of certain purchased components and subassemblies for systems, the Company
achieving certain manufacturing efficiencies as a result of increased volume of
systems and design improvements in the second generation video insertion
product.  The increase in systems gross profit in movie systems is attributable
to Company manufacturing and selling a greater number of movie systems, thereby
achieving certain manufacturing efficiencies as a result of increased volume of
systems.  The decrease in systems gross profit in 1998 is attributable to a
shift in the mix of system sales and higher manufacturing labor and overhead
costs. The decrease in gross profit of digital advertising insertion systems is
primarily attributable to revenues including a greater percentage of smaller
scale digital ad insertion systems and expansions to existing systems which have
higher costs on certain purchased components and the overall higher
manufacturing labor and overhead costs. The decrease in gross profit of movie
systems is primarily attributable to higher costs on certain purchased
components, specifically set-top boxes, and overall higher manufacturing labor
and overhead costs. The gross profit of the broadcast products, introduced in
1998, offset the decreases in the gross profit of the movie and digital
advertising insertion systems products. The gross profits in 1996, 1997 and 1998
were impacted by increases of approximately $694,000, $1.7 million and $2.0
million, respectively, in the Company's inventory valuation allowance. The
Company evaluates inventory levels and expected usage on a periodic basis and
provides a valuation allowance for estimated inactive, obsolete and surplus
inventory.

     Services.  Costs of services revenues consist primarily of labor, materials
and overhead relating to the installation, training, product maintenance and
technical support services provided by the Company and costs associated with
providing movie content.  Costs of services revenues increased 89% from

                                       24
<PAGE>
 
approximately $4.0 million in 1996 to $7.6 million in 1997, and increased 74% to
$13.2 million in 1998, primarily as a result of the costs associated with the
Company hiring and training additional service personnel to provide worldwide
support for the growing installed base of digital ad insertion, movie and
broadcast systems and costs associated with providing movie content.  Costs of
services exceeded services revenues by 14.5% and 1.8% in 1996 and 1997,
respectively.  Services gross profit as a percentage of services revenue was
3.6% in 1998.  Improvements in the services gross profit in 1997 and 1998,
reflects the increases in the installed base of systems under service contracts.
Also, the services gross profit in 1998 includes gross profit generated from the
movie content fees as a result of the acquisition of SC Asia. The Company
expects that it will continue to experience fluctuations in gross profit as a
percentage of services revenue as a result of the timing of revenues from
product and maintenance support and other services to support the growing
installed base of systems and the timing of costs associated with the Company's
ongoing investment required to build a service organization to support the
installed base of systems and new products.

     Research and Development. Research and development expenses consist
primarily of compensation of development personnel, depreciation of equipment
and an allocation of related facilities expenses. Research and development
expenses increased 118% from approximately $5.4 million in 1996 to $11.8 million
in 1997, and increased 34% to $15.8 million in 1998. The increases in the dollar
amounts in 1997 and 1998 were primarily attributable to the hiring and
contracting of additional development personnel which reflects the Company's
continuing investment in new products and in 1998, the additional resources
acquired with IPC. All internal software development costs to date have been
expensed by the Company. The Company expects that research and development
expenses will continue to increase in dollar amount as the Company continues its
development and support of new and existing products.

     Selling and Marketing.  Selling and marketing expenses consist primarily of
compensation expenses, including sales commissions, travel expenses and certain
promotional expenses.  Selling and marketing expenses increased 42% from
approximately $4.3 million in 1996 to $6.0 million in 1997, and increased 36% to
$8.2 million in 1998.  The increases in the dollar amounts were attributable to
the hiring of additional selling and marketing personnel, increased
international selling efforts and expanded promotional activities to support the
movie and broadcast products. In 1997, selling expenses were also higher due to
an increase in commission expenses relating to the higher revenue levels.

     General and Administrative.  General and administrative expenses consist
primarily of compensation of executive, finance, human resource and
administrative personnel, legal and accounting services and an allocation of
related facilities expenses.  General and administrative expenses increased 81%
from $2.1 million in 1996 to approximately $3.7 million in 1997, and increased
55% to approximately $5.8 million in 1998.  The increases in the dollar amounts
were primarily attributable to increased staffing and related costs to support
the Company's expanded operations and the acquisition of SC Asia.   The Company
does not expect that general and administrative expenses will increase in dollar
amount in the foreseeable future.

     Write-off of Acquired In-Process Research and Development. In connection
with the acquisition of IPC, the Company acquired certain technology that can be
used with the Company's video server technology to provide interactive
television network systems to the hospitality and commercial property markets.
As discussed in Note 5 to the consolidated financial statements, the Company
recorded a charge to operations of $5,290,000 for the write-off of in-process
research and development, the value of which was determined based upon an
independent appraisal. In addition, the Company recorded intangible assets of
$1,635,000 that included approximately $850,000 of software. Of the acquired
technology, the capitalized amount reflects the allocation of the purchase price
to the software technology deemed technologically feasible, including the
operating system and software for the distribution of movies over the network.
Acquired technology, including software to provide certain new interactive
features and functions over the network, included in the in-process write-off
reflects the purchase price allocated to technology currently under development
and not considered technologically feasible at the time of the acquisition and
with no alternative future use. The Company was continuing the development of
the software applications and hardware design of this in-process development as
of December 31, 1998. Management estimates the development of this in-process
development to be completed during 1999 and for some features in 2000.

                                       25

     Restructuring of Operations.  In March 1998, the Company recorded a charge
of  $676,000 for the restructuring of operations as part of a planned
consolidation of the operations of SC Asia. The charge for restructuring
included $569,000 related to the termination of 13 employees, a provision of
$60,000 related to the planned vacating of premises and $47,000 of compensation
expense associated with stock options for certain terminated employees.  At
March 31, 1998, the Company had notified all terminated employees.  All
restructuring charges were paid as of December 31, 1998.

     Interest Income.  Interest income was approximately $353,000, $657,000 and
$262,000 in 1996, 1997 and 1998, respectively.  The increase in 1997 in interest
income primarily resulted from interest earned on a higher invested balance
primarily due to the net proceeds of $24.1 million from the initial public
offering of the Company's Common Stock in November 1996.  The decrease in
interest income in 1998 primarily resulted from lower average invested balances
in 1998.

     Provision for Income Taxes.  The Company's effective tax rate was 36.8% in
1996. The Company's effective tax rate for 1997 was significantly impacted by
the write-off of the acquired in-process research and development which due to
the tax-free nature of the transaction to IPC stockholders, is not deductible
for tax purposes by the Company.  Accordingly, in 1997 the Company recorded a
tax provision of approximately $1.8 million despite a book pre-tax operating
loss.  The Company's effective tax benefit rate was 37.2% in 1998 due to the
taxable loss in 1998.

     The Company had net deferred tax assets of $1,091,000 and $1,967,000 at
December 31, 1997 and 1998, respectively. The Company has made the determination
it is more likely than not that it will realize the benefits of the net deferred
tax assets. As a result of the acquisition of IPC, the Company acquired deferred
tax assets of $3.4 million, consisting primarily of net operating loss
carryforwards. As discussed in Note 7 of the consolidated financial statements,
the Company maintains a valuation allowance on the acquired net deferred tax
assets.

Quarterly Results of Operations

     The following table presents certain unaudited quarterly information for
the eight quarters ended December 31, 1998. Gross profit shown for systems and
services revenues at the bottom of the table is stated as a percentage of
related revenues. This information is derived from unaudited financial
statements and has been prepared on the same basis as the Company's audited
financial statements which appear elsewhere in this Annual Report. In the
opinion of the Company's management, this data reflects all adjustments
(consisting only of normal recurring adjustments) necessary for a fair
presentation of the information when read in conjunction with the Company's
Consolidated Financial Statements and Notes thereto. The results for any quarter
are not necessarily indicative of future quarterly results, and the Company
believes that period-to-period comparisons should not be relied upon as an
indication of future performance.

</TABLE> 


     The Company has experienced significant variations in revenues, expenses
and operating results from quarter to quarter and such variations are likely to
continue. A significant portion of the Company's revenues have been generated
from a limited number of customers and it is difficult to predict the timing of
future orders and shipments to these and other customers. Customers can cancel
or reschedule shipments, and development or production difficulties could delay
shipments.

     The Company has also experienced significant variations in its quarterly
systems gross margins.  Changes in pricing policies, the product mix, the timing
and significance of new product introductions and product enhancements, and
fluctuations in the number of systems so affects manufacturing efficiencies
and, accordingly, the gross profits.  Quarterly services gross margins have
historically fluctuated significantly because installation and training service
revenue varies by quarter while the related costs are relatively consistent by
quarter.                                  

                                       27
<PAGE>
 
     Operating expenses also vary with the number, timing and significance of
new product and product enhancement introductions by the Company and its
competitors, increased competition, the gain or loss of significant customers,
the hiring of new personnel and general economic conditions. All of the above
factors are difficult for the Company to forecast, and these or other factors
may materially adversely effect the Company's business, financial condition and
results of operations for one quarter or a series of quarters. Only a small
portion of the Company's expenses vary with revenues in the short-term and there
would likely be a material adverse effect on the operating results of the
Company if future revenues are lower than expectations.

     Based upon all of the foregoing, the Company believes that quarterly
revenues and operating results are likely to vary significantly in the future
and that period-to-period comparisons of its results of operations are not
necessarily meaningful and, therefore, should not be relied upon as indications
of future performance.
                                          
Liquidity and Capital Resources           
                                          
     From inception through November 1996, the Company funded its operations
primarily through cash provided by operations and the private sale of equity
securities. In November 1996, in connection with the initial public offering of
the Company's Common Stock, the Company received net proceeds of $24.1 million.
                                          
     Cash, cash equivalents and marketable securities decreased $7.2 million
from $12.3 million at December 31, 1997 to $5.1 million at December 31, 1998.
Working capital decreased from approximately $24.5 million at December 31, 1997
to approximately $22.3 million at December 31, 1998.

     Net cash used in operating activities was approximately $1.9 million, $9.2
million and $7.5 million for the years ended December 31, 1996, 1997 and 1998,
respectively. The net cash used in operating activities during 1998 was the
result of the net loss adjusted for noncash expenses including depreciation and
amortization, deferred income taxes, inventory valuation allowance and the
changes in certain assets and liabilities. The significant net changes in assets
and liabilities that used cash in operations include increases in accounts
receivable, inventories and income taxes receivable.  The net increase in
accounts receivable in 1998 of approximately $6.4 million is attributable to the
increase in revenues in the fourth quarter of 1998 compared to the same period
in 1997. The net increase in inventories in 1998 of approximately $2.4 million
is principally attributable to the increase in the number of product lines.
Income taxes receivable is attributable to the Company carrying back the taxable
loss in 1998 that results in a refund of income taxes.

     Net cash used in investing activities was approximately $3.2 million and
$10.8 million for the years ended December 31, 1996 and 1997, respectively.  Net
cash provided by investing activities was approximately $5.5 million in the year
ended December 31, 1998. Investment activity consisted primarily of capital
expenditures related to the acquisition of computer equipment, office furniture,
and other capital equipment required to support the expansion and growth of the
business.

     Net cash provided by financing activities was approximately $22.3 million
and $4.1 million for the years ended December 31, 1996 and 1998, respectively.
Net cash used in financing activities was approximately $454,000 in the year
ended December 31, 1997. In 1996, the cash provided by financing activities
consisted primarily of net proceeds of $24.1 million from the initial public
offering of the Company's Common Stock in November 1996 offset by the purchase
of $2.0 million of treasury stock. In 1997, the cash used in financing
represented repayment of IPC's line of credit of approximately $700,000 and
payment of loans to related parties of approximately $437,000, offset by
$683,000 received in connection with the issuance common stock pursuant to the
both the exercise of stock options and purchases under the employee stock
purchase plan. In 1998, the cash provided by financing included $1.2 million and
$2.0 million borrowings under the equipment line of credit and line of credit,
respectively, and by $914,000 received in connection with the issuance of common
stock pursuant to both the exercise of stock options and purchases under the
employee stock purchase plan.

     The Company has a $6.0 million revolving line of credit and a $3.0 million
equipment line of credit with a bank. The revolving line of credit expires in
October 1999 and the equipment line of credit expires in June 1999.  Borrowings
under the lines of credit are secured by substantially all of the Company's
assets.  Loans made under the revolving line of credit generally bear interest
at a rate per annum equal to the bank's base rate plus .5% (8.25 % at December
31, 1998).  Loans made under the equipment loan bear interest at a rate per
annum equal to the bank's base rate plus 1.0% (8.75 % at December 31, 1998). The
loan agreement relating to the lines of credit requires that the Company provide
the bank with certain periodic financial reports and comply with certain
financial ratios including the maintenance of total liabilities, excluding
deferred revenue, to net worth of at least .80 to 1.0.  At December 31, 1998 the
Company was in compliance with all covenants.  As of December 31, 1998, the
Company had borrowed $2.0 million and $1.2 million against the line of credit
and the equipment line of credit, respectively.

     The Company believes that existing funds together with available borrowings
under the line of credit and equipment line facility are adequate to satisfy its
working capital and capital expenditure requirements for the foreseeable future.

     The Company had no material capital expenditure commitments as of 
December 31, 1998.


Year 2000 Issue/Year 2000 Readiness Disclosure

     Overview. The Company is completing its process of analyzing and addressing
what is known as the Year 2000 Issue. The Year 2000 Issue has arisen because
many existing computer programs use only two digits to identify a year in the
data field. These programs were designed and developed without considering the
impact of the upcoming change in the century and, accordingly, could misconstrue
dates such as "00" as the year 1900 rather than 2000. The failure of computer
programs and systems to properly recognize dates beginning in the year 2000
could adversely affect the Company's business activities.

     The Company's Year 2000 Compliance Program.  The Company is executing its
Year 2000 Compliance Program, the purpose of which is: to identify important
systems that are not yet Year 2000 compliant; to initiate replacement or
remedial action to assure that key systems will continue to operate in the Year
2000 and to test the replaced or remediated systems; to identify and contact key
suppliers, vendors, customers and business partners to evaluate their ability to
maintain normal operations in the Year 2000; and to develop appropriate
contingency plans for dealing with foreseeable Year 2000 complications.  The
Company's Year 2000 Committee has made significant progress toward the
completion of these goals.  The Committee continues to execute the Company's
Year 2000 Compliance Program and reports the results and status of the Company's
Year 2000 efforts to the Board of Directors.  The Company expects to
substantially complete its Year 2000 Compliance Program activities by the end of
1999.

