corporation.

                                      IMSI

        We are a provider of productivity software for growing businesses. We
distribute our products in more than 60 countries and in 13 languages via
retail, direct, and on-line channels. Since our founding in 1982, we have sold
more than ten million units worldwide. We offer a broad spectrum of
award-winning solutions for growing businesses in the computer-aided design
("CAD"), business applications, visual content and utilities categories. Our
headquarters are located in California and we have offices in Canada, France,
Germany, Australia, South Africa, Sweden, Japan and the United Kingdom.

                                  RISK FACTORS

        Please carefully consider the specific factors set forth below as well
as the other information contained in, or incorporated by reference into, this
prospectus before purchasing shares of our common stock. This prospectus
contains forward-looking statements that involve risks and uncertainties. Our
actual results may differ significantly from the results discussed in the
forward-looking statements. Factors that might cause such a difference include,
but are not limited to, those discussed below.

WE EXPECT A LARGE LOSS IN THE FISCAL YEAR ENDED JUNE 30, 1999.

        We anticipate that IMSI will have a net loss for its fourth fiscal
quarter ending June 30, 1999 and will have a net loss for the entire fiscal
year. Results for Fiscal 2000 will be affected by, among other factors, the
timing and the number of new product releases or upgraded versions of existing
products, as well as marketing and promotional expenditures in connection with
the product releases and the timing of product announcements or introductions by
our competitors.


WE ARE IN NEGOTIATIONS REGARDING OUR BANK LINE OF CREDIT UNDER WHICH CERTAIN
EVENTS OF DEFAULT HAVE OCCURRED.

        IMSI has a line of credit agreement with Union Bank under which it can
borrow the lesser of $13,500,000 or 80% of eligible accounts receivable, at
Union Bank's reference rate plus 1/2 % or LIBOR plus 2%, at IMSI's option. The
line of credit agreement requires IMSI to comply with certain financial
covenants including maintenance of net worth and working capital requirements.
Under the terms of the agreement, all assets not subject to liens of other
financial institutions have been pledged as collateral against the line of
credit. The credit line expires October 31, 1999.



                                       2
<PAGE>   4



        As a result of covenant violations, certain events of default have
occurred that, among other things, entitle Union Bank to declare all loans and
other obligations of IMSI under the line of credit to be immediately due and
payable and to commence immediate enforcement and collection actions, except for
the agreements described in the next paragraph.

        On March 5, 1999, IMSI and Union Bank executed a forbearance agreement,
whereby IMSI agreed to pay down the amount by which IMSI's obligations to Union
Bank exceeded the sum permitted to be borrowed in accordance with the agreement
such that the remaining over-advance did not exceed $2,250,000. IMSI accordingly
paid approximately $1,773,000 of the balance outstanding on the line of credit
in March 1999. Union Bank agreed to forbear taking any enforcement actions until
April 5, 1999. IMSI and Union Bank recently entered into agreements amending the
credit agreement and related instruments. Subject to IMSI's compliance with the
amendment agreements, Union Bank waived IMSI's compliance with certain of the
covenants contained in the credit agreements with respect to our third and
fourth quarters of fiscal 1999, subject to certain conditions including payments
by us to reduce our outstanding balance under the credit facility by at least
$1,800,000. We used a portion of the proceeds that we received from the BayStar
financing described in the next paragraph below to make this payment. If we
breach the provisions of the credit agreements as amended or violate one or more
of the covenants in the amended agreements, Union Bank could declare all loans
and the obligations under the agreements to be immediately due and payable and
could commence immediate enforcement and collection actions, which could have a
material adverse effect on IMSI's business, operating results and financial
condition.

WE NEED TO RAISE ADDITIONAL FUNDS.

        On May 26, 1999, we announced that we completed a private placement
transaction (the "BayStar Financing") in which we received $5,000,000 from
BayStar Capital and we issued to BayStar a three-year $5,000,000 principal
amount 9% subordinated convertible note, and a warrant to acquire 250,000 shares
of common stock at an initial exercise price of $7.59 per share. The note is
convertible into shares of common stock at an initial conversion price of $7.59
per share. The note and warrant contain various anti-dilution and other
provisions which could, depending upon the occurrence of certain events
including the market price of the common stock at future dates and the terms of
certain kinds of future equity financing transactions, result in additional
shares being issuable upon conversion of the note or exercise of the warrant.
Even with the proceeds from the BayStar Financing, we currently anticipate that
the available funds and cash flows generated from operations will not be
sufficient to meet our anticipated needs for working capital and capital
expenditures for the next 12 months. Therefore, we will need to raise additional
funds i the near future. As a result of our need for funds and our substantial
losses during fiscal 1999 to date, during fiscal 1999 we instituted measures to
improve operations and cash flows, including substantial personnel reductions
and the initiation of certain cost cutting programs, and we may take further
measures, including further personnel reductions, during fiscal 1999 and
thereafter. We will need to raise significant new working capital through
additional debt or equity financing in order to sustain our operations and fund
our operating plans, and to fund business expansion, develop new or enhanced
products, respond to competitive pressures or acquire complementary products,
businesses or technologies. If we successfully raise additional funds, it is
likely that they will be raised through the issuance of equity or convertible
debt securities, and thus the percentage of ownership of the stockholders will
be reduced, stockholders will experience additional dilution and such securities
may have rights, preferences or privileges senior to those of the holders of our
common stock.

        We cannot provide any assurance that additional financing will be
available on terms favorable to us, or at all. If adequate funds are not
available or are not available on acceptable terms, we may not be able to fund
expansion, take advantage of unanticipated acquisition opportunities, develop or
enhance services or products or respond to competitive pressures. In addition,
such inability could have a material adverse effect on our business, operating
results and financial condition.

        Our financial statements have been prepared on a going concern basis,
which contemplates the realization of assets and satisfaction of liabilities in
the normal course of business. The losses discussed above, and other factors
such as our liquidity, raise questions concerning our ability to continue as a
going concern. Our financial statements do not include any adjustments relating
to the recoverability and classification of recorded asset amounts or the
amounts and classification of liabilities that might be necessary should we be
unable to continue as a going concern. Our continuation as a going concern is
dependent upon our ability to obtain additional financing or refinancing, to
generate sufficient cash flow to meet our obligations on a timely basis, and
ultimately to attain successful operations.

OUR PREVIOUS AUDIT FIRM RESIGNED.

        As we reported in a Form 8-K filed on April 26, 1999, Deloitte & Touche,
LLP resigned in April 1999 as our independent auditor. As reported in the Form
8-K filed by IMSI on May 12, 1999, IMSI retained Grant Thornton, LLP as our new
independent auditor.

WE EXPERIENCE FLUCTUATIONS IN OUR OPERATING RESULTS.

        We have experienced, and expect to continue to experience, significant
fluctuations in operating results due to a variety of factors. We experienced
growth during fiscal 1998, 1997, and 1996. However, during fiscal year 1999, we
suffered a significant decline in revenue from $45.6 million in the nine months
ended March 31, 1998 to $30.9 million in the nine months ended March 31, 1999.
This decline in revenue has resulted in our reporting net losses for the first
three quarters of fiscal 1999 with a net loss of $5.4 million in the nine months
ended March 31, 1999, compared with a net loss of $1.9 million in the six months
ended December 31, 1997.

        Factors that may cause fluctuations in operating results in the future
include, but are not limited to,

        -       market acceptance of our products or those of our competitors;

        -       the timing of introductions of new products and new versions of
                existing products;

        -       expenses relating to the development and promotion of such new
                products and new version introductions;

        -       product returns and reserves; changes in pricing policies by us
                or our competitors;

        -       projected and actual changes in platforms and technologies;

        -       the accuracy of forecasts of, and fluctuations in, consumer
                demand;

        -       the extent of third party royalty payments;

        -       the rate of growth of the consumer software market;

        -       fluctuations in foreign exchange rates;

        -       the timing of orders or order cancellation from major customers;

        -       changes or disruptions in the consumer software distribution
                channels;

        -       the successful acquisition and integration of new businesses,
                products and technologies;

        -       the timing of any write-offs in connection with such
                acquisitions; and

        -       economic conditions, both generally and within our industry.

        We may also be required to pay fees in advance or to guarantee
royalties, which may be substantial, or to obtain software licenses from third
parties. As a result of these and other factors, our operating results in any
given period are inherently difficult to predict. Any significant shortfall in
revenues and earnings from the levels expected by securities analysts and
stockholders could result in a substantial decline in the trading price of our
common stock.

        While our business has not generally been materially affected by
seasonal trends, the seasonality of the European, Asia/Pacific and other
international markets could impact our operating results and financial condition
in a particular quarter given the significant portion of net revenues
contributed by international operations. The markets for our products are also
characterized by significant price competition, which may cause our operating
results to fluctuate.

WE ANTICIPATE A SIGNIFICANT RESTRUCTURING CHARGE DURING THE FOURTH QUARTER OF
FISCAL 1999.

        IMSI is in the process of implementing a company-wide restructuring in
response to its fiscal 1999 decline in revenues and net losses. In this regard,
we are attempting to reduce the costs associated with our retail


                                       4
<PAGE>   6

operations, to focus on our strongest product franchises, and to discontinue
investment in non-strategic products. We plan to move to a more variable cost
model and reduce fixed infrastructure. We expect to incur a significant
restructuring charge in the current fourth quarter of fiscal year 1999. This
charge may include write-downs of inventories and other intangible assets
relating to non-strategic products, as well as costs associated with personnel
reductions and facilities closures.

WE MAY NOT BE PROFITABLE IN THE FACE OF RAPIDLY CHANGING TECHNOLOGY.

        The markets for our products are characterized by rapidly changing
technology, frequent new product introductions and uncertainty due to new and
emerging technologies, as well as changes in customer requirements and
preferences. Changes in technologies and customer requirements and preferences,
product obsolescence and advances in computer software and hardware will require
us to develop or acquire new products and to enhance our products in a timely
manner at improved price/performance levels in order to remain competitive. The
pace of change has recently accelerated due to the Internet, corporate
intranets, the introduction of 32-bit operating systems such as Windows 95,
Windows 98 and Windows NT 4.0, and new programming languages, such as Java. PC
hardware, in particular, is steadily advancing in power and function,
facilitating expansion of the market for increasingly complex and flexible
software products. This, in turn, has resulted in escalating development costs,
longer periods necessary for development of new products and a greater degree of
unpredictability in the time necessary to develop products. Due to potential
difficulties in the development process, we cannot provide assurance that future
products and upgrades will be released in a timely manner or that they will
receive market acceptance, if and when released. Despite significant testing by
us and by current and potential customers, errors or "bugs" may still be found
in new products or upgrades after commencement of commercial shipments,
especially when first introduced. Delays in the commencement of commercial
shipments of new products or upgrades, as well as the discovery of errors or
"bugs" after release, may result in adverse publicity, customer dissatisfaction
and delay or loss of product revenues. In addition, such errors or "bugs" could
require significant design modification or corrective releases and could result
in an increase in product returns. Furthermore, from time to time we and others
may announce new products, capabilities or technologies that have the potential
to replace or shorten the life cycles of our existing products. We cannot assure
that announcement of currently planned or other new products by us or by our
competitors will not cause customers to defer purchasing our products existing
or cause distributors to return products to us. In addition, rapid changes in
the market and increasing numbers of new products available to consumers have
increased the degree of consumer acceptance risk with respect to any specific
title that we may publish. We expect that this trend will continue and may
become more pronounced in the future. Consumer preferences are difficult to
predict, and few consumer products achieve sustained market acceptance.

        We cannot provide assurance that we will be successful in our product
development efforts or that we will have the resources required to respond to
technological changes or to compete successfully in the future. Delays or
difficulties associated with new product introductions or upgrades could have a
material adverse effect on our business, operating results and financial
condition. In addition, because we expect that the cost of developing and
introducing new products will continue to increase, the financial risks
associated with new product development will increase as will the risks
associated with material delays in the introduction of such new products. If we
are unable to develop or acquire new products in a timely manner as revenues
decrease from products reaching the end of their natural life cycles, our
operating results will be adversely affected. Because of our small size and
capital resources relative to some of our competitors, our ability to avoid
technological obsolescence through acquisition or development of new products or
upgrades of existing products may be more limited than companies with greater
funds.

WE FACE RISKS IN INITIATING AND EXECUTING OUR INTERNET STRATEGY.

        Our marketplace has recently experienced a higher emphasis on online and
Internet-related services and content tailored for this new delivery vehicle. We
have taken and will continue to take steps, at significant cost, to take
advantage of opportunities created by the Internet and online networks, and we
expect to continue incurring significant additional costs in connection with our
Internet infrastructure. These changes include material and costly additions to
our existing hardware, substantial increase in personnel for experienced web
designers, acquisitions and cross licenses to drive traffic to our web sites and
a transition to an Internet sales and marketing strategy. We cannot provide any
assurance that our Internet strategy will be successful, or that the costs and
investments in this area will



                                       5
<PAGE>   7

provide adequate, or any, results. Delivery of software using online services or
the Internet will necessitate certain changes in our business and operations
including addressing operational challenges such as improving download time for
pictures, images and programs, ensuring proper regulation of content quality and
developing sophisticated security for transmitting payments. Our failure to
adapt to and utilize such technologies and media successfully and in a timely
manner could materially and adversely affect our competitive position and our
financial results.

        IMSI depends to some extent and is increasing its dependence on
relationships with other online companies. These relationships include, but are
not limited to, agreements for anchor tenancy, promotional placements,
sponsorships and banner advertisements. Generally, these agreements have terms
for up to a year, are not exclusive and do not provide for guaranteed renewal.
The risks included in this dependence include:

        (i)     the possibility that a competitor will purchase exclusive rights
                to attractive space on one or more key sites;

        (ii)    the uncertainty that significant spending on these relationships
                will increase IMSI's revenues substantially or at all;

        (iii)   the possibility that potential revenue increases resulting from
                such spending will not occur within the time periods that IMSI
                is expecting;

        (iv)    the possibility that space on web sites may increase in price or
                cease to be available on reasonable terms or at all;

        (v)     the possibility that such online companies will be unable to
                deliver a sufficient number of customer visits or impressions;
                and

        (vi)    the possibility that such online companies will compete with
                IMSI for limited online revenues. Any termination of our
                arrangements with other online companies could have a material
                adverse effect on IMSI's business, results of operations and
                financial condition.

        A key element of our Internet strategy is to generate a high volume of
traffic to, and use of, our Website. IMSI's revenues will depend primarily on
the number of customers who use our Website to purchase merchandise.
Accordingly, the satisfactory performance, reliability and availability of our
Website, transaction-processing systems, network infrastructure and delivery and
shipping systems are critical to IMSI's operating results, as well as to our
reputation and our ability to attract and retain customers and maintain adequate
customer service levels. IMSI periodically has experienced minor systems
interruptions, including Internet disruptions, which it believes may continue to
occur from time to time. Any systems interruptions, including Internet
disruptions, that result in the unavailability of our Website or reduced order
fulfillment performance would reduce the volume of goods sold, which could have
a material adverse effect on IMSI's business, results of operations and
financial condition. IMSI is continually enhancing and expanding its
transaction-processing systems, network infrastructure, delivery and shipping
systems and other technologies to accommodate a substantial increase in the
volume of traffic on IMSI's Website. There can be no assurance that IMSI will be
successful in these efforts or that IMSI will be able to accurately project the
rate or timing of increases, if any, in the use of our Website or timely expand
and upgrade our systems and infrastructure to accommodate such increases. There
can be no assurance that IMSI's or our suppliers' network will be able to timely
achieve or maintain a sufficiently high capacity of data transmission,
especially if the customer usage of our Website increases. IMSI's failure to
achieve or maintain high capacity data transmission could significantly reduce
consumer demand for our services and have a material adverse effect on our
business, results of operations and financial condition.

WE MAY HAVE DIFFICULTIES SUCCESSFULLY INCORPORATING NEWLY ACQUIRED PRODUCTS AND
TECHNOLOGIES INTO OUR BUSINESS.

        We have acquired businesses, technologies, services, product lines
and/or content databases that are complementary to our business in order to
broaden our product lines and geographic sales channels. For example, during the
first quarter of fiscal 1998, we acquired a number of products in the CAD,
diagramming and consumer categories from Corel Corporation; entered into a
technology licensing agreement with Dragon Systems, a developer of speech
recognition products; acquired from Quarterdeck


                                       6
<PAGE>   8

Corporation exclusive worldwide licensing rights to the HiJaak graphics utility
products; acquired certain assets of MediaPaq, Inc., including our browser
technology; and acquired certain assets of MapLinx, Inc., including a mapping
software program. We believe that our future growth will depend, in part, upon
the success of our recent and possible future acquisitions. We cannot provide
assurances that the anticipated benefits of recently concluded business
combinations and product acquisitions will be realized, or that we will be
successful in identifying suitable acquisition opportunities in the future. We
may face increased competition for future acquisition opportunities, which may
inhibit our ability to consummate suitable acquisitions and increase the costs
of completing such acquisitions. Further, we cannot provide assurances that we
will be able successfully to integrate acquired technologies, services, product
lines or businesses. Acquisitions entail a number of risks, including managing a
larger and more geographically disparate business; diversion of management
attention; development of and marketing acquired products to markets with which
we may not be familiar; integrating the acquired products into our product
lines; coordinating diverse operating structures, policies and practices; and
integrating the employees of the acquired companies into our organization and
culture. Our failure to integrate and manage acquired businesses successfully,
to retain our employees and to successfully address new markets associated with
such acquired businesses would have a material adverse effect on our business,
operating results and financial condition. Certain of our acquisitions have
involved issuances of equity securities and resulted in various charges and
expenses that have adversely affected, and will continue to adversely affect,
our operating results and financial condition. Future acquisitions may also
result in potential charges that may adversely affect our earnings and may
involve the issuance of shares of our stock to owners of acquired businesses,
resulting in dilution in the percentage of our stock owned by other
stockholders.

OUR SUCCESS DEPENDS ON KEY PERSONNEL.

        We have recently experienced changes in our board of directors and
management. As previously reported in a press release and in our quarterly
Report on Form 10-Q for the period ended March 31, 1999, IMSI announced the
appointment of Costa John, our Chief Financial Officer, as our Chief Executive
Officer. Mr. John remains the Chief Financial Officer. Martin Sacks, formerly
Chief Executive Officer and President of IMSI, resigned as CEO and President but
remains a director and was elected Chairman of the Board. As part of the
restructuring of the management team and the Board, Geoffrey Koblick, formerly
Chief Operating Officer and Chairman, has retired from both positions and as a
director, but continues to be available as an advisor to IMSI. In addition,
Robert Mayer, who continues as executive Vice President of Worldwide Sales and
Marketing, has resigned as a director.

        Our success depends to a significant extent on the performance and
continued service of our senior management and certain key employees. We
maintain no key person insurance and do not have employment agreements or
non-competition agreements with all of our key employees. Competition for highly
skilled employees with technical, Internet, management, marketing, sales,
product development and other specialized training is intense, and the supply is
limited. In particular, we have historically experienced difficulty in
attracting highly qualified programmers and software engineers in the U.S. We
cannot provide any assurance that we will be successful in attracting,
motivating and retaining such personnel. In addition, we cannot provide any
assurance that one or more key employees will not leave us or compete against
us. Our failure to attract qualified employees or to retain the services of key
personnel could materially adversely affect our business, operating results and
financial condition.

COMPETITION WITHIN DISTRIBUTION CHANNELS MAY ADVERSELY AFFECT OUR BUSINESS.

        The distribution channels through which consumer software products are
sold have been characterized by intense competition and continuing
uncertainties, including consolidations and financial difficulties of certain
distributors and resellers, the emergence of new resellers such as general mass
merchandisers and superstores, the development of new channels such as the
Internet and the desire of large customers such as retail chains and corporate
users to purchase directly from software developers. Competition for access to
distribution channels and for retail shelf space is intense. We have no
long-term distribution agreements with any reseller. We cannot provide any
assurance that our distributors and retailers will continue to purchase our
products or provide our products with adequate levels of shelf space and
promotional support or that we will be able to distribute our products
effectively through new distribution channels. Our distributors and retailers
carry competing product lines, and there is substantial pressure from
distributors and retailers to obtain marketing and promotional funds, price
discounts and favorable return policies in connection with access to shelf
space, in-store promotions and sales of products, which has an adverse impact on
our net revenues and profitability. In addition, consolidation among the



                                       7
<PAGE>   9

companies within our distribution channels has reduced the number of available
distributors, which has increased the competition for shelf-space. We cannot
provide any assurance that these pressures will not continue or increase.

        We allow distributors to return products in exchange for new products or
for credit towards future purchases as part of stock balancing programs. In
addition, we provide price protection to our distributors when we reduce the
price of our products. End users may return products through dealers and
distributors within a reasonable period from the date of purchase for a full
refund, and retailers may return older versions of products. Various
distributors and resellers may have different return policies. Substantial
product returns occur when we introduce upgrades and new versions of products or
when distributors or resellers overestimate demand. We anticipate that product
returns in future periods will continue to be adversely affected by product
update cycles, new product releases and software quality. We establish
allowances based on estimated future returns of products after considering
various factors, and accordingly, if the level of actual returns exceeds our
estimates, it could have a material adverse impact on our operating results and
financial condition. While we attempt to monitor channel inventories and provide
appropriate reserves, actual product returns may differ from our reserve
estimates, and such differences could be material to our operating results and
financial condition.

        We manufacture our products based upon estimated future sales, and
accordingly, if the level of actual orders of products falls short of
management's estimates, inventory levels could be excessive, which could add to
inventory write-offs and have an adverse impact on our business, operating
results and financial condition.

WE DEPEND ON A LIMITED NUMBER OF DISTRIBUTORS AND RETAILERS FOR A SUBSTANTIAL
AMOUNT OF REVENUES.

        Sales to a limited number of distributors and retailers have constituted
and are expected to continue to constitute a substantial amount of our revenues.
Sales to our two largest distributors during the nine months ending on March 31,
1999 accounted for approximately 36% of net revenues for that period. Sales to
our two largest distributors during fiscal 1998 accounted for an aggregate of
35% and 25% of our revenues during fiscal 1997, respectively. Arrangements with
our distributors and retailers may generally be terminated at any time by the
distributor or retailer. While we are currently attempting to negotiate direct
sales relationships with the major retailers, there is no guarantee we will be
able to reduce our reliance on distributors either quickly or at all. The loss
of a significant reduction in sales due to the inability to collect receivables
from, or any other adverse change in our relationship with, any of our principal
distributors or retailers, or principal accounts sold through such distributors,
could materially adversely affect our operating results and financial condition.
In addition, sales of our products are typically made on credit with terms that
vary depending upon the customer and the nature of the product. Our distributors
and retailers compete in a volatile industry and are subject to the risk of
bankruptcy or other business failure, and certain distributors and retailers
have experienced difficulties. Although we maintain a reserve for uncollectible
receivables, we cannot provide any assurance that our reserve will prove to be
sufficient or that the difficulties for these or additional distributors and
retailers will not continue, which could have an adverse effect on our business,
operating results and financial condition.

OUR SUCCESS DEPENDS ON THE SUCCESS OF A FEW PRODUCT LINES.

        During the nine months ended March 31, 1999, 52% of our net revenues
were derived from sales of our business applications, 12% of our net revenues
were derived from sales of our utilities, and 42% of our net revenues were
derived from sales of our visual content products. During fiscal 1998, 43% of
our net revenues were derived from sales of our business applications, 19% of
our net revenues were derived from sales of our utilities, and 29% of our net
revenues were derived from sales of our visual content products. During fiscal
1997, 34% of our net revenues were derived from sales of our business
applications, 11% of our net revenues were derived from sales of our utilities,
and 46% of our net revenues were derived from sales of our visual content
products. Within the business applications category, the products within the
business drawing category (primarily the TurboCAD product line) accounted for
approximately 20% of our net revenues during the nine months ended March 31,
1999, 22% of our net revenues during fiscal 1998, and 20% of our net revenues
during fiscal 1997. Within the visual content category, the MasterClips product
family accounted for approximately 46% of our net revenues during the nine
months ended March 31, 1999, 29% of our net revenues during fiscal 1998, and 46%
of our net revenues during fiscal 1997. These were the leading products in their
respective categories and, although we publish a broad range of products, these
product lines are expected to continue to account for a material percentage of
net revenues in fiscal 1999 and thereafter. Accordingly, our future operating
results will depend, in part, on continued and expanded market acceptance of
these product lines, as well as our ability to continue to enhance these product
lines

                                       8
<PAGE>   10

and to introduce new products. We cannot provide any assurance that sales levels
of any of these families of products will increase or be sustained, especially
in light of increased competition in the marketplace. Any circumstances
adversely affecting sales of these families of products, including such factors
as product life cycles, market acceptance, product performance and reliability,
reputation, price competition and the availability of third-party applications,
could have a material adverse effect on our business, operating results and
financial condition. The failure of new products in these families to achieve
market acceptance could also have a material adverse effect on our business,
operating results and financial condition.

OUR INTELLECTUAL PROPERTY MAY BE VULNERABLE.

        As the number of software products in the industry increases and the
functionality of these products further overlaps, software developers and
publishers may increasingly become subject to infringement claims. From time to
time, we have received, and may receive in the future, notice of claims of
infringement of other parties' proprietary rights. Although we investigate
claims and respond as we deem appropriate, we cannot provide any assurance that
infringement or invalidity claims (or claims for indemnification resulting from
infringement claims) will not be asserted or prosecuted against us. Irrespective
of the validity or the successful assertion of such claims, we would incur
significant costs and diversion of resources with respect to the defense of such
claims, which could have a material adverse effect on our business, operating
results and financial condition. If any valid claims or actions were asserted
against us, we might seek to obtain a license under a third-party's intellectual
property rights. We cannot provide any assurance, however, that under such
circumstances a license would be available on commercially reasonable terms, or
at all.

