                                        PART I

ITEM 1:  DESCRIPTION OF THE BUSINESS

BUSINESS DEVELOPMENT

    Photran Corporation ("Photran" or the "Company") was incorporated in 1991
under the laws of the State of Minnesota.  During the past three years, the
Company has not changed its form of organization or mode of conducting business,
except that the Company commenced commercial scale production of ITO coated
glass for the first time in July of 1995.  

GENERAL

    The Company develops, manufactures and markets high performance optical and
electrically conductive, thin film coated products.  The Company employs a
process based on a technology known as planar magnetron sputtering.  This
process is used to apply microscopically thin layers of metal, metal oxide,
nitride, boride, carbide and fluoride  to a wide variety of substrate materials.
These thin film coatings provide essential optical, electrical or durability
properties to a substrate material such as glass, metal, or plastic.

    The Company began commercial scale production on its first coating line in
July 1995.  The Company's first product is its PCO brand of indium tin oxide
("ITO") coated glass.  ITO coated  glass consists of a high quality sheet of
thin glass which the Company coats with a transparent, electrically conductive
ITO coating.  ITO coated glass is a principal component of flat panel displays. 
These displays are used in watches, calculators, lap top computers and consumer
electronics devices. 

TECHNOLOGY

    The Company's core manufacturing technology is based on a vacuum coating
process known as planar magnetron sputtering.  This process is used to apply
microscopic thicknesses of thin film coatings onto a variety of substrate
materials.  The coating process occurs in a specially designed vacuum chamber. 
The source material for the coating is normally a metal plate referred to as the
"target," which is mounted on a device called a "magnetron sputtering cathode." 
The cathode and target assembly becomes the negative terminal in an electrical
circuit.  A regulated power supply energizes the cathode and target, providing a
source of electrons.  A small volume of argon gas is introduced into the vacuum
chamber near the cathode.  Electrons emitted from the cathode collide with these
argon atoms causing the argon atoms to become positively charged or "ionized." 
The negative charge on the target provides a strong electrical attraction for
the argon gas ions causing them to strike the target with very high velocity. 
The kinetic energy of the argon gas ions, which is transferred to the target
surface, results in an atom of the target material being "sputtered" off the
surface.  The sputtered atom travels at a very high speed toward the substrate
material, which is


                                          2
<PAGE>


passing through the vacuum chamber.  The sputtered atom strikes the substrate
surface with sufficient force to form a strongly bonded coating.

ITO COATED GLASS PRODUCTS AND MARKETS

    To date, the Company's principal product has been its PCO brand TN grade
ITO coated glass.  The Company had orders for approximately 1,000,000 pieces of
ITO coated glass as of December 31, 1996.  The Company has also produced
enhanced reflection mirrors in limited quantities.

    PCO BRAND TN GRADE AND LCM BRAND STN GRADE ITO COATED GLASS.  The first
product the Company introduced was its twisted nematic (TN) grade ITO coated
glass that is the primary material used to construct many types of flat panel
displays.  The most common type of flat panel display is the TN grade liquid
crystal display ("LCD"), which is used in watches, calculators, electronic games
and most types of inexpensive consumer electronics devices.  These displays,
which incorporate TN grade ITO coated glass, are produced in very high volume by
an estimated 200 display manufacturing companies located in Japan and other
Asian countries.

    To further its market position and to attempt to secure higher margins, the
Company is developing a new ITO coated glass product for the high-resolution
super twisted nematic ("STN") segment of this market.  In 1997 the Company plans
to continue to focus on development of the STN grade market and to expand its
production capacity to allow for greater output of TN grade and the production
of STN grade ITO coated glass.

    Based on a report published by Stanford Resources, Inc., a market research
firm specializing in the electronic display industry, the worldwide market for
the ITO coated glass used to manufacture all types of LCDs is currently expected
to be approximately $268 million by the year 2000.  A report from the same
service indicates that by the year 2002 the market for flat panel displays, of
which ITO coated glass is a major component, is forecast to be more than $23
billion annually.  The projected compound annual growth rate for the LCD segment
of the flat panel display market is estimated to be approximately 21% for the
period from 1991 to 2000 by Semiconductor International, a trade publication. 
This rapid growth in the market for finished displays is expected to drive a
corresponding increase in demand for ITO coated glass.

    TOUCH SCREEN PANELS.   The Company also coats glass panels with ITO and
antimony tin oxide materials.  These coated glass panels are the principal
material component in all resistive and capacitive type touch screens. 
Resistive and capacitive type touch screens account for the majority of the
touch screen market.

A/R PRODUCTS AND MARKETS

    Anti-reflection ("A/R") coatings consist of microscopically thin layers of
metal and metal oxide materials that utilize the principle of light wave
interference to reduce the reflectivity of the


                                          3
<PAGE>


surface of a glass or plastic substrate. The Company is currently developing the
two A/R products described below.

    POLARCLEAR POLARIZING FILM.   The Company's PolarClear product will consist
of a sheet of plastic polarizing film, which is available from several sources
in the U.S. and Asia, to which the Company will apply an A/R coating.  The
Company does not currently purchase this material and does not have any
agreements with any suppliers of the material.

    Every LCD display utilizes a plastic polarizing film on the front of the
display.  According to a report by Stanford Resources the annual market for
polarizers is projected to be $420 million by the year 2000.

    ARTGLAS PICTURE FRAMING GLASS.  ArtGlas picture framing glass will consist
of a high quality sheet of clear glass that the Company will coat with A/R and
UV light blocking coatings.  UV light is present at very damaging levels in
sunlight and most fluorescent light.  It is the primary cause of irreversible
fading in paintings, prints and photographs.  

    According to the Professional Picture Framers Association, the annual
market for picture framing is approximately $4 billion.  Historically, picture-
framing glass has accounted for approximately 8% of the total framing cost.  The
Company estimates that between 10% and 12% of the glass currently used for
picture framing is a chemically etched "non glare" type of glass.  This product
reduces glare by creating a matte texture for the picture or artwork.  Although
it reduces glare, etched glass also reduces the image clarity and color
fidelity.  The Company is aware of two A/R coated picture framing glass products
produced by a chemical dip process but is not aware of any A/R picture framing
glass coating applied using sputtering technologies.

    The Company plans to sell ArtGlas for approximately the same price as
existing chemically dipped glass.  The Company believes that the price and
performance qualities of ArtGlas will provide the Company with competitive
advantages in the picture framing glass market.

    The Company's current production system cannot accommodate the large sheets
of glass required to produce ArtGlas.  The Company intends to install a coating
system that will be capable of coating 30" x 40" sheets of ArtGlas. 

ENHANCED REFLECTION MIRROR PRODUCTS AND MARKETS

    Enhanced reflection mirrors ("ERMs") are glass or plastic sheets coated
with highly reflective mirror coatings on the surface closest to the point of
use (front surface).  The Company commenced shipments of ERM products on a
limited basis in 1996.  To date, the Company's selling efforts with respect to
ERM products has been very limited.  The Company intends to focus additional
development and selling efforts on certain Asian customers during 1997.  It is
not possible to determine at this time whether sales of ERM products will
contribute materially to the Company's revenues in 1997.  


                                          4
<PAGE>


    PMAX ENHANCED REFLECTION MIRRORS.  The Company's PMAX enhanced reflection
mirrors consist of a polished glass sheet coated with an ultra-high reflection
mirror coating on the front surface.  Front surface mirrors are used in all
photocopiers, laser and bar code scanners, projection televisions, overhead
projectors and many other types of specialty mirror applications. 

SALES AND DISTRIBUTION

    The Company's sales and distribution activities are currently handled on a
direct basis and through selling agents.  The Company's sales efforts are
currently conducted largely by senior management.  Sales and distribution of
products under development will vary, depending on the product and the markets
to be pursued.

    ITO PRODUCTS

    ITO products are sold to manufacturers of flat panel displays.  These
displays are used in such products as watches, calculators and lap top
computers.  The Company sells its ITO coated glass and touch screen products
directly and through independent sales agents in the U.S. and Asia. This method
of distribution has provided a low cost, effective method of serving these
markets.

    The Company has informal sales arrangements with several U.S. and Asian
sales agents and is in the process of formalizing these arrangements.  These
sales agents are paid a sales commission that is standard for the industry.

    A/R PRODUCTS

    POLARCLEAR POLARIZING FILM.  PolarClear A/R and UV light blocking
polarizing films will be distributed through the Company's existing ITO coated
glass selling agents.  This product is used by the same customers who purchase
the Company's ITO coated glass products.

    ARTGLAS PICTURE FRAMING GLASS.  ArtGlas will be sold on a wholesale basis
to a limited number of established distributors of picture framing glass in the
U.S. and Europe.

    ENHANCED REFLECTION MIRROR PRODUCTS

    PMAX ENHANCED REFLECTION MIRRORS.  To reach the markets for ERMs, the
Company will utilize sales agents to call on manufacturers of photocopiers,
laser and bar code scanners, overhead projectors and projection televisions.

COMPETITION

    The Company has not yet shipped significant quantities of products in any
of the markets in which it intends to compete.  It has not, therefore,
established a significant market presence in any of these markets.  


                                          5
<PAGE>


    ITO PRODUCTS

    TN GRADE AND STN GRADE ITO COATED GLASS.  Approximately half of the world's
production capacity for TN grade ITO coated glass is located in Japan.  Japanese
LCD manufacturers utilize most of the ITO coated glass production capacity in
Japan.  The principal suppliers of ITO coated glass for the LCD industry outside
of Japan are Applied Films Corporation of Boulder, Colorado; Samsung Corning of
Seoul, South Korea and Merck Balzers of Liechtenstein.  These ITO suppliers have
substantial financial, technical, manufacturing and marketing resources, are
well established and will provide formidable competition to the Company for the
foreseeable future.  The Japanese ITO coating manufacturers are not active in
supplying markets outside of Japan.  However, to the extent the Company attempts
to develop business in Japan they will provide direct competition.

    Because of the strong competition in the TN grade ITO coated glass market,
the Company is planning to focus on the higher quality, higher margin STN grade
segment of the ITO coated glass market.  The Company believes that only three
Japanese ITO producers and Samsung Corning are able to supply significant
quantities of STN grade ITO coated glass.  The Company estimates that until
recently, approximately 90% of the demand for STN grade ITO coated glass was in
Japan.  However, beginning in the fourth quarter of 1995, several new STN grade
LCD production lines have commenced production in Taiwan, Singapore, Korea and
Hong Kong.  The Company believes that the non-Japanese markets for STN grade ITO
coated glass will be easier to penetrate than the Japanese market.  The Company,
therefore, intends to target the non-Japanese markets for STN grade LCD
manufacturing and has made a strategic decision to refrain from entering the
Japanese market because formidable competition and captive markets would make
such penetration difficult and costly.

    TOUCH SCREEN PANELS.  The only existing supplier of ITO and antimony tin
oxide coated panels for the touch screen market of which the Company is aware is
the Display Products Division of Donnelly Corporation in Holland, Michigan. 
Donnelly has fully integrated production facilities for glass bending and thin
film coating.  The Company's touch screen product is manufactured using a
different coating technology which the Company believes is more efficient than
the process used by its competitors.  The Company intends, therefore, to compete
in this market on the basis of price.

    A/R PRODUCTS

    POLARCLEAR POLARIZING FILTERS.  The market for A/R coated polarizing
plastic sheets has developed rapidly in the last two years.  Currently Optical
Coating Laboratory, Inc. (OCLI) of Santa Rosa, California and Nitto Denko of
Japan account for the majority of the market for A/R coated polarizing material.
There are five other principal suppliers of polarizing material worldwide. 
Three are in Japan and two are in the U.S.  Each of these companies has
substantial manufacturing, technical, marketing and financial resources.  The
Company believes the processes it has under development will enable it to
compete on the basis of both cost and quality. 


                                          6
<PAGE>


    ARTGLASS PICTURE FRAMING GLASS.  There are two companies of which the
Company is aware that currently supply anti-reflection picture framing glass. 
Denton Vacuum, Inc. of Cherry Hill, New Jersey, and Schott Glas Werks of Mainz,
Germany, sell anti-reflection picture glass for the framing market that is
manufactured by a chemical dip process.  The Company believes its ArtGlass
product will have more effective optical and A/R properties than products
offered by competitors and believes that these properties will provide a
competitive advantage in this market.  The Company plans to sell ArtGlass for
approximately the same price as existing chemically dipped glass.

    ERM PRODUCTS

    PMAX ENHANCED REFLECTION MIRRORS.  The market for enhanced reflection
mirrors is currently being served by OCLI, Viratec Thin Films, Inc. (Viratec) of
Faribault, Minnesota and Opton, Inc. of Norfolk, Virginia.  These three
companies are believed to supply more than 90% of the worldwide demand for ERMs.
All three companies have large manufacturing facilities in the U.S., Europe and
Asia for cutting and edge grinding of these products to meet end user
specifications.  The Company intends to compete in this market on the basis of
price.

RAW MATERIALS

    The principal raw materials used in the Company's manufacturing processes
are glass substrates, which are coated with thin films, and the targets, which
are the source material for the thin film coatings. The glass used for ITO
coated glass is a special grade of thin soda lime glass.  This material is
available from five suppliers worldwide.  The Company currently purchases its
glass substrate from Glaverbel, S.A. of Belgium, although it does not have a
long term supply agreement with this supplier.  Other suppliers are located in
the U.K. and Japan.  The Company believes that it can obtain comparable quality
material from other suppliers should its current source be disrupted.  Raw
materials for products to be introduced in 1997 and the target materials are
widely available from a variety of sources.

