                                  THE COMPANY
 
     Nanophase Technologies Corporation ("Nanophase" or the "Company") develops
and markets nanocrystalline materials for use as ingredients and components in a
wide range of commercial applications. The Company began manufacturing
nanocrystalline materials in commercial quantities in the fourth quarter of
1996. Nanocrystalline materials are metallic and ceramic materials that
generally consist of particles that are less than 100 nanometers (billionths of
a meter) in diameter and contain only a few thousand or tens of thousands of
atoms, rather than the millions or billions of atoms in particles of most
conventional materials. By processing materials in this near-atomic size range,
the Company is able to engineer the structure of particles and exploit the
properties of their surface atoms to enhance the performance of basic raw
materials such as aluminum, iron, titanium and zinc, as well as to molecularly
engineer new composite materials. Compared to conventional materials, the
Company believes its nanocrystalline materials generally exhibit superior
chemical, mechanical, electronic, magnetic and optical properties. The Company
believes that through its extensive proprietary research and development
programs, combined with its proprietary and patented production processes, it
has established new standards for high-performance commercially produced
nanocrystalline materials.
 
   
     The Company is in the advanced materials industry and has identified
initial commercial applications for its nanocrystalline materials in four
primary markets: electronics, structural ceramics and composites, cosmetics and
skin-care, and industrial catalysts. The Company believes each of these markets
provides numerous commercial applications in which its nanocrystalline materials
will have significant competitive advantages based on product performance.
Commercial applications currently being developed in these markets include the
following:
    
 
     - Electronics. Abrasives for chemical/mechanical polishing of semiconductor
       wafers (CMP), anti-radiation coatings for cathode ray tubes ("CRTs"),
       thin-film materials for semiconductor manufacturing, high-performance
       electrodes and photonic materials for flat-panel displays.
 
     - Structural Ceramics and Composites. Ceramic mechanical seals, components
       for continuous steel casting, abrasion-resistant polymers for oil
       drilling sensors, ceramic armor and remotely monitored medical implants.
 
     - Cosmetics and Skin-Care. Topical health-care products, transparent
       ultraviolet ("UV") blockers and colorants for cosmetics.
 
     - Industrial Catalysts. Chemical-process catalysts.
 
     In each of these markets, the Company's strategy is to establish
collaborative relationships with industry leaders in order to validate the
capabilities of its materials and coordinate the development and commercial
introduction of product applications. These relationships generally include
specific milestones and a development path that is intended to lead to
significant commercial product revenues. The Company is currently collaborating
with, among others, AG Industries ("Acutus Gladwin"), The Dow Chemical Company
("Dow"), E.I. DuPont de Nemours & Co. ("DuPont"), Medtronic, Inc. ("Medtronic"),
Pacific Safety, Inc. ("Pacific Safety") and Philips Electronics N.V.
("Philips"). As a result of its collaborative relationships, the Company entered
into commercial supply contracts with Moyco Technologies, Inc. ("Moyco"), a
manufacturer of semiconductor polishing slurries for use by semiconductor
manufacturers, including Hyundai
                                        3
<PAGE>   5
 
Corporation ("Hyundai"), Samsung Group ("Samsung"), International Business
Machines Corporation ("IBM"), Lucent Technologies, Inc. ("Lucent") and Motorola,
Inc. ("Motorola"); with Schering-Plough Corporation ("Schering-Plough") pursuant
to which the Company will supply its nanocrystalline zinc oxide to
Schering-Plough for use in topical health-care products; and with LWT
Instruments, Inc. ("LWT") for anti-abrasive polymers used in oil drilling
applications. To gain access to foreign markets, Nanophase has entered into an
agreement with a subsidiary of Itochu Corporation ("Itochu"), formerly C. Itoh,
for the distribution of the Company's materials in broad-based industrial
markets throughout Asia. To gain world-wide access to the cosmetics and
skin-care market, the Company has a global distribution agreement with
Whittaker, Clark & Daniels, Inc. ("WCD"), a leading distributor of cosmetic and
skin-care ingredients.
 
     The Company believes that its nanocrystalline materials have broad and
enabling potential beyond the product applications it is currently developing
with its customers. In 1995, the Battelle Memorial Institute, a leading contract
research organization, identified "molecularly engineered" materials (i.e.,
nanocrystalline materials) as "super materials" which represent one of the ten
most important technologies for the coming decade. Nanophase was organized in
1989 to commercialize technologies that are based on principles developed at
Argonne National Laboratory ("Argonne"), and believes that it is the only
company to successfully transition the production of high-performance
nanocrystalline materials from laboratory to commercial scale. In contrast to
particles of conventional materials, including other commercially produced
nanocrystalline materials, the particles of the Company's nanocrystalline
materials are (i) nearly spherical, (ii) virtually free of chemical residues,
(iii) uniformly small, (iv) not strongly agglomerated, and (v) easily
engineered. As a result, the Company is able to engineer the attributes,
including strength, flexibility, color and electronic conductivity, of materials
to yield products that are superior to conventional materials and to establish
new standards for a range of high-performance commercial applications.
 
     At the core of the Company's technologies is its proprietary and patented
physical-vapor-synthesis ("PVS") process, which enables the Company to produce
significant quantities of high-quality nanocrystalline materials. The Company
also has developed related technologies to further enhance the materials
produced by its PVS process. The Company's proprietary
discrete-particle-encapsulation ("DPE") process, which completely coats each
individual nanocrystalline particle and for which a patent is pending, can alter
or enhance the optical, chemical and electronic behavior of particles and
prevent agglomeration. The Company also has developed a proprietary net-shaping
technology which enables the rapid fabrication of dimensionally-precise,
high-tolerance structural ceramic components without costly machining.
 
   
     Nanophase's principal production and research facility is located in Burr
Ridge, Illinois, a suburb of Chicago. The Company's operations in Burr Ridge are
registered under ISO 9001 standards, and the Company believes its manufacturing
operations are compliant with the current Good Manufacturing Practices ("cGMP")
requirements of the U.S. Food and Drug Administration ("FDA").
    
 
   
     Nanophase was incorporated in Illinois on November 30, 1989, and will be
reincorporated in Delaware not later than the effective date of this offering.
As of September 30, 1997, the Company had an accumulated deficit of $13,976,617.
Nanophase's principal executive offices are located at 453 Commerce Street, Burr
Ridge, Illinois 60521 and its telephone number is (630) 323-1200.

LIMITED HISTORY OF COMMERCIAL SALES; UNCERTAIN MARKET ACCEPTANCE OF THE
COMPANY'S NANOCRYSTALLINE MATERIALS
 
     The Company was founded in November 1989 and through December 31, 1996 was
engaged principally in research and development activities. While the Company
recently commenced marketing certain nanocrystalline materials, it is in the
early stage of commercialization and its potential product applications are in
various stages of development or under evaluation. As a result, the Company's
nanocrystalline materials have been sold only in limited quantities, generally
for testing and evaluation purposes, and there can be no assurance that a
significant market will develop for such materials. Because virtually all of the
product applications for the Company's materials are new, in order to penetrate
its targeted markets, the Company must participate in a multi-step process that
includes initial discussions of the product application which highlight the
advantages of the Company's nanocrystalline materials, proof of concept, proof
of feasibility within the specific application, and evaluations of cost and
manufacturability. Completion of this evaluation process usually takes at least
18 months, and may take several years. The Company's current and potential
commercial customers establish demanding specifications for performance and
reliability. Although the products incorporating the Company's nanocrystalline
materials have passed certain product performance and reliability testing by
certain current and potential customers, there can be no assurance that the
Company's nanocrystalline materials will continue to pass such tests in the
future, meet future customer performance standards, or offer sufficient price or
performance advantages as required to achieve commercial success. The Company's
failure to develop, manufacture and commercialize nanocrystalline materials on a
timely and cost-effective basis or successfully complete its customers'
multi-step evaluation processes would have a material adverse effect on the
Company's business, results of operations and financial condition. Because the
Company's materials are used as ingredients in, or components of, other
companies' products, the inability of the Company's customers to achieve market
acceptance with respect to end-users of their products or successfully to
manufacture their products could also have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Business."
 
LIMITED OPERATING HISTORY; HISTORY OF LOSSES; UNCERTAINTY OF FUTURE
PROFITABILITY
 
     Substantially all of the Company's revenues through December 31, 1996 were
derived from government research contracts, commercial development contracts and
sales of nanocrystalline products for customer evaluation. The Company has only
recently begun shipping significant amounts of its materials for commercial use
and there can be no assurance that the Company's nanocrystalline materials will
generate significant revenues from commercial applications. Accordingly, the
Company has only a limited operating history upon which an evaluation of the
Company and its prospects can be based. An investment in the Company must be
considered in light of the risks, expenses and difficulties frequently
encountered by companies in the early stages of development.
 
   
     The Company has incurred net losses in each year since its inception, and
as of September 30, 1997, had an accumulated deficit of $13,976,617. The Company
may continue to incur operating losses and there can be no assurance that the
Company will become profitable. Commercial development of the Company's
nanocrystalline materials will require the commitment of substantial resources
to continuing research and development, establishment of additional
commercial-scale manufacturing facilities, and further development of quality
control, marketing, sales, service and administrative capabilities. The
Company's ability to achieve profitability will depend on many factors,
including the Company's ability to enter into collaborative customer
relationships and the Company's ability, alone or with its customers, to
develop, manufacture, introduce and market commercially acceptable products
based on the Company's nanocrystalline materials and proprietary
    
 
                                        7
<PAGE>   9
 
processes. There can be no assurance that significant quantities of the
Company's nanocrystalline materials or their product applications will be
manufactured, introduced or marketed successfully, or that the Company will ever
achieve a profitable level of operations or, if profitability is achieved, that
it can be sustained. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business."
 
DEPENDENCE ON A LIMITED NUMBER OF KEY CUSTOMERS
 
   
     A limited number of key customers have initially accounted for a
substantial portion of the Company's commercial revenue. The Company's customers
are significantly larger than, and are able to exert a high degree of influence
over, the Company. The loss of one or more of the Company's customers or failure
to attract new customers would have a material adverse effect on the Company's
business, results of operations and financial condition. In February 1997, the
Company entered into a five-year requirements contract with Moyco, one of its
key customers, pursuant to which the Company will supply its nanocrystalline
materials to Moyco for use in Moyco's semiconductor polishing slurries. In
August 1997, Moyco and Ashland Chemical Company ("Ashland") signed a non-binding
letter of intent pertaining to the potential purchase by Ashland of Moyco's
intellectual properties, technologies and certain other intangible assets for
the chemical/ mechanical polishing of semiconductor wafers. There can be no
assurance that Moyco will sell such assets to Ashland or any other entity or if
it does or does not sell such assets what the impact on the Company will be.
Sales to Moyco or Ashland, as the case may be, are currently expected to
constitute a significant portion of the Company's revenues over the next three
years. In March 1997, Cabot Corporation ("Cabot") filed a claim against Moyco
which alleges that the slurries manufactured by Moyco, which contain the
Company's nanocrystalline materials, infringe a patent owned by Cabot. Moyco has
denied Cabot's allegations of patent infringement. In April 1997, Moyco filed a
civil action against Cabot alleging that Cabot's patent is invalid and that
Cabot improperly interfered with contractual relationships between Moyco and
third parties. If Cabot prevails in its patent infringement claim against Moyco
or Moyco is otherwise prevented from manufacturing slurries which contain the
Company's materials, then Moyco's purchase of the Company's materials may be
significantly reduced which would have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Business--Customers and Applications--Electronics--Semiconductor Polishing."
    
 
RELIANCE ON COLLABORATIVE DEVELOPMENT RELATIONSHIPS
 
     The Company has established, and will continue to pursue, collaborative
relationships with a variety of corporate customers. Through such relationships,
the Company seeks to develop applications for the Company's nanocrystalline
materials, share development and manufacturing resources and coordinate the
development, manufacturing, commercialization and marketing of nanocrystalline
product applications. The Company's future success will depend, in part, on its
continued relationships with these customers, its ability to enter into similar
collaborative relationships, the commitment of the Company's customers to the
potential product applications under development and, eventually, the customers'
success in marketing, or willingness to purchase the Company's nanocrystalline
materials for, such product applications. There can be no assurance that the
Company's customers will not seek to manufacture jointly developed products
internally or obtain them from alternative sources. These customers may require
the Company to share control of its development, manufacturing and marketing
programs, limit its ability to license its technology to others, or restrict its
ability to engage in certain product development, manufacturing and marketing
activities. These relationships may also be subject to unilateral termination by
the Company's customers. If the Company is unable to initiate or sustain such
collaborative relationships, there can be no assurance that the Company will be
able independently to develop, manufacture, market or sell its current and
future nanocrystalline materials or their product applications. The failure of
the Company to initiate or sustain such collaborative relationships would have a
material adverse effect on the Company's business, results of operations and
financial condition. See "Business--Customers and Applications."
 
LIMITED MANUFACTURING CAPACITY AND EXPERIENCE
 
     The Company's success will depend, in part, on its ability to manufacture
its nanocrystalline materials in significant quantities, with consistent
quality, at acceptable cost and on a timely basis. The Company has limited
experience in high-volume manufacturing, may incur significant start-up costs
and unforeseen
 
                                        8
<PAGE>   10
 
expenses in connection with attempts to manufacture substantial quantities of
nanocrystalline materials, and will need to increase the efficiency of its
manufacturing operations significantly to reach its production goals. In
addition, the Company will need to expand its current facilities or obtain
additional facilities in the near future in order to manufacture substantial
quantities of its products. No assurance can be given that the Company will be
able to make the transition to high-volume production successfully. The
Company's primary operations, including research, engineering, manufacturing,
marketing, distribution and general administration, are housed in a single
facility in Burr Ridge, Illinois. Any material disruption in the Company's
operations, whether due to fire, natural disaster, power loss or otherwise,
could have a material adverse effect on the Company's business, results of
operations and financial condition. While the Company maintains property and
business interruption insurance, such insurance may not adequately compensate
the Company for all losses that it may incur. See "Business--Manufacturing and
Facilities."
 
     While most of the Company's product applications involve the Company
producing materials which are to be used as ingredients in other companies'
products, the Company's net-shaping applications require the Company to produce
finished components. The Company currently is not capable of producing ceramic
finished components in commercial volume and plans to develop an in-house
capability to fabricate net-shaped components or establish manufacturing
arrangements with third parties. There can be no assurance that the Company will
be able to fabricate its net-shaped components internally or that it will be
able to enter into third-party arrangements on satisfactory terms. See
"Business--Manufacturing and Facilities."
 
DEPENDENCE ON PATENTS AND PROTECTION OF PROPRIETARY INFORMATION
 
     The Company's success will depend, in part, on its ability to obtain patent
protection for its nanocrystalline materials and processes, to preserve its
trade secrets, and to operate without infringing the patent or other proprietary
rights of others and without breaching or otherwise losing rights in the
technology licenses upon which any of the Company's products are based. The
Company has been granted two United States patents which expire in July 2013,
has filed three applications for other United States patents and licenses eleven
patents held by others, which licenses generally last the life of their
respective patents. No assurance can be given that the patent applications filed
by the Company will result in issued patents or that the scope and breadth of
any claims allowed in any patents issued to the Company or its licensors will
exclude competitors or provide competitive advantages to the Company. In
addition, there can be no assurance that any patents issued to the Company or
its licensors will be held valid if subsequently challenged or that others will
not claim rights in the patents and other proprietary technology owned or
licensed by the Company, or that others have not developed or will not develop
similar products or technologies without violating any of the Company's
proprietary rights. The Company's inability to obtain patent protection,
preserve its trade secrets or operate without infringing the proprietary rights
of others, as well as the Company's loss of any license to technology that it
now has or acquires in the future, would have a material adverse effect on the
Company's business, results of operations and financial condition.
 
     Patent applications in the United States are currently maintained in
secrecy until patents issue, and patent applications in foreign countries are
maintained in secrecy for a period of time after filing. Accordingly,
publication of discoveries in the scientific literature or of patents themselves
or laying open of patent applications in foreign countries tends to lag behind
actual discoveries and filings of related patent applications. Due to this
factor and the large number of patents and patent applications related to
nanocrystalline materials, comprehensive patent searches and analysis associated
with nanocrystalline materials are often impractical or not cost-effective.
Therefore, there can be no assurance that the Company's patent and publication
searches have been comprehensive, or that materials or processes used by the
Company for its planned products do not or will not infringe upon existing
technology described in United States patents or will not infringe upon claims
of patent applications of others in the future. Because of the volume of patents
issued and patent applications filed relating to nanocrystalline materials,
there is a significant risk that current and potential competitors and other
third parties have filed or will file patent applications for, or have obtained
or will obtain patents or other proprietary rights relating to, materials or
processes used or proposed to be used by the Company. In any such case, to avoid
an infringement, the Company would have to either license such technology or
design around any such patents. There can be no assurance that the Company will
be able either
 
                                        9
<PAGE>   11
 
to successfully design around these third-party patents or obtain licenses to
such technology or that, if obtainable, such licenses would be available on
terms acceptable to the Company.
 
     Litigation, which could result in substantial cost to, and diversion of
effort by, the Company, may be necessary to enforce patents issued or licensed
to the Company, to defend the Company against infringement claims made by
others, or to determine the ownership, scope or validity of the proprietary
rights of the Company and others. An adverse outcome in any such litigation
could subject the Company to significant liabilities to third parties, require
the Company to seek licenses from third parties, and/or require the Company to
cease using certain technology, any of which could have a material adverse
effect on the Company's business, results of operations and financial condition.
The Company may also become involved in interference proceedings declared by the
United States Patent and Trademark Office ("PTO") in connection with one or more
of the Company's owned or licensed patents or patent applications to determine
priority of invention. Any such proceeding could result in substantial cost to
the Company, as well as a possible adverse decision as to priority of invention
of the patent or patent application involved. In addition, the Company may
become involved in reissue or reexamination proceedings in the PTO in connection
with the scope or validity of the Company's owned or licensed patents. Any such
proceeding could have a material adverse effect on the Company's business,
results of operations and financial condition, and an adverse outcome in such
proceeding could result in a reduction of the scope of the claims of any such
patents or such patents being declared invalid. In addition, from time to time,
to protect its competitive position, the Company may initiate reexamination
proceedings in the PTO with respect to patents owned by others. Such proceedings
could result in substantial cost to, and diversion of effort by, the Company,
and an adverse decision in such proceedings could have a material adverse effect
on the Company's business, results of operations and financial condition.
 
     The Company also relies on trade secrets and proprietary know-how in the
conduct of its business and uses employee and third-party confidentiality and
non-disclosure agreements to protect such trade secrets and know-how. There can
be no assurance that the obligation to maintain the confidentiality of such
trade secrets or proprietary information will not wrongfully be breached by
employees, consultants, advisors or others, that the Company will have adequate
remedies for any breach, or that the Company's trade secrets or proprietary
know-how will not otherwise become known or be independently developed or
discovered by third parties. In addition, because the Company's employees have
not entered into noncompetition agreements with the Company, they may become
competitors of the Company upon termination of employment. See
"Business--Intellectual Property and Proprietary Rights."
 
RAPID TECHNOLOGICAL CHANGE
 
     Rapid changes have occurred, and are likely to continue to occur, in the
development of advanced materials and processes. The future success of the
Company will depend, in large part, upon its ability to keep pace with advanced
materials technologies, industry standards and market trends and to develop and
introduce new and improved products on a timely basis. The Company will require
substantial resources to expand its commercial manufacturing capacity, further
develop its technologies and develop and introduce innovative product
applications. There can be no assurance that the Company's development efforts
will not be rendered obsolete by the research efforts and technological advances
of others or that other advanced materials will not prove more advantageous than
those produced by the Company.
 
LIMITED MARKETING EXPERIENCE; RELIANCE ON DISTRIBUTION AGREEMENTS
 
     The Company has limited experience marketing and selling its products. To
market its nanocrystalline materials directly, the Company will be required to
develop a marketing and sales force that can effectively demonstrate the
advantages of its nanocrystalline product applications compared to competitive
products containing conventional or advanced materials. The Company currently
has arrangements for distribution of certain of its nanocrystalline materials
and expects to enter into additional distribution or other arrangements with
third parties regarding the commercialization or marketing of its materials. The
Company's future success will depend in part on its continued relationships with
distributors, its ability to enter into other similar distribution arrangements,
the continuing interest of the Company's distributors in current and potential
product applications and, eventually, the distributors' success in marketing, or
willingness to purchase, any of the Company's nanocrystalline materials. There
can be no assurance that the Company will be successful in its marketing
efforts, that it will be able to establish adequate sales and distribution
capabilities, that it will be
 
                                       10
<PAGE>   12
 
able to enter into or maintain marketing and distribution arrangements with
third parties on financially acceptable terms, or that any third parties with
whom it enters into such arrangements will be successful in marketing the
Company's products. See "Business--Customers and Applications" and
"--Marketing."
 
COMPETITION
 
     The advanced materials industry is highly competitive. The market for
materials having the characteristics and potential uses of the Company's
nanocrystalline materials is the subject of intensive research and development
efforts by both governmental entities and private enterprises around the world.
The Company believes that the level of competition will increase further as more
product applications with significant commercial potential are developed. The
nanocrystalline product applications being developed by the Company will compete
directly with products incorporating conventional and advanced materials and
technologies. While the Company is not currently aware of the existence of
commercially available competitive products with the same attributes as those
offered by the Company, there can be no assurance that such competitive products
will not be introduced by third parties, or that competing materials based on
different or new technologies may not become commercially available. There can
be no assurance that the Company's competitors will not succeed in developing or
marketing materials, technologies and products that exhibit superior
performance, are more commercially desirable or are more cost effective than
those developed or marketed by the Company. In addition, many potential
competitors of the Company have substantially greater financial and technical
resources, larger research and development staffs, and greater manufacturing and
marketing capabilities than the Company. Failure of the Company's current and
potential nanocrystalline product applications to improve performance
sufficiently at an acceptable price, achieve commercial acceptance or otherwise
compete with conventional materials would have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Business--Competition."
 
FUTURE CAPITAL NEEDS
 
     The Company believes that its future capital requirements will depend, on
many factors, including continued progress in its research and development and
product testing programs, the magnitude of these programs, the costs necessary
to increase the Company's manufacturing capabilities and to market any resulting
materials and product applications, and customer acceptance of the Company's
current and potential materials and product applications. Additional factors
that may affect the Company's future capital requirements are the costs involved
in preparing, filing, prosecuting, maintaining and enforcing patents and other
proprietary rights or in obtaining licenses, the ability of the Company to
establish collaborative relationships, and the amount and timing of future
revenues. Depending on its requirements, the Company may seek additional funding
through public or private financing, collaborative relationships, government
contracts or licensing agreements. There can be no assurance that such
additional financing will be available on acceptable terms or at all. If
adequate funds are not available on acceptable terms, the Company may be
required to delay, scale-back or eliminate manufacturing and marketing of one or
more of its materials or product applications or research and development
programs, or to obtain funds through arrangements with customers or others that
may require the Company to relinquish rights to certain of its technologies or
nanocrystalline materials that the Company would not otherwise relinquish.
Inadequate funding also could impair the Company's ability to compete in the
marketplace. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
RISK OF RESCISSION OF SERIES F OFFERING
 
   
     In June, August and September 1997, the Company issued shares of Series F
Convertible Preferred Stock (the "Series F Preferred") for an aggregate of
$3,876,108 to approximately 60 investors, all of whom are "accredited investors"
within the meaning of rules promulgated under the Securities Act. The offering
and sale of the Series F Preferred was not registered under the Securities Act,
but may not have qualified for an exemption from the registration requirements
of the Securities Act. If the sale of the Series F Preferred was not consummated
in accordance with a valid exemption under the registration requirements of
Section 5 of the Securities Act, purchasers of Series F Preferred may have a
right to rescind their purchases of the Series F Preferred (which will convert
into 748,089 shares of Common Stock upon consummation of this offering) pursuant
to Section 12(a)(1) of the Securities Act, and there may be a risk of
enforcement action by the
    
 
                                       11
<PAGE>   13
 
   
Commission or state securities regulators. Under Section 13 of the Securities
Act, a rescission right, which is the effective equivalent of a put right, can
be maintained to enforce liability under Section 12(a)(1) of the Securities Act
at any time within one year after the violation on which it is based, but in no
event more than three years after the relevant securities were bona fide offered
to the public. A rescission right would entitle the holders of the Series F
Preferred to receive a return of the consideration paid for their shares of
Series F Preferred ($5.18 per share), together with interest from the date of
purchase. The Company does not currently intend to offer rescission to the
holders of the Series F Preferred. Even if the holders of Series F Preferred are
entitled to rescind their purchases, the Company does not believe that any
rescission would adversely affect its financial condition following consummation
of this offering.
    
 
DEPENDENCE ON KEY PERSONNEL
 
   
     The Company's success will depend, in large part, upon its ability to
attract and retain highly qualified research and development, management,
manufacturing and marketing and sales personnel. Due to the specialized nature
of the Company's business, it may be difficult to locate and hire qualified
personnel, and to retain such personnel once hired. The loss of the services of
any of the Company's executive officers or other key personnel, or the failure
of the Company to attract and retain other skilled and experienced personnel on
acceptable terms, could have a material adverse effect on the Company's
business, results of operations and financial condition. The Company does not
have "key-man" life insurance policies covering any of its executive officers or
key employees. See "Management."
    
 
PRODUCT LIABILITY RISKS
 
     The Company may be subject to product liability claims in the event that
any of its nanocrystalline product applications are alleged to be defective or
cause harmful effects. Because the Company's nanocrystalline materials are used
as ingredients in, or components of, other companies' products, to the extent
certain of the Company's customers become subject to claims, suits or complaints
relating to their products, such as medical implants and cosmetic and skin-care
products, there can be no assurance that such claims will not be asserted
against the Company. The Company currently maintains separate insurance coverage
in the amount of $1 million for product liability claims. The cost of defending
or settling product liability claims may be substantial and there can be no
assurance that the Company could do so on acceptable terms or that such claims,
if successful or settled, would not have a material adverse effect on the
Company's business, results of operations and financial condition.
 
INTERNATIONAL SALES
 
   
     For the nine months ended September 30, 1997, 12% of the Company's total
revenues were derived from product sales and development agreements with
international customers, and the Company expects that it will continue to derive
a substantial percentage of revenues from international customers in the future.
There can be no assurance that the Company will be able successfully to market,
sell and deliver its nanocrystalline materials in international markets. In
addition, there are certain risks inherent in conducting international business,
including exposure to currency fluctuations, longer payment cycles, greater
difficulties in accounts receivable collection, political instability,
difficulties in complying with a variety of foreign laws and unexpected changes
in regulatory requirements. There can be no assurance that one or more of such
factors will not have a material adverse effect on the Company's business,
results of operations and financial condition.
    
 
GOVERNMENTAL REGULATIONS
 
     The Company's coating facility, which is located in Chicago, is a "small
quantity generator" of hazardous materials, including ethanol, under the Federal
Resource Conservation and Recovery Act ("RCRA") and, as a result, is subject to
stringent federal, state and local regulations governing the handling, storage
and disposal of such materials. It is possible that current or future laws and
regulations could require the Company to make substantial expenditures for
preventive or remedial action, reduction of chemical exposure or waste treatment
or disposal. There can be no assurance that the Company's operations, business
or assets will not be materially and adversely affected by the interpretation
and enforcement of current or future environmental laws and regulations. The
Company believes it has complied in all material respects with regard to
environmental regulations applicable to it and does not anticipate generating
substantially increased amounts of such
 
                                       12
<PAGE>   14
 
   
materials because its coating process has been modified to significantly reduce
the generation of ethanol. In addition, although management believes that its
safety procedures for handling and disposing of such materials comply with the
standards prescribed by state and federal regulations, the Company's coating
operations do pose a risk of accidental contamination or injury. To date, the
Company has not been required to make substantial expenditures for preventive or
remedial action with respect to the hazardous materials it generates. The
damages in the event of an accident or the costs of such preventive or remedial
actions could exceed the Company's resources or otherwise have a material
adverse effect on the Company's business, results of operations and financial
condition.
    
 
     In addition, both of the Company's facilities and all of its operations are
subject to the plant and laboratory safety requirements of various occupational
safety and health laws. The Company believes it has complied in all material
respects with regard to governmental regulations applicable to it. There can be
no assurance, however, that the Company will continue to comply with applicable
government regulations or that such regulations will not materially restrict or
impede the Company's operations in the future.
 
     The manufacture and use of certain products which contain the Company's
nanocrystalline materials are subject to governmental regulation. As a result,
the Company is required to adhere to the cGMP requirements of the FDA and
similar regulations in other countries which include testing, control and
documentation requirements enforced by periodic inspections. Such regulations
can increase the Company's cost of doing business and/or render certain
potential markets prohibitively expensive. See "Business--Governmental
Regulations."
 
QUARTERLY FLUCTUATIONS IN OPERATING RESULTS
 
     The Company has experienced, and expects to continue to experience,
quarterly fluctuations in its results of operations as a result of a variety of
factors, including the timing and amount of expenses associated with expansion
of the Company's operations, the timing of collaborative relationships with, and
performance of, customers, the timing of new product application offerings,
changes in the Company's revenue mix among its product application offerings,
and changes in the mix between pilot production of new nanocrystalline materials
and full-scale manufacturing of existing nanocrystalline materials. The Company
does not currently have any significant backlog of orders and the timing of
revenues will therefore depend upon the amount and timing of new orders received
for its nanocrystalline materials.
 
   
SIGNIFICANT UNALLOCATED NET PROCEEDS
    
 
   
     A significant portion of the anticipated net proceeds of this offering has
been designated for general corporate purposes rather than specific uses.
Therefore, the Company's management and Board of Directors will have broad
discretion with respect to the use of a significant portion of the net proceeds
of this offering. See "Use of Proceeds."
    
 
NO PRIOR PUBLIC MARKET FOR COMMON STOCK; DETERMINATION OF OFFERING PRICE;
POSSIBLE VOLATILITY OF COMMON STOCK PRICE
 
     Prior to this offering, there has been no public market for the Common
Stock and there can be no assurance that an active trading market will develop
or be sustained after this offering. The initial public offering price for the
Common Stock will be determined by negotiations between the Company and the
Underwriters based upon several factors and may not be indicative of the price
that may prevail in the public market. The stock market has from time to time
experienced significant price and volume fluctuations that may be unrelated to
the operating performance of any particular company. In particular, there has
been significant volatility in the market price of securities of other
technology companies, particularly those that, like the Company, are still
primarily engaged in product development activities. Factors such as
announcements of technology innovations and new product applications by the
Company or its competitors, disputes relating to patents and proprietary rights,
changes in financial estimates by securities analysts, failure to meet earnings
expectations of the market or of analysts, general market conditions and
fluctuations in quarterly operating results may have a significant impact on the
market price of the Common Stock. In the past, following periods of volatility
in the market price of a company's securities, securities class action
litigation has often been instituted against such a company. Any such litigation
initiated against the Company could result
 
                                       13
<PAGE>   15
 
in substantial costs and a diversion of management's attention and resources,
which could have a material adverse effect on the Company's business, results of
operations and financial condition. See "Underwriting."
 
ANTI-TAKEOVER PROVISIONS
 
   
     Upon consummation of this offering, the Company's Board of Directors will
have the authority to issue up to 17,000,000 shares of undesignated preferred
stock and to determine the price, rights, preferences, privileges and
restrictions, including voting rights, of those shares without any further vote
or action by the Company's stockholders. The rights of the holders of Common
Stock will be subject to, and may be adversely affected by, the rights of the
holders of any preferred stock that may be issued in the future. The issuance of
preferred stock, while providing desirable flexibility in connection with
possible financings, acquisitions and other corporate purposes, could have the
effect of making it more difficult for a third party to acquire a majority of
the outstanding voting stock of the Company. The Company has no present plans to
issue such shares of preferred stock. Further, certain provisions of the
Company's Certificate of Incorporation and Bylaws and of Delaware law could
delay or make more difficult a merger, tender offer or proxy contest involving
the Company. See "Description of Capital Stock--Preferred Stock" and "--Certain
Corporate Provisions."
    
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon consummation of this offering, the Company will have a total of
13,234,029 shares of Common Stock outstanding (13,984,029 if the Underwriters
exercise in full their over-allotment option), of which the 5,000,000 (5,750,000
if the Underwriters exercise in full their over-allotment option) shares offered
hereby will be eligible for immediate sale in the public market without
restriction unless they are held by "affiliates" of the Company within the
meaning of Rule 144 ("Rule 144") under the Securities Act of 1933, as amended
(the "Securities Act"), in which case they will be subject to the volume and
other limitations of such rule. The sale of a substantial number of shares of
Common Stock, or the perception that such sales could occur, could adversely
affect prevailing market prices for the Common Stock. The remaining 8,234,029
shares of Common Stock outstanding upon completion of this offering will be
"restricted securities" within the meaning of Rule 144 (the "Restricted Shares")
and all of such Restricted Shares are subject to the lock-up provisions of stock
purchase agreements entered into with the Company pursuant to which the holders
of such Restricted Shares have agreed that they will not, directly or
indirectly, sell or otherwise dispose of any shares of Common Stock for a period
of 180 days after the date of this Prospectus without the prior written consent
of Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ"). Upon expiration
of the lock-up provisions of the stock purchase agreements (or earlier upon the
consent of DLJ), 7,485,940 of the Restricted Shares outstanding upon completion
of this offering will be eligible for sale under Rule 144, subject to, in some
cases, the volume and other limitations of such rule. An additional 662,287
Restricted Shares are issuable upon exercise of currently exercisable warrants
issued to certain of the Company's existing stockholders and an additional
1,557,684 Restricted Shares are issuable at various dates upon exercise of
options heretofore granted to certain employees, consultants and members of the
Advisory Board of the Company pursuant to stock option agreements.
Optionholders, upon the exercise of such options, must enter into agreements
with the Company pursuant to which they will also agree not to sell, offer for
sale or otherwise dispose of any shares of Common Stock for a period of 180 days
after the date of this Prospectus without the prior written consent of DLJ.
    
 
     Subject to the lock-up provisions of the stock-purchase agreements, the
holders of all of the Restricted Shares that will be outstanding upon
consummation of this offering and all of the Restricted Shares issuable upon
exercise of the warrants have been accorded registration rights under the
Securities Act. No prediction can be made as to the effect, if any, that future
sales of shares, or the availability of shares for future sales, will have on
the market price of the Common Stock from time to time or the Company's ability
to raise capital through an offering of its equity securities. See "Description
of Capital Stock--Registration Rights," "Shares Eligible for Future Sale" and
"Underwriting."
 
DILUTION AND DIVIDEND POLICY
 
     The initial public offering price of the Common Stock offered hereby is
substantially higher than the net book value of the currently outstanding Common
Stock. Therefore, purchasers of the Common Stock offered hereby will experience
immediate and substantial dilution in the net tangible book value of the Common
Stock. The Company has never paid a cash dividend on its Common Stock and does
not expect to pay dividends in the foreseeable future. See "Dilution" and
"Dividend Policy."

<PAGE>   16
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the shares of Common Stock
being offered hereby, at an assumed initial public offering price of $10.00 per
share, are estimated to be approximately $46,100,000 ($53,075,000 if the
Underwriters' over-allotment option is exercised in full), after deducting
estimated underwriting discounts and commissions and offering expenses payable
by the Company.
    
 
   
     The Company currently intends to use approximately $35 to $40 million of
the net proceeds for the expansion of its manufacturing facilities over the next
24 months, including approximately $31 to $35 million for installing additional
PVS plasma reactors and making leasehold improvements and approximately $4 to $5
million for purchasing additional equipment. The remaining net proceeds will be
used for working capital and other general corporate purposes. The Company may
from time to time seek to acquire complementary businesses, products, services
or technologies. The Company may use a portion of the net proceeds for one or
more of such transactions, although the Company has no current plans or
agreements with respect to any such transaction. The exact cost, timing and
amount of funds required for specific uses by the Company cannot be precisely
determined at this time. The Company could also potentially use a portion of the
net proceeds to fund a rescission of shares of Series F Preferred. See "Risk
Factors--Risk of Rescission of Series F Offering" and "--Significant Unallocated
Net Proceeds." Pending such uses, the Company intends to invest the net proceeds
of this offering in short-term, investment grade, interest-bearing obligations.
    
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid any cash dividends on its Common
Stock and does not anticipate paying cash dividends or other distributions on
its Common Stock in the foreseeable future, but intends instead to retain any
future earnings for reinvestment in its business. Any future determination to
pay cash dividends will be at the discretion of the Company's Board of Directors
and will be dependent upon the Company's financial condition, results of
operations, capital requirements and such other factors as the Company's Board
of Directors deems relevant.

                                    DILUTION
 
   
     The pro forma net tangible book value of the Company as of September 30,
1997 was $5,352,020 or $0.65 per share of Common Stock. Pro forma net tangible
book value per share represents the amount of total tangible assets of the
Company reduced by the amount of its total liabilities and divided by the total
number of shares of Common Stock outstanding after the Preferred Stock
Conversion. After giving effect to the sale of the 5,000,000 shares of Common
Stock being offered by the Company at an assumed initial public offering price
of $10.00 per share, and after deducting estimated underwriting discounts and
commissions and offering expenses payable by the Company, the pro forma net
tangible book value of the Company as of September 30, 1997 would have been
approximately $51,577,693, or $3.90 per share of Common Stock. This represents
an immediate increase in pro forma net tangible book value of $3.25 per share to
existing stockholders and an immediate dilution of $6.10 per share to new
investors. The following table illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
the Selected Financial Data and financial statements and related notes thereto
appearing elsewhere in this Prospectus. When used in the following discussions,
the words "believes," "anticipates," "intends," "expects" and similar
expressions are intended to identify forward-looking statements. Such statements
are subject to certain risks and uncertainties, including, but not limited to,
those set forth in "Risk Factors," which could cause actual results to differ
materially from those projected.
 
OVERVIEW
 
   
     From its inception in November 1989 through December 31, 1996, Nanophase
was in the development stage. During that period, the Company primarily focused
on the development of its manufacturing processes in order to transition from
laboratory-scale to commercial-scale production. As a result, the Company
developed an operating capacity to produce significant quantities of its
nanocrystalline materials for commercial sale. The Company was also engaged in
developing commercial applications and formulations and recruiting marketing,
technical and administrative personnel. From inception through September 30,
1997, the Company was primarily capitalized through the private placement of
approximately $19,554,000 of equity securities, net of issuance costs.
    
 
     Through 1995, the majority of the Company's revenues resulted from
government contracts to perform research and development activities. During that
period, the Company also entered into cost-sharing agreements with the U.S.
government and offset amounts received against the related costs. During 1996,
the Company began emerging from the development stage and significantly
increased its commercial revenue. Commercial revenue is recorded when products
are shipped by the Company or when specific milestones are met regarding
development arrangements. Cost of revenue generally includes costs associated
with commercial production and customer development agreements, and costs of
material production and development related to government research contracts. In
1996, the Company also began to scale-up operations in its Burr Ridge
manufacturing facility. The Company incurred substantial operating expenses as a
result of certain one-time costs associated with the scale-up of operations.
 
     Since January 1, 1997, the Company has been engaged in commercial
production and sales of its nanocrystalline materials, and the Company no longer
considers itself in the development stage.
 
RESULTS OF OPERATIONS
 
   
  NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1996
    
 
   
     Total revenue increased to $2,245,415 for the nine months ended September
30, 1997, compared to $287,220 for the same period in 1996. Commercial revenue
increased to $2,245,415 for the nine months ended September 30, 1997, compared
to $261,013 for the same period in 1996. This increase in commercial revenue was
due primarily to increased product sales volume, increased acceptance of the
commercial potential of the Company's products, customer development agreements
and a one-time fee of $160,000 paid by the Company's Asian distributor for
training such distributor how to operate a PVS plasma reactor in order to
manufacture samples of the Company's nanocrystalline materials. Revenue from
government research contracts decreased to zero for the nine months ended
September 30, 1997, compared to $26,207 for the same period in 1996, because the
Company did not pursue any further U.S. government contracts for such nine month
period. Cost of revenue as a percentage of revenue decreased significantly for
the nine months ended September 30, 1997, compared to the same period in 1996
primarily because of increased efficiencies in the Company's manufacturing
process and greater production volume.
    
 
   
     Cost of revenue increased to $3,321,288 for the nine months ended September
30, 1997, compared to $2,925,560 for the same period in 1996. This increase in
cost of revenue was generally attributed to a further expansion of the
production infrastructure to support anticipated revenue growth and increased
costs which
    
 
                                       19
<PAGE>   21
 
are commensurate with the increased sales volume and customer development
programs. The Company also incurred development costs to expand its quality
assurance programs and obtain its ISO certification.
 
   
     Research and development expense consists of costs associated with the
Company's development of new product applications and coating formulations and
the cost of enhancing the Company's manufacturing processes. Research and
development expense increased to $571,210 for the nine months ended September
30, 1997, compared to $515,675 for the same period in 1996. The increase in
research and development expense was attributable primarily to the costs of
developing new coating formulations and product applications, increased usage of
research supplies, and ongoing experimentation expenses associated with
technological enhancements and product improvements. The Company expects to
increase its research and development expenditures during the remainder of 1997
in connection with its plans to continue to enhance and expand its product lines
and manufacturing processes.
    
 
   
     Selling, general and administrative expense increased to $1,714,725 for the
nine months ended September 30, 1997, compared to $1,209,823 for the same period
in 1996. This increase was attributable primarily to increased selling and
advertising expense, outside consulting fees, corporate salaries and expensing
costs aggregating $375,103 related to a proposed public offering withdrawn in
May 1997. Selling, general and administrative expense for the third quarter of
1997 also includes certain one-time costs associated with the Company's Asian
distribution agreement. Selling, general and administrative expense is expected
to increase significantly in the next several years to support the Company's
business development efforts.
    
 
   
     Interest income decreased to $57,392 for the nine months ended September
30, 1997, compared to $145,746 for the same period in 1996. This decrease was
primarily due to a lower outstanding cash balance.
    
 
  YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
 
     Total revenue increased to $595,806 in 1996, compared to $121,586 in 1995
and $95,159 in 1994. Commercial revenue increased to $485,036 in 1996, compared
to $93,591 in 1995 and $31,144 in 1994. This increase in commercial revenue was
due primarily to increased commercial acceptance and availability of the
Company's products. Revenue from government research contracts increased to
$110,770 in 1996, compared to $27,995 in 1995 and $64,015 in 1994, as the
Company completed certain development agreements with U.S. governmental
agencies.
 
     Cost of revenue increased to $4,019,484 in 1996, compared to $532,124 in
1995 and $164,746 in 1994. The increase in cost of revenue for 1996 was
generally a result of the scale-up of the Company's operations in anticipation
of increased commercial sales and development. Specifically, the Company
increased expenditures relating to product and process improvement activities.
The Company also incurred one-time costs in connection with the establishment of
its Chicago coating facility, extensive product development activities, the
scale-up of manufacturing operations, and the certification of its Burr Ridge
facility under ISO standards.
 
     Research and development expense increased to $677,284 in 1996, compared to
$485,059 in 1995 and $456,162 in 1994. The increase in research and development
expense was attributable primarily to the hiring of additional research and
development personnel, costs associated with the development and evaluation of
new product applications, and increased purchases and use of research supplies.
 
     Selling, general and administrative expense increased to $1,661,504 in
1996, compared to $1,150,853 in 1995 and $799,558 in 1994. This increase was
attributable primarily to the hiring of additional marketing and administrative
personnel, an increase in selling expenses, and the increase in costs associated
with the establishment of the Company's corporate headquarters.
 
     Interest income was $184,778 in 1996, compared to $86,576 in 1995 and
$37,535 in 1994. The increases resulted from the Company's investment of net
proceeds from its sales of equity securities pending use of such proceeds for
the Company's operations.

LIQUIDITY AND CAPITAL RESOURCES
 
   
     The Company's cash and cash equivalents were $770,704 at September 30,
1997, compared to $617,204 at December 31, 1996 and $261,902 at December 31,
1995. The Company's net cash used in operating activities was $2,740,641 for the
nine months ended September 30, 1997, compared to $4,399,928 for the same period
in 1996. The net cash used in operating activities for the nine months ended
September 30, 1997 was primarily for the further expansion of the production
infrastructure to support anticipated growth, the further development of
products, the funding of research and development activities, and the funding of
trade accounts receivable and inventory levels, which was offset by an increase
in accounts payable and accrued liabilities. Net cash used in investing
activities, including capital expenditures and purchases and sales of securities
in which cash is invested pending its use for the Company's operations, amounted
to $751,068 for the nine months ended September 30, 1997, compared to net cash
used of $2,894,150 for the same period in 1996. Capital expenditures amounted to
$763,276 for the nine months ended September 30, 1997, compared to $1,084,697
for the same period in 1996 and were primarily for leasehold improvements and
equipment purchases. Net cash provided by private placements of equity
securities was $3,770,882 during the nine month period ended September 30, 1997,
compared to $7,182,088 during the same period for the prior year.
    