     Information Technology Systems. The Company's critical internal information
technology ("IT") systems consist of its Electronic Mail system, Corporate
Communications system, Manufacturing database, desktop and file management
systems, Software Development tools and I/S Management tools. The Company also
uses a Call Center Management software tool for use in the Company's customer
service department. The Company has contacted the vendors of these systems and
obtained assurances that these IT systems are currently in material Year 2000
compliance. The Company continues to upgrade older versions of these systems
that may not be compliant and intends to finish these upgrades to achieve
material Year 2000 compliance. The Company is in the process of obtaining
written statements confirming such compliance from these vendors. The Company is
still in the process of evaluating other areas of its existing internal IT
systems at this time and will seek further assurances from its vendors as
necessary. The Company plans to test its critical IT systems during 1999. The
Company intends to evaluate the need for contingency plans for these internal IT
systems given the assurances of compliance the Company has received for these
systems. While the Company will work diligently with all of its IT system
providers, there is no guarantee that these IT system providers will meet Year
2000 compliance. The failure of any such IT system to be Year 2000 compliant
could have a negative effect on the business activities of the Company.

                                       29
<PAGE>
 
     Non-Information Technology Systems. The Company is conducting an assessment
of its non-information technology systems (such as building security, voice
mail, telephone and other systems containing embedded microprocessors) and is in
the process of determining the nature and extent of any work that may be
required to make any non-IT systems Year 2000 compliant. The Company has made
Year 2000 compliance inquiries to the vendors of these systems, and intends to
track the responses to its inquiries and have the inquiry process completed
during the first half of 1999.

     Third Party Suppliers, Vendors and Customers.  The Company's Year 2000
Compliance Program also includes an investigation of the Year 2000 compliance of
its major suppliers, vendors, customers and business partners.  For example, all
of the Company's products and services incorporate third party software and
hardware.  The Company is in the process of evaluating its product components.
The Company has identified and contacted most of its third party suppliers of
hardware and software components regarding Year 2000 compliance and has
collected compliance statements from most of these suppliers.  The Company has
learned that some features or functions of such third party components are not
Year 2000 compliant.  However, in certain cases the Company does not use such
features or functions in its products and, to that extent, the Company believes
the non-compliance of such features and functions will not have a negative
impact on its products.  In those cases where the non-compliance of third party
components does affect features or functions used by the Company in its
products, the Company intends to install upgrades (most of which are currently
available) to achieve material compliance.  In addition, the Company is
completing the process of testing its application software.  To date, the
Company has found only a few minor problems with its application software, and
has already created patches to this software.  Given the number of components
and the complexity of the software incorporated in the Company's products and
services, the Company believes that in the course of conducting its Year 2000
Compliance Program it could reasonably discover that the Year 2000 problem may
affect its software or components.  However, the Company regularly develops
software updates to its product offerings as a natural course of business and
the Company does not expect that these Year 2000 updates will be excessively
complex or expensive to implement.  Still, there can be no assurances that there
will be no service interruption on the part of any of the Company's third party
suppliers due to the Year 2000 problem and this could have a material adverse
effect on the Company.

     Year 2000 Costs and Expenses.  To date, the costs associated with the Year
2000 Issue and the Company's Year 2000 Compliance Program have not been
material.  The Company will incur costs that include internal resources,
software and equipment upgrades and replacement.  Based on currently available
information, the Company believes that the expense associated with its ongoing
efforts will not be material and will be funded through operations, but the
Company has not completed its evaluation of its non-IT systems and its third
party relationships.  If unforeseen compliance efforts are required or if
present compliance efforts are not completed on time, or if the cost of any
required updating, modification or replacement of the Company's systems or
equipment exceeds the Company's estimates, the Year 2000 Issue could result in
material costs and have a material adverse effect on the Company.

     Contingency Plans.  At the present time, the Company has not felt it
necessary to formulate any contingency plans for addressing problems due to the
Year 2000 Issue.  The Company has been assured that its critical internal IT
systems are compliant by the vendors of those systems and the Company will
evaluate the need for contingency plans for internal IT systems given those
assurances.  The Company is currently in the process of evaluating the Year 2000
Issue with respect to its non-IT systems and with respect to its major
suppliers, vendors, customers and business partners.  As this evaluation process
proceeds, the Company will formulate appropriate contingency plans.  The Company
expects that any required contingency planning will be completed no later than
the end of 1999.

     Risks Associated with Year 2000 Issue.  Various statements in this
discussion of Year 2000 are forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995 as discussed above under
"Factors That May Affect Future Results."  These statements include statements
of the Company's expectations, statements with regard to schedules and expected
completion dates and statements regarding expected Year 2000 compliance.

                                       30
<PAGE>
 
These forward-looking statements are subject to various risk factors which may
materially affect the Company's efforts to achieve Year 2000 compliance. These
risk factors include the inability of the Company to complete the plans and
modifications that it has identified; the failure of software vendors to deliver
the upgrades and repairs to which they have committed; the wide variety of
information technology systems and components, both hardware and software, that
must be evaluated; any inaccuracy in the assessment of the cost and financial
exposure of the Company with respect to current and older versions of the
Company's products; the failure of software vendors to deliver upgrades and
repairs to which they have committed; and the large number of vendors and
customers with which the Company interacts. The Company's assessments of the
effects of Year 2000 on the Company are based, in part, upon information
received from third parties and the Company's reasonable reliance on that
information. Therefore, the risk that inaccurate information is supplied by
third parties upon which the Company reasonably relied must be considered as a
risk factor that might affect the Company's Year 2000 efforts. The Company is
attempting to reduce the risks by utilizing an organized approach, extensive
testing, and allowance of ample contingency time to address issues identified by
tests.

Effects of Inflation

     Management believes that financial results have not been significantly
impacted by inflation and price changes.

ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk

     The Company faces exposure to financial market risks, including adverse
movements in foreign currency exchange rates and changes in interest rates.
These exposures may change over time as business practices evolve and could have
a material adverse impact on the Company's financial results.  The Company's
primary exposure has been related to local currency revenue and operating
expenses in Europe and Asia.  Historically, the Company has not hedged specific
currency exposures as gains and losses on foreign currency transactions have not
been material to date.  At December 31, 1998, the Company had $3,226,000
outstanding related to variable rate U.S. dollar denominated shor-term debt.
The carrying value of these short-term borrowings approximates fair value due to
the short maturities of these instruments.  Assuming a hypothetical 10% adverse
change in the interest rate, interest expense on these short-term borrowings
would increase by $40,000.

     The carrying amounts reflected in the consolidated balance sheet of cash
and cash equivalents, trade receivables, and trade payables approximates fair
value at December 31, 1998 due to the short maturities of these instruments.

     The Company maintains investment portfolio holdings of various issuers,
types, and maturities. The Company's cash and marketable securities include cash
equivalents, which the Company considers investments to be purchased with
original maturities of three months or less given the short maturities and
investment grade quality of the portfolio holdings at December 31, 1998, a sharp
rise in interest rates should not have a material adverse impact on the fair
value of the Company's investment portfolio. As a result, the Company does not
currently hedge these interest rate exposures.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of SeaChange International, Inc.

     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of SeaChange
International, Inc. and its subsidiaries at December 31, 1997 and 1998 and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1998, in conformity with generally accepted
accounting principles.  These financial statement are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits.  We conducted our audits of these
financial statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement.  An
audit includes examing, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation.  We believe that our audits provide a
reasonable basis for the opinion expressed above.

                  Notes to Consolidated Financial Statements


1.  Nature of Business

    The Company develops computer systems to digitally manage, store and
    distribute video.  Through December 31, 1998, substantially all of the
    Company's revenues were derived from the sale of digital video insertion,
    movie and broadcast systems and related services and content to cable
    television operators, broadcast and telecommunications companies in the
    United States and internationally.

2.  Summary of Significant Accounting Policies

    Significant accounting policies followed in the preparation of the
    accompanying consolidated financial statements are as follows:

    Principles of Consolidation

    The consolidated financial statements include the accounts of the Company
    and its subsidiaries.  All significant intercompany accounts and
    transactions have been eliminated.

    Revenue Recognition

    Revenues from the sales of systems are recognized upon shipment provided
    that there are no uncertainties regarding customer acceptance and collection
    of the related receivables is probable.  If such uncertainties exist, such
    as performance criteria beyond the Company's standard terms and conditions,
    revenue is recognized upon customer acceptance.  Installation and training
    revenue is deferred and recognized as these services are performed.  Revenue
    from technical support and maintenance contracts is deferred, if billed in
    advance, and recognized ratably over the period of the related agreements,
    generally twelve months. Revenue from content fees, primarily movies, is
    recognized in the period earned based on noncancelable agreements.  Customer
    deposits represent advance payments from customers for systems.

    Concentration of Credit Risk

    Financial instruments which potentially expose the Company to concentrations
    of credit risk include trade accounts receivable and marketable securities.
    To minimize this risk, the Company evaluates customers' financial condition,
    requires advance payments from certain of its customers and maintains
    reserves for potential credit losses.  At December 31, 1997 and 1998, the
    Company had an allowance for doubtful accounts of $559,000 and $870,000,
    respectively, to provide for potential credit losses and such losses to date
    have not exceeded management's expectations.  The Company invests its excess
    cash in marketable securities, such as money market funds and municipal
    securities with strong credit ratings.

    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, the
    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 these estimates.

    Cash and Cash Equivalents

    The Company considers all highly liquid investments purchased with an
    original maturity of three months or less at the date of purchase to be cash
    equivalents.  The Company invests its excess cash in money market funds,
    municipal securities and corporate debt securities that are subject to
    minimal credit and market risk.  Cash equivalents are classified as
    available-for-sale and are carried at market value, and any unrealized gains
    or losses are recorded as a part of stockholders' equity.

            Notes to Consolidated Financial Statements (continued)

    Property and Equipment

    Property and equipment consist of office and computer equipment, leasehold
    improvements, demonstration equipment, deployed assets and spare components
    and assemblies used to service the Company's installed base.  Demonstration
    equipment consists of systems manufactured by the Company for use in
    marketing and selling activities.  Property and equipment are recorded at
    cost and depreciated using the straight-line method over their estimated
    useful lives.  Leasehold improvements are amortized over the shorter of
    their estimated useful lives or the term of the respective leases by use of
    the straight-line method.  Deployed assets consist primarily of hardware
    owned and operated by the Company and installed at customer locations.
    Deployed assets are depreciated over the life of the related service
    agreements ranging from 3 to 7 years.  Maintenance and repair costs are
    expensed as incurred.  Significant improvements are capitalized and
    depreciated.  Upon retirement or sale, the cost of the assets disposed of,
    and the related accumulated depreciation, are removed from the accounts, and
    any resulting gain or loss is included in the determination of net income.

    Inventories

    Inventories are stated at the lower of cost or market.  Cost is determined
    using the first-in, first-out (FIFO) method.  Inventories consist primarily
    of components and subassemblies and finished products held for sale.  Rapid
    technological change and new product introductions and enhancements could
    result in excess or obsolete inventory.  To minimize this risk, the Company
    evaluates inventory levels and expected usage on a periodic basis and
    records valuation allowances as required.

    The Company is dependent upon certain vendors for the manufacture of
    significant components of its digital advertising insertion, movie and
    broadcast systems.  If these vendors were to become unwilling or unable to
    continue to manufacture these products in required volumes, the Company
    would have to identify and qualify acceptable alternative vendors.  The
    inability to develop alternate sources, if required in the future, could
    result in delays or reductions in product shipments and thereby adversely
    affect the Company's revenue and profits.

    Goodwill and Intangible Assets

    Goodwill and assembled workforce are amortized on a straight-line basis over
    five to seven years.  Software acquired in connection with acquisitions is
    amortized over the greater of the amount computed using (a) the ratio that
    current gross revenues for related products bear to total current and
    anticipated future gross revenues for that product or (b) on a straight-line
    basis over the estimated remaining life of the software.  The Company
    reviews goodwill and intangible assets for any impairment in accordance with
    Statement of Financial Accounting Standards No. 121, Accounting for
    Impairment of Long-Lived Assets to be Disposed Of, ("SFAS 121").

    Research and Development and Software Development Costs

    Costs incurred in the research and development of the Company's products are
    expensed as incurred, except for certain software development costs.  Costs
    associated with the development of computer software are expensed prior to
    establishing technological feasibility and capitalized thereafter until the
    product is released for sale.  Software development costs eligible for
    capitalization to date have not been material to the Company's financial
    statements. Costs associated with acquired software rights are capitalized
    if technological feasibility of the software has been established.


    Stock Compensation

    Employee stock awards under the Company's compensation plans are accounted
    for in accordance with Accounting Principles Board Opinion No. 25,
    Accounting for Stock Issued to Employees, ("APB 25") and related
    interpretations. The Company provides the disclosure requirements of
    Statement of Financial Accounting Standards No. 123, Accounting for Stock-
    Based Compensation, ("SFAS 123") and related interpretations.  Nonemployee
    stock awards are accounted for in accordance with Emerging Issues Task Force
    Issue No. 96-18.

            Notes to Consolidated Financial Statements (continued)

    Foreign Currency Translation

    The Company has determined that the functional currency of its foreign
    subsidiaries is the local currency.  Accordingly, assets and liabilities are
    translated to U.S. dollars at current exchange rates as of each balance
    sheet date.  Income and expense items are translated using average exchange
    rates during the year.  Cumulative currency translation adjustments are
    presented as a separate component of stockholders' equity.  Transaction
    gains and losses and unrealized gains and losses on intercompany receivables
    are recognized in the Statement of Operations and have not been material to
    date.

    Advertising Costs

    Advertising costs are charged to expense as incurred.  Advertising costs
    were $328,000, $659,000 and $624,000 for the years ended December 31, 1996,
    1997 and 1998, respectively.


    Earnings Per Share

    Earnings per share are presented in accordance with Statement of Financial
    Accounting Standards No. 128, Earnings Per Share, ("SFAS 128") which
    requires the presentation of  "basic" earnings per share and "diluted"
    earnings per share.  Basic earnings per share is computed by dividing income
    available to common shareholders by the weighted-average shares of common
    stock outstanding during the period.  For the purposes of calculating
    diluted earnings per share the denominator includes both the weighted
    average number of shares of common stock outstanding during the period and
    the weighted average number of potential common stock, such as stock options
    and restricted stock.

