                       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. You can identify these statements by
the fact that they do not relate strictly to historical or current facts. 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 - will be
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-Q, 8-K, and 10-K 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 the Company. This discussion is provided as permitted by the Private
Securities Litigation Reform Act of 1995.

DFE PRODUCT DEVELOPMENT IS IN ITS EARLY STAGES AND THE OUTCOME IS UNCERTAIN

         Our Diamond Field Emission ("DFE") technology, and any products that
use this technology, will require significant additional development,
engineering, testing and investment prior to commercialization. Our leading
potential DFE product is a cathode, or light source, intended for use in a
display. If the cathode is successful, a display using this cathode is also a
possibility. The cathode or display may not be successfully developed. If either
of these products is developed, it may not be possible to produce these products
in significant quantities at a price that is competitive with other similar
products.

THERE ARE NO CURRENT DFE PRODUCT REVENUES

         We currently receive no revenue from any products related to our DFE
technology. The only revenues that we receive related to our DFE technology are
revenues for continued research on the technology. We may never receive product
revenues from the DFE technology.

OUR SUCCESS IS DEPENDENT ON OUR PRINCIPAL PRODUCTS

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

WE HAVE A HISTORY OF OPERATING LOSSES

         We have a history of operating losses and have never had a profitable
quarter or year. We have incurred operating losses as shown below:

                  YEAR ENDED DECEMBER 31                NET LOSS
                  ----------------------             -------------
                         1992                         ($1,630,978)
                         1993                         ($7,527,677)
                         1994                         ($7,255,420)
                         1995                        ($14,389,856)
                         1996                        ($13,709,006)
                         1997                         ($6,320,901)
                         1998                         ($3,557,548)


         We may continue to incur additional operating losses for an extended
period of time as we continue to develop products. We do, however, expect to be
profitable in 1999. We may not be profitable beyond 1999. Wallace Sanders &
Company, independent auditors of the Company, have expressed substantial doubt
as to our ability to continue as a going concern based on these accumulated
losses from operations. See "Independent Auditors' Report." We have funded our
operations to date primarily through the proceeds from the sale of our equity
securities. In order to continue our transition from a contract research and
development organization to an organization with ongoing operations, we
anticipate that substantial product development expenditures will continue to be
incurred.

WE HAVE FUTURE CAPITAL NEEDS AND THE SOURCE OF THAT FUNDING IS UNCERTAIN

         We expect to continue to incur substantial expenses for R&D, product
testing, production, manufacturing, product marketing, and administrative
overhead. The majority of R&D expenditures are for the development of our DFE
technology and our electronic billboard product. Some of our proposed products
may not be available for commercial sale or routine use for a period of one to
two years. Commercialization of our existing and proposed products will require
additional capital in excess of our current sources of funding. 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. At the present time we have
existing resources, including royalties receivable, to sustain ourselves for a
period of approximately 18 months from the date of this report at current
spending levels. 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 and through strategic partners and debt offerings.
We are also concentrating on raising revenue by seeking customers for our
electronic billboard product, which is currently under development.


                                     Page iii
<PAGE>

         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 and
raising additional funds through strategic partners and additional debt
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 the Company.

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

         The display industry is highly competitive and is characterized by
rapid technological change. Our existing and proposed products will compete with
other existing products and may compete against other developing technologies.
Development by others of new or improved products, processes or technologies may
reduce the size of potential markets for our products. There is no assurance
that other products, processes or technologies will not render our proposed
products obsolete or less competitive. Most of our competitors have greater
financial, managerial, distribution, and technical resources than us. 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.

WE HAVE TECHNOLOGIES SUBJECT TO LICENSES

         As a licensee of certain research technologies through various license
and assignment agreements with Microelectronics and Computer Technology
Corporation and DiaGasCrown, Inc., we have acquired rights to develop and
commercialize certain research technologies. In certain cases, agreements
require us 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. Each agreement is subject
to termination by either party, upon notice, in the event of certain defaults by
the other party. The payment of such royalties may adversely affect the future
profitability of the Company.

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 advance 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 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 currently have
a limited marketing organization and there is no assurance that we will be able
to successfully market our proposed products even if such products perform as
anticipated.

WE HAVE LIMITED MANUFACTURING CAPACITY AND EXPERIENCE

         We have no established commercial manufacturing facilities in the areas
in which we are conducting our principal research. 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 products. At the present time, we have no intention
of establishing a manufacturing facility. We are focusing our efforts on
licensing our technology to others for use in their manufacturing processes. We
intend to contract with a qualified manufacturer for assembly services related
to our electronic billboard product, which is currently under development. To
the extent that any of our other products require manufacturing facilities, we
intend to contract with a strategic partner or other qualified manufacturer.


                                      Page iv
<PAGE>

WE MAY NOT BE ABLE TO MARKET AND SELL OUR PRODUCTS

         We intend to establish and develop a sales organization to promote,
market, and sell our products. This may require significant additional
expenditures, management resources, and training time. There can be no assurance
that we will be able to establish a successful sales organization.

WE ARE DEPENDENT ON THE AVAILABILITY OF MATERIALS AND SUPPLIERS

         We anticipate that the materials to be used in producing our future
products will be 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 manufactured by the
Company or its strategic partners will be readily available. However, there is
no assurance that these materials will be available in the future, or if
available, will be procurable at prices favorable to the Company or its
strategic partners.

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 the Company reside in our key scientific
and technical personnel. This know-how and these processes are not readily
transferable to other scientific and technical personnel. The loss of the
services of key scientific, technical and managerial personnel could have a
material adverse effect on us.

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 any of our
proposed products or ultimately develop any marketable products.

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, have filed applications for, or have been licensed technology
under numerous patents, 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 the Company. 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, require disputed rights to be
licensed from third parties or require us to cease selling our products.
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.
Claims that our products infringe on the proprietary rights of others are more
likely to be asserted after commencement of commercial sales incorporating our
technology.


                                      Page v
<PAGE>

         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 all employees and most 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.

OUR REVENUES HAVE BEEN DEPENDENT ON GOVERNMENT CONTRACTS IN THE PAST

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

<TABLE>
<CAPTION>
                                           Revenues from           Percentage of
              Year Ended December 31       Gov. Contracts          Total Revenue
              ----------------------       ---------------         ------------- 
              <S>                          <C>                     <C>
                       1992                   $  930,000                  99%
                       1993                   $1,147,000                  89%
                       1994                   $  820,000                  41%
                       1995                   $1,009,000                  33%
                       1996                   $2,869,000                  50%
                       1997                   $  854,000                  24%
                       1998                   $        0                   0%
</TABLE>


         We currently have no significant commitment for any future government
funding and do not intend to seek any government funding unless it directly
relates to achievement of our strategic objectives. To the extent that we are
unable to obtain funding from alternate sources, this could adversely affect our
ability to continue to perform research and development on our proposed
products.

         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

YEAR 2000 ISSUES MAY EXPOSE US TO LIABILITY

         Some computers, software, and other equipment include programming code
in which calendar year data is abbreviated to only two digits. As a result of
this design decision, some of the systems could fail to operate or fail to
produce correct results if "00" is interpreted to mean 1900 rather than 2000.
These problems are widely expected to increase in frequency and severity as the
year 2000 approaches and are commonly referred to as the "Year 2000 Problem."

The Year 2000 Problem presents us potential risks including, but not limited to,
the following:

   -     Products sold to customers - We have had very limited product sales to
         customers and believe that all products sold to customers are Year 2000
         complaint. Our risk in this area is extremely limited.

   -     Internal Infrastructure - We have completed an internal evaluation and
         have determined that all of our internal systems will be Year 2000
         compliant well prior to the end of 1999. Our risk in this area is
         extremely limited.

   -     Suppliers/third party relationships - There is no assurance that our
         suppliers or other third parties that we rely on will resolve any or 
         all Year 2000 problems with their systems on a timely basis. Since we
         have no significant suppliers of product, we believe our risk is 
         limited in this area.

   -     External Infrastructure - We are dependent on other entities such as
         governmental units, utilities, banks, etc. that maintain an external
         infrastructure necessary for us to operate. Although we expect that 
         such entities are addressing and solving their Year 2000 problems, 
         there is no assurance that these problems will be addressed and solved
         on a timely basis.

WE ARE EXPOSED TO MATERIAL LITIGATION

         We have been sued by a former customer of Plasmatron for damages that
the former customer claims that it incurred as a result of the alleged failure
of the machine provided by Plasmatron to perform as intended. Various trade
creditors have also filed suit to collect unpaid trade amounts due. We expect
these items to be resolved with no material impact on our financial statements.
If we were to become subject to a judgment that exceeds our ability to pay, that
judgment could have a material impact on our financial condition and could
affect our ability to continue in existence.

ITEM 1. BUSINESS.

                            DESCRIPTION OF BUSINESS

GENERAL

         SI Diamond Technology, Inc., a Texas corporation (the "Company"), is
engaged in the development of products and services based principally on novel
applications of thin films and the application of display technologies. The
Company believes that microelectronic and other applications of diamond thin
film technology will play an important role in the electronics industry. The
Company's research is focused on identifying key applications of this
technology. Based on its research, the Company is currently engaged in the
development of products based on Diamond Field Emission ("DFE") technology and
the development of an electronic billboard and related electronic display
products based on existing technology. Electronic billboards and related
electronic display products would provide a market for the Company's Diamond
Field Emission Lamp product when completed. Management believes that the
Company's greatest growth opportunity lies in DFE products and the development
of an electronic billboard and related electronic display products.

         The Company was incorporated in Texas in 1987. The Company's directly
and indirectly owned subsidiaries are as follows:

         SI Diamond's business includes the development and commercialization of
electronic billboards and related electronic display products and the
development and commercialization of DFE products. The Company has also
conducted contract research and development primarily for United States
governmental agencies. The business efforts of the Company have arisen out of
the Company's interest in thin film materials, notably thin film diamond and
diamond-like carbon ("DLC"). These interests have led the Company into
microelectronics-related processes, thin film based DFE products, and electronic
billboards and related electronic display products.

         SI Diamond conducts its operations through its subsidiaries. EBT is
engaged in the development of an electronic billboard and related electronic
display products such as outdoor display devices for use in the fast food or
other industries. FEPET is conducting research on the DFE technology. Where
appropriate, the Company enters into collaborations with third parties as
discussed in greater detail under the heading "Technology Agreements" later in
this section.


                                     Page 1
<PAGE>

         The Company incurred $1,167,673 in 1998 and $605,105 in 1997 in 
research and development expenses. The Company's 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 one 
to two years. There is no assurance that the products will be successfully 
developed, produced in commercial quantities on a cost-effective basis, or 
marketed successfully.

BUSINESS GROUPS

         ELECTRONIC BILLBOARD TECHNOLOGY, INC. EBT was incorporated in January
1997 to focus on developing sun-readable display products for outdoor use. The
Company's primary product under development is an electronic billboard which
will enable the outdoor advertising industry to fully exploit the Internet and
information revolution by placing ads at any location at any time. The Company's
plans for the billboard and related products are discussed in greater detail in
the section entitled "Business Development Strategies" later in this report.

         FIELD EMISSION PICTURE ELEMENT TECHNOLOGY, INC. FEPET is developing the
Company's proprietary DFE technology for use in a Diamond Field Emission Lamp
("DFEL"). The DFEL is a unique, high brightness, multi-color light source
intended for use initially in outdoor billboards, indoor video walls, and
alphanumeric displays. The DFEL is a pixel, which is the basic unit or picture
element that makes up the image displayed on a video screen. The DFE 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. This technology when fully developed would be a natural step in
the improvement progression in the Company's electronic billboard and other
related electronic products. The Company's plans for this technology are
discussed in greater detail in the section entitled "Business Development
Strategies" later in this report.

         DIAMOND TECH ONE, INC. The Company sold the operating assets of DTO in
May 1998 for a total sales price of approximately $2.2 million. DTO provided
manufacturing and engineering services for the microelectronics and display
industries, and was engaged in the design and fabrication of high performance
copper-polyimide substrates, bonded and packaged high density assemblies, and
the highest quality gold, solder or compliant "bumped" wafers.

         During 1997, DTO successfully completed its transition from a research
facility to a repetitive manufacturing facility. DTO achieved ISO 9001
certification during 1997 and customer demand exceeded available capacity. Sales
growth was required for DTO to achieve break-even. This growth was dependent
upon substantial new capital investment in the form of facility upgrades and
additional equipment. The Company concluded that it would be better to sell DTO
and invest its limited resources in its remaining higher potential subsidiaries.

BUSINESS DEVELOPMENT STRATEGIES

         OVERALL. The Company is a technology company. The Company plans to
focus its efforts on research, product development, and the licensing of its
technology to others. The Company has no plans to establish any manufacturing
facilities in the immediate future. To the extent that the Company needs to
develop manufacturing capabilities, it intends to use manufacturing
partnerships, joint ventures, or arrange to have its products manufactured
through contract manufacturers.

         ELECTRONIC BILLBOARDS. The Company intends to market its electronic
billboard product to major national retailers for their use in conjunction with
their existing on-site signage. These billboards are expected to be smaller in
size than the full size billboards the Company is also developing. The Company
intends to sell, lease, or operate its billboards through joint venture
arrangements with these retailers. To facilitate its entry into this market, 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. Vision Mark and C&A agreed to represent the Company
with several major high profile retailers defined as "protected" customers by
the agreements.


                                     Page 2
<PAGE>

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

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

         The Company's billboard is based on a proprietary version of a mature
existing technology. The base 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, relative low cost compared
with competing technologies, and high reliability. The Company has built a proof
of concept, which clearly demonstrates high contrast, sunlight readability, and
video range speeds. As the Company's FEPET subsidiary continues to develop its
DFE technology, EBT expects to integrate the DFE technology in its electronic
billboard because of the advantages that it is expected to provide related to
cost and quality. EBT expects its electronic billboard product to be successful
regardless of the timing of the availability of the DFE technology provided by
FEPET.

         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 in the drive through process. The Company receives a
royalty on all units sold by TDS. In 1998, TDS shipped 518 of these units to a
major fast food chain. After extensive testing, the fast food chain ordered a
unit for the drive through lane of each of its corporate stores (approximately
500 locations), and made the product available to its franchisees, which
represent approximately 7,000 additional locations. TDS is also marketing the
product to other fast food chains.

         DFE PRODUCTS. The major short run focus of FEPET is the continued
development and commercialization of its DFE product. As soon as the product is
commercially viable, the Company plans to introduce it in its electronic
billboard product. In addition the Company would then target other large display
manufacturers that manufacture displays for such uses as sports arenas, video
walls, alphanumeric signs, etc. FEPET has completed Phase I of its collaborative
efforts with Diamond Pro-Shop Nomura Co., Ltd. ("DPN") that commenced in
September 1997 to develop a cathode using the Company's DFE technology. In
January 1999, DPN agreed to fund the Phase II development program. It is
anticipated that upon completion of the Phase II development program in early
2000, the product will move into the manufacturing stage. It is anticipated that
the product will be used in large screen display applications, video walls, and
the Company's electronic billboard products.


                                     Page 3
<PAGE>

The Company is also developing a new display technology, the HyFED. HyFED
combines the best properties of cathode ray tubes ("CRTs") and Field Emission
Displays ("FEDs") using the Company's proprietary diamond/carbon thin films. The
HyFED that the Company is developing is a hybrid of CRTs and FEDs. It is
anticipated 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 CRTs. In January 1999, the Company formed an
International Development Team to develop the first HyFED display. The
International Development Team is initially composed of six organizations - four
from Japan, one from Europe, and the Company. The International Development Team
expects to have a working four inch prototype of the HyFED by the last quarter
of 1999. Each member of the team is focusing on the development of a specific
portion of the first prototype and each member is funding their own portion of
the work. Upon completion of the first prototype, these team members will be
given the first opportunity to license the HyFED technology.

         LICENSING AGREEMENTS. The Company has an extensive patent portfolio 
that it has developed and acquired over the years. Licensing of this 
technology to major companies in the display industry is a critical part of 
the Company's overall strategic plan. In March 1999, the Company signed a 
license agreement with a large manufacturer of information and office 
products. Under the terms of this agreement, the Company will receive gross 
royalties of $5,555,556 no later than April 12, 1999 for a paid up worldwide 
non-exclusive license to certain of the Company's patents and patent 
applications. After foreign taxes associated with this payment, the Company 
will net $5,000,000. The Company expects to enter into other licensing 
agreements with other manufacturers in the future.

COMPETITION

         ELECTRONIC BILLBOARDS. The Company believes that the proprietary
version of the technology that the Company is planning to develop 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 and do not
           allow certain colors to be viewed in direct sunlight
   -     Incandescent bulbs that are high maintenance and result in poor 
           graphics
   -     Electromechanical systems that have poor image qualities
   -     Vacuum Fluorescent Displays ("VFD") which are used currently in
           large stadium displays, but are not considered cost effective for
           this application at the present time.

         The Company is unaware of any other organizations developing an
electronic billboard using a version of this technology. However, this is an
existing technology used in many applications. Competition from other
manufacturers could develop at any time.

         DFE PRODUCTS. The short term focus in DFE products is the development
of the DFEL to be used as the pixel light source in a large display. The light
source is the most vital and costly part of a large display, accounting for
approximately 25 - 30% of its cost. Since the pixel light source directly
equates to the visual quality and reliability of the display, the 
characteristics of the pixel light source are critical to a purchase decision.
Competition for the Company's DFEL will come from other technologies. Following
is a summary of some of those technologies and key differences.

LEDs have long lifetimes and low operating costs. However, they are high priced
initially and produce a grainy picture, which cannot be viewed in direct
sunlight. VFDs offer excellent picture quality and color, but they are extremely
expensive to install and operate. Electromechanical displays have poor image
quality and limited colors. Incandescent bulbs have high maintenance costs and
poor graphics. Liquid Crystal Displays ("LCD") are attractive because they have
a long lifetime and an existing manufacturing base. It is expected however that
the DFEL will provide wider viewing angles, a wider range of operating
temperatures and higher brightness.

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

                                     Page 4

TECHNOLOGY AGREEMENTS

         MCC. In 1998, the Company simplified its technology agreements with 
MCC, the Austin-based consortium of North American Electronics leaders. The 
Company previously licensed 144 patents and patent applications from MCC 
under an exclusive arrangement. This licensing agreement was amended in 1997 
and again in 1998 to directly transfer 62 of these patents and patent 
applications related to the DFE technology directly to the Company and return 
the remaining patents and patent applications to MCC. The Company is 
obligated to pay MCC a royalty of 2% of revenues related to transferred 
patents. The Company can offset certain pre-defined expenses against these 
royalty payments.

         DIAGASCROWN. In February 1995, the Company entered into a series of 
agreements with DGC. Under these agreements, the Company and DGC agreed to 
collaborate on the further development of DFE-related technology. The Company 
has the right to use the DGC technology on a royalty-free basis. All 
technology developed under the DGC collaboration is jointly owned by the 
Company and DGC, although DGC has agreed to assign its interest to the 
Company. Consequently, the Company will have the sole authority to sublicense 
the technology obtained under the collaboration, should it elect to do so. 
(See Note 11 to the Consolidated Financial Statements). The Company committed 
to perform $2.5 million in research and development in Russia through 
February 1997. According to its internal records, the Company spent 
approximately $2,000,000 on this research through December 31, 1998. Further 
spending in Russia has been halted since 1996, pending agreement as to the 
nature and amount of services to be performed in Russia for the remaining 
balance to be spent under the original agreement. It is not anticipated that 
any further research will be performed in Russia in the near future. The 
internal results achieved by the Company are far superior to those achieved 
through the collaborative efforts. The Company has not received a significant 
benefit for the money that has been spent in connection with this agreement. 
The Company has informed DGC that no further research will be performed in 
connection with this agreement unless payment is tied to the achievement of 
certain pre-defined milestones and goals.

         ADDVENT. In May 1995, the Company entered into the ADDVent joint 
venture agreement with another electronics manufacturer to develop a 10-inch 
field emission display under the Advanced Technology Program ("ATP") 
administered by the National Institute of Science and Technology ("NIST"). 
The ATP contract provided for expenditures of $7.0 million by the Company 
from 1995 through 1997. These expenditures were to be funded 49% by NIST. 
Under the ATP, the Company will own the rights to the technology, subject to 
the license rights of the United States government and the rights of its 
partner to own the high-voltage driver which it develops under the ATP and 
which its partner has agreed to supply the Company. The Company's right to 
its partner's driver shall be exclusive for a period of two years following 
acceptance by the Company of its partner's driver design. The Company manages 
this project and has made the majority of the expenditures under this 
program. As of December 31, 1998, the Company had completed its portion of 
the program, which resulted in the development of useable carbon films for 
use in display applications. These carbon films achieved certain 
specifications required in the display industry and are addressable, 
patternable, and have achieved the minimum emission site density required. 
The Company's joint venture participant has not yet completed the driver 
development.

