                   FORWARD - LOOKING STATEMENTS AND IMPORTANT
                        FACTORS AFFECTING FUTURE RESULTS

         Our disclosure and analysis in this report contains some
forward-looking statements. Forward-looking statements give our current
expectations or forecasts of future events. They use words such as
"anticipate", "believe", "expect", "estimate", "project", "intend", "plan", and
other words and terms of similar meaning in connection with any discussion of
future operating or financial performance. In particular, these include
statements relating to future actions, prospective products or product
approvals, future performance or results of current and anticipated products,
sales efforts, expenses, the outcome of contingencies such as legal
proceedings, and financial results. From time to time, we also may provide oral
or written forward-looking statements in other materials we release to the
public.

         Any or all of our forward-looking statements in this report and in any
other public statements we make may turn out to be wrong. They can be affected
by inaccurate assumptions we might make or by known or unknown risks or
uncertainties. Many factors mentioned in the following discussion - for
example, product development, competition, and the availability of funding -
are important in determining future results. Consequently, no forward-looking
statement can be guaranteed. Actual future results may vary materially.

         We undertake no obligation to publicly update any forward-looking
statements, whether as the result of new information, future events, or
otherwise. You are advised, however, to consult any further disclosures we make
on related subjects in our 10-QSB, 8-K, and 10-KSB reports to the SEC. Also
note that we provide the following cautionary discussion of risks,
uncertainties, and possibly inaccurate assumptions relevant to our business.
These are factors that we think could cause our actual results to differ
materially from expected and historical results. Other factors besides those
listed here could also adversely affect us. This discussion is provided as
permitted by the Private Securities Litigation Reform Act of 1995.

OUR CFE PRODUCT DEVELOPMENT IS IN ITS EARLY STAGES AND THE OUTCOME IS UNCERTAIN

         Our Carbon Field Emission ("CFE") technology, and products that use
this technology, will require significant additional development, engineering,
testing and investment prior to commercialization. We have two leading
potential CFE products. The first is a Picture Element Tube, or PET, intended
for use initially in large indoor displays. If the PET is successful, we expect
to enhance it to allow it to be used in outdoor displays. The PET or displays
may not be successfully developed. We are also working on a product called the
HyFED, which combines what we believe to be the best properties of a cathode
ray tube ("CRT") and field emission display ("FED"). It is our intention to
license this technology to be used in the production of flat-screen TV
applications that are cost competitive with CRTs. If either of these products
are developed, it may not be possible for potential licensees to produce these
products in significant quantities at a price that is competitive with other
similar products.

WE HAVE NO CURRENT ROYALTY AGREEMENTS

         Our future strategy is dependent on licensing our technology to other
companies and obtaining royalties based on products that these licensees
develop and sell. We have no plans to manufacture and sell any CFE products
ourselves, and as such, we have no CFE product revenues. We signed a license
agreement in 1999, for a payment of approximately $5.6 million. We have no
other license agreements at the present time that will provide any future
revenues. It is our intention that all future license agreements will include a
provision that requires the payment of ongoing royalties.

OUR SUCCESS IS DEPENDENT ON OUR PRINCIPAL PRODUCTS AND TECHNOLOGY

         Our CFE technology is an emerging technology. Our financial condition
and prospects are dependent upon our licensing the technology to others and
upon market acceptance of our Electronic Billboard and other electronic display
products. Additional R&D needs to be conducted on the CFE technology before
others can produce products using this technology. Market acceptance of our
products and products using our technology will be dependent upon the
perception within the electronics and instrumentation industries of the
quality, reliability, performance, efficiency, breadth of application and
cost-effectiveness of the products. There can be no assurance that we will be
able to gain commercial market acceptance for our products or develop other
products for commercial use.


WE HAVE A HISTORY OF OPERATING LOSSES

         We have a history of operating losses. Our first profitable year was
1999, based on the strength of a license agreement of approximately $5.6
million signed in March 1999. We have incurred operating losses as shown below:

<TABLE>
<CAPTION>
                                                                Net Income
                  Year Ended December 31                           (Loss)

                  <S>                                          <C>
                           1992                                 ($1,630,978)
                           1993                                 ($7,527,677)
                           1994                                 ($7,255,420)
                           1995                                ($14,389,856)
                           1996                                ($13,709,006)
                           1997                                 ($6,320,901)
                           1998                                 ($3,557,548)
                           1999                                  $1,118,134
</TABLE>


         Although we expect to be profitable in the future, we may not be. Our
profitability in 2000 is dependent on the signing of additional license
agreements. We may, however, continue to incur additional operating losses for
an extended period of time as we continue to develop products. We do, however,
expect the magnitude of those losses, if they continue, to decrease. Wallace
Sanders & Company, independent auditors of the Company, have expressed
uncertainty as to our ability to continue as a going concern based on our
accumulated losses from operations in prior years. See "Independent Auditors'
Report." We have funded our operations to date primarily through the proceeds
from the sale of our equity securities. In order to continue our transition
from a contract research and development organization to an organization with
ongoing operations, we anticipate that substantial product development
expenditures will continue to be incurred.


WE ARE EXPOSED TO LITIGATION LIABILITY

         We were sued in 1996 by a former customer of Plasmatron for damages
that the former customer claimed that it incurred as a result of the alleged
failure of the machine provided by Plasmatron to perform as intended. That suit
was settled in January 2000. The majority of that settlement was paid by a
bonding company that had provided a bond on the original contract. Other
guarantors on the original bond that may now be subject to liability as a
result of the bonding company's payment have sued us for indemnification. We
consider these claims to be without merit and expect to have no liability in
these suits; however, they are still pending.

         Various trade creditors have also filed suit to collect unpaid trade
amounts due. We expect these items to be resolved with no material impact on
our financial statements. If we were to become subject to a judgment that
exceeds our ability to pay, that judgment would have a material impact on our
financial condition and could affect our ability to continue in existence.


                                   Page iii
<PAGE>   5
WE HAVE FUTURE CAPITAL NEEDS AND THE SOURCE OF THAT FUNDING IS UNCERTAIN

         We expect to continue to incur substantial expenses for R&D, product
testing, production, manufacturing, product marketing, and administrative
overhead. The majority of R&D expenditures are for the development of our CFE
technology and our electronic billboard product. Our business model is based on
our installing electronic billboards at customer sites at our cost and then
deriving advertising revenues from the signs. This will require a significant
capital investment on our part. Our electronic billboard product is available
now and we are in the process of installing our first units. Some of our other
proposed products may not be available for commercial sale or routine use for a
period of up to two years. Commercialization of our existing and proposed
products will require additional capital in excess of our current capital. A
shortage of capital may prevent us from achieving profitability for an extended
period of time. Because the timing and receipt of revenues from the sale of
products will be tied to the achievement of certain product development,
testing, manufacturing and marketing objectives, which cannot be predicted with
certainty, there may be substantial fluctuations in our results of operations.
If revenues do not increase as rapidly as anticipated, or if product
development and testing and marketing require more funding than anticipated, we
may be required to curtail our expansion and/or seek additional financing from
other sources. We may seek additional financing through the offer of debt or
equity or any combination of the two at any time.

         We have developed a plan to allow us to maintain operations until we
are able to sustain ourselves on our own revenue. However, we only have the
existing resources, including commitments, to allow us to survive for a period
of approximately six months from the date of this report at our current
spending levels. We have been operating in this manner for an extended period
of time and we believe that we have the ability to continue to raise short term
funding, if necessary, to enable us to continue operations until our plan can
be completed. Our plan is primarily dependent on raising funds through the
licensing of our technology, revenue generated from the installation of our
electronic billboard product, and through debt and equity offerings.

         Our plan is based on current development plans, current operating
plans, the current regulatory environment, historical experience in the
development of electronic products and general economic conditions. Changes
could occur which would cause certain assumptions on which this plan is based
to be no longer valid. Our plan is primarily dependent on increasing revenues,
licensing our technology, and raising additional funds through additional debt
and equity offerings. If adequate funds are not available from operations or
additional sources of financing, we may have to eliminate, or reduce
substantially, expenditures for research and development, testing and
production of our products. We may have to obtain funds through arrangements
with other entities that may require us to relinquish rights to certain of our
technologies or products. These actions could materially and adversely affect
us.

RAPID TECHNOLOGICAL CHANGE COULD RENDER OUR PRODUCTS OBSOLETE AND WE MAY NOT
REMAIN COMPETITIVE

         The display industry is highly competitive and is characterized by
rapid technological change. Our existing and proposed products will compete
with other existing products and may compete against other developing
technologies. Development by others of new or improved products, processes or
technologies may reduce the size of potential markets for our products. There
is no assurance that other products, processes or technologies will not render
our proposed products obsolete or less competitive. Many of our competitors
have greater financial, managerial, distribution, and technical resources than
we do. We will be required to devote substantial financial resources and effort
to further R&D. There can be no assurance that we will successfully
differentiate our products from our competitors' products, or that we will
adapt to evolving markets and technologies, develop new products, or achieve
and maintain technological advantages.


                                    Page iv
<PAGE>   6
WE HAVE TECHNOLOGIES SUBJECT TO LICENSES

         As a licensee of certain research technologies through license and
assignment agreements with Microelectronics and Computer Technology
Corporation, we have acquired rights to develop and commercialize certain
research technologies. In certain cases, we are required to pay royalties on
the sale of products developed from the licensed technologies and fees on
revenues from sublicensees. We also have to pay for the costs of filing and
prosecuting patent applications. The agreement is subject to termination by
either party, upon notice, in the event of certain defaults by the other party.
We expect any royalty payments to be insignificant.

OUR PRODUCTS MAY NOT BE ACCEPTED BY THE MARKET

         Since our inception, we have focused our product development and R&D
efforts on technologies that we believe will be a significant advancement over
currently available technologies. With any new technology, there is a risk that
the market may not appreciate the benefits or recognize the potential
applications of the technology. Market acceptance of our products and products
using our technology will depend, in part, on our ability to convince potential
customers of the advantages of such products as compared to competitive
products. It will also depend upon our ability to train manufacturers and
others to use our products

WE HAVE LIMITED MANUFACTURING CAPACITY AND EXPERIENCE

         We have no established commercial manufacturing facilities in the area
of CFE technology in which we are conducting our principal research . At the
present time, we have no intention of establishing a manufacturing facility
related to our CFE technology. We are focusing our efforts on licensing our
technology to others for use in their manufacturing processes. The management
team has commercial manufacturing and marketing experience in other industries
and with other products in the display industry; however, we have no experience
in manufacturing our proposed CFE products.

          In August 1999, we acquired the assets of Sign Builders of America,
Inc. ("SBOA"). SBOA is a manufacturer of high quality signage and provided
significant assistance in the development of our electronic billboard product.
To the extent that any of our other products require manufacturing facilities,
we intend to contract with a qualified manufacturer.

WE ARE DEPENDENT ON THE AVAILABILITY OF MATERIALS AND SUPPLIERS

         The materials used in producing our current and future products are
purchased from outside vendors. In certain circumstances, we may be required to
bear the risk of material price fluctuations. We anticipate that the majority
of raw materials used in products to be developed by us will be readily
available. However, there is no assurance that the current availability of
these materials will continue in the future, or if available, will be
procurable at favorable prices.


                                    Page v
<PAGE>   7
WE MAY BE UNABLE TO ENFORCE OR DEFEND OUR OWNERSHIP AND USE OF PROPRIETARY
TECHNOLOGY

         Our ability to compete effectively with other companies will depend on
our ability to maintain the proprietary nature of our technology. Although we
have been awarded patents, have filed applications for patents, or have
licensed technology under patents that we do not own, the degree of protection
offered by these patents or the likelihood that pending patents will be issued
is uncertain. Competitors in both the United States and foreign countries, many
of which have substantially greater resources and have made substantial
investment in competing technologies, may already have, or may apply for and
obtain patents that will prevent, limit or interfere with our ability to make
and sell our products. Competitors may also intentionally infringe on our
patents. The defense and prosecution of patent suits is both costly and
time-consuming, even if the outcome is favorable to us. In foreign countries,
the expenses associated with such proceedings can be prohibitive. In addition,
there is an inherent unpredictability in obtaining and enforcing patents in
foreign countries. An adverse outcome in the defense of a patent suit could
subject us to significant liabilities to third parties. Although third parties
have not asserted infringement claims against us, there is no assurance that
third parties will not assert such claims in the future.

         We also rely on unpatented proprietary technology, and there is no
assurance that others will not independently develop the same or similar
technology, or otherwise obtain access to our proprietary technology. To
protect our rights in these areas, we require employees, consultants, advisors
and collaborators to enter into confidentiality agreements. These agreements
may not provide meaningful protection for our 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. While we have attempted to protect proprietary technology that we
develop or acquire and will continue to attempt to protect future proprietary
technology through patents, copyrights and trade secrets, we believe that our
success will depend upon further innovation and technological expertise.


WE MAY NOT BE ABLE TO PROVIDE SYSTEM INTEGRATION

         In order to prove that our technologies work and will produce a
complete product, we must ordinarily integrate a number of highly technical and
complicated subsystems into a fully-integrated prototype. There is no assurance
that we will be able to successfully complete the development work on some of
our proposed products or ultimately develop any market for those products.


