                   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 ("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 our CFE technology. It is our intention to license our HyFED
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 PRODUCING REVENUE

         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 one time, up front, payment of approximately $5.6 million. We have no
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 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 NET LOSSES

         We have a history of net 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 net income and losses as shown below:

                           1994                       $ (7,255,420)

                           1996                       $(13,709,006)
                           1997                       $ (6,320,901)
                           1998                       $ (3,557,548)
                           1999                       $  1,118,134
                           2000                       $ (7,671,014)
</TABLE>

         Although we expect to be profitable in the future, we may not be. Our
profitability in 2001 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. McGladrey &
Pullen, LLP, independent auditors of the Company, have expressed uncertainty as
to our ability to continue as a going concern based, in part, on our accumulated
losses from operations in prior years. See "Independent Auditor's Report." We
have funded our operations to date primarily through the proceeds from the sale
of our equity securities and debt offerings. In the past, we were primarily a
contract research and development organization, but are in the process of
transitioning to an organization that is primarily dependent on products sales
and other business operations. 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 and introduction
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. This lawsuit was
settled in January 2000 for a total payment of $1,450,000 of which $1,000,000
was funded by a bonding company that had provided a bond on the original
contract and $450,000 was funded by us. We were also named as a third party
defendant in another suit by other guarantors under the bond. This related
lawsuit was settled in January 2001 for a total payment of $800,000 to the
bonding Company. The majority of that settlement was paid by other defendants in
the case. We agreed to pay $150,000 of this settlement. We have no further
liability in either of these matters, beyond the $200,000 of notes payable
recorded on the balance sheet.


                                    Page iii
<PAGE>   5

         We have other lawsuits that arise in the normal course of business,
including lawsuits by various trade creditors related to payment of amounts due.
We expect all lawsuits 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 iv
<PAGE>   6

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, product introduction, product manufacturing at SBOA, product marketing,
and administrative overhead. The majority of R&D expenditures are for the
development of our CFE technology and our electronic display products. Our
business model is based on our installing electronic display products at
customer sites at our cost and then deriving advertising revenues from the
signs, or from the outright sale of these products. Installation of our products
at customer sites will require a significant capital investment on our part. Our
outdoor electronic billboard product is available now and we have installed
three units at test sites, although only minor revenues have been generated. We
also have a variety of smaller electronic display products available that are
intended primarily for indoor use. 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 our current cash
levels are not sufficient to fund operations until we reach that point. We have
the existing resources to continue operations for approximately four to six
weeks. 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 CHANGES 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 v
<PAGE>   7

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.

         We have also licensed certain patents related to carbon nanotube
technology from Till Keesman. We are obligated to pay 50% of any royalties that
we receive related to these patents to Mr. Keesman. If minimum royalties of
$500,000 have not been paid by the end of May, 2002, the license will terminate
at that time. If minimum royalties of $500,000 have been paid by the end of May
2002, but minimum royalties of $1,000,000 have not been paid by May, 2004, the
license will terminate at that time.

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. 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 vi
<PAGE>   8

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:

         We currently have one commitment for future government funding of
approximately $580,000. We do not intend to seek any government funding unless
it directly relates to achievement of our strategic objectives. A significant
portion of the cost associated with the revenue recognized in 2000 were costs
paid to a subcontractor on the project.

         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 and
other industries. Our research is at FEPET is focused on identifying key
applications of this technology. In addition to the electronics industry, we are
also working on applications of our technology in the medical, x-ray, and
wireless communication industries. Based on our research, we are currently
engaged in the development of uses for our Carbon Field Emission ("CFE")
technology. We are also developing 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. We believe that our greatest growth opportunity lies in CFE products
and the development of our electronic display products for indoor and outdoor
point of purchase advertising.

         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 technology. 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 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 technology, electronic billboards, and related indoor and outdoor
electronic display products.

         We conduct our operations through our subsidiaries. EBT is engaged in
the development and introduction of electronic display products, such as
billboards, outdoor display devices for use in the fast food or other
industries, and indoor point of sale products. EBT installed three outdoor
electronic billboards at test sites in 2000. SBOA manufactures and sells all
types of signage. FEPET is conducting research on and developing uses for 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.

         We incurred research and development expense of $2,620,623 in 2000 and
$1,475,655 in 1999. 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 SEGMENTS

         FIELD EMISSION PICTURE ELEMENT TECHNOLOGY, INC. FEPET was incorporated
in January 1997 and 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 our research has indicated that
carbon is actually a better emitter. Accordingly, our research is now focused in
the broader area of CFE technology and its application to the electronics,
medical, x-ray, and wireless communication industries.

          We are developing a new display technology, the HyFED, which combines
what we believe to be the best properties of cathode ray tubes ("CRTs") and our
CFE technology. We are also extending our research to apply our technology in
other non-display related fields. Our plans for this technology are discussed in
greater detail in the section entitled "Business Development Strategies" later
in this report. We successfully completed phase I of our HyFED development by
demonstrating a 4" monochrome proof of concept. We have now started phase II to
develop a 4" full color proof of concept as a precursor to development of a 60"
display.

 Another 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, could be a natural step in the improvement of the Company's
electronic billboard and other electronic products.

         ELECTRONIC BILLBOARD TECHNOLOGY, INC. EBT was incorporated in January
1997 to focus on developing sun-readable display products for outdoor use. Its
initial primary product focus was an electronic billboard which would enable the
outdoor advertising industry to exploit the Internet and information revolution
by placing ads at different locations at different times. We installed three
outdoor billboards at test locations in 2000. Two of the billboards were
installed under a pilot program with Eckerd Corporation, a subsidiary of
JCPenney. We also installed one outdoor billboard at a Cinemark location, which
is currently not in use. We have also developed displays for indoor use that
could be used as part of an overall point of purchase advertising program. 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 assists in the
installation of the electronic billboard product. SBOA has two significant
customers (see Note 16 to the consolidated financial statements). SBOA has no
significant raw material suppliers.

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 display products. We currently have a
manufacturing facility that we acquired through our acquisition of SBOA to
assemble 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>   12

FEPET

         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 over the next few years 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 TECHNOLOGY. The major short run focus of FEPET is the continued
development and commercialization of its CFE technology. Our current research
and development efforts are focused on developing our technology for use in the
display, medical, x-ray, and wireless communication industries. We have two main
potential product for the display industry, the HyFED and the PET.

          HYFED - We have developed a new display technology, the HyFED. HyFED
combines what we believe to be the best properties of CRTs and our CFE
technology using our proprietary diamond/carbon thin films. We expect the HyFED
to compete with Plasma Displays in both cost and quality. 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 was 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 has been
expanded and 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 within
the next eighteen months.

         PET - The PET is a basic display device which could be used in many
display applications, including electronic billboards. 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 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 within the next year 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 are currently working with a large Japanese
display manufacture to complete development of the PET and have received
$600,000 from this company to continue our development of the PET.

         OTHER CFE PRODUCTS - We are also concentrating on developing uses for
our technology in industries other than the display industry. We have developed
a carbon cold cathode electron source, which can be utilized for many
non-display related applications such as x-ray tubes, medical devices,
microelectronics, nanotechnologies, low-power thrusters, CRT electron guns,
wireless communications, and polluted air scrubbing. We have signed a license
agreement with Oxford Instruments to provide cathodes for use in their products
in the field of X-ray technology. We have also received a grant of approximately
$582,000 from NASA to develop low power thrusters using our technology. This
grant was received as a follow up to an initial feasibility study funded by NASA
in the amount of approximately $67,000. We are also researching the use of our
technology in other industries and are encouraged by the preliminary results
that we have achieved to date.