CUSTOMERS

    During 1995, sales of ITO coated glass to the Company's two largest
customers accounted for 57% and 28% of total revenue, respectively.  Sales to
the largest customer accounted for 87% of 1996 sales.  The Company's largest
customer is located in Taiwan and is the largest LCD manufacturer outside of
Japan.  The Company does not have any long-term contractual commitments from its
customers.  The Company sold its PCO brand of ITO coated glass to a limited
number of customers in 1995 and 1996, primarily due to production capacity
limitations.  The Company expects to increase its productive capacity during
1997, and anticipates that it will be able to expand its ITO product customer
base when this increased capacity is available.

    The Company plans to further expand its customer base in the near term
through new product offerings.  Based on current sales to its largest customer,
however, the Company expects that customer to continue to account for at least
50% of its sales revenue in 1997.


                                          7
<PAGE>


    Customers for the Company's ITO coated glass products are predominantly
located in Asia.  The Company anticipates that the initial customers for its A/R
and ERM products will be located predominantly in the U.S.

INTELLECTUAL PROPERTY

    The Company's policy is to attempt to protect its technology by, among
other things, filing patent applications for technology that it considers
important to the development of its business.  The Company has seven issued U.S.
patents, four U.S. patent applications which have been filed and 16 U.S. patent
applications which have been prepared and are in the process of being finalized
for filing.  The validity and breadth of claims covered in the Company's patents
and patent applications involve complex legal and factual questions and,
therefore, may be highly uncertain.  No assurance can be given that the
Company's pending applications will result in patents being issued or if issued
that such patents or the Company's existing patents will provide a competitive
advantage, or that competitors of the Company will not design around any patents
issued to the Company.  Other than the prior art review done in connection with
the Company's patent applications, the Company has not undertaken any
independent investigation regarding potential infringement of its current or
proposed products on the property rights of others.

GOVERNMENT REGULATION; ENVIRONMENTAL LAWS

    The Company's business is not subject to any material governmental
regulations, nor are any governmental approvals required for the operations of
the Company as currently conducted or anticipated to be conducted in the
foreseeable future.  Costs and effects of environmental compliance are also not
material to the Company's business.

RESEARCH AND DEVELOPMENT

    The Company spent $353,636 and $455,847 on research and development
activities in 1995 and 1996, respectively.  None of these expenditures are borne
directly by customers.

EMPLOYEES

    As of December 31, 1996, the Company had 107 full-time employees and 2
part-time employees.  Of these full-time employees, 15 were in research and
development and engineering, 40 were in manufacturing and production, 33 were in
machining, machine assembly and facilities maintenance, one was in sales, and 18
were in management or administrative positions.  In March of 1997 management
eliminated 21 full-time positions.  These staff reductions primarily affected
the engineering, research and machining departments.  None of the Company's
employees are covered by a collective bargaining agreement, and management
considers its relations with its employees to be good.

ITEM 2 - DESCRIPTION OF PROPERTY

FACILITIES

    The Company leases its main office and manufacturing facility located at
21875 Grenada Avenue, Lakeville, Minnesota 55044.  This 23,000 square foot
facility consists of 16,000 square feet of manufacturing space (including
approximately 10,000 square feet of high quality environmentally controlled
clean room area).  The remaining 7,000 square feet is used for administrative,
engineering, R & D and sales offices.  The Company also leases a nearby 47,000
square foot building located at 21725 Hanover Avenue, Lakeville, Minnesota
55044.  The Company intends to use this facility for its machine shop, shipping
and receiving, and another manufacturing line.  The Company has options to
purchase both of these buildings.  The Company believes these facilities are in
good condition and are adequate for the foreseeable future.  The Company carries
insurance covering the full replacement value of these properties.  For
discussion concerning the lease obligations, see Note 6 to Financial Statements.

EQUIPMENT

    The Company currently operates a single in-line coating machine which it
has designated "P-1."  The P-1 line is housed in a high quality environmentally
controlled clean room.  It is being used primarily to produce ITO coated glass.

    During the fourth quarter of 1996, the Company was informed by its Chinese
joint venture partner of the partner's desire to dissolve the joint venture. The
Company had been constructing a coating line for sale to the joint venture. The
Company will now keep this coating line, designated the "P-1000," and is
currently modifying it to suit the Company's manufacturing needs.  This
equipment is owned by a lease financing company subject to the Company's
obligation to purchase the equipment at the end of the lease term.  See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - China Joint Venture."

    The Company owns the majority of its manufacturing equipment (other than
the P-1000) as well as equipment used in its research and development
activities.  Some of the Company's machine shop and office equipment is subject
to operating and capital leases none of which are material to the Company's
business.  All of the Company's personal property, whether owned or leased, is
in good condition and adequate for the foreseeable future.

ITEM 3 - LEGAL PROCEEDINGS

    The Company was not a party to any legal proceedings during 1996.  On April
10, 1997, the Securities and Exchange Commission notified the Company that the
Commission had commenced a formal investigation with respect to certain
financial and accounting irregularities that had been identified by the Company
and its independent auditors.  The investigation is in the


                                          9
<PAGE>


preliminary stages and it is not possible to determine at this time what impact,
if any, the investigation will have on the Company's financial condition or
results of operations. 

     During the quarter ended December 31, 1996, the Company was informed by 
its Chinese joint venture partner of the partner's intention to dissolve the 
joint venture agreement and cancel the related equipment purchase contract.  
In April 1997, the Company received notice that arbitration proceedings had 
been commenced against it by its joint venture partner, claiming 
approximately $4.4 million plus legal fees and costs.  This process is still 
in a very early stage, and it is too soon to determine whether the Company 
will be liable for any additional amounts beyond the return of amounts which 
are recorded as customer deposits (see Note 2).  It is possible that 
additional amounts due upon final dissolution of this agreement could be 
material to the financial position and operating results of the Company.

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

    No matter was submitted by the Company to a vote of security holders during
the quarter ended December 31, 1996.

RESTATEMENTS OF INTERIM FINANCIAL RESULTS

    The Company has determined that it was necessary to restate previously 
reported interim financial results for the first, second and third quarters 
of 1996.   A tabular comparison of the statement of operations and balance 
sheet for the quarter ended March 31, 1996 as previously reported and as 
restated has been filed with the Commission on Form 8-K.  Similar tabular 
comparisons of the statements of operations and balance sheets for the 
quarters ended June 30, 1996 and September 30, 1996 have been filed with the 
Commission as amendments to the Company's quarterly reports on Form 10-QSB 
for such quarters.  Presented below is a description of the items restated by 
quarter.

QUARTER ENDED MARCH 31, 1996

    Revenue for the first quarter of 1996 has been reduced by $460,491 
related to recorded sales transactions that did not meet the Company's 
criteria for revenue recognition.  In addition, errors in the valuation of 
raw materials inventory, depreciation and in the computation of capitalized 
interest increased cost of sales and interest expense by $66,000 and $84,000 
respectively.

QUARTER ENDED JUNE 30, 1996

    Revenue for the second quarter of 1996 has been reduced by $867,453 due 
primarily to the reversal of equipment sales revenue of $910,000 resulting 
from recognition criteria not being met.  The Company has also corrected an 
error in the valuation of raw materials inventory.  This correction decreased 
gross profit by $37,000. Accordingly, costs previously reported as cost of 
sales have now been classified as equipment held for sale on the balance 
sheet.  See "Results of Operations -Revenue."

QUARTER ENDED SEPTEMBER 30, 1996

    Revenue for the third quarter of 1996 has been reduced by $1,312,970. 
Previously reported net sales transactions of $173,000 that did not meet the 
Company's criteria for revenue recognition have been reversed.  In addition, 
equipment sales revenue of $1,140,000 has been reversed as a result of the 
change to the completed contract method of revenue recognition on an 
equipment contract discussed above.  Costs previously reported as cost of 
sales have now been reclassified as equipment held for sale.  See "Results of 
Operations - Revenue."

RESULTS OF OPERATIONS

REVENUES

    For the year ended December 31, 1996 net sales decreased 17% to 
$2,886,540 from $3,362,818 in 1995.  Revenues consisted primarily of gross 
sales of TN grade ITO coated glass. The decrease in revenue for the year 
ended December 31, 1996 compared to 1995 is due primarily to a combination of 
a general market price reduction for TN grade ITO coated glass and a change 
by the Company's principal customer to a smaller sheet size.  These changes 
had the combined effect of reducing the unit price of the Company's TN grade 
ITO coated glass by approximately 50% from the beginning of the year to the 
end of the year.  This decrease in per unit revenue was partially offset by 
an increase in the number of units produced of approximately 28%. 

    The Company expects the market price for TN grade ITO coated glass will
begin to recover in the second half of 1997.  The Company is also pursuing sales
of larger size substrates that will provide increased revenue per unit for
substantially the same coating cost per unit.  The Company also expects to
expand its productive capacity in 1997 with the addition of one or more thin
film coating lines.   Based on recent discussions with its Asian selling agents
and current customers, management anticipates significant growth in revenue from
the sale of ITO coated glass in 1997 following the addition of productive
capacity.

    During 1996 the Company dedicated a significant portion of its available
production time on its P-1 line to the development of full scale production
processes for enhanced reflection mirrors


                                          13
<PAGE>


and its LCM brand ITO coated glass.  Management believes because of the
fluctuations in the market for TN grade ITO it is necessary to accelerate the
shift in product mix from TN grade ITO to these products.  The Company is
providing samples to prospective customers and is working with its independent
sales representatives to develop customers for these products.

    During 1996 most of the Company's engineering capabilities were dedicated 
to the design and construction of two thin film coating lines, one of which 
was held for sale at December 31, 1996.   As a result, the Company did not 
realize increases in productive capacity and capabilities in 1996.

    In the summer of 1996 the Company entered into an agreement to sell certain
ITO coating equipment to its largest customer for a total contract price of
$2,916,500.  The Company has received a down payment of $500,000.  Revenue of 
$2,050,000 from the equipment contract was recognized on the percentage-of-
completion method through the third quarter of 1996.  Delivery of the equipment
was originally scheduled for the fourth quarter of 1996.  Delivery was delayed
and the customer has requested the Company to install and operate the equipment
in the Company's facilities during 1997.   The Company is in the process of
negotiating contract amendments to extend the delivery date.  The amendments had
not been finalized as of the date of this report and, therefore, the Company has
determined that it is appropriate to change to the completed contract method of
accounting for this transaction in the fourth quarter of 1996.  Previously
reported revenues and cost of sales related to this transaction, which were
recorded in the second and third quarters of 1996, have been reversed
and the associated costs have been classified as equipment held for sale in the
December 31, 1996 balance sheet.   

    The Company's largest customer accounted for 87% and 57% of the Company's
revenue during 1996 and 1995, respectively.  This customer is the prospective
purchaser of the ITO coating equipment discussed above.  If the sale is
consummated, to the extent that this equipment satisfies a significant portion
of the customer's need for ITO coated glass, the Company will need to find
additional customers to replace this source of revenue.  The Company expects,
however, to continue supplying this customer with ITO coated glass in future
periods.  Based on recent discussions with this customer, management currently
expects the customer's purchases of ITO coated glass in future periods to be
comparable to historical levels, although no long-term purchase commitments
exist. During 1995, a second customer accounted for 28% of total revenue.

GROSS PROFIT (LOSS)

     Gross loss was $723,748 in 1996, compared to gross profit of $1,314,296 
in 1995.  The loss was due in part to the shift to smaller sheet size and 
market and unit price decreases discussed above.  Cost of sales consists of 
substrate costs, target material costs, labor and overhead related to the 
Company's manufacturing operations.  Cost of sales also includes the costs 
associated with the enhancements of commercial scale production processes for 
the manufacture of the Company's LCM brand ITO coated glass and improvements 
in the process for enhanced reflection mirrors.  The production of these 
products requires ultra clean substrates and must be performed in a clean 
room environment to achieve acceptable production yields.  Management made 
the decision


                                          14
<PAGE>


to commence production of these products on its existing production line prior
to the installation of the clean room and material handling and cleaning
upgrades.  As a result, production yields were significantly reduced and scrap
cost increased.   Management believes that equipment and facility improvements
planned for 1997 will resolve these problems.

    In addition, during the fourth quarter of 1996 the Company determined that
certain glass inventory that the Company had successfully coated and sold
earlier in 1996 had become stained by the packaging materials.  The multiple
washings which this glass required and the poor quality of output and high scrap
rates have made it economically unfeasible to attempt to coat this glass. 
Management, therefore, has reduced the carrying value of this inventory by
approximately $400,000 and charged that amount to cost of sales in the fourth
quarter. 

PROCESS AND PRODUCT DEVELOPMENT

    Process and product development expenses increased to $455,847 in 1996 from
$353,636 in 1995.  These expenses consist of personnel costs, consulting,
testing, supplies and depreciation expenses.  The increase in 1996 was due
primarily to increased personnel and consulting fees incurred for the purpose of
expanding the Company's product line.  

