DATE, TIME AND PLACE OF SENSE8 SHAREHOLDERS' MEETING
 
     A special meeting of Sense8's shareholders (the "Meeting") to consider and
vote upon a proposal to authorize the transactions contemplated by an Amended
and Restated Agreement and Plan of Merger dated as of April 30, 1998 (the
"Merger Agreement") among EAI, a wholly-owned subsidiary of EAI and Sense8 will
be held on           , 1998 at the offices of Sense8 located at 100 Shoreline
Highway, Suite 282, Mill Valley, California, 94941, at 9:00 a.m., Pacific
Daylight Time. See "The Special Meeting of the Sense8 Shareholders." Pursuant to
the Merger Agreement, Sense8 will be merged with and into EAI (the "Merger").
 
RECORD DATE
 
     Only holders of record of Sense8 common stock, par value $0.001 per share
(the "Sense8 Common Stock") and Sense8 Preferred Stock, par value $0.001 per
share (the "Sense8 Preferred Stock"), at the close of business on April 11, 1998
(the "Record Date") are entitled to vote at the Meeting. At the close of
business on the Record Date, there were 828,693 shares of Sense8 Common Stock
and 308,929 shares of Sense8 Preferred Stock designated as Series A Preferred
Stock ("Sense8 Series A Preferred") outstanding, each of which is entitled to
one vote at the Meeting. There were no shares of Sense8 Preferred Stock
designated as Series B Preferred Stock ("Sense8 Series B Preferred") outstanding
on the Record Date. See "The Special Meeting of the Sense8
Shareholders -- Record Date."
 
REQUIRED VOTE
 
     The representation in person or by proxy of at least a majority of the
issued and outstanding shares of Sense8 Common Stock and Sense8 Preferred Stock
(together, "Sense8 Stock") is necessary to establish a quorum for the
transaction of business at the Meeting. According to the California General
Corporation Law, as amended (the "CGCL"), and Sense8's Articles of
Incorporation, the affirmative vote of a majority of the outstanding shares of
(i) Sense8 Common Stock, and (ii) each series of outstanding Sense8 Preferred
Stock is necessary to approve the Merger Agreement. Thomas B. Coull, the
President and a director of Sense8, and Patrice Gelband, a director of Sense8,
who hold 229,615 and 300,000 shares of Sense8 Common Stock, respectively, have
executed irrevocable proxies in favor of EAI to vote for the approval of the
Merger
                                        1

Agreement. The shares of Sense8 Common Stock held by Mr. Coull and Ms. Gelband
represent a majority of the outstanding shares of Sense8 Common Stock. Evans &
Sutherland Computer Corporation ("E&S"), which holds 220,694 shares of Sense8
Series A Preferred, has executed an irrevocable proxy in favor of EAI to vote
for the approval of the Merger Agreement. The shares of Sense8 Series A
Preferred held by E&S represent a majority of the outstanding shares of Sense8
Series A Preferred. See "The Special Meeting of the Sense8
Shareholders -- Required Vote." Directors and executive officers of Sense8 and
their affiliates beneficially own approximately 65% of the issued and
outstanding shares of Sense8 Common Stock. See "Information Concerning
Sense8 -- Security Ownership."
 
     The consent of the stockholders of EAI is not required to approve the
Merger or the Merger Agreement and will not be sought.
 
PROXIES
 
     All shares of Sense8 Common Stock represented by properly executed and
unrevoked proxies which are received prior to or at the Meeting will be voted in
accordance with the instructions indicated in such proxies. Properly executed
proxies which do not contain voting instructions will be voted FOR approval of
the Merger Agreement. Shareholders are urged to mark the box on the proxy to
indicate how their shares are to be voted. See "The Special Meeting of the
Sense8 Shareholders -- Proxies."
 
THE MERGER
 
     Upon the terms and subject to the conditions contained in the Merger
Agreement, at the effective time of the Merger, (i) Sense8 will be merged with
and into EAI and EAI will continue in existence as the surviving corporation,
(ii) each outstanding share of Sense8 Stock (other than shares with respect to
which dissenters' rights have been perfected and treasury shares) will be
converted into the right to receive a fraction of a share of EAI common stock,
par value $0.01 per share ( "EAI Common Stock"). The conversion ratios for each
of the Sense8 Common Stock, the Sense8 Series A Preferred and the Sense8 Series
B Preferred will differ due to the respective liquidation preferences of the
Sense8 Series A Preferred and the Sense8 Series B Preferred.
 
     Assuming that certain transaction expenses of Sense8 do not exceed current
estimates and that all outstanding convertible notes of Sense8 ("Sense8
Convertible Notes") are converted into Sense8 Preferred Stock on an assumed
Closing Date of June 30, 1998 (the "Closing Date"), upon consummation of the
Merger each share of Sense8 Common Stock would convert into the right to receive
0.082576 of a share of EAI Common Stock, each share of Sense8 Series A Preferred
would convert into the right to receive 0.242135 of a share of EAI Common Stock
and each share of Sense8 Series B Preferred would convert into the right to
receive 0.496962 of a share of EAI Common Stock. The conversion ratios
determined as of the Effective Time may differ slightly from the foregoing
estimates due to additional transaction expenses or failure to convert all
Sense8 Convertible Notes. See "The Merger -- Merger Consideration."
 
     EAI will issue only whole shares of EAI Common Stock in connection with the
Merger. Each holder of Sense8 Common Stock who otherwise would be entitled to
receive a fractional share of EAI Common Stock will instead receive an amount of
cash (without interest) determined by multiplying $42.61725 by the fractional
share interest to which such holder would otherwise be entitled.
 
DISSENTERS' RIGHTS
 
     Under the CGCL, Sense8 shareholders will be entitled to dissent from the
Merger and, if the Merger is consummated, to obtain cash in an amount equal to
the "fair market value" of their Sense8 Stock which may be more or less than the
amount to be received pursuant to the Merger Agreement. Specific procedures are
required to be followed in order to exercise such rights. See "The
Merger -- Dissenters' Rights." The Merger Agreement provides that if holders of
more than twenty percent of the outstanding Sense8 Common Stock shall have
validly exercised their dissenters' rights, EAI may refuse to consummate the
Merger and terminate the Merger Agreement.

APPROVAL OF THE MERGER
 
     The Boards of Directors of EAI and Sense8 have unanimously approved the
consummation of the Merger and the transactions contemplated by the Merger
Agreement. See "The Merger -- Background of the Merger."
 
EFFECTIVE TIME OF THE MERGER
 
     "Effective Time" shall mean the time at which the Merger becomes effective.
The Merger will become effective upon the filing of a properly executed
Agreement of Merger with the California Secretary of State and a properly
executed Certificate of Merger with the Delaware Secretary of State, which is
expected to occur not later than five business days after the satisfaction or
waiver of the conditions to the Merger.
 
CONDITIONS TO THE MERGER; TERMINATION
 
     The consummation of the Merger is conditioned upon the fulfillment of
certain conditions set forth in the Merger Agreement. The Merger Agreement may
be terminated by mutual consent of the Boards of Directors of Sense8 and EAI, by
either EAI or Sense8 if certain conditions have not been satisfied, and in
certain other situations. If Sense8 terminates the Merger Agreement under
certain circumstances, it will be required to make certain payments to EAI and
may be required to make certain additional payments if it consummates or agrees
to consummate certain types of transactions within the 12-month period following
such termination. See "The Merger -- Conditions to Closing," and "-- Termination
and Termination Fee."
 
INTERIM MANAGEMENT AGREEMENT
 
     In connection with the Merger Agreement, Sense8 and EAI entered into an
Interim Management Agreement (the "Management Agreement"). The Management
Agreement provides for the joint management of Sense8 by EAI and Sense8 during
the period (the "Interim Period") from April 11, 1998 through the date of the
consummation of the Merger or termination of the Merger Agreement. Under the
Management Agreement, Thomas Coull resigned on April 11, 1998 as Chief Executive
Officer of Sense8 and retained the title of President of Sense8. The Executive
Vice President of EAI, Martin J. Vanderploeg, Ph.D., began serving as Chief
Executive Officer of Sense8 and reports to the Board of Directors of Sense8. The
Management Agreement provides that Sense8 shall reimburse EAI for the costs
incurred in making EAI's employees, other than Dr. Vanderploeg, available to
Sense8 during the Interim Period, and Sense8 shall indemnify all EAI employees
who render services to Sense8 during the Interim Period from and against any
claims or liabilities relating to their services to Sense8.
 
OTHER NEGOTIATIONS
 
     The Merger Agreement places certain restrictions on the extent to which
Sense8 can negotiate with prospective purchasers other than EAI. See "The
Merger -- No Solicitations."
 
FEDERAL INCOME TAX CONSEQUENCES
 
     The Merger is intended to qualify, to the extent possible, as a tax-free
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended. Tax-free treatment of the Merger for the Sense8
shareholders will depend in part on circumstances occurring after the Merger.
For a discussion of the possible federal income tax consequences of the Merger,
see "The Merger -- Certain Federal Income Tax Consequences."

RESALE RESTRICTIONS
 
     All shares of EAI Common Stock received by Sense8 shareholders in
connection with the Merger will be fully transferable, except that shares of EAI
Common Stock received by persons who are deemed to be "affiliates" (as that term
is defined for purposes of Rule 145 under the Securities Act of 1933, as
amended), of Sense8 at the Effective Time may be resold by such persons only in
certain circumstances. See "The Merger -- Resale of EAI Common Stock Issued in
the Merger; Affiliates."

                                  RISK FACTORS
 
     Certain matters discussed in this Proxy Statement/Prospectus are
forward-looking statements that involve substantial risks and uncertainties that
could cause actual results to differ materially from targets or projected
results. Factors that could cause actual results to differ materially include,
among others, those factors described below. Many of these factors are beyond
EAI's ability to predict or control. Sense8 shareholders are cautioned not to
put undue reliance on forward-looking statements, which statements have been
made as of the date of this Proxy Statement/Prospectus and Sense8 shareholders
should not infer that there has been no change in the affairs of EAI since the
date hereof that would warrant any modification of any forward-looking statement
made in this Proxy Statement/Prospectus. EAI disclaims any intent or obligation
to update publicly these forward-looking statements, whether as a result of new
information, future events or otherwise.
 
     In addition to the other information in this Proxy Statement/Prospectus,
the following factors should be considered carefully by Sense8 shareholders in
evaluating EAI and its business before approving the Merger Agreement.
 
FIXED EXCHANGED RATIO DESPITE CHANGE IN EAI STOCK PRICE
 
     The consideration to be received in the Merger by holders of Sense8 Stock
will be based on a fixed number of shares of EAI Common Stock. See "The
Merger -- Merger Consideration". The fixed exchange ratio will not be adjusted
in the event of any increase or decrease in the market price of EAI Common Stock
between the date hereof and the Effective Time. The price of EAI Common Stock at
the Effective Time may be higher or lower than its price on the date of this
Proxy Statement/Prospectus or the $42.61725 price used in determining the Merger
conversion ratios. Such variations may be the results of changes in the business
operations or prospects of EAI, general market and economic conditions or other
factors.
 
VARIABILITY OF OPERATING RESULTS
 
     EAI has experienced and expects to continue to experience fluctuations in
its quarterly results. EAI's revenues are affected by a number of factors,
including the timing of the introduction of new software product and interactive
products by EAI and its competitors, seasonality of certain customer purchases,
product mix, general economic conditions and EAI's ability to obtain agreements
from publishers and distributors to market EAI's products. EAI's operating
results also will vary significantly depending on changes in pricing, changes in
customer budgets and changes in the volume and timing of orders received during
the quarter, which are difficult to forecast. As a result of the foregoing and
other factors, EAI may experience material fluctuations in future revenues and
operating results on a quarterly or annual basis. Therefore, EAI believes that
period to period comparisons of its revenues and operating results are not
necessarily meaningful and should not be relied upon as indicators of future
performance.
 
TECHNOLOGICAL CHANGE AND MARKET ACCEPTANCE
 
     EAI's success depends on its ability to develop and sell new products,
develop site licensing agreements with major manufacturers in the automotive,
aerospace, heavy equipment and other manufacturing industries, develop its 3D
and 2D software products for new platforms and continue to produce high-quality
interactive products in a timely and cost effective manner. In addition, EAI
must continually anticipate, and adapt its products to, emerging computer
technologies and capabilities, such as enhanced graphics, sound, music, video
and speech generation. The life cycles of EAI's products are difficult to
estimate because the markets that EAI targets are in the early stages of
development and because of uncertainties arising from the effect of future
product enhancements, future developments in hardware and software technology
and future competition. If EAI's products become outdated and lose market share
or if new products or existing product upgrades are not introduced when demanded
by the market or are not accepted by the market, EAI's revenues and operating
results could be materially adversely affected. There is no assurance that EAI
will be able to introduce new products on a timely basis or that such new
products will be accepted in the market.

IMPACT OF ACQUISITIONS
 
     In addition to the proposed acquisition of Sense8, EAI has acquired Rosetta
Technologies, Inc. and Cimtech, Inc., both in November 1997, and will continue
to identify and evaluate acquisition opportunities in the future. Any
acquisition, however, involves inherent uncertainties, such as the effect on the
acquired business of integration into a larger organization and the availability
of management resources to oversee the operations of the acquired business.
EAI's ability to integrate the operations of Sense8 and other acquired companies
is important to its future success. There can be no assurance as to EAI's
ability to integrate new businesses nor as to its success in managing the larger
operations resulting therefrom. Even though an acquired business may have
experienced profitability and growth as an independent company prior to its
acquisition by EAI, there can be no assurance that such profitability and growth
will continue thereafter.
 
DEPENDENCE ON EMERGING MARKET FOR SOFTWARE PRODUCTS AND CUSTOMER CONCENTRATION
 
     The market for enterprise-wide visualization software products in the
automotive, aerospace, heavy equipment and other manufacturing industries is
emerging and dependent on a number of variables, including customer preferences
and the rate of adoption of new technology. There can be no assurance that this
market will continue to grow or that EAI's software products will be accepted by
the market. EAI's growth is dependent in part on significant demand for its
software products. In addition, as EAI increasingly markets its 3D and 2D
visualization software as an enterprise-wide solution, there can be no assurance
that large customers will be willing to invest in EAI's products on a
company-wide basis or that users outside the design and engineering areas will
accept EAI's products. In 1997, sales of software products to one customer
accounted for 19% of EAI's revenues. There can be no assurance that EAI will be
able to continue to sell software products to this customer at 1997 levels or,
if it fails to do so, that EAI will be able to replace this customer with new
customers.
 
DEPENDENCE ON EMERGING MARKET FOR INTERACTIVE PRODUCTS
 
     The market for interactive multimedia software products is emerging and
dependent on a number of variables, including consumer preferences, shipments of
multimedia personal computers, the installed base of multimedia personal
computers and the number of other publishers creating interactive software
products. There can be no assurance that this market will continue to grow. The
market for games and educational multimedia software is characterized by rapid
changes in computer hardware and software technology and is highly competitive
with respect to timely product innovation. EAI's near-term growth is dependent
in part on significant demand for its recently released interactive products and
for its products under development. However, EAI does not typically receive
royalty revenues from a product until the publisher achieves a minimum level of
sales of the product, which may not occur immediately after delivery of the
product to the publisher, if at all. There can be no assurance that EAI's new
interactive products will be accepted by the market or that EAI will be able to
respond effectively to the evolving requirements of the market.
 
RELIANCE ON THIRD PARTIES TO MARKET AND DISTRIBUTE CERTAIN INTERACTIVE PRODUCTS
 
     EAI's strategy has been to rely upon third parties to market and distribute
its interactive products. EAI does not have an exclusive relationship with any
of the current distributors of its interactive products. EAI's relationships
with publishers have involved contracts that address a single product or title
for a specific market area and do not constitute a continuing market and
distribution agreement. There can be no assurance that EAI's relationships with
publishers will continue or that EAI will be able to find other means to market
and distribute its interactive products. Failure to continue such relationships,
establish new relationships or develop independent means of marketing and
distributing interactive products could have a material adverse effect on EAI's
revenues and operating results.
 
RELIANCE ON THIRD PARTIES TO MARKET AND DISTRIBUTE CERTAIN SOFTWARE PRODUCTS
 
     In addition to marketing EAI's software products directly to end users, EAI
has contractual relationships with Hewlett-Packard to jointly market and
Structural Dynamics Research Corporation (SDRC) to jointly
 
                                        9
<PAGE>   17
 
market and distribute certain of EAI's software products. Although these
contracts represent a significant marketing and distribution opportunity for
EAI's software products, there can be no assurance that these contractual
relationships will be successful in creating significant sales or that these
relationships will be continued beyond their contract terms.
 
MANAGEMENT OF GROWTH AND INTERNATIONAL EXPANSION
 
     EAI has experienced and may continue to experience rapid growth which could
place a significant strain on EAI's employees, operating procedures, financial
resources and information systems. EAI plans to introduce a significant number
of new products, increase its production capacity and development expenditures,
expand its sales and marketing initiatives and hire additional employees. Such
activities will require significant managerial expertise. If EAI is unable to
manage its growth effectively, EAI's revenues, operating results and financial
condition could be materially adversely affected. In addition, in connection
with EAI's plans to increase its sales and marketing presence in Europe and
Asia, EAI will be incurring expenses in advance of revenues. If EAI is
unsuccessful in generating sufficient revenues to recover their expenses or is
unable to hire, train and retain experienced international sales and marketing
personnel, EAI's revenues, operating results and financial condition could be
adversely affected. Increased international activity could expose EAI to foreign
currency fluctuations, foreign labor laws and other unforeseen problems.
 
COMPETITION
 
     EAI expects significant competition in each of its two product lines:
 
SOFTWARE PRODUCTS
 
     Large computer companies or companies competing in the CAD/CAE/CAM and
project data management markets could offer products with the same or similar
functionality as offered by EAI. Such companies, some of which have
substantially greater financial and other resources than EAI, include Autodesk
Inc., Dassault Systems, Division Plc., IBM, Parametric Technology Corp., SDRC,
and Silicon Graphics, Inc. Although EAI believes it has a technological
advantage over potential competitors in these markets, maintaining its advantage
will require continuing investment by EAI in research and development and sales
and marketing. There can be no assurance that EAI will have sufficient resources
to make such investments or that such investments will be successful.
 
INTERACTIVE PRODUCTS
 
     The interactive software publishing industry is intensely competitive.
EAI's sales to the educational and consumer markets may be adversely affected by
the increasing number of competitive products. EAI's interactive products will
compete directly against other educational and consumer software products
including multiplayer Internet games. EAI's competitors in this area include a
large number of companies, some of which have substantially greater financial,
technical, marketing and other resources than EAI, such as Broderbund Software
Inc., Condent Corporation International, Digital Domain Inc., GT Interactive
Software Corp., and SoftKey International Inc. Moreover, large corporations,
such as Microsoft Corporation and The Walt Disney Company, which have
substantial bases of intellectual property content and substantial financial
resources, have entered or announced their intention to enter the market for
consumer software.
 
     While EAI believes that most special effects firms target the feature film
and advertising markets, these firms could refocus their efforts in the
commercial markets, an area in which EAI derives a portion of its interactive
product revenue. These special effects firms, some of which have substantially
greater financial, technical, marketing and other resources than EAI, include
Dreamworks SKG, Industrial Light and Magic (a division of Lucasfilm Limited),
and Pixar. In addition, a large number of small companies provide custom
animations to commercial markets as a complement to their primary business of
studio film production, engineering consulting and communications consulting.

<PAGE>   18
 
YEAR 2000 COMPUTER CONVERSION
 
     EAI has developed and implemented a plan to upgrade its information
technology in order to prepare for the year 2000 and has completed conversion of
all critical data processing systems. All of EAI's systems and applications are
2000 compliant. EAI has also initiated communications with its significant
vendors to determine the extent to which EAI's systems may be vulnerable to
third parties' failure to remediate their own 2000 issues. Management currently
does not anticipate such a failure to be an issue. However, operating results
could be impacted if the systems of other companies with whom EAI transacts
business are not compliant in a timely manner.
 
PROTECTION OF PROPRIETARY RIGHTS
 
     EAI's success and ability to compete is dependent in part upon its
extensive proprietary technology and databases. EAI relies primarily on a
combination of copyright, trademark and trade secret laws, employee and third
party non-disclosure and non-competition agreements and other methods to protect
its proprietary rights. There can be no assurance that these measures will
prevent EAI's competitors from obtaining or using EAI's proprietary technology
and databases. Certain of EAI's products include mechanisms intended to prevent
or inhibit unauthorized copying. In addition, EAI packages its software products
with license agreements, which prohibit unauthorized copying of such products.
Unauthorized copying does, however, occur in the software industry, and if a
significant amount of unauthorized copying of EAI's products were to occur,
EAI's revenues and operating results could be adversely affected. The laws of
certain countries in which EAI's products are or may be distributed do not
protect EAI's products and proprietary rights to the same extent as do the laws
of the United States. Furthermore, as the number of software products in the
industry increases and the functionality of these products further overlaps,
software developers may increasingly become subject to infringement claims.
There can be no assurance that third parties will not assert infringement claims
against EAI in the future with respect to current or future products, or that
any such assertion will not require EAI to enter into royalty arrangements or
result in costly litigation.
 
DEPENDENCE ON KEY PERSONNEL
 
     EAI's future success depends in large part on the continued service of its
key technical, marketing, sales and management personnel and on its ability to
continue to attract, motivate and retain highly qualified employees. EAI's key
employees may voluntarily terminate their employment with EAI at any time.
Competition for such employees is intense and the process of locating key
technical and management personnel with the combination of skills and attributes
required to execute EAI's strategy can be lengthy. Accordingly, the loss of the
services of key personnel could have a material adverse effect on EAI's
revenues, operating results and financial condition. EAI maintains key person
insurance covering certain of its executive officers. However, the amount of
insurance may not be sufficient to offset EAI's loss of the services of any of
its executive officers.
 
RISK OF LIABILITY CLAIMS BY CUSTOMERS
 
     Although EAI has not experienced product liability claims by customers, EAI
could experience such claims in the future. EAI's interactive software products
carry a disclaimer that the products should not be used for diagnostic or
treatment purposes and are only for educational and medical reference purposes.
EAI has general liability insurance and insurance for errors and omissions in
the content of its products. If a liability claim were to be made, there can be
no assurance that EAI would be successful in defending against the claim or, if
unsuccessful, that the amount of insurance coverage, if any, would be sufficient
to pay the claim.
 