EBT

         ELECTRONIC DISPLAY PRODUCTS. EBT has developed and markets several
electronic display products, including the E-Window, the E-Banner, the Digital
Poster, and an electronic billboard. We are focusing our current marketing
efforts on our indoor electronic display products. We are targeting major
national retailers for the use of these displays in conjunction with existing
on-site signage. We intend to lease or operate our display products through
joint venture arrangements with these retailers. To facilitate our entry into
this market, we have signed marketing agreements 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. We have also signed a marketing agreement
with Kaleidoscope Communications, a global advertising and marketing agency. As
a result of the Vision Mark agreement, we signed an agreement with Eckerd
Corporation, a subsidiary of JCPenney to install two electronic billboards on a
test basis in 2000. We installed these billboards at stores in Clearwater,
Florida and Austin, Texas in 2000. As a result of the successful tests of the
outdoor signs at these two sites, we signed an additional agreement with Eckerd
Corporation in February 2001 to install indoor point of sale displays at ten
Eckerd locations in four states. We expect these indoor displays to be installed
by mid April 2001.

         As a result of our agreement with Kaleidoscope, we signed an agreement
with a national quick service restaurant chain to install our E-Window and
E-Banner products at several locations for a test that will run through June
2001. It is expected that these tests will result in an increase in the average
check size and an increase in the unit sales of the items featured on the
displays. We also intend to use Kaleidoscope to sell the advertising on displays
that we own that are installed at customer locations, such as with the Eckerd
agreement described above. Kaleidoscope, which is affiliated with DDB worldwide,
one of the largest advertising agencies in the world, will bring us needed
expertise in the sale of advertising.

         We are also targeting other national retail chains, banks, restaurants,
and others for our display products. We previously signed an agreement with
Cinemark, a national theatre chain, for installation of a billboard at a test
site. Because of the difficult financial conditions currently being experienced
by the theatre industry and because of the limitations on advertising at these
locations, we are evaluating this agreement. We have the ability to terminate
this contract with 30 days notice and will do so if we determine that our
resources can be better deployed elsewhere.

         Our outdoor 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 also developing an outdoor electronic billboard
using Liquid Crystal Display ("LCD") technology. This LCD billboard, when fully
developed using our patented technology, is expected to provide similar quality
at approximately one third the cost of existing outdoor electronic billboards.
We have developed a demonstration model of our LCD billboard that was completed
in January 2001. The model is modular in design and consists of four one foot by
one foot modules. The Company expects to eventually install outdoor electronic
billboards using this technology.

         As discussed above, we completed installation of our first electronic
billboard at a customer site in 2000 and allowed the customer an extended test
period. Our benchmark for success was to develop an operational outdoor
billboard and we were successful. Since this is a new concept and we have no
historical results available to us, we are unable to predict future revenues
with sufficient certainty and accordingly, pursuant to the provisions of
Financial Accounting Standards Board Pronouncement No. 121 ("FAS 121") we
reduced the carrying value of these display units to the lower end of the range
of estimated liquidation values. Notwithstanding the provisions of FAS 121, we
expect our strategy (see MD&A) to be successful.


                                     Page 4
<PAGE>   14

         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 believe that TDS continued to use our patented
technology after the termination of the agreement and as described in greater
detail in Item 3, the matter is currently under litigation. We are seeking back
royalties for all products shipped by TDS which involve our technology and for
payment of future royalties related to all products sold which involve our
technology.

SBOA

         CUSTOM SIGN MANUFACTURING. SBOA is continuing to target customers in
its home geographical area of Central Texas and selected national accounts using
its own internal sales force.

COMPETITION

EBT

         ELECTRONIC BILLBOARDS. We believe that the proprietary version of the
VFD and LCD technologies 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

         We are unaware of any other organizations developing an electronic
billboard using technologies similar to ours. However, these are existing
technologies 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.

         OTHER ELECTRONIC DISPLAY PRODUCTS. Our other electronic display
products face competition from a variety of similar products and a variety of
sources. Our E-window product is a unique product with a patent pending, which
gives us an advantage in this area. Our success in this area is dependent on our
ability to market our products. We believe our marketing efforts are enhanced by
our ability to provide a complete product line, including the sun-readable
outdoor displays, and the E-window product.

FEPET

         CFE TECHNOLOGY. 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. Other competition for the CFE technology comes from the
existing technologies used in the industries for which the Company is developing
the technology. These technologies vary from industry to industry.

SBOA

         CUSTOM SIGNS. SBOA faces competition from a variety of national,
regional and local custom sign manufacturers. The custom sign business is an
extremely competitive business.

TECHNOLOGY AGREEMENTS

         MCC. We acquired 62 patents and patent applications related to the CFE
technology from MCC in 1998. We are obligated to pay MCC a royalty of 2% of
future commercial revenues related to these 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.

         TILL KEESMAN. We licensed 6 patents from Till Keesman in exchange for a
payment of $250,000 payable in shares of our common stock. Under the terms of
the agreement, we are obligated to pay license fees equal to 50% of any
royalties received by the Company related to these patents. We are allowed to
offset certain expenses, up to a maximum of $50,000 per year, against payments
due under this agreement. The agreement also contains provisions related to
minimum license fee payments. If we do not pay minimum additional license fees
of $500,000 by May 2002, the license will terminate at that point. If we do not
pay additional cumulative license fees of $1,000,000 (including any fees applied
toward the previously described minimum due in May 2002) by May 2004, the
license will terminate at that point. We are not obligated to make any
additional payments, but the license may terminate if these payments are not
made.

INTELLECTUAL PROPERTY 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.

         We own 57 issued patents, two allowed patents, and have 56 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. The cost of compliance with
these regulations has not been significant in the past and is not expected to be
material in the future.

         In the past, a portion of our revenues have consisted of reimbursement
of expenditures under U.S. government contracts, although we recognized no such
revenue in 1999 and only $352,341 in 2000. These reimbursements represent a
portion of the costs associated with such contracts. As of December 31, 2000, we
have only one grant, however we received three additional small grants
subsequent to that date. 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.

EMPLOYEES

         As of March 14, 2001, we had 42 full-time employees, including three
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.

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. SBOA also
leases a 10,000 square foot facility in Austin that it uses for its
manufacturing operations under a lease expiring in August 2001. 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 named Plasmatron, SI Diamond, and Westchester Fire
Insurance Company as defendants. Semi-Alloys claimed a breach of contract
related to $1 million of coating equipment that Plasmatron delivered in 1993,
prior to our ownership of Plasmatron. Semi-Alloys claimed the equipment did not
perform as required under the contract. Semi-Alloys sought to recover
compensatory, consequential and incidental damages. The plaintiff sought damages
of approximately $8.0 million. 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. The plaintiff
agreed to accept a total payment of $1,450,000 in exchange for a release of all
claims. We agreed to pay a total of $450,000 of this settlement. A total of
$225,000 was due at signing and 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 first two notes were paid in 2000. The remaining note of
$100,000 is due in July 2001.

         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 seeking to recover the $1,000,000 paid as a
result of the Semi-Alloys settlement, plus legal costs. 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. This case was
settled in January 2001. As part of the settlement, SI Diamond Technology, Inc.
agreed to contribute $150,000 as part of an overall settlement package to which
all defendants contributed a total of $800,000. The terms of the settlement call
for us to pay $50,000 no later than June 1, 2001. The balance of $100,000 is in
the form of a note due in July 2003.

