ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

ACQUISITION OF CIMTECH, INC.

     On November 26, 1997, Engineering Animation, Inc. (the "Company") 
completed the acquisition of Cimtech, Inc. ("Cimtech"), a privately held 
developer of factory layout software for approximately $6,000,000 in newly 
issued common stock of the Company, $0.01 per share par value ("Common 
Stock"). The Company acquired Cimtech pursuant to a merger of COHO, Inc. 
("COHO"), a wholly-owned subsidiary of the Company, with and into Cimtech.  
Pursuant to the terms of the Amended and Restated Agreement and Plan of 
Merger among the Company, Cimtech and COHO, the shareholders of Cimtech 
received approximately 0.12937 of a share of Common Stock for each share of 
Cimtech common stock held at the consummation of the transaction.  In 
addition, each holder of an option to acquire common stock of Cimtech agreed 
to exchange such Cimtech option for an option to acquire the same number of 
shares of Common Stock as the shares underlying such Cimtech option would 
have been exchangeable for had such Cimtech option been exercised in full 
immediately prior to the consummation of the acquisition.  The acquisition of 
Cimtech by the Company will be treated as a pooling of interests for 
accounting and financial reporting purposes.  The Company expects to continue 
to operate the business previously operated by Cimtech.

ACQUISITION OF TECHNOLOGY COMPANY VENTURES, L.L.C. AND ROSETTA 
TECHNOLOGIES, INC.

     On November 25, 1997, Engineering Animation, Inc. (the "Company") 
completed the acquisition of Rosetta Technologies, Inc. ("Rosetta"), a 
privately held provider of interactive product data access and viewing 
solutions, for approximately $25,550,000 in Common Stock.  The Company 
acquired Rosetta through two separate transactions.  In the first 
transaction, Technology Company Ventures, L.L.C., an Oregon limited liability 
company and the holder of approximately 69% of the outstanding common stock 
of Rosetta ("Ventures"), merged with and into Shell Beaver, L.L.C., a wholly 
owned subsidiary of the Company ("Shell Beaver").  Pursuant to the terms of 
the Amended and Restated Agreement and Plan of Merger among the Company, 
Ventures and Shell Beaver, the members of Ventures received in exchange for 
their Ventures membership interests approximately 0.06215 of a share of 
Common Stock for each share of Rosetta common stock held by Ventures at the 
consummation of the transaction.  Miken, Inc. and JFJ Ventures, L.L.C. were 
the only members of Ventures at the time of the consummation of the 
acquisition.  The acquisition of Ventures by the Company will be treated as a 
pooling of interests for accounting and financial reporting purposes.  The 
sole asset of Ventures was common stock of Rosetta.

     In the second transaction, Transitory Beaver, Inc., a wholly-owned 
subsidiary of Shell Beaver ("Transitory Beaver"), merged with and into 
Rosetta, as a result of which Rosetta became an indirect, wholly-owned 
subsidiary of the Company.  Pursuant to the terms of the Amended and Restated 
Agreement and Plan of Merger among the Company, Rosetta and Transitory 
Beaver, the holders of Rosetta common stock (other than Shell Beaver) 
received approximately 0.06215 of a share of Common Stock for each share of 
Rosetta common stock held at the consummation of the transaction.  In 
addition, each option to acquire common stock of Rosetta was converted into 
an option to acquire the same number of shares of Common Stock as the shares 
underlying such Rosetta option would have been exchangeable for had such 

                                      1

Rosetta option been exercised in full immediately prior to the consummation 
of the acquisition.  The acquisition of Rosetta will be treated as a purchase 
for accounting and financial reporting purposes.  The Company expects to 
continue to operate the business previously operated by Rosetta.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The following unaudited pro forma condensed combined financial statements 
present the effects of the merger of  COHO with and into Cimtech (the 
"Cimtech Merger") and Ventures with and into Shell Beaver (the "Ventures 
Merger") as poolings of interests for accounting purposes and the merger of 
Transitory Beaver with and into Rosetta (the "Rosetta Merger") as a purchase 
for accounting purposes.  The $7.1 million purchase price of the Rosetta 
Merger was allocated as follows: $5.4 million to estimated preliminary 
in-process research and development, $636,000 to the elimination of the 
Rosetta minority interest and $1.1 million to goodwill.  The unaudited pro 
forma condensed combined financial statements are based upon the respective 
historical financial statements and notes thereto of the companies.

The unaudited pro forma condensed combined financial statements are presented 
for illustrative purposes only and are not necessarily indicative of the 
operating results or financial position that would have occurred if the 
Cimtech Merger, the Ventures Merger and the Rosetta Merger had each been 
consummated on the date indicated, nor are the unaudited pro forma condensed 
combined financial statements necessarily indicative of future operating 
results or financial position.

     NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

(a)  To reflect the recording of  estimated preliminary goodwill and the 
     resulting amortization over a five year period.  The purchase accounting 
     is subject to final appraisals being received.

(b)  To reflect the acquisition of the Rosetta minority interest.

(c)  To reflect the estimated write off of in-process research and development
     in connection with the acquisition of the Rosetta minority interest and the
     resulting income tax expense adjustment to reflect the combined tax 
     position.

(d)  To reflect the combined tax position as if the Cimtech Merger had occurred
     at the beginning of the earliest period presented. This adjustment is 
     based on the evaluation of a variety of factors including the combined 
     companies' statutory and state tax rates, and the elimination of the 
     valuation allowance for deferred tax assets of Cimtech.

(e)  To adjust the pro forma condensed combined balance sheet to reflect one-
     time merger-related charges which will be expensed at the time the 
     Ventures Merger and the Cimtech Merger are consummated as required under 
     the pooling-of-interests accounting method. These charges are presently 
     estimated to be approximately $1.2 million related to the Ventures Merger 
     and $700,000 related to the Cimtech Merger. Direct merger expenses include
     financial advisor fees, outside legal fees and accounting, and various 
     other costs and filing fees.

(f)  To reflect the conversion of a $351,000 convertible note into Rosetta
     common stock.

Board of Directors
Cimtech, Inc.

We have audited the accompanying balance sheet of Cimtech, Inc. as of 
December 31, 1996 and the related statements of operations, stockholders' 
equity and cash flows for the year then ended. These financial statements are 
the responsibility of the Company's management. Our responsibility is to 
express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audit provides a 
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of Cimtech, Inc. at December 
31, 1996 and the results of its operations and its cash flows for the year 
ended December 31, 1996, in conformity with generally accepted accounting 
principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BUSINESS AND ORGANIZATION

Cimtech, Inc. (the "Company") develops, produces and sells factory layout 
software for the CAD/CAM markets.

CASH EQUIVALENTS

For purposes of the statement of cash flows, the Company considers all highly 
liquid investments with a maturity of three months or less when purchased to 
be cash equivalents. Cash equivalents are carried at cost, which approximates 
market.

REVENUE RECOGNITION

Revenue from the sale of software is recognized at the time of shipment. 
Revenue is recognized from consulting contracts based upon labor and other 
costs incurred and progress to completion on contracts. Revenue from customer 
support services is deferred and recognized ratably over the period the 
customer support services are provided.

PROPERTY AND EQUIPMENT

Property and equipment is carried at cost. Depreciation and amortization of 
property and equipment is provided over the estimated useful lives of the 
assets, which range from five to seven years, on the straight-line method.

RESEARCH AND DEVELOPMENT COSTS

The Company capitalizes software development costs in accordance with 
Statement of Financial Accounting Standards No. 86, ACCOUNTING FOR THE COSTS 
OF COMPUTER SOFTWARE TO BE SOLD, LEASED OR OTHERWISE MARKETED. The 
capitalization of these costs begins when a product's technological 
feasibility has been established and ends when the product is available for 
general release to customers. Costs incurred by the Company between reaching 
technological feasibility and the point at which the product is ready for 
general release have been insignificant. All research and development costs 
have been expensed.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

INCOME TAXES

The Company accounts for income taxes using the liability method. Deferred 
income taxes are provided for temporary differences between the financial 
reporting and tax basis of assets and liabilities.

EARNINGS PER SHARE

Per share earnings are based on the weighted average number of shares of 
common stock and common stock equivalents outstanding. The dilutive effect of 
outstanding stock options was determined based upon the treasury stock method.

In February 1997, the Financial Accounting Standards Board issued Statement 
No. 128, EARNINGS PER SHARE, which is required to be adopted on December 31, 
1997. At that time, the Company will be required to change the method 
currently used to compute earnings per share and to restate all prior 
periods. Under the new requirements for calculating basic earnings per share, 
the dilutive effect of stock options will be excluded. The impact of adopting 
Statement No. 128 is not expected to be material.

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 amounts reported in the financial statements and accompanying 
notes. Actual results could differ from those estimates.

STOCK-BASED COMPENSATION

The Company has adopted the disclosure-only provisions of Statement of 
Financial Accounting Standards No. 123, ACCOUNTING FOR STOCK-BASED 
COMPENSATION, but applies Accounting Principles Board Opinion No. 25 (APB 25) 
and related interpretations in accounting for its plans. Under APB 25, when 
the exercise price of employee stock options equals the market price of the 
underlying stock on the date of grant, no compensation expense is recognized.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

UNAUDITED FINANCIAL INFORMATION

The accompanying financial statements as of December 31, 1995, June 30, 1997, 
and for the years ended December 31, 1995 and 1994, and the nine-month 
periods ended September 30, 1997 and 1996 are unaudited. In the opinion of 
the management of the Company, these financial statements reflect all 
adjustments, consisting only of normal and recurring adjustments necessary 
for a fair presentation of the financial statements. The results of 
operations for the nine-month period ended September 30, 1997 are not 
necessarily indicative of the results that may be expected for the full year 
ending December 31, 1997.

2. ROYALTY COMMITMENTS

The Company has received a total of $125,000 under a grant entered into in 
May 1988, and amended in June 1993, with the Iowa Product Development 
Corporation (the "IPDC"). Under terms of the grant, the Company is obligated 
to make royalty payments to the IPDC of 5% of all net revenues of sponsored 
prepackaged software and related services such as training, installation and 
maintenance for sponsored standard prepackaged software, royalty payments of 
25% of any license fees paid by any licensee to the Company with respect to 
any license of sponsored standard prepackaged software, plus an additional 5% 
royalty on any net sales of the sponsored standard prepackaged software by 
the licensee. The Company is obligated to repay the IPDC a total of $375,000 
as reimbursement for the amount received under the grant. At December 31, 
1996, the Company is obligated for $231,500 of additional royalty payments 
under this agreement.

In addition, during 1993 the Company granted the IPDC a warrant to purchase 
37,500 shares of the Company's common stock at $.15 per share. The warrant 
expires on December 31, 1998.

For the years ended December 31, 1996, 1995 and 1994, the Company incurred 
royalty expense of $46,750, $31,936 and $17,372, respectively.

December 31, 1996.

                                       F-17

4. STOCK OPTIONS

At December 31, 1996, the Company had outstanding stock options to purchase 
40,000 shares of common stock at exercise prices of $.10 to $1.00. The 
options expire during 1997 and 2007. At December 31, 1996, options to 
purchase 30,000 shares of common stock were exercisable at an exercise price 
of $.10 per share.

Pro forma information regarding net income is required by Statement No. 123, 
and has been determined as if the Company had accounted for its stock options 
under the fair value method of that Statement. The fair value of these 
options was estimated at the date of grant using the minimum value option 
pricing model with the following weighted-average assumptions for 1996: 
risk-free interest rate of 6.5% and a weighted average expected life of the 
option of five years.

The minimum value option valuation model was developed for use in estimating 
the fair value of traded options that have no vesting restrictions and are 
fully transferable. In addition, option valuation models require the input of 
highly subjective assumptions.

The effect of applying Statement 123's fair value method to the Company's 
stock-based awards results in net income that is not materially different 
than the amount reported for the year ended December 31, 1996.

During the initial phase-in period, the effects of applying Statement 123 for 
recognizing compensation cost may not be representative of the effects on 
reported net income or loss for future years because the options vest over 
several years and additional awards will be made in the future.

5.   INCOME TAXES

At December 31, 1996, the Company had a net operating loss carryforward (NOL) 
of approximately $850,000 which is available to offset taxable income through 
2011. For financial reporting purposes, a valuation allowance has been 
recorded to offset deferred tax assets that may not be realized.

To the Board of Managers and Members of
Technology Company Ventures, L.L.C.:

We have audited the accompanying consolidated balance sheet of Technology
Company Ventures, L.L.C. (an Oregon limited liability company) as of
December 31, 1996, and the related consolidated statements of operations,
member's equity and cash flows for the year then ended.  These financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audit.

We conducted our audit in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audit provides a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Technology Company
Ventures, L.L.C. as of December 31, 1996, and the results of its operations and
its cash flows for the year then ended, in conformity with generally accepted

                      TECHNOLOGY COMPANY VENTURES, L.L.C.
                     (An Oregon Limited Liability Company)

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

FORMATION OF TECHNOLOGY COMPANY VENTURES, L.L.C. AND BASIS OF PRESENTATION

On November 14, 1995, Technology Company Ventures, L.L.C. (TCV) was formed for
the purpose of acquiring a 68.5% interest in Rosetta Technologies, Inc. (RTI).
Since inception, TCV has had no other significant activities other than its
investment in RTI.  The accompanying financial statements represent the
consolidated financial statements of TCV and RTI, collectively, the Company.
The financial statements prior to the TCV acquisition are referred to as those
of the "predecessor."

TCV's initial capitalization included $2,249,000 of capital from JFJ Ventures,
L.L.C. (JFJ) and $1,000 from Miken, Inc. (Miken).  By virtue of the TCV
Operating Agreement, control over TCV is vested equally in JFJ and Miken.  JFJ
received a 75% liquidation and profits interest in TCV and Miken received a 25%
profits only member's interest in TCV for their capital contributions.  The
cash from this initial capitalization was utilized to purchase the 68.5%
interest in RTI.  As there was insignificant operating activity between
November 15, 1995 and November 30, 1995, the acquisition has been reflected in
the accompanying consolidated financial statements as if it occurred on
November 30, 1995.  The allocation of the purchase price was recorded as
follows:

    Cash paid                                            $  2,250,000
    Less: Acquired in-process research and development     (1,770,000)
             Fair value of net tangible assets acquired      (168,000)
                                                          -----------
             Goodwill                                      $  312,000
                                                          ===========

The Miken profits' interest, which consists of key executives of RTI, was
principally received for services rendered in connection with the acquisition
of the 68.5% interest in RTI.  Because there are no vesting provisions related
to the Miken member's interest, the $750,000 estimated value of the Miken
interest was recorded as a nonrecurring acquisition expense with a
corresponding increase to member's equity in the accompanying financial
statements.

Also in connection with this transaction, the Company recorded approximately
$1,770,000 of acquired in-process research and development and $312,000 of
goodwill which is being amortized ratably over a five-year period.  The amount
of the acquired in-process research and development was based on analysis of
the fair value of intangible assets acquired which indicated that a substantial
portion of the acquired intangible assets consisted of research and development
projects in-process.  The development of these projects had not reached
technological feasibility and the technology has no alternative future use.  In
accordance with generally accepted accounting principles, the acquired in-
process research and development was charged to expense and is included in the
accompanying consolidated statements of operations for the one-month ended
December 31, 1995.  The minority interest was carried forward in the purchase
price allocation at its underlying book value.

Unaudited pro forma net income for the twelve months ended December 31, 1995,
assuming the RTI acquisition had occurred on January 1, 1995, would have been
approximately $400,000, excluding the nonrecurring acquisition expenses.
Pro forma revenues were unchanged from historical revenues.

NATURE OF RTI BUSINESS

RTI was established in 1986 in Beaverton, Oregon, to develop, sell and service
software used in the manufacturing and engineering environment.  The Company's
software acts as an interactive data viewer that relays valuable information,
such as describing how products are engineered, manufactured, and supported
throughout a product's life cycle.  The Company's products are sold both
domestically and internationally.  During the years ended December 31, 1995
(unaudited) and 1996, 84% and 77% of revenues were from domestic customers and
16% and 23% from international customers, respectively.

