                                  RISK FACTORS

      A purchase of our common stock is speculative and involves a high degree
of risk. You should carefully consider the risks described below together with
all of the other information included or incorporated by reference in this
prospectus before making an investment decision. The risks and uncertainties
described below are not the only ones we face. If any of the following risks
actually occur, our business, financial condition or operating results could be
harmed. In such case, the trading price of our common stock could decline and
you could lose all or part of your investment.

We have experienced losses in the current and prior years and we anticipate that
we will continue to generate losses for the foreseeable future.

      Our operations to date have not been profitable. As of December 31, 2000
we had an accumulated deficit of $20.4 million. We expect to continue operating
at a loss during the first quarter of 2001. These losses are primarily
attributable to low margins in our injection molding and laser processing
businesses and the significant costs and expenses associated with manufacturing
and marketing many of our other laser technology services as well as our general
and administrative expenses. Other factors that could adversely affect our
operating results include:

      o     the cost of manufacturing scale-up and production;

      o     introduction of new products and product enhancements by us or our
            competitors;

      o     changes in applied photonics technologies; and

      o     changes in general economic conditions.

We cannot assure you that our revenues will increase sufficiently to offset our
operating costs or that, even if they do, that our operations will ever be
profitable.

Going Concern Limitation.

      The report of our independent auditors with respect to our financial
statements for the year ended December 31, 2000 incorporated by reference in
this report states that there is substantial doubt regarding our ability to
continue as a going concern. There can be no assurance that our existing
operations will not continue to generate negative cash flows. However, we
believe that increased cash flows from operations during the current year,
coupled with fixed costs of sales leverage, and cost saving measures that have
been implemented will satisfy our working capital needs.

We are highly leveraged, which increases our operating deficit and makes it
difficult for us to grow.

      As of December 31, 2000 we had current liabilities, including trade
payables, of $6.6 million, and long-term liabilities of $2.9 million and a
working capital deficit of $3.8 million. We continue to experience working
capital shortages that materially impair our business operations and growth
strategy. If we continue to incur debt and experience working capital
limitations, our business, operations and financial condition will be materially
adversely affected. At December 31, 2000, we were not in compliance with certain
covenants under our borrowing facilities. Accordingly, the lender may, upon
notice, declare the entire unpaid principal balance due and payable.



                                       3



We depend on Cockfield to provide us with capital under the equity line of
credit agreement.

      Our immediate financing needs depend on our ability to sell shares of our
common stock to Cockfield under the equity line of credit agreement. There are a
number of factors that could adversely affect our ability to sell shares of our
common stock to Cockfield under the equity line of credit agreement, including:

      o     Cockfield's ability or willingness to perform its obligations under
            the agreement;

      o     The trading price and volume of our stock. If the market price is
            low or the volume is thin, we may not be able to sell a sufficient
            number of shares to meet our capital requirements; and

      o     Our ability to sell more than 19.99% of our currently outstanding
            shares to Cockfield requires stockholder approval under the Nasdaq
            SmallCap Market corporate governance rules. There is no assurance
            that we will receive this approval.

For a description of the equity line of credit agreement see "Recent
Developments -- Equity Line of Credit" beginning on page 15 of this prospectus.

Our stockholders may experience significant dilution as a result of stock
issuances under the equity line of credit agreement.

      Under the equity line of credit agreement we will sell shares of our
common stock to Cockfield at a price that may be below the market price of our
stock at that time. As a result, these sales will dilute the interests of our
existing stockholders. In addition, as the price of our common stock decreases,
we will be required to issue more shares of our common stock for any given
dollar amount invested by Cockfield. The more shares that are issued under the
equity line of credit, the more our shares will be diluted and the more our
stock price may decrease. This may encourage short sales, which could place
further downward pressure on the price of our common stock. Furthermore, for the
life of any outstanding options and warrants, the holders will have the
opportunity to profit from a rise in the price of the underlying common stock.
When the holders of these options and warrants exercise their rights to acquire
shares of our common stock, the interests of the other stockholders will be
diluted. In addition, the holders of the options and warrants can be expected to
exercise their options and warrants at a time when we would, in all likelihood,
be able to obtain additional capital by an offering of our unissued common stock
on terms more favorable to us than those provided by such options or warrants.

We may require additional financing in the future, which may not be available on
acceptable terms.

      Depending on the amount of money we raise under the equity line of credit
agreement with Cockfield and our ability to generate additional revenues, we may
require additional funds to expand our production capability, continue to
develop new applications for our direct write technology and for working capital
and general corporate purposes. At this time, we do not believe that product
sales will reach the level required to sustain our operations and growth plans
in the near term. Therefore, we are actively pursuing additional financing
alternatives. We cannot assure you that any additional financing will be
available or, if available, will be offered on acceptable terms. The equity line
of credit agreement limits our ability to sell our securities to third parties
at a discount to the market price during its term. Accordingly, if we need
additional capital but are unable to draw down under the equity line of credit
agreement for any reason, our access to capital may be limited. In addition, any
additional equity financing may be dilutive to stockholders, and debt
financings, if available, may involve restrictive covenants that further limit
our ability to make decisions that we believe will be in our best interests. In



                                       4



the event we cannot obtain additional financing on terms acceptable to us when
required, our operations will be materially adversely affected and we will have
to cease or substantially reduce operations.