GENERAL AND ADMINISTRATIVE EXPENSES  

    General and administrative expenses increased to $1,003,365 in 1996 from 
$462,686 in 1995.  These expenses consist primarily of compensation expenses 
for administration, finance, and general management personnel, as well as 
office supplies, depreciation, bad debt and professional fees. The increase 
in 1996 is partially a result of increased staffing.  Bad debt expense 
increased by approximately $80,000 due to the bankruptcy of one customer in 
late 1996.  In addition, the Company incurred significant professional fees 
in connection with a special investigation of certain transactions which were 
recorded in 1996 which was initiated by the Board of Directors and led to a 
restatement of previously reported interim financial results for the first, 
second, and third quarters of 1996. Additional professional fees will be 
incurred in connection with this investigation in 1997, but it is not 
currently possible to determine whether such fees will be material to the 
Company's 1997 results of operations.

SELLING EXPENSES

    Selling expenses increased to $ 459,281 in 1996 from $161,531 in 1995. 
These expenses consist principally of compensation costs for sales personnel,
commissions, travel expenses, trade show expenses, and freight out costs.  The
addition of sales and customer support staff and increases in trade show, travel
and freight costs are the primary reasons for the increase in selling expenses
for the year ended December 31, 1996. 


                                          15

OTHER NONRECURRING CHARGES

    In the fourth quarter of 1996 the Company's Chinese joint venture partner
notified the Company of its intention the cancel a joint venture agreement with
the Company and a related equipment purchase contract with the Company.  In
connection with the cancellation of the equipment purchase contract, the Company
determined that certain equipment which was to have been sold to the joint
venture and equipment that was under development for the Company's use was no
longer economically feasible or did not fit the Company's current manufacturing
needs. This equipment, which the Company determined had no foreseeable future
value, was written off, resulting in a charge of $1,800,000.

    In the fourth quarter of 1996, the Company discontinued its development of
commercial scale production equipment for its ZeroRay-TM- glare and radiation
control filters due to technical difficulties encountered with the large scale
production of the optical gel adhesive necessary for attaching the filters to
computer and television screens.  Management believes that the resolution of
these issues would have required significant additional resources and would have
raised the cost of the filters to a point where the product could not be
competitive with other similar products. In connection with this decision,
management determined that production equipment that had been purchased to
manufacture the ZeroRay product had been impaired.  The Company determined that
this equipment, which had a historical cost of approximately $378,000, had no
foreseeable future value and was, therefore, written off.

     In addition, the Company determined that as a result of refocusing of its
operations, a piece of manufacturing equipment had little future value to the 
Company at December 31, 1996.  The machine has been written down to its fair 
value, resulting in an impairment charge of approximately $272,000 in the 
fourth quarter of 1996.

NET INTEREST EXPENSE

    For the year ended December 31, 1996 the Company had interest expense net
of interest income of $78,367 compared to interest expense of $286,430 in 1995.
The change was due to the earnings from the investment of the proceeds from the
Company's initial public offering.  In addition, the Company retired
substantially all of its outstanding debt in June of 1996 after its initial
public offering. 

EXTRAORDINARY ITEM

     Upon repayment of the Company's Bridge Notes in June 1996, the remaining 
unamortized balance of $71,990 in deferred financing fees was written off.  
The loss on extinguishment has been classified as an extraordinary item in 
the Statement of Operations for the year ended December 31, 1996.

NET INCOME (LOSS)

    The net loss of $5,281,907 for the year ended December 31, 1996 compared to
net income of $50,013 for 1995 was primarily due to the non-recurring charges
and inventory valuation adjustments discussed above.  In addition, the decrease
in the unit revenues discussed above and the product and process enhancement
costs included in cost of sales contributed to the loss.

NET OPERATING LOSS CARRYFORWARDS

     In accordance with Section 382 of the Internal Revenue Code of 1986, as 
amended (the "Code"), a change in ownership of greater than 50% of the 
Company within a three year period results in an annual limitation on the 
Company's ability to utilize its net operating loss ("NOL") carryforwards 
which accrued during the tax periods prior to the change in ownership.  As of 
December 31, 1996, the Company had an NOL carryforward of approximately $6.5 
million which expires in 2006 through 2010.  Due to certain ownership changes 
which occurred during the year ended December 31, 1993, the NOL carryforwards 
of $700,000 incurred through February 1993, which can be utilized by the 
Company on an annual basis, are limited to approximately $50,000.  The annual 
limitation may be increased for any built-in gains recognized within five 
years of the date of the ownership change.  Utilization of the approximately 
$5.8 million of NOL carryforwards incurred after February 1993 is not limited 
under Section 382 of the Code.  However, the Company's ability to use its NOL 
carryforwards may be further limited by subsequent issuances of common stock.

CHINA JOINT VENTURE

    In 1994 the Company entered into a joint venture agreement with the
Shenzhen WABO Group Company Limited ("WABO"), of Shenzhen, China.  The agreement
is governed by the laws of the People's Republic of China.  The joint venture
company, known as the Shenzhen Fortune


                                          16
<PAGE>


Conductive Glass Company, Ltd. ("Fortune"), was created to produce TN grade ITO
coated glass for the Asian market.

    The Company had agreed to sell to Fortune an ITO glass coating system and
technology limited to the production of TN grade ITO coated glass for the gross
purchase price of $10,145,000.  The Company had also agreed to provide a royalty
free license to Fortune for the use of certain of the Company's proprietary
technology for the production of TN grade ITO coated glass.  The Company was
obligated to provide 40% of the $11,645,000 total capitalization of the joint
venture.  This 40% contribution, totaling $4,658,000, was deducted from the
gross purchase price of the coating system.  This was to result in the Company
receiving a net purchase price of $5,487,000 for the equipment sold to the joint
venture.  The Company was not relying on any material earnings or distributions
from Fortune and, therefore, recorded the costs incurred as equipment held for 
sale.  The Company was accounting for this sale on the completed contract 
method.

    The equipment was originally scheduled to be shipped by November 6, 1995.
The project was delayed for several months due to a delay by WABO in delivering
a required letter of credit and the Company's resulting inability to obtain
working capital financing on a timely basis.  The project schedule was
subsequently extended by mutual agreement between the parties.  WABO failed to
deliver a required extension of the letter of credit on a timely basis, which
further delayed the project and prevented the Company from shipping the
equipment by April 15, 1996.  The Company was subject to certain contractual
penalties for failure to ship by April 15, including the refund of Fortune's
advance of approximately $1.5 million, which amount had been recorded as a
current liability of the Company.  WABO orally agreed to waive these penalties
provided the equipment was shipped no later than June 30, 1996.  The equipment
did not ship by June 30, 1996.

    During the quarter ended December 31, 1996, the Company attempted to
resolve the issues regarding payment of penalties as well as payment for various
technical modifications. The Company had negotiated with representatives of WABO
and had drafted an amendment to the agreement to resolve these issues.  The
Company was subsequently informed by WABO of their intention to dissolve the
joint venture agreement.

    The Company will keep the glass coating system, and plans to modify and 
install the equipment for its own use. The equipment has been reclassified to 
property, plant, and equipment at December 31, 1995. The Company has recorded 
an additional liability of approximately $200,000 related to glass that was 
provided by WABO for use in testing the system. In April 1997, the Company 
received notice that arbitration proceedings have been commenced against it 
by WABO, claiming damages of or reimbursement of approximately $4.4 million 
plus legal fees. This process is still in a very early stage, and it is too 
soon to determine whether the Company will be liable for any additional 
amounts. It is possible, however, that additional amounts due upon final 
dissolution of the joint venture could have a material adverse effect on the 
financial position and operating results of the Company.

LIQUIDITY AND CAPITAL RESOURCES

    The Company has incurred accumulated losses since its inception of 
$8,718,768 and incurred negative cash flows from operating activities of 
$1,478,877 for the year ended December 31, 1996. The Company had cash outlays 
for property and equipment additions of $8,896,744 for the year ended 
December 31, 1996.

    The Company's continuation as a going concern is dependent on its ability 
to meet its obligations as they become due. The accompanying financial 
statements do not include any adjustments relating to the recoverability and 
classification of recorded asset amounts or the amounts and classification of 
liabilities that might be necessary should the Company be unable to continue 
as a going concern. Management's plans regarding operating losses and its 
plans concerning the above matters are presented in the Outlook section below.

    As of December 31, 1996, the Company's principal sources of liquidity 
included cash and cash equivalents of $2,038,955 and net accounts receivable 
of $606,500.  As discussed in the Outlook section below, management believes 
that its existing sources of liquidity and anticipated funds from operations, 
including collections on equipment sales, combined with the net proceeds from 
a first quarter 1997 sale-leaseback accounted for as a financing transaction 
of $2,250,000, will satisfy the Company's projected working capital and 
capital expenditure requirements for 1997. Management is, however, also 
investigating the possibility of obtaining working capital financing, 
although there can be no assurance that such financing will be available or 
be available on terms acceptable to the Company.

    The net cash used in operating activities for 1996 was $1,478,877 due
principally to the net loss for the year of $5,281,907 which was partially
offset by non-cash charges for depreciation and asset impairment losses.
Expenditures for equipment held for sale were $937,706, offset by the receipt of
a $500,000 downpayment.  

     In 1996, the Company entered into an agreement to sell ITO coating 
equipment to its largest customer for a total contract price of $2,916,500.  
The Company received a down payment of $500,000 which is recorded as a 
customer advance at December 31, 1996.  Delivery of the equipment was 
originally scheduled for the fourth quarter of 1996.  This delivery has been 
delayed, and the customer has requested the Company to install and operate 
the equipment in the Company's facilities during 1997.  The Company is in the 
process of negotiating contract amendments to extend the delivery date and 
clarify payment terms in light of the changed nature of the agreement.  Costs 
incurred to date have been classified as equipment held for sale as of 
December 31, 1996.

    Cash used in investing activities was $8,896,744 during 1996 compared to
$2,474,835 in 1995.  In both periods this cash was used for the purchase of
equipment and leasehold improvements.  In 1996 expenditures related to the
equipment intended for sale to the Company's China joint venture have been
categorized as additions to property and equipment due to the cancellation of
the equipment purchase agreement and the Company's decision to use this
equipment as a second manufacturing line.  Internal costs, consisting primarily
of direct labor and supplies used in the construction of equipment, of
approximately $2,470,000 and $1,010,000 were capitalized or charged to
construction in process during 1996 and 1995 respectively.

    Cash flows from financing activities during the year ended December 31,
1996 consisted primarily of approximately $18,500,000 in proceeds from the
Company's initial public stock offering in May 1996.   Following the
offering, the Company repaid $4,000,000 of Bridge Notes together with
approximately $287,500 in accrued interest and a loan from a director of
$1,166,668.  The Company also repaid a $2,000,000 EXIM secured bank line of
credit from the proceeds of the offering to reduce interest payments and to
avoid payment of EXIM renewal fees.         

OUTLOOK

    In March 1997, David E. Stevenson, the Company's president and founder,
resigned as an officer and director.  The Company has assembled an executive
committee comprised of a Vice President for Finance and Administration, a Vice
President for Manufacturing and a Vice President for Technology.  The Company
has also hired a Corporate Controller.  The Company's short-term focus is on
increasing revenues, decreasing expenses, increasing production capacity and
improving manufacturing capabilities.  The executive committee, together with
the Board of Directors, is currently developing a strategic plan to return the
Company to profitability.  The new management team, together with the Company's
Board of Directors, has taken several


                                          18

steps to refocus the Company's efforts  during the last 45 days.  The Company 
has terminated several engineering projects that did not directly relate to 
the installation of additional coating equipment at the Company's facilities. 
 In an effort to focus all of the Company's personnel on manufacturing 
activities and the development and refinement of core deposition 
technologies, in March of 1997 the Company also laid off 21 employees, and 
reassigned several others.  In addition, the restructuring of manufacturing 
shifts and process modifications made to the P-1 line have resulted in a 
significant increase in production output.  Moreover, the Company has engaged 
in direct discussions with its major customers, selling agents, and 
suppliers, and none of these customers, selling agents or suppliers have 
indicated an intention to terminate their relationship with the Company.

    Management expects that sales of TN grade ITO coated glass will be the
predominant source of revenue during 1997.  Although the Company is continuing
to work on the development of additional products for introduction in 1998,
management expects that TN grade ITO coated glass sales will continue to
generate the majority of the Company's revenues in 1998 as well. 

     Based on the actions described above, the Company believes that its 
existing sources of liquidity and anticipated funds generated by operations 
will satisfy the Company's working capital and capital expenditure 
requirements for 1997.  It is possible, however, that the Company may have to 
obtain additional capital through the issuance of equity or debt securities.  
There can be no assurance that such additional capital will be available or 
be available on terms acceptable to the Company.

    New product introductions will depend on the success of the  Company's 
development efforts and on the results of management's analysis of market 
opportunities and capital expenditure requirements. The Company's ability to 
increase revenues is highly dependent on its ability to complete the 
installation of additional coating equipment.  The capital expenditures 
related to such installation are expected to be available from internally 
generated funds, including proceeds from the sale of ITO coating equipment to 
the Company's principal customer (see Results of Operations - Revenues).  If 
the Company is unable to finalize the contract amendments currently under 
discussion with that customer, it intends to keep the equipment for its own 
use; the loss of equipment sale revenue associated with this transaction, 
together with a refund of the customer's down payment of $500,000, however, 
would force the Company to slow the process of installing additional 
equipment and possibly force it to seek external capital to fund necessary 
capital expenditures.  Barring any unforeseen adverse external developments, 
however, management believes that the Company's new plan, which will build on 
the Company's asset base and technology position, will provide for the growth 
in revenue and earnings necessary for the long term financial health of the 
Company.