THE LOSS OF KEY PERSONNEL COULD ADVERSELY AFFECT OUR BUSINESS

         Our future success will depend on our ability to attract and retain
highly qualified scientific, technical and managerial personnel. Competition
for such personnel is intense. We may not be able to attract and retain all
personnel necessary for the development of our business. In addition, much of
the know-how and processes developed by us reside in our key scientific and
technical personnel. The loss of the services of key scientific, technical and
managerial personnel could have a material adverse effect on us.

OUR REVENUES HAVE BEEN DEPENDENT ON GOVERNMENT CONTRACTS IN THE PAST

         In previous years, a significant part of our revenues were derived
from contracts with agencies of the United States government. Following is a
summary of those revenues in recent years:

<TABLE>
<CAPTION>
                                      Revenues from      Percentage of
         Year Ended December 31       Gov. Contracts     Total Revenue

                   1992                   $930,000          99%
                   1993                 $1,147,000          89%
                   1994                   $820,000          41%
                   1995                 $1,009,000          33%
                   1996                 $2,869,000          50%
                   1997                   $854,000          24%
                   1998                         $0           0%
                   1999                         $0           0%
</TABLE>


         We currently have no significant commitment for any future government
funding and do not intend to seek any government funding unless it directly
relates to achievement of our strategic objectives.

         Contracts involving the United States government are, or may be,
subject to various risks including, but not limited to, the following:

         -        Unilateral termination for the convenience of the government
         -        Reduction or modification in the event of changes in the
                    government's requirements or budgetary constraints
         -        Increased or unexpected costs causing losses or reduced
                    profits under fixed-price contracts or unallowable costs
                    under cost reimbursement contracts
         -        Potential disclosure of our confidential information to third
                    parties
         -        The failure or inability of the prime contractor to perform
                    its prime contract in circumstances where we are a
                    subcontractor
         -        The failure of the government to exercise options provided
                    for in the contracts
         -        The right of the government to obtain a non-exclusive,
                    royalty free, irrevocable world-wide license to technology
                    developed under contracts funded by the government if we
                    fail to continue to develop the technology

ITEM 1.  BUSINESS.

                            DESCRIPTION OF BUSINESS

GENERAL

         SI Diamond Technology, Inc., a Texas corporation, acting through its
subsidiaries, is engaged in the development of products and services based
principally on novel applications of thin films and the application of display
technologies. We believe that microelectronic and other applications of carbon
based thin film technology will play an important role in the electronics
industry. Our research is focused on identifying key applications of this
technology. Based on our research, we are currently engaged in the development
of products based on Carbon Field Emission ("CFE") technology and the
development of an electronic billboard and related electronic display products
based on existing technology. Electronic billboards and other electronic
display products would provide a market for the Company's Picture Element Tube
("PET") product when completed. During 1999, we introduced our electronic
billboard product. We also acquired the assets of Sign Builders of America,
Inc., a manufacturer of various types of high-quality signage. We believe that
our greatest growth opportunity lies in CFE products and the development of an
electronic billboard and other electronic display products.

         We were incorporated in Texas in 1987. Our directly and indirectly
owned subsidiaries are as follows:

</TABLE>


         Our business includes the development and commercialization of
electronic billboards and related electronic display products, the manufacture
and sale of all types of signage, and the development and commercialization of
CFE products. From time to time, we also conduct contract research and
development, primarily for United States governmental agencies. The business
efforts of SI Diamond have arisen out of the its interest in thin film
materials, notably thin carbon film, diamond film, and diamond-like carbon film
("DLC"). These interests have led us into microelectronics-related processes,
thin film based CFE products, and electronic billboards and related electronic
display products.

         We conduct our operations through our subsidiaries. EBT is engaged in
the development of an electronic billboard and related electronic display
products such as outdoor display devices for use in the fast food or other
industries. EBT will install its first electronic billboard on a customer's
premises in March 2000. SBOA manufactures and sells all types of signage. FEPET
is conducting research on the CFE technology. Where appropriate, we enter into
collaborations with third parties as discussed in greater detail under the
heading "Technology Agreements" later in this section.


                                    Page 1

         We incurred research and development expense of $1,475,655 in 1999 and
$1,167,673 in 1998. Some of our proposed products will require significant
additional development, engineering, testing and investment prior to
commercialization and certain of these proposed products may not be available
for commercial sale or routine use for a period of up to two years. There is no
assurance that all products currently under development will be successfully
developed, produced in commercial quantities on a cost-effective basis, or
marketed successfully.


BUSINESS GROUPS


         FIELD EMISSION PICTURE ELEMENT TECHNOLOGY, INC. FEPET is developing our
proprietary CFE technology. In the past, our research has concentrated on the
emission properties of diamond like substances. Diamond is a subset of carbon
and over the past year, our research has indicated that carbon is actually a
better emitter. Accordingly, our research is now focused in the broader area of
CFE Technology.

           One intended use for the technology is in a PET. The PET is a
unique, high brightness, multi-color display component intended for use
initially in outdoor billboards, indoor video walls, and alphanumeric displays.
This technology, when fully developed, would be a natural step in the
improvement of the Company's electronic billboard and other electronic
products. We are also developing a new display technology, the HyFED, which
combines what we believe to be the best properties of cathode ray tubes
("CRTs") and Field Emission Displays ("FEDs"). Our plans for this technology
are discussed in greater detail in the section entitled "Business Development
Strategies" later in this report.


         ELECTRONIC BILLBOARD TECHNOLOGY, INC. EBT was incorporated in January
1997 to focus on developing sun-readable display products for outdoor use. Its
primary product is an electronic billboard which will enable the outdoor
advertising industry to exploit the Internet and information revolution by
placing ads at different locations at different times. We completed development
of the electronic billboard in 1999. The product was met with great enthusiasm
by potential customers. In January 2000, we signed an agreement with Eckerd
Corporation, a subsidiary of JCPenney to install electronic billboards at two
Eckerd stores as part of a pilot program. We are also developing indoor
displays for indoor use that could be used as part of an overall point of
purchase advertising program in conjunction with the outdoor electronic
billboards. Our plans for the billboard and related products are discussed in
greater detail in the section entitled "Business Development Strategies" later
in this report.

         SIGN BUILDERS OF AMERICA, INC. SBOA was incorporated in August 1999 to
acquire the assets (including the right to use the name) and certain
liabilities of a company operating under the same name. SBOA is a manufacturer
of high quality signage with a broad customer base throughout the United
States. Prior to our acquisition of SBOA, they were a vendor of EBT's. SBOA
assisted in the development of the electronic billboard and now assembles and
installs the electronic billboard product.


BUSINESS DEVELOPMENT STRATEGIES

         OVERALL. We are primarily a technology company. We are focusing our
efforts on research, product development, and licensing our technology to
others. FEPET is focused on developing world class technologies using carbon
films for electron field emission applications. EBT is focused on the
introduction of its electronic billboard products. We currently have a
manufacturing facility that we acquired through our acquisition of SBOA to make
our electronic billboard product. We have no plans to establish any other
manufacturing facilities in the immediate future. To the extent that we need to
develop additional manufacturing capabilities, we intend to use manufacturing
partnerships, joint ventures, or arrange to have products manufactured through
contract manufacturers.


                                    Page 2
<PAGE>   11
         LICENSING AGREEMENTS. We have an extensive patent portfolio that we
have developed and acquired over the years. Licensing of this technology to
major companies in the display industry is a critical part of our overall
strategic plan and critical to achieving profitability in the short run. In
March 1999, we signed our first significant license agreement with Canon, Inc.
In exchange for a one-time, up-front payment of approximately $5.6 million,
Canon was granted a non-exclusive right to use a portion of our technology.
While we have had numerous discussions with other potential licensees, we have
no licensing agreements generating ongoing revenue at the present time. We
expect to sign multiple license agreements within the next year and we expect
that such license agreements will include an up-front payment and a continuing
royalty stream based on the products sold by the licensee. We have made
significant progress on our CFE technology since the time of the Canon license
agreement and believe our patent portfolio to be much more valuable than it was
at the time of the Canon license agreement.

         CFE PRODUCTS. The major short run focus of FEPET is the continued
development and commercialization of its CFE products. Our current research and
development efforts are focused on two main products - the PET and the HyFED.

         The PET is a basic display device which could be used in many display
applications, including the Company's electronic billboard. The PET that the
Company has under development contains 64 pixels, which are the basic unit or
picture element that makes up the image displayed on a video screen. The CFE
technology provides several advantages over the existing technologies used in
these areas. It generally has a higher image quality, better sunlight
readability, lower cost, lower energy usage, improved viewing angle and
excellent video capabilities. As soon as the product is commercially viable, we
plan to introduce it in our electronic billboard product. We would also target
other large display manufacturers that manufacture displays for such uses as
sports arenas, video walls, alphanumeric signs, etc. We have completed our
collaborative efforts with Diamond Pro-Shop Nomura Co., Ltd. ("DPN") that
commenced in September 1997 to develop a PET using the Company's CFE
technology. We have demonstrated that the PET works and are now working to
solve some remaining packaging issues related to the product. We expect to
solve these issues in the next few months and expect that the product will move
into the manufacturing stage at that point. We do not intend to manufacture
these PETs ourselves, but rather license other manufacturers to produce them.

         We have also developed a new display technology, the HyFED. HyFED
combines what we believe to be the best properties of cathode ray tubes and
Field Emission Displays using our proprietary diamond/carbon thin films. We
anticipate that the HyFED will achieve a high-quality thin display using the
existing manufacturing base of CRTs. The HyFED display has the potential to be
larger, brighter, and have higher resolution than conventional CRTs, while
still remaining cost-competitive with existing CRTs. In January 1999, we formed
an International Development Team to develop the first HyFED display. The
International Development Team is composed of six organizations - four from
Japan, one from Europe, and ourselves. The International Development Team
completed a working four inch monochrome prototype of the HyFED in January
2000. The team is now working to improve the prototype so that it is capable of
displaying a uniform full motion color video image on the screen. Each member
of the team is focusing on the development of a specific portion of the
prototype and each member is funding their own portion of the work. Upon
completion of the final prototype, these team members will be given the first
opportunity to license the HyFED technology. We expect to license our HyFED
technology in 2000.

         ELECTRONIC BILLBOARDS. We are focusing our marketing efforts for our
electronic billboard product on major national retailers for their use in
conjunction with their existing on-site signage. These billboards are smaller
in size than the full size billboards we are also developing. We are focusing
on these retailers because we expect them to generate higher advertising
revenue per square foot of signage than roadside billboards and accordingly be
more profitable to us. We intend to lease or operate the billboards through
joint venture arrangements with these retailers. To facilitate our entry into
this market, we signed a marketing agreement in 1998 with Vision Mark, LLC
("Vision Mark"), a Texas limited liability company, and a related consulting
and advisory services agreement with C&A Services LLC ("C&A"), a Texas limited
liability company, affiliated with Vision Mark. Vision Mark and C&A agreed to
represent the Company with several major high profile retailers defined as
"protected" customers by the agreements. In January 2000, we signed an
agreement with Eckerd Corporation, a subsidiary of JCPenney and one of Vision
Mark's protected customers, to install two billboards as part of a pilot
program.


                                    Page 3
<PAGE>   12
         We also have a contract to install an electronic billboard at a test
site for a major national billboard company. We have delayed work on this
contract to focus our efforts on marketing activities related to retailers. The
market potential for roadside billboards is substantial. The Outdoor
Advertising Association of America has indicated that over 275,000 large
roadside billboards exist in the United States. The advantages of our product
are expected to be significant. Billboard companies could benefit by increasing
revenues at each site by being able to sell the same space to different
advertisers at different times during the day. Advertisers could benefit
substantially because they will be able to reach their target audience with
greater precision. After the completion of a billboard at a test site, we
intend to attack the billboard market in phases.

         The target market for the first phase will be premium billboard sites
- those sites that generate monthly advertising revenues of approximately
$25,000 or more. It is estimated that there are approximately 700 of these
sites in the United States and another 1,500 outside of the United States. We
estimate that EBT could begin supplying billboards to meet the initial demand
for these sites within 6 months of installing its test sign under its existing
contract and obtaining funding for ongoing development and commercialization.
Once demand in the premium market has been met and increased manufacturing
volumes have lowered the unit manufacturing costs, EBT will target the
remaining billboard market.

         Our billboard is based on a proprietary version of a mature existing
technology. This technology is Vacuum Fluorescent Display ("VFD"). The VFD
technology is widely used in a variety of applications and is readily available
from many component suppliers. This product offers many advantages over
existing technologies used in the outdoor advertising industry. These include
full video capability, full color, wide viewing angle with excellent outdoor
readability, relatively low cost compared with competing technologies, and high
reliability.

         We are installing our first electronic billboard at a customer site in
March 2000. We are also developing an electronic billboard using Liquid Crystal
Display ("LCD") technology . The LCD billboard, when fully developed using our
patented technology, is expected to provide similar quality at a lower cost. As
we continue to develop our CFE technology, we expect to integrate the CFE
technology into our electronic billboard because of the advantages that it is
expected to provide related to cost and quality. Our CFE PET has 64 pixels
compared to 16 pixels in the similar sized VFD PET we are using in our existing
billboard. This should allow billboards using our CFE PETs to display a higher
quality picture. We expect our electronic billboard product to be successful
regardless of the timing of the availability of our CFE technology.