 
     The Company's net cash used in operating activities was $5,795,858 in 1996,
compared to $1,860,353 in 1995 and $1,206,497 in 1994. The net cash used in 1996
operating activities was primarily for the scale-up of manufacturing operations,
for development of products, and to fund research and development expenses. Net
cash used in investing activities, including capital expenditures and purchases
and sales of securities in which cash is invested pending its use for the
Company's operations, amounted to $951,806 in 1996, $905,615 in 1995 and
$2,396,125 in 1994. Capital expenditures amounted to $1,173,437 in 1996,
$937,956 in 1995 and $66,303 in 1994 and were primarily for leasehold
improvements and equipment purchases. Net cash provided by private placements of
equity securities was $7,182,088 in 1996, compared to $3,009,408 in 1995 and
$3,395,854 in 1994.
 
     The Company believes that funds from operations and cash on hand, together
with the net proceeds of this offering, will be adequate to fund the Company's
current operating plans for the foreseeable future. The Company expects capital
expenditures of approximately $2 million in 1997 and approximately $20 million
to $25 million in 1998, which expenditures will be funded in part by the net
proceeds from this offering. The Company's actual future capital requirements
will depend, however, on many factors, including continued progress in its
research and development and product testing programs, the magnitude of these
programs, the costs necessary to increase the Company's manufacturing
capabilities and to market any resulting materials and product applications, and
customer acceptance of the Company's current and potential materials and product
applications. In addition, the Company could potentially be required to fund a
rescission of shares of Series F Preferred. Depending on future requirements,
the Company may seek additional funding through public or private financing,
collaborative relationships, government contracts or licensing agreements. There
can be no assurance that such additional financing will be available on
acceptable terms or at all, and any such additional financing could be dilutive
to the Company's stockholders. See "Use of Proceeds," "Risk Factors--Future
Capital Needs" and "--Risk of Rescission of Series F Offering."
 
   
     At September 30, 1997, the Company had a net operating loss carryforward of
approximately $13.9 million for income tax purposes. Because the Company may
have experienced "ownership changes" within the meaning of the U.S. Internal
Revenue Code (the "Internal Revenue Code") related to prior issuance of its
preferred stock and may experience ownership changes due to this offering,
future utilization of this carryforward may be subject to certain limitations as
defined by the Internal Revenue Code. If not utilized, the carryforward expires
at various dates between 2005 and 2012. As a result of the annual limitation, a
portion of this carryforward may expire before ultimately becoming available to
reduce income tax liabilities.

                                    BUSINESS
 
     Nanophase develops and markets nanocrystalline materials for use as
ingredients and components in a wide range of commercial applications. The
Company began manufacturing nanocrystalline materials in commercial quantities
in the fourth quarter of 1996. Nanocrystalline materials are metallic and
ceramic materials that generally consist of particles that are less than 100
nanometers (billionths of a meter) in diameter and contain only a few thousand
or tens of thousands of atoms, rather than the millions or billions of atoms in
particles of most conventional materials. By processing materials in this
near-atomic size range, the Company is able to engineer the structure of
particles and exploit the properties of their surface atoms to enhance the
performance of basic raw materials such as aluminum, iron, titanium and zinc, as
well as to molecularly engineer new composite materials. Compared to
conventional materials, the Company believes its nanocrystalline materials
generally exhibit superior chemical, mechanical, electronic, magnetic and
optical properties. The Company believes that through its extensive proprietary
research and development programs, combined with its proprietary and patented
production processes, it has established new standards for high-performance
commercially produced nanocrystalline materials.
 
   
     The Company is in the advanced materials industry and has identified
initial commercial applications for its nanocrystalline materials in four
primary markets: electronics, structural ceramics and composites, cosmetics and
skin-care, and industrial catalysts. The Company believes each of these markets
provides numerous commercial applications in which its nanocrystalline materials
will have significant competitive advantages based on product performance.
Commercial applications currently being developed in these markets include the
following:
    
 
     - Electronics. Abrasives for chemical/mechanical polishing of semiconductor
       wafers (CMP), anti-radiation coatings for CRTs, thin-film materials for
       semiconductor manufacturing, high-performance electrodes and photonic
       materials for flat-panel displays.
 
     - Structural Ceramics and Composites. Ceramic mechanical seals, components
       for continuous steel casting, abrasion-resistant polymers for oil
       drilling sensors, ceramic armor and remotely monitored medical implants.
 
     - Cosmetics and Skin-Care. Topical health-care products, transparent UV
       blockers and colorants for cosmetics.
 
     - Industrial Catalysts. Chemical-process catalysts.
 
     In each of these markets, the Company's strategy is to establish
collaborative relationships with industry leaders in order to validate the
capabilities of its materials and coordinate the development and commercial
introduction of product applications. These relationships generally include
specific milestones and a development path that is intended to lead to
significant commercial product revenues. The Company is currently collaborating
with, among others, Acutus Gladwin, Dow, DuPont, Medtronic, Pacific Safety and
Philips. As a result of its collaborative relationships, the Company entered
into commercial supply contracts with Moyco, a manufacturer of semiconductor
polishing slurries for use by semiconductor manufacturers, including Hyundai,
Samsung, IBM, Lucent and Motorola; with Schering-Plough pursuant to which the
Company will supply its nanocrystalline zinc oxide to Schering-Plough for use in
topical health-care products; and with LWT for anti-abrasive polymers used in
oil drilling applications. To gain access to foreign markets, Nanophase has
entered into an agreement with a subsidiary of Itochu, formerly C. Itoh, for the
distribution of the Company's materials in broad-based industrial markets
throughout Asia. To gain world-wide access to the cosmetics and skin-care
market, the Company has a global distribution agreement with WCD, a leading
distributor of cosmetic and skin-care ingredients.
 
     The Company believes that its nanocrystalline materials have broad and
enabling potential beyond the product applications it is currently developing
with its customers. In 1995, the Battelle Memorial Institute, a leading contract
research organization, identified "molecularly engineered" materials (i.e.,
nanocrystalline materials) as "super materials" which represent one of the ten
most important technologies for the coming decade. Nanophase was organized in
1989 to commercialize technologies that are based on principles developed at
Argonne National Laboratories, and believes that it is the only company to
successfully transition
 
                                       23

the production of high-performance nanocrystalline materials from laboratory to
commercial scale. In 1995, the Company's patented PVS process for producing
these materials received the R&D 100 Award, given each year by R&D Magazine to
recognize the 100 most technologically significant new products and processes in
the world.
 
NANOCRYSTALLINE MATERIALS
 
     All matter is composed of atoms, or molecules which are combinations of
atoms. Most solid materials, such as ceramics and metals, are crystalline in
nature, i.e., they consist of microscopic particles, or crystals, the atoms or
molecules of which are stacked in orderly patterns. The attributes of a
crystalline material, including strength, flexibility, color and electronic
conductivity, depend upon the shape and size of the material's individual
crystals, the organization of atoms in the individual crystals, and the
relationships and interactions among the crystals. The particles of conventional
crystalline materials generally have irregular shapes and sizes. The
organization of a crystalline material's atoms or molecules, however, can be
manipulated to form particles that are much smaller and more uniform. Particles
that are less than 100 nanometers (billionths of a meter) in diameter are
generally called nanocrystals and contain only a few thousand or tens of
thousands of atoms, rather than the millions or billions of atoms in particles
of most conventional materials. Through molecular engineering, the shape and
size of such particles in nanocrystalline materials can be manipulated to
produce materials with superior properties. These nanocrystalline materials
behave in enhanced and novel ways because the properties of, and interactions
among, their ultra-small particles have been significantly altered.
 
     The potential of nanocrystalline materials has been known for decades and
such materials have been produced by a variety of other processes. However,
these other processes are more limited in their ability to engineer the
materials for high-performance applications. Mechanical and chemical processes
are the two most common methods for producing nanocrystalline materials. In
mechanical processes, fine powders are commonly made from large particles
through the use of crushing techniques such as a high-speed ball mill. The
resulting fragmented powders contain particles of inconsistent shapes and sizes,
are relatively coarse, and are not adequate for many high-performance commercial
applications. Nanocrystalline materials can also be made through chemical
processes which utilize chemicals to create a reaction that precipitates
particles of varying size and shape. Chemical processes, like mechanical
processes, often produce nanometric particles of inconsistent shapes and sizes
that are difficult to engineer for high-performance applications. Chemical
processes also tend to leave chemical residues on the particle surfaces, making
it difficult to precisely engineer the mechanical, chemical and electronic
properties of the materials. Historically, high-quality nanocrystalline
materials have been difficult to consistently produce in other than
laboratory-scale quantities and have not been produced at commercially
affordable costs. The Company believes that these traditional methods of
producing nanocrystalline materials do not provide the means to realize the full
potential of such nanocrystalline materials.
 
ADVANTAGES OF THE COMPANY'S NANOCRYSTALLINE MATERIALS
 
     The Company has developed new technologies for the engineering and
high-volume production of high-quality nanocrystalline materials which it
believes cannot be accomplished by the traditional methods described above. At
the core of the Company's technologies is its patented PVS process, whereby
metallic or ceramic materials are vaporized into atoms that are mixed with a gas
to form nanometric particles.
 
     The following attributes of the particles produced by the Company's PVS
process enable it to produce significant quantities of nanocrystalline materials
which it believes to be superior, for a range of high-performance applications,
to both conventional materials and nanocrystalline materials produced by other
means:
 
          SPHERICAL SHAPES AND SMALL SIZES enable particles to slide over each
     other, which allows the Company's ceramic materials to become more ductile
     and more easily formed. This enables the Company to rapidly mold variously
     shaped ceramic components without the costly and time-consuming
 
                                       24
<PAGE>   26
 
     machining which is typically used for conventional ceramics (e.g., 15 to 30
     minutes for the Company's process as opposed to 4 to 8 hours for
     conventional machining).
 
          CLEAN SURFACES enable particles to flow freely and be dispersed
     easily. For example, the Company produces iron oxides that make cosmetics
     feel smoother on the skin and blend easily.
 
          NARROW SIZE DISTRIBUTION of nanometric particles ensures that
     nanocrystalline materials are virtually free of large particles, which
     facilitates engineering of the chemical, mechanical, optical and electronic
     properties of the material because these properties vary according to
     particle size. For example, the Company produces titanium dioxide with
     particles that are large enough to block ultraviolet rays but are
     consistently smaller than the wave length of visible light, which enables
     sunscreens formulated with these particles to provide an unprecedented
     combination of high SPF protection and transparency.
 
          AGGREGATION CONTROL results in loosely agglomerated and uniformly
     small particles that can be readily and uniformly dispersed in a variety of
     media. For example, the Company produces ultra-fine abrasives for slurries
     used to polish the surfaces of semiconductors, which results in
     significantly smoother surfaces and faster and more selective removal of
     material.
 
          DIALABLE CONTROL OF PARTICLE SIZE enables precise engineering of
     particles through subtle modifications of the Company's PVS process. By
     controlling the evaporation rate of a material's atoms or the type or
     pressure of gas used in the production process, the Company can alter,
     enhance and tailor the performance of its basic raw materials for specific
     product applications. For example, further decreasing the particle size of
     a metal oxide increases its number of surface atoms, which enables the
     Company to produce metal oxides with enhanced catalytic performance.
 
     The Company has developed related technologies to further enhance the
materials produced by its PVS process. Because the PVS process produces
particles that, in contrast to particles of conventional materials, are (i)
nearly spherical, (ii) virtually free of chemical residues, (iii) uniformly
small, (iv) not strongly agglomerated, and (v) easily engineered, the Company
can apply its other proprietary technologies to further process these particles
to set new standards for a range of additional high-performance commercial
applications. For example, certain product applications require surface
treatments for nanocrystalline particles so they can be dispersed in a variety
of media. To enable the incorporation of its materials in dispersions, the
Company developed its proprietary DPE process which prevents particles from
agglomerating by completely coating each individual particle. The coating
process also enables the Company to alter the optical, chemical and electronic
behavior of particles to meet the requirements of particular applications. In
addition, certain product applications require nanocrystalline materials to be
formed into structural ceramics of a precise shape and tolerance. As part of its
strategy to enter markets for structural ceramics, the Company developed its
net-shaping technology which enables the rapid fabrication of
dimensionally-precise, high tolerance structural ceramic components without
costly machining.
 
COMPANY STRATEGY
 
     To take advantage of the broad potential applicability of nanocrystalline
materials, the Company has adopted a strategy to develop a variety of
value-added applications in targeted industries where the potential for future
growth is substantial. The Company intends to establish itself as the leading
manufacturer of nanocrystalline materials for these targeted application areas
by continuously enhancing its technologies, product applications and customer
base. Specific elements of the Company's business strategy include the
following:
 
  Target Innovative Commercial Applications
 
     The Company identifies and pursues commercial applications where the
value-added benefits of its nanocrystalline materials and technologies (i)
represent breakthrough capabilities, (ii) are substantial and demonstrable,
(iii) are not achievable with conventional materials, and (iv) offer the Company
the potential for long-term market leadership and sustainable revenues.
 
                                       25
<PAGE>   27
 
  Establish Collaborative Relationships with Marquee Customers
 
     To facilitate the development of product applications that meet market
needs and create markets for its nanocrystalline materials, the Company
establishes collaborative relationships with customers who are leaders in their
industries. The Company targets such customers because it believes that these
customers (i) are technologically innovative, (ii) will support product
development and (iii) require a long-term supply of superior products in order
to maintain their competitive advantages. The collaborative relationships
pursued by the Company include agreed-upon developmental milestones and a
development path that is intended to lead to significant commercial revenues
from the customer.
 
  Expand Product Applications and Broaden the Customer Base
 
     After developing nanocrystalline materials and product applications for a
customer, the Company seeks to broaden its relationship with that customer by
identifying additional opportunities for the Company's nanocrystalline materials
and technologies, and seeks to identify other potential customers in that market
that can benefit from derivative materials and technologies. The Company also
seeks to have the nanocrystalline materials and technologies that it
successfully develops for customers in one market meet the application
requirements of customers in other markets without significant process or
material re-engineering.
 
  Maintain Technical and Commercial Leadership
 
     The Company is committed to maintaining its status as a leader in the field
of nanocrystalline-based materials through ongoing research and development
activities, collaborations with industrial, university and government entities,
and efforts to continuously attract top scientists and engineers. The Company
concentrates its research and development efforts on the key technological
issues that affect the production and engineering of nanocrystalline materials
that have new and superior capabilities tailored for specific commercial
applications. This focus has resulted in the Company's development of its
proprietary core technologies, including the PVS process, DPE process and
net-shaping. To protect its proprietary core technologies, the Company has been
issued patents with respect to its PVS process and the related apparatus,
applied for patents with respect to its DPE process and licenses patents related
to the synthesis of nanocrystalline materials and net-shaping.
 
CUSTOMERS AND APPLICATIONS
 
   
     The Company is in the advanced materials industry and has identified four
primary markets--electronics, structural ceramics and composites, cosmetics and
skin-care, and industrial catalysts--each of which offers the Company
significant potential for revenue growth. In addition, the Company believes
these markets provide opportunities to achieve competitive advantages based on
product performance. The Company's strategy is to collaborate with industry
leaders in these markets in order to validate the capabilities of its materials
and coordinate the development and commercial introduction of product
applications. The collaborative relationships pursued by the Company include (i)
agreed-upon specifications for the proposed commercial application of the
Company's materials; (ii) confirmation by the customer that the proposed
application appears to be commercially viable and valuable; (iii) a significant
commitment of developmental resources; (iv) agreed-upon developmental
milestones, and (v) a development path that is intended to lead to

     Following is a more detailed description of the Company's targeted markets
and its activities in specific product applications.
 
ELECTRONICS
 
     Electronics is one of the world's largest and fastest growing markets,
fueled in part by rising demand for increased computing power and information
storage requirements and the rapid growth of communications technologies. The
new levels of performance in electronics that are necessary to meet these
requirements depend, in large part, on advanced materials, especially advanced
ceramics, that enable higher performance and further miniaturization.
Increasingly, critical dimensions and performance criteria for high-speed
electronic pathways and dense platforms are measured in nanometers and angstroms
(tenths of nanometers).
 
                                       27
<PAGE>   29
 
It is at this level of performance that Nanophase believes its engineered
nanocrystalline materials have advantages that can be converted into immediate
opportunities.
 
     Nanophase's initial focus in this market has primarily been on three
product applications: (i) semiconductor polishing, (ii) coatings for
electromagnetic radiation protection and (iii) high-performance electrodes. The
Company believes that the uniformly small particle size, nearly spherical
particle morphology and clean particle surface of the Company's materials allow
such materials to provide innovative, value-added benefits for these and other
product applications in the electronics market.
 
  Semiconductor Polishing
 
     Increases in computing power require increased memory capacity, which is
achieved by fabricating smaller circuits on smoother semiconductor wafer
surfaces. These smoother surfaces are obtained by a technique called
chemical/mechanical polishing (CMP), in which an abrasive slurry is used to
polish semiconductor surfaces to a very fine finish.
 
     Polishing slurries utilizing the Company's nanometer-sized aluminum dioxide
("alumina") and cerium oxide ("ceria"), with their nearly spherical particle
shapes and uniformly small particle sizes, provide semiconductor polishing that
results in (i) significantly smoother surfaces, (ii) a faster rate of material
removal, (iii) more selective removal of material, and (iv) easier cleaning
during the manufacturing process, compared to slurries utilizing conventional
materials. The Company believes that these attributes will be an important
element in the production of semiconductor wafers with smaller geometries that
will result in increased memory capacity, faster processing speeds and lower
production costs.
 
     Nanophase has entered into a five-year requirements contract with Moyco, a
manufacturer of semiconductor polishing slurries, pursuant to which the Company
will supply its nanocrystalline alumina and ceria to Moyco. Moyco markets its
slurries to Hyundai, Samsung, IBM, Lucent and Motorola, all of which are
currently evaluating slurries containing the Company's nanocrystalline materials
for use in their next generation semiconductor manufacturing processes. The
Company has agreed to sell the materials to Moyco for this market on an
exclusive basis so long as Moyco purchases the following annual minimums
specified in the contract: 23, 50, 80, 140 and 200 tons of alumina and 4, 8, 16,
20 and 30 tons of ceria in 1997, 1998, 1999, 2000 and 2001, respectively. If
Moyco purchases the aggregate minimum quantities specified in the contract, it
will purchase approximately $30 million of the Company's materials through the
end of 2001. If Moyco fails to purchase such minimum quantities, the Company may
terminate Moyco's exclusivity, or the Company may terminate the entire contract.
In August 1997, Moyco and Ashland signed a non-binding letter of intent
pertaining to the potential purchase by Ashland of Moyco's intellectual
properties, technologies and certain other intangible assets for the
chemical/mechanical polishing of semiconductor wafers. See "Risk
Factors--Dependence on a Limited Number of Key Customers."
 
  Electromagnetic Radiation Protection
 
     Cathode ray tubes ("CRTs") utilized in television and computer monitors
emit electromagnetic radiation due to the high voltages used to generate light.
In the past, little attention was paid to the potential harmful effects of this
radiation. Recent European Economic Community regulations scheduled to go into
effect over the next several years, however, place more stringent limits on the
quantity of radiation that can be emitted by television and computer monitors.
In response to such regulations, CRT manufacturers require transparent,
conductive coatings that meet the new electromagnetic radiation standards.
 
     The materials currently used for conductive coating of CRTs have not been
proven to meet all of the new radiation requirements. Nanophase can produce a
proprietary metal oxide mixture which has a narrower particle-size distribution
and cleaner particle surfaces than currently used materials. The Company's
nanocrystalline metal oxide mixture is highly conductive and easily dispersed
and, when applied as a coating to CRTs, is expected by the Company to meet the
increased radiation shielding regulatory requirements, while maintaining the
transparency required for quality video images. The Company is actively working
with Philips pursuant to an agreement to develop a specific coating for CRTs
manufactured by Philips. This agreement
 
                                       28
<PAGE>   30
 
includes an expression of intention by Philips to purchase the Company's coating
materials if developmental milestones are met.
 
  High-Performance Electrodes
 
     Electronic medical devices require new high-performance electrodes which
deliver more precise voltages. In order to achieve such precision, the surface
area of the electrode needs to be increased substantially. As the surface area
of an electrode increases, transient signals caused by polarization at the
electrode surface are reduced. In a development program with Medtronic, a
leading manufacturer of medical devices, the Company is developing
nanocrystalline precious metals that can be directly deposited on medical-device
electrodes to create the additional surface area required to decrease
polarization. The Company believes that its material provides higher surface
area than the conventional technology currently used. The Company is working
with Medtronic to meet specific performance requirements and establish
developmental milestones.
 
  Thin-Film Materials for Semiconductor Manufacturing
 
     Nanophase has begun an early stage development program with a leading
electronic materials company for developing advanced materials for use in
semiconductor manufacturing. The objective is to develop advanced materials
which can be used to fabricate thin-films on the surfaces of semiconductors to
enable the production of semiconductor wafers with increased memory capacity,
faster processing speeds and lower production costs. Nanocrystalline materials
are used because the products require a uniform and fine-grained structure. This
product application is in an early stage of development and investigation.
 
  Flat-Panel Displays
 
     Nanophase and a Fortune 50 communications company have submitted a joint
proposal to the U.S. Department of Defense for funding to develop photonic
materials and manufacturing technology for a new generation of electronic
displays for a broad range of light-weight, low-power multi-purpose
communication devices. If funded, the two companies will work jointly to develop
the products.
 
STRUCTURAL CERAMICS AND COMPOSITES
 
     Structural ceramics are advanced compounds that offer hardness, high
strength and inertness for a broad range of industrial applications involving
harsh chemical and thermal environments. The free-flowing nature and weak
agglomeration of the Company's nearly spherical nanocrystalline particles enable
the Company to rapidly fabricate high-tolerance, dimensionally precise
structural ceramic parts without costly machining. Because the conventional
methods for forming structural ceramics involve the use of high temperatures,
high pressures or lengthy machining operations, the high costs of fabrication
have limited the usage of dimensionally-precise ceramics to only the most
critical applications. Through its net-shaping process, the Company can mold
nanocrystalline ceramic materials into fully-dense ceramic parts with little or
no machining. This process makes it possible to fabricate a variety of
dimensionally precise structural ceramic components in a short period of time
(e.g., 15 to 30 minutes for the Company's process as opposed to 4 to 8 hours for
conventional machining), at significantly lower temperatures and pressures, and
at substantially lower costs, than conventional fabrication methods.
 
     Composites, like structural ceramics, are engineered structures that
consist of diverse elements and are geared toward high-stress product
applications that require durable, resistant materials. Composites combine the
advantageous qualities of their constituent materials. The properties of these
composites depend heavily on the nature and amount of the materials that are
incorporated into the composites. For example, incorporating a hard material
like alumina into a flexible and light-weight plastic can increase the plastic's
resistance to abrasion and wear. Such an increase is related to the number of
particles of the constituent alumina. Because there are more particles in one
pound of nanocrystalline materials than in one pound of more commonly used
micron-sized particles, properties such as abrasion resistance are enhanced by
substituting nanocrystalline materials for conventionally used materials.
 
                                       29

  Composite Polymer for Oil Drilling Machinery
 
     Nanophase has entered into a one-year requirements contract with LWT, a
supplier of instrumentation to the oil drilling industry, for the supply of
abrasion-resistant composite polymers to protect down-hole data logging
equipment. The contract requires LWT to purchase a minimum of $375,000 of
materials from the Company. In this application, instrumentation is lowered into
a drilled shaft in order to provide information to the drill operator on a
continuous basis. Because drilled shafts often pass through hard rock
formations, or very abrasive layers of sandstone, the data logging instruments
must be protected from potential wear. A protective housing, or collar, is used
to protect the data logging equipment. These collars are conventionally coated
with a commercially available ceramic-filled polymer. Conventional fabrication
of these collars is difficult because the polymer is thick and must be applied
by hand. LWT requires a polymer which can be applied by automatic machinery, has
a long service life and is abrasion-resistant. Tests performed by LWT using the
Company's composite materials indicate that such materials meet these
requirements.
 
  Ceramic Components for Continuous Steel Casting
 
     The Company is collaborating with Acutus Gladwin, a leading supplier of
services and products in the steel industry, to produce a ceramic component for
use in continuous steel casting. Continuous steel casting is performed by
pouring molten steel from a ladle through a funnel-shaped nozzle into a mold
which is several hundred feet long. Current nozzles are made of a porous
alumina/graphite material and require frequent replacement due to wear. During
replacement, steel-casting lines using these nozzles must be shut down for 15 to
45 minutes while new components are installed, resulting in down-time costs of
up to approximately $25,000/hour and several tons of second-quality steel which
must be remelted or downgraded for use in lower-quality products. Nanophase
believes that its denser net-shaped ceramics in this application will
substantially increase wear resistance, resulting in significant cost savings
due to decreased downtime and less wasted or sub-standard steel. Under a
development agreement with Acutus Gladwin, the Company has successfully
completed laboratory testing of its material and prototypes are scheduled to be
field tested by the end of 1997.
 
  Ceramic Mechanical Seals
 
     Nanophase is currently fabricating prototype ceramic mechanical seals for a
Fortune 100 manufacturer of heavy equipment. The ceramic seals are designed for
use in harsh applications to prevent abrasive particles from entering mechanical
joints and to prevent oil from leaking from the joints. Conventional seals used
in these applications are commonly made of plastic composite materials and
either wear or corrode, requiring replacement after only a few thousand hours of
operation. Ceramic seals, because of their improved abrasion and corrosion
resistance, are believed by the Company to be more reliable and durable than
conventional seals. Customer-laboratory tests of prototype seal designs have
shown that Nanophase's ceramic seals can increase the service life of a seal up
to ten-fold compared to currently-used seal materials, resulting in a reduction
of equipment downtime and associated costs. In addition, Nanophase's net-shaping
process reduces or eliminates the costly diamond grinding that normally would be
required to fabricate these ceramic seals. The Company believes that reduced
manufacturing costs make these ceramic seals cost-effective for a number of
high-volume mechanical-seal applications. The Company expects field testing of
its ceramic seals to begin by the end of 1997.
 
  Ceramic Armor
 
     The Company is currently fabricating net-shaped alumina armor plates under
a development agreement with Pacific Safety, a leading Canadian armor producer.
Ceramic based armor is highly desirable because of its strength and weight
advantage over steel. It can provide the same protection at a significantly
reduced weight. However, current ceramic armor materials, made from hot-pressed
alumina or boron carbide, are either not durable enough or very costly to
fabricate, and thus have limited markets. Based on preliminary studies, the
Company believes that it will be able to produce denser, fine-grained alumina
armor tiles which will have greater durability and impact resistance than
hotpressed alumina tiles and offer a significant economic advantage over boron
carbide.

  Remotely Monitored Medical Implants
 
     In collaboration with Medtronic, Nanophase is developing a net-shaped
ceramic housing for an electronic medical device. Current housings for this
application are fabricated from metal, and while medically proven and in daily
use, they do not allow the transmission of Radio Frequency ("RF") signals. A
ceramic housing would allow the passage of RF signals and, hence, remote
wireless monitoring. Nanophase is also developing materials for medical implants
for Medtronic which can be viewed without using X-rays. Both medical devices, if
successfully developed, will require the customer to undertake long-term
clinical testing and seek FDA approval. See "Risk Factors--Governmental
Regulations."
 
COSMETICS AND SKIN-CARE
 
     The cosmetics and skin-care market is a substantial consumer of particulate
materials as active ingredients and pigments. The Company has targeted three of
its nanocrystalline materials, titanium dioxide ("titania"), iron oxide and zinc
oxide, for applications in the cosmetics and skin-care market, including
sunscreens, cosmetic colorants and topical health-care applications. Nanophase
has entered into a global distribution agreement with WCD for exclusive
distribution of its nanocrystalline materials to cosmetic and skin-care
companies. Through this distribution arrangement, the Company (i) has recently
begun commercial sales of its titania to several small cosmetics companies,
including Geurlain, the Jafra division of Gillette, Inc., Medicia Pharmaceutical
Corporation and Sunny World Co., Ltd (of Thailand), for use in sunscreens, (ii)
is shipping its iron oxides to a Fortune 500 cosmetics company for use as
cosmetic colorants, (iii) is shipping titania dispersions to that same customer
for use in a product with SPF protection, which is presently scheduled for
market introduction in the fourth quarter of 1997, and (iv) has entered into a
commercial supply contract with Schering-Plough for its nanocrystalline zinc
oxide.
 
  Topical Health-Care Applications
 
     The Company has recently entered into a four-year requirements contract
with Schering-Plough pursuant to which the Company will supply its
nanocrystalline zinc oxide to Schering-Plough for certain topical health-care
products. For example, the Company's nanocrystalline materials are being
supplied for use in new anti-fungal sprays and powders presently scheduled for
initial market introduction in the fourth quarter of 1997. Several skin-care
companies are currently evaluating Nanophase's nanocrystalline zinc oxide for
use in other topical health-care products. The Company's zinc oxide contains
uniformly small particles which contain a large number of surface area atoms.
Initial testing by the Company's customers indicates that this attribute
provides enhanced anti-fungal activity compared to conventional materials
because a lower amount of the Company's zinc oxide is needed to achieve the
desired level of activity. In addition, the Company's zinc oxide, because of its
weakly agglomerated particles, is better suited than conventional materials for
aerosol applicators.
 
  Sunscreens
 
     The market for titania-based sunscreens has rapidly expanded due to (i)
increasing consumer awareness of the harmful effects of ultraviolet ("UV") rays
and (ii) a desire to replace conventional chemical sun-block ingredients, which
can cause irritation, with "chemical-free" ingredients, such as titania. Because
the Company's nanocrystalline titania is comprised of particles that are large
enough to block UV rays, but are consistently smaller than the wave length of
visible light, it enables "chemical-free" sunscreen products to provide an
unprecedented combination of high SPF protection and transparency. In this
regard, sunscreens using Nanophase's titania provide SPF protection of 17+ with
transparency, at only 3% weight loading, whereas, based upon independent
performance results, competitive products made with conventional titania are
able to achieve SPF protection of no better than 12, require a weight loading of
5% or more and often exhibit a whitening effect on the skin. The weight loading
percentage is a measure of the amount of material in a product, by weight, in
relation to the weight of all of the materials in the product. The relationship
between SPF and weight-loading is only roughly linear; however, at these
performance points, sunscreens using the Company's titania provide 5.6 SPF
points for each percent of weight loading versus 2.4 SPF points for the
best-performing current competitive products. Nanophase's total-encapsulation
coating, based on its DPE
 
                                       31
<PAGE>   33
 
process, also makes Nanophase's titania compatible with certain skin-product
ingredients, like self-tanning ingredients, with which competitive titania is
not compatible. This compatibility enables cosmetics formulators to develop
self-tanning products which offer chemical-free protection from excessive
exposure to UV rays.
 
  Cosmetic Colorants
 
     Through its PVS and DPE processes, the Company has engineered
nanocrystalline brown, red and black iron oxides for use as coloring agents in
cosmetics. Because of their visible transparency, these iron oxides can
intensely color the skin without the caking or streaking effects caused by
conventional opaque coloring agents. This is due to the nanometer-sized
particles of Nanophase's iron oxides which absorb light without significant
visible scattering, thereby providing color without opacity. In addition, the
nearly spherical particles of Nanophase's iron oxides enable them to be
discretely encapsulated and readily dispersed to create smooth, free-flowing
cosmetic foundations which cosmetics formulators can blend to more closely match
varying skin tones.
 
INDUSTRIAL CATALYSTS
 
     Catalysts are materials that help convert, or accelerate the conversion of,
one chemical into another. The Company's PVS process allows for the fabrication
of two distinct types of solid catalysts: (i) a single pure material, such as
iron oxide, which is a widely used chemical-process catalyst for the synthesis
of hydrogen, ammonia and other bulk chemicals, and (ii) composite materials in
which a nanocrystalline metal, such as palladium, is deposited on a larger
substrate. This latter catalyst has a broad range of applications, including
polymer synthesis, hydrogen peroxide production and the conversion of petroleum
feedstock to higher value chemicals.
 
     The activity of a catalyst (i.e., the amount of desired product that can be
produced per unit weight of catalytic material) is an important measure of its
efficacy, and is related to a number of physical properties of the catalyst,
including surface area, particle size and the reactivity of atoms on the surface
of the catalytic material. Nanocrystalline materials offer better performance as
catalysts because they have a higher proportion of catalytically active surface
atoms than conventional materials. In addition to enhanced reactivity, the
Company's materials can potentially reduce costs because less catalyst is needed
to achieve a desired level of activity.
 
     Nanophase is developing a process to directly deposit nanocrystalline
metals on a substrate for use by DuPont as a catalyst in large-scale chemical
production. Early measurements have shown a two to fourfold increase in
catalytic activity over the current, chemically produced DuPont catalyst. The
Company is working with DuPont to meet specific performance requirements for
this catalyst. The Company has also begun an early-stage development program
with a Fortune 50 chemical company to produce catalysts comprised of
nanocrystalline metal oxides on larger substrates. Based on the Company's
discussions, both internally and with potential customers, additional potential
applications for PVS-produced heterogeneous catalysts include wash coats for
automotive catalysts and surface-enhanced catalysts for the chemical-process
industry.
 
TECHNOLOGICALLY-SIMILAR APPLICATIONS
 
     Although the Company focuses its efforts on product applications in the
above-mentioned markets, the Company believes there is a broad range of
technologically-similar applications, the performances of which could be
substantially improved by utilizing the Company's materials and technologies
without extensive additional engineering. Based on the Company's discussions,
both internally and with potential customers, these include applications for
fibers, textiles, plastics, paper, optical polymers, pigments and other
specialty products. These applications are primarily based on the coating or
dispersion of nanocrystalline materials produced by the PVS process. The Company
only pursues those specialty applications which fit into its business strategy
and which receive substantial support from a significant prospective customer.
 
                                       32
<PAGE>   34
 
THE COMPANY'S TECHNOLOGIES
 
     Nanophase has developed and employs several related technologies for the
engineering and production of nanocrystalline materials and product
applications, including technologies for the synthesis, surface-treatment and
dispersion of nanocrystalline materials and the fabrication of structural
ceramic components. The Company also is engaged in ongoing research and
technology-licensing activities as part of its strategy to maintain a technical
and commercial leadership position in the field of nanocrystalline materials.
 
  The PVS Process
 
     The Company uses its patented PVS process to produce nanocrystalline
powders. The PVS process is based on the formation of a physical vapor from a
selected metallic or ceramic material which is fed through a plasma reactor and
heated to a temperature above its melting point. As the temperature rises, the
atoms of this material evaporate from its surface into a stream of flowing
vapor. These evaporated atoms are then mixed with selected gases which
chemically react with the atoms. Additional gases then cool the atoms
sufficiently to condense the vapor into solid, nearly spherical clusters of
molecules. The flowing gas transports the resulting clusters to a collection
vessel. The rapid transport and cooling of the nanometric particles produce a
weakly agglomerated powder.

                               THE PVS PROCESS
- -------------------------------------------------------------------------------

                                   [CHART]
    
 
     The Company holds two patents relating to its PVS process which expire in
2013; one covers the process itself, while the other covers the apparatus used
in the process. The Company's plasma reactor embodies proprietary features which
enable the production of high-quality materials at high-volume and competitive
cost. Nanophase utilizes its PVS process to exploit the relative advantages of
physical versus chemical synthesis of nanocrystalline materials. These
advantages include the production of nanocrystalline materials with particles
that are nearly spherical, virtually free of chemical residue, uniformly small,
not strongly agglomerated, and easily engineered.
 
     The Company believes that the PVS process is a superior commercial process
in the degree of control that can be exercised over particle size and particle
size distribution. By means of controlled and subtle modifications to the PVS
process (e.g., the evaporation rate, the type or pressure of the gas, or how
quickly the
 
                                       33
<PAGE>   35
 
flow of gas carries the clusters to the collection vessel), the Company can
control the size of a material's particles, thereby altering the traits of a
substance. The Company is thus able to engineer and produce a wide range of
materials and products without substantial process and product re-engineering.
In 1995, the Company's PVS process received the R&D 100 Award given each year by
R&D Magazine to recognize the 100 most technologically significant new products
and processes in the world.
 
  Surface Treatments (The DPE Process)
 
     Many of the applications that the Company is pursuing require further
engineering of the particles produced in the PVS process in order to meet
specific application requirements. To satisfy these requirements, the Company
has developed a variety of surface-treatment technologies to stabilize, alter or
enhance the performance of nanocrystalline particles, together with technologies
to enable the particles to be dispersed in fluids or polymers. At the core of
these surface-treatment and dispersion technologies is Nanophase's proprietary
DPE process, which enables Nanophase to completely surround each nanocrystalline
particle with a durable coating. The Company has applied for a patent for its
DPE process.
 
     The DPE process can coat the surface of each nanometer-sized particle
produced by the PVS process with a proprietary polymer that is not removed by
subsequent processing. Traditional coating technologies employ strand-like
polymers that cannot completely cover the surfaces of nanometric particles. The
Company's DPE process uses polymers that are shaped like hands. When the
nanometer-sized particles are coated, the fingers of the hand collapse and
completely encapsulate each particle with a thin polymeric shell. This shell
also can be engineered to contain covalently bound spacer groups of controllable
size that function to prevent particles from sticking to each other. The
coatings enable the particles to be uniformly dispersed in a wide range of
media, including water, cosmetic emollients, plastics and polymers, thus
enabling these materials to be used in applications ranging from highly
transparent sunscreens to dense opaque coatings.
 
  Net-Shaping
 
     Nanophase has developed a proprietary process whereby it net-shapes its
nanocrystalline ceramic materials produced by the PVS process to rapidly
fabricate precise, high-tolerance industrial ceramic parts without costly
machining. This net-shaping technology was developed in collaboration with the
Company's subcontractors, Lockheed Missiles & Space Co., Inc. ("LMSC") and
Caterpillar, Inc., under an Advanced Technology Program ("ATP") contract funded
by the U.S. Department of Commerce.
 
     The Nanophase technologies relevant to net-shaping involve (i) the
production of nanocrystalline ceramic materials in commercial quantities, (ii)
the consolidation of Nanophase's ceramic materials into dense nanocrystalline
preforms without exaggerated particle growth, and (iii) net-shape forming of
fully-dense, precisely-shaped ceramic parts.

                                   [CHART]
    
 
     The conventional fabrication of structural ceramics involves machining that
uses diamond tools. This process is costly, time consuming and often produces
highly stressed ceramic parts and components with structural flaws. Nanophase's
process enables fabrication of ceramic parts and components using significantly
lower temperatures and pressures than used by conventional fabrication methods
(e.g., 1300-1500 degreesC and 2000-4000 psi, as compared to up to 1700 degreesC
and 100,000 psi). This technology enables the Company to fabricate dimensionally
precise ceramic components in a short period of time without costly machining
(e.g., 15 to 30 minutes for the Company's process as opposed to 4 to 8 hours for
conventional machining). This rapid deformation processing is made possible by
the consistent ultrafine particle size of the Company's nanocrystalline ceramic
materials, the Company's ability to control the consolidation of such particles
into preforms of high and uniform density, and the ability of the ultrafine
particles to easily slide over one another in the forming process. The Company's
net-shaping technology produces ceramic products with a variety of detailed
shapes, high tolerances and smooth surface finishes that can be tailored to a
customer's needs.
 
     Following the successful completion of the ATP program, the Company entered
into a research, development and prototyping agreement with LMSC whereby the
Company funds LMSC to perform design, prototyping and research and development
tasks related to net-shaping using technology developed during the ATP project.
LMSC currently designs, engineers and fabricates prototypes to the Company's
specifications for the Company's commercial customers. Technology developed
during the ATP project is jointly owned by the Company and LMSC. New technology
developed under the current arrangement between LMSC and the Company is
wholly-owned by the Company and, under the terms of the arrangement, LMSC can
use the newly-developed technology only for its internal research.
 
  Other Technologies
 
     The Company constantly seeks to develop new technologies relating to
nanocrystalline-based materials through ongoing research and development
activities and collaborations with industrial, university and government
research programs. For example, the Company is developing a new generation of
metallic and ceramic precursors to be processed into nanocrystalline materials.
Such activities are intended to enable the Company to develop new product
applications and offer more materials with enhanced capabilities.

MANUFACTURING AND FACILITIES
 
   
     Nanophase operates a 20,000 square-foot production and research facility in
Burr Ridge, Illinois, a suburb of Chicago, which also serves as the Company's
administrative headquarters. The Company also operates a smaller facility in
Chicago, Illinois, for coating nanocrystalline materials using its DPE process.
The Company believes its Burr Ridge facility is the first in the world that is
dedicated to the commercial-scale development and production of physically
synthesized nanocrystalline materials. The Company's operations in Burr Ridge
are registered under ISO 9001 standards, and the Company believes its
manufacturing operations are in compliance with the cGMP requirements of the
FDA.
    
 
     Through the first three quarters of 1997, 15 PVS plasma reactors were
operational and producing various nanocrystalline materials at the Burr Ridge
facility. The throughput of each reactor depends on many factors, including the
mix of products produced, the commencement, expiration or termination of
development programs, the status of tests and evaluations of samples and
prototypes and production yields. In the third quarter of 1997, the Burr Ridge
facility operated 24 hours a day, seven days a week.
 
     Each PVS plasma reactor is comprised of modular equipment which is designed
and assembled to the Company's proprietary specifications. These modular
reactors provide flexibility in the expansion of the Company's manufacturing
capability. In the third quarter of 1997, the Company began the installation of
eight additional PVS plasma reactors in the Burr Ridge facility. The Company
expects that such PVS plasma reactors will be operational by the end of 1997. In
addition, the Company expects to increase the throughput per reactor as it
increases the efficiency and yields of its PVS process and decreases the amount
of downtime for each reactor. The Company believes that additional manufacturing
capacity will be required in 1998 and intends to use a portion of the net
proceeds from this offering for the expansion of its manufacturing facilities.
See "Use of Proceeds." Also operational within the Burr Ridge facility is a
quality control laboratory designed for the dual purpose of validating
operations to cGMP and ISO standards, and production process control. This
laboratory is equipped to handle all routine analytical and in-process
techniques that are currently required by the Company. In addition, capability
for specialized analytical and physical measurements currently is available at
Argonne upon terms which the Company believes are reasonable and adequate. The
Company leases its Burr Ridge facility pursuant to an agreement which expires in
September 1999. The Company has options to extend the lease for up to five
additional years.
 
     Based on the Company's current product mix, the Company's coating facility
has the capacity to coat those nanocrystalline materials which it desires to
coat. The Company believes that its coating capacity is adequate to support the
Company's anticipated 1998 production plans. The Company subleases its Chicago
facility pursuant to a one-year agreement which automatically renews unless
terminated by either party upon proper notice.
 
MARKETING
 
     The Company believes that one of its principal strengths is its marketing
department, the members of which have experience in each of the Company's
targeted markets. These individuals are often teamed with the Company's
scientists and researchers to demonstrate the advantages of the Company's
materials and product applications to potential customers. The Company's
scientists, engineers and marketing personnel attend and speak at advanced
materials symposia, publish articles in scientific journals and participate in
selected industry trade shows. In addition, the Company uses a web page on the
internet, advertisements in selected industry and trade journals, and
specification sheets and corporate brochures.
 
     The Company also markets its materials through distributors in certain
application areas where the requirements for ongoing development and technical
support by Nanophase are not substantial, or where the distributor has existing
customer relationships, marketing or post-processing infrastructure, or
companion products or services that may enable Nanophase to enter the market
more quickly. For example, pursuant to a global distribution agreement, WCD
exclusively distributes Nanophase's nanocrystalline titania, iron oxides and
zinc oxide to the cosmetics and skin-care market. See "--Customers and
Applications--Cosmetics and Skin-Care."
 
                                       36
<PAGE>   38
 
     As part of its strategy to gain access to foreign markets, Nanophase has
entered into an agreement with a subsidiary of Itochu, formerly C. Itoh, for the
distribution of Nanophase's materials in broad-based industrial markets
throughout Asia. The agreement is intended to enable Nanophase to quickly
establish foothold positions in Asian markets by utilizing the technology and
market-support capabilities of Itochu. The agreement does not target specific
materials or applications; however, Itochu is pursuing high-volume industrial
applications in electronics, industrial ceramics and catalysts.
 
     Because virtually all of the product applications for the Company's
materials are new and innovative, in order for the Company to penetrate its
targeted markets, it must participate in a multi-step process that includes
initial discussions of the product application which highlight the advantages of
the Company's nanocrystalline materials, proof of concept, proof of feasibility
within the specific application, and evaluations of cost and manufacturability.
Completion of this evaluation process usually takes at least 18 months, and may
take several years.
 
