            Notes to the Condensed Consolidated Financial Statements
                                   (Unaudited)

Note 1--Introduction:

        The accompanying unaudited condensed consolidated financial statements
of Showscan Entertainment Inc. (the "Company") have been prepared in accordance
with generally accepted accounting principles for interim financial information
and with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the three-month period and the nine-month period ended
December 31, 1997 are not necessarily indicative of the results that may be
expected either for any other quarter in the fiscal year ending March 31, 1998
or for the entire fiscal year ended March 31, 1998. For further information,
refer to the consolidated financial statements and footnotes thereto included in
the Company's annual report on Form 10-K for the year ended March 31, 1997.

Note 2--Merger:

        On August 4, 1997, the Company entered into an Agreement and Plan of
Reorganization by and among the Company, Iwerks Entertainment, Inc. ("Iwerks")
and IWK-1 Merger Corporation ("Merger Sub"), as amended by that certain
Amendment No. 1 to Agreement and Plan of Reorganization dated December 29, 1997
(the "Merger Agreement"), pursuant to which Merger Sub will be merged (the
"Merger") with and into the Company. As a result of the Merger, (a) each share
of the Company's common stock, $.001 par value (the "Common Stock"), which is
outstanding immediately prior to the Merger shall be converted into .62 shares
of Iwerks' common stock, $.001 par value ("Iwerks Common Stock"), and (b) each
share of Series C Convertible Preferred Stock will be converted into the right
to receive shares of Iwerks Common Stock in an amount equal to the number of
shares of Common Stock into which such share of Series C Convertible Preferred
Stock is convertible immediately prior to the Merger multiplied by .62. The
December, 1997 amendment of the Merger Agreement, among other things, reduced
the exchange ratio from .85 to .62. As a result of the Merger, the Company will
become a wholly-owned subsidiary of Iwerks and the shares of Common Stock will
cease to be publicly traded. Consummation of the Merger is subject to certain
conditions, including certain approvals by the stockholders of both the Company
and Iwerks. The Merger and other conditions to the effectiveness thereof are
more fully described in the Company's Current Reports on Form 8-K dated August
4, 1997 and December 29, 1997 on file with the Securities and Exchange
Commission. The Company currently anticipates holding a stockholder meeting (and
that the Merger will close) in March, 1998. On February 3, 1998, Ridefilm
Corporation, a wholly-owned subsidiary of Imax Corporation, filed suit against
Iwerks in the United States District Court for the Southern District of New
York. This lawsuit, among other things, seeks to enjoin the Merger under various
antitrust claims. Ridefilm is seeking a preliminary injunction of the Merger as
well. The Company and Iwerks believe that the suit is without merit and are
vigorously defending these claims and are opposing the request for preliminary
injunction.

Note 3--Owned and Operated theatres:

        The Company retains an ownership interest in selected Showscan motion
simulation theatre attractions ("Showscan Attractions") through various joint
venture arrangements. The Company currently operates and/or has an ownership
interest in Showscan Attractions at Universal CityWalk in Universal City,
California (opened in November 1993), the Trocadero Arcade in London (opened in
September 1994), and Osaka, Japan (opened in August 1995) (collectively, the
"O&O Theatres"). Generally, in each of these arrangements, the Company receives
reimbursement for direct expenses, a percentage of each theatre's cash flow
(equal to its ownership percentage), and receives separately annual film
licensing revenues and management fees (if applicable). The Company accounts for
its investment in the O&O Theatres under the equity method of accounting. The
Company has ceased operation of the theatres in Framingham, Massachusetts
(closed in October 1997) and in San Antonio, Texas (closed in September 1997)
and has either sold or is negotiating to sell to non-affiliated third parties
the equipment from each such theatre. The investment in each such closed theatre
is now reflected in equipment sales inventory. The Company expects to fully
realize the aggregate carrying value of the equipment retained by the Company
upon completion of such sales.