         OTHER ELECTRONIC DISPLAY PRODUCTS. EBT, in conjunction with Texas
Digital Systems, Inc. ("TDS"), a distributor to the fast food industry,
developed an outdoor electronic display for use in the fast food industry.
These units, primarily in 10.4" to 17" sizes, are readable outdoors in direct
sunlight and intended for use at the drive through window of fast food
restaurants. We received a royalty on all units sold by TDS through December
31, 1999, when the agreement was terminated. We have also developed similar
sized display units for indoor usage. We intend to market these smaller size
display units for both indoor and outdoor usage to national retail chains to be
used as part of a coordinated advertising program in conjunction with the
larger outdoor electronic billboard.

COMPETITION

         ELECTRONIC BILLBOARDS. We believe that the proprietary version of the
VFD technology that we have developed is superior to existing technology when
combining the issues of brightness, cost, and image quality required for
electronic billboards. Competing technologies include:

         -        Light Emitting Devices ("LED") which have a grainy picture,
                    do not allow certain colors to be viewed in direct sunlight,
                    and have a high initial cost
         -        Incandescent bulbs that are high maintenance and result in
                    poor graphics
         -        Electromechanical systems that have poor image qualities and
                    limited colors
         -        Liquid Crystal Displays ("LCD")

         We have also acquired a patent related to LCD technology and are
currently researching the feasibility of using a version of the LCD technology
in a large screen display. LCDs are attractive because they have a long
lifetime and an existing manufacturing base.


                                    Page 4
<PAGE>   13
         We are unaware of any other organizations developing an electronic
billboard using a technology similar to ours. However, this is an existing
technology used in many applications. Competition from other manufacturers
could develop at any time. There are several other companies either producing
or developing electronic billboards using other technologies.

         CFE PRODUCTS. One short term focus in this area is the development of
the PET to be used as a component in a large display. This component, which
provides the light source is the most vital and costly part of a large display,
accounting for approximately 25 - 30 % of its cost. Since the PET directly
equates to the visual quality and reliability of the display, the
characteristics of the PET are critical to a purchase decision. Competition for
the Company's PET will come from the technologies previously described in
connection with the Company's electronic billboard. It is expected that the
Company's PET will provide wider viewing angles, a wider range of operating
temperatures and a higher degree of brightness than existing technologies.

         There are other companies attempting to develop non-carbon based field
emission display technologies. It is our opinion that these technologies will
not be as cost efficient or demonstrate as high a level of brightness as the
CFE technology. In addition, these companies are attempting to develop these
technologies for use in computer screens rather than large display
applications.

TECHNOLOGY AGREEMENTS

         MCC. In 1998, we simplified our technology agreements with MCC, the
Austin-based consortium of North American Electronics leaders. We previously
licensed 144 patents and patent applications from MCC under an exclusive
arrangement. This licensing agreement was amended in 1997 and again in 1998 to
directly transfer 62 of these patents and patent applications related to the
CFE technology directly to the Company and return the remaining patents and
patent applications to MCC. We are obligated to pay MCC a royalty of 2% of
revenues related to the transferred patents. We can, however, offset certain
pre-defined expenses against these royalty payments. It is not expected that we
will be obligated to pay any royalties in the near future.

         DIAGASCROWN. In February 1995, we entered into a series of agreements
with DGC. Under these agreements, we agreed to collaborate with DGC on the
further development of CFE-related technology. We have the right to use the DGC
technology on a royalty-free basis. We jointly own with DGC all technology
developed under this, although DGC has agreed to assign its interest to us.
Consequently, we will have the sole authority to sublicense the technology
obtained under the collaboration, should we elect to do so. (See Note 12 to the
Consolidated Financial Statements). Under the terms of the original agreement,
we committed to perform $2.5 million of development in Russia. There is
disagreement as to the actual amount spent, but it is our position that we have
no remaining obligation under the agreement. The internal results that we have
achieved are far superior to those achieved through the collaborative efforts
in Russia and at present we are not using the technology developed under this
joint venture agreement in any manner.

         ADDVENT. In May 1995, we entered into the ADDVent joint venture
agreement with another electronics manufacturer to develop a 10-inch field
emission display under the Advanced Technology Program ("ATP") administered by
the National Institute of Science and Technology ("NIST"). The ATP contract
provided for expenditures of $7.0 million by us from 1995 through 1997. These
expenditures were to be funded 49% by NIST. Under the ATP, we will own the
rights to the technology, subject to the license rights of the United States
government and the rights of our partner to own the high-voltage driver which
it will develop under the ATP and which it will supply to us. Our right to our
partner's driver shall be exclusive for a period of two years following our
acceptance of the design. We manage this project and have made the majority of
the expenditures under this program. As of December 31, 1999, we have completed
our portion of the program, which resulted in the development of useable carbon
films for use in display applications. These carbon films achieved certain
specifications required in the display industry and are addressable,
patternable, and have achieved the minimum emission site density required. Our
joint venture participant has not yet completed the driver development.

PATENTS AND PROPRIETARY RIGHTS

         An important part of our product development strategy is to seek, when
appropriate, protection for our products and proprietary technology through the
use of various United States and foreign patents and contractual arrangements.


                                    Page 5
<PAGE>   14
         We own 44 issued patents, three allowed patents, and have 64 patent
applications pending before the United States Patent and Trademark Office. We
also have several unsubmitted patent applications in process. The patents,
allowances and applications relate to the CFE technology and other
technologies. In addition, there are foreign counterparts to certain United
States patents and applications. We consider our patent portfolio to be our
most valuable asset.

         The patenting of technology-related products and processes involves
uncertain and complex legal and factual questions. To date, no consistent
policy has emerged regarding the breadth of claims of such technology patents.
Therefore, there is no assurance that our pending United States and foreign
applications will issue, or what scope of protection any issued patents will
provide, or whether any such patents ultimately will be upheld as valid by a
court of competent jurisdiction in the event of a legal challenge. Interference
proceedings, to determine priority of invention, also could arise in any of our
pending patent applications. The costs of such proceedings would be significant
and an unfavorable outcome could result in the loss of rights to the invention
at issue in the proceedings. If we fail to obtain patents for our technology,
and are required to rely on unpatented proprietary technology, there is no
assurance that we can protect our rights in such unpatented proprietary
technology, or that others will not independently develop substantially
equivalent proprietary products and techniques, or otherwise gain access to our
proprietary technology.

         Competitors have filed applications for or have been issued patents
and may obtain additional patents and proprietary rights relating to products
or processes used in, necessary to, competitive with, or otherwise related to,
our patents. The scope and validity of these patents, the extent to which we
may be required to obtain licenses under these patents or under other
proprietary rights and the cost and availability of licenses are unknown. This
may limit our ability to license our technology. Litigation concerning these or
other patents could be protracted and expensive. If suit were brought against
us for patent infringement, a challenge in the suit by us as to the validity of
the other patent would have to overcome a legal presumption of validity. There
can be no assurance that the validity of the patent would not be upheld by the
court or that, in such event, a license of the patent to us would be available.
Moreover, even if a license were available, the payments that would be required
are unknown and could materially reduce the value of our interest in the
affected products. We do, however, consider our patents to be very strong and
easily defendable in any action that may be brought against us.

         We also rely upon unpatented trade secrets. No assurance can be given
that others will not independently develop substantially equivalent proprietary
information and techniques or otherwise gain access to our trade secrets or
disclose such technology or that we can meaningfully protect our rights to our
unpatented trade secrets.

         We require our employees, directors, consultants, outside scientific
collaborators and sponsored researchers and other advisors to execute
confidentiality agreements upon the commencement of employment or consulting
relationships with us. These agreements provide that all confidential
information developed or made known to the individual during the course of the
relationship is to be kept confidential and not disclosed to third parties
except in specific circumstances. In the case of employees, the agreements
provide that all inventions conceived by the individual shall be our exclusive
property. There is no assurance, however, that these agreements will provide
meaningful protection for our trade secrets in the event of unauthorized use or
disclosure of such information.

GOVERNMENT REGULATION

         Our products will be subject to extensive government regulation in the
United States and in other countries. In order to produce and market our
existing and proposed products, we must satisfy mandatory safety standards
established by the U.S. Occupational Safety and Health Administration ("OSHA"),
pollution control standards established by the U.S. Environmental Protection
Agency ("EPA") and comparable state and foreign regulatory agencies. We may
also be subject to regulation under the Radiation Control for Health and Safety
Act administered by the Center for Devices and Radiological Health ("CDRH") of
the U.S. Food and Drug Administration. We do not believe that our CFE products
will present any significant occupational risks to the operators of such
equipment. In addition, the CFE products are not expected to produce
significant hazardous or toxic waste that would require extraordinary disposal
procedures. Nevertheless, OSHA, the EPA, the CDRH and other governmental
agencies, both in the United States and in foreign countries, may adopt
additional rules and regulations that may affect us and our products.
Additionally, our arrangements with our customers and affiliates may subject
our products to export and import control regulations of the U.S. and other
countries.


                                    Page 6
<PAGE>   15
         In the past, a portion of our revenues have consisted of earnings
under U.S. government contracts, although we received no such revenue in 1998
or 1999 and currently have only one minor grant. Government contracts are
subject to delays and risk of cancellation. Also, government contractors
generally are subject to various kinds of audits and investigations by
government agencies. These audits and investigations involve review of a
contractor's performance on its contracts, as well as its pricing practices,
the costs it incurs and its compliance with all applicable laws, regulations
and standards. We are, and in the future expect to be, audited by the
government. Our ATP program is required to be audited in accordance with NIST
standards. We expect the results of these audits to have no material impact on
us.

EMPLOYEES

         As of March 14, 1999, we had 50 full-time employees, including four
executive officers. Within the next twelve months, if business conditions
support it, we expect to hire additional employees. We are not subject to any
collective bargaining agreements and we consider our relations with our
employees to be good.

Corporate Secretary since November 1, 1999. From August 1998 until he joined
the Company, Mr. Murray was engaged in the private practice of law. From April
1990 until August 1998, Mr. Murray was Senior Assistant General Counsel and
Assistant Corporate Secretary for Tracor, Inc.

ITEM 2.  PROPERTIES

         We lease a 10,000 square foot facility in Austin that is used for our
corporate headquarters and research and development activities under a lease
expiring in June 2004. The monthly rental is approximately $7,000. Our SBOA
subsidiary also leases a 10,000 square foot facility in Austin that it uses for
its manufacturing operations under a lease expiring in August 2000. The monthly
rent on this facility is approximately $5,000. We also lease offsite storage
space totaling approximately 2,200 square feet on a month to month basis.

         We believe that these facilities will be adequate for our anticipated
research, development, and manufacturing activities until additional products
or alternative applications are developed. If and when such additional products
or alternative applications are developed, we may be required to establish
additional facilities or enter into manufacturing agreements with others.

         We do not currently invest in real estate or interests in real estate,
real estate mortgages, or securities of or interests in persons primarily
engaged in real estate activities. However, the Company has no policy, either
for or against, making such investments.

ITEM 3.  LEGAL PROCEEDINGS

         On May 20, 1996, Semi-Alloys Company, a former customer of Plasmatron,
filed a complaint with the Supreme Court of the State of New York, County of
Westchester. The complaint names Plasmatron, SI Diamond, and Westchester Fire
Insurance Company as defendants. Semi-Alloys claims a breach of contract
related to $1 million of coating equipment that Plasmatron delivered in 1993,
prior to our ownership of Plasmatron. Semi-Alloys claims the equipment does not
perform as required under the contract. Semi-Alloys seeks to recover
compensatory, consequential and incidental damages. In January 2000, we agreed
to participate in a settlement agreement between the plaintiff and the other
defendant; notwithstanding our denial of any liability to the plaintiffs. We
agreed to pay a total of $450,000, of which $225,000 was due at signing. We
signed three notes payable for the balance of the settlement. These notes, in
the amount of $25,000, $100,000, and $100,000, are due in three months, nine
months, and eighteen months, respectively. In exchange for this settlement, and
upon payment of the notes, we received a complete release from further
liability from both the plaintiff and the co-defendant. The entire amount of
this settlement is included in accrued liabilities at December 31, 1999.

         On April 30, 1998, Universal Bonding Company, managing general agent
for Westchester Fire Insurance Company filed a complaint with the Superior
Court of New Jersey, Atlantic county. The Complaint named Richland Glass
Company, Inc., Robert Williams, Joan Williams, Bawa Singh, Narinder Singh,
Gaylord Evey and Doris Evey, all guarantors under the bond, as defendants. All
defendants were former owners, or associated with former owners, of Plasmatron.
Defendant Gaylord Evey filed an answer with the court naming Plasmatron, SI
Diamond, Nicholas Rettino, and the Rettino Insurance agency as third party
defendants and asking for indemnification by the third party defendants. A
separate indemnification claim filed by Richland Glass against the same third
party defendants was consolidated with this case. The amount of this claim is
to be determined at trial; however, any potential amounts due by the us are
dependent upon Westchester collecting from other guarantors on the bond, and
those guarantors succeeding in obtaining a judgement against us. Westchester
has released its claims against us. We consider this case to be without merit
and expect to have the case ultimately resolved in our favor.