                                       F-26

<PAGE>

Also, during the year ended December 31, 1994 (unaudited), three of the 
Company's customers accounted for 28%, 18% and 12% of total revenues.  During 
the year ended December 31, 1995(unaudited), one of the Company's customers 
accounted for 15% of total revenues.  There were no individual customers 
accounting for more than 10% of total revenues during the year ended December 
31, 1996.

INTERIM FINANCIAL INFORMATION

The interim financial statements included herein have been prepared, without 
audit, pursuant to the rules and regulations of the Securities and Exchange 
Commission.  Certain information and footnote disclosures normally included 
in financial statements prepared in accordance with generally accepted 
accounting principles have been condensed or omitted pursuant to such rules 
and regulations, although the management of the Company believes that the 
disclosures are adequate to make the information presented not misleading. 
Interim financial statements are by necessity somewhat tentative; judgments 
are used to estimate interim amounts for items that are normally determinable 
only on an annual basis.

The interim period information included herein reflects all adjustments which 
are, in the opinion of the management of the Company, necessary for a fair 
statement of the results of the respective interim periods.  Results of 
operations for interim periods are not necessarily indicative of results to 
be expected for an entire year.

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 at the date of the 
financial statements and the reported amounts of revenues and expenses during 
the reporting period.  Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash and short-term investments with 
original maturity dates of three months or less at the time of purchase.

PROPERTY AND EQUIPMENT

Property and equipment is stated at cost; depreciation is computed on a 
double declining basis over the estimated useful lives of the individual 
assets, which are five years for computers and equipment and seven years for 
furniture and fixtures.  When property and equipment is retired or otherwise 
disposed of, the cost and related accumulated depreciation are removed from 
the accounts and the resulting gain or loss is reflected in income.

SOFTWARE

The costs of internally developed software which meet the criteria in 
Statement of Financial Accounting Standards No. 86, "Accounting for the Costs 
of Computer Software to be Sold, Leased or Otherwise Marketed," (SFAS 86) are 
periodically evaluated for capitalization purposes. To date, the Company has 
not considered qualifying costs under the strict guidelines prescribed by 
SFAS 86 to be significant.  Accordingly, no such costs have been reflected on 
the accompanying balance sheet.

REVENUE RECOGNITION

License revenues with no future obligations on the part of the Company are 
recognized upon shipment to the customer.  Licenses which include significant 
amounts of tailoring and, occasionally, customization are recognized upon 
completion of contract obligations.  Revenues for consulting, custom 
programming and training, where separately contracted for, are recognized as 
the related services are performed.  Amounts received in advance for 
maintenance and support contracts are deferred and recognized ratably over 
the agreement period, generally 12 months.

                                      F-27

facility to be ready in November 1997.  The lease is a five-year lease for
20,000 square feet, with an option to extend the lease term for an additional

7.  INCOME TAXES:

TCV is a limited liability company (L.L.C.) and, accordingly, is not liable for
federal or state income taxes since the L.L.C.'s income or loss is reported on
the separate tax returns of the members.  For all periods presented, however,
there was no significant revenues, expenses or other transaction activity by
TCV.

RTI accounts for income taxes in accordance with Statement of Financial
Accounting Standards No. 109, "Accounting For Income Taxes" (SFAS 109).  This
pronouncement requires deferred tax assets and liabilities to be valued using
the enacted tax rates expected to be in effect when the temporary differences
are recovered or settled.

The reconciliation of the statutory federal income tax rate to the Company's
effective income tax rate (1995 represents predecessor and TCV combined),
excluding one-time nondeductible acquisition expenses of $2,520,000, is as
follows:

In accordance with SFAS 109, RTI has recorded the following deferred taxes as

RTI has no significant deferred tax liabilities as of December 31, 1996.  No
benefit for deferred tax assets has been reflected in the accompanying
financial statements as they do not satisfy the recognition criteria set forth
in SFAS 109.

The increase (decrease) in the valuation allowance is as follows:

                                          Year Ended December 31,
                                --------------------------------------

Increase (decrease) in:
  Valuation allowance             $38,000     $(107,000)      $(75,000)

RTI's net operating loss carryforwards expire through 2011.  The Tax Reform Act
of 1986 contains provisions which limit the net operating loss carryovers
available to be used in any given year in the event of certain circumstances
including significant changes in ownership interests.  As a result of prior
ownership changes, the Company is limited to using approximately $190,000 of
net operating loss carryovers in any one year.

8.  STOCK OPTIONS:

RTI has an incentive stock option plan.  Under the plan, options vest ratably
over four years and expire 10 years from the date of grant or 30 days after
employment termination. The exercise price for the incentive stock options
granted under the plan is set at the fair market value at the grant date.

In addition, RTI has granted 60,000 nonqualified stock options to a director.
These options vest over four years and expire ten years from date of grant.  As
of December 31, 1996, none of these options have vested.

During 1995, the Financial Accounting Standards Board issued Statement No. 123
(SFAS 123), "Accounting for Stock-Based Compensation," which establishes a fair
value-based method of accounting for stock-based compensation plans and
requires additional disclosures for those companies that elect not to adopt the
new method of accounting.





                                     F-30
<PAGE>

The Company has elected to account for its stock-based compensation plan under
APB 25.  However, the Company has computed, for pro forma disclosure purposes,
the value of all options granted during 1995 and 1996 using the Black-Scholes
option-pricing model as prescribed by SFAS 123.  The following assumptions were
used for grants in fiscal 1995 and 1996:

   Risk-free interest rate                                  5.26%
   Expected dividend yield                                     0%
   Expected life                                          7 years
   Expected volatility                                        40%

The total value of options granted during fiscal 1995 and 1996 will be
amortized on a pro forma basis over the vesting period of the options.  Options
generally vest equally over four years.  If the Company had accounted for these
plans in accordance with SFAS 123, the Company's net income (loss) would have
changed as reflected in the following pro forma amounts:

                                  December 31,      December 31,
                                1995 (combined)         1996
                                ---------------     ------------
                                  (Unaudited)
Net income (loss):
  As reported                     $(2,241,000)       $674,000
  Pro forma                        (2,242,000)        660,000

The Company has not and does not currently have any plans to issue equity
instruments other than options to purchase Common Stock of RTI.  A summary of
the status of the RTI's stock option plans and changes for the years ended
December 31, 1995 and 1996 are presented in the following table:

                         NOTES TO FINANCIAL STATEMENTS
                                       
                FOR THE YEARS ENDED DECEMBER 31, 1995 AND 1996

1.  NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

NATURE OF BUSINESS

Rosetta Technologies, Inc. (the Company) was established in 1986 in Beaverton,
Oregon, to develop, sell and service software used in the manufacturing and
engineering environment.  The Company's software acts as an interactive data
viewer that relays valuable information, such as describing how products are
engineered, manufactured, and supported throughout a product's life cycle.  The
Company's products are sold both domestically and internationally.  During the
years ended December 31, 1995 and 1996, 84% and 77% of revenues were from
domestic customers and 16% and 23% from international customers, respectively.
Also, during the year ended December 31, 1994 (unaudited), three of the
Company's customers accounted for 28%, 18% and 12% of total revenues.  During
the year ended December 31, 1995, one of the Company's customers accounted for
15% of total revenues.  There were no individual customers accounting for more
than 10% of total revenues during the year ended December 31, 1996.


INTERIM FINANCIAL INFORMATION

The interim financial statements included herein have been prepared, without
audit, pursuant to the rules and regulations of the Securities and Exchange
Commission.  Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to such rules and
regulations, although the management of the Company believes that the
disclosures are adequate to make the information presented not misleading.
Interim financial statements are by necessity somewhat tentative; judgments are
used to estimate interim amounts for items that are normally determinable only
on an annual basis.

The interim period information included herein reflects all adjustments which
are, in the opinion of the management of the Company, necessary for a fair
statement of the results of the respective interim periods.  Results of
operations for interim periods are not necessarily indicative of results to be
expected for an entire year.

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period.  Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash and short-term investments with original
maturity dates of three months or less at the time of purchase.

PROPERTY AND EQUIPMENT

Property and equipment is stated at cost; depreciation is computed on a double
declining basis over the estimated useful lives of the individual assets, which
are five years for computers and equipment and seven years for furniture and
fixtures.  When property and equipment is retired or otherwise disposed of, the
cost and related accumulated depreciation are removed from the accounts and the
resulting gain or loss is reflected in income.

                                       F - 38

SOFTWARE

The costs of internally developed software which meet the criteria in Statement
of Financial Accounting Standards No. 86, "Accounting for the Costs of Computer
Software to be Sold, Leased or Otherwise Marketed," (SFAS 86) are periodically
evaluated for capitalization purposes. To date, the Company has not considered
qualifying costs under the strict guidelines prescribed by SFAS 86 to be
significant.  Accordingly, no such costs have been reflected on the
accompanying balance sheet.

REVENUE RECOGNITION

License revenues with no future obligations on the part of the Company are
recognized upon shipment to the customer.  Licenses which include significant
amounts of tailoring and, occasionally, customization are recognized upon
completion of contract obligations.  Revenues for consulting, custom
programming and training, where separately contracted for, are recognized as
the related services are performed.  Amounts received in advance for
maintenance and support contracts are deferred and recognized ratably over the
agreement period, generally 12 months.

ADVERTISING COSTS

Advertising costs are expensed as incurred.  Advertising costs included in
sales and marketing expenses in the accompanying statements of operations were
$53,000, $69,000 and $137,000 for the years ended December 31, 1994
(unaudited), 1995 and 1996, respectively.

2.  PROPERTY AND EQUIPMENT:

3.  EMPLOYEE BENEFIT PLANS:

The Company has a tax deferred retirement plan (the Plan) under the provisions
of Section 401(k) of the Internal Revenue Code.  Employer contributions to the
Plan are made at the discretion of the Board of Directors.  Contributions for
the years ended December 31, 1994 (unaudited), 1995 and 1996 were $0, $0 and
$38,000, respectively.

4.  LINE OF CREDIT:

In 1996, the Company obtained a $500,000 operating line of credit with a bank
at an interest rate of prime plus .5%.  All advances are payable upon demand
and are collateralized by accounts receivable and equipment.  The agreement
contains covenants which require the Company to maintain certain financial
ratios.  The Company is in compliance with these covenants as of December 31,
1996.  There were no borrowings on the line at December 31, 1996.

5.  CONVERTIBLE NOTE PAYABLE - RELATED PARTY:

The Company has a promissory note with a corporation controlled by one of the
Company's shareholders.  This note is convertible into common stock at the
option of the holder at any time prior to full payment of the note by the
Company.  The conversion rate is $1.875 per share.  The note is due in full on
November 15, 1998 and bears interest at the rate of 10%.  Interest only
payments are due monthly.

6.  OPERATING LEASES:

The Company leases its facility and certain computer equipment under operating
leases, with terms of three years, payable in monthly installments.  Total
operating lease expense for the years ended December 31, 1994 (unaudited), 1995
and 1996 was $52,000, $103,000 and $117,000, respectively.

Subsequent to December 31, 1996, the Company signed a lease for a new office
facility to be ready in November 1997.  The lease is a five-year lease for
20,000 square feet, with an option to extend the lease term for an additional
two years.  Lease payments are payable in monthly installments and have been
included in the future minimum lease payment schedule.

Future minimum lease payments for the years ending December 31 are as follows:

                   1997                                 $  123,000

                                                        ==========

7.  INCOME TAXES:

The Company accounts for income taxes in accordance with Statement of Financial
Accounting Standards No. 109, "Accounting For Income Taxes" (SFAS 109).  This
pronouncement requires deferred tax assets and liabilities to be valued using
the enacted tax rates expected to be in effect when the temporary differences

The net operating loss carryforwards expire through 2011.  The Tax Reform Act
of 1986 contains provisions which limit the net operating loss carryovers
available to be used in any given year in the event of certain circumstances
including significant changes in ownership interests.  As a result of prior
ownership changes, the Company is limited to using approximately $190,000 of
net operating loss carryovers in any one year.

8.  STOCK OPTIONS:

The Company has an incentive stock option plan.  Under the plan, options vest
ratably over four years and expire 10 years from the date of grant or 30 days
after employment termination. The exercise price for the incentive stock
options granted under the plan is set at the fair market value at the grant
date.

In addition, the Company has granted 60,000 nonqualified stock options to a
director.  These options vest over four years and expire ten years from date of
grant.  As of December 31, 1996, none of these options have vested.

During 1995, the Financial Accounting Standards Board issued Statement No. 123
(SFAS 123), "Accounting for Stock-Based Compensation," which establishes a fair
value-based method of accounting for stock-based compensation plans and
requires additional disclosures for those companies that elect not to adopt the
new method of accounting.

The Company has elected to account for its stock-based compensation plan under
APB 25.  However, the Company has computed, for pro forma disclosure purposes,
the value of all options granted during 1995 and 1996 using the Black-Scholes
option-pricing model as prescribed by SFAS 123.  The following assumptions were
used for grants in fiscal 1995 and 1996:

             Risk-free interest rate                        5.26%
             Expected dividend yield                           0%
             Expected life                                7 years
             Expected volatility                              40%

The total value of options granted during fiscal 1995 and 1996 will be
amortized on a pro forma basis over the vesting period of the options.  Options
generally vest equally over four years.  If the Company had accounted for these
plans in accordance with SFAS 123, the Company's net income would have
decreased as reflected in the following pro forma amounts:

                                                  --------     -----------
Net income:

                  AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER
                                           
    AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER, dated as of October 30,
1997 (the "Agreement"), by and among ENGINEERING ANIMATION, INC., a Delaware
corporation ("EAI"), COHO, INC., an Iowa corporation and a wholly-owned
subsidiary of EAI ("Sub"), and CIMTECH, INC., an Iowa corporation ("Cimtech").

    WHEREAS, the Boards of Directors of EAI and Cimtech have determined that it
is in the best interests of their respective companies and stockholders to
consummate the business combination provided for in this Agreement in which Sub,
subject to the terms and conditions set forth herein, shall merge with and into
Cimtech (the "Merger") and as a result Cimtech shall become a wholly-owned
subsidiary of EAI;

    WHEREAS, the parties desire to make certain representations, warranties and
agreements in connection with the Merger and to establish certain conditions to
the Merger.

    WHEREAS, the parties entered into an Agreement and Plan of Merger dated
October 29, 1997, which they now wish to amend and restate to provide that the
stock of EAI to be received by the shareholders of Cimtech in connection with
the Merger will be issued pursuant to a private placement and to provide
registration rights in connection therewith.

    NOW, THEREFORE, in consideration of the mutual covenants, representations,
warranties and agreements contained herein, the parties agree as follows:

                                  ARTICLE I.

                                  THE MERGER

    1.1. THE MERGER.  Subject to the terms and conditions of this Agreement, 
in accordance with the Iowa Business Corporation Act (the "IBCA"), at the 
Effective Time (as hereinafter defined), Sub shall merge with and into 
Cimtech.  Cimtech shall be the surviving corporation in the Merger 
(hereinafter sometimes referred to as the "Surviving Corporation"), and shall 
continue its corporate existence under the laws of the State of Iowa as a 
wholly-owned subsidiary of EAI.  Upon consummation of the Merger, the 
separate corporate existence of Sub 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 10:00 a.m., at the 
offices of Gardner, Carton & Douglas, 321 North Clark Street, Chicago, 
Illinois, not later than five 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.  The Merger shall become effective as set forth in 
articles of merger substantially in the form attached as EXHIBIT A (the 
"Articles of Merger"), which shall be filed with the Secretary of State of 
the State of Iowa (the "Iowa Secretary") on the Closing Date.  

<PAGE>

The term "Effective Time" shall be the date and time when the Merger becomes 
effective, as set forth in the Articles of Merger.

    1.4. EFFECTS OF THE MERGER.  At and after the Effective Time, the Merger
shall have the effects set forth in the IBCA.

    1.5. CERTIFICATE OF INCORPORATION AND BY-LAWS.  Subject to the terms and
conditions of this Agreement, at the Effective Time, the Articles of
Incorporation and By-Laws of Cimtech shall be the Articles of Incorporation and
By-Laws of the Surviving Corporation until thereafter amended in accordance with
applicable law.

