This Prospectus and the information contained herein are subject to completion
or amendment. These securities may not be sold nor may offers to buy be
accepted, prior to the time the prospectus is delivered in final form. Under no
circumstances shall this Preliminary Prospectus constitute an offer to sell or
the solicitation of an offer to buy nor shall there be any sale of these
securities in any jurisdiction in which such offer, solicitation or sale would
be unlawful prior to registration or qualification under the securities laws of
any such jurisdiction.

                 SUBJECT TO COMPLETION, DATED DECEMBER 22, 1997

                                  20,000 SHARES

                   INTERNATIONAL MICROCOMPUTER SOFTWARE, INC.

                                  COMMON STOCK

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

        All of the shares of Common Stock offered hereby ("the "Shares") are
being offered by the shareholders named herein under "Selling Shareholders"
(such shareholders are sometimes referred to herein as the "Shareholders"). Such
shares are being offered on a continuous basis pursuant to Rule 415 under the
Securities Act of 1933, as amended. No underwriting discounts, commissions or
expenses are payable or applicable in connection with the sale of such shares.
The Common Stock of International Microcomputer Software, Inc. (the "Company")
is quoted on the Nasdaq National Market under the symbol "IMSI." The shares of
Common Stock offered hereby will be sold from time to time at then prevailing
market prices, at prices relating to prevailing market prices or at negotiated
prices. On December 22, 1997 the closing price of the Common Stock on the Nasdaq
National Market was $13.25 per share.

        The Shares offered hereby were issued by the Company in connection with
its acquisition of MediaPaq, Inc. ("MediaPaq") on August 22, 1997.

        The Shareholders represented to the Company, in the agreements relating
to their acquisition of the Shares covered hereby, that they were acquiring such
Shares for investment and with no present intention of distributing or reselling
such Shares. However, in recognition of the fact that each such Shareholder,
even though purchasing such shares for investment, may wish to be legally
permitted to sell the Shares when they deem appropriate, the Company has filed
with the Securities and Exchange Commission (the "Commission") a registration
statement of which this Prospectus forms a part with respect to the sale of such
Shares from time to time. See "Selling Shareholders." To the Company's
knowledge, as of the date of this Prospectus no Shareholder has entered into any
agreement, arrangement or understanding with any particular broker, market maker
or other person with respect to sale of any of the Shares offered hereby.

        The Shares are being offered on a continuous basis pursuant to Rule 415
under the Securities Act of 1933, as amended (the "Securities Act"). The Company
will pay the expenses of registration estimated at $16,000. No underwriting
discounts, commissions or expenses are payable or applicable in connection with
the sale of the Shares. The Shares offered hereby may be sold from time to time
at then prevailing market prices, at prices relating to prevailing market prices
or at negotiated prices. This Prospectus may be used by the Shareholders or by
any broker-dealer who may participate in sales of the Common Stock covered
hereby. In addition, any Shares offered hereby which qualify for sale pursuant
to Rule 144 under the Securities Act or any other exemption may be sold under
Rule 144 or another exemption rather than pursuant to this Prospectus.

              SEE "RISK FACTORS" COMMENCING ON PAGE 4 HEREOF FOR A
      DISCUSSION OF CERTAIN FACTORS THAT SHOULD BE CONSIDERED IN CONNECTION
             WITH AN INVESTMENT IN THE COMMON STOCK OFFERED HEREBY.

    THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
       AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS
         THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
             COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
                PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS
                               A CRIMINAL OFFENSE.

                                  RISK FACTORS

        Investors should consider carefully the following risk factors, in
addition to the other information contained in this Prospectus, before
purchasing the shares of Common Stock offered hereby.

        This Prospectus contains forward-looking statements which involve risks
and uncertainties. Discussions containing such forward-looking statements may be
found in the materials set forth under "Risk Factors," as well as in the
documents incorporated by reference herein and other documents filed by the
Company under the Exchange Act. Actual events or results may differ materially
from those discussed in this Prospectus. Given these uncertainties, Prospectus
investors are cautioned not to place undue reliance on such forward-looking
statements. The Company disclaims any obligation to update such factors or to
publicly announce the results of any revisions to any of the forward-looking
statements contained herein to reflect any events or developments.

        Important factors and assumptions that could cause the Company's actual
results to differ materially from those included in the forward-looking
statements made herein include the factors that are responsible for
period-to-period fluctuations in the Company's operating results generally.
These factors include without limitation the integration of operations resulting
from acquisitions of companies or products, delays in customer purchases in
anticipation of upgrades to existing products or release of competitive
products, currency fluctuations, dealer and distributor order patterns and
seasonality of buying patterns of customers and the historic and recurring
pattern of Company sales by which a disproportionate percentage of a quarter's
total sales occur in the last month and weeks of each quarter, making
predictions of revenues and earnings especially difficult and resulting in
substantial risk of variance of actual results from those existing at any time
prior to near the end of the quarter. Additional factors and assumptions that
could generally cause the Company's actual results to differ materially from
those included in the forward-looking statements made herein include without
limitation the Company's ability to develop and introduce new products or new
versions of existing products, the effects of general economic conditions, the
impact of competitive products and pricing in the consumer software industry,
the Company's ability to keep pace with the evolution of the technology
platforms for which the Company develops and produces products and the Company's
ability to continue to exploit new channels of distribution for its products.

