ITEM 1. DESCRIPTION OF BUSINESS
 
INTRODUCTION
 
    Spatialight, Inc. ("Spatialight" or the "Company") is in the business of
designing, producing and commercializing miniature, high-resolution active
matrix liquid crystal displays ("LCDs"), also known as spatial light modulators
("SLMs") for computer and video display applications. SLMs are designed in a
manner that can potentially provide high quality images at a significant
reduction in costs over other types of computer and video displays currently
available in the market. The SLMs are designed to be capable of handling
computer and video output at very high speeds, clarity and contrast. The
Company's first SLM product is a .75" diagonal, 704 x 512 pixel, two-dimensional
array on 20 micron centers which is manufactured domestically in very limited
quantities. To date, the Company has sold only small volumes of its first SLM
product to customers involved in the research and development of applications
for this technology, including computer monitors, head-mounted displays, optical
computing and other projection applications.
 
    The Company has identified a number of potential applications and markets
for products based on its SLM technology, including light-weight computer
projection systems, large computer monitors and head-mounted displays for use in
defense and aerospace applications and for computer training and gaming devices.
In addition, the Company believes that its SLM products may have application in
optical computing systems and in high-speed, large-capacity optical data storage
systems and holographic imaging systems.
 
    The address and telephone number of the Company's principal executive
offices are 8-C Commercial Boulevard, 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 its name
to Sayett Group, Inc. and, in June 1996, changed its name again to Spatialight,
Inc. Spatialight, Inc. holds 80% of the outstanding stock of Spatialight of
California. Prior to 1996, Spatialight, Inc. operated subsidiaries that were in
the businesses of manufacturing populated circuit boards and manufacturing LCD
projection equipment. Both of these businesses were sold in 1995 and are
accounted for as discontinued operations. See "Management's Discussion and
Analysis" and Notes to Consolidated Financial Statements--Note 5. Unless the
context requires otherwise, all references herein to Spatialight or the Company
refer collectively to Spatialight, Inc., Spatialight of California and their
wholly owned subsidiaries.
 
TECHNOLOGY AND PRODUCTS UNDER DEVELOPMENT
 
    The Company's only currently available product is a .75" diagonal, 704 x 512
pixel, two-dimensional array on 20 micron centers. This product is manufactured
in very small quantities domestically. The Company currently has under
development a 1024 x 768 pixel SLM product, which it anticipates will be
commercially available in limited quantities for evaluation and development uses
in mid 1997. The Company's SLMs are based on an advanced, proprietary technology
for using liquid crystal directly over the surface of a silicon chip to convert
reflected external light into high-resolution images.
 
    The technology underlying the Company's SLM products relies on the
manipulation of liquid crystal. A liquid crystal display ("LCD") consists of
liquid crystal material between two pieces of glass, and associated polarizers.
Rotating the polarization of the molecules in the liquid crystal changes the
liquid crystal medium from opaque to transparent and can thereby control the
transmission of light. The liquid crystal material has long tubular molecules
with a natural twist. The molecules untwist in response to an applied electric
field. As the molecules untwist, light can pass through the liquid crystal and
its glass encasement. Commonly available projection panels generally use
super-twisted nematic ("STN") LCDs. Molecules in STN LCDs have a high degree of
twist and are very responsive to an applied electric field. The Company's SLMs
are designed to use the STN molecules by encasing them directly at the surface
of an integrated circuit on a silicon chip. The chip generates the polarizing
electric fields which can be
 
                                       3
<PAGE>
controlled by and therefore display a signal from a computer, cable television,
a video cassette recorder or other type of high information content source. The
chip has a substrate manufactured with complimentary metal oxide semiconductor
 .8 micron processes that enables high-speed processing of computer and video
output with high contrast and resolution. Display glass is applied to the
surface of the silicon chip with a "spin on" technology to improve flatness.
Improved flatness should enhance display quality and increase display size
capability by reducing defects that would otherwise be magnified, and help
maintain light efficiency to reduce power use.
 
    The Company's SLMs are being designed to compete with other technologies
that produce color LCDs. Additive color techniques require each dot or picture
element ("pixel") on the display screen to be divided into three sub-pixels. A
color filter is applied to each sub-pixel, causing each subpixel to transmit
red, green or blue light. The viewer's eye combines the colored light from the
three sub-pixels to create the perception of the full spectrum of colors.
Additive technologies, also referred to as "color filtered" technologies,
include both passive and active matrix approaches. To date, active matrix has
been most commonly accomplished through the use of thin film transistor
technology ("TFT"), in which a transistor is placed on the glass substrate at
each sub-pixel location and is used to control that sub-pixel. TFT displays are
currently manufactured in commercial quantities by Japanese manufacturers and
are relatively expensive. Further, TFT technology relies on the display being
relatively small, because manufacturing costs and the costs of applying the
display increase dramatically with size.
 
    The Company believes that the technology underlying its SLM products may
provide certain advantages over TFT or other display products or technologies.
The Company's 704 x 512 product offers gray scaling at 256 levels per pixel. The
Company's SLMs are expected to ultimately cost less to manufacture than
comparable TFT displays because of the fundamental chip technology and the
placement of the pixel format directly onto a silicon wafer. Further, Company
testing indicates that its SLMs are capable of being approximately 100 times as
light efficient as currently available TFT displays. The Company's 1024 x 768
product under development has a 90% fill factor with 20 micron pixel pitch.
 
    Although the Company has demonstrated SLM devices based on its core
technology, and recently entered into a contract to produce an engineering
prototype of a consumer product for mass production, the Company has not yet
produced any prototype SLM products with quality and resolution sufficient to
satisfy commercial end-use applications. Delays in development may result in the
Company's introduction of its products later than anticipated, which may have an
adverse effect on both the Company's financial and competitive position.
Moreover, there can be no assurance that the Company will ever be successful in
developing or manufacturing a commercially viable SLM device or any of its
proposed display products. In addition, there is no assurance that an SLM device
or any of the Company's display products will be technically or commercially
successful or that the Company will be able to manufacture or obtain a supplier
for adequate quantities of its SLM devices or any of its display products at
commercially acceptable cost levels or on a timely basis.
 