    1.6. DIRECTORS AND OFFICERS.  The directors and officers of Sub immediately
prior to the Effective Time shall continue as the directors and officers of the
Surviving Corporation, unless and until thereafter changed in accordance with
the IBCA and the Surviving Corporation's Articles of Incorporation and By-Laws.

    1.7. SUB COMMON STOCK.  At the Effective Time, each share of Sub Common
Stock issued and outstanding immediately prior thereto shall be converted into
one share of common stock, $1.00 par value, of the Surviving Corporation.

    1.8. TAX AND ACCOUNTING CONSEQUENCES.  EAI and Cimtech 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.  EAI and Cimtech also intend that the Merger be 
accounted for as a pooling of interests pursuant to Opinion No. 16 of the 
Accounting Principles Board.

                                 ARTICLE II.

                     CONVERSION AND EXCHANGE OF SHARES

    2.1. CONVERSION OF CIMTECH COMMON STOCK. At the Effective Time, by virtue 
of the Merger and without any action on the part of EAI, Sub, Cimtech or any 
shareholder of Cimtech:

    (a)  Each share of the common stock, par value $1.00 per share, of 
Cimtech (the "Cimtech Common Stock") issued and outstanding immediately prior 
to the Effective Time shall be converted into the right to receive shares of 
the common stock, par value $.01 per share, of EAI (the "EAI Common Stock") 
at an exchange ratio (the "Exchange Ratio") determined as follows:  each 
share of Cimtech Common Stock shall be exchanged for that number of shares of 
EAI Common Stock equal to the quotient of (x) the number obtained by dividing 
$6,000,000 by the total of the number of shares of Cimtech Common Stock 
outstanding immediately prior to the Effective Time plus the number of shares 
of Cimtech Common Stock issuable upon the exercise of all outstanding options 
to purchase Cimtech Common Stock (the "Cimtech Options"), divided by (y) the 
average of the high and low per share sale price of the EAI Common Stock, as 
reported on the Nasdaq Stock Market National Market (the "NNM") for each of 
the ten trading days immediately preceding and including the second trading 
day prior to the Closing, as reported in the NNM listings published in THE 
WALL STREET JOURNAL (the "EAI Stock Value"); 

                                 2
<PAGE>

provided, however, in determining the Exchange Ratio and for all other 
purposes under this Agreement, the EAI Stock Value shall in no event be less 
than $32.00 or more than $48.00.  No fractional  shares of EAI Common Stock 
shall be issued, and in lieu thereof, EAI shall pay to each former 
shareholder of Cimtech 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 
2.1.

    (b)  All of the shares of Cimtech Common 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 
certificate previously representing any such shares of Cimtech Common Stock 
(a "Common 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 Cimtech 
Common Stock represented by such Common Certificate have been converted.  If, 
prior to the Effective Time, the outstanding shares of EAI Common Stock or 
Cimtech Common 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 the 
Exchange Ratio.

    (c)  At the Effective Time, all shares of Cimtech Common Stock that are 
owned by Cimtech as treasury stock and all shares of Cimtech Common Stock 
that are owned, directly or indirectly, by Cimtech, 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 Cimtech shall become treasury 
stock of EAI.

    (d)  After the Effective Time, there shall be no transfers on Cimtech's 
stock transfer books of shares of Cimtech Common Stock.

    2.2. EXCHANGE OF SHARES.  (a) At the Closing, each shareholder of Cimtech 
shall have the right to deliver to EAI Common Certificates representing all 
of the issued and outstanding shares of Cimtech Common 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 Common Certificate 
for exchange and cancellation to EAI, and in accordance with and subject to 
the other provisions of this Agreement, the holder of such Common Certificate 
shall receive in exchange therefor (i) a certificate representing that number 
of whole shares of EAI Common Stock to which such holder of Cimtech Common 
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 Common 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 Common Certificates.

                                      3
<PAGE>

    (b)  If any certificate representing shares of EAI Common Stock is to be 
issued in a name other than that in which the Common Certificate surrendered 
in exchange therefor is registered, it shall be a condition of the issuance 
thereof that the Common 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 Common 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 Common Certificate.  Thereafter, EAI shall issue in 
exchange for such lost, stolen or destroyed Common Certificate the shares of 
EAI Common Stock and any cash in lieu of a fractional share deliverable in 
respect thereof pursuant to this Agreement.

    2.3. OPTIONS TO ACQUIRE CIMTECH COMMON STOCK.

    (a)  At the Effective Time, each outstanding Cimtech Option shall be 
assumed by EAI.  each such Cimtech Option shall thereafter be deemed to 
constitute an option to acquire, on the same terms and conditions as were 
applicable under such cimtech option, (i) the same number of shares of EAI 
Common Stock as such Cimtech Option would have been exchangeable for had such 
Cimtech 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 Cimtech Common 
Stock otherwise purchasable pursuant to such Cimtech Option divided by (B) 
the number of whole 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 
Cimtech Option shall not include any fractional share and, upon exercise of 
such Cimtech 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 and Sub's obligations to consummate the Merger, each 
holder of a Cimtech Option 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 Cimtech Options appropriate notices setting forth such 
holders' rights and the agreements evidencing the grants of such Cimtech 
Options shall be deemed to be appropriately amended so that such Cimtech 
Options shall represent rights to acquire EAI Common Stock on terms and 
conditions as contained in the outstanding Cimtech Options (subject to the 
adjustments required by this Section 2.3 after giving effect to the 
assumption by EAI as set forth above).  

    (c)  The amended Cimtech Options shall be issued under a non-qualified 
stock option plan to be implemented by EAI prior to the Effective Time.  
Prior to the Effective Time, EAI shall file a registration statement on Form 
S-8 (or any successor or other appropriate form) with respect to the shares 
of EAI Common Stock subject to such plan and shall use its reasonable 

                                    4

<PAGE>

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.

    (d)  At the Effective Time, all outstanding warrants, options, phantom 
stock, convertible securities or any other rights to acquire shares of 
Cimtech Common Stock other than the Cimtech Options and Warrant issued to the 
Iowa Product Development Corporation (the "IPDC Warrant"), if any such rights 
exist, shall be canceled and extinguished without any conversion thereof or 
payment with respect thereto. 

                                ARTICLE III.

                  REPRESENTATIONS AND WARRANTIES OF CIMTECH

    3.10.     TAXES AND TAX RETURNS.  

    (a)  (i)  Cimtech (which term for purposes of this Section 3.10 shall
    include former subsidiaries of Cimtech 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 Cimtech 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 the date hereof; and there are no outstanding summons, subpoenas
    or written requests for information with respect to any such Returns or the
    Taxes reflected thereon.  To Cimtech'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
    Cimtech may be subject and Cimtech is not under audit by any Governmental
    Authority for any Tax.  There are no Tax liens on any assets of Cimtech
    other than liens for Taxes not yet due or payable;

         (ii) Cimtech has paid, on the basis of Cimtech'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 Cimtech's books as an accrued Tax liability,
    either current or deferred. The amount of such Tax liabilities as of
    September 30, 1997 shall be set forth in Section 3.10 of the Disclosure
    Schedule.  All Taxes required to be withheld, collected or deposited by
    Cimtech 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, Cimtech 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 Cimtech; and no other
    entity that was included in the filing of a Return with Cimtech on a
    consolidated, combined, or unitary basis has left Cimtech's consolidated,
    combined or unitary group in a taxable year for which the statute of
    limitations on assessment remains open.  Cimtech 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 Cimtech; and

                                      8
<PAGE>


         (v)  There is no significant difference on the books of Cimtech
    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.

    (b)  Cimtech: 

         (i)  Does not have any property that is or will be required to be
    treated as being owned by another person under the provisions of
    Section 168(f)(8) of the Code (as in effect prior to amendment by the Tax

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 Cimtech shareholder meeting shall not have
occurred in accordance with the requirements of the IBCA 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 March 31, 1998; or

    (d)  by the Board of Directors of Cimtech (after consulting with its 
legal counsel), if such action is required for the Board of Directors to 
comply with its fiduciary duties to Cimtech and its shareholders as 
contemplated in Section 6.8 hereof; PROVIDED, HOWEVER, if such action is 
taken by Cimtech, then (i) within 2 days of such termination Cimtech shall 
reimburse EAI for its out-of-pocket expenses incurred in connection with the 
transactions contemplated by this Agreement; and (ii) if Cimtech shall 
consummate any transaction pursuant to a Takeover Proposal (x) within 12 
months following the date of this Agreement, or (y) pursuant to a definitive 
agreement executed by Cimtech during such 12-month period, Cimtech shall also 
promptly pay to EAI $500,000 upon the occurrence of such transaction; 

PROVIDED, HOWEVER, if the Cimtech shareholder meeting shall have occurred and 
the Cimtech 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 Cimtech shareholder meeting without further action of any of 
the parties hereto and within 2 days of such termination Cimtech 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 Cimtech or EAI as provided in Section 8.1, this Agreement 
shall forthwith become void and have no effect, and none of Cimtech, 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 Cimtech nor EAI shall be relieved or released 

                                     28
<PAGE>

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 Cimtech, 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 Cimtech
Common Stock hereunder other than as contemplated by this Agreement.  Any
agreement on the part of a party hereto to any such 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

    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, Cimtech 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,
Exhibits, documents and instruments referred to herein) 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 Delaware, without regard to any
applicable conflicts of law which would result in the application of any other
law.

                                     30
<PAGE>


    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 Cimtech 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 Cimtech, such term shall 
include the "knowledge" or "awareness" of the directors, officers and other 
persons exercising supervisory authority over Cimtech and the shareholders of 
Cimtech who are active in the business of Cimtech.

    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.     POOLING OF INTERESTS ACCOUNTING; TAX FREE REORGANIZATION.  In 
the event that either EAI or Cimtech becomes aware of any provisions of this 
Agreement which would prevent the Merger from being accounted for as a 
pooling of interests or qualifying as a reorganization within the meaning of 
Section 368 of the Code, such parties shall negotiate in good faith with a 

                                      31

<PAGE>


view toward amending this Agreement in a manner which would permit the Merger 
to be accounted for as a pooling of interests or qualified as such a 
reorganization, as applicable.

     AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER, dated as of November 
14, 1997 (the "Agreement"), by and among ENGINEERING ANIMATION, INC., a 
Delaware corporation ("EAI"), TRANSITORY BEAVER, INC., a Delaware corporation 
and an indirect wholly-owned subsidiary of EAI ("Sub"), and ROSETTA 
TECHNOLOGIES, INC., an Oregon corporation ("RTI").

     WHEREAS, EAI, Shell Beaver L.L.C., a Delaware limited liability company, 
the sole member of which is EAI ("Beaver"), and Technology Company Ventures, 
L.L.C., an Oregon limited liability company and majority shareholder of RTI 
("Ventures"), have entered into that certain Agreement and Plan of Merger, 
dated October 29, 1997, pursuant to which Ventures will merge with and into 
Beaver (the "Ventures Merger") and the membership interests in Ventures shall 
be converted solely into voting stock of EAI;

     WHEREAS, EAI desires to acquire all outstanding shares of stock of RTI 
not held by Ventures solely in exchange for voting stock of EAI;

     WHEREAS, the Boards of Directors of EAI, Sub and RTI have determined 
that it is in the best interests of their respective companies and 
stockholders to consummate the business combination provided for in this 
Agreement in which, subject to the terms and conditions set forth herein, Sub 
shall merge with and into RTI (the "Merger") and as a result RTI shall become 
a wholly-owned subsidiary of Beaver;

     WHEREAS, for federal income tax purposes, it is intended that the Merger 
shall qualify as part of a reorganization within the meaning of Section 
368(a) of the Internal Revenue Code of 1986, as amended (the "Code");

     WHEREAS, the parties desire to make certain representations, warranties 
and agreements in connection with the Merger and to establish certain 
conditions to the Merger;

     WHEREAS, the parties entered into an Agreement and Plan of Merger dated

representations, warranties and agreements contained herein, the parties 
agree as follows:

     1.5. ARTICLES OF INCORPORATION AND BY-LAWS. Subject to the terms and

                                  ARTICLE II.

                        CONVERSION AND EXCHANGE OF SHARES

     2.1. CONVERSION OF RTI COMMON STOCK. At the Effective Time of the 
Merger, by virtue of the Merger and without any action on the part of EAI, 
Sub, RTI or any shareholder of RTI:

     (a)  Each share of common stock, par value $.001 per share, of RTI (the
"RTI Common Stock") issued and outstanding immediately prior to the Effective
Time of the Merger, other than shares which remain outstanding pursuant to
Section 2.1(c), shall be converted into the right to receive shares of the
common stock, par value $.01 per share, of EAI (the "EAI Common Stock") at an
exchange ratio (the "Exchange Ratio") determined as follows:  each share of RTI
Common Stock shall be exchanged for that number of shares of EAI Common Stock
equal to the quotient obtained by dividing (i) $25,550,000 divided by the
average of the high and low per

                                       2
<PAGE>

share sale price of the EAI Common Stock, as reported on the Nasdaq Stock 
Market National Market ("NNM") for each of the date hereof and the two 
immediately preceding trading days, as reported in the NNM listings published 
in THE WALL STREET JOURNAL (the "EAI Stock Value"), BY (ii) the sum of the 
total number of shares of RTI Common Stock outstanding immediately prior to 
the Effective Time plus the number of shares of RTI Common Stock issuable 
upon the exercise of all outstanding options to purchase RTI Common Stock 
(the "RTI Options") outstanding immediately prior to the Effective Time.  No 
fractional  shares of EAI Common Stock shall be issued, and in lieu thereof, 
EAI shall pay to each former shareholder of RTI 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 2.1.

     (b)  All of the shares of RTI Common 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 of the 
Merger.  Each certificate previously representing any such shares of RTI 
Common Stock (a "Common 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 RTI Common Stock represented by such Common Certificate have been 
converted.  If, prior to the Effective Time, the outstanding shares of EAI 
Common Stock or RTI Common 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 the Exchange Ratio.

     (c)  At the Effective Time of the Merger, all shares of RTI Common Stock 
that are owned by RTI as treasury stock shall be canceled and all shares of 
RTI Common Stock that are owned, directly or indirectly, by Beaver or any 
other entity wholly-owned by EAI shall remain outstanding, and no stock of 
EAI or other consideration shall be delivered in exchange therefor.  At the 
Effective Time of the Merger, all shares of EAI Common Stock that are owned 
by RTI, if any, shall become treasury stock of EAI.

     (d)  After the Effective Time of the Merger, there shall be no transfers 
on RTI's stock transfer books of shares of RTI Common Stock.

     2.2. EXCHANGE OF RTI SHARES.

     (a)  At the Effective Time of the Merger, each shareholder of RTI shall 
have the right to deliver to EAI Common Certificates representing all of the 
issued and outstanding shares of RTI Common 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 Common Certificate 
for exchange and cancellation to EAI, and in accordance with and subject to 
the other provisions of this Agreement, the holder of such Common Certificate 
shall receive in exchange therefor (i) a certificate representing that

                                       3
<PAGE>

number of whole shares of EAI Common Stock to which such holder of RTI Common 
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 Common 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 Common Certificates.

     (b)  If any certificate representing shares of EAI Common Stock is to be
issued in a name other than that in which the Common Certificate surrendered in
exchange therefor is registered, it shall be a condition of the issuance thereof
that such Common 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 Common 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 Common Certificate.  Thereafter, EAI shall issue in exchange for
such lost, stolen or destroyed Common Certificate the shares of EAI Common Stock
and any cash in lieu of a fractional share deliverable in respect thereof
pursuant to this Agreement.

     2.3. OPTIONS TO ACQUIRE RTI COMMON STOCK.

     (a)  At the Effective Time of the Merger, each outstanding RTI Option, 
whether vested or unvested, shall be assumed by EAI.  Each such RTI Option 
shall thereafter be deemed to constitute an option to acquire, on the same 
terms and conditions as were applicable under such RTI Option and the plan 
related thereto, (i) the same number of shares of EAI Common Stock as such 
RTI Option would have been exchangeable for had such RTI 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 RTI Common Stock otherwise 
purchasable pursuant to such RTI Option divided by (B) the number of whole 
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 RTI Option shall not 
include any fractional share and, upon exercise of such RTI 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.  