SHARE PRICE VOLATILITY
 
     The trading price of the EAI Common Stock could be subject to wide
fluctuations in response to quarter to quarter variations in operating results,
changes in earnings estimates by analysts, announcements of technological
innovations or new products by EAI or its competitors, general conditions in the
software and
 
                                       11
<PAGE>   19
 
computer industries and other events or factors. In addition, in recent years
the stock market in general, and the shares of technology companies in
particular, have experienced extreme price fluctuations. This volatility has had
a substantial effect on the market prices of securities issued by many companies
for reasons unrelated to the operating performance of the specific companies.
These broad market fluctuations may adversely affect the market price of the EAI
Common Stock.
 
ANTI-TAKEOVER PROVISIONS
 
     EAI's Certificate of Incorporation and By-laws and Delaware law contain
provisions that may have the effect of delaying, deferring or preventing a
non-negotiated merger or other business combination involving EAI. These
provisions are intended to encourage any person interested in acquiring EAI to
negotiate with and obtain the approval of the Board of Directors in connection
with the transaction. Certain of these provisions may, however, discourage a
future acquisition of EAI not approved by the Board of Directors in which
stockholders might receive an attractive value for their shares or that a
substantial number or even a majority of EAI's stockholders might believe to be
in their best interest. As a result, stockholders who desire to participate in
such a transaction may not have the opportunity to do so. Such provisions could
also discourage bids for the shares of EAI Common Stock at a premium, as well as
create a depressive effect on the market price of the shares of EAI Common
Stock. In addition to the EAI Common Stock, EAI's Certificate of Incorporation
authorizes the issuance of up to 20,000,000 shares of preferred stock. EAI has
no current plans to issue any shares of preferred stock. However, because the
rights and preferences for any series of preferred stock may be set by the Board
of Directors in its sole discretion, EAI may issue preferred stock that has
rights and preferences superior to the rights of holders of shares of the EAI
Common Stock and thus may adversely affect the rights of holders of shares of
the EAI Common Stock. In addition, the Board of Directors has adopted a
Stockholders Rights Plan that may have an anti-takeover effect and may
discourage or prevent takeover attempts not first approved by the Board of
Directors (including takeovers that certain stockholders may deem to be in their
best interests).
 
DIVIDENDS
 
     EAI has not paid any dividends and does not currently anticipate paying
cash dividends in the future. There can be no assurance that EAI will ever pay a
cash dividend.

                 THE SPECIAL MEETING OF THE SENSE8 SHAREHOLDERS
 
DATE, TIME AND PLACE
 
     The special meeting (the "Meeting") of the shareholders of Sense8
Corporation, a California corporation ("Sense8"), will be held on          ,
1998 at the offices of Sense8 located at 100 Shoreline Highway, Suite 282, Mill
Valley, California 94941 at 9:00 a.m. Pacific Daylight Time.
 
PURPOSE OF THE MEETING
 
     At the Meeting, the shareholders of Sense8 will be asked to consider and
vote upon a proposal to approve an Amended and Restated Agreement and Plan of
Merger dated as of April 30, 1998 (the "Merger Agreement") among Engineering
Animation, Inc., a Delaware corporation ("EAI"), a wholly-owned subsidiary of
EAI, and Sense8, pursuant to which, among other things, Sense8 will be merged
with and into EAI (the "Merger"). See "The Merger."
 
RECORD DATE
 
     Only holders of record of Sense8 common stock, par value $0.001 per share
(the "Sense8 Common Stock") and Sense8 Preferred Stock, par value $0.001 per
share (the "Sense8 Preferred Stock"), at the close of business on April 11, 1998
(the "Record Date") are entitled to vote at the Meeting. At the close of
business on the Record Date, there were 828,693 shares of Sense8 Common Stock
and 308,929 shares of Sense8 Preferred Stock designated as Series A Preferred
Stock ("Sense8 Series A Preferred") outstanding, each of which is entitled to
one vote at the Meeting. There were no shares of Sense8 Preferred Stock
designated as Series B Preferred Stock ("Sense8 Series B Preferred") outstanding
on the Record Date.
 
REQUIRED VOTE
 
     The representation in person or by proxy of at least a majority of the
issued and outstanding shares of Sense8 Stock is necessary to establish a quorum
for the transaction of business at the Meeting. According to the California
General Corporation Law, as amended, (the "CGCL"), and Sense8's Articles of
Incorporation, the affirmative vote of a majority of the outstanding shares of
(i) Sense8 Common Stock, and (ii) each series of outstanding Sense8 Preferred
Stock is necessary to approve the Merger Agreement. Thomas B. Coull, the
President and a director of Sense8, and Patrice Gelband, a director of Sense8,
who hold 229,615 and 300,000 shares of Sense8 Common Stock, respectively, have
executed irrevocable proxies in favor of EAI to vote for the approval of the
Merger Agreement. The shares of Sense8 Common Stock held by Mr. Coull and Ms.
Gelband represent a majority of the outstanding shares of Sense8 Common Stock.
Evans & Sutherland Computer Corporation ("E&S"), which holds 220,694 shares of
Sense8 Series A Preferred, has executed an irrevocable proxy in favor of EAI to
vote for the approval of the Merger Agreement. The shares of Sense8 Series A
Preferred held by E&S represent a majority of the outstanding shares of Sense8
Series A Preferred. Directors and executive officers of Sense8 and their
affiliates beneficially own approximately 65% of the issued and outstanding
shares of Sense8 Common Stock.
 
     The consent of the stockholders of EAI is not required to approve the
Merger or the Merger Agreement and will not be sought.
 
PROXIES
 
     All shares of Sense8 Stock represented by properly executed and unrevoked
proxies which are received prior to or at the Meeting will be voted in
accordance with the instructions indicated in such proxies. Properly executed
proxies which do not contain voting instructions will be voted FOR approval of
the Merger Agreement. Shareholders are urged to mark the box on the proxy to
indicate how their shares are to be voted.
 
     If an executed proxy is returned and the shareholder has abstained from
voting on approval of the Merger Agreement, the shares of Sense8 Stock
represented by such proxy will be considered present at the Meeting for purposes
of determining a quorum and for purposes of calculating the vote, but will not
be considered to have been voted in favor of the Merger Agreement. Because
approval of the Merger Agreement requires the
                                       13
<PAGE>   21
 
affirmative vote of at least a majority of the issued and outstanding shares of
Sense8 Stock, abstentions will have the same effect as a vote against approval
of the Merger Agreement.
 
     It is not expected that any matter other than those referred to in this
Proxy Statement/Prospectus will be brought before the Meeting. If, however,
other matters are properly presented, the persons named as proxies will vote in
accordance with their judgment with respect to such matters, unless authority to
do so is withheld in the proxy.
 
     Any Sense8 shareholder who executes and returns a proxy may revoke such
proxy at any time before it is voted by (i) providing written notice to the
Secretary of Sense8 at 100 Shoreline Highway, Suite 282, Mill Valley, California
94941, (ii) granting a subsequent proxy or (iii) appearing in person and voting
at the Meeting. Attendance at the Meeting will not in and of itself constitute
revocation of a proxy.
 
     The approval of EAI's stockholders is not required for EAI to consummate
the Merger.

                                   THE MERGER
 
     Set forth below is a brief description of various provisions of the Merger
Agreement with references to specific sections. This summary does not purport to
be complete and is qualified in its entirety by reference to the complete Merger
Agreement which is attached to this Proxy Statement/Prospectus as Appendix A and
is incorporated by reference herein. The shareholders of Sense8 are urged to
read the Merger Agreement in its entirety.
 
BACKGROUND OF THE MERGER
 
     On February 4, 1997, several of Sense8's senior managers traveled to EAI's
Ames facility to present Sense8's technology and products to several of EAI's
senior managers including Dr. Martin J. Vanderploeg, EAI's Executive Vice
President and Chief Technology Officer. The purpose of this meeting was for each
company to learn more about the other's products and technologies, with a focus
on developing a mutually beneficial strategic relationship. Dr. Vanderploeg and
Dr. Matthew M. Rizai, President and Chief Executive Officer of EAI, then met
with Sense8's board of directors and senior management on February 21, 1997, at
Sense8's Mill Valley headquarters. At this meeting, discussions continued
regarding the potential for a strategic relationship, which included the
possibility of a merger.
 
     On February 28, 1997, EAI purchased from Sense8 a license to distribute the
"Device Server", a stand alone WorldToolKit application that provided support
for virtual reality input devices to EAI's VisMockUp program. On March 18, 1997,
Sense8 and EAI jointly announced a strategic partnership to collaboratively meet
the growing 3D prototyping and automation needs of the design and manufacturing
industries. This relationship was to range from technology integration to joint
product development.
 
     In late March 1997, Dr. Vanderploeg contacted Thomas B. Coull, President of
Sense8, to begin discussing the possibility of a merger. They explored, and
ultimately rejected, the possibility of a merger of the two companies at that
time.
 
     In June 1997, senior management of Sense8 decided to explore strategic and
financial alternatives to support the business goals of bringing Sense8's
products and services to mainstream commercial markets as well as to provide
financial stability for growth. Sense8 engaged Communications Capital Partners
on August 7, 1997 to develop and assist in Sense8's evaluation of alternatives
for the company. During the first week of August 1997, Patricia E. Glovsky, a
partner of Communications Capital Partners, contacted Dr. Rizai to discuss his
interest in acquiring Sense8. Dr. Rizai declined to pursue acquisition
discussions at that time.
 
     Between August 1997 and January 1998, Sense8 and Communication Capital
Partners contacted a number of companies to explore the potential for a
strategic investment in, or acquisition of, Sense8. In January 1998, Ms. Glovsky
contacted Dr. Rizai to discuss the possibility of an acquisition. At that time,
Dr. Rizai arranged for Jerome M. Behar, Chief Financial Officer of EAI, to
handle the discussions. Mr. Behar began to pursue discussions in February 1998.
After confirming that EAI would proceed with acquisition discussions in
February 1998, Mr. Coull contacted Dr. Vanderploeg to continue the discussions
of early 1997.
 
     On February 26, 1998, Sense8 entered into a binding letter of intent (the
"LOI") with E&S, a holder of Sense8 Preferred Stock, for a financing of Sense8.
The agreement included, among other things, a right of first refusal in favor of
E&S to match any offers to purchase Sense8 received through April 20, 1998, as
well as an exclusive option (the "Option") to acquire Sense8 during the period
commencing April 21, 1998 through May 31, 1998 for a purchase price of
$2,750,000 in cash and the assumption of all Sense8's liabilities. In addition,
E&S agreed to waive its rights to receive distributions as a Sense8 shareholder
in the event E&S decided to acquire Sense8. E&S subsequently waived its right of
first refusal with respect to the Merger and deferred its Option until
consummation or termination of the Merger.
 
     Also in February 1998, senior management of EAI stated its interest to
pursue the acquisition of Sense8. On March 3, 1998, Sense8's Board of Directors
accompanied by senior management and Ms. Glovsky, met with EAI senior management
in Ames, Iowa to determine financial, strategic and corporate objectives for the
companies, in addition to discussing the terms of a possible merger.
 
                                       15
<PAGE>   23
 
     On the afternoon of March 10, 1998, Mr. Behar and Jamie A. Wade, Vice
President of Administration and General Counsel for EAI, made a financial
proposal to Communication Capital Partners, the investment banker representing
Sense8. On March 14, Mr. Coull and Patrice Gelband, a Sense8 board member, Ms.
Glovsky, Richard W. Beatty, managing partner of Communications Capital Partners,
and Mr. Behar, met to further discuss the financial considerations of merging
both companies. That evening, the parties agreed in principle on the terms of
the merger and documented their agreement in a non-binding letter of intent.
 
     Between March 23 and April 4, 1998 numerous telephone conversations
occurred to address the terms of the potential merger, the operational issues
involved in a potential combining of Sense8 and EAI, and the structure of the
transaction. The Sense8 Board of Directors reviewed the final Merger Agreement
and the ancillary agreements, including the interim management agreement, and
approved such agreements on April 11. As of April 30, 1998, the parties to the
Merger Agreement executed an amended and restated merger agreement to change the
structure of the Merger so that Sense8 would merge directly into EAI.
 
SENSE8'S REASONS FOR THE MERGER
 
     Certain matters discussed below are forward-looking statements that involve
substantial risks and uncertainties that could cause actual results to differ
materially from targets or projected results. Factors that could cause actual
results to differ materially include, among others, those factors described in
"Risk Factors." Many of these factors are beyond Sense8's ability to predict or
control. Sense8 shareholders are cautioned not to put undue reliance on
forward-looking statements, which statements have been made as of the date of
this Proxy Statement/Prospectus and Sense8 shareholders should not infer that
there has been no change in the affairs of Sense8 or EAI since the date hereof
that would warrant any modification of any forward-looking statement made in
this Proxy Statement/Prospectus. Sense8 and EAI disclaim any intent or
obligation to update publicly these forward-looking statements, whether as a
result of new information, future events or otherwise.
 
     FINANCIAL RESOURCES.  During 1997 and into 1998 Sense8 was experiencing
serious cash flow difficulties. The Merger will permit the combined company to
continue to develop Sense8 technology using EAI's financial resources. The
Sense8 Board believes such resources give Sense8 the opportunity to focus on its
core business capabilities and grow the combined companies' operations, and well
as to pay down or pay off certain of its outstanding liabilities.
 
     SUPERIOR OFFER BY EAI.  Under the terms of the LOI with E&S, E&S
subsequently deferred the acquisition of Sense8 during the period commencing
April 21, 1998 through May 31, 1998 for a total purchase price of (i) $2,750,000
in cash, (ii) the assumption of all Sense8's liabilities, and (iii) an agreement
to waive its rights to receive distributions as a Sense8 shareholder should E&S
decide to acquire Sense8. EAI's offer to acquire Sense8 included a purchase
price which was higher than the Option price negotiated by E&S.
 
     COMPETITIVE ADVANTAGE.  The combined company expects to offer software
products that provide enterprise-wide product visualization as well as
specialized virtual reality capabilities which should give the combined company
greater market acceptance and competitive advantage.
 
     ECONOMIES OF SCALE.  Sense8 will have access to EAI's distribution
infrastructure which will provide more cost effective product development,
shipping and customer billing.
 
     SHAREHOLDER LIQUIDITY.  The proposed merger will provide liquidity in the
public market for Sense8's shareholders and option holders by replacing the
illiquid Sense8 Stock and options with publicly-traded EAI Common Stock and
options to purchase such EAI Common Stock.
 
     In the course of its deliberations, the Sense8 Board reviewed and
considered the following additional factors: (i) the additional terms and
conditions of the Merger Agreement, including the amount and form of the
consideration; (ii) information regarding EAI's and Sense8's respective
businesses, prospects, financial performance, financial condition, operations
and technology; (iii) the expectation that the Merger will permit Sense8
shareholders to exchange their shares of Sense8 Common Stock for EAI Common
Stock on a tax-free basis; (iv) an evaluation by the Sense8's management of the
historical strategic relationship between Sense8
 
                                       16
<PAGE>   24
 
and EAI; (v) Sense8's financial condition and liquidity issues; and (vi) the
economic alternatives currently available to Sense8.
 
     The Sense8 Board also considered the following potentially negative
factors: (i) the potential disruption of Sense8's business that might result
from employee uncertainty and lack of focus following announcement of the Merger
and during the integration of the operations of Sense8 and EAI; (ii) the various
conditions to the Merger and the possibility that the Merger might not be
consummated; (iii) the risk that the other benefits sought to be achieved in the
Merger will not be achieved; and (iv) the other risks described above under
"Risk Factors."
 
     The foregoing discussion of the information and factors considered and
given weight by the Sense8 Board is not intended to be exhaustive. In the view
of the variety of factors considered in connection with its evaluation of the
Merger, the Sense8 Board did not find it practicable to and did not quantify or
otherwise assign relative weights to the specific factors and information
considered in reaching its determination. In addition, individual members of the
Sense8 Board may have given different weights to different factors. Moreover,
there can be no assurance that any of the expectations set forth in the
preceding paragraphs will be fulfilled or that any of the expected benefits of
the Merger will be realized.
 
SENSE8 BOARD APPROVAL AND RECOMMENDATION OF THE MERGER
 
     For the reasons stated under "Sense8's Reasons for the Merger," the Sense8
Board believes that the Merger Agreement is fair to, and in the best interests
of, Sense8 and the holders of Sense8 securities. THE BOARD OF DIRECTORS OF
SENSE8 UNANIMOUSLY HAS APPROVED THE MERGER AND RECOMMENDS THAT THE SHAREHOLDERS
OF SENSE8 VOTE FOR ITS ADOPTION.
 
EAI REASONS FOR THE MERGER
 
     Certain matters discussed below are forward-looking statements that involve
substantial risks and uncertainties that could cause actual results to differ
materially from targets or projected results. Factors that could cause actual
results to differ materially include, among others, those factors described in
"Risk Factors." Many of these factors are beyond EAI's ability to predict or
control. Sense8 shareholders are cautioned not to put undue reliance on
forward-looking statements, which statements have been made as of the date of
this Proxy Statement/Prospectus and Sense8 shareholders should not infer that
there has been no change in the affairs of EAI since the date hereof that would
warrant any modification of any forward-looking statement made in this Proxy
Statement/Prospectus. EAI disclaims any intent or obligation to update publicly
these forward-looking statements, whether as a result of new information, future
events or otherwise.
 
     The Merger fits with EAI's growth strategy to provide customers throughout
an enterprise with a full spectrum of product data visualization solutions, from
desktop product visualization to high-end simulation and immersive display. In
particular, the Merger will enhance EAI's leadership in the MCAD market while
strengthening EAI's ability to provide customers with a broad offering of
product visualization solutions. EAI believes that Sense8's simulation and
immersive 3D solutions can be successfully integrated with EAI's VisProducts to
provide customers a complete solution for accessing, viewing and analyzing
large, complex models and immersively interacting with digital project data. EAI
believes that the products resulting from the integration of Sense8's technology
into EAI's VisProducts will allow EAI to expand its offerings to existing
customers and to attract new customers.
 
MERGER CONSIDERATION
 
     Upon the terms and subject to the conditions contained in the Merger
Agreement, at the Effective Time of the Merger, (i) Sense8 will be merged with
and into EAI and EAI will continue in existence as the surviving corporation,
(ii) each outstanding share of Sense8 Common Stock (other than shares with
respect to which dissenters' rights have been perfected ("Dissenting Shares")
and shares to be canceled pursuant to clause (v) below) will be converted into
the right to receive that fraction of a share of EAI Common Stock equal to the
Exchange Ratio (as defined below), (iii) each outstanding share of Sense8
Series A Preferred (other than Dissenting Shares and shares to be canceled
pursuant to clause (v) below) will be converted into
                                       17
<PAGE>   25
 
the right to receive a preference distribution of 0.159560 of a share of EAI
Common Stock (the "Per Share Series A Preference Amount") and that fraction of a
share of EAI Common Stock equal to the Exchange Ratio, (iv) each outstanding
share of Sense8 Series B Preferred (other than Dissenting Shares and shares to
be canceled pursuant to clause (v) below) will be converted into the right to
receive a preference distribution of 0.414386 of a share of EAI Common Stock
(the "Per Share Series B Preference Amount") and that fraction of a share of EAI
Common Stock equal to the Exchange Ratio, and (v) each share of Sense8 Stock
owned by Sense8 as treasury shares or owned directly or indirectly by Sense8,
EAI, or a wholly-owned subsidiary of EAI will be canceled and will cease to
exist, and no stock of EAI or other consideration will be delivered in exchange
therefor.
 
     Pursuant to the Merger Agreement, the exchange ratio in the Merger (the
"Exchange Ratio") will be determined as follows: Each share of Sense8 Stock
shall be exchanged for that number of shares of EAI Common Stock equal to the
quotient, carried to six decimal places, of (x) the number obtained by dividing
the Remaining Total Merger Consideration (as defined below) by the total of the
number of shares of Sense8 Stock outstanding immediately prior to the Effective
Time (omitting any shares of Sense8 Common Stock issued after April 11, 1998 as
a result of the exercise of an option to purchase Sense8 Common Stock) plus the
number of shares of Sense8 Stock issuable upon the exercise of all warrants to
purchase Sense8 Stock ("Sense8 Warrants") outstanding immediately prior to the
Effective Time, divided by (y) $42.61725. The "Remaining Total Merger
Consideration" is the difference of (i) the Total Merger Consideration (as
defined below) less (ii) the Series A Preference Amount (as defined below) and
the Series B Preference Amount (as defined below).
 
     The total consideration payable to holders of Sense8 Stock and Sense8
Warrants upon consummation of the Merger (the "Total Merger Consideration")
shall equal (i) $6,793,089 minus (ii) any legal fees, 1996 audit costs or
brokers' costs of Sense8 as of the Closing Date which relate to the Merger and
which are not reflected on the March 31, 1998 consolidated balance sheet of
Sense8, attached as Exhibit C to the Merger Agreement ("Additional Sense8
Costs"), plus (iii) the principal amount and converted interest of any Sense8
Convertible Notes which are converted prior to the Effective Time.
 
     Assuming the conversion of all Sense8 Convertible Notes on the Closing
Date, the preference amount for the Series A Preferred Stock (the "Series A
Preference Amount") will equal $2,383,427, which will equal $6.80 times the
total of the number of shares of Sense8 Series A Preferred outstanding
immediately prior to the Effective Time plus the number of shares of Sense8
Series A Preferred issuable upon (i) the exercise of all Sense8 Warrants to
purchase Sense8 Series A Preferred outstanding immediately prior to the
Effective Time and (ii) the conversion of the principal and accrued interest of
all Sense8 Convertible Notes on the Closing Date. Assuming the conversion of all
Sense8 Convertible Notes on the Closing Date, the preference amount for the
Series B Preferred Stock (the "Series B Preference Amount") will equal $562,930,
which will equal $17.66 times the total of the number of shares of Sense8 Series
B Preferred outstanding immediately prior to the Effective Time plus the number
of shares of Sense8 Series B Preferred issuable upon (i) the exercise of all
Sense8 Warrants to purchase Sense8 Series B Preferred outstanding immediately
prior to the Effective Time and (ii) the conversion of the principal and accrued
interest of all Sense8 Convertible Notes on the Closing Date.
 