    The electronic imaging display industry has undergone rapid and significant
technological change. The Company expects the technology to continue to develop
rapidly, and the Company's success will depend significantly on its ability to
attain and maintain a competitive position. Rapid technological development may
result in actual and proposed products or processes becoming obsolete before the
Company recoups a significant portion of related research and development,
acquisition and commercialization costs. If the Company is successful in the
development of a commercially viable SLM device, the Company's ability to
compete will depend in part upon the consistency of product quality and
delivery, as well as pricing, technical capability and servicing, in addition to
factors within and outside its control, including the success and timing of
product introductions by the Company and its competitors, product performance
and price, product distribution and customer support. There can be no assurance
that the Company's competitors will not succeed in developing technologies and
products that are equally or more effective than any which are being developed
by the Company or that will render the Company's technology, SLM devices or
display and other products obsolete and non-competitive.
 
                                       4

    APPLICATIONS AND MARKETS
 
    The Company believes that current and future SLM products may be
incorporated into a wide variety of monitors, projectors and other light
engines. The Company also believes that suppliers and manufacturers of display
products may desire to license the Company's technology for use in such end
products. The Company does not plan, nor does it have the financial resources,
to develop or market any end products itself. Therefore, the Company will be
completely dependent upon independent third parties for the development,
manufacturing and marketing of such products. No such products exist today, and
the Company does not have commitments from any third party for such development,
manufacturing or marketing. There can be no assurance that any third party will
develop or market a product incorporating the Company's SLM's. If not, there
will be no market for the Company's SLM's. However, the Company has entered into
a development project with Packard Bell Electronics with the goal of
incorporating the Company's SLMs into Packard Bell's monitor products in the
future. The Company has also established informal arrangements with suppliers of
light engine components, including lamps, screen materials and lenses. The
Company believes these relationships are important to its ability to succeed
because they can enable the Company to demonstrate potential application
solutions to customers. The failure to establish relationships with suppliers of
light engine components and other manufacturers could make it more difficult for
the Company to gain market acceptance for its products. To encourage
manufacturers to design products that integrate the Company's SLMs, the Company
intends to offer prototypes at low cost for evaluation and design into products.
However, because many manufacturers are unfamiliar with reflective technology
displays, and because of their limited supply, the Company may experience
difficulty in convincing manufacturers to use its SLMs.
 
MARKETING, SALES AND DISTRIBUTION
 
    The Company's SLMs are available directly from the Company or through the
Company's principal distributor, Meadowlark Optics. The Company has a
non-exclusive distribution agreement with Meadowlark to market the Company's
SLMs in low volumes primarily to large corporate research departments and
university research labs. Currently available SLMs, including necessary
electronics, have a per unit retail list price of $20,000.
 
    The Company currently employs no full-time sales or marketing specialists.
The Company intends to form alliances with corporate partners for the marketing
and distribution of certain of its anticipated display products. There can be no
assurance that the Company will be successful in forming and maintaining such
alliances or that the Company's partners will devote adequate resources to
successfully market and distribute these anticipated products. There can be no
assurance that the Company will be able to attract and retain qualified
marketing and sales personnel, that the Company will be able to enter into
satisfactory agreements with marketing partners, or that the Company or its
marketing partners will be successful in gaining market acceptance for its
anticipated products.
 
    MANUFACTURING AND SUPPLY
 
    The Company currently engages outside manufacturers to produce its SLM
devices, and the Company has no experience manufacturing SLM devices or display
products. The Company's facility is designed principally for research and
development and small-scale assembly and inventory storage. Final assembly and
testing of the SLM product is conducted by Company personnel prior to shipment.
The Company has established supplier relationships with both a low volume and a
high volume LCD filling processor. The Company does not have a written contract
with either such supplier, and accordingly, either of them may discontinue
providing LCD components to the Company at any time. Any such termination of
supply could have a material adverse effect on the Company's ability to meet its
commitments to customers while the Company identified and qualified a
replacement supplier. The Company is negotiating with several manufacturers for
establishment of full-scale integrated manufacturing capacity for its SLM
devices and has reached an agreement with one manufacturer for fabrication of
silicon wafers. However, no decision
 
                                       5
<PAGE>
has been made by any such manufacturer to establish such a capability and there
can be no assurance that any of them will do so. In the event any such
manufacturer establishes a full-scale integrated manufacturing capability, the
Company could become dependent on such manufacturer for the manufacture of SLM
devices. The termination or cancellation of the Company's agreement with the
manufacturer could adversely affect the Company's ability to manufacture its
products. In such event, the Company could be required to establish an
alternative manufacturing relationship or establish its own manufacturing
capability. There can be no assurance that the Company would be able to
establish such a relationship on acceptable terms or develop its own
manufacturing capability. In any event the time required to establish such a
substitute relationship or capability could substantially delay the
commercialization of the Company's SLM devices and display products, which, in
turn, could have a substantial adverse impact on the Company's results of
operations and financial condition.
 
COMPETITION
 
    The active matrix LCD market has been dominated by Japanese manufacturers
such as Sharp, Hitachi, Seiko-Epson, Sanyo and Toshiba (in partnership with
IBM). These manufacturers, however, have concentrated on larger format, eight to
ten inch displays used in portable computers. Other companies such as Kopin
Corporation, OIS Ovonics, Texas Instruments and Motif (a Motorola and InFocus
Systems joint venture) have attempted to design and produce small format LCDs
and SLMs with comparable functionality to that of the Company's SLMs. No
attempts at commercialization of the small format display devices have been
successful to date.
 
    The electronic imaging display industry has been characterized by rapid and
significant technological advances. There can be no assurance that the Company's
SLM devices and display products will be reflective of such advances or that the
Company will have sufficient funds to invest in new technologies or products or
processes. A number of companies in the United States assemble workstation
monitors using LCDs and cathode-ray tubes ("CRTs") purchased from Japan. A
number of Japanese companies build monitors around their LCDs and CRTs.
 