        We provide our products to end users under non-exclusive licenses, which
generally are non-transferable and have a perpetual term. We make source code
available for certain of our products. The provision of source code may increase
the likelihood of misappropriation or other misuse of our intellectual property.
We license all of our products pursuant to shrink-wrap licenses that are not
signed by licensees and therefore may be unenforceable under the laws of certain
jurisdictions.

OUR MARKETPLACE IS INTENSELY COMPETITIVE AND RAPIDLY CHANGING AND WE MAY NOT BE
ABLE TO COMPETE SUCCESSFULLY IN THE FUTURE.

        The PC productivity software industry is highly competitive and is
characterized by rapid changes in technology and customer requirements.
Important factors in the market include product features and functionality,
quality and performance, reliability, brand recognition, ease of understanding
and operation, advertising and dealer merchandising, access to distribution
channels and retail shelf space, marketing, pricing and availability and quality
of support services. We face competition from a large number of sources. There
has been a consolidation among competitors in the market for our products, and
many of our current and potential competitors have larger technical staffs, more
established and larger marketing and sales organizations, significantly greater
financial resources and greater name recognition and better access to consumers
than we do. Our relatively small size could adversely affect our ability to
compete with larger companies for sales to dealers, distributors and retail
outlets, to obtain shelf space for our products in retail outlets and to acquire
products from third parties, who may desire to have their products sold or
published by larger entities. The rapid pace of technological change constantly
creates new opportunities for existing and new competitors and can quickly
render existing technologies less valuable. It also requires us to enhance our
existing products and to offer new products on a timely basis. We have limited
resources and therefore must restrict our product development efforts to a
relatively small number of projects.

        We compete with other software companies in our efforts to acquire
products or companies and to publish software developed by third parties. The
competition to publish software developed by third parties is primarily on the
basis of brand-name reputation, the terms offered to software developers and the
ability to market new products.

        Each of our major products competes with one or more products from one
or more major independent software vendors. For example:

        -       TurboCAD competes with AutoCAD from Autodesk Inc. and IntelliCAD
                from Visio Corporation.

        -       WinDelete competes with Uninstaller from CyberMedia Inc.,
                CleanSweep and Norton Uninstaller from Symantec Corporation.



                                       9
<PAGE>   11

        -       MasterClips competes with ClickArt from Broderbund Software
                Inc., MegaGallery from Corel Corporation, Holy Cow! from
                Macmillan Digital Publishing USA and Art Explosion from Nova
                Development.

        -       VoiceDirect competes with various speech recognition products
                from IBM, Dragon Systems, Inc., Kurzweil and Lernout & Hauspie.

        -       Net Accelerator competes with SurfExpress from Connectix, Speed
                Surfer from Kissco and Net.jet from Peak Technologies.

        -       FloorPlan competes with Home Architect from Cendant Corporation,
                Home Design Suite from Autodesk, Dream Home Designer from Alpha
                Software Corporation and Home Design 3D from Expert Software,
                Inc.

        -       TurboProject competes with Microsoft Project.

        Our strategy has been to develop productivity and utility applications
that do not compete directly with applications or features included in operating
systems and applications suites offered by major software vendors such as
Microsoft, Lotus Development Corp. and Corel. However, such software vendors may
in the future choose to expand the scope and functionality of their products to
support some or all of the features currently offered by certain of our
products, which could adversely affect demand for our products. In particular,
Microsoft has periodically added utility features (e.g. disk compression
utilities and desk-top facing features) to its Windows operating systems that
were previously only supported by third-party vendors and that materially
reduced demand for third-party utility products. In addition, Microsoft's
Windows 98 contains features for the automatic updating of Windows 98 (including
third party device drivers) and many Microsoft applications via the Internet,
which could adversely impact sales of our Update Now! product. Windows 98 also
contains the latest version of Microsoft's Internet Explorer which handles the
caching of Web pages more efficiently. This feature may adversely impact sales
of our Net Accelerator product family.

        The software industry has limited barriers to entry, and the
availability of personal computers with continuously expanding capabilities, at
progressively lower prices, contributes to the ease of market entry. We believe
that competition in the industry will continue to intensify as a number of
software companies extend their product lines into additional product categories
and as additional competitors enter the market. In addition, widespread use of
the Internet has reduced barriers to entry in the software market by allowing
software developers to distribute their products online without relying on
access to traditional distribution networks. As a result of the proliferation of
competing software developers, an increasingly large number of products are
competing for limited shelf space. There can be no assurance that our products
will achieve and/or sustain market acceptance and generate significant levels of
revenues in subsequent quarters or that we will have the resources required to
compete successfully in the future.

OUR DEPENDENCE ON THIRD PARTY DEVELOPERS COULD HAVE A MATERIAL ADVERSE EFFECT ON
OUR BUSINESS.

        Our business strategy has historically depended in part on our
relationships with third-party developers, who provide products that expand the
functionality of our software. Many of these licenses require payment of
royalties based on the number of products sold. In other cases, we may be
required to pay substantial up-front royalties and development fees to software
developers before the commercial viability of their products has been tested.
Failure of such products to achieve commercial success could result in
substantial charges against our earnings. Licenses from third parties for
several of our products have limited terms and are non-exclusive. We cannot
provide any assurance that these third-party software licenses for current
products or for new products will continue to be available on commercially
reasonable terms, or that the software will be appropriately supported,
maintained or enhanced by the licensors. The loss of licenses to, or the
inability to support, maintain and enhance, any such software, could result in
increased costs, or in delays or reductions in product shipments until
equivalent software could be developed, identified, licensed and integrated,
which would have a material adverse effect on our business, operating results
and financial condition. In addition, because talented development personnel are
in high demand, we cannot provide any assurance that independent developers,
including those who have developed products for us in the past, will be able to
provide development support to us in the future. If sales of software



                                       10
<PAGE>   12

utilizing third-party technology increase disproportionately, operating income
as a percent of revenue may be below historical levels due to third-party
royalty obligations.

THERE ARE RISKS ASSOCIATED WITH OUR USE OF DEVELOPMENT TEAMS OUTSIDE THE UNITED
STATES.

        Most program coding and quality testing of our products are performed
using contract programmers in development centers in various locations in
Russia, Ukraine, India, and several other countries. Although the cost of
programmers outside of the United States is significantly lower than the cost of
programmers available to us domestically, our reliance on such programmers
presents a number of risks. Due to the geographic distance between our
engineering management personnel in California and the contract programmers
overseas, it is more difficult for us to manage, oversee and control the
programming process. In addition, cultural and language differences make
coordination of our United States management and overseas programming efforts
more difficult. While our agreement with the entity through which we compensate
these programmers provides that we own the code developed by the programmers,
the location of the source code outside the United States may make it more
difficult for us to ensure that access to our source code is adequately
restricted. Given our reliance on programmers outside the United States, our
business, operating results and financial condition would be materially
adversely affected if we were to lose the services of these programmers.
Although we would likely be able to locate alternative programmers within the
United States or in other countries to the extent that the overseas programmers
were no longer available, the costs associated with such alternative programmers
could significantly increase our operating expenses.

WE FACE DIFFICULTIES IN MANAGING CHANGE.

        In recent years, we have experienced changes in our operations that have
placed significant demands on our administrative, operational and financial
resources. The growth in our Internet customer base and expansion of our
Internet product families, together with our acquisition of other businesses and
their employees, have challenged and are expected to continue to challenge our
management and operations, including our sales, marketing, customer support,
research and development and finance and administrative operations. In order to
address certain of these challenges, we need to upgrade elements of our
information systems. We cannot provide any assurance that we will successfully
overcome difficulties with such upgrades in a timely manner, which could
adversely affect our ability to continue to manage the growth of our operations.
Our future performance will depend in part on our ability to manage change
successfully, in both our domestic and our international operations, and to
adapt our operational and financial control systems, if necessary, to respond to
changes in our business and to facilitate the integration of acquired businesses
with our operations. The failure of our management to effectively respond to and
manage growth could have a material adverse effect on our business, operating
results and financial condition.

WE FACE RISKS ASSOCIATED WITH OUR INTERNATIONAL OPERATIONS.

        For the nine months ended March 31, 1999, net revenues from
international sales were $9,392,000 or 30% of net revenues. International sales
represented 33% of revenues for the nine months ended March 31, 1999, 30% of our
revenues during fiscal 1998, 41% of our revenues during fiscal 1997. We expect
that international sales will account for an increasing portion of our revenues
in the future. Most of our international revenues are denominated in foreign
currencies. Consequently, a decrease in the value of a relevant foreign currency
in relation to the U.S. dollar can adversely affect our net revenues. Further, a
decrease in the value of a relevant foreign currency in relation to the U.S.
dollar occurring after prices and before receipt of payment by us would have an
adverse effect on our results of operations. Additionally, we may be materially
and adversely affected by increases in duty rates, exchange or price controls,
changes in tariffs, difficulties managing accounts receivable, longer collection
cycles, repatriation restrictions or other restrictions on foreign currencies.
Our international operations are subject to certain other risks common to
international operations, including without limitation, difficulties managing
foreign operations, the timely and successful launch of foreign products,
government regulations, import and export restrictions, changes in international
tax laws, political instability and, in certain jurisdictions, reduced
protection for our intellectual property rights. We have committed and continue
to commit significant time and development resources to customizing certain of
our products for selected international markets and to developing international
sales and support channels. We cannot provide any assurance that our efforts to
develop products for targeted international markets or to develop additional
international sales and support channels will be successful. The failure of such
efforts, which can entail considerable expense, could have a material adverse
effect on our business, operating results and financial condition.



                                       11
<PAGE>   13

        Although IMSI believes that the risks associated with transactions in
foreign currencies are mitigated by diversified exposure to multiple currencies,
IMSI's operating results may be affected by the risks customarily associated
with international operations, including a devaluation of the U.S. dollar,
increases in duty rates, exchange or price controls, longer collection cycles,
government regulations, political instability, and changes in international tax
laws.

WE HAVE EXPERIENCED SIGNIFICANT DILUTION.

        We have issued common stock in connection with strategic acquisitions
and other transactions. As a result, we have experienced common stock dilution.
On June 30, 1998, IMSI had 5.7 million shares issued and outstanding. On March
31, 1999, IMSI had approximately 6.8 million shares issued and outstanding. This
prospectus covers 2,524,823 shares of common stock, of which 1,100,857 shares
are outstanding and 1,423,966 shares may be issuable in the future upon the
occurrence of certain events. IMSI may issue additional shares of common stock
during Fiscal 1999 and thereafter.

DIRECTORS AND OFFICERS BENEFICIALLY OWN A SIGNIFICANT PERCENTAGE OF OUR SHARES.

        As of the date of this prospectus, the present directors and executive
officers of IMSI and their respective affiliates, in the aggregate, beneficially
owned approximately 16% of our outstanding common stock. As a result, these
stockholders will possess significant influence over us. Such influence may have
the effect of delaying or preventing a change in control, impeding a merger,
consolidation, takeover or other business combination involving IMSI or
discouraging a potential acquirer from making a tender offer or otherwise
attempting to obtain control of us.

OUR RELIANCE ON OUTSOURCING COULD MATERIALLY ADVERSELY AFFECT OUR OPERATING
RESULTS.

        We outsource most of the production of our products, which primarily
involves duplication of various media and the printing of user manuals and
packaging materials. So long as it remains economically advantageous to do so,
we intend to continue, and possibly to increase, outsourcing in the future.
Although we believe that we have adequate alternative suppliers of such
services, the loss of a supplier or our inability to perform contract services
could materially adversely affect our operating results.

OUR COMMON STOCK PRICE IS HIGHLY VOLATILE AND IS SUBJECT TO WIDE FLUCTUATIONS.

        The market price of our common stock is highly volatile and could be
subject to wide fluctuations in response to factors such as actual or
anticipated variations in our operating results, announcements of technological
innovations, new products or services introduced by us or our competitors,
changes in financial estimates by securities analysts, conditions and trends in
the software market, general market conditions and other factors. Historically,
the trading volume of the common stock has been very small and the market for
the common stock has been materially less liquid than that of most other
publicly traded companies. Significant sales of common stock could have an
adverse effect on the market price of the common stock. Further, the stock
markets, and in particular the Nasdaq Stock Market, have experienced extreme
price and volume fluctuations that have particularly affected the market prices
of equity securities of many technology companies and that often have been
unrelated or disproportionate to the operating performance of such companies.
The trading prices of many technology companies' stocks are at or near
historical highs and reflect price to earnings ratios substantially above
historical levels. We cannot provide any assurance that these trading prices and
price to earnings ratios will be sustained. These broad market factors may
adversely affect the market price of our common stock. These market
fluctuations, as well as general economic, political and market conditions such
as recessions, interest rates or international currency fluctuations, may
adversely affect the market price of the common stock.

YEAR 2000 ISSUES COULD AFFECT OUR BUSINESS.

        We recognize the need to ensure that our operations will not be
adversely impacted by Year 2000 software failures. Software failures due to
processing errors potentially arising from calculations using the Year 2000 date
are a known risk. We have established procedures for evaluating and managing the

this problem, and, as part of the general upgrade of our information systems, we
are putting in place systems which will be Year 2000 compliant.

        IMSI has initiated a Year 2000 Compliance Plan that addresses three
types of systems that must be Year 2000 compliant.

        PRODUCTS: IMSI's software products have been undergoing Year 2000
Compliance testing since January 1998. Approximately 85% of our currently
supported products have been verified as Year 2000 Compliant; the remaining
products are expected to be verified as compliant by June 1999.

        IT SYSTEMS: We have identified all internal data processing and
networking systems that we believe are at risk from the Year 2000 problem and we
are currently reviewing the manufacturer's Year 2000 Compliance statement for
each system. Any systems that are determined to be non-compliant will be
upgraded or replaced. Internal testing will be initiated for any missing
critical system for which the manufacturer's Year 2000 Compliance statement is
not adequate to ensure the reliability of the system. All IT systems will be
verified as Year 2000 Compliant by July 1999. In addition, no new IT systems
will be implemented without first ensuring that they are Year 2000 Compliant.

        NON-IT-SYSTEMS: We have identified a wide range of general computing and
facilities systems that must be verified as Year 2000 Compliant. The majority of
these systems will be upgraded or replaced as necessary during normal
maintenance if they are not compliant. The manufacturer's Year 2000 Compliance
statements are currently under review for the remaining systems and will be
upgraded or replaced if necessary. Because new systems are continually being
integrated into IMSI, the effort to ensure Year 2000 Compliance for these
systems is an ongoing effort.

        We have communicated with others with whom we do significant business to
determine their Year 2000 compliance readiness and the extent to which IMSI is
vulnerable to any third party Year 2000 issues. However, there can be no
guarantee that the systems of other companies on which our systems rely will be
timely converted, or that a failure to convert by another company, or a
conversion that is incompatible with our systems, would not have a material
adverse effect on IMSI, results of operations and our financial condition.

                                 USE OF PROCEEDS

        Except in the event that warrants are exercised for cash (in which case
we would receive proceeds from the exercise) rather than being net exercised,
for the exercise of warrants we will not receive any proceeds from the sale of
the common stock by the selling stockholders.

                its former shareholders, amending the Exchange Agreement and
                Zedcor Fee Agreement, among other agreements.

        Zedcor Agreements. In October 1998, IMSI acquired all the outstanding
common stock of Zedcor, Inc. ("Zedcor"), an Internet provider of art and
animations, pursuant to the Exchange Agreement. The total purchase price
consisted of cash, a promissory note for $2,229,500, and 176,455 shares of
common stock. Pursuant to the terms of the Exchange Agreement, we are
registering the shares of common stock that the Zedcor stockholders listed below
received in this transaction. On February 25, 1999, IMSI entered into a fee
agreement with Zedcor. Under the terms of the Zedcor Fee Agreement, IMSI issued
190,797 shares of common stock (as amended in May 1999) and in satisfaction of a
debt owed Zedcor under the terms of the Exchange Agreement described above. The
shares were priced at $8.00 and on the closing date the closing price of the
common stock was $11.438. In May 1999, IMSI entered into an agreement with
Zedcor and its former shareholders pursuant to which IMSI agreed, among other
things, to issue approximately 10,000 shares of common stock in consideration of
the release of a security interest in favor of the former Zedcor shareholders
and certain other agreements by those shareholders. IMSI agreed to register the
above shares for resale.


        The Warrant Agreement. On November 3, 1998, we borrowed funds under a
three-year subordinated loan facility with Silicon Valley Bank. As part of the
loan facility, IMSI issued warrants, which have a five-year term, to purchase
30,000 shares of common stock with an exercise price of $7.00 per share. As part
of the original loan agreement dated November 3, 1998, IMSI was required to
register shares by February 1, 1999. On January 26, 1999, Silicon Valley Bank
and IMSI agreed to extend this deadline until May 5, 1999. Additional warrants
are required to be granted as follows:

</TABLE>

IMSI is registering 30,000 of the shares issuable upon exercise of these
warrants, under the terms of IMSI's agreements with the bank. If it is necessary
to register the remaining shares, IMSI will do so at a later date.



                                       14

        Asset Purchase Agreement. On December 24, 1998, IMSI purchased certain
assets of clipartconnection.com, an Internet provider of art and animation, for
a purchase price of 18,053 shares of common stock. The share price used for
calculation and the closing price on the Closing were commensurate. IMSI agreed
to register those shares for resale.

        Garay Fee Agreement. On January 11, 1999, IMSI entered into a fee
agreement with the Law Offices of Mark Garay, Inc. ("Garay") Under the terms of
the Garay Fee Agreement, IMSI issued 11,112 shares of our common stock in
satisfaction of a debt owed to Garay. The shares were priced at $9.00 and on the
closing date the closing price of the common stock was IMSI common stock was
trading at $10.25. IMSI agreed to register those shares for resale.

        TLC Fee Agreement. On October 2, 1998, The Learning Company, Inc.
("TLC") and IMSI entered into a software license agreement whereby TLC sold Org
Plus to us in exchange for current and future cash payments. In January 1999,
IMSI and TLC agreed to amend the terms of the Org Plus agreement to allow IMSI
to settle the portion of the purchase price not paid at the closing by the
issuance of 200,000 shares of common stock. The shares were priced at $9.00, and
on the closing date the closing price of the common stock was $12.00. IMSI
agreed to register those shares for resale. In addition, IMSI has agreed that if
TLC sells any shares pursuant to this prospectus within 30 days of the effective
date of the registration statement to which this registration statement relates,
at a sale price of less than the price per share of the common stock as of April
30, 1999, IMSI will pay TLC the difference between the price TLC receives per
share and the price per share as of April 30, 1999 in cash, or IMSI may make up
the shortfall by issuing additional shares equal to the difference in the
selling price multiplied by the weighted average of the shares during the thirty
day protection period.

        Green Tree Fee Agreement. On February 18, 1999, IMSI entered into a fee
agreement with Green Tree Technologies, Inc. ("Green Tree")to satisfy a debt we
owed Green Tree under the terms of a software license agreement between IMSI and
Green Tree. In settlement of this debt, we issued to Green Tree 18,053 shares.
The shares were priced at $8.31 and on the closing date the closing price of the
common stock was $11.00. IMSI agreed to register those shares for resale.


        Capital Ventures International Agreement. On March 3, 1999, IMSI entered
into a stock purchase agreement and related agreements with Capital Ventures
International ("CVI"). Under the terms of the agreement, CVI paid us $5,000,000
and we issued 437,637 shares of our common stock. We may be required to issue
additional shares depending on the occurrence of certain events, including the
market price of the common stock on certain future dates. In particular, if the
average of the closing prices of our common stock for the five trading days
before the date that the registration statement of which this prospectus is a
part is declared effective by the SEC is less than $11.42, then we are obligated
to issue additional shares to CVI so that CVI's per share purchase price equals
that average market price, but in all events no lower than approximately $7.99.
This floor price can be reduced if we complete a "Financing Transaction," as
defined in the agreements with CVI, at certain prices within certain periods of
time after the closing of the CVI transaction. The shares were priced at $11.42
and on the closing date the closing price of the common stock was $11.563.
Additionally, pursuant to the CVI agreement, CVI can purchase up to $3,000,000
worth of additional shares of common stock, up to a maximum of 375,117 shares.
CVI also acquired a warrant to purchase 131,291 shares of common stock. IMSI
agreed to register the shares issued or issuable pursuant to these agreements.
Under the agreements with CVI, if the registration statement is not declared
effective before July 3, 1999, then we are obligated to pay to CVI certain
amounts, which could be material depending on several factors including the
length of time before this registrations statement is declared effective.

         Following the closing of the BayStar Financing, CVI notified IMSI that
CVI believes that as a result of the BayStar Financing, the floor price under
the CVI agreements relating to possible issuance of additional shares to CVI
depending on the average market price of our common stock on the date this
registration statement is declared effective should be reduced from $7.99 to a
significantly lower number, possibly approximately $4.25. IMSI disagrees with
CVI's assertions concerning the extent of any reduction to this share limit
price. To our knowledge, CVI has not yet filed any lawsuits against us, but CVI
may in the future file an action against us asserting the above claims and
possibly other claims, seeking damages and other relief including issuance of
additional shares of common stock to CVI, depending on the market price of our
common stock when this registration statement is declared effective. If CVI were
ultimately to prevail in any such action, we might be required to pay damages
and/or issue additional shares of common stock to CVI. We currently believe that
the maximum number of additional shares we would be required to issue if CVI
were to prevail would be approximately 738,834 shares, but we cannot provide any
assurances concerning the outcome of any such action, if brought. This
prospectus includes an additional 700,000 shares of common stock which may,
depending on various circumstances described above, become issuable to CVI.

        HomeStyles Agreement. On January 11, 1999, IMSI entered into a fee
agreement with HomeStyles, Inc. ("HomeStyles") to satisfy a $90,000 debt we owed
HomeStyles under the terms of various software license agreement between IMSI
and HomeStyles. In settlement of this debt, we issued to HomeStyles 10,000
shares of common stock. The shares were priced at $9.00 and on the closing date
the closing price of the common stock was $10.25. IMSI agreed to register those
shares for resale.

        Minnevich Agreement. On January 11, 1999, IMSI entered into a fee
agreement with Joseph Minnevich ("Minnevich") to satisfy a $45,000 debt we owed
Minnevich under the terms of various software license agreement between IMSI and
Minnevich. In settlement of this debt, we issued to Minnevich 5,000 shares of
common stock. The shares were priced at $9.00 and on the closing date the
closing price of the common stock was $10.25. IMSI agreed to register those
shares for resale.

        Gateway Agreement. On March 1, 1999, IMSI entered into a fee agreement
with Gateway Acceptance Co. ("Gateway") to satisfy a $72,000 debt we owed
Gateway under the terms of various manufacturing agreements between IMSI and
Gateway. In settlement of this debt, we issued to Gateway 8,000 shares of common
stock. The shares were priced at $9.00 and on the closing date the closing price
of the common stock was $11.438. IMSI agreed to register those shares for
resale.

        Spatial Agreement. On March 25, 1999, IMSI entered into a fee agreement
with Spatial Technology, Inc. ("Spatial") to satisfy a $45,000 debt we owed
Spatial under the terms of various software license agreements between IMSI and
Spatial. In settlement of this debt, we issued to Spatial 5,000 shares of common
stock. The shares were priced at $9.00 and on the closing date the closing price
of the common stock was $11.25. IMSI agreed to register those shares for resale.

        StarBase Agreement. On March 26, 1999, IMSI entered into a fee agreement
with StarBase Corporation ("StarBase") to satisfy a debt we owed StarBase under
the terms of various software license agreements between IMSI and StarBase. In
settlement of this debt, we issued to StarBase 10,750 shares of common stock.
The share price used for calculation and the closing price on the closing were
commensurate. IMSI agreed to register those shares for resale.

        The following table sets forth information with respect to the selling
stockholders and the shares of the common stock that may be offered pursuant to
this prospectus (the "shares"). Except as provided below, none of the selling
stockholders has, or within the past three years has had, any position, office
or other material relationship with us or any of our predecessors or affiliates.

        The selling stockholders may from time to time offer and sell any or all
of their shares pursuant to this prospectus. Because the selling stockholders
are not obligated to sell shares of common stock, and because selling
stockholders may also acquire publicly traded shares of our common stock, we
cannot estimate how many shares of common stock each selling stockholder will
beneficially own after this offering

                              PLAN OF DISTRIBUTION

        We have filed a Registration Statement of which this prospectus forms a
part pursuant to registration rights we granted to the selling stockholders
pursuant to (1) the Exchange Agreement; (2) the Warrant Agreement; (3) the Asset
Purchase Agreement; (4) the Garay Fee Agreement; (5) the TLC Fee Agreement; (6)
the Greentree Fee Agreement; (7) the Zedcor Fee Agreement; and (8) the Capital
Ventures International agreements.

<PAGE>   18

        To IMSI's knowledge, no selling stockholder has entered into any
agreement, arrangement or understanding with any particular broker or market
maker with respect to the shares of common stock offered hereby, nor does IMSI
know the identity of the brokers or market makers that will participate in the
sale of the shares. As used in this prospectus, the term "selling stockholders"
includes donees and pledgees selling shares received from a named selling
stockholder after the date of this prospectus.