PATENTS AND PROPRIETARY RIGHTS

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

         The Company owns 42 issued patents, three allowed patents, and has 
45 patent applications pending in the United States. The Company also has 
several patent applications in process. The patents, allowances and 
applications relate to the DFE technology and other technologies. In 
addition, there are foreign counterparts to certain United States patents and 
applications.
                                       
                                    Page 5
<PAGE>

         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 the Company's 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 the Company's 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 the 
Company fails to obtain patents for its technology, and is required to rely 
on unpatented proprietary technology, there is no assurance that the Company 
can protect its rights in such unpatented proprietary technology, or that 
others will not independently develop substantially equivalent proprietary 
products and techniques, or otherwise gain access to the Company's 
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, those of the Company. The scope and validity of these patents, the extent 
to which the Company 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 the Company's ability to market its products. 
Litigation concerning these or other patents could be protracted and 
expensive. If suit were brought against the Company for patent infringement, 
a challenge in the suit by the Company 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 the Company 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 the 
Company's interest in the affected products. Should the Company elect to 
manufacture or market these products without a license or a favorable 
determination as to the invalidity of these patents, damages could result 
which could be materially adverse to the Company. Further, failure to obtain 
a license could result in an injunction prohibiting the Company from 
manufacturing or selling the affected lines of products.

         The Company also relies 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 
the Company's trade secrets or disclose such technology or that the Company 
can meaningfully protect its rights to its unpatented trade secrets.

         The Company requires its 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 the Company. 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 
the exclusive property of the Company. There is no assurance, however, that 
these agreements will provide meaningful protection for the Company's trade 
secrets in the event of unauthorized use or disclosure of such information.

GOVERNMENT REGULATION

         The Company's products will be subject to extensive government 
regulation in the United States and in other countries. In order to produce 
and market its existing and proposed products, the Company 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. The Company 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. The Company does not believe that its DFE products will 
present any significant occupational risks to the operators of such 
equipment. In addition, the DFE 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 the Company and 
its products. Additionally, the Company's arrangements with its customers and 
affiliates may subject its products to export and import control regulations 
of the U.S. and other countries.

                                    Page 6
<PAGE>

         A portion of the Company's revenues have consisted of earnings under 
U.S. government contracts, although the Company received no such revenue in 
1998 and currently has no active grants. 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. The 
Company is, and in the future expects to be, audited by the government. The 
Company's ATP program is required to be audited in accordance with NIST 
standards. The Company expects the results of these audits to have no 
material impact on the Company.

EMPLOYEES

         As of March 15, 1999, the Company had 20 full-time employees, 
including three executive officers. Within the next twelve months, if 
business conditions support it, the Company expects to hire additional 
employees. The Company is not subject to any collective bargaining agreements 
and it considers its relations with its employees to be good.

ITEM 2. PROPERTIES

         The Company leases a 10,000 square foot facility in Austin for a 
monthly rental of approximately $7,000. The Company believes that this 
facility will be adequate for its anticipated research and development 
activities until additional products or alternative applications are 
developed. If and when such additional products or alternative applications 
are developed, the Company may be required to establish additional facilities 
or enter into manufacturing agreements with others.

ITEM 3. LEGAL PROCEEDINGS

         On May 20, 1996, Semi-Alloys Company, a former customer of 
Plasmatron, filed a complaint with the Supreme Court of the State of New 
York, County of Westchester. The complaint names Plasmatron, the Company and 
Westchester Fire Insurance Company as defendants. Semi-Alloys claims a breach 
of contract related to $1 million of coating equipment that Plasmatron 
delivered in 1993, prior to the Company's ownership of Plasmatron. 
Semi-Alloys claims the equipment does not perform as required under the 
contract. Semi-Alloys seeks to recover compensatory, consequential and 
incidental damages. The amount of this claim is to be determined at trial. A 
trial date has been set for August 1999. At this time the outcome cannot be 
predicted with any certainty and the potential liability, if any, is unknown. 
The Company believes it has meritorious defenses and intends to continue to 
vigorously defend this action.

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

         On August 18, 1998, KDF Electronic & Vacuum Services, Inc., a vendor 
of DTO, filed a complaint in the United Sates District Court for the Southern 
District of New York against the Company for unpaid debts of its subsidiary, 
Diamond Tech One, Inc. The Company was served with notice of this suit on 
October 14, 1998. All known amounts owed by DTO to KDF are recorded as 
liabilities of DTO in the consolidated financial statements of the Company. 
The amounts recorded as liabilities by DTO make up substantially all of the 
amounts claimed as due by KDF. No trial date has been set in this matter. 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 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. 
The Company contends that Aetna failed in its duty to mitigate damages and 
behaved in a reckless manner, which resulted in damages to the Company and 
its property. The Company intends to file a counterclaim against Aetna and 
its property manager for damages and the return of its security deposit. The 
Company believes that the ultimate resolution of this matter will not have a 
material impact on the consolidated financial statements of the Company.

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

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 1998.

         On March 18, 1999, the closing sale price for the common stock as 
reported on the NASDAQ system was $0.80. As of March 18, 1999, there were 
approximately 350 shareholders of record for the Company's common stock.

         The Company has never paid cash dividends on its common stock, nor 
does it have any plans to pay dividends. Its board of directors currently 
intends to invest future earnings, if any, to finance expansion of its 
business. Any payment of cash dividends in the future will be dependent upon 
the Company's earnings, financial condition, capital requirements, and other 
factors deemed relevant by its board of directors. It is unlikely that any 
dividends on the common stock will be paid in the foreseeable future.

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

         The following discussion should assist in understanding the 
Company's financial position and results of operations for the years ended 
December 31, 1998 and 1997. The Notes to the Consolidated Financial 
Statements of the Company included elsewhere in this report contain detailed 
information that should be referred to in conjunction with this discussion.
                                       
                                   OVERVIEW

         Throughout 1998 and 1997, the Company continued its efforts to move 
from a contract research and development organization toward commercial 
viability. The Company made the decision to sell the operating assets of its 
DTO subsidiary in May 1998 to focus on its remaining higher potential 
subsidiaries. DTO, while having excellent business prospects, required a 
substantial investment in facilities, equipment, and new employees to 
capitalize on these opportunities and achieve break-even status. The Company 
decided that it would be better to sell the DTO assets, use the proceeds to 
reduce debt, cut overhead, and focus on the development of its DFE and 
electronic display products. The Company had previously made the decision to 
close its Plasmatron facility in 1997. After the sale of the DTO assets the 
Company was able to focus on the development efforts at its remaining 
subsidiaries. The Company expects to continue these concentrated research and 
development efforts in 1999.
                                       
                             RESULTS OF OPERATIONS

         1998 COMPARED TO 1997. The Company earned $721,841 in revenues 
during 1998, as compared with $3,568,164 during 1997. Commercial sales, which 
accounted for all of 1998 revenues, were $2,714,086 in 1997. In 1998, the 
Company received revenues from DTO of $385,364, EBT of $192,246, and FEPET of 
$144,231. In 1997, the majority of the Company's revenues resulted from the 
manufacture and assembly of high-density electronic products by DTO and the 
production of equipment under contracts through the Company's Plasmatron 
subsidiary. DTO had revenues of approximately $1,390,000 in 1997 and 
Plasmatron had revenues of approximately $850,000 in 1997. The Company's 
FEPET subsidiary generated net commercial revenues of approximately $144,000 
in 1998 and $416,000 in 1997. The 1998 revenues were primarily the result of 
the sale of research services and of selected equipment designed and 
constructed by FEPET in the research process. The 1997 FEPET revenues were 
primarily the result of revenue related to future licensing granted in 
connection with a joint venture agreement. The Company's EBT subsidiary had 
commercial revenues of approximately $192,000 in 1998 and $58,000 in 1997. 
Approximately $131,000 of EBT's 1998 revenues resulted from its royalty 
agreement with TDS. The balance of 1998 revenues and all 1997 revenues were 
the result of the sale of certain developmental products. The Company had no 
contract research revenues for 1998 as compared to $854,078 for 1997. The 
reduced contract research revenue resulted from the completion of the 
Company's portion of the National Institute of Science and Technology 
("NIST") contract in 1997. The Company has not applied for any additional 
research grants, and expects no contract research revenues in the immediate 
future. The Company may seek additional research grants in the future if such 
grants are directly related to projects that the Company is already working 
on in conjunction with its strategic objectives.

         The Company had no revenue backlog at December 31, 1998. For 
purposes of calculating its backlog, the Company includes only those 
verifiable commitments that exist as of the backlog date. Under the Company's 
agreement with TDS, the Company receives a royalty when TDS ships a product. 
No amounts related to this agreement are included in the Company's backlog at 
December 31, 1998. During the period from June 1998, when TDS began shipments 
under the agreement, through December 31, 1998, the Company received revenues 
of approximately $131,000 under the agreement. During that time period TDS 
received an order from a major fast food chain for 500 units to enable the 
chain to install a unit at each of its corporate-owned stores. Substantially 
all of those units were shipped in 1998. The chain is also making the unit 
available to all of its franchisees, which number approximately 7,000 in the 
U.S. alone. TDS shipped approximately 50 units to franchisees in 1998. If all 
franchisees ordered one unit for each additional U.S location, it would 
result in the Company receiving between $1,750,000 and $2,100,000 in future 
royalty payments. In January 1999, the Company received funding of $225,000 
from a joint venture partner for a development project. This will be 
recognized as revenue over the term of the project, which the Company expects 
to be completed in 1999. At December 31, 1997, the Company had a commercial 
backlog of approximately $344,000, consisting entirely of customer orders at 
DTO.

                                    Page 10
<PAGE>

         For 1998, the Company's costs of sales were $1,592,225, resulting in 
a negative margin of 121% as compared with $4,388,747 and a negative margin 
of 23% during 1997. This decrease in margin resulted primarily from the 
Company's DTO subsidiary. DTO's average monthly revenue decreased in the 
months preceding the sale in 1998, while its cost structure was kept in place 
to keep the organization intact and its capacity at its previous level for 
prospective buyers. The Company had negative margins because its DTO 
subsidiary operated significantly below its facility capacity for both 
periods. The Company expects margins to improve in 1999 as a result of the 
sale of its DTO operations. The Company expects all products introduced in 
the future to have positive margins since it operates no manufacturing 
facility and therefore does not have the fixed overhead associated with such 
a facility.

         The Company's selling, general and administrative expenses decreased 
from $3,790,072 in 1997 to $2,149,018 in 1998. This decrease is primarily the 
result of the Company's efforts to minimize overhead and the elimination of 
the selling, general, and administrative expense associated with the 
operation of the DTO facility. Company sponsored research and development 
expenses increased in 1998 to $1,167,673 from $605,105 in 1997. The level of 
research activity was similar in the two years; however a portion of the 
Company's research activity in 1997 was reimbursed under the Company's NIST 
grant. The Company expects to incur substantial expenses in support of 
additional research and development activities related to the commercial 
development of its DFE and electronic display technologies. The Company has 
not applied for additional government grants at the present time and will not 
do so unless those grants are specifically related to activities the Company 
is already pursuing to accomplish strategic objectives.

         The gain on disposal of assets of $771,515 in 1998 resulted 
primarily from the sale of the operating assets of DTO in May 1998 for a 
total sale price of approximately $2.2 million. The loss on disposal of 
assets of $517,144 in 1997 resulted primarily from the sale of excess 
equipment. The 1997 loss on disposal of assets also includes a loss of 
$110,845 as a result of the abandonment of certain leasehold improvements 
when the Company combined its operations in Austin, Texas into one facility. 
In 1997, the Company recorded a loss on impairment of assets of $480,164 as a 
result of its decision to liquidate Plasmatron. This loss was the result of 
writing off certain inventory and the costs in excess of the fair market 
value of assets acquired related to the original acquisition of Plasmatron.

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

         The Company's cash position remained virtually unchanged between 
December 31, 1998 and 1997. At December 31, 1998, the Company had cash and 
cash equivalents in the amount of $2,636 as compared with cash and cash 
equivalents of $1,000 at December 31, 1997. Net cash used by operating 
activities was $3,536,784 for 1998 compared to $4,249,556 for 1997. The 
decrease in the requirement for cash was primarily the result of the reduced 
net loss from 1998 to 1997.

         Cash provided by investing activities for 1998 was $2,028,948 as 
compared to $220,845 for 1997. The increased cash provided by investing 
activities in 1998 was the result of proceeds from the sale of the operating 
assets of DTO, offset by minor capital expenditures. Only equipment with 
general alternative uses has been capitalized. Certain other specialized 
equipment has been expensed as research and development. No material 
commitments exist as of December 31, 1998 for future purchases of capital 
assets.

                                    Page 11
<PAGE>

         Throughout 1997 and 1998, the Company has continued to raise 
additional funds through equity and debt funding to finance its operating 
losses. The net cash provided by financing activities decreased from 
$4,013,421 in 1997 to $1,509,472 in 1998. As a result of its reduced 
operating loss and the proceeds from the sale of DTO, the Company had less of 
a need for additional financing. Based on the developmental stages of the 
Company's technology, additional financing will be necessary in the future. 
If all of the Company's warrants that were outstanding as of December 31, 
1998, and have not yet expired in 1999, were exercised, the Company would 
collect proceeds of approximately $2.3 million. (See Note 9 to the 
Consolidated Financial Statements.) Proceeds from the exercise of warrants 
totaled $90,000 in 1998 and $100,000 in 1997. Given the current price of the 
Company's common stock, it is unlikely that all warrants would be exercised 
in the near future. Approximately one half of the potential proceeds from 
warrants involve warrants priced significantly above the current market 
price. The Company may also receive proceeds from the exercise of stock 
options. If all currently vested options that have an exercise price below 
the market price of the Company's stock as of March 18, 1999 were exercised, 
the Company would receive proceeds of approximately $1.3 million.

         Following is a summary of debt and equity proceeds that the Company 
has received from January 1, 1996 through the date of this filing:

Series E Preferred Stock

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

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

         During 1998, 168 shares of the Series E preferred stock were 
converted into 6,893,526 shares of common stock and 28 shares of the Series E 
preferred stock were redeemed for cash of $332,011. During 1997, 418 shares 
of the Series E preferred stock were converted into 5,542,941 shares of 
common stock and 32 shares of the Series E preferred stock were redeemed for 
cash of $368,795. As of December 31, 1998, all shares of the Series E 
preferred stock had been converted to common stock or redeemed for cash. 
Cumulatively, 14,676,061 shares of the Company's common stock were issued 
upon conversion of 1,128 shares of the Series E preferred stock.

DTO Notes

         In October 1996, DTO, a subsidiary of the Company, issued notes 
payable totaling $1,000,000. These notes bore interest at a rate of 15%, 
payable quarterly. The principal balance was due June 1, 1997. In connection 
with these notes, the Company also issued 200,000 warrants enabling the 
holder to purchase shares of the Company's common stock at a price of $1.00 
per share. 100,000 of these warrants were exercised in 1997. The notes were 
collateralized by the assets of DTO and guaranteed by the Company.

8% Convertible Debenture

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

                                    Page 12
<PAGE>

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

Series F Preferred Stock

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

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

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

Series G Preferred Stock

     From June 1997 through August 1997, through an exempt offering under 
Regulation D of the Securities Act of 1933, the Company issued 1,700 shares 
of its Series G preferred stock. The offering provided 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. Each share of Series G preferred stock is 
convertible into shares of common stock as determined by dividing the 
original issue price of the Series G preferred stock, plus an accretion 
amount equal to 10% of the issue price per annum, by the conversion price. 
The conversion price is fixed at a rate of $1.00 per share. The Series G 
preferred stock bears no dividends and holders of the Series G preferred 
stock are entitled to vote on all matters submitted to a vote of the 
stockholders on an "as if converted" basis.

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

     During 1998, 100 shares of Series G Preferred stock were converted into 
110,000 shares of common stock.

October 1997 Offering

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

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

1998 Private Placements

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

MCC Settlement

         During 1998, the Company issued 500,000 shares of the Company's 
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 11 to the 
Consolidated Financial Statements. Based on the market price of the Company's 
stock at the time, these shares were valued at $100,000. In 1997 the Company 
also issued 340,717 shares of the Company's 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.

December 1997 Notes

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

Other 1997 Shares

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

1998 Notes

         During 1998, the Company issued a total of $1,005,000 of notes 
payable to investors that were convertible into shares of the Company's 
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 the Company's 
common stock in 1998 and $705,000 were converted into shares of the Company's 
common stock in February 1999. The remaining $100,000 of these notes are 
payable to the Company's CEO and have not been converted to common stock. The 
Company also issued notes payable totaling $260,000 which are not convertible 
into the Company's common stock. These notes were short-term notes bearing 
interest at a rate of 15% and secured by all assets of the Company. The 
Company also issued $100,000 of 90 day notes payable bearing interest at a 
rate of 15%, and secured by all assets of the Company, that were accompanied 
by warrants enabling the holders to purchase a total of 400,000 shares of the 
Company's common stock at $0.25 per share, which approximated market at the 
time of the loans.

1999 Notes

         In January and February 1999, the Company 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 the common stock of the Company at rates 
ranging from $0.30 to $0.40 per share. These conversion rates approximated 
the market price of the Company's 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.

         The principal source of the Company's liquidity has been funds 
received from exempt offerings of common and preferred stock. The Company may 
receive additional funds from the exercise of warrants, although there is no 
assurance that such warrants will be exercised. In the event that the Company 
needs additional funds, the Company may seek to sell additional debt or 
equity securities. The Company may seek to increase its liquidity through 
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 
be dependent upon the viability of its products and their acceptance in the 
marketplace, and its ability to obtain additional debt or equity financings 
in the future. Wallace Sanders & Co., independent auditors of the Company, 
expressed substantial doubt as to the ability of the Company to continue as a 
going concern based on accumulated losses from operations. See "Independent 
Auditors' Report."
                                       
                                    OUTLOOK

         As a result of the royalty agreement signed in March 1999, it is 
anticipated that the Company will be profitable in 1999 as it continues to 
fund the development of its DFE technology and its electronic billboard and 
related electronic display products. There can be no assurance that the 
Company will be profitable in the future. Full commercial development of the 
Company's DFE technology and electronic billboard and related electronic 
display products may require additional funds that may not be available at 
terms acceptable to the Company.

                                    Page 15

         The Company has developed a plan to allow it to maintain operations 
until the Company is able to sustain itself on its own revenue. At the 
present time the Company has the existing resources, including royalties 
receivable to sustain it for a period of approximately 18 months from the 
date of this report at current spending levels. The plan is primarily 
dependent on raising funds through the licensing of its technology and 
through strategic partners and debt offerings. The Company is also 
concentrating on raising revenue by seeking customers for its electronic 
billboard product, which is currently under development. Management believes 
that it has the ability to continue to raise additional funding, if 
necessary, to enable it to continue operations until its 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. The Company's plan is primarily dependent on 
increasing revenues and raising additional funds through strategic partners 
and additional debt offerings. If adequate funds are not available from 
operations, or additional sources of financing, the Company may have to 
eliminate, or reduce substantially, expenditures for research and 
development, testing and production of its products, or obtain funds through 
arrangements with other entities that may require the Company to relinquish 
rights to certain of its technologies or products. Such results would 
materially and adversely affect the Company.

     The Company has determined that the Year 2000 Issue will have an 
immaterial effect on the Company. The Year 2000 Issue is the result of 
computer programs being written using two digits rather than four to define 
the applicable year. Any of the Company's computer programs that have 
date-sensitive software may recognize a date using "00" as the year 1900 
rather than the year 2000. This could result in a system failure or 
miscalculations causing disruptions of operations, including, a temporary 
inability to process transactions, send invoices, or engage in similar normal 
business activities.

     Based on a recent assessment, the Company determined that it will be 
required to modify or replace portions of its software so that its computer 
systems will properly utilize dates beyond December 31, 1999. All of this 
software is prepackaged software that was purchased from outside vendors. 
These vendors all have upgrades available which correct the Year 2000 Issue. 
The Company plans to purchase the upgraded software, where required, in early 
1999 to insure adequate time for implementation. The cost of these upgrades 
is expected to be no greater than $20,000 and it is not expected to have a 
material effect on the operations of the Company. If such upgrades are not 
installed on a timely basis, the Year 2000 Issue could have a material impact 
on the operations of the Company.

     The Company has determined that it is not vulnerable to a third party's 
failure to remediate its own Year 2000 Issues since it has no significant 
suppliers or large customers. The Company has also determined that it has no 
exposure to contingencies related to the Year 2000 Issue for the products it 
has sold. The Company is ensuring that all products currently under 
development by the Company will be Year 2000 compliant prior to the sale of 
such products.