     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 Plasmatron. We were served with notice of this suit on August 5,
1998. The plaintiff seeks damages of approximately $25,000. All amounts claimed
as owing by TFI are recorded as liabilities in the consolidated financial
statements. We believe that the ultimate resolution of this matter will not have
a material impact on our consolidated financial statements.

         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 settled this
suit in 2000 for a total payment of $28,000, which represented less than two
months rent during the vacancy period.

         On November 16, 2000, Lance Adams, the former owner of Sign Builders of
America, Inc. filed suit against SI Diamond Technology, Inc and Sign Builders of
America, Inc. in the 20th Judicial District Court in Travis County, Austin Texas
for alleged breech of the purchase agreement in which the Company purchased
SBOA. Of the initial purchase price of $1,800,000, a total of $1,350,000 was
paid in cash and stock in September 1999. The remainder of $450,000 was due in
the form of a note due in two installments in March and September 2000. The
agreement contained provisions that allowed for a downward adjustment of the
sales price if certain sales levels were not achieved and allowed offsets for
other claims against the note. In February 2000, an initial purchase price
adjustment reduced the note to $250,000 and a payment $125,000 plus interest was
made in March 2000. In September 2000, the Company notified Mr. Adams of
additional purchase price adjustments and other offsets which eliminated the
remaining balance due on the note. Mr. Adams disagreed with these offsets and
filed suit for breech of the agreement, alleging damages of not less than
$175,000. The Company has filed a counterclaim against Mr. Adams for amounts due
back to the Company as a result of these offsets. The Company expects the
ultimate resolution of this suit to have no material impact on the consolidated
financial statements.


                                    Page 10
<PAGE>   20

         The Company previously had a royalty agreement with Texas Digital
Systems, Inc. (TDS) which was terminated by TDS pursuant to the terms of the
agreement as of December 31, 1999. Under the terms of the agreement, TDS was
prohibited from using the Company's technology after the termination of the
agreement. The Company believed that TDS was continuing to ship products using
our technology and contacted TDS. TDS responded, in part, by filing suit against
the Company and its subsidiary, Electronic Billboard Technology, Inc. for breach
of contract in the 272nd Judicial District Court in Brazos County Texas on July
26 , 2000. The Company was not served with notice of this suit until December 5,
2000. It is the Company's view that the TDS claim against the Company has little
merit and that a significant reason that TDS filed suit was to obtain venue in
its home venue of Brazos County rather than in the Company's home county of
Travis County. TDS has alleged unspecified damages in excess of $500,000. The
Company intends to vigorously pursue its claim against TDS and seek damages and
an injunction against TDS for continuing to use the Company's technology in TDS
products after the termination of the agreement.

         The Company and its subsidiaries are also defendants in various other
lawsuits related to the non-payment of invoices when due, or minor employment
matters. 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. If resolution of any of these suits results in a liability greater than
that recorded, it could 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 2000.

         On March 14, 2001, the closing sale price for our common stock as
reported on the OTC Bulletin Board system was $0.64. As of March 14, 2001, there
were approximately 325 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. Our convertible preferred stock has a liquidation
preference of $1,145,123 as of December 31, 2000.

          Information required in this Item 5 of our Annual Report on Form
10-KSB/A concerning information as to all equity securities issued by us during
the last three fiscal years that were not registered under the Securities Act of
1933 and that is not contained in "Item 6. Management's Discussion and Analysis
of Financial Condition and Results of Operations - Financial Condition," or in
Note 10 to the Notes to the Consolidated Financial Statements contained in this
Annual Report on Form 10-KSB/A is presented below:

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 14 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.

1998 Notes and Private Placements

         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.

Minority Interest in Subsidiary

         In February 2000, the Company issued 200,000 shares of its common stock
to Nomura Holding Company to acquire the shares of stock in the Company's FEPET
subsidiary held by Nomura Holding Company. These shares were included on a
registration statement filed in June 2000.

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

         The following discussion should assist in understanding our financial
condition and results of operations for the years ended December 31, 2000 and
1999 and our liquidity and capital resources for 2001. 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.

                                     OUTLOOK

         We expect our cash needs for 2001 to be approximately $3.5 million. We
intend to fund those needs through a combination of SBOA sales, reimbursements
for research, license agreements, and issuance of debt and equity securities.
Successful introduction of our electronic display products resulting in
significant customer orders would cause our cash needs to exceed that, however,
such customer orders would also result in increased availability of funding.

         We anticipate that losses will continue in 2001 as we continue to fund
the development of our CFE technology and continue installations of our
electronic display products. We expect to reach break-even on a monthly
operating basis by the end of 2001. 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 expect to continue our concentrated research and development of
FEPET's technology in 2001. EBT developed new electronic display products in
2000 intended primarily for indoor use as point of sale displays. In February
2001, we signed an agreement with a national quick service restaurant chain to
install our indoor electronic displays on a test basis. We also signed an
agreement with Eckerd Corporation, a subsidiary of JCPenney, to install indoor
point of sale electronic displays at 10 test locations beginning in March 2001.

         We developed a plan to allow ourselves to maintain operations until we
are able to sustain ourselves on our own revenue. 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 display products. 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 of our 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.

                              RESULTS OF OPERATIONS

         2000 Compared to 1999. The Company had $2,724,830 in revenues during
2000, as compared with $6,752,104 during 1999. The main reason for the decrease
was that the 1999 revenues included $5,555,556 in license fee received from
Canon, Inc. Commercial (non-governmental) sales accounted for $2,372,489 of the
2000 revenue and all revenues in 1999. Our 2000 commercial revenue included
$2,257,013 from SBOA, $2,632 from FEPET, and $112,844 from EBT. The 1999
commercial revenue came from FEPET, EBT, and SBOA in the amounts of $5,794,269,
$300,282, and $657,553, respectively. The 1999 FEPET revenues were composed of
license fees of $5,555,556 and $238,713 of research revenues. The 2000 revenues
were primarily the result of the sale of research services. The EBT revenue in
1999 was primarily the result of royalty payments from TDS. The 2000 EBT revenue
included $25,500 of royalty payments from TDS and the remainder was from the
sale of advertising and miscellaneous display products. We recognized no revenue
from government funded projects in 1999 and $352,341of revenue from government
grants in 2000. We received approval for an additional grant near the end of
2000, that will result in approximately $580,000 of revenue in 2001. 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 our strategic
objectives.

         We are unable to predict our 2001 revenues by segment with any degree
of accuracy at the present time, however we had a revenue backlog of $1,186,858
at December 31, 2000. The 2000 backlog was composed of $604,525 from our SBOA
subsidiary and $582,333 from a NASA grant. This represents an increase over the
backlog at December 31, 1999 backlog, which was composed of approximately
$211,000 from SBOA and approximately $67,000 from a NASA grant.

          In 2000, our cost of sales were $1,949,042, or a margin of 28%. For
1999, our costs of sales were $674,380, resulting in a margin of 90%. The reason
for the large decrease in margin was the royalty payment received in 1999, which
had only negligible costs associated with it. We expect future margins to
improve from 2000 levels as we begin to receive increased advertising revenues
from the installation of our display products at customer locations. We expect
margins at SBOA, our main segment, to improve slightly from 2000 levels.