        The Company had accepted on behalf of its joint venture (the "UA
Venture") with United Artists Theatre Circuit, Inc. ("UA") the offer of the
Showscan Attraction site in Austin, Texas, which acceptance was to be effective
July 1, 1997. During the process of finalizing documentation relating to the
acquisition of the Austin site, however, UA entered into a merger agreement with
two other large theatre chains, and the circumstances surrounding the merger
transaction created uncertainty with respect to the Austin site. Accordingly,
the UA Venture has terminated its plans to acquire ownership of the Showscan
Attraction at the Austin site. In addition, the Company was to acquire a 15%
investment in a Showscan Attraction in Darling Harbour, Sydney, Australia.
During the process of finalizing documentation relating to such investment,
however, disputes arose regarding (i) the valuation of costs associated with the
Showscan Attraction, which costs were used to calculate the price of the 15%
investment and (ii) the remaining payment obligations owed to the Company by
Reality Cinema Pty. Ltd., the co-investor which was to own an 85% interest in
the Showscan Attraction. Accordingly, the Company has advised Reality Cinema
Pty. Ltd. that the Company will not proceed with its plans to acquire any
ownership of a Showscan Attraction at the Sydney site until such disputes are
satisfactorily resolved.

Note 4--11% Promissory Note

        On November 1, 1997, the Company completed a placement of a $1,000,000
promissory note through an unaffiliated third party. The note bears interest at
a rate of 11 percent per annum. The principal and interest amounts are due and
payable in full on November 15, 1998 or, if earlier, the date which is six
months after the close of a merger involving the Company. The note is secured by
accounts receivable from the distribution of the Company's film library and the
proceeds thereof.

Note 5--8% Convertible Notes:

        On September 1, 1995, the Company completed a private placement of
$7,000,000 in secured convertible notes (8% Convertible Notes") through a
European financial institution, Banca del Gottardo. The notes have a four-year
maturity and an 8% interest rate payable semi-annually and are convertible at
the option of the holder into 1,217,391 shares of the Common Stock at a



                                       9
<PAGE>   10
conversion price of $5.75 per share. Through December 31, 1997, $1,310,000 of
such notes had been converted into 227,819 shares of Common Stock leaving an
outstanding balance of $5,690,000. The notes are secured by substantially all of
the assets of the Company, although the security excludes the Company's film
library and the capital stock of its subsidiaries (which thereby excludes its
O&O Theatres). In connection with the placement, $619,000 of debt issue costs
were incurred and are being amortized over the life of the notes.

Note 6--Loss per common share:

        Loss per common share for the three months ended December 31, 1997 and
December 31, 1996 has been determined by using 5,642,058 and 5,631,605 weighted
average shares of Common Stock, respectively. For the nine months ended December
31, 1997 and December 31, 1996, the weighted average shares of Common Stock used
to determine loss per common share were 5,642,058 and 5,578,597, respectively.
The impact of common stock equivalents and potentially dilutive securities, such
as the assumed conversion of Series C Convertible Preferred Stock and the
assumed conversion of the 8% Convertible Notes due September 1, 1999 has not
been included, as such items are anti-dilutive for all periods presented.

        The Company has adopted Financial Accounting Standards Board Statement
of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS No.
128"). SFAS No. 128 establishes standards for computing and presenting earnings
per share ("EPS") and supersedes APB Opinion No. 15, "Earnings Per Share" ("APB
No. 15"). SFAS No. 128 replaces the presentation of primary EPS with a
presentation of basic EPS. Basic EPS excludes the dilutive effects, if any, of
common stock equivalents, and is computed by dividing income available to common
stockholders by the weighted average number of common shares outstanding during
the period. SFAS No. 128 also requires dual presentation of basic EPS and
diluted EPS on the face of the income statement for all periods presented.
Diluted EPS is computed similarly to fully diluted EPS pursuant to APB No. 15,
with certain modifications.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS 
OF OPERATIONS

Overview:

        Showscan Entertainment Inc. (the " Company") is a leading provider of
movie-based motion simulation theatre attractions ("Showscan Attractions") to
the rapidly expanding out-of-home entertainment market. The Company's business
includes: (i) licensing and distributing the films in its library and the
proprietary technologies necessary to produce and exhibit Showscan films; (ii)
selling and installing Showscan Attractions and specialty theatres including the
equipment necessary for each (including motion bases, projectors, screens, sound
systems, synchronization and show control, and theatre design packages); (iii)
producing films using the Showscan process; and (iv) establishing Showscan
Attractions in which the Company has an economic interest ("O&O Theatres"). The
Company is also committed to the continued recognition of the Showscan(R) brand
name worldwide.

        The principal sources of the Company's revenues are the licensing of the
Showscan film library and technologies, the sale and installation of projectors,
screens, sound systems and other equipment used to exhibit Showscan films, and
the sale of motion bases and other equipment used in most Showscan Attractions.
The Company currently derives most of its revenues from export sales. However,
the Company plans to increase its domestic sales through its agreement with
United Artists Theatre Circuit, Inc. The agreement calls for 24 sites, eight of
which are currently installed and the remaining 16 of which are in the Company's
backlog. The Company does not believe that inflation has had a material impact
on the Company's net revenues or on its results of operations for the three most
recent fiscal years.