    For the years ended December 31, 1997 and 1998, 468,311 and 240,644 common
    shares issuable upon the exercise of stock options, respectively, and
    2,661,825 and 1,194,488 shares of unvested restricted common stock,
    respectively, are antidilutive because the Company recorded a net loss for
    the years and, therefore, have been excluded from the diluted earnings per
    share computations.

    Below is a summary of the shares used in calculating basic and diluted
    earnings per share for the years indicated:

    New Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board issued Statement of
     Financial Accounting Standards No. 133, Accounting for Derivative
     Instruments and Hedging Activities, ("SFAS 133"). SFAS 133 will become
     effective in January 2000. SFAS 133 requires that all derivative
     instruments be recorded on the balance sheet at their fair value.  Changes
     in the fair value of derivatives are recorded each period in current
     earnings or other comprehensive income,

     depending on whether a derivative is designated as part of a hedge
     transaction and, if it is, the type of hedge transaction. To date the
     Company has not utilized derivative instruments or hedging activities and,
     therefore, the adoption of SFAS 133 is not expected to have a material
     impact on the Company's financial position or results of operations.

5.  Acquisition and Restructuring of Operations

    Acquisition

    On December 10, 1997, the Company exchanged 625,000 shares of its common
    stock for all of the outstanding capital stock of IPC Interactive Pte. Ltd.
    ("IPC") which was renamed to SeaChange Asia Pacific Operations Pte. Ltd.
    ("SC Asia").  SC Asia provides interactive television network systems to the
    hospitality and commercial property markets. The total purchase price,
    including transaction costs, was $4,805,000.  The acquisition was accounted
    for under the purchase method.  Accordingly, the purchase price was
    allocated to the estimated fair value of the acquired assets and liabilities
    based upon an independent appraisal.  A portion of the purchase price was
    allocated to in-process research and development, resulting in an immediate
    charge to the Company's operations of  $5,290,000 at the date of
    acquisition.  The amount allocated to in-process research and development
    represented technology which had not reached technological feasibility and
    had no alternative future use.   The appraisal also valued intangibles,
    including assembled workforce and software.  Goodwill and intangibles, net
    of related accumulated amortization totaled $1,608,000 and $1,197,000 at
    December 31, 1997 and 1998, respectively.  Amortization expense was $27,000
    and $411,000 for the years ended December 31, 1997 and 1998, respectively.
    The consolidated results of operations include the operating results of IPC
    from the date of acquisition.

    The purchase price was allocated to the acquired assets and liabilities
    as follows:

    Included in assumed liabilities were a line of credit of $700,000 and notes
    payable to related parties of $437,000.  The notes payable to related
    parties were due to two companies owned by new shareholders of the Company
    as a result of the acquisition.  The Company paid these assumed liabilities
    in full and canceled the line of credit prior to December 31, 1997.

    The following unaudited pro forma data summarizes the consolidated results
    of the Company and IPC as if the acquisition had occurred on February 1,
    1996 (inception of IPC) and excludes the $5,290,000 charge for in-process
    research and development.  The unaudited pro forma information is not
    necessarily indicative either of results of operations that would have
    occurred had the purchase been made at the beginning of the periods
    presented, or of future results of operations of the combined companies.

    Restructuring of Operations

    In March 1998, the Company recorded a charge of $676,000 for the
    restructuring of operations as part of a planned consolidation of the
    operations of SC Asia. The charge for restructuring included $569,000
    related to the termination of 13 employees, a provision of $60,000 related
    to the planned vacating of premises and $47,000 of compensation expense
    associated with stock options for certain terminated employees. At March 31,
    1998, the Company had notified all terminated employees. All restructuring
    charges were paid as of December 31, 1998.

6.  Lines of Credit

    The Company has a $6.0 million revolving line of credit and a $3.0 million
    equipment line of credit with a bank. The revolving line of credit expires
    in October 1999 and the equipment line of credit expires in June 1999.
    Borrowings under the lines of credit are secured by substantially all of the
    Company's assets.  Loans made under the revolving line of credit generally
    bear interest at a rate per annum equal to the bank's base rate plus .5%
    (8.25 % at December 31, 1998).  Loans made under the equipment loan bear
    interest at a rate per annum equal to the bank's base rate plus 1.0% (8.75%
    at December 31, 1998). The loan agreement relating to the lines of credit
    requires that the Company provide the bank with certain periodic financial
    reports and comply with certain financial ratios including the maintenance
    of total liabilities, excluding deferred revenue, to net worth of at least
    .80 to 1.0.  At December 31, 1998 the Company was in compliance with all
    covenants.  As of December 31, 1998, borrowings against the line of credit
    were $2.0 million. As of December 31, 1998, borrowings against the equipment
    line of credit were $1,226,000.  Maturities of the equipment line of credit

    Deferred income taxes reflect the tax impact of temporary differences
    between the amount of assets and liabilities for financial reporting
    purposes and such amounts as measured by tax laws and regulations.  Under
    Statement of Financial Accounting Standards No. 109, "Accounting for Income
    Taxes", the benefit associated with future deductible temporary differences
    is recognized if it is more likely than not that the benefit will be
    realized.  The measurement of deferred tax assets is reduced by a valuation
    allowance if, based upon the weight of available evidence, it is more likely
    than not that some or all of the deferred tax assets will not be realized.

    The valuation allowance of $3,361,000 at December 31, 1997 and 1998 relates
    to net operating loss carryforwards and tax basis differences acquired in
    the Company's purchase of SC Asia.  These acquired deferred tax assets may
    only be utilized to offset future taxable income attributable to SC Asia.
    In addition, the recognition of these deferred tax assets are subject to
    Internal Revenue Code change in ownership rules which may limit the amount
    that can be utilized to offset future taxable income.  The Company believes
    that the valuation allowance is appropriate given the weight of objective
    evidence, including the historical operating results of IPC. Any tax
    benefits subsequently recognized related to these assets will first reduce
    the remaining balance in goodwill and then other acquired intangible assets.

    Based on the weight of available evidence, the Company believes its
    remaining deferred tax assets will be realizable.  The amount of the
    deferred tax asset considered realizable is subject to change based on
    future events.  The Company will assess the need for the valuation allowance
    at each balance sheet date based on all available evidence.

    At December 31, 1998, the Company had federal and state net operating loss
    carryforwards of approximately $11,278,000 which expire at various dates
    through 2013 and foreign net operating loss carryforwards of approximately
    $1,436,000 which do not expire.

    The income tax provision computed using the federal statutory income tax
    rate differs from the Company's effective tax rate primarily due to the
    following:

    The Company's effective tax rate was 36.8% in 1996.  The Company's effective
    tax rate for 1997 was significantly impacted by the write-off of acquired
    in-process research and development which, due to the tax-free nature of the
    transaction to IPC stockholders, is not deductible for tax purposes by the
    Company.  Accordingly, in 1997 the Company recorded a tax provision of
    $1,776,000 despite a book pre-tax operating loss. The Company's effective
    tax benefit rate was 37.2% in 1998.

8.  Common Stock

    Initial Public Offering

    On November 5, 1996, the Company sold 1,810,000 shares of common stock to
    the public in the Company's initial public offering at a price of $15.00 per
    share.  Proceeds to the Company, net of offering expenses, amounted to
    $24,070,000. Upon the closing of the initial public offering all outstanding
    convertible preferred stock of the Company automatically converted into a
    total of 2,260,856 shares of common stock of the Company.


    Stock Split

    On September 6, 1996, the Board of Directors authorized a 3-for-2 stock
    split of the Company's common stock, which became effective on October 30,
    1996.  All shares of common stock, common stock options, preferred stock
    conversion ratios and per share amounts included in the accompanying
    consolidated financial statements have been adjusted to give retroactive
    effect to the stock split for 1996.

    Restriction Agreements

    Certain common shares are subject to stock restriction and repurchase
    agreements under which the Company may repurchase unvested common shares at
    the original issuance price and vested common shares at fair value upon
    termination of a business relationship with the Company.  Common shares
    subject to these agreements vest ratably over a five-year period and, at
    December 31, 1998, 652,500 of such shares are unvested.

    Treasury Stock

    In January 1996, the Company repurchased 431,250 shares of its common stock
    and 1,286 shares of Series A Stock from certain employees and directors of
    the Company.  Of the common stock repurchased, 21,750 shares were held by
    the stockholders for less than six months from the time the shares became
    vested.  Accordingly, compensation expense was recorded for the difference
    between the repurchase price and the original purchase price paid by the
    stockholders.  Compensation expense recorded as a result of this transaction
    was $91,000.  In December 1996, the Board of Directors voted to retire all
    shares of treasury stock held at December 31, 1996.

    In 1997, the Company repurchased 9,000 shares of its common stock from an
    employee of the Company.  The shares were held for less than six months from
    the time the shares became vested.  Accordingly, compensation expense was
    recorded for the difference between the repurchase price and the original
    purchase price paid by the stockholder.  Compensation expense recorded in
    1997 as a result of this transaction was $45,000.

    Reserved Shares

    At December 31, 1998, the Company had 2,008,895 shares of common stock
    reserved for issuance upon the exercise of common stock options and the
    purchase of stock under the Employee Stock Purchase Plan.

9.  Convertible Preferred Stock

    Stock Authorization

    The Board of Directors is authorized to issue from time to time up to an
    aggregate of 5,000,000 shares of preferred stock, in one or more series.
    Each such series of preferred stock shall have the number of shares,
    designations, preferences, voting powers, qualifications and special or
    relative rights or privileges to be determined by the Board of Directors,
    including dividend rights, voting rights, redemption rights and sinking fund
    provisions, liquidation preferences, conversion rights and preemptive
    rights.

10. Stock Plans

    Employee Stock Purchase Plan

    In September 1996, the Company's Board of Directors adopted and the
    stockholders approved an employee stock purchase plan (the "Stock Purchase
    Plan"), effective January 1, 1997, which provides for the issuance of a
    maximum of 300,000 shares of common stock to participating employees who
    meet eligibility requirements.  Employees who would immediately after the
    grant own 5% or more of the total combined voting power or value of the
    Company's stock and directors who are not employees of the Company may not
    participate in the Stock Purchase Plan.  The purchase price of the stock is
    85% of the lesser of the average market price of the common stock on the
    first or last business day of each six-month plan period.  During 1997 and
    1998, 29,361 and 52,771 shares of common stock, respectively, were issued
    under the Stock Purchase Plan.

    1995 Stock Option Plan

    The 1995 Stock Option Plan (the "1995 Stock Option Plan") provides for the
    grant of incentive stock options and nonqualified stock options for the
    purchase of up to an aggregate of 1,950,000 shares of the Company's common
    stock by officers, employees, consultants and directors of the Company. The
    Board of Directors is responsible for administration of the 1995 Stock
    Option Plan and determining the term of each option, option exercise price,
    number of shares for which each option is granted and the rate at which each
    option is exercisable. Options generally vest ratably over five years. The
    Company may not grant an employee incentive stock options with a fair value
    in excess of $100,000 that are initially exercisable during any one calendar
    year.

    Incentive stock options may be granted to employees at an exercise price per
    share of not less than the fair value per common share on the date of the
    grant (not less than 110% of the fair value in the case of holders of more
    than 10% of the Company's voting stock).  Nonqualified stock options may be
    granted to any officer, employee, director or consultant at an exercise
    price per share as determined by the Company's Board of Directors.

    Options granted under the 1995 Stock Option Plan generally expire ten years
    from the date of the grant (five years for incentive stock options granted
    to holders of more than 10% of the Company's voting stock).

    Director Stock Option Plan

    In June 1996, the Company's Board of Directors adopted and the stockholders
    approved a director stock option plan (the "Director Option Plan") which
    provides for the grant of options to full time directors of the Company to
    purchase a maximum of 30,000 shares of common stock under the Director
    Option Plan.  Under the Director Option Plan, participating directors
    receive an option to purchase 3,375 shares of common stock per annum.
    Options granted under the Director Option Plan vest as to 33-1/3% of the
    shares underlying the option immediately upon the date of the grant, and
    vest as to an additional 8-1/3% of the shares underlying the option at the
    end of each of the next 8 quarters, provided that the optionee remains a
    director.  Directors will also receive, on each three-year anniversary of
    such director's option grant date, an additional option to purchase 3,375
    shares of common stock, provided that such director continues to serve on
    the Board of Directors.  All options granted under the Director Option Plan
    have an exercise price equal to the fair value of the common stock on the
    date of grant and a term of ten years from the date of grant.

    Transactions under the 1995 Stock Option Plan and the Director Option Plan
    during the years ended December 31, 1996, 1997 and 1998 are summarized as

    Fair Value Disclosures

    The Company applies APB 25 in accounting for employee stock awards.
    Compensation expense of  $126,000, $45,000 and $47,000 has been recorded for
    the years ended December 31, 1996, 1997 and 1998, respectively.  Had
    compensation expense for the Company's employee stock plans been determined
    based on the fair value at the grant dates, as prescribed in SFAS 123, the
    Company's net income (loss) and earnings (loss) per share would have been as
    follows:

</TABLE>

    For options granted prior to the Company's initial filing of its
    Registration Statement on Form S-1 on September 18, 1996, the fair value of
    each option grant was estimated on the date of grant using the minimum value
    method.  The fair value of each option granted subsequent to the initial
    filing was estimated on the date of grant assuming a weighted average
    volatility factor of 67%.  Additional weighted average assumptions used for
    grants during the years ended December 31, 1996, 1997 and 1998 included:
    dividend yield of 0.0% for all periods; risk-free interest rates of 5.36% to
    6.49% for options granted during the year ended December 31, 1996, 5.70% to
    6.75% for options granted during the year ended December 31, 1997 and 6.00%
    for options granted during the year ended December 31, 1998; and an expected
    option term of 5 years for all periods.

    Because additional option grants are expected to be made each year, the
    above pro forma disclosures are not representative of pro forma effects of
    reported net income for future years.