        Who May Sell; How Much; Applicable Restrictions. The selling
stockholders may from time to time offer the shares of common stock through
brokers, dealers or agents who may receive compensation in the form of
discounts, concessions or commissions from the selling stockholders and/or the
purchasers of the shares of common stock for whom they may act as agent. In
effecting sales, broker-dealers that are engaged by the selling stockholders may
arrange for other broker-dealers to participate. The selling stockholders and
any such brokers, dealers or agents who participate in the distribution of the
shares of common stock may be deemed to be "underwriters," and any profits on
the sale of the shares of common stock by them and any discounts, commissions or
concessions received by any such brokers, dealers or agents might be deemed to
be underwriting discounts and commissions under the Securities Act. To the
extent the selling stockholders may be deemed to be underwriters, the selling
stockholders may be subject to certain statutory liabilities of, including but
not limited to, Sections 11, 12 and 17 of the Securities Act and Rule 10b-5
under the Exchange Act. To our knowledge, there are currently no plans,
arrangements or understandings between any selling stockholders and any broker,
dealer, agent or underwriter regarding the sale of the shares of common stock by
the selling stockholders.

        Manner of Sales and Applicable Restrictions. The selling stockholders
will act independently of IMSI in making decisions with respect to the timing,
manner and size of each sale. Such sales may be made over the Nasdaq Stock
Market or otherwise, at then prevailing market prices, at prices related to
prevailing market prices or at negotiated prices. The shares of common stock may
be sold according to one or more of the following methods:

        (a)     a block trade in which the broker or dealer so engaged will
                attempt to sell the shares of common stock as agent but may
                position and resell a portion of the block as principal to
                facilitate the transaction;

        (b)     purchases by a broker or dealer as principal and resale by such
                broker or dealer for its account pursuant to this prospectus;

        (c)     an over-the-counter distribution in accordance with the Nasdaq
                rules;

        (d)     ordinary brokerage transactions and transactions in which the
                broker solicits purchasers;

        (e)     privately negotiated transactions.

        Certain persons participating in this offering may engage in
transactions that stabilize, maintain or otherwise affect the price of our
common stock, including the entry of stabilizing bids or syndicate covering
transactions or the imposition of penalty bids. The selling stockholders and any
other person participating in such distribution will be subject to applicable
provisions of the Exchange Act and the rules and regulations thereunder
including, without limitation, Regulation M (which regulation may limit the
timing of purchases and sales of any of the shares of common stock by the
selling stockholders and any other such person). The anti-manipulation rules
under the Exchange Act may apply to sales of shares of common stock in the
market and to the activities of the selling stockholders and their affiliates.
Furthermore, Regulation M of the Exchange Act may restrict the ability of any
person engaged in the distribution of the shares of common stock to engage in
market-making activities with respect to the particular shares of common stock
being distributed for a period of up to five business days prior to the
commencement of such distribution. All of the foregoing may affect the
marketability of the shares of common stock and the ability of any person or
entity to engage in market-making activities with respect to the shares of
common stock. Under the terms of its asset purchase agreement,
clipartconnection.com agreed to limit to ten percent of the total number of
shares, the number of shares it holds that are covered by this prospectus it
will sell in any one month period during the twelve months following the date
its shares become tradable unless we consent otherwise. Clipartconnection.com
also agreed to give us ten business days advance notice of any proposed sale of
common stock. IMSI has a perpetual right of first refusal to either purchase
such shares or to arrange for a third party to purchase the shares.



                                       17
<PAGE>   19

        Rules 101 and 102 of Regulation M under the Exchange Act, among other
things, generally prohibit certain participants in a distribution from bidding
for or purchasing for an account in which the participant has a beneficial
interest, any of the securities that are the subject of the distribution. Rule
104 of Regulation M governs bids and purchases made to stabilize the price of a
security in connection with a distribution of the security.

        Hedging and Other Certain Transactions with Broker-Dealers. In
connection with distributions of the shares of common stock or otherwise, the
selling stockholders may enter into hedging transactions with broker-dealers. In
connection with such transactions, broker-dealers may engage in short sales of
the shares of common stock registered hereunder in the course of hedging the
positions they assume with selling stockholders. The selling stockholders may
also sell shares of common stock short and redeliver the shares of common stock
to close out such short positions. The selling stockholders may also enter into
option or other transactions with broker-dealers which require the delivery to
the broker-dealer of the shares of common stock registered hereunder, which the
broker-dealer may resell or otherwise transfer pursuant to this prospectus.
Selling stockholders may also loan or pledge the shares of common stock
registered hereunder to a broker-dealer and the broker-dealer may sell the
shares of common stock so loaned or, upon a default, the broker-dealer may
effect sales of the pledged shares of common stock pursuant to this prospectus.

        Expenses Associated With Registration. We have agreed to pay the
expenses of registering the shares of common stock under the Securities Act,
including registration and filing fees, printing expenses, administrative
expenses and certain legal and accounting fees. Each of the selling stockholders
will bear its pro rata share of all discounts, commissions or other amounts
payable to underwriters, dealers or agents as well as fees and disbursements for
legal counsel retained by any such selling stockholder.

        Indemnification. Under the terms of the Garay Fee Agreement, the TLC Fee
Agreement, the Capital Ventures International Agreement, the Greentree Fee
Agreement, and the Zedcor Fee Agreement, we have agreed to indemnify each of the
parties to the agreements and certain other persons against certain liabilities
in connection with the offering of the shares of common stock, including
liabilities arising under the Securities Act.

        Prospectus Updates; Suspension of this Offering. At any time a
particular offer of the shares of common stock is made, a revised prospectus or
prospectus supplement, if required, will be distributed. Such prospectus
supplement or post-effective amendment will be filed with the SEC to reflect the
disclosure of required additional information with respect to the distribution
of the shares of common stock. Under the terms of the Garay Fee Agreement, the
TLC Fee Agreement, the Greentree Fee Agreement, and the Zedcor Fee Agreement,
upon the occurrence of any event known to our executive officers as a result of
which this prospectus is known by our executive officers to include an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing, the parties have each agreed not to
trade shares of common stock from the time the selling stockholder receives
notice from IMSI of such an event until such party receives a prospectus
supplement or amendment. Upon the occurrence of such an event, a prospectus
supplement or post-effective amendment, if required, will be distributed to the
parties.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Section 317 of the California Corporations Code provides that a corporation
shall have the power to indemnify any person who was or is a party or is
threatened to be made a party to any proceeding (other than an action by or in
the right of the corporation to procure a judgment in its favor) by reason of
the fact that the person is or was an agent of the corporation, against
expenses, judgments, fines, settlements, and other amounts actually and
reasonably incurred in connection with the proceeding if that person acted in
good faith and in a manner the person reasonably believed to be in the best
interests of the corporation and, in the case of a criminal proceeding, had no
reasonable cause to believe the conduct of the person was unlawful. The
termination of any proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which the
person reasonably believed to be in the best interests of the corporation or
that the person had reasonable cause to believe that the person's conduct was
unlawful.

Section 5 of Article II of IMSI's By-laws, provides as follows:

        Section 5. INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS.

        (a) Authorization. The corporation may indemnify any director, officer,
        agent or employee as to those liabilities and on those terms and
        conditions as are specified in Section 317 of the General Corporation
        Law. In any event, the corporation shall have the right to purchase and
        maintain insurance on behalf of any such persons whether or not the
        corporation would have the power to indemnify such person again the
        liability insured against.

        (b) Indemnification. To the fullest extent permissible under Section 317
        of the General Corporation Law, the corporation shall indemnify its
        directors and officers against all expenses, judgments, fines,
        settlements and other amounts actually and reasonably incurred by them
        in connection with any proceeding, including an action by or in the
        right of the corporation, by reason of the fact that such person is or
        was a director, officer employee or other agent of the corporation, or
        is or was serving at the request of the corporation as a director,
        officer, trustee, employee or agent of another corporation, at the
        request of the corporation as a director, officer, trustee, employee or
        agent of another corporation, or of a partnership, joining venture,
        trust or other enterprise (including service with respect to employee
        benefit plans), or was a director, officer, employee or agent of a
        foreign or domestic corporation which was a predecessor corporation of
        the corporation or of another enterprise at the request of the
        predecessor corporation. To the fullest extent permissible under Section
        317 of the General Corporation Law, expenses incurred by a director or
        officer seeking indemnification under this By-law in defending any
        proceeding shall be advanced by the corporation as they are incurred
        upon receipt by the corporation of an undertaking by or on behalf of the
        director or officer to repay such amount if it shall ultimately be
        determined that the director or officer is not entitled to be
        indemnified by the corporation for those expenses. The rights granted by
        this By-law are contractual in nature and, as such, may not be altered
        with respects to any present or former director or officer without the
        written consent of that person.

        (c) Procedure. Upon written request to the Board of Directors by a
        person seeking indemnification under this By-law, the Board shall
        promptly determine in accordance with



                                       20
<PAGE>   23

        Section 317(e) of the General Corporation Law whether the applicable
        standard of conduct has been met and, if so, the Board shall authorize
        indemnification. If the Board cannot authorize indemnification because
        the number of directors who are parties to the proceeding with respect
        to which indemnification is sought prevents the formation of a quorum of
        directors who are not parties to the proceeding, then, upon written
        request by the person seeking indemnification, independent legal counsel
        (by means of a written opinion obtained at the corporation's expense) or
        the corporation's stockholders shall determine whether the applicable
        standard of conduct has been met and, if so, shall authorize
        indemnification.

        (d) Definitions. The term "proceeding" means any threatened, pending or
        completed action or proceeding, whether civil, criminal, administrative
        or investigative. The term "expenses" includes, without limitation,
        attorneys' fees and any expenses of establishing a right to
        indemnification.

ITEM 17.  UNDERTAKINGS.



                                       22
<PAGE>   24

Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of the Registrant
pursuant to the provisions described under Item 15 above, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement: (i) to include any
prospectus required by Section 10(a)(3) of the Securities Act of 1933 (the
"Securities Act"); (ii) to reflect in the prospectus any facts or events arising
after the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information in the Registration Statement;
and (iii) to include any material information with respect to the plan of
distribution not previously disclosed in the Registration Statement or any
material change to such information in the Registration Statement; provided,
however, that (i) and (ii) do not apply if the information required to be
included in a post-effective amendment thereby is contained in periodic reports
filed by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 (the "Exchange Act") that are incorporated by
reference in the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act,
each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

(3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

(4) That, for purposes of determining any liability under the Securities Act,
each filing of the Registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act that is incorporated by reference in this
Registration Statement shall be deemed to be a new Registration Statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         Time on March 5, 1999 or such other date as the parties may mutually
         agree ("TRANCHE 1 CLOSING DATE"). The Tranche 1 Closing shall occur at
         the offices of Gibson, Dunn & Crutcher LLP, One Montgomery Street,

         Capital Transaction and during the period from such announcement
         through and including the date on which the Capital



                                       4
<PAGE>   5

         Transaction is consummated but in all events no later than the Tranche
         2 Trigger Date (the "CAPITAL TRANSACTION PERIOD"), the Purchaser shall
         have the right, but not the obligation, to buy, and the Company shall
         have the obligation to sell to the Purchaser, on the Tranche 2 Closing
         Date (as hereafter defined), a maximum number of whole shares of Common
         Stock as is equal to the quotient of (I) Three Million Dollars
         ($3,000,000) divided by (II) an amount (the "TRANCHE 2 PER SHARE

         September 6, 1999, but not less than $7.9975. For avoidance of doubt,
         clause (y) of the preceding sentence shall be applicable only in
         connection with Optional Tranche 2 Shares issued on or after September
         6, 1999. The shares of Common Stock acquired on the Tranche 2 Closing

         (the "TRANCHE 2 PURCHASE PRICE") equal to the product of (i) the number
         of Optional Tranche 2 Shares to be acquired on the Tranche 2 Closing
         Date in accordance with the terms of this Section 1(d) and (ii) the
         Tranche 2 Per Share Price which amount shall constitute the total
         purchase price for the Optional Tranche 2 Shares. The Purchaser shall
         notify the Company in writing (the "TRANCHE 2 PURCHASE NOTICE") no
         later than 11:00 a.m. San Francisco Time on the third Business Day
         preceding the Tranche 2 Trigger Date, or, during the Capital
         Transaction Period, at any time beginning on the commencement of the
         Capital Transaction Period and ending on the third Business Day
         preceding the proposed consummation of the Capital Transaction, but in
         all events no later than the third Business Day preceding the Tranche 2
         Trigger Date, whether the Purchaser desires to purchase the Optional
         Tranche 2 Shares, setting forth the number of shares the Purchaser
         desires to purchase; provided, however, that the Tranche 2 Purchase
         Notice may condition the Purchaser's election to close such purchase
         upon the consummation of the Capital Transaction.

                  ii. The Tranche 2 Per Share Price or the Optional Tranche 2
         Shares shall be subject to adjustment from time to time as follows:

                           (A) If the Company at any time after the Tranche 1
                  Closing Date, but before the Tranche 2 Closing Date,
                  subdivides (by any stock split, stock dividend,
                  recapitalization, reorganization, reclassification or
                  otherwise) its shares of Common Stock into a greater number of
                  shares, then, after the date of record for effecting such
                  subdivision, the Tranche 2 Per Share Price in effect
                  immediately prior to such subdivision will be proportionately
                  reduced. If the Company at any time after the Tranche 1
                  Closing combines (by reverse stock split, recapitalization,
                  reorganization, reclassification or otherwise) its shares of
                  Common Stock into a smaller number of shares, then, after the
                  date of record for effecting such combination, the Tranche 2
                  Per Share Price in effect immediately prior to such
                  combination will be proportionately increased.

                           (B) In case, after the Tranche 1 Closing Date but
                  before the Tranche 2 Closing Date of any consolidation of the
                  Company with, or merger of the Company into any other entity
                  in which the Company is not the surviving entity, or in case
                  of any sale or conveyance of all or substantially all of the
                  assets of the



                                       5
<PAGE>   6

                  Company other than in connection with a plan of complete
                  liquidation of the Company at any time after the Tranche 1
                  Closing, then as a condition of such consolidation, merger or
                  sale or conveyance, adequate provision will be made whereby
                  the Purchaser will have the right, at its sole option, to
                  acquire and receive in lieu of the Optional Tranche 2 Shares
                  such shares of stock, securities or assets as may be issued or
                  payable with respect to or in exchange for the Optional
                  Tranche 2 Shares acquirable hereunder had such Optional
                  Tranche 2 Shares been issued immediately prior to the
                  consummation of such consolidation, merger or sale or
                  conveyance. In any such case, the Company will make
                  appropriate provision to insure that the provisions of this
                  Section 1.d.ii (B) hereof will thereafter be applicable as
                  nearly as may be in relation to any shares of stock or
                  securities thereafter deliverable in lieu of the Optional
                  Tranche 2 Shares. The Company will not effect any
                  consolidation, merger or sale or conveyance unless prior to
                  the consummation thereof, the successor corporation (if other
                  than the Company) assumes by written instrument the
                  obligations under this Section 1.d.ii and the obligations to
                  deliver to the Purchaser such shares of stock, securities or
                  assets as, in accordance with the foregoing provisions, the
                  Purchaser may be entitled to acquire.

                           (C) In case after the Tranche 1 Closing Date, but
                  before the Tranche 2 Closing Date, the Company shall declare
                  or make any distribution of its assets (or rights to acquire
                  its assets) to holders of Common Stock as a partial
                  liquidating dividend, by way of return of capital or otherwise
                  (including any dividend or distribution to the Company's
                  shareholders of cash or shares (or rights to acquire shares)
                  of capital stock of a subsidiary) (a "DISTRIBUTION") at any
                  time after the Tranche 1 Closing, then, in each case, the
                  Tranche 2 Purchase Price shall be reduced as of the seventh
                  business day after the record date with respect to such
                  distribution so that the same shall be equal to the price
                  determined by multiplying the Tranche 2 Purchase Price in
                  effect immediately prior to the close of business on such
                  record date by a fraction the numerator of which is the
                  average Closing Price for the five trading days immediately
                  after such record date, and the denominator shall be the
                  average Closing Price for the five trading days immediately
                  prior to such record date, such reduction to become effective
                  immediately prior to the opening of business on the day
                  following the record date.

                  iii. On the Tranche 2 Closing Date, the Purchaser shall pay
         the Tranche 2 Purchase Price by wire transfer to the Company, in
         accordance with the Company's written wiring instructions against
         delivery of certificates representing the Optional Tranche 2 Shares
         against delivery of the Tranche 2 Purchase Price.

                  iv. Subject to the satisfaction (or waiver) of the conditions
         thereto set forth in Section 5 and Section 6 below, the date and time
         of the sale of the Optional Tranche 2 Shares pursuant to this Agreement
         (the "TRANCHE 2 CLOSING") shall be 5:00 p.m. San Francisco Time on the
         fifth Business Day following the date of the Tranche 2 Purchase Notice
         or such later date if mutually agreed by the parties hereto (the
         "TRANCHE 2 CLOSING



                                       6
<PAGE>   7

         DATE"). The Tranche 2 Closing shall occur at the offices of Gibson,
         Dunn & Crutcher LLP, One Montgomery Street, Telesis Tower, San
         Francisco, California 94104 or at such other place as the parties may
         otherwise agree.

                  v. If the Company fails for any reason to issue the Optional
         Tranche 2 Shares on the Tranche 2 Closing Date, then in addition to all
         other rights and remedies that the Purchaser may have under this
         Agreement or at law or equity, the Company shall pay to the Purchaser
         as liquidated damages ("TRANCHE 2 LIQUIDATED DAMAGES") an amount equal
         to (I) Thirty Thousand Dollars ($30,000) for the first month following
         the Tranche 2 Closing Date and (II) Sixty Thousand Dollars ($60,000)
         for each month thereafter that the Company fails to issue the Optional
         Tranche 2 Shares. In addition, the Purchaser shall have the option to
         demand at any time beginning five Business Days after the Tranche 2
         Closing Date, that the Company pay to it an amount (the "OPTIONAL
         TRANCHE 2 DAMAGES") in cash equal to (x) the difference between the
         Tranche 2 Per Share Price and the Closing Price on the Tranche 2
         Closing Date, multiplied by (y) the number of Optional Tranche 2 Shares
         the Company was to have delivered to the Purchaser on the Tranche 2
         Closing Date. If the Company fails to pay the Purchaser the Optional
         Tranche 2 Damages within one Business Day (the "OPTIONAL DAMAGES
         PAYMENT DATE") of the date the Purchaser makes such demand, then the
         Company shall pay to the Purchaser an amount equal to (A) one percent
         (1%) of the amount of the Optional Tranche 2 Damages for the first
         month following the Optional Damages Payment Date and (B) two percent
         (2%) of the amount of the Optional Tranche 2 Damages for each month
         thereafter that the Company fails to pay the Optional Tranche 2
         Damages.

         e. Adjustment Shares; Share Limit. If the Market Price on the
Adjustment Date is lower than the Tranche 1 Per Share Price paid by the
Purchaser on the Tranche 1 Closing Date, then, within three Business Days of the
Adjustment Date, the Company shall cause to be issued to the Purchaser a number
of additional whole shares of Common Stock (the "ADJUSTMENT SHARES") equal to
(I) the quotient of (x) Five Million Dollars ($5,000,000) divided by (y) an
amount equal to the Market Price on the Adjustment Date; minus (II) the number
of Tranche 1 Shares purchased by the Purchaser on the Tranche 1 Closing Date;
provided, however, that the Company shall not be required to issue to the
Purchaser a number of shares which, when aggregated with the Tranche 1 Shares,
would exceed the Share Limit. The Adjustment Shares shall deemed to be
outstanding as of the Adjustment Date.

2.       PURCHASER'S REPRESENTATIONS AND WARRANTIES.

         The Purchaser represents and warrants to the Company as follows:

         a. Purchase for Own Account. The Purchaser is purchasing the Securities
for the Purchaser's own account and not with a present view towards the
distribution thereof. Notwithstanding anything in this Section 2(a) to the
contrary, by making the foregoing representation, the Purchaser does not agree
to hold the Securities for any minimum or other specific term and reserves the
right to dispose of the Securities at any time in accordance with or



                                       7
<PAGE>   8

pursuant to a registration statement or an exemption from registration under the
Securities Act and any applicable state securities laws.

         b. Information. The Purchaser has been furnished all materials relating
to the business, finances and operations of the Company and materials relating
to the offer and sale of the Securities which have been requested by the
Purchaser. The Purchaser has been afforded the opportunity to ask questions of

         c. Governmental Review. The Purchaser understands that no United States
federal or state agency or any other government or governmental agency has
passed upon or made any recommendation or endorsement of the Securities.

and delivered on behalf of the Purchaser and is a valid and binding agreement of
the Purchaser enforceable in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
other laws affecting creditors' rights and remedies generally and to general
principles of equity (regardless of whether enforcement is sought in a

         statement for the securities under applicable securities laws unless
         offered, sold or transferred under an available exemption from the
         registration requirements of those laws.

         The legend set forth above shall be removed and the Company shall issue
a certificate without such legend to the holder of any Security upon which it is
stamped, if, unless otherwise required by state securities laws, (a) the sale of
such Security is registered under the Securities Act (including registration
pursuant to Rule 416 thereunder), or (b) such holder provides the Company with
an opinion of counsel reasonably acceptable to the Company, in form, substance
and scope customary for opinions of counsel in comparable transactions, to the
effect that a public sale or transfer of such Security may be made without
registration under the Securities Act or (c) such holder provides the Company
with reasonable assurances that such Security can be sold under Rule 144(k). The
Purchaser agrees to sell all Securities, including those represented by a
certificate(s) from which the legend has been removed, pursuant to an effective
registration statement or under an exemption from the registration requirements
of the Securities Act. Such legend shall be removed when such Security may be
sold pursuant to an effective registration statement or sold under Rule 144(k).

will not (i) conflict with or result in a violation of the Articles of
Incorporation or By-laws or (ii) conflict with, or constitute a default (or an
event which with notice or lapse of time or both would become a default) under,
or give to others any rights of termination, amendment, acceleration or
cancellation of any agreement, indenture or instrument to which the Company or
any of its subsidiaries is a party, or result in a violation of any law, rule,
regulation, order, judgment or decree (including United States federal and state
securities laws and regulations) applicable to the Company or any of its

amendment, acceleration or cancellation of, any agreement, indenture or
instrument to which the Company or any of its subsidiaries is a party, except
for actual or possible violations, defaults or rights as would not, individually

Company and its subsidiaries are not being conducted in violation of any law,
ordinance or regulation of any governmental entity, except for actual or
possible violations, if any, the sanctions for which either singly or in the
aggregate would not have a Material Adverse Effect. Except as specifically
contemplated by this Agreement and as required under the Securities Act and any
applicable state securities laws, the Company is not required to obtain any
consent, approval, authorization or order of, or make any filing or registration
with, any court or governmental agency or any regulatory or self regulatory

under this Agreement (including, without limitation the issuance and sale of the
Shares and Warrant as provided hereby), or the Warrants (including the issuance
of the Warrant Shares), in each case in accordance with the terms hereof or
thereof. The Company is not in violation of the listing requirements of the
Nasdaq National Market ("NASDAQ") and does not reasonably anticipate that the
Common Stock will be delisted by NASDAQ in the foreseeable future.

         f. SEC Documents Financial Statements. Since January 1, 1996, the
Company has filed all reports, schedules, forms, statements and other documents

and documents incorporated by reference therein, being hereinafter referred to
herein as the "SEC DOCUMENTS"). The Company has made available to the Purchaser
true and complete copies of the SEC Documents, except for the exhibits and
schedules thereto and the documents incorporated therein. As of their respective
dates, the SEC Documents complied in all material respects with the requirements
of the Exchange Act or the Securities Act, as the case may be, and the rules and
regulations of the SEC promulgated thereunder applicable to the SEC Documents,
and none of the SEC Documents, at the time they were filed with the SEC,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Any statements made in any such SEC Documents that are or were
required to be updated or amended under applicable law has been or have been so
updated or amended. As of their respective dates, the financial statements of
the Company included in the SEC Documents complied in all material respects with
applicable accounting requirements and the published rules and regulations of
the SEC applicable with respect thereto. Such financial statements have been
prepared in accordance with United States generally accepted accounting
principles, consistently applied, during the periods involved (except (i) as may
be otherwise indicated in such financial statements or the notes thereto, or
(ii) in the case of unaudited interim statements, to the extent they may not
include footnotes or may be condensed or summary statements) and fairly present
in all material respects the consolidated financial position of the Company and
its consolidated subsidiaries as of the dates thereof and the consolidated
results of their operations and cash flows for the periods then ended (subject,
in the case of unaudited statements, to normal and recurring year-end audit
adjustments). Except as set forth in the SEC Documents filed prior to the date
hereof, the Company has no liabilities, contingent or otherwise, other than (i)
liabilities incurred in the ordinary course of business subsequent to the date
of such SEC Documents and (ii) obligations under contracts and commitments
incurred in the ordinary course of business and not required under generally
accepted accounting principles to be reflected in such SEC Documents, which
liabilities and obligations referred to in clauses (i) and (ii), individually or
in the aggregate would not have a Material Adverse Effect.

         g. Absence of Certain Changes. Except as disclosed in the SEC
Documents, since December 31, 1998, there has been no change or development
which individually or in the aggregate has had or would have a Material Adverse
Effect.

         h. Absence of Litigation. Except as disclosed in the SEC Documents,
there is no action, suit, proceeding, inquiry or investigation before or by any
court, public board, government agency, self-regulatory organization or body
pending or threatened against or affecting the Company, any of its subsidiaries,
or any of their respective directors or officers in their capacities as such
which would have a Material Adverse Effect or which would adversely affect the
validity, enforceability of, or the authority or ability of the Company to
perform its obligations under this Agreement (including the issuance of the
Shares and the Warrants), the