        FLUCTUATIONS IN OPERATING RESULTS. The Company has experienced and may
in the future experience significant quarterly and annual fluctuations in
revenues and results of operations. Although the Company experienced growth
during fiscal years 1997 and 1996, the Company experienced a net loss for fiscal
1995, and for the Company's first quarter ended September 30, 1997, the Company
reported a net loss of approximately $3.1 million, reflecting in part charges,
accounted for primarily as in-process research and development, amounting to
approximately $6.4 million relating to several product acquisition and licensing
transactions. The Company's revenues and results of operations fluctuate as a
result of a variety of factors, including but not limited to the level of
software sales, the degree of acceptance of the Company's products, the amount
of revenue generated from products which require third party royalty payments,
changes in product mix, competitive conditions in the industry, general economic
conditions and the effects of the Company's acquisitions of products and
technologies from third parties. Furthermore, the growth in revenue rates that
the Company experienced during fiscal 1997 may not continue into fiscal 1998 and
beyond. Shortfalls in revenues or earnings from levels expected by the financial
market could have an immediate and significant adverse effect on the trading
price of the Common Stock. Future operating results will continue to depend
heavily on the level of software sales.

        Due to the acceptance and demand associated with the Company's software
products, revenues are difficult to forecast and may fluctuate dramatically
between reporting periods. Future prices the Company will be able to obtain for
its software products may decrease from historical levels depending on, among
other things, competitive factors. There can be no assurances that the Company
will continue the software revenue growth trend experienced in fiscal 1997 or
that the Company will achieve historical levels of software revenue.




                                       4
<PAGE>   6

        The Company plans to increase its presence in international markets.
Risks associated with such pursuits include, but are not limited to, the
following: changing market demands, economic and political conditions in foreign
markets, foreign exchange fluctuations, longer collections cycles and changes in
international tax laws. During fiscal 1997, the Company experienced an increase
in revenues in all international subsidiaries. There can be no assurances that
revenues from the Company's international subsidiaries will continue to
increase.

        The Company generates revenue from internally developed software
products, some of which utilize technology licensed from third parties. The
Company expects to continue utilizing third party technology and may enter into
agreements with additional business partners. If sales of software 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 can be no assurances that the third parties will renew or not
cancel existing agreements with the Company or require financial conditions
which are unfavorable to the Company.

        The Company expects product development expenses to grow in future
periods to fund development efforts on new and existing products. However, there
can be no assurances that revenues will be sufficient to support the future
product development which is required for the Company to be competitive.
Although the Company may be able to release new products in addition to
enhancements to existing products, there can be no assurances that the Company's
new or upgraded products will be accepted, will not be delayed or canceled, or
will not contain errors or "bugs" that could affect the performance of the
product or cause damage to users' data.

        The Company expects sales and marketing expenses to increase in the
future as the Company releases and promotes new products, increases promotions
of existing product lines and continues to build its sales force. However,
because of the lengthy sales cycle associated with software applications, the
Company believes that the impact of these activities, if any, on future license
revenues will not be immediate and there can be no assurances that increased
sales, business and consumer, and marketing expenditures will result in
increased revenues.

        COMPETITION. The business and consumer software market is intensely
competitive and rapidly changing. A number of competitors offer products similar
to the Company's products and target the same customers. The Company believes
that its ability to compete depends upon many factors, some of which are within
its control and some of which are not, including the timing and market
acceptance of new products and enhancements developed by the Company and its
competitors, product functionality, performance, price, reliability, customer
service and support, sales and marketing efforts and product distribution. The
Company has many competitors including Visio Corporation, Learning Company,
Inc., Autodesk, Inc., Corel Corporation, Broderbund Software, Inc., and Expert
Software, Inc. The Company's products also compete with products offered by
other vendors, with systems integrators and with consulting companies that offer
custom software development services. In addition, the Company competes with
in-house management information services and programming resources of its
potential customers. Many of the Company's competitors have substantially
greater financial, technical marketing and sales resources than the Company.
Some of these competitors also offer business application products not offered
by the Company. There can be no assurances that the Company will be able to
compete successfully in the future.

