                        SPATIALIGHT, INC. AND SUBSIDIARY
              Notes to Condensed Consolidated Financial Statements

1.     Business Description

SpatiaLight, Inc. and its subsidiary ("SpatiaLight" or the "Company") are in the
business of designing and commercializing miniature, high-resolution active
matrix liquid crystal displays mounted directly on silicon chips. These displays
are also known as and commonly referred to as Liquid Crystal Displays ("LCD"),
Active Matrix Liquid Crystal Displays ("AMLCD"), Liquid Crystal on Silicon
("LCOS"), and Spatial Light Modulators ("SLM"). These displays are designed in a
manner that can potentially provide high-resolution images suitable for
computer, video and other applications while utilizing the existing
manufacturing processes of typical silicon and liquid crystal displays to obtain
economies of scale and thereby reduce costs. To date, the Company has only sold
small quantities of its displays to customers who are evaluating the displays
for use in their products.

The Company has identified a number of potential applications and markets for
products, which can utilize its display technology. Some of these applications
include: large-screen rear-projection television systems, in both standard
television format ("NTSC") and future High Definition Television ("HDTV")
formats; large-screen rear-projection computer monitors in a variety of
resolutions; video projectors for presentations; head-mounted displays which are
used for virtual reality systems, defense, aerospace and gaming applications;
and other potential applications such as point of purchase displays, optical
computing, data storage and holographic imaging systems.

The address and telephone number of the Company's principal executive offices
are 9 Commercial Boulevard, Suite 200, Novato, California 94949, (415) 883-1693.
The Company was organized under the laws of the State of New York in 1989 under
the name of "Sayett Acquisition Company, Inc."; it subsequently changed is name
to Sayett Group and in June 1996 changed its name to SpatiaLight, Inc. The
Company has a wholly owned subsidiary named SpatiaLight of California, Inc.

2.     Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-QSB of item 310(b) of
Regulation S-B. Accordingly they do not include all of the information and
footnotes necessary for a fair presentation of financial condition, results of
operations and cash flows in conformity with generally accepted accounting
principles. In the opinion of management of SpatiaLight, the interim condensed
consolidated financial statements included herewith contain all adjustments
(consisting of normal recurring accruals and adjustments) necessary for their
fair presentation. The unaudited interim condensed consolidated financial
statements should be read in conjunction with the Company's 1999 Annual Report
on Form 10-KSB, which contains the audited financial statements and notes
thereto, together with the Management's Discussion and Analysis, for the years
ended December 31, 1999 and 1998.

3.     Per Share Information

Basic loss per common share available to common shareholders excludes dilution
and is computed by dividing loss available to common shareholders by the
weighted-average number of common shares for the period. Due to the net loss
reported for the three and nine months ended September 30, 2000, stock options
and warrants have been excluded from the diluted EPS calculation. Securities
that could potentially dilute basic EPS in the future and were not included in
the calculation of dilutive EPS because to do so would have been antidilutive
for the periods presented are options and warrants to acquire 5,922,312 and
6,692,315 shares of common stock for September 30, 2000 and 1999 respectively,
and 2,786,714 and 5,251,000 common share equivalents relating to convertible
secured notes, from the assumed exercise of such instruments. The weighted
average price as of September 30, 2000 for the options, warrants and common
share equivalents is $2.34, $3.06 and $0.94, respectively.

4.     Convertible Notes

Convertible notes at September 30, 2000 relate to notes from Argyle Capital
Management Corporation, a company affiliated with Robert Olins, a Director and
Acting Chief Executive Officer of the Company. The notes accrue interest at a
face rate of 6% and are due on June 30, 2001. The notes plus all accrued
interest at the time of conversion are convertible into the Company's common
stock at $.50 per share. The notes are secured by substantially all the assets
of the Company. The Company has assumed that the interest accrued, at a rate of
6%, from July 1 to September 30, 2000 will be converted into 36,432 shares of
common stock since the Company's stock price was greater than $.50 per share
throughout this period. Using the average stock price of $2.65 for the
three-month period to value such shares, the Company has accrued stock-based
interest expense of $96,545 for the three months ended September 30, 2000. The
Company has accrued stock-based interest expense of $603,449 for the nine months
ended September 30, 2000.