                                       12
<PAGE>   13

Registration Rights Agreement, the Warrants (including the issuance of the
Warrant Shares) or any other agreement or document delivered pursuant hereto or
thereto.

         i. Intellectual Property. Each of the Company and its subsidiaries owns
or is licensed to use all patents, patent applications, trademarks, trademark
applications, trade names, service marks, copyrights, copyright applications,
licenses, permits, know-how (including trade secrets and other unpatented and/or
unpatentable proprietary or confidential information, systems or procedures) and
other similar rights and proprietary knowledge (collectively, "INTANGIBLES")
necessary for the conduct of its business as now being conducted. Neither the
Company nor any subsidiary of the Company infringes or is in conflict with any
other person with respect to any Intangibles which, individually or in the
aggregate, if the subject of an unfavorable decision, ruling or finding, would
have a Material Adverse Effect. Neither the Company nor any of its subsidiaries
has received written notice that it is infringing upon third party Intangibles.
Neither the Company nor any of its subsidiaries has entered into any consent,
indemnification, forbearance to sue or settlement agreements with respect to the
validity of the Company's or its subsidiaries' ownership or right to use its
Intangibles and there is no reasonable basis for any such claim to be
successful. The Intangibles are valid and enforceable and no registration
relating thereto has lapsed, expired or been abandoned or canceled or is the
subject of cancellation or other adversarial proceedings, and all applications
therefor are pending and in good standing. The Company and its subsidiaries have
complied, in all material respects, with their respective contractual
obligations relating to the protection of the Intangibles used pursuant to
licenses. To the Company's knowledge, person is infringing on or violating the
Intangibles owned or used by the Company or its subsidiaries.

         j. Foreign Corrupt Practices. Neither the Company, nor any of its
subsidiaries, nor any director, officer, agent, employee or other person acting
on behalf of the Company or any subsidiary has, in the course of his actions
for, or on behalf of, the Company, used any corporate funds for any unlawful
contribution, gift, entertainment or other unlawful expenses relating to
political activity; made any direct or indirect unlawful payment to any foreign
or domestic government official or employee from corporate funds; violated or is
in violation of any provision of the United States Foreign Corrupt Practices Act
of 1977; or made any bribe, rebate, payoff, influence payment, kickback or other
unlawful payment to any foreign or domestic government official or employee.

         k. Environment. Except as disclosed in the SEC Documents (i) there is
no material environmental liability, nor factors likely to give rise to any
environmental liability, affecting any of the material properties of the Company
or any of its subsidiaries that, individually or in the aggregate, would have a
Material Adverse Effect and (ii) neither the Company nor any of its subsidiaries
has violated or infringed any environmental law now in effect nor has any such
entity violated or infringed any then current environmental law as applied at
that time, other than such violations or infringements that, individually or in
the aggregate, have not had and will not have a Material Adverse Effect.

         l. Title. The Company and its subsidiaries have good title in fee
simple to all real property and good title to all personal property owned by
them which is material to the business



                                       13
<PAGE>   14

of the Company and its subsidiaries, in each case free and clear of all liens,
encumbrances and defects except for such defects in title that, individually or
in the aggregate, could not reasonably be expected to have a Material Adverse
Effect. Any real property and facilities held under lease by the Company and its
subsidiaries are held by them under valid, subsisting and enforceable leases
with such exceptions which have not had and will not have a Material Adverse
Effect.

         m. Insurance. Each of the Company and each of its subsidiaries has its
assets insured against loss or damage as is appropriate to its business and
assets, in such amounts and against such risks as are customarily carried and
insured against by owners of comparable businesses and assets, and such
insurance coverages will be continued in full force and effect to and including
each Closing Date other than those insurance coverages in respect of which the
failure to continue in full force and effect could not reasonably be expected to
have a Material Adverse Effect.

         n. Disclosure. All information relating to or concerning the Company
set forth in this Agreement or provided to the Purchaser pursuant to Section
2(b) hereof and otherwise in connection with the transactions contemplated
hereby is true and correct in all material respects and the Company has not
omitted to state any material fact necessary in order to make the statements
made herein or therein, in light of the circumstances under which they were
made, not misleading. No event or circumstance has occurred or exists with
respect to the Company or its subsidiaries or their respective businesses,
properties, operations, prospects or financial conditions, which has not been
publicly disclosed but, under applicable law, rule or regulation, would be
required to be disclosed by the Company in a registration statement filed on the
date hereof by the Company under the Securities Act with respect to a primary
issuance of the Company's securities. The Company has not provided, and without
the Purchaser's consent thereto, will not hereafter provide to the Purchaser,
any information which, according to applicable law, rule or regulation, should
have been disclosed publicly by the Company but which has not been disclosed.

         o. Acknowledgment Regarding the Purchaser's Purchase of the Securities.
The Company acknowledges and agrees that the Purchaser is not acting as a
financial advisor or fiduciary of the Company (or in any similar capacity) with
respect to this Agreement or the transactions contemplated hereby, and the
relationship between the Company and the Purchaser is "arms length" and that any

person to which or to whom brokerage commissions, finder's fees, financial
advisory fees or similar payments are or will become due in connection with this
Agreement or the transactions contemplated hereby.

               the claim and, when known, the facts constituting the basis for
               such claim. In the event of any such claim for indemnification
               hereunder resulting from or in connection with any claim or legal
               proceedings by a third party. The Indemnified Party shall not
               settle or compromise any claim by a third party for which it is

               consent of the Indemnifying Party, which shall not be
               unreasonable withheld, unless suit shall have been instituted
               against it and the Indemnifying Party shall not have taken
               control of such suit after notification thereof as provided in
               Section 4.1 of this Agreement.

         4.3   Payment of Indemnification Obligation. The Seller hereby agrees
               that any claim for indemnification by the IMSI under this Section
               4 or under any other provision of this Agreement may, at IMSI's
               option, be set off against any of the IMSI's obligations to make
               payments to the Seller under this Agreement, if any.

  5.     CONFIDENTIALITY

         5.1   All documentation and information provided to in anticipation
               of this agreement, both written and oral, by the party
               disclosing the information ("the Disclosing Party") is
               proprietary or confidential, including without limitation the
               terms of this or any other agreement between the parties,
               financial documents, copies of third party agreements in whole
               or in part, drawings, computer program listings, techniques,
               algorithms and processes and technical and marketing
               information ("Confidential Information.") All information
               supplied by the Disclosing Party in connection with this
               Agreement shall be treated confidentially by the recipient of
               the confidential information ("Recipient") and its employees,
               and shall


3
<PAGE>   4



               not be disclosed by the Recipient without the Disclosing Party's
               prior written consent.

        5.2    The parties agree that, in the event of Recipient's breach or
               threatened breach of the confidentiality provision hereof, an
               action at law for damages would not be adequate to protect the
               rights of the Disclosing Party. Therefore, Recipient agrees that
               in the event of a breach or threatened breach, the disclosing
               party shall be entitled to injunctive and/or other equitable
               relief to prevent a breach thereof and to secure their
               enforcement, which shall be in addition to any other rights of
               the disclosing party. Recipient acknowledges and agrees that the
               Disclosing party shall be entitled to punitive damages in the
               event that the confidentiality provision is breached.

minus (i) the Transaction Shares multiplied by the IMSI Average Price per Share,
minus (ii) $300,000. Such balance shall be paid pursuant to the terms of the

                        2.1.1 Exchange of Zedcor Stock. At the Closing, each
share of Zedcor Stock that is issued and outstanding immediately prior to the
Closing will be exchanged for a number of shares of IMSI Common Stock equal to
the Exchange Number, subject to the provisions of Section 2.1.2 regarding the
elimination of fractional shares. Subject to surrender and delivery to IMSI by
each Zedcor Shareholder of the applicable Zedcor Certificates at the Closing and
an accompanying Stock Power (in a form approved by counsel to IMSI and IMSI's
transfer agent) and Form W-8, each Zedcor Shareholder shall receive a stock
certificate for its Exchange Shares within twenty (20) business days after the
Closing Date.

                        2.1.2 Fractional Shares. No fractional shares of IMSI
Common Stock shall be issued in connection with the Exchange.

                        2.1.3 Registration Rights. Effective upon the Closing,
each Zedcor Shareholder who receives shares of IMSI Common Stock in the Exchange
shall be granted registration rights under the Securities Act of 1933, as
amended (the "1933 ACT".) IMSI shall endeavor to register the Zedcor shares of
IMSI Common Stock in the Exchange the next time IMSI does a stock registration
filing with the SEC on a form suitable for registration of such shares (i.e.,
not a form relating to employee benefit plans, a merger or similar transaction.)
Nothing herein shall require IMSI to separately register the Zedcor shares of
IMSI Common Stock in the Exchange.

                        2.1.4 Limitations on Sale, Transfer of IMSI Common
Stock. Zedcor and the Zedcor shareholders respectively, shall not sell,
transfer, gift or encumber in excess of thirty three and one third percent
(33.3%) of the total number of shares of IMSI Common Stock provided to such
Zedcor shareholder pursuant to this Agreement, in any one calendar month during
the three (3) month period following the date the IMSI Common Stock becomes
tradable without the prior written consent of IMSI. Additionally, the Zedcor
shareholders shall give IMSI advance written notice of any proposed sale of IMSI
Common Stock pursuant to this Agreement, at least five (5) business days in
advance of the proposed sale. IMSI shall have a perpetual right of first refusal
to either purchase such proposed sale shares or to arrange for a third party to
purchase such shares.

                2.2 Settlement Account. Zedcor shall have until October 31,
1998, to negotiate Zedcor long term and short term debts and Zedcor shall have
limited access to cash on the balance sheet after the Agreement Date to effect
such negotiations. Except for cash in Zedcor's operating account immediately
prior to the Agreement, Zedcor shall not dispose of, transfer title or otherwise
encumber the Zedcor assets without the prior written approval of IMSI. On or
before October 31, 1998, Zedcor shall use best efforts to deliver to IMSI a zero
balance sheet including all accruals for



                                       4
<PAGE>   5

all expenses (including taxes) incurred up to and including October 31, 1998,
prepared in accordance with generally accepted accounting principals and subject
to final review and approval by IMSI. However IMSI shall accept residual long or
short term debt in an amount not to exceed fifty thousand dollars ($50,000.00.)
Residual long or short term debt in an amount not to exceed fifty thousand
dollars ($50,000.00) will not constitute a material breach of this Agreement.
Any residual long or short term debt in excess of fifty thousand dollars
($50,000.00) shall be deducted from the initial payment. IMSI shall be entitled
to make payments on such residual long or short term debt according to IMSI's
internal accounting procedures, and Zedcor shall not bind IMSI to any payment
schedule without the prior written consent of IMSI.

                2.3 Adjustments for Capital Changes. Notwithstanding the
provisions of Section 2.1, if at any time after the Agreement Date and prior to
the Closing, IMSI or Zedcor recapitalizes, either through a subdivision (or
stock split) of any of its outstanding shares into a greater number of shares,
or a combination (or reverse stock split) of any of its outstanding shares into
a lesser number of shares, or reorganizes, reclassifies or otherwise changes its
outstanding shares into the same or a different number of shares of other
classes (other than through a subdivision or combination of shares provided for
in the previous clause), or declares a dividend on its outstanding shares
payable in shares or securities convertible into shares of IMSI Common Stock (a
"CAPITAL CHANGE"), then the number of shares of IMSI Common Stock for which
shares of Zedcor Stock are to be exchanged in the Exchange, shall be
appropriately, equitably and proportionately adjusted (as agreed to by IMSI and
Zedcor if the adjustment for such Capital Change involves something other than a
mathematical adjustment) so as to maintain the proportionate interests of the
shareholders of Zedcor and the shareholders of IMSI contemplated hereby so as to
maintain the proportional interests of the holders of Zedcor Stock and
contemplated by this Agreement. The provisions of this Section shall not apply
to any transaction not permitted to be undertaken by Zedcor under the provisions
of this Agreement. In the event that a Capital Change affecting IMSI Common
Stock occurs prior to the Closing, then all prices per share and numbers of
shares used to compute the Exchange Number shall be deemed to have been
equitably adjusted to reflect such Capital Change as necessary to effect the
purposes and intent of this Section.

                2.4 Hold Back. After the Closing and prior to or in conjunction
with any accelerated payment by IMSI of the Purchase Price Balance, IMSI may, in
its sole discretion, withhold four hundred thousand dollars ($400,000.00) of the
Purchase Price Balance to be paid to the Zedcor Shareholders in accordance with
Section 2, (the "HOLD BACK FUNDS") as security for the Zedcor Shareholders'
indemnification obligations under Section 11. The Hold Back Funds will be held
by IMSI for thirty months after the Closing Date. Upon the thirtieth month after
the Closing Date, IMSI shall release one hundred thousand dollars ($100,000.00)
of the Hold Back Funds assuming any monies are remaining, to the Zedcor
shareholders. Upon the thirty sixth month following the Closing Date, IMSI shall
release to the Zedcor Shareholders the remaining Hold Back Funds. The Zedcor
Shareholders hereby consent to, approve and agree to be personally bound by the
indemnification provisions of Section 11 of this Agreement and the appointment
of Michael Gariepy as the representative of the Zedcor Shareholders and as the
attorney-in-fact and agent for and on behalf of each Zedcor Shareholder, and the
taking by the Representative of any and all actions and the making of any and
all decisions required or permitted to be taken by the Representative under this
Agreement (including, without limitation, the exercise by the Representative of

the Set Off claims by IMSI or any other Indemnified Person (as defined herein);

and enter into settlements and compromises of such claims, and demand
arbitration and comply with orders of courts and awards of arbitrators with
respect to such claims; (iii) arbitrate, resolve, settle or compromise any claim
for indemnity made pursuant to Section 11; and (iv) take all actions necessary
in the judgment of the Representative for the accomplishment of the foregoing).
The Representative will have unlimited authority and power to act on behalf of
each Zedcor Shareholder with respect to the Hold Back Funds and the disposition,
settlement or other handling of all claims governed by this Agreement, and all
rights or obligations arising under this Agreement so long as all Zedcor
Shareholders are treated in the same manner. The Zedcor Shareholders will be
bound by all actions taken by the Representative, and IMSI will be entitled to
rely on any action or decision of the Representative. In performing the
functions specified in this Agreement, the Representative will not be liable to
the Zedcor Shareholders in the absence of gross negligence or willful misconduct
on the part of the Representative. Any out-of-pocket costs and expenses
reasonably incurred by the Representative in connection with actions taken
pursuant to this Agreement will be paid by the Zedcor Shareholders to the
Representative in proportion to their respective percentage interest.

                2.5 Further Assurances. If, at any time after the Closing, IMSI
considers or is advised that any further instruments, deeds, assignments or
assurances are reasonably necessary or desirable to consummate the Exchange or
to carry out the purposes of this Agreement at or after the Closing, then IMSI,
Zedcor and their respective officers and directors may, and each Zedcor
Shareholder shall, execute and deliver all such proper deeds, assignments,
instruments and assurances and do all other things necessary or desirable to
consummate the Exchange and to carry out the purposes and intent of this
Agreement, in the name of Zedcor or otherwise.

and the IMSI Options pursuant to an exemption from registration under Section
4(2) and/or Regulation D promulgated under the 1933 Act. Concurrently with
execution of this Agreement, each Zedcor Shareholder will execute and deliver to
IMSI an Investment Representation Letter in the form of EXHIBIT 2.6-A hereto
(the "INVESTMENT REPRESENTATION LETTER").

condition (financial or otherwise), properties, assets, liabilities, business,

Limited Liability Company, joint venture or other business entity. EXHIBIT 3.4

limited liability company, joint venture or other business entity held by Zedcor
(the "ZEDCOR SUBSIDIARIES".)

                3.5 No Violation of Existing Agreements. Neither the execution
and delivery of this Agreement or any Zedcor Ancillary Agreement, nor the
consummation of the Exchange or any of the other transactions contemplated
hereby, nor Zedcor's discussion or negotiation with IMSI of the Exchange or any
other transaction contemplated hereby, will conflict with, or (with or without
notice or lapse of time, or both) result in a termination, breach, impairment or
violation of: (i) any provision of the charter documents of Zedcor as currently
in effect; (ii) any federal, state, local or foreign judgment, writ, decree,
order, statute, rule or regulation applicable to Zedcor or its assets or
properties; or (iii) any material instrument, agreement, contract, letter of
intent or commitment to which Zedcor is a party or by which Zedcor or its assets
or properties are or were bound. The consummation of the Exchange by Zedcor will
not require the consent of any third party other than the approval of the Zedcor
Shareholders and no agreement to which Zedcor is a party requires that any other
party thereto consent to the Exchange, whether as a condition to the assignment
or transfer of such agreement, or otherwise.

                3.6 Litigation. There is no action, suit, arbitration,
mediation, proceeding, claim or investigation pending against Zedcor (or against
any officer or director of Zedcor or, to the best of the knowledge of Zedcor and
the Zedcor Shareholders, against any employee or agent of Zedcor, in their
capacity as such or relating to their employment, services or relationship with
Zedcor) before any court, administrative agency or arbitrator that, if
determined adversely to Zedcor (or any



                                       8
<PAGE>   9

such officer, director, employee or agent) may reasonably be expected to have a
Material Adverse Effect on Zedcor, nor, to the best of Zedcor's knowledge, has
any such action, suit, proceeding, arbitration, mediation, claim or
investigation been threatened. There is no basis for any person, firm,
corporation or other entity, to assert a claim against Zedcor or IMSI based
upon: (a) Zedcor's entering into this Agreement or consummating the Exchange;
(b) any claims of ownership, rights to ownership, or options, warrants or other
rights to acquire ownership, of any shares of the capital stock of Zedcor; or
(c) any rights as a Zedcor shareholder, including any option, warrant or
preemptive rights or rights to notice or to vote. There is no judgment, decree,

threatened, claimed, proposed or assessed. Zedcor has not received any
notification that any issues have been raised (and are currently pending) by any

audited consolidated statements of cash flows and audited consolidated statement
of shareholders' equity for the six-month period ended August 1998 (all such
financial statements of Zedcor are hereinafter collectively referred to as the
"ZEDCOR FINANCIAL STATEMENTS"). The Zedcor Financial Statements



                                       9
<PAGE>   10

shall (a) be in accordance with the books and records of Zedcor, (b) fairly
present the financial condition of Zedcor at the dates therein indicated and the
results of operations for the periods therein specified and (c) have been
prepared in accordance with generally accepted accounting principles applied on
a consistent basis with prior periods. Zedcor has no material debt, liability or
obligation of any nature (whether intercompany or owed to third parties),
whether accrued, absolute, contingent or otherwise, and whether due or to become
due, except for (i) those shown on the unaudited August 1998 balance sheet
included in the Unaudited Zedcor Financials (the "UNAUDITED BALANCE SHEET"), and
(ii) those that may have been incurred after August 31, 1998 (the "BALANCE SHEET
DATE") in the ordinary course of Zedcor's business consistent with past
practice, and that are not material in amount, either individually or
collectively. All reserves established by Zedcor and set forth in the Unaudited
Balance Sheet are reasonably adequate. At the Balance Sheet Date, there were no
material loss contingencies (as such term is used in United States Statement of
Financial Accounting Standards No. 5 issued by the Financial Accounting
Standards Board in March 1975) which are not adequately provided for in the
Balance Sheet as required by said Statement No. 5.

                3.9 Title to Properties. Zedcor has good and marketable title to
all of its assets (including but not limited to those shown on the Balance
Sheet), free and clear of all liens, mortgages, security interests, claims,
charges, restrictions or encumbrances. All machinery, vehicles, equipment and
other tangible personal property included in such assets and properties are in
good condition and repair, normal wear and tear excepted, and all leases of real
or personal property to which Zedcor is a party are fully effective and afford
Zedcor peaceful and undisturbed possession of the real or personal property that
is the subject of the lease. Zedcor is not in violation of any zoning, building,
safety or environmental ordinance, regulation or requirement or other law or
regulation applicable to the operation of owned or leased properties (the
violation of which would have a Material Adverse Effect on its business), nor
has Zedcor received any notice of violation with which it has not complied.
Zedcor does not own any real property.

                3.10 Absence of Certain Changes. Since the Balance Sheet Date,
there has not been with respect to Zedcor any:

                        (a) material adverse change in the condition (financial
or otherwise), properties, assets, liabilities, businesses, operations, results
of operations or prospects of Zedcor;

                        (b) amendments or changes in the charter documents of
Zedcor;

                        (c) (i) incurrence, creation or assumption by Zedcor of
any mortgage, security interest, pledge, lien or other encumbrance on any of the
assets or properties of Zedcor or any material obligation or liability or any
indebtedness for borrowed money; or (ii) issuance or sale of, or change with
respect to the rights of, any debt or equity securities of Zedcor or any options

ordinary course of business after the Balance Sheet Date;

disposition, of any of the assets, properties or goodwill of Zedcor other than
in the ordinary course of its business consistent with its past practice;

                        (f) damage, destruction or loss, whether or not covered
by insurance, having (or likely with the passage of time to have) a Material
Adverse Effect on Zedcor;

                        (g) declaration, setting aside or payment of any

arrangement (including without limitation stock awards, stock appreciation
rights or stock option grants) made to or with any of such officers, employees,
consultants or agents except in connection with normal salary or performance
reviews or otherwise in the ordinary course of business consistent with Zedcor's
past practice;

                        (i) change with respect to the management, supervisory
or other key personnel of Zedcor;

                        (j) obligation or liability incurred by Zedcor to any of

or obligation or such other party's desire to so amend, relinquish, terminate or
not renew any such contract, lease, transaction, commitment or other right or
obligation;

                        (m) material change in the manner in which Zedcor

                        (o) transfer or grant of a right under any Zedcor IP
Rights (as defined in Section 3.13 below), other than those transferred or

                        (p) agreement or arrangement made by Zedcor to take any

                A copy of each agreement or document required by this Section to
be listed on Exhibit 3.11 (collectively, the "ZEDCOR MATERIAL AGREEMENTS") has
been delivered to IMSI. No consent or approval of any third party is required to
ensure that, following the Closing, any Zedcor Material Agreement shall continue
to be in full force and effect without any breach or violation thereof caused by
virtue of the Exchange or by any other transaction called for by this Agreement.

                3.12 No Default. Zedcor is not in breach or default of, and has
not breached or been in default of, any Zedcor Material Agreement. Zedcor is not
a party to any contract, agreement or arrangement, which has had, or could
reasonably be expected to have, a Material Adverse Effect on Zedcor. Zedcor does
not have any material liability for renegotiation of government contracts or
subcontracts, if any.

                3.13 Intellectual Property.

                        3.13.1 Zedcor owns, or has the irrevocable right to use,
sell or license all Intellectual Property Rights (as defined below) necessary or
required for the conduct of its business as presently conducted, including
without limitation the appropriate rights to each and every item of visual
content on its web site or in its inventory, and as presently proposed to be
conducted (such Intellectual Property Rights being hereinafter collectively
referred to as the "ZEDCOR IP RIGHTS"), and such rights to use, sell or license
are sufficient for such conduct of its business. Zedcor is the legal and
beneficial owner or licensee of all rights, including all copyright, trademarks
and worldwide distribution rights, to those certain computer software programs
and visual content, including all object code, source code, configurations,
routines and algorithms contained therein with annotations and related
documentation, known as ArtToday and all visual content, together with all
alterations, modifications and reconfigurations thereof in all forms of
expression, including but not limited to, the source code, object code,
flowcharts, block diagrams, manuals and all other documentation no matter how
stored, transmitted, read or utilized and all copyrights, trade secrets,
patents, inventions (whether patentable or not), proprietary rights and
intellectual property rights associated therewith (collectively the "SOFTWARE").
The term "Zedcor IP Rights" includes, without limitation, the Software and the
visual content. Zedcor, and each Zedcor Shareholder jointly and severally, shall
indemnify and hold harmless IMSI, its successors and assigns of IMSI, its board,
employees, shareholders, for any claim of unauthorized use of the visual content
of Zedcor, exploited by Zedcor, delivered to IMSI at the Closing or as
reasonably used or modified by IMSI in



                                       13
<PAGE>   14

good faith, where such use occurred during the three (3) year period following
the Closing Date. ZEDCOR IS SOLELY RESPONSIBLE TO VERIFY THE AUTHORIZED USE OF
ALL VISUAL CONTENT ON ITS WEB SITE OR IN ITS POSSESSION AT THE CLOSING DATE
WITHOUT LIMITATION. IMSI EXPRESSLY DISCLAIMS ANY AUDIT OR DUE DILIGENCE
RESPONSIBILITY RELATED TO THE ZEDCOR VISUAL CONTENT. Any and all rights to the
Software or visual content previously owned or held by third parties, including
(but not limited to) the Zedcor Subsidiaries (including those Zedcor
Subsidiaries named below), have been transferred to Zedcor and are owned
outright, free and clear of any claims, liens, security interest, mortgages,
encumbrances or obligations, by Zedcor.

                        3.13.2 The execution, delivery and performance of this
Agreement and the consummation of the Exchange and the other transactions
contemplated hereby will not constitute a material breach of or default under
any instrument, contract, license or other agreement governing any Zedcor IP
Right (the "ZEDCOR IP RIGHTS AGREEMENTS") and will not cause the forfeiture or
termination, or give rise to a right of forfeiture or termination, of any Zedcor
IP Right or materially impair the right of Zedcor or IMSI to use, sell, license,
provide or otherwise commercially exploit any Zedcor IP Right or portion thereof
(except where such breach, forfeiture or termination would not have a Material
Adverse Effect on Zedcor ). There are no royalties, honoraria, fees or other
payments payable by Zedcor to any person by reason of the ownership, use,
license, sale, exploitation or disposition of the Zedcor IP Rights.