         Our selling, general and administrative expenses increased to
$3,881,141 in 2000 from $3,356,675 in 1999. This increase results from a
combination of factors including increased overhead associated with operating
our SBOA subsidiary for the entire year and a $675,000 marketing expense related
to the agreement signed with Eckerd Corporation. We expect selling, general and
administrative expense in 2001 to be similar to 2000.

         Company sponsored research and development expenses increased in 2000
to $2,620,623 from $1,475,655 in 1999. Development expense related to our
electronic billboard product is the primary reason for the increase. Research
and development expense at EBT increased from $817,436 in 1999 to $1,732,690 in
2000. All of EBT's research and development was focused on its indoor and
outdoor electronic display products. Research and Development expense at FEPET
increased from $658,219 in 1999 to $887,933 in 2000 due to a general higher
level of activity. 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, however we expect
research and development expenditures to be substantially reduced from 2000
levels for two reasons. First, FEPET has a much higher level of commitment for
external funding in 2001. In addition to the NASA grant in the amount of
approximately $582,000, which existed at December 31, 2000, FEPET has signed a
$600,000 contract with a large Japanese display manufacturer and three other
small research grants from the US Government. Second, EBT's display products are
market ready and will require much lower levels of ongoing research and
development expenditures. We may apply for other government grants, but only if
those grants are specifically related to activities we are already pursuing to
accomplish our own strategic objectives. We spent $2,620,623 on unreimbursed
research and development in 2000 and expect to spend at least $1,000,000 in
2001 on unreimbursed research and development.

Taxes in 1999 are foreign taxes related to the Canon license agreement. There
were no foreign taxes in 2000.


                                    Page 15
<PAGE>   25

         The largest single component of cost that we incur is payroll related
expense. In 2000, we incurred approximately $3.1 million of payroll related
expense, of which $0.6 million is included in costs of sales related to SBOA.
The remaining amount is included in selling, general and administrative expense,
and research and development. As a result of reductions that we have made, our
annualized current cost of payroll is approximately $2.6 million, with
approximately $0.6 million still related to SBOA cost of sales. We do not expect
our payroll levels to increase in 2001 until such time as additional employees
may be required because of increased revenues.

         As discussed in greater detail in Note 6 to the financial statements,
our operating results for 2000 include $1,838,261 in FAS 121 impairment charges.
We do not expect to have any impairment charges in the future. The entire gain
on disposal of assets of $375,000 in 2000 and $250,000 of the gain in 1999
resulted from the sale of our previous domain name, diamond.com. The balance of
the gain in 1999 resulted from minor equipment disposals. We incurred net
realized and unrealized losses on marketable securities in 2000 of $449,504 as
compared with net realized and unrealized gains on marketable securities in 1999
of $309,172. The marketable securities were invested primarily in NASDAQ stocks
and the overall results are similar to the overall performance of the NASDAQ
during those time periods. We have liquidated the majority of our marketable
securities portfolio and do not expect gains or losses in 2001 to be
significant.

                         LIQUIDITY AND CAPITAL RESOURCES

         Our cash position decreased from $348,832 at December 31, 1999 to
$8,818 at December 31, 2000. Net cash used in operating activities was
$5,205,723 in 2000, as opposed to cash provided by operating activities of
$868,226 in 1999. The cash used in operations was primarily the result of the
net loss incurred in 2000. Our operating results in 2000 included non cash
charges of $1,838,261 related to impairment charges, $679,646 related to
warrants and stock issued for services, and $544,794 related to depreciation.
The major reason that we were profitable in 1999 was the royalty revenue
received from Canon, Inc. in that year.

         Cash provided by investing activities was $233,192 in 2000 as compared
with cash used in investing activities of $1,736,134 in 1999. 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 2000 was the result of the sale of the majority of our
marketable securities portfolio and proceeds received from the sale of the
entity which had purchased our previous domain name. No material commitments
exist as of December 31, 2000 for future purchases of capital assets.

         In 2000, we had cash provided by financing activities of $4,632,517.
These funds were primarily the result of the sale of equity securities and were
primarily used to fund our operating losses. This was a substantial increase
over the cash provided by financing activities of $1,214,104 in 1999, when we
had a much smaller need for operating capital as a result of the license
agreement signed with Canon, Inc.

         As of December 31, 2000, our current liabilities exceeded our current
assets by $888,644, with a current ratio of .4 to 1, compared to a working
capital deficit of $356,106 and a current ratio of .8 to 1 as of December 31,
1999. This decrease is primarily the result of the reduction in our cash and
marketable securities positions. Current liabilities decreased by $443,129 from
1999 to 2000. The primary reason for this decrease is the total payments of
$350,000 made related to a lawsuit settlement that was included in accrued
liabilities at December 31, 1999. We do not expect the aggregate payments
related to lawsuits to exceed the liabilities recorded in the financial
statements and we do not expect aggregate payments related to lawsuits to affect
our liquidity beyond using resources that we have set aside to make payments at
the appropriate times. If resolution of any of these suits results in a
liability greater than that recorded, it could have a material financial impact
on us.

         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, 2000 were exercised, we would collect proceeds of
approximately $466,000. (See Note 12 to the Consolidated Financial Statements.)
Proceeds from the exercise of warrants totaled approximately $375,000 in 2000
and $650,000 in 1999. Given that the current price of our common stock is below
the exercise price of our outstanding warrants, it is unlikely 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. At the
present time, it is also unlikely that significant amounts of options will be
exercised, since for current in-the-money options, the current market price of
our common stock does not exceed the exercise price of those options by a
significant amount.


                                    Page 16
<PAGE>   26

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
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, McGladrey & Pullen, LLC, expressed uncertainty as to the
ability of the Company to continue as a going concern based on accumulated past
losses from operations. See "Independent Auditor's Report."

         Following is a summary of debt and equity proceeds that the Company has
received from January 1, 2000 through the date of this filing:

2000 Private Placements

         During 2000, in a series of private placements under Regulation D of
the Securities Act of 1933, we issued a total of 3,992,242 shares of our common
stock in exchange for $3,455,000. The shares were issued at a slight discount to
the market price of our common stock at the time of issuance. The Company filed
registration statements in June and November 2000 to register these shares and
to update the registration of other previously registered shares.

2000 Notes

         In June 2000, we borrowed a total of $375,000 from two separate
entities. We repaid $125,000 in January 2001. The remaining $250,000 is due in
June 2001 and is convertible into our common stock at the option of the lender
at a rate of $0.675 per share. The shares into which this note are convertible
were registered on a registration statement declared effective July 17, 2000.

2001 Private Placements and Notes

         Through March 12, 2001 in a series of private placements under
Regulation D of the Securities Act of 1933, we issued a total of 1,178,284 and
received total proceeds of $522,047. These shares have not yet been registered.
It is likely that we will continue to fund our operations through the use of
private placements and Notes until such time as we are able to sustain ourselves
on our own revenue.

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.

Common Stock for Services

         As a result of a marketing agreement and related consulting and
advisory agreement with Vision Mark, LLC and C&A Consulting Services, LLC., the
Company issued 300,000 shares of its common stock in January 2000 to C&A in
connection with an agreement to provide an electronic billboard to Eckerd
Corporation, a subsidiary of JCPenney , Inc. The shares were valued at $675,000
based upon the market price of the common stock at the time of issuance. A
registration statement covering these shares was declared effective June 23,
1999 and amended on several occasions since that date.