OTHER FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

    The Company's future operating results may fluctuate significantly due to
factors such as the timing of new product announcements and introductions by the
Company, its major customer and its competitors, market acceptance of new or
enhanced versions of the Company's products, changes in the product or customer
mix, changes in the level of operating expenses, inventory obsolescence and
asset impairments, competitive pricing pressures, the gain or loss of
significant customers, increased product and process development costs
associated with new product introductions,  the timely completion of
construction and installation of new manufacturing equipment, the timely
completion, testing, acceptance and shipment of equipment manufactured for sale,
and general economic conditions.  All of the above factors are difficult for the
Company to forecast, and these


                                          19
<PAGE>


or other factors may materially adversely affect the Company's business and
operating results for one quarter or a series of quarters.  The Company's
current expense levels are based in part on its expectations regarding future
revenues and in the short term are fixed to a large extent.  Therefore, the
Company may be unable to adjust spending in a timely manner to compensate for
any unexpected revenue shortfall.  Accordingly, any significant decline in
demand relative to the Company's expectations or any material delay of customer
orders would have a material adverse effect on the Company's financial 
condition, cash flows, and operating results.

                          REPORT OF INDEPENDENT ACCOUNTANTS

Board of Directors and Shareholders
Photran Corporation
Lakeville, Minnesota

We have audited the accompanying balance sheets of Photran Corporation (the
Company) as of December 31, 1995 and 1996 and the related statements of
operations, shareholders' equity, and cash flows for the years then ended.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

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

In our opinion, such financial statements present fairly, in all material
respects, the financial position of Photran Corporation as of December 31, 1995
and 1996 and the results of its operations and its cash flows for the years then
ended, in conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming the Company 
will continue as a going concern. As discussed in Note 1 to the financial 
statements, the Company's accumulated losses of $8,718,768 since 
incorporation and negative cash flows from operating activities of $1,478,877 
for the year ended December 31, 1996 raise substantial doubt about the 
Company's ability to continue as a going concern. Management's plans 
concerning these matters are described in Note 1. These financial statements 
do not include any adjustments that might result from the outcome of this 
uncertainty.

PHOTRAN CORPORATION

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1995 AND 1996

- --------------------------------------------------------------------------------


1.  BUSINESS AND MANAGEMENT'S PLANS REGARDING OPERATING LOSSES AND SUMMARY OF 
    SIGNIFICANT ACCOUNTING POLICIES
      BUSINESS - Photran Corporation (the Company) is engaged in the manufacture
    and sale of products incorporating thin film coatings which consist of
    microscopic layers of metal and metal oxide materials.  Materials coated
    with these thin film coatings are components in a wide variety of products,
    including liquid crystal displays, enhanced reflection mirrors and anti-
    reflective glass.  To date, the Company's sales have consisted of coated 
    glass products to a limited number of companies located in Asian countries 
    for use in liquid crystal displays.

    MANAGEMENT'S PLANS REGARDING OPERATING LOSSES

    The Company has incurred accumulated losses aggregating $8,718,768 since 
    its inception. The Company incurred negative cash flows from operating 
    activities of $1,478,877 for the year ended December 31, 1996.
    The Company had cash outlays for property and equipment additions of 
    $8,896,744 for the year ended December 31, 1996.

    At December 31, 1996 the Company had customer deposits of $2,260,420. 
    $1,735,000 of that amount is the deposit payment from the Company's 
    Chinese joint venture partner for the purchase of equipment. That 
    equipment purchase agreement has been canceled and the joint venture 
    partner has commenced arbitration proceedings claiming approximately 
    $4.4 million. (including the $1.7 million discussed above) In addition, 
    the Company has received a deposit of $500,000 from a customer for the 
    purchase of a coating line for which the related contract is in default. 
    The customer has delayed shipment of the equipment and the Company is 
    currently in the process of negotiating amendments to the purchase contract.
    If the Company is not successful in amending the contract and the equipment 
    is not shipped the deposit may have to be refunded.

    The Securities and Exchange Commission has informed the Company that it 
    is conducting an investigation with respect to certain fianncial and 
    accounting irregularities announced by the Company in March 1997 relating 
    to fiscal 1996. The investigation is in the preliminary stages and it is 
    impossible to determine what impact, if any, the investigation will have 
    on the Company's financial condition or results of operations.

    These factors, among others, indicate the Company may be unable to 
    continue as a going concern for a reasonable period of time. The 
    Company's continuation as a going concern is dependent on its ability to 
    meet its obligations as they become due and ultimately attain sales and 
    operating levels to support its cost structure.

    The accompanying financial statements do not include any adjustments 
    relating to the recoverability and classification of recorded asset amounts 
    or the amounts and classification of liabilities that might be necessary 
    should the Company be unable to continue as a going concern. Management's 
    plans regarding operating losses and its plans concerning the above matters 
    are presented below.

    As of December 31, 1996, the Company's principal sources of liquidity 
    included cash and cash equivalents of $2,038,955 and net accounts 
    receivable of $606,500. The Company believes that its existing sources 
    of liquidity and anticipated funds from operations, including the 
    available proceeds from a first quarter 1997 sale-leaseback accounted 
    for as a financing transaction of $2,250,000, will satisfy the Company's 
    projected working capital and capital expenditure requirements for 1997. 
    Management is, however, also investigating the possibility of obtaining 
    working capital financing, although there can be no assurance that such 
    financing will be available or be available on terms acceptable to the 
    Company.
    
    New product introductions will depend on the success of the Company's 
    development efforts and on the results of management's analysis of 
    market opportunities and capital expenditure requirements. The Company's 
    ability to increase revenues is highly dependent on its ability to 
    complete the installation of additional coating equipment. The capital 
    expenditures related to such installation are expected to be available 
    from internally generated funds, including proceeds from the sale of ITO 
    coating equipment to the Company's largest customer. If the Company is 
    unable to finalize the contract amendments currently under discussion 
    with that customer, it intends to keep the equipment for its own use; 
    the loss of equipment sales revenue associated with this transaction, 
    together with a refund of the customer's down payment of $500,000, 
    however, would force the Company to slow the process of installing 
    additional equipment, and possibly force it to seek external capital to 
    fund necessary capital expenditures. Barring any unforeseen adverse 
    external developments, however, management believes that the Company's 
    new plan, which will build on the Company's asset base and technology 
    position, will provide for the growth in revenue and earnings necessary 
    for the long-term financial health of the Company.

    SIGNIFICANT ACCOUNTING POLICIES

    MANAGEMENT'S USE OF 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 and liabilities and disclosure of contingent assets and
    liabilities at the date of the financial statements and the reported
    amounts of revenues and expenses during the reporting period.  Actual
    results could differ from those estimates.

    REVENUE RECOGNITION - Revenues for coated glass sales are recognized upon
    shipment of products to customers.  Contracts for the sale of equipment
    are accounted for using the completed contract method (see Note 2).

    REVENUE FROM SIGNIFICANT CUSTOMERS - Substantially all of the Company's
    sales for the years ended December 31, 1995 and 1996 were to customers
    located in Asian countries.  The percentages of total revenue from sales to
    customers in excess of 10% of the total for each year were as follows:

                                                           1995      1996

    Customer A                                             57%       87%
    Customer B                                             28         -

    PROCESS AND PRODUCT DEVELOPMENT - Expenditures for research and development
    of products and manufacturing processes are expensed as incurred.  Research
    and development expense was $353,636 and $455,847 for the years ended
    December 31, 1995 and 1996, respectively.

    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's accounts receivable at December 31,
    1995 and 1996 are  due primarily from foreign customers located in Asian
    countries.  In 1995, the Company required the establishment of irrevocable
    letters of credit in its favor from approved banks prior to shipment of the
    products underlying these accounts receivable in order to reduce its
    exposure to bad debts.  At December 31, 1996, $338,000 of accounts
    receivable from foreign customers were not secured by letters of credit.
    These accounts were due from customers with whom the Company has had a
    creditor relationship for over one year.



                                          27
<PAGE>


    The percentage of gross receivables due from customers in excess of 10% of
    the December 31 balance is as follows:

                                                           1995      1996

    Customer A                                             67%       49%
    Customer B                                              -        48
    Customer C                                             30        -


    INVENTORY - Inventory is valued at the lower of cost, determined on the
    first-in, first-out method, or market value.  Inventory at December 31
    consists of the following:

                                                     1995          1996

      Raw materials and supplies, at cost        $ 1,420,048    $ 1,117,569
      Finished goods                                                 34,892
                                                 -----------    -----------
                                                   1,420,048      1,152,461
      Less:  Obsolescence reserve                                   397,889
                                                 -----------    -----------
      Net inventory                              $ 1,420,048    $   754,572
                                                 -----------    -----------
                                                 -----------    -----------

    Inventories are periodically reviewed for obsolescence, overstock, and
    quality defects by physical examination and by comparing quantities on hand
    to forecasted future requirements.  Items considered obsolete or overstock
    are written off.  Items with quality defects are valued at net realizable
    value.  In the fourth quarter of 1996, the Company determined that certain
    glass inventory which the Company had successfully coated and sold earlier
    in 1996 had become stained by the packaging materials.  The multiple
    washings which this glass required and the poor quality of output and high
    scrap rates have made it economically unfeasible to attempt to coat this
    glass.  Management has established an obsolescence reserve of $397,889,
    which has been charged to cost of sales in the fourth quarter to reduce the
    carrying value of this glass to its estimated net realizable value if sold
    as uncoated scrap.

    The Company purchases substantially all of its raw glass, which is the
    majority of the raw materials used in the manufacture of its products, from
    a single source supplier.  The Company believes that acceptable alternative
    sources of this material are available.

    EQUIPMENT HELD FOR SALE - Equipment held for sale is carried at cost. 
    Equipment held for sale includes $85,000 and $59,000 of interest capitalized
    for the years ended December 31, 1995 and 1996, respectively.

    CUSTOMER ADVANCES - Customer advances represent amounts received from
    customers as down payments on equipment contracts.  (See Note 2).

    PROPERTY AND EQUIPMENT - Property and equipment are recorded at cost.  Cost
    includes expenditures for new equipment and incremental labor and direct
    costs incurred for construction of equipment modifications.  Property and
    equipment include $209,000 of interest capitalized during the year ended
    December 31, 1996.  Property, other than manufacturing process equipment,
    is depreciated using the straight-line method over estimated useful lives
    of three to ten years.  Manufacturing process equipment is depreciated
    using the units-of-production method, with such equipment's useful life
    estimated to be approximately ten years.  Amortization of equipment under
    capital leases is over the shorter of the lease term or the economic useful
    life and is recorded as depreciation expense.  Depreciation is not recorded
    on property not yet placed in service.  Repairs and maintenance are charged
    to expense as incurred.

    DEFERRED FINANCING COSTS - Deferred financing costs at December 31, 1995
    consisted primarily of underwriting and legal fees associated with the
    issuance of bridge note financing in fiscal 1995 (see Note 4).  Accumulated
    amortization was $40,000 at December 31, 1995.  The unamortized balance was
    written off upon repayment of the Bridge Notes in 1996, and has been
    classified as an extraordinary item in the statements of operations.

    OTHER ASSETS - The Company has obtained patent rights to various
    manufacturing processes and product technology.  The founding shareholder
    has transferred key manufacturing and product technology to the Company,
    including patent rights, for the sum of $1.  Through December 31, 1995 and
    1996, there were no sales of product subject to royalty.  In addition, the
    Company had purchased and capitalized an exclusive license for certain
    related technology from Applied Elastomerics, Inc. for $13,000 which was to
    be amortized upon commencement of production over the term of the license
    agreement.  The license expired in May 1996 and was not renewed.

    IMPAIRMENT OF LONG-LIVED ASSETS - Management periodically reviews the
    carrying value of property and equipment and other long-lived assets for
    potential impairment by comparing its carrying value to the estimated
    undiscounted future cash flows expected to result from the use of these
    assets.  Should the sum of the related expected future net cash flows be
    less than the carrying value, an impairment loss is recognized.  An
    impairment loss is measured by the amount by which the carrying value of
    the asset exceeds the fair value of the asset.

    As of December 31, 1996, the Company reassessed the carrying values of the
    fixed assets related to several production projects in relation to the
    expected future cash flows from sales of the manufactured products.  The
    Company decided that it would refocus its efforts with respect to such
    projects and would not pursue those for which commercial production did not
    appear feasible in the near term.  The related fixed assets were,
    therefore, written down to their estimated fair values, which in some cases
    were determined by their historical cost less a restocking fee to the
    extent that the Company could return purchased components to the
    manufacturer.  (See Note 8).

    The value of the license rights was deemed impaired as of December 31, 1996,
    and the costs were written off.  These charges are included within other
    nonrecurring charges in the statements of operations.

    INCOME TAXES - The Company calculates income taxes in accordance with the
    provisions of Statement of Financial Accounting Standards (SFAS) No. 109,
    ACCOUNTING FOR INCOME TAXES.  SFAS No. 109 requires an asset and liability
    approach to financial accounting and reporting for income taxes.  Deferred
    income tax assets and liabilities are computed annually for differences
    between the financial statement and tax basis of assets and liabilities
    that will result in taxable or deductible amounts in the future based on
    enacted tax laws and rates applicable to the period in which the
    differences are expected to affect taxable income.