Some of our products and services are at an early stage of development and may
not achieve market acceptance.

      Currently, our primary focus is to develop new commercial applications for
GCSEL, diode laser and laser driven direct write technologies. Many of the
benefits of GCSEL, diode laser and laser driven direct write technologies are
not widely known. Therefore, we anticipate that we will need to educate our
target markets to generate demand for our services and, as a result of market
feedback, we may be required to further refine these services. In order to
persuade potential customers to purchase our services, we will need to overcome
industry resistance to, and suspicion of, new technologies. In addition,
developing new applications for these technologies and other new technologies
will require significant further research, development, testing and marketing
prior to commercialization. We cannot assure you that commercial applications of
these technologies can be successfully developed, marketed or produced.

Some of our current products and services have not been commercially successful.

      Our laser materials processing and mold building products and services do
not generate a significant amount of revenue, even though they have been
available for some time. In addition, most of our revenue from these businesses
is generated from a limited number of customers. We cannot assure you that these
customers will continue to purchase these products and services or that we will
be able to expand the market for these products and services. Our resources
available for sales and marketing activities are limited. Therefore, any
material delay, retooling, cancellation or reduction in orders from the
customers who purchase these products and services could have a material adverse
affect on our business, operations and financial condition.

We have limited marketing and sales capabilities and must make sales in
fragmented markets.

      Our future success depends, to a great extent, on our ability to
successfully market our products and services. We currently have limited sales
and marketing capabilities and experience and we will need to hire qualified
sales and marketing personnel, develop additional sales and marketing programs
and establish sales distribution channels in order to achieve and sustain
commercial sales of our products. Qualified sales and marketing personnel in
this area are in short supply and we cannot assure you that we will be able to
hire them. In addition, our ability to successfully market our products and
services is further complicated by the fact that our principal markets, laser
photonics, telecommunications, aerospace and medical components, are highly
fragmented. Consequently, we will need to identify and successfully target
particular market segments in which we believe we will have the most success.
These efforts will require a substantial, but unknown, amount of effort and
resources. We cannot assure you that any marketing and sales efforts undertaken
by us will be successful or will result in any significant product sales.

We depend on the aerospace, laser photonic, telecommunications and medical
device industries, which continually produce technologically advanced products.

      A majority of our sales are to companies in the aerospace, laser photonic,
telecommunications and medical device industries, which are subject to rapid
technological change and product obsolescence. If our customers are unable to
create products that keep pace with the changing technological environment and
market demand, their products could become obsolete and the demand for our
services could decline significantly. If we are unable to offer cost-effective,
quick-response manufacturing



                                       5



services to customers, demand for our services will also decline. This would
have a material adverse affect on our business, operations and financial
condition.

Our industry is intensely competitive, which may adversely affect our operations
and financial results.

      All our markets are intensely competitive and numerous companies offer
conventional and laser driven products and services that compete with our
products and services. We anticipate that competition for our products and
services will continue to increase. Most of our competitors have substantially
greater capital resources, research and development staffs, manufacturing
capabilities, sales and marketing resources, facilities and experience. These
companies, or others, could undertake extensive research and development in
laser technology and related fields that could result in technological changes.
Many of these companies also are primary customers for various components, and
therefore have significant control over certain markets that we have targeted.
In addition, we may not be able to offer prices as low as some of our
competitors because those competitors may have lower cost structures as a result
of their geographic location or the services they provide. Our inability to
provide comparable or better products and services at a lower cost than our
competitors could cause our net sales to decline. We cannot assure you that our
competitors will not succeed in developing technologies in these fields which
will enable them to offer laser services more advanced and less costly than
those we offer or which could render our technologies obsolete.

Our products and services are subject to industry standards, which increases
their cost and could delay or bar their commercial acceptance.

      Since some of our products and services are used in the telecommunications
industry, they must comply with the Bellcore Testing standards for traditional
equipment and/or Bluetooth standards for wireless devices. These standards
govern the design, manufacture and marketing of these items. If we fail to
comply with these standards, we will not be able to sell our products. We may
encounter significant delays or incur additional costs in our efforts to comply
with these industry standards.

We depend on our relationship with third parties to develop and commercialize
new products.

      Our strategy for research and development and for the commercialization of
our products contemplates a continuing relationship with various publicly and
privately funded consortia and our existing relationships will continue with
strategic partners, OEMs, licensees and others. We depend on these associations
and relationships not only to underwrite our research and development efforts,
but also for product testing and to create markets for our products and
services. We cannot assure you that our existing relationships will continue or
the extent to which the parties to such arrangements will continue to allocate
time of resources to these strategic alliances. Similarly, we cannot assure you
that we will be able to enter into new arrangements in the future. In addition,
we cannot assure you that such agreements will progress to a production phase
or, if production commences, that we will receive significant revenues as a
result of these relationships. We cannot assure you that these parties, or any
future partners, will perform their obligations as expected or that any revenue
will be derived from such arrangements.

We have only limited manufacturing capabilities and our inability to continually
manufacture products on a cost-effective basis would harm our business.