     This assessment is based on the present circumstances of the Company in 
which the Company has virtually no customers and no significant suppliers. In 
this scenario, the Company's Year 2000 risk is virtually non-existent. If the 
Company's business plan is successful and it is able to develop and sell 
products, the Company may become subject to Year 2000 risk related to third 
parties. The Company intends to assess the risk associated with third party 
remediation of the Year 2000 Issues at the time that it enters into any 
significant contracts or relationships with third parties and to develop a 
contingency plan at that time if necessary.
                                       
                            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 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 as of December 31, 1998 and 1997, 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, 1998 and 
1997, 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 and preferred stock to fund its 
operations and has experienced operating losses. The Company believes that 
its success in reaching profitability will be dependent upon the viability of 
its products and their acceptance in the marketplace, and its ability to 
obtain additional debt or equity financings in the future. As of February 15, 
1999, the Company has not yet achieved profitability, has a working capital 
deficit and must obtain additional financing to fund its ongoing operations. 
As a result, there is substantial doubt about 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.

               SI DIAMOND TECHNOLOGY, INC. AND SUBSIDIARIES

                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   ORGANIZATION AND OPERATIONS:

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

     As indicated in the accompanying consolidated statements of operations, 
the Company experienced operating losses in 1998 and 1997. The Company 
completed its initial public offering in 1993. Through February 1999, in a 
series of offerings, the Company has raised proceeds of approximately $52.1 
million, net of issuance costs (See Note 7). The Company is seeking strategic 
partners to inject capital to enable the commercialization of several of its 
technologies and fund a portion of the ongoing operations and development 
cost. To the extent that it is unable to raise sufficient funds through 
strategic partners, the Company may seek additional funds through the equity 
markets. There is no assurance that such strategic partners will be 
available, that funds will be available in the equity markets, or that 
commercialization will result in income from operations. Management believes 
it will be able to secure additional funding, if need be, to allow the 
Company to continue operations until an agreement can be finalized with a 
strategic partner or additional equity can be raised. Full commercial 
development of the Company's DFE technology may require additional funds that 
may not be available at terms acceptable to the Company.

     The principal source of the Company's liquidity has been from the funds 
received from exempt offerings of common and preferred stock. 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, their acceptance in the marketplace, and its 
ability to obtain additional debt or equity financings in the future.

     A portion of the Company's research and development has been funded 
through the sponsorship of agencies of the U.S. Government. The Company 
currently has no funded research projects from the U.S. Government and is 
currently not seeking any such grants. Under the present circumstances, all 
research and development performed is being internally funded by the Company 
or through joint venture partners. The Company has substantially reduced the 
amount being spent on research and development until such time as new grants 
are obtained or additional funding becomes available.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of consolidation

     The accompanying consolidated financial statements include the accounts 
of the Company and its wholly-owned subsidiaries, Diamond Tech One, Inc. 
("DTO"), Electronic Billboard Technology, Inc. ("EBT"), SDI Acquisition Corp. 
("SDI"), Plasmatron Coatings and Systems, Inc. ("Plasmatron"), SIDT Coatings, 
Inc. ("Coatings"), and Northlight Displays, Inc.  ("Northlight"), and its

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

Contract revenues and technology rights

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

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.

Accounts receivable

     The Company sells products and services on credit primarily to large 
U.S. based corporations and governmental agencies, although in some instances 
it may ship products to Asia or Europe. It is the Company's policy to record 
reserves for potential credit losses. Since inception, the Company has 
experienced minimal losses. The Company has no reserve for potential credit 
losses at either December 31, 1998 or 1997 and does not consider any such 
reserve necessary.

Inventories

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

Property, plant and equipment

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

Intangible assets

     The Company has applied to obtain certain United States patents, which 
are currently pending. Certain patent costs, which consist primarily of legal 
fees, have been capitalized and will be amortized using the straight-line 
method over the useful lives of the patents (5 years), if approved. If such 
patents are rejected, the costs will be charged to expense at the date of 
rejection. The Company wrote off the costs associated with certain patents no 
longer expected to have value to the Company as well as related liabilities. 
This write off had no material impact on expense in either 1998 or 1997. The 
majority of patent costs are expensed as incurred.

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

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

     In connection with this policy, and as the result of the shut-down of 
the Plasmatron operations in the third quarter of 1997, the Company wrote off 
the costs in excess of fair value of assets acquired related to the purchase 
of Plasmatron. These costs were being amortized using the straight-line 
method over an estimated life of 7.5 years and had a net book value of 
approximately $224,000 at the time they were written off.

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.

Preferred stock dividends

     The Series E and F preferred stocks contain a provision (See Note 7) 
that allows the preferred shareholder to convert their preferred shares to 
common stock at a discount to the market value of the stock. The amount of 
this discount is treated as a dividend to the preferred shareholders. In 
addition, the Series E preferred stock bears an 8% accretion payable in 
common stock and the Series F preferred stock bears a 4% accretion payable in 
common stock, payable at the date of conversion at the same price as the 
common shares being received. The Company's Series G Preferred stock bears a 
10% accretion payable in common stock at the date of conversion. All 
accretions paid in common stock or payable in common stock if the shares were 
converted as of December 31, 1998 and 1997, respectively, have been treated 
as preferred dividends. The amount treated as a dividend in 1998 related to 
the accretion and the discount was $36,142, $53,815, and $165,000, 
respectively for the Series E, Series F, and Series G preferred stocks. The 
amount treated as a dividend in 1997 related to the accretion and the 
discount was $535,758, $178,306, and $81,425, respectively for the Series E, 
Series F, and Series G preferred stocks.

Loss per common share

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

In 1998 and 1997, the Company had various amounts of preferred shares, common 
stock options and warrants outstanding during the years which were not 
included in the diluted loss per share calculation because they would have 
been antidilutive. As of December 31, 1998 and 1997, the Company had 1,700 
and 3,077 preferred shares outstanding, respectively, 4,227,397 and 2,834,703 
options outstanding, respectively, and 2,695,379 and 6,733,581 warrants 
outstanding, respectively.

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.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

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.

Fair value of financial instruments

     The Company's financial instruments as defined by SFAS No. 107, 
"Disclosures about Fair Value of Financial Instruments," include cash and 
cash equivalents, restricted cash, accounts receivable, notes receivable, 
accounts payable, accrued liabilities, notes payable, and capital lease 
obligations. All financial instruments are accounted for on an historical 
cost basis, which approximates fair value at December 31, 1998 and 1997.

New accounting standards

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

4.   LEASE OBLIGATIONS:

     The Company leases various facilities and equipment under operating 
lease agreements having terms expiring at various dates through 2003. Rental 
expense was $252,829 and $477,636 for the years ended December 31, 1998 and 
1997, respectively.

     Future minimum lease payments under operating leases that have initial 
or remaining noncancelable lease terms in excess of one year at December 31, 
1998, were as follows:

</TABLE>

     At December 31, 1997 assets acquired under a capital lease agreement of 
$733,688 were included in plant and equipment and accumulated amortization of 
$415,757 was also included in accumulated depreciation. Payments under the 
capital lease agreement were completed in 1997 and all equipment under this 
lease was transferred to the Company. This equipment was sold as part of the 
sale of the assets of DTO in 1998. Also in 1998, the lease on the property 
previously occupied by the Company was transferred to the purchaser of the 
assets of DTO at the time of the sale of DTO's assets.

5. BANK LINE OF CREDIT AND NOTES PAYABLE :

     During 1997, the Company had a bank line of credit that allowed for 
borrowings up to $500,000. Borrowings under the line of credit bore interest 
at the bank's floating rate, which approximated 10% at that time. The line 
of credit was secured by the assets of DTO and guaranteed by the parent 
Company. The line of credit expired in 1997 and was not renewed.

     Total interest expense for all debt was approximately $327,000 and 
$357,000 for 1998 and 1997, respectively.

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

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

      Included in the notes payable to investors are notes totaling $705,000 
which are convertible into the Company's common stock at the option of the 
lender. Of the notes that are convertible into the Company's common stock, 
$650,000 are convertible at a price of $0.25 per share and $55,000 are 
convertible at price of $0.20 per share, which approximated the market price 
of the stock at the time that the loans were made. These investors are also 
shareholders of the Company, although none would be classified as affiliates 
either by virtue of the number of shares owned or other relationships with 
the Company. In February 1999, these notes were converted to shares of the 
Company's common stock (see Note 15). The notes payable to the Company's CEO 
are also convertible into the Company's common stock at a rate of $0.25 per 
share.

     As of December 31, 1998, the Company had net operating loss 
carryforwards of approximately $51 million that expire from 2006 through 
2013, and are available to offset future taxable income. Additionally, the 
Company has tax credit carryforwards related to research and development 
expenditures of approximately $478,000 that expire through 2011. The Company 
completed its IPO in 1993, which effected an ownership change under Internal 
Revenue Code Section 382. The IPO and subsequent stock issuances may limit 
the Company's ability to utilize its net operating loss carryforwards and 
research and experimentation credits generated before the change in ownership.

Series A

     The Company had 100 shares of its Series A convertible preferred stock 
issued and outstanding as of December 31, 1998 and 1997. The Series A 
preferred stock is noncumulative. It has a liquidation preference of $1,000 
per share, is convertible into 1,252.75 shares of common stock per share and 
is entitled to vote on all matters submitted to a vote of the shareholders on 
an "as if converted" basis. The Series A preferred stock shall also share 
equally and simultaneously in any distribution to common shareholders after 
the liquidation preference has been paid.

Series C

     There are currently no outstanding shares of the Series C preferred 
stock; however, 75,000 shares were authorized for issuance pursuant to 
outstanding Series C warrants. These warrants to purchase Series C preferred 
stock expired on February 9, 1998. The Company has no plans to issue any 
Series C Preferred stock.

Series E

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

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

     In March 1997, the Company closed an exempt offering under Regulation D 
of the Securities Act of 1933 for 1,700 shares of its Series F convertible 
preferred stock. The Company received net proceeds of $1,527,500, which 
represented gross proceeds of $1,700,000 less expenses of $172,500. Each 
share has a liquidation preference of $1,000 plus 4% per annum from the date

price of the Series F preferred stock, plus an accretion amount equal to 4 % 
of the issue price per annum, by the conversion price. The conversion price 
was the lesser of $1.75 or 80% of the 10 day average closing bid price prior 
to the conversion date. The Series F preferred stock bears no dividends and 
holders of the Series F preferred stock have no voting power except in 
certain circumstances pursuant to Texas state law.

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

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

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.

7.   CAPITAL STOCK (CONTINUED):

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

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

     During 1998, 100 shares of Series G Preferred stock were converted into 
110,000 shares of common stock.

Subsidiary Preferred Stock

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

Common Stock

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

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

7.   CAPITAL STOCK (CONTINUED):

     In 1998, the Company issued 3,916,296 shares of restricted common stock 
and received cash proceeds of $713,236 in connection with private placements 
of the Company's common stock in exempt offerings under Regulation D of the 
Securities act of 1933. The shares were issued at prices approximating the 
market price of the stock at the time of the offerings. A registration 
statement covering these shares was declared effective June 18, 1998.

     In 1997 the Company issued 340,717 shares of the Company's common stock 
to MCC to pay the remaining balance due on a services agreement entered into 
in April 1995. The remaining principal and interest due under the agreement

minimum royalty payment also described in Note 11. In addition, the Company 
issued 239,275 shares of the Company's common stock in 1997 to various trade

connection with this transaction.

8.    STOCK OPTIONS:

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

     In March 1992, the shareholders of the Company approved the 1992 
Employees Stock Option Plan (the "1992 Employees Plan") for purposes of 
granting incentive or non-qualified stock options. The 1992 Employees Plan 
was amended in July 1996 by the shareholders of the Company to reserve up to 
3,000,000 shares of common stock for issuance to certain officers and key 
employees. The 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 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, 
1998, 191,834 shares remained available for grant under the 1992 Employees 
Plan.

     In July 1997, the Company's Board of Directors passed a resolution that 
changed the option exercise price of certain options previously granted under 
the 1992 Employees Plan. A total of 418,688 options were repriced. The 
Company reduced the exercise price to $2.00 for 25% of all options priced 
above $2.00 for all persons employed by the Company at the time of the 
repricing. The original exercise price of these options ranged from $3.00 to 
$4.00. The market price of the Company's common stock at the time of 
repricing was $1.125 per share, or approximately 44% below the new exercise 
price of the stock.

8.    STOCK OPTIONS (CONTINUED):

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

     In 1995, the Company awarded 153,000 non-qualified options to purchase 
its common stock under the 1992 Employees Plan to 26 employees. The options 
vested over a period of four years and when granted were exercisable at a 
price of $4.94 per share which was below the market price of the Company's 
common stock at the time of the grant. Unearned compensation was recorded and 
was shown as a separate component of stockholder's equity. The unearned 
compensation was amortized over the remaining term of the vesting periods of 
the options. Compensation expense of $8,630 was recognized in 1997 related to 
these issuances. Unearned compensation of $20,896 related to options canceled 
during 1997 was reversed to additional paid in capital in 1997. As of 
December 31, 1998 and 1997, no unearned compensation remained.

</TABLE>


     In May 1998, the Board of Directors of the Company established the 1998 
Officers and Directors' Stock Option Plan and reserved a total of 1,200,000 
shares for issuance under the Plan. A total of 750,000 options, 150,000 for 
each outside director, were granted in May 1998 and an additional 450,000 
options, 150,000 for each executive officer, were granted in July 1998. All 
1,200,000 options are exercisable at a price of $0.375 per share. At the time 
of both grants, the market price of the Company's common stock was 
approximately $0.25 per share, or approximately 33% below the exercise price.

     The fair value of each stock option granted in 1998 and 1997 is 
estimated on the date of grant using the Black-Scholes option pricing-model 
with the following weighted-average assumptions: no dividend yield for 1998 
and 1997; risk-free interest rate of 5.0% and 6.50% for 1998 and 1997, 
respectively; the expected lives of the options are five years for 1998 and 
1997; and volatility of approximately 100% for 1998 and 56% for 1997.

The following table summarizes information about stock options outstanding 
and exercisable under all three plans at December 31, 1997:

Vision Mark Agreement

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

conditions. At such time as the Company has received cumulative revenue from 
protected customers of $10 million and for each cumulative increment of 
$10,000,000 thereafter, C&A has the right to purchase 250,000 shares of the 
Company's common stock at a discount of 50% to the market price of the common 
stock when each $10 million increment is reached. In addition, C&A has the 
right to purchase an additional 2,300,000 shares of the Company's common 
stock at a 50% discount to the current market price of the stock when 
cumulative revenue from protected customers reaches $100 million and an 
additional 2,300,000 shares under the same terms when cumulative revenue 
reaches $200 million. Finally, if revenue in any annual period ending on each 
anniversary date of the agreement exceeds $10 million, then C&A has the right 
to purchase 200,000 additional shares under the following terms. If revenue 
from protected customers is equal to or greater than 25% of consolidated SI 
Diamond revenue, than C&A can purchase an additional 100,000 shares at a 25% 
discount to the market price at that time and up to another 100,000 shares at 
a discount to the current market price equal to the percentage of revenue 
that protected customers represent of total revenue, to a maximum of 50%. The 
maximum amount of shares that can be purchased under all warrants issued to 
Vision Mark and C&A under the agreements is 9,700,000. All warrants expire 
December 31, 2006.

11.  COMMITMENTS AND CONTINGENCIES (CONTINUED):

Agreements with MCC

     The Company entered into an agreement in 1994 with Microelectronics and 
Computer Technology Corporation ("MCC") that was amended on several 
subsequent occasions to cross license and pool technologies. As part of this 
relationship with MCC, the Company acquired non-exclusive licenses to 144 MCC 
patents and other related technology. Under the license, the Company was 
obligated to pay MCC a cumulative minimum royalty of $500,000 by December 31, 
1997 and $1,000,000 by December 31, 1998. As a result of amendments signed in 
December 1997 and September 1998, 62 Diamond Field Emission patents were 
assigned directly to the Company and 82 patents were returned to MCC. The 
Company agreed to pay a royalty fee of 2% of future commercial revenues 
related to the patents assigned to it. The Company has the right to offset 
one half of the costs of maintaining these patents against any royalties due 
under the agreement. MCC agreed to accept a cash payment of $5,000 and 
500,000 shares of the Company's common stock in exchange for releasing the 
Company from the minimum royalty agreement. As of December 31, 1997 the 
Company had accrued $355,000 due under the minimum royalty agreement 
representing the minimum royalty payment of $500,000 less $145,000 of costs 
incurred in maintaining the patents. The stock issued in connection with this 
agreement was valued at $100,000 based on the market price at the time. The 
remaining $250,000 was taken into income 1998.

DiaGasCrown Venture

     In February 1995, the Company entered into an agreement with 
Diagascrown, Inc., a Russian joint stock company controlled by 
Gazcomplektimpex, a subsidiary of Gazprom, the Russian national natural gas 
company. In return for an equity position in the Company, DGC paid the 
Company $5,000,000 and granted the Company an exclusive license to DGC 
display and related diamond technology and license rights to all related 
background patents. The Company has committed to perform $2.5 million in 
research and development in Russia. According to its internal records, the 
Company has spent approximately $2.0 million on this research through 
December 31, 1998. Spending in Russia has been halted since 1996 pending 
agreement as to the nature and amount of the services to be performed in 
Russia for the remaining balance to be spent under the original agreement. 
There have been no substantive discussions related to future spending in 
Russia since the time that spending was halted.

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.

Legal Proceedings

     On May 20, 1996, Semi-Alloys Company, a former customer of Plasmatron, 
filed a complaint with the Supreme Court of the State of New York, County of 
Westchester. The complaint names Plasmatron, the Company and Westchester Fire 
Insurance Company as defendants. Semi-Alloys claims a breach of contract 
related to $1 million of coating equipment that Plasmatron delivered in 1993, 
prior to the Company's ownership of Plasmatron. Semi-Alloys claims the 
equipment does not perform as required under the contract. Semi-Alloys seeks 
to recover compensatory, consequential and incidental damages. The amount of 
this claim is to be determined at trial. A trial date has been set for August 
1999. At this time the outcome can not be predicted with any certainty and 
the potential liability, if any, is unknown. The Company believes it has 
meritorious defenses and intends to continue to vigorously defend this action.

11.  COMMITMENTS AND CONTINGENCIES (CONTINUED):

Legal Proceedings (continued)

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

     On August 18, 1998, KDF Electronic & Vacuum Services, Inc., a vendor of 
DTO, filed a complaint in the United Sates District Court for the Southern 
District of New York against the Company for unpaid debts of its subsidiary, 
Diamond Tech One, Inc. The Company was served with notice of this suit on 
October 14, 1998. All known amounts owed by DTO to the KDF are recorded as 
liabilities of DTO in the consolidated financial statements of the Company. 
The amounts recorded as liabilities by DTO make up substantially all of the 
amounts claimed as due by KDF. No trial date has been set in this matter. 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 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. 
The Company contends that Aetna failed in its duty to mitigate damages and 
behaved in a reckless manner, which resulted in damages to the Company and 
its property. The Company intends to file a counterclaim against Aetna and 
its property manager for damages and the return of its security deposit. The 
Company believes that the ultimate resolution of this matter will not have a 
material impact on the consolidated financial statements of the Company.

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

Impact of the Year 2000 Issue

     The Company has determined that the Year 2000 Issue will have an 
immaterial effect on the Company. The Year 2000 Issue is the result of 
computer programs being written using two digits rather than four to define 
the applicable year. Any of the Company's computer programs that have 
date-sensitive software may recognize a date using "00" as the year 1900 
rather than the year 2000. This could result in a system failure or 
miscalculations causing disruptions of operations, including, among other 
things, a temporary inability to process transactions, send invoices, or 
engage in similar normal business activities.

     Based on a recent assessment, the Company determined that it will be 
required to modify or replace portions of its software so that its computer 
systems will properly utilize dates beyond December 31, 1999. All of this 
software is prepackaged software that was purchased from outside vendors. 
These vendors all have upgrades available which correct the Year 2000 Issue. 
It is the Company's plan to purchase the upgraded software, where required, 
in early 1999 to insure adequate time for implementation. The cost of these 
upgrades is expected to be no greater than $20,000 and it is not expected to 
have a material effect on the operations of the Company. If such upgrades are 
not installed on a timely basis, the Year 2000 Issue could have a material 
impact on the operations of the Company.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

11.  COMMITMENTS AND CONTINGENCIES (CONTINUED):


Impact of the Year 2000 Issue (continued)

     The Company has determined that it is not vulnerable to a third party's 
failure to remediate its own Year 2000 Issues since it has no significant 
suppliers or large customers. The Company has also determined that it has no 
exposure to contingencies related to the Year 2000 Issue for the products it 
has sold. The Company is ensuring that all products currently under 
development by the Company will be Year 2000 compliant prior to the sale of 
such products.