        On August 4, 1997, the Company entered into an agreement (the "Merger
Agreement") with Iwerks Entertainment, Inc. ("Iwerks") pursuant to which a
subsidiary of Iwerks will be merged (the "Merger") with and into the Company.
This agreement was amended on December 29, 1997 to reduce the consideration
being offered. Under the terms of the amended Merger Agreement, each share of
the Company's common stock, $.001 par value (the "Common Stock"), which is
outstanding immediately prior to the Merger shall be converted into .62 shares
of Iwerks' common stock, $.001 par value. As a result of the Merger, the Company
will become a wholly-owned subsidiary of Iwerks and the shares of Common Stock
will cease to be publicly traded. Consummation of the Merger is subject to
certain conditions, including certain approvals by the stockholders of both the
Company and Iwerks. The Company currently anticipates holding a stockholder
meeting (and that the Merger will close) in March, 1998. On February 3, 1998,
Ridefilm Corporation, a wholly-owned subsidiary of Imax Corporation, filed suit
against Iwerks in the United States District Court for the Southern District of
New York. This lawsuit, among other things, seeks to enjoin the Merger under
various antitrust claims. Ridefilm is seeking a preliminary injunction of the
Merger as well. The Company and Iwerks are vigorously defending these claims and
are opposing the request for preliminary injunction.

Comparison of the nine months ended December 31, 1997 and 1996:

        Revenues for the nine-month period ended December 31, 1997 (the "Nine
Month Period") decreased by $5.8 million or 45% from revenues for the nine-month
period ended December 31, 1996 due to a substantial decrease in revenues
recognized from equipment sales and related services.

        Revenues from equipment sales and related services for the Nine Month
Period decreased 59% to $4.2 million from $10.2 million in the nine-month period
ended December 31, 1996. The decrease is due to the decrease in the number of
Showscan Attractions shipped during the Nine Month Period as compared to the
corresponding prior year nine-month period. Only five Showscan Attractions were
shipped (two of which were relocations of existing Showscan Attractions) in the
Nine Month Period as compared to the fourteen units shipped in the nine-month
period ended December 31, 1996. This decrease can be attributed to the
significant slow down in new sales orders since the announcement of the Merger
on August 5, 1997. The decrease in revenues was further complicated by the delay
in timing of certain projects in the Asian market. The Company believes this
delay is primarily due to the economic crisis currently being experienced in
Asia and that the adverse impact on revenues will continue in future periods.

        Film licensing and production service revenues increased by 6% to $2.9
million in the Nine Month Period due to the increase in the number of operating
Showscan Attractions and the addition of production service revenues from one
film that were not present in the year earlier period.

        The Company recognizes equipment sales under the
percentage-of-completion method of accounting, generally measured by the
percentage that the labor hours incurred to date bears to the estimated total
labor hours of each contract. This results in a disparity in the comparison of
equipment sales revenues over different time periods, as the Company records
revenues under this method rather than on the date that the sales agreement is
signed. The actual signing of a Showscan Attraction sale precedes its delivery
and installation by an average of five to six months. Accordingly, the
recognition of revenue for equipment sales during the current and future
quarters is affected by (i) the timing of such sales; (ii) the schedule of the
build-out of the Showscan Attractions; and (iii) the shipment, delivery and
installation of the equipment and related services.

        The Company presently has four Showscan Attractions in various stages of
manufacturing, delivery and installation, and an additional four Showscan
Attractions pending installation.

        Costs of revenues were 84% of revenues in the Nine Month Period as
compared to 70% in the nine-month period ended December 31, 1996. Equipment cost
of sales to total equipment sales increased to 81% in the Nine Month Period from
77% in the nine-month period ended December 31, 1996. Film licensing cost of
sales to total film licensing sales was 88% in the Nine Month Period as compared
to 45% in the nine-month period ended December 31, 1996. The increase in film
licensing cost of sales is due to the increase in film amortization in the Nine
Month Period from the nine-month period ended December 31, 1996.

        Amortization of the film library for the Nine Month Period and the
nine-month period ended December 31, 1996 was $1,833,000 and $458,000,
respectively. The increase in film amortization is due to a provision of
$1,150,000 to adjust the carrying value of two films at their estimated
realizable value and the additional amortization from new films in the Nine
Month Period that were 



                                       12
<PAGE>   13
in the production process in the nine-month period ended December 31, 1996. The
Company reviews film library estimated revenues on a quarterly basis (based on
the then current market conditions) and, where applicable, unamortized film
costs are written down to estimated net realizable value.