      We have limited production facilities and limited experience in
manufacturing our product offerings. To the extent any of our existing or future
products must be produced in commercially reasonable quantities, we will have to
either develop that expertise quickly or outsource that function. Developing
manufacturing capability is an expensive and time-consuming endeavor and we do
not have



                                       6



the resources that are required for a full-scale manufacturing capability.
Therefore, in all likelihood we will have to engage a third party to manufacture
our products for us. In that event, we will depend on the manufacturer to
produce high-quality products based on our specifications, on time and within
budget. If we are unable to manufacture products in sufficient quantities and in
a timely manner to meet customer demand ourselves or by others, our business,
financial condition and results of operations will be materially adversely
affected.

We depend on our intellectual property rights to provide us with a competitive
advantage.

      Our ability to compete successfully depends, in part, on our ability to
protect our products and technologies under United States and foreign patent
laws, to preserve trade secrets and other proprietary information and
technologies, and to operate without infringing the proprietary rights of
others. We cannot assure you that patent applications relating to our products
or potential products will result in patents being issued, that any issued
patents will afford adequate protection or not be challenged, invalidated,
infringed or circumvented, or that any rights granted will give us a competitive
advantage. Furthermore, we cannot assure you that others have not independently
developed, or will not independently develop, similar products and/or
technologies, duplicate any of our product or technologies, or, if patents are
issued to, or licensed by, us, design around such patents. We cannot assure you
that patents owned or licensed and issued in one jurisdiction will also be
issued in any other jurisdiction. In addition, we cannot assure you that we can
adequately protect our proprietary technology and processes that we maintain as
trade secrets. If we are unable to develop and adequately protect our
proprietary technology and other assets, our business, financial condition and
results of operations will be materially adversely affected.

We depend on the continued services of our key personnel.

      Our future success depends, in part, on the continuing efforts of our
senior executive officers, Clifford G. Brockmyre II, Thomas Mueller, J. Terence
Feeley and Bruce J. Garreau, who conceived our strategic plan and who are
responsible for executing that plan. The loss of any of these key employees may
adversely affect our business. At this time we do not have any term "key man"
insurance on any of these executives other than a $1.7 million policy on
Clifford G. Brockmyre II. If we lose the services of any of these senior
executives, our business, operations and financial condition could be materially
adversely affected.

We may have difficulties in managing our growth.

      Our future growth depends, in part, on our ability to implement and expand
our financial control systems and to expand, train and manage our employee base
and provide support to an expanded customer base. If we cannot manage growth
effectively, it could have material adverse effect on our results of operations,
business and financial condition. In 1999 we made two acquisitions and opened a
new facility in Illinois. Acquisitions and expansion involve substantial
infrastructure and working capital costs. We cannot assure you that we will be
able to integrate our acquisitions and expansions efficiently. Similarly, we
cannot assure you that we will continue to expand or that any expansion will
enhance our profitability. If we do not achieve sufficient revenue growth to
offset increased expenses associated with our expansion, our results will be
adversely affected.

We must attract, hire and retain qualified personnel.

      As we continue to develop new products and as our business grows,
significant demands will be placed on our managerial, technical, financial and
other resources. One of the keys to our future success will be our ability to
attract, hire and retain highly qualified engineering, marketing, sales and



                                       7



administrative personnel. Competition for qualified personnel in these areas is
intense and we will be competing for their services with companies that have
substantially greater resources than we do. We cannot assure you that we will be
able to identify, attract and retain employees with skills and experience
necessary and relevant to the future operations of our business. Our inability
to retain or attract qualified personnel in these areas could have a material
adverse effect on our business and results of operations.

We face potential product liability claims.

      The sale of our telecommunications, aerospace and medical products and
services will involve the inherent risk of product liability claims by others.
We maintain product liability insurance coverage. However, we cannot assure that
the amount and scope of our existing coverage is adequate to protect us in the
event that a product liability claim is successfully asserted. Moreover, we
cannot assure you that we will continue to maintain the coverage we currently
have. Product liability insurance is expensive, subject to various coverage
exclusions and may not always be obtainable on terms acceptable to us.

Our stock price is volatile and could be further affected by events not within
our control.

      The trading price of our common stock has been volatile and will continue
to be subject to:

      o     Volatility in the trading markets generally;

      o     Significant fluctuations in our quarterly operating results;

      o     Announcements regarding our business or the business of our
            competitors;

      o     Changes in prices of our or our competitors' products and services;

      o     Changes in product mix; and

      o     Changes in revenue and revenue growth rates for us as a whole or for
            geographic areas, and other events or factors.

      Statements or changes in opinions, ratings or earnings estimates made by
brokerage firms or industry analysts relating to the markets in which we operate
or expect to operate could also have an adverse effect on the market price of
our common stock. In addition, the stock market as a whole has from time to time
experienced extreme price and volume fluctuations which have particularly
affected the market price for the securities of many small cap companies and
which often have been unrelated to the operating performance of these companies.

The price of our common stock may be adversely affected by the possible issuance
of shares of our common stock under the equity line of credit agreement and as a
result of the exercise of outstanding warrants and options.

      In addition to the 668,014 shares of our common stock covered by this
prospectus, we have previously registered 3,300,000 shares of common stock to
the equity line of credit agreement and all of the shares of our common stock
reserved for issuance under our stock option plan. To date, we have granted
options covering 984,429 of these shares. In addition, we have issued warrants
covering 709,975 shares of common stock. We have agreed with certain of these
holders to register the shares underlying their warrants. As a result of the
actual or potential sale of these shares into the market, our common stock price
may decrease. In that event not only would you lose a portion of your
investment, but we would probably find it more difficult to obtain additional
financing.