     If (i) there are no Additional Sense8 Costs, and (ii) all Sense8
Convertible Notes are converted on an assumed Closing Date of June 30, 1998, the
Exchange Ratio will be 0.082576 of a share of EAI Common Stock. In that event,
upon consummation of the Merger each share of Sense8 Common Stock would convert
into the right to receive 0.082576 of a share of EAI Common Stock (the Exchange
Ratio), each share of Sense8 Series A Preferred would convert into the right to
receive 0.242135 of a share of EAI Common Stock (the Exchange Ratio plus the Per
Share Series A Preference Amount) and each share of Sense8 Series B Preferred
would convert into the right to receive 0.496962 of a share of EAI Common Stock
(the Exchange Ratio plus the Per Share Series B Preference Amount). The Exchange
Ratio as of the Effective Time may differ slightly from the foregoing estimate
due to Additional Sense8 Costs or failure to convert all Sense8 Convertible
Notes.
 
     EAI will issue only whole shares of EAI Common Stock in connection with the
Merger. Each holder of Sense8 Common Stock who otherwise would be entitled to
receive a fractional share of EAI Common Stock
 
                                       18
<PAGE>   26
 
will instead receive an amount of cash (without interest) determined by
multiplying $42.61725 by the fractional share interest to which such holder
would otherwise be entitled. [Article III]
 
EFFECTIVE TIME OF THE MERGER
 
     "Effective Time" shall mean the time at which the Merger becomes effective.
The Merger will become effective upon the filing of a properly executed
Agreement of Merger with the California Secretary of State and a properly
executed Certificate of Merger with the Delaware Secretary of State, which EAI
and Sense8 expect will occur not later than five business days after the
satisfaction or waiver of the conditions to the Merger. See "-- Conditions to
Closing."
 
CONVERSION OF SHARES IN THE MERGER
 
     All of the shares of Sense8 Stock converted into EAI Common Stock pursuant
to the Merger will no longer be outstanding and will automatically be canceled
and cease to exist at the Effective Time, and each certificate previously
representing any such Sense8 Stock (a "Certificate") will thereafter represent
the right to receive (i) a certificate representing the number of whole shares
of EAI Common Stock and (ii) cash in lieu of fractional shares into which the
shares of Sense8 Stock represented by such Certificate have been converted. If,
prior to the Effective Time, the outstanding shares of EAI Common Stock or
Sense8 Stock are increased, decreased, changed into or exchanged for a different
number or kind of shares or securities as a result of a reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split, or other similar change in capitalization, then EAI and Sense8 have
agreed that an appropriate and proportionate adjustment will be made to the
Exchange Ratio. [Section 2.3]
 
     At the Effective Time, all shares of Sense8 Stock that are owned by Sense8
as treasury stock or owned, directly or indirectly, by Sense8, EAI or any
wholly-owned subsidiary of EAI will be canceled and will cease to exist, and no
stock of EAI or other consideration will be delivered in exchange therefor. All
shares of EAI Common Stock that are owned by Sense8 will become treasury stock
of EAI. [Section 2.3(h)]
 
EXCHANGE OF SHARES
 
     Upon proper surrender of a Certificate representing all of the issued and
outstanding shares of Sense8 Stock owned by the surrendering Sense8 shareholder
for exchange and cancellation to EAI, the holder of such Certificate will be
entitled to receive at the Closing in exchange therefor (i) a certificate
representing that number of whole shares of EAI Common Stock to which such
holder of Sense8 Stock has become entitled, and (ii) a check representing the
amount of any cash in lieu of fractional shares which such holder has the right
to receive. No interest will be paid or accrued on any cash in lieu of
fractional shares payable to holders of Certificates. [Section 2.4]
 
     After the Effective Time, there will be no transfers on Sense8's stock
transfer books of shares of Sense8 Stock. [Section 2.3(i)]
 
WARRANTS TO ACQUIRE SENSE8 COMMON STOCK
 
     At the Effective Time, each outstanding Sense8 Warrant shall be assumed by
EAI. Each such Sense8 Warrant shall thereafter be deemed to constitute a warrant
to acquire, on the same terms and conditions as were applicable under such
Sense8 Warrant, (i) the same number of shares of EAI Common Stock as such Sense8
Warrant would have been exchangeable for had such Sense8 Warrant been exercised
in full immediately prior to the Effective Time and (ii) at an exercise price
per share (rounded up to the nearest whole cent) equal to (A) the aggregate
exercise price for the shares of Sense8 Common Stock otherwise purchasable
pursuant to such Sense8 Warrant divided by (B) the number of shares of EAI
Common Stock deemed to be purchasable under such warrant to acquire EAI Common
Stock; provided, however, that the number of shares of EAI Common Stock that may
be purchased upon exercise of such Sense8 Warrant shall not include any
fractional share and, upon exercise of such Sense8 Warrant, a cash payment shall
be made for any fractional share based upon the closing price of a share of EAI
Common Stock as reported on the Nasdaq Stock Market National Market ("NNM") on
the trading day immediately preceding the date of exercise. As
                                       19
<PAGE>   27
 
soon as practicable after the Effective Time, EAI shall deliver to the holders
of Sense8 Warrants appropriate notices setting forth such holders' rights and
the agreements evidencing the grants of such Sense8 Warrants shall be deemed to
be appropriately amended so that such Sense8 Warrants shall represent rights to
acquire EAI Common Stock on terms and conditions as contained in the outstanding
Sense8 Warrants (subject to certain adjustments). [Section 2.5]
 
OPTIONS TO ACQUIRE SENSE8 COMMON STOCK
 
     At the Effective Time, each outstanding option to purchase Sense8 Common
Stock (the "Sense8 Options"), whether vested or unvested, shall be assumed by
EAI. Each such Sense8 Option so assumed by EAI under the Merger Agreement shall
continue to have and be subject to the same terms and conditions set forth in
the applicable Sense8 Stock Option immediately prior to the Effective Time. Each
such Sense8 Option shall thereafter be deemed to constitute an option to
acquire, on the same terms and conditions as were applicable under such Sense8
Option, (i) the same number of shares of EAI Common Stock as such Sense8 Option
would have been exchangeable for had such Sense8 Option been exercised in full
immediately prior to the Merger and (ii) at an exercise price per share (rounded
up to the nearest whole cent) equal to (A) the aggregate exercise price for the
shares of Sense8 Common Stock otherwise purchasable pursuant to such Sense8
Option divided by (B) the number of shares of EAI Common Stock deemed to be
purchasable under such option to acquire EAI Common Stock; provided, however,
that the number of shares of EAI Common Stock that may be purchased upon
exercise of such Sense8 Option shall not include any fractional share and, upon
exercise of such Sense8 Option, a cash payment shall be made for any fractional
share based upon the closing price of a share of EAI Common Stock as reported on
the NNM on the trading day immediately preceding the date of exercise. As a
condition to EAI's obligations to consummate the Merger, each holder of a Sense8
Option, which by its terms does not automatically convert in the Merger into an
option to purchase EAI Common Stock, shall have consented to the above described
assumption pursuant to a written agreement or instrument signed by such holder.
As soon as practicable after the Effective Time, EAI shall deliver to the
holders of Sense8 Options appropriate notices setting forth such holders' rights
and the agreements evidencing the grants of such Sense8 Options shall be deemed
to be appropriately amended so that such Sense8 Options shall represent rights
to acquire EAI Common Stock on terms and conditions as contained in the
outstanding Sense8 Options (subject to certain adjustments). [Section 2.6]
 
     Within three business days following the Closing Date, EAI will file a
registration statement on Form S-8 covering the Sense8 Options and shall use its
reasonable efforts to maintain the effectiveness of such registration statement
or registration statements (and maintain the current status of the prospectus or
prospectuses referred to therein) for so long as such options remain
outstanding. [Section 2.6(c)]

with reference to a Material Adverse Effect (as defined in the Merger Agreement)

                                       21

no amendment, extension or waiver of the Merger Agreement which reduces the
amount or changes the form of the consideration to be delivered to the holders
of Sense8 Stock may be effected unless the consent of the Sense8 shareholders is

TERMINATION AND TERMINATION FEE
 
     The Merger Agreement may be terminated and the Merger may be abandoned
anytime prior to the Effective Time by the written mutual consent of the EAI and
Sense8 Boards of Directors. The Merger Agreement may be terminated in certain
other circumstances, as follows:
 
          (i) by either the Sense8 or the EAI Board of Directors, if any
     governmental authority required to grant a regulatory approval has denied
     approval of the Merger, or any governmental authority of competent
     jurisdiction has issued an order permanently enjoining or otherwise
     prohibiting the consummation of the transactions contemplated by the Merger
     Agreement;
 
          (ii) by either the Sense8 or the EAI Board of Directors (provided that
     the terminating party is not then in material breach of any representation,
     warranty, covenant or other agreement contained in the Merger Agreement),
     if (x) there has been a material breach of any of the representations or
     warranties or any of the covenants or agreements contained in the Merger
     Agreement on the part of the other party, which breach is not cured within
     30 days following written notice to the party committing such breach, or
     which breach, by its nature or timing, cannot be cured prior to June 30,
     1998, (y) the Closing shall not have occurred on or before June 30, 1998
     provided that neither Board of Directors shall be entitled to terminate the
     Merger Agreement pursuant to (y) if the reason the Closing has not occurred
     by such date is because any governmental authority which is required to
     grant a regulatory approval in connection with the Merger has failed to
     act, this Registration Statement shall have been filed but shall not yet
     have been declared effective, the Meeting shall not have occurred in
     accordance with the requirements of the
 
                                       22
<PAGE>   30
 
     CGCL, or some similar event beyond the control of both parties shall not
     have occurred by such date, or (z) the Closing shall not have occurred on
     or before August 31, 1998; or
 
          (iii) by the Sense8 Board of Directors (after consulting with its
     legal counsel), if such action is required for the Board of Directors to
     comply with its fiduciary duties to Sense8 and its shareholders; provided,
     however, that if such action is taken by Sense8, then within two days of
     such termination, Sense8 shall reimburse EAI for its out-of-pocket expenses
     incurred in connection with the transactions contemplated by the Merger
     Agreement; and provided, further, that if Sense8 consummates any
     transaction pursuant to a Takeover Proposal (as defined below) (x) within
     12 months following the date of the Merger Agreement, or (y) pursuant to a
     definitive agreement executed by Sense8 during such 12-month period, then
     Sense8 shall also promptly pay to EAI $300,000 upon the closing of such
     transaction; provided, however, if the Meeting shall have occurred and the
     Sense8 shareholders have voted with respect to approval of the Merger and
     the vote necessary to approve the Merger is not received, then the Merger
     Agreement shall automatically terminate as of the date of the Meeting and,
     within two days of such termination, Sense8 will pay to EAI $75,000 as
     reimbursement for EAI's out-of-pocket expenses incurred in connection with
     the transactions contemplated in the Merger Agreement. [Section 8.1]
 
NO SOLICITATIONS
 
     The Merger Agreement places certain restrictions on the extent to which
Sense8 may negotiate with prospective purchasers other than EAI. The Merger
Agreement specifically provides that Sense8 shall not, and it shall use its best
efforts to cause its directors, officers, employees and shareholders, and all
investment bankers, attorneys or other advisors or representatives retained by
Sense8 not to, (i) solicit or encourage the submission of any Takeover Proposal
(as hereinafter defined), (ii) participate in any discussions or negotiations
regarding, or furnish to any third party any information with respect to, or
take any other action to facilitate any inquiries or the making of any proposal
that constitutes, a Takeover Proposal, (iii) make or authorize any statement or
recommendation in support of any Takeover Proposal or (iv) enter into any
agreement with respect to any Takeover Proposal.
 
     Notwithstanding the foregoing paragraph, the directors, executive officers
or shareholders of Sense8, or the investment bankers, attorneys, or other
advisors or representatives of Sense8 may participate in discussions or
negotiations with, or furnish information to, any third party that makes a
Takeover Proposal if all of the following events shall have occurred: (i) EAI
has been notified in writing of such Takeover Proposal within 24 hours of
Sense8's receipt thereof, including the identity of the party making the
Takeover Proposal and the specific terms and conditions thereof, and has been
given copies of such Takeover Proposal; (ii) such third party has made a written
Takeover Proposal to the Sense8 Board of Directors, which proposal identifies a
price or range of values to be paid and based on the advice of Sense8's
investment bankers, the Sense8 Board of Directors has determined that such
Takeover Proposal is financially more favorable to the shareholders of Sense8
than the terms of the Merger; (iii) the Sense8 Board of Directors has
determined, based on the advice of Sense8's investment bankers, that such third
party is financially capable of consummating the transactions specified in such
Takeover Proposal; and (iv) the Sense8 Board of Directors has determined, after
consultation with its outside legal counsel, that its fiduciary duties require
it to furnish information to and negotiate with such third party.
Notwithstanding the foregoing, however, Sense8 is prohibited from providing any
non-public information to such third party unless (x) prior to the date thereof
Sense8 has provided such information to EAI, (y) Sense8 has notified EAI in
advance of any such proposed disclosure of non-public information and has
provided EAI with a description of the information Sense8 intends to disclose,
and (z) Sense8 provides such non-public information pursuant to a nondisclosure
agreement in a form satisfactory to EAI. In addition to the foregoing
requirements, Sense8 shall not accept or enter into any agreement concerning a

     For purposes of the Merger Agreement, "Takeover Proposal" is defined as any
proposal or offer for a merger, consolidation or other business combination
involving Sense8 or any proposal or offer to acquire a material equity interest
in, or a substantial portion of the assets of, Sense8, other than by EAI as
contemplated by the Merger Agreement. [Section 6.6]
 
REGISTRATION AND LISTING
 
     EAI has agreed to register under the Securities Act of 1933, as amended
(the "Securities Act") the shares of EAI Common Stock to be issued in connection
with the Merger and to use its reasonable efforts to obtain all necessary state
securities or "blue sky" qualifications, permits and approvals required to
consummate the transactions contemplated by the Merger Agreement. Sense8 has
agreed to cooperate with EAI in taking such actions. [Section 6.1]
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following summary, based upon current law, is a general discussion of
certain federal income tax consequences of the Merger to the holders of Sense8
Stock, assuming the Merger is consummated as contemplated herein. This summary
is based upon the Code, applicable regulations promulgated under the Code by the
Treasury Department ("Treasury Regulations"), administrative rulings and
judicial authority as of the date hereof, all of which are subject to change,
possibly with retroactive effect. Any such change could affect the continuing
validity of this summary.
 
     This summary applies to holders of Sense8 Stock who hold their Sense8 Stock
as a capital asset. This summary does not discuss all aspects of federal income
taxation that may be relevant to a particular holder of Sense8 Stock in light of
the holder's specific circumstances or to certain types of holders subject to
special treatment under federal income tax laws (including, for example, foreign
persons, dealers in securities, holders who acquired Sense8 Stock pursuant to
the exercise of options or warrants or otherwise as compensation, banks and
other financial institutions, insurance companies, tax exempt organizations or
persons subject to the alternative minimum tax) and it does not discuss any
aspect of state, local foreign or other tax laws. Nor does this discussion
address tax consequences to the holders of other Sense8 securities (e.g.,
holders of Sense8 Warrants, Sense8 Options or debt securities).
 
     No ruling is being sought from the Internal Revenue Service as to the
anticipated tax consequences of the Merger. Further, this summary is not binding
on the Internal Revenue Service, and the Internal Revenue Service will not be
precluded from asserting contrary positions. CONSEQUENTLY, HOLDERS OF SENSE8
STOCK SHOULD CONSULT THEIR TAX ADVISORS AS TO THE TAX CONSEQUENCES TO THEM OF
THE MERGER, INCLUDING THE APPLICABILITY OF FEDERAL, STATE, LOCAL AND FOREIGN
INCOME AND OTHER TAX LAWS.
 
     The Merger.  It is a condition to consummation of the Merger that the
opinion addressed to Sense8 and the shareholders of Sense8 from Brobeck, Phleger
& Harrison LLP, counsel to Sense8, that the Merger will constitute, for federal
income tax purposes, a reorganization within the meaning of Section 368(a) of
the Code shall not have been amended, modified or withdrawn. The opinion of
Brobeck, Phleger & Harrison LLP is based upon the truth and accuracy of certain
assumptions and certain representations made to such counsel by EAI and Sense8
that are customarily made in connection with such an opinion.
 
     Among other assumptions or representations underlying the opinion regarding
the status of the Merger as a reorganization for federal tax purposes are
assumptions or representations (a) that following the Merger the historic
business of Sense8 will be continued or a significant portion of Sense8's assets
will be used in a trade or business; and, (b) that neither EAI nor any related
party will purchase any of the EAI Common Stock issued in the Merger.
 
                                       24
<PAGE>   32
 
     Assuming that the Merger constitutes a "reorganization" for United States
federal income tax purposes, the Merger will result in the following general
federal income tax consequences to the Sense8 shareholders:
 
          1. No gain or loss will be recognized by holders of Sense8 Stock upon
     the surrender of shares of Sense8 Stock and the receipt of shares of EAI
     Common Stock, except with respect to any cash received by a holder of
     Sense8 Stock in lieu of fractional shares of EAI Common Stock.
 
          2. A holder of Sense8 Stock who receives cash in lieu of fractional
     shares of EAI Common Stock in the Merger generally will be treated as if
     such holder received such fractional share which was subsequently redeemed,
     resulting in the cash such holder receives in lieu of such fractional share
     interest being treated as having been received as full payment in exchange
     for stock redeemed as provided in Section 302 of the Code.
 
          3. Each holder's aggregate tax basis in the EAI Common Stock received
     in the Merger will equal such holder's aggregate tax basis in the Sense8
     Stock surrendered, decreased by the amount of any tax basis allocable to
     any fractional share interest for which cash is received.
 
          4. The holding period of EAI Common Stock received in the Merger will
     include the holding period of the Sense8 Stock surrendered, provided that
     the Sense8 Stock is held as a capital asset in the hands of the holder
     thereof at the Effective Time of the Merger.
 
     As noted above, no ruling is being requested from the Internal Revenue
Service in connection with the Merger, and the opinion furnished by Brobeck,
Phleger & Harrison LLP as a condition to consummation of the Merger and the
discussion herein pertaining to the anticipated tax consequences associated with
the Merger will neither be binding on the Internal Revenue Service nor preclude
it from asserting contrary positions. Additionally, if any assumption or
representation that forms the basis for the opinion referred to above does not
conform to the facts associated with the Merger or if EAI takes actions
inconsistent with its representations after the Merger, the validity of the
opinion of Brobeck, Phleger & Harrison LLP and the discussion contained herein
could be adversely affected and could not be relied upon. A successful challenge
by the Internal Revenue Service to the status of the Merger as a reorganization
under Section 368(a) of the Code under any circumstances would result in each
holder of Sense8 Stock recognizing taxable income or loss with respect to the
shares of Sense8 Stock surrendered equal to the difference between the holder's
tax basis in such shares and the fair market value, as of the Effective Time of
the Merger, of the shares of EAI Common Stock and the cash received in the
Merger. In such event, a shareholder's aggregate basis in the shares of EAI
Common Stock received in the Merger would equal its fair market value and the
holding period for such shares would begin the day after the Merger.
 
     Reporting Requirements.  Holders of Sense8 Stock will be required to attach
a statement to their tax returns for the taxable year in which the Merger is
consummated that contains the information set forth in Treasury Regulations
Section 1.368-3(b). The statement must include the holder's tax basis in the
Sense8 Stock surrendered and a description of the EAI Common Stock received in
the Merger.
 
     THE DISCUSSION OF FEDERAL INCOME TAX CONSEQUENCES SET FORTH ABOVE IS FOR
GENERAL INFORMATION ONLY AND IS BASED ON EXISTING LAW AS OF THE DATE OF THIS
REGISTRATION STATEMENT. HOLDERS OF SENSE8 STOCK ARE URGED TO CONSULT THEIR TAX
ADVISORS TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE MERGER
(INCLUDING THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL, FOREIGN AND
OTHER TAX LAWS).
 
ACCOUNTING TREATMENT
 
     EAI and Sense8 intend that the Merger be accounted for as a "purchase" for
accounting and financial reporting purposes. Purchase accounting requires the
acquiror to determine the purchase price based on the consideration paid in the
acquisition. The fair value of the acquired net tangible assets is recorded by
the acquiror as of the date on which the acquisition is consummated. The excess
of purchase price over net tangible assets acquired is required to be allocated
among identifiable intangible assets. These identifiable intangible assets may
include, among other things, incomplete technology, complete technology, brands
and
                                       25
<PAGE>   33
 
trademarks, customer lists, employment contracts and copyrights. Any excess
purchase price over the acquired net tangible assets that is not allocated to
identifiable intangible assets is classified as goodwill. The amounts recorded
for intangible assets and goodwill are required to be amortized by systematic
charges to income over the estimated period of benefit and estimated useful
life.
 
REGULATORY APPROVALS
 
     EAI and Sense8 are aware of no governmental or regulatory approvals
required for consummation of the Merger, other than compliance with applicable
securities and "blue sky" laws.
 
DISSENTERS' RIGHTS
 
     The CGCL entitles any shareholder of Sense8 to dissent from the Merger and
obtain payment in cash for the "fair market value" of his or her Sense8 Stock,
instead of receiving the shares of EAI Common Stock to which he or she would
otherwise be entitled pursuant to the Merger Agreement. To exercise such
dissenters' rights, shareholders of Sense8 must comply with the procedural
requirements of the CGCL, a summary of which is provided below.
 
     Under the CGCL, a shareholder of Sense8 may dissent from the Merger and
obtain the fair market value of the shares owned by such shareholder with such
fair market value to be paid in cash if the Merger is consummated. Under the
CGCL, "fair market value" is determined as of the day before the first
announcement of the terms of the proposed reorganization, excluding any
appreciation or depreciation in consequence of the proposed action, but adjusted
for any stock split, reverse stock split or share dividend which becomes
effective thereafter.
 
     Any shareholder of Sense8 who wishes to assert his or her dissenters'
rights must do each of the following: (i) deliver to Sense8 before the vote on
the Merger Agreement is taken a written notice of such shareholder's intent to
demand payment of the fair market value of his or her shares if the Merger is
effectuated, and (ii) not vote such shares in favor of the approval of the
Merger Agreement at the Meeting. A VOTE AGAINST THE APPROVAL OF THE MERGER
AGREEMENT WILL NOT, BY ITSELF, BE REGARDED AS A WRITTEN NOTICE OF A
SHAREHOLDER'S INTENT TO ASSERT DISSENTERS' RIGHTS.
 