     On July 20, 1998, TFI Telemark, Inc., a former vendor of Plasmatron, filed
a complaint in the County Court at Law No. 2 of Travis County, Texas against us
for debts of our subsidiary, Plasmatron. We were served with notice of this
suit on August 5, 1998. All amounts claimed as owing by TFI are recorded as
liabilities of Plasmatron in the our consolidated financial statements. We
believe that the ultimate resolution of this matter will not have a material
impact on our consolidated financial statements.

     On August 18, 1998, KDF Electronic & Vacuum Services, Inc., a vendor of
DTO, filed a complaint in the United States District Court for the Southern
District of New York against us for unpaid debts of our subsidiary, Diamond
Tech One, Inc. We were served with notice of this suit on October 14, 1998. We
settled this lawsuit for less than the full amount due in 1999.

     On January 28, 1999, Aetna Life Insurance Company, a former landlord of
DTO, filed a complaint in the 12th Judicial District Court, Travis County,
Texas against DTO as lessee, and the Company as guarantor, for unspecified
alleged damages occurring as a result of DTO's early termination of a lease.
DTO moved out of this facility with approximately nine months remaining on the
lease which called for monthly rental payments of approximately $17,000. We
contend that Aetna failed in its duty to mitigate damages and behaved in a
reckless manner, which resulted in damages to us and our property. We intend to
vigorously defend ourselves in this action. We believe that the ultimate
resolution of this matter will not have a material impact on our consolidated
financial statements.

     The Company and its subsidiaries are also defendants in various other
lawsuits of a non-material nature related to the non-payment of invoices when
due. It is expected that all such lawsuits will be settled for an amount no
greater than the liability recorded in the financial statements for such
matters and that settlement of such suits will not have a material financial
impact on us.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         There were no matters submitted to a vote of security holders during
the fourth quarter of 1999.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS

         Our common stock, $0.001 par value was traded on the Boston and
Pacific Stock Exchanges under the symbol "SDI", and was also traded via the
National Association of Securities Dealers Automated Quotation (NASDAQ) system
in the Small Cap Market under the symbol "SIDT". We were delisted by both
exchanges and the NASDAQ Small Cap Market in 1998 for failure to comply with
continued listing requirements, primarily related to the minimum share price
required to maintain our listing. Our common stock now trades via the NASDAQ
OTC Bulletin Board. The following table sets forth, on a per share basis for
the periods indicated, the high and low sale prices for the common stock as
reported by the NASDAQ system. These NASDAQ quotations reflect inter-dealer

         On March 14, 2000, the closing sale price for our common stock as
reported on the NASDAQ OTC Bulletin Board system was $3.46875. As of March 14,
2000, there were approximately 315 shareholders of record for our common stock.

         We have never paid cash dividends on our common stock, nor do we have
any plans to pay dividends. Our board of directors currently intends to invest
future earnings, if any, to finance expansion of our business. Any payment of
cash dividends in the future will be dependent upon our earnings, financial
condition, capital requirements, and other factors deemed relevant by our board
of directors. It is unlikely that any dividends on the common stock will be
paid in the foreseeable future.

          Information required in this Item 5 of our Annual Report on Form

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

         The following discussion should assist in understanding our financial
position and results of operations for the years ended December 31, 1999 and
1998. The Notes to our Consolidated Financial Statements included later in this
report contain detailed information that should also be read in conjunction
with this discussion.

                                    OVERVIEW

         Throughout 1999 and 1998, we continued our efforts to move from a
contract research and development organization toward commercial viability. We
made the decision to sell the operating assets of our DTO subsidiary in May
1998 to focus on our remaining higher potential subsidiaries. In 1999, we
accomplished significant milestones in each of our active subsidiaries. Our
FEPET subsidiary licensed a portion of its patents to Canon, Inc. in exchange
for a one-time, up-front payment of approximately $5.6 million. EBT introduced
its electronic billboard product in July 1999 and continued to refine it for
the remainder of the year. EBT also acquired substantially all of the assets of
Sign Builders of America, Inc. as of August 31, 1999. SBOA is a high quality
manufacturer of all types of signage and played a significant role in the
development of our electronic billboard, both before and after the acquisition.
We expect to continue our concentrated research and development of FEPET's
technology in 2000. We expect to begin installing our electronic billboards
beginning in March 2000.

                             RESULTS OF OPERATIONS

         1999 Compared to 1998. The Company had $6,752,104 in revenues during
1999, as compared with $721,841 during 1998. The main reason for the increase
was the $5,555,556 license fee received in 1999 from Canon, Inc. Commercial
(non-governmental) sales accounted for all revenues in both years. Our revenue
in 1999 came from FEPET, EBT, and SBOA in the amounts of $5,794,269, $300,282,
and $657,553, respectively. In 1998, we received revenues from DTO of $385,364,
EBT of $192,246, and FEPET of $144,231. The 1999 FEPET revenues were composed
of license fees of $5,555,556 and $238,713 of research revenues. The 1998
revenues were primarily the result of the sale of research services and of
selected equipment designed and constructed by FEPET in the research process.
The EBT revenue in both years was primarily the result of royalty payments from
TDS. The 1998 revenues for DTO are for the period from January 1, 1998 through
the date of the DTO sale on May 8, 1998. The SBOA revenue in 1999 was for the
period from September 1, 1999 through December 31, 1999. We had no revenue from
government funded projects in either 1999 or 1998. We did receive approval for
a minor grant near the end of 1999, that will result in approximately $67,000
of revenue in 2000. We may seek additional research grants in the future if
such grants are directly related to projects that we are already working on in
conjunction with its strategic objectives.

         We had a revenue backlog of approximately $278,000 at December 31,
1999. This is composed of approximately $211,000 from our SBOA subsidiary and
approximately $67,000 under a NASA grant that we received in late 1999. We had
no revenue backlog at December 31, 1998.

         For 1999, our costs of sales were $674,380, resulting in a margin of
90%, as compared with $1,592,225 and a negative margin of 121% during 1998.
This increase in margin resulted because our 1999 revenues were primarily from
royalties and license fees that have only nominal costs associated with them.
The negative margin in 1998 resulted primarily from the Company's DTO
subsidiary. DTO's average monthly revenue decreased in the months preceding the
sale in 1998, while its cost structure was kept in place to keep the
organization intact and its capacity at its previous level for prospective
buyers. We had negative margins because our DTO subsidiary operated
significantly below its facility capacity in the 1998 period. We expect to
maintain positive margins in the future as we continue to pursue license and
royalty agreements and begin to generate advertising revenue from electronic
billboards that we install.

         Our selling, general and administrative expenses increased from
$2,149,018 in 1998 to $3,356,675 in 1999. This increase results from a
combination of factors including increased overhead associated with our SBOA
subsidiary, professional fees associated with the SBOA and other potential
acquisitions, a $500,000 commission paid to an unrelated party in connection
with the Canon license agreement, and expenses associated with the introduction
of our electronic billboard.


                                    Page 11
<PAGE>   20
         Company sponsored research and development expenses increased in 1999
to $1,475,655 from $1,167,673 in 1998. Development expense related to our
electronic billboard product is the primary reason for the increase. We expect
to incur substantial expenses in support of additional research and development
activities related to the commercial development of our CFE and electronic
display technologies. We have one small government grant at the present time.
We may apply for others, but will only do so if those grants are specifically
related to activities the Company is already pursuing to accomplish strategic
objectives.

         The gain on disposal of assets of $771,515 in 1998 resulted primarily
from the sale of the operating assets of DTO in May 1998 for a total sale price
of approximately $2.2 million. The gain on disposal of assets in 1999 was the
result of the sale of our previous domain name, diamond.com, for $250,000 and
minor other equipment disposals. The Company had no marketable securities
portfolio in 1998 and therefore no gains or losses related to marketable
securities in that year. Taxes in 1999 are foreign taxes related to the Canon
license agreement. There were no foreign taxes in 1998.

         In 1998, the Company adopted Statement of Financial Accounting
Standards No. 130 "Reporting Comprehensive Income", which establishes standards
for reporting and displaying comprehensive income and its components in a full
set of general purpose financial statements. Comprehensive income (loss)
approximates the net income (loss) reported.

                              FINANCIAL CONDITION

         Our cash position increased from $2,636 at December 31, 1998 to
$348,832 at December 31, 1999. Net cash provided by operating activities was
$868,226 as opposed to cash used in operating activities of $3,536,784 in 1998.
The increase in cash provided by operations was primarily the result of the
license agreement signed with Canon, Inc. in 1999.

         Cash used in investing activities was $1,736,134 in 1999 as compared
with cash provided by investing activities in 1998 of $2,028,948. The cash used
in investing activities in 1999 was related to the construction of our
electronic billboard product, our purchase of the assets of SBOA, and our
investment of a portion of our operating funds in marketable securities. The
cash provided by investing activities in 1998 was the result of proceeds from
the sale of the operating assets of DTO, offset by minor capital expenditures.
No material commitments exist as of December 31, 1999 for future purchases of
capital assets.

         In 1998 and in early 1999, we continued to raise additional funds
through equity and debt funding to finance our operating losses. The net cash
provided by financing activities decreased from $1,509,472 in 1998 to
$1,214,104 in 1999. As a result of the license payment from Canon, Inc. we had
less of a need for additional financing. Also, a significant portion of the
proceeds from the issuance of common stock was the result of the exercise of
warrants and stock options in 1999, that had been issued in prior years.

         Based on the developmental stages of our technology, additional
financing will be necessary in the future. If all of the our warrants that were
outstanding as of December 31, 1999, and have not yet expired in 2000, were
exercised, we would collect proceeds of approximately $800,000. (See Note 10 to
the Consolidated Financial Statements.) Proceeds from the exercise of warrants
totaled approximately $650,000 in 1999 and $90,000 in 1998. Given that the
current price of our common stock is significantly above the exercise price of
our outstanding warrants, it is likely that a significant portion of the
outstanding warrants will be exercised in the near future. We may also receive
proceeds from the exercise of stock options. If all currently vested options
that have an exercise price below the market price of the Company's stock as of
March 14, 2000 were exercised, the Company would receive proceeds of
approximately $1.9 million.

         Following is a summary of debt and equity proceeds that the Company
has received from January 1, 1997 through the date of this filing:


                                    Page 12
<PAGE>   21
8% Convertible Debenture

         In February 1997, we closed an offering of an 8% convertible debenture
under Regulation S of the Securities Act of 1933. On March 7, 1997 we received
gross proceeds of $555,555, less expenses and discount of $55,755, for the
issuance of the debenture. The entire unpaid principal and accumulated interest
on the debenture was due and payable on the second anniversary of the date on
which the debenture was issued. The debenture was converted into common stock
in accordance with the terms of the agreement as described below.

         The lender converted $83,334 of principal into 196,439 shares of our
common stock in December 1997. The conversion price was 75% of the average of
the closing bid price of our common stock for the 10 trading days preceding the
notice of conversion. In May 1998 the lender converted an additional $200,000
of principal into 1,469,119 shares of our common stock. The conversion price
was equal to the average closing bid price of our common stock for the calendar
month preceding the date of conversion (April 1998). In December 1998, the
lender converted the remaining $272,221 of principal and $61,592 of accrued
interest into 942,044 shares of our common stock. The conversion price was
based on 95% of the average of the closing bid price of our stock for the 10
trading days preceding the notice of conversion. As of December 31, 1999, we
have no remaining obligation to the former holder of the debenture.

Series F Preferred Stock

         In March 1997, we closed an exempt offering under Regulation D of the
Securities Act of 1933 for 1,700 shares of our Series F convertible preferred
stock. We received net proceeds of $1,527,500, which represented gross proceeds
of $1,700,000, less expenses of $172,500. Each share had a liquidation
preference of $1,000 plus 4% per annum from the date of issuance. Each share of
Series F preferred was convertible into that number of shares of common stock
determined by dividing the original issue price of the Series F preferred
stock, plus an accretion amount equal to 4 % of the issue price per annum, by
the conversion price. The conversion price was the lesser of $1.75 or 80% of
the 10 day average closing bid price prior to the conversion date. The Series F
preferred stock bears no dividends and holders of the Series F preferred stock
have no voting power except in certain circumstances pursuant to Texas state
law.

         On March 17, 1998, we revised our Amended and Restated Articles of
Incorporation pursuant to an agreement with the Series F shareholders. Under
the terms of this agreement, the Series F shareholders were allowed to convert
one-sixth of the number of Series F preferred shares held as of March 17, 1998
in each of the months from March 1998 through August 1998 into our common
stock. The conversion price for each month was the average closing bid price of
our common stock for the preceding month, except that the conversion price for
March 1998 was $0.15. Upon submission for conversion, we had the right to
redeem the preferred shares for 107.5% of the original purchase price. All
remaining shares of the Series F preferred stock were converted in 1998.

         During 1998, the Series F shareholders converted 1,081 shares of
Series F preferred stock into 5,571,503 shares of common stock. During 1997 the
Series F preferred stock shareholders converted 455 shares of Series F
Preferred stock into 714,746 shares of common stock and 164 shares of Series F
preferred stock were redeemed for $183,195 in cash.