                                       8



Concentration of ownership

      As of April 1, 2001, our chief executive officer, Clifford G. Brockmyre
II, is our largest stockholder, owning approximately 27% of our issued and
outstanding shares of our common stock. Assuming all of the shares of our common
stock covered by this prospectus and the equity line of credit agreement
discussed under "Recent Developments" beginning on page 15 of this prospectus
are issued, Mr. Brockmyre will own 13%. In either event, Mr. Brockmyre, as a
result, effectively controls all our affairs, including the election of
directors and any proposals regarding a sale of the Company or its assets or a
merger.

Some provisions in our charter documents and bylaws may have anti-takeover
effects.

      Our certificate of incorporation and bylaws contain provisions that may
make it more difficult for a third party to acquire us, with the result that it
may deter potential suitors. For example, our board of directors is authorized,
without action of the stockholders, to issue authorized but unissued common
stock and preferred stock. The existence of undesignated preferred stock and
authorized but unissued common stock enables us to discourage or to make it more
difficult to obtain control of us by means of a merger, tender offer, proxy
contest or otherwise.

Absence of dividends to shareholders.

      We have never declared a dividend on our common stock. We do not
anticipate paying dividends on the common stock in the foreseeable future. We
anticipate that earnings, if any, will be reinvested in the expansion of our
business.

We have agreed to limitations on the potential liability of our directors.

      Our certificate of incorporation provides that, in general, directors will
not be personally liable for monetary damages to the company or our stockholders
for a breach of fiduciary duty. Although this limitation of liability does not
affect the availability of equitable remedies such as injunctive relief or
rescission, the presence of these provisions in the certificate of incorporation
could prevent us from recovering monetary damages.

We must maintain compliance with certain criteria in order to maintain listing
of our shares on the Nasdaq market.

      Our common stock is currently traded on the Nasdaq SmallCap Market. In
order to maintain this listing, we are required to meet certain requirements
relating to our stock price and our net tangible assets. If we fail to meet
these requirements, our stock could be delisted. We have received a series of
letters from Nasdaq that we failed to satisfy the minimum net tangible asset
listing requirements for the SmallCap Market. As a result of private placements
and other equity transactions consummated after December 31, 2000, we believe we
are currently in compliance with the net tangible asset requirement. However, we
cannot assure you that Nasdaq will agree or that we will continue to satisfy the
Nasdaq SmallCap Market listing requirements. If our stock is delisted, it will
trade on the OTC Bulletin Board or in the "pink sheets" maintained by the
National Quotation Bureau Incorporated. As a consequence of such delisting, an
investor could find it more difficult to dispose of or to obtain accurate
quotations as to the market value of our securities. Among other consequences,
delisting from Nasdaq may cause a decline in the stock price and difficulty in
obtaining future financing.



                                       9



The liquidity of our stock could be severely reduced if it becomes classified as
"penny stock".

      The Securities and Exchange Commission has adopted regulations which
generally define a "penny stock" to be any non-Nasdaq equity security that has a
market price (as therein defined) of less than $5.00 per share or with an
exercise price of less than $5.00 per share. If our securities were subject to
the existing rules on penny stocks, the market liquidity for our securities
could be severely adversely affected. For any transaction involving a penny
stock, unless exempt, the rules require substantial additional disclosure
obligations and sales practice obligations on broker-dealers where the sale is
to persons other than established customers and accredited investors (generally,
those persons with assets in excess of $1,000,000 or annual income exceeding
$200,000, or $300,000 together with their spouse). For transactions covered by
these rules, the broker-dealer must make a special suitability determination for
the purchase of the common stock and have received the purchaser's written
consent to the transaction prior to the purchase. Additionally, for any
transaction involving a penny stock, unless exempt, the rules require the
delivery, prior to the transaction, of a risk disclosure document mandated by
the Commission relating to the penny stock market. The broker-dealer also must
disclose the commissions payable to both the broker-dealer and the registered
representative, current quotations for the securities and, if the broker-dealer
is the sole market-maker, the broker-dealer must disclose this fact and the
broker-dealer's presumed control over the market. Finally, monthly statements
must be sent disclosing recent price information for the penny stock held in the
account and information on the limited market in penny stocks. Consequently, the
"penny stock" rules may restrict the ability of broker-dealers to sell the
common stock and accordingly the market for our common stock.

events described in these risk factors and elsewhere in this prospectus could



                                       11


have a material adverse effect on our business, results of operations, financial
position and the price of our common stock.

                                   THE COMPANY

      Our business has two segments, the Laser and Photonics Group and the
Plastics Group. We sell products and services in the fields of material
processing, advanced manufacturing methods, high productivity production mold
building and laser-application technology. Our Laser and Photonics Group
provides comprehensive laser-based materials and processing services. Our
Plastics Group provides rapid prototyping services and proprietary mold building
services.

The Laser and Photonics Group

      We are a leading provider of applied photonics. Specifically, we provide
high value, laser-based manufacturing services to industrial customers. We use
laser driven technologies that enable cost effective component fabrication for
customers in the aerospace, defense, medical, telecommunications and sensing
industries. Through industry and government funded research, we have developed
proprietary manufacturing techniques that, we believe, have established us as a
valued supplier of engineered components. These skill sets range from classical
laser materials processing to state of the art injection molding tooling
technology.