     This assessment is based on the present circumstances of the Company in 
which the Company has virtually no customers and no significant suppliers. In 
this scenario, the Company's Year 2000 risk is virtually non-existent. If the 
Company's business plan is successful and it is able to develop and sell 
products, the Company may become subject to Year 2000 risk related to third 
parties. The Company intends to assess the risk associated with third party 
remediation of Year 2000 issues at the time that it enters into any 
significant contracts or relationships with third parties and to develop a 
contingency plan at that time if necessary.

12.  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, 1998 and 1997, 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 has not incurred any material losses on these 
receivables.

13.  SEGMENT INFORMATION:

     The Company had no revenues from government contracts in 1998 and had 
approximately $854,000 in revenues from government contracts in 1997. The 
majority of the government contracts are cost reimbursement contracts. As a 
result, the Company realizes little or no gain or loss in the performance of 
these contracts. The Company's contracts involving the United States 
government are or may be subject to various risks, including unilateral 
termination for the convenience of the government. As of December 31, 1998, 
the Company had no material commitment for future government funding.

14.  RELATED PARTY TRANSACTIONS:

     As described in Note 5, the Company has notes payable to its Chief 
Executive Officer. The $185,000 balance due at December 31, 1997 and secured 
by all assets of DTO was repaid at the time of the DTO sale in May 1998. 
Additional advances totaling $100,000 were made to the Company at subsequent 
dates. These advances are convertible into shares of the Company's common 
stock at a rate of $0.25 per share.

14.      RELATED PARTY TRANSACTIONS (CONTINUED):

     In October 1998, Electronic Billboard Technology, Inc., a subsidiary of 
the Company entered into a Patent Assignment and Royalty Agreement with 
Advanced Technology Incubator, Inc., ("ATI") a corporation based in Austin, 
Texas and owned by Dr. Zvi Yaniv, the Company's President and Chief Operating 
Officer. Under the terms of the agreement, ATI agreed to assign U.S. Patent 
No. 5,469,187 related to certain LCD technology to EBT in exchange for an 
initial payment of $200,000. In addition, ATI is entitled to receive a 
royalty of 5% of gross revenue related to products using this patent. EBT 
intends to use this technology in the development of its next generation 
electronic billboard product. EBT may terminate this assignment at any time 
upon 30 days written notice to ATI. The assignment may be terminated by ATI 
if, within two years of the first sale or lease of a billboard using this 
technology, cumulative royalty payments under the agreement have not totaled 
$500,000, or if payments do not equal $500,000 in any one year period 
following this initial two year period. If the assignment is terminated by 
ATI, EBT will be granted a non-exclusive worldwide license to use the 
technology under terms similar to those contained in this agreement. ATI had 
the right to terminate this agreement if the initial payment was not received 
by February 15, 1999. The payment was not made by that date, however, the 
parties have agreed to extend the initial payment deadline to April 15, 1999.

15.  SUBSEQUENT EVENTS:

     In January and February 1999, the Company 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 the common stock of the Company at rates ranging from $0.30 
to $0.40 per share, which approximated the market price of the Company's 
common stock at the times the loans were arranged. These notes, including 
interest, were converted into 590,697 shares of the 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.

     In February 1999, holders of the notes payable described in greater 
detail in Note 5 converted notes with a face amount totaling $705,000 and the 
related accrued interest into 3,006,674 shares of the Company's common stock 
pursuant to the terms of the notes.

     In January 1999, the Company received $225,000 in contract research 
revenues to fund phase II development of its DFE cathode. The funds were 
received from DPN, the holder of FEPET's preferred stock (See Note 7). The 
funds will be recognized as revenue over the term of the of the development 
project, which is expected to be completed in 1999.

     The Series A preferred shares were converted into 125,275 shares of SI 
Diamond common stock in March 1999.

     In March 1999, the Company signed a license agreement with a large 
manufacturer of information and office products. Under the terms of this 
agreement, the Company will receive gross royalties of $5,555,556 no later 
than April 12, 1999 for a paid up worldwide non-exclusive license to certain 
of the Company's patents and patent applications. After foreign taxes 
associated with this payment, the Company will net $5,000,000.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

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

         Based solely on review of the copies of such reports furnished to 
the Company, or written representations that no reports were required, the 
Company believes that for the period from January 1, 1998 through December 
31, 1998, all its officers, Directors, and greater than 10% beneficial owners 
complied with all Section 16(a) filing requirements applicable to them, with

         The following table sets forth certain information concerning the 
number and intrinsic value of the options held by the named executives at 
December 31, 1998. There were no options exercised by Named Executive 
Officers during the fiscal year ended December 31, 1998 and accordingly no

price of $0.40 per share of the common stock on December 31, 1998, on the 
NASDAQ OTC Bulletin Board System. They do not reflect the actual amounts, if 
any, which may be realized upon the future exercise of remaining stock 
options and should not be considered indicative of future stock performance.

- -----------------
(1) Directors who are also executives of the Company 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.

(2) All Directors receive $150 per board meeting or committee meeting 
attended in person, and $50 per telephonic meeting. No cash payments were 
made to Directors in 1998. The amounts due, as reflected in this table, were 
voluntarily deferred by the Directors to aid the Company's cash flow. 
Reasonable expenses incurred by each Director in connection with his duties 
as a Director are also reimbursed by the Company. This amount is not 
reflected in the above table.

(3) All outside Directors of the Company participate in the Company's Amended 
and Restated 1992 Outside Directors Stock Option Plan, under which the 
Company may grant stock options to any Director who is not a full time 
salaried employee of the Company. Each Director was granted 20,000 options 
under this plan on July 27, 1998 at a price of $0.25 per share. These option 
grants became exercisable in full on that date. The Board of Directors also 
established the 1998 Directors and Officers Stock Option Plan in 1998. Each 
outside Director was granted 150,000 fully vested options under this plan on 
May 11, 1998. These options are exercisable at a price of $0.375 per share.

                                    Page 50
<PAGE>

           In May 1998, the Company's Board of Directors passed a resolution 
that changed the option exercise price of certain options previously granted 
under the Amended and Restated 1992 Outside Directors Stock Option Plan. A 
total of 284,903 options were repriced. The Company reduced the exercise 
price to $0.375 for all options for all persons who were Directors of the 
Company at the time of the repricing. The original exercise price of these 
options ranged from $1.125 to $5.50. The market price of the Company's common 
stock at the time the exercise price of these options was reduced was 
approximately $0.25 per share.

           All of the Company's Directors have retained the right to pursue 
additional business activities that are not competitive with the business of 
the Company, 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 
the Company or the shareholders by virtue of their participation in such 
additional business activities.
                                       
                             EMPLOYMENT AGREEMENTS

         The Company has an employment agreement with Dr. Zvi Yaniv, its 
President and Chief Operating Officer, which was entered into on June 1, 
1996. Under the terms of this agreement Dr. Yaniv was to be paid a base 
salary of $125,000 per year. The contract was amended to adjust Dr. Yaniv's 
salary to $150,000 per year effective November 1, 1998. All contingent 
compensation related to bonuses or performance goals were eliminated.

         The Company also provides Dr. Yaniv with the use of an automobile 
owned by the Company and paid for his reasonable living expenses in Austin, 
Texas until June 1, 1997. In May 1998, the Company paid moving expenses for 
the transportation of Dr. Yaniv's household goods in connection with the 
relocation of Dr. Yaniv's primary residence to Austin, Texas. The employment 
agreement may be terminated by either party, with or without cause, by giving 
30 days notice of termination to the other party.

(1)  The original ten-year terms and the vesting schedules of each grant
     repriced were not changed with the repricing of the options listed in this
     table.

(2)  Prior to repricing, the options in this grant were to be priced at the
     market price on the vesting date of the options granted. The 100,000 
     options of this grant that had vested at June 1, 1996 were priced at $5.00 
     per share of common stock. No other options pursuant to this grant had 
     vested as of the repricing date.

         The options for the above referenced Named Executive Officers that 
were repriced in 1998 were part of a plan approved by the Board of Directors 
on May 11, 1998. On that date all options held by the above referenced Named 
Executive Officers were repriced to reduce the exercise price to $0.375 per 
share. As of that date the Company's common stock was trading at $0.25 per 
share. The Board of Directors, on March 27, 1998, had previously reduced the 
exercise price to $0.375 for all other employees of the Company as of that 
date. The market price of the Company's common stock was $0.135 per share on 
March 27, 1998. The options were repriced to provide greater motivation to 
the employees that had remained with the Company. The Board of Directors 
believed that the substantial decline in the price of the Company's common 
stock was the result of many factors that were not related to the performance 
of the remaining employees.

         The options that were repriced in 1997 for the above referenced 
Named Executive Officers were repriced as part of a plan approved by the 
Board of Directors on July 28, 1997. On that date, 25% of all options held by 
employees employed by the Company on that date that had an exercise price in 
excess of $2.00 per share were changed to reduce the exercise price to $2.00. 
As of that date the Company's common stock was trading at $1.125 per share. 
The options were repriced to provide greater motivation to the employees that 
had remained with the Company. The Board of Directors believed that the 
substantial decline in the price of the Company's common stock was the result 
of many factors that were not related to the performance of the remaining

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         In October 1998, Electronic Billboard Technology, Inc., a subsidiary 
of the Company entered into a Patent Assignment and Royalty Agreement with 
Advanced Technology Incubator, Inc., ("ATI") a corporation based in Austin, 
Texas and owned by Dr. Zvi Yaniv, the Company's President and Chief Operating 
Officer. Under the terms of the agreement, ATI agreed to assign U.S. Patent 
No. 5,469,187 related to certain LCD technology to EBT in exchange for an 
initial payment of $200,000. In addition, ATI is entitled to receive a 
royalty of 5% of gross revenue related to products using this patent. EBT 
intends to use this technology in the development of its next generation 
electronic billboard product. EBT may terminate this assignment at any time 
upon 30 days written notice to ATI. The assignment may be terminated by ATI 
if, within two years of the first sale or lease of a billboard using this 
technology, cumulative royalty payments under the agreement have not totaled 
$500,000, or if payments do not equal $500,000 in any one year period 
following this initial two year period. If the assignment is terminated by 
ATI, EBT will be granted a non-exclusive worldwide license to use the 
technology under terms similar to those contained in this agreement. ATI had 
the right to terminate this agreement if the initial payment was not received 
by February 15, 1999. The payment was not made by that date, however; the 
parties have agreed to extend the initial payment deadline to April 15, 1999.

         At various times, the Company has borrowed money from its Chief 
Executive Officer. Mr. Eller made a $185,000 loan to the Company in 1997 that 
was repaid at the time of the DTO sale in May 1998. Additional advances 
totaling $100,000 were made to the Company at subsequent dates. These 
advances are convertible into shares of the Company's common stock at a rate 
of $0.25 per share.

                          OF SI DIAMOND TECHNOLOGY, INC.
             ESTABLISHING AND DESIGNATING SERIES OF PREFERRED STOCK
        AS "SERIES H JUNIOR PARTICIPATING PREFERRED STOCK" AND FIXING AND
            DETERMINING THE RELATIVE RIGHTS AND PREFERENCES THEREOF


TO THE SECRETARY OF STATE OF THE STATE OF TEXAS:

     SI Diamond Technology, Inc., a Texas corporation (the "Corporation") 
pursuant to the provisions of Article 2.13 of the Texas Business Corporation 
Act, submits the following statement for the purpose of establishing and 
designating a series of shares and fixing and determining the preferences, 
limitations and relative rights thereof:

     1.     The name of the corporation is SI DIAMOND TECHNOLOGY, INC.

     2.     The Amended and Restated Articles of Incorporation of the 
Corporation authorizes the issuance of up to 2,000,000 shares of Preferred 
Stock, $1.00 par value per share, and expressly vests in the Board of 
Directors of the Corporation the authority provided therein to issue any or 
all of said shares in one or more series and by resolution or resolutions to 
establish the designation, number, full or limited voting powers, or the 
denial of voting powers, preferences and relative, participating, optional, 
and other special rights and the qualifications, limitations, restrictions, 
and other distinguishing characteristics of each series to be issued.

     3.     The Board of Directors of the Corporation, pursuant to the 
authority expressly vested in it as aforesaid, has adopted the following 
resolutions creating a Series H Junior Participating Preferred Stock:

     RESOLVED, that Six Hundred Thousand (600,000) of the 2,000,000 
authorized shares of Preferred Stock of the Corporation shall be designated 
Series H Junior Participating Preferred Stock (the "Series H Preferred 
Stock") and shall possess the rights and privileges set forth below:

     SERIES H JUNIOR PARTICIPATING PREFERRED SHARES.

     1.     DESIGNATION AND AMOUNT.  There shall be a series of shares of 
preferred stock that shall be designated as "Series H Junior Participating 
Preferred Shares," and the number of shares constituting such series shall be 
Six Hundred Thousand (600,000).  

     2.     DIVIDENDS AND DISTRIBUTIONS.

     (A)    Subject to the prior and superior rights of the holders of any 
shares of any series of shares of preferred stock ranking prior and superior 
to the Series H Junior Participating Preferred Shares with respect to 
dividends, the holders of shares of Series H Junior Participating Preferred 
Shares, in preference to the holders of shares of any class or series of 
shares of the Corpora-

<PAGE>

tion ranking prior to the Series H Junior Participating Preferred Shares, 
shall be entitled to receive, when, as and if declared by the Board of 
Directors out of funds legally available for the purpose, quarterly dividends 
payable in cash on the 15th day of January, April, July and October in each 
year (each such date being referred to herein as a "Quarterly Dividend 
Payment Date"), commencing on the first Quarterly Dividend Payment Date after 
the first issuance of a share or fraction of a share of Series H Junior 
Participating Preferred Shares, in an amount per share (rounded to the 
nearest cent) equal to the greater of (a) $1.00 or (b) subject to the 
provision for adjustment hereinafter set forth, the Adjustment Number (as 
defined below) times the aggregate per share amount of all cash dividends, 
and the Adjustment Number times the aggregate per share amount (payable in 
kind) of all non-cash dividends or other distributions other than a dividend 
payable in shares of common stock or a subdivision of the outstanding shares 
of common stock (by reclassification or otherwise), declared on the shares of 
common stock of the Corporation (the "Common Shares") since the immediately 
preceding Quarterly Dividend Payment Date, or, with respect to the first 
Quarterly Dividend Payment Date, since the first issuance of any share or 
fraction of a share of Series H Junior Participating Preferred Shares.  The 
"Adjustment Number" shall initially be 100. In the event the Corporation 
shall at any time after June 18, 1998 (the "Rights Declaration Date") (i) 
declare any dividend on Common Shares payable in Common Shares, (ii) 
subdivide the outstanding Common Shares or (iii) combine the outstanding 
Common Shares into a smaller number of shares, then in each such case the 
Adjustment Number in effect immediately prior to such event shall be adjusted 
by multiplying such Adjustment Number by a fraction the numerator of which is 
the number of Common Shares outstanding immediately after such event and the 
denominator of which is the number of Common Shares that were outstanding 
immediately prior to such event.

     (B)    The Corporation shall declare a dividend or distribution on the 
Series H Junior Participating Preferred Shares as provided in paragraph (A) 
above immediately after it declares a dividend or distribution on the Common 
Shares (other than a dividend payable in Common Shares); provided that, in 
the event no dividend or distribution shall have been declared on the Common 
Shares during the period between any Quarterly Dividend Payment Date and the 
next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per 
share on the Series H Junior Participating Preferred Shares shall 
nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

     (C)    Dividends shall begin to accrue and be cumulative on outstanding 
Series H Junior Participating Preferred Shares from the Quarterly Dividend 
Payment Date next preceding the date of issue of such Series H Junior 
Participating Preferred Shares, unless the date of issue of such shares is 
prior to the record date for the first Quarterly Dividend Payment Date, in 
which case dividends on such shares shall begin to accrue from the date of 
issue of such shares, or unless the date of issue is a Quarterly Dividend 
Payment Date or is a date after the record date for the determination of 
holders of Series H Junior Participating Preferred Shares entitled to receive 
a quarterly dividend and before such Quarterly Dividend Payment Date, in 
either of which events such dividends shall begin to accrue and be cumulative 
from such Quarterly Dividend Payment Date.  Accrued but unpaid dividends 
shall not bear interest.  Dividends paid on the Series H Junior Par-
                                       



                                      -2-

ticipating Preferred Shares in an amount less than the total amount of such 
dividends at the time accrued and payable on such shares shall be allocated 
pro rata on a share by share basis among all such shares at the time 
outstanding.  The Board of Directors may fix a record date for the 
determination of holders of Series H Junior Participating Preferred Shares 
entitled to receive payment of a dividend or distribution declared thereon, 
which record date shall be no more than 30 days prior to the date fixed for 
the payment thereof.

     3.     VOTING RIGHTS.  The holders of Series H Junior Participating 
Preferred Shares shall have the following voting rights:

     (A)    Each Series H Junior Participating Preferred Share shall entitle 
the holder thereof to a number of votes equal to the Adjustment Number on all 
matters submitted to a vote of the shareholders of the Corporation.

     (B)    Except as otherwise provided herein or by law, the holders of 
Series H Junior Participating Preferred Shares and the holders of the Common 
Shares shall vote together as one class on all matters submitted to a vote of 
shareholders of the Corporation.

     (C)    (i)     If at any time dividends on any Series H Junior 
Participating Preferred Stock shall be in arrears in an amount equal to six 
(6) quarterly dividends thereon, the occurrence of such contingency shall 
mark the beginning of a period (herein called a "default period") which shall 
extend until such time when all accrued and unpaid dividends for all previous 
quarterly dividend periods and for the current quarterly dividend period on 
all shares of Series H Junior Participating Preferred Stock then outstanding 
shall have been declared and paid or set apart for payment.  During each 
default period, all holders of Preferred Stock (including holders of the 
Series H Junior Participating Preferred Stock) with dividends in arrears in 
an amount equal to six (6) quarterly dividends thereon, voting as a class, 
irrespective of series, shall have the right to elect two (2) Directors.

     (ii)   During any default period, such voting right of the holders of 
Series H Junior Participating Preferred Stock may be exercised initially at a 
special meeting called pursuant to subparagraph (iii) of this Section 3(C) or 
at any annual meeting of stockholders, and thereafter at annual meetings of 
stockholders, provided that such voting right shall not be exercised unless 
the holders of ten percent (10%) in number of shares of Preferred Stock 
outstanding shall be present in person or by proxy.  The absence of a quorum 
of the holders of Common Stock shall not affect the exercise by the holders 
of Preferred Stock of such voting right.  At any meeting at which the holders 
of Preferred Stock shall exercise such voting right initially during an 
existing default period, they shall have the right, voting as a class, to 
elect Directors to fill such vacancies, if any, in the Board of Directors as 
may then exist up to two (2) Directors or, if such right is exercised at an 
annual meeting, to elect two (2) Directors.  If the number which may be so 
elected at any special meeting does not amount to the required number, the 
holders of Preferred Stock shall have the right to make such increase in the 
number of Directors as shall be necessary to permit the election by them of 
the required number.  After the holders of the Preferred Stock shall have 
                                       



                                      -3-

<PAGE>

exercised their right to elect Directors in any default period and during the 
continuance of such period, the number of Directors in any default period and 
during the continuance of such period, the number of Directors shall not be 
increased or decreased except by vote of the holders of the Preferred Stock 
as herein provided or pursuant to the rights of any equity securities ranking 
senior to or pari passu with the Series H Junior Participating Preferred 
Stock.

     (iii)  Unless the holders of Preferred Stock shall, during an existing 
default period, have previously exercised their right to elect Directors, the 
Board of Directors may order, or any stockholder or stockholders owning in 
the aggregate not less than ten percent (10%) of the total number of shares 
of Preferred Stock outstanding, irrespective of series, may request, the 
calling of special meeting of the holders of Preferred Stock, which meeting 
shall thereupon be called by the President, a Vice President or the Secretary 
of the Corporation.  Notice of such meeting and of any annual meeting at 
which holders of Preferred Stock are entitled to vote pursuant to this 
Paragraph (C)(iii) shall be given to each holder of record of Preferred Stock 
by mailing a copy of such notice to him or her at his or her last address as 
the same appears on the books of the Corporation.  Such meeting shall be 
called for a time not earlier than 10 days and not later than 50 days after 
such order or request or in default of the calling of such meeting within 50 
days after such order or request, such meeting may be called on similar 
notice by any stockholder or stockholders owning in the aggregate not less 
than ten percent (10%) of the total number of shares of Preferred Stock 
outstanding.  Notwithstanding the provisions of this Paragraph (C)(iii), no 
such special meeting shall be called during the period within 50 days 
immediately preceding the date fixed for the next annual meeting of the 
stockholders.