        General and Administrative expenses increased 9% in the Nine Month
Period, as the Company incurred expenses related to the Merger and recorded a
$500,000 increase in the allowance for doubtful accounts to reflect conditions
in the general Asian market, offset by a reduction in the Company's overhead
expenses.

        The loss on investment in O&O Theatres increased to $468,000 in the Nine
Month Period from $445,000 in the nine-month period ended December 31, 1996. The
loss for the Nine Month Period is primarily the result of the following factors:
(i) operating losses at the Framingham, Trocadero, San Antonio Riverwalk and
Universal CityWalk theatres, (ii) offset by the operating profits of the Osaka
theatre. The Company earns film licensing revenues (from all O&O Theatres) and
management fees (from some of the O&O Theatres) which are recorded separately in
the accompanying consolidated statements of operations, thereby inherently
increasing the operating expenses at the specific O&O Theatres. A formal claim
that was filed with the owner of the Trocadero building to recover damages
resulting from the renovation of the Trocadero building and the related access
problems has been settled, wherein the Showscan subsidiary which owns the
theatres was reimbursed in the Nine Month Period for a portion of its damages
incurred during the renovation period. The Company has ceased operations at the
Framingham (closed in October 1997) and San Antonio (closed in September 1997)
theatres and has either sold or is negotiating to sell to non-affiliated third
parties the equipment from each theatre location. The joint venture partners of
each respective theatre have agreed to these sales. The Company expects to fully
realize the aggregate carrying value of its investment in both joint ventures
upon completion of such sales and the subsequent liquidation of the related
joint ventures.

        The Company's net loss increased in the Nine Month Period to $5,875,000
from $2,596,000 in the nine-month period ended December 31, 1996, due to (i) the
decrease in equipment sales revenues, (ii) the performance of the O&O Theatres,
(iii) the provision of $1,150,000 to adjust the carrying value of certain films
to their estimated realizable value, and (iv) the increase in general and
administrative expenses caused by expenses related to the proposed Merger and
the $500,000 increase in the allowance for doubtful accounts, as discussed
above. The Company does not believe that these results necessarily represent a
recurring trend.

Comparison of the three months ended December 31, 1997 and 1996:

        Revenues for the three-month period ended December 31, 1997 (the "1998
Third Quarter") decreased $795,000 or 19% from revenues for the three-month
period ended December 31, 1996 (the "1997 Third Quarter") due to a decrease in
revenues recognized from equipment sales and related services in the 1998 Third
Quarter.

        Revenues from equipment sales and related services for the 1998 Third
Quarter decreased 26% to $2.6 million from $3.5 million in the 1997 Third
Quarter. Three Showscan Attractions were shipped (two of which were relocations
of existing Showscan Attractions) in the 1998 Third Quarter as compared to the
five units shipped in the 1997 Third Quarter. This decrease can be attributed to



                                       13
<PAGE>   14
the significant slow down in new sales orders since the announcement of the
Merger on August 5, 1997. The decrease in revenues was further complicated by
the delay in timing of certain projects in the Asian market. The Company
believes this delay is primarily due to the economic crisis currently being
experienced in Asia and that the adverse impact on revenues will continue into
future periods.

        Film licensing and production service revenues increased 17% when
comparing the 1998 Third Quarter to the 1997 Third Quarter due to the increase
in the number of operating Showscan Attractions and the addition of production
service revenues from one film that were not present in the year earlier period.

        The Company recognizes equipment sales under the
percentage-of-completion method of accounting, generally measured by the
percentage that the labor hours incurred to date bears to the estimated total
labor hours of each contract. This results in a disparity in the comparison of
equipment sales revenues over different time periods, as the Company records
revenues under this method rather than on the date that the sales agreement is
signed. The actual signing of a Showscan Attraction sale precedes its delivery
and installation by an average of five to six months. Accordingly, the
recognition of revenue for equipment sales during the current and future
quarters is affected by (i) the timing of such sales; (ii) the schedule of the
build-out of the Showscan Attractions; and (iii) the shipment, delivery and
installation of the equipment and related services.

        The Company presently has four Showscan Attractions in various stages of
manufacturing, delivery and installation and an additional four Showscan
Attractions pending installation.