Series G Preferred Stock

         From June 1997 through August 1997, through an exempt offering under
Regulation D of the Securities Act of 1933, we issued 1,700 shares of our
Series G preferred stock. The offering provided us with proceeds of $1,700,000.
There were no material expenses associated with this offering. Each share has a
liquidation preference of $1,000 plus 10% per annum from the date of issuance.
Each share of Series G preferred stock is convertible into shares of common
stock as determined by dividing the original issue price of the Series G
preferred stock, plus an accretion amount equal to 10 % of the issue price per
annum, by the conversion price. The conversion price is fixed at a rate of
$1.00 per share. The Series G preferred stock bears no dividends and holders of
the Series G preferred stock are entitled to vote on all matters submitted to a
vote of the stockholders on an "as if converted" basis.


                                    Page 13
<PAGE>   22
         In connection with the issuance of the Series G preferred shares, each
Series G shareholder also received warrants to purchase our common stock. The
number of warrants received by each shareholder was equal to 50% of the dollar
value of Series G preferred stock received. A total of 850,000 warrants were
issued in connection with this transaction. These warrants allow the holder to
purchase shares of our common stock of at a price of $1.00 per share for a
period of 10 years. The registration statement covering shares of common stock
into which the Series G preferred stock is convertible and the common stock
issuable upon exercise of the warrants was declared effective on June 18, 1998
and updated by amendment on June 23, 1999 and November 23, 1999.

         During 1999, a total of 500 shares of Series G preferred were
converted into 604,383 shares of common stock and in 1998, a total of 100
shares of Series G Preferred stock were converted into 110,000 shares of common
stock.

October 1997 Offering

         In October 1997, we closed an exempt offering under Regulation D of
the Securities Act of 1933. Under the terms of the offering, the investors
committed to purchase $3.5 million dollars of our common stock in seven
installments of $500,000 each. The first installment was payable at closing and
the next six installments were due on the first business day of each month from
November 1997 through April 1998. The purchase price for the shares was 65% of
the average closing bid price of our common stock for the five trading days
immediately preceding the due date of the installment. In addition, the
subscription agreement stipulated that the investors were to receive one
warrant for each share of our common stock purchased. These warrants were
exercisable for a period of five years at an exercise price equal to 115% of
the average closing bid price of our common stock for the five trading days
immediately preceding the issuance date of the warrants. The warrants were to
be issued on the same date as the previously described installment due dates.

         We received cash proceeds of $1,000,000 in 1997 and issued 2,829,334
shares of our common stock in connection with the installments due under the
October 1997 Offering in October and November. We also issued 1,118,868 shares
of our common stock in connection with the installment due December 1, 1997;
however payment was not received for those shares. We also issued 2,829,334
warrants at a price of $0.625 and 1,118,868 warrants at a price of $0.791. In
January 1998, we agreed to terminate the subscription agreement with the
investors. As a result of this agreement, the investors agreed to return
318,868 of the shares received in December, to pay cash of $250,000, and return
all warrants received under the agreement. After termination of the
subscription agreement in January 1998, we had received a total of $1,249,960
in proceeds. There were no material expenses associated with this offering. A
registration statement covering the shares issued in connection with this
offering was filed and declared effective by post-effective amendment on
October 28, 1997.


December 1997 Notes

         In December 1997, we issued notes payable to shareholders of the
Company in the amount of $485,000. These notes were six-month notes bearing
interest at a rate of 15% and secured by the assets of DTO. These notes were
convertible into our common stock at the option of the lender. The conversion
price of our common stock for determining the number of shares to be issued
equal to 75% of the average closing bid price of our common stock for the five
trading days preceding the date of notification. $300,000 of these notes were
converted into shares of our common stock at the time of the sale of the DTO
assets. The remaining $185,000, which was payable to our Chief Executive
Officer, was repaid at the time of the sale of the DTO assets.

Other 1997 Shares

         During 1997, we issued 30,000 shares of the our common stock to an
advisor as payment for services rendered. Based on the market value of the
stock at the time of issuance, $39,375 was charged to expense in connection
with this transaction. In addition, we issued 239,275 shares of our common
stock in 1997 to various trade creditors as payment for amounts due totaling
$235,644. Theses shares were registered on a registration statement declared
effective on June 9, 1997.

MCC Settlement

         During 1998, we issued 500,000 shares of our common stock to MCC as
part of an agreement to settle and pay the remaining amount due under the
minimum royalty agreement described in Note 12 to the Consolidated Financial
Statements. Based on the market price of our stock at the time, these shares
were valued at $100,000. In 1997 we also issued 340,717 shares of our common
stock to MCC to pay the remaining balance due on a services agreement entered
into in the April 1995 amendment to the MCC agreement. The remaining principal
and interest due under the agreement at the time of issuance of the shares was
$201,810.

1998 Private Placements

         In 1998, we issued 3,915,895 shares of restricted common stock, and
received cash proceeds of $713,236, in connection with private placements of
our common stock in exempt offerings under Regulation D of the Securities Act
of 1933. The shares were issued at prices approximating the market price of the
stock at the time of the offerings. A registration statement covering these
shares was declared effective June 18, 1998 and updated on June 23, 1999 and
November 23, 1999.

1998 Notes

         During 1998, we issued a total of $1,005,000 of notes payable to
investors that were convertible into shares of our common stock at the option
of the lender, primarily at a rate of $0.25 per share, which approximated the
market price at the time the loans were made. A total of $200,000 of these
notes were converted into shares of our common stock in 1998 and the remaining
$805,000 were converted into shares of our common stock in February 1999. We
also issued notes payable totaling $260,000 which were not convertible into our
common stock. These notes were short-term notes bearing interest at a rate of
15% and secured by all of our assets. In addition, we issued $100,000 of 90 day
notes payable bearing interest at a rate of 15%, secured by all of our assets,
and were accompanied by warrants enabling the holders to purchase a total of
400,000 shares of our common stock at $0.25 per share, which approximated
market at the time of the loans.

1999 Notes

         In January and February 1999, we borrowed a total of $200,000 from a
shareholder for working capital purposes. These short-term loans bear interest
at a rate of 15%, are secured by all assets of the Company, and are convertible
into our common stock at rates ranging from $0.30 to $0.40 per share. These
conversion rates approximated the market price of our common stock at the times
the loans were arranged. These notes were converted into shares of Company's
common stock in February 1999. The Company also issued a total of 200,000
shares of its common stock, in an exempt offering under Regulation D of the
Securities act of 1933, for a total of $110,000 in February 1999.

2000 Private Placements

         In December 1999, the board of directors authorized the issuance of up
to 800,000 shares of the of our common stock to an investor in an exempt
offering under Regulation D of the Securities Act of 1933 at a price of $1.25
per share. The agreement called for investments in increments of $250,000 at
the option of the Company. Through March 14, 2000, we have received a total of
$750,000. The shares for the first two increments, totaling $500,000, were
priced at $1.25 per share, as called for in the agreement. As a result of the
increase in our stock price since the time of the original agreement, the
shares issued as a result of the third increment of $250,000 were priced at
$2.50 per share. We are obligated to register these shares by August 2000.

SBOA Acquisition

         In September 1999, we acquired substantially all of the assets
(including the right to use the name) and assumed certain liabilities of Sign
Builders of America, Inc. In connection with this transaction we issued 423,132
shares of our common stock, which were valued at $900,000 at the time of
issuance to the former owner of SBOA. We also issued a total of $250,000 of
notes payable to the same individual. These notes are convertible into our
common stock at his option at a rate of $2.127 per share. In February 2000,
$125,000 of principal and the related accrued interest were converted into
62,284 shares of our common stock.

         The principal source of our liquidity has been funds received from
exempt offerings of common and preferred stock. We may receive additional funds
from the exercise of warrants, although there is no assurance that such
warrants will be exercised. In the event that we need additional funds, we may
seek to sell additional debt or equity securities. We may seek to increase our
liquidity through bank borrowings or other financings. While we expect to be
able to easily obtain any funds needed for operations, there can be no
assurance that any of these financing alternatives can be arranged on
commercially acceptable terms. We believe that our success in reaching
profitability will be dependent upon the viability of our products and their
acceptance in the marketplace, and our ability to obtain additional debt or
equity financings in the future. Our independent auditors, Wallace Sanders &
Co., expressed uncertainty as to the ability of the Company to continue as a
going concern based on accumulated past losses from operations. See
"Independent Auditors' Report."

                                    OUTLOOK

         We anticipate that losses will continue in early 2000 as we continue
to fund the development of our CFE technology and begin installations of our
electronic billboard and related electronic display products. We expect the
magnitude of the losses, if they continue, to decrease. We expect to reach
break-even on a monthly operating basis by the end of 2000. There can be no
assurance that we will be profitable in the future. Full commercial development
of our technology and electronic billboard and related electronic display will
require additional funds that may not be available at terms acceptable to us.

         We developed a plan to allow ourselves to maintain operations until we
are able to sustain ourselves on our own revenue. However, at current spending
levels, existing resources (including commitments) are only available to allow
us to operate for a period of approximately six months from the date of this
report. Our plan is primarily dependent on raising funds through the licensing
of our technology and through additional debt and equity offerings. We are also
concentrating on raising revenue by seeking customers for our electronic
billboard product, which is currently under development. We believe that we
have the ability to continue to raise short term funding, if necessary, to
enable us to continue operations until our plan can be completed.

         This plan is based on current development plans, current operating
plans, the current regulatory environment, historical experience in the
development of electronic products and general economic conditions. Changes
could occur which would cause certain assumptions on which this plan is based
to be no longer valid. Our plan is primarily dependent on increasing revenues
and raising funds through additional debt and equity offerings. Although we do
not expect funding our operations to be a problem, if adequate funds are not
available from operations, or additional sources of financing, we may have to
eliminate, or reduce substantially, expenditures for research and development,
testing and production of its products, or obtain funds through arrangements
with other entities that may require us to relinquish rights to certain of its
technologies or products. Such results would materially and adversely affect
us.

                          INDEPENDENT AUDITORS' REPORT


To the Board of Directors and Shareholders of SI Diamond Technology, Inc. and
Subsidiaries:

We have audited the accompanying consolidated balance sheets of SI Diamond
Technology, Inc. and Subsidiaries (collectively, the "Company") as of December
31, 1999 and 1998, and the related consolidated statements of operations,
shareholders' equity (deficit) and cash flows for the years then ended. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform our audits 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 the 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, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of SI
Diamond Technology, Inc. and Subsidiaries as of December 31, 1999 and 1998, and
the consolidated 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
the Company will continue as a going concern. As described in Note 1 to the
consolidated financial statements, the Company has relied primarily on capital
raised through offerings of common stock, preferred stock, and convertible debt
securities to fund its operations, and had sustained only operating losses
prior to 1999. As a result, there is substantial uncertainty regarding the
Company's ability to continue as a going concern. The accompanying consolidated
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.   ORGANIZATION AND OPERATIONS:

     SI Diamond Technology, Inc. and its subsidiaries are engaged in the
development of products for applications using its proprietary field emission
technology, commercialization of electronic digitized sign technology, and the
construction and sale of all types of outdoor signage. The Company has
performed contract research and development of advanced scientific applications
for governmental customers. The Company is performing significant research and
development related to its Carbon-Based Field Emission ("CFE") technology.

     The Company completed its initial public offering in 1993. Through
February 2000, in a series of offerings, the Company has raised proceeds of
approximately $57.3 million, net of issuance costs (See Note 8). As indicated
in the accompanying consolidated statements of operations, the Company was
profitable in 1999. This was the Company's first year of profitable operations
since its initial public offering. Through December 31, 1998, the Company had
incurred cumulative losses of approximately $54.7 million. The increase in
revenue and corresponding profit increase in 1999 was primarily the result of a
$5.6 million license agreement signed with Canon, Inc. (Japan). As of the date
of this filing, the Company has the resources available to fund operations for
a period of approximately six months. The Company is seeking additional
licensees for its technology to fund ongoing operations.

     In addition, the Company is launching its electronic billboard product and
expects to begin receiving revenues from this product in March 2000. To the
extent that it is unable to raise sufficient funds through license agreements,
the Company may seek additional funds through the equity markets, or raise
funds through debt instruments to allow it to maintain operations until it is
able to sustain itself on its own revenue. There is no assurance that license
agreements will be signed, that funds will be available in the equity or debt
markets, or that commercialization will result in income from operations.
Management believes it will be able to secure additional short term funding, if
need be, to allow the Company to continue operations until an agreement can be
finalized to license its technology or additional debt or equity can be raised.
Full commercial development of the Company's CFE technology may require
additional funds that may not be available at terms acceptable to the Company.

     The principal source of the Company's liquidity has been from the funds
received from exempt offerings of common stock, preferred stock, and
convertible debt securities. The Company may receive additional funds from the
exercise of warrants or options, although there is no assurance that
significant funds will be received from the exercise of any such warrants or
options in the near future. The Company may also seek to increase its liquidity
through additional bank borrowings or other financings. There can be no
assurance that any of these financing alternatives can be arranged on
commercially acceptable terms. The Company believes that its success in
reaching profitability will depend on the viability of its products and
technology, their acceptance in the marketplace, and its ability to obtain
additional debt or equity financings in the future.