     (iv)   In any default period, the holders of Common Stock, and other 
classes of stock of the Corporation if applicable, shall continue to be 
entitled to elect the whole number of Directors until the holders of 
Preferred Stock shall have exercised their right to elect two (2) Directors 
voting as a class, after the exercise of which right (x) the Directors so 
elected by the holders of Preferred Stock shall continue in office until 
their successors shall have been elected by such holders or until the 
expiration of the default period, and (y) any vacancy in the Board of 
Directors may (except as provided in Paragraph (C)(ii) of this Section 3) be 
filled by vote of a majority of the remaining Directors theretofore elected 
by the holders of the class of stock which elected the Director whose office 
shall have become vacant.  References in this Paragraph (C) to Directors 
elected by the holders of a particular class of stock shall include Directors 
elected by such Directors to fill vacancies as provided in clause (y) of the 
foregoing sentence.

     (v)    Immediately upon the expiration of a default period, (x) the 
right of the holders of Preferred Stock as a class to elect Directors shall 
cease, (y) the term of any Directors elected by the holders of Preferred 
Stock as a class shall terminate, and (z) the number of Directors shall be 
such number as may be provided for in the certificate of incorporation or 
bylaws irrespective of any increase made pursuant to the provisions of 
Paragraph (C)(ii) of this Section 3 (such number being subject, however, to 
change thereafter in any manner provided by law or in the certificate of 
incorporation or bylaws).  Any vacancies in the Board of Directors effected 
by the provisions 
                                       



                                      -4-

<PAGE>

of clauses (y) and (z) in the preceding sentence may be filled by a majority 
of the remaining Directors.

     (D)    Except as set forth herein or as provided by law, holders of 
Series H Junior Participating Preferred Shares shall have no special voting 
rights and their consent shall not be required (except to the extent they are 
entitled to vote with holders of the Common Shares as set forth herein) for 
taking any corporate action.

     4.     CERTAIN RESTRICTIONS.

     (A)    Whenever quarterly dividends or other dividends or distributions 
payable on the Series H Junior Participating Preferred Shares as provided in 
Section 2 are in arrears, thereafter and until all accrued and unpaid 
dividends and distributions, whether or not declared, on Series H Junior 
Participating Preferred Shares outstanding shall have been paid in full, the 
Corporation shall not

            (i)     declare or pay dividends on, make any other distributions
     on, or redeem or purchase or otherwise acquire for consideration any 
     shares ranking junior (either as to dividends or upon liquidation, 
     dissolution or winding up) to the Series H Junior Participating Preferred 
     Shares;

            (ii)    declare or pay dividends on or make any other distributions
     on any shares ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Series H Junior
     Participating Preferred Shares, except dividends paid ratably on the Series
     H Junior Participating Preferred Shares and all such parity shares on which
     dividends are payable or in arrears in proportion to the total amounts to
     which the holders of all such shares are then entitled;

            (iii)   redeem or purchase or otherwise acquire for consideration
     any shares ranking on a parity (either as to dividends or upon liquidation,
     dissolution or winding up) with the Series H Junior Participating Preferred
     Shares, provided that the Corporation may at any time redeem, purchase or
     otherwise acquire any such parity shares in exchange for any shares of the
     Corporation ranking junior (both as to dividends and upon dissolution,
     liquidation or winding up) to the Series H Junior Participating Preferred
     Shares; or

            (iv)    purchase or otherwise acquire for consideration any shares
     of Series H Junior Participating Preferred Shares, or any shares ranking on
     a parity with the Series H Junior Participating Preferred Shares, except in
     accordance with a purchase offer made in writing or by publication (as
     determined by the Board of Directors) to all holders of such shares upon
     such terms as the Board of Directors, after consideration of the respective
     annual dividend rates and other relative rights and preferences of the
     respective series and classes, shall determine in good faith will result in
     fair and equitable treatment among the respective series or classes.
                                       



                                      -5-

<PAGE>

     (B)    The Corporation shall not permit any subsidiary of the 
Corporation to purchase or otherwise acquire for consideration any shares of 
the Corporation unless the Corporation could, under paragraph (A) of this 
Section 4, purchase or otherwise acquire such shares at such time and in such 
manner.

     5.     REACQUIRED SHARES.  Any Series H Junior Participating Preferred 
Shares purchased or otherwise acquired by the Corporation in any manner 
whatsoever shall be retired and canceled promptly after the acquisition 
thereof. All such shares shall upon their cancellation become authorized but 
unissued shares of preferred stock and may be reissued as part of a new 
series of shares of preferred stock.

     6.     LIQUIDATION, DISSOLUTION OR WINDING UP.

     (A)    Upon any liquidation (voluntary or otherwise), dissolution or 
winding up of the Corporation, no distribution shall be made to the holders 
of shares ranking junior (either as to dividends or upon liquidation or 
winding up) to the Series H Junior Participating Preferred Shares, unless, 
prior thereto, the holders of Series H Junior Participating Preferred Shares 
shall have received $1.00 per share, plus an amount equal to accrued and 
unpaid dividends and distributions thereon, whether or not declared, to the 
date of such payment (the "Series H Liquidation Preference").  Following the 
payment of the full amount of the Series H Liquidation Preference, no 
additional distributions shall be made to the holders of Series H Junior 
Participating Shares unless, prior thereto, the holders of Common Shares 
shall have received an amount per share (the "Common Adjustment") equal to 
the quotient obtained by dividing (i) the Series H Liquidation Preference by 
(ii) the Adjustment Number.  Following the payment of the full amount of the 
Series H Liquidation Preference and the Common Adjustment in respect of all 
outstanding shares of Series H Junior Participating Preferred Shares and the 
Common Shares, respectively, holders of Series H Junior Participating 
Preferred Shares and holders of the Common Shares shall receive their ratable 
and proportionate share of the remaining assets to be distributed in the 
ratio of the Adjustment Number to 1 with respect to such Preferred Shares and 
the Common Shares, on a per share basis, respectively.

     (B)    In the event, however, that there are not sufficient assets to 
permit payment in full of the Series H Liquidation Preference and the 
liquidation preferences of all other series of shares of preferred stock, if 
any, that rank on a parity with the Series H Junior Participating Preferred 
Shares, then such remaining assets shall be distributed ratably to the 
holders of such parity shares in proportion to their respective liquidation 
preferences. In the event, however, that there are not sufficient assets 
available to permit payment in full of the Common Adjustment, then such 
remaining assets shall be distributed ratably to the holders of the Common 
Shares.

     7.     CONSOLIDATION, MERGER, ETC.  In case the Corporation shall enter 
into any consolidation, merger, or other transaction in which the Common 
Shares are exchanged for or changed into other shares or securities, cash 
and/or other property, then in any such case, the Series H Junior 
Participating Preferred Shares shall at the same time be similarly exchanged 
or changed in an 
                                       



                                      -6-

<PAGE>

amount per share equal to the Adjustment Number times the aggregate amount of 
shares, securities, cash and/or any other property (payable in kind), as the 
case may be, into which or for which each Common Share is changed or 
exchanged.

     8.     NO REDEMPTION.  The Series H Junior Participating Shares shall 
not be redeemable.  Notwithstanding the foregoing sentence of this Section, 
the Corporation may acquire Series H Junior Participating Preferred Shares in 
any other manner permitted by law.

     9.     RANKING.  The Series H Junior Participating Preferred Shares 
shall rank junior to all other series of the Corporation's preferred stock as 
to the payment of dividends and the distribution of assets, unless the terms 
of any such series shall provide otherwise.

    10.     AMENDMENT.  At any time that any Series H Junior Participating 
Preferred Shares are outstanding, these Articles of Incorporation shall not 
be amended in any manner which would materially alter or change the powers, 
preferences or special rights of the Series H Junior Participating Preferred 
Shares so as to affect them adversely without the affirmative vote of the 
holders of a majority or more of the outstanding Series H Junior 
Participating Preferred Shares, voting separately as a class.

     11.    FRACTIONAL SHARES.  Series H Junior Participating Preferred 
Shares may be issued in fractions of a share that shall entitle the holder, 
in proportion to such holder's fractional shares, to exercise voting rights, 
receive dividends, participate in distributions and to have the benefit of 
all other rights of holders of Series H Junior Participating Preferred Shares.

     FURTHER RESOLVED, that the statements contained in the foregoing 
resolutions creating and designating the said Series H Preferred Stock and 
fixing the number, powers, preferences and relative, optional, participating, 
and other special rights and the qualifications, limitations, restrictions, 
and other distinguishing characteristics thereof shall, upon the effective 
date of said series, be deemed to be included in and be a part of the Amended 
and Restated Articles of Incorporation of the Corporation pursuant to the 
provisions of the Texas Business Corporation Act.

     Signed on June 24, 1998.

     THE SECURITIES REPRESENTED BY THIS WARRANT MAY NOT BE OFFERED FOR
     SALE, SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT MADE UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED (THE "ACT"), OR PURSUANT TO AN EXEMPTION FROM REGISTRATION
     UNDER THE ACT, THE AVAILABILITY OF WHICH IS TO BE ESTABLISHED TO THE
     SATISFACTION OF THE COMPANY.
                                       
                                    WARRANT

                          SI DIAMOND TECHNOLOGY, INC.

               The Transferability of this Warrant is Restricted
                            as Provided in Article 3

     FOR GOOD AND VALUABLE consideration, the receipt of which is hereby 
acknowledged by SI DIAMOND TECHNOLOGY, INC., 3006 Longhorn Boulevard, Austin, 
Texas  78758,  a Texas corporation (the "Company"),  Dale Kerner  ("Holder"), 
is hereby granted the right to purchase, at the initial exercise price of 
$0.25 per share, 100,000 shares of the Company's common stock, $.001 par 
value (the "Common Shares").

     Subject to the further terms hereof, this Warrant shall be exercisable 
in whole or in part at any time and from time to time prior to 11:59 p.m. 
(Austin time) on October 29, 1999.  This Warrant shall be exercisable only in 
the event that the exercise is for, at a minimum, the lesser of (i) 10,000 
Common Shares or (ii) the remaining number of Common Shares which the 
registered holder of this Warrant has the right to purchase thereunder.  Upon 
the expiration of the applicable period for exercise of this Warrant, this 
Warrant shall no longer entitle the holder thereof to acquire any shares of 
Common Shares or any other security of the Company.  For the purposes of this 
Warrant, "Affiliates" or "Affiliate" of Holder shall mean any person or 
entity that directly, or indirectly through one or more intermediaries, 
controls, or is controlled by, or is under common control with Holder.  
"Control" in, of or by an Affiliate requires ownership of more than fifty 
percent (50%) of (i) voting stock of a company which issued voting stock, or 
(ii) ownership interest in any enterprise; an entity or person is an 
Affiliate only as long as control exists.

     This Warrant initially is exercisable in whole or part as provided above 
at a price of $0.25 per Share payable by wire transfer of collected funds, 
subject to adjustment as provided in Article 5 hereof.  Upon surrender of 
this Warrant, with the annexed Subscription Form duly executed, together with 
payment of the Purchase Price (as hereinafter defined) for the Common Shares 
purchased, at the offices of the Company, the registered holder of this 
Warrant shall be entitled to receive a certificate or certificates for all 
the Common Shares.

<PAGE>

1.   EXERCISE OF WARRANT

     The purchase rights represented by this Warrant are exercisable at the
     option of the Holder hereof, in whole Common Shares only (but not as to
     fractional Common Shares underlying this Warrant), during any period in
     which this Warrant may be exercised as set forth above.

     If this Warrant is exercised in part only, the Company, upon surrender of
     this Warrant for cancellation, shall execute and deliver a new Warrant of
     like tenor evidencing the right of the holder to purchase the balance of
     the Common Shares purchasable hereunder.

2.   ISSUANCE OF CERTIFICATES

     Upon the exercise of this Warrant, the issuance of certificates for Common
     Shares underlying this Warrant shall be made forthwith (and in any event
     within five business days thereafter) without charge to the Holder hereof
     including, without limitation, any tax which may be payable in respect of
     the issuance thereof, and such certificates shall (subject to the
     provisions of Article 3 hereof) be issued in the name of, or in such names
     as may be directed by, the Holder hereof; provided, however, that the
     Company shall not be required to pay any tax which may be payable in
     respect of any transfer involved in the issuance and delivery of any such
     certificates in a name other than that of the Holder and the Company shall
     not be required to issue or deliver such certificates unless or until the
     person or persons requesting the issuance thereof shall have paid to the
     Company the amount of such tax or shall have established to the
     satisfaction of the Company that such tax has been paid.  The certificates
     representing the Common Shares underlying this Warrant shall be executed on
     behalf of the Company by the manual or facsimile signature of one of the
     present or any future Chairman or President of the Company and any present
     or future Vice President or Secretary of the Company.  Upon transfer of
     this Warrant in whole or in part to an Affiliate of Holder, such transferee
     shall be entitled to all the rights of a Holder hereof.

3.   RESTRICTION ON TRANSFER OF WARRANT AND COMMON SHARES

     The Holder of this Warrant, by its acceptance hereof, covenants and agrees
     that this Warrant and the Common Shares are being acquired as an investment
     and not with a view to the distribution thereof, and that the Warrant may
     not be exercised, and neither the Warrant nor the Shares may be sold,
     transferred, assigned, hypothecated or otherwise disposed of (other than to
     an Affiliate of Holder), in whole or in part unless in the opinion of
     counsel reasonably concurred in by the Company's counsel such transfer is
     in compliance with all applicable securities laws, after which this Warrant
     and the Common Shares shall again be subject to the restrictions contained
     in this Article 3.

          the initial purchase price in accordance with the provisions of
          Article 5 hereof.

     5.1. SUBDIVISION AND COMBINATION

          In case the Company shall at any time subdivide or combine the

          proportionately decreased in the case of subdivision or increased 
          in the case of combination.

     5.2. RECLASSIFICATION, CONSOLIDATION, MERGER, ETC.

          In case of any reclassification or change of the outstanding Common
          Shares (other than a change in par value to no par value, or from no
          par value to par value, or as a result of a subdivision or
          combination), or in the case of any consolidation of the Company with,
          or merger of the Company into, another corporation (other than a
          consolidation or merger in which the Company is the surviving
          corporation and which does not result in any reclassification or
          change of the outstanding Common Shares, except a change as a result
          of a subdivision or combination of such shares or a change in par
          value, as aforesaid), or in the case of a sale or conveyance to
          another corporation of the property of the Company as an entirety, the
          Holder of this Warrant shall thereafter have the right to purchase
          upon the exercise of this Warrant the kind and number of shares of
          stock and other securities and property receivable upon such
          reclassification, change, consolidation, merger, sale or conveyance 
          as if the Holder were the owner of the Common Shares underlying this
          Warrant immediately prior to any such events at the Purchase Price in
          effect immediately prior to the record date for such reclassification,
          change, consolidation, merger, sale or conveyance as if such Holder
          had exercised this Warrant.


6.   EXCHANGE AND REPLACEMENT OF WARRANT

     This Warrant is exchangeable without expense, upon the surrender hereof by
     the registered Holder at the principal executive office of the Company for
     new Warrants of like tenor and date representing in the aggregate the right
     to purchase the same number of Common Shares

     as are purchasable hereunder in such denominations as shall be designated

     expenses incidental thereto, and upon surrender and cancellation of this
     Warrant, if mutilated, the Company will make and deliver a new Warrant of
     like tenor, in lieu of this Warrant.

7.   ELIMINATION OF FRACTIONAL INTERESTS

     The Company shall not be required to issue certificates representing
     fractions of Common Shares on the exercise of this Warrant, nor shall it 
     be required to issue scrip or pay cash in lieu of fractional interests, 
     it being the intent of the parties that all fractional interests shall be
     eliminated.

8.   RESERVATION AND LISTING OF SECURITIES

     The Company shall at all times reserve and keep available out of its
     authorized Common Shares, solely for the purpose of issuance upon the
     exercise of this Warrant, such number of Common Shares as shall be issuable
     upon the exercise hereof and thereof.  The Company covenants and agrees
     that, upon exercise of this Warrant and payment of the Purchase Price
     therefor, all Shares issuable upon such exercise shall be duly and validly
     issued, fully paid and non-assessable. 

9.   NOTICES

                                    WARRANT

                           SI DIAMOND TECHNOLOGY, INC.

                The Transferability of this Warrant is Restricted
                             as Provided in Article 3

     FOR GOOD AND VALUABLE consideration, the receipt of which is hereby 
acknowledged by SI DIAMOND TECHNOLOGY, INC., 3006 Longhorn Boulevard, Austin, 
Texas  78758,  a Texas corporation (the "Company"), Michael Doorey  
("Holder"), is hereby granted the right to purchase, at the initial exercise 
price of $0.25 per share, 100,000 shares of the Company's common stock, $.001 
par value (the "Common Shares").

     Subject to the further terms hereof, this Warrant shall be exercisable 
in whole or in part at any time and from time to time prior to 11:59 p.m. 
(Austin time) on October 29, 1999.  This Warrant shall be exercisable only in 
the event that the exercise is for, at a minimum, the lesser of (i) 10,000 
Common Shares or (ii) the remaining number of Common Shares which the 
registered holder of this Warrant has the right to purchase thereunder.  Upon 
the expiration of the applicable period for exercise of this Warrant, this 
Warrant shall no longer entitle the holder thereof to acquire any shares of 
Common Shares or any other security of the Company.  For the purposes of this 
Warrant, "Affiliates" or "Affiliate" of Holder shall mean any person or 
entity that directly, or indirectly through one or more intermediaries, 
controls, or is controlled by, or is under common control with Holder.  
"Control" in, of or by an Affiliate requires ownership of more than fifty 
percent (50%) of (i) voting stock of a company which issued voting stock, or 
(ii) ownership interest in any enterprise; an entity or person is an 
Affiliate only as long as control exists.

     This Warrant initially is exercisable in whole or part as provided above 
at a price of $0.25 per Share payable by wire transfer of collected funds, 
subject to adjustment as provided in Article 5 hereof.  Upon surrender of 
this Warrant, with the annexed Subscription Form duly executed, together with 
payment of the Purchase Price (as hereinafter defined) for the Common Shares 
purchased, at the offices of the Company, the registered holder of this 
Warrant shall be entitled to receive a certificate or certificates for all 
the Common Shares.

<PAGE>

1.   EXERCISE OF WARRANT

     The purchase rights represented by this Warrant are exercisable at the
     option of the Holder hereof, in whole Common Shares only (but not as to
     fractional Common Shares underlying this Warrant), during any period in
     which this Warrant may be exercised as set forth above.

     If this Warrant is exercised in part only, the Company, upon surrender of
     this Warrant for cancellation, shall execute and deliver a new Warrant of
     like tenor evidencing the right of the holder to purchase the balance of
     the Common Shares purchasable hereunder.

2.   ISSUANCE OF CERTIFICATES

     Upon the exercise of this Warrant, the issuance of certificates for Common
     Shares underlying this Warrant shall be made forthwith (and in any event
     within five business days thereafter) without charge to the Holder hereof
     including, without limitation, any tax which may be payable in respect of
     the issuance thereof, and such certificates shall (subject to the
     provisions of Article 3 hereof) be issued in the name of, or in such names
     as may be directed by, the Holder hereof; provided, however, that the
     Company shall not be required to pay any tax which may be payable in
     respect of any transfer involved in the issuance and delivery of any such
     certificates in a name other than that of the Holder and the Company shall
     not be required to issue or deliver such certificates unless or until the
     person or persons requesting the issuance thereof shall have paid to the
     Company the amount of such tax or shall have established to the
     satisfaction of the Company that such tax has been paid.  The certificates
     representing the Common Shares underlying this Warrant shall be executed on
     behalf of the Company by the manual or facsimile signature of one of the
     present or any future Chairman or President of the Company and any present
     or future Vice President or Secretary of the Company.  Upon transfer of
     this Warrant in whole or in part to an Affiliate of Holder, such transferee
     shall be entitled to all the rights of a Holder hereof.

3.   RESTRICTION ON TRANSFER OF WARRANT AND COMMON SHARES

     The Holder of this Warrant, by its acceptance hereof, covenants and agrees
     that this Warrant and the Common Shares are being acquired as an investment
     and not with a view to the distribution thereof, and that the Warrant may
     not be exercised, and neither the Warrant nor the Shares may be sold,
     transferred, assigned, hypothecated or otherwise disposed of (other than to
     an Affiliate of Holder), in whole or in part unless in the opinion of
     counsel reasonably concurred in by the Company's counsel such transfer is
     in compliance with all applicable securities laws, after which this Warrant
     and the Common Shares shall again be subject to the restrictions contained
     in this Article 3.

          proportionately decreased in the case of subdivision or increased in
          the case of combination.