RESEARCH AND DEVELOPMENT
 
     The near-term objective of the Company's research and process-development
activities is to develop and consistently produce sufficient commercial
quantities of application-specific nanocrystalline materials to meet the
Company's near-term requirements. Although the Company has de-emphasized the
pursuit of revenue from government research contracts, a key component of the
Company's long-term research and development strategy is to identify and develop
relationships with leading industrial, university and government research
programs across the United States and internationally to leverage the Company's
technological and scientific capabilities. The Company believes that these
research relationships may provide accelerated introduction of new technologies
into its product applications, early indications of new technology developments
which could enhance or compete with the Company's nanocrystalline materials, and
high-value improvements in its current key technologies. The Company will also
continue its efforts to attract and retain top scientists and engineers, which
management believes will enable the Company to maintain a long-term leadership
position in the nanocrystalline materials field.
 
   
     The Company's total research and development expenses during the nine
months ended September 30, 1997 and fiscal years 1996, 1995 and 1994 were
$571,210 and $677,284, $485,059 and $456,162, respectively. The future success
of the Company will depend in large part upon its ability to keep pace with
evolving advanced materials technologies and industry standards, and there can
be no assurance it will be able to do so. See "Risk Factors--Rapid Technological
Change" and "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
    
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
   
     The objective of Nanophase's intellectual property activities is to
implement ongoing strategies that maximize and protect the proprietary rights of
the Company. These strategies encompass (i) obtaining patents and trademarks
based on Nanophase inventions and products, and (ii) licensing third-party
patents to expand the Company's technology base and prevent Nanophase from being
blocked should future developments require use of technology covered by those
patents. To date, the Company has not been required to license technologies or
design around other parties' patents in order to avoid claims of patent
infringement.
    
 
     Nanophase currently owns or licenses an aggregate of 16 United States
patents and patent applications: two issued patents owned directly by Nanophase;
three pending patent applications owned directly by Nanophase; and eleven
patents licensed from third parties.
 
     Two United States patents have been issued to Nanophase: one covering its
PVS process for the synthesis of nanocrystalline materials, and the other
covering the related apparatus. The patents expire in July 2013. Additional
United States patent applications filed by the Company include applications
relating to nanocrystalline materials, plasma sensors and the coating of metal
oxides. Foreign patent applications owned directly by Nanophase are pending in
Australia, Europe and Japan for the PVS process and apparatus. An international
patent application owned by the Company for the coating of ceramic powders is
also pending
 
                                       37
<PAGE>   39
 
under the Patent Cooperation Treaty, with Australia, Canada, Europe and Japan
designated for the national phase of the application.
 
     The Company holds the following licenses of United States patents: an
exclusive worldwide license of two patents owned by ARCH Development Corporation
which embody a laboratory-scale method and apparatus for making nanocrystalline
materials; a non-exclusive license from Research Development Corporation of
Japan of four patents which embody early laboratory-scale work in the physical
synthesis of nanocrystalline materials; a non-exclusive license of two patents
owned by Hitachi, Ltd. which are related to the synthesis of nanocrystalline
materials; and a remainder-exclusive license of three patents held by Cornell
University relating to a laboratory-scale process for net-shaping of a limited
range of materials. Other than the license from Research Development Corporation
of Japan, which remains in force until May 2006 and is extendable upon further
agreement, each of the licenses lasts for the life of their respective patents.
Under each of the licenses, the Company is obligated to pay the licensor
royalties equal to a percentage of net sales of products which embody the
licensed technology.
 
   
     The Company requires its employees, consultants, outside scientific
collaborators and other advisors to execute confidentiality and proprietary
rights agreements upon the commencement of employment or consulting
relationships with the Company. These agreements generally provide that all
confidential information developed or made known to the individual during the
course of the individual's relationship with the Company will be kept
confidential and will not be disclosed to third parties except in specific
circumstances. In the case of research employees, the agreements also provide
that all inventions made by the individual shall be the exclusive property of
the Company. There can be no assurance, however, that these agreements will
provide meaningful protection for the Company's trade secrets, know-how or
patent rights or will provide the Company with adequate remedies in the event of
unauthorized use or disclosure of such information. In addition, because none of
the Company's employees have entered into noncompetition agreements with the
Company, they may become competitors of the Company upon termination of
employment. See "Risk Factors--Dependence on Patents and Protection of
Proprietary Information."
    
 
COMPETITION
 
     Within each of its targeted markets and product applications, Nanophase
faces current and potential competition from numerous chemical companies, as
well as the in-house capabilities of several of its current and potential
customers. For example, with regard to semiconductor wafer polishing, Cabot,
Rodel Incorporated, Fujimi Corporation (of Japan) and Solution Technology
Incorporated, all market polishing slurries for CMP. In addition, Cabot,
Baikowski International Corporation and Norton Company (a unit of Compagnie De
Saint-Gobain) all manufacture their own ultrafine alumina. In the cosmetics and
skin-care market, various companies manufacture their own sub-micron titania
(Tioxide Specialties Limited, Tayca Corporation (of Japan), Ishihara Sangyo
Kaisha, Ltd., Kemira Oy, Degussa AG and DuPont), iron oxide (Sun Chemical
Corporation, Harcros Pigments Incorporated) and zinc oxide (Zinc Corporation of
America) by chemical or other means. In structural ceramics, the Company
competes against manufacturers of ceramic composites who machine such composites
for specific product applications. In the catalysts market, the Company faces
competition from companies that chemically deposit metal oxides onto substrates.
Although Nanophase believes that its materials and technologies are superior to
the competitive materials and technologies that are utilized by these companies,
such companies represent significant competitive risks to Nanophase because they
have substantially greater financial and technical resources, larger research
and development staffs, and greater manufacturing and marketing capabilities
than the Company. See "Risk Factors--Competition."
 
     The Company also faces potential competition from Vacuum Metallurgical Co.,
Ltd. of Japan ("Vacuum Metallurgical"), which manufactures nanocrystalline
materials and equipment. Currently, the Company does not compete with Vacuum
Metallurgical, but there can be no assurance that Vacuum Metallurgical will not
develop products or manufacturing capabilities to compete with the Company in
the future. Potential competitive risks are also represented by numerous small
development companies engaged in the development of nanocrystalline materials,
such as Plasma Quench Technologies, Inc. and Nanopowder Enterprises, Inc. Most
of these companies are associated with university or national laboratories and
use chemical and physical methods to produce nanocrystalline materials.
Nanophase believes that most of such companies are engaged
 
                                       38
<PAGE>   40
 
primarily in funded research, and is not aware of any such company with
commercial production capability. However, there can be no assurance that such
companies will not represent significant competitive risks in the future. See
"Risk Factors--Competition."
 
GOVERNMENTAL REGULATIONS
 
     The Company's Chicago facility, which houses its coating operations, is a
"small quantity generator" of hazardous materials, including ethanol, under RCRA
and, as a result, is subject to stringent federal, state and local regulations
governing the handling, storage and disposal of such materials. To date, the
Company has not been required to make substantial expenditures for preventive or
remedial action with respect to the hazardous materials it uses. The manufacture
and use of certain of the products which contain the Company's nanocrystalline
materials are also subject to governmental regulation. As a result, the Company
is required to adhere to the FDA's cGMP requirements and similar regulations in
other countries which include testing, control and documentation requirements
enforced by periodic inspections.
 
     In addition, both of the Company's facilities and all of its operations are
subject to the plant and laboratory safety requirements of various occupational
safety and health laws. To date, those regulations have not materially
restricted or impeded the Company's operations. See "Risk Factors--Governmental
Regulations."
 
EMPLOYEES
 
   
     On September 30, 1997, the Company had a total of 61 full-time employees,
11 of whom hold advanced degrees. Of the full-time employees, 9 are engaged in
research, development and engineering, 32 are engaged in manufacturing, 4 are
engaged in quality control, 7 are engaged in marketing and sales, and 9 are
engaged in general management, finance and administration. The Company also
currently engages two scientists as consultants on a regular basis, one of whom
is Dr. Richard W. Siegel, a co-founder and director of the Company. None of the
Company's employees is covered by a collective bargaining agreement. The Company
considers its relations with its employees to be good.
    
 
LEGAL PROCEEDINGS
 
     The Company is not a party to any litigation and is not aware of any
pending or threatened litigation against the Company that could have a material
adverse effect on the Company's business, results of operations or financial
condition.

with Robert W. Cross which continues his employment as President and Chief
Executive Officer of the Company, which began in February 1993. Mr. Cross'

automatically renewed for successive one year periods unless 90-day prior
written notice of termination is given by the Company or Mr. Cross. If Mr.
Cross' employment is terminated other than for "cause" (as such term is defined
in Mr. Cross' employment agreement), Mr. Cross will receive severance benefits
in an amount equal to Mr. Cross' base salary for 26 weeks.
 
     The Company has also entered into an employment agreement with Dennis J.
Nowak, pursuant to which Mr. Nowak became Vice President -- Finance and

effective September 1996. Mr. Nowak's employment agreement provides for an
annual base salary of $140,000, with increases to be determined by the Company's
Board of Directors, at its discretion. In addition, Mr. Nowak was granted
options to purchase 57,900 shares of Common Stock at an exercise price of $3.886
per share, with options for one-fifth of such shares becoming exercisable on
each of the first five anniversaries of Mr. Nowak's employment. If employed by
the Company at such time, the agreement further provides that Mr. Nowak will be
entitled to a bonus of $35,000 upon the Company's successful completion of an
initial public offering and a bonus of $35,000 which was paid on the first
anniversary of his employment. No term has been assigned to Mr. Nowak's

"cause" (as such term is defined in Mr. Nowak's employment agreement), Mr. Nowak
will receive severance benefits in an amount equal to Mr. Nowak's base salary
for 26 weeks.

(1) The grant dates are ten years prior to the respective expiration dates.
 
   
(2) Potential realizable value is calculated assuming that the fair market value
    on the date of the grant, which equals the exercise price, appreciates at
    the indicated annual rate (set by the Securities and Exchange Commission
    (the "Commission")), compounded annually, for the term of the option. Using
    the assumed initial public offering price of $10.00 for purposes of this
    calculation (pursuant to the rules of the Commission), the potential
    realizable values of the options granted in 1996 to Mr. Cross and Drs. Freed
    and Brotzman is approximately $3,253,798, $1,697,634 and $1,933,416,
    respectively, at a 5% assumed annual appreciation rate, and approximately
    $5,181,130, $2,703,199 and $3,078,642, respectively, at a 10% assumed annual
    appreciation rate. The 5% and 10% assumed rates of appreciation are mandated
    by the rules of the Commission and do not represent the Company's estimate
    or projection of future increases in the price of its Common Stock.
    
 
(3) Subject to certain restrictions, these options vest pro rata over a
    five-year period on each of the first five anniversaries of the date of
    grant.
 
(4) Subject to certain restrictions, these options vest eight years from the
    date of grant, subject to an earlier five-year period if specified
    performance targets for 1997 are met.

(1) The value per option is calculated by subtracting the exercise price of the
    option from the fair market value of the option shares at December 31, 1996

    on the most recent price prior to December 31, 1996 at which the Company had

STOCK OPTION PLAN
 
   
     Effective January 13, 1992 and as amended and restated on April 6, 1997,
the Company's Board of Directors adopted the Stock Option Plan, pursuant to
which options to acquire up to 2,758,032 shares of Common Stock (2,671,182 of
which are reserved for issuance to employees and consultants and 86,850 of which
are reserved for issuance to Outside Directors) may be granted to the Company's
employees, consultants or Outside Directors, as the Committee may from time to
time designate. During any calendar year, stock options for no more than 100,000
shares of Common Stock may be granted to any individual. The stock options
expire no more than ten years from the date of grant; provided, however, that in
the case of stock options granted to individuals who at the time of such grant
own more than 10% of the voting power of the Company's stock, the options shall
expire no more than five years from the date of grant. 737,067 of the 1,557,684
currently outstanding options vest eight years following the grant date, subject
to accelerated vesting if specified performance targets are met. Of the
remaining 820,617 outstanding options, 803,247 vest over a five-year period and
17,370 vest over a three-year period. Exercise prices are determined by the
Committee, but may not be less than the fair market value of the Common Stock as
determined by the Committee as of the date of issuance of each stock option;
provided, however, that exercise prices for options granted to employees who own
more than 10% of the Company's Common Stock may not be less than 110% of the
fair market value of the Common Stock as determined by the Committee as of the
date of issuance of each such stock option.
    
 
401(K) PLAN
 
     Effective June 30, 1995, the Company adopted the Nanophase Technologies
Corporation 401(k) and Profit Sharing Plan (the "401(k) Plan") covering all of
the Company's employees who meet prescribed service requirements. Pursuant to
the 401(k) Plan, employees may elect to reduce their current compensation by up
to fifteen percent, but not to exceed the statutorily prescribed annual limit
($9,500 in 1997), and have the amount of such reduction contributed to the
401(k) Plan. The 401(k) Plan is intended to qualify under Section 401 of the
Internal Revenue Code so that employee contributions to the 401(k) Plan, and
income earned on such contributions, are not taxable to employees until
withdrawn from the 401(k) Plan. Each participant's contributions are fully
vested. The Company, at the sole discretion of the Company's Board of Directors,
may make additional or "matching" contributions under the 401(k) Plan, which
contributions are not to exceed statutorily prescribed limits. The Company has
not made any such contributions to the 401(k) Plan since its inception.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     Pursuant to the provisions of the Delaware General Corporation Law
("DGCL"), the Company, upon its reincorporation in Delaware, will adopt
provisions in its Certificate of Incorporation which eliminate the personal
liability of its directors to the Company or its stockholders for monetary
damages for breach of their fiduciary duty as a director to the fullest extent
permitted by the DGCL except for liability (i) for any breach of their duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) for unlawful payments of dividends or unlawful stock repurchases or
redemptions, or (iv) for any transaction from which the director derived an
improper personal benefit. The provisions of the Company's Certificate of
Incorporation do not affect a director's responsibilities under any other laws,
such as the federal securities laws or state or federal environmental laws.
 
     The Certificate of Incorporation will also contain provisions which require
the Company to indemnify its directors, and permit the Company to indemnify its
officers and employees, to the fullest extent permitted by Delaware law,
including those circumstances in which indemnification would otherwise be
discretionary, except that the Company shall not be obligated to indemnify any
such person (i) with respect to proceedings, claims or actions initiated or
brought voluntarily by any such person and not by way of defense, or (ii) for
any amounts paid in settlement of an action indemnified against by the Company
without the prior written consent of the Company. Prior to consummation of this
offering, the Company intends to (a) enter into indemnity agreements with each
of its directors providing for such indemnification and (b) obtain directors'
and officers' liability insurance.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     In addition to transactions described under "Management--Compensation
Committee Interlocks and Insider Participation," the following relationships and
transactions have been effected involving the Company and its directors,
executive officers and principal stockholders.
 
     The Company leased its original office space from ARCH Development
Corporation, formerly an affiliate of Mr. Lazarus, a director of the Company,
under a sublease agreement which expired in November 1996. Monthly lease
payments amounted to $3,600. When the Company moved to its Burr Ridge facility
in 1995, it entered into a sublease of this office space and received monthly
rental payments under the sublease of $2,200 per month through November 1996.
 
     The Company entered into a consulting agreement with Dr. Richard W. Siegel,
a co-founder and director of the Company, in May 1990. Pursuant to this
agreement, Dr. Siegel renders consulting services to the Company with respect to
applications for, and commercialization of, nanocrystalline materials. The
original term of the agreement was for 5 years, and the agreement is renewable
for successive one-year terms unless terminated by Dr. Siegel or the Company.
Payment to Dr. Siegel under this agreement currently amounts to $2,500 per
month.
 
     Prior to joining the Company in September 1996, Dennis J. Nowak, the
Company's Vice President--Finance and Administration, Chief Financial Officer,
Treasurer and Secretary, was a partner of Ernst & Young LLP, where he was
responsible for overseeing the audit of the Company's financial statements.
Ernst & Young LLP has been the Company's financial accountants since 1993.
 
   
     Pursuant to a severance benefit agreement with Dr. John C. Parker, the
Company's Vice President--Technology, the Company has established a trust in the
amount of $80,000. Interest was credited to the trust until the funds held in
trust became equal to $80,000. Payments from the trust to Dr. Parker will be
required in the event the Company terminates his employment, as defined in Dr.
Parker's agreement, before November 15, 1999. Upon consummation of this
offering, the funds in the trust will revert to the Company.
    
 
     The Company intends that any future transactions between the Company and
its officers, directors and affiliates will be on terms no less favorable to the
Company than can be obtained from unaffiliated third parties, and any
transactions with such persons will be approved by a majority of the Company's
outside directors or will be consistent with policies approved by such outside
directors.

                          DESCRIPTION OF CAPITAL STOCK
 
   
     The authorized capital stock of the Company consists of 25,000,000 shares
of Common Stock, $.01 par value per share, and 17,000,000 shares of preferred
stock, $.01 par value per share.
    
 
     The following summary of certain provisions relating to the Common Stock
and preferred stock does not purport to be complete and is subject to, and
qualified in its entirety by, provisions of applicable law, and by the
provisions of the Company's Certificate of Incorporation and Bylaws that are
included as exhibits to the Registration Statement of which this Prospectus is a
part.
 
COMMON STOCK
 
     The Company currently has 77,586 shares of Common Stock outstanding and
held by two holders of record. 13,234,029 shares of Common Stock will be
outstanding upon consummation of the Preferred Stock Conversion and this
offering. Subject to the rights of holders of preferred stock, the holders of
outstanding shares of Common Stock are entitled to share ratably in dividends
declared out of assets legally available therefor at such time and in such
amounts as the Board of Directors may from time to time lawfully determine. Each
holder of Common Stock is entitled to one vote for each share held. Subject to
the rights of holders of any outstanding preferred stock, upon liquidation,
dissolution or winding up of the Company, any assets legally available for
distribution to stockholders as such are to be distributed ratably among the
holders of the Common Stock at that time outstanding. All shares of Common Stock
currently outstanding are, and all shares of Common Stock offered by the Company
hereby when duly issued and paid for will be, fully paid and nonassessable, not
subject to redemption and assessment and without conversion, preemptive or other
rights to subscribe for or purchase any proportionate part of any new or
additional issues of any class or of securities convertible into stock of any
class.
 
PREFERRED STOCK
 
     The Company currently has 8,156,443 shares of Preferred Stock outstanding
and held by 176 holders of record. Pursuant to the Preferred Stock Conversion,
all of the issued and outstanding shares of Preferred Stock will convert, upon
the consummation of this offering, into 8,156,443 shares of Common Stock. Thus,
the following information does not pertain to the currently outstanding
Preferred Stock, but rather the preferred stock that may be issued in the future
as provided in the Company's Certificate of Incorporation. Preferred stock may
be issued by the Company in series from time to time with such designations,
relative rights, priorities, preferences, qualifications, limitations and
restrictions thereof, to the extent that such are not fixed in the Company's
Certificate of Incorporation, as the Board of Directors determines. The rights,
preferences, limitations and restrictions of different series of preferred stock
may differ with respect to dividend rates, amounts payable on liquidation,
voting rights, conversion rights, redemption provisions, sinking fund provisions
and other matters. The Board of Directors may authorize the issuance of
preferred stock which ranks senior to the Common Stock with respect to the
payment of dividends and the distribution of assets on liquidation. In addition,
the Board of Directors is authorized to fix the limitations and restrictions, if
any, upon the payment of dividends on Common Stock to be effective while any
shares of preferred stock are outstanding. The Board of Directors, without
stockholder approval, may issue preferred stock with voting and conversion
rights which could adversely affect the voting power of the holders of Common
Stock. The issuance of preferred stock may have the effect of delaying,
deferring or preventing a change in control of the Company. The Company has no
present intention to issue shares of preferred stock.
 
WARRANTS
 
     The Company currently has warrants to purchase a total of 662,287 shares of
Common Stock outstanding at an exercise price of $1.123 per share. The warrants
expire February 8, 2003 or one year later if at such time the shares of Common
Stock underlying the warrants are required to be or are in the process of being
registered under the Securities Act. The number of shares issuable upon exercise
of the warrants is subject to proportionate adjustment in the event of stock
splits, stock dividends and similar events.

CERTAIN CORPORATE PROVISIONS
 
     Upon the consummation of this offering, the Company will be subject to the
provisions of Section 203 of the DGCL. In general, this statute prohibits a
publicly held Delaware corporation from engaging, under certain circumstances,
in a "business combination" with an "interested stockholder" for a period of
three years after the date of the transaction in which the person becomes an
interested stockholder, unless either (i) prior to the date at which the
stockholder became an interested stockholder the board of directors approved
either the business combination or the transaction in which the person becomes
an interested stockholder, (ii) the stockholder acquires more than 85% of the
outstanding voting stock of the corporation (excluding shares held by directors
who are officers or held in certain employee stock plans) upon consummation of
the transaction in which the stockholder becomes an interested stockholder or
(iii) the business combination is approved by the board of directors and by
two-thirds of the outstanding voting stock of the corporation (excluding shares
held by the interested stockholder) at a meeting of the stockholders (and not by
written consent) held on or subsequent to the date of the business combination.
An "interested stockholder" is a person who, together with affiliates and
associates, owns (or at any time within the prior three years did own) 15% or
more of the corporation's voting stock. Section 203 defines a "business
combination" to include, without limitation, mergers, consolidations, stock
sales and asset based transactions and other transactions resulting in a
financial benefit to the interested stockholder.
 
     Upon reincorporation in Delaware, the Company's Certificate of
Incorporation and Bylaws will contain a number of provisions relating to
corporate governance and to the rights of stockholders. Certain of these
provisions may be deemed to have a potential "anti-takeover" effect in that such
provisions may delay, defer or prevent a change of control of the Company. These
provisions include (i) a requirement that stockholder action may be taken only
at stockholder meetings; (ii) the authority of the Board of Directors to issue
series of preferred stock with such voting rights and other powers as the Board
of Directors may determine; (iii) notice requirements in the Bylaws relating to
nominations to the Board of Directors and to the raising of business matters at
stockholders meetings; and (iv) the classification of the Board of Directors
into three classes, each serving for staggered three year terms. See "Management
- -- Executive Officers and Directors."
 
REGISTRATION RIGHTS
 
     Pursuant to the Registration Rights Agreement, the holders of shares of
Common Stock (including the shares of Common Stock issued pursuant to
consummation of the Preferred Stock Conversion) and additional shares of Common
Stock issuable upon the exercise of outstanding warrants (collectively, the
"Registrable Securities") are entitled to certain demand registration rights.
Under the Registration Rights Agreement, subject to certain exceptions, the
holders of at least 60% of the Registrable Securities may require the Company to
use its best efforts to register such Registrable Securities on one occasion for
public resale. If the Company is entitled to register the Registrable Securities
on a Form S-2 or Form S-3, one or more holders of the Registrable Securities may
request the Company to register such Registrable Securities on one of such
forms. In addition, whenever the Company proposes to register any of its
securities under the Securities Act, the holders of Registrable Securities are
entitled, subject to certain restrictions, to include their Registrable
Securities in such registration. Except for a limited circumstance, the Company
is required to bear all registration expenses in connection with the
registration of Registrable Securities (other than underwriting discounts and
commissions). See "Underwriting."
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is LaSalle National
Bank, Chicago, Illinois.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to this offering, there has been no public market for the Common
Stock. Sales of substantial amounts of Common Stock in the public market, or the
availability of such shares for sale, could adversely affect the market price of
the Common Stock.
 
     Upon completion of this offering, the Company will have an aggregate of
13,234,029 shares of Common Stock outstanding, assuming no exercise of the
Underwriters' over-allotment option and no exercise of outstanding options or
warrants after the date hereof. Of these shares, the 5,000,000 shares sold in
this offering will be freely tradable without restriction or further
registration under the Securities Act, unless held by "affiliates" of the
Company, as that term is defined in Rule 144 promulgated under the Securities
Act. The remaining 8,234,029 shares of Common Stock outstanding upon completion
of this offering will be Restricted Shares.
 
   
     All directors and executive officers of the Company have agreed with the
Underwriters that, for a period of 180 days from the date of this Prospectus,
they will not offer to sell or otherwise sell, dispose of or grant rights with
respect to any shares of Common Stock, now owned or hereafter acquired directly
by such holders or with respect to which they have the power of disposition,
otherwise than with the prior written consent of DLJ. The stockholders of the
Company, pursuant to the lock-up provisions of stock purchase agreements to
which they and the Company are a party, and the optionholders of the Company,
pursuant to agreements with the Company which they must sign upon exercise of
their options, have agreed or will agree, as the case may be not to sell, make
any short sale of, loan, grant any option for the purchase of, or otherwise
dispose of their shares of Common Stock for a period of 180 days from the date
of this Prospectus, without the prior written consent of DLJ. As a result of
these contractual restrictions, notwithstanding possible earlier eligibility for
sale under the provisions of Rules 144, 144(k) and 701 of the Securities Act,
shares subject to lock-up provisions or agreements will not be salable until the
180-day lock-up periods expire unless prior written consent is received from
DLJ. Any early waiver of the lock-up period by DLJ, which, if granted, could
permit sales of a substantial number of shares and could adversely affect the
trading price of the Company's shares, may not be accompanied by an advance
public announcement by the Company. See "Underwriting."
    
 
     Taking into account the lock-up provisions and agreements, the number of
shares that will be available for sale in the public market under the provisions
of Rules 144 and 144(k), will be as follows: (i) approximately 7,485,940
Restricted Shares will be eligible for sale 180 days from the date of this
Prospectus, subject in some cases to the volume limitations and other
restrictions of Rule 144, and (ii) the remaining 748,089 Restricted Shares will
become eligible for sale under Rule 144 in June, August or September 1998, as
the case may be.
 
     Beginning 90 days after the effective date of the Registration Statement,
certain shares issued or issuable upon exercise of options granted by the
Company prior to the effective date of the Registration Statement will also be
eligible for sale in the public market pursuant to Rule 701 under the Securities
Act, subject to pre-existing lockup agreements. In general, Rule 701 permits
resales of shares issued pursuant to certain compensatory benefit plans and
contracts commencing 90 days after the issuer becomes subject to the reporting
requirements of the Securities Exchange Act of 1934, as amended, in reliance
upon Rule 144 but without compliance with certain restrictions, including the
holding period requirements, contained in Rule 144.
 
     In general, under Rule 144 a person (or persons whose shares are
aggregated) who has beneficially owned Restricted Shares for at least one year,
including persons who may be deemed "affiliates" of the Company, would be
entitled to sell within any three-month period a number of shares that does not
exceed the greater of one percent of the number of shares of Common Stock then
outstanding or the average weekly trading volume of the Common Stock during the
four calendar weeks preceding the filing of a Form 144 with respect to such
sale. Sales under Rule 144 are also subject to certain manner of sale provisions
and notice requirements and to the availability of current public information
about the Company. In addition, a person who is not deemed to have been an
affiliate of the Company at any time during the 90 days preceding a sale, and
who has beneficially owned for at least two years the shares proposed to be
sold, would be entitled to sell such shares under Rule 144(k) without regard to
the requirements described above. The Company is unable to estimate
 
                                       53
<PAGE>   55
 
accurately the number of Restricted Shares that will be sold under Rule 144
because this will depend in part on the market price for the Common Stock, the
personal circumstances of the seller and other factors.
 
   
     Pursuant to Rule 144 and upon expiration of the one-year holding period, an
additional 662,287 shares of Common Stock will be available for sale upon the
exercise of outstanding warrants. Options to purchase 1,557,684 shares are
currently issued and outstanding under the Stock Option Plan (of which 377,792
are currently vested). See "Management--Stock Option Plan." All of these shares
issuable upon exercise of the warrants or the options are or will be subject to
lock-up provisions discussed herein.

     The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase and accept delivery of the shares of Common Stock
offered hereby are subject to the approval by their counsel of certain legal
matters and to certain other conditions. The Underwriters are obligated to
purchase and accept delivery all the shares of Common Stock offered hereby
(other that those shares covered by the over-allotment describe below) if any
are purchased.
 
     The Underwriters initially propose to offer the shares of Common Stock in
party directly to the public at the initial public offering price set forth on
the cover of this Prospectus and in part to certain dealers (including the
Underwriters) at such price less a concession of not in excess of $     per
share. The Underwriters may allow, and such selected dealers may reallow to
certain other dealers, a concession not in excess of $     per share. After the
initial offering of the Common Stock, the public offering price and other
selling terms may be changed by the Representatives at any time without notice.
The Underwriters do not intend to confirm sales to any accounts over which they
exercise discretionary authority.
 
     The Company has granted to the Underwriters an option, exercisable within
30 days after the date of this Prospectus, to purchase up to 750,000 additional
shares of Common Stock at the initial public offering price less underwriting
discounts and commissions. The Underwriters may exercise such option solely to
cover overallotments, if any, made in connection with this offering. To the
extent that the Underwriters exercise such option, each Underwriter will become
obligated, subject to certain conditions, to purchase its pro rata portion of
such additional shares based on such Underwriter's percentage underwriting
commitment as indicated in the preceding table.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.
 
   
     The Company and its executive officers and directors have agreed not to
offer, pledge, sell, offer to sell, contract to sell, sell any option or
contract to purchase, purchase any option or contract to sell, grant any option,
right or warrant to purchase or otherwise dispose of, directly or indirectly,
any shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock, or enter into any similar agreement that
transfers, in whole or in part, the economic risk of ownership of the Common
Stock, for a period of 180 days from the date of this Prospectus, without the
prior written consent of DLJ. In addition, during such period, the Company has
also agreed not to file any registration agreement with respect to the
registration of any shares of Common Stock or any securities convertible into or
exchangeable for Common Stock without DLJ's prior written consent. The
stockholders of the Company, pursuant to the lock-up provisions of stock
purchase agreements to which they and the Company are a party, and the
optionholders of
    
 
                                       55

the Company, pursuant to agreements with the Company which they must sign upon
exercise of their options, have also agreed or will agree, as the case may be,
not to sell, make any short sale of, loan, grant any option for the purchase of,
or otherwise dispose of their shares of Common Stock for a period of 180 days
from the date of this Prospectus, without the prior written consent of DLJ.
    
 
     Prior to this offering, there has been no established trading market for
the Common Stock. The initial public offering price for the shares of Common
Stock will be determined by negotiations among the Company and the
Representatives. The factors to be considered in determining the initial public
offering price include the history of and the prospects for the industry in
which the Company competes, the past and present operations of the Company, the
historical results of operations of the Company, the prospects for future
earnings of the Company, the recent market prices of securities of generally
comparable companies and the general condition of the securities markets at the
time of the offering.
 
   
     The Common Stock has been approved for quotation on the Nasdaq National
Market, subject to notice of issuance, under the symbol "NANX."
    
 
     Other than in the United States, no action has been taken by the Company or
the Underwriters that would permit a public offering of the shares of Common
Stock offered hereby in any jurisdiction where action for that purpose is
required. The shares of Common Stock offered hereby may not be offered or sold,
directly or indirectly, nor may this Prospectus or any other offering material
or advertisements in connection with the offer and sale of any such shares of
Common Stock be distributed or published, in any jurisdiction, except under
circumstances that will result in compliance with the applicable rules and
regulations of such jurisdiction. Persons into whose possession this Prospectus
comes are advised to inform themselves about and to observe any restrictions
relating to the offering of the Common Stock and the distribution of this
Prospectus. This Prospectus does not constitute an offer to sell or a
solicitation of an offer to buy any shares of Common Stock offered hereby in any
jurisdiction in which such an offer or a solicitation is unlawful.
 
     In connection with this offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Stock. Specifically, the Underwriters may overallot the offering,
creating a syndicate short position. The Underwriters may bid for and purchase
shares of Common Stock in the open market to cover such syndicate short position
or to stabilize the price of the Common Stock. In addition, the underwriting
syndicate may reclaim selling concessions from syndicate members and selected
dealers if they repurchase previously distributed Common Stock in syndicate
covering transactions, in stabilizing transactions or otherwise. These
activities may stabilize or maintain the market price of the Common Stock above
independent market levels. The Underwriters are not required to engage in these
activities, and may end any of these activities at any time.
 
     Certain employees of DLJ own an aggregate of 97,272 shares of the Series F
Preferred, which shares will be converted into shares of Common Stock upon
consummation of this offering. None of the shares of Common Stock held by the
DLJ employees are being offered hereby.
 
                                 LEGAL MATTERS

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Nanophase Technologies Corporation
 
   
     We have audited the accompanying balance sheets of Nanophase Technologies
Corporation as of December 31, 1995 and 1996 and September 30, 1997, and the
related statements of operations, stockholders' equity, and cash flows for the
each of the three years in the period ended December 31, 1996 and for the nine
month period ended September 30, 1997. 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 audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Nanophase Technologies
Corporation at December 31, 1995 and 1996 and September 30, 1997, and the
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1996 and for the nine month period ended September 30,
1997, in conformity with generally accepted accounting principles.

  (INFORMATION WITH RESPECT TO THE NINE MONTH PERIOD ENDED SEPTEMBER 30, 1996
    
   
                     AND ALL PRO FORMA DATA ARE UNAUDITED)
    
 
(1) DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
 
     Nanophase Technologies Corporation (the "Company") was incorporated on
November 30, 1989, for the purpose of developing nanocrystalline materials for
commercial production and sale in domestic and international markets. The
Company was in its development stage for the period from inception through
December 31, 1996, primarily engaged in research and development activities, the
recruiting of technical, marketing and administrative personnel, and the
development of its manufacturing facility. These activities have been funded
through the issuance of preferred stock and through cooperative development
agreements and government contracts and grants. Although commercial shipments
began in late 1995 and continued in 1996, these shipments were limited and
primarily related to cooperative development agreements. The Company began
full-scale production in early 1997 at which time it no longer was a development
stage company.
 
     In the course of its corporate development, the Company has experienced net
losses and negative cash flows from operations. Historically, the Company has
funded its operations primarily through the issuance of equity securities.
 
   
     Export sales approximated $10,300, $51,400 and $256,500 for the years ended
December 31, 1994, 1995 and 1996, respectively and $68,600 and $277,400 for the
nine months ended September 30, 1996 and 1997, respectively.
    
 
  Basis of Presentation
 
   
     The financial statements of the Company as of September 30, 1996 and for
the nine month period ended September 30, 1996 contain all adjustments and
accruals (consisting only of normal recurring adjustments) which, in the opinion
of management, are necessary for a fair presentation of the financial position
and operating results of the Company for the interim period presented.
    
 
  Pro Forma Presentation (Unaudited)
 
   
     The pro forma balance sheet at September 30, 1997 gives effect to
conversion of the convertible preferred stock into common stock which will take
place upon the closing of the proposed public offering of common stock and the
change in the par value of the common stock, both as described in Note 11.
    
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Cash Equivalents
 
     Cash equivalents primarily consist of money market accounts which have a
maturity of three months or less from the date of purchase.
 
  Investments
 
     Investments are classified by the Company at the time of purchase for
appropriate designation and such designation is reevaluated as of each balance
sheet date. Investments are classified as held-to-maturity when the Company has
the positive intent and ability to hold the securities to maturity.
Held-to-maturity securities are stated at amortized cost and are adjusted to
maturity for the amortization of premiums and accretion of discounts. Such
adjustments for amortization and accretion are included in interest income.
 
  Inventory
 
     Inventory is stated at the lower of cost, maintained on a first in, first
out basis, or market.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Equipment and Leasehold Improvements
 
     Equipment is stated at cost and is being depreciated over its estimated
useful life (5-7 years) using the straight-line method. Leasehold improvements
are stated at cost and are being amortized using the straight-line method over
the shorter of the useful life of the asset or the term of the lease.
 
  Deferred Offering Costs
 
   
     Deferred costs related to the Company's proposed public offering totaled
$79,122 and $125,673 at December 31, 1996 and September 30, 1997, respectively.
In May 1997, the Company withdrew its March 1997 filing made with the Securities
and Exchange Commission. Costs incurred relating to that filing aggregating
$375,103 were expensed by the Company and included in selling, general and
administrative expense. Costs deferred at September 30, 1997 relate to the
current filing. Upon successful completion of the Company's proposed public
offering, the deferred costs will be offset against the proceeds received and
charged to stockholders' equity.
    
 
  Patent Costs
 
     Patent costs are being amortized over the life of the respective patent
using the straight-line method.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Commercial Revenue
 
     Commercial revenue consists of sales of product and revenue from research
and development arrangements with non-governmental entities. Sales of product
are recorded as shipments are made by the Company. Research and development
arrangements include both cost-plus and fixed fee agreements and such revenue is
recognized when specific milestones are met under the arrangements.
 
  Government Research Contracts
 
   
     The Company accounts for contracts with governmental entities to complete
research and development activities using the percentage of completion method
measured by the relationship of costs incurred to total estimated costs. Amounts
paid to the Company under its cooperative cost-sharing agreement with the U.S.
government are accounted for as offsets against cost of revenues. See Note 8.
    
 
     All payments to the Company for work performed on contracts and agreements
with agencies of the U.S. government are subject to adjustment upon audit by
agencies of the U.S. government. The Company believes that such audits, if any,
will not have a significant effect on the financial position or results of
operation of the Company.
 
  Research and Development Expenses
 
     Expenditures for research and development activities are charged to
operations as incurred by the Company.
 
  Income Taxes
 
     The Company accounts for income taxes using the liability method. As such,
deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for
 
                                       F-8

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
financial reporting purposes and the amounts used for income tax purposes.
Deferred tax assets and liabilities are calculated using the enacted tax rates
and laws that are expected to be in effect when the anticipated reversal of
these differences is scheduled to occur.
 
  Employee Stock Options
 
   
     The Company accounts for stock options granted to employees in accordance
with APB Opinion No. 25, "Accounting for Stock Issued to Employees" (APB No.
25). The exercise price of the options granted equals the estimated fair value
of the underlying stock on the date of grant. As such, no compensation expense
has been recognized by the Company for these options. In October 1995, the
Financial Accounting Standards Board issued Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" (FASB No. 123).
FASB No. 123, which was adopted by the Company in 1996, establishes an
alternative method of accounting for stock-based compensation plans. In 1996,
the Company adopted the disclosure alternative for stock-based compensation
(Note 12) which provides for the use of APB No. 25 for financial statement
purposes with pro forma disclosure of the impact of FASB No. 123.
    
 
  Fair Value of Financial Instruments
 
     The Company's financial instruments include investments, accounts
receivable, accounts payable and accrued liabilities. The fair values of all
financial instruments were not materially different from their carrying values.
 
  Net Loss and Pro Forma Net Loss Per Common Share
 
     Pro forma net loss per common share and historical net loss per common
share are computed based upon the weighted average number of common shares
outstanding. Common equivalent shares are not included in the pro forma and
historical per share calculations since the effect of their inclusion would be
anti-dilutive, except that common and common equivalent shares issued during the
twelve month period prior to the proposed public offering have been included in
the pro forma calculation as if they were outstanding for all periods presented
using the treasury stock method. In addition, for the pro forma calculation, all
convertible preferred stock is treated as if converted into common shares at
date of issuance.
 
   
     Net loss per common share computed on a historical basis is as follows:
$2.32, $3.54 and $10.06 for the years ended December 31, 1994, 1995 and 1996,
respectively, and $7.61 and $5.96 for the nine month periods ended September 30,
1996 and 1997, respectively. The weighted average number of common shares
outstanding used to calculate these net loss per common share amounts are
554,298 for all periods.
    
 
(3) INVESTMENTS
 
   
     Investments consist of U.S. Treasury bills with an estimated fair value of
$2,221,000, $1,998,000 and $2,001,000 at December 31, 1995 and 1996 and
September 30, 1997, respectively. All investments have been classified as
held-to-maturity and mature in subsequent year.
    
 
(4) INVENTORIES
 
     Inventories consist of the following:

(8) RESEARCH AND DEVELOPMENT AGREEMENTS
 
     In July 1992, the Company entered into a cooperative cost-sharing agreement
with the U.S. Government under the Department of Commerce Advanced Technology
Program. The three-year agreement ended in 1995. Under the terms of the
agreement, the U.S. Government agreed to share costs of the Company's research
efforts up to an aggregate of $944,259, including subcontractor costs. The net

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
the total research effort amounted to $2,992,130. The difference between these
amounts represented indirect costs of $2,047,871 which were absorbed as
operating expenses by the Company. For the years ended December 31, 1994 and
1995, the Company offset amounts received from the U.S. government of $224,256
and $154,710, respectively, against cost of revenues in the statement of
operations.
 
   
     The Company is party to a number of other research and development
arrangements with both governmental and commercial entities. These arrangements
are generally short-term in nature and provided $31,144, $54,680 and $236,019 of
revenues for the years ended December 31, 1994, 1995, and 1996, respectively,
and $148,927 and $1,395,077 of revenues for the nine month periods ended
September 30, 1996 and 1997, respectively. These arrangements include both
cost-plus and fixed-price agreements.
    
 
(9) PATENT LICENSE AGREEMENT
 
   
     In 1991, the Company was granted an exclusive license by a third party to
make, have made, use and sell products of the type claimed in a U.S. patent. In
consideration for this license, the Company agreed to pay royalties of 1/2% of
net sales of licensed products, as defined. As of September 30, 1997, no royalty
payments were due under this agreement.
    
 
   
     In 1994, the Company was granted a non-exclusive license by a third party
to make, use, and sell products of the type claimed in two U.S. patents. In
consideration for this license, the Company agreed to pay royalties of 1% of net
sales, as defined, and made an advance royalty payment of $17,500. As of
September 30, 1997, royalties under this agreement amounting to $11,289 have
been offset against the royalty advance.
    
 
   
     In 1996, the Company was granted a non-exclusive license by a third party
to produce and sell ultrafine powders of metal and ceramics claimed in four U.S.
patents. In consideration for this license, the Company agreed to pay $14,000 as
an initial payment, and pay royalties of 3% of net proceeds of sales of the
product, as defined. As of September 30, 1997, royalties under this agreement
approximated $8,000. The Company was also granted a remainder-exclusive license
by a third party to make, have made, use, import, sell or have sold products of
the type claimed in three U.S. patents. In consideration for this license, the
Company agreed to pay $5,000 as an initial payment, $5,000 upon reaching the
earlier of either defined profitability or the second anniversary of the
agreement, and royalties at the rate of 4% of the defined net sales of the
related products. As of September 30, 1997, no royalty payments were due to this
party under this agreement.
    
 
(10) INCOME TAXES
 
   
     The Company has net operating loss carryforwards for tax purposes of

     The valuation allowance increased $2,081,000 and $1,249,000 for the year
ended December 31, 1996 and nine months ended September 30, 1997, respectively,
due principally to the increase in the net operating loss carryforward and
uncertainty as to whether future taxable income will be generated prior to the
expiration of the carryforward period. Under the Internal Revenue Code, certain
ownership changes, including the prior issuance of preferred stock and this
proposed public offering, may subject the Company to annual limitations on the
utilization of its net operating loss carryforward.
    
 
(11) CAPITAL STOCK
 
   
     All capital share and per share amounts in the financial statements and
notes to financial statements have been restated to reflect a .579-for-1 reverse
stock split effective prior to consummation of this proposed public offering.
Additionally, the par value has been restated to $0.01 for all common stock. The
Board of Directors has approved a migratory merger of the Company from Illinois
to Delaware, pursuant to which the stock split and restated par value will
occur.
    
 
   
     In 1997, a total of 748,089 shares of Series F convertible preferred stock

</TABLE>
    
 
   
     At September 30, 1997, options for 209,183, 75,270, 62,903 and 13,896
shares of common stock were exercisable at $.112, $.432, $1.727 and $3.886 per
share, respectively. No options have been exercised or have expired to date.
    
 
   
     In connection with the issuance of Series C convertible preferred stock in
1993, the Company issued common stock purchase warrants for 662,287 shares at no
additional cost to the Series C convertible preferred stockholders. These
warrants have an exercise price of $1.123 per share and expire upon the tenth
anniversary of issuance. All warrants were outstanding at September 30, 1997.
    
 
   
     The Company has elected to follow APB No. 25 and related interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under FASB No. 123 requires use
of option valuation models that were not developed for the use in valuing
employee stock options. Pro forma information regarding net income is required
by FASB No. 123, which also requires that the information be determined as if
the Company had accounted for the employee stock options granted subsequent to
December 31, 1994 under the fair value method of that Statement. The fair value
for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions for the
years ended December 31, 1995 and 1996 and the nine month periods ended
September 30, 1996 and 1997, respectively: risk-free interest rates of 4.5%,
4.0%, 4.5% and 4.4%; a dividend yield of zero percent; and a weighted-average
expected life of the option of 7 years. The volatility factor was assumed to be
zero as the Company is privately held and no market existed for its stock in
1995 or 1996.
    
 
     The Black-Scholes option valuation model was developed for the use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's option, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     For purposes of the pro forma disclosures, the estimated fair value of the
options is amortized to expense over the vesting period of the respective
option. Because FASB No. 123 is applicable only to options granted subsequent to
December 31, 1994, its pro forma impact will not be fully reflected until 2002.
The Company's pro forma net loss and pro forma net loss per share on a
historical basis would be $1,963,974 and $5,607,688 and $3.54 and $10.12 for the
years ended December 31, 1995 and 1996 and would be $4,237,286 and $3,401,643
and $7.64 and $6.14 for the nine months ended September 30, 1996 and 1997,
respectively.
    