    NET INCOME (LOSS) PER COMMON AND COMMON EQUIVALENT SHARE - Net income 
    (loss) per common and common equivalent share is computed by dividing 
    net income (loss) by the weighted average number of common stock and 
    dilutive common stock equivalents outstanding.  The weighted average 
    number of common and common equivalent shares outstanding has been 
    adjusted to give retroactive effect to the reverse stock split 
    authorized by the Company's shareholders on March 2, 1996.  Common stock 
    equivalents result from dilutive stock options and warrants.  Common 
    stock equivalents are not included in the per share calculations when 
    the effect of their inclusion would be antidilutive, except that, in 
    accordance with Securities and Exchange Commission (SEC) requirements, 
    common and common equivalent shares issued during the 12 months prior to 
    the Company's initial public offering have been included in the 
    calculation (using the treasury stock method based on an initial public 
    offering price of $9.00 per share for all prior periods presented).


                                          29

<PAGE>

    Fully diluted earnings (loss) per common share is not presented because of
    its antidilutive effect.

    STOCK-BASED COMPENSATION - SFAS No. 123, ACCOUNTING  FOR STOCK-BASED
    COMPENSATION, requires expanded disclosures of stock-based compensation
    arrangements with employees and encourages (but does not require)
    application of the fair value recognition provisions of SFAS No. 123 to
    such arrangements.

    The Company has chosen to continue to account for stock-based compensation
    using the intrinsic value method prescribed in Accounting Principles Board
    Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES, and related
    Interpretations.  Accordingly, compensation cost for stock options is
    measured as the excess, if any, of the quoted market price of the Company's
    stock at the date of the grant over the amount an employee must pay to
    acquire the stock.  (See Note 7).

    FINANCIAL RISKS AND UNCERTAINTIES - The Company has disclosed in the 
    financial statements certain financial risks and uncertainties to which 
    it is subject:  concentration of sales to a limited number of customers; 
    single source supplier of raw materials; and use of estimates to review 
    the carrying value of long-lived assets and equipment held for sale 
    which may change in the future given the rapid technological changes 
    associated with the industry in which the Company operates.  Also, the 
    Company has a contract for the sale of a thin film coating machine to 
    its largest customer, which is in default (see Note 2).  If the contract 
    is completed and the equipment is used by the customer to satisfy a 
    significant portion of the customer's need for ITO-coated glass, the 
    Company will need to find additional customers to replace this source of 
    revenue.

    The technology used in the Company's manufacturing equipment may be subject
    to rapid technological change within time frames not currently anticipated
    by the Company.  It is reasonably possible that the Company's estimate of
    recoverability of the carrying value of its equipment will change in the
    future.

2.  EQUIPMENT CONTRACTS AND EQUIPMENT HELD FOR SALE

    In 1994, the Company entered into a joint venture agreement with the
    Shenzhen WABO Group Company, Limited (WABO) of Shenzhen, China.  The joint
    venture company, known as the Shenzhen Fortune Conductive Glass Company,
    Ltd. (Fortune), was created to produce TN-grade ITO-coated glass for the
    Asian market.

    WABO provided cash to Fortune to purchase a glass coating system from the
    Company and for working capital purposes.  The Company was obligated to
    provide $4,658,000 (40% of the total capitalization of the joint venture of
    $11,645,000).  The Company agreed to sell to Fortune the ITO glass coating
    machine for $10,145,000.  The Company's contribution of $4,658,000 was to
    have been deducted from the gross purchase price of the coating system.
    The Company was recording the net purchase price of $5,487,000 ($10,145,000
    - $4,658,000) as an equipment sale.  The Company was following the
    provisions of Emerging Issues Task Force (EITF) Issue No. 89-7 in
    accounting for the glass coating system sale.  EITF 89-7 offers guidance
    regarding gain recognition on sales to joint venture companies by a joint
    venture partner and accounting for the company's investment in the joint
    venture.  The Company was accounting for the sale of the glass coating
    system using the completed contract method and has recorded the down
    payment of $1,530,000 as a customer advance.  All costs incurred in
    constructing the equipment were classified as equipment held for sale at
    December 31, 1995.

    The equipment was scheduled to ship in April 1996, and the Company was
    liable for various penalties for failure to ship by April 15, 1996, which
    had been verbally waived by WABO provided the equipment was


                                          30
<PAGE>


    shipped by June 30, 1996.  Due to various technical modifications 
    requested, the equipment had not shipped by September 30, 1996.  During 
    the quarter ended December 31, 1996, the Company attempted to resolve 
    the issues regarding payment of late delivery penalties as well as 
    payment for the various technical modifications.  The Company had 
    negotiated with representatives of WABO and had drafted an amendment to 
    the agreement in which all penalties for late delivery were waived in 
    exchange for the technical modifications being provided at no charge.  
    The Company was subsequently informed by WABO of their intention to 
    dissolve the joint venture and cancel the related equipment purchase 
    contract.  The Company intends to keep the glass coating system and is 
    currently in the process of modifying the system for its own use.  All 
    costs incurred for the machine were reclassified to construction-in-
    progress during the quarter ended December 31, 1996. The Company has 
    recorded a liability of approximately $200,000 related to glass which was 
    provided by WABO for use in testing the system.  The Company and WABO are 
    currently in disagreement as to cancellation of the contract and dissolution
    of the joint venture. (See Note 6).

    In 1996, the Company entered into an agreement to sell ITO coating 
    equipment to its largest customer for a total contract price of 
    $2,916,500. The Company received a down payment of $500,000 which is 
    recorded as a customer advance at December 31, 1996. Delivery of the 
    equipment was originally scheduled for the fourth quarter of 1996.  This 
    delivery has been delayed, and the customer has requested the Company to 
    install and operate the equipment in the Company's facilities during 
    1997.  The Company is in the process of negotiating contract amendments 
    to extend the delivery date and clarify payment terms in light of the 
    changed nature of the agreement.  This amendment has not yet been 
    finalized. Costs incurred to date have been classified as equipment held 
    for sale as of December 31, 1996.

4.  NOTES PAYABLE, LONG-TERM DEBT, AND CAPITAL LEASE OBLIGATIONS

    Notes payable, long-term debt, and capital lease obligations at December 31
    consist of the following:


                                                      1995            1996

    Less current maturities                           (1,041,547)      (51,592)
                                                     -----------     ---------
    Long-term debt                                   $   762,783     $ 327,813

                                                     -----------     ---------


    The carrying amounts of long-term debt approximate fair market value on
    December 31, 1995 and 1996, respectively.  Rates currently available to the
    Company for debt with similar terms and remaining maturities are used to
    estimate the fair value of the existing debt.

         (A)  In October 1995, the Company issued $4 million of notes payable
         (the Bridge Notes).  The Bridge Notes bore interest at 11.75% per
         annum with interest and principal due the earlier of October 15, 1996
         or the receipt by the Company of gross proceeds of at least $7 million
         in a private or public financing that includes securities with equity
         features or debt with a term of one year or more.  The Bridge Notes
         were repaid in June 1996 with proceeds from the Company's initial
         public offering.

         In connection with this financing, the Company issued warrants to the
         purchasers of the Bridge Notes to purchase a total of 400,000 shares
         of the Company's common stock and issued warrants to the selling agent



                                          32
<PAGE>


         of the Bridge Notes to purchase a total of 40,000 shares of the 
         Company's common stock.  See Note 7 for a description of the 
         terms of these warrants.

         (B)  During fiscal 1995, the Company obtained a $2,000,000
         transaction-specific line of credit ($1,916,480 outstanding at
         December 31, 1995) through the Bank of America, guaranteed by the
         Export Import Bank (EXIM) of the United States.  Under terms of the
         line of credit, proceeds from this borrowing were to be used by the
         Company to complete the coating system equipment which was to be sold
         to the joint venture (see Note 2).  Borrowings bore interest at 1%
         over prime (9.5% at December 31, 1995) and were secured by the
         equipment held for sale and all other current assets.  The borrowings
         were repaid from the proceeds of the initial public offering.

         (C)  The EXIM guarantee was extended to a $500,000 revolving line of
         credit ($225,000 outstanding at December 31, 1995).  This line of
         credit was to be used to finance products for export.  Borrowings bore
         interest at a rate of 1% over prime (9.5% at December 31, 1995) and
         were secured by accounts receivable and inventory.  The line was
         repaid with the proceeds of the initial public offering.

         (D)  On May 1, 1995, a director of the Company made a loan to the
         Company in the original principal amount of $1.5 million.  The loan
         bore interest at prime plus 3.75% (12.25% at December 31, 1995) and
         was secured by substantially all equipment and intellectual property
         of the Company.  The Company incurred costs of approximately $10,000
         relating to the issuance of the note.  These costs were being
         amortized, on a straight-line basis, from the date of issuance until
         May 10, 1997, which was the original maturity date of the note.  The
         note was repaid with the proceeds of the initial public offering.  In 
         connection with the issuance of this loan, warrants were issued to the 
         director to purchase up to 75,000 shares of the Company's common stock.
         See Note 7 for a description of the terms of these warrants.

         (E)  The $200,000 shareholder note payable bears interest at 10%, is
         unsecured, and is convertible, at the shareholder's option, into
         shares of the Company's common stock at a conversion rate of $2.00 per
         share.  The note is due January 1998.  In connection with the issuance
         of this loan, warrants were issued to the director to purchase up to
         20,000 shares of the Company's common stock, exercisable from August
         1994 to August 1997, at an exercise price of $2.00 per share.
         Interest payable on this note was $47,500 and $67,500 at December 31,
         1995 and 1996, respectively.

         (F)  Capital lease obligations are secured by the underlying property
         and bear interest at effective interest rates of approximately 8.75%
         to 15.70%.

                                     ----------    ---------       ---------

    Total interest, including amortization of financing fees, incurred in 1995
    and 1996 was approximately $384,000 and $605,000, respectively.  Of these
    amounts, approximately $85,000 and $268,000 were capitalized to
    construction-in-progress or equipment held for sale during 1995 and 1996,
    respectively.

5.  INCOME TAXES

    For income tax purposes, the Company has U.S. federal net operating loss
    carryforwards of approximately $6,500,000 as of December 31, 1996.  The
    carryforwards expire in various amounts during the years 2006 through 2010.

    Due to certain ownership changes, as defined in Section 382 of the Internal
    Revenue Code, which occurred during the year ended December 31, 1993, the
    Company's net operating loss carryforwards incurred through February 1993
    of approximately $700,000 are limited to annual utilization of
    approximately $50,000 per year.

    Utilization of the Company's net operating loss carryforwards was not
    limited as a result of its public offering in June 1996.  However, the
    Company's ability to use its net operating loss carryforwards may be
    further limited by subsequent issuances of common stock.

    The benefit for income taxes in fiscal 1996 has been offset by a valuation
    allowance because future realization of the net operating loss
    carryforwards is uncertain.  The Company utilized net operating loss
    carryforwards in fiscal 1995 to substantially offset any taxes due.

 6.  COMMITMENTS AND CONTINGENCIES

    OPERATING LEASE COMMITMENTS - The Company is obligated under a
    noncancelable operating lease for the rental of its office and
    manufacturing facility through July 2001.  The lease contains provisions
    for payment of the facility operating expenses and real estate taxes as
    additional rents.  The Company has the option to terminate the lease on the
    fifth anniversary of the commencement of the lease by providing 120 days
    written notice to the lessor, with a penalty.  During January 1996, the
    Company entered into an operating lease to rent additional manufacturing
    space for a term of ten years.  This lease contains provisions for payment
    of the facility operating expenses and real estate taxes as additional
    rents.  Rent expense for the years ended December 31, 1995 and 1996 was
    approximately $100,000 and $150,000, respectively.  Minimum lease payments
    due under these operating leases for the next five years are as follows:

    Year ending December 31:
         1997                                                 $  221,610
         1998                                                    221,610
         1999                                                    221,610
         2000                                                    221,610
         2001                                                    185,672

    EMPLOYMENT AGREEMENT - The Company had executed an employment agreement
    with its president, who resigned in March 1997.  The agreement, which
    expires December 31, 1997, provided for a maximum base compensation of
    $120,000 per year if certain financial performance goals, as set by the
    Company's Board of Directors, were met.  The agreement also provided for
    the issuance of options, at the discretion of the Board of Directors, for
    the purchase of the Company's common stock, payment of annual incentive
    bonuses, and an option for the president to require the Company to purchase
    his shares if the Company terminated his employment without cause prior to
    an initial public offering of the Company's common stock.  Options for the
    purchase of 25,000 shares of the Company's common stock have been issued
    pursuant to this agreement.  The Company's obligation under the agreement
    terminated in March 1997 when the president resigned.

    CONTINGENCIES - During the quarter ended December 31, 1996, the Company was
    informed by WABO of their intention to dissolve the joint venture and cancel
    the related equipment purchase contract.  In April 1997, the Company 
    received notice that arbitration proceedings have been commenced against it 
    by WABO, claiming approximately $4.4 million plus legal fees and costs.  
    This process is still in a very early stage, and it is too soon to determine
    whether the Company will be liable for any additional amounts


                                          35
<PAGE>


    beyond the return of amounts which are recorded as customer deposits (see
    Note 2).  It is possible that additional amounts determined to be due upon 
    final resolution of this matter could be material to the financial 
    position, cash flows and operating results of the Company.