<PAGE>   27

Patent Acquisition

         In June 2000, the Company acquired a patent valued at $250,000. In
exchange for this patent, the Company issued 240,164 shares of its common stock.
A registration statement covering these shares was declared effective July 17,
2000. We may acquire additional patents in the future, but at the present time
we have no plans to do so.

                            SEASONALITY AND INFLATION

         SI Diamond's business is not seasonal in nature. Management believes
that SI Diamond's operations have not been affected by inflation.

                          INDEPENDENT AUDITOR'S REPORT


To the Board of Directors and Shareholders
SI Diamond Technology, Inc.
Austin, Texas

We have audited the accompanying consolidated balance sheet of SI Diamond
Technology, Inc. and Subsidiaries (collectively, the "Company") as of December
31, 2000 and the related consolidated statements of operations, stockholders'
equity and cash flows for the year then ended. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of SI Diamond
Technology, Inc. and Subsidiaries as of December 31, 2000, and the results of
its operations and its cash flows for the year then ended in conformity with
generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in Note 1 to the
consolidated financial statements, the Company has suffered recurring losses
from operations and the Company has relied primarily on capital raised through
offerings of common stock, preferred stock, and convertible debt securities to
fund its operations. It is uncertain whether the Company will be able to secure
additional capital to fund its operations and this raises substantial doubt
about the Company's ability to continue as a going concern. The consolidated
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                          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, OPERATIONS, AND LIQUIDITY:

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

         The Company launched its electronic billboard product in 2000,
installed test units at three locations, and began receiving nominal amounts of
revenue related to these signs. The Company is continuing to focus on rolling
out its full line of display products. The Company is also continuing to pursue
license agreements for its technology. Until the Company is able to operate
profitably as a result of either revenues from its display products or revenue
from license agreements, it will continue to seek additional funds through the
equity markets, or raise funds through debt instruments to allow it to maintain
operations. There is no assurance that license agreements will be signed, that
commercialization of the Company's technology and products will result in income
from operations, or that funds will be available in the equity or debt markets.
Management believes it will continue to be able to secure additional short term
funding, to allow the Company to continue operations until it achieves
profitability. 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 since the time of its
initial public offering in 1993 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 by
others. To the extent that other funding is not available, the research and
development performed is being internally funded by the Company.

         The accompanying financial statements have been prepared in conformity
with generally accepted accounting principles, which contemplates continuation
of the Company as a going concern. However the Company has sustained substantial
operating losses since inception and continues to sustain losses. In view of
this, realization of a portion of the assets in the accompanying balance sheet
is dependent upon continued operations of the Company. Management believes that
actions currently being taken will allow it to achieve profitability and allow
the Company to continue as a going concern.

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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

Revenue recognition

         In 1999, the staff of the Securities and Exchange Commission issued
Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements,
("SAB 101"). SAB 101 summarizes some of the staff's interpretations of the
application of the generally accepted accounting principals to revenue
recognition. The Company adopted SAB No. 101 in the fourth quarter of 2000. The
accompanying financial statements comply with the provisions of SAB 101.

         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 earned under
the terms of the agreement. Advertising revenues are recognized as revenue in
the period in which the advertising runs.

         The Company's revenues include reimbursements under agreements to
perform research and development for others. 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 and recognizes
revenue when it is billed pursuant to the terms of the contract. Agreements with
other entities generally allow the other entity to license the Company's
technology upon completion of the project. Revenue under these contracts is
recognized when it is earned pursuant to the terms of the contract.

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 equity securities

         The Company's securities investments that are bought and held
principally for the purpose of selling them in the near term are classified as
trading securities. Trading securities are recorded at fair value on the balance
sheet in current assets, with the change in fair value during the period
included in earnings.

Accounts receivable

         The Company's SBOA subsidiary frequently sells products to smaller
companies on credit, but requires deposits and prepayments where appropriate. It
is the Company's policy to record reserves for potential credit losses. Since
inception, the Company has experienced minimal losses.

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, 2000 and 1999.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

Property and equipment

         Property 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. The majority of patent costs, which consist primarily of
legal fees, are expensed as incurred. The Company has capitalized the
acquisition cost of patents acquired in 2000 and is amortizing the cost of those
patents over a period of 25 months.

         Goodwill represents the excess of the cost of the SBOA acquisition over
the fair value of the net assets at the date of acquisition and is being
amortized over a period of 15 years. Amortization expense charged to operations
was $26,574 in 2000 and $8,858 in 1999. In connection with this acquisition, the
Company also signed a covenant not to compete. The covenant not to compete is
being amortized over a three year period. Amortization expense charged to
operations was $166,667 in 2000 and $55,556 in 1999.

Impairment

         At each balance sheet date, the Company evaluates the carrying amount
and the amortization period for its intangible assets and for its long-lived
assets. If an indicator of impairment exists, it is recorded at that time.
During the current year, property and equipment, as well as goodwill and
covenant not to compete were considered impaired. See Note 6 for details related
to the impairment write down.

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.

Minority Interest in Subsidiary

         At December 31, 1999, the minority interest in subsidiary represented
the 5% of FEPET owned by Diamond Pro-Shop Nomura, Company, Ltd. and was equal to
5% of the book value of FEPET. In February 2000, the Company acquired the
remaining 5% of FEPET. At December 31, 2000, no minority interest in any
subsidiaries exists. See Note 6 for more information on the acquisition of the
minority interest.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

Accretion on convertible preferred stock

         The Company's Series G Convertible 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, 2000 and 1999, respectively, have been treated as preferred
dividends. The entire amount reflected as accretion on convertible preferred
stock on the income statement relates to the Series G Preferred stock accretion

Income (loss) per common share

Basic per share amounts are computed, generally, by dividing net income or loss
by the weighted average number of common shares outstanding. Diluted per-share
amounts assume the conversion, exercise, or issuance of all potential common
stock instruments unless the effect is anti-dilutive, thereby reducing the loss
or increasing the income per common share. As described in Notes 10, 11 and 12,
at December 31, 2000, the Company had convertible preferred shares, options and
warrants outstanding to purchase a total of 1,145,123; 5,143,826; and 390,000
shares of common stock, respectively, at a weighted average exercise price of
approximately $0.85. However, because the Company incurred a loss in 2000, the
inclusion of those potential common shares in the calculation of diluted loss
per-share would have an anti-dilutive effect. Therefore, basic and diluted
per-share amounts are the same in 2000.

In calculating the basic (income) loss per common share, the premium earned by
the preferred shareholders, ($90,328 in 2000 and $140,163 in 1999) reduced the
net income in 1999 and increased the net loss in 2000.

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. Significant estimates include
the NOL reserve, warranty reserve, bad debt reserve, litigation reserves, and
the remaining value of impaired assets.

Disclosures about fair value of financial instruments

         The following methods and assumptions were used to estimate the fair
value of each class of certain financial instruments for which it is practicable
to estimate that fair value. For cash equivalents, the carrying amount
approximates fair value because of the short term nature of these instruments.
The fair value of the Company's notes payable and capital lease obligations is
estimated based on the quoted market prices for the same, or similar, issues, or
on the current rates offered to the Company for debt of the same remaining
maturities with similar collateral requirements. At December 31, 2000 and 1999,
the fair value of the Company's notes payable and capital lease obligations
approximates their carrying values. See Note 4 for information on the fair value
of marketable securities.