 
(13) 401(K) PROFIT-SHARING PLAN
 
     Effective June 30, 1995, the Company implemented a 401(k) profit-sharing
plan covering substantially all employees who meet defined service requirements.
The plan provides for deferred salary contributions by the plan participants and
a Company contribution. Company contributions, if any, are at the discretion of
the Board of Directors and are not to exceed the amount deductible under
applicable income tax laws. No Company contributions have been made since
inception of the plan.
 
(14) SEVERANCE BENEFITS AGREEMENT
 
   
     Pursuant to an agreement entered into in 1994, the Company has established
a trust for the benefit of an employee. Interest earned was credited to the
trust until the funds held in trust equaled $80,000. Payments will be required
in the event the Company terminates the employment of the individual, as
defined, before November 15, 1999. Upon the occurrence of an initial public
offering, the funds held in trust will revert to the Company.
    
 
(15) RELATED PARTY TRANSACTIONS
 
   
     The Company has an ongoing consulting agreement with a
director/stockholder. The agreement is on a month-to-month basis. Payments under
    
   
this agreement amount to $2,500 per month.

     In contrast to nanocrystalline materials produced by conventional
processes, nanocrystalline materials produced by the Company's patented PVS
process are nearly spherical and uniformly small. As a result of these and other
properties, the Company is able to engineer the attributes, including strength,
flexibility, color and electronic conductivity, of materials to yield products
that are superior to conventional materials and to establish new standards for a
range of high-performance commercial applications.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Upon the Registrant's reincorporation in Delaware, Article VII of the
Registrant's Certificate of Incorporation will provide that the Registrant shall
indemnify its directors to the full extent permitted by the General Corporation
Law of the State of Delaware and may indemnify its officers and employees to
such extent, except that the Registrant shall not be obligated to indemnify any
such person (i) with respect to proceedings, claims or actions initiated or
brought voluntarily by any such person and not by way of defense, or (ii) for
any amounts paid in settlement of an action indemnified against by the
Registrant without the prior written consent of the Registrant. Prior to
consummation of this offering, the Registrant will enter into indemnity
agreements with each of its directors. These agreements may require the
Registrant, among other things, to indemnify such directors against certain
liabilities that may arise by reason of their status or service as directors, to
advance expenses to them as they are incurred, provided that they undertake to
repay the amount advanced if it is ultimately determined by a court that they
are not entitled to indemnification, and to obtain directors' liability
insurance if available on reasonable terms.
 
     In addition, Article VII of the Registrant's Certificate of Incorporation
will also provide that a director of the Registrant shall not be personally
liable to the Registrant or its stockholders for monetary damages for breach of
his or her fiduciary duty as a director, except for liability (i) for any breach
of the director's duty of loyalty to the Registrant or its stockholders, (ii)
for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) for willful or negligent conduct in paying
dividends or repurchasing stock out of other than lawfully available funds or
(iv) for any transaction from which the director derives an improper personal
benefit.
 
     Reference is made to Section 145 of the General Corporation Law of the
State of Delaware which provides for indemnification of directors and officers
in certain circumstances.

<PAGE>   77
 
     Prior to the consummation of this offering, the Registrant intends to
purchase a directors' and officers' liability insurance policy.
 
     Under the terms of the Underwriting Agreement, the Underwriters have agreed
to indemnify, under certain conditions, the Registrant, its directors, certain
of its officers and persons who control the Company within the meaning of the
Securities Act of 1933, as amended (the "Securities Act"), against certain
liabilities.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     The following information reflects a 0.579-for-one stock split which will

shares of Series E Convertible Preferred Stock (the "Series E Preferred") at
$3.886 per share to 122 investors, which included various individuals, trusts,

of $7,468,135.
    
 
   
     In June 1997, the Registrant issued 421,992 shares of Series F Convertible

     The sales of shares of Series D Preferred, Series E Preferred and Series F
Preferred are claimed to be exempt from registration with the Securities and
Exchange Commission pursuant to Section 4(2) of the Securities Act, and/or
Regulation D promulgated thereunder as transactions by an issuer not involving
any public offering, in that the transactions involved the issuance and sale by
the Company of its securities to financially sophisticated institutions or
individuals who represented that they were aware of the Company's activities as
well as its business and financial condition, and who took such securities for
investment purposes and understood the ramifications of the same. Each security
holder represented that they acquired such securities for investment for their
own account and not for distribution. All certificates representing the
securities issued in these transactions have been legended.

ITEM 17. UNDERTAKINGS
 
     The Registrant hereby undertakes:
 
          (1) To provide to the Underwriters at the closing specified in the
     underwriting agreement, certificates in such denominations and registered
     in such names as required by the Underwriters to permit prompt delivery to
     each purchaser.
 
          (2) Insofar as indemnification for liabilities arising under the
     Securities Act may be permitted to directors, officers and controlling
     persons of the Registrant pursuant to the foregoing provisions, or
     otherwise, the Registrant has been advised that, in the opinion of the
     Securities and Exchange Commission, such indemnification is against public
     policy as expressed in the Securities Act and is, therefore, unenforceable.
     In the event that a claim for indemnification against such liabilities
     (other than the payment by the Registrant of expenses incurred or paid by a
     director, officer or controlling person of the Registrant in the successful
     defense of any action, suit or proceeding) is asserted by such director,
     officer or controlling person in connection with the securities being
     registered, the Registrant will, unless in the opinion of its counsel the
     matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by it is
     against public policy as expressed in the Securities Act and will be
     governed by the final adjudication of such issue.
 
          (3) For purposes of determining any liability under the Securities
     Act, (i) the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective and (ii)
     each post-effective amendment that contains a form of prospectus shall be
     deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

DONALDSON, LUFKIN & JENRETTE
     SECURITIES CORPORATION
FURMAN SELZ LLC
CIBC OPPENHEIMER CORP.
     As representatives of the
     several Underwriters
     named in Schedule I hereto
     c/o Donaldson, Lufkin & Jenrette
       Securities Corporation
       277 Park Avenue
       New York, New York 10172

Dear Sirs:

     Nanophase Technologies Corporation, a Delaware corporation (the
"COMPANY"), proposes to issue and sell 5,000,000 shares of its Common Stock,
$.01 par value (the "FIRM SHARES"), to the several underwriters named in
Schedule I hereto (the "UNDERWRITERS").   The Company also proposes to issue
and sell to the several Underwriters not more than an additional 750,000 shares
of its Common Stock, $.01 par value (the "ADDITIONAL SHARES"), if requested by
the Underwriters as provided in Section 2 hereof.   The Firm Shares and the
Additional Shares are hereinafter referred to collectively as the "SHARES". The







<PAGE>   2




shares of common stock of the Company to be outstanding after giving effect to
the sales contemplated hereby are hereinafter referred to as the "COMMON
STOCK".

     SECTION 1.  Registration Statement and Prospectus.  The Company has
prepared and filed with the Securities and Exchange Commission (the
"COMMISSION")  in accordance with the provisions of the Securities Act of 1933,
as amended, and the rules and regulations of the Commission thereunder
(collectively, the "ACT"), a registration statement on Form S-1 (File No.
333-36937), including a form of prospectus subject to completion, relating to
the Shares.  The registration statement, as amended at the time it became
effective, including the information (if any) deemed to be part of the
registration statement at the time of effectiveness pursuant to Rule 430A under
the Act, is hereinafter referred to as the "REGISTRATION STATEMENT"; and the
prospectus in the form first used to confirm sales of Shares is hereinafter
referred to as the "PROSPECTUS".  If the Company has filed or is required
pursuant to the terms hereof to file a registration statement pursuant to Rule
462(b) under the Act registering additional shares of Common Stock (a "RULE
462(b) REGISTRATION STATEMENT"), then, unless otherwise specified, any
reference herein to the term "Registration Statement" shall be deemed to
include such Rule 462(b) Registration Statement.

     SECTION 2.  Agreements to Sell and Purchase and Lock-Up Agreements.  On
the basis of the representations and warranties contained in this Agreement,
and subject to its terms and conditions, the Company agrees to issue and sell
to each Underwriter, and each Underwriter agrees, severally and not jointly, to
purchase from the Company at a price per Share of $______ (the "PURCHASE
PRICE") the number of Firm Shares set forth opposite the name of such
Underwriter in Schedule I hereto.

     On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to issue
and sell to the Underwriters the Additional Shares and the Underwriters shall
have the right to purchase, severally and not jointly, up to 750,000 Additional
Shares from the Company at the Purchase Price.   Additional Shares may be
purchased solely for the purpose of covering over-allotments made in connection
with the offering of the Firm Shares.   The Underwriters may exercise their
right to purchase Additional Shares in whole or in part from time to time by
giving written notice thereof to the Company within 30 days after the date of
this Agreement.  You shall give any such notice on behalf of the Underwriters
and such notice shall specify the aggregate number of Additional Shares to be
purchased pursuant to such exercise and the date for payment and delivery
thereof, which date shall be a business day (i) no earlier than two business
days after such notice has been given (and, in any event, no earlier than the
Closing Date (as hereinafter defined)) and (ii) no later than ten business days
after such




                                       2


<PAGE>   3




notice has been given.   If any Additional Shares are to be purchased, each
Underwriter, severally and not jointly, agrees to purchase from the Company the
number of Additional Shares (subject to such adjustments to eliminate
fractional shares as you may determine) which bears the same proportion to the
total number of Additional Shares to be purchased from the Company as the
number of Firm Shares set forth opposite the name of such Underwriter in
Schedule I bears to the total number of Firm Shares.

     The Company hereby agrees not to (i) offer, pledge, sell, contract to
sell, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase, or otherwise transfer
or dispose of, directly or indirectly, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock or
(ii) enter into any swap or other arrangement that transfers all or a portion
of the economic consequences associated with the ownership of any Common Stock
(regardless of whether any of the transactions described in clause (i) or (ii)
is to be settled by the delivery of Common Stock, or such other securities, in
cash or otherwise) for a period of 180 days after the date of the Prospectus
without the prior written consent of Donaldson, Lufkin & Jenrette Securities
Corporation, except (a) pursuant to this Agreement, (b) pursuant to the
preferred stock conversion to be completed upon the Closing Date, (c) for the 
Company's grant of stock options or issuance of Common Stock pursuant to the
exercise of stock options outstanding on the date of the Prospectus, pursuant
to the Company's 1992 Amended and Restated Stock Option Plan, as amended and as
described in the Prospectus, or (d) for the Company's issuance of Common Stock
pursuant to the exercise of warrants outstanding as of the date of the
Prospectus. Notwithstanding the foregoing, during such period (i) the Company
may grant stock options pursuant to the Company's existing stock option plan
and (ii) the Company may issue shares of Common Stock upon the exercise of an
option or warrant or the conversion of a security outstanding on the date
hereof.  The Company also agrees not to file any registration statement with
respect to any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for Common Stock for a period of 180 days after the
date of the Prospectus without the prior written consent of Donaldson, Lufkin &
Jenrette Securities Corporation.  The Company shall, prior to or concurrently
with the execution of this Agreement, deliver an agreement executed by each of
the directors and officers of the Company substantially in the form of Annex I
attached hereto.

     SECTION 3.  Terms of Public Offering.  The Company is advised by you that
the Underwriters propose (i) to make a public offering of their respective
portions of the Shares as soon after the execution and delivery of this
Agreement as in your judgment is advisable and (ii) initially to offer the

     SECTION 4.  Delivery and Payment.  Delivery to the Underwriters of and

and payment for such Additional Shares may be varied by agreement between you
and the Company.

     Certificates for the Shares shall be registered in such names and issued
in such denominations as you shall request in writing not later than two full
business days prior to the Closing Date or an Option Closing Date, as the case
may be.  Such certificates shall be made available to you for inspection not

accounts of the several Underwriters, against payment to the Company of the
Purchase Price therefor by wire transfer of Federal or other funds immediately
available in New York City.

     SECTION 5.  Agreements of the Company.  The Company agrees with you:

     (a) To advise you promptly and, if requested by you, to confirm such
advice in writing, (i) of any request by the Commission for amendments to the
Registration Statement or amendments or supplements to the Prospectus or for
additional information, (ii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement or of the
suspension of qualification of the Shares for offering or sale in any
jurisdiction, or the initiation of any proceeding for such purposes, (iii) when
any amendment to the Registration Statement becomes effective, (iv) if the
Company is required to file a Rule 462(b) Registration Statement after the
effectiveness of this Agreement, when the Rule 462(b) Registration Statement
has become effective and (v) of the happening of any event during the period
referred to in Section 5(d) below which makes any statement of a material fact
made in the Registration Statement or the Prospectus untrue or which requires
any additions to or changes in the Registration Statement or the Prospectus in
order to make the statements therein not misleading.  If at any time the
Commission shall issue any stop order



                                       4


<PAGE>   5




suspending the effectiveness of the Registration Statement, the Company will
use its best efforts to obtain the withdrawal or lifting of such order at the
earliest possible time.

     (b) To furnish to you four (4) signed copies of the Registration Statement
as first filed with the Commission and of each amendment to it, including all
exhibits, and to furnish to you and each Underwriter designated by you such
number of conformed copies of the Registration Statement as so filed and of
each amendment to it, without exhibits, as you may reasonably request.

     (c) To prepare the Prospectus, the form and substance of which shall be
satisfactory to you, and to file the Prospectus in such form with the
Commission within the applicable period specified in Rule 424(b) under the Act;
during the period specified in Section 5(d) below, not to file any further
amendment to the Registration Statement and not to make any amendment or
supplement to the Prospectus of which you shall not previously have been
advised or to which you shall reasonably object after being so advised; and,
during such period, to prepare and file with the Commission, promptly upon your
reasonable request, any amendment to the Registration Statement or amendment or
supplement to the Prospectus which may be necessary or advisable in connection
with the distribution of the Shares by you, and to use its best efforts to
cause any such amendment to the Registration Statement to become promptly
effective.

     (d) Prior to 10:00 A.M., New York City time, on the first business day
after the date of this Agreement and from time to time thereafter for such
period as in the opinion of counsel for the Underwriters a prospectus is
required by law to be delivered in connection with sales by an Underwriter or a
dealer, to furnish in New York City to each Underwriter and any dealer as many
copies of the Prospectus (and of any amendment or supplement to the Prospectus)
as such Underwriter or dealer may reasonably request.

     (e) If during the period specified in Section 5(d), any event shall occur
or condition shall exist as a result of which, in the opinion of counsel for
the Underwriters, it becomes necessary to amend or supplement the Prospectus in
order to make the statements therein, in the light of the circumstances when
the Prospectus is delivered to a purchaser, not misleading, or if, in the
opinion of counsel for the Underwriters,  it is necessary to amend or
supplement the Prospectus to comply with applicable law, forthwith to prepare
and file with the Commission an appropriate amendment or supplement to the
Prospectus so that the statements in the Prospectus, as so amended or
supplemented, will not, in the light of the circumstances when it is so
delivered, be misleading, or so that the Prospectus will comply with applicable
law, and to furnish to each Underwriter



                                       5


<PAGE>   6




and to any dealer as many copies thereof as such Underwriter or dealer may
reasonably request.

     (f) Prior to any public offering of the Shares, to cooperate with you and
counsel for the Underwriters in connection with the registration or
qualification of the Shares for offer and sale by the several Underwriters and
by dealers under the state securities or Blue Sky laws of such jurisdictions as
you may request, to continue such registration or qualification in effect so
long as required for distribution of the Shares and to file such consents to
service of process or other documents as may be necessary in order to effect

securities or Blue Sky laws of the various states, the Nasdaq National Market,  
the National Association of Securities Dealers, Inc. or Delaware or Illinois

conflict with or constitute a breach of any of the terms or provisions of, or a
default under, the charter or by-laws of the Company in effect at such time or 
any indenture, loan agreement, mortgage, lease or other agreement or instrument

     (k) There are no legal or governmental proceedings pending or threatened
to which the Company is or could be a party or to which any of its property is
or could be subject that are required to be described in the Registration
Statement or the Prospectus and are not so described; nor are there any

prospects, financial condition or results of operation of the Company.

     (m) The Company has such permits, licenses, consents, exemptions,

tribunals, including, without limitation, under any applicable Environmental
Laws, as are necessary to own, lease, license and operate its properties and to
conduct its business, except where the failure to have any such Authorization

termination of any such Authorization or results or, after notice or lapse of

of any such Authorization; and such Authorizations contain no restrictions that
are burdensome to the Company; except where such failure to be valid and in

condition or results of operations of the Company.

     (o) This Agreement has been duly authorized, executed and delivered by the
Company.

     (p) Ernst & Young LLP are independent public accountants with respect to
the Company as required by the Act.

     (r) The Company is not and, after giving effect to the offering and sale
of the Shares and the application of the proceeds thereof as described in the
Prospectus, will not be, an "investment company" as such term is defined in the
Investment Company Act of 1940, as amended.

     (s) Except as otherwise disclosed in the Prospectus, there are no
contracts, agreements or understandings between the Company and any person
granting such person the right to require the Company to file a registration
statement under the Act with respect to any securities of the Company or to

     (t) Since the respective dates as of which information is given in the
Prospectus, other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement),
(i) there has not occurred  any material adverse change or any development
involving a prospective material adverse change in the condition, financial or
otherwise, or the earnings, business, management or operations of the Company,
(ii) there has not been any material adverse change or any development
involving a prospective material adverse change in the capital stock or in the

     (u) Each certificate signed by any officer of the Company and delivered to

matters covered thereby.

confidential information, systems or procedures), trademarks, service marks and
trade names ("intellectual property") currently employed by it in connection
with the business now operated by it except where the failure to own or possess
or otherwise be able to acquire such intellectual property would not, singly or
in the aggregate, have a material adverse effect on the business, prospects,
financial condition or results of operation of the Company; and the Company has
not received any notice of infringement of or conflict with asserted rights of
others with respect to any of such intellectual property which, singly or in
the aggregate, if the subject of an unfavorable decision, ruling or finding,

     (w) The Company has good and marketable title in fee simple to all real
property and good and marketable title to all personal property owned by it
which is material to the business of the Company, in each case free and clear
of all liens, encumbrances and defects except such as are described in the
Prospectus or such as do not materially affect the value of such property and
do not interfere with the use made and proposed to be made of such property by
the Company; and any real property and buildings held under lease by the
Company are held by it under valid, subsisting and enforceable leases with such
exceptions as are not material and do not interfere with the use made and
proposed to be made of such property and buildings by the Company, in each case
except as described in the Prospectus.

     SECTION 7.  Indemnification.  (a) The Company agrees to indemnify and hold
harmless each Underwriter, its directors, its officers and each person, if any,
who controls any Underwriter within the meaning of Section 15 of the Act or
Section 20 of the Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT"), from and against any and all losses, claims, damages, liabilities and
judgments (including, without limitation, any legal or other expenses incurred
in connection with investigating or defending any matter, including any action,
that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement (or any amendment
thereto), the Prospectus (or any amendment or supplement thereto) or any
preliminary prospectus, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or judgments are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information
relating to any Underwriter furnished in writing to the Company by such
Underwriter through you expressly for use therein; provided, however, that,
with respect to any untrue statement or alleged untrue statement or omission or
alleged omission made in any preliminary prospectus, the foregoing indemnity
agreement shall not inure to the benefit of any Underwriter from whom the
person asserting any such losses, claims, damages or liabilities purchased the
Shares concerned, or any person controlling such Underwriter, to the extent
that any such loss, claim, damage or liability of such Underwriter results from
the fact that a copy of the Prospectus (or Prospectus as amended or
supplemented) was not sent or given to such person, if required by the
Securities Act so to have been delivered, at or prior to the written
confirmation of the sale of such Shares to such person and the untrue statement
or alleged untrue statement or omission or alleged omission was corrected in
such Prospectus (or Prospectus as amended or supplemented), if the Company had




                                       13


<PAGE>   14




previously furnished copies of such Prospectus (or Prospectus as amended or
supplemented) to such Underwriter.

     (b) Each Underwriter agrees, severally and not jointly, to indemnify and
hold harmless the Company, its directors, its officers who signed the
Registration Statement and each person, if any, who controls the Company within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the
same extent as the foregoing indemnity from the Company to such Underwriter but
only with reference to information relating to such Underwriter furnished in
writing to the Company by such Underwriter through you expressly for use in the
Registration Statement (or any amendment thereto), the Prospectus (or any
amendment or supplement thereto) or any preliminary prospectus.

     (c)   In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying party") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 7(a) and 7(b), the Underwriter shall not be required to assume
the defense of such action pursuant to this Section 7(c), but may employ
separate counsel and participate in the defense thereof, but the fees and
expenses of such counsel, except as provided below, shall be at the expense of
such Underwriter).   Any indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of the indemnified
party unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all indemnified parties and all such fees and
expenses shall be reimbursed as they are incurred.  Such firm shall




                                       14


<PAGE>   15




be designated in writing by Donaldson, Lufkin & Jenrette Securities
Corporation, in the case of parties indemnified pursuant to Section 7(a), and
by the Company, in the case of parties indemnified pursuant to Section 7(b).
The indemnifying party shall indemnify and hold harmless the indemnified party
from and against any and all losses, claims, damages, liabilities and judgments
by reason of any settlement of any action (i) effected with its written consent
or (ii) effected without its written consent if the settlement is entered into
more than twenty business days after the indemnifying party shall have received
a request from the indemnified party for reimbursement for the fees and
expenses of counsel (in any case where such fees and expenses are at the
expense of the indemnifying party) and, prior to the date of such settlement,
the indemnifying party shall have failed to comply with such reimbursement
request.   No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement or compromise of, or consent to
the entry of  judgment with respect to, any pending or threatened action in
respect of which the indemnified party is or could have been a party and
indemnity or contribution may be or could have been sought hereunder by the
indemnified party, unless such settlement, compromise or judgment (i)  includes
an unconditional release of the indemnified party from all liability on claims
that are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

     (d) To the extent the indemnification provided for in this Section 7 is
unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Underwriters on the other hand from the
offering of the Shares or (ii) if the allocation provided by clause 7(d)(i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause 7(d)(i) above
but also the relative fault of the Company on the one hand and the Underwriters
on the other hand in connection with the statements or omissions which resulted
in such losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations.  The relative benefits received by the
Company on the one hand and the Underwriters on the other hand shall be deemed
to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by the Company, and the total underwriting
discounts and commissions received by the Underwriters, bear to the total price
to the public of the Shares, in each case as set forth in the table on the
cover page of the Prospectus.  The relative fault of the Company on the one
hand and the Underwriters on the other hand shall be determined by reference
to,



                                       15


<PAGE>   16




among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Underwriters and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding
paragraph.  The amount paid or payable by an indemnified party as a result of
the losses, claims, damages, liabilities or judgments referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
indemnified party in connection with investigating or defending any matter,
including any action, that could have given rise to such losses, claims,
damages, liabilities or judgments.  Notwithstanding the provisions of this
Section 7, no Underwriter shall be required to contribute any amount in excess
of the amount by which the total price at which the Shares underwritten by it
and distributed to the public were offered to the public exceeds the amount of
any damages which such Underwriter has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission.  No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  The Underwriters' obligations to
contribute pursuant to this Section 7(d) are several in proportion to the
respective number of Shares purchased by each of the Underwriters hereunder and
not joint.

     (e) The remedies provided for in this Section 7 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

     SECTION 8.  Conditions of Underwriters' Obligations.  The several
obligations of the Underwriters to purchase the Firm Shares under this
Agreement are subject to the satisfaction of each of the following conditions:

     (a) All the representations and warranties of the Company contained in
this Agreement shall be true and correct on the Closing Date with the same
force and effect as if made on and as of the Closing Date.

     (b) If the Company is required to file a Rule 462(b) Registration
Statement after the effectiveness of this Agreement, such Rule 462(b)
Registration Statement shall have become effective by 10:00 P.M., New York City
time, on the



                                       16


<PAGE>   17




date of this Agreement; and no stop order suspending the effectiveness of the
Registration Statement shall have been issued and no proceedings for that
purpose shall have been commenced or shall be pending before or contemplated by
the Commission.

     (c) You shall have received on the Closing Date a certificate dated the
Closing Date, signed by Robert W. Cross and Dennis J. Nowak, in their
respective capacities as the President and Chief Executive Officer and Chief
Financial Officer and Vice President of Finance and Administration of the
Company, confirming the matters set forth in Sections 6(t), 8(a) and 8(b) and
that the Company has complied with all of the agreements and satisfied all of
the conditions herein contained and required to be complied with or satisfied
by the Company on or prior to the Closing Date.

     (d) Since the respective dates as of which information is given in the
Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement),
(i) there shall not have occurred  any change or any development involving a
prospective change in the condition, financial or otherwise, or the earnings,
business, management or operations of the Company, (ii) there shall not have
been any change or any development involving a prospective change in the
capital stock or in the long-term debt of the Company and (iii) the Company
shall not have incurred any liability or obligation, direct or contingent, the
effect of which, in any such case described in clause 8(d)(i), 8(d)(ii) or
8(d)(iii), in your judgment, is material and adverse and, in your judgment,
makes it impracticable to market the Shares on the terms and in the manner
contemplated in the Prospectus.

     (e)   You shall have received on the Closing Date an opinion (satisfactory

      other tribunals, including, without limitation, under any applicable
      Environmental Laws, as are necessary to own, lease, license and operate
      its respective properties and to conduct its business as presently
      conducted and as contemplated by the Prospectus, except where the failure

      not, singly or in the aggregate, have a material adverse effect on the
      business, prospects, financial condition or results of operations of the
      Company; (B) each such Authorization is valid and in full force and

      failure to be valid and in full force and effect or to be in compliance,

      registered pursuant to the Registration Statement, except as set forth in
      the Prospectus;

           In addition, such counsel shall state that such counsel has 
participated in conferences with officers and representatives of the
Company, the Company's independent public accountants and you and your counsel,

discussed and (A) the Registration Statement and the Prospectus and any
supplement or amendment thereto (except for the financial statements, including
the notes thereto, schedules and other financial data included therein as to
which no opinion




                                       20


<PAGE>   21




need be expressed) comply as to form with the Act, and (B) (without taking any
further action to verify independently the statements made in the Registration
Statement and the Prospectus and, except as stated in the foregoing opinion,
without assuming responsibility for the accuracy, completeness or fairness of
such statements) (i) such counsel has no reason to believe that at the time the
Registration Statement became effective or on the date of this Agreement, the
Registration Statement and the form of prospectus subject to completion
included therein (except for the financial statements, including the notes
thereto, schedules  and other financial data as to which such counsel need not
express any belief) contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading and (ii) such counsel has no reason
to believe that the Prospectus, as amended or supplemented, if applicable
(except for the financial statements, including the notes thereto, schedules
and other financial data, as aforesaid) contains any untrue statement of a
material fact or omits to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

     (f) You shall have received on the Closing Date an opinion (satisfactory
to you and counsel for the Underwriters), dated the Closing Date, of McAndrews,
Held & Malloy, Ltd., counsel for the Company, to the effect that:

           (i) To such counsel's knowledge, the Company owns or possesses, or
      can acquire on reasonable terms, all patents, patent rights, licenses,
      inventions, copyrights, know-how (including trade secrets and other
      unpatented and/or unpatentable proprietary or confidential information,
      systems or procedures), trademarks, service marks and trade names
      ("intellectual property") currently employed by them in connection with
      the business now operated by them except where the failure to own or
      possess or otherwise be able to acquire such intellectual property would
      not, singly or in the aggregate, have a material adverse effect on the
      business, prospects, financial condition or results of operation of the
      Company; and, to the best of such counsel's knowledge after due inquiry,
      the Company has not received any notice of infringement of or conflict
      with asserted rights of others with respect to any of such intellectual
      property which, singly or in the aggregate, if the subject of an
      unfavorable decision, ruling or finding, would have a material adverse
      effect on the business, prospects, financial condition or results of
      operations of the Company.

           (ii) The statements under the captions "Risk Factors--Dependence on
      Patents and Protection of Proprietary Information" and

     matters, documents or proceedings referred to therein, fairly
     present the information called for with respect to such legal 
     matters, documents and proceedings.

     The opinion of Katten Muchin & Zavis described in Section 8(e) above and
the opinion of McAndrews, Held & Malloy, Ltd. described in Section 8(f) above
shall be rendered to you at the request of the Company and shall so state
therein.

     (g) You shall have received on the Closing Date an opinion, dated the
Closing Date, of Latham & Watkins, counsel for the Underwriters, as to the
matters referred to in Sections 8(e)(iv), 8(e)(v), 8(e)(viii) (but only with
respect to the statements under the caption "Description of Capital
Stock--Certain Corporate Provisions" and "Underwriting") and the last paragraph
in Section 8(e).

     (h) You shall have received, on each of the date hereof and the Closing
Date, a letter dated the date hereof or the Closing Date, as the case may be,
in form and substance satisfactory to you, from Ernst & Young, LLP, independent
public accountants, containing the information and statements of the type
ordinarily included in accountants' "comfort letters" to Underwriters with
respect to the financial statements and certain financial information contained

     (i) The Company shall have delivered to you the agreements specified in
Section 2 hereof which agreements shall be in full force and effect on the

     SECTION 9.  Effectiveness of Agreement and Termination.  This Agreement
shall become effective upon the execution and delivery of this Agreement by the
parties hereto.

     This Agreement may be terminated at any time on or prior to the Closing
Date by you by written notice to the Company if any of the following has
occurred:  (i) any outbreak or escalation of hostilities or other national or
international calamity or crisis or change in economic conditions or in the
financial markets of the United States or elsewhere that, in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market
the Shares on the terms and in the manner contemplated in the Prospectus, (ii)
the suspension or material limitation of trading in securities or other
instruments on the New York Stock Exchange, the American Stock Exchange, the
Chicago Board of Options Exchange, the Chicago Mercantile Exchange, the Chicago
Board of Trade or the Nasdaq National Market or limitation on prices for
securities or other instruments on any such exchange or the Nasdaq National
Market, (iii) the suspension of trading of any securities of the Company on any
exchange or in the over-the-counter market, (iv) the enactment, publication,
decree or other promulgation of any federal or state statute, regulation, rule
or order of any court or other governmental authority which in your opinion
materially and adversely affects, or will materially and adversely affect, the
business, prospects, financial condition or results of operations of the
Company and its subsidiaries, taken as a whole, (v) the declaration of a
banking moratorium by either federal or New York State authorities or (vi) the
taking of any action by any federal, state or local government or agency in
respect of its monetary or fiscal affairs which in your opinion has a material
adverse effect on the financial markets in the United States.

     If on the Closing Date or on an Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase the Firm
Shares or Additional Shares, as the case may be, which it has or they have
agreed to purchase hereunder on such date and the aggregate number of Firm
Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not
more than one-tenth of the total number of Firm Shares or Additional Shares, as
the case may be, to be purchased on such date by all Underwriters, each
non-defaulting Underwriter shall be obligated severally, in the proportion
which the number of Firm Shares set forth opposite its name in Schedule I bears
to the total number of Firm Shares which all the non-defaulting Underwriters
have agreed to purchase, or in such other proportion as you may specify, to
purchase the Firm Shares or Additional Shares, as the case may be, which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
on such date; provided that in no event shall the number of Firm Shares or
Additional Shares, as the case may be, which any Underwriter has agreed to
purchase pursuant to Section 2 hereof be increased




                                       23


<PAGE>   24




pursuant to this Section 9 by an amount in excess of one-ninth of such number
of Firm Shares or Additional Shares, as the case may be, without the written
consent of such Underwriter.  If on the Closing Date any Underwriter or
Underwriters shall fail or refuse to purchase Firm Shares and the aggregate
number of Firm Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Firm Shares to be purchased  by all
Underwriters and arrangements satisfactory to you and the Company for purchase
of such Firm Shares are not made within 48 hours after such default, this
Agreement will terminate without liability on the part of any non-defaulting
Underwriter and the Company.   In any such case which does not result in
termination of this Agreement, either you or the Company shall have the right
to postpone the Closing Date, but in no event for longer than seven days, in
order that the required changes, if any, in the Registration Statement and the
Prospectus or any other documents or arrangements may be effected. If, on an
Option Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Additional  Shares and the aggregate number of Additional Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Additional Shares to be purchased on such date, the non-defaulting
Underwriters shall have the option to (i) terminate their obligation hereunder
to purchase such Additional Shares or (ii) purchase not less than the number of
Additional Shares that such non-defaulting Underwriters would have been
obligated to purchase on such date in the absence of such default.  Any action
taken under this paragraph shall not relieve any defaulting Underwriter from
liability in respect of any default of any such Underwriter under this
Agreement.

     SECTION 10.  Miscellaneous.  Notices given pursuant to any provision of
this Agreement shall be in writing via mail, overnight courier, hand delivery
or facsimile addressed as follows:  (i) if to the Company, to Nanophase
Technologies Corporation, 453 Commerce Street, Burr Ridge, Illinois  60521,

Securities Corporation, 277 Park Avenue, New York, New York 10172, Attention:

     The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company and the several Underwriters set
forth in or made pursuant to this Agreement shall remain operative and in full
force and effect, and will survive delivery of and payment for the Shares,
regardless of (i) any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the officers or directors of any
Underwriter, any person controlling any Underwriter, the Company, the officers
or directors of the




                                       24


<PAGE>   25




Company or any person controlling the Company, (ii) acceptance of the Shares
and payment for them hereunder and (iii) termination of this Agreement.

     If for any reason the Shares are not delivered by or on behalf of the
Company as provided herein (other than as a result of any termination of this
Agreement pursuant to Section 9), the Company agrees to reimburse the several
Underwriters for all reasonable out-of-pocket expenses (including the
reasonable fees and disbursements of counsel) incurred by them. Notwithstanding
any termination of this Agreement, the Company shall be liable for all expenses
which it has agreed to pay pursuant to Section 5(i) hereof.  The Company also
agrees to reimburse the several Underwriters, their directors and officers and
any persons controlling any of the Underwriters for any and all reasonable 
fees and expenses (including, without limitation, the reasonable fees and 
disbursements of counsel) incurred by them in connection with enforcing their 
rights hereunder (including, without limitation, pursuant to Section 7 hereof).

     Except as otherwise provided, this Agreement has been and is made solely
for the benefit of and shall be binding upon the Company, the Underwriters, the
Underwriters' directors and officers, any controlling persons referred to
herein, the Company's directors and the Company's officers who signed the
Registration Statement and their respective successors and assigns, all as and
to the extent provided in this Agreement, and no other person shall acquire or
have any right under or by virtue of this Agreement.  The term "successors and
assigns" shall not include a purchaser of any of the Shares from any of the
several Underwriters merely because of such purchase.

     This Agreement shall be governed and construed in accordance with the laws
of the State of New York.

     This Agreement may be signed in various counterparts which together shall
constitute one and the same instrument.

                c.  Liquidation Rights:  In the event of any liquidation,
           dissolution or winding up of the Corporation, whether voluntary or
           involuntary, after payment or provision for payment of the debts and

           which the holders of any outstanding shares of Preferred Stock or
           Old Preferred shall be entitled upon dissolution, liquidation or
           winding up, the holders of the Common Stock shall be entitled to
           share ratably in the remaining assets of the Corporation with the
           holders of any outstanding shares of Old Preferred (with each share
           of Old Preferred being treated for such purpose as equal to the
           number of shares of Common Stock into which each such share of Old
           Preferred is convertible on the date of such distribution), or, if
           no shares of Old Preferred are outstanding, such assets available

           stockholders shall be distributed ratably among the holders of the 
           shares of Common Stock.

           2.  Preferred Stock.

               Preferred Stock may be issued from time to time in one or more
     series. One series consists of 292,728 shares and is designated Series A
     Convertible Preferred Stock, no par value (herein designated "Series A

     designated Series B Convertible Preferred Stock, no par value (herein
     called "Series B Preferred").  A third series consists of 1,143,846 shares
     designated as Series C Convertible Preferred Stock, no par value (herein
     called "Series C Preferred"), and 1,143,846 shares designated as Series
     C-1 Convertible Preferred Stock, no par value (herein called "Series C-1

     limitations prescribed by law, to provide for the issuance of and to issue
     shares of the Preferred Stock in one or more series, and by filing a
     certificate pursuant to the laws of the State of Delaware, to establish
     from time to time the number of shares to be included in each such series,
     and to fix the designation, powers, preferences and rights of the shares
     of each such series and any qualifications, limitations or restrictions
     thereof.  The number of authorized shares of Preferred Stock may be
     increased or decreased (but not below the number of shares thereof then
     outstanding) by the affirmative vote of the holders of a majority of the
     Common Stock, without a vote of the holders of any Preferred Stock, or of  
     any series thereof, unless a vote of any such holders is required  
     pursuant to the certificate or certificates establishing such series of
     Preferred Stock.

     C. The designations and the powers, preferences and relative,
participating, optional or other rights of the Series A Preferred, Series B
Preferred, Series C Preferred, Series C-1 Preferred, Series D Preferred, Series
D-1 Preferred, Series E Preferred and Series F Preferred (hereinafter referred
to collectively and individually as the "Old Preferred") and the
qualifications, limitations or restrictions thereof are as follows:

     1.  Voting Rights.  Except as otherwise required by law, each share of 
outstanding Old Preferred shall entitle the holder thereof to vote on each
matter submitted to a vote of the stockholders of the Corporation and to have
the number of votes equal to the number (including any fraction) of shares of
Common Stock into which such share of Old Preferred is then convertible
pursuant to the provisions hereof at the record date for the determination of
stockholders entitled to vote on such matters or, if no such record date is
established, at the date 

                                     -3-

<PAGE>   4

such vote is taken or any written consent of stockholders becomes effective. 
Except as otherwise required by law, the holders of shares of Common
Stock and Old Preferred shall vote together and not as separate classes, and
the holders of Series A Preferred, Series B Preferred, Series C Preferred,
Series C-1 Preferred, Series D Preferred, Series D-1 Preferred, Series E
Preferred and Series F Preferred shall vote together as a single class of
Preferred Stock and not as separate series.

     2.  Dividends.

     (a)  The holders of the Series B Preferred shall be entitled to receive,
out of funds legally available therefor, and without declaration by the Board
of Directors, cumulative cash dividends in the amount of $0.052 per share per
annum (such amount to be adjusted proportionally in the event the shares of
Series B Preferred are subdivided into a greater number or combined into a
lesser number of shares).  Dividends on the Series B Preferred shall accrue and
be cumulative commencing on the date of issuance of the first shares of Series
B Preferred and will be payable to Series B Preferred stockholders of record
only upon the liquidation of the Corporation, and then only upon the prior
satisfaction by the Corporation of the liquidation preference attaching to any
share of Preferred Stock senior in liquidation preference to the Series B
Preferred pursuant to this Certificate of Incorporation.  The amount of
dividends paid on shares of Series B Preferred shall be calculated on the basis
of a 360 day year consisting of 12 thirty day months.  Dividends paid on shares
of Series B Preferred in an amount less than the total amount of such dividends
at the time accumulated and payable shall be allocated ratably among all shares
of Series B Preferred then outstanding.

     (b)  The holders of Old Preferred shall be entitled to receive, as, when
and if declared by the Board of Directors, but only out of funds legally
available therefor, cash dividends in such amounts as the Board of Directors
may determine.

     (c)  Other than with respect to dividends paid on the Series B Preferred
which represent payment of accumulated but unpaid dividends thereon payable
pursuant to and at the time stated in Section C.2(a) above, no dividends shall
be declared or paid on the shares of any series of Old Preferred for any
dividend period unless at the same time such dividend shall be declared or paid
on all shares of Old Preferred equally.

     (d)  If any dividend or other distribution payable in cash, securities or
other property (other than securities of the Corporation the issuance of which
gives rise to adjustment of the Conversion Price pursuant to Section C.4(c) of
this Article IV) is declared on the Common Stock, each holder of shares of Old
Preferred on the record date for such dividend or distribution shall be
entitled to receive on the date of payment or distribution of such dividend or
other distribution the same cash, securities or other property which such
holder would have received on such record date if such holder was the holder of
record of the number (including any fraction) of shares of Common Stock into
which the shares of Old Preferred then held by such holder are then
convertible.  No dividend which has been previously declared but unpaid 

                                     -4-

<PAGE>   5

shall be paid prior to the voluntary or involuntary liquidation, dissolution
or winding up of the Corporation pursuant to Section C.3 of this Article IV.


     3.  Liquidation Rights.  If the Corporation shall be voluntarily or
involuntarily liquidated, dissolved or wound up:

     (a) The holder of each then outstanding share of Series F Preferred, 
Series E Preferred, Series D Preferred, Series D-1 Preferred, Series C 
Preferred and Series C-1 Preferred shall be entitled to receive out of the
assets of the Corporation available for distribution to stockholders, and
before any payment or declaration and setting apart for payment of any amount
or dividend with respect to the Series B Preferred, Series A Preferred, Common
Stock or any other equity security, the amount of $3.00 per share (with respect
to the Series F Preferred), the amount of $2.25 per share (with respect to the
Series E Preferred), the amount of $.80 per share (with respect to the Series D
Preferred and Series D-1 Preferred purchased prior to October 1, 1994), $1.00
per share (with respect to the Series D Preferred and Series D-1 Preferred
purchased on or after October 1, 1994) and $0.65 per share (with respect to the
Series C Preferred and Series C-1 Preferred) (such amounts to be adjusted
proportionally in the event the shares of Series F Preferred, Series E
Preferred, Series D Preferred, Series D-1 Preferred, Series C Preferred or
Series C-1 Preferred are subdivided into a greater number or combined into a
lesser number of shares), plus all declared but unpaid dividends on such share
for each share of Series F Preferred, Series E Preferred, Series D Preferred,
Series D-1 Preferred, Series C Preferred and Series C-1 Preferred then held by
them.  The Series F Preferred, Series E Preferred, Series D Preferred, Series
D-1 Preferred, Series C Preferred and Series C-1 Preferred shall rank on a
parity with each other as to the receipt of the respective preferential amounts
for each such series upon the occurrence of such event.  If the Corporation
shall have insufficient assets and funds to pay such amounts in full to the
holders of the Series F Preferred, Series E Preferred, Series D Preferred,
Series D-1 Preferred, Series C Preferred and Series C-1 Preferred, then all
assets and funds of the Corporation legally available for distribution shall be 
distributed ratably among the holders of the Series F Preferred, Series E
Preferred, Series D Preferred, Series D-1 Preferred, Series C Preferred and
Series C-1 Preferred in proportion to the preferential amount each such holder
is otherwise entitled to receive pursuant to this subsection (a).

     (b)  Subject to the liquidation rights of the holders of the Series F
Preferred, Series E Preferred, Series D Preferred, Series D-1 Preferred, Series
C Preferred and Series C-1 Preferred set forth in Section C.3(a) above, the
holder of each then outstanding share of Series C Preferred and Series C-1
Preferred shall be entitled to receive out of the assets of the Corporation
available for distribution to stockholders, and before any payment or
declaration and setting apart for payment of any amount or dividend with
respect to the Series B Preferred, Series A Preferred, Common Stock or any
other equity security, an amount equal to $1.30 per share (such amount to be
adjusted proportionally in the event the shares of Series C Preferred and
Series C-1 Preferred are subdivided into a greater number or combined into a
lesser number of shares), plus all declared but unpaid dividends thereon.  If
the Corporation shall have 

                                     -5-

<PAGE>   6

insufficient assets and funds to pay such amounts in full to the holders of the
Series C Preferred and Series C-1 Preferred, then all assets and funds of the
Corporation legally available for distribution shall be distributed ratably
among the holders of the Series C Preferred and Series C-1 Preferred in
accordance with the number of shares of Series C Preferred and Series C-1
Preferred held by each such holder.

     (c)  Subject to the liquidation rights of the holders of the Series F
Preferred, Series E Preferred, Series D Preferred, Series D-1 Preferred, Series
C Preferred and Series C-1 Preferred set forth in Sections C.3(a) and (b)
above, the holder of each then outstanding share of Series B Preferred shall be
entitled to receive out of the assets of the Corporation available for
distribution to stockholders, and before any payment or declaration and setting
apart for payment of any amount or dividend with respect to the Series A
Preferred, Common Stock or any other equity security, an amount equal to $.65
per share (such amount to be adjusted proportionally in the event the shares of
Series B Preferred are subdivided into a greater number or combined into a
lesser number of shares), plus all accrued or declared but unpaid dividends
thereon.  If the Corporation shall have insufficient assets and funds to pay
such amounts in full to the holders of the Series B Preferred, then all assets
and funds of the Corporation legally available for distribution shall be
distributed ratably among the holders of the Series B Preferred in accordance
with the number of shares of Series B Preferred held by each such holder.