        Costs of revenues were 114% of revenues in the 1998 Third Quarter as
compared to 76% in the 1997 Third Quarter. Equipment cost of sales to total
equipment sales increased to 87% in the 1998 Third Quarter from 74% in the 1997
Third Quarter. The increase was principally the result of the recognition of two
relocations of existing Showscan Attractions that provided lower profit margins
in the 1998 Third Quarter when compared to equipment sales in the 1997 Third
Quarter. These relocations, though they lower profit margins on sales, are
beneficial to the Company in that they provide continued operations and film
rental from the theatres rather than closures. Film licensing cost of sales to
total film licensing sales was 202% in the 1998 Third Quarter as compared to 84%
in the 1997 Third Quarter. The increase in film licensing cost of sales is due
to the increase in film amortization in the 1998 Third Quarter from the 1997
Third Quarter.

        Amortization of the film library for the 1998 Third Quarter and the 1997
Third Quarter was $1,585,000 and $266,000, respectively. The increase in film
amortization is due to a provision of $1,150,000 to adjust the carrying value of
two films to their estimated realizable value and the additional amortization
from new films in the 1998 Third Quarter that were in the production process in
the 1997 Third Quarter. The Company reviews film library estimated revenues on a
quarterly basis (based on the then current market conditions) and, where
applicable, unamortized film costs are written down to estimated net realizable
value.

        General and Administrative expenses increased 51% in the 1998 Third
Quarter, as the Company incurred expenses related to the Merger and recorded a
$500,000 increase in the allowance for doubtful accounts to reflect conditions
in the general Asian market, offset by a reduction in the Company's overhead
expenses.



                                       14
<PAGE>   15
        The loss on investment in O&O Theatres in the 1998 Third Quarter
decreased 63% to $104,000 from the 1997 Third Quarter and was primarily the
result of the following factors: (i) operating losses at the Trocadero and
Universal CityWalk theatres, (ii) offset by the operating profits of the Osaka
theatre. The Company earns film licensing revenues (from all O&O Theatres) and
management fees (from some of the O&O Theatres) which are recorded separately in
the accompanying consolidated statements of operations, thereby inherently
increasing the operating expenses at the specific O&O Theatres.

        The Company's net loss increased in the 1998 Third Quarter to $3,264,000
from $1,182,000 in the 1997 Third Quarter, due to (i) the decrease in equipment
sales revenues, (ii) the performance of the O&O Theatres, (iii) the increase in
general and administrative expenses caused by expenses related to the proposed
Merger and the $500,000 increase in the allowance for doubtful accounts (as
discussed above), and (iv) the increase in film amortization including the
provision of $1,150,000 to adjust the carrying value of certain films to their
estimated realizable value. The Company does not believe that these results
necessarily represent a recurring trend.

Liquidity and Capital Resources:

        At December 31, 1997, the Company's working capital decreased to
$2,841,000 from $4,528,000 at March 31, 1997. The decrease in working capital
was primarily due to the increase in deferred revenues (net of the associated
unbilled receivables) on uncompleted equipment contracts, the addition of films
to the film library and the operating loss of the Company offset by the increase
in equipment sales inventory (from two of the three closed O&O Theatres which
are being held for sale).

        Cash and cash equivalents at December 31, 1997 decreased by $374,000
from March 31, 1997, which was the result of $1,208,000 used in operating
activities, $166,000 used in investing activities, and $1,000,000 provided by
financing activities.

        Net cash used in operating activities was primarily due to (i) the 30%
increase in accounts receivable, unbilled receivables and equipment sales
inventory, and (ii) a 49% decrease in accounts payable. The changes are
primarily attributable to variations in the timing of Showscan Attractions sales
and the specific contract terms of such sales, which terms generally affect the
timing of collections, shipments, deliveries to customers, installations and the
related payments to vendors.

        Net cash used in investing activities was primarily due to (i)
expenditures for the production and acquisition of fourteen motion simulation
films, partially offset by (ii) a decrease in other assets.

        Net cash provided by financing activities was due to a $1,000,000
($900,000 net of expenses) promissory note from a private institution on
November 1, 1997. The note has a one year maturity and bears interest at 11
percent per annum, with principal and interest due and payable in full on
November 15, 1998, or if earlier, the date which is six months after the close
of a merger involving the Company. The note is secured by accounts receivable
from the distribution of the Company's film library and the proceeds thereof.