    Korean companies are also entering the LCD and CRT monitor market.
Development of improved high-definition LCDs and CRTs continues to receive
significant attention by these and other companies. Although the Company
believes that its SLM products have the capability to improve LCD performance
beyond that of commercially available LCD- and CRT-based display products, there
is no assurance that manufacturers of LCDs or CRTs will not develop further
improvements of LCD or CRT technology that would eliminate or diminish the
Company's anticipated advantage. In addition, numerous competitors have
substantially greater financial, technical and other resources than the Company.
The Company may face an aggressive, well financed competitive response that may
include misappropriation of the Company's intellectual property or predatory
pricing.
 
PATENTS AND INTELLECTUAL PROPERTY
 
    The Company's ability to compete effectively with other companies will
depend, in part, on the ability of the Company to maintain the proprietary
nature of its technologies. Although the Company has been awarded or has filed
applications for several patents in the United States, there can be no assurance
as to the degree of protection offered by these patents, or as to the likelihood
that pending patents will be issued. Furthermore, the Company has not yet
applied for or obtained any foreign patents. There can be no assurance that
competitors, in both the United States and foreign countries, many of which have
substantially greater resources and have made substantial investments in
competing technologies, will not seek to apply for and obtain patents that will
prevent, limit or interfere with the Company's ability to make and sell its
products or intentionally infringe the Company's patents. The defense and
prosecution of patent suits is both costly and time-consuming, even if the
outcome is favorable to the Company. This is particularly true in foreign
countries. In addition, there is an inherent unpredictability regarding
obtaining and enforcing patents in foreign countries. An adverse outcome in the
defense of a patent suit could
 
                                       6
<PAGE>
subject the Company to significant liabilities to third parties, require
disputed rights to be licensed from third parties, or require the Company to
cease selling its products. The Company also relies on unpatented proprietary
technology and there can be no assurance that others may not independently
develop the same or similar technology or otherwise obtain access to the
Company's proprietary technology. To protect its rights in these areas, the
Company requires all employees and most consultants, advisors and collaborators
to enter into confidentiality agreements. There can be no assurance, however,
that these agreements will provide meaningful protection for the Company's trade
secrets, know-how or other proprietary information in the event of any
unauthorized use, misappropriation or disclosure of such trade secrets, know-how
or other proprietary information. To date, the Company has no experience in
enforcing its confidentiality agreements.
 
RESEARCH AND DEVELOPMENT
 
    The Company incurred research and development expenses of approximately
$265,000 in 1996 and $509,766 in 1995. Research and development expenses
represent costs incurred, primarily personnel related, for the design and
development of new products and the redesign of existing products. The Company
believes that the development of new products will be required to allow it to
compete effectively and to achieve future revenues. The Company currently has 11
full time employees whose duties include research and development. The Company
intends to continue its product enhancement and development programs, focusing
on increasing the display size and finalizing field sequential color
capabilities and liquid crystal filling manufacturing processes. The Company
believes that such enhancements and new products will be required to exploit
future markets for large screen monitors, high definition television and head
mount displays.
 
EMPLOYEES
 
    As of December 31, 1996, the Company had 11 full-time and 4 part-time
employees. Employment is divided amount two functional areas with 12 in
engineering and 3 in finance and administration. Employees are not represented
by any collective bargaining organizations. The Company considers its relations
with its employees to be good.
 
    The Company is dependent upon its key scientific and management personnel,
including its Chief Executive Officer, William Hollis, and its Vice President,
Dean Irwin. The Company does not maintain key-man life insurance on Messrs.
Hollis or Irwin. In 1996, the Company entered into a three-year employment
agreement with Mr. Hollis and a two-year employment agreement with Mr. Irwin.
Both agreements are terminable by the Company for cause. The loss of the
services of one or more key individuals may have a material adverse impact on
the Company. The Company's success will also depend on its ability to attract
and retain other highly qualified scientific, marketing, manufacturing and other
key management personnel. The Company faces competition for such personnel and
there can be no assurance that the Company will be able to attract or retain
such personnel.
 
ITEM 2. DESCRIPTION OF PROPERTY
 
    The Company's headquarters are located at 8-C Commercial Drive, Novato,
California. Approximately 4,000 square feet of office space is leased through
April 1997. The Company anticipates that this lease will be extended for another
12 months. The Company believes that its current facilities will be sufficient
for its needs for at least the next year.
 
ITEM 3. LEGAL PROCEEDINGS.
 
    By letter dated January 13, 1997, counsel for Jalcanto, Ltd. and Sabotini,
Ltd. (the "Investors") notified the Company that these Investors were electing
to rescind the Share Purchase Agreements dated July 10, 1996, as amended (the
"Purchase Agreements"), under which the Investors purchased a total of
 
                                       7
<PAGE>
2,135,000 shares of common stock in the Company, and were demanding a refund by
January 17, 1997 of the purchase price of such shares, or $1,783,125, plus
interest. The alleged ground for rescission is the fact that the Company's
registration statement on Form S-3 pertaining to the resale of such shares was
not declared effective by the SEC on or before December 31, 1996. Subsequently,
by letter dated February 3, 1997, counsel for the Investors notified the Company
that Jalcanto, Ltd. had retracted its demand for rescission, with reservation of
all rights. The letter reiterated the rescission demand on behalf of Sabotini,
Ltd., and the request that the Company return $891,563.
 
    On February 5, 1997, the Company was served notice that it has been sued by
each of the Investors in the Superior Court of the State of California for the
County of Marin. Each Investor filed a complaint for breach of contract,
specific performance and indemnification relating to the alleged failure to
timely complete the contractually required registration statement. In addition,
each complaint requests that the court issue a preliminary and permanent
injunction against future issuances of shares of the Company's common stock or
securities convertible into common stock without the Investor's consent. The
complaint filed by Sabotini Ltd. also requests rescission and the return of the
full purchase price of its shares (approximately $892,000). On February 26,
1997, a hearing was held with respect to Sabotini's application for a writ to
attach the Company's funds in the amount of $920,000 to ensure enforceability of
any eventual judgment in Sabotini's favor. By order dated February 28, 1997, the
court denied the application for the writ without prejudice.
 