Long-term convertible notes totaling $2,875,000 were issued in December 1999.
These convertible notes bear an interest rate of 6%, are convertible into common
stock at $3.50 per share, and are due on June 30, 2001. As of December 31, 1999
the Company received the first installment of $1,437,500. The second installment
of $1,437,500 will be received upon achievement of a performance target. No
conversions have taken place as of September 30, 2000. A value of $1,437,500 was
assigned to warrants issued in conjunction with the convertible notes and was
recorded as a discount on the convertible notes. This amount is being recognized
as interest expense over the term of the note at an annual rate of approximately
1,230%. Interest expense related to this discount was insignificant in 1999, and
is expected to be $3,615 in 2000 and $1,433,885 in 2001, unless the debt is
converted into equity at an earlier date.

5.     Issuance of Securities

During the third quarter of 2000 the Company issued 29,500 and 2,300 shares of
common stock upon the exercise of options and warrants, respectively. Total cash
received was $11,125.

During the third quarter the Company entered into an employment agreement under
the terms of which the employee was granted options to purchase up to 1,975,000
of the Company's common stock at an exercise price of $4.80 per share subject to
meeting certain performance criteria prior to June 30, 2002. The shares will be
issued outside of the 1999 Employee Stock Option Plan and are subject to
approval by the shareholders of the Company.

During the third quarter of 2000, the Company issued an option to purchase
150,000 shares of common stock in exchange for consulting services to be
rendered over a 3-month period. The option has an exercise price of $4.00 A
value of $173,935 was assigned to the option, using the Black-Sholes option
pricing model and the following assumptions: volatility 100 %, risk-free
interest rate 6.25%, a dividend yield of 0, a contractual term of 3 years, and
the stock price of $2.1875 which was the fair value of the underlying common
stock. This option was recorded as stock-based general and administrative
expense.

6.     Segment Reporting

The Company's chief operating decision-maker, the Chief Executive Officer (CEO),
reviews the Company's financial information a basis substantially consistent
with the accompanying consolidated financial statements to make decisions about
the Company's performance and resource allocation. Therefore the Company has
determined that it



                                       7
<PAGE>   8

operates in a single business segment. The Company's revenue for 2000 and 1999
consisted of sales of prototypes and developer kits, respectively.

The Company sells to a small number of customers.

7.     Subsequent Events

In connection with the convertible notes described in Note 4, on November 7,
2000 Argyle Capital Management Corp. converted all of its accrued interest into
common shares of the Company. Accrued interest of $84,546 at September 30,
2000 was converted into 169,092 common shares.

8.     New Accounting Pronouncements

In March 2000, the Financial Accounting Standards Board issued Interpretation
No. 44 ("FIN 44"), "Accounting for Certain Transactions Involving Stock
Compensation (an interpretation of APB Opinion No. 25)". FIN 44 clarifies the
application of APB Opinion No. 25 for certain issues: (a) the definition of
employee for purposes of applying Opinion 25, (b) the criteria for determining
whether a plan qualifies as a noncompensatory plan, (c) the accounting
consequence of various modifications to the terms of a previously fixed stock
option or award, and (d) the accounting for an exchange of stock compensation
awards in a business combination. Generally, FIN 44 is effective July 1, 2000.
The adoption of FIN 44 did not have a material impact on the Company's
consolidated financial position or results of operations.

In December 1999, the Securities and Exchange Commission ("SEC") issued Staff
Accounting Bulletin No. 101("SAB 101"), "Revenue Recognition," which outlines
the basic criteria that must be met to recognize revenue and provides guidance
for presentation of revenue and for disclosure related to revenue recognition
policies in financial statements filed with the SEC. SAB 101 is effective the
fourth fiscal quarter of fiscal years beginning after December 15, 1999 as
amended by SAB 101B. The Company believes the adoption of SAB 101 will not have
a material impact on the Company's financial position and results of operations.