     (b)  As soon as practicable after the Effective Time of the Merger, EAI 
shall deliver to the holders of RTI Options appropriate notices setting forth 
such holders' rights and the agreements evidencing the grants of such RTI 
Options shall be deemed to be appropriately amended so that such RTI Options 
shall represent rights to acquire EAI Common Stock on terms and conditions as 
contained in the outstanding RTI Options (subject to the adjustments required 
by this Section 2.3 after giving effect to the assumption by EAI as set forth 
above).

                                       4
<PAGE>

     (c)  The amended RTI Options shall be issued under EAI's employee stock
option plan as incentive stock options.  EAI has filed a registration statement
on Form S-8 with respect to the shares of EAI Common Stock subject to such plan
and shall use all 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.  The shares of EAI Common Stock subject to such
plan have been approved for listing on the NNM.

     (d)  At the Effective Time of the Merger, all outstanding warrants,
options, phantom stock, convertible securities or any other rights to acquire
shares of RTI Common Stock other than the RTI Options, if any such rights exist,
shall be canceled and extinguished without any conversion thereof or payment
with respect thereto.

                                 ARTICLE III.

                    REPRESENTATIONS AND WARRANTIES OF RTI

     Except as disclosed by RTI in the disclosure schedule delivered pursuant 
to this Agreement (the "Disclosure Schedule"), RTI represents and warrants to 
EAI as follows:

     3.1. CORPORATE ORGANIZATION. (a) RTI and the entities listed in Section 
3.1(b) of the Disclosure Schedule which are designated as subsidiaries in 
such Section ("Subsidiaries") are each a corporation duly organized, validly 
existing and in good standing under the laws of its jurisdiction of 
incorporation, which is set forth in Section 3.1(b) of the Disclosure 
Schedule. RTI and each Subsidiary have the corporate power and authority to 
own or lease all of their respective properties and assets and to carry on 
their respective business as it is now being conducted, and are duly licensed 
or qualified to do business and are in good standing in each jurisdiction in 
which the nature of the business conducted by them or the character or 
location of the properties and assets owned or leased by them makes such 
licensing or qualification necessary, except where the failure to be so 
licensed or qualified would not have a material adverse effect on the 
business, properties, profits, operations or financial condition (a "Material 
Adverse Effect") of RTI.  Correct and complete copies of the Articles of 
Incorporation and By-Laws of RTI and the charter documents and by-laws of 
each Subsidiary, as in effect on the date of this Agreement, have been made 
available to EAI by RTI.  For the purposes of this Article III and Article 
VI, each reference to RTI shall also include each Subsidiary, unless the 
context requires otherwise.

     (b)  Except as set forth in Section 3.1(b) of the Disclosure Schedule, 
RTI 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 
partnership, limited liability company, joint venture or other non-corporate 
business.

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

     3.2. CAPITALIZATION. The authorized capital stock of RTI consists of
25,000,000 shares of RTI Common Stock, of which 9,874,975 shares are issued and
outstanding.  The name and address of record of each record holder of RTI Common
Stock and the number of shares owned

                                       5
<PAGE>

by each, and the name and address of record of each holder of an RTI Option 
and the number of shares of RTI Common Stock which such holder may purchase, 
are set forth in Section 3.2 of the Disclosure Schedule.  No shares of RTI 
Common Stock are held in RTI's treasury and no shares of RTI Common Stock are 
reserved for issuance other than those shares reserved for issuance under the 
RTI Options.  All of the issued and outstanding shares of RTI Common Stock 
have been duly authorized and validly issued and are fully paid, 
nonassessable and free of preemptive rights.  Other than the RTI Options 
listed in Section 3.2 of the Disclosure Schedule, RTI 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.  

     3.3. AUTHORITY; NO VIOLATION. (a) RTI has the corporate power and 
authority to execute and deliver this Agreement and to consummate the 
transactions contemplated hereby. The execution and delivery of this 
Agreement and the consummation of the transactions contemplated hereby have 
been duly and validly approved by the Board of Directors of RTI. Except for 
the adoption of this Agreement by the requisite vote of holders of the issued 
and outstanding shares of RTI Common Stock, no other corporate proceedings on 
the part of RTI are necessary to approve this Agreement or to consummate the 
transactions contemplated hereby. This Agreement has been duly and validly 
executed and delivered by RTI and, assuming due authorization and execution 
by EAI and Sub, constitutes a valid and binding obligation of RTI, 
enforceable against RTI in accordance with its terms.

     (b)  The execution and delivery of this Agreement by RTI, the 
consummation by RTI of the transactions contemplated hereby, and the 
compliance by RTI with the terms or provisions hereof, shall not (i) violate 
any provision of the Articles of Incorporation or By-Laws of RTI, (ii) 
violate any law, statute, code, ordinance, rule, regulation, judgment, order, 
writ, decree or injunction applicable to RTI or any of its properties or 
assets, or (iii) violate, conflict with, breach any provision of or result in 
the loss of any benefit or the increase in the amount of any liability or 
obligation under, constitute a default (or an event which, with notice or 
lapse of time, or both, would constitute a default) under, result in the 
termination 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 
RTI under any note, bond, mortgage, indenture, deed of trust, license, lease, 
contract, agreement or other instrument or obligation to which RTI is a 
party, or by which it or any of its properties or assets may be bound or 
affected, except where such violation, conflict, breach, loss, increase,

on RTI.

<PAGE>

governmental authority or instrumentality, whether Federal, state, local or 
foreign (each a "Governmental Authority"), or with any third party are

Agreement and the consummation by RTI of the Merger and the other 
transactions contemplated by this Agreement.

     3.5. REPORTS. RTI has timely filed all reports, registrations and
statements required to be filed since January 1, 1995 with any Governmental
Authority, and has paid all fees and assessments due and payable in connection
therewith, except where failure to so file or pay, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
RTI.  No Governmental Authority has initiated any proceeding or, to the
knowledge of RTI, investigation into the business or operations of RTI.

     3.6. COMPLIANCE WITH APPLICABLE LAW. RTI holds all licenses, 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 RTI, except where failure to so hold or
such default, individually or in the aggregate, would not reasonably be expected
to have a Material Adverse Effect on RTI.

and complete copies of the following (collectively, the "RTI Financial
Statements"):  (a) the balance sheets of RTI as of June 30, 1997 and 1996, and
the related statements of income and retained earnings and cash flows for the
fiscal years ended June 30, 1997 and 1996, in each case accompanied by the audit
report of Arthur Andersen LLP, independent public accountants with respect to
RTI, and (b) the unaudited balance sheets of RTI as of September 30, 1997 and
the related unaudited statements of income for the period then ended (the
"Interim Financial Statements"). The RTI Financial Statements fairly present

adjustments customary in nature and amount), the financial position of RTI as of
the dates thereof, and the results of operations and cash flows of RTI for the
respective fiscal periods or as of the respective dates thereof.  Each of the
RTI Financial Statements, including the notes thereto, has been, or will be,
prepared in accordance with generally accepted accounting principles ("GAAP")
consistently applied during the periods involved.  The books and records of RTI
have been, and are being, maintained in accordance with all applicable legal and
accounting requirements.

     3.8. ABSENCE OF CERTAIN CHANGES OR EVENTS. (a) Since June 30, 1997, 
(i) RTI 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, would reasonably be expected to have a Material Adverse 
Effect on RTI, and (iii) RTI 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 
June 30, 1997, RTI has not (i) increased the salaries, wages, or other 
compensation, or pensions, fringe benefits or other perquisites 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

which would, either individually or in the aggregate, result in a Material 
Adverse Effect on RTI.

     3.9. LEGAL PROCEEDINGS AND RESTRICTIONS (a) There are no actions, suits,
proceedings, claims or investigations pending, or to the knowledge of RTI,
threatened against or directly and materially affecting RTI at law or in equity
or before any Governmental Authority.

     (b)  There is no judgment, order, writ, decree, injunction or regulatory
restriction imposed upon RTI or its assets which has had, or would reasonably be
expected to have, a Material Adverse Effect on RTI.

     3.10.     TAXES AND TAX RETURNS.

     (a)  (i)  RTI (which term for purposes of this Section 3.10 shall include
     former subsidiaries of RTI 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 RTI 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 the date hereof; and
     there are no outstanding summons, subpoenas or written requests for
     information with respect to any such Returns or the Taxes reflected
     thereon.  To RTI'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 RTI may be subject and RTI is
     not under audit by any Governmental Authority for any Tax.  There are no
     Tax liens on any assets of RTI other than liens for Taxes not yet due or
     payable;

          (ii) RTI has paid, on the basis of RTI'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 RTI's books as an accrued Tax liability, either
     current or deferred. The amount of such Tax liabilities as of September 30,
     1997 shall be set forth in Section 3.10 of the Disclosure Schedule.  All
     Taxes required to be withheld, collected or deposited by RTI 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 or collection remains open, RTI 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 RTI; and no
     other entity that was included in the filing of a Return with RTI on a
     consolidated,

<PAGE>

     combined, or unitary basis has left RTI's consolidated, combined or 
     unitary group in a taxable year for which the statute of limitations
     on assessment remains open.  RTI 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 RTI; and

          (v)  There is no significant difference on the books of RTI 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.

     (b)  RTI: 

           (i) Does not have any property that is or will be required to be
     treated as being owned by another person under the provisions of
     Section 168(f)(8) of the Code (as in effect prior to amendment by the Tax

          (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;

     required certificates to avoid any such withholding.

     (c)  For purposes of this Agreement:

changes the form of the consideration to be delivered to such holders of RTI
Common Stock hereunder other than as contemplated by this Agreement.  Any
agreement on the part of a party hereto to any such 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.

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

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,
Exhibits, documents and instruments referred to herein) 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 Delaware, 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 RTI or EAI, shall nor shall they 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 directors, managers, officers, shareholders or members who are active
in the business of the entity and other persons exercising supervisory
authority.

     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.

                                    ARTICLE II.
                     CONVERSION AND EXCHANGE OF MEMBER INTERESTS

     2.1. CONVERSION OF VENTURES MEMBERSHIP INTERESTS. At the Effective Time of
the Merger, by virtue of the Merger and without any action on the part of EAI,
Sub, Ventures or any member of Ventures:

                                     2

<PAGE>

     (a)  The membership interests in Ventures (the "Ventures Membership
Interests") shall be converted into the right to receive an aggregate number of
whole shares of the common stock, par value $.01 per share, of EAI (the "EAI
Common Stock") (the "Exchange Consideration") determined as follows:  the
membership interests shall be exchanged for that number of shares of EAI Common
Stock equal to the product obtained by multiplying (i) $25,550,000 divided by
the average of the high and low per share sale price of the EAI Common Stock, as
reported on the Nasdaq Stock Market National Market ("NNM") for each of the date
hereof and the two immediately preceding trading days, as reported in the NNM
listings published in THE WALL STREET JOURNAL (the "EAI Stock Value"), BY
(ii) 6,753,166 (or such other number of shares of common stock, par value $.001
per share, of RTI (the "RTI Common Stock") owned by Ventures immediately prior
to the Effective Time of the Merger) divided by the sum of the total number of
shares of RTI Common Stock outstanding immediately prior to the Effective Time
plus the number of shares of RTI Common Stock issuable upon the exercise of all
outstanding options to purchase RTI Common Stock (the "RTI Options") outstanding
immediately prior to the Effective Time.  EAI will allocate the Exchange
Consideration among the members of Ventures in accordance with the liquidation
provisions of the Ventures' Operating Agreement as instructed by Ventures.  No
fractional shares of EAI Common Stock shall be issued, and in lieu thereof, each
holder of a Ventures membership interest who otherwise would be entitled to
receive a fractional share of EAI Common Stock will instead receive one
additional whole share of EAI Common Stock.

     (b)  The Ventures Membership Interests 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 of the Merger.  If, prior
to the Effective Time, the outstanding shares of EAI Common Stock or RTI Common
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 the Exchange
Consideration.

     2.2. EXCHANGE OF VENTURES MEMBERSHIP INTERESTS.  (a) At the Effective Time
of the Merger, in accordance with and subject to other provisions of this
Agreement, each member of Ventures shall receive, automatically and without any
further action on such member's part, in exchange for such member's Ventures
Membership Interest a certificate representing that number of whole shares of
EAI Common Stock to which such member shall have become entitled.  Upon such
exchange, the Ventures Membership Interest shall forthwith be canceled.

     (b)  If any certificate representing shares of EAI Common Stock is to be
issued in a name other than that of the Ventures member, it shall be a condition
of the issuance thereof 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.

                                 ARTICLE III.
                  REPRESENTATIONS AND WARRANTIES REGARDING RTI

Except as disclosed by Ventures in the disclosure schedule delivered pursuant to
this Agreement (the "Disclosure Schedule"), Ventures represents and warrants to
EAI as follows:

     3.1. CORPORATE ORGANIZATION.  (a) RTI and the entities listed in
Section 3.1(b) of the Disclosure Schedule which are designated as subsidiaries
in such Section ("Subsidiaries") are each a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation, which is set forth in Section 3.1(b) of the Disclosure Schedule. 
RTI and each Subsidiary have the corporate power and authority to own or lease
all of their respective properties and assets and to carry on their respective
business as it is now being conducted, and are duly licensed or qualified to do
business and are in good standing in each jurisdiction in which the nature of
the business conducted by them or the character or location of the properties
and assets owned or leased by them makes such licensing or qualification
necessary, except where the failure to be so licensed or qualified would not
have a material adverse effect on the business, properties, profits, operations
or financial condition (a "Material Adverse Effect") of RTI.  Correct and
complete copies of the Articles of Incorporation and By-Laws of RTI and the
charter documents and by-laws of each Subsidiary, as in effect on the date of
this Agreement, have been made available to EAI by RTI.  For the purposes of
this Article III, each reference to RTI shall also include each Subsidiary,
unless the context requires otherwise.

     (b)  Except as set forth in Section 3.1(b) of the Disclosure Schedule, RTI
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 partnership, limited
liability company, joint venture or other non-corporate business.

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

     3.2. CAPITALIZATION.  The authorized capital stock of RTI consists of
25,000,000 shares of RTI Common Stock, of which 9,874,975 shares are issued and
outstanding.  The name and address of record of each record holder of RTI Common
Stock and the number of shares owned by each, and the name and address of record
of each holder of an RTI Option and the number of shares of RTI Common Stock
which such holder may purchase, are set forth in Section 3.2 of the Disclosure
Schedule.  No shares of RTI Common Stock are held in RTI's treasury and no
shares of RTI Common Stock are reserved for issuance other than those shares
reserved for issuance under the RTI Options.  All of the issued and outstanding
shares of RTI Common Stock have been duly authorized and validly issued and are
fully paid, nonassessable and free of preemptive rights.  Other than the RTI
Options listed in Section 3.2 of the Disclosure Schedule, RTI 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.  

     3.3. REPORTS.  RTI has timely filed all reports, registrations and
statements required to be filed since January 1, 1995 with any Governmental
Authority, and has paid all fees and 

                                       4

<PAGE>

assessments due and payable in connection therewith, except where failure to 
so file or pay, individually or in the aggregate, would not reasonably be 
expected to have a Material Adverse Effect on RTI.  No Governmental Authority 
has initiated any proceeding or, to the knowledge of Ventures, investigation 
into the business or operations of RTI.

     3.4. COMPLIANCE WITH APPLICABLE LAW.  RTI holds all licenses, 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 RTI, except where failure to so hold or
such default, individually or in the aggregate, would not reasonably be expected
to have a Material Adverse Effect on RTI.