     (d)  Subject to the liquidation rights of the holders of the Series F
Preferred, Series E Preferred, Series D Preferred, Series D-1 Preferred, Series
C Preferred, Series C-1 Preferred and Series B Preferred set forth in Sections
C.3(a), (b) and (c) above, the holder of each then outstanding share of Series
A Preferred shall be entitled to receive out of the assets of the Corporation
available for distribution to stockholders, and before any payment or
declaration and setting apart for payment of any amount or dividend with
respect to the Common Stock or any other equity security, an amount equal to
$2.05 per share (such amount to be adjusted proportionally in the event the
shares of Series A Preferred are subdivided into a greater number or combined
into a lesser number of shares), plus all declared but unpaid dividends
thereon.  If the Corporation shall have insufficient assets and funds to pay
such amounts in full to the holders of the Series A Preferred, then all assets
and funds of the Corporation legally available for distribution shall be
distributed ratably among the holders of the Series A Preferred in accordance
with the number of shares of Series A Preferred held by each such holder.

     (e)  After payment in full of the amounts payable pursuant to Sections 
C.3(a), (b), (c) and (d) above to the holders of Old Preferred, the holder of 
each then outstanding share of Series F Preferred, Series E Preferred, Series D
Preferred, Series D-1 Preferred, Series C Preferred and Series C-1 Preferred
shall be entitled to share ratably in the remaining assets of the Corporation
with the holders of Common Stock (with each share of Series F Preferred, Series
E Preferred, Series D Preferred, Series D-1 Preferred, Series C Preferred and
Series C-1 Preferred being treated, for such purpose, as equal to the number of
shares of Common Stock into which such share of Series F Preferred, Series E
Preferred, Series D Preferred, Series D-1 Preferred, Series C Preferred and
Series C-1 Preferred is convertible on the date of such distribution).

                                     -6-

     (f)  For purposes of this Section C.3, (i) any acquisition of the 
Corporation by means of a merger or other form of corporate reorganization in 
which outstanding shares of the Corporation are exchanged for securities or 
other consideration issued, or caused to be issued, by the acquiring 
corporation or its subsidiary (other than a mere reincorporation transaction),
or (ii) a sale of all or substantially all of the assets of the Corporation,
shall (for purposes of the distribution of such securities or other
consideration to the holders of Common Stock and Old Preferred) be treated as a
liquidation, dissolution or winding up of the Corporation and shall entitle the
holders of Common Stock and Old Preferred to receive at closing in cash,
securities or other property (valued as provided in Section C.3(g) below)
amounts as specified and otherwise in the order of preference as set forth in 
Sections C.3(a), (b), (c), (d) and (e) above.

     (g)  Whenever the distribution provided in this Section C.3 shall be 
payable in securities or property other than cash, the value of such 
distribution shall be the fair market value of such securities or other 
property as determined in good faith by the Board of Directors.

     4.  Conversion.

     (a)  Terms of Conversion.

          (i)  Optional Conversion.  The holder of each share of Old Preferred 
shall have the right (the "Conversion Right"), at such holder's option, to
convert such share at any time, without cost and otherwise on the terms of this
Section C.4, into the number of fully paid and non-assessable shares of Common
Stock that results from dividing the Conversion Price of the applicable series
of Old Preferred that is in effect at the time of conversion (the "Conversion
Price") into the Original Issue Price for such series of Old Preferred. The
initial Conversion Price for the Series F Preferred is $3.00 per share, for the
Series E Preferred $2.25 per share, for the Series D Preferred $.80 per share
(for shares of Series D Preferred issued prior to October 1, 1994) and $1.00
per share (for shares of Series D Preferred issued on or after October 1,
1994), for the Series C Preferred $.65 per share, for the Series B Preferred
$.65 per share, and for the Series A Preferred $2.05 per share.  The initial
conversion price for each share of the Series D-1 Preferred shall equal the
Conversion Price of the Series D Preferred from which such share of Series D-1
Preferred is converted at the time of such conversion.  The initial conversion
price for each share of the Series C-1 Preferred shall equal the Conversion
Price of the Series C Preferred from which such share of Series C-1 Preferred
is converted at the time of such conversion.  The "Original Issue Price" for
each of the Series F Preferred, Series E Preferred, Series D Preferred (for
shares of Series D Preferred issued prior to October 1, 1994), Series D-1
Preferred (issued with respect to shares of Series D Preferred issued prior to
October 1, 1994), Series D Preferred (for shares of Series D Preferred issued
on or after October 1, 1994), Series D-1 Preferred (issued with respect to
shares of Series D Preferred issued on or after October 1, 1994), Series C,
Series C-1, Series B and Series A Preferred are, respectively, $3.00, $2.25,
$1.00, $1.00, $.80, $.80, $.65, $.65, $.65 and $2.05. The Conversion Price of
each share of each series of Old Preferred shall be subject to adjustment
from time to time as provided in this Section C.4 entitled "Conversion".

                                     -7-


<PAGE>   8

          (ii)  Mandatory Conversion.  Upon the occurrence of a Qualified 
Initial Public Offering (as hereinafter defined), each share of Old Preferred 
shall be automatically converted, without cost and on the terms of this Section
C.4 entitled "Conversion", into the number of shares of Common Stock into which
such share of Old Preferred would be convertible under clause B.4(a)(i) above
immediately prior to such Qualified Initial Public Offering.

     (b)  Mechanics of Conversion.

          (i)  Optional Conversion.  A holder of any share of Old Preferred may
exercise the Conversion Right of such share by surrendering the certificate
therefor, duly endorsed, at the office of the Corporation or of any transfer
agent for the Old Preferred, together with a written notice to the Corporation
which shall state:

                  (A)  that such holder elects to convert the same,
     and;

                  (B)  the number of shares of Old Preferred being converted.

Thereupon the Corporation shall promptly issue and deliver to the holder of
such shares a certificate or certificates for the number of shares of Common
Stock to which such holder shall be entitled.  If the certificate evidencing
the Old Preferred being converted shall also evidence shares of Old Preferred
not being converted, then the Corporation shall also deliver to the holder of
such certificate a new stock certificate evidencing the Old Preferred not
converted.  The conversion of any shares of Old Preferred shall be deemed to
have been made immediately prior to the close of business on the date that the
shares of Old Preferred to be converted are surrendered to the Corporation, and
the person or persons entitled to receive the shares of Common Stock issuable
upon such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock on such date.  Any dividends or
distributions declared but unpaid at the time of conversion with respect to the
Old Preferred so converted shall be paid to the Holder of such Common Stock.
The Corporation shall give written notice to each holder of a share of Old
Preferred promptly upon the liquidation, dissolution or winding up of the
Corporation, and not more than forty (40) nor less than twenty (20) days before
the anticipated date of consummation of any acquisition of the Corporation or
any sale of all or substantially all of the assets of the Corporation referred
to in Section C.3(g) and no such acquisition of the Corporation or sale of
assets shall be effective until such notice shall have been given.

          (ii)  Mandatory Conversion.  The Corporation shall give written 
notice to each holder of a share of Old Preferred not more than forty (40) nor 
less than ten (10) days before the anticipated effective date of the 
registration statement with respect to any Qualified Initial Public Offering, 
and shall also give written notice to each such holder upon the actual 
occurrence of any Qualified Initial Public Offering.  Following the conversion 
of such shares, each holder of shares so converted may surrender the 
certificate therefor at the office of the Corporation or any transfer agent 
for the Old Preferred.  Upon such surrender, the Corporation 


                                     -8-

<PAGE>   9

shall issue and deliver to each holder a certificate or certificates for the 
number of shares  of Common Stock to which such holder is entitled.

     The conversion of shares of Old Preferred shall take place upon the
occurrence of the Qualified Initial Public Offering, whether or not the
certificates representing such shares of Old Preferred shall have been
surrendered or new certificates representing the shares of Common Stock into
which such shares have been converted shall have been issued.

     (c)  Adjustment of Conversion Price.  The Conversion Price for each share
of Old Preferred and the kind of securities issuable upon the conversion of any
share of Old Preferred shall be adjusted from time to time as follows:

          (i)  Subdivision or Combination of Shares.  If the Corporation at any
time effects a subdivision or combination of the outstanding Common Stock, each
Conversion Price shall be decreased, in the case of a subdivision, or 
increased, in the case of a combination, in the same proportions as the Common
Stock is subdivided or combined, in each case effective automatically upon, and
simultaneously with, the effectiveness of the subdivision or combination which
gives rise to the adjustment.

          (ii)  Stock Dividends.  If the Corporation at any time pays a 
dividend, or makes any other distribution, to holders of Common Stock payable 
in shares of Common Stock, or fixes a record date for the determination of 
holders of Common Stock entitled to receive a dividend or other distribution 
payable in shares of Common Stock, each Conversion Price shall be decreased by
multiplying it by a fraction:

                (A)  the numerator of which shall be the total number of shares
          of Common Stock outstanding immediately prior to such dividend or
          distribution, and

                (B)  the denominator of which shall be the total number of
          shares of Common Stock outstanding immediately after such dividend
          or distribution (plus, if the Corporation paid cash instead of
          fractional shares otherwise issuable in such dividend or
          distribution, the number of additional shares which would have been
          outstanding had the Corporation issued fractional shares instead of
          cash),

in each case effective automatically as of the date the Corporation shall take
a record of the holders of its Common Stock for the purpose of receiving such
dividend or distribution (or if no such record is taken, as of the
effectiveness of such dividend or distribution).

          (iii)  Reclassification, Consolidation or Merger.  If at any time, as
a result of:

                (A)  a capital reorganization or reclassification (other than a
          subdivision, combination or dividend which gives rise to an 
          adjustment of each Conversion

                                     -9-

<PAGE>   10

          Price pursuant to clauses (i) or (ii) of this Section C.4(c) entitled 
          "Adjustment of Conversion Price"); or

                (B)  a merger or consolidation of the Corporation with another
          corporation (whether or not the Corporation is the surviving 
          corporation),

the Common Stock issuable upon the conversion of the Old Preferred shall be
changed into or exchanged for the same or a different number of shares of any
class or classes of stock of the Corporation or any other corporation, or other
securities convertible into such shares, then, as a part of such
reorganization, reclassification, merger or consolidation, appropriate
adjustments shall be made in the terms of the Old Preferred (or of any
securities into which the Old Preferred is changed or for which the Old
Preferred is exchanged), so that:

                (Y)  the holders of Old Preferred or of such substitute
          securities shall thereafter be entitled to receive, upon conversion
          of the Old Preferred or of such substitute securities, the kind and
          amount of shares of stock, other securities, money and property
          which such holders would have received at the time of such capital
          reorganization, reclassification, merger, or consolidation, if such
          holders had converted their Old Preferred immediately prior to such
          capital reorganization, reclassification, merger, or consolidation,
          and

                (Z)  the Old Preferred or such substitute securities shall
          thereafter be adjusted on terms as nearly equivalent as may be
          practicable to the adjustments theretofore provided in this Section
          C.4(c) entitled "Adjustment of Conversion Price".

No consolidation or merger in which the Corporation is not the surviving
corporation shall be consummated unless the surviving corporation shall agree,
in writing, to the provisions of this Section C.4(c)(iii).  The provisions of
this Section C.4(c)(iii) shall similarly apply to successive capital
reorganizations, reclassifications, mergers, and consolidations.

          (iv)  Ratchet.  (A) For purposes of this Section C.4(c)(iv) entitled
"Ratchet", "Additional Shares of Common Stock" means all shares of Common Stock
sold by the Corporation after the date on which Series F Preferred has been
last issued and sold, whether or not subsequently reacquired or retired by the
Corporation, other than:

                (1) shares of Common Stock issued in transactions giving rise
          to adjustments under Sections C.4(c)(i), (ii), or (iii) above;

                (2) shares of Common Stock issued upon conversion of shares of
          Old Preferred; and

                (3) up to 4,763,440 shares of Common Stock which may be issued
          in the discretion of the Board of Directors to employees or
          directors of, or consultants 

                                    -10-

          or advisors to, the Corporation or any wholly-owned subsidiary of the
          Corporation, and options for the purchase of such shares.

          (B)  Except as otherwise provided in Section C.4(c)(v) below entitled
"Convertible Securities", if at any time the Corporation issues or is deemed to
issue Additional Shares of Common Stock for a consideration per share less than
the Conversion Price in effect with respect to any shares of the Series F
Preferred, Series E Preferred, Series D Preferred or the Series C Preferred,
respectively, at such issuance or deemed issuance,

                (1) the Conversion Price with respect to such shares of the
          Series F Preferred or Series E Preferred, as applicable, shall be
          reduced to a price per share equal to a price determined by
          dividing:

                      (y)  the sum of (1) the product derived by multiplying
                 the Conversion Price with respect to the Series F Preferred or
                 the Series E Preferred, as applicable, in effect immediately
                 prior to such issue times the number of shares of Common Stock
                 (including shares of Common Stock deemed to have been issued
                 upon conversion of the outstanding Old Preferred) outstanding
                 immediately prior to such issue, plus (2) the consideration,
                 if any, received by or deemed to have been received by the
                 Corporation upon such issue,

by:

                      (z)  the sum of (3) the number of shares of Common Stock
                 (including shares of Common Stock deemed to have been issued
                 upon conversion of the outstanding Old Preferred) outstanding
                 immediately prior to such issue, plus (4) the number of shares
                 of Common Stock issued or deemed to have been issued in such
                 issue, and

                (2) the Conversion Price with respect to such shares of the
          Series D Preferred or the Series C Preferred, as applicable, shall
          be reduced to a price per share equal to the consideration per
          share, if any, for which such Additional Shares of Common Stock are
          issued or deemed to be issued.

          (v)  Convertible Securities.

          (A)  "Convertible Securities" means all rights or options for the 
purchase of, or stock or other securities convertible into, Additional Shares 
of Common Stock or other Convertible Securities, whenever and each time issued.

          (B)  The "Effective Price" with respect to any Convertible Securities
means the result of dividing:


                                    -11-

<PAGE>   12

                (1)  the sum of (a) the total consideration, if any, received
          by the Corporation for the issuance of such Convertible Securities,
          plus (b) the minimum consideration, if any, payable to the
          Corporation upon exercise or conversion of such Convertible
          Securities, plus (c) the minimum consideration, if any, payable to
          the Corporation upon exercise or conversion of any Convertible
          Securities issuable upon exercise or conversion of such Convertible
          Securities,

by:

                (2) the maximum number of Additional Shares of Common Stock
          issuable upon exercise or conversion of such Convertible Securities
          or of any Convertible Securities issuable upon exercise or
          conversion of such Convertible Securities.

          (C)  If at any time the Corporation issues or is deemed to issue a
Convertible Security with respect to which the Effective Price is less than the
Conversion Price in effect with respect to any shares of the Series F
Preferred, Series E Preferred, Series D Preferred or the Series C Preferred,
respectively, at such issuance or deemed issuance,

                (1) the Conversion Price with respect to such shares of the
          Series F Preferred or the Series E Preferred, as applicable, shall
          be reduced to a price per share determined by dividing:

                      (y)  the sum of (1) the product derived by multiplying
                 the Conversion Price with respect to the Series F Preferred or
                 the Series E Preferred, as applicable, in effect immediately
                 prior to such issue times the number of shares of Common Stock
                 (including shares of Common Stock deemed to have been issued
                 upon conversion of the outstanding Old Preferred) outstanding
                 immediately prior to such issue, plus (2) the consideration,
                 if any, received by or deemed to have been received by the
                 Corporation upon such issue,

by:

                      (z)  the sum of (3) the number of shares of Common Stock
                 (including shares of Common Stock deemed to have been issued
                 upon conversion of the outstanding Old Preferred) outstanding
                 immediately prior to such issue, plus (4) the number of shares
                 of Common Stock issued or deemed to have been issued in such
                 issue, and

                (2) the Conversion Price with respect to such shares of the
          Series D Preferred or the Series C Preferred, as applicable, shall
          be reduced to a price per share equal to the Effective Price with
          respect to such Convertible Security, effective automatically as of
          the effectiveness of the issuance of such Convertible Security.

                                    -12-

<PAGE>   13


          (D)  If an adjustment has been made under this Section C.4(c)(v) 
entitled "Convertible Securities" as a consequence of any issuance of a 
Convertible Security, then no further adjustment shall be made under Section 
C.4(c)(iv) entitled "Ratchet" upon the actual issuance of Additional Shares of 
Common Stock upon the exercise or conversion of such Convertible Securities, or
upon the issuance of Convertible Securities issuable upon exercise or 
conversion of the original Convertible Security.

          (E)  If an adjustment has been made under this Section C.4(c)(v) 
entitled "Convertible Securities" as a consequence of any issuance of any
Convertible Security and the conversion rights, options or privileges
represented by such Convertible Security (or by any Convertible Security issued
upon exercise or conversion of the original Convertible Security) shall expire
without having been exercised, the Conversion Price with respect to the
previously affected shares of the Series F Preferred, Series E Preferred,
Series D Preferred or the Series C Preferred shall be re-adjusted as
applicable, effective upon such expiration, to eliminate the effect of the
adjustments previously made as a result of the issuance of the conversion
rights, options or privileges which shall have expired (without affecting
shares of Common Stock already issued upon the conversion of any shares of
Series F Preferred, Series E Preferred, Series D Preferred or Series C
Preferred already converted, and without affecting any other adjustments made
under this Section C.4(c)).

          (vi)  Valuation of Consideration.  For purposes of the operation of
Sections C.4(c)(iv) and (v) entitled "Ratchet" and "Convertible Securities",
respectively, the consideration received by the Corporation for any issue or
sale of securities shall:

          (A)  to the extent it consists of cash, be computed as the aggregate
amount of cash received by the Corporation;

          (B)  to the extent it consists of property other than cash, be 
computed at the fair value of that property as determined in good faith by the 
Board of Directors; and

          (C)  to the extent Additional Shares of Common Stock or Convertible
Securities are issued or sold together with other stock or securities or other
assets of the Corporation for a consideration that covers both, be such portion
of the consideration so received that may be reasonably determined in good
faith by the Board of Directors to be allocable to such Additional Shares of
Common Stock or Convertible Securities.

          (vii)  Special Mandatory Conversion.

          (A)  If (1) a holder of shares of Series D Preferred or Series C 
Preferred (for purposes of this Section C.4(c)(vii) only being treated as 
separate series, regardless of whether a holder holds shares of one or both of 
the Series D Preferred and the Series C Preferred) is entitled to exercise the
"Right Of First Refusal" set forth in Section 6 of the Amended and Restated
Shareholders' Agreement dated as of March 16, 1994, as subsequently amended,
with respect to the issuance of "New Securities" (as defined in said Agreement)
by the Corporation 

                                    -13-

<PAGE>   14

at a price per share which is less than the Conversion Price then in effect for
all or any portion of such holder's Series D Preferred and/or Series C
Preferred as applicable (the "Equity Financing"), (2) the Corporation has
complied with its obligations under the Right of First Refusal with respect to
such Equity Financing (each such Equity Financing being referred to in this
Section C.4(c)(vii) as a "Mandatory Offering"), and (c) such holder (a
"Non-Participating Holder") does not exercise such holder's Right of First
Refusal to acquire at least his "Pro Rata Share" (as defined in said
Shareholders' Agreement) offered in such Mandatory Offering, then each of such
Non-Participating Holder's shares of Series D Preferred and/or Series C
Preferred as to which the Conversion Price is greater than the price per share
paid in such Equity Financing shall automatically and without further action on
the part of such holder be converted into a share of Series D-1 Preferred or
Series C-1 Preferred respectively (a "Special Mandatory Conversion") effective
upon, subject to and concurrently with the consummation of the Mandatory
Offering (the "Mandatory Offering Date");  provided, however, that if pursuant
to the request of the Corporation the holders of Series D Preferred and Series
C Preferred are requested to purchase on a pro rata basis less than their Pro
Rata Share in connection with a particular Equity Financing, the Pro Rata Share
of each holder of Series D Preferred and Series C Preferred shall for purposes
of the application of this subsection (A) be deemed reduced to such lesser
number as the Corporation shall have requested.  Upon conversion pursuant to    
this subsection (A), the shares of Series D Preferred and Series C Preferred so
converted shall be canceled and not subject to reissuance.

          (B)  The holder of any shares of Series D Preferred or Series C 
Preferred converted pursuant to this Section C.4(c)(vii) shall deliver to the
Corporation during regular business hours at the office of the Corporation or
of any transfer agent for the Series D Preferred and Series C Preferred a
certificate or certificates for the shares of Series D Preferred and Series C
Preferred so converted, duly endorsed or assigned in blank to the Company. 
Thereafter, the Corporation shall promptly deliver to such holder a certificate
or certificates for the number of shares of Series D-1 Preferred and Series C-1
Preferred to be issued as appropriate, and such holder shall be deemed to have
become a stockholder of record on the Mandatory Offering Date, or on the
next succeeding date on which the transfer books are open.

          (C)  If any shares of Series D-1 Preferred or Series C-1 Preferred are
issued, the Corporation shall use its best efforts to take all action with
respect to such shares as may be required, including amending its Articles of
Incorporation, (1) to cancel all authorized shares of Series D-1 Preferred or
Series C-1 Preferred, as appropriate, that remain after such issuance, (2) to
create and reserve for issuance upon a subsequent Special Mandatory Conversion
of the Series D Preferred or Series C Preferred a new series of Preferred equal
in number to the number of shares of Series D-1 or Series C-1 Preferred so
canceled and designated Series D-2 Preferred or Series C-2 Preferred, with the
powers, preferences and rights and the qualifications, limitations and
restrictions identical respectively to those then applicable to the Series D-1
or Series C-1 Preferred, except that the Conversion Price for such shares of
Series D-1 Preferred or Series C-1 Preferred once initially issued shall
respectively be the Conversion Price with respect to the Series D Preferred and
Series C Preferred in effect immediately prior to such issuance, and (3) to
amend the provisions of this Section C.4(c)(vii) to provide that any 

                                    -14-

<PAGE>   15

subsequent Special Mandatory Conversion will be into shares of Series D-2
Preferred or Series C-2 Preferred, as appropriate.  The Corporation shall take
the same actions with respect to the Series D-2 Preferred and Series C-2
Preferred and each subsequently authorized series of Preferred upon initial
issuance of shares of the last such series to be authorized.

          (viii)  Other Action Affecting Common Stock.  If at any time the
Corporation takes any action affecting its Common Stock which, in the opinion
of the Board of Directors of Directors of the Corporation, would have an
adverse effect upon the Conversion Rights of the Old Preferred, the Conversion
Price and the kind of Securities issuable upon the conversion of Old Preferred
shall be adjusted in such manner and at such time as the Board of Directors of
the Corporation may in good faith determine to be equitable in the
circumstances.

          (ix)  Notice of Adjustment Events.  Whenever the Corporation 
contemplates the occurrence of an event which would give rise to adjustments
under Sections C.4(c)(i) - (v) or (viii) above, the Corporation shall mail to
each holder of Old Preferred, at least 30 days prior to the record date with
respect to such event or, if no record date shall be established, at least 30
days prior to such event, a notice specifying (A) the nature of the
contemplated event, (B) the date on which any such record is to be taken for
the purpose of such event, (C) the date on which such event is expected to
become effective, and (D) the time, if any is to be fixed, when the holders of
record of Common Stock (or other securities) shall be entitled to exchange
their shares of Common Stock (or other securities) for securities or other
property deliverable in connection with such event.

          (x)  Notice of Adjustments.  Whenever the Conversion Price or the 
kind of securities issuable upon the conversion of any one of or all of the Old
Preferred shall be adjusted pursuant to Section C.4(c)(i) - (v), (vii) or
(viii) above, the Corporation shall make a certificate signed by its President
or a Vice President and by its Chief Financial Officer, Secretary or Assistant
Secretary, setting forth, in reasonable detail, the event requiring the
adjustment, the amount of the adjustment, the method by which such adjustment
was calculated (including a description of the basis on which the Board of
Directors made any determination hereunder), and the Conversion Price and the
kind of securities issuable upon the conversion of any one of or all of the
Series A Preferred, Series B Preferred, Series C Preferred or Series C-1
Preferred after giving effect to such adjustment, and shall cause copies of
such certificate to be mailed (by first class mail postage prepaid) to each
holder of Preferred promptly after each adjustment.

          (d)  Reservation of Shares.  The Corporation will take such corporate
action as may be necessary from time to time so that at all times it will have
authorized, and reserved out of its authorized but unissued Common Stock for
the sole purpose of issuance upon conversion of shares of Old Preferred, a
sufficient number of shares of Common Stock to permit the conversion in full of
all outstanding shares of Old Preferred.

          (e)  Full Consideration.  All shares of Common Stock which shall be 
issued upon the conversion of any Old Preferred (which is itself fully paid and
non-assessable) will, upon issuance, be fully paid and non-assessable.  The
Corporation will pay such amounts and will take 

                                    -15-

<PAGE>   16

such other action as may be necessary from time to time so that all shares of
Common Stock which shall be issued upon the conversion of any Old Preferred
will, upon issuance and without cost to the recipient, be free from all
pre-emptive rights, taxes, liens and charges with respect to the issue thereof.

     (f)  Definitions. For the purpose of this Article IV, the following term
shall have the meaning ascribed below:

     "Qualified Initial Public Offering" means the consummation of the first
     issuance and sale to the public of Common Stock pursuant to an effective
     registration statement under the Securities Act of 1933 in connection with
     which (a) the price per share to the public of such securities immediately
     before such sale is not less than $3.00, as adjusted for stock splits,
     stock dividends and other similar events, (b) the price to the public of
     such securities is not less than the minimum share price necessary to
     obtain a National Market Systems listing from The Nasdaq Stock Market,
     Inc., and (c) the aggregate price to the public of the securities actually
     sold to the public in such first sale, before brokers' commissions and
     expense allowances paid by the Corporation in connection with the original
     sale of such securities, is not less than $10,000,000.

     5.  Residual Rights.  All rights accruing to the outstanding shares of the
Corporation not otherwise expressly provided for herein shall be vested in the
Common Stock.


                                   ARTICLE V

     The business and affairs of the Corporation shall be managed by or under
the direction of a board of directors consisting of not less than five (5) nor
more than nine (9) directors.  The number of directors shall be determined from
time to time by resolution adopted by the affirmative vote of a majority of the
directors in office at the time of adoption of such resolution. Initially, the
number of directors shall be five (5) and shall consist of the following
persons:  Leonard A. Batterson, Robert W. Cross, Steven Lazarus, Robert W.
Shaw, Jr. and Richard W. Siegel.

     Such directors shall be divided into three classes, Class I, Class II and
Class III; with Class I having two members, Class II having two members and
Class III having one member.  Class I shall initially consist of the following
directors:  Robert W. Cross and Robert W. Shaw, Jr.  Class II shall initially
consist of the following directors:  Steven Lazarus and Richard W. Siegel.
Class III shall initially consist of Leonard A. Batterson.  The initial term of
office of the Class I, Class II and Class III directors shall expire at the
annual meeting of stockholders in 1998, 1999 and 2000, respectively.  Beginning
in 1998, at each annual meeting of stockholders, successors to the class of
directors whose term expires at that annual meeting shall be elected for a
three-year term.  If the number of directors is changed, any increase or
decrease shall be apportioned among the classes by the Board of Directors so as
to maintain the number of directors in each class as nearly equal as is
reasonably possible, and any additional director 

                                    -16-

<PAGE>   17

of any class elected to fill a vacancy resulting from an increase in such class
shall hold office for a term that shall coincide with the remaining term of
that class.  In no case will a decrease in the number of directors shorten the
term of any incumbent director even though such decrease may result in an
inequality of the classes until the expiration of such term.  A director shall
hold office until the annual meeting of stockholders in the year in which such
director's term expires and until such director's successor shall be elected
and shall qualify, subject, however, to such director's prior death,
resignation, retirement or removal from office. Directors may only be removed
for cause, except as otherwise provided by law, by the holders of at least
sixty-six and two-thirds percent (66 2/3%) of the shares entitled to vote at an
election of directors.  Except as required by law or the provisions of this
Certificate of Incorporation, all vacancies on the Board of Directors and
newly-created directorships shall be filled by the Board of Directors.  Any
director elected to fill a vacancy not resulting from an increase in the
number of directors shall have the same remaining term as that of his or her
predecessor.

     Notwithstanding the foregoing, whenever the holders of any one or more
classes or series of Preferred Stock issued by the Corporation shall have the
right, voting separately by class or series, to elect directors at an annual or
special meeting of stockholders, the election, term of office, filling of
vacancies and other features of such directorships shall be governed by the
terms of this Certificate of Incorporation and any resolutions of the Board of
Directors applicable thereto, and such directors so elected shall not be
divided into classes pursuant to this Article V.  Notwithstanding anything to
the contrary contained in this Certificate of Incorporation, the affirmative
vote of the holders of at least eighty percent (80%) of the voting power of the
shares entitled to vote generally in the election of directors shall be
required to amend, alter or repeal, or to adopt any provision inconsistent
with, this Article V.


                                   ARTICLE VI

     The Board of Directors of the Corporation may adopt a resolution proposing
to amend, alter or repeal any provision contained in this Certificate of
Incorporation, in the manner now or hereafter prescribed by statute, and all
rights conferred upon the stockholders herein are granted subject to this
reservation.


ARTICLE VII

     A.   Indemnification of Officers and Directors:  The Corporation shall:

          1.  indemnify, to the fullest extent permitted by the DGCL, any 
     director and any officer, employee or agent of the Corporation selected by
     the Board of Directors for indemnification, such selection to be evidenced
     by an indemnification agreement, who was or is a party or is threatened to
     be made a party to any threatened, pending or completed action, suit or
     proceeding, whether civil, criminal, administrative or investigative
     (other than an action by or in the right of the Corporation) by reason of
     the 

                                    -17-

<PAGE>   18

     fact that such person is or was a director, or is or was serving at the
     request of the Corporation as a director, officer, employee or agent
     of another corporation, partnership, joint venture, trust or other
     enterprise, or if such person has previously been designated for
     indemnification by a resolution of the Board of Directors, an officer,
     employee or agent of the Corporation, against expenses (including
     attorneys' fees), judgments, fines and amounts paid in settlement actually
     and reasonably incurred by such person in connection with such action,
     suit or proceeding if such person acted in good faith and in a manner such
     person reasonably believed to be in, or not opposed to, the best interests
     of the Corporation, and, with respect to any criminal action or
     proceeding, had no reasonable cause to believe such person's conduct was
     unlawful.  The termination of any action, suit or proceeding by judgment,
     order, settlement, conviction, or upon a plea of nolo contendere or its
     equivalent, shall not, of itself, create a presumption that the person did
     not act in good faith and in a manner which such person reasonably
     believed to be in, or not opposed to, the best interests of the
     Corporation, and, with respect to any criminal action or proceeding, had
     reasonable cause to believe that such person's conduct was unlawful; and

          2.  indemnify any director and any officer, employee or agent of the
     Corporation selected by the Board of Directors for indemnification, such
     selection to be evidenced by an indemnification agreement, who was or is a
     party or is threatened to be made a party to any threatened, pending or
     completed action or suit by or in the right of the Corporation to procure
     a judgment in its favor by reason of the fact that such person is or was a
     director, or is or was serving at the request of the Corporation as a
     director, officer, employee or agent of another corporation, partnership,
     joint venture, trust or other enterprise, or if such person has previously
     been designated for indemnification by a resolution of the Board of
     Directors, an officer, employee or agent of the Corporation, against
     expenses (including attorneys' fees) actually and reasonably incurred by
     him in connection with the defense or settlement of such action or suit if
     such person acted in good faith and in a manner such person reasonably
     believed to be in or not opposed to the best interests of the Corporation
     and except that no indemnification shall be made in respect of any claim,
     issue or matter as to which such person shall have been adjudged to be
     liable to the Corporation unless and only to the extent that the Court of
     Chancery or the court in which such action or suit was brought shall
     determine upon application that, despite the adjudication of liability but
     in view of all the circumstances of the case, such person is fairly and
     reasonably entitled to indemnity for such expenses which the Court of
     Chancery or such other court shall deem proper; and

          3.  indemnify any director, officer, employee or agent against 
     expenses (including attorneys' fees) actually and reasonably incurred by 
     such person in connection therewith, to the extent that such director,
     officer, employee or agent of the Corporation has been successful on the
     merits or otherwise in defense of any action, suit or proceeding referred
     to in Article VII.A.1. and 2., or in defense of any claim, issue or
     matter therein; and


                                    -18-

<PAGE>   19

          4.  make any indemnification under Article VII.A.1. and 2. (unless
     ordered by a court) only as authorized in the specific case upon a
     determination that indemnification of the director, officer, employee or
     agent is proper in the circumstances because such director, officer,
     employee or agent has met the applicable standard of conduct set forth in
     Article VII.A.1. and 2.  Such determination shall be made (1) by the Board
     of Directors by a majority vote of a quorum consisting of directors who
     were not parties to such action, suit or proceeding, or (2) if such a
     quorum is not obtainable, or, even if obtainable a quorum of disinterested
     directors so directs, by independent legal counsel in a written opinion,
     or (3) by the stockholders of the Corporation; and

          5.  pay expenses incurred by a director or officer in defending a 
     civil or criminal action, suit or proceeding in advance of the final
     disposition of such action, suit or proceeding upon receipt of an
     undertaking by or on behalf of such director or officer to repay such
     amount if it shall ultimately be determined that such director or officer
     is not entitled to be indemnified by the Corporation as authorized in this
     Article VII.

          Notwithstanding anything to the contrary in this Article VII.A, (i)
     the Corporation shall not be obligated to indemnify a director, officer or
     employee or pay expenses incurred by a director, officer or employee with
     respect to any threatened, pending, or completed claim, suit or action,
     whether civil, criminal, administrative, investigative or otherwise
     ("Proceedings") initiated or brought voluntarily by a director, officer or
     employee and not by way of defense (other than Proceedings brought to
     establish or enforce a right to indemnification under the provisions of
     this Article VII unless a court of competent jurisdiction determines that
     each of the material assertions made by the director, officer or employee
     in such Proceedings were not made in good faith or were frivolous) and
     (ii) the Corporation shall not be obligated to indemnify a director,
     officer or employee for any amount paid in settlement of a Proceeding
     covered hereby without the prior written consent of the Corporation to
     such settlement; and

          6.  not deem the indemnification and advancement of expenses provided
     by, or granted pursuant to, the other subsections of this Article VII as
     exclusive of any other rights to which those seeking indemnification or
     advancement of expenses may be entitled under any By-law, agreement, or
     vote of stockholders or disinterested directors or otherwise, both as to
     action in such director's or officer's official capacity and as to action
     in another capacity while holding such office; and

          7.  have the right, authority and power to purchase and maintain
     insurance on behalf of any person who is or was a director, officer,
     employee or agent of the Corporation, or is or was serving at the request
     of the Corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise against
     any liability asserted against such person and incurred by such person in
     any such capacity, or arising out of such person's status as such, whether
     or not the Corporation would have the power to indemnify such person
     against such liability under the provisions of this Article VII; and


                                    -19-

<PAGE>   20

          8.  deem the provisions of this Article VII to be a contract between
     the Corporation and each director, or appropriately designated officer,
     employee or agent who serves in such capacity at any time while this
     Article VII is in effect and any repeal or modification of this Article
     VII shall not affect any rights or obligations then existing with respect
     to any state of facts then or theretofore existing or any action, suit or
     proceeding theretofore or thereafter brought or threatened based in whole
     or in part upon such state of facts.  The provisions of this Article VII
     shall not be deemed to be a contract between the Corporation and any
     directors, officers, employees or agents of any other corporation (the
     "Second Corporation") which shall merge into or consolidate with this
     Corporation when this Corporation shall be the surviving or resulting
     Corporation, and any such directors, officers, employees or agents of the
     Second Corporation shall be indemnified to the extent required under the
     DGCL only at the discretion of the board of directors of this Corporation;
     and

          9.  continue the indemnification and advancement of expenses provided
     by, or granted pursuant to, this Article VII, unless otherwise provided 
     when authorized or ratified, as to a person who has ceased to be a 
     director, officer, employee or agent of the Corporation and shall inure to
     the benefit of the heirs, executors and administrators of such a person.


     B.  Elimination of Certain Liability of Directors:  No director of the
Corporation shall be personally liable to the Corporation or its stockholders
for monetary damages for breach of fiduciary duty as a director, provided,
however, that this provision shall not eliminate or limit the liability of a
director (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
under Section 174 of the DGCL, as the same exists or may hereafter be amended,
or (iv) for any transaction from which the director derived an improper
personal benefit.  If the DGCL is amended to authorize the further elimination
or limitation of liability of directors, then the liability of a director of
the Corporation existing at the time of such elimination or limitation, in
addition to the limitation on personal liability provided herein, shall be
limited to the fullest extent permitted by the amended DGCL.  Any repeal or
modification of this Article VII by the stockholders of the Corporation shall
be prospective only, and shall not adversely affect any limitation on the
personal property of a director of the Corporation existing at the time of such
repeal or modification.


                                  ARTICLE VIII

     A director of the Corporation shall not, in the absence of fraud, be
disqualified by his office from dealing or contracting with the Corporation
either as a vendor, purchaser or otherwise, nor in the absence of fraud shall a
director of the Corporation be liable to account to the Corporation for any
profit realized by him from or through any transaction or contract of the
Corporation by reason of the fact that such director, or any firm of which such
director is 

                                    -20-

<PAGE>   21

a member or any corporation of which such director is an officer, director or
stockholder, was interested in such transaction or contract if such transaction
or contract has been authorized, approved or ratified in a manner provided in
the DGCL for authorization, approval or ratification of transactions or
contracts between the Corporation and one or more of its directors or officers
or between the Corporation and any other corporation, partnership,
association or other organization in which one or more of its directors or
officers are directors or officers or have a financial interest.


                                   ARTICLE IX

     A.  Written Consent.  At any time after the closing of a public offering of
the Corporation's Common Stock, any action required or permitted to be taken by
the stockholders of the Corporation shall be effected at a duly called annual
or special meeting of stockholders of the Corporation and shall not be effected
by any consent in writing by such stockholders pursuant to Section 228 of the
DGCL or any other provision of the DGCL.

     B.  Special Meetings.  Special meetings of stockholders of the Corporation
may be called upon not less than ten (10) nor more than sixty (60) days' written

     C.  Amendment.  Notwithstanding anything contained in this Certificate of
Incorporation to the contrary, the affirmative vote of the holders of at least
eighty percent (80%) of the shares entitled to vote generally in the election
of directors shall be required to amend, alter or repeal, or to adopt any
provision inconsistent with, this Article IX.


                                  ARTICLE X

     Meetings of stockholders may be held within or without the State of
Delaware as the By-laws of the Corporation may provide.  The books of the

Corporation or in the By-laws of the Corporation.  Election of directors need
not be by written ballot unless the By-laws of the Corporation so provide.


                                   ARTICLE XI

     Whenever a compromise or arrangement is proposed between the Corporation
and its creditors or any class of them and/or between the Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of the
Corporation or of any creditor or stockholder thereof or on the application of
any receiver or receivers appointed for the Corporation under the provisions of
Section 291 of the DGCL or on the application of trustees in dissolution or of
any receiver or

                                    -21-

<PAGE>   22

receivers appointed for the Corporation under the provisions of Section 279
of the DGCL, order a meeting of the creditors or class of creditors and/or the
stockholders or class of stock of the Corporation, as the case may be, to be
summoned in such manner as the said court directs.  If a majority in number
representing two-thirds of the value of the creditors or class of creditors
and/or the stockholders or class of stockholders of the Corporation, as the
case may be, agree to any compromise or arrangement or to any reorganization of
the Corporation as a consequence of such compromise or arrangement, said
compromise or arrangement of said reorganization shall, if sanctioned by the
Court to which said application has been made, be binding on all the creditors
or class of creditors and/or on all the stockholders or class of stockholders, 
of the Corporation, as the case may be, and also on the Corporation.


                                  ARTICLE XII

     In furtherance and not in limitation of the powers conferred by statute,
the Board of Directors is expressly authorized to adopt, alter amend or repeal

least sixty-six and two-thirds percent (66 2/3%) of the voting power of the
shares of the Corporation entitled to vote generally in the election of
directors at an annual or special meeting of stockholders, provided that if
such alteration, amendment, repeal or adoption of new By-laws is effected at a
duly called special meeting, notice of such alteration, amendment, repeal or
adoption of new By-laws is contained in the notice of such special meeting.

of the meeting or in a duly executed waiver of notice thereof.

     Section 2.2.  Time of Annual Meeting.  Annual meetings of stockholders

     Section 2.4.  Director Nominations.  Only persons who are nominated in
accordance with the following procedures shall be eligible to serve as
directors.  Nominations of persons for election to the Board of Directors of
the Corporation at a meeting of stockholders may be made (i) by or at the
direction of the Board of Directors, or (ii) by any stockholder of the
Corporation entitled to vote in the election of directors at the meeting who
complies with the notice procedures set forth in this Article II, Section 2.4.
Such nominations, other than those made by or at the direction of the Board of
Directors, shall be made pursuant to timely notice in writing to the Secretary
of the Corporation.  To be timely, a stockholder's notice must be delivered to,
or mailed and received by, the Secretary of the Corporation at the principal
executive offices of the Corporation not less than sixty (60) nor more than
ninety (90) days prior to the meeting; provided, however, that if the
Corporation has not "publicly disclosed" (in the manner provided in the last
sentence of this Article II, Section 2.4) the date of the meeting at least
seventy (70) days prior to the meeting date, notice may be timely made by a
stockholder under this Section if received by the Secretary of the Corporation
not later than the close of business on the tenth day following the day on
which the Corporation publicly disclosed the meeting date.  Such stockholder's
notice shall set forth (i) as to each person whom the stockholder proposes to
nominate for election or re-election as a director, all information relating to
such person that is required to be disclosed in solicitations of proxies for
election of directors, or is otherwise required, in each case pursuant to
Regulation 14A under the Securities Exchange Act of 1934, as amended (including
such person's written consent to being named in the proxy statement as a
nominee and to serving as director if elected); and (ii) as to the stockholder
giving notice (A) the name and address, as they appear on the Corporation's
books, of such stockholder and (B) the class and number of shares of the
Corporation which are beneficially owned by such stockholder.  At the request
of the Board of Directors, any person nominated by the Board of Directors for
election as a director shall furnish to the Secretary of the Corporation that
information required to be set forth in a stockholder's notice of nomination
which pertains to the nominee.  No person shall be eligible to serve as a
director of the Corporation unless nominated in accordance with the procedures
set forth herein.  The presiding officer shall, if the facts so warrant,
determine and declare to the meeting that a nomination was not made in
accordance with the procedures prescribed by the By-laws, and if such officer
should so determine, such officer shall so declare to the meeting and the
defective nomination shall be disregarded.  For purposes of these By-laws,
"publicly disclosed" or "public disclosure" shall mean disclosure in a press
release reported by the Dow Jones News Service, Associated Press or a
comparable national news service or in a document publicly filed by the
Corporation with the Securities and Exchange Commission.

     Section 2.5.  Annual Meeting Agenda Items.  At an annual meeting of the
stockholders, only such business shall be conducted as shall have been brought
before the meeting (i) by or at the direction of the Board of Directors, or
(ii) by any stockholder of the Corporation who complies with the notice
procedures set forth in this Article II, Section 2.5, in the time herein
provided.  For business to be properly brought before an annual meeting by a
stockholder, the stockholder must deliver written notice to, or mail such
written notice so that it is received by, the Secretary of the Corporation, at
the principal executive offices of the Corporation, not less than one hundred
twenty (120) days prior to the first anniversary of the date of the
Corporation's proxy statement released to stockholders in connection with the
previous year's annual meeting of stockholders, except that if no annual
meeting of stockholders was held in the previous year or if the date of the
annual meeting has been changed by more than thirty (30) days from the 


                                     -2-

<PAGE>   3

previous year's meeting, a proposal shall be received by the Corporation within
ten (10) days after the Corporation has "publicly disclosed" the date of the
meeting in the manner provided in Article II, Section 2.4 above.  The
stockholder's notice to the Secretary shall set forth as to each matter the
stockholder proposes to bring before the annual meeting (A) a brief description
of the business desired to be brought before the annual meeting and the reasons
for conducting such business at the annual meeting, (B) the name and address,
as they appear on the Corporation's books, of the stockholder proposing such
business, (C) the class and number of shares of the Corporation which are
beneficially owned by the stockholder and (D) any material interest of the
stockholder in such business. At an annual meeting, the presiding officer
shall, if the facts warrant, determine and declare to the meeting that business
was not properly brought before the meeting in accordance with the provisions
of this Article, Section 2.5, and if such officer should so determine, such
officer shall so declare to the meeting, and any such business not properly
brought before the meeting shall not be transacted.  Whether or not the
foregoing procedures are followed, no matter which is not a proper matter
for stockholder consideration shall be brought before the meeting.