     If the Merger Agreement is approved at the Meeting, Sense8 shall deliver a
written notice (the "Dissenters' Notice") to each person who asserted
dissenters' rights and who did not vote in favor of the approval of the Merger
Agreement as described above. The Dissenters' Notice must be sent by Sense8 no
later than 10 days after the Meeting and must contain the following information:
(i) a notice of the approval of the Merger Agreement by its outstanding shares;
(ii) a statement of the price determined by Sense8 to represent the fair market
value of the dissenting shares; (iii) a brief description of the procedure to be
followed if the shareholder desires to exercise the shareholder's right; and
(iv) a copy of Sections 1300 through 1304 of the CGCL. The statement of price by
Sense8 constitutes an offer by Sense8 to purchase any Dissenting Shares at the
stated amount.
 
     Within 30 days after the date in which the Dissenters' Notice is mailed to
such shareholder, a dissenting shareholder must mail or deliver the written
demand to Sense8 stating that such shareholder is demanding purchase of his or
her shares of Sense8 Stock, stating the number of shares that Sense8 must
purchase, what the shareholder claims to be the fair market value of such shares
and enclosing the Certificates for endorsement. A shareholder who does not
demand payment or deposit certificates for shares by the date or in the manner
set forth in the Dissenters' Notice will be deemed to have waived his or her
dissenters' rights and will not be entitled to payment of the fair value of his
or her shares under Chapter 13 of the CGCL.
 
     If Sense8 and the dissenting shareholder agree on the fair market value of
the dissenting shares, Sense8 must make a cash payment to the dissenting
shareholder who files a demand for payment as described above equal to the
agreed upon fair market value of the shares of Sense8 Stock owned by such
shareholder, plus accrued interest on such payment at the legal rate on
judgments from the date of the agreement. Such
 
                                       26
<PAGE>   34
 
payment must be made within thirty days of the later of: (i) the date of the
agreement on fair market value of the Dissenting Shares, or (ii) the date all
statutory or contractual conditions to the Merger are satisfied.
 
     If Sense8 denies that the shares are Dissenting Shares, or if Sense8 and
the shareholder fail to agree on the fair market value of the shares, then the
shareholder may file a complaint requesting a determination of the fair market
value of the Dissenting Shares in California superior court of the proper county
within six months after the date on which the Dissenters' Notice was mailed. The
court will determine the issues and may appoint an appraiser to determine the
fair market value of the shares. The costs of the action, including reasonable
compensation to any appraisers, shall be assessed or apportioned as the court
considers equitable.
 
     Shareholders who receive cash for their shares of Sense8 Stock upon
exercise of dissenters' rights will realize taxable gain or loss.
 
     THE PRECEDING DISCUSSION IS A SUMMARY OF THE PROVISIONS REGARDING
DISSENTERS' RIGHTS UNDER THE CGCL AND IS QUALIFIED IN ITS ENTIRETY BY THE TEXT
OF CHAPTER 13 OF THE CGCL OF WHICH SECTION 1300 THROUGH 1304 ARE ATTACHED AS
APPENDIX B TO THIS PROXY STATEMENT/PROSPECTUS. SENSE8 SHAREHOLDERS WHO ARE
INTERESTED IN ASSERTING DISSENTERS' RIGHTS PURSUANT TO THE CGCL IN CONNECTION
WITH THE MERGER MAY WISH TO CONSULT WITH THEIR COUNSEL FOR ADVICE AS TO THE
PROCEDURES REQUIRED TO BE FOLLOWED.
 
RESALE OF EAI COMMON STOCK ISSUED IN THE MERGER; AFFILIATES
 
     The EAI Common Stock to be issued to Sense8 shareholders in connection with
the Merger will be freely transferable under the Securities Act, except for EAI
Common Stock issued to any person deemed to be an affiliate of Sense8 for
purposes of Rule 145 under the Securities Act ("Rule 145"). Affiliates may not
sell their EAI Common Stock acquired in connection with the Merger except
pursuant to an effective registration statement under the Securities Act
covering such shares, or in compliance with Rule 145 or another applicable
exemption from the registration requirements of the Securities Act.
 
                          INTERIM MANAGEMENT AGREEMENT
 
     In connection with the Merger Agreement, Sense8 and EAI entered into an
Interim Management Agreement (the "Management Agreement"). The Management
Agreement provides for the joint management of Sense8 by EAI and Sense8 during
the period (the "Interim Period") from April 11, 1998 through the date of the
consummation of the Merger. Under the Management Agreement, Thomas Coull
resigned on April 11, 1998 as Chief Executive Officer of Sense8 and retained the
title of President of Sense8. The Executive Vice President of EAI, Martin J.
Vanderploeg, Ph.D., began serving as Chief Executive Officer of Sense8 on such
date and reports to the Board of Directors of Sense8. The Management Agreement
provides that Sense8 shall reimburse EAI for the costs incurred in making EAI's
employees, other than Dr. Vanderploeg, available to Sense8 during the Interim
Period, and Sense8 shall indemnify all EAI employees who render services to
Sense8 during the Interim Period from and against any claims or liabilities
relating to their services to Sense8.

INDUSTRY BACKGROUND
 
     Until 1980, interactive 3D graphics was limited to specialized
applications, such as flight simulators, and relied on expensive dedicated
systems incorporating custom software running on real-time computers. The
availability of interactive 3D graphics was significantly expanded during the
1980s with the introduction of high performance Unix workstations incorporating
3D graphic processors, designed for a variety of specialized technical and
business applications. Since the 1980s, the ability of 3D workstations to create
and manipulate complex 3D objects in real-time has given scientists, engineers
and creative professionals significant productivity advantages in applications
such as 3D modeling, simulation, scientific visualization and animation.
 
     The use of 3D graphics workstations and related software applications had
been largely confined to the limited market of sophisticated professional users
due to the high cost of these workstations and related software, as well as the
relative difficulty of learning and using Unix and Unix-based applications.
However, the recent proliferation of high performance microprocessors such as
the Pentium II and Pentium Pro, the increased adoption of the Windows NT and
Windows 95 operating systems with the embedded 3D graphics APIs, OpenGL and
Direct 3D, and the introduction of a new generation of cost effective, 3D
graphics processors have begun to allow interactive 3D graphics technology to be
more widely available.
 
     The recent advancements in affordable 3D graphics have encouraged corporate
customers to consider interactive 3D graphics and virtual reality technology for
their training, simulation, entertainment and marketing needs. The customers in
these markets are generally application developers rather than application
buyers, thus they represent a viable market for Sense8's tools.
 
PRODUCTS AND SERVICES
 
     Sense8 designs its products around an "OpenVR" philosophy. As such, all of
Sense8's products enable customers to build applications that run across
hardware platforms, graphic systems and input/output devices. Sense8's tools are
sophisticated and offer complete functionality for the development of 3D objects
with complex behaviors. Sense8's products are inherently open to a variety of
information sources such as relational database and file formats from 3D
modeling and CAD programs.

Comparison of 1997 to 1996
 
     Net Revenues.  Sense8 net revenues include product licenses, consulting and
support services, and third-party product sales. These revenues are net of
discounts given to resellers. Product license revenues and third party product
revenues are recognized upon shipment to customers or to resellers. Revenues
from product support agreements are deferred over the period of 12 months
following the license sale to the end user customer. Consulting services are
recognized on a percent of contract completion basis.
 
     Net revenues for 1997 decreased 43% to $4.0 million from $7.0 million in
1996. This decrease resulted from a company decision to decrease low margin
third party product sales and from a general weakening in the virtual reality
consulting and product market. This market change combined with an overall
weakening in the Asian markets caused Sense8's largest reseller to decrease
inventory levels rather than order products from Sense8.
 
     Cost of Net Revenues.  Sense8 cost of net revenues includes cost of third
party items for resale, labor and material expenses for consulting services
performed, salaries for technical support services, and physical media,
documentation and packing costs for software products. Cost of net revenues for
1997 decreased 47% to $1.1 million from $2.0 million in 1996. This decrease was
due primarily to the reduction in third party products purchased for resale.
 
                                       33
<PAGE>   41
 
     Sales and Marketing Expenses.  Sales and marketing expenses include
personnel costs, travel, collateral, direct mail, trade shows, public relations
and other sales and marketing costs. Sales and marketing expenses for 1997
decreased 39% to $1.9 million from $3.1 million in 1996. This decrease was due
primarily to a reduction in U.S. sales and marketing personnel costs and related
travel expenses, the closing of Sense8 SA, Sense8's Swiss sales and marketing
subsidiary, and a reduction in marketing expenses including public relations and
trade shows.
 
     General and Administrative Expenses.  General and administrative expenses
consist primarily of salaries and facilities costs for executive,
administrative, accounting and product production personnel, as well as
benefits, reserve for bad debt, equipment rental, telephone, and consultant and
professional fees. General and administrative expenses for 1997 decreased 13% to
$1.4 million from $1.6 million in 1996. This decrease was due primarily to a
reduction in executive compensation, closing Sense8 SA and a reduction in
facilities costs. The decrease was partially offset by an increase in consulting
and professional fees.
 
     Research and Development Expenses.  Sense8 expenses all research and
development costs. These expenses consist primarily of salaries and facilities
for software development personnel, consulting fees, equipment, and other
miscellaneous expenses. Research and development expenses for 1997 decreased 27%
to $1.1 million from $1.5 million in 1996. This decrease was due primarily to a
reduction in consulting fees, salaries of senior managers and development
personnel costs.
 
     Income Tax Expense.  The effective tax rate for the years ended December
31, 1997 and 1996 was zero percent. The differences between Sense8's effective
tax rate for the years ended December 31, 1997 and 1996 and the U.S. federal
statutory tax rate of 34% result primarily from losses from operations as well
as tax credits and permanent differences.
 
Comparison of 1996 to 1995
 
     Net Revenues.  Net revenues for 1996 increased 20% to $7.0 million from
$5.8 million in 1995. This increase was the net effect of increasing software
license sales (98%) and decreasing sales from third party products (41%) in 1996
from 1995. This significant increase in software license sales was the result of
increased investment into sales and marketing. Sense8 had several large license
sales in 1996, including a one-time license to one customer for $678,000 and a
$225,000 distribution license to another customer. From 1995 to 1996, product
orders from Sense8's Japanese reseller increased approximately 100%. The
decrease in sales from third party product was due to a management decision to
focus the company's sales and marketing activities less on third party products
in favor of software licenses.
 
     Cost of Net Revenues.  Cost of net revenues for 1996 decreased 8% to $2.0
million from $2.2 million in 1995. This decrease was the net of a reduction in
third party products purchased for resale and an increase in consulting and
support expenses. This increase was due primarily to project management,
engineering and artistic staff added to Sense8's consulting services group.
 
     Sales and Marketing Expenses.  Sales and marketing expenses for 1996
increased 136% to $3.1 million from $1.3 million in 1995. Sense8 invested
significantly in sales and marketing in 1996. The increase in sales and
marketing expenses was largely due to an increase in sales and marketing
personnel costs, as well as larger trade show, direct mail, advertising and
public relations expenses. Sense8 opened and staffed two sales offices in 1996,
Sense8 SA in Nyon, Switzerland and an east-coast office in Bethesda, Maryland.
 
     General and Administrative Expenses.  General and administrative expenses
for 1996 increased 73% to $1.6 million from $0.9 million in 1995. This increase
was due primarily to the administrative and executive personnel costs added to
support the new offices in Nyon and Bethesda, increases in executive
compensation, travel, benefits, telephone and other expenses.
 
     Research and Development.  In the first half of 1996, Sense8 invested
significantly in the development of World Up Release 3. This development
resulted in increased consulting expenses for documentation and quality
assurance. Research and development expenses for 1996 increased 44% to $1.5
million from $1.1 million in 1995. This increase was also the result of
engineering, product management and documentation personnel expenses added in
early 1996.
                                       34
<PAGE>   42
 
     Income Tax Expense.  The effective tax rate for the years ended December
31, 1996 and 1995, was zero percent and 22 percent, respectively. The
differences between Sense8's effective tax rate for the years ended December 31,
1996 and 1995 and the U.S. federal statutory tax rate of 34% resulted primarily
from 1996 losses from operations as well as tax credits and permanent
differences during the years ended December 31, 1996 and 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Sense8 financed its operations through internally generated cash flow, a
private placement of equity in 1996, and debt financing in 1995 and 1997. Cash
and cash equivalents were $95,000, $167,000 and $57,000 at December 31, 1995,
1996 and 1997, respectively.
 
     Net cash used by operating activities for the year ended December 31, 1997
was $697,000. Net cash used by operating activities for the year ended December
31, 1996 was $771,000. Net cash provided by operating activities for the year
ended December 31, 1995 was $187,000.
 
     Sense8's LINC Capital loan is secured by Sense8's equipment and office
workstation assets. As of December 31, 1997, $182,600 in principal was
outstanding under such loan at an interest rate of 17.43%. The loan becomes due
and payable monthly with a $30,000 balloon payment due on May 1, 2001.
 
     On March 24, 1998, Sense8 executed a demand promissory note in favor of EAI
(the "Note") under which Sense8 has borrowed $375,000 as of April 30, 1998 in
order to address Sense8's immediate cash flow requirements. The outstanding
principal under the Note plus interest, accruing at a rate of 7%, must be repaid
by Sense8 within 60 days following EAI's demand for repayment. If EAI were to
make such a demand, Sense8 does not believe it will have the capital resources
necessary to fulfill its obligations to EAI. No assurance can be given that
additional funds will be available from EAI.
 
     On March 27, 1998, Sense8 and EAI entered into a Master Reseller Agreement
under which Sense8 provided EAI with approximately $210,000 of Sense8 software
products in March 1998, for which EAI will only be obligated to pay $125,000 in
exchange for an increase in the Total Merger Consideration by $260,000. The
reduced revenue under the Master Reseller Agreement has negatively impacted
Sense8's revenue and cash flow in March and April and will continue to have a
negative impact in May 1998.
 
     In addition, as a result of the management direction provided by EAI under
the Interim Management Agreement, Sense8's consulting services have been
utilized by EAI exclusively and Sense8 has not received, nor does it expect to
receive, any revenue from the provision of such services. This has had a
negative impact on Sense8's revenue and cash flow as its consulting services
account for approximately 20% of its quarterly revenue.
 
CERTAIN TRANSACTIONS
 
     On June 26, 1997, Patrice Gelband, a Sense8 director, Thomas B. Coull, a
Sense8 director and President, and E&S, a major shareholder of Sense8, purchased
Sense8 Convertible Notes (the "Series B Notes") in the principal amount of
$42,000, $42,000 and $150,000, respectively. Such notes bear interest at a rate
of 12%, payable quarterly in arrears. The principal amount of such notes and
accrued interest becomes due and payable July 11, 2000. The Series B Notes may
be converted at the option of the holder into shares of Sense8 Series B
Preferred with a conversion price of $17.00 per share. In addition, as part of
the same transaction on June 26, 1997, warrants to purchase 2,470, 2,470 and
8,824, respectively, shares of Sense8 Series B Preferred (the "Series B
Warrants") with an exercise price of $17.00 per share were issued to Ms.
Gelband, Mr. Coull and E&S. The aggregate purchase price paid by Ms. Gelband,
Mr. Coull and E&S for the Series B Notes and Series B Warrants held by each such
investor was $42,000, $42,000 and $150,000, respectively.
 
     On February 26, 1998, Sense8 entered into a binding letter of intent with
E&S (the "LOI"), providing for a loan to Sense8 of $125,000 on such date. The
LOI also gave E&S a variety of rights, including, without limitation, a right of
first refusal (the "Right of First Refusal") in favor of E&S to match any offers
to purchase Sense8 received through April 20, 1998 and an option (the "Option")
to acquire Sense8 for the period commencing April 21, 1998 through May 31, 1998
for a purchase price of $2,750,000.
                                       35
<PAGE>   43
 
     In accordance with the terms of the LOI, on March 27, 1998, Sense8 entered
into a Series A Preferred Stock Purchase Agreement with E&S (the "Series A
Financing") whereby E&S purchased from Sense8 220,694 shares of Sense8 Series A
Preferred in exchange for the cancellation of the convertible promissory note
executed by Sense8 in favor of E&S dated February 26, 1998 in the principal
amount of $125,000 and the cancellation of 70,782 shares of Sense8 Series B
Preferred held by E&S. In connection with this transaction, E&S agreed to amend
the terms of its Series B Note and a certain Series B Warrant Agreement dated
June 26, 1997 to reduce the conversion price of each of the Series B Note and
Series B Warrant from $17.00 to $6.80 per share and change the underlying
securities of each of the Series B Note and Series B Warrant from Sense8 Series
B Preferred to Sense8 Series A Preferred. Sense8 also agreed to perform certain
engineering services for E&S and granted E&S a credit towards the fees of such
engineering services in the amount of $125,000.
 
     As of the date hereof, the Series B Notes held by Ms. Gelband and Mr. Coull
are each convertible into 2,685 shares of Sense8 Series B Preferred and the
Series B note held by E&S is convertible into 8,824 shares of Sense8 Series A
Preferred.
 
     Also on March 27, 1988, an Option Agreement was executed by Sense8, E&S and
the shareholders of Sense8 listed on Schedule A thereto, providing for the Right
of First Refusal and the Option to acquire Sense8 substantially in accordance
with the LOI (the "Acquisition Transaction"). Thomas B. Coull, Patrice Gelband,
Intel Corporation and E&S signed on March 27, 1998 a Stockholders Voting
Agreement and Irrevocable Proxy agreeing to vote to approve the Acquisition
Transaction.
 
     In addition, Sense8 has an ongoing business relationship with two of its
major shareholders, Intel Corporation and E&S, whereby Sense8 supplies Intel and
E&S with custom-built software applications. Sense8 had a total of three
material (e.g., in excess of $60,000) purchase orders from these shareholders:
one from E&S dated October 1, 1997 for $69,000 and two from Intel dated
September 1, 1997 and May 1, 1997 for $68,000 and $63,000, respectively. These
purchase orders were satisfied prior to December 31, 1997.

               RIGHTS OF EAI STOCKHOLDERS AND SENSE8 SHAREHOLDERS
 
DESCRIPTION OF EAI STOCK
 
     The authorized capital stock of EAI consists of 20,000,000 shares of EAI
Common Stock, $.01 par value, and 20,000,000 shares of Preferred Stock, $.01 par
value (the "EAI Preferred Stock"). The stockholders of EAI approved an amendment
to EAI's Certificate of Incorporation at EAI's annual meeting of stockholders on
May 1, 1998. This amendment, when filed with the Secretary of State of Delaware,
will increase the number of shares of authorized EAI Common Stock from
20,000,000 to 60,000,000. As of April 30, 1998, there were 10,209,950 shares of
EAI Common Stock outstanding and no shares of Preferred Stock outstanding. As of
April 30, 1998, there were 557 holders of record of EAI Common Stock. The EAI
Common Stock is listed and traded on the NNM under the symbol "EAII."
 
COMMON STOCK
 
     The holders of EAI Common Stock are entitled to one vote for each share
held of record on all matters voted upon by stockholders and may not use
cumulative voting for the election of directors. Thus, the owners of a majority
of the EAI Common Stock outstanding are able to elect all of the directors. Each
outstanding share of EAI Common Stock is entitled to participate equally in any
distribution of net assets made to the stockholders in liquidation, dissolution
or winding up of EAI and is entitled to participate equally in dividends and
other distributions, if, as and when declared by the Board of Directors. There
are no redemption, sinking fund, conversion or preemptive rights with respect to
the EAI Common Stock. All shares of EAI Common Stock have equal rights and
preferences.
 
EAI PREFERRED STOCK
 
     Pursuant to EAI's Certificate of Incorporation (the "EAI Certificate"), EAI
is authorized to issue up to 20,000,000 shares of EAI Preferred Stock, which may
be issued from time to time in one or more series upon authorization by EAI's
Board of Directors. EAI's Board of Directors, without further approval of the
stockholders, is authorized to fix the number of shares constituting any series,
dividend rights and terms, conversion rights and terms, voting rights and terms,
redemption rights and terms, liquidation preferences and any other rights,
preferences, privileges and restrictions applicable to each series of the EAI
Preferred Stock. The issuance of the EAI Preferred Stock, while providing
flexibility in connection with possible acquisitions and other corporate
purposes could, among other things, adversely affect the voting power of the
holders of the EAI Common Stock and, under certain circumstances, have the
effect of making it more difficult for a third party to acquire, or discouraging
a third party from acquiring, a majority of the outstanding voting stock of EAI,
or otherwise adversely affect the market price of the EAI Common Stock. EAI is
not aware of any plans by a third party to seek control of EAI. EAI has no
current plans to issue any EAI Preferred Stock.
 
RIGHTS
 
     EAI has adopted a Stockholders Rights Plan. Under the Stockholders Rights
Plan, each share of EAI Common Stock has associated with it one preferred share
purchase right (a "Right"). The terms of the Rights are set forth in a Rights
Agreement. Under certain circumstances described below, each Right would entitle
the holders thereof to purchase one one-hundred-and fiftieth of a share of
Series A Junior Participating Preferred Stock of EAI for a price of $50.00 per
one one-hundred-and fiftieth of a share. The Rights are not currently
exercisable when issued and are transferable only with the related shares of EAI
Common Stock.
 
     The Rights would become exercisable at the specified exercise price upon
the earlier to occur of (i) 10 business days after the first public announcement
that any person or group (other than an Exempt Person)
 
                                       39
<PAGE>   47
 
(an "Acquiring Person") has acquired beneficial ownership of 15% or more of the
outstanding shares of EAI Common Stock and (ii) 10 business days (unless delayed
by EAI's Board of Directors) after any person or group (other than an Exempt
Person) has commenced, or announced the intention to commence, a tender or
exchange offer that would, upon its consummation, result in such person or group
being the beneficial owner of 15% or more of the outstanding shares of EAI
Common Stock (each a "Triggering Event"). Rights will not be exercisable
following the occurrence of an event described below under the caption "Flip-in"
prior to the expiration of EAI's right to redeem the Rights. Rights certificates
will be distributed when the Rights become exercisable. An "Exempt Person" will
include EAI and certain related entities.
 