     5.2. RECLASSIFICATION, CONSOLIDATION, MERGER, ETC.

          In case of any reclassification or change of the outstanding Common
          Shares (other than a change in par value to no par value, or from no
          par value to par value, or as a result of a subdivision or
          combination), or in the case of any consolidation of the Company with,
          or merger of the Company into, another corporation (other than a
          consolidation or merger in which the Company is the surviving
          corporation and which does not result in any reclassification or
          change of the outstanding Common Shares, except a change as a result
          of a subdivision or combination of such shares or a change in par
          value, as aforesaid), or in the case of a sale or conveyance to
          another corporation of the property of the Company as an entirety, the
          Holder of this Warrant shall thereafter have the right to purchase
          upon the exercise of this Warrant the kind and number of shares of
          stock and other securities and property receivable upon such
          reclassification, change, consolidation, merger, sale or conveyance as
          if the Holder were the owner of the Common Shares underlying this
          Warrant immediately prior to any such events at the Purchase Price in
          effect immediately prior to the record date for such reclassification,
          change, consolidation, merger, sale or conveyance as if such Holder
          had exercised this Warrant.


6.   EXCHANGE AND REPLACEMENT OF WARRANT

     This Warrant is exchangeable without expense, upon the surrender hereof by
     the registered Holder at the principal executive office of the Company for
     new Warrants of like tenor and date representing in the aggregate the right

     option of the Holder hereof, in whole Common Shares only (but not as to
     fractional Common Shares underlying this Warrant), during any period in
     which this Warrant may be exercised as set forth above.

     If this Warrant is exercised in part only, the Company, upon surrender of
     this Warrant for cancellation, shall execute and deliver a new Warrant of
     like tenor evidencing the right of the holder to purchase the balance of
     the Common Shares purchasable hereunder.

2.   ISSUANCE OF CERTIFICATES

     Upon the exercise of this Warrant, the issuance of certificates for Common
     Shares underlying this Warrant shall be made forthwith (and in any event
     within five business days thereafter) without charge to the Holder hereof
     including, without limitation, any tax which may be payable in respect of
     the issuance thereof, and such certificates shall (subject to the
     provisions of Article 3 hereof) be issued in the name of, or in such names

     Company shall not be required to pay any tax which may be payable in
     respect of any transfer involved in the issuance and delivery of any such
     certificates in a name other than that of the Holder and the Company shall
     not be required to issue or deliver such certificates unless or until the
     person or persons requesting the issuance thereof shall have paid to the
     Company the amount of such tax or shall have established to the
     satisfaction of the Company that such tax has been paid.  The certificates

     shall be entitled to all the rights of a Holder hereof.

3.   RESTRICTION ON TRANSFER OF WARRANT AND COMMON SHARES

     The Holder of this Warrant, by its acceptance hereof, covenants and agrees
     that this Warrant and the Common Shares are being acquired as an investment
     and not with a view to the distribution thereof, and that the Warrant may
     not be exercised, and neither the Warrant nor the Shares may be sold,
     transferred, assigned, hypothecated or otherwise disposed of (other than to
     an Affiliate of Holder), in whole or in part unless in the opinion of
     counsel reasonably concurred in by the Company's counsel such transfer is

     THE SECURITIES REPRESENTED BY THIS WARRANT MAY NOT BE OFFERED FOR
     SALE, SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT MADE UNDER THE SECURITIES ACT OF 1933, AS

                                    WARRANT

                          SI DIAMOND TECHNOLOGY, INC.

                The Transferability of this Warrant is Restricted
                           as Provided in Article 3

     FOR GOOD AND VALUABLE consideration, the receipt of which is hereby 
acknowledged by SI DIAMOND TECHNOLOGY, INC., 3006 Longhorn Boulevard, Austin, 
Texas  78758,  a Texas corporation (the "Company"), First London Securities 
Corporation  ("Holder"), is hereby granted the right to purchase, at the 
initial exercise price of $0.25 per share, 100,000 shares of the Company's 
common stock, $.001 par value (the "Common Shares").

     Subject to the further terms hereof, this Warrant shall be exercisable 
in whole or in part at any time and from time to time prior to 11:59 p.m. 
(Austin time) on October 29, 1999.  This Warrant shall be exercisable only in 
the event that the exercise is for, at a minimum, the lesser of (i) 10,000 
Common Shares or (ii) the remaining number of Common Shares which the 
registered holder of this Warrant has the right to purchase thereunder.  Upon 
the expiration of the applicable period for exercise of this Warrant, this 
Warrant shall no longer entitle the holder thereof to acquire any shares of 
Common Shares or any other security of the Company.  For the purposes of this 
Warrant, "Affiliates" or "Affiliate" of Holder shall mean any person or 
entity that directly, or indirectly through one or more intermediaries, 
controls, or is controlled by, or is under common control with Holder.  
"Control" in, of or by an Affiliate requires ownership of more than fifty 
percent (50%) of (i) voting stock of a company which issued voting stock, or 
(ii) ownership interest in any enterprise; an entity or person is an 
Affiliate only as long as control exists.

     This Warrant initially is exercisable in whole or part as provided above 
at a price of $0.25 per Share payable by wire transfer of collected funds, 
subject to adjustment as provided in Article 5 hereof.  Upon surrender of 
this Warrant, with the annexed Subscription Form duly executed, together with 
payment of the Purchase Price (as hereinafter defined) for the Common Shares 
purchased, at the offices of the Company, the registered holder of this 
Warrant shall be entitled to receive a certificate or certificates for all 
the Common Shares.

<PAGE>

1.   EXERCISE OF WARRANT

     The purchase rights represented by this Warrant are exercisable at the
     option of the Holder hereof, in whole Common Shares only (but not as to
     fractional Common Shares underlying this Warrant), during any period in
     which this Warrant may be exercised as set forth above.

     If this Warrant is exercised in part only, the Company, upon surrender of
     this Warrant for cancellation, shall execute and deliver a new Warrant of
     like tenor evidencing the right of the holder to purchase the balance of
     the Common Shares purchasable hereunder.

2.   ISSUANCE OF CERTIFICATES

     Upon the exercise of this Warrant, the issuance of certificates for Common
     Shares underlying this Warrant shall be made forthwith (and in any event
     within five business days thereafter) without charge to the Holder hereof
     including, without limitation, any tax which may be payable in respect of
     the issuance thereof, and such certificates shall (subject to the
     provisions of Article 3 hereof) be issued in the name of, or in such names
     as may be directed by, the Holder hereof; provided, however, that the
     Company shall not be required to pay any tax which may be payable in
     respect of any transfer involved in the issuance and delivery of any such
     certificates in a name other than that of the Holder and the Company shall
     not be required to issue or deliver such certificates unless or until the
     person or persons requesting the issuance thereof shall have paid to the
     Company the amount of such tax or shall have established to the
     satisfaction of the Company that such tax has been paid.  The certificates
     representing the Common Shares underlying this Warrant shall be executed on
     behalf of the Company by the manual or facsimile signature of one of the
     present or any future Chairman or President of the Company and any present
     or future Vice President or Secretary of the Company.  Upon transfer of
     this Warrant in whole or in part to an Affiliate of Holder, such transferee
     shall be entitled to all the rights of a Holder hereof.

3.   RESTRICTION ON TRANSFER OF WARRANT AND COMMON SHARES

     The Holder of this Warrant, by its acceptance hereof, covenants and agrees
     that this Warrant and the Common Shares are being acquired as an investment
     and not with a view to the distribution thereof, and that the Warrant may
     not be exercised, and neither the Warrant nor the Shares may be sold,
     transferred, assigned, hypothecated or otherwise disposed of (other than to
     an Affiliate of Holder), in whole or in part unless in the opinion of
     counsel reasonably concurred in by the Company's counsel such transfer is
     in compliance with all applicable securities laws, after which this Warrant
     and the Common Shares shall again be subject to the restrictions contained
     in this Article 3.

          par value to par value, or as a result of a subdivision or
          combination), or in the case of any consolidation of the Company with,

          change of the outstanding Common Shares, except a change as a result

          value, as aforesaid), or in the case of a sale or conveyance to

                                   LEASE AGREEMENT

                                    (Multi-Tenant)


STATE OF TEXAS
COUNTY OF  Travis
         ---------- 

     This Lease Agreement ("this lease"), made and entered into by and between  
Industrial Properties Corporation ("Landlord") and SI Diamond Technology, Inc.
("Tenant");

     1.   Premises and Terms.  In consideration of the obligation of Tenant to
pay rent as provided in this lease, and in consideration of the other terms,
provisions, and covenants of this lease, Landlord hereby demises and leases to
Tenant, and Tenant hereby takes from landlord certain premises described and
delineated on the demising plan contained in Exhibit A attached hereto and
incorporated herein by this reference, situated within a building (the
"Building") located on certain real property (the "Land") within the above-named
County and State and more particularly described as follows:

     Approximately 9,667 square feet of space located at 3006 Longhorn
     Boulevard, Suites 107, 108 and 109, Austin, Travis County, Texas,
     situated on lot 1, block B, resubdivision of Industrial Terrace,
     section 3,

together with the other Improvements erected upon said premises (the said
premises and the Improvements located therein being hereinafter referred to as
the "Premises").

     To Have and to Hold the Premises, subject to the other terms and provisions
of this lease, for a term commencing on June 1, 1998 and ending 60 months
thereafter.  Tenant acknowledges that it has inspected the Premises and accepts
the Premises in their present condition as suitable for the purpose for which
the Premises are leased.  Tenant further acknowledges that no representations as
to the repair of the Premises, nor promises to alter, remodel, or improve the
Premises, have been made by Landlord, except for those expressly set forth in
this lease.  

     2.   Rent.  Tenant agrees to pay to Landlord rent for the Premises, without
deduction, set off, or abatement, for the term, at the rate of Seven thousand
fifty-six dollars and 91/100 **** Dollars ($7,056.91) per month.  One such
monthly installment shall be due and payable on the commencement date recited
above, and a like monthly installment shall be due and payable in advance
without demand on or before the same day of each succeeding month during the
hereby demised term.  However, if such commencement date should be a date other
than the first day of a calendar month, there shall be due and payable on said
commencement date as rent for the balance of the calendar month during which
said commence date shall fall, a sum equal to that portion of the rent for a
full month as herein provided which the number of days from said commencement
date to the end of the calender month during which said commencement date shall
fall bears to the total number of days in such month, and all succeeding
installments of rent shall be payable in advance on or before the first day of
each succeeding calendar month during the term.  In addition, Tenant agrees to
deposit with Landlord on the date hereof the sum of Seven thousand two hundred
fifty and 25/100 Dollars ($7,250.25), which sum shall be held by Landlord,
without obligation for interest, as security for the performance of Tenant's
covenants and obligations under this lease, it being expressly understood and
agreed that such deposit is not an advance rental deposit or a measure of
Landlord's damages in case of Tenant's default.  Upon the occurrence of any
event of default by Tenant, Landlord may, from time to time, without prejudice
to any other remedy provided herein as provided by law, use such fund to the
extent necessary to make good any arrears of rent and any other damage, injury,
expense, or liability caused by such event of default; and Tenant shall pay to
Landlord on demand the amount so applied in order to restore the security
deposit to its original amount.  If there be no event of default by Tenant in
existence, any remaining balance of such deposit shall be returned by Landlord
to Tenant upon expiration of this lease.  Notwithstanding anything contained in
this lease to the contrary, all amounts payable by Tenant to or on behalf of
Landlord under this lease, whether or not expressly denominated 

<PAGE>

as rent, shall constitute rent for the purposes of this lease and for 
purposes of section 502(b)(6) (or comparable provision of any future 
bankruptcy law) of the Federal Bankruptcy Code, 11 U.S.C. Sections 101 et 
seq. (the "Bankruptcy Code").

     3.   Disclaimer of Warranties.  BY EXECUTION OF THIS LEASE, TENANT
ACKNOWLEDGES AND AGREES THAT EXCEPT AS EXPRESSLY SET FORTH IN THIS LEASE,
NEITHER LANDLORD NOR ANY OFFICER, PARTNER, AGENT, EMPLOYEE, OR REPRESENTATIVE OF
LANDLORD MAKES OR HAS MADE ANY WARRANTIES OR REPRESENTATIONS OR ANY KIND OR
CHARACTER, EXPRESS OR IMPLIED, WITH RESPECT TO THE PREMISES, OR ANY PORTION
THEREOF, ITS PHYSICAL CONDITION, INCOME TO BE DERIVED THEREFROM, OR EXPENSES TO
BE INCURRED WITH RESPECT THERETO, ITS FITNESS OR SUITABILITY FOR ANY PARTICULAR
USE, OR ANY OTHER MATTER OR THING RELATING TO OR AFFECTING THE SAME.  THERE ARE
NO ORAL AGREEMENTS, WARRANTIES, OR REPRESENTATIONS COLLATERAL TO OR AFFECTING
THE PREMISES OR ANY PORTION THEREOF, EXCEPT AS MAY BE OTHERWISE EXPRESSLY SET
FORTH IN THIS LEASE.  LANDLORD AND TENANT EACH HEREBY AGREE THAT THE PREMISES
ARE LEASED IN AN AS IS CONDITION WITH ANY AND ALL LATENT OR PATENT DEFECTS.  IN
NO EVENT SHALL TENANT HAVE THE RIGHT TO RECOVER CONSEQUENTIAL DAMAGES.  TENANT
BY EXECUTION OF THIS LEASE, EXPRESSLY AGREES THAT LANDLORD HAS NOT MADE AND DOES
NOT MAKE ANY WARRANTIES WITH RESPECT TO THE PREMISES UPON WHICH AN ACTION UNDER
THE TEXAS DECEPTIVE TRADE PRACTICES ACT COULD BE BASED.

     4.   Use.

     A.   The Premises shall be used, to the extent permitted by applicable law,
only for general office purposes and, to the extent applicable, for the purpose
of receiving, storing, shipping, and selling (other than retail) products,
materials, and merchandise made and/or distributed by Tenant and for such other
lawful purposes as may be incidental thereto.  Tenant shall at its own cost and
expense obtain and at all times maintain any and all licenses and permits
necessary for  any such use.  Tenant shall comply with all governmental laws,
ordinances, and regulations applicable to the use of the Premises by tenant and
shall promptly comply with all governmental orders and directives for the
correction, prevention, and abatement of nuisances in, upon, or connected with
the use of the Premises by tenant all at Tenant's sole expense.  Without
Landlord's prior written consent, Tenant shall not receive, store, or otherwise
handle any product, material, or merchandise which is explosive or highly
inflammable or any material which may be corrosive or otherwise damaging to the
Premises or any appurtenances thereto.  Tenant will not, without Landlord's
approval, permit the Premises to be used for any purpose which would render the
insurance thereon void or the insurance risk more hazardous or the premiums
therefor more expensive.  In the event any such use of the Premises, or any part
thereof, whether approved by Landlord or not, shall ever cause the insurance
rates for policies carried by Landlord to increase, Tenant shall pay on demand
from Landlord, as additional rent, the full amount by which such insurance rates
increased solely as a result of Tenant's use, without regard to whether such
policy covers areas other than the Premises so long as such other covered areas
are adjacent thereto or otherwise affected by Tenant's hazardous use.  Further,
Tenant will not introduce into the Premises or use therein any equipment or
fixtures which might be reasonably expected, due to excess weight, vibration, or
any other characteristic, to cause damage to the Premises or undue interference
with the occupancies of adjacent premises.  Additionally, Tenant shall not store
any products, materials, or merchandise outside the exterior walls or interior
demising walls of the Premises without Landlord's prior written consent.

     B.   Without limiting the generality of the provisions of Paragraph 4.A
above, Tenant expressly agrees that (I) no activity will be conducted on the
Premises that will use or produce any "Hazardous Substance" (as hereinafter
defined), except for such activities as are part of the ordinary course of
Tenant's business activities (the "Permitted Activities"), provided said
Permitted Activities are at all times conducted in accordance with all
Environmental Laws and further provided that the Permitted Activities have been
approved in advance in writing by Landlord which approval shall not be
unreasonably withheld or delayed after disclosure to Landlord by Tenant of the
Hazardous Substances involved; (II) the Premises will not be used in any manner
for the storage of any Hazardous Substances except for the temporary storage of
such materials as are used in the ordinary course of Tenant's business (the
"Permitted Materials"), provided such Permitted Materials are at all times
properly stored in a manner and 


                                       2
<PAGE>

location meeting all Environmental Laws and further provided that the storage 
of such Hazardous Substances is approved which approval shall not be 
unreasonably withheld or delayed in advance in writing by Landlord after 
disclosure to Landlord by Tenant of the Hazardous Substances involved; (III) 
no portion of the Premises will be used as a landfill or a dump; (IV) Tenant 
will not install any underground tanks of any type on the Premises or the 
Land; (V) Tenant will not permit any Hazardous Substances to be brought onto, 
stored, processed, disposed of on, released, discharged from (including 
ground water contamination) or otherwise handled on the Premises, except for 
the Permitted Materials which are used and disposed of (at a location other 
than on the Land or Premises) in accordance with Environmental Law, and if so 
brought or found located thereon, the same shall be immediately removed by 
Tenant, at Tenant's sole cost and expense, with proper disposal (at a 
location other than on the Land or Premises), and all required cleanup 
procedures shall be diligently undertaken by Tenant pursuant to all 
Environmental Laws.  Landlord may condition any approval of Permitted 
Activities or of Permitted Materials on compliance with such  terms and 
conditions as Landlord may reasonably deem appropriate, and may refuse to 
grant its approval if the purposed Permitted Activities or the proposed 
Permitted Materials require a permit, license, registration, hazardous waste 
generator identification number, or other filing or approval under any 
Environmental Law, or if, in Landlord's reasonable judgment, the propose 
Permitted Activities or the proposed Permitted Materials would pose any 
material adverse risk [see addendum 1].  Tenant shall immediately notify 
Landlord should Tenant become aware of any Hazardous Substance or other 
environmental problem or liability with respect to the Premises.  Reasonable 
amounts of copy machine toners and other normal office supplies as reasonably 
necessary for the conduct of Tenant's regular office functions within the 
Premises shall be considered Permitted Materials, and the normal use of such 
office supplies and materials in the conduct of normal office operations 
shall be considered Permitted Activities.  For purposes of this lease 
"Hazardous Substances" means any substance (i) the presence of which requires 
removal, remediation, or investigation under any Environmental Law, (ii) that 
is defined or classified as a hazardous waste, hazardous material, pollutant, 
contaminant, or toxic or hazardous substance under any Environmental Law, 
including without limitation, any hazardous substance within the meaning of 
Section 101(14) of the Comprehensive Environmental Response, Compensation, 
and Liability Act, as amended, 42 U.S.C. Section 9601(14), or (iii) that 
contains or consists of gasoline, diesel fuel, oil, fuel oil, or other 
petroleum hydrocarbons.  Tenant shall indemnify and hold Landlord (and any 
mortgagee and trustee under any deed of trust or mortgage on the Premises) 
harmless from all claims, demands, actions, liabilities, costs (including 
attorney's fees), expenses, damages and obligations of any nature arising 
from or as a result of the use of the Premises by Tenant, its invitees, 
agents, contractors or employees in violation of the foregoing provision 
relating to Hazardous Substances.  The foregoing indemnification shall 
survive the termination or expiration of this lease.

     5.   Taxes.

     A.   Subject to the provisions of Paragraph 5.B, Landlord agrees to pay
before they become delinquent all taxes, assessments (both general and special),
or governmental charges (hereinafter collectively referred to as "taxes")
lawfully levied or assessed against the Premises or any part thereof; provided,
however, Landlord may, at its sole cost and expense (in its own name or in the
name of both Landlord and Tenant as Landlord may deem appropriate) dispute and
contest the same, and in such case such disputed item need not be paid until
finally adjudged to be valid and any right to appeal has lapsed.  At the
conclusion of such contest, Landlord shall pay the items contested to the extent
that they are held valid, together with all items, court costs, interest, and
penalties relating thereto.