        RAPID TECHNOLOGICAL CHANGE. The software industry is characterized by
rapid technological change. The pace of change has accelerated due to advances
in mainframe and client/server technology and the growth in internet, intranet
and extranet utilization. The Company expects to evaluate potential
opportunities and may invest in those which are compatible with the Company's
strategic direction. However, there can be no assurances that any such
investments will be profitable. The introduction of products embodying new
technologies and the emergence of new industry standards can render existing
products obsolete. Accordingly, the Company's future success will depend in part
upon its ability to continue to enhance its current products and to develop and
introduce new products that respond to evolving customer requirements and keep
pace with technological development and emerging industry standards, such as new
operating systems, hardware platforms, interfaces and third party applications
software. There can be no assurances that the Company will be successful in
developing and marketing product enhancements or new products that respond to
technological change, changes in customer requirements or emerging industry
standards, that the Company will not experience difficulties that could delay or
prevent the successful development, introduction and marketing of such products
and enhancements, or that any new products or enhancements that it may introduce
will achieve market acceptance.

        RECENT ACQUISITION TRANSACTIONS. The Company has in the past acquired
many products and technologies from third parties in order to broaden its
product lines and geographic sales channels. During the fiscal year ended June
30, 1997 and the first quarter of fiscal 1998, the Company acquired a number of
products and technologies. For example, during the first quarter of fiscal 1998,
the Company 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 Corporation exclusive worldwide licensing rights to the Hijaak
graphics utility products; acquired certain assets of MediaPaq, Inc., including
its browser technology; and acquired certain assets of MapLinx, Inc., including
a mapping software program.

        The Company's product and technology acquisitions and additions have
expanded the Company's size and number of product lines, and have resulted in an
increase in the number of employees. There are significant risks associated with
this growth. Certain of the Company's acquisitions have involved issuances of
equity securities and resulted in various charges and expenses which have
adversely affected, and will continue to affect, the Company's operating results
and financial condition. The Company's ability to integrate and organize its new
products and to successfully predict and manage its growth will require
improvements in its operational, financial and management information systems.
Acquiring products also creates the risk that the Company will not be able to
complete any development of acquired products that may be required on a timely
basis or at all, integrate the acquired products into the Company's product
lines, successfully integrate employees who may join the Company in connection
with such transaction, or successfully market the acquired products. There can
be no assurances that such problems will not have a material adverse effect on
the Company's results of operations. Moreover, there can be no assurance that
the anticipated benefits of any specific acquisition will be realized or that
the Company will not encounter difficulties in integrating these or future
businesses, products or technologies.

        PRODUCT CONCENTRATION. The Company's results of operations depend to a
significant extent on revenues of the Computer-Aided Product Line and Desktop
Publishing Line. Revenues from sales of the Company's Computer-Aided Design
Product Line and Desktop Publishing Line were approximately 65% of the Company's
total revenues for the fiscal year 1996 and 77% for the fiscal year 1997.
Although the Company publishes a broad range of products, the Company believes
that its revenues and results of operations will continue to depend for the
foreseeable future on the success of these product lines. Accordingly, the
Company's future results of operations will depend, in part, on continued and
expanded market acceptance of these product lines, as well as the Company's
ability to continue to enhance these product lines and to introduce new
products. A reduction in demand, or an increase in competition in the markets
for these product lines, or a decline in sales of these product lines, could
have a material adverse effect on the Company's business, financial condition
and results of operation.

        PROPRIETARY RIGHTS. The Company regards its products as proprietary.
Through its license agreements with customers and its internal security systems,
confidentiality procedures and employee agreements, the Company has taken steps
to protect its trade secrets and other intellectual property relating to its
products. However, there can be no assurances that misappropriation will not
occur. In addition, the laws of some countries do not protect the Company's
proprietary rights to the same extent as do the laws of the United States.

        The Company is not aware of any claims that its products infringe on the
proprietary rights of third parties, however, there can be no assurances that
third parties will not assert infringement claims against the Company in the
future with respect to current or future products, and any such claims could
require the Company to enter into royalty arrangements or result in costly
litigation.

        EMPLOYEES. The Company's success depends on a number of its key
employees. The loss of the services of the Company's key employees could have a
material adverse effect on the Company. The Company believes that its future
success will also depend in large part on its ability to attract and retain
highly-skilled technical and management personnel. Competition for such
personnel in the software industry is intense and the supply is limited. There
can be no assurances that the Company will be successful in attracting and
retaining such personnel.

        QUARTERLY TRENDS. The Company's consolidated results of operations to
date have not been materially affected by seasonal trends. However, the Company
believes that in the future its results may be impacted by such factors as order
deferrals in anticipation of new product releases, delays in shipments of new
products, a slower growth rate in the software markets in which the Company
operates, or adverse general economic and industry conditions in any of the
countries in which the Company does business. In addition, with significant
portions of net revenues contributed by international operations, fluctuations
of the U.S. dollar against foreign currencies and the seasonality of the
European, Asia/Pacific, and other international markets could impact the
Company's results of operations and financial position in a particular quarter.
Rapid technological change and the Company's ability to develop, manufacture,
and market products that successfully adapt to the change may also impact
results of operations. Further, increased market competition from current or
future competitors could also negatively impact the Company's results of
operations. Due to these factors, the Company's future earnings and stock price
may by subject to significant volatility, particularly on a quarterly basis. Any
shortfall in revenues or earnings from anticipated levels could have an
immediate and adverse effect on the trading price of the Common Stock.