     3.5. FINANCIAL STATEMENTS.  RTI has previously provided EAI with correct
and complete copies of the following (collectively, the "RTI Financial
Statements"):  (a) the balance sheets of RTI as of June 30, 1997 and 1996, and
the related statements of income and retained earnings and cash flows for the
fiscal years ended June 30, 1997 and 1996, in each case accompanied by the audit
report of Arthur Andersen LLP, independent public accountants with respect to
RTI, and (b) the unaudited balance sheets of RTI as of September 30, 1997 and
the related unaudited statements of income for the period then ended (the
"Interim Financial Statements").  The RTI Financial Statements fairly present
(subject, in the case of the unaudited statements, to recurring audit
adjustments customary in nature and amount), the financial position of RTI as of
the dates thereof, and the results of operations and cash flows of RTI for the
respective fiscal periods or as of the respective dates thereof.  Each of the
RTI Financial Statements, including the notes thereto, has been, or will be,
prepared in accordance with generally accepted accounting principles ("GAAP")
consistently applied during the periods involved.  The books and records of RTI
have been, and are being, maintained in accordance with all applicable legal and
accounting requirements.

     3.6.  ABSENCE OF CERTAIN CHANGES OR EVENTS. (a) Since June 30, 1997, (i) 
RTI 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, would reasonably be expected to have a Material Adverse 
Effect on RTI, and (iii) RTI has carried on its business in the ordinary and 
usual course. 

     (b)  Except as set out in Section 3.6 of the Disclosure Schedule, since
June 30, 1997, RTI has not (i) increased the salaries, wages, or other
compensation, or pensions, fringe benefits or other perquisites 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 RTI.

     3.7. LEGAL PROCEEDINGS AND RESTRICTIONS  (a) There are no actions, suits,
proceedings, claims or investigations pending, or to the knowledge of Ventures,
threatened against or directly and materially affecting RTI at law or in equity
or before any Governmental Authority.

                                       5
<PAGE>


     (b)  There is no judgment, order, writ, decree, injunction or regulatory
restriction imposed upon RTI or its assets which has had, or would reasonably be
expected to have, a Material Adverse Effect on RTI.

     3.8. TAXES AND TAX RETURNS.  

     (a)  (i)  RTI (which term for purposes of this Section 3.8 shall include
     former subsidiaries of RTI 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 RTI 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 the date hereof; and
     there are no outstanding summons, subpoenas or written requests for
     information with respect to any such Returns or the Taxes reflected
     thereon.  To Ventures' knowledge there is no basis for imposing any
     additional Taxes on RTI 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 RTI may be
     subject and RTI is not under audit by any Governmental Authority for any
     Tax.  There are no Tax liens on any assets of RTI other than liens for
     Taxes not yet due or payable;

          (ii) RTI has paid, on the basis of RTI'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 RTI's books as an accrued Tax liability, either
     current or deferred. The amount of such Tax liabilities as of September 30,
     1997 shall be set forth in Section 3.8 of the Disclosure Schedule.  All
     Taxes required to be withheld, collected or deposited by RTI 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 or collection remains open, RTI 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 RTI; and no
     other entity that was included in the filing of a Return with RTI on a
     consolidated, combined, or unitary basis has left RTI's consolidated,
     combined or unitary group in a taxable year for which the statute of
     limitations on assessment remains open.  RTI 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;

     respect to RTI; and

          (v)  There is no significant difference on the books of RTI between

expected to have a Material Adverse Effect on RTI), against RTI, relating to
alleged employment discrimination, unfair labor practices, equal pay
discrimination, affirmative action noncompliance, occupational safety and
health, breach of employment contract, employee benefit matters, wrongful

assessments and penalties made against RTI pursuant to any applicable workers'
compensation legislation in any jurisdiction in which RTI conducts business have
been paid by RTI, other than such levies, assessments and penalties which,
individually or in the aggregate, are not material to RTI.  RTI is not a party
to any contracts with any labor union or employee association nor has RTI made
commitments to or conducted negotiations with any labor union or employee
association with respect to any future contracts.  Ventures is not aware of any
current attempts to organize or establish any labor union or employee
association with respect to any employees of RTI, and there is no existing or
pending certification of any such union with regard to a bargaining unit.

and effect, (ii) the consummation of the Merger will not cause a breach or
termination of any RTI Contract nor effect a change in any of the terms of any

valid leasehold interest in, the properties and assets used by it, located on
its premises, shown on the 1997 Balance Sheet or acquired after the date
thereof, except for properties and assets disposed of in the ordinary course of
business, free and clear of all Liens.  RTI owns or leases pursuant to a RTI
Contract all buildings, machinery, equipment and other tangible assets material

with notice or lapse of time, or both, would constitute a breach or default that

     the Intellectual Property and will continue to maintain those rights prior
     to the Closing so as not to affect materially the validity or enforcement

     4.12.     TAXES AND RETURNS.

     (a)  (i)  Ventures (which term for purposes of this Section 4.12 shall
     include any former subsidiaries of Ventures for periods during which they

     relating to any such Return has been proposed in writing by any
     Governmental Authority, except proposed adjustments that have been resolved
     prior to the date hereof; and there are no outstanding summons, subpoenas

     Governmental Authority;

     filed its income tax returns as a partnership.  Ventures has not been at
     any time a member of any partnership, limited liability company or joint

     "excess parachute payments" within the meaning of Section 280G of the Code
     by reason of the Merger; 

          (iii)     Will not owe any federal, state or local taxes as a result
     of the merger into Sub; and

     transaction under Sections 3406 or 1445 of the Code or any other provision
     of the Code or state, local or foreign law and Ventures will provide any
     required certificates to avoid any such withholding.

the agreements or conditions contained herein; PROVIDED, HOWEVER, that after

waiver shall be valid only if set forth in a written instrument signed on

condition in this Agreement shall not operate as a waiver of, or estoppel

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, Ventures or any of their respective affiliates to take any action which
would violate any applicable law, rule or regulation.

     10.4.     COUNTERPARTS.  This Agreement may be executed in counterparts,
all of which shall be considered one and the same agreement.

     10.5.     ENTIRE AGREEMENT.  This Agreement (including the Disclosure

the entire agreement of the parties and supersedes all prior agreements and
understandings, both written and oral, between the parties with respect to the

     10.6.     GOVERNING LAW.  This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware, without regard to any
applicable conflicts of law which would result in the application of any other
law.

     10.7.     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.

     10.8.     PUBLICITY.  Except as otherwise required by applicable law or the
rules of the NNM, neither Ventures nor EAI shall, nor shall they 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.

     10.9.     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

or "awareness" of any entity means the actual knowledge or awareness of such
entity's directors, managers, officers, shareholders or members who are active
in the business of the entity and other persons exercising supervisory
authority.

     10.11.    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.

     10.12.    POOLING OF INTERESTS ACCOUNTING.  In the event that EAI or
Ventures becomes aware of any provisions of this Agreement which would prevent
the Merger from being accounted for as a pooling of interests, such parties
shall negotiate in good faith with a view toward amending this Agreement in a
manner which would permit the Merger to be accounted for as a pooling of
interests.

     This Registration Rights Agreement (the "AGREEMENT") is made and entered
into as of ____________ ___, 1997 by and among Engineering Animation, Inc., a
corporation organized under the laws of the State of Delaware (the "COMPANY"),
and the holders of the Company's Common Stock, par value $.01 per share ("COMMON
STOCK") listed on EXHIBIT A hereto, (individually, a "HOLDER," and collectively,
the "HOLDERS").

                                  WITNESSETH:

     WHEREAS, the Company has entered into an Amended and Restated Agreement and
Plan of Merger dated as of October 30, 1997, with COHO, Inc., an Iowa
corporation and a wholly-owned subsidiary of the Company ("Sub"), and Cimtech,
Inc., an Iowa corporation ("Cimtech"), providing for the merger of Sub into
Cimtech (the "Merger Agreement");

     WHEREAS, pursuant to the Merger Agreement, the Holders will receive shares
of Common Stock in exchange for their shares of stock of Cimtech (the "MERGER
COMMON STOCK"); 

     WHEREAS, as an inducement to enter into the Merger Agreement, the Company
has agreed to enter into this Agreement with the Holders; and

     WHEREAS, in connection with the acquisition by the Company of Rosetta

of one of Rosetta's shareholders (collectively, the "Rosetta Holders") and will
enter into a Registration Rights Agreement with the Rosetta Holders pursuant to
which the Rosetta Holders will receive demand and "piggy-back" registration
rights.

     NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth below, the parties hereto agree as follows:

     2.   SHELF REGISTRATION.

    (a)  Subject to the limitations set forth in Sections 4, 5 and 7 hereof, as

Company with the Commission of its annual report on Form 10-K for the year
ending December 31, 1997, and (ii) the date on which the Company has made

of 30 days of combined operations of the Company and Cimtech, the Company 
shall notify in writing the Holders that the Company shall use its reasonable 
best efforts to promptly effect qualification and registration of the 
Registrable Securities under the Securities Act on a Form S-3 Registration 
Statement (the "REGISTRATION") if Holders constituting at least 15% of the 
total Registrable Securities then outstanding (the "SELLING HOLDERS") shall 
elect in writing within 15 Business Days to include such shares in the 
Registration.  Such election shall specify the name and address (including 
telephone and facsimile numbers) of each Holder requesting inclusion and the 
number of shares for which each such Holder is requesting to be included in 
the Registration (the "REGISTRATION NOTICE").  If Holders of at least 15% of 
the total Registrable Securities do not elect to include such shares in the 
Registration, the Company shall not be obligated to effect the Registration.  

     (b)  If required hereunder, the Company shall use its reasonable best
efforts to proceed with and complete the filing of a Registration Statement in
respect of the Registrable Securities as expeditiously as possible and in doing
so shall carry out the following actions:

          (i)    prepare the Registration Statement;

          (ii)   file the Registration Statement with the Commission and use its
     reasonable best efforts to cause the Registration Statement to become
     effective as soon as practicable following the 15 Business Day period in
     which Holders may elect to include their Registrable Securities in the
     Registration, and to keep such Registration Statement continuously
     effective until the earlier of (A) midnight on the sixtieth (60th) day
     following the Effective Date of the Registration, or at such later time as
     may be established pursuant to Sections 4(d), 5(b) or 7(a) or (B) the date
     on which no Registrable Securities for which the Registration has been
     initiated remain unsold (each a "DISTRIBUTION PERIOD");

          (iii)  prepare and file as expeditiously as possible with the
     Commission such amendments and supplements to the Registration Statement,
     and the Prospectus, as may be necessary to keep the Registration Statement
     effective during a Distribution Period;

          (iv)   furnish to each Selling Holder such number of copies of the
     Registration Statement and the Prospectus (including each preliminary
     prospectus) and any amendments or supplements thereto as such Selling
     Holder may reasonably request in order to facilitate the public sale or
     other disposition of the Registrable Securities;

          (v)    use its reasonable best efforts to register or qualify the
     Registrable Securities under the state securities or "blue sky" laws of
     such jurisdictions as each Selling Holder shall reasonably request and to
     maintain such qualification throughout the Distribution Period, except that
     the Company shall not be required for the purpose of such qualification to
     qualify generally to transact business as a foreign corporation in any
     jurisdiction where it is not so qualified or, except as to matters relating
     to the offer and sale of the Registrable Securities, consent to general
     service of process in any such jurisdiction;

<PAGE>

          (vi)   immediately notify each Selling Holder who elected to include
     Registrable Securities in the Registration Statement (A) of the Effective
     Date and the date when any post-effective amendment to the Registration
     Statement becomes effective, (B) of any stop order or notification from the
     Commission or any other jurisdiction as to the suspension of the
     effectiveness of the Registration Statement, and (C) of the happening of
     any event of which the Company has knowledge that would result in the
     Prospectus contained in the Registration Statement, as then in effect,
     including an untrue statement of a material fact or omitting to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading in light of the circumstances then
     existing;

          (vii)  timely file with the Commission all documents required to be
     filed by the Company pursuant to subsections 13(a), 13(c), 15(d), and
     Section 14 of the Exchange Act, and otherwise maintain its qualification to
     file a Registration Statement; and

          (viii) if the holders of a majority of the Registrable Securities to
     be registered on the Registration Statement so request on their notices to
     the Company requesting inclusion in the Registration, the Company shall use
     its reasonable best efforts to secure an investment banking firm of the
     Company's choice to act as underwriter, subject to the approval of the
     holders of a majority of the Registrable Securities to be registered on the
     Registration Statement, which approval shall not be unreasonably withheld,
     to retain one or more underwriters (on either a "firm commitment" or "best
     efforts" basis); provided that, if the Company is unable to secure a
     commitment from such an underwriter within 30 days following receipt of the
     Registration Notice, the Selling Holders may select one or more nationally
     recognized underwriters (on either a "firm commitment" or "best efforts"
     basis), subject to the approval of the Company, which approval shall not be
     unreasonably withheld;

          (ix)   if the Selling Holders request an underwriter pursuant to
     paragraph above, the Company shall take all reasonable actions as are
     necessary or advisable to expedite and facilitate the disposition of the
     Registrable Securities in the manner contemplated by the Registration
     Statement, to the same extent as if the Registrable Securities then being
     offered were for the account of the Company, including, without limitation,
     (A) entering into such customary agreements (including underwriting
     agreements in customary form) as the underwriters may reasonably request,
     and  (B) using its best efforts to furnish: (1) an opinion of counsel
     representing the Company for the purposes of such registration, dated the
     date the Registrable Securities are delivered to the underwriters for sale
     and addressed to the underwriters and the Selling Holders, (x) stating that
     the Registration Statement has become effective under the Securities Act,
     and that to the best knowledge of such counsel, no stop order suspending
     its effectiveness has been issued and no proceeding for that purpose has
     been instituted or is pending or contemplated under the Securities Act, (y)
     stating that the Registration Statement and each amendment or supplement
     thereto, comply as to form in all material respects with the requirements
     of the Securities Act (except that such counsel need not express any
     opinion as to financial statements contained therein) and (z) to such other
     effects as reasonably may be requested

<PAGE>

     by counsel for the underwriters, (2) letters dated the date of execution 
     of the underwriting agreement and the date of delivery of the 
     Registrable Securities (if so requested by the underwriters) and 
     addressed to the underwriters and the Selling Holders, from the 
     independent public accountants retained by the Company stating that they 
     are independent public accountants within the meaning of the Securities 
     Act that, in the opinion of those accountants, the financial statements 
     of the Company included in the Registration Statement, and any amendment 
     or supplement thereto, comply as to form in all material respects with 
     the applicable accounting requirements of the Securities Act, and 
     covering such other financial matters (including information as to the 
     period ending no more than five (5) business days prior to the date of 
     the letter) with respect to the registration as the underwriters 
     reasonably may request, and (3) for inspection by any underwriter 
     participating in any distribution pursuant to the Registration 
     Statement, and any attorney, accountant or other agent retained by any 
     underwriter, all pertinent financial and other records, pertinent 
     corporate documents and properties of the Company, and causing the 
     Company' officers, directors and employees to supply all information 
     reasonably requested by any underwriter, attorney, and accountant or 
     agent in connection with the Registration Statement, on the condition 
     that each of the foregoing have entered into confidentiality agreements 
     with the Company in respect of the information contained in such records 
     or documents.

     (c)  The Company shall not be required to effect more than one (1)
registration pursuant to the provisions of this Section 2.  In addition, the
Company may effect qualification and registration of the Registrable Securities
pursuant to this Section 2 pursuant to an existing shelf registration statement
or pursuant to an underwritten offering in accordance with the provisions of
Section 5 hereof.

     (d)  With a view toward making available to Holders the benefits of Rule
144 promulgated under the Securities Act and any other rule or regulation of the
Commission that may at any time permit a Holder to sell Registrable Securities
without registration or pursuant to a registration statement on Form S-3, the
Company agrees to:

          (i)    make and keep public information available, as those terms are
     understood and defined in Rule 144 promulgated under the Securities Act, at
     all times;

          (ii)   take such reasonable action as is necessary to maintain the
     ability of the Holders to utilize Form S-3 for the sale of their
     Registrable Securities;

          (iii)  file with the Commission in a timely manner all reports and
     other documents required of the Company under the Securities Act and the
     Exchange Act; and

          (iv)   furnish to any Holder forthwith upon request, so long as the
     Holder owns any Registrable Securities, (i) a written statement by the
     Company that it has complied with the reporting requirements of Rule 144
     promulgated under the Securities Act, the Securities Act and the Exchange
     Act, or that it qualifies as a registrant whose securities may be resold
     pursuant to a registration statement on Form S-3, (ii) a copy of the most
     recent annual or quarterly report of the Company and such other reports and
     documents

<PAGE>

     filed by the Company pursuant to the Securities Act or the
     Exchange Act, and (iii) such other information as may be reasonably
     requested in availing any Holder of any rule or regulation of the
     Commission that permits the selling of any Registrable Securities without
     registration or pursuant to a registration statement on Form S-3.