    In connection with the coating equipment that the Company was building for
    sale to Fortune, the Company entered into a contract with a third party to
    design and build power supplies to be sold under the equipment contract, as
    well as for the Company's own use.  The third party has asserted that the
    Company is liable to it for various costs incurred in connection with the
    production of the power supplies and has demanded payment of $240,000 in
    addition to amounts the Company has already paid under the contract.  Due
    to various defects in the contract as well as the third party's failure to
    perform its obligations, the Company has rescinded the contract and
    demanded that the third-party refund all monies paid to it by the Company.
    Management, in consultation with the Company's legal counsel, is of the
    opinion that the Company has valid defenses against the claims asserted by 
    the third party. However, it is possible that the Company will be liable for
    amounts in addition to those already paid under the contract. Such amounts 
    could be material but the Company is unable to estimate what amounts, if 
    any, will ultimately be paid.

    The SEC has informed the Company that it is conducting an investigation with
    respect to certain financial and accounting irregularities announced by the 
    Company in March 1997 relating to fiscal 1996.  The Company has submitted 
    documents to the SEC pursuant to requests from the SEC as part of the 
    investigation.  The investigation is in the preliminary stages and it is 
    impossible to determine what impact, if any, the investigation will have on 
    the Company's financial condition or results of operations.

7.  SHAREHOLDERS' EQUITY

    INITIAL PUBLIC OFFERING - On May 29, 1996, the Company sold 2,000,000
    shares of common stock in an initial public offering.  In connection with
    this offering, the Company issued an overallotment option to the
    underwriters to purchase up to 300,000 shares solely to cover
    overallotments.  This option was exercised in June 1996.  Total net
    proceeds to the Company of the initial offering and the overallotment
    option were $18,451,628 after deducting offering costs of $2,248,372.

    SUPPLEMENTARY EARNINGS PER SHARE - The Company utilized approximately
    $7,500,000 of the net proceeds from the initial public offering to retire
    debt and lines of credit outstanding.  Had the Company issued a sufficient
    number of shares to retire this debt, approximately 940,000 shares at a net
    price of $8.04 per share after deducting offering costs, as of January 1,
    1996, the net loss for the year would have been reduced by approximately
    $125,000 in interest expense on these borrowings, and supplementary earnings
    per share for the year ended December 31, 1996 would have been $(1.13).

    AUTHORIZED SHARES - On March 2, 1996, the Company's shareholders approved
    an amendment to the Company's Articles of Incorporation whereby the
    authorized stock of the Company was stated as 24,000,000 shares of common
    stock, no par value, and 6,000,000 undesignated shares, no par value.  The
    Company's Board of Directors may designate any series and fix any relative
    rights and preferences of the undesignated stock.  The authorized shares
    have been restated in the financial statements to reflect the impact of
    this amendment.

    REVERSE STOCK SPLIT - On March 2, 1996, the Company's shareholders approved
    a one-for-two reverse stock split.  The reverse stock split became
    effective on May 29, 1996 when the initial public offering of the Company's
    common stock became effective.  All share and per share amounts included in
    the financial statements and notes thereto have been restated to reflect
    the impact of the reverse stock split.

    STOCK OPTION PLAN - On March 2, 1996, the Company's shareholders approved
    the amendment of the Company's 1992 Stock Option Plan (the Plan) to provide
    for the issuance of up to 625,000 shares of the Company's common stock
    under the Plan.  Under the Plan, incentive stock options and nonqualified
    stock options may be granted to key employees and others at exercise prices
    not less then 85% of the fair market


                                          36

    value of the underlying common stock at the date of grant.  The Board of
    Directors establishes all terms and conditions of each grant.  The
    following summarizes stock option activity related to the Plan:

    During 1994, the Board of Directors granted an option to an unrelated party
    to purchase 6,875 shares of the Company's common stock at an exercise price
    of $4.00 per share.  Options to purchase 2,500 shares of common stock were
    exercised during 1995.  Options to purchase 4,375 shares expired during
    1995.

    During 1995, the Board of Directors granted currently exercisable options
    to purchase 5,000 shares of common stock at $4.00 per share to each outside
    member of the Board of Directors (for options to purchase an aggregate of
    15,000 shares of common stock).  In addition, the Board of Directors
    granted options to purchase 15,000 shares of common stock at $4.00 per
    share to each outside member of the Board of Directors (for options to
    purchase an aggregate of 45,000 shares of common stock), which vest over a
    three-year period commencing March 15, 1996.  All options granted to
    members of the Board of Directors expire ten years after the date of grant.
    Ten thousand of such options which had not vested expired during March 1996
    upon the resignation of a member of the Board of Directors.

    The Company has adopted the disclosure-only provisions of SFAS No. 123,
    ACCOUNTING FOR STOCK-BASED COMPENSATION.  Accordingly, no compensation cost
    has been recognized for the stock options.  Had compensation cost for the
    Company's stock option plan been determined based on the fair value at the
    grant date for awards vesting in 1995 and 1996 consistent with the 
    provisions of SFAS No. 123, the Company's net income (loss) and income 
    (loss) per share would have been reduced (increased) to the proforma amounts
    indicated below:

    The fair value of each option grant is estimated on the date of grant using
    the Black-Scholes option-pricing model with the following weighted average
    assumptions used for grants in 1995 and 1996: dividend yield of 0%;
    expected volatility of 0%, as only grants prior to the Company's initial
    public offering have vested in either year; risk-free interest rate of
    5.75% to 6.75%; and expected lives of 10 years.

    (A)  These warrants were issued in connection with the issuance of Bridge
    Notes during fiscal 1995.  In connection with this financing, the Company
    issued warrants to the purchasers of the Bridge Notes to purchase a total
    of 400,000 shares of the Company's common stock and to the selling agent of
    the Bridge Note financing warrants to purchase a total of 40,000 shares of
    the Company's common stock.  The holders of the warrants may convert the
    warrants, at any time during the exercise period, into the number of shares
    of the Company's common stock obtained by dividing the differential between
    the then-current market price of the Company's common stock, as defined,
    and the warrant exercise price by such current market price of the
    Company's common stock.  The Company has obtained a valuation of the
    warrants and has determined, based on such valuation, that the value of the
    warrants, if any, is insignificant to the financial statements.

    In connection with a $1,500,000 loan received in May 1995 from a director
    of the Company, warrants were issued to the director to purchase up to
    75,000 shares of the Company's common stock at an exercise price of $4.00
    per share.  The Company has obtained a valuation of the warrants and has
    determined, based on such valuation, that the value of the warrants, if
    any, is insignificant to the financial statements.

8.  OTHER NONRECURRING CHARGES

    In the fourth quarter of 1996, the Company's joint venture partner, WABO,
    notified the Company of its intention to cancel the joint venture agreement
    and the related equipment purchase contract.  In connection with the
    cancellation of the equipment purchase contract, the Company determined
    that certain equipment which was to have been sold to Fortune and was also
    under development for the Company's own use was no longer economically
    feasible or did not fit the Company's current manufacturing needs.  This
    equipment has been written down to its fair value, which in some cases was
    determined as its cost less a restocking charge to the extent such
    equipment can be returned to the manufacturer.  Equipment which had no
    foreseeable future value was written off.  This resulted in a charge of
    approximately $1,800,000 in the fourth quarter of 1996.

    Also, the Company decided to discontinue its development of commercial
    scale production equipment for its ZeroRay Glare and Radiation Control
    filters due to technical difficulties encountered with the large


                                          38
<PAGE>


    scale production of the Gelglas optical gel adhesive.  Management believes
    that the resolution of these technical difficulties would have required
    significant additional resources and would have raised the cost of the
    filters to a point where the product could not be competitive with other
    similar products.  In connection with this decision, management determined
    that, as of December 31, 1996, certain production equipment which had been
    purchased to manufacture the ZeroRay product had been impaired.  This
    equipment was determined to have no foreseeable future value and was
    written off.  This resulted in a charge of approximately $378,000 in the
    fourth quarter of 1996.

    In addition, the Company determined that as a result of refocusing of its
    operations, a piece of manufacturing equipment had little future value to
    the Company at December 31, 1996.  The machine has been written down to its
    fair value, resulting in an impairment charge of approximately $272,000 in
    the fourth quarter of 1996.

9.  SUPPLEMENTAL CASH FLOW DISCLOSURES

    Cash paid for interest was $146,492 and $484,160 for the years ended
    December 31, 1995 and 1996, respectively.  Property acquired by capital
    lease was $128,466 and $40,083 for the years ended December 31, 1995 and
    1996, respectively.

    As a result of the equipment sales contracts discussed in Note 2, assets
    classified as equipment held for sale to Fortune at December 31, 1995 are
    classified within property, plant, and equipment at December 31, 1996.  All
    expenditures related to the Fortune contract during 1996 are classified as
    cash flows from investing activities.  Conversely, equipment held for sale
    at December 31, 1996 had been classified within property, plant, and
    equipment at December 31, 1995.  All expenditures related to the contract
    with a customer during 1996 have been classified as operating cash flows.  
    The net effect of the changes in classification of these two assets was a 
    noncash transfer from equipment held for sale to property, plant, and 
    equipment of $2,593,264.

    During 1996, the Company received equipment with an estimated fair value of
    $25,000 from a customer in lieu of payment on accounts receivable.

10. SUBSEQUENT EVENT

    Subsequent to December 31, 1996, the Company entered into a sale-leaseback,
    which will be treated as a financing transaction, for the coating equipment
    in construction-in-progress that was originally intended to be sold to
    Fortune.  Under the terms of the agreement, the Company received proceeds
    of $4.5 million of which $2.25 million is restricted and $2.25 
    million is available to the Company.

    On December 15, 1992, the Board of Directors and shareholders of the

and also nonqualified stock options which do not meet the requirements of such
section.  As amended by the Board of Directors and approved by the shareholders

for issuance upon the exercise of options granted under the Plan.  As of the
date of this report, the Company has outstanding options to purchase an
aggregate of 76,250 shares under the Plan.

COMPENSATION OF DIRECTORS

    Directors were not paid fees for attending meetings in 1996.  All directors
are reimbursed for their travel expenses incurred in attending Board meetings.

    On March 1, 1995,  the Board of Directors granted currently exercisable
options to purchase 5,000 shares of Common Stock at $4.00 per share to each of
three outside members of the Board of Directors (for options to purchase an
aggregate of 15,000 shares of Common Stock) as compensation for prior service to
the Company.  On the same date, the Board of Directors also granted options to
purchase 15,000 shares of Common Stock at $4.00 per share to each of three
outside members of the Board of Directors (for options to purchase an aggregate
of 45,000 shares of Common Stock) as compensation for each outside director's
then current three-year term.  These 45,000 options vest ratably over a three-
year period commencing March 15, 1996.  All options expire ten years after the
date of grant.  Options for 10,000 shares expired in March 1996 upon the
resignation of one of the outside directors.  This director, who is a sitting
judge, resigned prior to the Company's initial public offering due to an ethical
conflict of interest relating to a judge serving on the board of  a public
company.

ITEM 12 - CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

LOANS FROM DIRECTOR

    Steven King, a director of the Company, made a loan to the Company in the
original principal amount of $1.5 million on May 1, 1995 for working capital and
general corporate purposes.  The note issued in connection with the loan bore
interest from the date of issue at an annual rate of 3.75 % in excess of the
"Reference Rate" announced from time to time by First Bank National Association,
and was secured by substantially all equipment and intellectual property of the
Company.  The note was subject to periodic payments of principal and accrued
interest.  The note was prepaid without penalty in June 1996.
    
    In connection with this loan, warrants to purchase up to 75,000 shares of
common stock were issued to Mr. King.  The warrants are exercisable at any time
after April 30, 1996, and expire on May 1, 2003.  The exercise price of these
warrants is $4.00 per share.  The warrants provide for the automatic adjustment
of the number of shares issuable upon exercise of the warrants, and of the
exercise price, in certain events, including stock dividends, stock splits,
reorganizations, reclassifications and the merger, consolidation or sale of all
or substantially all of the assets of the Company.  The warrants grant certain
registration rights with respect to the stock issuable upon exercise of the
warrants in the event the

                        RIDER TO EQUIPMENT LEASE AGREEMENT

    THIS RIDER is entered into by and between Photran Corporation (the
"Lessee") and NBD Equipment Finance, Inc. (the "Lessor") with respect to that
Equipment Lease Agreement of even date herewith (the "Lease"), pursuant to which
the Lessor has agreed to lease to the Lessee and the Lessee has agreed to lease
from the Lessor certain personal property more particularly described in the
Lease (the "Equipment").

    The Lessor has agreed to purchase the Equipment from the Lessee and lease
it back to the Lessee under the terms of the Lease only if the Lessee makes the
additional agreements contained herein and contemplated hereby.

    In consideration of the foregoing, and in order to induce each other to
enter into the Lease, the Lessor and Lessee agree as follows:

    1.   The Lessor is paying to Lessee the amount of $4,500,000.00 (the "Lease
Proceeds") on the date hereof for the Equipment. Of that amount, $2,250,000.00
will be wire transferred to an account designated by the Lessee for the
unrestricted sue by the Lessee (the "Unrestricted Proceeds") and $2,250,000.00
(the "Collateral Proceeds") will be deposited with NBD Bank, N.A. (the "Bank")
to be held as collateral in favor of the Lessor against the Lessee's obligations
under the Lease and under this Rider.

    2.   The Lessee will execute and deliver to the Lessor a separate
Assignment of Deposit Account under which the deposit of the Collateral
Proceeds, and any account into which such Collateral Proceeds is deposited, and
any rollover or replacement account to which such initial deposit is
subsequently credited, will be assigned to the Lessor.