    Stock Option Repricing

    On January 23, 1998, the Compensation and Option Committee of the Board of
    Directors of the Company ("Committee") determined that, because certain
    stock options held by employees of the Company had an exercise price
    significantly higher than the fair market value of the Company's common
    stock, such stock options were not providing the desired incentive to
    employees. Accordingly, the Committee granted those employees whose options
    were between $15.00 and $24.63 per share an opportunity to cancel their
    existing options for new options on a 1-for-1 basis, with a new five-year
    vesting schedule beginning on January 23, 1998. Employees whose options were
    above $24.63 were offered an opportunity to cancel their existing options
    for new options on a 2-for-3 basis, with no change in their original vesting
    schedule. As a result of this stock option repricing, new options were
    granted to purchase 212,779 shares of common stock and the average exercise
    price of such options was reduced from $22.19 per share to $8.25 per share,
    the fair market value of the Company's common stock at the close of the
    market on January 22, 1998. With the exception of one executive officer, the
    Company's directors and executive officers were not eligible to participate
    in this stock option repricing. During the execution of the stock option
    repricing plan, the Company's stock price was below $8.25 per share and,
    therefore, no compensation charge was recorded as a result of the stock
    option repricing.

11. Commitments

    The Company leases its operating facilities and certain office equipment
    under noncancelable capital and operating leases which expire at various
    dates through 2005.  Rental expense under operating leases was approximately
    $251,000,

    The Company had noncancelable purchase commitments for inventories of
    approximately $3,000,000 at December 31, 1998.

    In the ordinary course of business, the Company is subject to various types
    of litigation. In the opinion of management, all litigation currently
    pending or threatened will not have a material adverse effect on the
    Company's financial position or results of operations.

12. Employee Benefit Plan

    The Company sponsors a 401(k) retirement savings plan ( the "Plan").
    Participation in the Plan is available to full-time employees who meet
    eligibility requirements.  Eligible employees may contribute up to 15% of
    their annual salary, subject to certain limitations.  The Company matches
    contributions up to 25% of the first 6% of compensation contributed by the
    employee to the Plan.  During 1997 and 1998, the Company contributed $68,000
    and $189,000, respectively, to the Plan.  Prior to 1997, the Company did not
    make contributions to the Plan.

          Third Floor Premises until the Landlord has completed the Landlord
          Work described in Paragraph 8.1(a) below; except that Tenant shall pay

          (ii) April 1, 1999 through March 31, 2002- Thirty Nine Thousand Nine
          Hundred Eleven Dollars ($39,911) per full calendar month. This amount

          foot for Seventy-Nine Thousand Eight Hundred and Twenty-Two square
          feet (79,822 SF); and

          (iii) April 1, 2002 through the Expiration Date - Forty-Three Thousand
          Two Hundred Thirty-Six Dollars and Ninety-Two Cents ($43,236.92) per

     (d)  The monthly Base Rent for any partial month at the beginning or end of
          the Term shall be prorated at the rate of 1/30 of the then current

          (6) months free Base Rent with respect to all of the New Third Floor
          Space, beginning on the date any such space is added to the Demised
          Premises, whether as Early Space or otherwise. Thus, for example, if
          600 square feet of New Third Floor Space is added to the Demised
          Premises on June 1, 1998 and 1,200 square feet is added on July 1,
          1998 and the balance is added on August 1, 1998, the Base Rent for the
          first such space shall begin on December 1, 1998, the second such
          space on January 1, 1999 and the third such space on February 1, 1999.

     (f)  The monthly Base Rent for each of the months of May, June, July,
          August, September and October, 1998 shall be reduced by a credit in
          the amount of $2,417.72 each month (for a total reduction of
          $14,506.33) in order to reimburse Tenant for its previous payment of
          $31,772.60 as Base Rent for the month of April, 1998, or an excess
          payment of $14,506.33. Accordingly, for the months of May and June
          1998 the amount to be paid monthly for Base Rent shall be $14,808.55
          and for the months of July 1998 through October, 1998, the amount to
          be paid monthly for Base Rent shall be $21,044.51.
                                                 ---------- 


     2.   Extended Term: The Annual Base Rent for the Extended Term shall be
Ninety-Five Percent (95%) of the Fair Market Rental Value ("FMRV") at the
commencement of such Extended Term. The FMRV shall be determined as follows:

     (a)  Upon receipt by Landlord of Tenant's written notice exercising its
          option to extend the Lease as provided above in Article 3.2, Landlord
          shall within ten (10) days provide Tenant with a proposed rent
          schedule for Annual Base Rent for the Extended Term.
     
<PAGE>
 
                                       7

     (b)  Landlord and Tenant shall schedule a meeting no later than fifteen
          (15) days after receipt by Landlord of Tenant's written notice
          exercising its option, to mutually agree on a rent schedule for the
          Extended Term.

     (c)  If Landlord and Tenant are unable to agree on a rent schedule, then
          within five (5) days of the meeting each shall name and appoint a duly
          qualified and licensed real estate appraiser or appraisal firm of
          recognized competence and experience in central and eastern
          Massachusetts. The fees of each appraiser shall be paid by the
          appointing party. If for any reason either Landlord or Tenant do not
          appoint an appraiser by 5:00 PM on the fifth (5th) day, or if the
          fifth (5th) day falls on a Saturday, Sunday or a holiday, by 5:00 PM
          of the next business day, then the party making their appointment may
          request the President of the Greater Boston Real Estate Board or a
          presiding Justice of the Middlesex Superior Court appoint a second
          appraiser. The fee of the second appraiser shall be paid by the non-
          appointing party.

     (d)  Within ten (10) days of their appointment, the two appraisers shall
          appoint a third appraiser of comparable qualifications. If the two
          appraisers cannot agree on a third, then either Landlord or Tenant can
          follow the above procedure for the appointment of the third appraiser.
          The fee of the third appraiser shall be divided equally between the
          parties.

     (e)  The three appraisers shall complete their assignments and establish
          the FMRV for the Demised Premises for the period of the Extended Term
          within thirty (30) days after the appointment of the third appraiser.
          If all three appraisers are unable to agree on the FMRV, then the
          three appraisal reports shall be compared and the percent variance
          between values calculated. The two appraisals with the least variance
          between the values shall be added together and the sum divided by two
          (2), which quotient shall represent the FMRV for the Demised Premises.
          The FMRV shall be expressed in dollars per square foot per year.

     (f)  The Annual Base Rent for the Extended Term is calculated by
          multiplying the FMRV as determined by ninety-five percent (95% or
          .95).

     3.   Late Payment of Base Rent and Additional Rent: The Base Rent and the
Additional Rent shall be considered late if the payment is not received by
Landlord by 5:00 PM on the first day of each month during the Term. Landlord
shall assess and Tenant agrees to pay Landlord, as Additional Rent, a late fee
equal to five (5%) percent of the then monthly rental payment due for both Base
Rent and Additional Rent if payment is made after the fifth day of the month.

                                ARTICLE 5 - Use

demonstration purposes related to Tenant's business ("Permitted Uses"). Tenant
may use the Demised Premises for such other business use in which Tenant might
engage in the future provided that Tenant receives the prior written approval of
Landlord which approval shall not be unreasonably withheld or delayed. It shall
be the Tenant's responsibility to insure that its intended use of the Demised
Premises is in compliance with all laws, codes and regulations throughout the
Primary Term and any Extended Term of this Lease.

costs relating to the elevator at Building No. 3, and certain of the expenses
referred to in subsections (g), (h), (i), and (k) in the next following
paragraph), Tenant shall pay a share of such costs equal to the percentage
determined by taking the actual amount of space occupied by Tenant during the
Term for which Tenant is to be charged Additional Rent and dividing it by the

services.

          and the Landlord's share as employer of employee benefits, including,
          but not limited to, contributions to life insurance, hospitalization

          Article 8 shall be done at Landlord's sole cost without any
          reimbursement from Tenant unless such repair is increased as a result
          of alterations or improvements performed by Tenant and (y) Landlord

     2.   Landlord shall reasonably estimate the Operating Costs for each
calendar year wholly or partially included within the Term of this Lease. Prior
to the execution hereof, Landlord shall send notice of said estimate to Tenant
for the remaining portion of the first such calendar year and thereafter at
least thirty (30) days prior to the commencement of each subsequent calendar
year. During each calendar year thereafter included in the Term, Tenant shall
pay, as Additional Rent, one twelfth of the applicable estimate each month to
Landlord together with the fixed monthly Base Rent. If Landlord does not give
Tenant such estimate within the time period stated above, then Tenant shall
continue to make estimated payments based upon the preceding year's estimate and
within thirty (30) days after receipt of the new estimate for the current
calendar year, Tenant shall commence payment of the new estimated monthly amount
and shall pay in a lump sum any retroactive amounts due from the beginning of
the new calendar year, except that if such retroactive amount exceeds $25,000,
Tenant shall have the right to pay it in installments over a three (3) month
time period.

          It is agreed between the parties that Landlord may revise its estimate
of Operating Costs once a calendar year to reflect increased costs and shall
give notice to Tenant thereof no later than the tenth (10th) day of the month
preceding the month in which said increased Operating Costs will be applicable.
All payments made hereunder shall be paid to Landlord as stated in this Lease.

     3.   Within one hundred twenty (120) days after the expiration of each
calendar year included in the Term, Landlord shall provide Tenant with a written
statement, in sufficient detail for verification by Tenant, comparing the actual
Operating Costs for the preceding calendar year
<PAGE>
 
                                      12

against the estimate of Operating Costs for the current calendar year. Within
thirty (30) days after the delivery of such statement, including any statement
delivered after the expiration or termination of this Lease, Tenant shall pay to
Landlord the difference, if any, between the amount paid by Tenant as estimated
Operating Costs and the amount owed by Tenant for the actual Operating Costs for
such lease year, provided, however, that if Landlord does not furnish Tenant
with a statement within six (6) months after the end of the billing period for
Operating Costs, Tenant shall not be obligated to pay such amount. If Tenant's
payment of the estimated Operating Costs was greater than the amount owed by
Tenant for the actual Operating Costs, then Landlord shall pay same to Tenant
within thirty (30) days after delivery of such a statement.

          Tenant shall notify Landlord within sixty (60) days after receipt of
Landlord's statement of its intention to inspect Landlord's books and records
with respect to Landlord's maintenance and operation of the Property for the
purpose of verifying the actual Operating Costs and their inclusion and Landlord
shall promptly thereafter provide Tenant with access to such records. Tenant,
its accountant, or a qualified consultant engaged by Tenant, at Tenant's sole
cost, shall conduct and conclude its inspection of Landlord's books and records
with respect to Landlord's maintenance and operation of the Property within
thirty (30) days after Tenant's notice and access and shall be entitled, at its
expense, to make copies thereof. If such inspection reveals that Tenant's
payment of the estimated Operating Costs was greater than the amount owed by
Tenant for the actual Operating Costs, then Landlord shall pay same to Tenant
within sixty(60) days after receipt by Landlord of a written notice from Tenant
identifying the nature and amount of any overpayment.

     4.   If, during the Term of this Lease, Landlord shall make

          (i)  a Capital Expenditure, hereinafter defined, for an improvement
which produces a cost savings in operating the Land and/or Demised Premises and
of which Landlord has given information reasonably satisfactory to Tenant
demonstrating a cost savings greater than Tenant's Proportionate Share of the
Annual Amortization of such improvement as stated in the following sentence; or

          (ii) a Capital Expenditure to the Property which benefits the Demised
Premises and/or to the Demised Premises, which is required: a) to comply with
changes in laws applicable to the Property and/or the Demised Premises, or b) as
a result of an alteration or improvement performed by Tenant, except for any
such Capital Expenditure made as a result of an obligation of Landlord pursuant
to this Lease, which shall be done at Landlord's sole expense without any
reimbursement from Tenant; then Tenant shall pay Tenant's Proportionate Share of
the Annual Amortization of such Capital Expenditure. The Annual Amortization
shall be determined by dividing the cost of the original Capital Expenditure
plus an interest factor, reasonably determined by Landlord as being the interest
rate then being charged for long-term mortgages by institutional lenders on like
properties within the locality in which the Demised Premises are located, by the
number of years of the useful life of the Capital Expenditure in accordance with
GAAP.
<PAGE>
 
                                      13

          With respect to the payment of Tenant's Proportionate Share of the
Annual Amortization, Tenant shall commence payment as Additional Rent of one
twelfth (1/12th) of the annual amount shown in Landlord's notice given pursuant
to the immediately preceding sentence with the next and each succeeding
installment of rent becoming due during the Term, provided that the item for
which the expenditure was made has been fully completed on the date of Tenant's
first payment and further provided that Tenant has received notice of such
amount at least fifteen (15) days prior to the month in which payment is first
due or if not so received, then Tenant's payment shall commence as of the
following month. For purposes of this Lease, a "Capital Expenditure" is defined
as the acquisition of a prior non-existing asset or the acquisition of a
replacement of a pre-existing asset not acquired in the ordinary course of
business and not characterized as an operating cost or expense within generally
accepted accounting principles, provided that the acquired asset must enhance
the value of the real estate over its useful life, be permanently affixed to the
real estate and excludes all personal property, removable trade fixtures and
repairs to existing assets.

     5.   Notwithstanding any provisions in this Lease to the contrary, Landlord
shall perform all maintenance, repairs and replacements necessary to keep in
good condition and working order and in compliance with all applicable laws,
ordinances and regulations (a) the roof, foundation, columns and other
structural elements of the Building, (b)the heating, ventilating, air
conditioning, plumbing, electrical, life safety and other mechanical systems and
equipment serving the Building, (c) the parking areas on the Land (including
snow removal), (d) the driveways and walkways necessary for access to the
Building or the Demised Premises or such parking areas (including snow removal),
(e) the entrances (including snow removal), necessary for access to the Building
and Demised Premises, (f) the loading docks and passenger elevators in the
Building, (g) the lavatories in the Demised Premises, and (h) any common areas
and facilities provided by Landlord from time to time. When Landlord performs
maintenance, repair and replacement work, Landlord shall take care not to
unreasonably interfere with Tenant's use of the Demised Premises. If Tenant's
use of the Demised Premises is materially adversely affected for more than three
(3) consecutive business days as a result of Landlord's breach of its repair
obligations as set forth herein, then Tenant shall be entitled to an equitable
abatement of rent for each such consecutive business days that Tenant's use is
materially adversely affected.