     A portion of the Company's research and development has been funded
through the sponsorship of agencies of the U.S. Government. The Company
currently has only one minor funded research project from the U.S. Government
and will only seek additional grants to the extent they directly relate to the
Company's core technology. Under the present circumstances, the majority of
research and development performed is being internally funded by the Company.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of consolidation

     The accompanying consolidated financial statements include the accounts of
the Company and its subsidiaries, Field Emission Picture Element Technology,
Inc. ("FEPET"), Electronic Billboard Technology, Inc. ("EBT"), Sign Builders of
America, Inc. ("SBOA"), Diamond Tech One, Inc. ("DTO"), SDI Acquisition Corp.
("SDI"), and Plasmatron Coatings and Systems, Inc. ("Plasmatron"), after the
elimination of all significant intercompany accounts and transactions. FEPET is
primarily involved in developing products for applications using the Company's
proprietary CFE technology. EBT is primarily involved in the commercialization
of electronic digitized sign technology. SBOA is a manufacturer of custom
signage. The Companies remaining subsidiaries (SDI, DTO, and Plasmatron,) are
currently inactive.


Contract revenues and technology rights

     A portion of the Company's revenues have consisted of earnings under
agreements to perform research and development for others, primarily U.S.
federal government agencies. The agreements with federal government agencies
generally provide that, upon completion of a technology development program,
the funding agency is granted a royalty-free license to use the newly developed
technology for its own purposes. The Company retains all other rights to use,
develop, and commercialize the technology.

Revenue recognition

     The Company recognizes revenue from the construction and sale of custom
signage when the sign is installed on the customer's premises. The Company
recognizes royalty revenue at the time the underlying product upon which the
royalty is based is shipped by the entity paying the royalty. License revenue
from licensing the Company's product is recognized as revenue when received.

Cash and cash equivalents

     The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

Marketable securities

     The Company invests in equity securities of publicly traded corporations
on a temporary, or short term, basis. These securities are purchased with the
intent of selling them for a profit in the near term and to achieve higher
returns on capital available for temporary investment than are otherwise
available in the debt market. These securities are carried on the consolidated
balance sheet at fair market value.

Accounts receivable

     The Company sells products and services on credit primarily to large U.S.
based corporations and governmental agencies, although in some instances it may
ship products to Asia or Europe. The Company's SBOA subsidiary frequently sells
to smaller companies, but requires deposits and prepayments. It is the
Company's policy to record reserves for potential credit losses. Since
inception, the Company has experienced minimal losses. The Company had a
reserve for potential credit losses of approximately $6,000 at December 31,
1999 and no reserve at December 31, 1998.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

Inventories

     Inventories are recorded at the lower of cost (first-in, first-out) or
market. Inventories consist of purchased components and work-in-process at
December 31, 1999 and entirely of purchased components at December 31, 1998.


Property, plant and equipment

     Property, plant and equipment are recorded at cost, net of accumulated
depreciation and amortization. Depreciation is provided on the straight-line
method over the estimated useful lives of the assets, which range from two to
seven years, or the lease term for leasehold improvements, if less.
Expenditures for major renewals and betterments that extend the original
estimated economic useful lives of the applicable assets are capitalized.
Expenditures for normal repairs and maintenance are charged to operations as
incurred. The cost and related accumulated depreciation or amortization of
assets sold or otherwise disposed of are removed from the accounts, and any
gain or loss is included in income.

Intangible assets

     The Company has applied to obtain certain United States patents, which are
currently pending. Certain patent costs, which consist primarily of legal fees,
have been capitalized and are being amortized using the straight-line method
over the useful lives of the patents (5 years), if approved. If such patents
are rejected, the costs will be charged to expense at the date of rejection.
The Company wrote off the costs associated with certain patents no longer
expected to have value to the Company as well as related liabilities. This
write off had no material impact on expense in either 1999 or 1998. The
majority of patent costs are expensed as incurred.

     In connection with the acquisition of the assets of SBOA in August 1999,
the former owner of SBOA entered into a covenant not to compete with the
Company, whereby this individual agreed not to compete with the Company for a
period of three years from the date of the acquisition. This covenant not to
compete is being amortized over the three year period covered by the agreement.
The Company also recorded goodwill in connection with the SBOA transaction.
This goodwill is being amortized over a 15 year period.

     At each balance sheet date, the Company evaluates the carrying amount and
the amortization period for its intangible assets. If an indicator of
impairment is present, the Company compares the projected undiscounted
operating cash flows for the related business with the unamortized balance of
the related intangible asset. If an imminent loss exists, management estimates
the fair value of the intangible asset based on future operating cash flows for
the next ten years, discounted at the Company's borrowing rate. The excess of
the unamortized balance of the intangible asset over the fair value is charged
to impairment loss.

Income taxes

     The Company accounts for income taxes using the liability method pursuant
to Statement of Financial Accounting Standards ("SFAS") No. 109. Under this
method, deferred income taxes are recorded to reflect the tax consequences on
future years of temporary differences between the tax basis of the assets and
liabilities and their financial amounts at year-end. The Company provides a
valuation allowance to reduce deferred tax assets to their net realizable
value.

Research and development expenses

     Costs of research and development for Company-sponsored projects are
expensed as incurred.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

Minority Interest in Subsidiary

     The minority interest in subsidiary represents the 5% of FEPET owned by
Diamond Pro-Shop Nomura, Company, Ltd. and is equal to 5% of the book value of
FEPET.


Preferred stock dividends

     The Series E and F preferred stocks contained a provision (See Note 8)
that allowed the preferred shareholder to convert their preferred shares to
common stock at a discount to the market value of the stock. The amount of this
discount was treated as a dividend to the preferred shareholders. In addition,
the Series E preferred stock included an 8% accretion payable in common stock
and the Series F preferred stock included a 4% accretion payable in common
stock, payable at the date of conversion at the same price as the common shares
being received. The Company's Series G Preferred stock bears a 10% accretion
payable in common stock at the date of conversion. All accretions paid in
common stock or payable in common stock if the shares had been converted as of
December 31, 1999 and 1998, respectively, have been treated as preferred
dividends. The amount treated as a dividend in 1999 related to the accretion
was $140,163, all related to the Series G preferred stock. The amount treated
as a dividend in 1998 related to the accretion and the discount was $36,142,
$53,815, and $165,000, respectively for the Series E, Series F, and Series G
preferred stocks.


Income (loss) per common share

     In 1997, the Company adopted SFAS No. 128 "Earnings Per Share" which
requires the Company to present its basic income (loss) per share and diluted
income (loss) per share, and certain other income (loss) per share disclosures
for each year presented. Basic income (loss) per share is computed by dividing
income (loss) available to common shareholders by the weighted-average number
of common shares outstanding. The computation of diluted income (loss) per
share is similar to the computation of basic income (loss) per share except
that the denominator is increased to include the number of additional common
shares that would have been outstanding if the dilutive potential common shares
had been issued. In addition, the numerator is adjusted for any changes in
income or loss that would result from the assumed conversions of those
potential shares.

In 1998 the Company had various amounts of preferred shares, common stock
options and warrants outstanding during the years which were not included in
the diluted loss per share calculation because they would have been
antidilutive. As of December 31, 1998, the Company had 1,700 preferred shares
outstanding, 4,227,397 options outstanding, and 2,695,379 warrants outstanding.

Reclassifications

     Certain reclassifications were made to previously reported amounts in the
accompanying consolidated financial statements and notes to make them
consistent with the current year presentation format.

Management's estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities, revenues,
and expenses, as well as the disclosure of contingent assets and liabilities.
Actual results could differ from those estimates.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

Fair value of financial instruments

     The Company's financial instruments as defined by SFAS No. 107,
"Disclosures about Fair Value of Financial Instruments," include cash and cash
equivalents, marketable securities, accounts receivable, notes receivable,
accounts payable, accrued liabilities, notes payable, and capital lease
obligations. All financial instruments, except for marketable securities, are
accounted for on an historical cost basis, which approximates fair value at
December 31, 1999 and 1998.

Comprehensive Income

     In 1998, the Company adopted Statement of Financial Accounting Standards
No. 130 "Reporting Comprehensive Income", which establishes standards for
reporting and displaying comprehensive income and its components in a full set
of general purpose financial statements. Comprehensive income (loss)
approximates the net income (loss) reported for both years.

3.   MARKETABLE SECURITIES

     The Company invested a portion of its working capital in marketable equity
securities. All such equity securities were classified as trading securities.
At December 31, 1999, the Company had securities with a cost basis of $540,646,
unrealized gains of $178,730, and a fair market value of $719,376. During 1999,
the Company realized proceeds from the sale of securities of $1,533,318 and
recognized gains of $210,197, losses of $79,755, and a net gain of $130,442. In
total, the Company recognized $309,172 of net realized and unrealized gains in
the income statement for the year ended December 31, 1999. The Company had no
marketable equity securities at December 31, 1998 and no activity with
marketable equity securities in 1998.

credit carryforwards related to research and development expenditures of
approximately $478,000 that expire through 2011 and foreign tax credits of

have effected ownership changes under Internal Revenue Code Section 382. The
IPO and subsequent stock issuances may limit the Company's ability to utilize
its net operating loss carryforwards and research and experimentation credits
generated before the changes in ownership.

Series A

     The Company had 100 shares of its Series A convertible preferred stock
issued and outstanding as of December 31, 1998. The Series A preferred shares
were converted into 125,275 shares of the Company's common stock during 1999.
While it was outstanding, the Series A preferred stock was noncumulative. It
had a liquidation preference of $1,000 per share, was convertible into 1,252.75
shares of common stock per share and was entitled to vote on all matters
submitted to a vote of the shareholders on an "as if converted" basis. In
December 1999, the Company amended its articles of incorporation to eliminate
the Series A preferred stock.

Series C

     There are currently no outstanding shares of the Series C preferred stock;
however, 75,000 shares were authorized for issuance pursuant to outstanding
Series C warrants. These warrants to purchase Series C preferred stock expired
on February 9, 1998. In December 1999, the Company amended its articles of
incorporation to eliminate the Series C preferred stock.

Series E

     In December 1995 and January 1996 through an exempt offering under
Regulation D of the Securities Act of 1933, the Company received subscriptions
for and issued 1,190 shares of its Series E convertible preferred stock. The
offering provided proceeds of approximately $11,900,000 to the Company, less
offering expenses of approximately $1,631,000. The Series E preferred stock was
noncumulative and had a liquidation preference of $10,000 per share plus 8% per
annum from the date of issuance, and was entitled to vote on all matters
submitted to a vote of the shareholders on an "as if converted" basis.

     Each share of Series E preferred stock was convertible into that number of
shares of common stock determined by dividing the original issue price of the
Series E preferred stock, plus an accretion amount equal to 8% of the issue
price per annum, by the conversion price. The conversion price was the lesser
of $1.50 or the average closing bid price for the Company's common stock for
the calendar month immediately preceding the conversion date. The amount
convertible in any calendar month at a price equal to the average closing bid
price for the Company's common stock for the calendar month immediately
preceding the conversion date was limited to 7% of the shares held by the
Series E shareholder as of April 14, 1997. The preferred shares could be
redeemed for cash, at the option of the Company, upon presentation of the
shares for conversion.

stock were redeemed for cash of $332,011. As of December 31, 1998, all shares

issued as a result of the conversion of 1,128 shares of the Series E Preferred
Stock. In December 1999, the Company amended its articles of incorporation to
eliminate the Series E preferred stock.


Series F

     In March 1997, the Company closed an exempt offering under Regulation D of
the Securities Act of 1933 for 1,700 shares of its Series F convertible
preferred stock. The Company received net proceeds of $1,527,500, which
represented gross proceeds of $1,700,000 less offering expenses of $172,500.
Each share had a liquidation preference of $1,000 plus 4% per annum from the
date of issuance. Each share of Series F preferred was convertible into that
number of shares of common stock determined by dividing the original issue
price of the Series F preferred stock, plus an accretion amount equal to 4 % of
the issue price per annum, by the conversion price. The conversion price was
the lesser of $1.75 or 80% of the 10 day average closing bid price prior to the
conversion date. The Series F preferred stock bore no dividends and holders of
the Series F preferred stock had no voting power except in certain
circumstances pursuant to Texas state law.

     On March 17, 1998, the Company revised its Amended and Restated Articles
of Incorporation pursuant to an agreement with the Series F preferred stock
shareholders. Under the terms of this agreement, the Series F preferred stock
shareholders were allowed to convert one-sixth of the number of Series F
preferred shares held as of March 17, 1998 in each of the months from March
1998 through August 1998 into the Company's common stock. The conversion price
for each month was the average closing bid price of the Company's common stock
for the preceding month, except that the conversion price for March 1998 was
$0.15. Upon submission for conversion, the Company had the right to redeem the
preferred shares for 107.5% of the original purchase price. All remaining
shares of the Series F preferred stock were converted in 1998.

     During 1998, the Series F preferred stock shareholders converted 1,081
shares of Series F preferred stock into 5,571,503 shares of common stock.
Cumulatively, 1,536 shares of the Series F preferred stock were converted into

its Series G preferred stock. The offering provided gross proceeds of

8.   CAPITAL STOCK (CONTINUED):

     Each share of Series G preferred stock is convertible into that number of
shares of common stock determined by dividing the original issue price of the
Series G preferred stock, plus an accretion amount equal to 10 % of the issue
price per annum, by the conversion price. The conversion price is fixed at a
rate of $1.00 per share.