3.       OTHER INCOME

         The gain on disposal of assets included in other income (expense) was
primarily the result of the sale of the Company's previous domain name,
diamond.com. The entire gain of $375,000 in 2000 and $250,000 of the total gain
of $265,688 in 1999 related to the sale. The remainder of the gain in 1999 was
related to miscellaneous equipment sales. In 1999, the Company sold its domain
name, diamond.com for $250,000 in cash and notes receivable and an ownership
position in the entity that purchased it. In 2000, that entity was sold. As a
result of that sale, the Company received an additional $375,000 in cash and an
ownership position in the privately held company that purchased it. Because
there is no readily available market for the common stock received by the
Company, no value has been assigned to it at this time.

Other income (expense) is composed of the following:

PROPERTY AND EQUIPMENT:

         The electronic display units installed by the Company use technology
developed by the Company and are currently installed under test agreements with
customers. As a result, the Company is not able to predict future cash flows
with sufficient certainty and accordingly, pursuant to the provisions of
Financial Accounting Standards Board Pronouncement No.121, ("FAS 121"), has
reduced the carrying value of these display units to the lower end of the range
of estimated liquidation values of the display units, in the event that ultimate
implementation of the Company's strategy related to these boards is
unsuccessful. We had expected to implement our advertising strategy in the 4th
quarter, but because of delays in moving to the next stage with our customers,
our estimates were not met. Accordingly, the impairment adjustment was recorded
as of December 31, 2000.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

6.       IMPAIRMENT OF ASSETS (CONTINUED) :

SBOA GOODWILL AND COVENANT NOT TO COMPETE:

         In connection with the acquisition of 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 acquisition. This covenant not to compete
was being amortized over the three year period covered by the agreement. The
Company also recorded goodwill in connection with the SBOA transaction. This
goodwill was being amortized over a fifteen year period. As part of the
evaluation of intangible assets at December 31, 2000, the Company determined
that the goodwill and covenant not to compete were impaired as of that date. The
remaining net book value of these two intangible assets were written off and
charged to expense at that date. This determination was based on the failure of
SBOA to meet projected sales levels in the 4th quarter of 2000, which caused the
Company to reduce sales projections for future periods.

MINORITY INTEREST GOODWILL

         In February 2000, the Company had the opportunity to reacquire the
minority interest in its FEPET subsidiary and negotiated to do so by issuing
200,000 shares of the Company's common stock. The Company considered it to be a
good decision to reacquire the minority interest for this price, since we
considered this to be much less than the true value of the minority interest and
it enabled us to acquire total control of what we believe to be a very valuable
asset. The transaction was valued based on the market price of the common stock
issued. Since FEPET had a negligible book value, this resulted in $486,000 of
goodwill. However, since there was no future cash flow directly related to this
5% minority interest, FAS 121 required us to write the goodwill off as impaired
at the time that it was acquired. The transaction had no overall effect on
stockholders' equity since the value of the stock issued at the time
approximated the impairment write off.

7.       OPERATING LEASE OBLIGATIONS :

         The Company leases various facilities and equipment under operating
lease agreements having terms expiring at various dates through 2006. Rental
expense was $271,156 and $160,554 for the years ended December 31, 2000 and
1999, respectively.

         Future minimum lease payments under operating leases that have initial
or remaining noncancelable lease terms in excess of one year at December 31,
2000, were as follows:

</TABLE>

         As of December 31, 2000, the Company had net operating loss
carryforwards of approximately $60 million that expire from 2006 through 2018,
and are available to offset future taxable income. The majority of theses
carryforwards expire in 2010 and after. Additionally, the Company has tax credit
carryforwards related to research and development expenditures of approximately
$469,000 that expire through 2011 and foreign tax credits of approximately
$556,000 that expire in 2004.

         The Company's IPO, completed in 1993, and subsequent issuances of stock
have effected ownership changes under Internal Revenue Code Section 382. The
ownership changes resulting from these stock issuances may limit the Company's
ability to utilize any net operating loss carryforwards or credits generated
before the changes in ownership.

10.      CAPITAL STOCK:

Convertible Preferred Stock

         The Company has authorization for the issuance of 2,000,000 shares of
$1.00 par value preferred stock. As of December 31, 2000 and 1999, all preferred
shares outstanding were shares of the Company's Series G Preferred Stock. The
Series G Preferred Stock had a liquidation preference of $1,145,123 as of
December 31, 2000.

Series G

         From June 1997 through August 1997, through an exempt offering under
Regulation D of the Securities Act of 1933, the Company issued 1,700 shares of
its Series G preferred stock. The offering provided gross proceeds of $1,700,000
to the Company. 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. 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.

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. 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 at a price of $1.00 per share for a period of 5 years.

         During 2000, a total of 250 shares of Series G preferred stock were
converted into 317,397 shares of the Company's common stock and during 1999, a
total of 500 shares of Series G preferred stock were converted into 604,383
shares of the Company's 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 were convertible into 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. These shares were valued at $500,000 based on the market
price of the shares at the time of the transaction. This amount was considered
goodwill and written off as of the acquisition date. See note 6 for additional
information on the impairment write-off.

Company issued 3,992,242 shares of its common stock and received proceeds of
$3,455,000. These shares were issued at prices which represented a slight
discount to the market price of the stock at the time of the offerings. A
registration statement covering these shares was declared effective November 17,
2000.

         During 2000, the Company acquired a patent valued at $250,000. In

         As described in greater detail in Note 14, the Company has a marketing
agreement and related consulting and advisory agreement with Vision Mark, LLC
and C&A Consulting Services, LLC. As a result of these agreements, the Company
issued 300,000 shares of its common stock in January 2000 to C&A in connection
with an agreement signed with Eckerd Corporation, a subsidiary of JCPenney, Inc.
The shares were valued at $675,000 based upon the market price of the common
stock at the time of issuance. These shares were registered in June 1999.

         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. 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. A registration statement covering these
shares was declared effective June 23, 1999.

         As described in greater detail in Note 19, the Company issued a total
of 423,132 shares of common stock in connection with its acquisition of the
assets of SBOA. A registration statement covering theses shares was filed and
declared effective by post-effective amendment on November 29, 1999. In 2000,
the Company issued an additional 62,284 shares of its common stock in payment of
a note payable and related accrued interest arising in connection with the SBOA
acquisition. The amount of the note payable and accrued interest was $132,480.

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.

         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, 2000, a total of 1,713,236 shares remained
available for grant under the 1992 Employees Plan.

The following is a summary of stock option activity under the 1992 Employees
Plan:

11.      STOCK OPTIONS (CONTINUED) :

         In March 1992, the Board of Directors adopted the 1992 Outside
Directors' Stock Option Plan (the "1992 Directors Plan"), for purposes of
granting non-qualified options to non-employee directors of the Company. The
1992 Directors Plan was amended in 1994, 1996, 1997 and 1999. A total of
1,000,000 shares are reserved for issuance under the plan and are issued each

11.      STOCK OPTIONS (CONTINUED) :

         The fair value of each stock option granted in 2000 and 1999 is
estimated on the date of grant using the Black-Scholes option pricing-model with
the following weighted-average assumptions: no dividend yield for 2000 and 1999;
risk-free interest rate of 6.00% and 5.50% for 2000 and 1999, respectively; the
expected lives of the options are five years for 2000 and 1999; and volatility
of approximately 100% for both 2000 and 1999.