     6.   As used herein, Real Estate Taxes shall mean general real estate taxes
levied against the Property but not any special assessments or taxes in the
nature of improvement or betterment assessments which shall be governed solely
by Paragraph 6.9. Real Estate Taxes shall also exclude, without limitation, any
income, franchise, gross receipts, corporation, capital levy, excess profits,
revenue, rent, inheritance, devolution, gift, estate, payroll or stamp tax by
whatsoever authority imposed or howsoever designated or any tax upon the sale,
transfer and/or assignment of Landlord's title or estate which at any time may
be assessed against or become a lien upon all or any part of the Demised
Premises, or this leasehold. In addition, Real Estate Taxes shall exclude any
liens or taxes, penalties or interest which are levied or assessed against the
Property for a period of time prior to the commencement of the Term or one
levied or assessed for a period during the Term on account of late payment not
caused by Tenant, or any related fees or costs, and shall also exclude all or
any portion of the Real Estate Tax Arrearage,
<PAGE>
 
                                      14

except for Tenant's Proportionate Share of Real Estate Taxes for Fiscal Year
1998 not previously paid by it.

     7.   If at any time during the Term the laws concerning the methods of real
property taxation prevailing at the commencement of the Term are changed so that
a tax or excise on rents or any other such tax, however described, is levied or
assessed against Landlord as a direct substitute in whole or in part for any
Real Estate Taxes, Tenant shall pay before delinquency (but only to the extent
that it can be ascertained that there has been a substitution and that as a
result Tenant has been relieved from the payment of Real Estate Taxes it would
otherwise have been obligated to pay) the substitute tax or excise on rents.

     8.   Tenant shall pay monthly, as part of the Additional Rent described in
Paragraph 6.2 above, Tenant's Proportionate Share of all Real Estate Taxes as
estimated by Landlord based on the tax bill for the current tax year to be
assessed against the Property for each fiscal tax year or such other tax period
as may be defined by the appropriate governmental authority having jurisdiction
or portion thereof included within the Term, and which are during such Term,
levied, or imposed upon or become a lien or liens upon the Property or any part
thereof. This part of the Additional Rent payment shall be one twelfth of the
applicable annual estimate.

          Real Estate Taxes for the tax year in which the Term of this Lease
commences and for the tax year in which such Term expires shall be apportioned
between Landlord and Tenant in accordance with the number of days thereof
falling within the Term of this Lease.

     9.   Landlord shall pay when due all special assessments and betterment
assessments for municipal improvements levied against the Property or any part
thereof during the Term. Landlord may elect to either i) pay the assessments in
full, or ii) pay in installments over the period of time and upon the terms
offered by the assessing authority.

          Tenant shall pay Tenant's Proportionate Share of any such assessments
which shall be calculated as follows: 1) using Tenant's Proportionate Share as
identified in Exhibit A -Schedule of Space and Exhibit A-2 - Building Complex
Space Allocation, 2) multiplied by the amount of the assessment attributable to
the Property, 3) divided by the maximum number of installments allowed or
allowable by the assessing authority, 4) multiplied by the interest rate
(monthly or annual) as stated by the assessing authority. Payment of any such
installment of an assessment shall be made in accordance with the Article 6.8
above.

     10.  Landlord is solely responsible for the timely payment of Real Estate
Taxes and any special assessments or betterment assessments to the Town of
Maynard. So long as no lien will be placed against the Property, Landlord, at
its sole election and its sole cost, may contest the amount of real estate taxes
to be paid, file for an abatement of real estate taxes paid, file an appeal of
the decision of the local Board of Assessors to the State Appellate Tax Board or
file a suit in a court having jurisdiction over such matters. Should Landlord
receive an abatement or an award from the court for amounts levied or assessed
for a period falling within the Term, then Landlord shall pay to Tenant Tenant's
Proportionate Share of such amount after deduction of expenses incurred in
connection therewith.
<PAGE>
 
                                      15

     11.  Landlord acknowledges that it currently owes real estate taxes and
water and sewer charges due with respect to the Property (collectively,
"Outstanding Taxes") for periods of time prior to the commencement of the Term,
as well as interest, fees, penalties and costs relating to such Outstanding
Taxes, and taxes and water and sewer charges for Fiscal Year 1998 (all such
amounts, as well as any assessments or other amounts, outstanding with respect
to the Property for any period of time prior to the Date of Execution, including
penalties and interest, collectively, referred to as the "Real Estate Tax
Arrearage"). As a material inducement to Tenant's willingness to execute this
Lease, Landlord has agreed (a) to pay to the Town of Maynard, or other
appropriate entity, the entire Real Estate Tax Arrearage on or before July 7,
1998; and (b) to provide to Tenant on or before July 8, 1998 written
verification of its payment in full of all such amounts, as well as written
verification from the Town of Maynard that it has accepted such amounts as
payment in full (such written verification referred to as the "Tax Payment
Notice"); and (c) to provide to Tenant on or before July 15, 1998 written
verification from the Town of Maynard of Tenant's and Landlord's ability to
obtain a building, occupancy, or other local permit or license for performing
alterations or improvements at, and/or the occupancy by Tenant of, the Demised
Premises (collectively, "Permits") and of the removal of any conditions or
restrictions on (or the denial, suspension or revocation of) the issuance of any
Permits resulting from the Real Estate Tax Arrearage (such written verification
referred to as the "Building Permit Notice"). In the event that Landlord has not
timely performed all of its obligations under this Section 6.11, Tenant shall be
entitled to exercise its Early Termination Right pursuant to Section 3.3.
Notwithstanding the foregoing, Landlord shall be entitled to seek relief against
the Town of Maynard with respect to such amounts so long as such actions or
litigation shall not affect Landlord's obligations in subsections (a) - (c)
above or Tenant's ability to obtain any Permits.

     12.  If the Term or Extended Term includes any partial calendar year, the
Additional Rent for such calendar year shall be prorated according to the
fraction of total days in such calendar year that are included in the Term or
Extended Term. If the Term or Extended Term begins on a day other than the first
day of a calendar month or ends on a day other than the last day of a calendar
month, then the monthly installment of Additional Rent for the month in which
the Term begins or ends shall be prorated at the rate of 1/30 of the then
current installment of Additional Rent for each day in such month.

                       ARTICLE 7- Utilities and Services

     1.   Landlord shall supply to the Building Complex, of which the Demised
Premises is a part, at no cost to Tenant, except as it may otherwise be provided
Sections 6.1,6.2 and 7.2 in this Lease, the following services, which shall be
available 24 hours per day, 7 days per week: gas, hot and cold running water for
lavatory, cooking and drinking purposes, sewer services, heating, ventilating
and air conditioning ("HVAC"), and electricity for lighting and the operation of
Tenant's business equipment and machines. HVAC service shall be provided 8 a.m.
to 6 p.m. Monday through Friday throughout the entire Demised Premises, and at
other hours to portions of the Demised Premises, at Tenant's request, through
the energy management system at the Property (the "EMS"). The Landlord shall
provide that the heating system serving the Demised Premises shall heat all
areas of the Demised Premises to an inside temperature of seventy (70) degrees
Fahrenheit when the outside temperature is zero (0) degrees Fahrenheit or above,
and
<PAGE>
 
                                      16

that the air-conditioning equipment will be of sufficient capacity to cool the
Demised Premises to seventy-five (75) degrees Fahrenheit plus or minus two (2)
degrees with a relative humidity of fifty percent (50%) plus or minus five
percent (5%) and the outside temperature is ninety-five (95) degrees dry bulb,
seventy-three (73) degrees wet bulb.

     2.   Tenant shall be responsible for the payment of all utility expenses
for those utilities serving the Demised Premises associated with the use and
occupancy of the Demised Premises including water, sewer, electricity, fuel oil
or gas. Tenant will be charged by Landlord for its actual usage of utilities as
part of the Operating Costs and which Tenant shall pay monthly as part of the
Additional Rent, described in Paragraph 6.2. Landlord represents that gas, water
and sewer service for Building No.3 are currently separately metered and that
Landlord shall, at its sole cost and expense, separately sub-meter the electric
utilities provided to Building No.3 and connect such submeter to the EMS, on or
before July 1, 1998. For any utility service provided to all or any portion of
the Demised Premises which are separately metered or submetered, Tenant shall be
charged for its actual usage as shown on such meter or sub-meter, without mark-
up.

     For any period during which any utility service provided to all or any
portion of the Demised Premises is not separately metered or sub-metered, Tenant
shall pay for such utility service, as follows. If such utility service is
provided to all tenants at the Building Complex, Tenant's share shall be
Tenant's Proportionate Share. If such utility service is provided to some, but
not all, tenants at the Building Complex, Tenant's share shall be a fraction,
the numerator of which is the square feet of the Demised Premises at the time
such service is provided and the denominator of which is the total square feet
of the premises to which such service is provided. Notwithstanding the
foregoing, if Tenant's usage significantly increases on a per square foot basis
over its current usage with respect to utilities which are not separately
metered or sub-metered, Landlord may reasonably adjust Tenant's share.

     3.   Tenant shall make its own arrangements with any utility company not
servicing the Demised Premises for any utilities that it desires that are
currently not being provided by Landlord (Landlord is not aware of any such
utility), and shall pay when due any and all charges for services supplied to
Tenant by the respective utility. In the event that Landlord is notified that a
lien will be placed against the Demised Premises as a result of Tenant's failure
to pay any such utility charge, then Landlord shall immediately notify Tenant of
the impending lien and to protect the real estate Landlord may pay such charges,
notify Tenant thereof and the same shall be paid by Tenant as Additional Rent
with the next installment of Base Rent becoming due.

     4.   In no event shall Landlord be responsible for charges for any
utilities consumed by Tenant at the Demised Premises.

     5.   Landlord shall use reasonable efforts to work with the utility
providers to restore any service which becomes unavailable. If, however, such
unavailability of any utility service has a material adverse effect on Tenant's
use and occupancy of the Demised Premises for more than ten (10) consecutive
business days, then after the tenth (10th) day Tenant shall be entitled to
<PAGE>
 
                                      17

an abatement of fifty percent (50%) of the Base Rent as prorated on a per diem
basis for each consecutive day that Tenant's use is so affected.

     6.  Landlord shall provide property management services for the Property
and the Demised Premises as provided for in Article 6 above and shown on Exhibit
B. Tenant is responsible for Tenant's Proportionate Share of the cost of said
services, the amount of which shall be identified on the Operating Cost estimate
to be delivered to Tenant as provided for in Article 6.2 above and paid monthly
as part of Additional Rent. The property management services to be rendered by
Landlord set forth in this Article shall be provided between the hours of 8 AM
and 5 PM Monday through Friday. If Tenant requires any property management
services to be performed after said hours, including Saturdays, Sundays and
holidays, Tenant shall notify Landlord of such requirement no later than 3 PM on
any week day and by 3 PM on Friday for after hours service on Saturday and/or
Sunday. The cost for such additional service shall be as provided for in Article
6.1 above

      ARTICLE 8 - Condition of the Premises, Landlord and Tenant Improvements

     1.  Condition of the Premises:

     (a) Tenant agrees to take and Landlord agrees to deliver the Demised
Premises according to Exhibit A; Schedule of Space, upon the Commencement of
this Lease, in the "as is, where is" condition, subject to Landlord's
obligations under this Article 8 and 6.5 hereof. On such date or the dates
identified in Exhibit A; Schedule of Space, or such earlier occupancy date as
provided in Article 2, the Demised Premises shall be free of all occupants and
their personal property, in good basic operating condition and repair, broom
clean and in compliance with applicable building, life and safety codes.

     (b) In addition to the foregoing, Landlord shall, on or before July 1,
1998 (a) insure that Andataco, Inc., and any other persons, currently using the
vestibule and lobby on the first floor of the Building have vacated and ceased
all use of or operation within such areas, as well as any access to or through
the lobby and vestibule, removing all signage and leaving the same in broom
clean, good condition and (b) construct a demising wall in the loading dock area
of the Connector Building, separating the Demised Premises from the remainder of
the Connector Building, as previously agreed. Landlord further agrees that it
shall, on or prior to June 1, 1998, remove from the third floor portion of the
First Additional Premises, all equipment, supplies, materials and all other
personal property.

     (c) Subject to the provisions of Article 2 relating to Early Space,
Landlord will, prior to August 1, 1998, perform the following improvements in
the third floor portion of the First Additional Premises ("Landlord Work"):
install new carpeting and ceiling tiles; paint walls; refurnish existing light
fixtures; demolition of certain demising walls as shown on a plan prepared by
John Brennan, architect, previously approved by Landlord and Tenant; and clean
and paint bathrooms. The quality and type of materials and workmanship will be
similar to the Initial Demised Premises. Landlord will have no obligation to
install any hard wall partitions or to modify the HVAC, electrical or
telecommunications system as part of Landlord Work.

     2.  Landlord Improvements and Repairs: HVAC and Air Quality:
<PAGE>
 
                                      18

     Landlord shall promptly and diligently make whatever improvements are
necessary to correct air quality problems with respect to the Demised Premises,
including addressing the problems identified in the Envirohealth Report issued
May 19, 1997. Such improvements shall include, but are not limited to:

     (a)  HVAC System

          (1)  Landlord shall provide ventilation of the Demised Premises that
               meets or exceeds the Standards for Acceptable Indoor Air Quality
               (ASHRAE 62-1989) established by the American Society of Heating,
               Refrigeration and Air-Conditioning Engineers, as such Standards
               may be amended from time to time (the "Standards"). If the
               ventilation system serving the Demised Premises fails to provide
               adequate ventilation according to the Standards, Landlord shall
               promptly and diligently make such repairs or replacements to the
               ventilation system as are necessary to comply with the Standards.

          (2)  Prior to the date hereof, Landlord has installed four (4) new
               HVAC units on the roof of Building No.3. The specifications for
               the new units includes:

               a.   Economizers pre-set to provide fresh air (outside) make up
                    at approximately fifteen percent (15%),

               b.   Power exhausts to provide proper pressure stabilization and
                    air exchange.

               c.   Humidity controls to provide for humidity levels between
                    forty-five and sixty percent (45% to 60%).

          (3)  The cost of the new HVAC units and the cleaning of the HVAC duct
               work and their installation shall be at Landlord's sole cost and
               expense and shall not be amortized and payable by Tenant as
               Additional Rent as provided for in Article 6.4 above.