     Flip-in.  After the Rights become exercisable (unless the Triggering Event
is the commencement or the announcement of a tender or exchange offer as
described in (ii) in the immediately preceding paragraph), the holders of the
Rights (other than an Acquiring Person and certain transferees thereof) would be
entitled to exercise the Rights to purchase that number of shares of EAI Common
Stock which at the time of such acquisition would have a market value of two
times the exercise price of the Rights. After the occurrence of a Flip-in event,
the Rights of an Acquiring Person and such transferees will become void.
 
     Flip-over.  In the event that, on or after the date on which an Acquiring
Person has become such: (i) EAI merges into or consolidates with an Interested
Stockholder or, unless all holders of the outstanding shares of EAI Common Stock
are treated the same, any other person (with limited designated exceptions),
(ii) an Interested Stockholder or, unless all holders of the outstanding shares
of EAI Common Stock are treated the same, any other person (with limited
designated exceptions) merges into EAI or (iii) EAI sells or transfers 50% or
more of its consolidated assets or earning power to an Interested Stockholder
or, unless all holders of the outstanding shares of EAI Common Stock are treated
the same, any other person (with limited designated exceptions), the holders of
the Rights (other than Rights which have become void) would be entitled to
purchase common shares of the acquirer (or a person affiliated therewith) at a
50% discount. In general, an "Interested Stockholder" will be an Acquiring
Person and certain persons affiliated, associated or acting on behalf of or in
concert therewith.
 
     Redemption of Rights.  The Rights are redeemable, as a whole, at a
redemption price of $.01 per Right, subject to adjustment, at the direction of
EAI's Board of Directors, at any time prior to the acquisition by a person or
group of beneficial ownership of 15% or more of the outstanding shares of EAI
Common Stock.
 
     Exchange of Shares for Rights.  At any time after any person or group shall
have become an Acquiring Person and before any person (other than an Exempt
Person), together with its affiliates and associates, shall have become the
beneficial owner of 50% or more of the outstanding shares of EAI Common Stock,
EAI's Board of Directors has the right to direct the exchange of shares of EAI
Common Stock for all or any part of the Rights (other than Rights that have
become void) at the exchange rate of one share of EAI Common Stock per Right,
subject to adjustment.
 
     EAI's Rights Agreement may discriminate against a prospective holder of EAI
Common Stock as a result of such holder owning a substantial amount of shares
and may have the effect of delaying, deferring or preventing a change in control
of EAI. See "-- Comparison of Rights of EAI Stockholders and Sense8
Shareholders -- Rights Plan."
 
DESCRIPTION OF SENSE8 CAPITAL STOCK
 
     The authorized capital stock of Sense8 consists of 10,000,000 shares of
Sense8 Common Stock, $.001 par value, and 5,000,000 shares of Sense8 Preferred
Stock, $.001 par value, 350,585 shares of which are designated as Sense8 Series
A Preferred and 146,326 shares of which are designated as Sense8 Series B
Preferred. As of April 11, 1998, there were 828,693 shares of Sense8 Common
Stock issued and outstanding and held of record by 16 shareholders, 308,929
shares of Sense8 Series A Preferred issued and outstanding and held of record by
two shareholders and no shares of Sense8 Series B Preferred were issued and
outstanding.

SENSE8 COMMON STOCK
 
     Holders of Sense8 Common Stock are entitled to receive dividends when
declared by the Board of Directors. Holders of Sense8 Common Stock have no
preemptive rights, no right to convert Sense8 Common Stock into any other
securities and no redemption rights. All outstanding shares of the Sense8 Common
Stock are validly issued, fully paid and nonassessable.
 
SENSE8 PREFERRED STOCK
 
     The principal rights, privileges and preferences of the issued and
outstanding shares of Sense8 Preferred Stock are as set forth below.
 
Dividends
 
     Dividends accrue only when declared by the Board of Directors, at the rate
of (i) $0.68 per share of Sense8 Series A Preferred and (ii) $1.77 per share of
Sense8 Series B Preferred (each series adjusted for subsequent stock dividends,
stock splits, or recapitalization). Such dividends are not cumulative.
 
     If cash dividends are declared, then holders of Sense8 Preferred Stock are
entitled to cash dividends as distributed among the holders of Sense8 Series A
Preferred and Sense8 Series B Preferred pro rata based upon the dividend
preference of each series. Dividends on Sense8 Common Stock are paid only after
the Sense8 Preferred Stock dividends have been paid.
 
     If dividends payable in assets other than cash are declared, then holders
of Sense8 Preferred Stock are entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Sense8
Common Stock into which their shares of Sense8 Preferred Stock are convertible.
The conversion price of the affected Sense8 Preferred Stock series shall be
appropriately decreased so that the number of shares of Sense8 Common Stock
issuable on conversion of each share of such series shall be increased in
proportion to such increase in the aggregate of shares of Sense8 Common Stock
outstanding.
 
Liquidation
 
     (a) Liquidation Preference.  In the event of any liquidation, dissolution
or winding up of Sense8 (which, as defined in Sense8's Articles of
Incorporation, would include the Merger) holders of the Sense8 Series A
Preferred and Sense8 Series B Preferred are entitled to receive, prior and in
preference to any distribution of any assets of Sense8 to the holders of Sense8
Common Stock, $6.80 and $17.66 per share, respectively, plus all declared but
unpaid dividends. After the holders of Sense8 Preferred Stock have received the
full amount of their liquidation preference, the holders of Sense8 Common Stock
and Sense8 Preferred Stock are entitled to receive all remaining assets of
Sense8 available for distribution, pro rata based on the number of shares of
Sense8 Common Stock held by each (assuming conversion of all shares of Series A
Preferred and Sense8 Series B Preferred into Sense8 Common Stock) until Sense8
Series A Preferred and Sense8 Series B Preferred shareholders have received an
aggregate amount of $27.20 and $38.06 (including amounts paid pursuant to the
previous sentence), respectively; thereafter holders of Sense8 Common Stock
receive all of the remaining assets of Sense8 pro rata based on the number of
shares of Sense8 Common Stock held by each.
 
     (b) Determination of Value.  If the consideration received is other than
cash, the value of such securities shall be valued as follows:
 
          (1) Securities not subject to investment letter or other similar
     restrictions on free marketability:
 
             (i) If traded on a securities exchange or through The Nasdaq Stock
        Market National Market, the value shall be deemed to be the average of
        the closing prices of the securities on such exchange over the
        thirty-day period ending three (3) days prior to the closing; provided,
        however, with respect to the Merger Agreement, the value of EAI's
        securities for the purposes of the foregoing shall be deemed to be
        $42.61725.
 
                                       41
<PAGE>   49
 
             (ii) If actively traded over-the-counter, the value shall be deemed
        to be the average of the closing bid or sale prices (whichever is
        applicable) over the thirty-day period ending three (3) days prior to
        the closing.
 
             (iii) If there is no active public market, the value shall be the
        fair market value thereof, as mutually determined by Sense8 and the
        holders of a majority of Sense8 Series A Preferred and Sense8 Series B
        Preferred, voting together as one class.
 
          (2) The method of valuation of securities subject to investment letter
     or other restrictions on free marketability (other than restrictions
     arising solely by virtue of a shareholder's status as an affiliate or
     former affiliate) shall be to make an appropriate discount from the market
     value determined as above in clauses (i), (ii) and (iii) to reflect the
     approximate fair market value thereof, as mutually determined by Sense8 and
     the holders of a majority of the voting power of all then outstanding
     shares of Sense8 Series A Preferred and Sense8 Series B Preferred, voting
     together as one class.
 
Redemption
 
     The Sense8 Series A Preferred and Sense8 Series B Preferred are not
redeemable.
 
Conversion
 
     Each share of the Sense8 Series A Preferred and Sense8 Series B Preferred
is presently convertible into shares of Sense8 Common Stock in the amount as
determined by dividing the respective Sense8 Preferred Stock series' original
issue price by the appropriate and applicable conversion price. The resulting
conversion amount is further subject to adjustment by anti-dilution provisions.
 
Voting Rights
 
     Subject to the protective provisions described below and except as
otherwise required by law, the holders of the Sense8 Series A Preferred, Sense8
Series B Preferred and Sense8 Common Stock are entitled to notice of any
shareholders' meeting and to vote together as one class upon any matter
submitted to the shareholders for a vote on the following basis:
 
     (a) Common Vote.  Each share of Sense8 Common Stock issued and outstanding
shall have one vote.
 
     (b) Preferred Vote.  Each holder of Sense8 Series A Preferred and Sense8
Series B Preferred shall have a number of votes equal to the number of shares of
Sense8 Common Stock into which such Sense8 Preferred Stock is convertible.
 
          (i) Board of Directors.  So long as at least 100,000 shares of Sense8
     Series A Preferred are outstanding, the holders of Sense8 Series A
     Preferred, voting as one class, shall be entitled to elect one member of
     the Board of Directors, and the holders of Sense8 Series A Preferred,
     Sense8 Series B Preferred and Sense8 Common Stock, voting on an
     as-converted basis as one class, shall be entitled to elect all other
     members of the Board of Directors. If less than 100,000 shares of Sense8
     Series A Preferred are outstanding, the Sense8 Series A Preferred, Sense8
     Series B Preferred and Sense8 Common Stock, voting as one class, shall be
     entitled to elect all directors. Any vacancy in the Board occurring because
     of the death, resignation or removal of a director elected by the holders
     of the outstanding class or series with voting power entitled to elect him
     or her shall be filled by the vote or written consent of the holders of the
     outstanding class or series with voting power entitled to elect him or her
     or, in the absence of action by such holders, by action of the remaining
     directors elected by such class or series. A director may be removed with
     or without cause by the vote or consent of the holders of the outstanding
     class or series with voting power entitled to elect him or her in
     accordance with the CGCL.
 
          (ii) All Other Matters.  On all other matters, the holder of each
     share of Sense8 Series A Preferred or Sense8 Series B Preferred shall have
     full voting rights and powers equal to the voting rights and powers of the
     holders of Sense8 Common Stock, except as required by law, and shall be
     entitled, notwithstanding any provision hereof, to notice of any
     shareholders' meeting in accordance with the bylaws of this
 
                                       42
<PAGE>   50
 
     corporation, and shall be entitled to vote, together with the holders of
     Sense8 Common Stock. Fractional votes shall not, however, be permitted and
     any fractional voting rights available on an as-converted basis (after
     aggregating all shares into which shares of Sense8 Series A Preferred and
     Sense8 Series B Preferred held by each holder could be converted) shall be
     rounded to the nearest whole number (with one-half rounded upward).
 
Protective Provisions
 
     (a) Sense8 Series A Preferred.  In addition to any other rights provided by
law or agreement, so long as any shares of Sense8 Series A Preferred are
outstanding, Sense8 may not, without first obtaining the affirmative vote or
written consent of the holders of a majority of the then outstanding shares of
Sense8 Series A Preferred:
 
          (i) alter or change the rights, preferences or privileges of the
     shares of Sense8 Series A Preferred so as to affect adversely the shares;
 
          (ii) increase or decrease (other than by redemption or conversion) the
     total number of authorized shares of Sense8 Series A Preferred;
 
          (iii) authorize or issue (including, without limitation, the
     reclassification of any outstanding shares) any other equity security
     having a preference over, or being on a parity with, the liquidation and
     dividend preferences of the Sense8 Series A Preferred; or
 
          (iv) declare or pay any dividends on or declare or make any other
     distributions, direct or indirect (other than a dividend payable solely in
     shares of Sense8 Common Stock or dividends declared prior to the purchase
     date applicable to the Sense8 Series A Preferred), on any shares of Sense8
     Common Stock, or set apart any sum for any such purpose.
 
     (b) Sense8 Series B Preferred.  In addition to any other rights provided by
law or agreement, so long as any shares of Sense8 Series B Preferred are
outstanding, Sense8 may not without first obtaining the affirmative vote or
written consent of the holders of a majority of the then outstanding shares of
Sense8 Series B Preferred:
 
          (i) alter or change the rights, preferences or privileges of the
     shares of Sense8 Series B Preferred so as to affect adversely the shares;
 
          (ii) increase or decrease (other than by redemption or conversion) the
     total number of authorized shares of Sense8 Series B Preferred;
 
          (iii) authorize or issue (including, without limitation, the
     reclassification of any outstanding shares) any other equity security
     having a preference over the liquidation and dividend preferences of the
     Sense8 Series B Preferred;
 
          (iv) authorize or issue (including, without limitation, the
     reclassification of any outstanding shares) any other equity security which
     votes together with the holders of Sense8 Common Stock on an as-converted
     basis and has the right to more than one vote for each share of Sense8
     Common Stock into which such equity security could then be converted; or
 
          (v) declare or pay any dividends on or declare or make any other
     distributions, direct or indirect (other than a dividend payable solely in
     shares of Sense8 Common Stock), on any shares of Sense8 Common Stock, or
     set apart any sum for any such purpose.
 
COMPARISON OF RIGHTS OF EAI STOCKHOLDERS AND SENSE8 SHAREHOLDERS
 
     EAI is incorporated under the laws of the State of Delaware and Sense8 is
incorporated under the laws of the State of California. The rights of the
holders of Sense8 Stock are currently governed by the CGCL, the Sense8 Articles
and Sense8's By-laws (the "Sense8 By-laws," together with the Sense8 Articles,
the "Sense8 Governing Documents"). If the Merger is consummated in accordance
with the terms of the Merger Agreement, Sense8 shareholders will become holders
of EAI Common Stock and their rights as such will be
                                       43
<PAGE>   51
 
governed by the Delaware General Corporation Law (the "DGCL"), the EAI
Certificate and EAI's By-laws (the "EAI By-laws," together with the EAI
Certificate, the "EAI Governing Documents"). Certain of the material differences
between the rights of holders of Sense8 Stock and the rights of holders of EAI
Common Stock are summarized below.
 
     The following summary is not a complete statement of the rights of holders
of EAI Common Stock under applicable Delaware laws or the EAI Governing
Documents, or a comprehensive comparison with the rights of the holders of
Sense8 Stock under applicable California laws or the Sense8 Governing Documents,
or a complete description of the specific provisions referred to herein. The
identification of specific differences is not meant to indicate that other
equally or more significant differences do not exist. This summary is qualified
in its entirety by reference to the DGCL, the CGCL, the EAI Governing Documents
and the Sense8 Governing Documents, to which holders of Sense8 Stock are
referred. For information as to how such documents may be obtained, see
"Available Information."
 
     Advance Notice Requirements for Stockholder Proposals and Nomination of
Directors.  The EAI By-laws provide that stockholders seeking to bring business
before or nominate directors at any annual meeting of stockholders, must provide
timely notice thereof in writing. To be timely, a stockholder's notice must be
given in writing to the Secretary of EAI not less than 120 days or more than 150
days prior to the meeting. The EAI By-laws also specify certain requirements for
a stockholder's notice to be in proper written form.
 
     The CGCL, as well as the DGCL, is silent as to advance notice of director
nominations and the Sense8 Governing Documents do not contain a provision
requiring such advance notification.
 
     Directors; Vacancies; Removal.  The EAI By-laws provide that EAI shall have
at least three directors, with the exact number fixed by the Board of Directors.
The Sense8 By-laws provide that Sense8 shall have at least three directors, but
the Board of Directors, by resolution, may authorize up to five directors. The
DGCL and the CGCL each allow the boards of directors to be divided into classes.
EAI's Board of Directors is divided into three classes of directors serving
staggered three-year terms. As a result, approximately one-third of EAI's Board
of Directors is elected each year. Sense8's Board of Directors is not divided
into classes. The DGCL and the EAI Governing Documents provide that vacancies on
EAI's Board of Directors may be filled only by the affirmative vote of a
majority of the remaining directors then in office. The Sense8 By-laws provide
that, except for a vacancy created by the removal of a director, vacancies may
be filled by the affirmative vote of a majority of the directors, even if the
directors remaining in the office constitute less than a quorum, or by the
shareholders if the vacancy is not filled by the directors. The Sense8 By-laws
provide that vacancies created by the removal of a director may be filled only
by the approval of the shareholders. The EAI Certificate provides that directors
may be removed only for cause and only by the holders of at least 80% of the
outstanding shares of stock entitled to vote generally in the election of
directors, voting together as a single class. Under the CGCL and the Sense8
By-laws, a director can be removed without cause by the affirmative vote of the
holders of a majority of the outstanding shares entitled to vote at the
election, but no director may be removed when the votes cast against his removal
would be sufficient to elect him if voted cumulatively at an election. The CGCL
and the Sense8 By-laws permit the Board of Directors to declare vacant the
office of a director who has been declared of unsound mind by a court or who has
been convicted of a felony.
 
     Vote on Certain Fundamental Transactions.  The DGCL and the EAI Governing
Documents require that any merger, consolidation, sale of all or substantially
all of the assets, or dissolution of a corporation be approved by the
affirmative vote of the holders of a majority of all outstanding shares of the
corporation entitled to vote thereon. Also see "-- Certain Business
Combinations."
 
     The CGCL requires that a merger, or other reorganization, be approved by
the board of directors of each corporation, and that the principal terms be
approved by the outstanding shares of each class of each corporation. The CGCL
also requires that a sale of all or substantially all of a corporation's assets,
other than in the ordinary course, be approved by the board of directors and a
majority of the outstanding shares entitled to vote thereon.
 
     Special Meetings of Stockholders; Quorum; Stockholder Action By Written
Consent.  Pursuant to the DGCL, special stockholder meetings may only be called
pursuant to a resolution adopted by a majority of the
 
                                       44
<PAGE>   52
 
Board of Directors. The EAI Certificate provides that special meetings of
stockholders of EAI may be called only by a majority of EAI's Board of
Directors, EAI's Chairman or its President. The DGCL provides that a majority of
the shares entitled to vote, represented in person or by proxy, constitute a
quorum at a meeting of stockholders. In addition, the DGCL generally allows for
stockholder actions to be taken pursuant to a written consent signed by
stockholders having not less than the minimum number of votes necessary to
authorize or take such action, provided that a subsequent notice of the taking
of corporate action by less than unanimous written consent is sent to
stockholders who have not consented in writing. The EAI Certificate provides
that the stockholders of EAI may only take actions relating to public offerings
of EAI Common Stock at a duly called annual or special meeting of stockholders
and may not take action by written consent.
 
     The CGCL permits, and the Sense8 Governing Documents provide, that special
meetings of the shareholders may be called by the Board of Directors, the
President or the holders of not less than ten percent of the voting power of the
corporation. The Sense8 By-laws provide that a majority of the shares entitled
to vote, represented in person or by proxy, constitute a quorum at a meeting of
shareholders. The CGCL provides that in no event shall a quorum consist of less
than one-third of the shares entitled to vote. The CGCL and the Sense8 By-laws
permit action by written consent and require written consents to be signed by
the holders of outstanding shares having not less than the minimum number of
votes necessary at a meeting for shareholder action to be approved. But if the
consents of all shareholders have not been solicited in writing, the CGCL and
the Sense8 By-laws require that notice of shareholder approval be given 10 days
prior to the action if approval is by less than unanimous consent.
 
     Issuance of Shares.  The DGCL provides that the directors of a corporation
have the authority to declare issuances of stock. The CGCL and Sense8's
Governing Documents provide that the Board of Directors has the authority to
issue stock.
 
     Amendment of Certificate or Articles of Incorporation and By-laws.  The
DGCL and the EAI Governing Documents allow EAI to amend its certificate of
incorporation if the EAI Board of Directors adopts a resolution approving such
an amendment, and the stockholders thereafter approve the proposed amendment,
either at a special meeting or at the next annual stockholders meeting. In
general, the proposed amendment must be approved at the meeting by a majority of
the outstanding stock entitled to vote thereon.
 
     Under the CGCL, amendments to articles of incorporation must be approved by
the board of directors and a majority of the outstanding shares of each class
entitled to vote. A proposed amendment to the articles of incorporation must be
approved by a majority of outstanding shares of each class if the amendment
effects an exchange or reclassification of shares of such class. The Sense8
By-laws provide, and the CGCL permits, that they may be amended by a majority of
the voting power of Sense8, and, subject to the right of shareholders, the Board
of Directors may also amend the Sense8 By-laws.
 
     Liability and Indemnification of Directors and Officers.  The EAI Governing
Documents provide that EAI shall, subject to certain limitations, indemnify its
directors and officers against expenses (including attorneys' fees, judgments,
fines and certain settlements) actually and reasonably incurred by them in
connection with any suit or proceeding to which they are a party so long as they
acted in good faith and in a manner reasonably believed to be in or not opposed
to the best interests of the corporation, and, with respect to a criminal action
or proceeding, so long as they had no reasonable cause to believe their conduct
to have been unlawful. Section 102 of the DGCL permits a Delaware corporation to
include in its certificate of incorporation a provision eliminating or limiting
a director's liability to a corporation or its stockholders for monetary damages
for breaches of fiduciary duty. DGCL Section 102 provides, however, that
liability for breaches of the duty of loyalty, acts or omissions not in good
faith or involving intentional misconduct, or knowing violation of the law, and
the unlawful purchase or redemption of stock or payment of unlawful dividends or
the receipt of improper personal benefits cannot be eliminated or limited in
this manner. The EAI Certificate includes a provision that eliminates, to the
fullest extent permitted, director liability for monetary damages for breaches
of fiduciary duty.
 
     The CGCL provisions relating to director and officer liability are
substantially similar to those of the DGCL. The CGCL provides that a corporation
shall indemnify a director or officer, made party to a proceeding because of his
or her status as such, who was wholly successful on the merits in the defense of
such
                                       45
<PAGE>   53
 
proceeding. Under the CGCL, the corporation may indemnify a director or officer
against liability incurred in a proceeding provided the director or officer: (a)
acted in good faith; (b) reasonably believed that his or her conduct was in the
corporation's best interests; (c) in the case of any criminal proceeding, he or
she had no reasonable cause to believe that the conduct was unlawful; (d) the
CGCL provides that a corporation's articles of incorporation may limit its
obligation to indemnify directors and officers. Section 204 of the CGCL permits
a California corporation to include in its articles of incorporation a provision
eliminating or limiting a director's liability to a corporation or its
stockholders for monetary damages for breaches of fiduciary duty. Section 204
provides, however, that liability for acts or omissions not in good faith or
involving intentional misconduct or a reckless disregard for a director's duty
to shareholders, or knowing violation of the law, or an unexcused pattern of
inattention or the receipt of improper personal benefits cannot be eliminated or
limited in this manner. The Sense8 Articles include a provision that eliminates,
to the fullest extent permitted, director liability for monetary damages for
breaches of fiduciary duty.
 