11.      STOCK OPTIONS (CONTINUED) :

         During 2000 and 1999, the Company did not incur any compensation cost
for the Plans under APB No. 25. Had the compensation cost for the Company's
compensation plans been determined consistent with SFAS No. 123, the Company's
net loss and net loss per common share for 2000 and 1999 would approximate the
pro forma amounts as shown below:

         The effects of applying SFAS No. 123 in this pro forma disclosure are
not indicative of future amounts. SFAS No. 123 does not apply to awards prior to
1995 and the Company anticipates making awards in the future under its
compensation plans.

12.      STOCK WARRANTS :

warrants expired unexercised.

         In 1996, the Company issued 35,000 warrants to an advisor in connection
with the Company's fundraising activities. These warrants enable the holder to
purchase shares of the Company's common stock at a price of $2.00 per share
through 2006. In 1997, the Company issued 75,000 additional warrants to this
advisor in connection with services related to a joint venture agreement. These
warrants enable the holder to purchase shares of the Company's Common Stock at a
price of $1.00 per share through 2007.

         In connection with the issuance of the Company's Series G preferred
stock in 1997, the Company issued 850,000 warrants to holders of the Series G
Preferred. These warrants enable the holders to purchase shares of the Company's
common stock at a price of $1.00 through August 2002. A total of 350,000 of
these warrants were exercised in 1999 and an additional 325,000 of these
warrants were exercised in 2000.

         In October 1996, the Company completed a transaction whereby it
borrowed a total of $1,000,000 in secured loans from a group of individuals. In
connection with these loans, the Company issued 200,000 warrants with a value of
approximately $200,000. The warrants enabled the holder to purchase shares of
the Company's common stock at a price of $1.00 through June 2000. A total of
100,000 of these warrants were exercised in 1997 and 50,000 were exercised in

the time of issuance. These warrants were exercised in 1998. The remaining
400,000 warrants were issued in connection with loans totaling $100,000 made to
the Company in November 1998. These warrants were exercisable for a period of
one year, at a price of $0.25 per share, which approximated the market price of
the Company's common stock at the time of issuance. These warrants were
exercised in 1999.

         In 1999, the Company issued a total of 60,000 warrants to three
separate individuals in connection with services rendered to the Company. The
exercise price of these warrants is based on the fair market value of the

share. These warrants are exercisable for a period of 5 years from the date of
issuance.

         In 2000, the Company issued a total of 10,000 warrants to an individual
in connection with services rendered to the Company. The exercise price of these
warrants is $0.80 per share and they were valued at $4,646 based on the fair
market value of the Company's common stock at the time of issuance. These
warrants are exercisable for a period of 5 years from the date of issuance.

14.      COMMITMENTS AND CONTINGENCIES:

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.

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, 62 Diamond Field Emission patents and patent applications were
assigned directly to the Company and the Company has agreed to pay a royalty fee
of 2% of future commercial revenues related to the patents received. The Company
has the right to offset one half of the costs of maintaining these patents
against any royalties due under the agreement. No payments have been made to, or
are due to, MCC under this agreement.

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. At present we are not using the technology developed
under this joint venture agreement in any manner and do not anticipate using
this technology in the future. It is unlikely that any future amounts will ever
be spent.

14.      COMMITMENTS AND CONTINGENCIES (CONTINUED):

Till Keesman Agreement

         In May 2000, the Company licensed 6 carbon nanotube patents from Till
Keesman in exchange for a payment of $250,000 payable in shares of the Company's
common stock. Under the terms of the agreement, the Company is obligated to pay
license fees equal to 50% of any royalties received by the Company related to
these patents. The company is allowed to offset certain expenses, up to a
maximum of $50,000 per year, against payments due under this agreement. The
agreement also contains provisions related to minimum license fee payments. If
the Company does not pay minimum additional license fees of $500,000 by May,
2002, the license will terminate at that point. If the Company does not pay
additional cumulative license fees of $1,000,000 (including any fees applied
toward the previously described minimum due in May 2002) by May 2004, the
license will terminate at that point. The Company is not obligated to make any
additional payments, but the license may terminate if these payments are not
made. Accordingly, the initial payment of $250,000 for the patents is being
amortized over a period of approximately two years.

Employment contracts

         The Company has entered into an employment agreement with its president
and chief operating officer. The agreement calls for an annual base salary of
$150,000 and for the Company to provide a vehicle for his use. The agreement can
be terminated by either party with or without cause with 30 days notice. If the
agreement is terminated by the Company without cause, the Company is obligated
to pay severance equal to nine months salary.

Research and Development commitments

         As of December 31, 2000, the Company was obligated to perform funded
research in the amount of approximately $582,000 on government contracts. The
cost of the research in 2001 is expected to approximate the revenue received for
the research.

Legal Proceedings

         On November 16, 2000, the former owner of Sign Builders of America,
Inc. filed suit against SI Diamond Technology, Inc and Sign Builders of America,
Inc. for alleged breech of the purchase agreement related to offsets the Company
took against the final note payment. The Company has filed a counterclaim
against the former owner for amounts due back to the Company as a result of
these offsets. The Company expects the ultimate resolution of this suit to have
no material impact on the consolidated financial statements. See Note 5.

     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 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 settled this lawsuit in 2000 in exchange for a payment of $28,000.

Legal Proceedings (cont.)

         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 claimed a breach of contract
related to $1 million of coating equipment that Plasmatron delivered in 1993,
prior to the Company's ownership of Plasmatron. 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 first two notes were
paid when due in 2000.

         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. In February 2001, the Company agreed
to participate in a settlement agreement whereby it would pay a total of
$150,000, of which $50,000 is due by June 1, 2001 and the balance of $100,000 is
in the form of a note due in July, 2003. See Note 5.

         The Company previously had a royalty agreement with Texas Digital
Systems, Inc. (TDS) which was terminated by TDS pursuant to the terms of the
agreement as of December 31, 1999. Under the terms of the agreement, TDS was
prohibited from using the Company's technology after the termination of the
agreement. The Company believed that TDS was continuing to ship products using
our technology and contacted TDS. TDS responded, in part, by filing suit against
the Company and EBT for breach of contract in the 272nd Judicial District Court
in Brazos County Texas on July 26, 2000. The Company was not served with notice
of this suit until December 5, 2000. It is the Company's view that the TDS claim
against the Company has little merit and that a significant reason that TDS
filed suit was to obtain venue in its home venue of Brazos County rather than in
the Company's home county of Travis County. The Company intends to vigorously
pursue its claim against TDS and seek damages and an injunction against TDS for
continuing to use the Company's technology in TDS products after the termination
of the agreement.

The Company and its subsidiaries are also defendants in various other lawsuits
related to the non-payment of invoices when due, or minor employment matters. 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. If
resolution of any of these suits results in a liability greater than that
recorded, it could have a material financial impact on us.

         The above lawsuits resulted in $118,000 and $200,000 charged to
operations in 2000 and 1999, respectively. A total of approximately $300,000 was
accrued at December 31, 2000.

14.      COMMITMENTS AND CONTINGENCIES (CONTINUED):

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 was
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. None of the
warrants that are potentially exercisable have been assigned any value as the
ultimate exercisability of the warrants is not determined at this point. The
Company had revenues of $2,160 in 2000 and no revenues in 1999 resulting from
this agreement.

         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 shares and all warrants issued under this
         agreement expire December 31, 2006.

15.      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, 2000 and 1999, 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.

16.      SIGNIFICANT CUSTOMERS :

         Accounts receivable - trade includes receivables from two major
customers, amounting to $97,120, and $1,974, at December 31, 2000 and 1999 ,
respectively. Net sales, to these two major customers amounted to $474,467 in
2000 and $38,025 in 1999.