        As Showscan derives 60-70% of its business from export sales, its
liquidity may be adversely affected by changes in worldwide economic or
political conditions. Such factors as changes in 



                                       15
<PAGE>   16
foreign currency exchange rates (which can significantly affect the
affordability of Showscan's products and services), trade protection measures,
and policies with respect to currency and fiscal controls may negatively affect
liquidity. The current Asian economic crisis has already caused the delay of
certain projects and the Company believes that it will have an adverse impact on
revenues in future periods.

        The Company's business strategy includes a significant increase in the
installed base of Showscan Attractions, new film productions, the securing of
distribution rights to motion simulation films produced by other companies, new
product development and new product lines, enhancement of existing product
lines, possible investments in O&O Theatres and the reduction of overhead by
30%. The Company has already achieved much of the overhead reduction. The
Company recently obtained certain distribution rights through May 1, 2002 to two
films produced by another company. On December 10, 1997 the Company announced
the acquisition of certain distribution rights to another eleven films produced
by another company.

         If the Merger with Iwerks should not occur, the Company intends to
finance the foregoing business strategy by utilizing its current working capital
resources, the proceeds to be received from its existing backlog and anticipated
future product sales and film licensing agreements, together with proceeds
derived from one or more of the following financing alternatives: the sale of
securities, the obtaining of a line of credit from a banking or another type of
institution, and/or the formation of strategic alliances, joint ventures or
off-balance sheet financing. There can be no assurance that the Company will be
able to obtain any of the aforementioned financing alternatives. If the Merger
with Iwerks should not occur and if the Company is unable to generate sufficient
funds from operations or is unable to raise additional capital through any of
the aforementioned alternatives, the Company will need to curtail its business
strategy, specifically with regard to new film productions and investments in
O&O Theatres, and its overhead expense. The Company believes that, given its
various business alternatives, its working capital will be sufficient to fund
the cost of its operations for the next twelve months though the $1 million loan
due in November 1998 would have to be refinanced. At February 1, 1998, the
Company has reserved 4,573,573 shares of Common Stock for issuance on the
exercise of stock options, warrants, preferred stock and convertible notes.

        Management of the Company has reviewed the provisions of SFAS 130 and
131 and determined that the ultimate adoption of these accounting standards will
not have an impact on the Company's financial statements and related
disclosures.

Impact of the Year 2000:

        Some of the Company's older computer software systems were written using
two digits rather than four to define the applicable year. As a result, those
computer programs have time-sensitive software that recognize a date using "00"
as the year 1900 rather than the year 2000. This software could cause a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices, or
engage in similar normal business activities.

        The Company has completed an assessment of its existing software systems
and after reviewing various factors, one of which being the year 2000 issue, has
determined which systems 



                                       16
<PAGE>   17
would need to be replaced or upgraded if the Merger with Iwerks did not occur.
The necessary upgrades would cost approximately $25,000.

        If necessary, these upgrades would be completed not later than June 30,
1999, which is prior to any anticipated impact on the operating systems. The
Company believes that with conversions to new software, the year 2000 issue will
not pose significant operational problems for its computer systems.

        The costs of the project and the date on which the Company believes it
will complete the conversion are based on management's best estimates, which
were derived utilizing numerous assumptions of future events, including the
continued availability of certain resources and other factors. However, there
can be no guarantee that these estimates will be achieved and actual results
could differ materially from those anticipated.

FACTORS THAT MAY AFFECT FUTURE RESULTS

        Portions of this report on Form 10-Q (this "Report") may contain
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. The reader is cautioned that all forward-looking
statements are necessarily speculative and there are certain risks and
uncertainties that could cause actual events or results to differ materially
from those referred to in such forward-looking statements. The discussion below,
together with portions of the discussion elsewhere in this Report and in the
Company's other reports on file with the Securities and Exchange Commission,
highlight some of the more important risks identified by the management of the
Company but should not be assumed to be the only things that could affect future
performance.

Period to Period Fluctuations

        The Company's operating results may fluctuate from period to period for
a number of reasons, including (i) the timing of sales of the Company's Showscan
Attractions, (ii) the timing of delivery and installation of such sales
(pursuant to percentage of completion accounting) and any delays therein caused
by permitting or construction delays at the customer's site, (iii) the size,
type and configuration of the attractions sold, (iv) the timing of film rental
payments from existing attractions and the performance of those attractions that
pay film rental based on a percentage of box office, and (v) the timing of sales
and marketing efforts and related expenditures. Accordingly, the Company's
revenues and earnings in any particular period may not be indicative of the
results for any future period. The seasonal fluctuations also cause gyrations in
the Company's stock price.