     B.   The maximum amount of taxes levied or assessed against the Premises
during any one real estate tax year to be paid by Landlord shall be those taxes
levied or assessed during the 1997 real estate tax year (the "maximum tax
amount").  If in any real estate tax year during the term, or any renewal or
extension, the taxes levied or assessed against the Building and Land are in an
amount which causes the portion thereof allocable to the Premises to exceed the
maximum tax amount, Landlord shall notify Tenant of the amount of taxes actually
paid by Landlord for such tax year, and the amount of the excess which is
payable by Tenant which excess shall be prorated between Tenant and all other
tenants of the Building based on Tenant's Share (hereinafter defined).  Tenant
shall pay to Landlord on or before the payment date set forth in such notice
(which date shall be not less than ten (10) days from 


                                       3
<PAGE>

the date of such notice), as additional rent, the amount of such excess; and 
the failure to pay such excess when due shall be treated as a failure to make 
payment of rent when due. Any payment to be made pursuant to this Paragraph 
5.B with respect to the real estate tax year in which this lease commences or 
terminates shall bear the same ratio to the payment which would be required 
to be made for the full tax year as that part of such tax year covered by the 
term of this lease bears to a full tax year.  Landlord's real estate tax 
statements with respect to the Premises shall be made available for 
inspection by Tenant At Landlord's offices during Landlord's business hours.

     6.   Landlord's Repair and Common Area Obligations.

     A.   Landlord shall at its expense maintain only the roof, foundation, and
the structural soundness of the exterior walls of the Building in good repair,
reasonable wear and tear excepted.  Tenant shall repair and pay for any damage
caused by the negligence or willful misconduct of Tenant, or Tenant's employees,
agents, or invitees, or caused by Tenant's default hereunder.  The term "walls"
as used herein shall not include windows, glass or plate glass, doors, or
special store fronts.  Tenant shall promptly give Landlord written notice of any
defect or need for repairs, after which Landlord shall have a reasonable
opportunity to repair same or cure such defect.  Landlord's liability hereunder
shall be limited to the cost of such repairs or curing such defect.  In the
event the Premises have air conditioning installed therein on the date of this
lease, then Landlord represents that on the commencement date of this lease such
air-conditioning system shall be in good operating condition; provided, however,
that during the term of this lease Tenant shall at its own cost and expense
maintain such system in good operating condition, shall make all necessary
repairs, and upon termination of this lease shall deliver such system to
Landlord in good operating condition, ordinary wear and tear excepted.

     B.   Subject to the provisions of Paragraph 6.C, Landlord shall take
reasonable care of the grounds around the Building including exterior lighting,
mowing of grass, care of shrubs and trees, and general landscaping and will keep
the parking areas, driveways, and alleys in a reasonably clean, usable, and
sanitary condition.

     C.   In addition to and separate from the rent payable under Paragraph 2,
Tenant shall pay to Landlord Tenant's Share (hereinafter defined) of Maintenance
and Use Charge (as hereinafter defined), as adjusted from time to time, pursuant
to the provisions hereinafter stated.  For purposes of this lease, the following
terms shall have the hereinafter indicated meanings:

          (a)  The phrase "Maintenance and Use Charge" shall mean, for each
     calendar year (or portion thereof) during the term of this lease, the
     aggregate of all costs, expenses and liabilities of every kind or nature
     paid or incurred by Landlord in connection with the performance of its
     obligations under Paragraph 6.B.  In no event shall the phrase "Maintenance
     and Use Charge" include any expenditure of cost attributable to capital
     improvements or capital maintenance items.

          (b)  The term "Tenant's Share" shall refer to a fraction, the
     numerator of which is the floor area (in square feet) of the Premises and
     the denomination of which is the aggregate leaseable floor area (in square
     feet) in all buildings (including the Building) now or hereafter situated
     on the Land as of the first day of January for the relevant calendar year;
     Landlord and Tenant hereby stipulate that Tenant's Share is 19.3%.

     D.   Monthly during the first year of the term of this lease, Tenant will
pay Landlord the sum of $193.34 per month, monthly in advance, as an initial
estimate of the Maintenance and Use Charge payable at the same time and place as
the rent is payable; provided, however, if the lease term does not begin on the
first day of a calendar month, Tenant shall pay a pro rata portion of such sum
for such partial month; such applicable amount being herein referred to as the
"Estimated Charge."  Landlord shall have the right to adjust such monthly
estimate on an annual basis pursuant to Paragraph 6.E hereof.


                                       4
<PAGE>

     E.   At the end of each calendar year occurring during the term of this
lease (and subsequent to the expiration or other termination of this lease if
such occur on a date other than the last day of a calendar year), Landlord will
give Tenant notice of the total amount(s) paid by Tenant for the relevant
calendar year together with the actual amount of Tenant's Share of the
Maintenance and Use Charge for such calendar year.  If the actual amount of
Tenant's Share of the Maintenance and Use Charge with respect to such period
exceeds the aggregate amount(s) previously paid by Tenant with respect thereto
during such period, Tenant shall pay to Landlord the deficiency within ten (10)
days following notice from Landlord.  However, if the aggregate amount(s)
previously paid by Tenant with respect thereto exceeds Tenant's Share of the
Maintenance and Use Charge for such period, then, at Landlord's election, such
surplus (net of any amounts then owing by Tenant to Landlord) shall be credited
against the next ensuing installment of the Maintenance and Use Charge due
hereunder by Tenant, or Landlord may refund such net surplus to Tenant within
thirty (30) days following Landlord's calculation of Tenant's Share of the
Maintenance and Use Charges with respect to each calendar year.  Landlord shall
be entitled to adjust, in its reasonable discretion, the Estimated Charge, such
adjusted Estimated Charge to be payable on the first day of the second calendar
month immediately following Landlord's notice of such adjustment and to remain
in effect until further notice from Landlord.

     7.   Tenant's Repairs.  Tenant shall, at its own cost and expense, keep all
other parts of the Premises, including but not limited to, windows, glass and
plate glass, doors (including overhead doors), any special store front, interior
walls and finish work, floors and floor covering, heating, ventilating and 
air-conditioning systems, gutters, downspouts and protective posts therefor, 
curbs, dock boards, dock bumpers, dock levelers, steps and landings, plumbing 
work and fixtures, and gas, electric, water, and other utility lines, in good 
condition and repair, ordinary wear and tear excepted, and shall take good 
care of the Premises and its fixtures and suffer no waste.  Tenant shall keep 
the Premises free of all pest infestation, including, but not limited to, 
termites and rodents, and shall maintain a regular pest control prevention 
program.  Except as set forth in the last sentence of this Paragraph 7, 
Tenant shall not be obligated to repair any damage caused by fire, tornado, 
or other casualty covered by items set forth under the extended coverage 
provisions of Landlord's fire insurance policy.  In the event the Premises 
are served by rail track or spur track, then Tenant, notwithstanding the 
provisions of any rail track agreements to the contrary, shall be liable and 
responsible for maintaining, or reimbursing the rail carrier for the 
maintenance of, the portion of the track and related facilities adjacent to 
the Premises.  Tenant shall also be obligated to repair any damage to the 
Premises or any part thereof caused by the negligent Act or willful 
misconduct of Tenant, its agents, customers, employees, or invitees 
regardless of whether Tenant would otherwise be obligated to make such repair 
by the provisions hereof.

     8.   Alterations.  Tenant shall not make any major alterations, additions,
or improvements to the Premises without the prior written consent of Landlord,
which consent shall not be unreasonably withheld or delayed.  Tenant may,
without the consent of Landlord, but at Tenant's own cost and expense and in a
good, workmanlike manner, make such minor alterations, additions, or
improvements or erect, remove, or alter such partitions, or erect such shelves,
bins, machinery, and trade fixtures as it may deem advisable, without altering
the basic character of the Building or improvements, without affecting the
structural or loadbearing elements of the Building or improvements, without
overloading or damaging such Building or improvements or any utility systems
servicing same, and without interference to the other occupants of the Building
or any other of Landlord's tenants, and in each case complying with all
applicable governmental laws, ordinances, regulations, and other requirements. 
At the termination of this lease, Tenant shall, if Landlord so elects, and at
Tenant's sole cost and expense, remove all alterations, additions, improvements,
and partitions erected by Tenant and restore the Premises to their original
condition; otherwise, such improvements shall be delivered to Landlord with the
Premises.  All shelves, bins, machinery, and trade fixtures installed by Tenant
may be removed by Tenant at the termination of this lease, if Tenant so elects,
so long as no event of default by Tenant is then in existence, and shall be
removed if required by Landlord.  All such removals and restorations shall be
accomplished in a good, workmanlike manner so as not to damage the primary
structure or structural qualities of the Building and other improvements
situated on the Premises.  Any fixtures installed in the Premises by Tenant
other than shelves, bins, machinery, and similar trade fixtures shall become the
property of Landlord when installed.


                                       5
<PAGE>

     9.   Signs.  Tenant shall have the right to install signs upon the exterior
of the Building and other improvements situated on the Premises only when first
approved in writing by Landlord, which approval shall not be unreasonably
withheld or delayed, and subject to any applicable governmental laws,
ordinances, regulations, and other requirements and subject to applicable
restrictive covenants, if any.  Tenant shall remove all such signs at the
termination of this lease.  Such installations and removals shall be made in
such manner as to avoid injury or defacements of the Building and other
improvements situated on the Premises.

     10.  Inspection.  Landlord and Landlord's agents and representatives shall
have the right to enter and inspect the Premises at any time during reasonable
business hours for the purpose of ascertaining the condition of the Premises or
in order to make such repairs as may be required to be made by Landlord under
the terms of this lease and for the purpose of showing the Premises and the
Building to prospective purchasers.  During the period that is six (6) months
prior to the end of the term hereof, Landlord and Landlord's agents and
representatives shall have the right to enter the Premises at any time during
reasonable business hours for the purpose of showing the Premises to prospective
tenants and shall have the right to erect on the Premises a suitable sign
indicating that the Premises are for sale or lease.

     11.  Utilities.  Landlord agrees to provide such water, electricity,
telephone, and other utility service connections into the Premises as may be
presently in place.  Tenant shall pay all charges incurred for any utility
services used on or from the Premises and any maintenance charges for utilities,
shall be responsible for any costs associated in any manner with any additional
utility connections to the Premises which Tenant may require, and shall furnish
all electric light bulbs and tubes.  Such payments shall be made directly to the
supplier of any utility separately metered (or submetered) to the Premises, or
to Landlord, if any such utilities are not separately submetered or metered. 
Landlord shall calculate the cost of Tenant's share of any such utilities on
such equitable basis as may be determined by Landlord with respect to any such
utilities.  Landlord shall in no event be liable for any interruption or failure
of utility services on the Premises.

     12.  Assignment and Subletting.

     A.   Tenant shall not have the right to assign this lease or to sublet the
whole or any part of the Premises without the prior written consent of Landlord,
which consent shall not be unreasonably withheld.  Notwithstanding any
assignment or subletting, Tenant shall at all times remain fully responsible and
liable for the payment of the rent herein specified and for compliance with all
of the other obligations imposed on Tenant under the terms, provisions, and
covenants of this lease.  Upon the occurrence of an "event of default" as
hereinafter defined, if the Premises or any part thereof are then assigned or
sublet, Landlord, in addition to any other remedies herein provided, or provided
by law, may at its option collect directly from such assignee or subtenant all
rents or payments becoming due to Tenant under such assignment or sublease and
apply such rent or payment against any sums due to Landlord by Tenant.  No such
collection shall be construed to constitute a novation of a release of Tenant
from the further performance of its obligations under this lease.  Landlord
shall have the right to assign any of its rights under this lease.

     B.   If Tenant is a corporation, then any transfer of this lease from
Tenant by merger, consolidation or dissolution or any change in ownership or
power to vote a majority of the voting stock in Tenant outstanding at the time
of execution of this instrument (or at any future time) shall constitute an
assignment for the purpose of this lease; provided, however, that acquisition of
all stock of a corporate Tenant by any corporation, the stock of which is listed
on either the New York or American Stock Exchange, or the merger of a corporate
Tenant into such a corporation, the stock of which is so listed, shall not
itself be deemed to be a violation of Paragraph 12 hereof.  For purposes of this
Paragraph 12.B, the term "voting stock" shall refer to shares of stock regularly
entitled to vote for the election of directors of the corporation involved.


                                       6
<PAGE>

     C.   If Tenant is a general partnership having one or more corporations as
partners or if Tenant is a limited partnership having one or more corporations
as general partners, the provision of the preceding Paragraph 12.B shall apply
to each of such corporations as if such corporation alone had been the Tenant
hereunder.

     D.   If Tenant is a general partnership, then the transfer of a majority of
the partnership interest of Tenant existing at the time of execution of this
instrument (or at any future time) shall constitute an assignment for the
purpose of this lease.  If Tenant is a limited partnership, then the assignment
of all or any portion of the interest of a general partner of Tenant shall
constitute an assignment for the purpose of this lease.

     13.  Fire and Casualty Damage.

     A.   If the Premises should be damaged or destroyed by fire, tornado, or
other casualty, Tenant shall give immediate written notice thereof to Landlord.

     B.   If the Premises or the Building should be totally destroyed by fire,
tornado, or other casualty, or if the premises should be so damaged that
rebuilding or repairs cannot be completed within 200 days after the date upon
which Landlord is notified by Tenant of such damage, this lease shall terminate
and the rent shall be abated during the unexpired portion of this lease,
effective upon the date of the occurrence of such damage.

     C.   If the Premises or the Building should be damaged by fire, tornado, or
other casualty, but only to such extent that rebuilding or repairs can be
complete within 120 days after the date upon which Landlord is notified by
Tenant of such damage, this lease shall not terminate, but Landlord shall, at
its sole cost and expense, proceed with reasonable diligence to rebuild and
repair such Building to substantially the condition in which it existed prior to
such damage, except that (i) Landlord shall not be required to so rebuild or
repair if less than twelve (12) months remain in the term hereof after the
expiration of such 120 day period, (ii) Landlord shall not be required to
rebuild, repair, or replace any part of the partitions, fixtures, and other
improvements which may have been placed on the Premises by Tenant, and (iii) so
long as Landlord has complied with the provisions hereof relating to insurance
coverage.  Landlord shall not be obligated to expend any funds in excess of
available insurance proceeds attributable to such damage in rebuilding the
Premises.  If the Premises are untenantable in whole or in part following such
damage, the rent payable hereunder during the period the Premises are
untenantable shall be reduced to such extent as may be fair and reasonable under
all of the circumstances.  In the event that Landlord should fail to complete
such repairs and rebuilding within 120 days after the date upon which Landlord
is notified by Tenant of such damages, Tenant may, at its option, terminate this
lease by delivering written notice of termination to Landlord within thirty (30)
days after the expiration of such 120-day period, as Tenant's exclusive remedy,
whereupon all rights and obligations hereunder shall cease and determine.

     D.   Notwithstanding anything herein to the contrary, in the event the
holder of any indebtedness secured by a mortgage or deed of trust covering the
Premises requires that the insurance proceeds be applied to such indebtedness,
then Landlord shall have the right to terminate this lease by delivering written
notice of termination to Tenant, whereupon all rights and obligations hereunder
shall cease and determine.

     E.   Any insurance which may be carried by Landlord or Tenant against loss
or damage to the buildings and other improvements situated on the Premises shall
be for the sole benefit of the party carrying such insurance and under its sole
control.

     F.   Each of Landlord and Tenant hereby releases the other from any and all
liability or responsibility to the other or anyone claiming through or under
them by way of subrogation or otherwise for any loss or damage to property
caused by fire or any of the extended coverage casualties covered by the
insurance maintained hereunder, even if such fire or other casualty shall have
been caused by the fault or negligence of the other party, or anyone for whom
such party may be responsible; provided, however, that this release shall be
applicable and in force and effect only with respect to loss or damage occurring
during such time as the releaser's policies contain a clause or 


                                       7
<PAGE>

endorsement to the effect that any release shall not adversely affect or 
impair said policies or prejudice the right of the releaser to recover 
thereunder.  Each of Landlord and Tenant agrees that it will request its 
insurance carriers to include in its policies such a clause of endorsement.

     G.   Landlord covenants and agrees to maintain standard fire and extended
coverage insurance covering the Building (exclusive of any of Tenant's fixtures,
furnishings, and equipment attached thereto or located thereon) in an amount not
less than eighty percent (80%) of the replacement cost thereof.  If during the
second full lease year after the commencement date of this lease, or during any
subsequent year of the primary term or any renewal or extension, the insurance
premiums for the fire and extended insurance carried by Landlord shall exceed
the premiums for such insurance for the first full lease year of the term
hereof, Tenant shall pay to Landlord, within fifteen (15) days after receipt by
Tenant of notice of the amount thereof, as additional rent, Tenant's Share of
the amount of such excess; and the failure to pay Tenant's Share of such excess
upon demand shall be treated in the same manner as a failure to make payment of
rent when due.

     14.  Liability.  Landlord shall not be liable to Tenant or Tenant's
employees, agents, patrons, or visitors, or to any other person whomsoever, for
any injury to person or damage in property on or about the Premises caused by
the negligence or misconduct of Tenant, its agents, servants, or employees, or
of any other person entering upon the Premises or caused by the Building and
improvements located on the Premises becoming out of repair, or caused by
leakage of gas, oil, water, or steam or by electricity emanating from the
Premises, or due to any cause whatsoever, and Tenant agrees to indemnify
Landlord and hold it harmless from any loss, expense, or claims, including
attorneys' fees, arising out of any such damage or injury; except that any
injury to person or damage to property caused by the gross negligence of
Landlord or by the failure of Landlord to repair and maintain that part of the
Premises which Landlord is obligated to repair and maintain within a reasonable
time after the receipt of written notice from Tenant of needed repairs or
defects shall be the liability of Landlord and not of Tenant.  Tenant shall
procure and maintain throughout the terms of this lease a policy or policies of
insurance, at its sole cost and expense, insuring both Landlord and Tenant
against all claims, demands or actions arising out of or in connection with
Tenant's use or occupancy of the Premises, or by the condition of the Premises,
the limits of such policy or policies to be in an amount not less than
$1,000,000 in respect of any one occurrence and a General Aggregate limit of
$2,000,000, and to be written by insurance companies qualified to do business in
the state in which the Premises are located.  Such policies or duly executed
certificates of insurance shall be promptly delivered to Landlord and renewals
thereof as required shall be delivered to Landlord at least ten (10) days prior
to the expiration of the respective policy terms.  All such policies shall
contain provisions requiring that the insurer give Landlord not less than thirty
(30) days' prior written notice of the cancellation of such policies.

     15.  Condemnation.

     A.   If the whole or any substantial part of the Premises or the Building
or Land upon which the Premises are located should be taken for any public or
quasi-public use under governmental law, ordinance, or regulation, or by right
of eminent domain, or by private purchase in lieu thereof, this lease shall
terminate and the rent shall be abated during the unexpired portion of this
lease, effective when the physical taking of said Premises shall occur.  For the
purposes hereof, "substantial part of the Premises" shall be deemed to mean such
portion of the Premises the loss of which would, in Landlord's reasonable
opinion, materially lessen the usefulness of the Premises to Tenant for the
purposes for which Tenant is then using the Premises.

     B.   If less than a substantial part of the Premises or the Building or
Land upon which the Premises are located shall be taken for any public or 
quasi-public use under any governmental law, ordinance, or regulation, or by 
right of eminent domain, or by private purchase in lieu thereof, this lease 
shall terminate but the rent payable hereunder during the unexpired portion 
of this lease shall be reduced to such extent as may be fair and reasonable 
under all of the circumstances.


                                       8
<PAGE>

     C.   In the event of any such taking or private purchase in lieu thereof,
Landlord and Tenant shall each be entitled to receive and retain such separate
awards and/or portion of lump sum awards as may be allocated to their respective
interests in any condemnation proceedings.

     16.  Holding Over.  Should Tenant, or any of its successors in interest,
hold over the Premises, or any part thereof, after the expiration of the term of
this lease, as may be renewed or extended, unless otherwise agreed in writing,
such holding over shall constitute and be construed as creating a month-to-month
tenancy only, cancellable at the will of Landlord, at a rental equal to the
greater of (a) the then fair market rental value of the Premises or (b) the
total rental payable for the last month of the term hereof plus fifty percent
(50%) of such amount, payable in full on the first day on which Tenant holds
over and on the first day of each month thereafter during such holdover period.
The inclusion of the preceding sentence shall not be construed as Landlord's
permission for Tenant to hold over.

     17.  Quiet Enjoyment.  Landlord covenants that it now has, or will acquire
before Tenant takes possession of the Premises, good title to the Premises, free
and clear of all liens and encumbrances, excepting only the lien for current
taxes not yet due, such mortgage or mortgages as are permitted by the terms of
this lease, zoning ordinances, and other building and fire ordinances and
governmental regulations relating to the use of such property, and easements,
restrictions and other conditions of record.  In the event this lease is a
sublease, then Tenant agrees to take the Premises subject to the provisions of
the prior leases.  Landlord represents and warrants that it has full right and
authority to enter into this lease and that Tenant, upon paying the rental and
performing its other covenants and agreements under the terms of this lease,
shall peaceably and quietly have, hold, and enjoy the Premises for the term
hereof without hindrance or molestation from Landlord, or anyone claiming by,
through, or under Landlord, but not otherwise, subject to the terms and
provisions of this lease.