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 133 ("SFAS 133") "Accounting for
Derivative Instruments and Hedging Activities", as amended by SFAS 137
"Accounting for Derivative Instruments and Hedging Activities - Deferral of the
Effective Date of FASB Statement No. 133 - an Amendment of FASB Statement No.
133" and SFAS 138 "Accounting for Certain Derivative Instruments and Certain
Hedging Activities - an Amendment of FASB Statement No. 133"which establishes
accounting and reporting standards for derivative instruments and hedging
activities. The terms of SFAS 133 and SFAS 138 are effective as of the beginning
of the first quarter of the fiscal year beginning after June 15, 2000. The
Company is determining the effect of SFAS 133, 137 and 138 on its financial
statements.

and 1999. The following should be read in conjunction with the unaudited
consolidated financial statements and related notes appearing elsewhere herein.

OVERVIEW

SpatiaLight is developing and commercializing a miniature, high-resolution
active matrix liquid crystal display. Our display is designed to be a component
in high-resolution, projected display systems, which may be produced at lower
costs than current or anticipated projection systems. We have produced
developer kits, which have been made available to potential customers. Potential
applications of this technology include projection computer monitors and
televisions, head mounted displays, optical computing, holographic imaging and
other display applications. We have made only limited sales to date, and there
can be no assurance that we will ever be able to commercialize our technology.



                                       8
<PAGE>   9

LIQUIDITY AND CAPITAL RESOURCES

Most of our revenues to date have been derived from sales of our prototypes and
developer kits. Although we are producing displays in anticipation of mass
production, we have not yet completed our goal of mass production. Delays in
development may result in the introduction of products later than anticipated,
which may have an adverse effect on both our financial and competitive position.
Moreover, we may never be successful in developing or manufacturing a
commercially viable display and in addition, we may never be able to manufacture
adequate quantities of our displays at commercially acceptable cost levels or on
a timely basis.

As of September 30, 2000, we had approximately $1,119,000 in cash and cash
equivalents. This was, in large part, a result of the exercise of warrants by a
group of existing warrant holders during the first quarter of 2000 whereby we
received cash proceeds of approximately $4,000,000. Our current liabilities
exceed our current assets at September 30, 2000 by approximately $1,587,000.
On November 10, 2000, the Company issued 169,092 common shares in exchange for
$84,546 accrued interest on convertible notes.

Net cash used in operating activities totaled approximately $4,571,000 and
$2,290,000 for the nine months ended September 30, 2000 and 1999, respectively.
Cash was used primarily to fund the operating loss offset in part, by non-cash,
stock-based expenses.

Net cash provided by financing activities in the nine months ended September 30,
2000 was approximately $4,959,000 as compared to approximately $2,398,000 for
the nine months ended September 30, 1999. Cash was provided primarily from
proceeds from the exercise of warrants to purchase our common stock and the
exercise of options to acquire our common stock.

As of September 30, 2000, we had an accumulated deficit of approximately
$27,469,000. We have realized significant losses in the past and we expect that
these losses will continue through 2000 and 2001. It is likely that we will have
quarterly and annual losses in 2000 and beyond. We have generated limited
revenues and no profits from operations. The development, commercialization and
marketing of our products will require substantial expenditures for the
foreseeable future. Consequently, we may continue to operate at a loss for the
foreseeable future and there can be no assurance that our business will operate
on a profitable basis. We will have to raise additional capital within the next
12 months.

RESULTS OF OPERATIONS

Revenues. Total revenues were approximately $62,000 for the nine months ended
September 30, 2000, and $7,000 for the three months ended September 30, 2000.
Total revenues were $62,000 for the nine months ended September 30, 1999, and
$21,000 for the three months ended September 30, 1999. The revenues earned in
2000 were from the sales of our fifth generation developer kits.