                                  SHAREHOLDERS

        Each Shareholder acquired the shares of Common Stock offered by such
Shareholder hereby in connection with the Company's acquisition of MediaPaq,
pursuant to an Exchange Agreement dated August 22, 1997 (the "Exchange
Agreement"). In the Exchange Agreement, each Shareholder exchanged their
MediaPaq equity securities for Common Stock of the Company. In the Exchange
Agreement, each of the Shareholders represented to the Company that it was
acquiring the Shares covered hereby for investment and with no present intention
of distributing or reselling such Shares. However, in recognition of the fact
that each such Shareholder, even though acquiring such Shares for investment may
wish to be legally permitted to sell the Shares when it deems appropriate. The
Company has filed with the Commission the Registration Statement with respect to
the sale of such Shares from time to time. No Shareholder has had any position,
office or other material relationship with the Company within the past three
years. One or more of the Shareholders may from time to time provide consulting
services to the Company and receive compensation from the Company for such
services, but as of the date of this Prospectus the Company has not entered into
any agreements with any Shareholder with respect to any such services.

        The following table sets forth certain information known to the Company
with respect to the beneficial ownership of the Company's Common Stock as of

                              PLAN OF DISTRIBUTION

        The Registration Statement of which this Prospectus forms a part has
been filed pursuant to registration rights granted to the Shareholders pursuant
to the Exchange Agreement. To the Company's knowledge, no Shareholder has
entered into any agreement, arrangement or understanding with any particular
broker or market maker with respect to the Shares offered hereby, nor does the
Company know the identity of the brokers or market makers that will participate
in the offering.

        The Shareholders' Shares covered hereby may be offered and sold from
time to time by the Shareholders at then prevailing market prices, at prices
relating to prevailing market prices or at negotiated prices. In addition, any
Shares offered hereby which qualify for sale pursuant to Rule 144 under the
Securities Act or any other exemption may be sold under Rule 144 or another
exemption rather than pursuant to the Prospectus. The Shareholders will act
independently of the Company in making decisions with respect to the timing,
manner and size of each sale. No assurances can be given that the Shareholders
will sell any of the Shares that are subject to this Prospectus or that any
Shareholder will not sell such Shares in a private transaction or other
transaction that is exempt from the registration requirements of the Securities
Act. The Company has been advised by the Shareholders that they have not, as of
the date hereof, entered into any arrangement with a broker-dealer for the sale
of shares. In effecting sales, broker-dealers engaged by the Shareholders may
arrange for other broker-dealers to participate. Broker-dealers will receive
commissions or discounts from the Shareholders in amounts to be negotiated prior
to the sale.




                                       8
<PAGE>   10

        The Shares may be sold by one or more of the following methods: (a) a
block trade in which the broker-dealer engaged by the Shareholder will attempt
to sell the shares as agent but may position and resell a portion of the block
as principal to facilitate the transaction; (b) through privately negotiated
transactions; (c) purchases by the broker-dealer as principal and resale by such
broker or dealer for its account pursuant to this Prospectus; and (d) ordinary
brokerage transactions and transactions in which the broker solicits purchasers.
To the Company's knowledge, the Shareholders have not, as of the date hereof,
entered into any arrangement with a broker-dealer for the sale of shares through
a block trade, special offering, or secondary distribution of a purchase by a
broker-dealer. In effecting sales, broker-dealers engaged by the Shareholders
may arrange for other broker-dealers to participate. Broker-dealers will receive
commissions or discounts from the Shareholders in amounts to be negotiated.

        In offering the Shares, the Shareholders and any broker-dealers who
execute sales for the Shareholders may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales, and any profits
realized by the Shareholders and the compensation of such broker-dealer may be
deemed to be underwriting discounts and commissions.

        The Shareholders have advised the Company that, during such time as they
may be engaged in a distribution of the shares of Common Stock included herein,
they will comply with Regulation M promulgated under the Exchange Act and, in
connection therewith, the Shareholders have agreed not to engage in any
stabilization activity in connection with any securities of the Company, to
furnish copies of this Prospectus to each broker-dealer through which the shares
of Common Stock included herein may be offered, and not to bid for or purchase
any securities of the Company or attempt to induce any person to purchase any
securities of the Company except as permitted under the Exchange Act. The
Shareholders have also agreed to inform the Company and broker-dealers through
whom sales may be made hereunder when the distribution of the shares is
completed.

        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.

        This Offering will terminate as to each Shareholder on the earlier of
(a) the date on which such Shareholder's shares may be resold without volume
restrictions under the Securities Act; or (b) the date on which all Shares
offered hereby have been sold by the Shareholders. There can be no assurance
that any of the Shareholders will sell any or all of the shares of Common Stock
offered hereby.