                        3.13.3 Neither the manufacture, marketing, license,
sale, furnishing or intended use of any product, service or visual content
currently licensed, utilized, sold, provided, furnished, or possessed by Zedcor
or currently under development by Zedcor has violated or now violates any
license or agreement between Zedcor and any third party or infringes or
misappropriates any Intellectual Property Right of any other party; and there is
no pending or, to the best knowledge of Zedcor and the Zedcor Shareholders,
threatened claim or litigation contesting the validity, ownership or right to
use, sell, license or dispose of any Zedcor IP Right nor, to the best knowledge
of Zedcor and the Zedcor Shareholders, is there any basis for any such claim,
nor has Zedcor received any notice asserting that any Zedcor IP Right or the
proposed use, sale, license or disposition thereof conflicts or will conflict
with the rights of any other party, nor, to the best knowledge of Zedcor and the
Zedcor Shareholders, after through review by Zedcor's counsel, is there any
basis for any such assertion. To the best knowledge of Zedcor and the Zedcor
Shareholders, no employee or agent of or consultant to Zedcor is in violation of
any term of any employment contract, patent disclosure agreement, noncompetition
agreement, non-solicitation agreement or any other contract or agreement, or any
restrictive covenant relating to the right of any such employee, agent or
consultant to be employed thereby, or to use trade secrets or proprietary
information of others, and the employment of such employees or engagement of
such agents and consultants does not subject Zedcor to any liability.

                        3.13.4 Zedcor has used best efforts to review all its
visual content to verify compliance with intellectual property and other law,
and to protect, preserve and maintain the secrecy and confidentiality of all
material Zedcor IP Rights and all Zedcor's proprietary rights therein. All
officers, employees, agents and consultants of Zedcor having access to
proprietary information have executed and delivered to Zedcor an agreement
regarding the protection of such proprietary information and the assignment of
inventions to Zedcor in the form provided to counsel



                                       14
<PAGE>   15

for IMSI and copies of all such agreements, executed by all such persons, have
been delivered to IMSI's counsel.

                        3.13.5 EXHIBIT 3.13 contains a list of all Zedcor IP
Rights and all worldwide applications, registrations, filings and other formal
actions made or taken pursuant to federal, state and foreign laws by Zedcor to
secure, perfect or protect its interest in Zedcor IP Rights, including, without
limitation, all patents, patent applications, copyrights (whether or not
registered), copyright applications, trademarks, service marks and trade names
(whether or not registered) and trademark, service mark and trade name
applications. Exhibit 3.13 lists, with respect to each item of Zedcor IP Rights,
the entity (Zedcor or one of the Zedcor Subsidiaries) which owns or holds such
IP Rights.

                        3.13.6 As used herein, the term "INTELLECTUAL PROPERTY

rights, trademarks, trademark applications, trade dress rights, trade names,
service marks, service mark applications, copyrights, copyright applications,

screens, layouts, inventions, development tools and all documentation and media
constituting, describing or relating to the above, including, without
limitation, visual content, manuals, memoranda and records.

                3.14 Compliance with Laws. Zedcor has complied, and is now and
at the Closing Date will be in compliance, in all material respects, with all
applicable national, state, local or foreign laws, ordinances, regulations, and
rules, and all orders, writs, injunctions, awards, judgments, and decrees
applicable to Zedcor or to Zedcor's assets, properties, and business. Zedcor
holds all permits, licenses and approvals from, and has made all filings with,
third parties, including government agencies and authorities, that are necessary
in connection with Zedcor's present business, except those where failure to do
so would not have a Material Adverse Effect.

                3.15 Certain Transactions and Agreements. None of the officers,
directors or shareholders of Zedcor (nor any beneficiaries of any trust that is
a Zedcor Shareholder), nor any member of their immediate families, has any
direct or indirect ownership interest in any firm or corporation that competes
with, or does business with, or has any contractual arrangement with Zedcor.
None of said officers, directors, employees or shareholders or any member of
their immediate families, is directly or indirectly interested in any contract
or informal arrangement with Zedcor, except for normal compensation for services
as an officer, director or employee thereof that have been disclosed to IMSI to
such persons. None of said officers, directors, employees or shareholders or
family members has any interest in any property, real or personal, tangible or
intangible (including but not limited to any Zedcor IP Rights or any other
Intellectual Property Rights) that is used in or that pertains to the business
of Zedcor, except for the normal rights of a shareholder.

                3.16 Employees, ERISA and Other Compliance.

                        3.16.1 Zedcor is in compliance in all material respects

in each of the jurisdictions in which it conducts business. A list of all
employees, officers and consultants of Zedcor, their title, date of hire,
employer entity and current compensation is set forth on EXHIBIT 3.16.1, which

agreement with respect to any of its employees, (iii) is not subject to any
other contract, written or oral, with any trade or labor union, employees'

have a material adverse effect on such labor relations. Neither Zedcor nor any
Zedcor Shareholder has any knowledge that any key employee of Zedcor intends to
leave the employ of Zedcor.

                        3.16.3 Zedcor will not, at the Closing Date, have any
"employee benefit plan," as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"). Zedcor has no pension plan
that constitutes, or has since the enactment of ERISA constituted, a
"multiemployer plan" as defined in Section 3(37) of ERISA. No Zedcor pension
plans are subject to Title IV of ERISA. Zedcor does not have any employee
benefit plans that are subject to statutory regulation under the laws of the
British Virgin Islands, the United Kingdom, Canada or Australia.

                        3.16.4 Zedcor, prior to the Closing Date, shall fulfill
any and all employment, severance or other similar contract, arrangement or
policy, each "employee benefit plan" as defined in Section 3(3) of ERISA (if
any) and each plan or arrangement (written or oral) providing for insurance
coverage (including any self-insured arrangements), workers' benefits, vacation
benefits, severance benefits, disability benefits, death benefits,

insurance, compensation or benefits for employees, consultants or directors
which is entered into, maintained or contributed to by Zedcor and covers any
employee or former employee or consultant or former consultant of Zedcor. Such
contracts, plans and arrangements are hereinafter collectively referred to as
the "ZEDCOR BENEFIT ARRANGEMENTS." Each Zedcor Benefit Arrangement has been
maintained in compliance in all material respects with its terms and with the
requirements prescribed by any and all laws, statutes, orders, rules and
regulations that are applicable to such Zedcor Benefit Arrangement. IMSI shall
have no liability for any Zedcor Benefit Arrangement.

                        3.16.5 There has been no amendment to, written
interpretation or announcement (whether or not written) by Zedcor relating to,
or change in employee participation or coverage under, any Zedcor Benefit
Arrangement that would increase materially the expense of maintaining such
Zedcor Benefit Arrangement above the level of the expense incurred in respect
thereof for Zedcor's fiscal year ended 12/31/97.

                        3.16.6 The group health plans (as defined in Section
4980B(g) of the Code) that benefit employees of Zedcor are in compliance, in all
material respects, with the continuation

<PAGE>   17

coverage requirements of Section 4980B of the Code as such requirements affect
Zedcor and its employees. As of the Closing Date, there will be no material
outstanding, uncorrected violations under the Consolidation Omnibus Budget
Reconciliation Act of 1985, as amended ("COBRA"), with respect to any of the
Zedcor Benefit Arrangements, covered employees, or qualified beneficiaries that
could result in a Material Adverse Effect on Zedcor, or in a material adverse
effect on the business, operations or financial condition of IMSI as its
successor. Zedcor has provided, or shall have provided prior to the Closing, to
individuals entitled thereto, all required notices and coverage pursuant to
Section 4980B of COBRA, with respect to any "qualifying event" (as defined in
Section 4980B(f)(3) of the Code) occurring prior to and including the Closing
Date, and no material amount payable on account of Section 4980B of the Code has
been incurred with respect to any current or former employees of Zedcor (or
their beneficiaries).

                        3.16.7 No benefit payable or which may become payable by
Zedcor pursuant to any Zedcor Benefit Arrangement or as a result of or arising
under this Agreement shall constitute an "excess parachute payment" (as defined
in Section 280G(b)(1) of the Code) which is subject to the imposition of an
excise tax under Section 4999 of the Code or which would not be deductible by
reason of Section 280G of the Code. Zedcor is not a party to any (a) agreement
(other than as described in (b) below) with any executive officer or other key
employee thereof (i) the benefits of which are contingent, or the terms of which
are materially altered, upon the occurrence of a transaction involving Zedcor in
the nature of any of the transactions contemplated by this Agreement, (ii)
providing any term of employment or compensation guarantee, or (iii) providing
severance benefits or other benefits after the termination of employment of such
employee regardless of the reason for such termination of employment, or (b)
agreement or plan, including, without limitation, any stock option plan, stock
appreciation rights plan or stock purchase plan, any of the benefits of which
will be materially increased, or the vesting of benefits of which will be
materially accelerated, by the occurrence of the Exchange or any of the other
transactions contemplated by this Agreement or the value of any of the benefits
of which will be calculated on the basis of any of the transactions contemplated
by this Agreement.

Material Adverse Effect.

its properties and facilities, there has been no litigation brought or
threatened against Zedcor, or, to the best knowledge of Zedcor and the Zedcor

                        10.1.6 The Board of Directors for IMSI must approve this

                                       31
<PAGE>   32

        11. SURVIVAL OF REPRESENTATIONS, INDEMNIFICATION AND REMEDIES,
CONTINUING COVENANTS

                11.1 Survival of Representations. All representations,
warranties and covenants of Zedcor and the Zedcor Shareholders contained in this
Agreement will remain operative and in full force and effect, regardless of any
investigation made by or on behalf of IMSI, until the earlier of (i) the
termination of this Agreement or (ii) thirty six (36) months after the Closing
Date; provided, however, that those representations and warranties respecting
matters addressed by the first audited financial statements of the combined
corporation, together with a report thereon from IMSI's independent auditors,
shall not expire later than upon the date on which such financial statements are
first released to the public.

                11.2 Agreement to Indemnify. The Majority Zedcor Shareholders
agree to jointly and severally indemnify and hold harmless IMSI and its
officers, directors, agents, shareholders and employees, and each person, if
any, who controls or may control IMSI within the meaning of the 1933 Act or the
1934 Act (each hereinafter referred to individually as an "INDEMNIFIED PERSON"
and collectively as "INDEMNIFIED PERSONS") from and against any and all claims,
demands, suits, actions, causes of actions, losses, costs, damages, liabilities
and expenses including, without limitation, reasonable attorneys' fees, other
professionals' and experts' reasonable fees and court or arbitration costs
(hereinafter collectively referred to as "DAMAGES") promptly as incurred and
arising out of any inaccuracy, misrepresentation, breach of, or default in, any
of the representations, warranties or covenants given or made by Zedcor and/or
the Majority Zedcor Shareholders in this Agreement or in the Zedcor Disclosure
Letter or in any certificate delivered by or on behalf of Zedcor pursuant hereto
(if such inaccuracy, misrepresentation, breach or default existed at the Closing
Date). Neither party shall settle any such claim or suit for which the Majority
Zedcor Shareholders are obligated to indemnify IMSI under this section without
the prior written consent of the other, which consent shall not be unreasonably
withheld. Any claim of indemnity made by an Indemnified Person under this
Section 11.2 must be asserted in writing and delivered to the Representative.

                (a) With respect to any portion of a claim or suit under this
                Section 11 that requires IMSI to recall, remaster, or
                rereplicate any hard media IMSI software product that includes
                Zedcor visual content, Zedcor shall not be responsible for
                IMSI's actual cost of such recall, remastering, or
                rereplication. Nothing herein shall limit Zedcor's
                indemnification responsibility for Damages except as
                specifically stated above.

                (b) In no event shall Zedcor's indemnification liability exceed
                the Purchase Price Balance or Hold Back Funds, plus fifty
                percent (50%) of any amounts already paid by IMSI in
                satisfaction of the purchase price.



                                       32
<PAGE>   33

                (c) In the event that any particular piece of visual content
                that is alleged to violate the intellectual property rights of
                any third party, was properly licensed by both IMSI and Zedcor
                at the Closing, Zedcor shall not be responsible for
                indemnification under this section for said duplicative image.
                Nothing herein shall limit Zedcor's indemnification
                responsibility for Damages except as specifically stated above.

                11.3 Set Off. Notwithstanding anything herein to the contrary,
in seeking indemnification for Damages under Section 11.2, the Indemnified
Persons shall have the ability to set off (the "SET OFF") the Damages from the
Purchase Price Balance and/or the Hold Back Funds.

                11.4 Notice. Promptly after IMSI becomes aware of the existence
of any potential claim by an Indemnified Person for indemnity from the Zedcor
Shareholders under Section 11.2, IMSI will notify the Zedcor Representative of
such potential claim and will, to the extent that it can reasonably do so
without impairing its ability to adequately defend and respond to any such
claim, permit the Zedcor Representative to assist IMSI in the defense of such
claim and will cooperate with the Zedcor Representative in obtaining copies of
any records or other information which is relevant to the defense of such claim.
Failure of IMSI to give such notice shall not affect any rights or remedies of
an Indemnified Party hereunder with respect to indemnification for Damages
except to the extent the Zedcor Shareholders are materially prejudiced thereby.
Prior to the settlement of any claim for which IMSI seeks indemnity from a
Zedcor Shareholder, IMSI will provide the Zedcor Shareholders with the terms of
the proposed settlement and a reasonable opportunity to comment on such terms in
accordance with the Escrow Agreement. Nothing in this Section is intended to
preclude the Representative of the Zedcor Shareholders from reasonably
contesting a claim for indemnification hereunder.

                11.5 Title Indemnity. In addition to, and separate from, the
foregoing agreement to indemnify set forth in Section 11.2, each Zedcor
Shareholder agrees, jointly and severally, to defend and indemnify IMSI and each
other Indemnified Person from and against any and all claims, demands, suits,
actions, causes of actions, losses, costs, damages, liabilities and expenses
including, without limitation, reasonable attorneys' fees, other professionals'
and experts' reasonable fees and court or arbitration costs incurred and arising
out of any failure of such Zedcor Shareholder to have good, valid and marketable
title to any issued and outstanding shares of Zedcor Stock held (or asserted to
have been held) by such Zedcor Shareholder, free and clear of all liens, claims
and encumbrances, or to have the full right, capacity and authority to enter
into this Agreement and consummate the Exchange and any other transactions
contemplated by this Agreement, or any failure of Zedcor to have good, valid and
marketable title to all of the outstanding shares of each of the Zedcor
Subsidiaries and any failure of the Zedcor Shareholders collectively to own, of
record and beneficially, 100% of the outstanding shares of Zedcor. A Zedcor
shareholder's liability under the indemnification provided for in this Section
11.5 shall be in addition to any liability of such Zedcor shareholder under
Section 11.2 and shall not be subject to the limitations on such shareholder's
liability set forth in Section 11.3 and shall not be limited to the Hold Back
Funds.

        12. MISCELLANEOUS

                12.1 Governing Law. The internal laws of the State of
California, U.S.A. (irrespective of its choice of law principles) will govern
the validity of this Agreement, the



                                       33
<PAGE>   34

construction of its terms, and the interpretation and enforcement of the rights
and duties of the parties hereto.

                12.2 Assignment; Binding Upon Successors and Assigns. Neither
party hereto may assign any of its rights or obligations hereunder without the
prior written consent of the other party hereto, except that IMSI may assign its
respective rights and/or obligations to any wholly-owned subsidiary of IMSI or
the surviving company in any merger or acquisition. This Agreement will be
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

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

                12.4 Counterparts. This Agreement may be executed in any number
of counterparts, each of which will be an original as regards any party whose
signature appears thereon and all of which together will constitute one and the
same instrument. This Agreement will become binding when one or more
counterparts hereof, individually or taken together, will bear the signatures of
both parties reflected hereon as signatories.

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

                12.6 Amendment and Waivers. IMSI and the Zedcor Shareholders (or
their successors in interest) may amend any term or provision of this Agreement
prior to the Closing by the written consent of IMSI, Zedcor and the Majority
Zedcor Shareholders, and, after the Closing. The observance of any term,
condition or provision of this Agreement may be waived (either generally or in a
particular instance and either retroactively or prospectively) only by a writing
signed by the party to be bound thereby or for whose benefit such condition was
provided. The waiver by a party of any breach hereof or default in the
performance hereof will not be deemed to constitute a waiver of any other
default or any succeeding breach or default. In addition, at any time prior to
the Closing, each of the Zedcor Shareholders and each of Zedcor and IMSI (by
action taken by its respective Board of Directors) may, to the extent legally
allowed: (i) extend the time for the performance of any of the obligations or
other acts of the other; (ii) waive any inaccuracies in the representations and
warranties made to it contained herein or in any document delivered pursuant
hereto; and (iii) waive compliance with any of the agreements or conditions for
its benefit contained herein. No such waiver or extension shall be effective
unless signed in writing by the party against whom such waiver or extension is
asserted. The failure of any party to enforce any of the provisions hereof will
not be construed to be a waiver of the right of such party thereafter to enforce
such provisions or any other provisions.

will not be construed for or against either party. A reference to a Section or

Agreement which will be considered as a whole.

                12.11 No Joint Venture. Nothing contained in this Agreement will
be deemed or construed as creating a joint venture or partnership between any of
the parties hereto. No party is by virtue of this Agreement authorized as an
agent, employee or legal representative of any other party. No party will have
the power to control the activities and operations of any other party and their
status is, and at all times will continue to be, that of independent contractors
with respect to each other. No party will have any power or authority to bind or
commit any other. No party will hold itself out as having any authority or
relationship in contravention of this Section.

                12.12 Further Assurances. Each party agrees to cooperate fully
with the other parties and to execute such further instruments, documents and
agreements and to give such further written assurances as may be reasonably
requested by any other party to evidence and reflect the transactions described
herein and contemplated hereby and to carry into effect the intents and purposes
of this Agreement.

                12.13 Absence of Third Party Beneficiary Rights. No provisions
of this Agreement are intended, nor will be interpreted, to provide or create
any third party beneficiary rights or any other rights of any kind in any
client, customer, affiliate, shareholder, partner, employee, agent, consultant
or any party hereto or any other person or entity unless specifically provided
otherwise herein, and, except as so provided, all provisions hereof will be
personal solely between the parties to this Agreement.

                12.14 Public Announcement. Upon execution of this Agreement,
IMSI and Zedcor will issue a press release approved by such parties announcing
the Exchange. Thereafter, IMSI may issue such press releases, and make such
other disclosures regarding the Exchange, as it determines are required under
applicable securities laws or regulatory rules, but shall first, when
practicable, consult with Zedcor and provide Zedcor with an opportunity to
comment on any such press release. Prior to the publication of the press release
issued upon execution of this Agreement (unless this Agreement has been
terminated), no party hereto shall make any public announcement relating to this
Agreement or the transactions contemplated hereby and Zedcor shall use its best
efforts to prevent any trading in IMSI Common Stock by officers, directors,
shareholders, employees, agents and consultants of Zedcor and/or of any Zedcor
Subsidiaries.

                12.15 Confidentiality. Zedcor and IMSI each confirm that they
have entered into the Confidentiality Agreement and that they are each bound by,
and will abide by, the provisions of such Confidentiality Agreement (except that
IMSI will cease to be bound by the Confidentiality Agreement after the Exchange
becomes effective). If this Agreement is terminated, all copies of documents
containing confidential information of a disclosing party shall be returned by
the receiving party to the disclosing party or be destroyed, as provided in the
Confidentiality Agreement.

                12.16 Entire Agreement. This Agreement and the exhibits hereto
constitute the entire understanding and agreement of the parties hereto with
respect to the subject matter hereof and supersede all prior and contemporaneous
agreements or understandings, inducements or conditions, express or implied,
written or oral, between the parties with respect hereto other than the
Confidentiality Agreement. The express terms hereof control and supersede any
course of performance or usage of the trade inconsistent with any of the terms
hereof.

                                                                   EXHIBIT 4.4
                                  FEE AGREEMENT

        This FEE AGREEMENT (the "Agreement") dated as of January 21, 1999 by and
between The Learning Company, Inc., a Delaware corporation ("TLC"), and
International Microcomputer Software, Inc. a California corporation ("IMSI").

        WHEREAS, IMSI currently owes TLC an amount equal to $1,800,000 (the
"Fees") pursuant to a Software License Agreement, dated October 2, 1998, between
TLC and IMSI (the "License Agreement"); and

        WHEREAS, TLC and IMSI now desire to set forth certain terms and
provisions with respect to the payment by IMSI of the Fees:

        NOW, THEREFORE in consideration of the foregoing and for other good and
valuable consideration (the receipt and sufficiency of which are hereby
acknowledged), the parties hereto hereby agree as follows:

        1. Payment of the Fees. Notwithstanding anything to the contrary in the
License Agreement with respect to the form and timing of payment of the Fees,
the obligations to pay the Fees shall the satisfied in full by compliance by
IMSI with the terms and provisions of this Agreement, including without
limitation, Section 2.

        2. Issuance of the Shares. On the next business day after the date
hereof, IMSI will issue to TLC 200,000 shares of IMSI's Common Stock (the
"Common Stock"), no par value (collectively, the "Shares").

        3. Sale. The Shares may be sold by one or more of the following means of
distribution (subject to the provisions of this Agreement): (a) a block trade in
which the broker-dealer so engaged will attempt to sell Shares as agent, but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a broker-dealer as principal and resale by such
broker-dealer for its own account; (c) an over-the-counter distribution in
accordance with the rules of Nasdaq; (d) ordinary brokerage transactions and
transactions in which the broker solicits purchasers; and (e) in privately
negotiated transactions.

        4. Representations, Warranties and Covenants of IMSI. IMSI represents
and warrants to and covenants with TLC as follows:

                a. IMSI is eligible to issue a Registration Statement on Form
S-3 for the resale of the Shares by TLC in accordance with the terms of this
Agreement. In



                                      -1-
<PAGE>   2

addition, a registration statement on Form S-3 with respect to the
Shares, including any amendment or amendments thereto, will (i) be prepared by
IMSI in conformity with the requirements of the Securities Act of 1933, as
amended (the "Securities Act"), and the rules and regulations of the Securities
and Exchange Commission (the "Commission") thereunder (the "Regulations"), and
will (ii) be filed with the Commission under the Securities Act as soon as
possible but in any event no later than February 28, 1999. Such registration
statement, as so amended, including the prospectus, financial statements and
schedules, exhibits and all other documents filed as part thereof, as amended at
the Effective Date, is herein called the "Registration Statement," and the
prospectus, in the form first filed with the Commission pursuant to Rule 424 (b)
of the Regulations or in the form filed as part of the Registration Statement at
the Effective Date, if no Rule 424 (b) filing is required, is herein called the
"Prospectus." Any reference herein to the Registration Statement or the
Prospectus shall be deemed to refer to and include the documents incorporated by
reference therein pursuant to Item 12 of Form S-3 which were filed under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), on or before
the Effective Date or the date of the Prospectus, as the case may be, and any
reference herein to the terms "amend," "amendment" or "supplement" with respect
to the Registration Statement or the Prospectus shall be deemed to refer to and
include (x) the filing of any document under the Exchange Act after the
Effective Date or the date of the Prospectus, as the case may be, which is
incorporated therein by reference and (y) any Such document so filed.

                b. IMSI will use best efforts to have the Registration Statement
declared effective as soon thereafter as possible. However, in the event that
IMSI's direct actions result in the Registration Statement not being declared
effective by April 30, 1999, TLC shall have the option to terminate this
agreement and return the Shares to IMSI. In such event, the amounts payable to,
and all rights of, TLC under the License Agreement shall be reinstated and all
amounts due under the License Agreement shall become due to TLC.

                c. At the date the Registration Statement becomes effective
under the Securities Act (the "Effective Date") or the time of effectiveness of
any post-effective amendment to the Registration Statement, at the time the
Prospectus is first filed with the Commission pursuant to Rule 424 (b) of the
Regulations (if a Rule 424 (b) filing is required), at the time any supplement
to or amendment of the Prospectus is filed with the Commission and at the time
any document filed under the Exchange Act is filed, the Registration Statement
and the Prospectus and any amendments thereof and supplements thereto complied
or will comply in all material respects with the applicable provisions of the
Securities Act and the Regulations or the Exchange Act and the respective rules
and regulations thereunder and do not or will not contain an untrue statement of
a material fact and do not or will not omit to state any material fact required
to be stated therein or



                                      -2-
<PAGE>   3

necessary in order to make the statements therein (i) in the case of the
Registration Statement, not misleading and (ii) in the case of the Prospectus,
in the light of the circumstances under which they were made, not misleading.

                d. The Shares, when issued and delivered in accordance with this
Agreement, will be duly and validly issued and outstanding, fully paid and
non-assessable and will not have been issued in violation of or be subject to
any preemptive rights.

                e. If at any time when a prospectus relating to the Shares is
required to be delivered under the Securities Act any event shall occur as a
result of which the Prospectus as then amended or supplemented, in the judgment
of TLC or IMSI, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it shall be necessary at any time to amend or
supplement the Prospectus or Registration Statement to comply with the
Securities Act or the Regulations, or to file under the Exchange Act so as to
comply therewith any document incorporated by reference in the Registration
Statement or the Prospectus or in any amendment thereof or supplement thereto,
(i) IMSI will notify TLC promptly and prepare and file with the Commission an
appropriate amendment or supplement (in form and substance satisfactory to TLC)
which will correct such statement or omission or which will effect such
compliance and will use its best efforts to have any amendment to the
Registration Statement docked declared effective by the Commission as soon as
possible and (ii) TLC shall suspend trading in the Shares until (A) such
amendment or supplement to the Prospectus has been filed or (B) any amendment to
the Registration Statement has been declared effective by the Commission.

                f. IMSI will provide TLC with conformed copies of the
Registration Statement and copies of the Prospectus.

                g. IMSI will pay all fees and expenses with respect to the
preparation and filing of the Registration Statement and the registration of the
Shares.