Cost of Revenues. Cost of revenues represents product costs associated with the
production of display prototypes. Cost of revenues for prototypes was
approximately $16,000 and $1,300 for the nine months and three months ended
September 30, 2000, respectively and $11,000 and $5,500 for the nine months and
three months ended September 30, 1999, respectively. Gross margins associated
with sales are not indicative of the gross margins that we expect to realize on
sales of units produced in quantity. Prototypes and developer kits have a higher
unit price than mass-produced units due to the time and effort spent with
customers.

Selling, general and administrative costs. Selling, general and administrative
costs were approximately $1,983,000 and $613,000 in the nine months and three
months ended September 30, 2000, respectively and $1,458,000 and $570,000 in the
nine and three months ended September 30, 1999, respectively.



                                       9
<PAGE>   10
These increases were due primarily to the cost associated with the
implementation of our accounting system, and accounting and auditing fees.

Stock-based general and administrative costs. Stock-based general and
administrative costs were approximately $189,000 and $174,000 in the nine and
three months ended September 30, 2000, respectively, and approximately $862,000
and $327,000 in the nine and three months ended September 30 1999, respectively.
The amounts incurred relate to the valuation of common stock, stock options, and
options issued in exchange for services and other consideration. The amount
incurred in 2000 relates to stock and stock options issued in exchange for
services. The amount incurred in 1999 relates to consulting services rendered in
advising us as to feasible capital structures and identifying appropriate
capital sources.

Research and development costs. Research and development costs were
approximately $2,709,000 and $1,333,000 in the nine months ended September 30,
2000 and 1999, respectively. Research and development costs were approximately
$1,029,000 and $559,000 in the three months ended September 30, 2000 and 1999,
respectively. These increases were due primarily to an increase in salaries and
consulting and other costs associated with the design and implementation of a
new product.

Interest income. Interest income for the nine months ended September 30, 2000
and 1999 was approximately $80,000 and $8,000, respectively. Interest income for
the three months ended September 30, 2000 and 1999 was approximately $22,000 and
$0, respectively. The increase was due to higher cash balances resulting from
the exercise of warrants and options during the first two quarters of 2000.

Interest expense. Interest expense for the nine months ended September 30, 2000
and 1999 was approximately $125,000 and $161,000, respectively. Interest expense
for the three months ended September 30, 2000 and 1999 was approximately $25,000
and $51,000, respectively. The decrease resulted primarily from the conversion
of certain convertible notes into common shares of the Company in the second and
third quarters of 1999. In addition, capital lease obligations are nearing
termination resulting in lower interest expense in 2000.

Stock-based interest expense. Stock-based interest expense for the nine months
ended September 30, 2000 and 1999 was approximately $603,000 and $0,
respectively. Stock-based interest expense for the three months ended September
30, 2000 and 1999 was approximately $97,000 and $0, respectively. The amounts
incurred in 2000 relate to the assumption that the interest accrued on certain
convertible notes will be converted to equity based on the average fair market
value of the stock over the nine-month period. Amounts incurred in 1999 relate
to warrants issued in connection with a note extension.

NEW ACCOUNTING PRONOUNCEMENTS

In March 2000, the Financial Accounting Standards Board issued Interpretation
No. 44 ("FIN 44"), "Accounting for Certain Transactions Involving Stock
Compensation (an interpretation of APB Opinion No. 25)". FIN 44 clarifies the
application of APB Opinion No. 25 for certain issues: (a) the definition of
employee for purposes of applying Opinion 25, (b) the criteria for determining
whether a plan qualifies as a noncompensatory plan, (c) the accounting
consequence of various modifications to the terms of a previously fixed stock
option or award, and (d) the accounting for an exchange of stock compensation
awards in a business combination. Generally, FIN 44 is effective July 1, 2000.
The adoption of FIN 44 did not have a material impact on the Company's
consolidated financial position or results of operations.