                                  LEGAL MATTERS

        The validity of the issuance of the shares of Common Stock offered
hereby will be passed upon for the Company by Geoffrey B. Koblick, in-house
counsel to the Company. Mr. Koblick is chairman of the Company and beneficially
owns 503,696 shares of Common Stock.

</TABLE>


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 the Company'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.




                                      II-1
<PAGE>   13

               (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 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
shareholders 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.

        The Company has not purchased directors' and officers' liability
insurance which would indemnify the directors and officers of the Company
against damages arising out of certain kinds of claims which might be made
against them based on their negligent acts or omissions while acting in their
capacity as such.

ITEM 17.       UNDERTAKINGS.

        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:




                                      II-2
<PAGE>   14

               (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.

        2. THE EXCHANGE

           Subject to the terms and conditions of this Agreement, at the
Closing:

           (a) each of the MP Shareholders shall irrevocably assign and transfer
to IMSI all of their shares of MP Stock, the amounts of which are set forth
beside their respective names on Exhibit A, and in exchange therefor IMSI shall
issue to each MP Shareholder the number of shares of IMSI Common Stock
determined in accordance with Section 2.1 below;

           (b) in addition, IMSI shall pay the liabilities of MP in the
aggregate sum of U.S. $160,000.00 directly to DataCal corporation, A. Brent
Payne and Lunt Family Investment Limited Partnership, and

           (c) all MP Options shall expire.

                   2.1 At the Closing, each share of MP 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 MP Shareholder of the
applicable MP 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
MP Shareholder shall receive a stock certificate for its Exchange Shares once
the shares are registered.

                   2.1.2 Fractional Shares. No fractional shares of IMSI Common
Stock shall be issued in connection with the Exchange. MP shall discharge any
and all fractional shares of MP stock prior to the Closing Date.

                   2.1.3 Registration Rights. IMSI agrees to register all the
shares granted to MP Shareholders under this Agreement at no additional charge
to the MP shareholders.

           2.2 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 MP 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 MP Stock are to be exchanged in the Exchange shall be appropriately,
equitably and proportionately adjusted (as agreed to by IMSI and MP 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
MP and the shareholders of IMSI contemplated hereby so as to maintain the
proportional interests of the holders of MP Stock contemplated by this
Agreement. The provisions of this Section shall not apply to any transaction not
permitted to be undertaken by MP 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 




                                       3
<PAGE>   4

have been equitably adjusted to reflect such Capital Change as necessary to
effect the purposes and intent of this Section.

               2.3 Escrow Agreement. At the Closing, IMSI shall withhold ten
percent (10%) of the shares of IMSI Common Stock to be issued to the MP
Shareholders in accordance with Section 2.1, rounded down to the nearest whole
number of shares of IMSI Common Stock to be issued to each MP Shareholder (the
"ESCROW SHARES") and will deliver certificates representing such Escrow Shares
to the West America Bank, or a similar institution, as escrow agent (the "ESCROW
AGENT"), together with related stock transfer powers, to be held by the Escrow
Agent as security for the MP Shareholders' indemnification obligations under
Section 11 and pursuant to the provisions of an Escrow Agreement (the "ESCROW
AGREEMENT") that shall be memorialized in a separate document afther the date of
Closing and before the shares are registered. The Escrow Shares will be
represented by certificates issued in the names of the MP Shareholders in
proportion to their respective interests therein and will be held by the Escrow
Agent during that time period (the "ESCROW PERIOD") specified in the Escrow
Agreement. The MP Shareholders, hereby consent to, approve and agree to be
personally bound by: (i) the indemnification provisions of Section 11 of this
Agreement (the primary MP Shareholders only); (ii) all of the terms, conditions
and limitations in the Escrow Agreement; and (iii) the appointment of James Lunt
as the representative of the MP Shareholders (the "REPRESENTATIVE") under the
Escrow Agreement and as the attorney-in-fact and agent for and on behalf of each
MP Shareholder as provided in the Escrow Agreement, 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 the Escrow
Agreement (including, without limitation, the exercise by the Representative of
the power to: (i) authorize delivery to IMSI of Escrow Shares in satisfaction of
claims by IMSI or any other Indemnified Person (as defined herein); (ii) agree
to, negotiate 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 MP Shareholder with respect to the Escrow Agreement and the
disposition, settlement or other handling of all claims governed by the Escrow
Agreement, and all rights or obligations arising under the Escrow Agreement so
long as all MP Shareholders are treated in the same manner. The MP Shareholders
will be bound by all actions taken by the Representative in connection with the
Escrow Agreement, and IMSI will be entitled to rely on any action or decision of
the Representative. In performing the functions specified in this Agreement and
the Escrow Agreement, the Representative will not be liable to the MP
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 the
terms of the Escrow Agreement will be paid by distribution of shares from the
escrow to the Representative in proportion to each shareholder's respective
percentage interests in the Escrow Shares.

               2.4 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,
MP and their respective officers and directors may, and each MP Shareholder




                                       4
<PAGE>   5

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 MP or otherwise.