    The Company intends to defend itself vigorously in both actions and believes
that it is not probable that Sabotini will prevail in rescinding its Purchase
Agreement. The Company may be required to expend substantial funds and
management resources in connection with the defense and any settlement or
judgment; accordingly, the ultimate resolution of this litigation may have a
material adverse effect on the Company's business and financial condition taken
as a whole.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

ITEM 5. MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.
 
    The Common Stock of the Company has been traded in the over-the-counter
market since the Company's initial public offering on February 5, 1992. Until
April 1, 1997, the Common Stock was listed on the NASDAQ SmallCap Market under
the symbol "SLHT". NASD delisted the Company from the Nasdaq SmallCap Market
effective April 2, 1997 because the Company does not meet the $2,000,000 minimum
total asset requirement for continued listing. Trading in the Company's Common
Stock after April 2, 1997 has been conducted in the over-the-counter market in
the so-called "pink sheets" or the NASD's "OTC Bulletin Board". As a result of
the delisting, the liquidity of the Company's securities may be impaired, not
only in the numbers of securities which could be bought and sold, but also
through delays in the timing of transactions, reduction in security analysts'
and news media coverage of the Company, and lower prices for the Company's
securities than might otherwise be obtained.
 
    The following table sets forth, for the calendar quarters indicated, the
range of high and low quotations for the Common Stock, as reported by the
National Association of Securities Dealers Automated Quotation System.

    For a recent reported quotation for the Company's Common Stock, see the
cover page of this Form 10-KSB. The quotations listed above reflect inter-dealer
prices, without retail mark-up, mark-down or commission and may not represent
actual transactions.
 
    As of March 21, 1997, there were approximately 2,900 holders of record of
the Common Shares of the Company. The Common Stock represents the only class of
securities outstanding as of this filing.
 
    To date, the Company has not paid a dividend on its Common Stock. The
payment of future dividends is subject to the Company's earnings and financial
position and such other factors, including contractual restrictions, as the
Board of Directors may deem relevant and it is unlikely that dividends will be
paid in the foreseeable future.
 
    During 1996, the Company sold securities in private placement transactions
as follows. On July 11, 1996 the Company sold 1,585,000 shares of its common
stock at a price of $1.125 per share in cash, and concurrently issued warrants
to purchase an additional 1,585,000 shares of the Company's common stock (the
"Warrants"). The shares sold and the Warrants were acquired on identical terms
and in identical amounts by Sabotini, Ltd. and Jalcanto, Ltd., each of which are
Isle of Man corporations (the "Investors"). The Warrants are exercisable at any
time prior to July 15, 2001, at an exercise price of $1.00 per share before July
15, 1997, $1.25 per share though July 1999 and $1.50 per share thereafter. On
November 11, 1996, the Investors approved certain amendments to the Company's
covenants under their original share purchase agreements, and the Company agreed
to reprice the July 11, 1996 sale of common stock from $1.125 per share to
$0.8352 per share. As a result, the Company issued an additional 550,000 shares
of its common stock, evenly divided between the two Investors.
 
    No underwriter took part in the sale of stock to the Investors, and there
were no underwriting discounts or commissions; however the Company paid certain
finders fees in connection with the transaction. Net proceeds received by the
Company relating to the placement were $1,525,237. In making this private
placement of securities, the Company claimed the exemption from registration
under Section 4(2) of the Securities Act of 1933, as amended, pertaining to
transactions not involving a public offering. In claiming this exemption, the
Company relied upon factual information provided in representations by each
Investor concerning its financial position, sophistication and suitability as a
participant in such an exempt transaction.
 
ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS
 
    The statements in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" that relate to future plans, events or
performance are forward-looking statements which involve risks and
uncertainties. Actual results, events or performance may differ materially from
those anticipated in these forward-looking statements as a result of a variety
of factors, including those discussed throughout "Item 1--Description of
Business" and elsewhere in this Annual Report on Form 10-KSB/A. Readers are
cautioned not to place undue reliance on these forward-looking statements, which
speak only as of the date hereof. The Company undertakes no obligation to
publicly release the result of any revisions to these forward-looking statements
that may be needed to reflect events or circumstances after the date hereof or
to reflect the occurance of unanticipated events.

    NET SALES.  The Company's net sales were $176,100 and $95,857 in 1996 and
1995 respectively. These amounts are comprised of sales of a small number of
units of the Company's initial SLM device.
 
    OPERATING EXPENSES.  Operating expenses during 1996 and 1995 were $1,403,412
and $2,522,457, respectively. The substantial decrease in operating expenses
from 1995 to 1996 was principally due to the write off of goodwill in 1995.
 
    Costs of sales represent product costs associated with the production of
prototype SLMs. Costs of sale were $141,290 and $32,786 in 1996 and 1995,
respectively. The increase was due to the higher volume of SLM sales and high
costs associated with the production of prototype units during 1996. Cost of
sales was 80% of sales for 1996, and more than 100% of sales during the third
and fourth quarters of 1996 because of the low volume of sales, primarily
reflecting prototype and custom applications.
 
    Selling, general and administrative costs were $763,575and $503,940 in 1996
and 1995, respectively. The increase of 52% from 1995 levels reflects the
Company's initial investment in marketing the SLMs as it continued the
transition from research and development company to an operating company. Also
as a result of this transition, research and development expenses in the year
ended December 31, 1996 were $265,142, which represents a 48% decrease from
research and development expenses of $509,766 in the year ended December 31,
1996.
 
    On December 29, 1995 the Company sold Sayett Technology, Inc. (STI), a
wholly owned subsidiary, to former management members of the Company for
$300,000 in the form of a note receivable. In 1996, the Company received $51,526
in cash and $15,069 in furniture and fixtures toward payment of this note
receivable. In the third quarter of 1996 the Company wrote down the note by
$121,702 based on their assessment of collectability. After further discussions
with the purchasers of STI in December 1996 and January 1997 regarding their
ability to repay the note, the Company concluded that collectibility of the
remaining balance was unlikely. As a result, the Company wrote off the remaining
balance of $111,703 in the fourth quarter of 1996.
 