     Section 2.6.  Special Meetings of the Stockholders.  Special meetings of
the stockholders of the Corporation may be called only by the Board of
Directors pursuant to a resolution approved by a majority of the Board of
Directors.  The business transacted at any special meeting of the stockholders
shall be limited to the purposes stated in the notice for the meeting
transmitted to stockholders.

     Section 2.7.  Notice of Special Meetings.  Written notice of a special
meeting stating the place, date and hour of the meeting and the purpose or
purposes for which the meeting is called, shall be given by the Secretary of
the Corporation not fewer than ten (10) nor more than sixty (60) days before
the date of the meeting, to each stockholder entitled to vote at such meeting.

     Section 2.8.  Fixing of Record Date.  In order that the Corporation may
determine the stockholders entitled to vote at any meeting of stockholders or
any adjournment thereof, or entitled to receive payment of any dividend or
other distribution or allotment of any rights, or entitled to exercise any
rights in respect of any change, conversion or exchange of stock or for the
purpose of any other lawful action, the Board of Directors may fix a record
date, which shall not precede the date upon which the resolution fixing the
record date is adopted, and which shall be (i) not more than sixty (60) nor
less than ten (10) days before the date of a meeting, and (ii) not more than
sixty (60) days prior to any other action.  A determination of stockholders of
record entitled to notice of or to vote at a meeting of stockholders shall
apply to any adjournment of the meeting; provided, however, that the Board of
Directors may fix a new record date for any adjourned meeting.

     Section 2.9.  Voting Lists.  The officer who has charge of the stock
ledger of the Corporation shall prepare and make, at least ten (10) days before
every meeting of stockholders, a complete list of the stockholders entitled to
vote at the meeting, arranged in alphabetical order, and showing the address of
each stockholder and the number of shares registered in the name of each
stockholder.  Such list shall be open to the examination of any stockholder,
for any purpose germane to the meeting, during ordinary business hours, for a
period of at least ten (10) days prior to the meeting, either at a place within
the city where 


                                     -3-

<PAGE>   4

the meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held. 
The list shall also be produced and kept at the time and place  of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present.

     Section 2.10.  Quorum and Adjournments.  The holders of a majority of the
voting power of the stock issued and outstanding and entitled to vote thereat,
present in person or represented by proxy, shall constitute a quorum at all
meetings of the stockholders for the transaction of business, except as
otherwise provided by statute or by the Corporation's Certificate of
Incorporation.  If, however, such quorum shall not be present or represented at
any such meeting of the stockholders, the stockholders entitled to vote
thereat, present in person or represented by proxy, shall have power to adjourn
the meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present or represented; provided that if the
adjournment is for more than thirty (30) days, or if after the adjournment a
new record date is fixed by the directors for the adjourned meeting, a new
notice shall be transmitted to the stockholders of record entitled to vote at
the adjourned meeting.  At such adjourned meeting at which a quorum shall be
present or represented, any business may be transacted which might have been
transacted at the meeting as originally notified.

     Section 2.11.  Vote Required.  When a quorum is present at any meeting of
all stockholders, the affirmative vote of the holders of a majority of the
voting power of the stock issued and outstanding and entitled to vote thereat,
present in person or represented by proxy, shall decide any question brought
before such meeting, unless the question is one upon which by express provision
of statute or of the Corporation's Certificate of Incorporation, a different
vote is required in which case such express provision shall govern and control
the decision of such question; provided, however, all elections of directors
shall be determined by a plurality of the votes cast.

     Section 2.12.  Voting Rights.  Unless otherwise provided in the
Corporation's Certificate of Incorporation, each stockholder having voting
power shall at every meeting of the stockholders be entitled to one (1) vote in
person or by proxy for each share of the capital stock having voting power held
by such stockholder, but no proxy shall be voted on after three (3) years from
its date, unless the proxy provides for a longer period.  At any meeting of the
stockholders, every stockholder entitled to vote may vote in person or by proxy
authorized by an instrument in writing or by a transmission permitted by law
filed in accordance with the procedure established for the meeting.  Any copy,
facsimile telecommunication or other reliable reproduction of the writing or
transmission created pursuant to this paragraph may be substituted or used in
lieu of the original writing or transmission for any and all purposes for which
the original writing or transmission could be used; provided that such copy,
facsimile telecommunication or other reproduction shall be a complete
reproduction of the entire original writing or transmission.  All voting,
including on the election of directors may (except where otherwise required by
law) be by a voice vote; provided, however, that upon demand therefor by a
stockholder entitled to vote or by his or her proxy, a stock vote shall be
taken.  Every stock vote shall be taken by ballots, each of which shall state
the name of the stockholder or proxy voting and such other information as may
be required under the procedure established for the meeting.  The Corporation
may, and to the extent required by law shall, in advance of any meeting of
stockholders, appoint one or more inspectors to act at the meeting and make a
written report thereof.  The Corporation may designate one or more persons as
alternate inspectors to replace any inspector who fails to act.  If no
inspector or alternate is able to act at a meeting of 

                                     -4-

<PAGE>   5

stockholders, the person presiding at the meeting may, and to the extent
required by law shall, appoint one or more inspectors to act at the meeting. 
Each inspector, before entering upon the discharge of his or her duties, shall
take and sign an oath to faithfully execute the duties of inspector with strict
impartiality and according to the best of his or her ability.  Every
vote taken by ballots shall be counted by an inspector or inspectors appointed
by the chairman of the meeting.

     Section 2.13.  Presiding Over Meetings.  The Chairman of the Board of
Directors shall preside at all meetings of the stockholders.  In the absence or
inability to act of the Chairman, the Vice Chairman, the President or a Vice
President (in that order) shall preside, and in their absence or inability to
act another person designated by one of them shall preside.  The Secretary of
the Corporation shall act as Secretary of each meeting of the stockholders.  In
the event of his or her absence or inability to act, the chairman of the
meeting shall appoint a person who need not be a stockholder to act as
Secretary of the meeting.

     Section 2.14.  Conducting Meetings.  Meetings of the stockholders shall be
conducted in a fair manner but need not be governed by any prescribed rules of
order.  The presiding officer of the meeting shall establish an agenda for the
meeting.  The presiding officer's rulings on procedural matters shall be final.
The presiding officer is authorized to impose reasonable time limits on the
remarks of individual stockholders and may take such steps as such officer may
deem necessary or appropriate to assure that the business of the meeting is
conducted in a fair and orderly manner.

     Section 3.1.  General Powers.  The business and affairs of the Corporation
shall be under the direction of and managed by, a board comprised of directors,
which may exercise all such powers of the Corporation and do all such lawful
acts and things as are not required by statute, by the Corporation's
Certificate of Incorporation or by these By-laws to be done by the
stockholders.  Directors need not be residents of the State of Delaware or
stockholders of the Corporation.  The number of directors shall be determined

otherwise provided by law, by the holders of at least 66- % of the voting power
of the shares entitled to vote at an election of directors.

     Section 3.4.  Vacancies.  Any vacancies occurring in the Board of
Directors and newly created directorships shall be filled in the manner
provided in the Corporation's Certificate of Incorporation.

     Section 3.5.  Place of Meetings.  The Board of Directors of the
Corporation may hold meetings, both regular and special, either within or
without the State of Delaware.  The first meeting of each newly elected Board
of Directors shall be held immediately following the adjournment of the annual
meeting of the stockholders at the same place as such annual meeting and no
notice of such meeting shall be necessary to the newly elected directors in
order to legally constitute the meeting, provided a quorum shall be present.
In the event such meeting is not held at such time and place, the meeting may
be held at such time and place as shall be specified in a notice given as
hereinafter provided for special meetings of the Board of Directors, or as
shall be specified in a written waiver signed by all of the directors.

     Section 3.6  Participation by Conference Telephone.  Unless otherwise
restricted by the Corporation's Certificate of Incorporation or these By-laws,
members of the Board of Directors, or any committee designated by the Board of
Directors, may participate in a meeting of the Board of Directors, or
committee, by means of conference telephone or similar communications equipment
by means of which all persons participating in the meeting can hear each other,
and participation by such means shall constitute presence in person at such
meeting.

     Section 3.7.  Regular Meetings.  Regular meetings of the Board of
Directors may be held without notice at such time and at such place as shall
from time to time be determined by the Board of Directors.

     Section 3.8.  Special Meetings.  Special meetings of the Board of
Directors may be called by the Chairman of the Board, the Chief Executive
Officer or the President on at least one day's notice to each director, either
personally, or by courier, telephone, telefax, mail or telegram.  Special
meetings shall be called by the Chairman of the Board, the Chief Executive
Officer or the President in like manner and on like notice at the written
request of one-half or more of the directors comprising the Board of Directors
stating the purpose or purposes for which such meeting is requested.  Notice of
any meeting of the Board of Directors for which a notice is required may be
waived in writing signed by the person or persons entitled to such notice,
whether before or after the time of such meeting, and such waiver shall be
equivalent to the giving of such notice.  Attendance of a director at any such
meeting shall constitute a waiver of notice thereof, except where a director
attends a meeting for the express purpose of objecting to the transaction of
any business because such meeting is not lawfully convened.  Neither the
business to be transacted at nor the purpose of any meeting of the Board of
Directors for which a notice is required need be specified in the notice, or
waiver of notice, of such meeting.  The Chairman of the Board shall preside at
all meetings of the Board of Directors.  In the absence or inability to act of
the Chairman of the Board, the Vice Chairman of the Board, the Chief Executive
Officer, the President or the Chief Financial Officer (in that order) shall

stock or series thereof and the qualifications, limitations or restrictions of

such class or series of stock; provided that, except as otherwise provided in
Section 202 of the General Corporation Law of Delaware, in lieu of the

certificate which the Corporation shall issue to represent such class or series
of stock, a statement that the Corporation will furnish without charge to each

     Section 7.2. Facsimile Signatures.  Where a certificate is countersigned
(1) by a transfer agent other than the Corporation or its employee, or (2) by a

registrar who has signed or whose facsimile signature has been placed upon a

authorizing such issue of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or such owner's legal representative, to advertise the same in
such manner as the Corporation shall require and/or give the Corporation a bond
in such sum as it may direct as indemnity against any claim that may be made
against the Corporation or its transfer agent or registrar with respect to the
certificate alleged to have been lost, stolen or destroyed.

officers, or between the Corporation and any other corporation, partnership,
association, or other organization in which one or more of its directors or
officers are directors or officers, or have a financial interest, shall be void
or voidable solely for this reason, or solely because such director or officer
is present at or participates in the meeting of the Board of Directors or
committee thereof which authorizes the contract or transaction, or solely
because such director's or officer's vote is counted for such purpose, if:

     (i)   The material facts as to such director's or officer's

           faith by vote of the stockholders; or

     (iii) The contract or transaction is fair as to the Corporation as
           of the time it is authorized, approved or ratified, by the Board of

                                November 3, 1997


Nanophase Technologies Corporation
453 Commerce Street
Burr Ridge, Illinois  60521

      RE:  REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

     We have acted as counsel for Nanophase Technologies Corporation, an
Illinois corporation which prior to consummation of the Offering (as defined
herein) will be reincorporated in Delaware (the "Company"), in connection with
the preparation and filing of a registration statement on Form S-1 (the
"Registration Statement") with the Securities and Exchange Commission under the
Securities Act of 1933, as amended.  The Registration Statement relates to the
Company's initial public offering (the "Offering") of up to 5,750,000 shares of
the Company's common stock, $.001 par value per share (the "Common Stock"),
including the 750,000 shares of Common Stock issuable upon exercise in full of
the Underwriters' (as defined herein) over-allotment option (collectively, the
"Shares").

     In connection with this opinion, we have relied as to matters of fact,
without investigation, upon certificates of public officials and others and
upon affidavits, certificates and written statements of directors, officers and
employees of, and the accountants and transfer agent for, the Company.  We have
also examined originals or copies, certified or otherwise identified to our
satisfaction, of such instruments, documents and records as we have deemed
relevant and necessary to examine for the purpose of this opinion, including
(a) the Registration Statement, as amended, (b) the Certificate of
Incorporation of the Company, (c) the By-Laws of the Company, (d) resolutions
adopted by the Board of Directors of the Company in connection with the
Offering and (e) the form of Underwriting Agreement (the "Underwriting
Agreement") between the Company and Donaldson, Lufkin & Jenrette Securities
Corporation, Furman Selz LLC and Oppenheimer & Co., Inc., as representatives of
the several underwriters (collectively, the "Underwriters").

     In connection with this opinion, we have assumed the accuracy and
completeness of all documents and records that we have reviewed, the

the Registration Statement, as amended, have sufficient legal capacity to enter
into and perform their respective obligations and to carry out their roles in
the Offering.

     Based upon and subject to the foregoing, it is our opinion that the

Shares issuable upon exercise in full of the Underwriters' over-allotment
option), when issued by the Company pursuant to the Underwriting Agreement,

the State of Delaware and the laws of the State of New York, and we do not
express any opinion concerning any other laws.  This opinion is given as of the
date hereof and we assume no obligation to advise you of changes that may
hereafter be brought to our attention.

        If an Option expires or becomes unexercisable for any reason without
having been exercised in full, the unpurchased Shares subject thereto shall
(unless this Plan shall have terminated) become available for grants of other
Options under this Plan.

        4.      Administration of Plan.

price and the obligation of any Optionee to sell purchased Shares to the Company
upon specified terms and conditions) of any Option; (x) require withholding from
or payment by an Optionee of any federal, state or local taxes; (xi) appoint and
compensate agents, counsel, auditors or other specialists as the Committee deems

        5.      Eligibility.

        (a)     Options may be granted to any Employee, Consultant or Outside
Director as the Committee may from time to time designate, provided that (i)
Incentive Stock Options may be granted only to Employees, and (ii) Options may
be granted to Outside Directors only in accordance with the provisions of
Section 5(b) below. In selecting the individuals to whom Options shall be
granted, as well as in determining the number of Options granted, the Committee
shall take into consideration such factors as it deems relevant in connection
with accomplishing the purpose of this Plan. Subject to the provisions of
Section above, an Optionee may, if he or she is otherwise eligible, be granted
an additional Option or Options if the Committee shall so determine. During any
calendar year, Options for no more than 100,000 shares of Common Stock shall be
granted to any individual Employee, Consultant or Outside Director.

        (b)     All grants of Options to Outside Directors under this Plan shall
be automatic and non-discretionary and shall be made strictly in accordance with
the following provisions:

        (i)     No person shall have any discretion to select which Outside
Directors shall be granted options or to determine the number of Shares to be
covered by options granted to Outside Directors; provided, that nothing in this
Plan shall be construed to prevent an Outside Director from declining to receive
an Option under this Plan.

        (ii)    Each Outside Director who is first elected to the Board after 
the adoption of this Plan shall be automatically granted on the date of such
election (whether by the stockholders or by the Board of Directors) an Option to
purchase 10,000 Shares (subject to adjustment as provided in Section 10 below,
following consummation of an initial public offering of the Company's
securities). On the date of the Annual Meeting of Stockholders of the Company in
each calendar year commencing with the first Annual Meeting of the Stockholders
of the Company held after the adoption of this Plan, each Outside Director who
is elected or reelected at that meeting, or whose term of office does not expire
at that meeting, shall be automatically granted an option to purchase 2,000
Shares (subject to adjustment as provided in Section 10 below, following
consummation of an initial public offering of the Company's securities);
provided that no such automatic annual grant shall be made to an Outside
Director (i) who is first elected to the Board at such Annual Meeting or was
first elected to the Board within three months prior to such Annual Meeting, or
(ii) if there are not sufficient shares remaining and available to all Outside
Directors eligible for an automatic annual grant at the time at which an
automatic annual grant would otherwise be made under this Section 5(b).

        (iii) The terms of each Option granted under this Section 5(b) shall be
as follows:

                (A) the term of the option shall be ten (10) years;

                (B) the Option shall become exercisable cumulatively with
                respect to one-third of the Shares on each of the first, second
                and third anniversaries of the date of grant; provided, however,
                that in no


                                           4


<PAGE>   5



                event shall any option be exercisable prior to obtaining
                stockholder approval of this Plan; and

                (C) the exercise price per share of Common Stock shall be 100%
                of the "Fair Market Value" (as defined in Section 7(b) below) on
                the date of grant of the Option.

        (c) Each Option granted under Section 5(b) above shall be a Nonstatutory
Stock Option. Each other Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
Notwithstanding such designations, if and to the extent that the aggregate Fair
Market Value of the Shares with respect to which Options designated as Incentive
Stock Options are exercisable for the first time by any Optionee during any
calendar year (under all plans of the Company) exceeds $100,000, such options
shall be treated as Nonstatutory Stock Options. For purposes of this Section
5(c), Options shall be taken into account in the order in which they are
granted, and the Fair Market Value of the Shares shall be determined as of the
time the Option with respect to such Shares is granted.

        (d) This Plan shall not confer upon any Optionee any right with respect
to continuation of employment by or the rendition of services to the Company or
any Parent or Subsidiary, nor shall it interfere in any way with his or her
right or the right of the Company or any Parent or Subsidiary to terminate his
or her employment or services at any time, with or without cause. The terms of
this Plan or any Options granted hereunder shall not be construed to give any
Optionee the right to any benefits not specifically provided by this Plan or in
any manner modify the Company's right to modify, amend or terminate any of its
pension or retirement plans.

        6.      Term of Plan. This Plan shall become effective upon the later to
occur of its adoption by the Board of Directors of the Company (such adoption to
include the approval of at least two Outside Directors) or its approval by vote
of the holders of a majority of the outstanding shares of the Company entitled
to vote on the adoption of this Plan, and shall terminate no later than December
31, 2007. No grants shall be made under this Plan after the date of termination
of this Plan. Any termination, either partially or wholly, shall not affect any
Options then outstanding under this Plan.

        7.      Exercise Price and Consideration.

        (a)     Exercise Price. The per Share exercise price for the Shares to 
be issued pursuant to exercise of an Option shall be determined by the Committee
as follows:

        (i)     In the case of an Incentive Stock Option granted to any 
Employee, the per Share exercise price shall be no less than 100% of the Fair
Market Value per Share on the date of grant, but if granted to an Employee who,
at the time of the grant of such Incentive Stock Option, owns stock representing
more than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the per Share exercise price shall be no
less than 110% of the Fair Market Value per Share on the date of grant.


                                           5


<PAGE>   6



        (ii)    In the case of an Incentive Stock Option granted to any person
other than an Outside Director, the per Share exercise price shall be no less
than 100% of the Fair Market Value per Share on the date of grant, but if
granted to an Employee who, at the time of the grant of such Incentive Stock
Option, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the per
Share exercise price shall be no less than 110% of the Fair Market Value per
Share on the date of grant. The exercise price of Options granted pursuant to
Section 5(b) above shall be 100% of the Fair Market Value on the date of grant
of the Option.

        For purposes of this Section 7(a), if an Option is amended to reduce the
exercise price, the date of grant of such option shall thereafter be considered
to be the date of such amendment.

        (iii) With respect to (i) or (ii) above, the per Share exercise price is
subject to adjustment as provided in Section 10 below.

        (b)     Fair Market Value. The "Fair Market Value" of the Common Stock 
shall be determined by the Committee in its discretion; provided, that if the
Common Stock is listed on a stock exchange, the Fair Market Value per Share
shall be the closing price on such exchange on the date of grant of the Option
as reported in the Wall Street Journal (or, (i) if not so reported, as otherwise
reported by the exchange, and (ii) if not reported on the date of grant, then on
the last prior date on which a sale of the Common Stock was reported); or if not
listed on an exchange but traded on the National Association of Securities
Dealers Automated Quotation National Market System ("NASDAQ"), the Fair Market
Value per Share shall be the closing price per share of the Common Stock for the
date of grant, as reported in the Wall Street Journal (or, (i) if not so
reported, as otherwise reported by NASDAQ, and (ii) if not reported on the date
of grant, then on the last prior date on which a sale of the Common Stock was
reported); or, if the Common Stock is otherwise publicly traded, the mean of the
closing bid price and asked price for the last known sale.

        (c)     Consideration. The consideration to be paid for the Shares to be
issued upon exercise of an Option, including the methods of payment described in
Section 8(b)(ii) below, shall be determined by the Committee (and in the case of
an Incentive Stock Option, shall be determined at the time of grant) to the
extent permitted under applicable laws.

        (d)     Withholding. No later than the date as of which an amount first
becomes includable in the gross income of the Optionee for Federal income tax
purposes with respect to an option, the Optionee shall pay to the Company (or
other entity identified by the Committee), or make arrangements satisfactory to
the Company or other entity identified by the Committee regarding the payment
of, any Federal, state, local or foreign taxes of any kind required by law to be
withheld with respect to such amount. Unless otherwise determined by the
Committee, withholding obligations may be settled with Common Stock, including
Common Stock underlying the subject option, provided that any applicable
requirements under Section 16 of the Exchange Act are satisfied so as to avoid


                                           6


<PAGE>   7



liability thereunder. The obligations of the Company under this Plan shall be
conditional upon such payment or arrangements, and the Company shall, to the
extent permitted by law, have the right to deduct any such taxes from any
payment otherwise due to the Optionee.

        8.      Options.

        (a)     Term of Option. The term of each Option granted (other than an
Option granted under Section 5(b) above) shall be for a period of no more than
ten (10) years from the date of grant thereof or such shorter term as may be
provided in the Option agreement. However, in the case of an Option granted to
an Optionee who, at the time the Option is granted, owns stock representing more
than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant thereof or such shorter time as may be provided in
the Option Agreement.

        (b)     Exercise of Options.

        (i)     Procedure for Exercise; Rights as a Shareholder. Any Option 
granted under this Plan (other than an Option granted pursuant to Section 5(b)
above) shall be exercisable at such times and under such conditions as
determined by the Committee, including performance criteria with respect to the
Company and/or the Optionee, and as shall otherwise be permissible under the
terms of this Plan.

        An Option may not be exercised for a fraction of a Share.

        An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may, as authorized by the Committee, consist of any
consideration and method of payment allowable under Section 7 of this Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. If the
exercise of an Option is treated in part as the exercise of an Incentive Stock
Option and in part as the exercise of a Nonstatutory Stock Option pursuant to
Section 5(b) above, the Company shall issue a separate stock certificate
evidencing the Shares treated as acquired upon exercise of an Incentive Stock
Option and a separate stock certificate evidencing the Shares treated as
acquired upon exercise of a Nonstatutory Stock Option and shall identify each
such certificate accordingly in its stock transfer records. No adjustment will
be made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in Section of this
Plan.


                                           7


<PAGE>   8




        Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be available, both for purposes of this
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

        (ii)    Method of Exercise. An Optionee may exercise an Option, in whole
or in part, at any time during the option period by the Optionee's giving
written notice of exercise on a form provided by the Committee (if available) to
the Company specifying the number of shares of Common Stock subject to the
Option to be purchased. Such notice shall be accompanied by payment in full of
the purchase price by cash or check or such other form of payment as the Company
may accept. If approved by the Committee, payment in full or in part may also be
made (A) by delivering other Shares of Common Stock which (I) either have been
owned by the Optionee for more than six (6) months on the date of surrender or
were not acquired directly or indirectly from the Company, and (II) have a Fair
Market Value on the date of surrender (determined without regard to any
limitations on transferability imposed by securities laws) equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; (B) by the execution and delivery of a note or other evidence of
indebtedness (and any security agreement thereunder) satisfactory to the
Committee; (C) by authorizing the Company to retain shares of Common Stock which
would otherwise be issuable upon exercise of the Option having a total Fair
Market Value on the date of delivery equal to the exercise price of the subject
Option; (D) by the delivery of cash by a broker-dealer to whom the Optionee has
submitted an irrevocable notice of exercise (in accordance with Part 220,
Chapter II, Title 12 of the Code of Federal Regulations, so-called "cashless"
exercise); or (E) by any combination of the foregoing. In the case of an
Incentive Stock Option, the right to make a payment in the form of already owned
shares of Common Stock of the same class as the Common Stock subject to the
Option may be authorized only at the time the Option is granted. No shares of
Common Stock shall be issued until full payment therefor has been made. An
Optionee shall have all of the rights of a shareholder of the Company holding
the class of Common Stock that is subject to such Option (including, if
applicable, the right to vote the shares and the right to receive dividends),
when the Optionee has given written notice of exercise, has paid in full for
such shares and such shares have been recorded on the Company's official
shareholder records as having been issued or transferred.

        (iii)   Termination of Status as an Employee, Consultant or Outside
Director. If an Optionee's Continuous Status as an Employee, Consultant or
Outside Director (as the case may be) is terminated for any reason whatever,
such Optionee may, but only within such period of time as provided in the Option
agreement, after the date of such termination (but in no event later than the
date of expiration of the term of such Option as set forth in the Option
agreement), exercise the Option to the extent that such Employee, Consultant or
Outside Director was entitled to exercise it at the date of such termination
pursuant to the terms of the Option agreement. To the extent that such Employee,
Consultant or Outside Director was not entitled to exercise the Option at the
date of such termination, or if such Employee, Consultant or Outside Director
does not exercise such Option (which such Employee, Consultant or Outside
Director was entitled to exercise) within the time specified in the Option
agreement, the Option shall terminate.


                                           8


<PAGE>   9



        (iv) Company Loan or Guarantee. Upon the exercise of any Option and
subject to the pertinent Option agreement and the discretion of the Committee,
the Company may at the request of the Optionee; (A) lend to the Optionee, with
recourse, an amount equal to such portion of the option exercise price as the
Committee may determine; or (B) guarantee a loan obtained by the Optionee from a
third-party for the purpose of tendering the option exercise price.

        9.      Non-transferability of Options. Except as otherwise provided in 
an Option agreement, an Option granted hereunder shall by its terms not be sold,
pledged, assigned, hypothecated, transferred, or disposed of in any manner other
than by will or the laws of descent and distribution. Except as otherwise
provided in an Option agreement, an Option may be exercised during the
Optionee's lifetime only by the Optionee.

        10.     Adjustments Upon Changes in Capitalization or Merger.

        (a)     Capitalization. Subject to any required action by the 
stockholders of the Company, the number of shares of Common Stock which have
been authorized for issuance under this Plan but as to which no Options have yet
been granted or which have been returned to this Plan upon cancellation or
expiration of an Option, and the number of shares of Common Stock subject to
each outstanding Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock of the Company or the payment of a stock
dividend with respect to the Common Stock. Except as expressly provided herein,
no issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
of Common Stock subject to an Option.

        (b)     Dissolution or Liquidation. In the event of the proposed 
dissolution or liquidation of the Company, each Option will terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Committee. The Committee may, in the exercise of its sole
discretion in such instances, declare that any Option shall terminate as of a
date fixed by the Committee and give each Optionee the right to exercise his or
her Option as to all or any part of the Optioned Stock, including Shares as to
which the Option would not otherwise be exercisable.

        (c)     Sale or Merger. "Sale" means: (i) sale (other than a sale by the
Company) of securities entitled to more than 75% of the voting power of the
Company in a single transaction or a related series of transactions; or (ii)
sale of substantially all of the assets of the Company; or (iii) approval by the
stockholders of the Company of a reorganization, merger or consolidation of the
Company, as a result of which the persons who were the stockholders of the
Company immediately prior to such reorganization, merger or consolidation do not
own securities immediately after the reorganization, merger or consolidation
entitled to more than 25% of the voting power of the reorganized, merged or
consolidated company. Immediately prior to a Sale, each Optionee may exercise
his or her Option as to all Shares then subject to the Option, regardless of any
vesting conditions


                                           9

otherwise expressed in the Option. Voting power, as used in this Section 10(c),
shall refer to those securities entitled to vote generally in the election of
directors, and securities of the Company not entitled to vote but which are
convertible into, or exercisable for, securities of the Company entitled to vote
generally in the election of directors shall be counted as if converted or
exercised, and each unit of voting securities shall be counted in proportion to
the number of votes such unit is entitled to cast.

        (d)     Purchased Shares. No adjustment under this Section 10 shall 
apply to any purchased Shares already deemed issued at the time any adjustment
would occur.

        (e)     Notice of Adjustments. Whenever the purchase price or the number
or kind of securities issuable upon the exercise of the Option shall be adjusted
pursuant to Section 10, the Company shall give each Optionee written notice
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, and the method by which such adjustment was
calculated.

        (f)     Certain Cash Payments. If an Optionee would not be permitted to
exercise an Option or any portion thereof (for purposes of this subsection (f)
only, each such Option being referred to as a "Subject Option") or dispose of
the Shares received upon the exercise thereof without loss or liability (other
than a loss or liability for the exercise price, applicable withholding or any
associated transactional cost), or if the Board determines that the Optionee may
not be permitted to exercise the same rights or receive the same consideration
with respect to the Sale of the Company as a shareholder of the Company with
respect to any Subject Options or portion thereof or the Shares received upon
the exercise thereof, then notwithstanding any other provision of this Plan and
unless the Committee shall provide otherwise in an agreement with such Optionee
with respect to any Subject Options, such Optionee shall have the right, whether
or not the Subject Option is fully exercisable or may be otherwise realized by
the Optionee, by giving notice during the 60-day period from and after a Sale to
the Company, to elect to surrender all or part of any Subject Options to the
Company and to receive cash, within 30 days of such notice, in an amount equal
to the amount by which the "Sale Price" (as defined herein) per share of Common
Stock on the date of such election shall exceed the amount which the Optionee
must pay to exercise the Subject Options per share of Common Stock under such
Subject Options (the "Spread") multiplied by the number of shares of Common
Stock granted under the Subject Options as to which the right granted hereunder
shall be applicable and shall have been exercised; provided, however, that if
the end of such 60- day period from and after a Sale is within six months of the
date of grant of a Subject Option held by an Optionee (except an Optionee who
has deceased during such six month period) who is an officer or director of the
Company (within the meaning of Section 16(b) of the Exchange Act), such Subject
Option shall be canceled in exchange for a payment to the Optionee, effective on
the day which is six months and one day after the date of grant of such Subject
Option, equal to the Spread multiplied by the number of shares of Common Stock
granted under the Subject Option. With respect to any Optionee who is an officer
or director of the Company (within the meaning of Section 16(b) of the Exchange
Act), the 60-day period shall be extended, if necessary, to include the "window
period" of Rule 16(b)-3 which first commences on or after the date of the Sale,
and the Committee shall have sole discretion, if necessary, to approve the
Optionee's exercise


                                           10


<PAGE>   11



hereunder and the date on which the Spread is calculated may be adjusted, if
necessary, to a later date if necessary to avoid liability to such Optionee
under Section 16(b). For purposes of the Plan, "Sale Price" means the higher of
(a) the highest reported sales price of a share of Common Stock in any
transaction reported on the principal exchange on which such shares are listed
or on NASDAQ during the 60-day period prior to and including the date of a Sale
or (b) if the Sale is the result of a tender or exchange offer or a corporate
transaction, the highest price per share of Common Stock paid in such tender or
exchange offer or a corporate transaction, except that, in the case of Incentive
Stock Options, such price shall be based only on the Fair Market Value of the
Common Stock on the date such Incentive Stock Option is exercised. To the extent
that the consideration paid in any such transaction described above consists all
or in part of securities or other non-cash consideration, the value of such
securities or other non-cash consideration shall be determined in the sole
discretion of the Committee.

        (g)     Mitigation of Excise Tax. If any payment or right accruing to an
Optionee under this Plan (without the application of this Section), either alone
or together with other payments or rights accruing to the Optionee from the
Company or an affiliate ("Total Payments") would constitute a "parachute
payment" (as defined in Section 280G of the Code and regulations thereunder),
the Committee may in each particular instance determine to (a) reduce such
payment or right to the largest amount or greatest right that will result in no
portion of the amount payable or right accruing under the Plan being subject to
an excise tax under Section 4999 of the Code or being disallowed as a deduction
under Section 280G of the Code, or (b) take such other actions, or make such
other arrangements or payments with respect to any such payment or right as the
Committee may determine in the circumstances. Any such determination shall be
made by the Committee in the exercise of its sole discretion, and such
determination shall be conclusive and binding on the Optionee. The Optionee
shall cooperate as may be requested by the Committee in connection with the
Committee's determination, including providing the Committee with such
information concerning such Optionee as the Committee may deem relevant to its
determination.

        11.     Time of Granting Options. The date of grant of an Option shall, 
for all purposes, be the date on which the Committee makes the determination
granting such Option. Notice of the determination shall be given to each
Employee, Consultant or Outside Director to whom an Option is so granted within
a reasonable time after the date of such grant. If the Committee cancels, with
the consent of Optionee, any Option granted under this Plan, and a new Option is
substituted therefor, the date that the canceled Option was originally granted
shall be the date used to determine the earliest date for exercising the new
substituted Option under Section 7 of this Plan so that the Optionee may
exercise the substituted Option at the same time as if the Optionee had held the
substituted Option since the date the canceled Option was granted.

        12.     Amendment and Termination of Plan.

        (a)     Amendment and Termination. The Board or the Committee may amend,
waive or terminate this Plan from time to time in such respects as it shall deem
advisable; provided that, to the extent necessary to comply with Rule 16b-3 or
with Section 422 of the Code (or any other successor or applicable law or
regulation), the Company shall obtain shareholder approval of any Plan amendment
in such a manner and to such a degree as is required by the applicable law, rule
or regulation.

        (b)     Effect of Amendment or Termination. Any such amendment or
termination of this Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Committee, which agreement must be in writing and signed by the Optionee and
the Company.

        13.     Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, and the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

        As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned relevant provisions of law.

        14.     Restrictions on Shares. Shares of Common Stock issued upon 
exercise of an Option shall be subject to the terms and conditions specified
herein and to such other terms, conditions and restrictions as the Committee in
its discretion may determine or provide in the grant. The Company shall not be
required to issue or deliver any certificates for shares of Common Stock, cash
or other property prior to (i) the listing of such shares on any stock exchange
(or other public market) on which the Common Stock may then be listed (or
regularly traded), (ii) the completion of any registration or qualification of
such shares under federal or state law, or any ruling or regulation of any
government body which the Committee determines to be necessary or advisable, and
(iii) the satisfaction of any applicable withholding obligation in order for the
Company or an affiliate to obtain a deduction with respect to the exercise of an
Option. The Company may cause any certificate for any share of Common Stock to
be delivered to be properly marked with a legend or other notation reflecting
the limitations on transfer of such Common Stock as provided in this Plan or as
the Committee may otherwise require. The Committee may require any person
exercising an Option to make such representations and furnish such information
as it may consider appropriate in connection with the issuance or delivery of
the shares of Common Stock in compliance with applicable law or otherwise.


                                           12


<PAGE>   13



Fractional shares shall not be delivered, but shall be rounded to the next lower
whole number of shares.

        15.     Shareholder Rights. No person shall have any rights of a 
shareholder as to shares of Common Stock subject to an Option until, after
proper exercise of the Option or other action required, such shares shall have
been recorded on the Company's official shareholder records as having been
issued or transferred. Subject to the preceding Section and upon exercise of the
Option or any portion thereof, the Company will have thirty (30) days in which
to issue the shares, and the Optionee will not be treated as a shareholder for
any purpose whatsoever prior to such issuance. No adjustment shall be made for
cash dividends or other rights for which the record date is prior to the date
such shares are recorded as issued or transferred in the Company's official
shareholder records, except as provided herein or in an agreement.

        16.     Registration. If there has been a public offering of the 
Company's Common Stock, the Company may register under the Securities Act the
Common Stock delivered or deliverable pursuant to Options on Commission Form S-8
if available to the Company for this purpose (or any successor or alternate form
that is substantially similar to that form to the extent available to effect
such registration), in accordance with the rules and regulations governing such
forms, as soon as such forms are available for registration to the Company for
this purpose. The Company will, if it so determines, use its good faith efforts
to cause the registration statement to become effective as soon as possible and
will file such supplements and amendments to the registration statement as may
be necessary to keep the registration statement in effect until the earliest of
(a) one year following the expiration of the option period of the last Option
outstanding, (b) the date the Company is no longer a reporting company under the
Exchange Act and (c) the date all Optionees have disposed of all shares
delivered pursuant to any Option. The Company may delay the foregoing actions at
any time and from time to time if the Committee determines in its discretion
that any such registration would materially and adversely affect the Company's
interests or if there is no material benefit to Optionees.

        17.     Reservation of Shares. The Company, during the term of this 
Plan, will at all times reserve and keep available such number of Shares as
shall be sufficient to permit the exercise of all Options outstanding under this
Plan. The inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained for any
reason.

        18.     Option Agreements. Options shall be evidenced by written Option
agreements in such form as the Committee shall approve.

        19.     Information to Optionees. To the extent required by applicable 
law, the Company shall provide to each Optionee, during the period for which
such Optionee has one or more Options outstanding, copies of all annual reports
and other information which are provided to all stockholders of the Company.
Except as otherwise noted in the


                                           13


<PAGE>   14



foregoing sentence, the Company shall have no obligation or duty to
affirmatively disclose to any Optionee, and no Optionee shall have any right to
be advised of, any material information regarding the Company or any Parent or
Subsidiary at any time prior to, upon or otherwise in connection with, the
exercise of an Option.

        20.     Funding. Benefits payable under this Plan to any person shall be
paid directly by the Company. The Company shall not be required to fund or
otherwise segregate assets to be used for payment of benefits under this Plan.

        21.     Controlling Law. This Plan shall be governed by the laws of the
state of incorporation of the Company at the time of determination of any issues
raised with respect to the interpretation or enforcement of this Plan, without
application of any conflict of laws principles.

     RESOLVED, that the Nanophase Technologies Corporation Amended and Restated
1992 Stock Option Plan (the "Plan") be and hereby is amended, subject to
shareholder approval, as follows:

                                       I

              otherwise amended by the Board and approved by the 
              stockholders of the Company as required by law, the 
              maximum  aggregate number of Shares issuable under this 
              Plan is 4,763,440, 4,613,440 of which shall be reserved 
              for issuance  to Employees and Consultants and 150,000 
              of which shall be reserved for issuance to Outside 
              Directors, and such Shares are hereby made available 
              and shall be reserved for issuance under this Plan."

                                       II

        In all other respects, the Plan shall continue in full force
        and effect.

                                                                EXHIBIT 10.2


                                   FORM OF
                          INDEMNIFICATION AGREEMENT


     THIS INDEMNIFICATION AGREEMENT (the "AGREEMENT") is entered into as of
this ___ day of _______________, 1997, by and between NANOPHASE TECHNOLOGIES
CORPORATION, an Illinois corporation (the "CORPORATION"), and _____________
("INDEMNITEE").

                                    RECITALS

     A. The Corporation is aware that because of the increased exposure to
litigation costs and risks resulting from service to corporations, talented and
experienced persons are increasingly reluctant to serve or continue serving as
directors or executive officers of corporations unless they are protected by
comprehensive liability insurance and indemnification;

     B. Plaintiffs often seek damages in such large amounts, and the costs of
litigation may be so great (whether or not the case is meritorious), that the
defense and/or settlement of such litigation is usually beyond the personal
resources of directors and executive officers;

     C. Based upon their experience as business managers, the Board of
Directors of the Corporation (the "BOARD") has concluded that, to retain and
attract talented and experienced individuals to serve as directors and
executive officers of the Corporation, it is appropriate for the Corporation to
contractually indemnify its directors and certain of its executive officers,
and to assume for itself liability for expenses and damages in connection with
claims against such directors and executive officers in connection with their
service to the Corporation; and

     D. The Corporation believes that it is fair and proper to protect its
directors and certain executive officers of the Corporation from the risk of
judgments, settlements and other expenses which may occur as a result of their
service to the Corporation.

     NOW, THEREFORE, the parties, intending to be legally bound, for good and
valuable consideration, hereby agree as follows:

     1.    DEFINITIONS.

           (a) AGENT.  "AGENT" means a director or executive officer of the
      Corporation or a director or executive officer of another foreign or
      domestic corporation, partnership, joint venture, trust or other
      enterprise serving at the request, for the convenience, or to represent
      the interests of the Corporation.

           (b) CORPORATION.  "CORPORATION" means Nanophase Technologies
      Corporation, an Illinois corporation, its successors or assigns, or any
      Subsidiary of the Corporation.  "SUBSIDIARY" means, and "SUBSIDIARIES"
      include, (i) any company of which more than fifty percent (50%) of the
      outstanding voting securities are owned

<PAGE>   2

      directly or indirectly by the Corporation, or which is otherwise
      controlled by the Corporation, and (ii) any partnership, joint venture,
      trust, or other entity of which more than fifty percent (50%) of the
      equity interest is owned directly or indirectly by the Corporation, or
      which is otherwise controlled by the Corporation.

           (c) LIABILITIES.  "LIABILITIES" means losses, claims, damages,
      liabilities, obligations, penalties, judgments, fines, settlement
      payments, awards, costs, expenses and disbursements (and any and all
      costs, expenses or disbursements in giving testimony or furnishing
      documents in response to a subpoena or otherwise), including, without
      limitation, all reasonable attorneys' fees, costs, expenses and
      disbursements, as and when incurred.

           (d) PROCEEDING.  "PROCEEDING" means any threatened, pending, or
      completed action, suit or other proceeding whether civil, criminal,
      administrative, investigative or any other type whatsoever.

           (e) CONTROL. "CONTROL" means, with respect to any person or entity,
      the possession, direct or indirect, of the power to direct or cause the
      direction of the management and policies of such person or entity,
      whether through the ownership of voting securities, by contract or
      otherwise.

      2. MAINTENANCE OF LIABILITY INSURANCE.

           The Corporation hereby covenants and agrees to and with Indemnitee
      that, so long as Indemnitee shall continue to serve as an Agent and
      thereafter so long as Indemnitee shall be subject to any claim or
      Proceeding by reason of the fact that Indemnitee was an Agent or in
      connection with Indemnitee's acts as such an Agent, the Corporation shall
      obtain and maintain in full force and effect directors' and officers'
      liability insurance ("D&O INSURANCE") in reasonable amounts from
      established and reputable insurers.  In all policies of D&O Insurance,
      Indemnitee shall be named as an insured.

      3. INDEMNIFICATION OF AGENT.

           (a) THIRD PARTY ACTIONS.  If Indemnitee is a person who was or is a
      party or is threatened to be made a party to any Proceeding (other than
      an action by or in the right of the Corporation) by reason of the fact
      that Indemnitee is or was an Agent of the Corporation, or by reason of
      anything done or not done by Indemnitee in any such capacity or otherwise
      at the request of the Corporation or of its officers, directors or
      shareholder, the Corporation shall indemnify, defend and hold harmless
      Indemnitee against any and all Liabilities actually and reasonably
      incurred by Indemnitee in connection with the investigation, defense,
      settlement or appeal of such Proceeding, so long as Indemnitee acted in
      good faith and in a manner Indemnitee reasonably believed to be in, or
      not opposed to, the best interests of the Corporation, and, with respect
      to any criminal action or Proceeding, if Indemnitee had no reasonable
      cause to believe his conduct was unlawful.



                                     -2-
<PAGE>   3


           (b) DERIVATIVE ACTIONS.  If Indemnitee is a person who was, or is a
      party or is threatened to be made a party, to any Proceeding by or in the
      right of the Corporation to procure a judgment in its favor by reason of
      the fact that Indemnitee is or was an Agent of the Corporation, or by
      reason of anything done or not done by Indemnitee in any such capacity or
      otherwise at the request of the Corporation or of its officers, directors
      or shareholders, the Corporation shall indemnify, defend and hold
      harmless Indemnitee against all Liabilities actually and reasonably
      incurred by Indemnitee in connection with the investigation, defense,
      settlement or appeal of such Proceeding, if Indemnitee acted in good
      faith and in a manner he reasonably believed to be in or not opposed to
      the best interests of the Corporation; provided, however, that no
      indemnification under this SECTION 3(B) shall be made in respect of any
      claim, issue or matter for which such person is adjudged to be liable for
      gross negligence or willful misconduct in the performance of Indemnitee's
      duties to the Corporation, unless, and only to the extent that, the court
      in which such Proceeding was brought shall determine upon application
      that, despite the adjudication of liability, but in view of all the
      circumstances of the case, Indemnitee is fairly and reasonably entitled
      to indemnity for such Liabilities as the court shall deem proper.

           (c) ACTIONS WHERE INDEMNITEE IS DECEASED.  If Indemnitee is a person
      who was or is a party or is threatened to be made a party to any
      Proceeding by reason of the fact that he is or was an Agent of the
      Corporation, or by reason of anything done or not done by Indemnitee in
      any such capacity, and prior to, during the pendency of, or after
      completion of, such Proceeding, Indemnitee shall die, then the
      Corporation shall indemnify, defend and hold harmless the estate, heirs
      and legatees of Indemnitee against any and all Liabilities incurred by
      such estate, heirs or legatees in connection with the investigation,
      defense, settlement or appeal of such Proceeding on the same basis as
      provided for Indemnitee in SECTIONS 3(a) AND 3(b) above.

           (d)  REDUCTION OF LIABILITIES.  The Liabilities covered hereby shall
      be net of any payments to or on behalf of Indemnitee by D&O Insurance
      carriers or others with respect to the subject Proceeding.
 