      Photonics is the science of generating and harnessing light to do useful
work. Lasers and fiber optics are the best known expressions of photonics
technology. According to Lucent Technologies' Vision Statement: "Optical
technology will be as important to the 21st Century as electricity was to the
20th Century."

      Photonic technologies use light to:

      o     deposit materials;
      o     detect, transmit, store and process information;
      o     generate energy; and
      o     capture and display images.

      The basic unit of light is the photon, while in electronics it is the
electron. Because photons are massless and travel faster than electrons,
photonic devices can be smaller and significantly faster than electronic
devices. For example, replacing electronics (copper wire) with photonics (fiber
optic cable) boosts the capacity of telecommunications transmission lines by a
factor of 10,000.

      Photonic components are the "enabling technology" in many familiar
consumer products including CD-ROM players, digital cameras, displays on laptop
computers and calculators, fiber optic cable for telephones, cable television,
and networked computer systems. In industry, photonics "eyes" enable robots to
"see." Photonics is also found in semiconductor manufacturing as well as
analytical and process-monitoring applications. In medicine, photonics is at the
core of diagnostic instrumentation, laser microsurgery, and filmless real-time
imaging.

Our Evolution in Applied Photonics

      Since their invention in the early 1960's, lasers have played an
increasingly important role in manufacturing through processes including
welding, cutting, drilling, and engraving. Laser Fare, one of our subsidiaries,
was formed in 1978 to provide these services and has established itself as a
leading


                                       12


provider in that area. One of our founders was the immediate past president of
the Laser Institute of America, a not-for-profit trade group representing the
photonics industry.

      In the last several years improvements in laser performance and new
adaptations of their use have enabled the development of a number of new
manufacturing processes. These processes not only provide significant
improvements over older generation laser processes, but permit the manufacture
of products that previously could not be produced on a cost-effective basis.
Through our Laser Fare Advanced Technology Group ("ATG"), the research and
development unit within Laser Fare, we have played a key role in developing
several laser processes and, as a result, have developed a portfolio of
intellectual property rights. We are focusing our future business development
efforts and our future growth in these new areas.

Our Strategic Alliance Partners and Consortia

      As a result of our expertise in the field of applied photonics, we have
established strategic alliances with a number of private sector companies,
academic institutions and public/private consortia. For example, our expertise
in the area of direct write and grating coupled surface emitting lasers
("GCSEL") has made possible our alliances with Cutting Edge Optronics, Inc.,
Triton Systems Inc. and the University of Connecticut. We are also a member of
the LENS(R) CRADA (Laser Engineered Net Shaping -- Cooperative Research and
Development Agreement) at Sandia National Laboratories. Other members of LENS(R)
CRADA include Ford Motor, Motorola, Lockheed Martin, and others. In addition, we
serve on three DARPA MICE (Defense Advanced Research Projects Agency -Mesoscopic
Integrated Conformal Electronics) teams along with Optomec, CMS Technetronics
and the State University of New York at Stonybrook. Substantially all of our
research and development is funded by third parties. We believe this strategy
provides us with a built-in customer base and market. Generally, we retain the
rights to intellectual property developed in our fields of use.

Our Services

      We use lasers to either subtract metals from a block of metal (known as,
precision laser materials processing) or to add or deposit metals (known as
laser material deposition processing). The subtractive process uses lasers to
cut away, drill or weld metals to form a part. The additive process uses lasers
to add or build metals on to a surface. Both processes can be used for a wide
variety of commercial applications, including:

      o     Large parts ("macroscale"), such as jet engine components;

      o     Handheld parts ("mesoscale"), such as GPS (global positioning
            system) antennas and sensors;

      o     Barely visible or not visible to the human eye size parts
            ("microscale"), such as medical stents used in angioplasty, gratings
            for tunable lasers in telecommunications, and circuitry for next
            generation electronics, sensors and medical devices.

      Our services can be grouped into three major categories:

      1.    Precision Laser Materials Processing. Improved performance of lasers
            has allowed classic laser materials processing, such as cutting and
            welding, to be done at the micro-level. For example, through our
            Laser Fare and Mound Laser and Photonics Center, another of our
            subsidiaries, we believe we have superior technological capabilities
            in this area. Current applications include:


                                       13


            Micro Machining -- Both Laser Fare and Mound provide laser machining
                  on a micro scale. For example, we currently manufacture
                  medical devices, such as stents. Stents are sections of small
                  stainless steel tubing, most of which have been machined away
                  to leave a mesh which can be expanded once the surgeon has
                  inserted it into an artery. The stent is used to hold open an
                  artery once an angiogram has been performed.

            Macro Machining -- Laser Fare is a leading provider of laser
                  material processing services to the aerospace, gas turbine,
                  automotive, and medical industries.