        5. Conditions to TLC's Obligations. The obligations of TLC hereunder are
subject to the accuracy, when made on the date hereof, of the representations
and warranties of IMSI contained herein, to the performance by IMSI of its
obligations hereunder and to the receipt by TLC of an opinion of Geoffrey
Koblick, IMSI General Counsel, addressed to TLC, dated the Effective Date, and
in form and substance satisfactory to TLC, to the effect that:



                                      -3-
<PAGE>   4

                a. all of the outstanding shares of Common Stock are duly and
validly authorized and issued, are fully paid and nonassessable and were not
issued in violation of or subject to any preemptive rights;

                b. the issuance of the Shares has been duly authorized by
requisite corporate action and, when issued and delivered by IMSI in accordance
with this Agreement, the Shares will be validly issued, fully paid and
nonassessable and will not have been issued in violation of or subject to any
preemptive rights;

                c. the Registration Statement, at the Effective Date, and the
Prospectus, at its date, and any amendments thereof or supplements thereto, at
their respective dates (other than financial statements and schedules and other
financial and statistical data included or incorporated by reference therein, as
to which no opinion need be rendered), complied in all material respects to the
requirements of the Securities Act and the Regulations and such counsel has no
reason to believe that the Registration Statement, at the Effective Date,
contained an untrue statement of a material fact or omitted to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading or that the Prospectus, at its date, contained an untrue
statement of a material fact or omitted to state a material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading; and

                d. each of the documents filed under the Exchange Act and
incorporated by reference in the Registration Statement, the Prospectus or any
amendment thereof or supplement thereto (other than the financial statements and
schedules and other financial and statistical data included or incorporated by
reference therein, as to which no opinion need be rendered), at the time it was
filed with the Commission, complied in all material respects to the requirements
of the Exchange Act and such counsel has no reason to believe that any of such
documents, when such documents were so filed, contained an untrue statement of a
material fact or omitted to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were made
when such documents were so filed, not misleading.

        6. Indemnification.

                a. IMSI agrees to indemnify and hold harmless TLC and each
person (each, a "TLC Controlling Person"), if any, who controls TLC within the
meaning of Section 15 of the Securities Act or Section 20 (a) of the Exchange
Act, against any and all losses, liabilities, claims, damages and expenses
whatsoever as incurred (including but not limited to attorneys' fees and any and
all expenses whatsoever incurred in



                                      -4-
<PAGE>   5

investigating, preparing or defending against any litigation, commenced or
threatened, or any claim whatsoever, and any and all amounts paid in settlement
of any claim or litigation), joint or several, to which they or any of them may
become subject under the Securities Act, the Exchange Act or otherwise, insofar
as such losses, liabilities, claims, damages or expenses (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement, as
originally filed or any amendment thereof, or the Prospectus, or in any
supplement thereto or amendment thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading;
PROVIDED, HOWEVER, that IMSI shall not be liable to TLC or any TLC Controlling
Person for any such losses, liabilities, claims, damages or expenses which arise
out of or are based upon an untrue statement or alleged untrue statement or
omission or alleged omission contained or made in the Registration Statement or
the Prospectus or any amendment thereof or Supplement thereto in reliance upon
and in conformity with information furnished to IMSI by TLC. IMSI and TLC hereby
agree that the number of shares held by TLC, and the possible manner of
reselling the Shares, is the only information supplied to IMSI by TLC for use in
connection with the preparation of the Registration Statement and the
Prospectus. This Indemnity Agreement will be in addition to any liability which
IMSI may otherwise have, including under this Agreement.

                b. Promptly after receipt by any indemnified party under
subsection a. above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the party against whom
indemnification is to be sought in writing of the commencement thereof (but the
failure so to notify an indemnifying party shall not relieve it from any
liability which it may have under this Section 6). In case any such action is
brought against any indemnified party, and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof with counsel satisfactory to
such indemnified party. Notwithstanding the foregoing, the indemnified party or
parties shall have the right to employ its or their own counsel in any such
case, but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by the indemnifying party in connection with the
defense of such action, (ii) the indemnifying party shall not have employed
counsel to have charge of the defense of such action within a reasonable time
after notice of commencement of the action, or (iii) such indemnified party
parties shall have reasonably concluded that there may be defenses available to
it or them which are different from or additional to those available to the
indemnifying party (in which case the indemnifying



                                      -5-
<PAGE>   6

party shall not have the right to direct the defense of such action on behalf of
the indemnified party or parties), in any of which events such fees and expenses
shall be borne by the indemnifying party. Anything in this subsection to the
contrary notwithstanding, the indemnifying party shall not be liable for any
settlement of any claim or action effected without its written consent:
PROVIDED, HOWEVER, that such consent was not unreasonably withheld.

        7. Entire Agreement. This Agreement and the License Agreement (to the
extent not inconsistent herewith) constitute the entire agreement between the
parties hereto with respect to the subject matter hereof and supersede all prior
written agreements and negotiations and oral understandings, if any, with
respect thereto. This Agreement may not be amended or supplemented except by an
instrument in writing signed by each of the parties hereto.

        8. Notices. All notices, requests and other communications hereunder

                                  FEE AGREEMENT

        This FEE AGREEMENT (the "Agreement") dated as of 18th February 1999 by
and between International Microcomputer Software, Inc. a California corporation
("IMSI"), and Greentree Technologies, Inc. a New York corporation ("Greentree").

        WHEREAS, IMSI currently owes Greentree an amount equal to $75,000.00
(the "Fees") pursuant to the Software License Agreement, dated December 2, 1997,
between IMSI and Greentree (the "Licensing Agreement"), and

        WHEREAS, IMSI and Greentree now desire to set forth certain terms and
provisions with respect to the payment by IMSI of the Fees:

        NOW, THEREFORE in consideration of the foregoing and for other good and
valuable consideration (the receipt and sufficiency of which are hereby
acknowledged), the parties hereto hereby agree as follows:

        1. Payment of the Fees. Notwithstanding anything to the contrary in the
License Agreement with respect to the form and timing of payment of the Fees,
the obligations to pay the Fees shall the satisfied in full by compliance by
IMSI with the terms and provisions of this Agreement.

        2. Issuance of the Shares. As soon as reasonable practicable after
execution of this Agreement, IMSI will issue to Greentree, one hundred fifty
thousand dollars ($150,000.00) in shares of IMSI's Common Stock (the "Common
Stock"), no par value (collectively, the "Shares"). The number of shares of IMSI
common stock constituting the Shares will be determined on the day that IMSI is
able to grant fully tradable shares to Greentree. The Shares will be included in
the next Registration Statement to be filed by IMSI on or around 28th February
1999. If a Registration Statement is not filed by IMSI before 19th March, 1999,
this Fee Agreement shall be null and void and the fee terms and conditions of
the Licensing Agreement shall be re-instated sua sponte.

        3. Sale.

        a. Sale. The Shares may be sold by one or more of the following means of
distribution (subject to the provisions of this Agreement): (a) a block trade in
which the broker-dealer so engaged will attempt to sell Shares as agent, but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a broker-dealer as principal and resale by such
broker-dealer for its own account; (c) an over-the-counter distribution in
accordance with the rules of Nasdaq; (d) ordinary brokerage transactions and
transactions in which the broker solicits purchasers; and (e) in privately
negotiated transactions.

        b. Restrictions on Sale. Greentree shall have no restrictions on sale.



<PAGE>   2

        4. Representations, Warranties and Covenants of IMSI. IMSI represents
and warrants to and covenants with Greentree as follows:


                a. Registration. IMSI shall use its reasonable best efforts to
cause the shares of IMSI Common Stock that are issuable pursuant to this Fee
Agreement to be registered on a registration statement (or to be issued pursuant
to a then-effective registration statement) on Form S-3 (or successor form)
promulgated by the Securities and Exchange Commission ("SEC") under the 1933
Act, as soon as reasonably practicable after the Closing. It is the intent of
IMSI to file a registration statement on or around 28th February 1999. Nothing
herein shall require IMSI to separately register the Shares.

                b. At the date the Registration Statement becomes effective
under the Securities Act (the "Effective Date") or the time of effectiveness of
any post-effective amendment to the Registration Statement, at the time the
Prospectus is first filed with the Commission pursuant to Rule 424 (b) of the
Regulations (if a Rule 424 (b) filing is required), at the time any supplement
to or amendment of the Prospectus is filed with the Commission and at the time
any document filed under the Exchange Act is filed, the Registration Statement
and the Prospectus and any amendments thereof and supplements thereto complied
or will comply in all material respects with the applicable provisions of the
Securities Act and the Regulations or the Exchange Act and the respective rules
and regulations thereunder and do not or will not contain an untrue statement of
a material fact and do not or will not omit to state any material fact required
to be stated therein or necessary in order to make the statements therein (i) in
the case of the Registration Statement, not misleading and (ii) in the case of
the Prospectus, in the light of the circumstances under which they were made,
not misleading.

                c. The Shares, when issued and delivered in accordance with this
Agreement, will be duly and validly issued and outstanding, fully paid and
non-assessable and will not have been issued in violation of any preemptive
rights.

                d. If at any time when a prospectus relating to the Shares is
required to be delivered under the Securities Act any event shall occur as a
result of which the Prospectus as then amended or supplemented, in the judgment
of IMSI or Greentree, includes an untrue statement of a material fact or omits
to state any material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, or if it shall be necessary at any time to amend or
supplement the Prospectus or Registration Statement to comply with the
Securities Act or the Regulations, or to file under the Exchange Act so as to
comply therewith any document incorporated by reference in the Registration
Statement or the Prospectus or in any amendment thereof or supplement thereto,
(i) IMSI will notify Greentree promptly and prepare and file with the Commission
an appropriate amendment or supplement (in form and substance satisfactory to
Greentree) which will correct such statement or omission or which will effect
such compliance and will use its best efforts to


<PAGE>   3

have any amendment to the Registration Statement docked declared effective by
the Commission as soon as possible and (ii) Greentree shall suspend trading in
the Shares until (A) such amendment or supplement to the Prospectus has been
filed or (B) any amendment to the Registration Statement has been declared
effective by the Commission.

                e. IMSI will pay all fees and expenses with respect to the
preparation and filing of the Registration Statement and the registration of the
Shares. If however, Greentree requests that the Shares be registered
independently from another IMSI registration ("Accelerated Registration), the
Greentree shall pay all fees and expenses with respect to the preparation and
filing of the Registration Statement and the registration of the Shares that are
a result of such Accelerated Registration.

                f. Upon successful completion of the Registration Statement,
Greentree will release and forever discharge payment of the Fees pursuant to the
terms and conditions of the License Agreement.


        5. Indemnification.

a. IMSI agrees to indemnify and hold harmless Greentree, against any and all
losses, liabilities, claims, damages and expenses incurred (including but not
limited to attorneys' fees), to which it may become subject under the Securities
Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims,
damages or expenses (or actions in respect thereof) arise solely out of any
untrue statement of a material fact contained in the Registration Statement, as
originally filed or any amendment thereof, or the Prospectus, or in any
supplement thereto or amendment thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading;
provided, however, that IMSI shall not be liable to Greentree for any such
losses, liabilities, claims, damages or expenses which arise out of or are based
upon an untrue statement or alleged untrue statement or omission or alleged
omission contained or made in the Registration Statement or the Prospectus or
any amendment thereof or Supplement thereto in reliance upon and in conformity
with information furnished to IMSI by Greentree.

        b. Promptly after receipt by any indemnified party under subsection a.
above of notice of the commencement of any action, such indemnified party shall,
if a claim in respect thereof is to be made against the indemnifying party under
such subsection, notify the party against whom indemnification is to be sought
in writing of the commencement thereof. In case any such action is brought
against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof. Notwithstanding the foregoing,
the indemnified party or parties shall have the right to employ its own counsel
in any such


<PAGE>   4

case, but the fees and expenses of such counsel shall be at the
expense of such indemnified party unless (i) the employment of such counsel
shall have been authorized in writing by the indemnifying party in connection
with the defense of such action, (ii) the indemnifying party shall not have
employed counsel to have charge of the defense of such action within a
reasonable time after notice of commencement of the action, or (iii) such
indemnified party shall have reasonably concluded that there may be defenses
available to it or them which are different from or additional to those
available to the indemnifying party (in which case the indemnifying party shall
not have the right to direct the defense of such action on behalf of the
indemnified party or parties), in any of which events such fees and expenses
shall be borne by the indemnifying party. Anything in this subsection to the
contrary notwithstanding, the indemnifying party shall not be liable for any
settlement of any claim or action effected without its written consent:
provided, however, that such consent was not unreasonably withheld.

        6. Entire Agreement. This Agreement and the License Agreement (to the
extent not inconsistent herewith) constitute the entire agreement between the
parties hereto with respect to the subject matter hereof and supersede all prior
written agreements and negotiations and oral understandings, if any, with
respect thereto. This Agreement may not be amended or supplemented except by an
instrument in writing signed by each of the parties hereto.

                b. At the date the Registration Statement becomes effective
under the Securities Act (the "Effective Date") or the time of effectiveness of
any post-effective amendment to the Registration Statement, at the time the

not misleading.

                c. The Shares, when issued and delivered in accordance with this
Agreement, will be duly and validly issued and outstanding, fully paid and
non-assessable and will not have been issued in violation of any preemptive
rights.

                d. If at any time when a prospectus relating to the Shares is
required to be delivered under the Securities Act any event shall occur as a
result of which the Prospectus as then amended or supplemented, in the judgment
of IMSI or ZEDCOR, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it shall be necessary at any time to amend or
supplement the Prospectus or Registration Statement to comply with the
Securities Act or the Regulations, or to file under the Exchange Act so as to
comply therewith any document incorporated by reference in the Registration
Statement or the Prospectus or in any amendment thereof or supplement thereto,

registration of the Shares that are a result of such Accelerated Registration.

                f. Upon execution of this Agreement, ZEDCOR releases and forever
discharges payment of the Fees pursuant to the terms and conditions of the
Exchange Agreement. The Hold Back Funds shall remain in tact and subject to the
terms and conditions of the Exchange Agreement and any addendum's thereto.

        5. Indemnification.

a. IMSI agrees to indemnify and hold harmless ZEDCOR, against any and all
losses, liabilities, claims, damages and expenses incurred (including but not
limited to attorneys' fees), to which it may become subject under the Securities
Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims,
damages or expenses (or actions in respect thereof) arise solely out of any
untrue statement of a material fact contained in the Registration Statement, as
originally filed or any amendment thereof, or the Prospectus, or in any
supplement thereto or amendment thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading;
provided, however, that IMSI shall not be liable to ZEDCOR for any such losses,
liabilities, claims, damages or expenses which arise out of or are based upon an
untrue statement or alleged untrue statement or omission or alleged omission
contained or made in the Registration Statement or the Prospectus or any
amendment thereof or Supplement thereto in reliance upon and in conformity with

indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the party against whom
indemnification is to be sought in writing of the commencement thereof. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof.
Notwithstanding the foregoing, the indemnified party or parties shall have the
right to employ its own counsel in any such case, but the fees and expenses of
such counsel shall be at the expense of such indemnified party unless (i) the
employment of such counsel shall have been authorized in writing by the
indemnifying party in connection with the defense of such action, (ii) the
indemnifying party shall not have employed counsel to have charge of the defense
of such action within a reasonable time after notice of commencement of the
action, or (iii) such indemnified party shall have reasonably concluded that
there may be defenses available to it or them which are different from or
additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to direct the defense of such action
on behalf of the indemnified party or parties), in any of which events such


<PAGE>   4

fees and expenses shall be borne by the indemnifying party. Anything in this
subsection to the contrary notwithstanding, the indemnifying party shall not be
liable for any settlement of any claim or action effected without its written
consent: provided, however, that such consent was not unreasonably withheld.

        6. Entire Agreement. This Agreement and the License Agreement (to the

and between International Microcomputer Software, Inc. a California corporation
("IMSI"), and Law Offices of Mark Garay, Inc., a law firm ("LAW OFFICES OF MARK
GARAY").

        WHEREAS, IMSI currently owes LAW OFFICES OF MARK GARAY an amount to date
equal to $100,000.00 (the "Initial Attorney Fees") pursuant to a Retainer
between IMSI and LAW OFFICES OF MARK GARAY (the "Retainer"), and

        WHEREAS, IMSI and LAW OFFICES OF MARK GARAY now desire to set forth
certain terms and provisions with respect to the payment by IMSI of the Initial
Attorney Fees:

        NOW, THEREFORE in consideration of the foregoing and for other good and
valuable consideration (the receipt and sufficiency of which are hereby
acknowledged), the parties hereto hereby agree as follows:

1. Payment of the Fees. Notwithstanding anything to the contrary in the Retainer
with respect to the form and timing of payment of the Initial Attorney Fees, the
obligations to pay the Initial Attorney Fees shall the satisfied in full by
compliance by IMSI with the terms and provisions of this Agreement. On the date
that the stock first becomes free to trade on the NASDAQ, or other exchange upon
which it may then be listed ("Valuation Date"). An amount of $100,000 will
become the IMSI account value ("Account Value") at the LAW OFFICES OF MARK
GARAY. The Account Value shall be debited for any fees due and not yet paid to
the LAW OFFICES OF MARK GARAY as of that date. Any surplus in the Account Value,
shall be a credit to be utilized against future fees for work to be performed by
the LAW OFFICES OF MARK GARAY for IMSI. In the event that the fees then due to
the LAW OFFICES OF MARK GARAY total more then the Account Value, IMSI shall
immediately make up the difference between that amount and $100,000 in a lump
sum cash payment to the LAW OFFICES OF MARK GARAY.

        2. Issuance of the Shares. As soon as reasonably practicable after
execution of this Agreement, IMSI will issue to LAW OFFICES OF MARK GARAY,
eleven thousand one hundred twelve (11,112) shares of IMSI's Common Stock (the
"Common Stock"), no par value (collectively, the "Shares") based on a trading
price of nine dollars ($9.00) per share.

        3. Sale.

        a. Sale. The Shares may be sold by one or more of the following means of
distribution (subject to the provisions of this Agreement): (a) a block trade in
which the broker-dealer so engaged will attempt to sell Shares as agent, but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a



                                                                               1

broker-dealer as principal and resale by such broker-dealer for its own account;
(c) an over-the-counter distribution in accordance with the rules of Nasdaq; (d)
ordinary brokerage transactions and transactions in which the broker solicits
purchasers; and (e) in privately negotiated transactions.

        4. Representations, Warranties and Covenants of IMSI. IMSI represents
and warrants to and covenants with LAW OFFICES OF MARK GARAY as follows:

                a. Registration. IMSI shall use its reasonable best efforts to
cause the shares of IMSI Common Stock that are issuable pursuant to this Fee
Agreement to be registered on a registration statement (or to be issued pursuant
to a then-effective registration statement) on Form S-3 (or successor form)
promulgated by the Securities and Exchange Commission ("SEC") under the 1933
Act, as soon as reasonably practicable after the Closing. IMSI expects to file a
Registration Statement on or about 28th February 1999. Nothing herein shall
require IMSI to seperately register the Shares.

                b. At the date the Registration Statement becomes effective
under the Securities Act (the "Effective Date") or the time of effectiveness of
any post-effective amendment to the Registration Statement, at the time the
Prospectus is first filed with the Commission pursuant to Rule 424 (b) of the
Regulations (if a Rule 424 (b) filing is required), at the time any supplement
to or amendment of the Prospectus is filed with the Commission and at the time
any document filed under the Exchange Act is filed, the Registration Statement
and the Prospectus and any amendments thereof and supplements thereto complied
or will comply in all material respects with the applicable provisions of the
Securities Act and the Regulations or the Exchange Act and the respective rules
and regulations thereunder and do not or will not contain an untrue statement of
a material fact and do not or will not omit to state any material fact required
to be stated therein or necessary in order to make the statements therein (i) in
the case of the Registration Statement, not misleading and (ii) in the case of
the Prospectus, in the light of the circumstances under which they were made,
not misleading.

                c. The Shares, when issued and delivered in accordance with this
Agreement, will be duly and validly issued and outstanding, fully paid and
non-assessable and will not have been issued in violation of any preemptive
rights.

                d. If at any time when a prospectus relating to the Shares is
required to be delivered under the Securities Act any event shall occur as a
result of which the Prospectus as then amended or supplemented, in the judgment
of IMSI or LAW OFFICES OF MARK GARAY, includes an untrue statement of a material
fact or omits to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, or if it shall be necessary at any
time to amend or supplement the Prospectus or Registration Statement to comply
with the Securities Act or the Regulations, or to file under the Exchange Act so
as to comply therewith any document incorporated by reference in the
Registration Statement or the Prospectus or in any amendment thereof or
supplement



                                                                               2
<PAGE>   3

thereto, (i) IMSI will notify LAW OFFICES OF MARK GARAY promptly and prepare and
file with the Commission an appropriate amendment or supplement (in form and
substance satisfactory to LAW OFFICES OF MARK GARAY) which will correct such
statement or omission or which will effect such compliance and will use its best
efforts to have any amendment to the Registration Statement docked declared
effective by the Commission as soon as possible and (ii) LAW OFFICES OF MARK
GARAY shall suspend trading in the Shares until (A) such amendment or supplement
to the Prospectus has been filed or (B) any amendment to the Registration
Statement has been declared effective by the Commission.

                e. IMSI will pay all fees and expenses with respect to the
preparation and filing of the Registration Statement and the registration of the
Shares. If however, LAW OFFICES OF MARK GARAY requests that the Shares be
registered independently from another IMSI registration ("Accelerated
Registration), then LAW OFFICES OF MARK GARAY shall pay all fees and expenses
with respect to the preparation and filing of the Registration Statement and the
registration of the Shares that are a result of such Accelerated Registration.

        5. Indemnification.

a. IMSI agrees to indemnify and hold harmless LAW OFFICES OF MARK GARAY, against
any and all losses, liabilities, claims, damages and expenses incurred
(including but not limited to attorneys' fees), to which it may become subject
under the Securities Act, the Exchange Act or otherwise, insofar as such losses,
liabilities, claims, damages or expenses (or actions in respect thereof) arise
solely out of any untrue statement of a material fact contained in the
Registration Statement, as originally filed or any amendment thereof, or the
Prospectus, or in any supplement thereto or amendment thereof, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading; provided, however, that IMSI shall not be liable to LAW OFFICES
OF MARK GARAY for any such losses, liabilities, claims, damages or expenses
which arise out of or are based upon an untrue statement or alleged untrue
statement or omission or alleged omission contained or made in the Registration
Statement or the Prospectus or any amendment thereof or Supplement thereto in
reliance upon and in conformity with information furnished to IMSI by LAW
OFFICES OF MARK GARAY.

                b. Promptly after receipt by any indemnified party under
subsection a. above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the party against whom
indemnification is to be sought in writing of the commencement thereof. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof.
Notwithstanding the foregoing, the



                                                                               3
<PAGE>   4

indemnified party or parties shall have the right to employ its own counsel in
any such case, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the employment of such counsel shall have
been authorized in writing by the indemnifying party in connection with the
defense of such action, (ii) the indemnifying party shall not have employed
counsel to have charge of the defense of such action within a reasonable time
after notice of commencement of the action, or (iii) such indemnified party
shall have reasonably concluded that there may be defenses available to it or
them which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to direct the defense of such action on behalf of the indemnified party or
parties), in any of which events such fees and expenses shall be borne by the
indemnifying party. Anything in this subsection to the contrary notwithstanding,
the indemnifying party shall not be liable for any settlement of any claim or
action effected without its written consent: provided, however, that such
consent was not unreasonably withheld.

        6. Entire Agreement. This Agreement and the retainer (to the extent not
inconsistent herewith) constitute the entire agreement between the parties
hereto with respect to the subject matter hereof and supersede all prior written
agreements and negotiations and oral understandings, if any, with respect
thereto. This Agreement may not be amended or supplemented except by an
instrument in writing signed by each of the parties hereto.

        2. SUBSCRIPTION FOR, PURCHASE AND EXERCISE OF WARRANT; ORIGINAL ISSUE
DISCOUNT.

                2.1 PURCHASE OF WARRANT. Subject to the terms and conditions
hereinafter set forth, the Purchaser hereby subscribes for and purchases, and
the Company hereby sells to the Purchaser, for good and valuable consideration,
the receipt of which is hereby acknowledged, the Warrant.

                2.2 THE TIME AND PLACE OF THE CLOSING. The Closing of the
transactions provided for in this Agreement (the "CLOSING") shall be held at
10:00 a.m., local time, on November 3, 1998 at the offices of Cooley Godward
LLP, Five Palo Alto Square, Palo Alto, California 94306, or at such other time
and place as the Purchaser and the Company shall agree.

                2.3 CLOSING OF THE PURCHASE OF THE WARRANT. At the Closing, the
Company will execute and deliver to the Purchaser the Warrant which shall be
issued in the Purchaser's name.