In December 1999, the Securities and Exchange Commission ("SEC") issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition," which outlines
the basic criteria that must be met to recognize revenue and provides guidance
for presentation of revenue and for disclosure related to revenue recognition
policies in financial statements filed with the SEC. SAB 101 is effective the
fourth fiscal quarter of fiscal years beginning after December 15, 1999 as
amended by SAB 101B. The Company believes the adoption of SAB 101 will not have
a material impact on the Company's financial position and results of operations.

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 133 ("SFAS 133") "Accounting for
Derivative Instruments and Hedging Activities", as amended by SFAS 137
"Accounting for Derivative Instruments and Hedging Activities - Deferral of the
Effective Date of FASB Statement No. 133 - an Amendment of FASB Statement No.
133" and SFAS 138 "Accounting for Certain Derivative Instruments and Certain
Hedging Activities - an Amendment of FASB Statement No. 133" which establishes
accounting and reporting standards for derivative instruments and hedging
activities. The terms of SFAS 133 and SFAS 138 are effective as of the beginning
of the first quarter of the fiscal year beginning after June 15, 2000. The
Company is determining the effect of SFAS 133, 137 and 138 on its financial
statements.

BUSINESS RISKS AND UNCERTAINTIES

OUR DISPLAYS MAY NOT SUCCEED COMMERCIALLY.

Our microdisplays may not be accepted by a widespread market. Even if we
successfully mass-produce a display that is used in a retailed product, our
customers may determine not to introduce or may terminate the sale of products
utilizing the technology for a variety of reasons, including the following:

       -      superior technologies developed by our competitors;

       -      price considerations;

       -      lack of anticipated or actual market demand for the products; and

                                       10
<PAGE>   11

       -      difficulties in inducing companies to begin using our product.

A MARKET FOR OUR PRODUCTS MAY NOT DEVELOP.

Various target markets for our micro-displays, including projectors, monitors,
high-definition televisions, and portable micro-displays, are uncertain, may be
slow to develop, or could utilize competing technologies. High-definition
television has only recently become available to consumers, and widespread
market acceptance is uncertain. In addition, the commercial success of the
portable microdisplay market is uncertain. Gaining acceptance in this market may
prove difficult because of the radically different approach of microdisplays to
the presentation of information. In order for us to succeed, not only must we
sell to those manufacturers that produce end-products microdisplays that are
better and cheaper than the alternatives they would otherwise use, but also, the
manufacturers themselves must develop products that are successful commercially.
Failing to sell to manufacturers or the failure of the ultimate target markets
to develop as we expect will impede our anticipated growth.


WE MAY EXPERIENCE DIFFICULTIES MASS-PRODUCING MICRODISPLAYS.

We need to work closely with our manufacturing sources to commence volume
production of our current prototype. Problems in implementing volume production
or lower than expected manufacturing yields could significantly and adversely
affect us because we will have already incurred the costs for the materials used
in the microdisplay manufacturing process. These problems could cause delays
that might lead our potential customers to seek other sources.

We currently obtain silicon backplanes from the Far East. Some Asian countries
are subject to earthquakes and typhoons. Unless we obtain a second source, any
disruption or termination of our silicon manufacturing operations in Taiwan or
air transportation with the Far East could adversely affect our operations.

Our silicon backplanes are assembled in Hong Kong with electronic components to
create microdisplays. Because our assembly contract is relatively new we
anticipate that technical issues in the manufacturing process will need to be
resolved. The design and manufacture of LCDs and display modules are highly
complex processes that are sensitive to a wide variety of factors, including the
level of contaminants in the manufacturing environment, impurities in the
materials used, and the performance of personnel and equipment. Contract
manufacturers do not guarantee their manufacturing yields. In addition, the
complexity of manufacturing processes will increase along with increases in the
sophistication of our display modules. Low manufacturing yields or delivery
problems could adversely affect our operating results.

WE ARE INCURRING SUBSTANTIAL RESEARCH AND DEVELOPMENT COSTS.