      2.    Laser Material Deposition Processing. LENS(R) CRADA has developed a
            number of methods, many with our involvement, to deposit controlled
            amounts of a metal material on a selected surface. Our Laser Fare,
            Mound Laser and Photonics Center and Express Pattern subsidiaries
            have developed and continue to develop high value manufacturing
            services in this area. Examples of laser material deposition
            processes, or additive processes, include:

            LENS  Process -- The LENS(R) CRADA process was developed at Sandia
                  National Laboratories by a consortium of companies of which we
                  are a part. As a result, we have an irrevocable, fully-paid
                  nonexclusive, world-wide license for the technology developed
                  under this program. Laser Fare has entered into contracts for
                  macro applications relating to this process. These
                  applications include depositing metals for the overhaul and
                  repair of military and high value commercial parts, such as
                  aerospace parts. We have also begun building mesoscale parts
                  for such diverse applications as titanium golf club heads and
                  titanium spinal medical devices. Micro applications include
                  small fractal antenna fabricated using silver alloys for
                  handheld GPS (global positioning systems), and other wireless
                  applications.

                  Furthermore, the design, manufacture and marketing of wireless
                  devices is standardized under industry conventions, known as
                  the Bluetooth conventions, in a manner similar to those set
                  for traditional telecommunications applications under the
                  Bellcore standards. We expect to be able to deploy laser
                  direct write technologies to address wireless components.

            PulsedLaser Deposition -- This is a proprietary process developed
                  by Mound Laser and Photonics Center to bond one metal to a
                  different metal using lasers. For example, we can bond very
                  thin layers of titanium to other metals for high temperature
                  superconductors (HTS) used in satellite electronics and other
                  applications.

            Rapid Prototyping -- Express Pattern and ATG use a variety of
                  additive techniques to provide rapid prototyping services to
                  industrial customers. These services enable customers to
                  reduce risk in product development by providing fast, low cost
                  prototypes that allow designs to be tested before large
                  investments in tooling are made.

      3.    Laser-related Contract Research and Development. We continue
            research and development in both additive and subtractive laser
            material processes, as well as GCSEL and diode lasers. We are both a
            prime contractor and subcontractor to several projects sponsored by
            DARPA. We are subcontractors on three of DARPA's MICE programs.


                                       14


            Other projects include acoustic bandgap research for the U.S. Naval
            Underwater Warfare Center ("NUWC") and Electric Boat, as well as
            photonic bandgap and high temperature superconductor ("HTS")
            research for the U.S. Air Force Research Laboratory ("AFRL"). We
            also have an agreement with the National Center for Manufacturing
            Sciences to provide higher quality metal part repairs at a lower
            cost than traditional methods under NCMS's Commercial Technologies
            for Maintenance Activities Program. This program enables the
            cost-effective repair of parts that previously would have been
            discarded at significant cost to military and commercial users. NCMS
            is a not-for-profit cooperative research consortium and is funded by
            the Department of Defense as well as over 175 corporations in the
            United States and Canada.

            We are also working with researchers at the Photonics Research
            Center at the University of Connecticut and at the Ioffe Institute
            in St. Petersburg, Russia on grating coupled surface emitting
            lasers. The AFRL funds this work.

      We intend to continue to use a combination of direct sales to customers,
contract research and development for new and existing customer applications and
early stage prototype assistance to foster our growth and satisfy specific
customer requirements. We will continue to provide these customers with
traditional and advanced manufacturing services to fabricate their components in
the most cost-effective manner.

The Plastics Group

      Our Plastics Group provides rapid prototyping services through our Express
Pattern subsidiary, and builds both conventional precision molds and our
proprietary Express Tool molds at our Osley & Whitney subsidiary. We believe the
Express Tool process provides superior thermal management properties over
conventional tooling. Better thermal management allows parts to be ejected from
the molds more quickly than by conventional means, which reduces part distortion
and the cost per part. The process resulted from a research contract in advanced
manufacturing methods at our Laser Fare ATG research facility conducted for
Hasbro. Hasbro retains the rights to the process for the toy and game industry.
We have the intellectual property rights in other fields of use. Once in

Recent Developments --Equity Line of Credit

      On November 20, 2000 we entered into an equity line of credit agreement
with Cockfield Holdings Limited. The purpose of the equity line of credit is to
provide us with a source of funding for our current activities and for the
development of our current and planned products. The equity line of credit
agreement establishes what is sometimes referred to as an equity drawdown
facility.


      Under the equity line of credit agreement, Cockfield has agreed to
purchase up to 3,000,000 shares of our common stock during the 36-month period
beginning February 9, 2001. During this 36-month period, we may request a
drawdown under the equity line of credit by selling shares of our common stock
to Cockfield. The minimum amount we can request a draw down of at any one time
is $200,000. The maximum amount we can request a draw down of at any one time is
$5,000,000. The actual amount purchased may be less than the minimum and/or
maximum amounts and will be determined at the time of the drawdown request under
a formula. We may request a drawdown once every 20 trading days, although we are
under no obligation to request any drawdowns.



                                       15


      In order to exercise our drawdown rights under the equity line of credit
agreement, we must have an effective registration statement on file with the
Securities and Exchange Commission registering the resale of the shares of our
common stock that may be sold to Cockfield under the equity line of credit
agreement. We must also give at least 20 business days advance notice to
Cockfield of the date on which we intend to exercise a particular put right and
we must indicate the maximum number of shares of our common stock that we intend
to sell to Cockfield. At our option, we may also designate a maximum dollar
amount of our common stock that we will sell under the put and/or a minimum
purchase price per share at which Cockfield may purchase shares under the put.
The maximum amount may not to exceed the lesser of a) $5,000,000 or b) fifteen
percent (15%) of the weighted average price of our common stock during the 20
trading days immediately prior to the put date, multiplied by the total trading
volume of our common stock during the 20 trading days immediately prior to that
date.