     In connection with the issuance of the Series G preferred shares, each
Series G shareholder also received warrants to purchase the Company's common
stock. The number of warrants received by each shareholder was equal to 50% of
the dollar value of Series G preferred stock received. A total of 850,000
warrants were issued in connection with this transaction. These warrants allow
the holder to purchase shares of the Company's common stock of at a price of
$1.00 per share for a period of 10 years. The registration statement covering
shares of common stock into which the Series G preferred stock is convertible
and the common stock issuable upon exercise of the warrants was declared

     During 1999, 500 shares of Series G preferred stock were converted into
604,383 shares of the Company's commons stock. During 1998, 100 shares of
Series G preferred stock were converted into 110,000 shares of common stock.

Subsidiary Preferred Stock

     In September 1997, the Company completed an agreement with Diamond
Pro-shop Nomura Co., Ltd. ("DPN"), an affiliate of Noritake. Both DPN and
Noritake are corporations organized under the laws of Japan. Under the terms of
the agreement, DPN acquired 50 shares of convertible preferred stock and
acquired certain licensing and marketing rights for products developed by FEPET
in exchange for a payment of $500,000. Of this payment, $400,000 was allocated
to the licensing and marketing rights and $100,000 was allocated to the
preferred stock based on its estimated fair market value at that date. These
preferred shares convert FEPET common shares equivalent to a 5% ownership
interest in FEPET. In January 2000, DPN transferred its ownership of these
shares to Nomura Holding Company, an affiliate of DPN. In February 2000, the
Company agreed to exchange Nomura's FEPET shares for 200,000 shares of the
Company's common stock.

Common Stock

     In October 1997, the Company closed an exempt offering under Regulation D
of the Securities Act of 1933 (the "October 1997 Offering"). Under the terms of
the offering, the investors committed to purchase $3.5 million dollars of the
Company's common stock in seven installments of $500,000 each. The first
installment was payable at closing and the next six installments were due on
the first business day of each month from November 1997 through April 1998. The
purchase price for the shares was 65% of the average closing bid price of the
Company's common stock for the five trading days immediately preceding the due
date of the installment. In addition, the subscription agreement stipulated
that the investors were to receive one warrant for each share of the Company's
common stock purchased. These warrants were exercisable for a period of five
years at an exercise price equal to 115% of the average closing bid price of
the Company's common stock for the five trading days immediately preceding the
issuance date of the warrants, with the warrants to be issued on the same date
as the previously described installment due dates.

     The Company issued 1,118,868 shares of its common stock in connection with
the installment due December 1, 1997; however payment was not received for
those shares. In January 1998, the Company and the investors agreed to
terminate the subscription agreement. As a result of this agreement, the
investors agreed to return 318,868 of the shares received in December, pay cash
of $250,000, and return all warrants received under the agreement. After
termination of the subscription agreement in January 1998, the Company had
received a total of $1,250,000 in proceeds. There were no material expenses
associated with this offering. A registration statement covering the shares
issued in connection with the October 1997 Offering was filed and declared
effective by post-effective amendment on October 28, 1997.

     During 1999, $1,005,000 of the convertible notes, including accrued
interest, were converted into 4,040,275 shares of the Company's common stock.
Of the notes converted, $805,000 of these notes were outstanding at December
31, 1998 and $200,000 of the notes were issued in 1999. The notes were
converted at rates ranging from $0.25 to $0.40 per share and were based on the
price of a common share at the time the notes were issued. Of the notes
outstanding at December 31, 1998 that were converted in 1999, $100,000 were
payable to the Company's Chief Executive Officer. These notes resulted from the
CEO's personal guarantee of a loan made by an investor. The loan was made to
the CEO, who in turn loaned the money to the Company under the same terms. In
April 1999, these notes payable were assigned by the CEO to the holder of the
underlying note payable. A registration statement covering all shares issued as
a result of convertible notes was declared effective June 23, 1999.

     In 1999, the Company issued 200,000 shares of restricted common stock and
received cash proceeds of $100,000 in connection with private placements of the
Company's common stock in exempt offerings under Regulation D of the Securities
act of 1933. The shares were issued at prices approximating the market price of
the stock at the time of the offerings. A registration statement covering these
shares was declared effective June 23, 1999.

and received cash proceeds of $713,236 in connection with private placements of
the Company's common stock in exempt offerings under Regulation D of the
Securities act of 1933. The shares were issued at prices approximating the
market price of the stock at the time of the offerings. A registration
statement covering these shares was declared effective June 18, 1998.

     In 1998, the Company issued 500,000 shares of common stock to MCC in
connection with the minimum royalty payment also described in Note 12.

9.   STOCK OPTIONS:

     The Company sponsors three stock-based incentive compensation plans (the
"Plans"). The Company applies Accounting Principles Board ("APB") Opinion No.
25 and related interpretations in accounting for the Plans. In 1995, the FASB
issued SFAS No. 123 "Accounting for Stock-Based Compensation" which, if fully
adopted by the Company, would change the methods the Company applies in
recognizing the cost of the Plans. Adoption of the cost recognition provisions
of SFAS No. 123 is optional and the Company has decided not to elect these
provisions of SFAS No. 123. However, pro forma disclosures as if the Company
adopted the cost recognition provisions of SFAS No. 123 are required by SFAS
No. 123 and are presented below.

     In March 1992, the shareholders of the Company approved the 1992 Employees
Stock Option Plan (the "1992 Employees Plan") for purposes of granting
incentive or non-qualified stock options. The 1992 Employees Plan was amended
in July 1996 by the shareholders of the Company to reserve up to 3,000,000
shares of common stock for issuance to certain officers and key employees. The
Company's Board of Directors amended the plan in January 1999 to increase the
number of shares authorized under the plan to 3,500,000 and further amended the
plan in December 1999 to increase the number of shares authorized under the
plan to 6,500,000.

9.   STOCK OPTIONS (CONTINUED):

     The incentive stock options are exercisable for up to ten years, at an
option price per share not less than the fair market value on the date the
option is granted. The incentive stock options are limited to persons who have
been regular full-time employees of the Company or its present and future
subsidiaries for more than one (1) year and at the date of the grant of any
option are in the employ of the Company or its present and future subsidiaries.
Non-qualified options may be granted to any person, including, but not limited
to, employees, independent agents, consultants and attorneys, who the Company's
Compensation Committee believes have contributed, or will contribute, to the
success of the Company. Non-qualified options may be issued at option prices of
less than fair market value on the date of grant and are exercisable for up to
ten years from date of grant. The option vesting schedule for options granted
is determined by the Compensation Committee of the Board of Directors at the
time of the grant. At December 31, 1999, 3,180,940 shares remained available
for grant under the 1992 Employees Plan.

     In March 1998 and May 1998, the Company's Board of Directors passed
resolutions that reduced the option exercise price of certain options
previously granted under the 1992 Employees Plan. A total of 1,727,750 options
were repriced. The Company reduced the exercise price to $0.375 for all options
priced above that level for all persons employed by the Company at the time of
the repricing. The original exercise price of these options ranged from $1.125
to $4.00. The market price of the Company's common stock at the time of the
March and May repricings was $0.14 and $0.25 per share, or approximately 63%
and 33%, respectively, below the new exercise price.

     The fair value of each stock option granted in 1999 and 1998 is estimated
on the date of grant using the Black-Scholes option pricing-model with the
following weighted-average assumptions: no dividend yield for 1999 and 1996;
risk-free interest rate of 5.50% and 5.00% for 1999 and 1998, respectively; the
expected lives of the options are five years for 1999 and 1998; and volatility
of approximately 100% for both 1999 and 1998.

12.  COMMITMENTS AND CONTINGENCIES:

Agreements with MCC

     The Company entered into an agreement in 1994 with Microelectronics and
Computer Technology Corporation ("MCC") that was amended on several subsequent
occasions to cross license and pool technologies. As part of this relationship
with MCC, the Company acquired non-exclusive licenses to 144 MCC patents and
other related technology. Under the license, the Company was obligated to pay
MCC a cumulative minimum royalty of $500,000 by December 31, 1997 and
$1,000,000 by December 31, 1998. As a result of amendments signed in December
1997 and September 1998, 62 Diamond Field Emission patents were assigned
directly to the Company and 82 patents were returned to MCC. The Company agreed
to pay a royalty fee of 2% of future commercial revenues related to the patents
assigned to it. The Company has the right to offset one half of the costs of
maintaining these patents against any royalties due under the agreement. MCC
agreed to accept a cash payment of $5,000 and 500,000 shares of the Company's
common stock in exchange for releasing the Company from the minimum royalty
agreement. As of December 31, 1997 the Company had accrued $355,000 due under
the minimum royalty agreement. The stock issued in connection with this
agreement was valued at $100,000 based on the market price at the time. The
remaining $250,000 was taken into income 1998.

DiaGasCrown Venture

In February 1995, the Company entered into an agreement with Diagascrown, Inc.,
a Russian joint stock company controlled by Gazcomplektimpex, a subsidiary of
Gazprom, the Russian national natural gas company. In return for an equity
position in the Company, DGC paid the Company $5,000,000 and granted the
Company an exclusive license to DGC display and related diamond technology and
license rights to all related background patents. The Company has committed to
perform $2.5 million in research and development in Russia. There is
disagreement as to the amount actually spent, however it is our position that
there are no further amounts due under this agreement and there will be no
further spending in Russia. The internal results that we have achieved are far
superior to those achieved through the collaborative efforts in Russia and at
present we are not using the technology developed under this joint venture
agreement in any manner.

12.  COMMITMENTS AND CONTINGENCIES (CONTINUED):

Legal Proceedings

     On May 20, 1996, Semi-Alloys Company, a former customer of Plasmatron,
filed a complaint with the Supreme Court of the State of New York, County of
Westchester. The complaint names Plasmatron, the Company and Westchester Fire
Insurance Company as defendants. Semi-Alloys claims a breach of contract related
to $1 million of coating equipment that Plasmatron delivered in 1993, prior to
the Company's ownership of Plasmatron. Semi-Alloys claims the equipment does not
perform as required under the contract. Semi-Alloys seeks to recover
compensatory, consequential and incidental damages. In January 2000, the Company
agreed to participate in a settlement agreement between the plaintiff and the
other defendant; notwithstanding our denial of any liability to the plaintiff.
The Company agreed to pay a total of $450,000, of which $225,000 was due at
signing. The Company signed three notes payable for the balance of the
settlement. These notes, in the amount of $25,000, $100,000, and $100,000, are
due in three months, nine months, and eighteen months, respectively and bear
interest at a rate of 10% per annum. In exchange for this settlement, and upon
payment of the notes, the Company will receive a complete release from further
liability from both the plaintiff and the co-defendant. The entire amount of
this settlement is included in accrued liabilities at December 31, 1999.

     On April 30, 1998, Universal Bonding Company, managing general agent for
Westchester Fire Insurance Company filed a complaint with the Superior Court of
New Jersey, Atlantic county. The Complaint named Richland Glass Company, Inc.,
Robert Williams, Joan Williams, Bawa Singh, Narinder Singh, Gaylord Evey and
Doris Evey, all guarantors under the bond, as defendants. All defendants were
former owners, or associated with former owners, of Plasmatron. Defendant
Gaylord Evey filed an answer with the court naming Plasmatron, the Company,
Nicholas Rettino, and the Rettino Insurance agency as third party defendants and
asking for indemnification by the third party defendants. A separate
indemnification claim filed by Richland Glass against the same third party
defendants was consolidated with this case. The amount of this claim is to be
determined at trial; however, any potential amounts due by the Company are
dependent upon Westchester collecting from other guarantors on the bond, and
those guarantors succeeding in obtaining a judgement against the Company.
Westchester has released its claims against the Company. The Company considers
this case to be without merit and expects to have the case ultimately resolved
in its favor.

     On July 20, 1998, TFI Telemark, Inc., a former vendor of Plasmatron, filed
a complaint in the County Court at Law No. 2 of Travis County, Texas against the
Company for debts of its subsidiary, Plasmatron. The Company was served with
notice of this suit on August 5, 1998. All amounts claimed as owing by TFI are
recorded as liabilities of Plasmatron in the consolidated financial statements
of the Company. The Company believes the ultimate resolution of this matter will
not have a material impact on the consolidated financial statements of the
Company.

     On January 28, 1999, Aetna Life Insurance Company, a former landlord of
DTO, filed a complaint in the 126th Judicial District Court, Travis County,
Texas against DTO as lessee, and the Company as guarantor, for unspecified
alleged damages occurring as a result of DTO's early termination of a lease. DTO
moved out of this facility with approximately nine months remaining on the lease
which called for monthly rental payments of approximately $17,000. The Company
contends that Aetna failed in its duty to mitigate damages and behaved in a
reckless manner, which resulted in damages to the Company and its property. The
Company intends to vigorously defend itself in this action. The Company believes
that the ultimate resolution of this matter will not have a material impact on
the consolidated financial statements of the Company.