We currently have ten engineers based in California working on prototype
microdisplays. This staffing creates significant research and development costs
that may not be recouped. We have sold our current prototypes to a number of
companies that have indicated they may be willing to incorporate them into
products if they could buy such displays in volume. As we begin the process of
working with third parties to manufacture our designs in volume, we are
continuing to use our engineers to develop subsequent generations of our
microdisplays. As a result, our overhead is expected to increase.

WE MUST FINANCE THE GROWTH OF OUR BUSINESS AND THE DEVELOPMENT OF NEW PRODUCTS.



                                       11
<PAGE>   12
We must continue to make significant investments in research and development,
equipment and facilities. Our failure to generate sales to offset our costs will
adversely affect our ability to continue operating.

We anticipate the need for additional equity or debt financing to provide for
the capital expenditures required to maintain our research and development and
to move to production. We cannot predict the timing or amount of any such
capital requirements at this time. If such financing is not available we may be
unable to continue our business activities. Equity financing could result in
additional dilution to existing stockholders. Debt financing increases expenses,
must be repaid regardless of operating results, and is secured against our
assets, potentially leaving fewer resources available for the benefit of equity
holders.

OUR OPERATING RESULTS ARE NEGATIVE AND SUBJECT TO FLUCTUATIONS.

We have not achieved profits in the past five years and have experienced cash
shortages. We will need to achieve substantial sales to support our cost
structure before we can begin to recoup our operating losses and accumulated
deficit. Any progress toward profitability may not be steady and may be subject
to significant periodic or seasonal quarterly fluctuations due to factors
including the following:

       -      introductions of displays and market acceptance of new or new
              generations of displays;

       -      timing of expenditures in anticipation of future orders;

       -      changes in our cost structure;

       -      availability of labor and components;

       -      pricing and availability of competitive products and services;

       -      the timing of orders;

       -      the volume of orders relative to the capacity we can contract to
              produce;

       -      evolution in the life cycles of customers' products; and

       -      changes or anticipated changes in economic conditions.

WE ARE SUBJECT TO LENGTHY DEVELOPMENT PERIODS AND PRODUCT ACCEPTANCE CYCLES.

Our business model requires us to develop microdisplays that perform better than
existing technologies, contract with one or more third-party manufacturers to
manufacture our prototypes in bulk, and sell the resulting displays to original
equipment manufacturers that will then incorporate it into their products. OEMs
make the determination during their product development programs whether or not
to incorporate our display modules in their products. This requires us to invest
significant amounts of time and capital in designing display modules well before
our customers introduce their products incorporating these displays and before
we can be sure that we will generate any significant sales to our customers or
even recover our investment. Even if a product is successful for a short period,
competition from other sellers could limit the length of time it is successful.

SHORTAGES OF COMPONENTS AND MATERIALS MAY DELAY OR REDUCE OUR SALES AND INCREASE
OUR COSTS.



                                       12
<PAGE>   13

Our inability to obtain sufficient quantities of components and other materials
necessary to produce our displays could result in reduced or delayed sales or
lost orders. Any delay in or loss of sales could adversely impact our operating
results. We obtain many of the materials we use in the manufacture of our
displays from a limited number of foreign suppliers, particularly suppliers
located in the Far East, and we do not have long-term supply contracts with any
of them. As a result, we are subject to economic instability and currency
fluctuations in these countries as well as to increased costs, supply
interruptions, and difficulties in obtaining materials. Our customers also may
encounter difficulties or increased costs in obtaining from others the materials
necessary to produce their products into which our product solutions are
incorporated.

MARKET ACCEPTANCE OF THE PRODUCTS OF OUR CUSTOMERS IS AN IMPORTANT ELEMENT OF
OUR BUSINESS STRATEGY.

We do not sell any products to end-users. Instead, our business strategy
involves designing and manufacturing various product solutions that our
customers incorporate into their products. As a result, our success will depend
upon the widespread market acceptance of our customers' products. Any
significant slowdown in the demand for our customers' products would adversely
affect our business.