      During the 20 trading days following a drawdown request, we will calculate
the number of shares we will sell to Cockfield and the price per share. The
purchase price per share of common stock will be at a discount to the daily
volume weighted average price of our common stock during the 20 trading days
immediately following the drawdown date. On each of the 20 trading days during
the calculation period, the number of shares to be purchased by Cockfield will
be determined by dividing 1/20th of the drawdown amount by the purchase price on
each trading day. If we designate a minimum purchase price in our drawdown
request and the daily volume weighted average price for our common stock on any
trading day during the 20 trading day calculation period is below the minimum
threshold price, and Cockfield elects not to purchase shares at the minimum
threshold price, then the drawdown amount will be reduced by 1/20th.

      For each share of our common stock, Cockfield will pay us 87.5% of the
volume weighted market price for a share of our common stock during the 20-day
trading period following the exercise of a put. The percentage will increase to
90% if we move our principal market to the Nasdaq National Market or to 91% if
we move our principal market to the New York Stock Exchange. It will decrease to
84% if our common stock is delisted from the Nasdaq SmallCap Market. Market
price is defined as the volume weighted average price for our common stock (as
reported by Bloomberg Financial LP using its VAP function) on its principal
market during the pricing period. The pricing period is defined as the 20 day
trading period immediately prior to the day we exercise our put right.

      Cockfield will pay for the shares on the 22nd trading day following the
drawdown request. We will receive the purchase price less a brokerage fee
payable to Jesup & Lamont ranging between 4.25% and 4.75% of the aggregate
purchase price, depending on the dollar volume of the transaction. Jesup &
Lamont is the placement agent that introduced Cockfield to us and is a
registered broker-dealer.

      At the closing of each drawdown, we will also grant Cockfield warrants to
purchase a number of shares of our common stock equal to 33% of the number of
shares purchased by Cockfield at the closing of the drawdown. These unit
warrants will expire one day after they are granted and will have an exercise
price equal to the weighted average of the purchase price of a share of our
common stock purchased at the closing of each drawdown. The 3,000,000 shares of
common stock available under the equity line of credit will be reduced by the
number of shares issued as a result of the exercise of these unit warrants.

      The equity line of credit agreement prevents us from drawing down funds
and issuing the corresponding shares of common stock to Cockfield if the
issuance would result in Cockfield beneficially owning more than 9.9% of our
then outstanding shares of common stock. In addition, the listing requirements
of the Nasdaq SmallCap Market prohibit us from issuing 20% or more of our issued
and outstanding shares of common stock in a single transaction at a price less
than the greater of market value or book value unless we get stockholder
approval. Accordingly, we intend to seek stockholder approval to issue the
shares of our common stock contemplated by the equity line of credit agreement.


                                       16


      As consideration for establishing the equity line of credit, we granted
Cockfield warrants to purchase up to 200,000 shares of our common stock. As
consideration for the services rendered by Jesup & Lamont as placement agent in
connection with the equity line of credit, we granted Jesup & Lamont warrants to
purchase up to 100,000 shares of our common stock. These warrants, covering
300,000 shares of our common stock, are exercisable at any time prior to
November 20, 2003, for $3.135 per share. If the 300,000 warrants are exercised
in full, we would receive gross proceeds of $940,500. Neither Cockfield nor
Jesup & Lamont are obligated to exercise these warrants.


      The 3,000,000 shares of our common stock issuable to Cockfield under the
equity line of credit agreement and the 300,000 shares of our common stock
underlying the warrants that were granted to Cockfield and Jesup & Lamont are
covered by a registration statement filed under the Securities Act of 1933 and
may be offered for sale from time to time during the period the registration
statement remains effective. The number of shares covered by that registration
statement represents 95% of our issued and outstanding common stock as of April
1, 2001. We are obligated to prepare and file amendments and supplements to that
registration statement as are necessary to maintain its effectiveness until all
of those shares are sold or until they can be sold under an appropriate
exemption from registration, whichever is earlier. We agreed to bear the
expenses of registering those shares, including our legal fees, but not the
expenses associated with selling the shares, such as broker discounts and
commissions.

                                 USE OF PROCEEDS


      All of the shares of our common stock offered by this prospectus are being
registered for the account of the selling stockholders. We will not receive any
of the proceeds from the sale of these shares. However, we will receive the
proceeds from the exercise of the warrants covering the 154,300 shares of common
stock covered by this prospectus to the extent those warrants are exercised and
from the exercise of 65,000 options to the extent those options are exercised.
These proceeds would be approximately $395,700 if all the warrants and options
are exercised. In addition, this prospectus also covers 31,250 shares of common
stock that a selling stockholder is obligated to purchase from us on May 26,
2001 for $62,500. We expect to use substantially all the net proceeds from the
exercise of the warrants and the sale of the shares for general corporate
purposes, including research and development, expansion of sales and marketing
activities and working capital. We will retain broad discretion in the
allocation of those net proceeds.