               2.5 Securities Laws Issues. IMSI shall issue the Exchange Shares
pursuant to an exemption from registration under Section 4(2) and/or Regulation
D promulgated under the 1933 Act.

               2.6 Pooling of Interests. The parties acknowledge that, as a
material inducement to IMSI to enter into this Agreement and consummate the
Exchange, the Exchange is intended to qualify as a "pooling of interests" for
accounting purposes, provided, however, neither MP nor any MP Shareholder
represent that this transaction so qualifies.

            3. REPRESENTATIONS AND WARRANTIES OF MEDIAPAQ AND THE 
               MEDIAPAQ SHAREHOLDERS

                   3.4.3 Securities. All outstanding shares of stock of the MP
Subsidiaries are validly issued, fully paid and nonassessable and not subject to
preemptive rights and are owned of record and beneficially solely by MP. The
outstanding shares of the MP Subsidiaries are not subject to any claim, lien,

indirectly) any shares of any of the authorized but unissued capital stock of
any of the MP Subsidiaries or any securities convertible into or exchangeable
for any shares of capital stock of any of the MP Subsidiaries or obligating any
of the MP Subsidiaries to grant, issue, extend, or enter into any such option,
warrant, convertible or other security, call, commitment, conversion privilege,
preemptive right or other right or agreement. No person or entity holds or has

               3.5 No Violation of Existing Agreements. Neither the execution
and delivery of this Agreement or any MP Ancillary Agreement, nor the
consummation of the Exchange or any of the other transactions contemplated
hereby, nor MP'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 MP as currently in
effect; (ii) any federal, state, local or foreign judgment, writ, decree, order,
statute, rule or regulation applicable to MP or its assets or properties; or
(iii) any material instrument, agreement, contract, letter of intent or
commitment to which MP is a party or by which MP or its assets or properties are
or were bound. The consummation of the Exchange by MP will not require the
consent of any third party other than the approval of the MP Shareholders and MP
Optionees and no agreement to which MP 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 MP (or against any officer or
director of MP or, to the best of the knowledge of MP and the MP Shareholders,
against any employee or agent of MP, in their capacity as such or relating to
their employment, services or relationship with MP) before any court,
administrative agency or arbitrator that, if determined adversely to MP (or any
such officer, director, employee or agent) may reasonably be expected to have a
Material Adverse Effect on MP, nor, to the best of MP'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 MP or IMSI based upon: (a) MP's entering into this
Agreement or consummating the Exchange; (b) any claims of ownership, rights to
ownership, or options (except for the 11.4 options described in Section 3.3.2
and set forth on Exhibit B hereto), warrants or other rights to acquire
ownership, of any shares of the capital stock of MP; or (c) any rights as a MP




                                       7
<PAGE>   8

shareholder, including any option, warrant or preemptive rights or rights to
notice or to vote. There is no judgment, decree, injunction, rule or order of
any governmental entity or agency, court or arbitrator outstanding against MP.

foreign tax returns required to be filed, has timely paid all taxes required to
be paid in respect of all periods for which returns have been filed, has
established an adequate accrual or reserve for the payment of all taxes payable

minimum income, gains, franchise, excise, property, sales, use, employment,
license, payroll (including any taxes or similar payments required to be

governmental charges, fees, customs duties, levies or assessments (whether
payable directly or by withholding), and, with respect to such taxes, any
estimated tax, interest and penalties or additions to tax and interest on such
penalties and additions to tax.

fiscal year ends on December 31. MP has delivered to IMSI an unaudited draft
version of the MP Financial Statements (as defined below) which is attached as

               3.13 Intellectual Property.

                    3.13.1 MP 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 and as presently
proposed to be conducted (such Intellectual Property Rights being hereinafter
collectively referred to as the "MP IP RIGHTS"), and such rights to use, sell or
license are sufficient for such conduct of its business. MP is the legal and
beneficial owner of all rights, including all copyright and worldwide
distribution rights, to those certain computer software programs, including all
object code, source code, configurations, routines and algorithms contained
therein with annotations and related documentation, known as MediaPaq Manager
together with all alterations, modifications and configurations 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 "MP IP Rights" includes, without limitation, the Software. Any and all
rights to the Software previously owned or held by third parties, including (but
not limited to) the MP Subsidiaries (including those MP Subsidiaries named
below), have been transferred to MP and are owned outright, free and clear of
any claims, liens, security interest, mortgages, encumbrances or obligations.

        Not withstanding the forgoing:

        The MediaPaq Browser includes filters whose technology is licensed from
Snowbound and INSO Corporation, and,

        IMSI is aware that Unysis may make a claim against Media Paq for its use
of alleged Unysis proprietary file format(s).