     3.   SHAREHOLDER OBLIGATIONS.  In connection with the filing of the
Registration Statement, each Holder will furnish to the Company as expeditiously
as possible, such documents or information with respect to itself and the
proposed sale or distribution of the Registrable Securities, as is reasonably
necessary in order to assure compliance of U.S. federal and applicable state
securities laws.  In addition, as a condition to any proposed sale or
distribution of the Registrable Securities, each Holder agrees that, in
connection with any proposed sale or distribution of Registrable Securities,
such Holder will comply with applicable prospectus delivery requirements, and
that such shares of Registrable Securities will be sold or distributed in
accordance with the method of sale set forth in the Registration Statement.

     4.   DELAYS IN REGISTRATION.

    (a)   The obligations of the Company with respect to the Registration
Statement (as set out in Section 2 hereof) and the rights of the Holders to
distribute the Registrable Securities pursuant to this Agreement and any
Registration Statement, may be suspended by the Company on the occurrence of any
of the following events:

          (i)    the Company has made an initial determination to conduct a
     primary, secondary or combined primary and secondary public offering
     pursuant to which Holders shall have the right to include therein
     Registrable Securities in accordance with Section 4(e) hereof;

          (ii)   the Company is about to make a normal course disclosure
     containing information of a material nature; or

          (iii)  the Company is engaged in any activity at any time that, in the
     good faith determination of its management or Board of Directors, would
     have a material effect on the Company and would be adversely affected by
     the continued compliance with this Agreement or the continued distribution
     of the Registrable Securities by the Holders (each a "MATERIAL ACTIVITY").

    (b)  In the event of a suspension pursuant to paragraph (a) of this 
Section 4, the Company shall use its best efforts to limit the length of 
such suspension to:

          (i)    under paragraph 4(a)(i), a period from the date of such
     determination until the earlier of (a) the decision by the Company not to
     pursue the public offering or (b) for a period of one hundred and twenty
     (120) days, more or less, from the effective date of the registration
     statement relating to such public offering, provided that during such
     suspension, the Company will proceed with reasonable best efforts to file
     the appropriate documentation in respect of, and otherwise complete, such
     public offering as expeditiously as practicable;

<PAGE>

          (ii)   under paragraph 4(a)(ii), to a period of five (5) Business
     Days, more or less; and

          (iii)  under paragraph 4(a)(iii), in the case of each Material
     Activity, for a period of sixty (60) days, more or less, and in any event
     to end not later than the termination of the Material Activity giving rise
     to the suspension.

     (c)  The Company shall promptly give the Holders' notice of both the
beginning and end of any suspension under subsection 4(a).

     (d)  To the extent that any suspension under paragraph 4(b)(i) or (iii)
occurs following the commencement of the Distribution Period, the Distribution
Period shall be extended by the length of such suspension.

     (e)  If  the Company at any time prior to the second anniversary of the
date of this Agreement proposes to conduct a public offering pursuant to Section
4(a)(i) hereof or proposes to file a Registration Statement on behalf of any
selling stockholder of the Company (except, in each case, with respect to
registration statements on Forms S-4, S-8 or another form not available for
registering the Registrable Securities for sale to the public), each such time
it will give written notice to all Holders of outstanding Registrable Securities
of its intention to do so at least fifteen (15) days prior to filing a
registration statement for such an offering. Upon the written request of any
such Holder, received by the Company within 15 Business Days after the giving of
any such notice by the Company, to register any of its Registrable Securities,
the Company will use reasonable best efforts to cause the Registrable Securities
as to which registration shall have been so requested to be included in the
securities to be covered by the registration statement proposed to be filed by
the Company.  If the Company is advised in writing in good faith by any managing
underwriter of the Common Stock being offered in such public offering that the
number of Common Stock proposed to be offered is greater than the amount which
can be offered without adversely affecting the offering, the Company may, at its
sole discretion, reduce the number of Registrable Securities included in the
offering, provided that the securities to be included in such an offering shall
first be allocated to the Company, then pro rata among the Holders and the
Rosetta Holders as a group, then to any other person seeking to include
securities in such offering.  Notwithstanding the foregoing provisions, the
Company may withdraw any registration statement referred to in this Section 4(e)
without thereby incurring any liability to the holders of Registrable
Securities.

     5.   UNDERWRITTEN OFFERINGS.

     (a)  If, in connection with any proposed distribution by the Holders under
Section 2 hereof, the Selling Holders shall request an underwriter pursuant to
Section 2(b)(viii) or if a Selling Holder wishes to include securities in an
underwritten offering pursuant to Section 4(e), then the right of any Selling
Holder to participate in such distribution shall be subject to the following
conditions:

<PAGE>

          (i)    the Selling Holder shall enter into, and perform its
     obligations under, an underwriting agreement in customary form with the
     managing underwriter selected for the underwriting;

          (ii)   during the course of such public offering, the Selling Holder
     shall cooperate with the Company and take such actions as are customarily
     required by underwriters in such circumstances;

          (iii)  during the period that any registration statement in respect of
     such public offering is effective, the Selling Holder shall make no other
     distribution of Registrable Securities; and

          (iv)   if the underwriters for the public offering of securities of
     the Company so request in writing of the Selling Holders and certain
     officers and directors of the Company, each Selling Holder shall agree not
     to sell publicly any or any other Common Stock of the Company (other than
     Registrable Securities or other Common Stock of the Company being
     registered in such offering), without the consent of such underwriters, for
     a period of not more than the lesser of (i) 180 days following the
     effective date of the registration statement relating to such offering, and
     (ii) the period during which the requested officers of the Company agree
     not to effect such sales.

     (b)  If the Company is advised in writing in good faith by any managing
underwriter of the Common Stock being offered in such public offering that the
number of shares of Common Stock proposed to be offered is greater than the
amount which can be offered without adversely affecting the offering, the
Company may, at its sole discretion, reduce the number of Registrable Securities
included in the offering, provided that the securities to be included in such an
offering shall first be allocated to the Company, then pro rata among the
Holders and the Rosetta Holders as a group, then to any other person seeking to
include securities in such offering.  If the Company is advised to decline to
include all or part of the Registrable Securities in such public offering, the
Distribution Period shall be extended by the aggregate of the suspension
initiated pursuant to Section 4(b)(i) hereof in respect of such public offering
and the period that the registration statement in respect of such public
offering is effective.

     6.   EXPENSES.

     (a)  The Company will pay all expenses in connection with the registration
of Registrable Securities effected by the Company pursuant to Section 2 or
Section 4(e) hereof (including, without limitation an underwritten offering made
pursuant to the provisions of Section 5 hereof) other than Selling Expenses. 
Holders of Registrable Securities registered pursuant to this Agreement shall
pay all Selling Expenses associated with such registration, with each Holder
bearing a pro rata portion of the Selling Expenses based upon the number of
Registrable Securities registered by each Holder.  The term "SELLING EXPENSE"
means all underwriting discounts and selling commissions and stock transfer fees
and taxes applicable to the sale of the Registrable Securities.

<PAGE>

     (b)  The expenses in connection with the registration of Registrable
Securities effected by the Company pursuant to Section 2 hereof include, without
limitation, all expenses incurred by the Company in complying with Section 2
hereof (including, without limitation an underwritten offering made pursuant to
the provisions of Section 5 hereof), including all registration and filing fees,
printing expenses, fees in connection with the listing of the Registrable
Securities with any securities exchange, fees and disbursements of counsel to
the Company and independent public accountants for the Company, fees and
expenses (including counsel fees) incurred in connection with complying with
state securities or "blue sky" laws, fees of the National Association of
Securities Dealers, Inc., transfer taxes, fees of transfer agents and
registrars; PROVIDED HOWEVER, that expenses payable by the Company with respect
to counsel for the Selling Holders shall be limited to not more than $15,000 in
fees (plus reasonable out of pocket expenses) of one special counsel for the
Selling Holders, who shall be reasonably acceptable to the Company.  The terms
of this Section 6 shall not require either party to pay any charges or amounts
for routine internal costs incurred by the other party in carrying out the
transfers contemplated in this Agreement.

     7.   SALE OF REGISTRABLE SECURITIES DURING THE DISTRIBUTION PERIOD.

     (a)  In order to assure compliance with the Securities Act, during any
Distribution Period the Company shall comply with either (i) or (ii) below:

          (i)    Except in the event that paragraph (ii) below applies, the
     Company shall (A) when and if deemed necessary by the Company, prepare and
     file with the Commission a post-effective amendment to the Registration
     Statement or a supplement to the related Prospectus or a supplement or
     amendment to any document incorporated therein by reference or file any
     other required document so that such Registration Statement will not
     contain an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, and so that, as thereafter delivered to purchasers
     of the Registrable Securities being sold thereunder, such Prospectus will
     not contain an untrue statement of a material fact or omit to state a
     material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading; (B) provide the Holders of Registrable Securities
     included in such Registration Statement copies of any documents filed
     pursuant to Section 7(a)(i)(A); and (C) if the Company has filed a post-
     effective amendment to the Registration Statement which has not yet been
     declared effective, the Company will notify each such Holder to that
     effect, and shall use its reasonable best efforts to secure the
     effectiveness of such post-effective amendment and shall immediately notify
     each such Holder when the amendment has become effective.

          (ii)   In the event of (A) any request by the Commission or any other
     federal or state governmental authority during the period of effectiveness
     of the Registration Statement for amendments or supplements to the
     Registration Statement or related Prospectus or for additional information;
     (B) the issuance by the Commission or any 

<PAGE>

     other federal or state governmental authority of any stop order suspending
     the effectiveness of the Registration Statement or the written threat or 
     initiation of any proceedings for that purpose; (C) the receipt by the 
     Company of any notification with respect to the suspension of the 
     qualification or exemption from qualification of any of the Registrable 
     Securities for sale in any jurisdiction or the initiation or threatening 
     of any proceeding for such purpose; (D) any event or circumstance which 
     necessitates the making of any changes in the Registration Statement or 
     Prospectus, or any document incorporated or deemed to be incorporated 
     therein by reference, so that, in the case of the Registration 
     Statement, it will not contain any untrue statement of a material fact 
     or any omission to state a material fact required to be stated therein 
     or necessary to make the statements therein not misleading, and that in 
     the case of the Prospectus, it will not contain any untrue statement of 
     a material fact or any omission to state a material fact required to be 
     stated therein or necessary to make the statements therein, in the light 
     of the circumstances under which they were made, not misleading; (E) 
     that, in accordance with Section 4(a)(i) hereof, the Company has made an 
     initial determination to conduct a public offering; (F) that, in 
     accordance with Section 4(a)(ii) hereof, the Company is in possession of 
     material information that it deems advisable not to disclose in a 
     Registration Statement or (G) that, in the good faith judgment of the 
     Company's Board of Directors, in accordance with the provision of 
     Section 4(a)(iii) hereof, it is advisable to suspend use of the 
     Prospectus for a period of time; then, subject to and in accordance with 
     Section 4 hereof, the Company shall deliver written notice to the 
     Holders to the effect of the foregoing and, upon receipt of such notice, 
     each such Holder's Distribution Period will not commence until such 
     Holder receives copies of the supplemented or amended Prospectus 
     provided for in Section 7(a)(i) hereof, or until it is advised in 
     writing by the Company, pursuant to Section 4(c) hereof, that the 
     Prospectus may be used, and has received copies of any additional or 
     supplemental filings that are incorporated or deemed incorporated by 
     reference in such Prospectus.

          (iii)  In the event any of the events or circumstances listed in the
     foregoing paragraph (ii) occur or exist after a Distribution Period has
     commenced, subject to Section 4 hereof, the Company shall have the same
     right to suspend such Distribution Period by delivery of written notice as
     the Company would have had if the Distribution Period had not yet
     commenced, and any such suspension of a Distribution Period shall be deemed
     included within the meaning of the term "suspension" for all purposes under
     this Agreement.

     (b)  The Holders selling securities pursuant to a Registration Statement
hereunder shall notify the Company in writing within three (3) Business Days
following each such sale and such notice shall include the number of shares
sold, the price of the sale and, if known to the Holder, the identity of the
purchaser.

     (c)  Each Holder who following the consummation of the transactions
contemplated by the Purchase Agreement will be an employee of the Company will
sell Registrable Securities only in accordance with the terms of the Company's
policy on insider trading.

<PAGE>

     (d)  The Holders will advise any broker or dealer acting on its behalf in
respect of the sale of the Registrable Securities, and any prospective
purchasers of the Registrable Securities, of the constraints set out in this
Section 7.

     8.   INDEMNIFICATION.

     (a)  The Company, will indemnify and hold harmless each Holder, the
officers, directors, partners, agents and employees of each Holder, any
underwriter and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act, against all losses, claims, damages or
liabilities, joint or several (collectively "CLAIMS"), to which they may become
subject under the Securities Act, the Exchange Act or other federal or state law
(excepting Claims related to or arising from a breach by such Holder of its
obligations under Sections 4(a), 5(a)(iii), or 7(b)), in so far as the Claims
(or actions in respect thereof) arise out of or are based on any of the
following (collectively, a "VIOLATION"): (i) any untrue statement or alleged
untrue statement of any material fact contained in the Registration Statement or
any amendment or supplement thereto, or the omission or alleged omission to
state in those documents a material fact required to be stated therein, or
necessary to make the statements therein, not misleading, (ii) any untrue
statement or alleged untrue statement of a material fact contained in any
preliminary Prospectus or the Prospectus or any amendment or supplement thereto,
or the omission or alleged omission to state in those documents a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; and (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
the Exchange Act or any state securities law; and reimburse each such Holder,
officer, director, partner, agent, employee, underwriter or controlling person
for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any Claims; PROVIDED HOWEVER, that the indemnity
agreement contained in this Section 8(a) shall not apply to amounts paid in
settlement of any such Claims, if such settlement is effected without the
consent of the Company, which consent shall not be unreasonably withheld,
conditioned or delayed.  This indemnity shall not apply to any Claims that arise
out of, or are based upon, an untrue statement or alleged untrue statement or
omission or alleged omission made in reliance upon and in conformity with
information provided by any such Holder in writing specifically for the purposes
of filing or maintaining the effectiveness of the Registration Statement.

     (b)  Each Holder will indemnify and hold harmless the Company, each of its
officers, directors, partners, agents or employees, each person, if any, who
controls the Company within the meaning of the Securities Act, any underwriter
and any other Holder or any of its directors, officers, partners, agents or
employees or any person who controls such Holder, against any Claims to which
the Company or any such director, officer, partner, agent, employee, controlling
person or underwriter, or other such Holder or director, officer, partner,
agent, employee or controlling person may become subject, under the Securities
Act, the Exchange Act or other federal or state law, insofar as such Claims
arise out of or are based upon (i) any Violation, in each case to the extent
(and only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by such Holder expressly for use
in connection with such registration, or (ii) the failure of such Holder to (A)
comply with applicable prospectus 

<PAGE>

delivery requirements, or (B) effect each sale by such Holder of Registrable 
Securities included in the Registration Statement in accordance with the 
method of sale set forth in the Registration Statement. In addition, each 
such Holder will reimburse any reasonable legal or other expenses reasonably 
incurred by the Company or any such director, officer, partner, agent, 
employee, controlling person or underwriter, other Holder, officer, director, 
partner, agent, employee or controlling person in connection with 
investigating or defending any such Claims.  Notwithstanding anything 
contained in this Agreement to the contrary, the indemnity agreement 
contained in this Section 8(b) shall not apply to amounts paid in settlement 
of any such Claims if such settlement is effected without the consent of the 
Holder, which consent shall not be unreasonably withheld, conditioned or 
delayed; PROVIDED FURTHER, that the aggregate liability of each Holder in 
connection with any sale of Registrable Securities pursuant to a Registration 
Statement in which a Violation occurred shall be limited to the net proceeds 
received by such Holder from such sale.