        The Company's performance depends primarily upon the number of Showscan
Attractions that it can sell and install. This dependence has been lessening as
the percentage of the Company's revenues derived from recurring film licensing
revenues has increased though there can be no assurance that this trend will
necessarily continue. The Company's results have followed a seasonal pattern,
with revenues tending to be stronger in the second half of the fiscal year,
reflecting the buying patterns of the Company's customers for new Showscan
Attractions.



                                       17
<PAGE>   18
Business Strategy

        Management of the Company has adopted a business strategy that includes
substantial investments in the installed base of Showscan Attractions, new film
productions, the securing of distribution rights to motion simulation films
produced by other companies, new product development and new product lines,
enhancement of existing product lines, possible investments in O&O Theatres and
the reduction of overhead. This strategy carries with it a number of risks,
including reaching a level of operating expenses that may not be adequately
covered by increased sales, film licensing revenues or by additional financing
(due to unfavorable terms). This strategy will have to be curtailed if adequate
funds are not available.

New Product Development

        The Company operates in a technology driven segment of the entertainment
business. As such, the Company must continually improve its products to increase
their entertainment value while also facing pressure to continually reduce the
price of its products to respond to competitive pressures. Since the Company's
main competitors, Iwerks (until the Merger is completed) and Imax Corporation
("Imax"), have significantly more capital than the Company, the Company has had
to rely more on its suppliers and other third parties to improve the Company's
existing products and to develop new ones. The inability of the Company to
develop new products and to respond to technological developments of its
competitors could have a materially adverse effect on the Company's business,
operations and financial condition.

International Operations

        A significant portion of the Company's sales and film licensing are made
to customers located outside of the United States, primarily in the Far East and
Europe. During fiscal 1995, 1996 and 1997, 69%, 61% and 62% of the Company's
revenues, respectively, were derived from sales outside the United States.
During fiscal 1997, the Japanese market was the only foreign market with over
10% of the Company's revenues, with a share of 17.6%. International operations
and sales of the Company may be subject to political and economic risks,
including political instability, currency controls, exchange rate fluctuations
(which, in the event of a decrease in value of foreign currency to the dollar,
can significantly affect the affordability of the Company's products overseas
such as is currently occurring in many Asian countries), changes in
import/export regulations, tariff and freight rates, longer accounts receivable
collection patterns, changes in regional or worldwide economic or political
conditions and natural disasters. In addition, various forms of protectionist
trade legislation have been proposed in the United States and certain other
countries. Any resulting changes in current tariff structures or other trade and
monetary policies could adversely affect the Company's international operations.
Political and economic factors have been identified by the Company with respect
to Asia and certain other markets in which it competes. Regions such as Asia
have recently experienced economic problems and these problems are expected to
continue through 1998. This economic crisis was a contributing factor to the
delay in the timing of certain of the Company's projects in the past nine months
and will likely have an impact on new sales and film license renewals in future
periods. There can be no assurance that these factors will not result in
customers of the Company defaulting on payments due to it, or in the reduction
of potential purchases of its products. The Company has not engaged in any
currency hedging programs.



                                       18
<PAGE>   19
Intellectual Property

        The Company has several United States patents on various processes and
elements related to film projection and motion simulation. The most important of
these patents expire in October 2001. Though the Company's patents have never
been challenged and the Company believes that they are valid, third parties
could still challenge the patents and a court could determine that one or more
of them are invalid. Declarations of invalidity, particularly of the Company's
key patents, could adversely affect the marketability of the Company's products
and services. In addition, the Company always faces the risk that new
technologies could be discovered that are superior to the Company's patents.

Intense Competition; Unpredictability of Consumer Tastes

        Competition in each of the markets in which the Company competes is
intense. The principal direct competition for customers comes from manufacturers
of competing movie-based attractions, and in the case of amusement and theme
parks, manufacturers of traditional amusement park attractions. In addition to
direct competitors, there is also competition from systems integrators and some
amusement and theme parks developing and constructing their own attractions.
Many of the Company's competitors have better name recognition, and
substantially greater financial and other resources than the Company.

        In the motion simulation business, the Company's main competitor (until
the Merger is completed) is Iwerks. Imax and a number of smaller competitors are
growing competitors of the Company in the ride simulation business and have
dedicated substantial resources to entering into this market.

        In the large screen, special format motion picture business, the
Company's main competitor is Imax though Iwerks is also very significant. The 15
perforation 70 millimeter film format appears to be emerging as the most popular
large format due primarily to the large number of films available in that
format. Imax is by far the dominant company in this market.