Our dependence on the success of the products of our customers will expose us to
a variety of risks, including our needs to do the following:

       -      maintain customer satisfaction with our design and manufacturing
              services;

       -      match our design and manufacturing capacity with customer demand
              and to maintain satisfactory delivery schedules;

       -      anticipate customer order patterns, changes in order mix, and the
              level and timing of orders that we can meet; and

       -      adjust to the cyclical nature of the industries and markets we
              serve.

Our failure to address these risks may cause us to lose sales or for sales to
decline.

WE FACE INTENSE COMPETITION.

We serve intensely competitive industries that are characterized by price
erosion, rapid technological change, and competition from major domestic and
international companies. This intense competition could result in pricing
pressures, lower sales, reduced margins, and lower market share. Some of our
competitors have greater market recognition, larger customer bases, and
substantially greater financial, technical, marketing, distribution and other
resources than we possess. As a result, they may be able to introduce new
products and respond to customer requirements more quickly than we can.

Our competitive position could suffer if one or more of our customers decide to
design and manufacture their own display modules, to contract with our
competitors, or to use alternative technologies. In addition, in our industry
customers typically develop second sources. Second source suppliers may win an
increasing share of a program by competing primarily on price rather than on
design.

Our ability to compete successfully depends on a number of factors, both within
and outside our control. These factors include the following:



                                       13
<PAGE>   14

       -      our success in designing and manufacturing new display
              technologies;

       -      our ability to address the needs of customers;

       -      the quality, performance, reliability, features, ease of use,
              pricing, and diversity of our display products;

       -      foreign currency fluctuations, which may cause a foreign
              competitor's products to be priced significantly lower than our
              displays;

       -      the quality of our customer services;

       -      the efficiency of our production sources;

       -      the rate at which customers incorporate our displays into their
              own products; and

       -      products or technologies introduced by our competitors.

WE DO NOT HAVE LONG-TERM PURCHASE COMMITMENTS FROM OUR PROSPECTIVE CUSTOMERS.

Our prospective customers have not yet provided us with firm or long-term volume
purchase commitments. Although we have begun to negotiate with our customers, we
currently do not have any contracts with our customers. Because we have no firm,
long-term volume purchase commitments we do not have clear order lead times. In
addition, our prospective customers can cancel purchase commitments or reduce or
delay orders at any time. The cancellation, delay, or reduction of customer
commitments could result in our holding excess and obsolete inventory or having
unabsorbed manufacturing overhead. Our sales to customers in the electronics
industry, which is subject to severe competitive pressures, rapid technological
change, and product obsolescence, increases our inventory and overhead risks.

OUR COMMON STOCK MAY NOT BE LIQUID.

We are currently traded on the Nasdaq SmallCap. Any swing in the price of our
stock may be magnified into a material reduction in price because relatively few
buyers may purchase our stock.

THE ELECTRONICS INDUSTRY IS CYCLICAL.

The electronics industry has experienced significant economic downturns at
various times, characterized by diminished product demand, accelerated erosion
of average selling prices, and production over-capacity. In addition, the
electronics industry is cyclical in nature. We may experience substantial
period-to-period fluctuations in future operating results because of general
industry conditions or events occurring in the general economy.

WE MUST EFFECTIVELY MANAGE OUR GROWTH.

The failure to manage our growth effectively could adversely affect our
operations. Our ability to manage our planned growth effectively will require us
to:

       -      enhance our operational, financial, and management systems;



                                       14
<PAGE>   15

       -      expand our facilities and equipment; and

       -      successfully hire, train, and motivate additional employees,
              including technical staff.

As we expand our overhead and selling expenses will increase. We also may be
required to increase staffing and purchase capital equipment. Customers,
however, generally do not commit to firm production schedules for more than a
short time in advance. Any increase in expenditures in anticipation of future
sales that do not materialize would adversely affect our profitability.


WE MUST PROTECT OUR INTELLECTUAL PROPERTY.