     Payment of Dividends.  The DGCL allows a corporation, subject to any
restrictions contained in its certificate of incorporation, to pay dividends out
of its surplus or, in case there is no surplus, out of net profits for the
fiscal year in which declared or out of net profits for the preceding fiscal
year. The EAI Certificate permits the payment of dividends in accordance with
the DGCL, but, to date, EAI has not paid any cash dividends on the EAI Common
Stock.
 
     Under the CGCL, a board of directors is authorized to make distributions to
the shareholders. No distribution may be made, however, if the retained earnings
of the corporation immediately prior to the distribution do not equal or exceed
the amount of the proposed distribution, or if the sum of the corporation's
assets would not equal at least 1 1/4 times its liabilities, or if the current
assets of the corporation would not equal at least its current liabilities. The
Sense8 Governing Documents provide that its Board of Directors may pay dividends
of up to $0.68 per share of Sense8 Series A Preferred and up to $1.77 per share
of Sense8 Series B Preferred in any year. The Sense8 Governing Documents also
authorize its Board of Directors to pay cash dividends on the Sense8 Common
Stock. Sense8 Preferred Stock has preference to cash dividends over Sense8
Common Stock, however, the Preferred Stock dividends are not cumulative.
Dividends other than cash are distributed to holders of Sense8 Common Stock, and
to holders of Sense8 Preferred Stock as though they held the number of shares of
Sense8 Common Stock into which their Sense8 Preferred Stock could be converted.
 
     Appraisal or Dissenters' Rights.  The DGCL provides that stockholders of
corporations being acquired pursuant to a merger have the right to exercise
certain "appraisal rights" to dissent from such corporate action and to demand
payment of the fair value of their shares. Such appraisal rights may be
exercised when the stockholders receive any form of consideration for their
shares other than (i) shares of stock of the surviving corporation, (ii) shares
of stock that are listed on a national securities exchange, or designated as a
national market system security on an interdealer quotation system such as the
NNM, or held of record by more than 2,000 shareholders, (iii) cash in lieu of
fractional shares, or (iv) any combination thereof. Corporations are allowed to
enlarge these statutory rights pursuant to their certificate of incorporation,
but the EAI Certificate does not expand upon such rights.
 
     The CGCL entitles shareholders of a corporation to dissent from and obtain
fair value for their shares in the event of certain corporate actions and
provides that shareholders may dissent from a statutory share exchange.
 
     Stockholder Rights Plan.  EAI has adopted a Stockholder Rights Plan,
pursuant to which holders of EAI Common Stock receive one Right, a preferred
share purchase right, for each outstanding share of EAI Common Stock, with each
Right entitling its holder to purchase one share of EAI Common Stock at an
exercise price of $50 per share, subject to certain adjustments. The Rights
become exercisable if any person or entity acquires 15% or more of the
outstanding EAI Common Stock, or commences a tender or exchange offer that would
cause the offeror to own 15% or more of the outstanding EAI Common Stock. Under
certain circumstances involving an attempted takeover of EAI, holders of Rights
would be entitled to purchase shares of EAI Common Stock or common stock of the
acquiring person or entity having a value equal to two times
 
                                       46
<PAGE>   54
 
the exercise price of the Right. The Rights are redeemable by EAI at a price of
$.01 per Right. See "Description of EAI Stock."
 
     The CGCL authorizes the adoption of a rights plan. Sense8 has not adopted
any shareholder rights plan.
 
     Certain Business Combinations.  Section 203 of the DGCL contains a
"business combination" section applicable to certain Delaware corporations such
as EAI that have a class of voting stock that is (i) listed on a national
securities exchange, (ii) authorized for quotation on the NNM, or (iii) held of
record by more than 2,000 stockholders. Section 203 prohibits certain
transactions between a Delaware corporation and an "interested stockholder,"
which is defined as a person who, together with any affiliates or associates of
such person, beneficially owns, directly or indirectly, 15% or more of the
outstanding voting shares of a Delaware corporation. This provision prohibits
certain business combinations (defined broadly to include mergers,
consolidations, sales or other dispositions of such assets having an aggregate
value in excess of 10% of the consolidated assets of the corporation, and
certain transactions that would increase the interested stockholder's
proportionate share ownership in the corporation) between an interested
stockholder and a corporation for a period of three years after the date the
interested stockholder becomes an interested stockholder, unless (i) the
business combination is approved by the corporation's board of directors prior
to the date the interested stockholder becomes an interested stockholder, (ii)
the interested stockholder acquired at least 85% of the voting stock of the
corporation (other than stock held by directors who are also officers or by
certain employee stock plans) in the transaction in which it becomes an
interested stockholder or (iii) the business combination is approved by a
majority of the board of directors and by the affirmative vote of 66 2/3% of the
outstanding voting stock that is not owned by the interested stockholder. The
DGCL allows Delaware corporations to elect not to be governed by these
provisions. EAI, however, has not so elected, and is subject to the business
combination section of the DGCL. The CGCL does not contain a similar provision.
 
     Interested Director Transactions.  The DGCL and the CGCL both provide that
contracts or transactions in which one or more of the corporation's directors
have an interest ("Interested Contracts or Transactions") are not void or
voidable solely because of such interest or because such director was present at
the directors' or shareholders' meeting where such contracts or transactions
were approved, provided certain conditions are met. Interested Contracts or
Transactions may be approved by a majority vote of the disinterested directors
or by vote of disinterested shareholders if the material facts of the contracts
or transactions and the director's interest in such contracts or transactions
are fully disclosed and a vote is taken in good faith. Furthermore, Interested
Contracts or Transactions may be approved if such contracts or transactions are
shown to be fair and reasonable to the corporation at the time they are
authorized, approved or ratified by the board of directors or shareholders and
separate disinterested shareholder or disinterested director approval is not
required.
 
     Class Vote for Certain Reorganizations.  The CGCL provides, with certain
exceptions, that a class of shares of a corporation is entitled to vote on a
plan of merger or statutory share exchange as a class if any provision of the
plan would entitle the class of shares to vote as a class and, in the case of an
exchange, if the class is included in the plan of exchange. The DGCL does not
contain similar provisions. In addition to the voting requirements discussed
above, anti-takeover legislation adopted in Delaware imposes additional
restrictions on mergers and other business combinations between certain
stockholders and the corporation.
 
                                 LEGAL MATTERS
 
     The validity of the shares of EAI Common Stock to be issued in connection
with the Merger have been passed upon for EAI by Gardner, Carton & Douglas,
special securities counsel to EAI.
 
                                  TAX OPINION

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of shareholders' equity (deficit) and of
cash flows present fairly, in all material respects, the financial position of
Sense8 Corporation and its subsidiary at December 31, 1997 and 1996, and the
results of their operations and their cash flows for the years then ended, in
conformity with generally accepted accounting principles. These consolidated
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these consolidated financial
statements based on our audits. We conducted our audits of these statements in
accordance with generally accepted auditing standards which require that we plan
and perform the audit to obtain reasonable assurance about whether the
consolidated financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the consolidated financial statements, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.
 
     The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in Note
1 to the consolidated financial statements, the Company has incurred recurring
losses from operations and has a net capital deficiency that raise substantial
doubt about its ability to continue as a going concern. The consolidated
financial statements do not include any adjustments that might result from the
outcome of this uncertainty. As described in Note 1, the Company has entered
into a definitive agreement dated April 11, 1998, to be acquired by Engineering
Animation, Inc. Consummation of the proposed acquisition is subject to certain
conditions of closing.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 -- THE COMPANY AND SIGNIFICANT MATTERS:
 
     Sense8 Corporation (the "Company") was incorporated in California in 1990
and designs and markets software development tools for the creation of virtual
reality applications. The Company's products are distributed in the United
States by the Company and internationally through a network of independent
distributors and value-added resellers, primarily located in Europe.
 
     During 1996, the Company formed Sense8 SA (the "Subsidiary") to distribute
the Company's products and to establish a market presence throughout Europe. The
Subsidiary was incorporated in Switzerland and is wholly-owned by the Company.
During 1997, the Company closed Sense8 SA and returned the management of
European distribution to the United States.
 
     The Company has incurred recurring losses from operations and has a net
capital deficiency that raise substantial doubt about its ability to continue as
a going concern. The consolidated financial statements do not include any
adjustments that might result from the outcome of this uncertainty. However, on
April 11, 1998, the Company entered into a definitive agreement dated April 11,
1998 to be acquired by Engineering Animation, Inc. (EAI). In connection
therewith, the Company and EAI entered into an interim management agreement
which provides for joint management of the Company through consummation of the
acquisition. EAI has provided working capital to the Company since the date of
the definitive agreement.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
PRINCIPLES OF CONSOLIDATION
 
     The accompanying consolidated financial statements include the accounts of
Sense8 Corporation and its wholly-owned subsidiary. All intercompany accounts
and transactions have been eliminated in consolidation.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
 
CASH EQUIVALENTS
 
     The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. Cash equivalents
consist principally of bank deposits and money-market accounts that are stated
at cost, which approximates fair value.
 
REVENUE RECOGNITION
 
     Revenues from software license fees and product sales are recognized upon
product shipment and fulfillment of acceptance terms, if applicable, provided
that no significant obligations exist and collection of the resulting receivable
is probable. Revenues from software support contracts are recognized ratably
over the course of the support term. Revenues from consulting services are
recognized using the percentage of completion method. Revenues from training
services are recognized as such services are performed.
 
CONCENTRATIONS OF CREDIT RISK
 
     Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist primarily of cash and cash equivalents and
trade accounts receivable, which are generally not collateralized. The Company
limits its exposure to credit loss by placing its cash and cash equivalents with
 
                                       F-7
<PAGE>   63
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
high credit quality financial institutions. Concentrations of credit risk with
respect to trade accounts receivable are considered to be limited due to the
quality of customers comprising the customer base and their dispersion across
different businesses and geographic markets. The Company performs on-going
credit evaluations of its customers' financial condition to determine the need
for an allowance for doubtful accounts. The aggregate accounts receivable from
one customer represented 10 percent and 19 percent of total accounts receivable
at December 31, 1997 and 1996, respectively.
 
SALES TO SIGNIFICANT CUSTOMERS
 
     During the year ended December 31, 1997, sales to one customer represented
12 percent of net revenues. During the year ended December 31, 1996, sales to
two customers represented 21 percent and 15 percent of net revenues,
respectively.
 
INVENTORIES
 
     Inventories are stated at the lower of cost, determined on a first-in
first-out (FIFO) basis, or market value and comprise primarily hardware products
purchased for re-sale.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is provided on the straight-line basis over the
estimated useful lives of the assets, which range from two to seven years.
Amortization of leasehold improvements is computed using the straight-line
method over the shorter of the remaining lease term or the estimated useful life
of the related asset, typically three years.
 
STOCK-BASED COMPENSATION
 
     The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of APB No. 25, "Accounting for Stock Issued to
Employees," and complies with the disclosure provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation."
 
FOREIGN CURRENCY TRANSLATION
 
     The Company had a subsidiary in Switzerland through October 1997. The
functional currency of this entity was the local currency. Accordingly, all
assets and liabilities of these entities are translated at the current exchange
rate in effect at the balance sheet date and revenues and expenses are
translated at the average exchange rates in effect during the reporting period.
During the years ended December 31, 1997 and 1996, foreign currency transaction
and translation gains and losses were immaterial.
 
RESEARCH AND DEVELOPMENT
 
     Costs incurred in the research and development of new products and
enhancements to existing products are charged to expense as incurred until the
technological feasibility of the product or enhancement has been established.
After establishing technological feasibility, any additional development costs
incurred through the date the product is available for general release would be
capitalized and amortized over the greater of the estimated product life or on a
ratio of current product revenues to total projected product revenues. No costs
have been capitalized to date as the impact on the financial statements for all
periods presented is immaterial.
 
INCOME TAXES
 
     Income taxes are accounted for using an asset and liability approach which
requires the recognition of taxes payable or refundable for the current year and
deferred tax liabilities and assets for the future tax consequences of events
that have been recognized in the Company's financial statements or tax returns.
The measurement of current and deferred tax liabilities and assets are based on
provisions of the enacted tax law;
 
                                       F-8
<PAGE>   64
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
the effects of future changes in tax laws or rates are not anticipated. The
measurement of deferred tax assets is reduced, if necessary, by the amount of
any tax benefits that, based on available evidence, are not expected to be
realized.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The Company's financial instruments, including cash equivalents, accounts
receivable, accounts payable and notes payable, have carrying amounts which
approximate fair value due to the relatively short maturity of these
instruments.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" ("SFAS 130"). This statement will be effective for the Company's year
ending December 31, 1998. The statement establishes presentation and disclosure
requirements for reporting comprehensive income. Comprehensive income includes
charges or credits to equity that are not the result of transactions with
shareholders. The Company expects there will be no material impact on its
consolidated financial position or results of operations as a result of the
adoption of this new accounting standards.
 
     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS 131"). This statement will be effective for the Company's year ending
December 31, 1998. The statement requires the Company to report certain
financial information about operating segments. It also requires that the
Company report certain information about its services, the geographic areas in
which it operates and its major customers. The method specified in SFAS 131 for
determining what information to report is referred to as the "management
approach." The management approach is based on the way that management organizes
the segments within the enterprise for making operating decisions and assessing
performance. The adoption of SFAS 131 is not expected to have a significant
impact on segment disclosures of the Company.
 
     In October 1997, the AICPA issued SoP 97-2, "Software Revenue Recognition,"
which provides guidance on applying generally accepted accounting principles in
recognizing revenue on software transactions. SoP 97-2 is effective for
transactions entered into in fiscal years beginning after December 15, 1997.
Earlier application is encouraged as of the beginning of fiscal years or interim
periods for which financial statements or information have not been issued.
Retroactive application of the provisions of this SoP is prohibited. The Company
has assessed the provisions of the SoP 97-2 and does not expect that adoption
will have a material impact on its consolidated financial statements.

NOTE 5 -- NOTES PAYABLE:
 
     In June 1997, the Company issued convertible promissory notes payable to
two customers totaling $300,000 and two shareholders totaling $84,000 which bear
interest at 12% per annum payable quarterly. The notes are convertible at the
option of the holder into shares of Series B Convertible Preferred Stock at an
initial price of $17 per share. Principal and unpaid interest on the notes are
due in June 2000, but shall be immediately due and payable upon either the sale
by the Company of equity securities for gross proceeds totaling $2,000,000 or
more or upon sale of substantially all of the Company's capital stock. See Notes
1 and 10. In connection with the promissory notes, the Company issued warrants
to purchase Series B Convertible Preferred Stock. See Note 8.
 
     In July 1997, the Company borrowed $200,000 from a leasing company. The
loan is secured by certain equipment purchased by the Company. Principal and
interest payments are payable monthly through April 2001. The annual interest
rate is 17.43 percent. At December 31, 1997, the outstanding balance was
$183,000.

     Management believes that, based on a number of factors, it is more likely
than not that the deferred tax assets will not be recovered, therefore a full
valuation reserve has been recorded.
 
     At December 31, 1997, the Company had federal and state net operating loss
carryforwards of approximately $1,400,000 and $925,000 respectively, which are
available to reduce future taxable income. Such carryforwards expire in various
amounts through 2012. The income tax benefit from the utilization of net
operating loss carryforwards may be limited in certain circumstances including,
but not limited to cumulative stock ownership changes of more than 50 percent
over a three-year period. See Note 1 regarding the acquisition.

leases, which expire through March 2001. The accompanying consolidated financial
statements reflect rent expense on a straight-line basis over the terms of the
respective lease agreements. Total rent expense under noncancelable operating
leases was $379,000 and $405,000 for the years ended December 31, 1997 and 1996,

     The holders of Preferred Stock have certain rights and preferences with
respect to conversion, voting, dividends and liquidation as follows:
 
CONVERSION
 
     Each share of Preferred Stock is convertible at the option of the holder at
any time into Common Stock at the initial conversion rate of one share of Common
Stock for each share of Preferred Stock. The initial conversion rate of each
series of Preferred Stock is subject to adjustment as provided in the Articles
of Incorporation. Each share of Preferred Stock shall automatically be converted
into shares of Common Stock at the then effective conversion rate upon the
Company's sale of its common stock in an underwritten public offering pursuant
to a registration statement under the Securities Act of 1933.
 
VOTING
 
     Each holder of Series A and Series B Preferred Stock is entitled to the
number of votes equal to the number of shares of Common Stock into which the
shares of Preferred Stock could be converted.
 
DIVIDENDS
 
     Holders of Series A and Series B Preferred Stock are entitled to a
dividend, when and if declared by the Board of Directors, at the fixed rate of
$0.68 and $1.77, respectively, per share per annum, prior and in preference to
any distribution on the Common Stock. Such dividends are not cumulative.
 
LIQUIDATION
 
     In the event of any liquidation, dissolution or winding up of the Company,
the holders of the Series A and Series B Preferred Stock shall be entitled to
receive, prior and in preference to any distribution to the holders of the
Common Stock, the amount of $6.80 and $17.66, respectively, per share, plus an
amount equal to all declared but unpaid dividends on such shares. The remaining
assets, if any, shall be distributed among the holders of Preferred Stock and
Common Stock pro rata based on the number of shares of Common Stock held by
each, determined on an as-converted basis. If the Company's funds are
insufficient to permit the full payment of such preferential amounts, funds
shall be distributed ratably among the holders of Series A and Series B
Preferred Stock in proportion to the respective liquidation preference of each
series.
 
WARRANTS
 
     In October 1995, the Company issued warrants to purchase 4,000 shares of
Series A Convertible Preferred Stock in connection with a working capital line
of credit agreement. The warrant has an exercise price of $6.80 per share and
expires in October 2000. At the date of grant, the value of the warrants was not
material to the financial statements. At the election of the holder, the Company
shall purchase the warrants for cash upon the closing of any acquisition in an
amount equal to the fair market value of the shares, assuming exercise, less the
exercise price of the warrant.
 
     In May 1996, the Company issued warrants to purchase 4,125 shares of Series
A Convertible Preferred Stock in connection with a working capital line of
credit agreement. The warrant has an exercise price of $6.80 per share and
expires in May 2001. At the date of grant, the value of the warrants was not
material to the financial statements. At the election of the holder, the Company
shall purchase the warrants for cash upon the

closing of any acquisition in an amount equal to the fair market value of the
shares, assuming exercise, less the exercise price of the warrant.
 
     In June 1997, the Company issued warrants to purchase 22,590 shares of
Series B Convertible Preferred Stock in connection with issuance of convertible
notes payable. The warrants have an exercise price of $17.00 per share and
expire in June 2002. At the date of the grant, the warrants had a value of
approximately $120,000 which is being amortized as interest expense over the
term of the related debt.
 
     In July 1997, the Company issued warrants to purchase 5,000 shares of
Common Stock in connection with a Note Payable. The warrant has an exercise
price of $0.01 per share and expires in July 2007. At the date of grant, the
value of the warrants was not material to the financial statements.
 
NOTE 9 -- EMPLOYEE BENEFITS:
 
STOCK OPTIONS
 
     The 1997 Stock Option Plan (the "Plan") provides for the grant of incentive
stock options and nonqualified stock options for the purchase of up to an
aggregate of 300,853 shares of the Company's common stock by officers,
employees, consultants and directors of the Company. The Plan amends the 1993
Stock Option Plan (the "1993 Plan") and includes all grants and activity under
the 1993 Plan, as well as other nonqualified stock option grants approved by the
Board of Directors. The Board of Directors is responsible for administration of
the Plan. The Board of Directors determines the term of each option, option
exercise price, number of shares for which each option is granted and the rate
at which each option is exercisable. Options generally vest ratably over four
years. The Company may not grant an employee incentive stock options with a fair
value in excess of $100,000 that is first exercisable during any one calendar
year.
 
     Incentive stock options may be granted to employees at an exercise per
share of not less than the fair value per common share on the date of the grant
(not less than 110% of the fair value in the case of holders of more than 10% of
the Company's voting stock). Nonqualified stock options may be granted to any
officer, employee, director or consultant at an exercise price per share (not
less than 85% of the fair value), as determined by the Company's Board of
Directors.
 
     Options granted under the Plan generally expire 10 years from the date of
the grant (five years for incentive stock options granted to holders of more
than 10% of the Company's voting stock).
 
     During the years ended December 31, 1997 and 1996, respectively, no
compensation costs were recognized in connection with option grants. Had
compensation cost for the Company's Option Plan and separate approval by the
Board of Directors been determined based on the fair value at the grant dates,
as prescribed in SFAS 123, the Company's net income (loss) would have been as
follows:

and as a result Sense8 shall become a wholly-owned subsidiary of EAI;
 
     WHEREAS, EAI, Sub and Sense8 have subsequently determined that it is
preferable that the business combination of EAI and Sense8 be accomplished by a

          (a) Each share of Sense8 Series A Preferred Stock issued and
     outstanding immediately prior to the Effective Time, other than Dissenters'
     Shares (as defined below), shall be converted into the right to receive
     shares of EAI Common Stock in the amount equal to the sum of (i) the Per
     Share Series A Preference Amount and (ii) the Exchange Ratio (as defined
     below).
 
          (b) Each share of Sense8 Series B Preferred Stock issued and
     outstanding immediately prior to the Effective Time, other than Dissenters'
     Shares, shall be converted into the right to receive shares of EAI Common
     Stock in the amount equal to the sum of (i) the Per Share Series B
     Preference Amount and (ii) the Exchange Ratio (as defined below).
 
          (c) Each share of Sense8 Common Stock issued and outstanding
     immediately prior to the Effective Time, other than Dissenters' Shares,
     shall be converted into the right to receive shares of EAI Common Stock in
     an amount equal to the Exchange Ratio (as defined below).
 
