ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

Acquisition of Sense8 Corporation

        On June 17, 1998, Engineering Animation, Inc. (the "Company") completed
the acquisition of Sense8 Corporation ("Sense8"), a privately held developer
and distributor of interactive, real-time 3D and virtual reality tools and
applications.  The Company acquired Sense8 pursuant to a merger of Sense8 with
and into the Company (the "Merger").  In connection with the acquisition, the
Company issued common stock, $0.01 per share par value ("Common Stock") to
Sense8 shareholders with a value of approximately $7,000,000, based on the stock
price of $42.61725 per share, as provided in the Amended and Restated Agreement
and Plan of Merger ("the "Merger Agreement") among the Company, Sense8 and
EAICA, Inc., a wholly owned subsidiary of the Company.  The Company also
assumed approximately $1,300,000 in liabilities of Sense8.  The shareholders of
Sense8 received approximately 0.084655 of a share of Common Stock for each
share of Sense8 common stock, 0.244215 of a share of Common Stock for each
share of Sense8 Series A Preferred Stock and 0.499041 of a share of Common
Stock for each share of Sense8 Series B Preferred Stock held at the 
consummation of the transaction.  Each outstanding option or warrant to acquire
common stock of Sense8 automatically converted into an option or warrant to
acquire the same number of shares of Common Stock as the shares underlying such
Sense8 option or warrant would have been exchangeable for had such Sense8
option or warrant been exercised in full immediately prior to the consummation
of the acquisition.  The acquisition of Sense8 by the Company will be treated
as a purchase for accounting and financial reporting purposes.

                       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.

                             Sense 8 Corporation
                  Notes to Consolidated Financial Statements

              (Unaudited with respect to March 31, 1998 and the
              three-month periods ended March 31, 1997 and 1998)
    
 
                   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-11
<PAGE>   15
           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 19 percent and 10 percent of total accounts receivable
at December 31, 1996 and 1997, respectively.
    
 
SALES TO SIGNIFICANT CUSTOMERS
 
   
      During the year ended December 31, 1996, sales to two customers 
represented 21 percent and 15 percent of net revenues, respectively. During     
the year ended December 31, 1997, sales to one customer represented 12 percent
of net revenues.
    
 
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, 1996 and 1997, 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;

<PAGE>   16
           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.

   
INTERIM FINANCIAL INFORMATION (UNAUDITED)

     The accompanying interim consolidated financial statements as of March 31,
1998 and for the three months ended March 31, 1997 and 1998 are unaudited. The
unaudited interim financial statements have been prepared on the same basis as
the annual financial statements and, in the opinion of management, reflect all
adjustments, which include only normal recurring adjustments, necessary to 
present fairly the results of the Company's operations and its cash flows for 
the three months ended March 31, 1997 and 1998. The financial data and other 
information disclosed in these notes to consolidated financial statements 
related to these periods are unaudited. The results for the three months ended
March 31, 1998, are not necessarily indicative of the results expected for the 
year ending December 31, 1998.      
    
 
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.

     During the years ended December 31, 1996 and 1997, the Company purchased
hardware inventory at estimated market prices from a shareholder totaling 
$59,000 and $7,000, respectively.
     
     See Note 5 for other related party transactions.
 
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

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

     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

</TABLE>
 
     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, 1996 and 1997, 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:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     Under SFAS 123, the fair value of each option grant is estimated on the
date of grant using the Black-Scholes option-pricing model with the following
weighted-average assumptions used for grants in 1996 and 1997.

reported net income (loss) for future years.
 
401(K) PLAN
 
   
     During the year ended December 31, 1996, the Company established a defined
contribution 401(k) Plan for substantially all of its employees. Under the
401(k) Plan, employees may contribute up to 20 percent of their gross wages. The
Company will, at its discretion, match a percentage of the employee
contribution. For the years ended December 31, 1996 and 1997, the Company
elected to not contribute a Company match to the 401(k) Plan.

               AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER
 
     AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER, DATED AS OF APRIL 30,
1998 (THE "AGREEMENT"), BY AND AMONG ENGINEERING ANIMATION, INC., A DELAWARE

SUBSIDIARY OF EAI ("SUB"), AND SENSE8 CORPORATION, A CALIFORNIA CORPORATION
("SENSE8").
 
     WHEREAS, the Boards of Directors of EAI and Sense8 have determined that it
is in the best interests of their respective companies and the stockholders of
EAI and the shareholders of Sense8 to consummate the business combination
provided for in this Agreement;
 
     WHEREAS, on April 11, 1998, EAI, Sub and Sense8 entered into an Agreement
and Plan of Merger (the "Original Agreement") pursuant to which Sub, subject to
the terms and conditions set forth therein, was to merge with and into Sense8
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
merger of Sense8 with and directly into EAI (the "Merger") and thus have amended
and restated the Original Agreement by entering into this Agreement;
 
     WHEREAS, EAI and Sense8 entered into an Interim Management Agreement
concurrent with the Original Agreement;
 
     WHEREAS, the parties desire to make certain representations, warranties and
agreements in connection with the Merger and to establish certain conditions to
the Merger.
 
     NOW, THEREFORE, in consideration of the mutual covenants, representations,
warranties and agreements contained herein, the parties agree as follows:
 
                                   ARTICLE I.