     18.  Events of Default.  The following events shall be deemed to be events
of default by Tenant under this lease:

          (a)  Tenant shall fail to pay any installment of the rent or
     additional rent hereby reserved (including, without limitation, amounts
     payable pursuant to Paragraphs 4, 5, 6, 11, and 13 hereof) or shall fail to
     perform or discharge any other obligation or liability of Tenant under this
     lease requiring the payment of money when any such payment is due.

          (b)  Tenant shall become insolvent, or shall make a transfer in fraud
     of creditors, or shall make an assignment for the benefit of creditors.

          (c)  Tenant shall file a petition under any section or chapter of the
     Bankruptcy Code or under any present or future bankruptcy, insolvency, or
     similar law or statute of the United States or any state thereof heretofore
     or hereinafter enacted; or Tenant shall have such a petition filed against
     it involuntarily and such petition is not withdrawn or otherwise removed
     within sixty (60) days of its being filed; or Tenant shall be adjudged
     bankrupt or insolvent in proceedings filed against Tenant thereunder.

          (d)  A receiver, trustee, or custodian shall be appointed for, or
     shall take possession of, all or substantially all of the assets of Tenant.

          (e)  Tenant shall abandon or vacate any substantial portion of the
     Premises.

          (f)  Tenant shall fail to comply with any term, provision, or covenant
     of this lease or shall fail to discharge any obligation or liability
     hereunder not involving the payment of money, and shall not cure any such
     failure within ten (10) days after written notice thereof to Tenant,
     provided that if such default is not susceptible to cure within ten (10)
     days, Tenant shall be deemed to have cured such default if Tenant has


                                       9
<PAGE>

     commenced efforts to cure such default within such ten (10) day period and
     diligently pursues and completes such curative actions within a reasonably
     prompt period of time thereafter.

     19.  Remedies.  Upon the occurrence of any of such events of default
described herein, Landlord shall have the option to pursue any one or more of
the following remedies without any notice or demand whatsoever (Tenant hereby
expressly waiving any such notice or demand):

          (a)  Terminate this lease, in which event Tenant shall immediately
     surrender the Premises to Landlord without any payment therefor, and if
     Tenant fails so to do, Landlord may, without prejudice to any other remedy
     which it may have for possession or arrearages in rent, enter upon and take
     possession of the Premises and expel or remove Tenant and any other person
     who may be occupying such Premises or any part thereof, by any lawful
     means, whether through judicial process or otherwise, and including the
     lawful use of force, if necessary, without being liable for prosecution or
     any claim of damages thereof; and Tenant agrees to pay to Landlord on
     demand the amount of all loss and damage which Landlord may suffer by
     reason of such termination, whether through inability to relet the Premises
     on satisfactory terms or otherwise.

          (b)  Enter upon and take possession of the Premises and expel or
     remove Tenant and any other person who may be occupying such Premises or
     any part thereof, by any lawful means, whether through judicial process or
     otherwise, and including the lawful use of force, if necessary, without
     being liable for prosecution or any claim for damages therefor, and relet
     the Premises, in the name of Landlord or otherwise, for such term or terms
     (which may be greater or lesser than the period which would otherwise have
     constituted the balance of the term of this lease) and on such conditions
     (which may include concessions as Landlord, in its sole discretion, may
     determine, and receive the rent therefor.  In the event of any such 
     re-entry or dispossession, Tenant shall not thereby be relieved of its
     liability and obligations under this lease, which shall survive any such
     re-entry or dispossession, and in that event (i) the rent and other charges
     required to be paid by Tenant up to the time of such re-entry or
     dispossession shall become due and payable, together with such reasonable
     expense as Landlord may incur for reasonable attorneys' fees, brokerage
     commissions, and/or expenses of putting the Premises in such condition as
     the Tenant under the provisions hereof is required to maintain, or for
     preparing the same for reletting and (ii) Tenant or the legal
     representatives of Tenant shall also pay Landlord, as liquidated damages
     for the failure of Tenant to observe and perform Tenant's covenants herein
     contained, an amount equal to the sum of (A) the base rental set forth in
     Paragraph 2 hereof and (B) all additional rental payable by Tenant under
     the provisions hereof, as if this lease were still in effect less the net
     amount, if any, of the rents and all other amounts collected on account of
     the lease or leases of the Premises for each month of the period which
     would otherwise have constituted the balance of the term of this lease as
     the same may theretofore have been extended.  In computing the amount of
     such liquidated damages there shall be included such expenses as Landlord
     may incur in connection with reletting, including reasonable attorneys'
     fees, brokerage commissions, expenses of keeping the Premises in the
     condition Tenant is required to maintain under the provisions of this
     lease, or expenses of preparing the same for reletting.  Any such
     liquidated damages shall be paid in monthly installments by Tenant on the
     day specified hereunder, and any suit brought to collect the amount of the
     deficiency of any month shall not prejudice in any way the right of
     Landlord to collect the deficiency for any subsequent month by a similar
     proceeding.

          (c)  Enter upon the Premises by any lawful means, whether through
     judicial process or otherwise, and including the lawful use of force, if
     necessary, without terminating this lease and without being liable for
     prosecution or any claim for damages therefor, and do whatever Tenant is
     obligated to do under the terms of this lease; and Tenant agrees to
     reimburse Landlord on demand for any expenses which Landlord may incur in
     thus effecting compliance with Tenant's obligations under this lease, and
     Tenant further agrees that Landlord shall not be liable for any damages
     resulting to Tenant from such action, whether caused by the negligence of
     Landlord or otherwise.


                                      10

In the event Tenant fails to pay any installment of rent or additional rent
hereunder within five (5) days after such installment is due, Tenant shall pay
to Landlord on demand a late charge in an amount equal to ten percent (10%) of
such installment; and the failure to pay such amount within ten (10) days after
demand therefor shall be an event of default hereunder.  The provision for such
late charge shall be in addition to all of Landlord's other rights and remedies
hereunder or at law and shall not be construed as liquidated damages or as
limiting Landlord's remedies in any manner.

     Pursuit of any of the foregoing remedies shall not preclude pursuit of any
of the other remedies herein provided or any other remedies provided by law, nor
shall pursuit of any remedy herein provided constitute a forfeiture or waiver of
any rent due to Landlord hereunder or of any damages accruing to Landlord by
reason of the violation of any of the terms, provisions, and covenants herein
contained.  No waiver by Landlord of any violation or breach of any of the
terms, provisions, and covenants herein contained shall be deemed or construed
to constitute a waiver of any other violation or breach of any of the terms,
provisions, and covenants herein contained.  Landlord's acceptance of the
payment of rental or other payments hereunder after the occurrence of an event
of default shall not be construed as a waiver of such default, unless Landlord
so notifies Tenant in writing.  Forbearance by Landlord to enforce one or more
of the remedies herein provided upon an event of default shall not be deemed or
construed to constitute a wavier of such default.  If, on account of any breach
or default by Tenant in Tenant's obligations under the terms and conditions of
this lease, it shall become necessary or appropriate for Landlord to employ or
consult with an attorney concerning, or to enforce or defend, any of Landlord's
rights or remedies hereunder, Tenant agrees to pay any reasonable attorneys'
fees.  No act or thing done by the Landlord or its agents during the term hereby
granted shall be deemed an acceptance of the surrender of the Premises and no
agreement to accept the surrender of said Premises shall be valid unless in
writing signed by Landlord.  The receipt by Landlord of rent with knowledge of
the breach of any covenant or other provision contained in this lease shall not
be deemed or construed to constitute a waiver of any other violation or breach
of any of the terms, provisions, and covenants contained herein.

     20.  Mortgages.  Tenant accepts this lease subject and subordinate to any
mortgage(s) and/or deed(s) of trust now or at any time hereafter constituting a
lien or charge upon the Premises or the improvements situated thereon or any
portion thereof.  Tenant shall at any time hereafter on demand execute any
instruments, releases or other documents which may be required by any mortgagee
for the purpose of subjecting and subordinating this lease to the lien of any
such mortgage.  With respect to any mortgage(s) and/or deed(s) of trust at any
time hereafter created which constitute a lien or charge upon the Premises or
the improvements situated thereon, Landlord agrees to request the holder of such
mortgage to enter into a non-disturbance and attornment agreement with Tenant
providing for such lender to honor this lease and Tenant's interest in the
Premises so long as Tenant is not in default hereunder.  However, Landlord makes
no warranty that any such agreement is obtainable, and Tenant's obligation to
subordinate this lease to any such mortgage shall not be dependent upon the
execution of any such agreement.

     21.  Landlord's Default.  In the event Landlord should become in default in
any payments due on any such mortgage described in the above Paragraph 20, or in
the payment of taxes or any other items which might become a lien upon the
Premises and which Tenant is not obligated to pay under the terms and provisions
of this lease, Tenant is authorized and empowered, after giving Landlord (and
the holder of any mortgage or deed of trust lien encumbering the Premises of
which it has received notice) five (5) days' prior written notice of such
default and if Landlord fails to cure such default, to pay any such items for
and on behalf of Landlord, and the amount of any item so paid by Tenant for or
on behalf of Landlord, together with any interest or penalty required to be paid
in connection therewith, shall be credited against the installments of rent next
payable by Tenant hereunder; provided, however, that Tenant shall not be
authorized and empowered to make any payment under the terms of this Paragraph
21, unless the items paid shall be superior to Tenant's interest hereunder.

     22.  Mechanic's Liens.  Tenant shall have no authority, express or implied,
to create or place any lien or encumbrance of any kind or nature whatsoever
upon, or in any manner to bind, the interest of Landlord in the Premises or to
charge the rentals payable hereunder for any claim in favor of any person
dealing with Tenant, including those who may furnish materials or perform labor
for any construction or repairs, and each such claim shall 


                                      11
<PAGE>

affect and each such lien shall attach, if at all, only to the leasehold 
interest granted to Tenant by this instrument.  Tenant covenants and agrees 
that it will pay or cause to be paid all sums legally due and payable by it 
on account of any labor performed or materials furnished in connection with 
any work performed on the Premises on which any lien is or can be validly and 
legally asserted against its leasehold interest in the Premises or the 
improvements thereof and that it will same and hold Landlord harmless from 
any and all loss, cost, or expense based on or arising out of asserted claims 
or liens against the leasehold estate or against the rights, titles, and 
interest of Landlord in the Premises or under the terms of this lease.  
Further, Tenant agrees that it will immediately remove and have released any 
mechanics' materialmen's or similar lien which may become attached to the 
Premises or any interest therein during the term hereof.

     23.  Notices.  Each provision of this instrument or of any applicable
governmental laws, ordinances, regulations, and other requirements with
reference to the sending, mailing, or delivery of any notice or the making of
any payment by Landlord to Tenant or with reference to the sending, mailing, or
delivery of any notice or the making of any payment by Tenant to Landlord shall
be deemed to be complied with when and if the following steps are taken.

     A.   All rent and other payments required to be made by Tenant to Landlord
hereunder shall be payable to Landlord at the address hereinbelow set forth or
at such other address as Landlord may specify from time to time by written
notice delivered in accordance herewith.

     B.   All payments required to be made by Landlord to Tenant hereunder shall
be payable to Tenant at the address hereinbelow set forth, or at such other
address within the continental United States as Tenant may specify from time to
time by written notice delivered in accordance herewith.

     C.   Any notice or document required or permitted to be delivered hereunder
(other than a payment, which shall be deemed received only when actually
received) shall be deemed to be delivered whether actually received or not when
deposited in the United States Mail, postage prepaid, certified or registered
mail, addressed to the appropriate party hereto at the address set out opposite
its name below, or at such other address as it has theretofore specified by
written notice delivered in accordance herewith:

LANDLORD:                               TENANT:

Industrial Properties Corporation       SI Diamond Technology, Inc.
400 East Carpenter Freeway              3006 Longhorn Blvd., Suite 107
Irving, TX  75062-3955                  Austin, TX  78758

If and when included within the term "Landlord," as used in this instrument,
there are more than one person, firm, or corporation, all shall jointly arrange
among themselves for their joint execution of a notice specifying an individual
at a specific address for the receipt of notices and payments to Landlord; if
and when included within the term "Tenant," as used in this instrument, there
are more than one person, firm, or corporation, all shall jointly arrange among
themselves for their joint execution of a notice specifying an individual at a
specific address within the continental United States for the receipt of notices
and payments to Tenant.  All parties included within the terms "Landlord" and
"Tenant," respectively, shall be bound by notices given in accordance with the
provisions of this paragraph to the same effect as if each had received such
notice.

     24.  Miscellaneous.

     A.   Words of any gender used in this lease shall be held and construed to
include any other gender, and words in the singular number shall be held to
include the plural and vice versa, unless the context otherwise requires.


                                      12
<PAGE>

     B.   The terms, provisions, and covenants and conditions contained in this
lease shall apply to, inure to the benefit of, and be binding upon, the parties
hereto and upon their respective heirs, legal representatives, successors, and
permitted assigns, except as otherwise herein expressly provided.

     C.   The captions are inserted in this lease for convenience only and in no
way define, limit, or describe the scope or intent of this lease, or any
provision hereof, nor in any way affect the interpretation of this lease.

     D.   Tenant agrees, within ten (10) days after request of Landlord, to
deliver to Landlord, or Landlord's designee, an estoppel certificate stating
that this lease is in full force and effect, the date to which rent has been
paid, the unexpired term of this lease, and such other matters pertaining to
this lease as may be reasonably requested by Landlord.

     E.   This lease may not be altered, changed, or amended except by an
instrument in writing executed by Landlord and Tenant.

     F.   This instrument [including all Exhibits and Riders (signed or
initialled by Landlord and Tenant) which are attached hereto] constitutes the
entire agreement between Landlord and Tenant.  No prior written or prior or
contemporaneous oral statements, promises, or representations shall be binding.

     G.   If any provision of this lease shall ever be held to be invalid or
unenforceable, such invalidity or unenforceability shall not affect any other
provision of the lease, but such other provisions shall continue in full force
and effect.

     H.   This lease shall be construed and enforced in accordance with the laws
and judicial decisions of the State of Texas.

     I.   Under no circumstances whatsoever shall Landlord ever be liable
hereunder for consequential damages or special damages; and all liability of
Landlord for damages for breach of any covenant, duty or obligation of Landlord
hereunder may be satisfied only out of the interest of Landlord in the Land and
Building existing at the time any such liability is finally adjudicated and all
rights to appeal have lapsed.  The term "Landlord" means only the owner of the
Land, and in the event of the transfer by such owner of its interests in the
Land, such owner shall thereupon be released and discharged from all covenants
and obligations of Landlord thereafter accruing, but such covenants and
obligations shall be binding upon each new owner for the duration of such
owner's ownership.

     J.   In the event of any act or omission by Landlord which would give
Tenant the right to damages from Landlord or the right to terminate this lease
by reason of a constructive or actual eviction from all or part of the Premises
or otherwise, Tenant shall not sue for such damages or exercise any such right
to terminate until (a) it shall have given written notice of such act or
omission to Landlord and to the holder(s) of the indebtedness or other
obligations secured by any first mortgage or first deed of trust affecting the
Premises.  If the name and address of such holder(s) shall have previously been
furnished to Tenant; and (b) a reasonable period of time for remedying such act
or omission shall have elapsed following the giving of such notice, not to
exceed thirty (30) days, during which time Landlord and such holder(s) or either
of them, their agents or employees, shall be entitled to enter upon the Premises
and do therein whatever may be necessary to remedy such act or omission.  See
Addendum 2.

     K.   Whenever a period of time is hereby prescribed for action to be taken
by Landlord or Tenant, Landlord or Tenant shall not be liable or responsible
for, and there shall be excluded from the computation for any such period of
time, any delays due to strikes, riots, acts of God, shortages of labor or
materials, war, governmental law regulations or restrictions or any other causes
of any kind whatsoever which are beyond the reasonable control of Landlord or
Tenant.  See Addendum 3.


                                      13

     L.   Landlord and Tenant agree and intend that this lease shall supersede
Section 92 of the Texas Property Code (and any successor statute) to the extent
of any conflict; without limiting the foregoing, none of the obligations or
duties imposed by such section shall be binding upon Landlord unless expressly
provided for in this lease.

     25.  Return of Premises.  At the end of the term covered by this lease, or
upon such earlier termination of this lease as provided herein, Tenant shall
surrender the Premises to Landlord in the same good order and condition as the
Premises were in prior to the beginning of the term hereof, reasonable wear and
tear excepted; provided, that in any case the Premises shall be surrendered to
Landlord reasonably clean and free of debris.  At such time Tenant shall deliver
to Landlord all keys to the Premises.  Any equipment, trade fixtures, or other
property of Tenant left in the Premises after the end of the lease shall be
conclusively deemed to have been abandoned by Tenant, and Landlord may thereupon
without notice to Tenant take possession of such property and, at Landlord's
option, either (i) declare same to be the property of Landlord, or (ii) at the
sole cost and expense of Tenant, dispose of such property in any manner and for
whatever consideration Landlord in its sole discretion shall deem most
advisable.  Tenant agrees that it will, promptly upon Landlord's request,
execute at Tenant's sole cost and expense, such bills of sale or other evidences
of title in such property as Landlord may request.

     26.  Special Provisions.  Additional Provisions, if any, set forth on
Exhibits and Riders attached hereto and made a part hereof for all purposes are
incorporated herein as if fully set forth in this Paragraph.  The attached
Exhibits and Riders are Exhibit "A" (Demising Plan), Exhibit "B" (Option Rider),
Exhibit "C" (Addendum to Lease Agreement).  Further, the following special
provisions are set forth below and made a part hereof for all purposes:

     27.  All rent and other payments required to be made by Tenant to Landlord

                             ATTACHED TO LEASE BETWEEN
                    INDUSTRIAL PROPERTIES CORPORATION, LANDLORD
                      AND SI DIAMOND TECHNOLOGY, INC., TENANT
                                 DATED JUNE 2, 1998


1.   Provided that Tenant is not in default under the terms hereof at either the
time of its exercise of the option herein provided or at the end of term
provided in the lease (or the end of the then current option period, if
applicable), Tenant shall have 1 consecutive options to exceed this lease for a
period of 3 years, each at the end of the primary term of the lease.  Each such
option must be exercised by Tenant giving Landlord written notice in accordance
with the notice provisions of the lease of its intention to exercise such option
not less than 180 nor more than 210 days prior to the end of the primary term,
or the previous option period, as the case may be.

2.   For each option period exercised by Tenant in accordance herewith the lease
shall be deemed extended and shall be continued in full force and effect with
respect to every applicable term and condition contained therein, except that
the rent payable with respect to the Premises for such option period shall be as
follows:

     Market Rental of Like Space -- Will reflect the current market rate,
     but under no circumstances will be less than the rental paid in the
     previous term.  If the Landlord and Tenant cannot agree upon the
     current market rate within thirty days following Tenant's exercise,
     and Tenant does not withdraw its exercise within fifteen days
     thereafter, then the Tenant and Landlord shall, within ten days, each
     select an appraiser who shall complete their appraisals within ten
     days after being selected.  Should the two appraisals produced by
     these appraisers not concur on the current market rate, then the two
     appraisers shall pick a third appraiser and the results of the third
     appraisal shall be the market rate (provided that such appraisal shall
     state a rate that is not more than the higher and no less than the
     lower rate determined by the two other appraisers).  If the appraised
     value is not determined prior to expiration of the Lease, Tenant shall
     continue to pay rent at the former rate until such determination is
     made, after which time the parties shall adjust the actual rent due
     for the prior period within thirty days.  The cost of the appraisal
     shall be borne by the party employing the appraiser, and the parties
     shall equally share the cost of the third appraiser, if any.

3.   In the event Tenant fails to exercise any option within the time and in the
manner provided herein, such option, and all subsequent options, shall be deemed
waived by Tenant and shall not be exercisable thereafter.

4.   The option provided herein is for the sole benefit of Tenant and may not be
exercised by any subtenant or assignee of Tenant, regardless of whether Landlord
has consented to or approved such subletting or assignment.

1.   Landlord and Tenant acknowledge and agree that Tenant shall have no
     responsibility whatsoever for or with respect to any Hazardous Substance or
     other environmental problem or liability with respect to the Premises
     caused by Landlord or Landlord's tenants, agents, employees, contractors,
     subcontractors, guests or invitees.

2.   provided, however, that if such remedy cannot be completed within thirty
     (30) days, Landlord shall not be in default so long as Landlord has
     commenced to remedy such act or omission, and diligently pursues the
     completion of such remedy.

3.   provided, however, that this provision shall not apply to any obligation or
     liability under this lease providing the payment of money when any such
     payment is due.