          (4)  Landlord shall, throughout the Term of the Lease, be responsible
               for the inspection, repair and maintenance of the HVAC system
               serving the Demised Premises, including the two (2) units which
               are located on the roof of the Connector Building, which serve
               the Tenant's second floor computer room. Tenant shall pay
               Tenant's Proportionate Share of said expenses as provided for in
               Article 6 above. In the event that the new HVAC units serving
               Building No.3 described above (as well as the new HVAC unit
               located on the roof of Building No.3 and serving Tenant's third
               floor computer room) require repairs or replacements during the
               Term or Extended Term, Landlord shall first seek coverage or
               reimbursements for said repairs or replacements from any warranty
               or
<PAGE>
 
                                      19

               guaranty that may be in effect at that time before seeking
               reimbursement from Tenant. Landlord represents that all such new
               units are covered by a five (5) year warranty. It is understood
               by both parties that normal preventive maintenance practices
               including but not limited to oiling of motors, changing belts and
               replacing filters are not covered by a new HVAC unit warranty.

     (b)  HVAC Duct Cleaning:

          After the installation of the new HVAC units, Landlord engaged a
          qualified consultant to clean the HVAC ducts in Building No.3 as
          recommended in the EnviroHealth Report (#809-849b), issued May 19,
          1997. During this process, the consultant installed after-filters in
          the supply grills to enhance the collection of airborne dust
          particles.

     3.   Air Quality Monitoring:

          Landlord shall (a) at Landlord's sole expense, within a reasonable
amount of time following the HVAC duct cleaning (as set forth below), and at
three (3) year intervals thereafter, and (b) at Tenant's request and at Tenant's
sole expense, at other times, engage an indoor air quality professional, subject
to Tenant's approval which approval shall not be unreasonably withheld or
delayed, to inspect the HVAC system and/or conduct air quality tests, if
appropriate. Landlord shall promptly correct any problems identified by such air
quality professional. Landlord shall require such air quality professional to
provide copies of any and all reports and test data to Tenant. The first such
inspection and testing (which shall include the HVAC duct work and HVAC
machinery pans and sumps) shall be performed at Landlord's expense, and all
reports and test data delivered to Tenant by September 1, 1998.

     4.   Landlord Improvements - General:

          Landlord in making any improvements, alterations, construction or
other work, including Landlord Work, shall cause all work to be done in a good
and workmanlike manner using materials equal to or better than those used in the
construction of the Demised Premises and shall comply with or cause compliance
with all applicable building codes, health and safety regulations and zoning
laws and with any direction given by any public officer pursuant to such codes,
regulations and laws. Landlord shall obtain or cause to be obtained and maintain
in effect, as necessary, all building permits, licenses, temporary and permanent
certificates of occupancy and any other governmental approvals which may be
required in connection with the making of the improvements, alterations,
construction or other work.

     5.   Default by Landlord:

          In the event that Tenant notifies Landlord of any defaults on its
obligations under this Article, and Landlord shall fail to cure the same within
fifteen (15) days after receipt of such notice (or, as to a default under
Subsection 2(a)(4) which is not within Landlord's control, forty
<PAGE>
 
                                      20

(40) days after receipt of such notice, Tenant shall have the right to terminate
the Lease, upon fifteen (15) days written notice to Landlord.

     6.   Tenant Improvements:

     (a)  Prior to making any initial improvements to any portion of the Demised
          Premises ("Tenant Improvements"), Tenant shall give Landlord notice of
          its intentions and submit plans and specifications of the proposed
          Tenant Improvements to Landlord, for approval, which approval shall
          not be unreasonably withheld or delayed. Landlord acknowledges that
          the Tenant Improvements may include the following work:

          .  Upgraded cafeteria.

          .  Relocation of demonstration room and training room.

          .  Exercise room with shower.

          .  Relocation of existing and/or construction of new laboratories.

          .  Enlarge third floor computer room, including additional air
             conditioning and installation of condenser(s) on roof.

          .  Installation of a new card reader security system, separate from
             the current Andataco system, including electrical and low voltage
             wiring. This may include expansion of the current system in the
             manufacturing area of the first floor of the Demised Premises.

          Landlord's approval shall be deemed given if Landlord does not respond
          to Tenant's request for approval within fifteen (15) days from the
          receipt of such request. In the event that Landlord withholds approval
          for the proposed Tenant Improvements, Landlord shall state in writing
          its reasons in sufficient detail to permit Tenant to modify its plans
          in order to receive approval.

     (b)  At the time Landlord grants or is deemed to grant approval of any
          Tenant Improvements, Landlord shall inform Tenant of any of the Tenant
          Improvements that would (i) materially diminish the value of the
          Demised Premises for use by a tenant for the Permitted Uses or (ii)
          require unusual expenses to readapt the Demand Premises for use by a
          tenant for the Permitted Uses or (iii) would be unique to Tenant's
          particular business operations (except for the air handlers in
          Tenant's computer rooms), and must be removed at the end of the Term.
          If Landlord does inform Tenant of any such removal requirements, then
          Tenant may either remove or leave such Tenant Improvements as it
          decides. Tenant's responsibility upon removal of any such Tenant
          Improvement is to repair any damage caused by the removal and not to
          restore the Demised Premises.
<PAGE>
 
                                      21

     (c)  Tenant Improvements may be done by any contractor chosen by Tenant and
          approved by Landlord which approval shall not be unreasonably withheld
          or delayed. Said contractor must be licensed, carry the kinds or
          insurance and in the amounts set forth in subparagraph (f) below, and
          must not interfere with Landlord's performance of its obligations
          under this Lease.

     (d)  If Tenant retains Landlord to perform any of the work of making
          Tenant. Improvements for Tenant, Landlord shall obtain bids from three
          (3) independent general contractors. If Landlord acts as its own
          general contractor, it shall obtain three (3) bids from three (3)
          independent subcontractors for each discipline (mechanical,
          electrical, etc.). Landlord shall make its recommendation as to each
          bidder, however, Tenant shall have the right to choose the successful
          bidder in either event. If Landlord acts as its own general
          contractor, Landlord shall not receive more than ten percent (10%)
          overhead and profit based on the total cost of construction.

     (e)  Tenant in making any Tenant Improvements shall cause all work to be
          done in a good and workmanlike manner using materials equal to or
          better than those used in the construction of the Demised Premises and
          shall comply with or cause compliance with all applicable building
          codes, health and safety regulations and zoning laws and with any
          direction given by any public officer pursuant to such codes,
          regulations and laws. Tenant shall obtain or cause to be obtained and
          maintain in effect, as necessary, all building permits, licenses,
          temporary and permanent certificates of occupancy and any other
          governmental approvals which may be required in connection with the
          making of the Tenant Improvements. Landlord shall cooperate with
          Tenant in the obtaining thereof and shall execute any documents
          reasonably required in the furtherance of such purpose, provided any
          such cooperation shall be without expense and/or liability to
          Landlord.

     (f)  Tenant shall have its contractor procure and maintain in effect during
          the term of such Tenant Improvements, the following insurance
          coverages with an insurance company or companies with a Best's rating
          of A- or better and authorized to do business in the Commonwealth of
          Massachusetts.

          (1)  Workmen's Compensation Insurance-Statutory limits for the
               Commonwealth of Massachusetts.

          (2)  Employer's Liability insurance meeting the requirements of
               Massachusetts law.

alterations to install additional microwave dishes on the roof of Building No.3,
which installation may include roof penetration, and on the roof of the Building

<PAGE>
 
                                      23

Landlord after the expiration of the Term (or Extended Term), so long as there
is no disruption of or interference with Tenant's operations.

              ARTICLE 9 - Alterations, Additions and Improvements

     Upon completion of the initial Tenant Improvements to any portion of the
Demised Premises, Tenant may, from time to time, at its own cost and expense and
without the consent of Landlord make alterations, additions or improvements
(collectively herein called "Alterations") of a non-structural nature to the
Demised Premises which cost in any one instance is Ten Thousand and 00/100
Dollars ($10,000.00) or less, provided Tenant first notifies Landlord in writing
of any such Alterations. If Tenant desires to make any structural Alterations
costing any amount or any non-structural Alterations which costs in any one
instance exceed Ten Thousand and 00/100 Dollars ($10,000.00), Tenant must first
give Landlord notice of its intentions and submit plans and specifications of
the proposed Alterations to Landlord, for approval, which approval shall not be
unreasonably withheld or delayed. With respect to all of the other aspects of
any proposed Alterations, including Landlord approvals, selection of
contractors, the Landlord as contractor, materials and workmanship, licenses and
permits, and the insurances to be carried, the provisions of Article 8.4(a)
through (g) above apply. Such alterations may include, without limitation, some
or all of the items referred to in Section 8.6(a).

                       ARTICLE 10 - Compliance with Laws

     1.  Tenant shall be responsible throughout the Term or Extended Term for
procuring all licenses and permits for the Demised Premises required for the
operation of Tenant's business including Tenant's sign. Tenant agrees that it
shall do nothing, during the Term or Extended Term, in its use and occupancy of
the Demised Premises which would cause the Demised Premises to be in non-
compliance with any applicable governmental laws, codes, ordinances, rules and
regulations to the extent the same apply to Tenant's use and occupancy of the
Demised Premises as opposed to laws of general applicability. In the event that
Tenant receives notice of non-compliance with laws relating to Tenant's use and
occupancy, as provided for in Article 5, by any governmental authority having
jurisdiction over the Property, Tenant shall diligently pursue remediation of
the problem and shall correct the non-compliance within the period of time
prescribed by the governmental authority unless it is determined that such
remediation and correction work falls within the Landlord's responsibilities and
obligations under this Lease whereupon Tenant shall provide Landlord with
written notice of the non-compliance and identify Landlord's responsibilities
and obligations under the Lease.

     2.  Tenant shall have the right, at its expense, to contest, by appropriate
legal proceedings conducted in good faith with due diligence, the validity or
applicability, in whole or in part, of any governmental laws, codes, ordinances,
rules and regulations pursuant to which such notice of non-compliance was
issued, and, so long as such proceedings are being conducted in good faith and
with due diligence Tenant may defer compliance therewith pending the outcome of
that contest provided that such deferral shall not: i) result in any deprivation
in the use of the Property by any party entitled thereto; or ii) result in any
criminal or civil liability on the part of the Landlord. Landlord shall, upon
request by Tenant, cooperate with any such
<PAGE>
 
                                      24

contest provided that Tenant shall pay all actual out-of-pocket costs incurred
by Landlord in connection therewith.

     3.  In the event that a capital expenditure is required to make an
Alteration to the Demised Premises so that it is in compliance with all
statutes, codes, regulations and other laws as a result of Tenant's use of the
Demised Premises (excluding any Capital Expenditures which fall within
Landlord's responsibilities and obligations under this Lease included in Article
6 and 8), Tenant shall be responsible for making any such expenditure and
Alteration. Upon receipt of notice of non-compliance by any governmental
authority having jurisdiction over the Demised Premises, Tenant shall diligently
pursue remediation of the problem and shall correct the noncompliance within the
period of time prescribed by the governmental authority. The provisions of
Article 8.6 and 9 above apply in the remediation of any non-compliance. Landlord
agrees to cooperate fully with Tenant in correcting the item(s) of non-
compliance.

     4.  In the event that Landlord receives notice of non-compliance with any
law, ordinance, code, rule or regulation relating to the Land and/or Building
(and any systems therein) and/or the Property by any governmental authority
having jurisdiction over the Property, Landlord shall diligently pursue
remediation of the problem at its expense subject to the provisions of Article
6.4 and shall correct the non-compliance within the period of time prescribed by
the governmental authority.

                      ARTICLE 11 - Damage and Destruction

     1.  In the event of damage or destruction to all or part of the Demised
Premises or Building by fire or other casualty (collectively, a "casualty"), or
if Tenant's access ("Access") to or use and occupancy of the Building, Demised
Premises, parking area or Common Areas of the Property is interfered with due to
a casualty, Tenant shall notify Landlord thereof as soon as possible after
Tenant becomes aware thereof.

     2.  Landlord or Landlord's managing agent shall have a period of thirty
(30) calendar days from receipt of Tenant's notice pursuant to the first
paragraph of this Article to give Tenant a good faith estimate ("Estimate") of
the time required to repair the casualty and restore Access and/or Tenant's use
and occupancy of the Building, Common Areas, and the Demised Premises to their
condition existing immediately prior to the Casualty. The Estimate shall be
based on the following information, if available: Landlord's own estimate, at
least one independent contractor, and a report from the insurance adjuster
representing the insurance company insuring the Property. If the Estimate is for
a period equal to or more than ninety (90) days, the Casualty is hereby deemed
substantial. If the Estimate is for a period of less than ninety (90) days, the
Casualty is hereby deemed partial.

     3.  If the Demised Premises, or the Building, suffers a partial Casualty
and Tenant's use and occupancy of the Demised Premises and/or Access can be
restored within ninety (90) days, Landlord shall completely repair and restore
same. If Landlord does not substantially complete the repair and restoration
within the Estimate period plus ten (10) days (measured from the date of
Tenant's receipt of the Estimate), Tenant has the right to terminate this Lease
on ten (10) days written notice to Landlord provided that any delay in the
completion of the work on the
<PAGE>
 
                                      25

part of Landlord must be within Landlord's control, or 40 days written notice if
such delay is not within Landlord's control.

     4. If there is a substantial Casualty to the Demised Premises, the
Building, or the Access and Tenant's use and occupancy cannot be restored within
ninety (90) days, either Landlord or Tenant has the right to terminate this
Lease on ten (10) days written notice to Landlord after Tenant's receipt of the
Estimate. If neither party terminates this Lease, then Landlord shall proceed to
promptly repair and restore such damage, destruction or hindrance to Access.

     5.  From the date of such partial or substantial Casualty, a proportionate
part of the Base Rent and Additional Rent, according to the nature and extent of
the interference with Tenant's use and occupancy of or Access to the Demised
Premises shall be equitably abated until the repair and restoration have
occurred. In the event this Lease is terminated as hereunder provided, Tenant
shall pay the Base Rent and Additional Rent prorated to the date of such partial
or substantial Casualty and thereafter, Tenant shall be relieved of all further
liability for the payment thereof.

     6.  Notwithstanding anything to the contrary in this Lease, if the Estimate
is for a period extending beyond the remainder of the Term, either Landlord or
Tenant may terminate this Lease upon ten (10) days written notice to the other,
provided, however, that Landlord may not exercise this right if Tenant has
previously exercised or provides immediate exercise of the extension option
contained in this Lease and within the prescribed time frame defined in Article
3.2 above.