General Corporation Law (the "DGCL"), at the Effective Time (as hereinafter
defined), Sense8 shall merge with and into EAI. EAI shall be the surviving

Corporation"), and shall continue its corporate existence under the laws of the
State of Delaware. Upon consummation of the Merger, the separate corporate
existence of Sense8 shall terminate.
 
     1.2. Closing.  Subject to the terms and conditions of this Agreement, the
closing of the Merger (the "Closing") will take place, at the offices of
Gardner, Carton & Douglas, 321 North Clark Street, Chicago, Illinois, as soon as
possible following the meeting of the shareholders of Sense8 at which the Merger
is approved (the "Shareholder Meeting"), but in any event not later than two
business days after the satisfaction or waiver of the latest to occur of the
conditions set forth in Article VII, unless extended by mutual agreement of the
parties (the "Closing Date").
 
     1.3. Effective Time.  Subject to the provisions of this Agreement, the
Agreement of Merger and the Certificate of Merger, the parties hereto shall
cause the Merger to be consummated by filing a properly executed Agreement of
Merger with the California Secretary of State in accordance with the CGCL and a
properly executed Certificate of Merger with the Delaware Secretary of State in
accordance with the DGCL (the time of such filings being the "Effective Time")
on the Closing Date.
 
     1.4. Effects of the Merger.  At and after the Effective Time, the Merger
shall have the effects set forth in the CGCL and the DGCL.
<PAGE>   7
 
     1.5. Certificate of Incorporation and By-Laws.  Subject to the terms and

By-Laws of the Surviving Corporation until thereafter amended in accordance with
applicable law.

Surviving Corporation, unless and until thereafter changed in accordance with
the DGCL and the Surviving Corporation's Certificate of Incorporation and
By-Laws.
 
     1.7. Tax Consequences.  EAI and Sense8 intend that the Merger shall
constitute a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "Code"), and that this Agreement shall
constitute a "plan of reorganization" for the purposes of Section 368 of the
Code.
 
                                  ARTICLE II.

"Total Merger Consideration") shall equal (i) $6,793,089 minus (ii) any legal

relate to the Merger and which are not reflected on the March 31, 1998
consolidated balance sheet of Sense8, attached hereto as Exhibit C, plus (iii)
the principal amount and converted interest of any Sense8 Convertible Notes
which are converted prior to the Effective Time.
 
     2.3. Conversion of Sense8 Stock.  At the Effective Time, by virtue of the
Merger and without any action on the part of EAI, Sense8 or any shareholder of
Sense8:
 
          (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.
 
                                       A-3
<PAGE>   9
 
          (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.

<PAGE>   10
 
     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

Sense8 has the corporate power and authority to own or lease all of its

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,
(i) any shares of outstanding capital stock or securities convertible into
capital stock of any other corporation or (ii) any participating interest in any

     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 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

     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.

     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
     as to the adjusted tax basis of its shareholders in their Sense8 Stock.

                              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.

     7.2. Conditions to Obligations of EAI.  The obligation of EAI to effect the
Merger is also subject to the satisfaction or waiver by EAI at or prior to the
Effective Time of the following conditions:
 
          (a) Representations and Warranties.  The representations and
     warranties of Sense8 set forth in this Agreement that are qualified with
     reference to a Material Adverse Effect or materiality shall be true and
     correct, and the representations and warranties of Sense8 that are not so
     qualified shall be true and correct except to the extent such failure does
     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.
 
          (d) Sense8 Options.  Each holder of a Sense8 Option which does not
     automatically convert in the Merger into an option to acquire EAI Common
     Stock shall have consented to the assumption by EAI of such Sense8 Option
     as contemplated by Section 2.6 pursuant to a written agreement or
     instrument signed by such holder.
 
          (e) Legal Opinion; Closing Certificates.  EAI shall have received from
     Brobeck, Phleger & Harrison LLP, counsel to Sense8, an opinion
     substantially in the form attached as Exhibit A, together with such
     customary closing documents and certificates as EAI or its counsel shall
     reasonably request.
 
     7.3. Conditions to Obligations of Sense8.  The obligation of Sense8 to
effect the Merger is also subject to the satisfaction or waiver by Sense8 at or
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
     as of an earlier date). Sense8 shall have received a certificate signed on
     behalf of EAI by the Chief Executive Officer or the Chief Financial Officer
     of EAI to the foregoing effect.
 
          (b) Performance of Obligations of EAI.  EAI 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, and Sense8 shall have
     received a certificate signed on behalf of EAI by the Chief Executive
     Officer or the Chief Financial Officer of EAI to such effect.
 
          (c) Legal Opinion; Closing Certificates.  Sense8 shall have received
     from Jamie A. Wade, General Counsel of EAI, an opinion substantially in the
     form attached as Exhibit B together with such customary closing documents
     and certificates as Sense8 or its counsel shall reasonably request.
 
          (d) Registration Statement.  The Registration Statement shall have
     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>   26
 
          (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>   27
 
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.
 
                                  ARTICLE IX.
 
                               GENERAL PROVISIONS

clause of Section 8.1 and any costs or expenses incurred with respect to the
December 31, 1997 audit by Price Waterhouse of Sense8's books and records (which
costs and expenses will be paid by EAI), all costs and expenses incurred in
connection with this Agreement and the transactions contemplated hereby shall be
paid by the party incurring such expense; provided, however, if the Merger is
consummated, EAI, as the Surviving Corporation, shall pay Sense8's costs and
expenses.
 
     9.2. Notices.  All notices and other required communications hereunder

     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.

<PAGE>   29
 
     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.