    The 1995 goodwill write-off resulted from the impairment of goodwill
associated with the purchase of a majority interest in Spatialight of California
during the first quarter of 1995. At the time of purchase, it was anticipated
that the sales of SLMs from Spatialight of California would continue to increase
during the remainder of 1995 as production processes and component
specifications were finalized for commercialization. While the sales performance
of Spatialight of California showed substantial improvement during the second
and third quarters of 1995, the Company was unable to continue selling its
products to one of its major customers. As a result, the sales performance of
Spatialight of California declined to zero in the fourth quarter of 1995. This
decline, coupled with the sale of Sayett Technology, a subsidiary of the Company
focused on manufacturing LCD projection equipment, and the resultant diminished
prospects that vertical integration would be available for Spatialight of
California within the group of companies controlled by the Company led the
Company to conclude that such goodwill was substantially impaired.
 
    OTHER INCOME (EXPENSES)  Losses in investee companies was $424,714 in 1995.
The losses in 1995 resulted from the write-off of the Company's entire
investment in InterVision Systems, Inc. The Company purchased a 40% interest in
InterVision, a producer of head-mounted displays utilizing a wearable computer,
in 1994. Due to losses incurred by InterVision through the period ended December
31, 1995, the Company's investment was totally impaired. Although InterVision
continues to operate, funded principally by a government grant, the Company does
not anticipate that its investment will be recovered.
 
    Interest income was $63,776 and $63,427 in 1996 and 1995, respectively.
Interest income in 1996 was principally due to interest on the proceeds of a
private placement of the Company's Common Stock in July 1996.
 
    Other expenses were $13,252 and $2,705 in 1996 and 1995, respectively. The
increase from 1995 resulted principally from expenses incurred in moving the
Company's headquarters to California.
 
                                       10
<PAGE>
    LOSS FROM CONTINUING OPERATIONS.  Losses from continuing operations were
$1,178,738 and $2,791,990 in 1996 and 1995, respectively. The Company
anticipates that losses from continuing operations will increase during 1997.
 
    DISCONTINUED OPERATIONS.  Total losses from discontinued operations were
$1,863,393 in 1995. During 1995, the Company sold Surmotech, Inc., a wholly
owned subsidiary which focused on manufacturing populated circuit boards, for
$188,000 in cash. During 1995, the Company also sold Sayett Technology, Inc., a
wholly owned subsidiary which focused on developing and manufacturing electronic
presentation systems, for a $300,000 note receivable.
 
    The consistent, recurring losses sustained by both companies prompted the
Company to make the sales. The operating results of the two entities have been
combined and reported as "losses from discontinued operations, net of income
tax." Net sales from the discontinued operations in the year ended December 31,
1995 were approximately $5,462,000.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    As of December 31, 1996, the Company had $1,324,398 in cash and cash
equivalents. Accounts receivable at December 31, 1996 totaled $40,201 and
represented primarily amounts due on SLMs shipped in the fourth quarter. The
Company's net working capital at December 31, 1996 was approximately $1,249,000.
 
    Net cash used by operating activities totaled $904,354 and $36,252 in 1996
and 1995, respectively. Net cash provided by investing and financing activities
in 1996 was approximately $1,550,000, principally resulting from a private
placement of the Company's Common Stock. Net cash used by investing and
financing activities in 1995 was approximately $423,000, principally resulting
from capital expenditures and purchase of an equity investment in InterVision
Systems, Inc.
 
    As of December 31, 1996, the Company had an accumulated deficit of
$7,464,081. The Company has realized significant losses in the past and expects
that these losses will continue at least through 1997. It is likely that the
Company will have quarterly and annual losses in 1997 and beyond. The Company
has generated limited revenues and no profits from operations. The development,
commercialization and marketing of the Company's products will require
substantial expenditures for the foreseeable future. Consequently, the Company
may continue to operate at a loss for the foreseeable future and there can be no
assurance that the Company's business will operate on a profitable basis.
 
    The Company is experiencing negative cash flow from operations resulting in
the need to fund ongoing operations from financing activities. The future
existence and profitability of the Company is dependent upon its ability to
obtain additional funds to finance operations and expand operations in an effort
to achieve profitability from operations. No assurance can be given that the
Company's business will ultimately generate sufficient revenue to fund the
Company's operations on a continuing basis. The matters discussed above, among
others, may indicate that the Company will be unable to continue as a going
concern for a reasonable period of time.
 
    Most of the Company's revenue to date has been derived from research and
development contracts and limited sales of its SLM devices. Although the Company
has demonstrated SLM devices based on its core technology, the Company has not
yet produced any prototype SLM products with quality and resolution sufficient
to satisfy commercial end-use applications. The Company recently entered into a
contract to produce an engineering prototype of a consumer product for mass
production. However, further development and testing will be necessary before
this product or the Company's other proposed products will be available for
commercial end-use applications. Delays in development may result in the
Company's introduction of its products later than anticipated, which may have an
adverse effect on both the Company's financial and competitive position.
Moreover, there can be no assurance that the Company will ever be successful in
developing or manufacturing a commercially viable SLM device or any of its
 
                                       11
<PAGE>
proposed display products. In addition, there is no assurance that an SLM device
or any of the Company's display products will be technically or commercially
successful or that the Company will be able to manufacturer adequate quantities
of its SLM devices or any of its display products at commercially acceptable
cost levels or on a timely basis.
 
    By letter dated January 13, 1997, counsel for Jalcanto, Ltd. and Sabotini,
Ltd. (the "Investors") notified the Company that these Investors were electing
to rescind the Share Purchase Agreements dated July 10, 1996, as amended (the
"Purchase Agreements"), under which on July 11, 1996 the Investors purchased a
total of 2,135,000 shares of common stock in the Company, and were demanding a
refund by January 17, 1997 of the purchase price of such shares, or $1,783,125,
plus interest. The alleged ground for rescission is the fact that the Company's
registration statement on Form S-3 pertaining to the resale of such shares was
not declared effective by the SEC on or before December 31, 1996. Subsequently,
by letter dated February 3, 1997, counsel for the Investors notified the Company
that Jalcanto, Ltd. had retracted its demand for rescission, with reservation of
all rights. The letter reiterated the rescission demand on behalf of Sabotini,
Ltd., and the request that the Company return $891,563.
 