    (c)   As soon as it becomes aware of the commencement of an action
respecting a Claim, the indemnified party shall promptly notify the indemnifying
party, although failure to notify shall not relieve the indemnifying party from
any liability to indemnify the indemnified party.  Following receipt of that
notice, the indemnifying party may participate in and, to the extent it wishes
and upon giving notice to the indemnified party, assume and undertake the
defense of the action using counsel satisfactory to it; provided that, if the
indemnified party includes more than one Holder,  such counsel shall be satisfy
to the Holders of a majority of the Registrable Securities held by all such
indemnified Holders.  In that event, the indemnifying party will not be liable
to the indemnified party for any legal expenses subsequently incurred by the
indemnified party in connection with the defense of the action, other than
reasonable costs of investigation and of liaison with the indemnifying party's
counsel.  Notwithstanding the foregoing, an indemnified party shall have the
right to retain its own counsel, with reasonable fees and expenses to be paid by
the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding.

     (d)  If the indemnification provided for above is held by a court of
competent jurisdiction to be unavailable, then the indemnifying party, in lieu
of such indemnification, shall contribute to the amount paid or payable by the
indemnified party in such proportion as is appropriate to reflect the relative
fault of the indemnifying party on the one hand and the indemnified party on the
other hand in connection with the statements or omissions that resulted in the
Claims, as well as other equitable considerations.  The relative fault of the
parties shall be determined by reference to, among other things, whether the
alleged untrue statement of a material fact or omission to state a material fact
relates to information supplied by the indemnifying party or the indemnified
party and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

     (e)  The indemnity agreements of the Company and the Holders set forth in
this Section 8 are subject to the condition that, insofar as they relate to any
Violation made in a preliminary Prospectus but eliminated or remedied in the
amended Prospectus on file with the 

<PAGE>

Commission at the time the Registration Statement in question becomes 
effective or the amended Prospectus filed with the Commission pursuant to 
Commission Rule 424(b) (the "Final Prospectus"), such indemnity agreement 
shall not inure to the benefit of any person if a copy of the Final 
Prospectus was furnished to the indemnified party and was not furnished to 
the person asserting the Claim at or prior to the time such action is 
required by the Securities Act.

     (f)  The provisions of this Section 8 shall survive the expiration or
termination of this Agreement and shall expire at the end of any applicable
limitation period.

     9.   EXPIRATION OF REGISTRATION RIGHTS.

    The obligations of the Company under Section 2 of this Agreement to register
the Registrable Securities shall expire and terminate upon the earlier of (i)
the second anniversary of the date of this Agreement; or (ii) at such time when
the Holders have sold the last of the Registrable Securities; provided, however,
that such obligations shall be extended until the last day of the Distribution
Period, if the Distribution Period has commenced on or prior to, and is
suspended on or has not expired by, the date on which such obligations would
otherwise expire.

     10.  RESTRICTIONS ON TRANSFERS OF COMMON SHARES.

     The Holders agree and understand that the issuance of the Registrable
Securities has not been, and, except as contemplated in this Agreement, the sale
or other disposition thereof by the Holders will not be, registered under the
Securities Act or the securities laws of any state and that such shares may be
sold or disposed of only in one or more transactions registered under the
Securities Act and, where applicable, such state laws or as to which an
exemption from the registration requirements of the Securities Act and, where
applicable, such state laws is available.  The Holders acknowledge that, except
as expressly set forth in this Agreement, the Holders have no right to require
the Company to cause the registration of any Registrable Securities.  The
Holders understand and agree that each certificate representing any Registrable
Securities (each, a "CERTIFICATE") shall be subject to stop transfer
instructions and shall bear the following legend:

                 "THE COMMON SHARES REPRESENTED BY THIS CERTIFICATE
          HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT
          BE SOLD OR DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE
          REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE
          SECURITIES LAWS OR AN EXEMPTION FROM THE REGISTRATION
          REQUIREMENTS OF SUCH ACT AND SUCH STATE LAWS."

     The Company hereby agrees that it will, upon the request of the Holders,
eliminate any stop transfer instructions and any restrictive legend on any
certificates representing the Registrable Securities if (i) in the opinion of
counsel, including in-house counsel with demonstrated expertise in matters
relating to federal securities laws, which counsel and opinion 

<PAGE>

(in form, scope and substance) shall be reasonably satisfactory to the 
Company, the Holders are entitled to sell or dispose of the Registrable 
Securities represented by such Certificate without registration; (ii) such 
shares are being disposed of by the Holders under a Registration Statement 
pursuant to Section 2 herein and in compliance with the Securities Act and 
applicable state and securities laws; or (iii) the Holder has held the 
Registrable Securities for at least two years and has not been an affiliate 
of the Company for at least three months and represents to the Company in 
writing that the Holder is, therefore, eligible to resell such Registrable 
Securities pursuant to Rule 144(k) under the Securities Act.

     11.  BINDING ON SUCCESSORS.  This Agreement is binding upon and shall 
inure to the benefit of the respective successors and assigns of the parties, 
whether so expressed or not.

     12.  NO ASSIGNMENT.  No Holder may assign this Agreement or any of the 
rights or obligations hereunder without the express written consent of the 
Company; provided, however, that this Agreement and the rights and 
obligations of the Holders may be assigned with the prior written consent of 
the Company, which shall not be unreasonably withheld, (i) if the Holder is 
an individual, to an immediate family member, (ii) if the Holder is a limited 
partnership, to its limited partners, (iii) if the Holder is a corporation, 
to its stockholders, and (iv) if the Holder is a limited liability company, 
to its members, and on condition that such transferee pursuant to clauses 
(i), (ii), (iii) or (iv) agrees in writing to be bound by the terms of this 
Agreement.

     13.  NOTICE.  All notices, requests, consents or other communications
required pursuant to this Agreement shall be in writing and shall be delivered

consent of the Company and the Holders of a majority of the Registrable
Securities then outstanding.  The failure of a party to enforce any right set

     Initiating Holders, and to keep such Registration Statement continuously
     effective until the earlier of (A) midnight on the sixtieth (60th) day
     following the Effective Date of the Registration, or at such later time as
     may be established pursuant to Sections 4(d), 5(b) or 7(a) or (B) the date

     and the Prospectus, as may be necessary to keep the Registration Statement
     effective during a Distribution Period;

          (iv)   furnish to each Selling Holder such number of copies of the

     Registrable Securities under the state securities or "blue sky" laws of
     such jurisdictions as each Selling Holder shall reasonably request and to
     maintain such qualification throughout the Distribution Period, except that
     the Company shall not be required for the purpose of such qualification to
     qualify generally to transact business as a foreign corporation in any

                                       3

<PAGE>

     jurisdiction where it is not so qualified or, except as to matters relating
     to the offer and sale of the Registrable Securities, consent to general
     service of process in any such jurisdiction;

          (vi)   immediately notify each Selling Holder who elected to include
     Registrable Securities in the Registration Statement (A) of the Effective
     Date and the date when any post-effective amendment to the Registration
     Statement becomes effective, (B) of any stop order or notification from the
     Commission or any other jurisdiction as to the suspension of the
     effectiveness of the Registration Statement, and (C) of the happening of
     any event of which the Company has knowledge that would result in the
     Prospectus contained in the Registration Statement, as then in effect,

     material fact required to be stated therein or necessary to make the
     statements therein not misleading in light of the circumstances then
     existing;

          (vii)  timely file with the Commission all documents required to be
     filed by the Company pursuant to subsections 13(a), 13(c), 15(d), and
     Section 14 of the Exchange Act, and otherwise maintain its qualification to
     file a Registration Statement; and

          (viii) if the holders of a majority of the Registrable Securities to
     be registered on the Registration Statement so request on their notices to
     the Company requesting registration, the Company shall use its reasonable
     best efforts to secure an investment banking firm of the Company's choice
     to act as underwriter, subject to the approval of the holders of a majority
     of the Registrable Securities to be registered on the Registration
     Statement, which approval shall not be unreasonably withheld, to retain one
     or more underwriters (on either a "firm commitment" or "best efforts"
     basis); provided that, if the Company is unable to secure a commitment from
     such an underwriter within 30 days following receipt of the Registration
     Notice, the Selling Holders may select one or more nationally recognized
     underwriters (on either a "firm commitment" or "best efforts" basis),
     subject to the approval of the Company, which approval shall not be
     unreasonably withheld;

          (ix)   if the Selling Holders request an underwriter pursuant to
     paragraph above, the Company shall take all reasonable actions as are
     necessary or advisable to expedite and facilitate the disposition of the
     Registrable Securities in the manner contemplated by the Registration
     Statement, to the same extent as if the Registrable Securities then being
     offered were for the account of the Company, including, without limitation,
     (A) entering into such customary agreements (including underwriting
     agreements in customary form) as the underwriters may reasonably request,
     and  (B) using its best efforts to furnish: (1) an opinion of counsel
     representing the Company for the purposes of such registration, dated the
     date the Registrable Securities are delivered to the underwriters for sale
     and addressed to the underwriters and the Selling Holders, (x) stating that
     the Registration Statement has become effective under the Securities Act,
     and that to the best knowledge of such counsel, no stop order suspending
     its effectiveness has been issued and no proceeding for that purpose has
     been instituted or is pending or contemplated under the Securities Act, (y)
     stating that the Registration Statement and each amendment or

                                       4

<PAGE>

     supplement thereto, comply as to form in all material respects with the 
     requirements of the Securities Act (except that such counsel need not 
     express any opinion as to financial statements contained therein) and 
     (z) to such other effects as reasonably may be requested by counsel for 
     the underwriters, (2) letters dated the date of execution of the 
     underwriting agreement and the date of delivery of the Registrable 
     Securities (if so requested by the underwriters) and addressed to the 
     underwriters and the Selling Holders, from the independent public 
     accountants retained by the Company stating that they are independent 
     public accountants within the meaning of the Securities Act that, in the 
     opinion of those accountants, the financial statements of the Company 
     included in the Registration Statement, and any amendment or supplement 
     thereto, comply as to form in all material respects with the applicable 
     accounting requirements of the Securities Act, and covering such other 
     financial matters (including information as to the period ending no more 
     than five (5) business days prior to the date of the letter) with 
     respect to the registration as the underwriters reasonably may request, 
     and (3) for inspection by any underwriter participating in any 
     distribution pursuant to the Registration Statement, and any attorney, 
     accountant or other agent retained by any underwriter, all pertinent 
     financial and other records, pertinent corporate documents and 
     properties of the Company, and causing the Company' officers, directors 
     and employees to supply all information reasonably requested by any 
     underwriter, attorney, and accountant or agent in connection with the 
     Registration Statement, on the condition that each of the foregoing have 
     entered into confidentiality agreements with the Company in respect of 
     the information contained in such records or documents.

     (c)  Except as provided in paragraph (d) below, the Company shall not be
required to effect more than one (1) registration pursuant to the provisions of
this Section 2.  In addition, the Company may effect qualification and
registration of the Registrable Securities pursuant to this Section 2 pursuant
to an existing shelf registration statement or pursuant to an underwritten
offering in accordance with the provisions of Section 5 hereof.

     (d)  If (i) as a result of a material adverse change in the business,
financial results or operations of the Company occurring after a request for
registration pursuant to this Section 2, the Registration Statement is either
not made effective or withdrawn, at the request of the Selling Holders or
otherwise, before all of the Registrable Securities included thereunder have
been sold, or (ii) the number of shares of Registrable Securities to be included
in an offering pursuant to this Section 2 is reduced by more than 25% pursuant
to Section 5(b), then the Selling Holders shall have the right to request that
the Company effect one (1) additional registration pursuant to and in accordance
with the terms of this Section 2.

     (e)  With a view toward making available to Holders the benefits of Rule
144 promulgated under the Securities Act and any other rule or regulation of the
Commission that may at any time permit a Holder to sell Registrable Securities
without registration or pursuant to a registration statement on Form S-3, the
Company agrees to:

          (i)    make and keep public information available, as those terms are
     understood and defined in Rule 144 promulgated under the Securities Act, at
     all times;

                                       5

          (ii)   take such reasonable action as is necessary to maintain the
     ability of the Holders to utilize Form S-3 for the sale of their
     Registrable Securities;

          (iii)  file with the Commission in a timely manner all reports and
     other documents required of the Company under the Securities Act and the
     Exchange Act; and

          (iv)   furnish to any Holder forthwith upon request, so long as the
     Holder owns any Registrable Securities, (i) a written statement by the
     Company that it has complied with the reporting requirements of Rule 144
     promulgated under the Securities Act, the Securities Act and the Exchange
     Act, or that it qualifies as a registrant whose securities may be resold
     pursuant to a registration statement on Form S-3, (ii) a copy of the most
     recent annual or quarterly report of the Company and such other reports and
     documents filed by the Company pursuant to the Securities Act or the
     Exchange Act, and (iii) such other information as may be reasonably
     requested in availing any Holder of any rule or regulation of the
     Commission that permits the selling of any Registrable Securities without
     registration or pursuant to a registration statement on Form S-3.

     3.   SHAREHOLDER OBLIGATIONS.  In connection with the filing of the
Registration Statement, each Holder will furnish to the Company as expeditiously
as possible, such documents or information with respect to itself and the
proposed sale or distribution of the Registrable Securities, as is reasonably
necessary in order to assure compliance of U.S. federal and applicable state
securities laws.  In addition, as a condition to any proposed sale or
distribution of the Registrable Securities, each Holder agrees that, in
connection with any proposed sale or distribution of Registrable Securities,
such Holder will comply with applicable prospectus delivery requirements, and
that such shares of Registrable Securities will be sold or distributed in
accordance with the method of sale set forth in the Registration Statement.

     4.  DELAYS IN REGISTRATION.

    (a)   The obligations of the Company with respect to the Registration
Statement (as set out in Section 2 hereof) and the rights of the Holders to
distribute the Registrable Securities pursuant to this Agreement and any
Registration Statement, may be suspended by the Company on the occurrence of any
of the following events:

          (i)    the Company has made an initial determination to conduct a
     primary, secondary or combined primary and secondary public offering
     pursuant to which Holders shall have the right to include therein
     Registrable Securities in accordance with Section 4(e) hereof;

          (ii)   the Company is about to make a normal course disclosure
     containing information of a material nature; or

          (iii)  the Company is engaged in any activity at any time that, in the
     good faith determination of its management or Board of Directors, would
     have a material effect on the Company and would be adversely affected by
     the continued compliance with this Agreement or the continued distribution
     of the Registrable Securities by the Holders (each a "MATERIAL ACTIVITY").

                                       6

<PAGE>

     (b)  In the event of a suspension pursuant to paragraph (a) of this Section
4, the Company shall use its best efforts to limit the length of such suspension
to:

          (i)    under paragraph 4(a)(i), a period from the date of such
     determination until the earlier of (a) the decision by the Company not to
     pursue the public offering or (b) for a period of one hundred and twenty
     (120) days, more or less, from the effective date of the registration
     statement relating to such public offering, provided that during such
     suspension, the Company will proceed with reasonable best efforts to file
     the appropriate documentation in respect of, and otherwise complete, such
     public offering as expeditiously as practicable;

          (ii)   under paragraph 4(a)(ii), to a period of five (5) Business
     Days, more or less; and

          (iii)  under paragraph 4(a)(iii), in the case of each Material
     Activity, for a period of sixty (60) days, more or less, and in any event
     to end not later than the termination of the Material Activity giving rise
     to the suspension.

     (c)  The Company shall promptly give the Holders' notice of both the
beginning and end of any suspension under subsection 4(a).

     (d)  To the extent that any suspension under paragraph 4(b)(i) or (iii)
occurs following the commencement of the Distribution Period, the Distribution
Period shall be extended by the length of such suspension.