      4. INDEMNIFICATION AS WITNESS.  Notwithstanding any other provision of
      this Agreement, to the extent Indemnitee is, by reason of the fact that
      Indemnitee is or was an Agent of the Corporation, involved in any
      investigative Proceeding, including but not limited to testifying as a
      witness or furnishing documents in response to a subpoena or otherwise,
      Indemnitee shall be indemnified against any and all Liabilities actually
      and reasonably incurred by or for Indemnitee in connection therewith.

      5. ADVANCEMENT OF LIABILITIES.  Subject to the provisions of SECTION
      6(c), until a determination that Indemnitee is not entitled to be
      indemnified by the Corporation under the terms hereof, and unless the
      provisions of SECTION 9 apply, the Corporation shall reimburse Indemnitee
      for Liabilities previously paid by Indemnitee and may advance Liabilities
      which the Corporation reasonably determines will be due and payable by
      Indemnitee within a reasonable time after a request for advancement is
      made by Indemnitee.  The execution and delivery of this Agreement by the
      Corporation evidences the specific approval by the Board of the
      reimbursement and advancement of Liabilities


                                     -3-
<PAGE>   4


      as provided for in this SECTION 5.  As a condition to such reimbursement
      and/or advancement, Indemnitee shall, at the request of the Corporation,
      undertake in a manner satisfactory to the Corporation to repay such
      amounts reimbursed and/or advanced, without interest, if it shall
      ultimately be determined pursuant to SECTION 7 OR 9 below that Indemnitee
      is not entitled to be indemnified by the Corporation under the terms of
      this Agreement.  Subject to the foregoing, the reimbursement and/or
      advances to be made hereunder shall be paid by the Corporation to
      Indemnitee within twenty (20) business days following delivery of a
      written request by Indemnitee to the Corporation, which request shall be
      accompanied by vouchers, invoices and similar evidence documenting the
      amounts incurred or to be incurred by Indemnitee.

      6.   INDEMNIFICATION PROCEDURES.

           (a) NOTICE BY INDEMNITEE.  Promptly after receipt by Indemnitee of
      notice of the commencement or threat of commencement of any Proceeding,
      Indemnitee shall, if Indemnitee believes that indemnification with
      respect thereto may be sought from the Corporation under this Agreement,
      notify the Corporation of the commencement or threat of commencement
      thereof, provided that any failure to so notify the Corporation shall not
      relieve the Corporation of its obligations hereunder, except to the
      extent that such failure or delay increases the liability of the
      Corporation hereunder.

           (b) D & O INSURANCE.  If, at the time of receipt of a notice
      pursuant to SECTION 6(a) above, the Corporation has D&O Insurance in
      effect, the Corporation shall give prompt notice of the Proceeding or
      claim to its insurers in accordance with the procedures set forth in the
      applicable policies.  The Corporation shall thereafter take all necessary
      or desirable action to cause such insurers to pay all amounts payable as
      a result of such Proceeding in accordance with the terms of such
      policies, and Indemnitee shall not take any action (by waiver, settlement
      or otherwise) which would adversely affect the ability of the Corporation
      to obtain payment from its insurers.

           (c) ASSUMPTION OF DEFENSE.  In the event the Corporation shall be
      obligated under this Agreement to pay the Liabilities of Indemnitee, the
      Corporation shall be entitled to assume the defense (with counsel
      reasonably acceptable to Indemnitee, approval thereof not to be
      unreasonably withheld) of the Proceeding to which the Liabilities relate.
      The Corporation agrees to promptly notify Indemnitee upon its election
      to assume such defense.  Once the Corporation (i) provides Indemnitee
      with notice of its election to assume such defense and (ii) obtains
      approval from Indemnitee of the counsel retained, the Corporation will
      not be liable to Indemnitee under this Agreement for any attorney's fees
      or other Liabilities subsequently incurred by the Indemnitee with respect
      to such Proceeding, unless (x) the Liabilities incurred by the Indemnitee
      were previously authorized by the Corporation or (y) counsel for the
      Indemnitee shall have provided the Corporation with an opinion of counsel
      stating that there is a likelihood that a conflict of interest exists
      between the Corporation and the Indemnitee in the conduct of any such
      defense.

      7.   DETERMINATION OF RIGHT TO INDEMNIFICATION.

           (a) SUCCESSFUL PROCEEDING.  To the extent Indemnitee has been
      successful, on the merits or otherwise, in the defense of any Proceeding
      referred to in SECTIONS 3(a) OR 3(b) above, the Corporation shall
      indemnify Indemnitee against all Liabilities incurred by him in
      connection therewith.  If Indemnitee is not wholly successful in such
      Proceeding, but is successful, on the merits or otherwise, as to one or
      more but less than all claims, issues or matters in such Proceeding, then
      the Corporation shall indemnify Indemnitee against all Liabilities
      actually or reasonably incurred by or for him in connection with each
      successfully resolved claim, issue or matter.  For purposes of this
      SECTION 7(a), and without limitation, the termination of any Proceeding,
      or any claim, issue, or matter in such a Proceeding, by dismissal, with
      or without prejudice, shall be deemed to be a successful result as to
      such Proceeding, claim, issue or matter, so long as there has been no
      finding (either adjudicated or pursuant to SECTION 7(c) below) that
      Indemnitee (i) did not act in good faith, (ii) did not act in a manner
      reasonably believed to be in, or not opposed to, the best interests of
      the Corporation, or (iii) with respect to any criminal proceeding, had
      reasonable grounds to believe his conduct was unlawful.

           (b) OTHER PROCEEDINGS.  In the event that SECTION 7(a) above is
      inapplicable, the Corporation shall nevertheless indemnify Indemnitee,
      unless and only to the extent that the forum listed in SECTION 7(c) below
      determines that Indemnitee has not met the applicable standard of conduct
      set forth in SECTIONS 3(a) OR 3(b) above required to entitle Indemnitee
      to such indemnification.

           (c) FORUM IN EVENT OF DISPUTE.  The determination that
      indemnification of Indemnitee is proper in the circumstances because
      Indemnitee has met the applicable standard of conduct set forth in
      SECTIONS 3(a) OR 3(b) shall be made (i) by the Board, by a majority vote
      of the directors who are not parties to such Proceeding, even though less
      than a quorum, or (ii) by a committee of disinterested directors
      designated by a majority of such disinterested directors, even though
      less than a quorum, or (iii) if there are no such disinterested
      directors, or if such disinterested directors shall so direct, by
      independent legal counsel in a written opinion, or (iv) by the
      shareholders of the Corporation.  The choice of which forum shall make
      the determination shall be made by the Board.  The forum shall act in the
      utmost good faith to assure Indemnitee a complete opportunity to present
      to the forum Indemnitee's case that Indemnitee has met the applicable
      standard of conduct.

           (d) APPEAL TO COURT.  Notwithstanding a determination by any forum
      listed in SECTION 7(c) above that Indemnitee is not entitled to
      indemnification with respect to a specific Proceeding, Indemnitee shall
      have the right to apply to the court in which that Proceeding is or was
      pending or any other court of competent jurisdiction for the purpose of
      enforcing Indemnitee's right to indemnification pursuant to this
      Agreement.

           (e) INDEMNITY FOR LIABILITIES IN ENFORCEMENT OF AGREEMENT.
      Notwithstanding any other provision in this Agreement to the contrary,
      the Corporation shall indemnify Indemnitee against all Liabilities
      incurred by Indemnitee in connection with any other Proceeding between
      the Corporation and Indemnitee involving the

                                     -5-

<PAGE>   6

      interpretation or enforcement of the rights of Indemnitee under this
      Agreements unless a court of competent jurisdiction finds that the
      material claims and/or defenses of Indemnitee in any such Proceeding were
      frivolous or made in bad faith.

      8.   CONTRIBUTION.  If and to the extent that a final adjudication shall
      specify that the Corporation is not obligated to indemnify Indemnitee
      under this Agreement for any reason (including but not limited to the
      exclusion set forth in SECTION 9 hereof), then in respect of any
      Proceeding in which the Corporation is jointly liable with Indemnitee (or
      would be so liable if joined in such action, suit or proceeding), the
      Corporation shall contribute to the amount of Liabilities reasonably
      incurred and paid or payable by Indemnitee in connection with such
      Proceeding in such proportion as is appropriate to reflect (i) the
      relative benefits received by the Corporation, on the one hand, and
      Indemnitee, on the other hand, from the transaction with respect to which
      such Proceeding arose, and (ii) the relative fault of the Corporation, on
      the one hand, and  Indemnitee, on the other hand, in connection with the
      circumstances which resulted in such Liabilities, as well as any other
      relevant equitable considerations.  The relative fault of the
      Corporation, on the one hand, and Indemnitee, on the other hand, shall be
      determined by reference to, among other things, the parties' relative
      intent, knowledge, access to information and opportunity to correct or
      prevent the circumstances resulting in such Liabilities.  The Corporation
      agrees that it would not be just and equitable if contribution pursuant
      to this SECTION 8 were determined by pro rata allocation or any other
      method of allocation which does not take account of the foregoing
      equitable considerations.

      9.   EXCEPTIONS.

           (a) CLAIMS INITIATED BY INDEMNITEE.  Notwithstanding any other
      provision herein to the contrary, the Corporation shall not be obligated
      pursuant to the terms of this Agreement to indemnify or advance
      Liabilities to Indemnitee with respect to Proceedings or claims initiated
      or brought voluntarily by Indemnitee and not by way of defense, except
      with respect to Proceedings brought to establish or enforce a right to
      indemnification under this Agreement, but such indemnification or
      advancement of expenses may be provided by the Corporation in specific
      cases if the Board finds it to be appropriate.

           (b) UNAUTHORIZED SETTLEMENTS.  Notwithstanding any other provision
      herein to the contrary, the Corporation shall not be obligated pursuant
      to the terms of this Agreement to indemnify Indemnitee under this
      Agreement for any amount paid in settlement of a Proceeding without the
      prior written consent of the Corporation to such settlement.

           (c) NO DUPLICATIVE PAYMENT.  The Corporation shall not be liable
      under this Agreement to make any payment of amounts otherwise
      indemnifiable hereunder if and to the extent that Indemnitee has
      otherwise actually received such payment under any insurance policy,
      contract, agreement or otherwise.


                                     -6-

      10. CERTIFICATE OF INCORPORATION AND BY-LAWS.  The Corporation agrees
      that the Certificate of Incorporation and By-laws of the Corporation in
      effect on the date hereof shall not be amended to reduce, limit, hinder
      or delay (a) the rights of Indemnitee granted hereby, or (b) the ability
      of the Corporation to indemnify Indemnitee as required hereby.  The
      Corporation further agrees that it shall exercise the powers granted to
      it under its Certificate of Incorporation, its By-laws and by applicable
      law to indemnify any Indemnitee to the fullest extent possible as
      required hereby.

      11. NON-EXCLUSIVITY.  The provisions for indemnification and advancement
      of Liabilities set forth in this Agreement shall not be deemed exclusive
      of any other rights which the Indemnitee may have under any provision of
      law, the Corporation's Certificate of Incorporation or By-laws, the vote
      of the Corporation's shareholder or disinterested directors, other
      agreements or otherwise.

      12. INTERPRETATION OF AGREEMENT.  It is understood that the parties
      hereto intend this Agreement to be interpreted and enforced so as to
      provide indemnification to Indemnitee to the fullest extent now or
      hereafter permitted by law.

      13. SEVERABILITY.  If any provision or provisions of this Agreement shall
      be held to be invalid, illegal or unenforceable for any reason
      whatsoever, (i) the validity, legality and enforceability of the
      remaining provisions of the Agreement (including, without limitation, all
      portions of any paragraphs of this Agreement containing any such
      provision held to be invalid, illegal or unenforceable) shall not in any
      way be effected or impaired thereby, and (ii) to the fullest extent
      possible, the  provisions of this Agreement (including, without
      limitation, all portions of any paragraph of this Agreement containing
      any such provision held to be invalid, illegal, or unenforceable, that
      are not themselves invalid, illegal, or unenforceable) shall be construed
      so as to give effect to the intent manifested by the provision held
      invalid, illegal or unenforceable and to give effect to SECTION 12
      hereof.

      14. MODIFICATION AND WAIVER.  No supplement, modification or amendment to
      this Agreement shall be binding unless executed in writing by both of the
      parties hereto.  No waiver of any of the provisions of this Agreement
      shall be deemed, or shall constitute, a waiver of any other provisions
      hereof (whether or not similar), nor shall such waiver constitute a
      continuing waiver.

      15. SUBROGATION.  In the event that the Corporation makes any payment
      under this Agreement, the Corporation shall be subrogated to the extent
      of such payment to all of the rights of recovery of Indemnitee, who shall
      execute all papers and do all things that may be necessary to secure such
      rights, including but not limited to the execution of such documents as
      shall be necessary to enable the Company effectively to bring suit to
      enforce such rights.

      16. SURVIVAL, SUCCESSORS, AND ASSIGNS.  Indemnitee's rights under this
      Agreement shall continue after Indemnitee has ceased acting as an Agent
      of the Corporation.  The terms of this Agreement shall be binding on and
      inure to the benefit of the Corporation

                                     -7-

<PAGE>   8


      and its successors and assigns and shall be binding on and inure to the
      benefit of Indemnitee and Indemnitee's heirs, executors and
      administrators.

      17. NOTICES.  All notices, demands, consents, requests, approvals and
      other communications between the parties pursuant to this Agreement must
      be in writing and will be deemed given when delivered in person, one (1)

               AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT


                 Amended and Restated Registration Rights Agreement
("Agreement") dated March 16, 1994, among Nanophase Technologies Corporation,
an Illinois corporation (with its successors and assigns, called the
"Company"), and the persons listed as Holders on the signature pages of a
counterpart of this Agreement.

                 Capitalized terms used in this Agreement and not otherwise
defined are defined in Section 11 of this Agreement.


                             PRELIMINARY STATEMENT

                 The Company and the Holders have previously entered into that
certain Registration Rights Agreement dated as of November 21, 1991, as amended
by a First Amendment to Registration Rights Agreement dated February 8, 1993
(collectively, the "Original Agreement").

                 Concurrently with the execution of this Agreement, the Company
and certain of the Holders propose to execute a Series D Preferred Stock
Purchase Agreement (the "Series D Purchase Agreement") pursuant to which
certain of the Holders will purchase additional securities of the Company.  To
induce such Holders to execute the Series D Purchase Agreement, the Company and
the Holders agree to amend and restate the Original Agreement as follows.

                                   AGREEMENT

                 Section 1.       Required Registrations.

                 1.1      (a)  The Holders of Preferred and Registrable Common
equivalent to more than 60% of the Registrable Common may, by a written notice
to the Company, request that the Company register any Registrable Common
specified in the notice, under the Securities Act on a form other than a Short
Form and under other relevant securities laws, for disposition in accordance
with methods stated in the notice.  Such notice may specify an underwriter for
such registration.

                 1.2      When it receives a registration notice under Section
1.1, the Company shall, within three (3) days, deliver a copy of such
registration notice to each Holder of Convertible Securities or Registrable
Common who is not a party to the registration notice, each of whom may then
specify, by written notice to the Company delivered within fifteen (15) days of
receipt of the notice from the Company, a number of shares of Registrable
Common held by it which it wishes to include in any registration pursuant to
the registration notice under Section 1.1.
<PAGE>   2
                 1.3  When it receives a registration notice under Section 1.1,
the Company will expeditiously cause a registration statement to be filed, and
use its best efforts to cause such registration statement to become effective
under the Securities Act for the Registrable Common specified in the
registration notice under Section 1.1 and subsequent notices under Section 1.2
to permit disposition by such Holders in accordance with the methods of
disposition described in the registration notice.

                 Section 2.       Registrations on Short Forms.

                 2.1  If at any time the Company is a registrant entitled to
use a Short Form to register Registrable Common, one or more Holders may, by a
written notice to the Company, request that the Company register Registrable
Common specified in the notice on a Short Form.

                 2.2  When it receives a Short Form registration notice under
Section 2.1, the Company shall, within three (3) days, deliver a copy of such
registration notice to each Holder of Convertible Securities or Registrable
Common, who is not a party to such registration notice, each of whom may then
specify, by written notice to the Company delivered within fifteen (15) days of
receipt of the notice from the Company, a number of shares of Registrable
Common held by it that it wishes to include in any registration pursuant to the
registration notice under Section 2.1 hereof.

                 2.3  When it receives a notice under Section 2.1, and
provided that the reasonably anticipated price to the public of the Registrable
Common proposed to be registered by all sellers of such Registrable Common
would total more than $500,000, the Company will expeditiously cause a
registration statement to be filed, and use its best efforts to cause such
registration statement to become effective under the Securities Act on the
Short Form specified in the notice for the Registrable Common specified in the
registration notice under Section 2.1 and subsequent notices under Section 2.2.

                 Section 3.  Incidental Registration.  Each time the
Company proposes to register any of its Securities under the Securities Act, it
will give written notice of its intention to do so to each Holder, which notice
shall identify the proposed underwriter for such offering.  Each Holder may
then specify, by written notice to the Company delivered within fifteen (15)
days of receipt of notice from the Company, a number of shares of Registrable
Common held by it which it wishes to include in the Company's proposed
registration.  If at least 50% of the shares to be registered in such offering
are held by Holders of Preferred or Registrable Common, then such Holders shall
have the right to approve the underwriter (voting as a group, based upon the
number of shares of Registrable Common held by each to be included in such
offering), which approval shall not be unreasonably withheld.  Subject to the
limitations of Section 8, the Company will use its best efforts to effect the
registration under the Securities Act of Registrable Common specified by
Holders under this Section 3.





                                                                          Page 2

<PAGE>   3
                 Section 4.       Limitations on Registration Rights.
Notwithstanding any contrary provision of this Agreement:

                 A.       the Company shall not be required to effect more than
         one registration pursuant to Section 1 (for purposes of this Section
         4.A., a registration shall not be deemed "effective" unless the
         registration statement is declared effective by the Commission); and

                 B.       Section 3 shall not apply to a registration effected
         solely to implement an employee benefit plan or to any other form or
         type of registration which does not permit inclusion of Registrable
         Common pursuant to Commission rule or practice; and

                 C.       if the registration notice under Section 1 would
         result in the first offering of the Company's Securities to the
         public, then the registration specified under Section 1.1 must be for
         an underwritten public offering to be managed by an underwriter of
         recognized national standing reasonably acceptable to the Company and
         shall be for a minimum of $10,000,000, at a price of not less than
         $3.00 per share, as adjusted for stock splits, stock dividends and
         other similar events; and

                 D.       the Company shall not be obligated to effect a
         registration pursuant to Section 1 during the period starting with the
         date thirty days prior to the Company's estimated date of filing of,
         and ending on a date six months following the effective date of, a
         registration pertaining to an underwritten public offering of
         securities for the account of the Company, provided that the Company
         is actively employing in good faith all reasonable efforts to cause
         such registration statement to become effective and that the Company's
         estimates of the date of filing of such registration statement is made
         in good faith; and

                 E.       if (a) there is material non-public information
         regarding the Company which the Board reasonably determines not to be
         in the Company's best interest to disclose and which the Company is
         not otherwise required to disclose, or (b) there is a significant
         business opportunity available to the Company which the Board
         reasonably determines not to be in the Company's best interest to
         disclose, or (c) there is a significant business opportunity available
         to the Company and the Board reasonably determines that the Company's
         ability to pursue such opportunity would be materially and adversely
         affected by a registered public offering of the Company's Securities,
         then the Company may postpone filing a registration statement
         requested pursuant to Sections 1 or 2 for a period not to exceed 90
         days, provided that the Company may not postpone its obligations as
         permitted under this Section 4.E. more than once every 12 months.





                                                                          Page 3
<PAGE>   4
                 Section 5.       Registration Procedures.

                 5.1      Whenever the Company is required by the provisions of
this Agreement to effect the registration of any Registrable Common under the
Securities Act, the Company will, as expeditiously as possible:

                 A.       in the case of a registration required under Section
         1, engage the underwriters designated by the Holders giving notice
         under Section 1.1 or in the case of an incidental registration under
         Section 3, the underwriter specified in the notice given to the
         Holders and approved by the Holders;

                 B.       before filing each registration statement or
         prospectus or amendment or supplement thereto with the Commission,
         furnish counsel for the Holders of Registrable Common included in such
         registration with copies of all such documents proposed to be filed
         which shall be subject to the reasonable approval of such counsel;

                 C.       prepare and file with the Commission a registration
         statement with respect to such Registrable Common and use its best
         efforts to cause such registration statement to become and remain
         effective for such period as may be reasonably necessary to effect the
         sale of such securities, not to exceed nine months;

                 D.       prepare and file with the Commission (and any
         exchange on which the Company's Securities may be or are proposed to
         be listed and with the National Association of Securities Dealers,
         Inc.) such amendments and supplements to such registration statement
         and the prospectus used in connection therewith as may be necessary to
         keep such registration statement effective for such period and to
         comply with the provisions of the Securities Act with respect to the
         sale or other disposition of all Registrable Common covered by such
         registration statement in accordance with the intended methods of
         disposition set forth in such registration statement, but only to the
         extent provided in this Section 5;

                 E.       prepare and promptly file with the Commission, and
         notify each seller of such Registrable Common as expeditiously as
         possible of the necessity for and the filing of, such amendment or
         supplement to such registration statement or prospectus as may be
         necessary to correct any statements or omissions if, during such
         periods as a prospectus relating to such securities is required to be
         delivered under the Securities Act, any event shall have occurred as
         the result of which any such prospectus or any other prospectus as
         then in effect would include an untrue statement of a material fact or
         omit to state any material fact necessary to make the statements
         therein, in the light of the circumstances in which they were made,
         not misleading;

                 F.       furnish to the underwriters and each seller of such
         Registrable Common such numbers of copies of such registration
         statement, each amendment and supplement thereto, the prospectus
         included in such registration statement (including





                                                                          Page 4
<PAGE>   5
         each preliminary prospectus) and such other documents as such
         underwriters or sellers may reasonably request in order to facilitate
         the disposition of the Registrable Common subject to such registration
         statement in accordance with such registration statement;

                 G.       use its best efforts to register or qualify any
         Registrable Common covered by such registration statement under the
         securities or blue sky laws of such jurisdictions within the United
         States of America as the seller or the underwriters reasonably
         request, and to take any other acts which a seller or the underwriters
         may reasonably request under such securities or blue sky laws to
         enable the consummation of the disposition in such jurisdictions of
         such Registrable Common (provided, however, that the Company may not
         be required under this Agreement (i) to qualify generally to do
         business as a foreign corporation in any jurisdiction in which it
         would not otherwise be required to qualify, or (ii) to subject itself
         to taxation in any such jurisdiction, or (iii) to consent to general
         service of process in any such jurisdiction);

                 H.       provide a transfer agent and registrar for all
         Registrable Common sold under the registration not later than the
         effective date of the registration statement;

                 I.       cause all Registrable Common sold under the
         registration to be listed on a recognized securities exchange, if any,
         or to become eligible for trading on any over-the-counter trading
         system, on which similar securities issued by the Company are then
         listed or traded;

                 J.       enter into such customary agreements (including
         underwriting agreements in customary form) and take all such other
         actions as the underwriters, if any, or the Holders of a Majority of
         the Registrable Common being sold reasonably request in order to
         expedite or facilitate the disposition of such Registrable Common
         (including, without limitation, effecting a stock split or a
         combination of shares);

                 K.       make available for inspection by the sellers of
         Registrable Common, any underwriter participating in any disposition
         pursuant to such registration statement, and any attorney, accountant
         or other agent retained by any such seller or underwriter, all
         financial and other records, pertinent corporate documents and
         properties of the Company, and cause the Company's officers,
         directors, employees and independent accountants to supply all
         information reasonably requested by any such seller or underwriter in
         connection with such registration statement, all subject to such
         limitations as the Company reasonably deems appropriate in order to
         protect the Company's confidential or proprietary information; and





 
                                                                         Page 5
<PAGE>   6
                 L.   advise each seller of Registrable Common, immediately
         after it shall receive notice or obtain knowledge thereof, of the
         issuance of any stop order by the Commission suspending the
         effectiveness of such registration statement or the initiation or
         threatening of any proceeding for such purpose and promptly use
         reasonable efforts to prevent the issuance of any stop order or to
         obtain its withdrawal if such stop order should be issued.

                 5.2      It shall be a condition precedent to the inclusion of
the Registrable Common of any Holder in a registration effected pursuant to
this Agreement that such Holder shall furnish to the Company such information
regarding such Holder, the Registrable Common of such Holder to be registered
and the intended method of disposition of such Registrable Common, and shall
execute such indemnities with respect to such information provided by such
Holders, underwriting agreements and other documents, as the Company shall
reasonably request in order to satisfy the requirements applicable to such
registration.

                 Section 6.       Expenses.  The Company shall pay all expenses
incurred in effecting the registration of Registrable Common provided for in
this Agreement, including, without limitation, all registration and filing
fees, printing expenses, listing fees, fees and disbursements of counsel for
the Company, reasonable fees and disbursements of a single counsel for the
sellers selected by the Holders of a majority of the Registrable Common subject
to such registration, underwriting expenses other than discounts and
commissions, expenses of any audits incident to or required by any such
registration and expenses of complying with the securities or blue sky laws of
any jurisdictions pursuant to Section 5.1G hereof.  Notwithstanding the
foregoing, if a registration is requested by a single Holder pursuant to
Section 1.1(b), and no other Holder elects to have any shares owned by it
included in such registration, then the Holder requesting such registration
shall pay all of the expenses incurred in connection with such registration.

                 Section 7.       Indemnification.

                 7.1      In the event of any registration of any of its
Registrable Common under the Securities Act pursuant to this Agreement, the
Company agrees, to the extent permitted by law, to indemnify and hold harmless
each seller of such Registrable Common, each partner in, or director and
officer of, each such seller, and each other person, if any, who controls
(within the meaning of the Securities Act) such seller against any losses,
claims, damages or liabilities, joint or several, arising out of or based upon:

                 (1) any alleged untrue statement of any material fact
         contained in any registration statement under which such Securities
         were registered under the Securities Act, any preliminary prospectus
         or final prospectus contained therein, or any summary prospectus
         contained therein, or any amendment or supplement to any such
         registration statement or prospectus, or






                                                                         Page 6
<PAGE>   7
                 (2) any alleged omission to state in any such document a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, except, with respect to any seller,
         insofar as any such loss, claim, damage or liability is:

                 (a) caused by or contained in any information furnished in
         writing to the Company by such seller expressly for use in connection
         with such registration, or

                 (b) caused by such seller's failure to deliver a copy of the
         registration statement or prospectus or any amendment or supplement
         thereto as required by the Securities Act or the rules or regulations
         thereunder, or

                 (c) caused by the use of a prospectus or preliminary
         prospectus or any amendment or supplement thereto by such seller after
         receipt of notice from the Company that it should no longer be used.

In connection with an underwritten offering, the Company will indemnify such
underwriters, their officers and directors and each person who controls (within
the meaning of the Securities Act) such underwriters to the same extent as
provided above with respect to the sellers of Registrable Common and as to such
other matters as such underwriters may reasonably request or which are covered
in such underwriters' customary form of underwriters' agreement.  The Company
shall reimburse each person indemnified pursuant to this Section 7.1 in
connection with investigating or defending any loss, claim, damage, liability
or action indemnified against.  The reimbursements required by this Section 7.1
shall be made by periodic payments during the course of the investigation or
defense, as and when bills are received or expenses incurred.  The indemnities
provided pursuant to this Section 7.1 shall survive transfer of Registrable
Common by a seller.

                 7.2      In the event of any registration of any of its
Registrable Common under the Securities Act pursuant to this Agreement, each
Holder agrees to furnish to the Company in writing such information and
affidavits as the Company reasonably requests for use in connection with any
registration statement or prospectus in connection with the registration or any
amendment or supplement thereto and, to the extent permitted by law, agrees
severally and not jointly to indemnify and hold harmless the Company, its
directors and officers, each other seller of securities in such registration,
each partner in, or officer or director of, each such seller, and each person
who controls (within the meaning of the Securities Act) the Company or such
other seller against any losses, claims, damages or liabilities, joint or
several, arising out of or based upon:

                 (1) any alleged untrue statement of any material fact
         contained, on the effective date thereof, in any registration
         statement under which such Securities were registered under the
         Securities Act, any preliminary prospectus or final prospectus
         contained therein, or any summary prospectus contained therein, or any
         Securities being registered, or any amendment or supplement thereto,
         or






                                                                         Page 7
<PAGE>   8
                 (2) any alleged omission to state in any such document a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading,

but only insofar as any such loss, claim, damage or liability is caused by or
contained in any information furnished in writing to the Company by the
indemnifying seller expressly for use in connection with such registration, and
excluding any such loss, claim, damage or liability which is caused by or
contained in such statements, or caused by such omissions, based upon the
authority of an expert as defined in the Securities Act (but only if the
indemnifying seller had no ground to believe, and did not believe, that the
statements made on the authority of an expert were untrue or that there was an
omission to state a material fact.  In connection with an underwritten
offering, each seller will indemnify such underwriters, their officers and
directors and each person who controls (within the meaning of the Securities
Act) such underwriters to the same extent as provided above with respect to the
Company and other sellers.  Each seller shall reimburse each person indemnified
pursuant to this Section 7.2 in connection with investigating or defending any
loss, claim, damage, liability or action indemnified against.  The indemnities
provided pursuant to this Section 7.2 shall survive transfer of Registrable
Common by an indemnifying seller, and transfer of other securities by any other
indemnified seller.

                 7.3      Indemnification similar to that specified in Sections
7.1 and 7.2 (with such modifications as shall be appropriate) shall be given by
the Company and each Holder of any Registrable Common covered by any
registration or other qualification of Securities under any federal or state
securities law or regulation other than the Securities Act with respect to any
such registration or other qualification effected pursuant to this Agreement.

                 7.4      In the event the Company or any Holder receives a
complaint, claim or other notice of any loss, claim or damage, liability or
action, giving rise to claim for indemnification under this Section 7, the
person claiming indemnification shall promptly notify the person against whom
indemnification is sought (unless such person is also a party to such
complaint, notice, claim or action) of such complaint, notice, claim or action,
and such indemnifying person shall have the right to investigate and defend any
such loss, claim, damage, liability or action, provided that such indemnifying
person shall not settle any such claim or action unless (i) such settlement is
approved by the person claiming indemnification, or (ii) such settlement
provides for a full, general release from all claims against the person
claiming indemnification.  The person claiming indemnification shall have the
right to employ separate counsel in any such action and to participate in the
defense thereof but the fees and expenses of such counsel shall not be at the
expense of the person against whom indemnification is sought and the
indemnifying person shall not be obligated to indemnify any person for any
settlement of any claim or action effected without the indemnifying person's
consent, which consent will not be unreasonably withheld.






                                                                         Page 8

                 Section 8.       Marketing Restrictions.

                 8.1      If:

                 A.       a registration is to be made pursuant to a
         registration notice under Section 1 or Section 2 of this Agreement,
         and

                 B.       the offering proposed to be made by the Holder or
         Holders for whom such registration is to be made is to be an
         underwritten public offering, and

                 C.       the managing underwriters of such public offering
         furnish a written opinion that the total amount of Registrable Common
         to be included in such offering would exceed the maximum number of
         shares of Common (as specified in such opinion) which can be marketed
         at a price reasonably related to the current market value of such
         Common and without otherwise materially and adversely affecting such
         offering,

then the rights of the Holders, of the holders of other Securities having the
right to include Common in such registration and of the Company to participate
in such offering shall be in the following order of priority:

                 First: the Holders shall be entitled to participate in such
         offering to the extent of such maximum number of shares of Common, or
         of the aggregate number of shares of Registrable Common that all such
         Holders shall have requested be registered, whichever is less, pro
         rata among themselves in accordance with the number of shares of
         Registrable Common which each such Holder shall have requested be
         registered; and then

                 Second:  if such maximum number of shares of Common exceeds
         the aggregate number of shares of Registrable Common that all such
         Holders shall have requested be registered, the Company and all
         holders of other Securities having the right to include such
         Securities in such registration shall be entitled to participate in
         accordance with the relative priorities, if any, that shall exist
         among them and the Company;

and no Securities (issued or unissued) other than those registered and included
in the underwritten offering shall be offered for sale or other disposition by
the Company or any Holder in a transaction which would require registration
under the Securities Act for a period beginning thirty (30) days prior to the
anticipated effective date of such registration statement and continuing until
ninety (90) days after the effective date of the registration statement filed
in connection with such registration or such earlier time consented to by the
managing underwriter, but in no event shall such period exceed 120 days.  In
the future, the Company shall require each person to whom the Company grants
such rights, as a condition precedent to the effectiveness of such rights, to
agree to be bound by the foregoing restriction on distribution after conclusion
of the underwritten offering.






                                                                         Page 9
<PAGE>   10
                 8.2      If:

                 A.       any Holder of Preferred or Registrable Common
         requests inclusion of Registrable Common in a registration statement
         filed by the Company under Section 3 of this Agreement, and

                 B.       the offering proposed to be made is to be an
         underwritten public offering, and

                 C.       the managing underwriters of such public offering
         furnish a written opinion that the total amount of securities to be
         included in such offering would exceed the maximum amount of
         Securities (as specified in such opinion) which can be marketed at a
         price reasonably related to the then current market value of such
         Securities and without materially and adversely affecting such
         offering,

then the rights of the Holders, of the holders of other Securities having the
right to include such Securities in such registration and of the Company to
participate in such offering shall be in the following order of priority:

                 First:  the Company; and then

                 Second:  the Holders shall be entitled to participate in such
         offering, pro rata among themselves in accordance with the number of
         shares of Registrable Common which each such Holder shall have
         requested be registered; and then

                 Third:  all other holders (including the Company, if such
         registration shall have been requested by a person other than the
         Company) of Securities having the right to include such Securities in
         such registration shall be entitled to participate in accordance with
         the relative priorities, if any, that shall exist among them;

and no Securities (issued or unissued) other than those registered and included
in the underwritten offering shall be offered for sale or other disposition by
the Company or any Holder in a transaction which would require registration
under the Securities Act for a period beginning thirty (30) days prior to the
anticipated effective date of such registration statement and continuing until
ninety (90) days after the effective date of the registration statement filed
in connection with such registration or such earlier time consented to by the
managing underwriter, but in no event shall such period exceed 120 days.

                 8.3      In connection with any offering involving an
underwriting of Registrable Common pursuant to Section 3 of this Agreement, the
Company shall not be required to include any of the Registrable Common of a
Holder in such offering unless such Holder agrees to the terms of the
underwriting agreed to between the Company and the underwriter or underwriters
selected by the Company, provided that no such agreement shall add to the
indemnities or affect the priorities set forth in this Agreement.






                                                                        Page 10

                 Section 9.       Sale of Preferred to Underwriter.
Notwithstanding anything in this Agreement to the contrary, in lieu of
converting any Preferred to Common prior to or simultaneously with the filing
or the effectiveness of any registration statement filed pursuant to this
Agreement, the Holder of such Preferred may sell such Preferred to the
underwriter of the offering being registered upon the undertaking of such
underwriter to (i) convert such Preferred into Common before making any
distribution pursuant to such registration statement, and (ii) include such
Common among the Securities being offered pursuant to such registration
statement.  The Company agrees to cause the Common issuable on conversion of
such Preferred to be issued within such time as will permit the underwriter to
make and complete the distribution contemplated by the underwriting and to
register the Preferred in any registration statement so that the Holder may
make the sale described in the first sentence of this Section 9.

                 Section 10.      Lockup Agreement.  Each Holder and the
Company agrees in connection with any registration of any of the Company's
Securities that, upon the request of the Company or the underwriters managing
any underwritten offering of the Company's Securities, he or it will not sell,
make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Securities of the Company (other than the Securities
included in the registration) without the prior written consent of the Company
or such underwriters, as the case may be, for such period of time beginning
thirty (30) days prior to the anticipated effective date of such registration
statement and continuing until ninety (90) days after the effective date of
such registration statement, but in no event shall such period exceed one
hundred and twenty (120) days.

     of the Company or such underwriters, as the case may be, for such period
     of time beginning thirty (30) days prior to the anticipated effective date
     of such registration statement and continuing until one hundred eighty
     (180) days after the effective date of such registration statement,
     but in no event shall such period exceed two hundred and ten (210) days."

     pages hereof, any subsequent legal or beneficial owner of Preferred or
     Registrable Common who becomes a party to this Agreement in accordance
     with Section 12 hereof, and any subsequent parties who agree to be
     bound by this Agreement, as amended from time to time."

     2.  Continuing Effect.  Except as otherwise specifically provided in this

                              SUPPLY AGREEMENT
     Agreement effective March 15, 1997 ("Effective Date"), by and between 
Nanophase Technologies Corporation, 453 Commerce Street, Burr Ridge, Illinois 
50521 ("NTC") and Schering-Plough HealthCare Products, Inc., 3030 Jackson 
Avenue, Memphis TN 38151 ("S-P"). NTC and S-P are collectively referred to as 
the "Parties" and individually as a "Party."

                                   PURPOSE
     S-P desires to promote and market Nanophase (TM) Zinc Oxide ("NZO") in 
consumer products marketed for footcare products including odor, wetness and 
athlete's foot applications. NZO has not previously been used in these 
products. S-P wants to develop a market for those products which products are 
to contain NZO.  In order to justify the expense and effort required to create 
a market for products containing NZO S-P requires a limited period of exclusive
supply of NZO from NTC.

     Accordingly, S-P and NTC hereby agree to the following terms and 
conditions:

                                  ARTICLE I
                         TERM, TERRITORY, AND OPTION

     1.1 Territory. The territory of the Agreement will be the United States,
Canada, Mexico and Puerto Rico.

     1.2 Term. The term of this Agreement shall be four (4) years commencing on
the Effective Date.
                                 ARTICLE II
                        NTC'S SUPPLY RESPONSIBILITIES

     2.1 Supply of NZO. NTC will exclusively supply NZO for S-P and S-P shall
exclusively purchase from NTC, all of S-P's requirements for NZO ingredients
for footcare products including odor, wetness and athlete's foot applications,
to be sold within the food, mass merchandiser and drug store classes of trade.
However, S-P's exclusivity outlined in this Section #2.1 shall be contingent
upon S-P's purchase of NZO in a quantity of at least one thousand (1,000)
kilograms ("Kg") in each three (3) month period, commencing July 1, 1997.

     2.2 Exception to Exclusivity. NTC may continue to supply NZO to other 
current and new customers; however, it is understood and agreed that NTC will 
inform the customers, in writing, that NZO may not be used in products marketed
for use in the categories listed in 2.1 unless the use is previously known to 
NTC or, if NTC's customer discloses the present use at the time of notification.
     2.3 Priority. NTC agrees to give first supply priority to S-P's orders for
NZO.

<PAGE>   2
                                 ARTICLE III
                           S-P'S RESPONSIBILITIES
     3.1 Forecasts and Purchase Orders. S-P will provide to NTC, on a quarterly
basis, a forecast estimating S-P's or S-P's contract manufacturer's monthly
purchase requirements (the "Forecast"), along with the expected delivery dates
for the succeeding twelve (12) month period (the "Delivery Date"). S-P or S-P's
contract manufacturer will issue firm purchase orders for each delivery no
later than thirty-five (35) days prior to the requested delivery date. The
leadtime agreed upon by the parties is thirty (30) days after receipt of order.

                                 ARTICLE IV
                                   PRICING

     4.1 Pricing. The parties hereby agree that the supply price for NZO shall 
be in accordance with Exhibit A which indicates the price for various 
quantities of NZO to be purchased. Terms of payment are net thirty (30) days 
from date of Bill of Lading ship date. For purposes of this Agreement, 
acceptance will occur only after S-P has completed such quality control testing
as S-P deems necessary to verify the conformity of NZO to the specifications as
set forth in Exhibit B.

     4.2 Basis for Product Price. The prices set forth above include all 
materials, manufacturing, packaging of NZO, and such quality control measures 
as required by this Agreement.

     4.3 The price for NZO set forth in Section #4.1 shall be effective through
December 31, 1998 unless raw material price increases are greater than five
percent (5%) in which case price must be reviewed and negotiated by the
parties.  Thereafter, the price of the NZO for a calendar year shall be subject
to annual review pursuant to a written request at intervals of not less than
twelve (12) months by the parties to take into account any increase or decrease
in NTC's labor, raw material and/or component costs directly allocable to the
manufacture of NZO. The first such review should occur three (3) months prior
to January 1, 1999. It is the intent of the parties to have all annual price
increases or decreases be effective on January 1 of each year, which will
reflect any increase or decrease in cost for the preceding calendar year. NTC
shall use reasonable efforts to obtain competitive prices for raw materials and
services from a qualified third party vendor. All calculations for overhead or
labor costs made pursuant to this Section #4.3 shall be in accordance with
NTC's accounting principles. If an agreement cannot be reached as to the price
for NZO, S-P shall have the right to terminate this Agreement.

                                                         
                                      2
<PAGE>   3
     4.4 Maximum Price Increase. Notwithstanding the foregoing, in no event
shall the percentage of any price increase based on increases in NTC's
manufacturing costs exceed the lesser of the percentage increase in the cost of
raw materials or five percent (5%) which increase shall be substantiated by
NTC.

     4.5 Records. NTC shall maintain records with respect to its costs, 
obligations and performance under this Agreement.  Specifically, but without 
limitation, NTC shall maintain all records reasonably necessary to support 
financial accounting entries and tax requirements in the Territory. All such 
records shall be maintained for a period of not less than two (2) years 
following termination of this Agreement or such longer period as may be 
required by law, rule or regulation. Prior to the destruction of any record 
available for review, notice shall be provided to S-P, and S-P shall have the 
right to request and retain said record.

                                  ARTICLE V
                                  DELIVERY

     5.1 Risk of Loss. Delivery of each order of NZO shall be F.O.B., Approved
Facility (as defined in Section 7.1 of this Agreement), freight collect (call
S-P's Transportation Department to arrange for pickup or carrier to contact) or
such other shipping point agreed upon between the parties. S-P shall arrange
via its designated common carrier transportation of the NZO to S-P's specified
plant or other designated destination. Title to and risk of loss of the NZO
shall pass to S-P at the time of delivery to the specified carrier. NTC shall
promptly bill S-P for all NZO tendered and invoices shall be accompanied by the
certificate of analysis for each lot of NZO delivered.

     5.1(a) Identification. Each NZO ship case and pallet shall be clearly
marked in accordance with S-P's instructions.

     5.1(b) All NZO shall be packaged in a manner to avoid breakage and
contamination.

     5.2 Schedule. NTC shall schedule the timely manufacturing and delivery of
the NZO pursuant to S-P's purchase orders. For purposes of this Agreement, a
timely shipment shall be a shipment delivered by NTC at the F.O.B. point no
later than five (5) days prior to the dock date. The parties agree that for
purposes of delivery, time is of the essence.

     5.3 Delay and Failure to Supply.  Should NTC, at any time during the course
of this Agreement, have reason to believe that it will be unable to meet S-P's
requested delivery dates, NTC will promptly notify S-P in writing setting forth
the reasons for the delay. In connection therewith,
                                                                          
                                       3
<PAGE>   4
     (a) In the event NTC, for any reason (including events of excused 
performance as set forth in this Agreement) has been unable to supply S-P's 
binding purchase orders for NZO meeting the warranties contained in Paragraph 
5.6 of this Agreement, without being able to supply ninety percent (90%) of such
binding purchase orders within an additional ten (10) days, (including any new
orders in such period), then NTC, upon written notice to S-P may establish
secondary sources of supply for the purchase requirements set forth in
Paragraph 7.4 of this Agreement.

     (b) In the event S-P has reason to believe that NTC or NTC's secondary 
sources for any reason (including events of excused performance as set forth 
in this Agreement) will not be able to supply S-P's purchase orders for NZO 
meeting the warranties contained in this Agreement, S-P may notify NTC in 
writing requesting adequate assurances of future performance and that NTC will 
be able to supply S-P with at least ninety percent (90%) of the purchase orders
to be delivered in accordance with this Agreement. NTC shall, within ten (10) 
days, respond in writing to S-P's request for adequate assurances of future
performance stating whether NTC is or is not able to supply S-P with at least
ninety percent (90%) of the purchase orders. If NTC fails to live up to its
assurances, then S-P may also seek and/or establish a secondary supplier.

     (c) In the event NTC anticipates that in the future NTC or any NTC 
secondary source will be unable to supply S-P's purchase orders for NZO meeting
the warranties contained in this Agreement, with no prospect of being able to
provide ninety percent (90%) of such purchase orders within an additional
thirty (30) days, then NTC shall notify S-P in writing to that effect. Upon
such notification, S-P may, if it chooses, temporarily suspend this Agreement
and produce the NZO for its own purchase requirements as set forth in this
Agreement. At such time as NTC or a NTC secondary source is able to resume
production, with NTC exercising diligent efforts to resume production as
quickly as possible, NTC shall notify S-P in writing and continue and/or
reinstate this Agreement with NTC supplying S-P's requested requirements for
NZO for the term remaining in this Agreement.