    On February 5, 1997, the Company was served notice that it has been sued by
each of the Investors in the Superior Court of the State of California for the
County of Marin. Each Investor filed a complaint for breach of contract,
specific performance and indemnification relating to the alleged failure to
timely complete the contractually required registration statement. In addition,
each complaint requests that the court issue a preliminary and permanent
injunction against future issuances of shares of the Company's common stock or
securities convertible into common stock without the Investor's consent. The
complaint filed by Sabotini Ltd. also requests rescission and the return of the
full purchase price of its shares (approximately $892,000). On February 26,
1997, a hearing was held with respect to Sabotini's application for a writ to
attach the Company's funds in the amount of $920,000 to ensure enforceability of
any eventual judgment in Sabotini's favor. By order dated February 28, 1997, the
court denied the application for the writ without prejudice.
 
    The Company intends to defend itself vigorously in both actions and believes
that it is not probable that Sabotini will prevail in rescinding its Purchase
Agreement. The Company may be required to expend substantial funds and
management resources in connection with the defense and any settlement or
judgment; accordingly, the ultimate resolution of this litigation may have a
material adverse effect on the Company's business and financial condition taken
as a whole.

ITEM 7.  FINANCIAL STATEMENTS
 
                            INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of
Spatialight, Inc. and Subsidiary:
 
    We have audited the accompanying consolidated balance sheets of Spatialight,
Inc. and subsidiary (the "Company") as of December 31, 1996 and 1995, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the years 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 audits.
 
    We conducted our audits 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 audits provide a reasonable basis for our opinion.
 
    In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Spatialight, Inc. and
subsidiary as of December 31, 1996 and 1995, and the results of their operations
and their cash flows for the years then ended in conformity with generally
accepted accounting principles.
 
    The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in Note
2 to the consolidated financial statements, successful completion of the
Company's development program and ultimately, the attainment of profitable
operations, is dependent on future events including obtaining adequate financing
to fulfill its development activities, successful launching of the commercial
production and distribution of its products and achieving a level of sales
adequate to support the Company's cost structure. As discussed in Note 4, to the
consolidated financial statements, the Company is the defendant in litigation
brought by shareholders who purchased common stock in 1996. As further discussed
in Note 2 to the consolidated financial statements, the Company's recurring
operating losses and its accumulated deficit raise substantial doubt about its
ability to continue as a going concern. Management's plans concerning these
matters are also described in Note 2. The consolidated financial statements do
not include any adjustments that might result from the outcome of these
uncertainties.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                     YEARS ENDED DECEMBER 31, 1996 AND 1995
 
1. DESCRIPTION OF BUSINESS
 
    Spatialight, Inc. and its subsidiary (the Company) develops, designs,
manufactures, and markets high content information display system components for
the optical computing, computer monitoring/projection, holography, and
multimedia industries.
 
2. GOING CONCERN UNCERTAINTY
 
    The Company incurred significant operating losses in each of the last five
fiscal years and incurred a net loss in fiscal 1996 of $1,178,438. Additionally,
as of December 31, 1996 the Company's accumulated deficit totaled $7,464,081.
The Company has generated limited revenues to date and the development,
commercialization and marketing of the Company's products will require
substantial expenditures in the foreseeable future. Cost of sales was 80% of
sales for 1996, and more than 100% of sales during the third and fourth quarters
of 1996 because of the low volume of sales, primarily representing prototype and
custom applications.
 
    The successful completion of the Company's development program and
ultimately, the attainment of profitable operations, is dependent upon future
events. These events include the obtaining adequate financing to fulfill its
development activities, successful launching of the commercial production and
distribution of its products and achieving a level of sales adequate to support
the Company's cost structure. The accompanying consolidated financial statements
have been prepared on a going concern basis, which contemplates the realization
of assets and the satisfaction of liabilities in the normal course of business.
These matters discussed above, among others, may indicate that the Company will
be unable to continue as a going concern for a reasonable period of time.
 
    The consolidated financial statements do not include any adjustments
relating to the recoverability and classification of recorded asset amounts or
the amounts and classification of liabilities that might be necessary should the
Company be unable to continue as a going concern.
 
    In an effort to improve operating performance, the Company has been and will
be implementing certain programs and strategies in 1997. These strategies
include:
 
    - Raising of additional capital.
 
    - Outsourcing of all manufacturing activities, which will be monitored by
      Company's manufacturing/ quality control engineering staff.
 
    - Developing strategic arrangements with potential customers to share
      development costs and/or licensing of the Company's technology.
 
    - Construction of engineering models to demonstrate proof of technology for
      OEM's.
 
    The Company's continuation as a going concern is dependent upon its ability
to generate sufficient cash flow to meet its obligations on a timely basis, to
obtain additional financing, and ultimately to attain successful operations.
Management is continuing its efforts to obtain additional funds so that the
Company can meet its obligations and sustain its operations.

revenues and expenses during the reporting period. Actual results could differ
from those estimates.
 
    INVENTORIES--Inventories are stated at the lower of cost or market, cost
being determined on a first-in, first-out (FIFO) basis.
 
    PROPERTY AND EQUIPMENT--Property and equipment are recorded at cost while
repairs and maintenance costs are expensed in the period incurred. Depreciation
and amortization of property and equipment is calculated on a straight-line
basis over the estimated useful lives of the assets, generally 3 to 5 years.
 
    REVENUE RECOGNITION--Revenue is generally recognized at the time product is
shipped.
 
    INCOME TAXES--The Company uses the asset and liability method to account for
income taxes, in accordance with Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes."
 
    NET LOSS PER COMMON SHARE--Net loss per common share for 1996 and 1995 is
based on the weighted average number of common shares outstanding during the
year; stock options and warrants were not included since their effect would be
anti-dilutive.
 
    RESEARCH AND DEVELOPMENT--Research and development costs are charged to
expense when incurred.
 
    CASH EQUIVALENTS--Cash equivalents include money market securities stated at
cost, which approximate market value, purchased with original maturities of
three months or less.
 