     7.  In the event that the Demised Premises or the Building suffers either
partial or substantial Casualty, the parties have not exercised their respective
rights to terminate this Lease, and Landlord has proceeded to repair and restore
the damage or destruction caused by a Casualty at its own cost and expense, then
Landlord shall be entitled to recover the cost of the repair and restoration
from the following sources:

     (a) The insurance proceeds up to the limit of coverage.

     (b) Any cost not covered by insurance including costs resulting from a
         shortfall in insurance coverage and/or the cost of any deductibles
         shall be the responsibility of the party deemed to be at fault, either
         by a willful or negligent act, as determined in the appropriate
         judicial forum.

                           ARTICLE 12 - Condemnation

     1.  In the event of a taking by condemnation or by the exercise of the
power of eminent domain by a public or quasi-public authority or entity or
conveyance in lieu thereof (all hereinafter referred to as "Taking") of the
entire Demised Premises, or of the entire Building or of the entire parking area
serving the Building, or of the entire Access thereto, either by fee title or
easement, either party may terminate this Lease by giving written notice to the
other party, and this Lease shall terminate on the date that title vests in the
Taking authority or that such Taking
<PAGE>
 
                                      26

authority takes physical possession so as to deprive Tenant of the use thereof
without the necessity for any further act or notice by either party hereto.

     2.  In the event of a partial taking of the Demised Premises, the Building,
the parking area serving the Building, or the Access thereto, either by fee
title or easement, that, in Tenant's judgment reasonably exercised, results in a
material interference in the conduct of Tenant's business operations, Tenant
shall have the right to terminate this Lease upon written notice to Landlord
within thirty (30) days of the Taking. The effective date of the termination
shall be the later of the Taking or fifteen (15) days after the date of such
notice.

         Notwithstanding the foregoing, if the parking area serving the
Building is the subject of the Taking resulting in a reduction of the number of
parking spaces available to Tenant, Landlord may suspend the effectiveness of
such notice by giving its own notice to Tenant within ten (10) days of receipt
of Tenant's termination notice that Landlord shall provide substitute parking
spaces equal to the number taken with sixty (60) days of the Taking.

     3.  In the event this Lease is not terminated as a result of a Taking: (i)
Base Rent and Additional Rent payable hereunder shall abate from the earlier
date of vesting of title or the date of possession by such Taking authority
whether or not there is divestiture of title; such abatement of Base Rent and
Additional Rent shall be in proportion to the amount of the Demised Premises or
Building or Property subject to a Taking and shall be permanent in the case of
divestiture of title; and there shall be no abatement of Base Rent and
Additional Rent for the Taking of parking spaces; and (ii) Landlord shall
commence the work of repairing and restoring the Building to a complete
architectural unit and useable by Tenant as allowed under this Lease, the work
of restoring the remainder of the Demised Premises as nearly as possible to
their condition existing immediately prior to the Taking, and to restore Access
to the Building and Demised Premises or provide alternative Access thereto, all
such work to be commenced within thirty (30) days of possession by the Taking
authority and completed within ninety (90) days ("Work Date") of the effective
date of such possession. If Landlord does not substantially complete the repair
and restoration within the time herein provided, Tenant has the right to
terminate this Lease by giving notice to Landlord within fifteen (15) days of
the Work Date effective on the date specified in the notice, which date shall
not be more that fifteen (15) days from the date of the notice to Landlord
provided that any delay in the completion of the work, on the part of Landlord
must be within Landlord's control.

     4.  In the event of a Taking, Tenant shall, within ten (10) days of the
effective date of the termination of this Lease or the effective date of the
abatement of Base Rent and Additional Rent, as the case may be, receive a refund
from Landlord of the appropriate Base Rent and Additional Rent amount paid by
Tenant prior to the effective date of termination or abatement for any period
subsequent to the effective date of termination or abatement.

                         ARTICLE 32 - Expansion Right

     In addition to the rights and obligations set forth in Section 33.2,

and that Tenant shall have the option to lease (the "Expansion Right") all or a
portion of Building No.1 at the Building Complex, on the terms and subject to
the conditions set forth below in (a) and (b).

     (a) If Tenant wishes to lease all or a portion of Building No. 1 during the
first lease year of the Primary Term, it shall give to Landlord written notice
of the exercise of such option, specifying the area to be leased and the date of
occupancy and Landlord shall deliver such space to Tenant on such date free of
all occupants and personal property, in good basic operating condition and
repair (including a roof airtight and free of leaks), broom clean and in
compliance with applicable building, life and safety codes. From and after the
date of such delivery, (i) such space shall be added to the Demised Premises for
the balance of such lease year, (ii) the Base Rent shall be due with respect to
such space at the rate of $4.75 per square foot per annum for such space, and
(iii) Tenant's Proportionate Share shall increase accordingly. Tenant may
exercise its option to add additional portions of Building No. 1 to the Demised
Premises by sending additional written notices of the exercise of its option to
Lease at any time during the first lease year, and the terms of the prior two
sentences shall apply to such additional space.

     (b) In addition to the Expansion Right set forth in Paragraph (a) above,
Tenant shall have the option to lease all of Building No. 1 for a period
beginning on or before the second lease year of the Term and continuing for the
remainder of the Primary Term and any Extended Term with Base Rent for such
space due at the same rate per square foot per annum for 21,189 square feet, as
shall apply to the Initial Premises pursuant to Article 4. If Tenant wishes to
elect such option, it shall do so by giving written to Landlord written notice
of the election of such option on or before March 31, 1999. In such event,
Building No. 1 shall be delivered to Tenant free of all occupants and personal
property, in good basic operating condition and repair (including a roof
airtight and free of leaks), broom clean and in compliance with applicable
building, life and
<PAGE>
 
                                      39

safety codes, whereupon such space shall be added to the Demised Premises, and
the provisions of Subsections (4)(a)(i) and (iii) shall apply to such space. If
no such notice is timely given, Tenant shall vacate any portion of Building 
No. 1 occupied by it pursuant to Subparagraph (a) above, on or before March 31,
1999 and all rights of Tenant with respect to the leasing of Building No. 1
pursuant to this Section 32 shall terminate and be of no further force and
effect and Landlord shall be free to advertise, market, show or offer Building
No. 1 for lease, subject to the provisions of Section 33.2.

                      ARTICLE 33 - Additional Provisions

    1.  At any time within six (6) months before the expiration of the Term,
Tenant shall at all reasonable times and upon reasonable advance notice permit
Landlord or its agents to enter the Demised Premises to show the Demised
Premises to others, and to affix to any suitable part of the Building and/or the
Demised Premises, but not so as to interfere unreasonably with any of the signs
or the windows of the Tenant, a notice for letting or selling the Demised
Premises, and to keep the same so affixed without hindrance or molestation by
the Tenant.

    2.  Landlord shall provide Tenant with a notification of vacant space, as
space becomes available, or of space to be vacated, as Landlord becomes aware of
such potential available space, in either the existing Building Complex or in
buildings to be constructed on the Land or on adjacent lots. If Tenant does not
exercise its Expansion Right pursuant to Article 32, then Landlord shall be
required to send a notification under this Section 33.2 as to space in Building
No. 1 only after the initial leasing of such space. If Tenant is interested in
the space, then it must notify Landlord in writing within ten (10) days after
receipt of Landlord's notice that it wants to receive a proposal that would
reflect the terms and conditions of a lease that would be acceptable to the
Landlord at that time. Any rent for such space shall be at fair market rates.
The parties shall either mutually agree to a set of terms and condition within
fifteen (15) days after Tenant has received Landlord's proposal or Landlord
shall commence marketing of the space. Landlord's willingness to notify Tenant
of any vacant space pursuant to this Section 33.2 shall not be construed or
implied to mean that Tenant has either a "Right of First Option" or "Right of
First Refusal" on any space that may become vacant during the Term of Tenant's
Lease, except as set forth in Article 32.

    3.  The covenants and agreement herein contained shall, subject to the
provisions hereof, bind and inure to the benefit of Landlord and its successors
and assigns, and Tenant and its successors and assigns, and no extensions,
modifications or change in the terms of this Lease effected with any successor,
assignee or transferee shall cancel or affect the obligations of the original
parties hereto. No officer, director, shareholder, trustee, or beneficiary of
Landlord or Tenant shall be personally liable hereunder. Each party represents
to the other that the person signing this Lease on its behalf is properly
authorized to do so.

    4.  If any provision of this Lease shall be determined to be invalid or
unenforceable by any court of competent jurisdiction in the Commonwealth of
Massachusetts, then such determination shall not affect any other provision of
this Lease, all of which other provisions shall remain in full force and effect;
and it is the intention of the parties hereto that if any
<PAGE>
 
                                      40

provision of this Lease is capable of two constructions, one of which would
render the provision void, and the other of which would render the provision
valid, then the provision shall have the meaning which renders it valid.

    5.  This Lease contains the entire and only agreement between the parties as
to the Demised Premises, and no oral statements or representations or prior
written matter not contained in this instrument shall have any force or effect.
This Lease shall not be modified or canceled except by a writing signed by
Landlord and Tenant.

    6.  This Lease shall be governed by, interpreted and enforced in accordance
with the laws of the Commonwealth of Massachusetts.

    7.  Failure of one party to complain of any act or omission by the other, no
matter how long the same may continue, shall not be deemed to be a waiver of any
rights hereunder. No waiver of any breach of this Lease shall be deemed a
consent to a subsequent breach. All waivers shall be in writing. The consent to
one action given on one occasion shall not be deemed a consent to of the same
action on another occasion. No consent or approval required under this Lease
shall be unreasonably withheld.

    8.  Any and all rights and remedies which either party may have under this
Lease or by operation of law, upon any breach, shall be distinct, separate and
cumulative and shall not be deemed inconsistent with each other; no one of them

                                   RECITALS:

     A.   Lender has made a loan to "Landlord" (defined below) in the amount of

     C.   Tenant is the holder of a leasehold estate in a portion of the
Property under and pursuant to the provisions of a certain lease dated May 29,
1998 as amended September 28, 1998 between Maynard Industrial Properties

     For good and valuable consideration, Tenant and Lender agree as follows:

     1.   SUBORDINATION. Subject to the provisions of Section 2 and 3 below, the
          -------------
Lease and all of the terms, covenants and provisions thereof and all rights,
remedies and options of Tenant thereunder are and shall at all times continue to
be subject and subordinate in all respects to the terms, covenants and
provisions of the Mortgage and to the lien thereof, including without
limitation, all renewals, increases, modifications, spreaders, consolidations,
replacements and extensions thereof and to all sums secured thereby and advances
made thereunder with the same force and effect as if the Mortgage had been
executed, delivered and recorded prior to the execution and delivery of the
Lease.

                                      -2-
<PAGE>
 
     2.  NON-DISTURBANCE. If any action or proceeding is commenced by Lender for
         ---------------    
the foreclosure of the Mortgage or the sale of the Property or to enforce
Lender's rights against Landlord under the Mortgage or the Note or other
obligations secured thereby, Tenant shall not be named as a party therein unless
such joinder shall be required by law, provided, however, such joinder shall
not, nor shall any (i) suit, action, or proceeding upon the Mortgage or the Note
or other obligation secured thereby, (ii) the foreclosure of the Mortgage, (iii)
the enforcement of any rights under the Mortgage, (iv) any other document held
by the Lender, (v) any judicial sale or execution or other sale of the Property

result in the termination of the Lease or disturb the Tenant's possession or use
of the Demised Premises demised thereunder, and the sale of the Property in any
such action or proceeding and the exercise by Lender of any of its other rights
under the Note or the Mortgage shall be made subject to all rights of Tenant and
obligations of Landlord under the Lease, provided that at the time of the
commencement of any such action or proceeding or at the time of any such sale or
exercise of any such other rights (a) the term of the Lease shall have commenced
pursuant to the provisions thereof, (b) Tenant shall be in possession of the
premises demised under the Lease, (c) the Lease shall be in full force and
effect and (d) Tenant shall not be in default past applicable grace or cure

         -------------------------- 
of the Property shall take possession, collect rent, or become the owner of the
Property

<PAGE>
 
by reason of the foreclosure of the Mortgage or the acceptance of a deed or
assignment in lieu of foreclosure or by reason of any other enforcement of the
Mortgage or otherwise (Lender or such other purchaser being hereinafter referred
as "Purchaser"), and the conditions set forth in Section 2(a)-(d) above have
been met, the Lease shall not be terminated or affected thereby but shall
continue in full force and effect as a direct lease between Purchaser and Tenant
upon all of the terms, covenants and conditions set forth in the Lease and in
that event, Tenant agrees to attorn to Purchaser and Purchaser by virtue of such
acquisition of the Property, possession or collection of rent, shall be deemed
to have agreed to accept such attornment, provided, however, that Purchaser
shall not be (a) liable for the failure of any prior landlord (any such prior
landlord, including Landlord and any successor landlord, being hereinafter
referred to as a "Prior Landlord") to perform any of its obligations under the
Lease which have accrued prior to the date on which Purchaser shall become the
owner of the Property, provided that the foregoing shall not limit Purchaser's
obligations under the Lease to correct any conditions that (i) existed as of the
date Purchaser shall become the owner of the Property and (ii) violate
Purchaser's obligations as landlord under the Lease; provided further, however,
that Purchaser shall have received written notice of such omissions, conditions
or violations and has had a reasonable opportunity to cure the same, all
pursuant to the terms and conditions of the Lease, (b) subject to any offsets,
defenses, abatements or counterclaims which shall have accrued in favor of
Tenant against any Prior Landlord prior to the date upon which Purchaser shall
become the owner of the Property, (c) liable for the return of rental security
deposits, if any, paid by Tenant to any Prior Landlord in accordance with the
Lease unless such sums are actually received by Purchaser, (d) bound by any
payment of rents, additional rents or other sums which Tenant may have paid more
than one (1) month in advance to any Prior Landlord unless (i) such sums are
actually received by

                                      -4-
<PAGE>
 
Purchaser or (ii) such prepayment shall have been expressly approved of by
Purchaser or (e) bound by any agreement terminating (unless pursuant to a
termination right under the Lease) or amending or modifying the rent, term,
commencement date or other material term of the Lease, or by any voluntary
surrender of the premises demised under the Lease, made without Lender's or
Purchaser's prior written consent prior to the time Purchaser succeeded to
Landlord's interest. In the event that any liability of Purchaser does arise
pursuant to this Agreement, such liability shall be limited and restricted to
Purchaser's interest in the Property and shall in no event exceed such interest.