                2.4 CONDITIONS TO THE OBLIGATIONS OF THE PURCHASER AND THE
COMPANY. The obligations of the Purchaser and the Company hereunder shall be
subject to the following conditions:

                        (a) The representations and warranties made herein to
the Purchaser or the Company by the other party shall be true and correct in all
material respects at and as of the date of the Closing.

                        (b) The Purchaser and the Company shall have entered
into the Registration Rights Agreement in the form attached hereto as EXHIBIT B
(the "REGISTRATION RIGHTS AGREEMENT").

                2.5 ORIGINAL ISSUE DISCOUNT. The Company and the Purchaser
hereby acknowledge and agree that the Warrant is part of an investment unit
within the meaning of Section 1273 (c) (2) of the Internal Revenue Code of 1986,
as amended, which investment unit includes all Credit Extensions (as defined in
the Loan Agreement) made pursuant to the Loan Agreement up to the maximum amount
of the Term Loan (as defined in the Loan Agreement). The Company and the
Purchaser agree that the fair market value of the Warrant is less than the DE
MINIMIS threshold for reporting income and expense relating thereto on a current
basis. Therefore, the Company and the Purchaser shall prepare their respective
federal income tax returns in a manner consistent with the foregoing agreement
and, pursuant to Treas. Reg. Section 1.1273, the original issue discount on the
Credit Extensions shall be considered to be zero.

        3. PURCHASER'S REPRESENTATIONS, WARRANTIES AND AGREEMENTS. The Purchaser
hereby represents, warrants and covenants to the Company as follows:

                3.1 NO RESALES. The Purchaser will acquire the Warrant for
investment solely for its own account and not with a view to, or for resale in
connection with, the distribution or other disposition thereof except in
compliance with the provisions of Rule 144A under the Securities Act of 1933, as
amended (the "ACT"). The Purchaser agrees and acknowledges that it will not,
directly or indirectly, offer, transfer, sell, assign, pledge, hypothecate or
otherwise dispose of (referred to hereinafter as a "TRANSFER") its Warrant


<PAGE>   3

Shares unless (i) such Transfer is pursuant to an effective registration
statement under the Act and complies with all applicable state securities laws,
or (ii) counsel for the Purchaser (which counsel shall be reasonably acceptable
to the Company) shall have furnished the Company with an opinion, reasonably
satisfactory in form and substance to the Company, to the effect that no such
registration is required because of the availability of an exemption from
registration under the Act and that the Transfer is exempt from all applicable
state securities laws, except that no such opinion shall be required (y) in
connection with a Transfer by the Purchaser to any affiliate of the Purchaser or
(z) in connection with a Transfer where the transferee simultaneously becomes a
lender under the Loan Agreement and makes the representations and warranties
contained in this Section 3. No Transfer of the Warrant or the Warrant Shares in
violation of this Agreement shall be made or recorded on the books of the
Company, and any such Transfer shall be void and of no effect

                3.2 LEGENDS. The Warrant shall bear legends in substantially the
following form:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
        UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT") OR ANY STATE
        SECURITIES LAWS AND MAY NOT BE: TRANSFERRED, SOLD, ASSIGNED, PLEDGED,
        HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS (A) SUCH TRANSFER IS
        PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND ANY
        APPLICABLE STATE SECURITIES LAWS, OR (B) THE COMPANY HAS BEEN FURNISHED
        WITH A SATISFACTORY OPINION OF COUNSEL FOR THE PURCHASER THAT SUCH
        TRANSFER IS EXEMPT FROM THE PROVISIONS OF SECTION 5 OF THE ACT, THE
        RULES AND REGULATIONS IN EFFECT THEREUNDER AND ANY APPLICABLE STATE
        SECURITIES LAWS."

The Warrant, and the Warrant Shares issuable in respect thereof, shall bear
legends in substantially the following form:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS
        AND CONDITIONS OF A CERTAIN WARRANT SUBSCRIPTION AGREEMENT (THE "WARRANT
        SUBSCRIPTION AGREEMENT") AND REGISTRATION RIGHTS AGREEMENT (THE
        "REGISTRATION RIGHTS AGREEMENT"), EACH DATED AS OF OCTOBER [___], 1998,
        BY AND BETWEEN THE WARRANT PURCHASER AND THE COMPANY. COPIES OF SUCH
        AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE
        COMPANY."

                3.3 WARRANT AND WARRANT SHARES UNREGISTERED. The Purchaser
acknowledges with respect to the Purchaser's Warrant and Warrant Shares that the
Purchaser has been advised that:

                        (a) the Warrant has not been registered under the Act or
qualified under the applicable securities laws of any state;

                        (b) except as otherwise provided herein, the Warrant
must be held indefinitely and the Purchaser must continue to bear the economic
risk of the investment in the Warrant and the Warrant Shares unless the sale
thereof is subsequently registered under the Act and qualified under applicable
state securities laws or an exemption from such registration or qualification is
available;

                        (c) it is not anticipated that there will be any public
market for the Warrant;


<PAGE>   4

                        (d) Rule 144 promulgated under the Act ("RULE 144") is
not presently available with respect to the sale of the Warrant, and the Company
has made no covenant to make Rule 144 available (except as provided in SECTION
4.2 hereof);

                        (e) when and if the Warrant or the Warrant Shares may be
disposed of without registration in reliance on Rule 144, such disposition can
be made only in limited amounts in accordance with the terms and conditions of
Rule 144;

                        (f) if the Rule 144 exemption is not available, public
sale of the Warrant or the Warrant Shares without registration will require
compliance with Regulation A promulgated under the Act or some other exemption
under the Act and compliance with applicable state securities laws;

                        (g) appropriate restrictive legends in the form
heretofore set forth shall be placed on each of the Warrant and the Warrant
Shares; and

                        (h) a notation shall be made in the appropriate records
of the Company indicating that the Warrant is subject to restrictions on
transfer and, if the Company should at some time in the future engage the
services of a transfer agent, appropriate transfer restrictions will be issued
to such transfer agent with respect to the Warrant.

                3.4 COMPLIANCE WITH RULE 144. If the Warrant or any Warrant
Shares are disposed of in accordance with Rule 144 under the Act, the Purchaser
shall deliver to the Company at or prior to the time of such disposition an
executed copy of Form 144 (if required by Rule 144) and such other documentation
as the Company may reasonably require in connection with such sale.

                3.5 ADDITIONAL REPRESENTATIONS. The Purchaser further represents
and warrants to the Company that:

        4. THE COMPANY'S REPRESENTATIONS, WARRANTIES AND AGREEMENTS.

                4.1 THE COMPANY'S REPRESENTATIONS AND WARRANTIES. The Company
represents and warrants that:

                        (a) ORGANIZATION, STANDING AND QUALIFICATION. The
Company is a corporation duly organized, validly existing and in good standing
under the laws of the State of California; has all requisite power and authority
to own or lease and operate its properties and to carry on its business as now
conducted and as proposed to be conducted after the funds are advanced under the
Loan Agreement; and is duly qualified or licensed to do business as a foreign
corporation in good standing in all jurisdictions in which it owns or leases
property or in which the conduct of its business requires it to so qualify or be
licensed, except for such jurisdictions where the failure to so qualify or be
licensed would not have a material adverse effect on the business or financial
condition of the Company.

                        (b) AUTHORITY. The Company has all requisite power and
authority to enter into and perform all of its obligations under this Agreement,
to issue the Warrant and the Warrant Shares and to carry out the transactions
contemplated hereby.



                                       5
<PAGE>   6

                        (c) DUE AUTHORIZATION. The Company has taken all
corporate actions necessary to authorize it to enter into and perform its
obligations under this Agreement, to issue the Warrant and the Warrant Shares
and to consummate the transactions contemplated hereby. This Agreement is the
legal, valid and binding obligation of the Company, enforceable in accordance
with its terms, except for (i) the effect upon this Agreement of bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and other similar
laws relating to or affecting the rights of creditors generally and (ii)
limitations imposed by equitable principles or principles of public policy upon
the specific enforceability of any of the remedies, covenants or other
provisions of this Agreement and upon the availability of injunctive relief or
other equitable remedies.

                        (d) CAPITALIZATION OF COMPANY. The Company's capital
stock is divided into Common Stock and preferred stock ("PREFERRED STOCK"). The
authorized capital stock of the Company consists of 20,000,000 shares of Series
A Preferred Stock, of which, immediately after the date of the Closing, no
shares are issued or outstanding, and 300,000,000 shares of Common Stock, of
which, immediately after the date of the Closing, 6,278,881 shares will be
outstanding on a fully diluted basis, taking into account all outstanding
warrants, options and other rights to purchase the Common Stock). When the
Warrant to be purchased by the Purchaser hereunder at the Closing has been
delivered as provided herein, the Warrant Shares (i) together with all
outstanding shares of Common Stock, Preferred Stock and shares of Common Stock
issuable upon exercise of all outstanding Options (as defined below) of the
Company will not exceed the number of shares that have been authorized by the
Company's Articles of Incorporation, (ii) will have been duly authorized to be
issued by the Company's board of directors, (iii) will, upon payment therefor in
accordance with the terms of the Warrant, be duly and validly issued, fully paid
and nonassessable and (iv) will have been reserved for issuance pursuant to the
terms of the Warrant.

                        (e) NO ADJUSTMENT OF OTHER SHARES ON ISSUANCE. Neither
the issuance nor the exercise of the Warrant will cause the rate at which any of
the Company's outstanding securities are ultimately convertible into Common
Stock to change, nor will such issuance or exercise invoke any "antidilution"
feature of any of the Company's outstanding securities or rights to purchase
securities.

                4.2 RULE 144. The Company agrees that it will perform each of it
obligations under the Registration Rights Agreement as set forth therein and
will use its best efforts to file in a timely manner all reports required to be
filed by it pursuant to the Securities Exchange Act of 1934, as amended (the
"EXCHANGE ACT") and, upon the request of the Purchaser, will furnish the
Purchaser with such reports so that the Purchaser may effect routine sales
pursuant to Rule 144 and Rule 144A (if applicable) under the Act or any similar
rule or regulations hereafter adopted by the Securities and Exchange Commission
(the "SEC").

                4.3 PURCHASER'S PERCENTAGE OWNERSHIP. The Company hereby
represents and warrants that the initial 30,000 Warrant Shares in respect of the
Warrant currently represent that number of shares representing approximately a
0.5% interest in the Company's equity capital on a fully diluted basis (after
giving effect to the exercise of all options, warrants, and convertible
securities assuming all antidilution adjustments have been made and all options
authorized for grant, whether or not granted, have been granted).

        5. REGISTRATION RIGHTS. The Purchaser shall have registration rights
relating to the Warrant and the applicable Warrant Shares as set forth in the
Registration Rights Agreement.



                                       6

                6.1 NO CHANGE OF FISCAL YEAR. Until the Warrant has been fully

Exchange Act and the rules and regulations promulgated thereunder and to provide
copies of such reports to Purchaser promptly following such filing and within 30
days prior to the end of each of its fiscal years, shall provide financial
projections covering the period through at least the end of the next fiscal
year; PROVIDED, HOWEVER, that the Company shall not be required to supply any
information to the Purchaser which duplicates information already supplied to
the Purchaser under the Loan Agreement. In addition, the Company shall provide
the Purchaser with all of the information which the Company provides generally
to the holders of Common Stock. The Purchaser shall have standard inspection

respective heirs, legal representatives, successors and assigns and, without
limiting the generality of the foregoing, the Company may assign this Agreement

Company or a sale of all or substantially all of the assets of the Company.

                6.5 AMENDMENT. This Agreement may be amended only by a written

                                  FEE AGREEMENT

        This FEE AGREEMENT (the "Agreement") dated as of 11th January 1999, by
and between International Microcomputer Software, Inc. ("IMSI"), and HomeStyles,
Inc., ("HOMESTYLES").

        WHEREAS, IMSI currently owes HOMESTYLES an amount to date equal to
$90,000 (the "Current Royalty Fees") pursuant to a Licensing Agreement between
IMSI and HOMESTYLES (the "License Agreement"), and

        WHEREAS, IMSI and HOMESTYLES now desire to set forth certain terms and
provisions with respect to the payment by IMSI of the Current Royalty Fees:

        NOW, THEREFORE in consideration of the foregoing and for other good and
valuable consideration (the receipt and sufficiency of which are hereby
acknowledged), the parties hereto hereby agree as follows:

        1. Payment of the Fees. Notwithstanding anything to the contrary in the
License Agreement with respect to the form and timing of payment of the Current
Royalty Fees, the obligation to pay the Current Royalty Fees shall the satisfied
in full by compliance by IMSI with the terms and provisions of this Agreement.

        2. Issuance of the Shares. As soon as reasonably practicable after
execution of this Agreement, IMSI will issue to HOMESTYLES, ten thousand (10,000
shares of IMSI's Common Stock (the "Common Stock"), no par value (collectively,
the "Shares") based on a trading price of nine dollars ($9.00) per share.

        3. Sale.

        a. Sale. The Shares may be sold by one or more of the following means of
distribution (subject to the provisions of this Agreement): (a) a block trade in
which the brokerdealer so engaged will attempt to sell Shares as agent, but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a brokerdealer as principal and resale by such
broker-dealer for its own account; (c) an overthecounter distribution in
accordance with the rules of Nasdaq; (d) ordinary brokerage transactions and
transactions in which the broker solicits purchasers; and (e) in privately
negotiated transactions.

        4. Representations, Warranties and Covenants of IMSI. IMSI represents
and warrants to and covenants with HOMESTYLES as follows:

                a. Registration. IMSI shall use its reasonable best efforts to
cause the shares of IMSI Common Stock that are issuable pursuant to this Fee
Agreement to be registered on a registration statement (or to be issued pursuant
to a then-effective registration statement) on Form S-3 (or successor form)
promulgated by the Securities


<PAGE>   2

and License Commission ("SEC") under the 1933 Act, as soon as reasonably
practicable after the Closing. IMSI expects to file a Registration Statement on
or about March 15 1999. Nothing herein shall require IMSI to seperately register
the Shares.

                b. At the date the Registration Statement becomes effective
under the Securities Act (the "Effective Date") or the time of effectiveness of
any posteffective amendment to the Registration Statement, at the time the
Prospectus is first filed with the Commission pursuant to Rule 424 (b) of the
Regulations (if a Rule 424 (b) filing is required), at the time any supplement
to or amendment of the Prospectus is filed with the Commission and at the time
any document filed under the License Act is filed, the Registration Statement
and the Prospectus and any amendments thereof and supplements thereto complied
or will comply in all material respects with the applicable provisions of the
Securities Act and the Regulations or the License Act and the respective rules
and regulations thereunder and do not or will not contain an untrue statement of
a material fact and do not or will not omit to state any material fact required
to be stated therein or necessary in order to make the statements therein (i) in
the case of the Registration Statement, not misleading and (ii) in the case of
the Prospectus, in the light of the circumstances under which they were made,
not misleading.

                c. The Shares, when issued and delivered in accordance with this
Agreement, will be duly and validly issued and outstanding, fully paid and
non-assessable and will not have been issued in violation of any preemptive
rights.

                d. If at any time when a prospectus relating to the Shares is
required to be delivered under the Securities Act any event shall occur as a
result of which the Prospectus as then amended or supplemented, in the judgment
of IMSI or HOMESTYLES, includes an untrue statement of a material fact or omits
to state any material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, or if it shall be necessary at any time to amend or
supplement the Prospectus or Registration Statement to comply with the
Securities Act or the Regulations, or to file under the License Act so as to
comply therewith any document incorporated by reference in the Registration
Statement or the Prospectus or in any amendment thereof or supplement thereto,
(i) IMSI will notify HOMESTYLES promptly and prepare and file with the
Commission an appropriate amendment or supplement (in form and substance
satisfactory to HOMESTYLES) which will correct such statement or omission or
which will effect such compliance and will use its best efforts to have any
amendment to the Registration Statement docked declared effective by the
Commission as soon as possible and (ii) HOMESTYLES shall suspend trading in the
Shares until (A) such amendment or supplement to the Prospectus has been filed
or (B) any amendment to the Registration Statement has been declared effective
by the Commission.

                e. IMSI will pay all fees and expenses with respect to the
preparation and filing of the Registration Statement and the registration of the
Shares. If however, HOMESTYLES requests that the Shares be registered
independently from another IMSI


<PAGE>   3
registration ("Accelerated Registration"), then HOMESTYLES shall pay all fees
and expenses with respect to the preparation and filing of the Registration
Statement and the registration of the Shares that are a result of such
Accelerated Registration.

                f. Upon execution of this Agreement, HOMESTYLES releases and
forever discharges payment of the Current Royalty Fees pursuant to the terms and
conditions of the License Agreement.

        5. Indemnification.

a. IMSI agrees to indemnify and hold harmless HOMESTYLES, against any and all
losses, liabilities, claims, damages and expenses incurred (including but not
limited to attorneys' fees), to which it may become subject under the Securities
Act, the License Act or otherwise, insofar as such losses, liabilities, claims,
damages or expenses (or actions in respect thereof) arise solely out of any
untrue statement of a material fact contained in the Registration Statement, as
originally filed or any amendment thereof, or the Prospectus, or in any
supplement thereto or amendment thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading;
provided, however, that IMSI shall not be liable to HOMESTYLES for any such
losses, liabilities, claims, damages or expenses which arise out of or are based
upon an untrue statement or alleged untrue statement or omission or alleged
omission contained or made in the Registration Statement or the Prospectus or
any amendment thereof or Supplement thereto in reliance upon and in conformity
with information furnished to IMSI by HOMESTYLES.

                b. Promptly after receipt by any indemnified party under
subsection a. above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the party against whom
indemnification is to be sought in writing of the commencement thereof. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof.
Notwithstanding the foregoing, the indemnified party or parties shall have the
right to employ its own counsel in any such case, but the fees and expenses of
such counsel shall be at the expense of such indemnified party unless (i) the
employment of such counsel shall have been authorized in writing by the
indemnifying party in connection with the defense of such action, (ii) the
indemnifying party shall not have employed counsel to have charge of the defense
of such action within a reasonable time after notice of commencement of the
action, or (iii) such indemnified party shall have reasonably concluded that
there may be defenses available to it or them which are different from or
additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to direct the defense of such action
on behalf of the indemnified party or parties), in any of which events such


<PAGE>   4

fees and expenses shall be borne by the indemnifying party. Anything in this
subsection to the contrary notwithstanding, the indemnifying party shall not be
liable for any settlement of any claim or action effected without its written
consent: provided, however, that such consent was not unreasonably withheld.

        6. Entire Agreement. This Agreement and the retainer (to the extent not
inconsistent herewith) constitute the entire agreement between the parties
hereto with respect to the subject matter hereof and supersede all prior written

                                     FEE AGREEMENT

        This FEE AGREEMENT (the "Agreement") dated as of 3/1/99, by and between
International Microcomputer Software, Inc. a California corporation ("IMSI"),
and GATEWAY Acceptance, ("GATEWAY").

        WHEREAS, IMSI currently owes GATEWAY an amount equal to $72,000.00 (the
"Fees") pursuant to a Manufacturing Agreement (the "Manufacturing Agreement"),
and

        WHEREAS, IMSI and GATEWAY now desire to set forth certain terms and
provisions with respect to the payment by IMSI of the Fees:

        NOW, THEREFORE in consideration of the foregoing and for other good and
valuable consideration (the receipt and sufficiency of which are hereby
acknowledged), the parties hereto hereby agree as follows:

        1. Payment of the Fees. Notwithstanding anything to the contrary in the
Manufacturing Agreement with respect to the form and timing of payment of the
Fees, the obligations to pay the Fees shall the satisfied in full by compliance
by IMSI with the terms and provisions of this Agreement.

        2. Issuance of the Shares. As soon as reasonably practicable after
execution of this Agreement, IMSI will issue to GATEWAY eight thousand (8,000)
shares of IMSI's Common Stock (the "Common Stock"), no par value (collectively,
the "Shares") based on a trading price of $9.00 per share.

        3. Sale.

        a. Sale. The Shares may be sold by one or more of the following means of
distribution (subject to the provisions of this Agreement): (a) a block trade in
which the broker-dealer so engaged will attempt to sell Shares as agent, but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a broker-dealer as principal and resale by such
broker-dealer for its own account; (c) an over-the-counter distribution in
accordance with the rules of Nasdaq; (d) ordinary brokerage transactions and
transactions in which the broker solicits purchasers; and (e) in privately
negotiated transactions.

        4. Representations, Warranties and Covenants of IMSI. IMSI represents
and warrants to and covenants with GATEWAY as follows:

                a. Registration. IMSI shall use its reasonable best efforts to
cause the shares of IMSI Common Stock that are issuable pursuant to this Fee
Agreement to be registered on a registration statement (or to be issued pursuant
to a then-effective registration statement) on Form S-3 (or successor form)
promulgated by the Securities


<PAGE>   2

and EGATEWAYchange Commission ("SEC") under the 1933 Act, as soon as reasonably
practicable after the Closing. IMSI expects to file a Registration Statement on
or about 28th February 1999. Nothing herein shall require IMSI to seperately
register the Shares.

                b. At the date the Registration Statement becomes effective
under the Securities Act (the "Effective Date") or the time of effectiveness of
any post-effective amendment to the Registration Statement, at the time the
Prospectus is first filed with the Commission pursuant to Rule 424 (b) of the
Regulations (if a Rule 424 (b) filing is required), at the time any supplement
to or amendment of the Prospectus is filed with the Commission and at the time
any document filed under the Manufacturing Act is filed, the Registration
Statement and the Prospectus and any amendments thereof and supplements thereto
complied or will comply in all material respects with the applicable provisions
of the Securities Act and the Regulations or the Manufacturing Act and the
respective rules and regulations thereunder and do not or will not contain an
untrue statement of a material fact and do not or will not omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein (i) in the case of the Registration Statement, not misleading
and (ii) in the case of the Prospectus, in the light of the circumstances under
which they were made, not misleading.

                c. The Shares, when issued and delivered in accordance with this
Agreement, will be duly and validly issued and outstanding, fully paid and
non-assessable and will not have been issued in violation of any preemptive
rights.

                d. If at any time when a prospectus relating to the Shares is
required to be delivered under the Securities Act any event shall occur as a
result of which the Prospectus as then amended or supplemented, in the judgment
of IMSI or GATEWAY, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it shall be necessary at any time to amend or
supplement the Prospectus or Registration Statement to comply with the
Securities Act or the Regulations, or to file under the Manufacturing Act so as
to comply therewith any document incorporated by reference in the Registration
Statement or the Prospectus or in any amendment thereof or supplement thereto,
(i) IMSI will notify GATEWAY promptly and prepare and file with the Commission
an appropriate amendment or supplement (in form and substance satisfactory to
GATEWAY) which will correct such statement or omission or which will effect such
compliance and will use its best efforts to have any amendment to the
Registration Statement docked declared effective by the Commission as soon as
possible and (ii) GATEWAY shall suspend trading in the Shares until (A) such
amendment or supplement to the Prospectus has been filed or (B) any amendment to
the Registration Statement has been declared effective by the Commission.

                e. IMSI will pay all fees and expenses with respect to the
preparation and filing of the Registration Statement and the registration of the
Shares. If however,


<PAGE>   3

GATEWAY requests that the Shares be registered independently from another IMSI
registration ("Accelerated Registration), then GATEWAY shall pay all fees and
expenses with respect to the preparation and filing of the Registration
Statement and the registration of the Shares that are a result of such
Accelerated Registration.

                f. Upon execution of this Agreement, GATEWAY releases and
forever discharges payment of the Fees pursuant to the terms and conditions of
the Manufacturing Agreement. The Hold Back Funds shall remain in tact and
subject to the terms and conditions of the Manufacturing Agreement and any
addendum's thereto.

        5. Indemnification.

a. IMSI agrees to indemnify and hold harmless GATEWAY, against any and all
losses, liabilities, claims, damages and expenses incurred (including but not
limited to attorneys' fees), to which it may become subject under the Securities
Act, the Manufacturing Act or otherwise, insofar as such losses, liabilities,
claims, damages or expenses (or actions in respect thereof) arise solely out of
any untrue statement of a material fact contained in the Registration Statement,
as originally filed or any amendment thereof, or the Prospectus, or in any
supplement thereto or amendment thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading;
provided, however, that IMSI shall not be liable to GATEWAY for any such losses,
liabilities, claims, damages or expenses which arise out of or are based upon an
untrue statement or alleged untrue statement or omission or alleged omission
contained or made in the Registration Statement or the Prospectus or any
amendment thereof or Supplement thereto in reliance upon and in conformity with
information furnished to IMSI by GATEWAY.

                b. Promptly after receipt by any indemnified party under
subsection a. above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the party against whom
indemnification is to be sought in writing of the commencement thereof. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof.
Notwithstanding the foregoing, the indemnified party or parties shall have the
right to employ its own counsel in any such case, but the fees and expenses of
such counsel shall be at the expense of such indemnified party unless (i) the
employment of such counsel shall have been authorized in writing by the
indemnifying party in connection with the defense of such action, (ii) the
indemnifying party shall not have employed counsel to have charge of the defense
of such action within a reasonable time after notice of commencement of the
action, or (iii) such indemnified party shall have reasonably concluded that
there may be defenses available to it or them which are different from or
additional to those available to the indemnifying


<PAGE>   4

party (in which case the indemnifying party shall not have the right to direct
the defense of such action on behalf of the indemnified party or parties), in
any of which events such fees and expenses shall be borne by the indemnifying
party. Anything in this subsection to the contrary notwithstanding, the
indemnifying party shall not be liable for any settlement of any claim or action
effected without its written consent: provided, however, that such consent was
not unreasonably withheld.