                    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 




                                       12
<PAGE>   13

a material breach of or default under any instrument, contract, license or other
agreement governing any MP IP Right (the "MP IP RIGHTS AGREEMENTS") and will not
cause the forfeiture or termination, or give rise to a right of forfeiture or
termination, of any MP IP Right or materially impair the right of MP to use,
sell, license, provide or otherwise commercially exploit any MP IP Right or
portion thereof (except where such breach, forfeiture or termination would not
have a Material Adverse Effect on MP ). There are no undisclosed royalties,
honoraria, fees or other payments payable by MP to any person by reason of the
ownership, use, license, sale, exploitation or disposition of the MP IP Rights.

                    3.13.3 Except as otherwise disclosed herein, to the best
knowledge of MediaPaq and MediaPaq shareholders neither the manufacture,
marketing, license, sale, furnishing or intended use of any product or service
currently licensed, utilized, sold, provided or furnished by MP or currently
under development by MP has violated or now violates any license or agreement
between MP 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 MP and the MP Shareholders, threatened claim or litigation
contesting the validity, ownership or right to use, sell, license or dispose of
any MP IP Right nor, to the best knowledge of MP and the MP Shareholders, is
there any basis for any such claim, nor has MP received any notice asserting
that any MP 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 MP and the MP Shareholders, is there any basis for any such
assertion. To the best knowledge of MP and the MP Shareholders, no employee or
agent of or consultant to MP 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 MP to any liability.

                    3.13.4 MP has taken reasonable and practicable steps, in
accordance with prevailing industry standards, designed to protect, preserve and
maintain the secrecy and confidentiality of all material MP IP Rights and all
MP's proprietary rights therein. All officers, employees, agents and consultants
of MP having access to proprietary information have executed and delivered to MP
an agreement regarding the protection of such proprietary information and the
assignment of inventions to MP in the form provided to counsel 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 MP IP Rights and

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 MP IP Rights, the entity (MP or one of
the MP Subsidiaries) which owns or holds such IP Rights.

                    3.13.6 As used herein, the term "INTELLECTUAL PROPERTY
RIGHTS" means, collectively, all worldwide industrial and intellectual property
rights, including, without limitation,

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 MP or to MP's assets, properties, and business. MP 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 MP'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 MP (nor any beneficiaries of any trust that is a MP
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 MP (except with
respect to any interest in less than one percent (1%) of the stock of any
corporation whose stock is publicly traded) other than DataCal Corporation. 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 MP, except for normal compensation for services as an
officer, director or employee thereof that have been disclosed to IMSI and
except for the grant of MP Options (listed in Exhibit B) 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 MP IP Rights or any other Intellectual Property Rights)
that is used in or that pertains to the business of MP, except for the normal
rights of a shareholder.

<PAGE>   15

transactions contemplated hereby will have a material adverse effect on such

                    3.16.3 MP does not have any "employee benefit plan," as

                    3.16.5 There has been no amendment to, written
interpretation or announcement (whether or not written) by MP relating to, or

fiscal year ended 31 December 1996.

                    3.16.6 The group health plans (as defined in Section

schedules, nor any of the certificates or documents to be delivered by MP and/or
the MP Shareholders to IMSI under this Agreement, taken together, contains any
untrue statement of a material fact or omits to state any material fact
necessary in order to make the statements contained herein and therein, in light

disruption to the continuing operations of MP, and minimal cost to IMSI;

incur liability for, or by reason of, such merger of MP's existing 401(k)
savings plan into IMSI's existing 401(k) savings plan and provided further that

401(k) savings plan prior to the Closing.

                                       30
<PAGE>   31

Agreement, and MP and/or the MP Shareholders have not cured such breach prior to

subsection or (iii) the Termination Date.

                10.1.5 MP and the MP Shareholders may terminate this Agreement

Agreement in accordance with this Section 10 will be without further obligation
or liability upon any party in favor of the other party hereto or to its

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

            11.1 Survival of Representations. All representations, warranties
and covenants of MP and the MP 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 that date ("ESCROW RELEASE DATE") which is
the earlier of (i) the termination of this Agreement or (ii) twelve (12) 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 primary MP Shareholders; Mark
Dixon, A. Brent Payne, Brendon Daunt and James Lunt, on behalf of all MP
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




                                       31
<PAGE>   32

costs (hereinafter collectively referred to as "DAMAGES") incurred and arising
out of any inaccuracy, misrepresentation, breach of, or default in, any of the
representations, warranties or covenants given or made by MP and/or the MP
Shareholders in this Agreement or in the MP Disclosure Letter or in any
certificate delivered by or on behalf of MP pursuant hereto (if such inaccuracy,
misrepresentation, breach or default existed at the Closing Date). Any claim of
indemnity made by an Indemnified Person under this Section 11.2 must be asserted
in a writing delivered to the [Escrow Agent by no later than the Escrow Release
Date.]