        Additionally, the out-of-home entertainment industry in general is
undergoing significant changes, primarily due to technological developments as
well as changing consumer tastes. Numerous companies are developing and are
expected to develop new entertainment products or concepts for the out-of-home
entertainment industry in response to these developments that are or may be
directly competitive with existing products. There is severe competition for
financial, creative and technological resources in the industry and there can be
no assurance that existing products will continue to compete effectively or that
products under development will ever be competitive. Further, the commercial
success of products is ultimately dependent upon audience reaction. Audience
reaction will to a large extent be influenced by the audience's perception of
how the Company's products compare with other available entertainment options
out of the home. There can be no assurance that new developments in out-of-home
entertainment will not result in changes in consumer tastes that will make the
Company's products less competitive.



                                       19
<PAGE>   20
Business Disruption

        The Company's corporate headquarters, including its research and
development operations, are located in Los Angeles, California, a region known
for seismic activity. Operating results could be materially affected by a
significant earthquake or other natural disaster.

Dependence on Major Customers

        The Company's motion simulation business has two significant
concentrations. The first concentration involves ongoing film licenses and is
located in Japan where a single customer, Imagine Japan, presently operates or
is otherwise responsible for fifteen Showscan Attractions. The second
concentration relates to the Company's sales backlog where United Artists
Theatre Circuit, Inc. and King's Entertainment Co., Ltd., individually and
collectively, represent a substantial portion of the outstanding equipment
orders to be delivered in the next few years. The Company's agreement with
United Artists Theatre Circuit, Inc. calls for a build out period extending
through August 1999 while that with King's Entertainment Co., Ltd. extends
through May 2002. Each site opened under each agreement shall have an initial
film license period of at least three years. In the fiscal year ended March 31,
1997, the Company earned revenues from Imagine Japan and United Artists Theatre
Circuit, Inc. in the amounts of $3,117,000 and $5,405,000, respectively. The
Company's short and long term performance could be adversely impacted if
disruptions were to occur in any of these areas of concentration such as order
cancellations, license terminations or payment problems.

Ability to Produce Additional Films

        One of the primary factors considered by potential purchasers of motion
simulation attractions is the quality and extent of the films available to be
shown at the attraction. The Company believes that a large portion of its
competitive advantage resides in its popular and extensive library of ride
films. To maintain this competitive edge, the Company must produce or acquire
the distribution rights to several new films each year. Film production is
expensive and requires the investment of Company funds (to the extent that
investors cannot be located) with no assurance that the films produced will be
popular. Iwerks and Imax have each indicated that they are devoting substantial
portions of their assets to the production of new motion simulation films. Both
the short and long term financial performance of the Company will be adversely
affected if the perceived quality and popularity of the Company's film library
declines either alone or in comparison to the films of the Company's
competitors.

Volatility of Stock Price

        The Company's stock price has been, and could continue to be, highly
volatile. The market price of the Company's Common Stock has fluctuated
substantially in recent periods. During the 12 months prior to December 31,
1997, the Company's market price has ranged from a low of $1 per share to a high
of $5 3/8 per share. Any future announcements concerning the Company or its
competitors, quarterly variations in operating results, introductions of new
products or changes in product pricing policies by the Company or its
competitors or the acquisition or loss of significant customers that affect or
are perceived to affect the Company's operations, could cause the market price
of the Common Stock to fluctuate substantially. In addition, stock markets have
experienced 



                                       20
<PAGE>   21
extreme price and volume volatility in recent years. This volatility has had a
substantial effect on the market prices of securities of many smaller companies
for reasons frequently unrelated to the operating performance of the specific
companies. These broad market fluctuations may adversely affect the market price
of the Common Stock.

Environmental Matters and Other Governmental Regulations

        Under various Federal, state and local environmental laws and
regulations, a current or previous owner or occupant of real property may become
liable for the costs of removal or remediation of hazardous substances at such
real property. Such laws and regulations often impose liability without regard
to fault. The Company leases its corporate headquarters and the Company could be
held liable for the costs of remedial actions with respect to hazardous
substances on such property under the terms of the governing lease and/or
governing law. Although the Company has not been notified of, nor is otherwise
aware of, any current environmental liability, claim or non-compliance, there
can be no assurance that the Company will not be required to incur remediation
or other costs in the future in connection with the leased property. In
addition, the Company's subcontractors and other third parties, with which it
has contractual relations, are similarly subject to such laws. The Company
believes it is in compliance with all applicable Federal, state and local
environmental laws and regulations.