17.      RETIREMENT PLAN :

         The Company sponsors a defined contribution 401k profit sharing plan.
No company contributions were made in either 2000 or 1999.

18.      RELATED PARTY TRANSACTIONS :

         In October 1998, EBT 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, the
agreement was modified to allow EBT to obtain additional 90 day extensions at a
cost of $12,500 for each extension. An additional $37,500 was paid for 3
additional extensions, bringing the total payments to $87,500. EBT can complete
the patent assignment agreement at any time by paying the remaining $112,500 due
on the initial payment.

         During 2000, the Company sold electronic display units to Dr. Zvi
Yaniv, the Company's President and Chief Operating Officer at a total price of
$22,500. This sales price approximated the Company's cost.

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

         Effective August 31, 1999, the Company purchased substantially all of
the assets and assumed certain liabilities of SBOA. 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:

         Total Purchase Price                                              $ 1,600,000
                                                                           ===========
</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 at December 31,
1999 to the $1,600,000 reflected above. The notes payable described above were
adjusted down at the same date to $250,000 from their initial amount of $450,000
as a result of the same purchase price adjustments. At the time of the due date
of the final note in September 2000, additional purchase priced adjustments
provided for in the agreement were calculated and offset against the payment due
at that time. As described in note 14, the seller has initiated a lawsuit in
connection with these offsets. Accordingly, the basis of the assets has not been
adjusted, pending resolution of that litigation.

         At December 31, 2000, as part of the review of its intangible assets
described in greater detail in Note 6, the Company determined that the Goodwill
and Covenant not to Compete received in this acquisition were impaired at that
date and the remaining net book value of $639,761 was charged to operations at
that time.

</TABLE>

         Although the chief operating decision maker does not use this segmental
financial information in evaluating performance, some segmental financial
information is furnished to the chief operating officer for review regarding
each subsidiary of the Company.

         The FEPET segment consists of the activities of FEPET and includes
license revenues and contract research revenues related to FEPET's technology.
In 2000, all FEPET revenues were contract research revenues. In 1999,
approximately 95% of FEPET's revenue came from license fees and the remaining
amount came from contract research services. The SBOA segment consists of the
activity of SBOA which is the manufacture and installation of custom signage,
including electronic, neon, static, and other types of signage. SBOA was
acquired in 1999 and the above segment information covers the four month period
from September 1, 1999 through December 31, 1999. The Company's EBT subsidiary
sells electronic display products, installs electronic display products on
customer premises under agreements to share in advertising revenue, sells
advertising on displays, and licenses its products or technology to others.
Virtually all EBT revenue in 1999 was from licensing technology. The majority of
EBT's revenue in 2000 was from the sale of advertising and the sale of
electronic display products. All other segments include the Company's general
overhead.

         The accounting policies applied by each of the segments are the same as
those used by the Company.

21.      RESEARCH AND DEVELOPMENT CONTRACTS :

         The Company makes significant expenditures for research and
development. On occasion, the Company may seek funding for a portion of its
research and development costs to reduce the cost of such expenditures to the
Company. The Company only seeks funding for projects that it already intended to
do, or for projects that would apply its technology for other uses in instances
where that application would allow the Company to achieve technical milestones
that were already part of its goals. The majority of the Company's funded
research has been from government contracts. Under government contracts, the
government has the right to utilize the results for its purposes and the Company
has the right to utilize the technology for commercial purposes. Generally, when
the Company contracts with other entities, the entity is also conducting its own
internal research related to application of the Company's technology to its
products and such expenditures by the entity may exceed the amount of funding
provided to the Company. Usually the entity has the right to license the
technology at the conclusion of the project, if they desire. The costs of a
particular research program may significantly exceed the funding received,
however since the research was part of planned research, these contracts
generally involve only nominal additional costs to the Company. For financial
statement purposes, the Company considers the cost of the contracts to be equal
to the revenue received.

The following schedule summarizes certain information with respect to research
and development contracts:

22.      SUBSEQUENT EVENTS :

         Through March 14, 2001, in exempt offerings under Regulation D of the
Securities Act of 1933, the Company issued a total of 1,178,284 shares of its
common stock for a total of $522,047.

         Effective January 2001, the Company entered into a contract with a
large Japanese display manufacturer to perform contract research related to the
Company's technology. A payment of $600,000 was received in January 2001.

         In January 2001, the Company paid off a short term note payable in the
amount of $125,000.

         As described in greater detail in Note 14, in February 2001, the
Company agreed to participate in a settlement agreement related to a lawsuit
whereby it would pay a total of $150,000, of which $50,000 is due by June 1,
2001 and the balance of $100,000 is in the form of a note due in July, 2003.
This settlement was accrued as of December 31, 2000.

ITEM 8.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
         FINANCIAL DISCLOSURE.

         On September 6, 2000, SI Diamond Technology, Inc. (the "Registrant")
was notified that WallaceSanders & Company had merged with McGladrey Pullen, LLP
and that WallaceSanders & Company would no longer be the auditor for the
Registrant. McGladrey & Pullen, LLP was appointed as the Registrant's new
auditor effective September 6, 2000. The Auditor's reports from WallaceSanders &
Company for the Registrant's past two fiscal years did not contain an adverse
opinion or a disclaimer of opinion, and were not qualified as to audit scope or
accounting principles. However, the auditor's report for the past two fiscal
years were modified regarding the uncertainty of the Registrant's ability to
continue as a going concern. The decision to engage McGladrey Pullen, LLP as the
successor to WallaceSanders & Company was recommended and approved by the
Registrant's Board of Directors. During 1998 and 1999 and the subsequent interim
period preceding the change, there have been no disagreements with
WallaceSanders & Company on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure.

             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

(1)      Directors who are also executives of SI Diamond are not listed in the
above table. They do not receive compensation as Directors. Refer to the Summary
Compensation Table for information concerning their compensation. Mr. Martin
resigned as a director on January 1, 2001.

(2)      All Directors receive $150 per board meeting or committee meeting
attended in person, and $50 per telephonic meeting. Reasonable expenses incurred
by each 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 SI Diamond may
grant stock options to any Director who is not a full time salaried employee of
the Company. On February 2, 2000, each Director at that time was granted a
discretionary grant of 30,000 options under this plan at a price of $2.75 per
share. On July 24, 2000, each Director at that time was granted an automatic
grant of 20,000 options under this plan at a price of $1.3438, with the
exception of Mr. Bailey who was granted 13,333 options. Under the terms of the
plan, Mr. Bailey's grant was prorated because of a partial year of service on
the Board. All grants in 2000 became exercisable in full on the date of the
grant.

         All of the 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

         The Company has entered into an employment agreement with its president
and chief operating officer. The agreement calls for an annual base salary of
$150,000 and for the Company to provide a vehicle for his use. The agreement can
be terminated by either party with or without cause with 30 days notice. If the
agreement is terminated by the Company without cause, the Company is obligated
to pay severance equal to nine months salary.

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         In October 1998, EBT 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, the
agreement was modified to allow EBT to obtain additional 90 day extensions at a
cost of $12,500 for each extension. An additional $37,500 was paid for 3
additional extensions, bringing the total payments to $87,500. EBT can complete
the patent assignment agreement at any time by paying the remaining $112,500 due
on the initial payment.

         During 2000, the Company sold electronic display units to Dr. Zvi
Yaniv, the Company's President and Chief Operating Officer at a total price of
$22,500. This sales price approximated the Company's cost.