     5.4 Acceptance/Rejection. All shipments of NZO are subject to S-P's 
inspection prior to acceptance. In the event that S-P believes that any batch 
of NZO does not meet the previously agreed-upon NZO Specifications (as set forth
in Exhibit B), S-P shall give NTC prompt notice of its rejection of such batch,
including reasons for rejection. Upon receipt of any such notice, within 
twenty (20) days following receipt of notice of rejection by S-P, NTC shall 
deliver a new batch of NZO to replace the rejected batch. NTC will destroy or 
dispose of the entire rejected batch in question at its sole expense.
                                                                          
                                       4
<PAGE>   5
     5.5 Overruns. Should the delivered NZO exceed the binding P. O. by more 
than five (5) percent, S-P may return the excess to NTC without payment, with 
all shipping costs to be paid by NTC.

     5.6 Warranty. NTC warrants that at the time of delivery of the NZO at the
F.O.B. point of delivery, the NZO shall (i) have been manufactured in
accordance with GMPs and all other applicable laws, rules, regulations or

regulations related to the manufacture of the NZO in accordance with the
Specifications. NZO shall be manufactured at the Approved Facility and the
location thereof shall not be changed without S-P's written consent.

     (b) Exhibit C attached hereto describes all products which are     
manufactured on machinery or equipment used to manufacture NZO. NTC shall 
notify S-P in writing of any potential additional products to Exhibit C. If S-P
identifies a potential problem of cross-contamination arising from the products
listed on Exhibit C or any additions thereto, the parties will meet to address
the cross-contamination issue. At S-P's request, NTC shall provide S-P with all
information and written procedures necessary to examine and resolve the
cross-contamination issue. Until the parties mutually satisfactorily resolve
the cross-contamination issue, NTC shall not manufacture products on machinery
or equipment used to manufacture the NZOs which S-P believes could cause
cross-contamination for the NZOs. [Include, if applicable.] 

     7.2 Specifications Amendments. The NZO Specifications shall be amended or 
supplemented to comply with GMPs and may be amended or supplemented (including,
without limitation, for the purpose of incorporating improvements) from time to
time upon the written request of S-P. In the event such amendment requires 
additional actual cost to NTC for the manufacture of the NZO, S-P and NTC shall
agree on the additional compensation therefore. 

     7.3 Quality Control Program. NTC shall maintain a quality control program  
consistent with GMP, as required by the Regulatory Authorities in the
Territory, which program, as amended or supplemented, shall be provided to S-P
from time to time.

discovery of any batch failure which could result in NTC's inability to meet
S-P's requested delivery dates, or of learning of any failure of any batch of
NZO to meet standards set forth in the S-P Manufacturing Know-how.

     7.8 Notification of Inspections. NTC agrees to notify S-P immediately of   
any inquiries, notifications, or inspection activity by any Regulatory
Authority in regard to the NZO. NTC shall provide a reasonable description to
S-P of any such governmental inquiries, notifications or inspections promptly
after such visit or inquiry, but in less than two (2) calendar days, NTC shall
furnish to S-P, (a) within two (2) days after receipt, any report or
correspondence issued by the Regulatory Authority in connection with such visit
or inquiry, including but not limited to, any FDA Form 483 Establishment
Inspection Reports, warning letters and (b) prior to responding to a Regulatory
Authority, copies of any and all proposed responses or explanations relating to
items set forth above, in each case purged only of trade secrets of NTC that
are unrelated to the obligations under this Agreement or are unrelated to the
NZO.

     7.9 Inspection by S-P. S-P shall have the right during normal business 
hours (including, without limitation, during production or after normal business
hours if reasonably requested and in connection with a production run that
commenced during the normal business hours) and with reasonable advance notice
to visit NTC's Approved Facility for the purpose of observing the
manufacturing, packaging, testing, and warehousing of the NZO, and to inspect
for compliance with GMPs and other applicable regulatory requirements. S-P
shall also have the right to be present at an inspection referenced in Section
8.8 above.

      7.10 Environmental and Other Laws and Regulations. In carrying out its
obligations under this Agreement, NTC shall comply with all applicable
environmental and health and safety laws, regulations, ordinances, guidelines
and policies (current or as amended or added) (hereinafter "Laws"), and shall
be solely responsible for determining how to carry out these obligations.
Notwithstanding any other provision in this Agreement to the contrary, nothing
provided to NTC by S-P, by way of materials, specifications, processing
information or otherwise, is meant to diminish this as NTC's sole
responsibility. NTC also represents and warrants that it has the appropriate
skills, personnel, equipment, permits, approvals or the like necessary to
perform its services or provide materials under this Agreement in compliance
with all applicable Laws. NTC shall immediately notify S-P, in writing, or any
circumstances, including the receipt of any notice, warning, citation, finding,
report or service of process or the occurrence of any release, spill, upset, or
discharge, relating to NTC's compliance with this Section 7.10 or which may
impose environmental liability upon NTC.  NTC's noncompliance with this Section
7.10 is considered a material breach of this Agreement. S-P reserves the right  
to conduct an environmental inspection of NTC's facility or facilities,  during
normal business hours and with reasonable advance notice, for the  purpose of
determining compliance with this Section 7.10. S-P will share the  results of
any environmental inspection with NTC. Such inspection, if it  occurs, does not
relieve NTC of its sole obligation to comply with all  applicable Laws and does
not constitute a waiver of any right otherwise  available to S-P.

     7.11 Inspection and Acceptance. S-P will inspect the NZO and conduct any
quality control testing it deems necessary to verify conformity to raw material
specifications as referenced in this Agreement. Product rejected by S-P will be
returned to NTC, at NTC's cost, for credit & replacement.

                            RENEWAL AND TERMINATION

     9.1 Renewal of the Agreement. S-P may on sixty (60) days written notice to
NTC notify S-P's intentions to renegotiate extending the term of this Agreement
listed in Paragraph 1.2(a).  NTC will renegotiate renewal in good faith upon
mutual agreement.

     9.2 Termination by Non-Renewal. Either party may terminate this Agreement 
by giving the other party written notice of termination at least ninety (90) 
days prior to the end of the

initial term or any renewal period.

     9.3 Termination by S-P. S-P shall have the right to terminate this 
Agreement if:

     9.3.1 there is a change in control of NTC. For purposes of this provision,
a "change in control" shall mean the acquisition of fifty percent (50%) or more
of the assets or outstanding common stock or other equity interest of NTC by a
non-affiliated third party. NTC shall notify S-P in writing at least sixty (60)
days prior to any "change in control".  S-P shall notify NTC in writing within
thirty (30) days of such notification whether or not S-P elects to terminate
this Agreement. S-P warrants that it will make a reasonable effort to continue
this Agreement with any controlling parties and will not arbitrarily terminate
it under this paragraph 9.3.1.

     9.3.2 NTC files a petition in bankruptcy, or enters into an arrangement 
with its creditors, or applies for or consents to the appointment of a receiver
or trustee, or makes an assignment for the benefit of creditors, or suffers or
permits the entry of an order adjudicating it to be bankrupt or insolvent. In
the event this Agreement is terminated under Section 9.3.2, all rights and
licenses granted under this Agreement by NTC to S-P are, and shall otherwise be
deemed to be, for purposes of Section 365(n) of the Bankruptcy Code, licenses
of rights to "intellectual property" as defined under Section 101(52) of the
Bankruptcy Code. The parties agree that S-P, as a licensee of such rights under
this Agreement, shall retain and may fully exercise all of its rights and
elections under the Bankruptcy Code. The parties further agree that, in the
event of the commencement of a bankruptcy proceeding by or against NTC under
the Bankruptcy Code, S-P shall be entitled to a complete duplicate of (or
complete access to, as appropriate) any such intellectual property and all
embodiments of such intellectual property upon written request therefore by
S-P. Such intellectual property and all embodiments thereof shall be promptly
delivered to S-P (i) upon any such commencement of a bankruptcy proceeding upon
written request therefore by S-P, unless NTC elects to continue to perform all
of its obligations under this Agreement or (ii) if not delivered under (i)
above, upon the rejection of this Agreement by or on behalf of NTC upon written
request therefore by S-P.

     9.4 Termination for Material Default. Upon default by a party in the
performance of any material obligation in this Agreement which results in
significant harm to the non-defaulting party, the non-defaulting party may give
notice in writing to the party in default and the defaulting party shall have
sixty (60) days thereafter to cure the default.  Except as qualified in the
last sentence of this paragraph, if the defaulting party does not cure or
institute measures to substantially cure such default within sixty (60) days
and diligently complete the cure within an 

                                                                          
                                       10
<PAGE>   11
additional sixty (60) days, the non-defaulting party may terminate this
Agreement by providing notice of intent to terminate which shall take effect
ten (10) days following the receipt by the defaulting party of such notice.
Termination under this Article shall not relieve either party of any obligation
existing upon the date of termination or relieve the defaulting party from
liability for breach of this Agreement.

     9.5 Effect of Termination. Expiration or termination of the Agreement 
shall not relieve the parties of any obligation accruing prior of such 
expiration or termination, and the provisions of Sections 6.5 and Articles 12, 
13 and 14, shall survive the expiration of the Agreement. Any expiration or 
early termination of this Agreement shall be without prejudice to the rights of
either party against the other accrued or accruing under this Agreement prior
to termination.

     9.6 No Waiver. The failure of either party to terminate this Agreement by
reason of the breach of any of its provisions by the other party shall not be
construed as a waiver of the rights or remedies available for any subsequent
breach of the terms and provisions of this Agreement.

                                   ARTICLE X
                       FORCE MAJEURE; INABILITY TO SUPPLY

     10.1 Force Majeure. Neither party shall be responsible for any failure to
comply with the terms of this Agreement where such failure is due to force
majeure, which shall include, without limitation, fire, flood, explosion,
strike, labor disputes, labor shortages, picketing, lockout, transportation
embargo or failures or delays in transportation, strikes or labor disputes
affecting supplies, or acts of God, civil riot or insurrection, acts of the
government, or judicial action. Specifically excluded from this definition are
those acts of any governmental agency, or judicial action, which could have
been avoided by compliance with such laws or regulations, publicly available
and reasonably expected to be known by either party. Upon the cessation of any
cause operating to excuse performance of either party under this Section 9.1,
this Agreement shall continue in full force and effect unless or until
otherwise terminated pursuant to this Agreement and each party shall endeavor
to resume its performance hereunder as quickly as possible if such performance
is delayed or interrupted by reason of any cause set forth herein. If one or
more of said causes set forth herein is asserted by either party as a basis of
that party's nonperformance, the other party shall have the right to terminate
this Agreement forthwith by giving written notice to that effect prior to the
resumption of performance.

                              COMPLIANCE WITH LAWS

     All NZO manufactured by NTC pursuant to this Agreement shall be subject to
all applicable Federal, State and local laws, including, but not limited to, the
Fair Labor Standards Act of 1938, as amended and, unless NTC is exempted, the
President's Executive Order No. 11246, Section 202, relating to equal
employment opportunities and all subsequent additions or amendments thereto,
and the Immigration Reform Act of 1986.

                                  ARTICLE XII
                         INDEMNIFICATION AND INSURANCE

     12.1 NTC's Indemnification Obligation. NTC agrees to indemnify and hold 
S-P, its agents and employees harmless from and against all claims, liabilities
(including product liability), costs, damages, losses, judgments for damages or
expenses (including reasonable attorney's fees) caused by, arising out of, or
resulting from i) NTC's negligent acts and/or omissions relating to the
manufacture of NZO and ii) NTC's performance of its obligations hereunder
(including any environmental contamination or release of hazardous substance,
or hazardous wastes to the environment caused by NTC, its Approved Facilities,
its employees, agents or contractors), its failure to comply with this
Agreement, or any laws and regulations applicable to such performance.

     12.2 S-P's Indemnification Obligation. S-P agrees to indemnify and hold 
NTC, its agents and employees harmless from and against all claims, liabilities,
costs, damages, losses, judgments for damages or expenses (including reasonable
attorneys' fees) caused by, arising out of, or resulting from S-P's negligent
acts and/or omissions relating to the marketing, distribution and sale of the
NZO.

     12.3 Notice of Suit. The indemnified party agrees to give the indemnifying
party prompt notice in writing of the institution of any suit, including any
suit or claim asserted or made by any governmental authority having
jurisdiction, and the indemnified party agrees to permit the indemnifying party
to have control and conduct of the defense of such suit, and give the
indemnifying party all needed information in the indemnified parties possession
and all authority and assistance necessary to enable the indemnifying party to
carry on the defense of such suit and any appeal from a judgment or decree
rendered therein.

     12.4 Insurance. NTC represents and warrants that during the term of this
Agreement and any renewals or extensions, it shall maintain the types and
amounts of insurance set forth below:

Liability/Completed Operations coverage with a minimum limit of one (1) million
dollars ($1,000,000) each claim.

     (ii) NTC will provide a certificate of insurance for their current 
coverage.  NTC shall provide thirty (30) days' written notice of cancellation 
or material change in the policy to S-P, if possible.

bound by any compromise of claims, demand, judgments or causes of action made 
without its prior written consent.

     12.6 Notice of Claims. Each party agrees to give the other prompt written
notice of any claims made, including any claims asserted or made by any
governmental authority having jurisdiction, for which the other might be liable
under the foregoing indemnification together with the opportunity to defend,
negotiate and settle such claims.

                                  ARTICLE XIII
                           TRADE NAMES AND TRADEMARKS

     13.1 S-P and NTC hereby acknowledge that neither party has, and shall not
acquire, any interest in any of the other party's trademarks, tradenames,
tradedress or copyrights appearing on the labels or packaging materials for the
NZO unless otherwise expressly agreed.

                                  ARTICLE XIV
                                CONFIDENTIALITY

     14.1 Both NTC and S-P recognize that know-how of a party disclosed to the 
other party pursuant to this Agreement or developed as a result of 
Manufacturing NZO carried out pursuant to this Agreement, is of proprietary 
value and is to be considered highly confidential ("Proprietary Information"). 
NTC and S-P shall use only in accordance with this Agreement and shall not 
disclose to any third party any Proprietary Information, without the prior 
written consent of the other party. The foregoing obligations shall survive 
the expiration or termination of this Agreement for a period of twenty (20) 
years. These obligations shall not apply to Proprietary Information that:
 
     (a) is known by the receiving party at the time of its receipt, and not 
through a prior disclosure by the disclosing party, as documented by business 
records;

<PAGE>   14
     (b) is at the time of disclosure or thereafter becomes published or 
otherwise part of the public domain without breach of this Agreement by the 
receiving party;

     (c) is subsequently disclosed to the receiving party by a third party who 
has the right to make such disclosure;

     (d) is developed by the receiving party independently of Proprietary
Information or other information received from the disclosing party and such
independent development can be properly demonstrated by the receiving party;

     (e) is disclosed to governmental or other regulatory agencies in order to
obtain patents or to gain approval to conduct clinical trials or to market NZO,
but such disclosure may be only to the extent reasonably necessary to obtain
such patents or authorizations;

     (f) is necessary to be disclosed to sublicensees, agents, consultants,
Affiliates and/or other third parties for the research and development,
manufacturing and/or marketing of NZO (or for such parties to determine their
interest in performing such activities) in accordance with this Agreement on
the condition that such third parties agree to be bound by the confidentiality
obligations contained in this Agreement, provided that the term of
confidentiality for such third parties shall be no less than twenty (20) years;
or

     (g) is required to be disclosed by law or court order, provided that 
notice is promptly delivered to the other party in order to provide an 
opportunity to seek a protective order or other similar order with respect to 
such Proprietary Information and thereafter discloses only the minimum 
information required to be disclosed in order to comply with the request, 
whether or not a protective order or other similar order is obtained by the 
other party.  

     Nothing herein shall be interpreted to prohibit S-P from publishing the 
results of its studies in accordance with industry practices.

     14.2 No Publicity. A party may not use the name of the other party in any
publicity or advertising and, may not issue a press release or otherwise
publicize or disclose any information related to this Agreement or the terms or
conditions hereof, without the prior written consent of the other party. The
parties shall agree on a form of initial press release that may be used by
either party to describe this Agreement. Nothing in the foregoing, however,
shall prohibit a party from making such disclosures to the extent deemed
necessary under applicable federal or state securities laws or any rule or
regulation of any nationally recognized securities exchange; in such event,
however, the disclosing party shall use

and, where applicable, shall request confidential treatment to the extent
available.

                                 ASSIGNMENT

     16.1. Neither this Agreement nor any or all of the rights and obligations 
of a party hereunder shall be assigned, delegated, sold, transferred, 
sublicensed (except as otherwise provided herein) or otherwise disposed of, by 
operation of law or otherwise, to any third party other than an Affiliate of 
such party, without the prior written consent of the other party, and any 
attempted assignment, delegation, sale, transfer, sublicense or other 
disposition, by operation of law or otherwise, of this Agreement or of any 
rights or obligations hereunder contrary to this Section #16.1 shall be a 
material breach of this Agreement by the attempting party, and shall be void 
and without force or effect; provided, however, S-P and NTC may, with consent 
and said consent will not be unreasonably withheld, assign the Agreement and    
its rights and obligations hereunder to an Affiliate or in connection with the 
transfer or sale of all or substantially all of its assets related to the 
division or the subject business, or in the event of its merger or 
consolidation or change in control or similar transaction. This Agreement shall
be binding upon, and inure to the benefit of, each party, its Affiliates, and 
its permitted successors and assigns. Each party shall be responsible for the 
compliance by its Affiliates with the terms and conditions of this Agreement.

                                  ARTICLE XVII
                                 GOVERNING LAW

     17.1 This Agreement shall be governed, interpreted and construed in 
accordance with the laws of the State of Tennessee, without giving effect to 
conflict of law principles.

                                 ARTICLE XVIII
                                 MISCELLANEOUS

     18.1 Waiver. A waiver of any breach or any provision of this Agreement 
shall not be construed as a continuing waiver of other breaches of the same or 
other provisions of this Agreement.

     18.2 Independent Relationship. Nothing herein contained shall be deemed to
create an employment, agency, joint venture or partnership relationship between
the parties hereto or any of their agents or employees, or any other legal
arrangement that would impose liability upon one party for the act or failure
to act of the other party. Neither party shall have any power to enter into any
contracts or commitments or to incur any liabilities in the name of, or on
behalf of, the other party, or to bind the other party in any respect
whatsoever.

     18.3 Export Control. This Agreement is made subject to any restrictions
concerning the export of products or technical information from the United
States of America which may be imposed upon or related to NTC or S-P from time
to time by the government of the United States of America. Furthermore, S-P
agrees that it will not export, directly or indirectly, any technical
information acquired from NTC under this Agreement or any products using such
technical information to any country for which the United States government or
any agency thereof at the time of export requires an export license or other
governmental approval, without first obtaining the written consent to do so
from the Department of Commerce or other agency of the United States government
when required by an applicable statute or regulation.

     18.4 Entire Agreement; Amendment. This Agreement, including the Exhibits 
and Schedules hereto, sets forth the complete, final and exclusive agreement and
all the covenants, promises, agreements, warranties, representations,
conditions and understandings between the parties hereto and supersedes and
terminates all prior agreements and understandings between the parties. There
are no covenants, promises, agreements, warranties, representations, conditions
or understandings, either oral or written, between the parties other than as
are set forth herein and therein. No subsequent alteration, amendment, change
or addition to this Agreement shall be binding upon the parties unless reduced
to writing and signed by an authorized officer of each party.

     18.5 Severability. If any provision of this Agreement is declared invalid 
or unenforceable by a court having competent jurisdiction, it is mutually agreed
that this Agreement shall endure except for the part declared invalid or
unenforceable by order of such court. The parties shall consult and use their
best efforts to agree upon a valid and enforceable provision which shall be a
reasonable substitute for such invalid or unenforceable provision in light of
the intent of this Agreement.

     18.6 Counterparts. This Agreement shall become binding when any one or more
counterparts hereof, individually or taken together, shall bear the signatures
of each of the parties hereto. This Agreement may be executed in any number of
counterparts, each of which shall be an original as against either party whose
signature appears thereon, but all of which taken together shall constitute but
one and the same instrument.

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

VENTILATION REQUIREMENTS: Use with adequate ventilation to meet the exposure
                          limits listed in Section 2. Where the exposure limit
                          is or may be exceeded, use NIOSH approved respiratory
                          protection. Select the appropriate dust respirator
                          based on the actual or potential concentration of 
                          airborne dust from this product. Comply with all
                          appropriate OSHA, EPA, state and local regulations.

RESPIRATORY PROTECTION:   High efficiency particle respirator

PROTECTIVE GLOVES:        Rubber or plastic

EYE/FACE PROTECTION:      ANSI approved safety goggles

SECTION 9 - SPECIAL PRECAUTIONS
- -------------------------------------------------------------------------------

HANDLING AND STORAGE:   Handle in hoods or other well ventilated areas only. 
                        Take care not to cause airborne dust to be generated
                        out side of ventilated areas. Keep container tightly
                        closed and  store in a cool, dry, well ventilated area.
                        Wash thoroughly after use. Comply with all OSHA, EPA,
                        State and local regulations. Magnesium violently
                        reduces zinc oxide when heated, resulting in an
                        explosion. Mixtures of chlorinated rubber and zinc
                        oxide explode when heated above 215 degrees C.

OTHER PRECAUTIONS:      Have available: lab coats, aprons, flame and chemical
                        resistant coveralls, high efficiency particle
                        respirators, continuously-flushing eyewash, safety 
                        drench shower, hygienic facilities for washing. Use as
                        appropriate to the task being performed or the situation
                        being addressed.

(the "Agreement") among Nanophase Technologies Corporation, an Illinois
corporation (the "Company"), and the persons executing a counterpart of this

                            PRELIMINARY STATEMENT
                                      
                                      
     The Company and the Holders have previously entered into that certain
Shareholders' Agreement dated as of November 21, 1991, as amended by a First
Amendment to Shareholders' Agreement dated February 8, 1993 (collectively, the
"Original Agreement"), which provides certain restrictions on the transfer of
Shares of the Company now or hereafter issued, provides for certain agreements
with respect to the management of the Company, and otherwise provides for
certain matters regarding their relations as shareholders.

     Concurrently with the execution of this Agreement, the Company and the
Holders propose to execute that certain Series D Preferred Stock Purchase
Agreement (the "Series D Purchase Agreement") pursuant to which certain of the
Holders will purchase additional securities of the Company.  To induce the
Holders to execute the Series D Purchase Agreement, the Company and the Holders
agree to amend and restate the Original Agreement as follows.


                                  AGREEMENT

market maker pursuant to Rule 144 under the Securities Act (or any similar rule
then in force).

transactions where a lien is created against the Shares.

     2.  Restrictions on Transfers of Shares.  No current or future Shareholder
shall Transfer any Shares owned by it or him except in accordance with the

           (ii) Three (3) members designated jointly by the Series C Preferred

           (iii) One (1) member designated jointly by each Holder who shall

<PAGE>   3


     (b) In each case where the holders of Common, the Preferred Holders or
Preferred Holders holding a designated class of Preferred shall have the right
to designate a director or directors jointly, such right shall be exercised
upon the vote or written consent of the holders of Common or the Preferred
Holders acting as a class, as the case may be, holding a majority of the
relevant class of Shares held by all of the holders of such class of Shares at
the time such designation is to be made, provided that a holder of Common or a
Preferred Holder shall not participate in the selection of directors as
provided in this Section 3 from and after the time such holder of Common or
Preferred Holder holds less than the sum of (i) 40% of the Preferred purchased
by such Person pursuant to the Series B Purchase Agreement, plus (ii) 40% of
the Preferred purchased by such Person pursuant to the Series C Purchase
Agreement, plus (iii) 40% of the Preferred purchased by such Person pursuant to
the Series D Purchase Agreement, plus (iv) 40% of the New Securities which such
Person may be entitled to purchase pursuant to Section 6 below.

     (c) The parties agree to take all actions necessary to implement the
provisions of this Section 3, including without limitation the voting of their
shares of Common or Preferred, the execution of written consents, the calling
of special meetings, the waiving of notice, and the attendance of meetings.
All parties specifically agree that the provisions of this Section 3 constitute
a voting agreement under Section 7.70 of the Illinois Business Corporation Act,
and, in connection therewith, each party hereby grants the secretary of the
Company an irrevocable proxy to cast all of such party's votes for directors
selected in accordance with this Section 3.

     (d)  The Company shall reimburse all reasonable expenses of the persons
serving as directors pursuant to Section 3 hereof incurred in serving as

such service and attendance is in person or by telephone), including (i)
coach-class airfare for attendance at Board meetings by out-of-town directors,
and (ii) reasonable expenses incurred in connection with the performance of
other services on behalf of the Company for which prior approval has been

aggregate, at least 4 1/2% or more of the total Shares outstanding from time to
time, with at least five days' prior written notice of each meeting of the
Board, and such Holder or a Person designated by such Holder may attend any
such meeting as an observer.  The Company will also furnish each such Holder
with copies of all actions of the Board taken without a meeting, whether by
written consent or otherwise.  Notwithstanding the foregoing, (i) such Holder
or other Person shall agree to hold in confidence and trust as fiduciary all
information furnished to or learned by such Holder or Person pursuant to this
subsection (e), and (ii) the Company may exclude such Holder or other Person
from any portion of any such meeting, and may decline to furnish any such
information, to the extent that counsel to the Company deems necessary in order
to protect the attorney-client privilege between the Company and its counsel.

     4.  Right of First Refusal.

     (a) Transfer Notice.  Except as otherwise provided in Sections 5 and 8
below, if any Shareholder desires to Transfer all or any part of its Shares
("Sale Shares"), such Shareholder shall deliver written notice thereof to the
Company and each other Shareholder specifying the number of Shares which such
Shareholder desires to Transfer and the purchase price and other terms thereof
(a "Transfer Notice").  The purchase price for the Sale Shares may be payable
either in cash or in the form of an unsecured promissory note, and in no other
medium of exchange or form.

     (b) Company Option.  Upon the delivery of such Transfer Notice, the
Company shall have an option, exercisable for twenty (20) days after the date
of receipt of such Transfer Notice, to buy any or all of the shares of the Sale
Shares from the Selling Shareholder at the price and on the terms set forth in
the Transfer Notice.

     (c) Shareholder Option.  If the Company does not exercise its option to
buy all of the Sale Shares within such period, then each non-selling
Shareholder shall have the right to purchase any or all of the remaining Sale
Shares upon the terms set forth in the Transfer Notice, which right may be
exercised by written notice (an "Exercise Notice") given to the Company and the
selling Shareholder within fifteen (15) days after the date on which Company's
option shall expire or, if earlier, the date on which the Company shall notify
such non-selling Shareholders that the Company will not exercise its option
under Section 4(b).  In the event that the number of the Shares specified in
the Exercise Notices exceed the number of Sale Shares, then each Shareholder
delivering an Exercise Notice shall be entitled to purchase the percentage of
Sale Shares obtained by dividing the number of shares of Common (treating each
share of Preferred as though converted to Common) held by such Shareholder by
the number of shares of Common (treating each share of Preferred as though
converted to Common) held by all Shareholders delivering Exercise Notices.

     (d) Remaining Shares.

     (i)  If the Company or the Company and the Shareholders do not elect to
purchase any of the Sale Shares, then the selling Shareholder shall be free,
for a period of ninety (90) days thereafter, to consummate the Transfer of the
Sale Shares on terms no less favorable to itself than as set forth in the
Transfer Notice.

     (ii)  If the Company or the Company and the Shareholders together elect to
purchase some, but not all, of the Sale Shares, then the Selling Shareholder
shall have the option (A) to consummate the Transfer of the Sale Shares, as set
forth in clause (i) above, as though the Company and the Shareholders had not
elected to purchase any of the Sale Shares, or (B) to sell to the Company and
the electing Shareholders as the case may be, the portion of Sale Shares
elected by such parties, and Transfer the balance of such Sale Shares to the
Transferee set forth in the Transfer Notice on the terms set forth therein.  If
the Transfer of the Sale Shares is not consummated within the ninety (90) day
period referenced in clause (i) above, the provisions of this Section 4 shall
once again apply to such Shares.




<PAGE>   5


     (iii)  Notwithstanding clause (ii) above, if a Shareholder shall have
elected to purchase not less than its Pro Rata Share (as defined below) of the
Sale Shares in accordance with this Section 4, and shall have so notified the
selling Shareholder in such Shareholder's Election Notice, the selling
Shareholder shall be required to exercise the option set forth in clause
(ii)(B) above with respect to the Pro Rata Share of such Shareholder.  For
purposes of this clause (iii), the term "Pro Rata Share" means the product of
(A) the total number of Sale Shares, and (B) a fraction having a numerator
equal to the number of Shares held by the Shareholder exercising its rights
under this subsection (iii), and a denominator equal to the number of Shares
held by all Shareholders (other than the selling Shareholder) as of the date of
the Transfer Notice.

     (e) Mechanics of Sale.  The sale of the Sale Shares (the "Sale Share
Closing") to the Company, any electing Shareholders and third parties, as the
case may be, shall occur at 10:00 a.m. central standard time, at the principal
offices of the Company, on (i) the 20th business day following the expiration
of the exercise period set forth in Section 4(c) above, if the Company or any
Shareholders exercise their respective options for all of the Sale Shares, (ii)
the day specified in the Transfer Notice (which is within the ninety (90) day
period referenced in subsection (d)(i) above), if neither the Company nor any
other Shareholders are party to the Sale Share Closing, or (iii) such other
place or time (but not date) as the parties to the Sale Share Closing may
mutually agree.  At the Sale Share Closing, the purchasers shall respectively
deliver the appropriate amount of consideration in the form set forth in the
Transfer Notice, and the selling Shareholder shall deliver a certificate or
certificates representing the Sale Shares, free and clear of all liens, claims
or encumbrances whatsoever (other than those imposed by this Agreement).

     (f) Transferees Bound.  In the event of any Transfer under this Section 4,
the Shares so Transferred shall be subject to the provisions of this Agreement,
and the persons acquiring the Shares shall, as a condition precedent to the
acquisition of the Shares, execute a counterpart copy of this Agreement and
agree to be bound thereby, and shall also pay any costs incurred by the Company
as a result of such Transfer.

     5.  Permitted Transfers.  Notwithstanding anything contained herein to
the contrary, any Shareholder, without having complied with the provisions of
Section 4 hereof, may Transfer any or all of the Shares standing in his or its
name to or for the benefit of any of (i) in the case of a Shareholder who is a
natural person, upon his death to his spouse, an immediate ancestor or
descendant, or a trust created for the primary benefit of any of the foregoing
permitted transferees (provided that such trust, if it provides for a secondary
or contingent beneficiary, shall provide for a second or contingent beneficiary
to whom a Transfer could have been made under this Section 5), or (ii) in the
case of a Shareholder which is a corporation or partnership, and only to the
extent permitted by applicable laws or regulations without registration of the
Shares so Transferred, any affiliate of the Shareholder (which, for purposes of
this Section 5 shall mean any Person controlled by, controlling, or under
common control with such Shareholder), any general or limited partner of a
Shareholder which is a partnership, or any person or entity holding capital
stock entitling such person or entity to a vote for the election of directors
of a Shareholder which is a corporation.  In the event of any Transfer under
this Section 5, the Shares so Transferred




<PAGE>   6


shall be subject to the provisions of this Agreement, and the persons
acquiring the Shares shall, as a condition precedent to the acquisition of the
Shares, execute a counterpart copy of this Agreement and agree to be bound
thereby, and shall also pay any costs incurred by the Company as a result of
such Transfer.  Any person to whom Shares may be Transferred pursuant to this
Section 5 is referred to as a "Permitted Transferee".

     6.  Right of First Refusal - New Securities.

     (a) Meaning of "Preferred" and "Preferred Holder".  For the purposes of
this Section 6, the term "Preferred" shall be deemed to include (i) any
Conversion Stock received on the exercise of the conversion right of the
Preferred and the Warrants, and (ii) with respect to Richard Siegel, the number
of shares of Common held by Siegel as of any time of determination of the
number of outstanding shares of Preferred.

     (b) Grant of Right.  Subject to Section 6(g) hereof, each Preferred Holder
shall have the right (the "Right of First Refusal"), at such Preferred Holder's
option, to purchase any New Securities that the Company may from time to time
propose to sell and issue at the price and upon the general terms specified in
the Notice of Intent (as defined below) regarding such New Securities and
otherwise on the terms of this Section 6.

     (c) Corporation's Notice of Intent.  If the Company proposes to issue and
sell New Securities, the Company shall give each Preferred Holder written
notice ("Notice of Intent") of such intention, describing the type of New
Securities proposed and the price and general terms upon which the Company
proposes to issue such New Securities.

     (d) Right of First Refusal - First Round.  Each Preferred Holder shall
have thirty (30) days from the date such Preferred Holder receives a Notice of
Intent to agree, by written notice delivered to the Company within such thirty
day period (a "New Securities Exercise Notice"), to purchase up to such
Preferred Holder's "Pro Rata Share" of the New Securities described in such
Notice of Intent.  For purposes of this Section 6(d), the "Pro Rata Share" of
each Preferred Holder shall be that percentage of the New Securities obtained
by dividing the number of shares of Preferred held by such Preferred Holder by
the total number of shares of Preferred held by all Preferred Holders.

     (e) Right of First Refusal - Second Round.  If some but not all Preferred
Holders deliver a New Securities Exercise Notice in which they elect to
purchase their full pro rata share of such New Securities to the Company within
the thirty (30) day period provided, then upon the completion of such thirty
(30) day period the Company shall give each Preferred Holder who shall have
delivered such a New Securities Exercise Notice (a "New Securities Purchaser")
written notice (the "Remaining Shares Availability Notice") of the amount of
New Securities remaining not committed to Preferred Holders hereunder (the
"Remaining Shares").  Each New Securities Purchaser shall have ten (10) days
from the date such New Securities Purchaser receives such Remaining Shares
Notice to agree to purchase any or all of the Remaining Shares, which right
shall be exercisable by written notice to the Company ("Remaining Shares
Exercise Notice") delivered within such ten (10) day period (each New
Securities Purchaser giving a Remaining Shares Exercise Notice shall be
referred to herein as 



<PAGE>   7


a "Remaining Shares Purchaser").  In the event that the sum of the Remaining
Shares specified in the Remaining Shares Exercise Notices received by the
Company shall exceed the number of Remaining Shares, then each Remaining Shares
Purchaser shall be entitled to purchase that percentage of Remaining Shares
obtained by dividing the number of shares of Preferred held by such Remaining
Shares Purchaser by the total number of shares of Preferred held by all
Remaining Shares Purchasers.

     (f) Mechanics of Sales.  The Rights of First Refusal of each Preferred
Holder shall expire as to particular New Securities if such Preferred Holder
shall not have delivered a New Securities Exercise Notice or Remaining Shares
Exercise Notice, respectively, to the Company within the thirty (30) day period
provided in Section 6(d) or the ten (10) day period provided in Section 6(e),
respectively.  In the event that Preferred Holders fail to agree to purchase
all of a proposed issue of New Securities within the periods provided above,
the Corporation may sell, or enter into a binding agreement to sell, any New
Securities that the Preferred Holders have not agreed to purchase at a price
and upon general terms no more favorable to the purchasers than those specified
in the Notice of Intent with regard to such New Securities, at any time during
(and only during) the 180 days following the expiration of the thirty (30) day
period provided in Section 6(d) above or, if a Remaining Shares Notice was
required as to such New Securities, the ten (10) day period provided in Section
6(e) above (provided, in the case of a binding agreement to sell, that the sale
pursuant to such agreement is closed within ninety (90) days after the
execution of such agreement).  If not all of a proposed issue of New Securities
is committed to be purchased, by Preferred Holders or others, within such
180-day period, the Company shall not be bound to sell any of such New
Securities.  The sale of any New Securities to Preferred Holders shall be
closed at the same place as and simultaneously with the sale of such New
Securities to any other purchasers or, if Preferred Holders are purchasing the
entire issue of New Securities, at the principal office of the Company 45 days
after Preferred Holders have agreed to buy all of such New Securities, or such
other place or date as the parties to such transaction may mutually agree.

     (g) Going Public.  The Rights of First Refusal created by this Section 6
shall terminate upon the consummation of the Company's Qualified Initial Public
Offering.

     7.  Market Stand-Off.  In connection with any underwritten public offering
by the Company of its equity securities pursuant to an effective registration
statement filed under the Securities Act, no Shareholder shall Transfer for
value or otherwise agree to Transfer any Shares without the prior written
consent of the Company or its underwriters, for such period of time beginning
ninety (90) days prior to the anticipated effective date of such registration
statement and continuing until one hundred twenty (120) days after the
effective date of such registration statement.  In order to enforce this
Section 7, the Company may impose stop-transfer instructions with respect to
the Shares until the end of the applicable stand-off period.

     8.  Other Agreements Concerning Shares.

     (a)  At any time on or after December 1, 1997, but prior to December 1,
1999, Preferred Holders holding at least a majority of the Series C Preferred
and the Series D Preferred then outstanding may, but shall not be obligated to,
jointly (and not severally) give one (1) written notice (a "Put Notice") to the
Company and to the other Series C Preferred Holders and Series D Preferred
Holders not joining in the Put Notice offering to put to the Company, for the
price, on the terms and conditions and otherwise in accordance with the
provisions of this Section 8, all of the Series C Preferred Shares and Series D
Preferred Shares owned by such Preferred Holders at the time of the Put Notice
(the "Put Offer").

     (b)  Any holder of Series C Preferred or Series D Preferred not having
joined in the Put Notice may, but shall not be obligated to, notify the Company
of its desire to participate in the Put Offer with respect to such holder's
Series C Preferred and Series D Preferred by delivering written notice to the
Company on or before the 30th day following the date of the Put Notice.

     (c)  The Company shall, within five (5) business days of the expiration of
the thirty (30) day period referenced in (b) above, notify in writing all of
the Series C Preferred and Series D Preferred Holders having elected to
participate in the Put Offer of the time and date for the consummation of the
initial purchase contemplated by the Put Offer, which shall be no later than
the one hundred and eightieth (180th) day following the date on which the
Company gives such written notice, which shall occur at the executive offices
of the Company.  At such time, the participating Preferred Holders shall
deliver certificates representing all of their Series C Preferred and Series D
Preferred free and clear of any and all liens, claims and encumbrances
whatsoever, and the Company shall deliver to each participating Series C
Preferred and Series D Preferred Holders the appropriate consideration therefor
evidenced by the Company's promissory note in such amount payable to such
Holder in three (3) equal annual installments on each of the first three
anniversaries of the issuance of such note, together with interest on the
outstanding principal balance of such note at the rate of 8% per annum
calculated on the basis of a 365 day year, and payable annually as of each
principal repayment date.

     (d)  The purchase price to be paid by the Company for each share of
Series C Preferred put to the Company pursuant to this Section 8 shall equal
the price originally paid for such share, plus a deemed cumulative dividend of
8% per annum from the date of original purchase of the Series C Preferred
through the date of repurchase specified above.  The purchase price to be paid
by the Company for each share of Series D Preferred put to the Company pursuant
to this Section 8 shall equal the price originally paid for such share, plus a
deemed cumulative dividend of 8% per annum from the date of original purchase
of the Series D Preferred through the date of repurchase specified above.  If
the funds of the Corporation legally available therefor shall be insufficient
to discharge the Company's obligation to consummate the Put Offer in full,
funds to the extent legally available therefor shall be employed to purchase
the maximum number of Series C Preferred Shares and Series D Preferred Shares
that can be purchased with such funds, ratably from the Holders participating
in such transaction in proportion to the preferential amounts each such Holder



<PAGE>   9


would be entitled to receive pursuant to Article 4(B)3(a) of the
Articles of Incorporation.  Thereafter, the Company shall redeem shares of
Series C Preferred and Series D Preferred from such Holders as funds become
legally available therefor, ratably from such Holders in the proportions set
forth in the preceding sentence, until all shares of Series C Preferred and
Series D Preferred originally subject to the Put Offer shall have been
purchased.

     (e)  Each Shareholder, whether or not participating in the Put Offer,
hereby agrees that, for purposes of any and all agreements to which it may be a
party or by which it is bound, it shall be deemed to have consented to the
consummation of the Put Offer so long as such transaction is initiated and
consummated in accordance with all of the provisions of this Section 8.

     9.  General Proxy.

     (a)  The Department hereby constitutes and appoints each Preferred Holder,
as to such Preferred Holder's Pro Rata Proxy Share (defined below) of the
Shares now or hereafter owned by the Department, as the Department's proxies,
and hereby authorizes each Preferred Holder to represent it, as to such Shares,
at all meetings of shareholders with all powers the Department would have if it
were present, and to vote such Shares in all matters, submitted to the
Shareholders of the Company for a vote.

     (b)  The proxies granted to each Preferred Holder are coupled with an
interest, and shall be irrevocable.  Such proxies shall automatically expire on
the sooner to occur of (i) an amendment to the Investment Act to allow the
Department to exercise voting rights with respect to such Shares, or (ii) the
Transfer by the Department of all of its Shares to any Person who is not
prohibited from exercising voting rights as to such Shares.

     (c)  For purposes of this Section 9, the term "Pro Rata Proxy Share"
means, as to any Preferred Holder, the product of (A) the total number of
Shares held by the Department as of any time of determination, and (B) a
fraction having a numerator equal to the number of Shares held by such
Preferred Holder, and a denominator equal to the number of Shares held by all
Preferred Holders (other than the Department) as of the time of determination.

     10.  Legend.  So long as this Agreement shall remain in force, all
certificates now or hereafter representing the Shares shall bear the following
legend:

     "The shares of stock which are evidenced by this certificate may not be
     sold, transferred, pledged or otherwise disposed of by the registered
     owner thereof, and no votes may be cast or consents given on behalf
     thereof, except in accordance with and subject to the terms and conditions
     of an Amended and Restated Shareholders' Agreement dated as of March 16,
     1994, among the corporation and the stockholders thereof, a copy of which
     Agreement is on deposit with the Secretary of the corporation.  No
     transfer of such Shares shall be effective unless made in accordance with
     such Agreement, and each holder of this certificate agrees to be bound by
     such Agreement."



<PAGE>   10


When the restrictions on transfer imposed by this Agreement shall terminate,
any Shareholder shall be entitled to receive from the Company, upon surrender
of their existing certificates representing such Shares, without cost or
expense, one or more new certificates representing such Shareholder's Shares
not bearing the above legend.

     11.  Stock Dividends.  If a stock dividend of shares of the same or a
different class as the Shares is paid, or if the Shares of any portion thereof
are exchanged for Shares of stock of the Company of a different class or for
voting trust certificates evidencing the beneficial interest possessed in said
shares or if any other event (such as a stock split, reclassification, or
similar event) shall occur so that the shareholders of the Company shall
receive additional or replacement shares of stock of the Company (whether of
the same or different class), then such stock of the same or a different class,
or such voting trust certificates, as the case may be, shall thereupon become
subject to the provisions of this Agreement upon the same terms and conditions
as the Shares originally covered by this Agreement.

     12.  Only Record Holder Entitled to be Recognized.  Only the record holder
of Shares shall be entitled to receive dividends or to exercise any other right
as a Shareholder, and the mere existence or exercise of any option hereunder
shall not give the party holding or exercising such option any rights as a
Shareholder prior to the time that a stock certificate has been duly issued to
it by the Company or otherwise delivered to it by the transferring Shareholder
in accordance with this Agreement.

     13.  Termination.  This Agreement and all restrictions on the transfer of
Shares created hereby shall terminate upon the completion of the Company's
Qualified Initial Public Offering, and shall not apply to any shares sold in
the Company's Qualified Initial Public Offering (provided that the market
stand-off provisions of Section 7 shall remain in full force and effect as set
forth in such Section).  The termination of this Agreement for any reason shall
not affect any right or remedy existing hereunder prior to the effective date
of termination hereof.

     14.  Enforcement Costs.  In any instance wherein any party hereto is
required to take legal action to enforce the provisions hereof, the prevailing
party shall be entitled to recover, in addition to all other damages allowed at
law or in equity, all costs and expenses, including reasonable attorneys' fees,
incurred in enforcing the provisions hereof.

     15.  Notices.  All notices which may or are to be given hereunder shall be
effective when received, shall be in writing and shall be given by hand
delivery, sent by telecopy or facsimile transmission, confirmed by the
recipient, or sent by certified or registered mail, postage prepaid, return
receipt requested, to the party at such party's address as set forth below:

converted to Common for this purpose).  Notwithstanding the foregoing, no
amendment shall confer any greater rights, or impose any additional
restrictions, on any shares of Preferred as compared to any other shares of
Preferred, or on any shares of Common as compared to any other shares of
Common, or on any Shareholder as compared to any other Shareholder, without the
prior written consent of all of the parties to this Agreement.

thereof and all defined terms shall be deemed to refer to the masculine,