    3.   The Lessee agrees with the Lessor that the Lessee is irrevocably bound
to purchase the Lessor's interest in the Equipment for an amount of
$2,250,000.00, upon the earlier to occur of (i) the end of the normally
scheduled term of the Lease, or (ii) a default under the Lease. Any part of such
purchase obligation which is unpaid after it becomes due will accrue interest at
a rate equal to the rate of interest announced from time to time by the First
National Bank of Chicago as its "Corporate Base Rate", plus three percent (3.0%)
per annum.

    4.   Any sale of the Lessor's interest in the Equipment to the Lessee shall
be as is where is with respect to the Equipment, and shall be without warranty
of any kind with respect to the Equipment, including, without limitation any
warranty of fitness for a particular purpose.

    5.   The element of damages contemplated by Section 13(c)(3) of the Lease
will instead of being the fair market value of the Equipment, be the amount of
$2,250,000.00.

    6.   If any part of the Collateral Proceeds subject to a security interest
in favor of Lessor is used to satisfy any obligation of the Lessee under the
Lease prior to the expiration of its term, the Lessee will deposit additional
cash with the Lessor, or with a third party subject to a lien in favor of the
Lessor, in the amount equivalent to any part of the original Collateral Proceeds
so used. If the amount of deposit collateral subject to a security interest in
favor of the Lessor ever declines below $2,250,000.00, the Lessee will deposit
additional cash with the Lessor, or with a third party subject to a lien in
favor of the Lessor, in the amount equivalent to such deficiency.

<PAGE>

    7.   Excepts as modified by this Rider, the Lease shall remain unchanged
and in full force and effect.

    IN WITNESS WHEREOF, the parties have caused this Rider to be entered into
as of February 13, 1997.

                                  SECURITY AGREEMENT

             SECURITY AGREEMENT AND COLLATERAL ASSIGNMENT WITH RESPECT TO
                          SAFEKEEPING ACCOUNT AND SECURITIES

In order to induce NBD EQUIPMENT FINANCE, INC. (herein referred to as "Lender")
to make certain credit facilities available to PHOTRAN CORPORATION (the
"Borrower") in the aggregate amount of $4,500,000.00 under the terms of an
Equipment Lease Agreement and a related Rider to Equipment Lease Agreement both
of even date herewith (such documents, together with any renewal, extension,
amendment or replacement thereof being hereinafter referred to as the "Lease
Documents") and in order to secure all of Borrower's obligations to Lender under
the Lease Documents, the Borrower has agreed to grant to Lender a security
interest in all of Borrower's security entitlement in Safekeeping Account No.
__________ (the "Account") maintained with NBD BANK, N.A. ("Intermediary") and
in the investment property and financial assets credited to the Account itself.

NOW, THEREFORE, it is agreed by and between the parties hereto as follows:

1.  As security for the obligations of Borrower to Lender under the Lease
Documents, including, without limitation, the repayment of all monies which
Lender may hereafter loan or advance to or for the benefit of the Borrower under
the Lease Documents, up to the dollar amount specified above, Borrower hereby
grants a security interest in and assigns and transfers to Lender all of
Borrower's right, title and interest in any investment property or financial
assets, deposits, certificates of deposit, monies owing to Borrower and funds
which may hereafter accumulate in or become withdrawable from or paid out of
such Account of Borrower with Intermediary, including any balance which may
remain to the credit of said account upon the closing thereof.

2.  Intermediary is hereby authorized and directed to remit to Lender, upon
demand by Lender, all funds that may hereafter be withdrawable or payable out of
the Account of Borrower in the name of Borrower with Intermediary, and Borrower
agrees that Borrower will not withdraw or attempt to withdraw any funds or other
property from such account, except as permitted by this agreement. Lender is
hereby authorized and fully empowered, without further authority from Borrower,
to direct Intermediary to liquidate any or all investment property in such
account and to request Intermediary to remit to Lender, any funds that may be
due to Borrower, and Intermediary is hereby authorized and directed to pay to
Lender such sums as Lender shall so request or demand without the consent of or
notice to Borrower. INTERMEDIARY SHALL MAKE NO DISBURSEMENTS DIRECTLY TO
BORROWER, OTHER THAN FROM DIVIDEND AND INTEREST INCOME GENERATED BY THE
INVESTMENT PROPERTY AND FUNDS IN THE ACCOUNT, WITHOUT INQUIRY OF OR NOTICE TO
LENDER AND THE CONSENT OF LENDER. UNLESS NOTIFIED TO THE CONTRARY IN WRITING BY
LENDER, INTERMEDIARY MAY MAKE DISTRIBUTIONS TO BORROWER OF INTEREST INCOME
GENERATED BY ASSETS IN THE ACCOUNT AT ANY TIME WITHOUT NOTICE TO OR CONSENT OF
LENDER.

3.  Borrower hereby constitutes and appoints Lender as Borrower's true, lawful
and irrevocable attorney-in-fact to demand, receive and enforce payments and to
give receipts, releases, satisfactions for, and to sue for all monies payable to
Borrower by Intermediary, and Borrower agrees that this may be done in the name
of Lender with the same force and effect as Borrower could do had this Agreement
not been made.  Any and all monies or payments which may be received by
Borrower, to which Lender is entitled under and by reason of this Agreement,
will be received by Borrower as trustee for Lender, and will be immediately
delivered, in kind, to Lender without commingling.

4.  BORROWER MAY NOT EXECUTE ANY SALE TRANSACTIONS IN THE ACCOUNT AND
INTERMEDIARY MAY NOT ACCEPT FOR EXECUTION ANY SUCH TRANSACTIONS WITHOUT NOTICE
TO AND THE CONCURRENCE OF LENDER. THE PROCEEDS OF ANY SUCH SALE, INCLUDING ANY


                                          1


<PAGE>

ASSET IN WHICH THE PROCEEDS ARE REINVESTED, WILL REMAIN IN THE ACCOUNT, WILL NOT
DISTRIBUTED TO BORROWER, AND WILL REMAIN SUBJECT TO THE SECURITY INTEREST
CREATED UNDER THIS AGREEMENT. ANY ASSET WHICH CONSISTS OF A MATURED DEBT OWED TO
BORROWER, SUCH AS BILLS, NOTES, BONDS OR CERTIFICATES OF DEPOSIT, MAY BE
REINVESTED IN AN ASSET OF LIKE QUALITY AND MATURITY, WITHOUT ANY NOTICE TO OR
INQUIRY OF THE LENDER SO LONG AS THE REPLACEMENT INVESTMENT REMAINS IN THE
ACCOUNT AND IS SUBJECT TO THE SECURITY INTEREST CREATED UNDER THIS AGREEMENT.

5.  Upon the occurrence of a default under the terms of the Lease Documents,
Lender shall be entitled without the consent or concurrence of Borrower, to
direct Intermediary to liquidate any or all then outstanding (investment
property or financial assets) in Borrower's Account and to direct Intermediary
to pay Lender such credit balance as shall exist in the Account after such
liquidation and after the payment to Intermediary of all the indebtedness of
Borrower to Intermediary in connection with transactions in such Account.

6.  Any sums paid under this Agreement by Intermediary to Lender from the
accounts of Borrower shall be applied by Lender to the payment of the
obligations owing by Borrower to Lender under the Lease Documents. The balance,
if any, remaining after the payment of said obligations shall be paid by Lender
to Borrower. The receipt or receipts of Lender for such funds so paid to it by
Intermediary shall, as to Intermediary, operate as the receipt of Borrower as
fully and as completely as if funds had been paid to Borrower in person and
receipted for by Borrower. The liens created by this Agreement shall be junior
to the liens claimed by Intermediary for indebtedness owed to Intermediary by
Borrower.

7.  Lender is hereby authorized and empowered to receive from Intermediary, and
Intermediary is authorized and directed to deliver to Lender and at Borrower's
expense, copies of all confirmations and other notices with respect to all
transactions executed by Intermediary for the account of Borrower, copies of the
periodic Account statements of Borrower, and copies of any and all matters
pertaining to the accounts of Borrower with Intermediary, including, without
limitation, copies of all correspondence directed to Borrower.

8.  As between Borrower and Lender, this Agreement shall remain in full force
and effect until canceled in writing by the Lender. Any cancellation of this
agreement shall be without effect as to Intermediary until Intermediary is
notified in writing by Lender.

9.  Borrower hereby represents and warrants to Lender that neither the Account
above assigned, nor any of the investment property therein contained have not
heretofore been alienated or assigned, and that Borrower will not allow any
lien, security interest or encumbrance to attach to such Account (other than the
security interest of Lender) without the written consent of Lender.

10. This Agreement shall be binding upon Borrower, and upon Borrower's 
successors and assigns, including, without limitation, any trustee in 
bankruptcy, and it shall be binding upon and inure to the benefit of the 
successors and assigns of Lender and Intermediary.

11. Borrower agrees to indemnify, defend, save and hold free and harmless
Intermediary from any claim of Borrower, Lender or any third party arising out
of compliance with any instruction or requests of Borrower or Lender with
respect to the Account, or any attempted attachment or garnishment of such
Account, or any property therein contained, including all reasonable fees and
expenses, including without limitation, attorneys' fees.

12. Intermediary owes no duty to Lender to do or refrain from doing any act
other than to follow specific instructions from Lender as authorized by this
Agreement. In all other respects, the operation and management of Borrower's
account will continue unmodified, except as specifically indicated to the
contrary by this Agreement.

TERMS AND CONDITIONS OF LEASE AGREEMENT

1.   TERM AND RENT. Lessor agrees to lease the above described equipment (the
"Equipment") to the Lessee for the term and rental as set forth, payment of the
rental installments to begin on the Date of Acceptance. As long as no event of
default exists, Lessor will not interfere with Lessee's possession, use and
quiet enjoyment of the Equipment.

2.   PURCHASE AND ACCEPTANCE. Lessee requests Lessor to purchase the Equipment
from the Seller and arrange for delivery to Lessee, at Lessee's expense.
Delivery shall be deemed complete upon the Date of Acceptance. LESSOR SHALL NOT
BE LIABLE FOR LOSS OR DAMAGE OR FOR THE DELAY OR FAILURE OF SELLER TO FILL OR
DELIVER THE ORDER FOR THE EQUIPMENT. THE LESSEE REPRESENTS THAT LESSEE HAS
SELECTED THE EQUIPMENT DESCRIBED ABOVE BEFORE HAVING REQUESTED LESSOR TO
PURCHASE SAME FOR LEASING TO LESSEE.

3.   NON-CANCELABLE LEASE. THIS IS A NON-CANCELABLE LEASE. When Lessee signs
and delivers a certificate of acceptance for the Equipment, its obligations to
pay all rent and other amounts when due for the Equipment and otherwise to
perform as required under the lease are unconditional, irrevocable and
independent. These obligations are not subject to cancellation, termination,
modification, repudiation, excuse or substitution by Lessee. Lessee is not
entitled to any abatement, reduction, offset, defense or counterclaim with
respect to these obligations for any reason whatsoever, whether arising out of
default or other claims against Lessor or the manufacturer or supplier of the
Equipment, defects in or damage to the Equipment, its loss or destruction or
otherwise.

4.   DISCLAIMER OF WARRANTIES BY LESSOR; RIGHTS OF LESSEE. LESSOR MAKES NO
WARRANTY, EXPRESS OR IMPLIED, AS TO ANY MATTER WHATSOEVER, INCLUDING THE
CONDITION OF THE EQUIPMENT, ITS MERCHANTABILITY OR ITS FITNESS FOR ANY
PARTICULAR PURPOSE, AND, AS TO LESSOR, LESSEE LEASES THE EQUIPMENT "AS-IS."
UNDER NO CIRCUMSTANCES SHALL LESSOR BE RESPONSIBLE FOR ANY INCIDENTAL OR
CONSEQUENTIAL DAMAGES IN CONNECTION WITH THIS LEASE AND/OR THE EQUIPMENT
THEREUNDER. LESSEE IS ENTITLED TO THE PROMISES AND WARRANTIES, INCLUDING THOSE
OF ANY THIRD PARTY, PROVIDED TO LESSOR BY THE SELLER IN CONNECTION WITH OR AS
PART OF THE CONTRACT BY WHICH LESSOR ACQUIRED THE EQUIPMENT OR THE RIGHT TO
POSSESSION AND USE OF THE EQUIPMENT. LESSEE MAY COMMUNICATE WITH THE SELLER AND
RECEIVE AN ACCURATE AND COMPLETE STATEMENT OF THOSE RIGHTS, PROMISES AND
WARRANTIES, INCLUDING ANY DISCLAIMERS AND LIMITATIONS OF THEM OR OF REMEDIES.

5.   CLAIMS AGAINST SELLER; SELLER NOT AN AGENT OF LESSOR. If the Equipment is
not properly installed, does not operate as represented or warranted by the
Seller or is unsatisfactory for any reason, Lessee shall make any claim on
account thereof solely against the Seller and shall nevertheless pay Lessor all
rent payable under this Lease. Lessor agrees to assign to Lessee, solely for
the purpose of making and prosecuting any such claim, any rights it
- --------------------------------------------------------------------------------

OFFICE. LESSOR AND LESSEE IRREVOCABLY WAIVE ANY AND ALL RIGHTS TO A TRIAL BY
JURY.

may have against the Seller for breach of warranty or representation respecting
the Equipment. Notwithstanding any fees that must be paid to Seller or any
agent of Seller. Lessee understands and agrees that neither the Seller nor any
agent or employee of the Seller is an agent or employee of the Lessor and that
neither the Seller nor its agent or employee is authorized to waive or alter any
term or condition of this Lease.