     The Company and its subsidiaries are also defendants in other lawsuits of a
non-material nature related to the non-payment of invoices when due. It is
expected that all such lawsuits will be settled for an amount no greater than
the liability recorded in the financial statements for such matters and that
settlement of such suits will not have a material financial impact on the
Company.

Vision Mark Agreement

     In November 1998, the Company signed a marketing agreement with Vision
Mark, LLC ("Vision Mark"), a Texas limited liability company and a related
consulting and advisory services agreement with C&A Services LLC ("C&A"), a
Texas limited liability company affiliated with Vision Mark., whereby Vision
Mark and C&A agreed to represent the Company with several "protected" customers,
as defined by the agreements. Under the terms of the agreements, the Company is
obligated to provide C&A with 300,000 shares of its common stock upon the
signing of an agreement with any one of the protected customers to provide an
electronic billboard to such customer. In January 2000, the Company signed an
agreement with Eckerd Corporation, a subsidiary of JCPenney, Inc., one of the
protected customers. Accordingly, 300,000 shares of common stock were issued to
C&A as a result of this agreement. In addition, C&A received warrants to
purchase up to 9,700,000 shares of the Company's common stock.

     The warrants granted to C&A become exercisable under the following
conditions:

1.   At such time as the Company receives total revenue of $10 million from any
     or all of C&A's protected customers, C&A has the right to purchase 250,000
     shares of common stock of the Company at a discounted price per share equal
     to 50% of the market price of the stock at the time the $10 million
     milestone is achieved.

2.   Thereafter, for each increment of $10 million of revenue received from
     protected customers, C&A has the right to purchase another 250,000 shares
     at a discounted price per share equal to 50% of the market price of the
     stock at the time each $10 million increment is achieved.

3.   In addition, when the total revenue received from any or all of C&A's
     protected customers reaches $100 million, C&A has the right to acquire an
     additional 2.3 million shares of the common stock of the Company at a
     discounted price per share equal to 50% of the market price of the stock at
     the time $100 million in revenue is achieved.

4.   An additional 2.3 million shares of the Company's common stock will be made
     available to C&A at a discounted price equal to 50% of the market price of
     the stock at the time cumulative revenues from protected customers reaches
     $200 million.

5.   Finally, at the end of each twelve month period (ending on the anniversary
     date of the agreement) in which the revenue from protected customers
     exceeds $10 million during that period, C&A has the right to acquire up to
     200,000 shares of common stock of the Company under the following terms and
     conditions;

a.   If the revenue received from protected customers equals or exceeds 25% of
     the total Company revenue for that twelve month period, then C&A may
     purchase 100,000 shares of the Company's common stock at a discounted price
     which is equal to 75% of the market price of the common stock at the end of
     the period.

b.   C&A may acquire the remaining 100,000 shares at a reduced price where the
     discount from the market price is equal to the ratio (expressed as a
     percentage) that the revenue from C&A protected customers bears to the
     total Company revenue received during that period. The maximum discount can
     not exceed 50%.

6.   The maximum number of shares that can be acquired pursuant to these
     warrants is 9.7 million and all warrants issued under this agreement expire
     December 31, 2006.

Government contracts

     Governmental contractors are subject to many levels of audit and
investigation. Among United States agencies that oversee contract performance
are: the Defense Contract Audit Agency, the Inspector General, the Defense
Criminal Investigative Service, the General Accounting Office, the Department of
Commerce, the Department of Justice and Congressional Committees. The Company's
management believes that an audit or investigation, if any, as a result of such
oversight would not have any material adverse effect upon the Company's
financial condition or results of operations.

13.  CONCENTRATIONS OF CREDIT RISK:

     The Company's financial instruments that are exposed to concentrations of
credit risk consist of cash and cash equivalents and receivables. The Company
places its cash and cash equivalents with high credit quality financial
institutions. At December 31, 1999 and 1998, the Company had no amounts on
deposit in excess of the Federal Deposit Insurance Corporation insurance limit;
however, for limited periods of time during the year, bank balances may exceed
such limits.

     The Company's receivables are uncollateralized and result primarily from
its research and development projects performed primarily for U.S. Federal
Government Agencies and services performed for large U.S. and multinational
corporations. The Company's SBOA subsidiary also provides services for small and
medium size companies, but requires deposits and progress payments for work
performed. The Company has not incurred any material losses on these
receivables.

14.  SEGMENT INFORMATION:

     The Company had no revenues from government contracts in 1999 or 1998 The
majority of the government contracts are cost reimbursement contracts. As a
result, the Company realizes little or no gain or loss in the performance of
these contracts. The Company's contracts involving the United States government
are or may be subject to various risks, including unilateral termination for the
convenience of the government. As of December 31, 1999, the Company had a
commitment for future government funding of approximately $67,000.

15.  RELATED PARTY TRANSACTIONS:

     As described in Notes 6 and 8, the Company had notes payable to its Chief
Executive Officer at December 31, 1998.

     In October 1998, Electronic Billboard Technology, Inc., a subsidiary of the
Company entered into a Patent Assignment and Royalty Agreement with Advanced
Technology Incubator, Inc., ("ATI") a corporation based in Austin, Texas and
owned by Dr. Zvi Yaniv, the Company's President and Chief Operating Officer.
Under the terms of the agreement, ATI agreed to assign U.S. Patent No. 5,469,187
related to certain LCD technology to EBT in exchange for an initial payment of
$200,000. In addition, ATI is entitled to receive a royalty of 5% of gross
revenue related to products using this patent. EBT intends to use this
technology in the development of its next generation electronic billboard
product. EBT may terminate this assignment at any time upon 30 days written
notice to ATI. The assignment may be terminated by ATI if, within two years of
the first sale or lease of a billboard using this technology, cumulative royalty
payments under the agreement have not totaled $500,000, or if payments do not
equal $500,000 in any one year period following this initial two year period. If
the assignment is terminated by ATI, EBT will be granted a non-exclusive
worldwide license to use the technology under terms similar to those contained
in this agreement.

     ATI had the right to terminate this agreement if the initial payment was
not received by February 15, 1999. This date was extended until April 15, 1999.
In April 1999, the agreement was amended to allow additional extensions, in
three month increments, for a period of up to one year from April 15, 1999. In
exchange for each three month extension, the Company was obligated to pay ATI
$12,500. The $200,000 initial payment required for the actual assignment of the
Patent under the agreement will be reduced for any amounts paid for the
extension periods. The Company elected to exercise each of its extension options
and paid ATI a total of $50,000 through January 2000. In April 2000, unless the
contract is renegotiated, the Company must pay $150,000 to complete the
assignment of the patent, or allow its option to acquire the patent to lapse.

16. ACQUISITION OF SIGN BUILDERS OF AMERICA, INC.:

     Effective August 31, 1999, the Company purchased substantially all of the
assets and assumed certain liabilities of Sign Builders. The assets acquired and
liabilities assumed were recorded at fair values as a purchase acquisition and
have been accounted for as a non-cash transaction in the consolidated statement
of cash flows. The Company used cash of $450,000, executed a note payable
bearing interest at an annual rate of 6% in the amount of $250,000, and issued
common stock valued at $900,000 to finance the transaction. The assets acquired
and liabilities assumed are as follows:

                                                       ==========
</TABLE>

The cash paid of $450,000 is reflected in the consolidated statement of cash
flows net of the $24,089 of cash received in connection with the acquisition of
the assets. The purchase agreement contained certain contingencies related to
the sales of the acquired business during the time period from September 1, 1999
through December 31, 1999 which resulted in downward adjustments to the purchase
price. As a result of these adjustments, the original purchase price of
$1,800,000 was adjusted downward to the $1,600,000 reflected above. The notes
payable described above were adjusted down to their final amount of $250,000
from their initial amount of $450,000 as a result of the same purchase price
adjustments.

The following unaudited pro forma data summarize the results of operations for
the Company for the periods indicated as if the Sign Builders acquisition had
been completed as of the beginning of the periods presented. The pro forma data
give effect to actual operating results prior to the acquisition and adjustments
to interest expense, goodwill amortization and income taxes. No effect has been
given to cost reductions or synergies in this presentation. These pro forma
amounts do not purport to be indicative of the results that would have actually
been obtained if the acquisition had occurred as of the beginning of the periods
presented or that may be obtained in the future.

             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities of Exchange Act of 1934 requires SI
Diamond's officers, and Directors, and persons who beneficially own more than 10
% of a registered class of SI Diamond's common stock, to file reports of
ownership and changes in ownership with the Securities and Exchange Commission
and NASDAQ. Officers, Directors, and beneficial owners of more than 10% of SI
Diamond's common stock are required by the Securities and Exchange Commission
regulations to furnish SI Diamond with copies of all Section 16(a) forms that
they file.

Based solely on review of the copies of such reports furnished to us, or written
representations that no reports were required, we believe that for the period
from January 1, 1999 through December 31, 1999, all its Officers, Directors, and
greater than 10% beneficial owners complied with all Section 16(a) filing
requirements applicable to them, with the exception of one Director, Charles C.
Bailey. Mr. Bailey filed his initial Form 3, which reported ownership as of the
date Mr. Bailey became a director, after the due date of the form.

table. They do not receive compensation as Directors. Refer to the Summary
Compensation Table for information concerning their compensation. Mr. Arberg
resigned as a director on May 3, 1999. Mr. Leontiev's term expired on July 26,
1999 and was not reelected as a Director.

(2) All Directors receive $150 per board meeting or committee meeting attended

Director in connection with his duties as a Director are also reimbursed by SI
Diamond. This amount is not reflected in the above table.

(3) All of SI Diamond's outside Directors participate in the Amended and
Restated 1992 Outside Directors Stock Option Plan, under which the SI Diamond
may grant stock options to any Director who is not a full time salaried employee
of the Company. On January 26, 1999, each Director at that time was granted
20,000 options under this plan at a price of $2.27 per share. These option
grants became exercisable in full on that date. The Board of Directors also
established the 1998 Directors and Officers Stock Option Plan in 1998. Each

           All of Directors have retained the right to pursue additional
business activities that are not competitive with the business of SI Diamond,
and do not adversely affect their performance as Directors. If, as and when
conflicts of interest arise, the nature of the conflict must be fully disclosed
to the Board of Directors, and the person who is subject to the conflict must
abstain from participating in any decision that may impact on his conflict of
interest. Except for this disclosure and abstention policy, the Directors will
not be in breach of any fiduciary duties owed to SI Diamond or the shareholders
by virtue of their participation in such additional business activities.

                              EMPLOYMENT AGREEMENTS

         SI Diamond has an employment agreement with Dr. Zvi Yaniv, its
President and Chief Operating Officer, which was entered into on June 1, 1996.
Under the terms of this agreement Dr. Yaniv was to be paid a base salary of
$125,000 per year. The contract was amended to adjust Dr. Yaniv's salary to
$175,000 per year effective January 1, 1999. All contingent compensation related
to bonuses or performance goals were eliminated.

         SI Diamond also provides Dr. Yaniv with the use of an automobile. The
employment agreement may be terminated by either party, with or without cause,
by giving 30 days notice of termination to the other party.

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         As of December 31, 1998, SI Diamond had notes payable to its chief
executive officer. These notes resulted from the CEO's personal guarantee of a
loan made by an investor. The loan was made to the CEO, who in turn loaned the
money to SI Diamond under the same terms. In April 1999, these notes payable
were assigned by the CEO to the holder of the underlying note payable. The
holder of the underlying note payable converted this loan into shares of the
Company's common stock.

     In October 1998, Electronic Billboard Technology, Inc., a subsidiary of SI
Diamond entered into a Patent Assignment and Royalty Agreement with Advanced
Technology Incubator, Inc., ("ATI") a corporation based in Austin, Texas and
owned by Dr. Zvi Yaniv, SI Diamond's President and Chief Operating Officer.
Under the terms of the agreement, ATI agreed to assign U.S. Patent No. 5,469,187
related to certain LCD technology to EBT in exchange for an initial payment of
$200,000. In addition, ATI is entitled to receive a royalty of 5% of gross
revenue related to products using this patent. EBT intends to use this
technology in the development of its next generation electronic billboard
product. EBT may terminate this assignment at any time upon 30 days written
notice to ATI. The assignment may be terminated by ATI if, within two years of
the first sale or lease of a billboard using this technology, cumulative royalty
payments under the agreement have not totaled $500,000, or if payments do not
equal $500,000 in any one year period following this initial two year period. If
the assignment is terminated by ATI, EBT will be granted a non-exclusive
worldwide license to use the technology under terms similar to those contained
in this agreement.

     ATI had the right to terminate this agreement if the initial payment was
not received by February 15, 1999. This date was extended until April 15, 1999.
In April 1999, the agreement was amended to allow additional extensions, in
three month increments, for a period of up to one year from April 15, 1999. In
exchange for each three month extension, EBT was obligated to pay ATI $12,500.
The $200,000 initial payment required for the actual assignment of the Patent
under the agreement will be reduced for any amounts paid for the extension
periods. EBT elected to exercise each of its extension options and paid ATI a
total of $50,000 through January 2000. In April 2000, unless the contract is
renegotiated, EBT must pay $150,000 to complete the assignment of the patent, or
allow its option to acquire the patent to lapse.