        6. Entire Agreement. This Agreement and the Manufacturing Agreement (to
the extent not inconsistent herewith) constitute the entire agreement between
the parties hereto with respect to the subject matter hereof and supersede all
prior written agreements and negotiations and oral understandings, if any, with
respect thereto. This Agreement may not be amended or supplemented except by an
instrument in writing signed by each of the parties hereto.

                                 FEE AGREEMENT

     WHEREAS, IMSI and SPATIAL TECHNOLOGY now desire to set forth certain terms
and provisions with respect to the payment by IMSI of the Fees:

     NOW, THEREFORE in consideration of the foregoing and for other good and
valuable consideration (the receipt and sufficiency of which are hereby
acknowledged), the parties hereto hereby agree as follows:

     1. Payment of the Fees. Notwithstanding anything to the contrary in the

($9.00) per share.

     3. Sale.

        a.  Sale.  The Shares may be sold by one or more of the following means
of distribution (subject to the provisions of this Agreement): (a) a block
trade in which the brokerdealer so engaged will attempt to sell Shares as
agent, but may position and resell a portion of the block as principal to

resale by such broker-dealer for its own account; (c) an over-the-counter
distribution in accordance with the rules of NASDAQ; (d) ordinary brokerage

     4.  Representations, Warranties and Covenants of IMSI. IMSI represents and
warrants to and covenants with SPATIAL TECHNOLOGY as follows:

         a.  Registration. IMSI shall use its reasonable best efforts to cause
the Shares that are issuable pursuant to this Fee Agreement to be registered on

under the 1993 Act ("Securities Act"), as soon as reasonably practicable after
the Closing. IMSI currently expects to file a Form S-3 on or around 5/5/99.
Nothing herein shall require IMSI to separately register the Shares.

          b.   At the date the Registration Statement becomes effective under
the Securities Act or the time of effectiveness of any posteffective amendment
to the Registration Statement (the "Effective Date"), at the time the Prospectus
is first filed with the SEC pursuant to Rule 424(b) of the regulations
promulgated thereunder (if a Rule 424(b) filing is required), at the time any
supplement to or amendment of the Prospectus is filed with the SEC and at the
time any document filed under the Securities Act is filed, the Registration
Statement and the Prospectus and any amendments thereof and supplements thereto
complied or will comply in all material respects with the applicable provisions
of the Securities Act and the regulations promulgated thereunder or the
Securities Act and the respective rules and regulations thereunder and do not or
will not contain an untrue statement of a material fact and do not or will not
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein (i) in the case of the Registration
Statement, not misleading and (ii) in the case of the Prospectus, in the light
of the circumstances under which they were made, not misleading.

          c.   The Shares, when issued and delivered in accordance with this
Agreement, will be duly and validly issued and outstanding, fully paid and
non-assessable and will not have been issued in violation of any preemptive
rights and will not be subject to any restrictions, except as may be imposed by
applicable law, except that the share certificate(s) will bear restrictive
legend that the shares are not registered until such time as the shares are
registered.

          d.   IMSI is a corporation duly organized, validly existing and in
good standing under the laws of the State of California and has all necessary

          e.   IMSI has the full legal right, power and authority to enter into
this Agreement. All proceedings required to be taken by IMSI to authorize the
execution, delivery and performance of this Agreement have been properly taken.
This Agreement constitutes the valid and binding obligation of IMSI,

general application relating to bankruptcy, insolvency and the relief of
debtors and (ii) rules of law governing specific performance, injunctive relief
and other equitable remedies. The execution, delivery or performance of this
Agreement by IMSI will not, with or without the giving of notice or the passage
of time, or both, conflict with, result in a material breach of, or a default,
right to accelerate or loss of rights under, any provision of IMSI's corporate
documents or any agreement to which IMSI is a party.




<PAGE>   3
            e.    If at any time when a prospectus relating to the Shares is
required to be delivered under the Securities Act any event shall occur as a
result of which the Prospectus as then amended or supplemented, in the judgment
of IMSI or SPATIAL TECHNOLOGY, includes an untrue statement of a material fact
or omits to state any material fact required to be stated therein or necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, or if it shall be necessary at any time to amend
or supplement the Prospectus or Registration Statement to comply with the
Securities Act or the Regulations, or to file under the Securities Act so as to
comply therewith any document incorporated by reference in the Registration
Statement or the prospectus or in any amendment thereof or supplement thereto,
(i) IMSI will notify SPATIAL TECHNOLOGY promptly and prepare and file with the
SEC an appropriate amendment or supplement (in form and substance satisfactory
to SPATIAL TECHNOLOGY) which will correct such statement or omission or which
will effect such compliance and will use its best efforts to have any amendment
to the Registration Statement docked declared effective by the SEC as soon as
possible and (ii) SPATIAL TECHNOLOGY shall suspend trading in the Shares until
(A) such amendment or supplement to the Prospectus has been filed or (B) any
amendment to the Registration Statement has been declared effective by the SEC.

            f.    IMSI will pay all fees and expenses with respect to the
preparation and filing of the Registration Statement and the registration of the

independently from another IMSI registration ("Accelerated Registration), then
SPATIAL TECHNOLOGY shall pay all fees and expenses with respect to the
preparation and filing of the Registration Statement and the registration of the
Shares that are a result of such Accelerated Registration.

            g.    Upon execution of this Agreement, SPATIAL TECHNOLOGY releases
and forever discharges payment of the Fees pursuant to the terms and conditions
of the Retainer.

            h.    IMSI's filings with the SEC as of the date of such filing and
in the light of the circumstances under which such filings were made (i)
complied in all material respects with the applicable requirements of the
Securities Act or the Securities Exchange Act of 1934 (as the case may be); and
(ii) when read together as a whole and as updated by subsequent reports or
filings made prior to the date of this Agreement, do not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.

            i.    The [consolidated] financial statements contained in the SEC
Documents: (i) complied as to form in all material respects with the published
rules and regulations of the SEC applicable thereto; (ii) were prepared in
accordance with generally accepted accounting principles applied on a consistent
basis throughout the periods covered, except as may be indicated in the notes to
such financial statements and (in the

<PAGE>   4

case of unaudited statements) as permitted by Form 10-Q of the SEC, and except
that unaudited financial statements may not contain footnotes and are subject
to normal and recurring year-end audit adjustments (which will not,
individually or in the aggregate, be IMSI [and its subsidiaries] as of the
respective dates thereof and the consolidated results of operations of IMSI
[and its subsidiaries] for the periods covered thereby.

      5.    Indemnification.

      a.    IMSI agrees to indemnify and hold harmless SPATIAL TECHNOLOGY, its
partners, officers, directors, employees and agents (the "Indemnities") against
any and all losses, liabilities, claims, damages and expenses incurred
(including but not limited to attorneys' fees), to which it may become subject
under the Securities Act, the Securities Act or otherwise, insofar as such
losses, liabilities, claims, damages or expenses (or actions in respect
thereof) arise solely out of any untrue statement of a material fact contained
in the Registration Statement, as originally filed or any amendment thereof, or
the Prospectus, or in any supplement thereto or amendment thereof, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading; provided, however, that IMSI shall not be liable to
SPATIAL TECHNOLOGY for any such losses, liabilities, claims, damages or
expenses which arise out of or are based upon an untrue statement or alleged
untrue statement or omission or alleged omission contained or made in the
Registration Statement or the Prospectus or any amendment thereof or Supplement
thereto in reliance upon and in conformity with information furnished to IMSI
by SPATIAL TECHNOLOGY.

      b.    Promptly after receipt by any Indemnities under subsection a. above
of notice of the commencement of any action, such Indemnities shall, if a claim
in respect thereof is to be made against IMSI under such subsection, notify IMSI
in writing of the commencement thereof. In case any such action is brought
against any Indemnities, and it notifies IMSI of the commencement thereof, IMSI
will be entitled to participate therein and, to the extent it may elect by
written notice delivered to the Indemnities promptly after receiving the
aforesaid notice from such Indemnities, to assume the defense thereof.
Notwithstanding the foregoing, the Indemnities shall have the right to employ
its own counsel in any such case, but the fees and expenses of such counsel
shall be at the expense of such Indemnities unless (i) the employment of such
counsel shall have been authorized in writing by IMSI in connection with the
defense of such action, (ii) IMSI shall not have employed counsel to have charge
of the defense of such action within a reasonable time after notice of
commencement of the action, or (iii) such Indemnities shall have reasonably
concluded that there may be defenses available to it or them which are different
from or additional to those available to IMSI (in which case IMSI shall not have
the right to direct the defense of such action on behalf of the Indemnities), in
any of which events such fees and expenses shall be borne by IMSI. Anything in
this paragraph to the contrary notwithstanding, the indemnifying party shall not
be liable for any settlement of any claim or action effected without its written
consent:

<PAGE>   5
provided, however, that such consent was not unreasonably withheld. IMSI shall
not, without the written consent of the Indemnitee, effect the settlement or
consent to the entry of any judgment in respect of which indemnification may be
sought hereunder unless such settlement or judgment includes an unconditional
release of the Indemnitee from all liability arising out of such action and does
include a statement as to admission of fault.

     6.     Entire Agreement. This Agreement and the retainer (to the extent not
inconsistent herewith) constitute the entire agreement between the parties
hereto with respect to the subject matter hereof and supersede all prior written
agreements and negotiations and oral understandings, if any, with respect
thereto. This Agreement may not be amended or supplemented except by an
instrument in writing signed by each of the parties hereto.

                                  FEE AGREEMENT

        This FEE AGREEMENT (the "Agreement") dated as of March 26,1999, by and
between International Microcomputer Software, Inc. a California corporation
("IMSI"), and StarBase Corporation, a Delaware corporation ("STARBASE").

        WHEREAS, IMSI currently owes STARBASE an amount equal to $121,231 (the
"Fees") pursuant to a License Agreement and Invoices, dated October 22, 1998,
between IMSI and STARBASE (the "License Agreement"), and

        WHEREAS, IMSI and STARBASE now desire to set forth certain terms and
provisions with respect to the payment by IMSI of the Fees:

        NOW, THEREFORE in consideration of the foregoing and for other good and
valuable consideration (the receipt and sufficiency of which are hereby
acknowledged), the parties hereto hereby agree as follows:

        1. Payment of the Fees. Notwithstanding anything to the contrary in the
License Agreement with respect to the form and timing of payment of the Fees,
the obligation to pay the Fees shall be satisfied in full upon compliance by
IMSI with the terms and provisions of this Agreement.

        2. Issuance of the Shares. As soon as reasonably practicable after
execution of this Agreement, IMSI will issue to STARBASE ten thousand seven
hundred fifty (10,750) shares of IMSI's Common Stock (the "Common Stock"), no
par value (collectively, the "Shares").

        3. Sale.

        a. Sale. The Shares may be sold by one or more of the following means of
distribution (subject to the provisions of this Agreement): (a) a block trade in
which the broker-dealer so engaged will attempt to sell Shares as agent, but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a broker-dealer as principal and resale by such
broker-dealer for its own account; (c) an over-the-counter distribution in
accordance with the rules of Nasdaq; (d) ordinary brokerage transactions and
transactions in which the broker solicits purchasers; and (e) in privately
negotiated transactions.

        4. Representations, Warranties and Covenants of IMSI. IMSI represents
and warrants to and covenants with STARBASE as follows:

                a. Registration. IMSI shall use its reasonable best efforts to
cause the shares of IMSI Common Stock that are issuable pursuant to this
Agreement to be registered on a registration statement (or to be issued pursuant
to a then-effective registration statement) on Form S-3 (or successor form)
promulgated by the Securities


<PAGE>   2

and Exchange Commission (the "Commission") under the 1933 Act, as soon as
reasonably practicable after the execution of this Agreement. IMSI shall file
the Form S-3 no later than April 15, 1999. In addition, STARBASE acquires piggy
back registration rights. Nothing herein shall require IMSI to separately
register the Shares.

                b. At the date the Registration Statement becomes effective (the
"Effective Date") under the Securities Act of 1933, as amended (the "Securities
Act") or the time of effectiveness of any post-effective amendment to the
Registration Statement, at the time the Prospectus is first filed with the
Commission pursuant to Rule 424 (b) of the Regulations (if a Rule 424 (b) filing
is required) promulgated under the Securities Act (the "Regulations"), at the
time any supplement to or amendment of the Prospectus is filed with the
Commission and at the time any document filed under the License Act is filed,
the Registration Statement and the Prospectus and any amendments thereof and
supplements thereto complied or will comply in all material respects with the
applicable provisions of the Securities Act and the Regulations or the License
Act and the respective rules and regulations thereunder and do not or will not
contain an untrue statement of a material fact and do not or will not omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein (i) in the case of the Registration Statement, not
misleading and (ii) in the case of the Prospectus, in the light of the
circumstances under which they were made, not misleading.

                c. The Shares, when issued and delivered in accordance with this
Agreement, will be duly and validly issued and outstanding, fully paid and
non-assessable, will not have been issued in violation of any preemptive rights
and will be free and clear of any pledge, mortgage, security interest, lien or
other encumbrance of any nature whatsoever, but will bear restrictive legend
regarding the unregistered nature of the shares until such shares are
effectively registered.

                d. If at any time when a prospectus relating to the Shares is
required to be delivered under the Securities Act any event shall occur as a
result of which the Prospectus as then amended or supplemented, in the judgment
of IMSI or STARBASE, includes an untrue statement of a material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it shall be necessary at any time to amend or
supplement the Prospectus or Registration Statement to comply with the
Securities Act or the Regulations, or to file under the License Act so as to
comply therewith any document incorporated by reference in the Registration
Statement or the Prospectus or in any amendment thereof or supplement thereto,
(i) IMSI will notify STARBASE promptly and prepare and file with the Commission
an appropriate amendment or supplement (in form and substance satisfactory to
STARBASE) which will correct such statement or omission or which will effect
such compliance and will use its best efforts to have any amendment to the
Registration Statement docked declared effective by the Commission as soon as
possible and (ii) STARBASE shall suspend trading in the Shares until (A) such
amendment or supplement to the Prospectus has been


<PAGE>   3

filed or (B) any amendment to the Registration Statement has been declared
effective by the Commission.

                e. IMSI will pay all fees and expenses with respect to the
preparation and filing of the Registration Statement and the registration of the
Shares. If however, STARBASE requests that the Shares be registered
independently from another IMSI registration ("Accelerated Registration), then
STARBASE shall pay all fees and expenses with respect to the preparation and
filing of the Registration Statement and the registration of the Shares that are
a result of such Accelerated Registration.

                f. So long as the Form S-3 is effective within 180 days of
filing, STARBASE releases and forever discharges payment of the Fees pursuant to
the terms and conditions of the License Agreement.

        5. Indemnification.

a. IMSI agrees to indemnify and hold harmless STARBASE, against any and all
losses, liabilities, claims, damages and expenses incurred (including but not
limited to attorneys' fees), to which it may become subject under the Securities
Act, the License Act or otherwise, insofar as such losses, liabilities, claims,
damages or expenses (or actions in respect thereof) arise solely out of any
untrue statement of a material fact contained in the Registration Statement, as
originally filed or any amendment thereof, or the Prospectus, or in any
supplement thereto or amendment thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading;
provided, however, that IMSI shall not be liable to STARBASE for any such
losses, liabilities, claims, damages or expenses which arise out of or are based
upon an untrue statement or alleged untrue statement or omission or alleged
omission contained or made in the Registration Statement or the Prospectus or
any amendment thereof or Supplement thereto in reliance upon and in conformity
with information furnished to IMSI by STARBASE.

                b. Promptly after receipt by any indemnified party under
subsection a. above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the party against whom
indemnification is to be sought in writing of the commencement thereof. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof.
Notwithstanding the foregoing, the indemnified party or parties shall have the
right to employ its own counsel in any such case, but the fees and expenses of
such counsel shall be at the expense of such indemnified party unless (i) the
employment of such counsel shall have been authorized in writing by the
indemnifying party in connection with the defense of such


<PAGE>   4

action, (ii) the indemnifying party shall not have employed counsel to have
charge of the defense of such action within a reasonable time after notice of
commencement of the action, or (iii) such indemnified party shall have
reasonably concluded that there may be defenses available to it or them which
are different from or additional to those available to the indemnifying party
(in which case the indemnifying party shall not have the right to direct the
defense of such action on behalf of the indemnified party or parties), in any of
which events such fees and expenses shall be borne by the indemnifying party.
Anything in this subsection to the contrary notwithstanding, the indemnifying
party shall not be liable for any settlement of any claim or action effected
without its written consent;provided, however, that such consent was not
unreasonably withheld.

        6. Entire Agreement. This Agreement and the License Agreement (to the
extent not inconsistent herewith) constitute the entire agreement between the
parties hereto with respect to the subject matter hereof and supersede all prior
written agreements and negotiations and oral understandings, if any, with
respect thereto. This Agreement may not be amended or supplemented except by an
instrument in writing signed by each of the parties hereto.

wire transfer to an account designated in writing by the Zedcor Shareholders to
IMSI.

         2. Amendment of "Shares" in Fee Agreement. The term "Shares" as defined
in Section 2 of the Fee Agreement is hereby amended to be 187,901 shares of
Common Stock, which equals the Fees divided by $8.00; and after the date of this
Agreement, the term "Shares" shall refer to such 187,901 shares.

         3. Issuance of Additional Shares. In consideration of the agreements of
Zedcor and the Zedcor Shareholders hereunder, within five business days after
the date that this Agreement is executed and delivered by all parties hereto,
IMSI shall issue to Zedcor 10,000 shares (the "Additional Shares") of Common
Stock. Such shares shall be included in the Registration Statement (as described
below).

         4. The Registration Statement.

                  4.1 Filing of the Registration Statement. IMSI will use its
best efforts to file a registration statement on Form S-3 (or other appropriate
form) (the "Registration Statement") on or before September 30, 1999, with the
Securities and Exchange Commission (the "SEC") registering the resale of the
Shares and the Additional Shares. The Registration Statement may also include
shares issued or issuable to other security holders of IMSI.

                  4.2 Consequences for Late Filing. If the Registration
Statement is not filed with the SEC by September 30, 1999, then upon notice from
the Zedcor Shareholders, IMSI shall redeem 12,500 Shares from the Zedcor
Shareholders (in proportion to their relative ownership of the Shares) each
month until the Registration Statement is filed. The purchase price for such
redeemed shares shall be $8.00 per share. The maximum dollar amount that IMSI
shall be required to pay to redeem Shares under this section (the "Maximum
Redemption Amount") shall be an amount equal to the amount of the Fees (minus
the dollar amount of previous redemptions of Shares from time to time), plus
interest on such amount at an annual rate of 8% per annum until such time as the
Shares may be sold pursuant to SEC Rule 144 (subject to the volume and other
provisions of that rule). IMSI shall have no further obligation to redeem Shares
at such time as the Shares may be sold pursuant to the provisions of SEC Rule
144 (subject to the volume and other provisions of that rule). The initial
redemption shall occur within

                                       2

<PAGE>   3


10 business days after delivery of the redemption notice from the Zedcor
Shareholders, and thereafter the redemption (and delivery of the redemption
price) shall occur on each monthly anniversary of the initial redemption date,
until the Registration Statement is filed or until the Maximum Redemption Amount
has been paid. The Zedcor Shareholders shall execute such instruments (including
without limitation delivery of stock certificates representing the Shares to be
redeemed and duly executed stock assignments) as IMSI may reasonably request in
connection with any such redemption.

                  4.3 Potential Issuance of Additional Shares. If, on the date
which is three business days before the date the Registration Statement is
declared effective by the SEC (the "Measurement Date"), the Average Market Price
is less than $8.00 per share, then IMSI shall issue, within three business days
of the Measurement Date, a number of additional shares of Common Stock (which
shall be deemed to be "Shares") to the Zedcor Shareholders (in proportion to
their relative ownership of Shares), such that the total number of "Shares"
(taking into account the 187,901 Shares described in Section 2 above) equals
$1,503,207.10 divided by the Average Market Price. The "Average Market Price"
shall mean the average of the closing sales prices of the Common Stock (as
quoted on Nasdaq) for the ten trading days before the Measurement Date;
provided, however, that the Average Market Price shall in no event be deemed to
be less than $4.00.

         5. Release of Security Interest. Each of the Representative and each
Zedcor Shareholder hereby releases any and all security interests or similar
rights that such person may have in and to the Collateral (as defined in the
Transaction Documents) and hereby releases IMSI from any and all obligations and
liabilities that IMSI otherwise may have in connection with the Collateral. Each
of the Representative and each Zedcor Shareholder acknowledges that no event of
default has occurred with respect to the Collateral under the Transaction
Documents, and that after the date of this Agreement, IMSI may grant and create
a first priority security interest in the Collateral in favor of another person
or entity without any conflict with any right of the Representative or the
Zedcor Shareholders. Each of the Representative and each Zedcor Shareholder
agrees to take such actions and execute such instruments as IMSI may reasonably
request in order to confirm the termination of the security interest and any
similar rights.

         6. Release of Claims. Each of Zedcor, the Representative and each
Zedcor Shareholder (individually a "Releasing Party" and collectively, the
"Releasing Parties") hereby releases IMSI and its subsidiaries, successors and
assigns, directors, officers, employees, attorneys and agents (collectively, the
"Released Parties") from and against any and all claims, causes of action,
complaints, charges, demands, liabilities, damages, losses, costs or expenses of
any kind whatsoever (including attorney's fees and costs), arising out of or
relating to any delay by IMSI before the date of this Agreement in filing the
registration statement contemplated by the Transaction Agreements.

         7. No Other Changes. Except as set forth in this Agreement, all other
terms and conditions of the Transaction Agreements shall remain in full force
and effect. In the



                                       3

event of any conflict between the terms of this Agreement and the terms of any
Transaction Agreement, the terms of this Agreement shall control, and the
Transaction Agreements shall be interpreted so as to be consistent with the
provisions of this Agreement.

         8. Miscellaneous.

                  8.1 Governing Law; Consent to Jurisdiction. The validity,
construction and performance of this Note will be governed by the laws of the

be made in the manner provided for in this Agreement for delivery of notices.

each case addressed to the other party at such party's address (or facsimile
number, in the case of transmission by telecopier) as shown in the Exchange
Agreement, or to such other address as such party may designate in writing from
time to time to the other party.

                  8.3 Amendments and Waivers. No amendment or modification of
this Agreement may be made or be effective unless and until it is set forth in
writing and signed by IMSI and the Representative. Any such amendment or
modification shall be binding on all Zedcor Shareholders. No waiver of any right
under this Agreement will be effective unless expressly set forth in a writing
signed by IMSI and/or the Representative, as applicable.

                  8.4 Successor and Assigns. The provisions of this Agreement

                                                                    June 7, 1999

Gentlemen/Ladies:

     I have examined the Registration Statement on Form S-3 (the "Registration
Statement") to be filed by you with the Securities and Exchange Commission (the
"Commission") on or about June 7, 1999, in connection with the registration
under the Securities Act of 1933, as amended, of an aggregate of 2,534,823
shares of your Common Stock (the "Stock"), all of which will be sold by the
selling shareholders named in the Prospectus included within the Registration
Statement (the "Selling Shareholders").

     In rendering this opinion, I have examined the following:

     (1)  the Registration statement, together with the Exhibits filed as a
part thereof;

     (2)  the Prospectus prepared in connection with the Registration Statement;

     (3)  the minutes of meetings and actions by written consent of the Board
of Directors that are contained in your minute books and that are in our
possession, that relate to the issuance of the Stock and the Warrant;

     (4)  the stock purchase and other agreements, other than those filed as
exhibits to the Registration Statement, pursuant to which the Selling
Shareholders acquired the Stock and the Warrant as described in the
Registration Statement; and

     (5)  such other documents as I have deemed appropriate in order to provide
this opinion.

     In my examination of documents for purposes of this opinion, I have
assumed, and express no opinion as to, the genuineness of all signatures on
original documents, the authenticity of all documents submitted to me as
originals, the conformity to originals of all documents submitted to me as
copies, the legal capacity of all natural persons executing the same, the lack
of any undisclosed terminations, modifications, waivers or amendments to any
documents reviewed by me and the due execution and delivery of all documents
where due execution and delivery are prerequisites to the effectiveness
thereof.

     As to matters of fact relevant to this opinion, I have relied solely upon
my examination of the documents referred to above and have assumed the current
accuracy and completeness of the information obtained from records included in
the documents referred to above. I have made no independent investigation or
other attempt to verify the accuracy of any of such information or to determine
the existence or non-existence of any other factual matters; however, I am not
aware of any facts that would lead me to believe that the opinion expressed
herein is not accurate.

<PAGE>   2
     In rendering any opinion that the shares of Stock are, or will when issued
be, "fully paid," I have assumed that such shares will be issued in accordance
with the terms of the underwriting agreement filed as an exhibit to the
Registration Statement, and that the Company will receive full consideration
for the issuance of such shares provided for in such agreement.

     Based upon the foregoing, it is my opinion that the shares of Stock to be
issued by the Company pursuant to the Registration Statement are legally issued
and nonassessable and, to our knowledge, fully paid.

     I consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to all references to me, if any, in the
Registration Statement, the Prospectus constituting a part thereof and any
amendments thereto.

     This opinion speaks only as of its date and is intended solely for the
your use as an exhibit to the Registration Statement for the purpose of the
above sale of the Stock and is not to be relied upon for any other purpose.



                         Very truly yours,


                         /s/ GEOFFREY B. KOBLICK, ESQ.
                         ------------------------------