6.   PAYMENTS. Lessee agrees to pay all Lease payments on the date designated
by Lessor and to pay such other payments and charges as provided in this Lease.
These payments shall be increased by any cost or expense Lessor incurs to
preserve the Equipment or to pay taxes, assessments, fees, penalties, liens or
encumbrances. IF THE COST OF THE EQUIPMENT VARIES FROM THE ESTIMATE UPON WHICH
THIS LEASE IS BASED, LESSEE AUTHORIZES LESSOR TO ADJUST THE LEASE PAYMENTS
PROPORTIONATELY, UPWARD OR DOWNWARD, NOT TO EXCEED TEN PERCENT (10%), TO
COMPENSATE FOR SUCH VARIATION. Each payment will be applied first, at the
Lessor's discretion, to the oldest charge due under the Lease. The acceptance
by Lessor of a smaller sum than due at any time under this Lease shall not
constitute a release or an accord and satisfaction for any greater sum due or to
become due regardless of any endorsement restriction.

7.   TITLE; LOCATION OF THE EQUIPMENT; TERMINATION. Title to the Equipment is
in the Lessor and under no circumstances shall pass to Lessee. The Equipment
shall be kept at Lessee's address indicated on this Lease and shall not be
removed without the written consent of Lessor. At the termination of this Lease
or upon Lessee's default, Lessee, at its own expense, shall assemble and deliver
the Equipment to Lessor at such place as Lessor may designate in writing, in
good order and repair, ordinary wear and tear excepted. Lessee shall give
Lessor 90 days written notice prior to termination that it is returning the
Equipment.

8.   NO ASSIGNMENT BY LESSEE; ASSIGNMENT BY LESSOR. NEITHER THIS LEASE NOR
LESSEE'S RIGHTS SHALL BE ASSIGNED BY THE LESSEE, NOR SHALL ANY OF THE EQUIPMENT
BE SUBLEASED BY THE LESSEE WITHOUT THE WRITTEN CONSENT OF THE LESSOR. Lessor
may at any time sell or assign all or part of its right, title and interest in
and to this Lease and in and to each item of Equipment and monies to become due
to the Lessor hereunder, and Lessor may grant security interests in the
Equipment, subject to the Lessee's rights therein as set forth in this Lease,
and in such events, all the provisions of this Lease for the benefit of Lessor
shall inure to the benefit of and be exercised by or on behalf of such assignee,
but the assignee, shall not be liable for or be required to perform any of
Lessor's obligations to Lessee. All rental payments due and to become due under
this Lease and assigned by Lessor shall be paid directly to assignee, upon
written notice of such assignment to Lessee and the right of the assignee to the
payment of assigned rentals and performance of all Lessee's obligations and to
exercise any other of Lessor's rights hereunder shall not be subject to any
defense, counterclaim or setoff which the Lessee may have or assert against the
Lessor and the Lessee hereby agrees that it will not assert any such defenses,
setoffs, counterclaims and claims against the assignee.

9.   INSURANCE. Lessee shall keep the Equipment insured against loss by fire,
theft and all other hazards (comprehensive coverage) at replacement cost by
insurers and in form, amount and coverage satisfactory to Lessor. Lessee
appoints Lessor as Lessee's attorney in fact to endorse any loss payment or
returned premium check and to make any claim under such insurance. Said
policies shall be endorsed with Lessor as a loss payee and additional insured
and shall contain provisions (a) that such insurance shall not be cancelled
except upon ten days notice to Lessor and (b) that the interest of Lessor shall
not be invalidated by any act of Lessee. The policies of insurance or
endorsement certificates shall be delivered to Lessor within 30 days of the Date
of Acceptance. In the event of loss, destruction or theft of, or damage to, any
of the Equipment, Lessee will immediately notify Lessor.

The loss, destruction, theft of or damage to the Equipment shall not relieve the
Lessee from its obligation to pay the full rentals payable hereunder and
Lessor's remaining residual interest. Any sums collected from insurance for the
total loss of any of the Equipment shall be credited to the final installments
of rent payable hereunder and Lessor's remaining residual interest. If any of
the Equipment is partially damaged, Lessee shall repair such damage at its own
cost and expense and any sums collected on insurance on account of such damage
shall be applied to the cost thereof, but on default of the Lessee in repairing
such damage within 30 days of the occurrence thereof, the sums collected
therefor shall be applied to the last maturing installments of rent payable
hereunder or to the repair of the Equipment at Lessor's sole option.

Lessee shall insure the Lessor and Lessee with respect to liability for personal
injuries, damage to or loss of use of property resulting from the ownership, use
and operation of the Equipment with insurers satisfactory to Lessor in amounts
of at least $500,000 per individual and $1,000,000 per occurrence for personal
injuries and $100,000 for property damage, and deliver the policies or
certificates thereof to Lessor.

If Lessee shall default in obtaining any insurance described above, Lessor may
place such insurance. Any premiums paid by Lessor shall be additional rent
payable on demand with interest at the highest legal rate from the date of
payment. At Lessor's sole option, such amounts together with interest may be
added to the lease balance to be paid by Lessee as additional monthly rental.

10.  REPAIRS; USE; ALTERATIONS. Lessee, at its own expense, shall keep the
Equipment maintained in good repair, condition and working order; shall use the
Equipment lawfully and shall not alter the Equipment without the Lessor's prior
written consent. All items which become attached to or a part of the Equipment
become the property of Lessor.

11.  TAXES. Lessee shall reimburse the Lessor (or pay directly if, but only if
instructed by Lessor) for all charges and taxes (local, state and federal) which
may now or hereafter be imposed or levied upon the Lease, rental, operation,
leasing, sale, ownership, possession or use of the Equipment excluding all taxes
based upon income or gross receipts of Lessor.

12.  DEFAULT. Any of the following shall constitute an event of default by
Lessee: a) Lessee fails to pay when due, any rent or other amount required by
this Lease; b) Lessee breaches any covenant of this Lease or fails to promptly
perform any of its terms or conditions, including but not limited to return of
the Equipment at the expiration of the lease term; c) Lessee makes an assignment
for the benefit of creditors; d) a petition is filed by or against Lessee in
bankruptcy or for the appointment of a receiver; e) dissolution or suspension of
Lessee's usual business; f) Lessee makes a bulk transfer or sale of furniture,
furnishings, fixtures or other equipment or inventory; g) any representation,
warranty, or signature made by Lessee in this Lease or related document is
incorrect, fraudulent or breached; or h) Lessee defaults under the terms of any
agreement or instrument relating to any lease or debt for borrowed money such
that the lessor accelerates the rent or the creditor declares the debt due
before its maturity. Lessee agrees to give Lessor prompt notice upon the
occurrence of a default.

13.  LESSOR'S REMEDIES UPON DEFAULT. If an event of default occurs, Lessee's
right to continue in possession of the Equipment shall immediately cease, and
Lessor shall have the right to execute any one or more of the following
remedies in order to protect its interests and reasonably expected profits and
benefits of bargains with the Lessee: a) cancel this Lease; b) take possession
of the Equipment without liability to Lessee for any damages occasioned by such
taking; c) recover from Lessee, with or without repossessing the Equipment, the
sum of (1) accrued and unpaid rent and other amounts payable as of the date of
default, (2) the present value (as of the date of payment) of the rent for the
remaining term of this Lease agreement at 5% per annum; and (3) the residual
value of the Equipment as measured by its anticipated fair market value as of
the expiration of the lease term; provided, however that upon repossession or
surrender of the Equipment, Lessor shall either sell, lease or otherwise dispose
of the Equipment in a commercially reasonable manner, with or without notice and
on public or private bid, and apply the net proceeds (after deducting all
expenses, including attorneys' fees incurred in connection therewith), to the
sum of (2) and (3) above, or Lessor may retain any repossessed Equipment and
credit its fair market value to the sums of (2) and (3) above; or d) exercise
any other right or remedy available to Lessor at law or in equity.

In the event Lessor assigns its right to receive rentals under this agreement
(but not its residual interest) and in the further event of default by Lessee,
Lessee remains liable to Lessor for Lessor's remaining residual interest in the
Equipment as measured above. This liability of Lessee is unconditional and is
not affected by Lessor's assignee repossessing and/or selling the Equipment to
wholly or partially satisfy assignee's right to receive the assigned rentals.

14.  RENEWAL. If the Equipment is not delivered to Lessor at the termination
hereof in accordance with paragraph 7, then this Lease shall renew from month to
month upon the same terms and conditions, subject to the right of Lessor or
Lessee to terminate the renewed Lease on 30 days written notice, in which event,
the Equipment shall immediately be returned to Lessor.

15.  LATE CHARGES. Without limiting Lessor's remedies above, if Lessee shall
fail to pay any amount of rental or other payment for a period of ten days after
its due date, Lessee agrees to pay Lessor a late charge of 5% of each such
payment or installment, with a minimum late charge of $25.00.

16.  FINANCING STATEMENTS. The Lessor is authorized to file a financing
statement signed only by the Lessor in accordance with the Uniform Commercial
Code or one signed by Lessor, as Lessee's attorney in fact.

17.  FINANCIAL REPORTS. Upon request by Lessor, Lessee will promptly furnish to
Lessor all financial reports deemed necessary by Lessor.

18.  JURISDICTION; VENUE. THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE
STATE OF MICHIGAN. LESSEE CONSENTS TO THE JURISDICTION OF THE COURTS OF
MICHIGAN AND TO VENUE IN THE COURTS OF THE COUNTY OF OAKLAND. NO PROVISION
WHICH MAY BE CONSTRUED AS UNENFORCEABLE SHALL IN ANY WAY INVALIDATE ANY OTHER
PROVISION, ALL OF WHICH SHALL REMAIN IN FULL FORCE AND EFFECT.

19.  WARRANTIES BY LESSEE. Lessee warrants and represents that: (a) the
Equipment is being leased for business purposes; (b) all signatures are genuine;
(c) the person signing the Lease is authorized to do so; (d) if more than one
Lessee named, the liability of each is agreed to be joint and several.

20.  INDEMNITY BY LESSEE. LESSEE AGREES TO INDEMNIFY AND HOLD LESSOR OR ANY
ASSIGNEE HARMLESS FROM ANY AND ALL CLAIMS, ACTIONS, PROCEEDINGS, EXPENSES,
DAMAGES, AND LIABILITIES, INCLUDING ATTORNEYS' FEES, ARISING OUT OF OR IN ANY
MANNER PERTAINING TO THE EQUIPMENT OR THIS LEASE INCLUDING, WITHOUT LIMITATION,
THE OWNERSHIP, SELECTION, POSSESSION, PURCHASE, DELIVERY, INSTALLATION, LEASING,
OPERATION, USE, CONTROL, MAINTENANCE AND RETURN OF THE EQUIPMENT AND THE
RECOVERY OF CLAIMS UNDER INSURANCE POLICIES.

In addition, notwithstanding any other provision of this Lease, if as to any
Equipment the modified accelerated cost recovery system or depreciation
deductions allowed under the Internal Revenue Code of 1986, as amended, (the
"Code") shall be lost, disallowed, eliminated, reduced, recaptured or otherwise
unavailable to Lessor for any reason, then Lessee shall pay to Lessor as
additional rent within 30 days after such a loss an amount which shall be equal
to the sum of (i) the additional federal, state, local and foreign income or any
other taxes payable as a result of such loss, disallowance, elimination,
reduction, recapture or unavailability of accelerated cost recovery or
depreciation deductions plus (ii) the amount of any interest, penalties or
additions to tax payable by the Lessor as a result of such additional tax.

Lessee acknowledges that the Equipment to be leased by Lessor to Lessee pursuant
to this agreement is owned by Lessor ("Owner"). It is the intent of
Owner/Lessor and Lessee that this Lease constitute a true lease for Federal
income tax purposes so that, for the purpose of determining its liability for
Federal income taxes, Owner shall be entitled to the tax benefits as are
provided by the Code to an owner of personal property.

The indemnities given and liabilities assumed by the Lessee pursuant to this
Section 20 shall continue in full force and effect notwithstanding the
expiration or other termination of this Lease.

21.  NOTICES. Notice to a party shall be given by certified mail, return
receipt requested.

22.  LABELS AFFIXED TO EQUIPMENT. Lessor shall have the right, but not the
obligation, to affix or attach ownership identification labels to the Equipment.
Lessee agrees not to remove any such labels.

23.  LESSOR'S EXPENSE. Lessee shall pay Lessor all costs and expenses,
including reasonable attorneys' fees and the fees of any collection agencies,
incurred by Lessor in enforcing any of the terms, conditions, or provisions
hereof or in protecting Lessor's rights herein. These costs and expenses shall
include, without limitation, any costs or expenses incurred by the Lessor in any
bankruptcy, reorganization, insolvency or other similar proceeding.

24.  ENTIRE AGREEMENT. This Lease constitutes the entire agreement of the
parties in connection with the Equipment. Neither party relies on any other
statements, understandings, representations or assurances, the same, if any,
having been merged into this agreement. This agreement cannot be modified
except by a writing signed by each party. This agreement inures to the benefit
of the heirs, executors, administrators, successors and assigns of the parties.