     Lender agrees that, in the event of damage or destruction to the Premises
by casualty, Lender will not unreasonably withhold its consent to a request by
Landlord to advance insurance proceeds for restoration of the Premises provided,
however, the following conditions are met:

      (a) Landlord shall not be in default past applicable notice and grace
          periods under the Note or the Mortgage or any documents securing or
          given in connection with the Note (the "Loan Documents");

      (b) Tenant shall not be in default under the Lease beyond applicable
          notice and grace periods;

      (c) The insurance proceeds are in the opinion of Lender sufficient to
          restore the property or, if the proceeds are not sufficient, Landlord
          has deposited with Lender the amount of any such insufficiency;

      (d) The Premises may be restored as a matter of right under applicable law
          and Landlord has secured all permits therefore;

                                      -5-
<PAGE>
 
     (e)  Tenant shall not be entitled to terminate the Lease on account of said
          casualty, or if such termination right exists, Tenant has waived the
          same;

     (f)  The insurance proceeds will be held by Lender and will be advanced
          under Lender's customary construction loan procedures; and

     (g)  The damage or destruction does not occur within the last two years of
          the term of the Lease unless the Lease has been extended.

     Lender acknowledges and agrees that all trade fixtures, equipment and other
property owned by the Tenant located or installed in or on the Demised Premises,
regardless of the manner or mode of attachment, shall be and remain the property
of Tenant and may be removed by Tenant at any time according to the provisions
of Articles 9, 16, and 27 of the Lease

     4.   NOTICE TO TENANT. After notice is given to Tenant by Lender that the
          ----------------
Landlord is in default under the Note and the Mortgage and that the rentals
under the Lease should be paid to Lender pursuant to the terms of the assignment
of leases and rents executed and delivered by Landlord to Lender in connection
therewith, Tenant shall thereafter pay to Lender or as directed by the Lender,
all rentals and all other monies due or to become due to Landlord under the
Lease and Landlord hereby expressly authorizes Tenant to make such payments to
Lender and hereby releases and discharges Tenant from any liability to Landlord
on account of any such payments.

provisions of the Lease to the contrary, no notice of cancellation thereof or of
an abatement shall be effective unless Lender shall have received notice of
default giving rise to such cancellation or abatement and shall have failed
within sixty (60) days after receipt of such notice to cure such default, or if

                                      -6-

such default cannot be cured within sixty (60) days, shall have failed within
sixty (60) days after receipt of such notice to commence and thereafter

Notwithstanding the foregoing, Lender shall have no obligation to cure any such
default.

2.  PROVISIONS CONSTITUTING SUBLEASE

Except to the extent that this Sublease clearly indicates otherwise, all terms
and conditions of the Master Lease and all riders and amendments thereto which
are initialed by both parties are incorporated into and made a part of this
Sublease as if Sublessor were the Landlord thereunder, Sublessee the Lessee
thereunder, and the Premises the Master Premises, except for the following terms
and conditions: In the body of the Master Lease, Articles: 1, 2 (a) (e) (f), 17,
33, 35 (f) (g) (n), 36, 37, 39, Exhibits "B", "C", "E", "H".

Sublessee hereby assumes and agrees to perform the Lessee's obligations under
the Master Lease during the Term to the extent that such obligations are
applicable to the Premises as defined in article 3 hereof. Without limiting the
foregoing, Sublessee shall name Sublessor and Landlord as additional insureds
under the insurance policies required to be carried by Sublessee pursuant to the
incorporation of the insurance paragraphs of the Master Lease. Sublessee shall
not commit or suffer any act or omission that will violate any of the provisions
of the Master Lease. Notwithstanding the foregoing or anything to the contrary

be obligated to perform any of the obligations or to supply or render any of the
services in the Master Lease required to be performed, supplied or rendered by
Landlord. Sublessee shall look solely to the Landlord for the performance for
any of the foregoing obligations and services so long as Sublessor is not in

thereof to the extent Sublessor is responsible under the Master Lease ;
provided, however, unless requested by Landlord, all requests by Sublessee for
the performance of any of the foregoing matters shall be submitted to Landlord

be relieved of any further liability or obligation under this Sublease, provided
however, that if the Master Lease terminates as a result of a default or breach
by Sublessee under this Sublease and/or the Master Lease, Sublessee shall be
liable to the Sublessor for the damage suffered as a result of such termination.
Notwithstanding the foregoing, if the Master Lease gives Sublessor any right to
terminate the Master Lease in the event of the partial or total damage,
destruction, or condemnation of the Master Premises or the building or project
of which the Master Premises are a part, the exercise of such right by Sublessor
shall not constitute a default or breach hereunder.

                                       3
<PAGE>
 
The amount of Base NNN Rental payable by Sublessee under this Sublease shall be
adjusted and increased as of the first day of the thirteenth (13/th/) Sublease
month and on the first day every thirteenth (13/th/) Sublease month thereafter
(the "Adjustment Dates") on the basis of increases in the United States
Department of Labor, Bureau of Labor  Statistics, Consumer Price Index, All
Items, All Urban Consumers for the San Francisco-Oakland-San Jose Region (1982-
1984 = 100), (the "Index"). The Index for the month in which the thirtieth
(30/th/) day preceding each Adjustment Date falls shall be deemed the
"Adjustment Index". The Adjustment Index for determining an adjustment to the
Base NNN Rental for a specific Adjustment Date shall be deemed the Index on the
next following Adjustment Date. At the Adjustment Date, the new Base NNN Rental
shall be determined by multiplying the then current Base NNN Rental by the
percentage increase of the Adjustment Index over the Index; provided, however,
that in no event shall the Base NNN Rental as so adjusted be less than 103% nor

Adjustment Date and Sublessee shall pay the arrears within fifteen (15) days

government agency as may then be in existence which is most nearly equivalent
thereto.

interest bearing security for performance under this Sublease. If Sublessee
fails to pay rent or other charges due hereunder, or otherwise defaults with
respect to any provision of the lease, Sublessor may use, apply or retain all or
any portion of said deposit for the payment of any rent or other charge in
default for the payment of any other sum to which Sublessor may become obligated
by reason of Sublessee's default, or to compensate Sublessor for any loss or
damage which Sublessor may suffer thereby. If Sublessor so uses or applies all
or any portion of said deposit, Sublessee shall within ten (10) days after
written demand therefor, deposit cash with Sublessor in an amount sufficient to
restore said deposit to the full amount required under this Sublease. In any
event, the full amount of the security deposit shall be retained by Sublessor
for the full Term hereof and within thirty (30) days following Sublessee's

to beneficiary. The letter of credit shall be for a minimum period of two years
Sublessor shall have the right to draw (in whole or in part) on the Letter of
Credit any time it would otherwise have the right to apply all or any portion of
the Security Deposit under the terms of the Sublease. However, the Letter of
Credit shall provide that it may be drawn by Sublessor (or assignee) upon
presentation by Sublessor to the issuing bank (at its offices in San Francisco

provided, however, that if the default cannot by its nature be cured within the
twenty (20) day period or cannot after diligent attempts by Borrower be cured

within a reasonable time, then Borrower shall have an additional reasonable
period (which shall not in any case exceed thirty (30) days) to attempt to cure

such default shall not be deemed an Event of Default (provided that no Advances
will be required to be made during such cure period);

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

after Borrower receives notice thereof, provided that none of the foregoing
shall constitute an Event of Default where such action or event is stayed or an
adequate bond has been posted pending a good faith contest by Borrower (provided
that no Credit Extensions will be required to be made during such cure period);

     8.5  Insolvency.  If Borrower becomes Insolvent, or if an Insolvency

9.   BANK'S RIGHTS AND REMEDIES
     --------------------------

     9.1  Rights and Remedies.  Upon the occurrence and during the continuance
          -------------------                                                 
of an Event of Default, Bank may, at its election, without notice of its
election and without demand, do any one or more of the following, all of which
are authorized by Borrower:

          (a) Declare all Obligations, whether evidenced by this Agreement, by
     any of the other Loan Documents, or otherwise, immediately due and payable
     (provided that upon the occurrence of an Event of Default described in
     Section 8.5 all Obligations shall become immediately due and payable
     without any action by Bank);

          (b) Cease advancing money or extending credit to or for the benefit of
     Borrower under this Agreement or under any other agreement between Borrower
     and Bank;

          (c) Settle or adjust disputes and claims directly with account debtors
     for amounts, upon terms and in whatever order that Bank reasonably
     considers advisable;

          (d) Without notice to or demand upon Borrower, make such payments and
     do such acts as Bank considers necessary or reasonable to protect its
     security interest in the Collateral.  Borrower agrees to assemble the
     Collateral if Bank so requires, and to make the Collateral available to
     Bank as Bank may reasonably designate.  Borrower authorizes Bank to enter
     the premises where the Collateral is located, to take and maintain
     possession of the Collateral, or any part of it, and to pay, purchase,
     contest, or compromise any encumbrance, charge, or lien which in Bank's
     determination appears to be prior or superior to its security interest and
     to pay all expenses incurred in connection therewith.  With respect to any
     of Borrower's premises, Borrower hereby grants Bank a license to enter such
     premises and to occupy the same, without charge;

          (e) Without notice to Borrower set off and apply to the Obligations
     any and all (i) balances and deposits of Borrower held by Bank, or (ii)
     indebtedness at any time owing to or for the credit or the account of
     Borrower held by Bank;

          (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare
     for sale, advertise for sale, and sell (in the manner provided for herein)
     the Collateral.  Bank is hereby granted a non-exclusive, royalty-free
     license or other right, solely for the purposes of exercising Bank's rights
     hereunder, to use, without charge, Borrower's labels, patents, copyrights,
     mask works, rights of use of any name, trade secrets, trade names,
     trademarks, service marks, and advertising matter, or any property of a
     similar nature, as it pertains to the Collateral, in completing production
     of, advertising for sale, and selling any Collateral and, in connection
     with Bank's exercise of its rights under this Section 9.1, Borrower's
     rights under all licenses and all franchise agreements shall inure to
     Bank's benefit;

          (g) Sell the Collateral at either a public or private sale, or both,
     by way of one or more contracts or transactions, for cash or on terms, in
     such manner and at such places (including Borrower's premises) as Bank
     determines is commercially reasonable, and apply the proceeds thereof to
     the Obligations in whatever manner or order it deems appropriate;

                                     -20-
<PAGE>
 
          (h) Bank may credit bid and purchase at any public sale, or at any
     private sale as permitted by law; and

          (i) Any deficiency that exists after disposition of the Collateral as
     provided above will be paid immediately by Borrower.

          (j) Bank shall have a non-exclusive, royalty-free license to use the
     Intellectual Property Collateral to the extent reasonably necessary to
     permit Bank to exercise its rights and remedies upon the occurrence of an
     Event of Default.

     9.2  Power of Attorney.  Effective only upon the occurrence and during the
          -----------------                                                    
continuance of an Event of Default, Borrower hereby irrevocably appoints Bank
(and any of Bank's designated officers, or employees) as Borrower's true and
lawful attorney to:  (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust disputes
and claims respecting the accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable; (f) to modify, in its
sole discretion, any intellectual property security agreement entered into
between Borrower and Bank without first obtaining Borrower's approval of or
signature to such modification by amending Exhibit A, Exhibit B, Exhibit C, and
Exhibit D, thereof, as appropriate, to include reference to any right, title or
interest in any Copyrights, Patents, Trademarks, Mask Works acquired by Borrower
after the execution hereof or to delete any reference to any right, title or
interest in any Copyrights, Patents, Trademarks, or Mask Works in which Borrower
no longer has or claims any right, title or interest; (g) to file, in its sole
discretion, one or more financing or continuation statements and amendments
thereto, relative to any of the Collateral without the signature of Borrower
where permitted by law; and (h) to transfer the Intellectual Property Collateral
into the name of Bank or a third party to the extent permitted under the
California Uniform Commercial Code provided Bank may exercise such power of
attorney to sign the name of Borrower on any of the documents described in
Section 4.2 regardless of whether an Event of Default has occurred.  The
appointment of Bank as Borrower's attorney in fact, and each and every one of
Bank's rights and powers, being coupled with an interest, is irrevocable until
all of the Obligations have been fully repaid and performed and Bank's
obligation to provide advances hereunder is terminated.

     9.3  Accounts Collection.  Upon the occurrence and during the continuance
          -------------------                                                 
of an Event of Default, Bank may notify any Person owing funds to Borrower of
Bank's security interest in such funds and verify the amount of such Account.
Borrower shall collect all amounts owing to Borrower for Bank, receive in trust
all payments as Bank's trustee, and if requested or required by Bank,
immediately deliver such payments to Bank in their original form as received
from the account debtor, with proper endorsements for deposit.

     9.4  Bank Expenses.  If Borrower fails to pay any amounts or furnish any
          -------------                                                      
required proof of payment due to third persons or entities, as required under
the terms of this Agreement, then Bank may do any or all of the following:  (a)
make payment of the same or any part thereof; (b) set up such reserves under the
Committed Revolving Line as Bank deems necessary to protect Bank from the
exposure created by such failure; or (c) obtain and maintain insurance policies
of the type discussed in Section 6.6 of this Agreement, and take any action with
respect to such policies as Bank deems prudent.  Any amounts so paid or
deposited by Bank shall constitute Bank Expenses, shall be immediately due and
payable, and shall bear interest at the then applicable rate hereinabove
provided, and shall be secured by the Collateral.  Any payments made by Bank
shall not constitute an agreement by Bank to make similar payments in the future
or a waiver by Bank of any Event of Default under this Agreement.

     9.5  Bank's Liability for Collateral.  So long as Bank complies with
          -------------------------------                                
reasonable banking practices, Bank shall not in any way or manner be liable or
responsible, unless the same is due to Bank's gross negligence or willful

                                     -21-
<PAGE>
 
misconduct, for:  (a) the safekeeping of the Collateral; (b) any loss or damage
thereto occurring or arising in any manner or fashion from any cause; (c) any
diminution in the value thereof; or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever.  All risk
of loss, damage or destruction of the Collateral, unless the same is due to