          (d) The "Exchange Ratio" shall be determined as follows: each share of
     Sense8 Stock shall be exchanged for that number of shares of EAI Common
     Stock equal to the quotient, carried to six decimal places, of (x) the
     number obtained by dividing the Remaining Total Merger Consideration (as
     defined below) by the total of the number of shares of Sense8 Stock
     outstanding immediately prior to the Effective Time (omitting any shares of
     Sense8 Stock issued after April 11, 1998 as a result of exercise of a
     Sense8 Option) plus the number of shares of Sense8 Stock issuable upon the
     exercise of all Sense8 Warrants outstanding immediately prior to the
     Effective Time, divided by (y) the EAI Stock Value. The "Remaining Total
     Merger Consideration" is the difference of (i) the Total Merger
     Consideration less (ii) the sum of the Series A Preference Amount and the
     Series B Preference Amount.
 
          (e) No fractional shares of EAI Common Stock shall be issued, and in
     lieu thereof, EAI shall pay to each former shareholder of Sense8 who
     otherwise would be entitled to receive such fractional share an amount in
     cash determined by multiplying (i) the EAI Stock Value by (ii) the fraction
     of a share (rounded to the nearest thousandth when expressed as an Arabic
     number) of EAI Common Stock to which such holder would otherwise be
     entitled to receive pursuant to this Section 2.3.

<PAGE>   79
 
          (f) All of the shares of Sense8 Stock converted into EAI Common Stock
     pursuant to this Article shall no longer be outstanding and shall
     automatically be canceled and cease to exist at the Effective Time, and
     each Sense8 Certificate shall thereafter represent the right to receive
     (i) a certificate representing the number of whole shares of EAI Common
     Stock, and (ii) cash in lieu of fractional shares, into which the shares of
     Sense8 Stock represented by such Sense8 Certificate have been converted.
     If, prior to the Effective Time, the outstanding shares of EAI Common Stock
     or Sense8 Stock shall have been increased, decreased, changed into or
     exchanged for a different number or kind of shares or securities as a
     result of a reorganization, recapitalization, reclassification, stock
     dividend, stock split, reverse stock split, or other similar change in
     capitalization, then an appropriate and proportionate adjustment shall be
     made to this Article.
 
          (g) Shares of Sense8 Stock with respect to which dissenters rights
     have been properly demanded in accordance with the CGCL ("Dissenters'
     Shares") shall not be converted into EAI Common Stock at the Effective
     Time, but shall be converted into the right to receive from EAI such
     consideration as is determined to be due with respect to such Dissenters'
     Shares pursuant to the provisions of the CGCL. Sense8 shall give EAI (i)
     prompt notice of any written demands for appraisals, withdrawals or demands
     for appraisal and any other instruments in respect thereof received by
     Sense8 and (ii) the opportunity to direct all negotiations and proceedings
     with respect to demands for appraisal. Sense8 shall not voluntarily make
     any payment with respect to any demands for appraisal and will not, except
     with the prior written consent of EAI, settle or offer to settle any such
     demands.
 
          (h) At the Effective Time, all shares of Sense8 Stock that are owned
     by Sense8 as treasury stock and all shares of Sense8 Stock that are owned,
     directly or indirectly, by Sense8, EAI or any wholly-owned subsidiary of
     EAI shall be canceled and shall cease to exist, and no stock of EAI or
     other consideration shall be delivered in exchange therefor. All shares of
     EAI Common Stock that are owned by Sense8 shall become treasury stock of
     EAI.
 
          (i) After the Effective Time, there shall be no transfers on Sense8's
     stock transfer books of shares of Sense8 Stock.
 
     2.4. Exchange of Shares.  (a) At the Closing, each shareholder of Sense8
shall have the right to deliver to EAI a properly completed letter of
transmittal and Sense8 Certificates representing all of the issued and
outstanding shares of Sense8 Stock owned by such shareholder, duly endorsed for
transfer or accompanied by duly executed stock powers, free and clear of all
options, liens, claims, charges, restrictions and other encumbrances of any
nature whatsoever, other than federal and state securities law restrictions.
Upon proper surrender of a Sense8 Certificate for exchange and cancellation to
EAI, and in accordance with and subject to the other provisions of this
Agreement and the letter of transmittal, the holder of such Sense8 Certificate
shall receive in exchange therefor (i) a certificate representing that number of
whole shares of EAI Common Stock to which such holder of Sense8 Stock shall have
become entitled, and (ii) a check representing the amount of any cash in lieu of
fractional shares which such holder has the right to receive. The Sense8
Certificate so surrendered shall forthwith be canceled. No interest shall be
paid or accrued on any cash in lieu of fractional shares payable to holders of
Sense8 Certificates.
 
     (b) If any certificate representing shares of EAI Common Stock is to be
issued in a name other than that in which the Sense8 Certificate surrendered in
exchange therefor is registered, it shall be a condition of the issuance thereof
that the Sense8 Certificate shall be properly endorsed (or accompanied by an
appropriate instrument of transfer) and otherwise in proper form for transfer,
and that the person requesting such exchange shall pay to EAI in advance any
transfer or other taxes required by reason thereof, or shall establish to the
satisfaction of EAI that such tax has been paid or is not payable.
 
     (c) In the event any Sense8 Certificate shall have been lost, stolen or
destroyed, the person so claiming shall make an affidavit of that fact and, if
required by EAI, post a bond in such amount as EAI may determine is reasonably
necessary as indemnity against any claim that may be made against it with
respect to such Sense8 Certificate. Thereafter, EAI shall issue in exchange for
such lost, stolen or destroyed Sense8 Certificate the shares of EAI Common Stock
and any cash in lieu of a fractional share deliverable in respect thereof
pursuant to this Agreement.

     2.5. Warrants to Acquire Sense8 Stock.
 
     (a) At the Effective Time, pursuant to its terms, each outstanding Sense8
Warrant shall automatically be deemed to constitute a warrant to acquire, on the
same terms and conditions as were applicable under such Sense8 Warrant, (i) the
same number of shares of EAI Common Stock as such Sense8 Warrant would have been
exchangeable for had such Sense8 Warrant been exercised in full immediately
prior to the Effective Time and (ii) at an exercise price per share (rounded up
to the nearest whole cent) equal to (A) the aggregate exercise price for the
shares of Sense8 Stock otherwise purchasable pursuant to such Sense8 Warrant
divided by (B) the number of shares of EAI Common Stock deemed to be purchasable
under such warrant to acquire EAI Common Stock; provided, however, that the
number of shares of EAI Common Stock that may be purchased upon exercise of such
Sense8 Warrant shall not include any fractional share and, upon exercise of such
Sense8 Warrant, a cash payment shall be made for any fractional share based upon
the closing price of a share of EAI Common Stock as reported on the NNM on the
trading day immediately preceding the date of exercise.
 
     (b) As soon as practicable after the Effective Time, EAI shall deliver to
the holders of Sense8 Warrants appropriate notices setting forth such holders'
rights and the agreements evidencing such Sense8 Warrants shall be deemed to be
appropriately amended so that such Sense8 Warrants shall represent rights to
acquire EAI Common Stock on terms and conditions as contained in the outstanding
Sense8 Warrants (subject to the adjustments required by this Section 2.5 after
giving effect to the conversion as set forth above).
 
     2.6. Options to Acquire Sense8 Common Stock.
 
     (a) At the Effective Time, each outstanding Sense8 Option, whether vested
or unvested, shall be assumed by EAI. Each such Sense8 Option so assumed by EAI
under this Agreement shall continue to have and be subject to the same terms and
conditions set forth in the applicable Sense8 Stock Option immediately prior to
the Effective Time. Each such Sense8 Option shall thereafter be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such Sense8 Option, (i) the same number of shares of EAI Common
Stock as such Sense8 Option would have been exchangeable for had such Sense8
Option been exercised in full immediately prior to the Merger and (ii) at an
exercise price per share (rounded up to the nearest whole cent) equal to (A) the
aggregate exercise price for the shares of Sense8 Common Stock otherwise
purchasable pursuant to such Sense8 Option divided by (B) the number of shares
of EAI Common Stock deemed to be purchasable under such option to acquire EAI
Common Stock; provided, however, that the number of shares of EAI Common Stock
that may be purchased upon exercise of such Sense8 Option shall not include any
fractional share and, upon exercise of such Sense8 Option, a cash payment shall
be made for any fractional share based upon the closing price of a share of EAI
Common Stock as reported on the NNM on the trading day immediately preceding the
date of exercise. It is the intention of the parties that the Sense8 Options
assumed by EAI, to the extent that they pertain to the purchase of EAI Common
Stock thereunder, shall continue to qualify as incentive stock options under
Section 422 of the Code to the same extent immediately after the Closing as such
Sense8 Options so qualified immediately prior to the Closing. As a condition to
EAI's obligations to consummate the Merger, each holder of a Sense8 Option,
which by its terms does not automatically convert in the Merger into an option
to purchase EAI Common Stock, shall have consented to the above described
assumption pursuant to a written agreement or instrument signed by such holder.
 
     (b) As soon as practicable after the Effective Time, EAI shall deliver to
the holders of Sense8 Options appropriate notices setting forth such holders'
rights and the agreements evidencing the grants of such Sense8 Options shall be
deemed to be appropriately amended so that such Sense8 Options shall represent
rights to acquire EAI Common Stock on terms and conditions as contained in the
outstanding Sense8 Options (subject to the adjustments required by this Section
2.6 after giving effect to the assumption by EAI as set forth above).
 
     (c) EAI shall file within three (3) business days following the Closing
Date and use its reasonable efforts to file and maintain the effectiveness of a
Form S-8 registration statement covering the Sense8 Options (and maintain the
current status of the prospectus or prospectuses referred to therein) for so
long as such Sense8 Options remain outstanding.

                    REPRESENTATIONS AND WARRANTIES OF SENSE8
 
     Except as disclosed by Sense8 in the disclosure schedule delivered pursuant

properties and assets and to carry on its business as it is now being conducted,
and is duly licensed or qualified to do business and is in good standing in each
jurisdiction in which the nature of the business conducted by it or the
character or location of the properties and assets owned or leased by it makes
such licensing or qualification necessary. Correct and complete copies of the
Articles of Incorporation and By-Laws of Sense8, as in effect on April 11, 1998,
have been made available to EAI by Sense8.
 
     (b) Sense8 does not own of record or beneficially, directly or indirectly,

     (c) The minute books of Sense8 accurately reflect in all material respects
all actions taken by the boards of directors, including committees thereof, and
the shareholders of Sense8.

shares of Sense8 Stock, no other corporate proceedings on the part of Sense8 are
necessary to approve this Agreement or to consummate the transactions
contemplated hereby. This Agreement has been duly and validly executed and
delivered by Sense8 and constitutes a valid and binding obligation of Sense8,
enforceable against Sense8 in accordance with its terms.
 
     (b) The execution and delivery of this Agreement by Sense8, the
consummation by Sense8 of the transactions contemplated hereby, and the
compliance by Sense8 with the terms or provisions hereof, shall not

of, accelerate the performance required by, or result in the creation of any
liens, pledges, charges, encumbrances or security interests of any kind
(collectively, "Liens") upon any of the properties or assets of Sense8 under any
note, bond, mortgage, indenture, deed of trust, license, lease, contract,
agreement or other instrument or obligation to which Sense8 is a party, or by
which it or any of its properties or assets may be bound or affected, other than

could not have a Material Adverse Effect on Sense8.
 
     3.4. Consents and Approvals.  Except for (i) the filing of Agreement of
Merger with the California Secretary pursuant to the CGCL, (ii) the approval of
this Agreement by the requisite vote of the holders of Sense8 Stock, and (iii)
the filing with the Securities and Exchange Commission (the "SEC") and

the part of, or filing, registration or qualification with, or notice to
(collectively, the "Consents") any court, administrative agency, commission or

or foreign (each a "Governmental Authority"), or with any third party are
necessary in connection with the execution and delivery by Sense8 of this
Agreement and the consummation by Sense8 of the Merger and the other
transactions contemplated by this Agreement.
 
     3.5. Reports.  Sense8 has timely filed all reports, registrations and
statements required to be filed since January 1, 1996 with any Governmental

franchises, permits and authorizations necessary for the lawful conduct of its
business and has complied with and is not in default under any law, statute,
code, ordinance, rule, regulation, judgment, order, writ, decree or injunction
of any Governmental Authority applicable to Sense8, other than licenses,
franchises, permits or authorizations or failures to comply or defaults which,
individually or in the aggregate, could not have a material adverse effect on
the business, properties, operations or financial condition (a "Material Adverse
Effect") of Sense8.
 
     3.7. Financial Statements.  Sense8 has previously provided EAI with correct
and complete copies of the following (collectively, the "Sense8 Financial
Statements"): (a) the unaudited consolidated balance sheet of Sense8 as of
December 31, 1997 and the unaudited consolidated balance sheet of Sense8 as of
December 31, 1996, and the related unaudited consolidated statements of income
and retained earnings and cash flows for the fiscal year ended December 31,
1997, and unaudited consolidated statements of income and retained earnings and
cash flows for the fiscal years ended December 31, 1996 and 1995, and (b) the
unaudited consolidated balance sheet of Sense8 as of March 31, 1998 and the
related unaudited consolidated statements of income for the periods then ended
(the "Interim Financial Statements"), which are attached as part of the
Disclosure Schedule. The Sense8 Financial Statements fairly present the
consolidated financial position of Sense8 and its subsidiaries as of the dates
thereof, and the results of operations and cash flows of Sense8 for the
respective fiscal periods or as of the respective dates thereof. Each of the
Sense8 Financial Statements, including the notes thereto, has been prepared in
accordance with generally accepted accounting principles ("GAAP") consistently
applied during the periods involved. The books and records of Sense8 have been,
and are being, maintained in accordance with all applicable legal and accounting
requirements.

Sense8 has not incurred any material liability that is not disclosed in the
Interim Financial Statements, (ii) no event has occurred which, individually or
in the aggregate, could have a Material Adverse Effect on Sense8, and (iii)
Sense8 has carried on its business in the ordinary and usual course.
 
     (b) Except as set out in Section 3.8 of the Disclosure Schedule, since
December 31, 1997, Sense8 has not (i) increased the salaries, wages, or other

<PAGE>   83
 
payable to any director, executive officer or employee, or (ii) granted any
severance or termination pay, or (iii) paid or accrued any bonuses or
commissions, or (iv) suffered any strike, work stoppage, slowdown, or other
labor disturbance which could, either individually or in the aggregate, result
in a Material Adverse Effect on Sense8.
 
     3.9. Legal Proceedings and Restrictions.  (a) There are no actions, suits,
proceedings, claims or investigations pending, or to the knowledge of Sense8,
threatened against or affecting Sense8 at law or in equity or before any
Governmental Authority.
 
     (b) There is no judgment, order, writ, decree, injunction or regulatory
restriction imposed upon Sense8 or its assets which has had, or could reasonably
be expected to have, a Material Adverse Effect on Sense8.
 
     3.10. Taxes and Tax Returns.
 
     (a) (i) Sense8 (which term for purposes of this Section 3.10 shall include
     former subsidiaries of Sense8 for periods during which they were owned) has
     timely filed (when due or prior to the expiration of any extension of the
     time to file) correct and complete Returns in respect of Taxes required to
     be filed; all Taxes shown on such Returns or otherwise known by Sense8 to
     be due or payable have been timely paid; no adjustment relating to any such
     Return has been proposed in writing by any Governmental Authority, except
     proposed adjustments that have been resolved prior to April 11, 1998; and
     there are no outstanding summons, subpoenas or written requests for
     information with respect to any such Returns or the Taxes reflected
     thereon. To Sense8's knowledge there is no basis for imposing any
     additional Taxes on it other than the Taxes shown on such Returns. There
     are no outstanding waivers or agreements extending the statute of
     limitations for any period with respect to any Tax to which Sense8 may be
     subject and Sense8 is not under audit by any Governmental Authority for any
     Tax. There are no Tax liens on any assets of Sense8 other than liens for
     Taxes not yet due or payable;
 
          (ii) Sense8 has paid, on the basis of Sense8's good faith estimate of
     the required installments, all estimated Taxes required to be paid under
     Section 6655 of the Code or any comparable provision of state, local or
     foreign law; and all Taxes which shall be due and payable for any period or
     portion thereof ending on or prior to the Closing Date shall have been paid
     or shall be reflected on Sense8's books as an accrued Tax liability, either
     current or deferred. The amount of such Tax liabilities as of March 31,
     1998 shall be set forth in Section 3.10 of the Disclosure Schedule. All
     Taxes required to be withheld, collected or deposited by Sense8 during any
     taxable period for which the applicable statute of limitations on
     assessment remains open have been timely withheld, collected or deposited
     and, to the extent required, have been paid to the relevant Governmental
     Authority;
 
          (iii) For each taxable period for which the statute of limitations on
     assessment remains open, Sense8 has not (A) been either a common parent
     corporation or a member corporation of an affiliated group of corporations
     filing a consolidated Federal income tax return, or (B) acquired any
     corporation that filed a consolidated Federal income tax return with any
     other corporation that was not also acquired by Sense8; and no other entity
     that was included in the filing of a Return with Sense8 on a consolidated,
     combined, or unitary basis has left Sense8's consolidated, combined or
     unitary group in a taxable year for which the statute of limitations on
     assessment remains open. Sense8 has not been at any time a member of any
     partnership, limited liability company or joint venture or the holder of a
     beneficial interest in any trust for any period for which the statute of
     limitations for any Tax potentially applicable as a result of such
     membership or holding has not expired;
 
          (iv) No consent under Section 341(f) of the Code has been filed with
     respect to Sense8; and
 
          (v) There is no significant difference on the books of Sense8 between
     the amounts of the book basis and the tax basis of assets (net of
     liabilities) that is not accounted for by an accrual on the books for
     Federal income tax purposes.

          (vi) Does not have any income reportable for a period ending after the
     Closing Date but attributable to an installment sale occurring in or a

     transaction or from such change in accounting method (other than a deferred
     intercompany transaction), or deferred gain or loss arising out of any
     deferred intercompany transaction;
 
          (vii) Does not have any unused net operating loss, unused net capital

Agreement shall take all such necessary or advisable action.

Takeover Proposal and the specific terms and conditions thereof, and has been
given copies of such Takeover Proposal; (ii) such third party has made a written
Takeover Proposal to the Board of Directors of Sense8, which Takeover Proposal
identifies a price or range of values to be paid and based on the advice of
Sense8's investment bankers, the Board of Directors of Sense8 has determined
that such Takeover Proposal is financially more favorable to the shareholders of
Sense8 than the terms of the Merger; (iii) Sense8's Board of Directors has
determined, based on the advice of Sense8's investment bankers, that such third
party is financially capable of consummating the transactions specified in the
Takeover Proposal; and (iv) the Board of Directors of Sense8 has determined,

form satisfactory to EAI.
 
     (c) In addition to the foregoing requirements, Sense8 shall not accept or
enter into any agreement concerning a Takeover Proposal until at least 48 hours

<PAGE>   94
 
equity interest in, or a substantial portion of the assets of, Sense8 other than

     (e) Sense8 shall be entitled to furnish a copy of this Section 6.6 to any
third party who expresses an interest in making a Takeover Proposal after the
execution of this Agreement.

          (a) Sense8 and EAI will not file any tax return or make any disclosure
     that is inconsistent with the Merger qualifying as a reorganization under
     Section 368(a) of the Code. Sense8 and EAI will, and Sense8 will use its
     best efforts to cause its shareholders to, file all Returns and statements
     as required by the regulations under Section 368 of the Code as they apply
     to the Merger.
 
          (b) Sense8 will use its best efforts to provide EAI with information

                              CONDITIONS PRECEDENT
 
     7.1. Conditions to Each Party's Obligation To Effect the Merger.  The
respective obligation of each party to effect the Merger shall be subject to the
satisfaction at or prior to the Effective Time of the following conditions:
 
          (a) Approvals and Consents.  All regulatory approvals required to
     consummate the transactions contemplated hereby shall have been obtained
     and shall remain in full force and effect and all statutory waiting periods
     in respect thereof shall have expired (all such approvals and the
     expiration of all such waiting periods being referred to herein as the
     "Requisite Regulatory Approvals"), all consents necessary to transfer all
     of Sense8's rights, title and interest to its facilities located on
     Shoreline Highway, Mill Valley, California shall have been obtained in
     accordance with the lease thereof, and shall remain in full force and
     effect.
 
          (b) No Injunctions or Restraints; Illegality.  No order, injunction or
     decree issued by any Governmental Authority or other legal restraint or
     prohibition preventing the consummation of the Merger or any of the other
     transactions contemplated by this Agreement shall be in effect. No law,
     statute, rule, regulation, order, injunction or decree shall have been
     enacted, entered, promulgated or enforced by any Governmental Authority
     which prohibits, materially restricts or makes illegal the consummation of
     the Merger or the other transactions contemplated by this Agreement.
 
          (c) Sense8 Shareholder Approval.  This Agreement and the transactions
     contemplated hereby shall have been approved by the requisite holders of
     the issued and outstanding shares of Sense8 Stock.
 
          (d) Federal Tax Opinion.  Sense8 and the shareholders of Sense8 shall
     have received an opinion of Brobeck, Phleger & Harrison LLP, in form and
     substance reasonably satisfactory to them prior to the mailing of the S-4,
     which opinion shall not have been amended, modified or withdrawn as of the
     Closing, substantially to the effect that:
 
             (i) The Merger will constitute a tax free reorganization under
        Section 368(a)(1)(A) of the Code and Sense8 and EAI will each be a party
        to the reorganization; and
 
             (ii) The discussion in the S-4 under the caption "The
        Merger -- Certain Federal Income Tax Consequences" insofar as it relates
        to matters of federal income tax law is a fair and accurate summary of
        such matters.
 
In rendering such opinion, counsel may require and rely upon assumptions and
representations contained in certificates of officers of Sense8, EAI and others.

     reference to a Material Adverse Effect or materiality shall be true and
     correct, and the representations and warranties of Sense8 that are not so

     not, individually or in the aggregate, constitute a Material Adverse
     Effect, in each case as of the date of the Original Agreement (except to
     the extent such representations and warranties speak as of an earlier
     date). EAI shall have received a certificate signed on behalf of Sense8 by
     the President, to the foregoing effect.
 
          (b) Performance of Obligations of Sense8.  Sense8 shall have performed
     in all material respects all obligations required to be performed by it
     under this Agreement at or prior to the Closing Date other than obligations
     which, individually or in the aggregate, if not performed, would not have a
     Material Adverse Effect, and EAI shall have received a certificate signed
     on behalf of Sense8 by the Chairman of the Board and the President to such
     effect.
 