    STOCK-BASED COMPENSATION--The Company accounts for stock-based awards to
employees using the intrinsic value method in accordance with APB No. 25,
"Accounting for Stock Issued to Employees."
 
4. ISSUANCE OF COMMON STOCK AND RELATED LITIGATION
 
    On July 11, 1996 the Company sold 1,585,000 shares of its common stock to a
private investor group at $1.125 per share, or $1,783,125 in gross proceeds. In
conjunction with the sale of common stock, the Company also issued warrants to
purchase an additional 1,585,000 shares of the Company's common stock,
exercisable at any time prior to July 15, 2001, at an exercise price of $1.00
per share before July 15, 1997, $1.25 through July 1999 and $1.50 thereafter.
Net proceeds received by the Company related to this placement were $1,525,237.
 
    On November 11, 1996, in connection with the approval by the above-mentioned
investors of a future additional offering of common stock (relating to the
Company's planned stock for stock exchange to acquire the remaining 20% of
common shares of SOC owned by the original owners), the Company entered into an
Amendment Agreement which repriced the July 11, 1996 sale of common stock from
$1.125 per share to $.8352 per share and issued an additional 550,000 shares to
the investors.

4. ISSUANCE OF COMMON STOCK AND RELATED LITIGATION (CONTINUED)
    By letter dated January 13, 1997, counsel for Jalcanto, Ltd. and Sabotini,
Ltd. (the "Investors") notified the Company that these Investors were electing
to rescind the Share Purchase Agreements dated July 10, 1996, as amended (the
"Purchase Agreements"), under which on July 11, 1996 the Investors purchased a
total of 2,135,000 shares of common stock in the Company, and were demanding a
refund by January 17, 1997 of the purchase price of such shares, or $1,783,125,
plus interest. The alleged ground for rescission is the fact that the Company's
registration statement on Form S-3 pertaining to the resale of such shares was
not declared effective by the SEC on or before December 31, 1996. Subsequently,
by letter dated February 3, 1997, counsel for the Investors notified the Company
that Jalcanto, Ltd. had retracted its demand for rescission, with reservation of
all rights. The letter reiterated the rescission demand on behalf of Sabotini,
Ltd., and the request that the Company return $891,562.50.
 
    On February 5, 1997, the Company was served notice that it has been sued by
each of the Investors in the Superior Court of the State of California for the
County of Marin. Each Investor filed a complaint for breach of contract,
specific performance and indemnification relating to the alleged failure to
timely complete the contractually required registration statement. In addition,
each complaint requests that the court issue a preliminary and permanent
injunction against future issuances of shares of the Company's common stock or
securities convertible into common stock without the Investor's consent. The
complaint filed by Sabotini Ltd. also requests rescission and the return of the
full purchase price of its shares (approximtely $892,000). On February 26, 1997,
a hearing was held with respect to Sabotini's application for a writ to attach
the Company's funds in the amount of $920,000 to ensure enforceability of any
eventual judgment in Sabotini's favor. By order dated February 28, 1997, the
court denied the application for the writ without prejudice.
 
    The Company intends to defend itself vigorously in both actions and believes
that it is not probable that the Sabotini will prevail in rescinding its
Purchase Agreement. The Company may be required to expend substantial funds and
management resources in connection with the defense and any settlement or
judgment; accordingly, the ultimate resolution of this litigation may have a
material adverse effect on the Company's business and financial condition taken
as a whole. No provision for any loss that may result from resolution of this
uncertainty has been made in the accompanying consolidated financial statements.
 
5. DISCONTINUED OPERATIONS
 
    On July 1, 1995 the Company sold Surmotech, Inc., a wholly owned subsidiary,
for $188,000 in cash.
 
    On December 29, 1995 the Company sold Sayett Technology, Inc., (STI) a
wholly owned subsidiary, to former management members of the Company for
$300,000 in the form of a note receivable. In 1996, the Company received $51,526
in cash and $15,069 in furniture and fixtures. In the third quarter of 1996 the
Company wrote down the note by $121,702 based on their assessment of
collectibility. After further discussions with the purchasers of STI in December
1996 and January 1997 regarding their ability to repay the note, the Company
concluded that collectibility of the remaining balance was unlikely. As a
result, the Company wrote off the remaining balance of $111,703 in the fourth
quarter of 1996.
 
    As a result of the aforementioned sales, the Company is reporting the
results of the two subsidiaries as discontinued operations for the period ended
December 31, 1995 in the consolidated financial statements. Net sales from
discontinued operations were $5,462,000 in 1995.

7. INVESTMENT IN SUBSIDIARY
 
    In November 1992, the Company entered into a Subscription and Stock Purchase
Agreement (the Agreement) with SOC (formerly WAH-III Technology Corp.) a
development stage company that develops, designs and manufactures electronic
display products, including a small, high content liquid crystal display (LCD).
Through the Agreement and subsequent amendments, the Company purchased and held,
as of December 31, 1994, notes receivable totaling $1,078,105. Additionally, the
Company made advances to SOC under a line of credit agreement totaling $200,000
as of December 31, 1994.
 
    On January 1, 1995, the Company converted its note receivable from SOC and
received 2,703,427 shares of SOC common stock which increased its ownership of
SOC to approximately 68%. On February 7, 1995, the Company exchanged 354,543
shares of its common stock for 531,815 shares of SOC common stock, which further
increased its ownership to approximately 80.3%. The note receivable conversion
and exchange of shares in 1995 gave rise to a difference between the Company's
investment and the underlying equity in the net assets of SOC. This excess of
purchase price over the net assets acquired ("goodwill") totaled $1,475,965. The
Company wrote off the $1,475,965 of goodwill in December 1995, based in part on
a comparison of the Company's best estimate of the undiscounted cash flows of
SOC to the carrying value of the goodwill.
 
    The operating results of SOC have been included in the Company's
consolidated financial statements since January 1, 1995. The absence of a
minority interest balance on the consolidated balance sheet as of December 31,
1996 and 1995 is due to a deficiency in SOC's net assets due to its recurring
losses. Additionally, losses applicable to the minority interest have been
charged against the Company's interest, as there is no obligation of the
minority interest to make good such losses.
 