            11.3 Limitation. Notwithstanding anything herein to the contrary, in
seeking indemnification for Damages under Section 11.2, the Indemnified Persons
shall exercise their remedies with respect to the Escrow Shares and any other
assets deposited in escrow pursuant to the Escrow Agreement. Except for
fraudulent conduct or willful misconduct or breach of any provisions of the
Affiliates Agreement and except as provided in Section 11.5: (i) no MP
Shareholder shall have any liability to an Indemnified Person under Section 11.2
of this Agreement except to the extent of such MP Shareholder's portion of the
Escrow Shares and any other assets deposited under the Escrow Agreement and (ii)
the remedies set forth in this Section 11.3 and the Escrow Agreement shall be
the exclusive remedies of IMSI and the other Indemnified Persons under Section
11.2 of this Agreement or in any cause of action based thereon (subject to the
exceptions in the last sentence of this Section 11.3) against any MP Shareholder
for any inaccuracy, misrepresentation, breach of, or default in, any of the
representations, warranties or covenants given or made by MP or any MP
Shareholder in this Agreement or in any certificate, document or instrument
delivered by or on behalf of MP pursuant hereto or in any cause of action based
thereon (subject to the exceptions in the last sentence of this Section 11.3).
In addition, the indemnification provided for in Section 11.2 shall not apply
unless and until the aggregate Damages for which one or more Indemnified Persons
seeks or has sought indemnification hereunder exceeds a cumulative aggregate of
One Hundred Thousand Dollars ($100,000) (the "BASKET"), in which event the MP
Shareholders shall, subject to the foregoing limitations, be liable to indemnify
the Indemnified Persons for all Damages in excess of the Basket. The limitations
on the indemnification obligations set forth in this Section 11.3 shall not be
applicable to Misconduct Damages (as defined below). As used herein, "MISCONDUCT
DAMAGES" means Damages resulting from fraudulent conduct or willful misconduct
or breach of any provisions of the MP Affiliates Agreement or the Investment
Representation Letter.

            11.4 Notice. Promptly after IMSI becomes aware of the existence of
any potential claim by an Indemnified Person for indemnity from the MP
Shareholders under Section 11.2, IMSI will notify the MP Shareholders of such
potential claim in accordance with the Escrow Agreement 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 MP Shareholders to assist IMSI in the
defense of such claim and will cooperate with the MP Shareholders 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 MP Shareholders are materially prejudiced
thereby. Prior to the settlement of any claim for which IMSI seeks indemnity
from a MP Shareholder, IMSI will provide the MP 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 MP Shareholders from contesting a claim




                                       32
<PAGE>   33

for indemnification hereunder in accordance with the terms and conditions of the
Escrow Agreement.

            11.5 Title Indemnity. In addition to, and separate from, the
foregoing agreement to indemnify set forth in Section 11.2, each MP Shareholder
agrees, severally and not jointly, 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 MP Shareholder to have good, valid and marketable title
to any issued and outstanding shares of MP Stock held (or asserted to have been
held) by such MP 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 MP to have good, valid and
marketable title to all of the outstanding shares of each of the MP Subsidiaries
and any failure of the MP Shareholders collectively to own, of record and
beneficially, 100% of the outstanding shares of MP. A MP shareholder's liability
under the indemnification provided for in this Section 11.5 shall be in addition
to any liability of such MP 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 such MP Shareholder's Escrow Shares.

        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 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.
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 




                                       33
<PAGE>   34

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. Any term or provision of this Agreement
may be amended prior to the Closing by the written consent of IMSI, MP and the
MP Shareholders, and, after the Closing by IMSI and the MP Shareholders (or
their successors in interest). 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 MP
Shareholders and each of MP 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.

            12.7 Expenses. Each party will bear its respective expenses and
legal fees incurred with respect to this Agreement, and the transactions
contemplated hereby; provided, however, that the fees MP will pay to its counsel
and accountants on behalf of MP and the MP Shareholders shall not exceed U.S.
$100,000 in the aggregate without the written consent of IMSI. Any such expenses
in excess of U.S. $100,000 shall be deemed to be Damages (as defined in Section
11.2) and shall be paid by the MP Shareholders from the Escrow Shares, and such
"Damages" shall not be subject to the Basket.

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

            12.9 Notices. All notices and other communications required or
permitted under this Agreement will be in writing and will be either hand
delivered in person, sent by telecopier, sent by certified or registered first
class mail, postage pre-paid, or sent by nationally recognized express courier
service. Such notices and other communications will be effective upon receipt if

            12.10 Construction of Agreement. This Agreement has been negotiated
by the respective parties hereto and their attorneys and the language hereof
will not be construed for or against either party. A reference to a Section or
an exhibit will mean a Section in, or exhibit to, this Agreement unless

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

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

<PAGE>   36

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 MP and provide
MP 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 MP shall use its best efforts to prevent any trading in IMSI Common Stock by
officers, directors, shareholders, employees, agents and consultants of MP
and/or of any MP Subsidiaries.

            12.15 Confidentiality. MP 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.

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 December 11, 1997, in connection with
the registration under the Securities Act of 1933, as amended, of an aggregate
of 20,000 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

        (6) 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 termination's, 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.

        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 




<PAGE>   2

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 P. KOBLICK
                                        ------------------------------------