          (c) Dissenters Rights.  Holders of not more than twenty percent (20%)
     of the outstanding Sense8 Stock shall have validly exercised their
     "dissenters rights" pursuant to the CGCL.

prior to the Effective Time of the following conditions:
 
          (a) Representations and Warranties.  The representations and
     warranties of EAI set forth in this Agreement that are qualified with a
     reference to materiality shall be true and correct, and the representations
     and warranties of EAI that are not so qualified shall be true and correct
     in all material respects, in each case, as of the date of the Original
     Agreement (except to the extent such representations and warranties speak

     been declared effective under the Securities Act and shall not be the
     subject of any stop order or proceeding by the SEC seeking a stop order.
 
                                 ARTICLE VIII.
 
                           TERMINATION AND AMENDMENT
 
     8.1. Termination.  This Agreement may be terminated at any time prior to
the Effective Time, whether before or after approval of the Merger by the
shareholders of Sense8:
 
          (a) by mutual consent of Sense8 and EAI in a written instrument, if
     the Board of Directors of each so determines by a vote of a majority of the
     members of its entire Board;
 
                                      A-20
<PAGE>   96
 
          (b) by either the Board of Directors of Sense8 or the Board of
     Directors of EAI if any Governmental Authority which must grant a Requisite
     Regulatory Approval has denied approval of the Merger, or any Governmental
     Authority of competent jurisdiction shall have issued an order permanently
     enjoining or otherwise prohibiting the consummation of the transactions
     contemplated by this Agreement;
 
          (c)  by either the Board of Directors of Sense8 or the Board of
     Directors of EAI (provided that the terminating party is not then in
     material breach of any representation, warranty, covenant or other
     agreement contained herein) if (x) there shall have been a material breach
     of any of the representations or warranties or any of the covenants or
     agreements set forth in this Agreement on the part of the other party,
     which breach is not cured within 30 days following written notice to the
     party committing such breach, or which breach, by its nature or timing,
     cannot be cured prior to June 30, 1998, (y) the Closing shall not have
     occurred on or before June 30, 1998; provided, however, that neither Board
     of Directors shall be entitled to terminate the Agreement pursuant to this
     clause (y) if the reason the Closing has not occurred by such date is
     because any Governmental Authority which must grant a Requisite Regulatory
     Approval has failed to act, the S-4 shall have been filed but shall not yet
     have been declared effective, the Sense8 shareholder meeting shall not have
     occurred in accordance with the requirements of the CGCL and the DGCL or
     some similar event beyond the control of both parties shall not have
     occurred by such date, or (z) the Closing shall not have occurred on or
     before August 31, 1998; or
 
          (d) by the Board of Directors of Sense8 (after consulting with its
     legal counsel), if such action is required for the Board of Directors to
     comply with its fiduciary duties to Sense8 and its shareholders as
     contemplated in Section 6.6 hereof; provided, however, if such action is
     taken by Sense8, then (i) within 2 days of such termination Sense8 shall
     reimburse EAI for its out-of-pocket expenses incurred in connection with
     the transactions contemplated by this Agreement; and (ii) if Sense8 shall
     consummate any transaction pursuant to a Takeover Proposal (x) within 12
     months following April 11, 1998, or (y) pursuant to a definitive agreement
     executed by Sense8 during such 12-month period, Sense8 shall also promptly
     pay to EAI $300,000 upon the closing of such transaction;
 
provided, however, if the Sense8 shareholder meeting shall have occurred and the
Sense8 shareholders shall have voted with respect to approval of the Merger and
the requisite vote necessary to approve the Merger shall not have been received,
then this Agreement shall automatically be terminated as of the date of such
Sense8 shareholder meeting without further action of any of the parties hereto
and within 2 days of such termination Sense8 pay to EAI $75,000 as reimbursement
for EAI's out-of-pocket expenses incurred in connection with the transactions
contemplated by this Agreement (for which EAI shall not be required to account).
 
     8.2. Effect of Termination.  In the event of termination of this Agreement
by either Sense8 or EAI as provided in Section 8.1, this Agreement shall
forthwith become void and have no effect, and none of Sense8, EAI, Sub or any of
their directors or officers shall have any liability of any nature whatsoever
hereunder, or in connection with the transactions contemplated hereby, except
that (i) Sections 8.1(d) and 9.1, the final proviso clause of Section 8.1 and
this Section 8.2 shall survive any termination of this Agreement, and (ii)
notwithstanding anything to the contrary contained in this Agreement, neither
Sense8 nor EAI shall be relieved or released from any liabilities or damages
arising out of its willful breach of any provision of this Agreement.
 
     8.3. Amendment; Extension; Waiver.  At any time prior to the Effective
Time, the parties hereto, by action taken or authorized by their respective
Board of Directors, may, to the extent legally allowed, (i) amend any term or
provision of this Agreement, (ii) extend the time for the performance of any of
the obligations or other acts of the parties hereto, (iii) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto and (iv) waive compliance with any of the
agreements or conditions contained herein; provided, however, that after any
approval of the transactions contemplated by this Agreement by the shareholders
of Sense8, there may not be, without further approval of such shareholders, any
amendment, extension or waiver of this Agreement which reduces the amount or
changes the form of the consideration to be delivered to the holders of Sense8
Stock hereunder other than as contemplated by this Agreement. Any agreement on
the part of a party hereto to any such
 
                                      A-21
<PAGE>   97
 
amendment, extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party, but such amendment, extension or
waiver or failure to insist on strict compliance with any obligation, covenant,
agreement or condition in this Agreement shall not operate as a waiver of, or
estoppel with respect to, any subsequent or other failure.

costs and expenses will be paid by EAI), all costs and expenses incurred in

consummated, EAI, as the Surviving Corporation, shall pay Sense8's costs and
expenses.

     9.3. Interpretation.  When a reference is made in this Agreement to
Sections, Schedules or Exhibits, such reference shall be to a Section of or
Schedule or Exhibit to this Agreement unless otherwise indicated. The table of
contents and headings contained in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement. Whenever the words "include," "includes" or "including" are used in
this Agreement, they shall be deemed to be followed by the words "without
limitation." No provision of this Agreement shall be construed to require EAI,
Sub, Sense8 or any of their respective affiliates to take any action which would
violate any applicable law, rule or regulation.
 
     9.4. Counterparts.  This Agreement may be executed in counterparts, all of
which shall be considered one and the same agreement.
 
     9.5. Entire Agreement.  This Agreement (including the Disclosure Schedule,
the Exhibits, and the Confidential Disclosure Agreement dated as of February 20,
1998) constitutes the entire agreement of the parties and supersedes all prior
agreements and understandings, both written and oral, between the parties with
respect to the subject matter hereof.
 
     9.6. Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of California, without regard to any
applicable conflicts of law which would result in the application of any other
law.
 
     9.7. Severability.  Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable.
 
     9.8. Publicity.  Except as otherwise required by applicable law or the
rules of the NNM, neither Sense8 nor EAI shall, or shall permit any of their
respective affiliates to, issue or cause the publication of any press release or
other public announcement with respect to, or otherwise make any public
statement concerning, the transactions contemplated by this Agreement without
the prior consent of the other party, which consent shall not be unreasonably
withheld.
 
     9.9. Assignment; Third Party Beneficiaries.  Neither this Agreement nor any
of the rights, interests or obligations set forth herein shall be assigned by
either of the parties (whether by operation of law or otherwise) without the
prior written consent of the other party. Subject to the preceding sentence,
this Agreement shall be binding upon, inure to the benefit of, and be
enforceable by, the parties and their respective successors and assigns. This
Agreement (including the Disclosure Schedule, Exhibits, documents and
instruments referred to herein) is not intended to confer upon any person other
than the parties hereto any rights or remedies hereunder.
 
     9.10. Knowledge and Awareness.  As used in this Agreement, "knowledge" or
"awareness" of any entity means the actual knowledge or awareness of such
entity's officers and other persons exercising supervisory authority, and such
knowledge or awareness as such entity's officers and other persons exercising
supervisory authority should have had after reasonable investigation. Whenever
the term "knowledge" or "awareness" is used to refer to the "knowledge" or
"awareness" of Sense8, such term shall include the "knowledge" or "awareness" of
the directors, officers and other persons exercising supervisory authority over
Sense8 and the shareholders of Sense8 who are active in the business of Sense8.
 
     9.11. Construction.  The parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the parties and no presumptions or burden of proof
shall arise favoring or disfavoring any party by virtue of the authorship of any
of the provisions of this Agreement. Any reference to any Federal, state,
county, local or foreign law or statute shall be deemed also to refer to all
rules and regulations promulgated thereunder, unless the context requires
otherwise.

     9.12. Tax Free Reorganization.  In the event that either EAI or Sense8
becomes aware of any provisions of this Agreement which would prevent the Merger
from qualifying as a reorganization within the meaning of Section 368 of the
Code, such parties shall negotiate in good faith with a view toward amending
this Agreement in a manner which would permit the Merger to qualify as such a
reorganization, as applicable.
 
     IN WITNESS WHEREOF, EAI, Sub and Sense8 have caused this AMENDED AND
RESTATED AGREEMENT AND PLAN OF MERGER to be executed by their respective
officers thereunto duly authorized as of the date first above written.

                     FORM OF LEGAL OPINION TO BE DELIVERED
                        BY COUNSEL TO SENSE8 CORPORATION
 
     The legal opinion of Brobeck, Phleger & Harrison LLP, counsel to Sense8
Corporation ("Sense8"), shall be to the effect that:
 
     1. Sense8 has been duly incorporated and is validly existing and in good
standing under the laws of the State of California. Sense8 has the corporate
power and authority to own or lease all of its properties and assets and to
carry on its business as it is now being conducted. Sense8 is duly qualified to
do business and is in good standing as a foreign corporation under the laws of
each jurisdiction in which the nature of the business conducted by it or the
character or location of the properties and assets owned or leased by it makes
such qualification necessary.
 
     2. The number of shares of authorized, issued and outstanding capital stock
of Sense8 are each correctly set forth in Section 3.2 of the Merger Agreement.
All of the issued and outstanding shares of Sense8 Stock have been duly
authorized and validly issued and are fully paid, nonassessable and free of
statutory preemptive rights. To the knowledge of such counsel, other than the
Sense8 Options, the Sense8 Warrants and the Sense8 Convertible Notes listed in
Section 3.2 of the Disclosure Schedule and subject to preemptive rights as set
forth in Sense8's By-laws, Sense8 does not have and is not bound by any
outstanding subscriptions, options, convertible securities, warrants, calls,
commitments or agreements of any character calling for the purchase or issuance
of any shares of its capital stock. Each of the Sense8 Warrants and each of the
Sense8 Options (other than Sense8 Options held by persons who have consented in
writing to have such Sense8 Options convert into options to acquire EAI Common
Stock) shall, under their terms, automatically convert as a result of the Merger
into warrants or options to acquire EAI Common Stock as provided in Article II
of the Merger Agreement.
 
     3. Sense8 has the corporate power and authority to execute and deliver the
Merger Agreement and to consummate the transactions contemplated thereby. The
execution and delivery of the Merger Agreement and the consummation of the
transactions contemplated thereby have been duly and validly approved by the
Board of Directors and shareholders of Sense8. No other corporate proceedings on
the part of Sense8 are necessary to approve the Merger Agreement or to
consummate the transactions contemplated thereby. The Merger Agreement has been
duly and validly executed and delivered by Sense8 and constitutes a valid and
binding obligation of Sense8, enforceable against Sense8 in accordance with its
terms, subject to the qualifications that enforcement may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, or other similar
laws affecting creditors' rights generally and by general principles of equity
(regardless of whether enforcement is sought in equity or in law).
 
     4. The execution and delivery of the Merger Agreement by Sense8, the
consummation by Sense8 of the transactions contemplated thereby, and the
compliance by Sense8 with the terms or provisions thereof, will not (i) violate
any provision of the Articles of Incorporation or By-Laws of Sense8, (ii)
constitute a violation of any Applicable Contracts, (iii) cause the creation of
any security interest or lien upon any of the property of Sense8 pursuant to any
Applicable Contract, (iv) contravene any provision of any Applicable Law, or
(v) contravene any Applicable Order of any Governmental Authority against
Sense8.
 
     Reference to (i) "Applicable Laws" shall mean the Delaware General
Corporation Law and those laws, rules and regulations of the State of California
and of the United States of America which, in such counsel's experience, are
normally applicable to transactions of the type contemplated by the Merger
Agreement; (ii) "Governmental Authorities" shall mean any Delaware, California,
federal executive, legislative, judicial, administrative or regulatory body,
(iii) "Applicable Orders" shall mean those orders or decrees of Governmental
Authorities identified on a schedule attached to such opinion which are the only
orders or decrees known to such counsel to be binding on Sense8; and (iv)
"Applicable Contracts" shall mean those agreements or instruments set forth on
Section 3.13 of the Disclosure Schedule to the Merger Agreement.
 
                                      A-25

     5. Except for (i) the filing of the Agreement of Merger with the California
Secretary of State pursuant to the California General Corporation Law and the
Certificate of Merger with the Delaware Secretary of State pursuant to the
Delaware General Corporation Law, (ii) the approval of the Merger Agreement by
the requisite vote of the holders of Sense8 Stock, and (iii) the filing with the
SEC and declaration of effectiveness of the S-4, all of which filings,
expirations, approvals and declarations have been made, occurred or obtained, no
Consent of any Governmental Authority is necessary in connection with the
execution and delivery by Sense8 of the Merger Agreement and the consummation by
Sense8 of the Merger and the other transactions contemplated thereby.
 
     6. There are no actions, suits, proceedings, claims or investigations
pending or, to the knowledge of counsel after due inquiry, threatened against or
affecting Sense8 at law or in equity or before any Governmental Authority or
challenging the validity or propriety of the transactions contemplated by the
Merger Agreement.

                     FORM OF LEGAL OPINION TO BE DELIVERED
               BY GENERAL COUNSEL OF ENGINEERING ANIMATION, INC.
 
     The legal opinion of Jamie A. Wade, General Counsel of Engineering
Animation, Inc. ("EAI"), may assume that the laws of California are the same as
the laws of Iowa and shall be to the effect that:
 
     1. EAI is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware. EAI has the corporate power
and authority to own or lease all of its properties and assets and to carry on
its business as it is now being conducted.
 
     2. The authorized capital stock of EAI consists of 20,000,000 shares of EAI
Common Stock and 20,000,000 shares of preferred stock, $.01 par value per share.
All of the issued and outstanding shares of EAI Common Stock have been duly
authorized and validly issued and are fully paid, nonassessable and free of
statutory preemptive rights. The shares of EAI Common Stock to be issued
pursuant to the Merger have been duly authorized and, at the Effective Time upon
issuance pursuant to the Merger Agreement, all such shares will be validly
issued, fully paid, nonassessable and free of statutory preemptive rights.
 
     3. EAI has the corporate power and authority to execute and deliver the
Merger Agreement and to consummate the transactions contemplated thereby. The
execution and delivery of the Merger Agreement and the consummation of the
transactions contemplated thereby have been duly and validly approved by the
Board of Directors of EAI. No other corporate proceedings on the part of EAI are
necessary to approve the Merger Agreement or to consummate the transactions
contemplated thereby. The Merger Agreement has been duly and validly executed
and delivered by EAI and constitutes a valid and binding obligation of EAI,
enforceable against EAI in accordance with its terms, except to the extent that
enforcement may be limited by applicable bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium or similar laws of general application
relating to or affecting the enforcement of the rights of creditors or by
equitable principles regardless of whether enforcement is sought in a proceeding
in equity or at law. No opinion is expressed as to the validity or
enforceability of any provision regarding choice of California law to govern the
Merger Agreement.
 
     4. The execution and delivery of the Merger Agreement by EAI, the
consummation by EAI of the transactions contemplated thereby, and the compliance
by EAI with the terms or provisions thereof, will not (i) violate any provision
of the Certificate of Incorporation or By-Laws of EAI, (ii) violate the Delaware
General Corporation Law, the California General Corporation Law or any federal
law, rule or regulation that to the knowledge of such counsel is applicable to
transactions of the type contemplated by the Merger Agreement, (iii) contravene
any order or decree of any federal, governmental authority known by such counsel
to be applicable to EAI, or (iv) constitute a violation of, or cause the
creation of any lien pursuant to, any material license, lease, contract,
agreement or other instrument or obligation to which EAI or any of its
subsidiaries is a party and which is filed as an exhibit to any filings or
reports with the SEC. Notwithstanding the preceding sentence, no opinion is
expressed as to whether the execution and delivery of the Merger Agreement by
EAI, the consummation by EAI of the transactions contemplated thereby or the
compliance by EAI with the terms and provisions thereof will constitute a breach
of, or constitute a default under, any covenant or provision with respect to
financial ratios or tests or any aspect of the financial condition or results of
operations of EAI contained in any agreement to which EAI is a party.
 
     5. Except for (i) the filing of the Agreement of Merger with the California
Secretary of State pursuant to the California General Corporation Law and the
Certificate of Merger with the Delaware Secretary of State pursuant to the
Delaware General Corporation Law, (ii) the filing with the SEC and declaration
of effectiveness of the S-4, (iii) such filings and approvals as are required to
be made or obtained under the securities or "Blue Sky" laws of various states in
connection with the issuance of the shares of EAI Common Stock pursuant to this
Agreement, and (iv) the filings and authorizations necessary to list the shares
of EAI Common Stock issued pursuant to the Merger Agreement on the NNM, all of
which filings, expirations, approvals and declarations have been made, occurred
or obtained, no Consents from any federal, California or Delaware governmental
authority are necessary in connection with the execution and delivery by EAI of
the Merger Agreement and the consummation by EAI of the Merger and the other
transactions contemplated by the Merger Agreement.

                                   APPENDIX B
 
            CALIFORNIA GENERAL CORPORATION LAW -- DISSENTERS' RIGHTS
 
1300 [SHORT FORM MERGER; PURCHASE OF SHARES AT FAIR MARKET VALUE;
"DISSENTING SHARES" AND DISSENTING SHAREHOLDER].
 
     (a) If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision (b). The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.
 
     (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:
 
          (1) Which were not immediately prior to the reorganization or
     short-form merger either (A) listed on any national securities exchange
     certified by the Commissioner of Corporations under subdivision (o) of
     Section 25100 or (B) listed on the list of OTC margin stocks issued by the
     Board of Governors of the Federal Reserve System, and the notice of meeting
     of shareholders to act upon the reorganization summarizes this section and
     Sections 1301, 1302, 1303 and 1304; provided, however, that this provision
     does not apply to any shares with respect to which there exists any
     restriction on transfer imposed by the corporation or by any law or
     regulation; and provided, further, that this provision does not apply to
     any class of shares described in subparagraph (A) or (B) if demands for
     payment are filed with respect to 5 percent or more of the outstanding
     shares of that class.
 
          (2) Which were outstanding on the date for the determination of
     shareholders entitled to vote on the reorganization and (A) were not voted
     in favor of the reorganization or, (B) if described in subparagraph (A) or
     (B) of paragraph (1) (without regard to the provisos in that paragraph),
     were voted against the reorganization, or which were held of record on the
     effective date of a short-form merger; provided, however, that subparagraph
     (A) rather than subparagraph (B) of this paragraph applies in any case
     where the approval required by Section 1201 is sought by written consent
     rather than at a meeting.
 
          (3) Which the dissenting shareholder has demanded that the corporation
     purchase at their fair market value, in accordance with Section 1301.
 
          (4) Which the dissenting shareholder has submitted for endorsement, in
     accordance with Section 1302.
 
     (c) As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.
 
1301 [DISSENTERS' RIGHTS; DEMAND ON CORPORATION FOR PURCHASE OF SHARES].
 
     (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise the shareholder's right under such sections.
The statement of price constitutes an offer by the corporation to purchase at
the price stated any
 
                                       B-1
<PAGE>   105
 
dissenting shares as defined in subdivision (b) of Section 1300, unless they
lose their status as dissenting shares under Section 1309.
 
     (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.
 
     (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.
 
1302 [DISSENTING SHARES, STAMPING OR ENDORSING].
 
     Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.
 
1303 [DISSENTING SHAREHOLDER ENTITLED TO AGREED PRICE
WITH INTEREST; TIME OF PAYMENT].
 
     (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.
 
     (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.
 
1304 [DISSENTERS' ACTIONS; JOINDER; CONSOLIDATION; APPOINTMENT OF APPRAISERS].
 
     (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market values of the
shares, then the shareholder demanding purchase of such shares as dissenting
shares of any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares of the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.
                                       B-2
<PAGE>   106
 
     (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.
 
     (c) On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     EAI's Certificate of Incorporation and By-laws provide that EAI shall,
subject to certain limitations, indemnify its directors and officers against
expenses (including attorneys' fees, judgments, fines and certain settlements)
actually and reasonably incurred by them in connection with any suit or
proceeding to which they are a party so long as they acted in good faith and in
a manner reasonably believed to be in or not opposed to the best interests of
the corporation, and, with respect to a criminal action or proceeding, so long
as they had no reasonable cause to believe their conduct to have been unlawful.
 
     Section 102 of the Delaware General Corporation Law permits a Delaware
corporation to include in its certificate of incorporation a provision
eliminating or limiting a director's liability to a corporation or its
stockholders for monetary damages for breaches of fiduciary duty. The enabling
statute provides, however, that liability for breaches of the duty of loyalty,
acts or omissions not in good faith or involving intentional misconduct, or
knowing violation of the law, and the unlawful purchase or redemption of stock
or payment of unlawful dividends or the receipt of improper personal benefits
cannot be eliminated or limited in this manner. EAI's Certificate of
Incorporation includes a provision that eliminates, to the fullest extent
permitted, director liability for monetary damages for breaches of fiduciary
duty.

ITEM 22.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
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.
 
                                      II-1
<PAGE>   108
 
     The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.
 
     The undersigned registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is part of this registration statement, by any person or party
who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer
undertakes that such reoffering prospectus will contain the information called
for by the applicable registration form with respect to reofferings by persons
who may be deemed underwriters, in addition to the information called for by the
other Items of the applicable form.
 
     The registrant undertakes that every prospectus (i) that is filed pursuant
to the paragraph immediately preceding, or (ii) that purports to meet the
requirements of section 10(a)(3) of the Act and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, 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.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of
such issue.
 
     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in the documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