8. LOSS IN INVESTEE COMPANY
 
    On March 26, 1994, the Company acquired 40% of the common stock of
InterVision Systems, Inc. (ISI), a newly formed Delaware Corporation that
produces head-mounted displays utilizing a wearable computer, for $1,350,000.
The Company accounted for this investment using the equity method of accounting
which required that the original investment be recorded at cost and adjusted by
the Company's share of undistributed earnings or losses of ISI. ISI generated a
loss of approximately $925,286 for the period ended December 31, 1994. The
Company lost an additional $424,714 for the nine months ended September 30,
1995, indicating that the Company's investment was and continued to be
significantly impaired. The Company measured the impairment of its investment by
recording 100% of the loss

generated by ISI in the consolidated financial statements since the Company
essentially provided 100% of ISI's capitalization and therefore, had all the
capital-at-risk. As of December 31, 1995 Company's investment has been totally
written-off.

9. INCOME TAXES (CONTINUED)
    A valuation allowance is provided when it is more likely than not that some
portion of the deferred tax asset will not be realized. The Company has
established a 100% valuation allowance at December 31, 1996 and 1995 due to
uncertainty of realizing future tax benefits from its net operating loss
carryforwards and other deferred tax assets.
 
    As discussed in Note 5, the Company sold two subsidiaries during 1995. Any
tax benefits arising from the disposal of these subsidiaries were completely
offset by an increase in the Company's valuation allowance.
 
    At December 31, 1996, the Company had net operating loss ("NOL")
carry-forwards of approximately $4,700,000, available to offset United States
taxable income. The NOL carry-forwards will expire from 2005 to 2011.
 
    Income taxes (refunded) paid in 1996 and 1995 totaled $5,330 and $(1,912)
respectively.
 
10. STOCKHOLDERS' EQUITY
 
    STOCK OPTION PLAN--The Company has various Stock Option Plans primarily for
employees and directors. The Plans authorize the issuance of options to purchase
up to 1,010,000 shares of the Company's common stock. The Plans provide for
options which may be issued as nonqualified or qualified incentive stock options
under Section 422A of the Internal Revenue Code of 1986, as amended.
 
    Under the 1991 and 1993 Employee Stock Option Plans, the Company may grant
options to purchase up to 915,000 shares of common stock to employees at prices
not less than the fair market value at the date of grant for incentive stock
options and not less than 85% of fair market value for non-statutory stock
options. These options expire 10 years from the date of grant and become
exercisable 50% in year one and 50% in year two.
 
    Under the 1993 Non-Employee Directors' Stock Option Plan non-employee
directors of the Company are granted options to purchase 10,000 shares of common
stock at the fair market value at the date of grant each year that such person
remains a director of the Company. These options expire 10 years from the date
of grant and become fully exercisable after 2 years. The total number of shares
authorized under the plan is 95,000.
 
    Options under the Plans are granted at the discretion of the Board of
Directors. All options granted through 1996 have been granted at fair market
value.

ADDITIONAL STOCK PLAN INFORMATION
 
    Statement of Financial Accounting Standards No. 123, ACCOUNTING FOR
STOCK-BASED COMPENSATION, (SFAS 123) requires the disclosure of pro forma net
loss and loss per share had the Company adopted the fair value method as of the
beginning of fiscal 1995. Under SFAS 123, the fair value of stock-based awards
to employees is calculated through the use of option pricing models, even though
such models were developed to estimate the fair value of freely tradable, fully
transferable options without vesting restrictions, which significantly differ
from the Company's stock option awards. These models also require subjective
assumptions, including future stock price volatility and expected time to
exercise, which greatly affect the calculated values. The Company's calculations
were made using the Black-Scholes option pricing model with the following
weighted average assumptions: expected life, 10 years; stock volatility, 183% in
1996 and 183% in 1995; risk free interest rates, 6.89% in 1996 and 6.59% in
1995; and no dividends during the expected term. The Company's calculations are
based on a multiple option valuation approach and forfeitures are recognized as
they occur. If the computed fair values of the 1995 and 1996 awards had been

10. STOCKHOLDERS' EQUITY (CONTINUED)
amortized to expense over the vesting period of the awards, pro forma net loss
would have been $4,714,233 ($.75 per share) in 1995 and $1,299,513 ($0.18 per
share) in 1996. However, the impact of outstanding non-vested stock options
granted prior to 1995 has been excluded from the pro forma calculation;
accordingly, the 1995 and 1996 pro forma adjustments are not indicative of
future period pro forma adjustments, when the calculation will apply to all
applicable stock options.
 
    On February 25, 1997 the Company repriced the exercise price and extended
vesting period of all 365,000 outstanding options (originally granted from
$0.875 to $3.13) to $0.625.
 
11. MAJOR CUSTOMERS
 
    The Company had five customers during the year ended December 31, 1995. Two
of these customers accounted for 40% of the Company's sales.
 
12. COMMITMENTS AND CONTINGENCIES
 
    The Company has various operating lease arrangements for equipment and
office space. Total rent expense under operating leases amounted to
approximately $32,000 and $35,000 in 1996 and 1995, respectively. The office
lease expires on April 30, 1997 and future minimum lease payments under non-
cancelable operating leases are $12,000. The Company expects the lease to be
renewed for one year.
 
    CONTINGENT PAYMENT CONTRACTS--Prior to December 31, 1994, SOC entered into
certain contracts with service providers and with several employees to lease
space and obtain research, development, marketing, legal and other services.
These contracts provide for payments to these service providers and employees as
SOC achieves specified cumulative unit sales or revenue levels. There are no
required payments under the contracts if minimum cumulative unit sales or
revenue levels are not achieved. The contracts do not have expiration dates. As
of December 31, 1996 and 1995, services under these contracts have been provided
to the Company; however, no amounts have been accrued as a liability because
achievement of the minimum required cumulative unit sales or revenue levels is
not considered probable as of that date. As of December 31, 1996, the maximum
potential liability of the Company under these contracts is approximately
$1,100,000.