Our success will depend in part on protecting our proprietary technology. Third
parties could claim that we are infringing their patents or other intellectual
property rights. In the event that a third party alleges that we are infringing
its rights, we may not be able to obtain licenses on commercially reasonable
terms from the third party, if at all, or the third party may commence
litigation against us. The failure to obtain necessary licenses or other rights
or the institution of litigation arising out of such claims could materially and
adversely affect us.

We rely on a combination of patent law, trade secret law, attempts to limit
disclosure of our confidential information and contractual provisions to protect
our intellectual property. Trade secret laws and contractual provisions afford
only limited protection. We face risks associated with our intellectual
property, including the following:

       -      pending patent applications may not be issued;

       -      patents issued to us may be challenged, invalidated, or
              circumvented;

       -      unauthorized parties may obtain and use information that we regard
              as proprietary despite our efforts to protect our proprietary
              rights;

       -      others may independently develop similar technology or design
              around any patents issued to us;

       -      intellectual property laws may not protect our intellectual
              property; and

       -      effective protection of intellectual property rights may be
              limited or unavailable in some foreign countries, in which we may
              operate.

WE DEPEND ON KEY PERSONNEL.

Our development and operations depend substantially on the efforts and abilities
of our senior management and technical personnel. The competition for qualified
management and technical personnel is intense. We are currently seeking a
permanent CEO and CFO. The loss of services of one or more of our key employees
or the inability to add key personnel could have a material adverse affect on
us.

THE MARKET PRICE OF OUR COMMON STOCK MAY BE VOLATILE.

The market price of our common stock has been extremely volatile, reflecting
reported losses, receipt of additional financing and changes to management.
Other companies have found similar volatility



                                       15
<PAGE>   16

correlates with class action securities law suits. The trading price of our
common stock in the future could continue to be subject to wide fluctuations in
response to various factors, including the following:

       -      quarterly variations in our operating results;

       -      actual or anticipated announcements of technical innovations or
              new product developments by us or our competitors;

       -      public announcements regarding our business developments;

       -      changes in analysts' estimates of our financial performance;

       -      general conditions in the electronics industry; and

       -      worldwide economic and financial conditions.

In addition the stock market has experienced extreme price and volume
fluctuations that have particularly affected the market prices for many
high-technology companies and that often have been unrelated to the operating
performance of these companies. These broad market fluctuations and other
factors may adversely affect the market price of our common stock.

SALES OF LARGE NUMBERS OF SHARES COULD ADVERSELY AFFECT THE PRICE OF OUR COMMON
STOCK.

Many of our outstanding shares are freely tradable without restrictions or
further registration. Sales of substantial amounts of common stock by our
stockholders, or even the potential for such sales, may affect the market price
of our common stock and could impair our ability to raise capital through the
sale of our equity securities.

WE COULD BE LIABLE IN CONNECTION WITH PRODUCT LIABILITY CLAIMS.

Product liability claims may be asserted against us in the event that the use of
our products, or products which incorporate our products, are alleged to cause
injury or other adverse effects. Our product liability insurance may not be
adequate to protect us against potential claims. As a result a successful claim
against us could materially affect our financial stability. In addition, our
reputation may be affected by product liability claims regardless of the merit
or eventual outcome of the claim.

WE FACE RISKS ASSOCIATED WITH INTERNATIONAL TRADE AND CURRENCY EXCHANGE.

Political and economic conditions abroad may adversely affect the foreign
manufacture and sale of our displays. Protectionist trade legislation in either
the United States or foreign countries, such as a change in the current tariff
structures, export or import compliance laws, or other trade policies, could
adversely affect our ability to manufacture or sell displays in foreign markets
and to purchase materials or equipment from foreign suppliers.

WE DO NOT PAY CASH DIVIDENDS.



                                       16
<PAGE>   17

We have never paid any cash dividends on our common stock and do not anticipate
that we will pay cash dividends in the near term. Instead, we intend to apply
earnings to the expansion and development of our business.

PART II.  OTHER INFORMATION