     (e)  If  the Company at any time prior to the second anniversary of the 
date of this Agreement proposes to conduct a public offering pursuant to 
Section 4(a)(i) hereof or proposes to file a Registration Statement on behalf 
of any selling stockholder of the Company (except, in each case, with respect 
to registration statements on Forms S-4, S-8 or another form not available 
for registering the Registrable Securities for sale to the public), each such 
time it will give written notice to all Holders of outstanding Registrable 
Securities of its intention to do so at least fifteen (15) days prior to 
filing a registration statement for such an offering. Upon the written 
request of any such Holder, received by the Company within 15 Business Days 
after the giving of any such notice by the Company, to register any of its 
Registrable Securities, the Company will use reasonable best efforts to cause 
the Registrable Securities as to which registration shall have been so 
requested to be included in the securities to be covered by the registration 
statement proposed to be filed by the Company.  If the Company is advised in 
writing in good faith by any managing underwriter of the Common Stock being 
offered in such public offering that the number of Common Stock proposed to 
be offered is greater than the amount which can be offered without adversely 
affecting the offering, the Company may, at its sole discretion, reduce the 
number of Registrable Securities included in the offering, provided that the 
securities to be included in such an offering shall first be allocated to the 
Company, then pro rata among the Holders and the Cimtech Holders as a group, 
then to any other person seeking to include securities in such offering.  
Notwithstanding the foregoing provisions, the Company may withdraw any 
registration statement referred to in this Section 4(e) without thereby 
incurring any liability to the holders of Registrable Securities.

     5.   UNDERWRITTEN OFFERINGS.

     (a)  If, in connection with any proposed distribution by the Holders under
Section 2 hereof, the Selling Holders shall request an underwriter pursuant to
Section 2(b)(viii) or if a Selling Holder wishes to include securities in an
underwritten offering pursuant to Section 4(e), then the right of any Selling
Holder to participate in such distribution shall be subject to the following
conditions:

          (i)    the Selling Holder shall enter into, and perform its
     obligations under, an underwriting agreement in customary form with the
     managing underwriter selected for the underwriting;

          (ii)   during the course of such public offering, the Selling Holder
     shall cooperate with the Company and take such actions as are customarily
     required by underwriters in such circumstances;

          (iii)  during the period that any registration statement in respect of
     such public offering is effective, the Selling Holder shall make no other
     distribution of Registrable Securities; and

          (iv)   if the underwriters for the public offering of securities of
     the Company so request in writing of the Selling Holders and certain
     officers and directors of the Company, each Selling Holder shall agree not
     to sell publicly any or any other Common Stock of the Company (other than
     Registrable Securities or other Common Stock of the Company being
     registered in such offering), without the consent of such underwriters, for
     a period of not more than the lesser of (i) 180 days following the
     effective date of the registration statement relating to such offering, and
     (ii) the period during which the requested officers of the Company agree
     not to effect such sales.

     (b)  If the Company is advised in writing in good faith by any managing
underwriter of the Common Stock being offered in such public offering that the
number of shares of Common Stock proposed to be offered is greater than the
amount which can be offered without adversely affecting the offering, the
Company may, at its sole discretion, reduce the number of Registrable Securities
included in the offering, provided that the securities to be included in such an
offering shall first be allocated to the Company, then pro rata among the
Holders and the Cimtech Holders as a group, then to any other person seeking to
include securities in such offering.  If the Company is advised to decline to
include all or part of the Registrable Securities in such public offering, the
Distribution Period shall be extended by the aggregate of the suspension
initiated pursuant to Section 4(b)(i) hereof in respect of such public offering
and the period that the registration statement in respect of such public
offering is effective.

     6.  EXPENSES.

     (a)  The Company will pay all expenses in connection with the registration
of Registrable Securities effected by the Company pursuant to Section 2 or

     therein not misleading, and so that, as thereafter delivered to purchasers
     of the Registrable Securities being sold thereunder, such Prospectus will

     material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading; (B) provide the Holders of Registrable Securities

     declared effective, the Company will notify each such Holder to that
     effect, and shall use its reasonable best efforts to secure the
     effectiveness of such post-effective amendment and shall immediately notify

     required to be stated therein or necessary to make the statements therein
     not misleading, and that in the case of the Prospectus, it will not contain
     any untrue statement of a material fact or any omission to state a material

          (iii)     In the event any of the events or circumstances listed in
     the foregoing paragraph (ii) occur or exist after a Distribution Period has
     commenced, subject to Section 4 hereof, the Company shall have the same
     right to suspend such Distribution Period by delivery of written notice as
     the Company would have had if the Distribution Period had not yet
     commenced, and any such suspension of a Distribution Period shall be deemed
     included within the meaning of the term "suspension" for all purposes under
     this Agreement.

     (b)  The Holders selling securities pursuant to a Registration Statement 
hereunder shall notify the Company in writing within three (3) Business Days 
following each such sale and such notice shall include the number of shares 
sold, the price of the sale and, if known to the Holder, the identity of the 
purchaser.

                                       10

     (c)  Each Holder who following the consummation of the transactions 
contemplated by the Purchase Agreement will be an employee of the Company 
will sell Registrable Securities only in accordance with the terms of the 
Company's policy on insider trading.

     (d)  The Holders will advise any broker or dealer acting on its behalf in
respect of the sale of the Registrable Securities, and any prospective
purchasers of the Registrable Securities, of the constraints set out in this
Section 7.

     8.   INDEMNIFICATION.

     (a)  The Company, will indemnify and hold harmless each Holder, the 
officers, directors, partners, agents and employees of each Holder, any 
underwriter and each person, if any, who controls such Holder or underwriter 
within the meaning of the Securities Act, against all losses, claims, damages 
or liabilities, joint or several (collectively "CLAIMS"), to which they may 
become subject under the Securities Act, the Exchange Act or other federal or 
state law (excepting Claims related to or arising from a breach by such 
Holder of its obligations under Sections 4(a), 5(a)(iii), or 7(b)), in so far 
as the Claims (or actions in respect thereof) arise out of or are based on 
any of the following (collectively, a "VIOLATION"): (i) any untrue statement 
or alleged untrue statement of any material fact contained in the 
Registration Statement or any amendment or supplement thereto, or the 
omission or alleged omission to state in those documents a material fact 
required to be stated therein, or necessary to make the statements therein, 
not misleading, (ii) any untrue statement or alleged untrue statement of a 
material fact contained in any preliminary Prospectus or the Prospectus or 
any amendment or supplement thereto, or the omission or alleged omission to 
state in those documents a material fact necessary to make the statements 
therein, in light of the circumstances under which they were made, not 
misleading; and (iii) any violation or alleged violation by the Company of 
the Securities Act, the Exchange Act, any state securities law or any rule or 
regulation promulgated under the Securities Act, the Exchange Act or any 
state securities law; and reimburse each such Holder, officer, director, 
partner, agent, employee, underwriter or controlling person for any legal or 
other expenses reasonably incurred by them in connection with investigating 
or defending any Claims; PROVIDED HOWEVER, that the indemnity agreement 
contained in this Section 8(a) shall not apply to amounts paid in settlement 
of any such Claims, if such settlement is effected without the consent of the 
Company, which consent shall not be unreasonably withheld, conditioned or 
delayed.  This indemnity shall not apply to any Claims that arise out of, or 
are based upon, an untrue statement or alleged untrue statement or omission 
or alleged omission made in reliance upon and in conformity with information 
provided by any such Holder in writing specifically for the purposes of 
filing or maintaining the effectiveness of the Registration Statement.

     (b)  Each Holder will indemnify and hold harmless the Company, each of its
officers, directors, partners, agents or employees, each person, if any, who
controls the Company within the meaning of the Securities Act, any underwriter
and any other Holder or any of its directors, officers, partners, agents or
employees or any person who controls such Holder, against any Claims to which
the Company or any such director, officer, partner, agent, employee, controlling
person or underwriter, or other such Holder or director, officer, partner,
agent, employee or controlling person may become subject, under the Securities
Act, the Exchange Act or other federal or state law, insofar as such Claims
arise out of or are based upon (i) any Violation, in

                                       11

<PAGE>

each case to the extent (and only to the extent) that such Violation occurs 
in reliance upon and in conformity with written information furnished by such 
Holder expressly for use in connection with such registration, or (ii) the 
failure of such Holder to (A) comply with applicable prospectus delivery 
requirements, or (B) effect each sale by such Holder of Registrable 
Securities included in the Registration Statement in accordance with the 
method of sale set forth in the Registration Statement. In addition, each 
such Holder will reimburse any reasonable legal or other expenses reasonably 
incurred by the Company or any such director, officer, partner, agent, 
employee, controlling person or underwriter, other Holder, officer, director, 
partner, agent, employee or controlling person in connection with 
investigating or defending any such Claims.  Notwithstanding anything 
contained in this Agreement to the contrary, the indemnity agreement 
contained in this Section 8(b) shall not apply to amounts paid in settlement 
of any such Claims if such settlement is effected without the consent of the 
Holder, which consent shall not be unreasonably withheld, conditioned or 
delayed; PROVIDED FURTHER, that the aggregate liability of each Holder in 
connection with any sale of Registrable Securities pursuant to a Registration 
Statement in which a Violation occurred shall be limited to the net proceeds 
received by such Holder from such sale.

    (c)   As soon as it becomes aware of the commencement of an action 
respecting a Claim, the indemnified party shall promptly notify the 
indemnifying party, although failure to notify shall not relieve the 
indemnifying party from any liability to indemnify the indemnified party.  
Following receipt of that notice, the indemnifying party may participate in 
and, to the extent it wishes and upon giving notice to the indemnified party, 
assume and undertake the defense of the action using counsel satisfactory to 
it; provided that, if the indemnified party includes more than one Holder,  
such counsel shall be satisfy to the Holders of a majority of the Registrable 
Securities held by all such indemnified Holders.  In that event, the 
indemnifying party will not be liable to the indemnified party for any legal 
expenses subsequently incurred by the indemnified party in connection with 
the defense of the action, other than reasonable costs of investigation and 
of liaison with the indemnifying party's counsel.  Notwithstanding the 
foregoing, an indemnified party shall have the right to retain its own 
counsel, with reasonable fees and expenses to be paid by the indemnifying 
party, if representation of such indemnified party by the counsel retained by 
the indemnifying party would be inappropriate due to actual or potential 
differing interests between such indemnified party and any other party 
represented by such counsel in such proceeding.

     (d)  If the indemnification provided for above is held by a court of 
competent jurisdiction to be unavailable, then the indemnifying party, in 
lieu of such indemnification, shall contribute to the amount paid or payable 
by the indemnified party in such proportion as is appropriate to reflect the 
relative fault of the indemnifying party on the one hand and the indemnified 
party on the other hand in connection with the statements or omissions that 
resulted in the Claims, as well as other equitable considerations.  The 
relative fault of the parties shall be determined by reference to, among 
other things, whether the alleged untrue statement of a material fact or 
omission to state a material fact relates to information supplied by the 
indemnifying party or the indemnified party and the parties' relative intent, 
knowledge, access to information and opportunity to correct or prevent such 
statement or omission.

                                       12

<PAGE>

     (e)  The indemnity agreements of the Company and the Holders set forth 
in this Section 8 are subject to the condition that, insofar as they relate 
to any Violation made in a preliminary Prospectus but eliminated or remedied 
in the amended Prospectus on file with the Commission at the time the 
Registration Statement in question becomes effective or the amended 
Prospectus filed with the Commission pursuant to Commission Rule 424(b) (the 
"Final Prospectus"), such indemnity agreement shall not inure to the benefit 
of any person if a copy of the Final Prospectus was furnished to the 
indemnified party and was not furnished to the person asserting the Claim at 
or prior to the time such action is required by the Securities Act.

     (f)  The provisions of this Section 8 shall survive the expiration or 
termination of this Agreement and shall expire at the end of any applicable 
limitation period.

     9.   EXPIRATION OF REGISTRATION RIGHTS.

    The obligations of the Company under Section 2 of this Agreement to 
register the Registrable Securities shall expire and terminate upon the 
earlier of (i) the second anniversary of the date of this Agreement; or (ii) 
at such time when the Holders have sold the last of the Registrable 
Securities; provided, however, that such obligations shall be extended until 
the last day of the Distribution Period, if the Distribution Period has 
commenced on or prior to, and is suspended on or has not expired by, the date 
on which such obligations would otherwise expire.

     10.  RESTRICTIONS ON TRANSFERS OF COMMON SHARES.

     The Holders agree and understand that the issuance of the Registrable 
Securities has not been, and, except as contemplated in this Agreement, the 
sale or other disposition thereof by the Holders will not be, registered 
under the Securities Act or the securities laws of any state and that such 
shares may be sold or disposed of only in one or more transactions registered 
under the Securities Act and, where applicable, such state laws or as to 
which an exemption from the registration requirements of the Securities Act 
and, where applicable, such state laws is available.  The Holders acknowledge 
that, except as expressly set forth in this Agreement, the Holders have no 
right to require the Company to cause the registration of any Registrable 
Securities.  The Holders understand and agree that each certificate 
representing any Registrable Securities (each, a "CERTIFICATE") shall be 
subject to stop transfer instructions and shall bear the following legend:

               "THE COMMON SHARES REPRESENTED BY THIS CERTIFICATE HAVE
          NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
          AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE
          SOLD OR DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE
          REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE
          SECURITIES LAWS OR AN EXEMPTION FROM THE REGISTRATION
          REQUIREMENTS OF SUCH ACT AND SUCH STATE LAWS."

                                       13

<PAGE>

     The Company hereby agrees that it will, upon the request of the Holders, 
eliminate any stop transfer instructions and any restrictive legend on any 
certificates representing the Registrable Securities if (i) in the opinion of 
counsel, including in-house counsel with demonstrated expertise in matters 
relating to federal securities laws, which counsel and opinion (in form, 
scope and substance) shall be reasonably satisfactory to the Company, the 
Holders are entitled to sell or dispose of the Registrable Securities 
represented by such Certificate without registration; (ii) such shares are 
being disposed of by the Holders under a Registration Statement pursuant to 
Section 2 herein and in compliance with the Securities Act and applicable 
state and securities laws; or (iii) the Holder has held the Registrable 
Securities for at least two years and has not been an affiliate of the 
Company for at least three months and represents to the Company in writing 
that the Holder is, therefore, eligible to resell such Registrable Securities 
pursuant to Rule 144(k) under the Securities Act.

     11.  BINDING ON SUCCESSORS.  This Agreement is binding upon and shall 
inure to the benefit of the respective successors and assigns of the parties, 
whether so expressed or not.

     12.  NO ASSIGNMENT.  No Holder may assign this Agreement or any of the 
rights or obligations hereunder without the express written consent of the 
Company; provided, however, that this Agreement and the rights and 
obligations of the Holders may be assigned with the prior written consent of 
the Company, which shall not be unreasonably withheld, (i) if the Holder is 
an individual, to an immediate family member, (ii) if the Holder is a limited 
partnership, to its limited partners, (iii) if the Holder is a corporation, 
to its stockholders, and (iv) if the Holder is a limited liability company, 
to its members, and on condition that such transferee pursuant to clauses 
(i), (ii), (iii) or (iv) agrees in writing to be bound by the terms of this 
Agreement.

     13.  NOTICE.  All notices, requests, consents or other communications 
required pursuant to this Agreement shall be in writing and shall be 
delivered personally, mailed by certified or registered mail (return receipt 
requested), or sent by facsimile addressed as follows:

of law principles).

     15.  AMENDMENT.  This Agreement may not be amended without the written 
consent of the Company and the Holders of a majority of the Registrable 
Securities then outstanding.  The failure of a party to enforce any right set 
forth in this Agreement, or granted at law or in equity, shall in no way be 
construed to be a waiver of such right, or affect the validity of this 
Agreement or any part thereof, or the right thereafter to enforce each and 
every provision of this Agreement.

     16.  UNENFORCEABLE PROVISION.  If any provision of this Agreement is 
held to be illegal, invalid, or unenforceable, such provision shall be 
severed from this Agreement and shall not in any manner affect or render 
illegal, invalid or unenforceable any other provision of this Agreement.

     17.  COUNTERPARTS.  This Agreement may be executed in two or more 
counterparts, each of which shall be deemed to be an original and all of 
which together shall constitute one and the same instrument.