(1)   Beneficial ownership is determined in accordance with the rules of the
      Securities and Exchange Commission. In computing the number of shares
      beneficially owned by a person and the percentage ownership of that
      person, shares of common stock underlying options and warrants held by
      that person that are currently exercisable or exercisable within 60 days
      of April 15, 2001 are deemed outstanding. These shares, however, are not
      deemed outstanding for the purpose of computing the percentage ownership
      of any other person.


(2)   Includes 50,000 shares subject to currently exercisable warrants
      (exercisable at $1.625 per share through May 31, 2005) and 31,250 shares
      issuable on May 26, 2001 pursuant to a subscription agreement. The
      purchase price for those shares is $2 per share, or $62,500 in the
      aggregate.

                              PLAN OF DISTRIBUTION

      The selling stockholders and any of their pledgees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares
of common stock covered by this prospectus on any stock exchange, market or
trading facility on which the shares are traded or in private transactions.
These sales may be at fixed or negotiated prices. The selling stockholders may
use any one or more of the following methods when selling shares:

      o     ordinary brokerage transactions and transactions in which the
            broker-dealer solicits purchasers;

      o     block trades in which the broker-dealer will attempt to sell the
            shares as agent but may position and resell a portion of the block
            as principal to facilitate the transaction;

      o     purchases by a broker-dealer as principal and resale by the
            broker-dealer for its account;

      o     an exchange distribution in accordance with the rules of the
            applicable exchange;

      o     privately negotiated transactions;

      o     short sales;

      o     broker-dealers may agree with the selling stockholders to sell a
            specified number of such shares at a stipulated price per share;

      o     a combination of any such methods of sale; and

      o     any other method permitted pursuant to applicable law.

      The selling stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

      The selling stockholders may also engage in short sales against the box,
puts and calls and other transactions in our securities or derivatives of our
securities and may sell or deliver shares in connection with these trades. The
selling stockholders may pledge their shares to their brokers under the margin
provisions of customer agreements. If a selling stockholder defaults on a margin
loan, the broker may, from time to time, offer and sell the pledged shares.

      Broker-dealers engaged by the selling stockholders may arrange for other
brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the selling stockholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated. The selling stockholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved.

      The selling stockholders and any broker-dealers or agents that are
involved in selling the shares may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales. In such event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act.


                                       21



      We will pay all of the expenses relating to the registration of the shares
covered by this prospectus except for selling commissions. These expenses are
estimated at $30,000.00.


                                 LEGAL MATTERS

      The validity of the common stock offered hereby will be passed upon by
Morse, Zelnick, Rose & Lander, LLP. Members of Morse, Zelnick, Rose & Lander,
LLP own options to purchase 65,000 shares of our common stock.

Item 15. Indemnification of Officers and Directors

      Our Certificate of Incorporation provides that the indemnification
provisions of Sections 102(b)(7) and 145 of the Delaware General Corporation Law
shall be utilized to the fullest extent possible. Further, the Certificate of
Incorporation contains provisions to eliminate the liability of our directors to
Infinite or its stockholders to the fullest extent permitted by Section
102(b)(7) of the Delaware General Corporation Law, as amended from time to time.

      Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify directors and officers as well as other employees and
individuals against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with any threatened, pending or completed actions, suits or
proceedings in which such person is made a party by reason of such person being
or having been a director, officer, employee or agent of the corporation. The
Delaware General Corporation Law provides that Section 145 is not exclusive of
other rights to which those seeking indemnification may be entitled under any
bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

      Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (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) for
unlawful payments of dividends or unlawful stock repurchases, redemptions or
other distributions, or (iv) for any transaction from which the director derived
an improper personal benefit. Our Certificate of Incorporation provides for such
limitation of liability.

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended, is permitted for our directors, officers or controlling
persons, pursuant to the above mentioned statutes or otherwise, we understand
that the Securities and Exchange Commission is of the opinion that such
indemnification may contravene federal public policy, as expressed in said Act,
and therefore, may be unenforceable. Accordingly, in the event that a claim for
such indemnification is asserted by any of our


                                      II-1


directors, officers or controlling persons, and the Commission is still of the
same opinion, we (except insofar as such claim seeks reimbursement from us of
expenses paid or incurred by a director, officer of controlling person in
successful defense of any action, suit or proceeding) will, unless the matter
has theretofore been adjudicated by precedent deemed by our counsel to be
controlling, submit to a court of appropriate jurisdiction the question whether
or not indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.

      At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees as to which indemnification is sought, nor
are we aware of any threatened litigation or proceeding that may result in
claims for indemnification.

Item 17. Undertakings

      The undersigned registrant hereby undertakes:

      (1)   to file, during any period in which offers or sales are being made,
            a post-effective amendment to this registration statement:

            (i)   to include any prospectus required by Section 10(a)(3) of the
                  Securities Act of 1933;


            (ii)  to reflect in the prospectus any facts or events arising after
                  the effective date of the registration statement (or the most
                  recent post-effective amendment thereof) which, individually
                  or in the aggregate, represent a fundamental change in the
                  information set forth in the registration statement.
                  Notwithstanding the foregoing, any increase or decrease in
                  volume of securities offered (if the total dollar value of
                  securities offered would not exceed that which was registered)
                  and any deviation from the low or high end of the estimated
                  maximum offering range may be reflected in the form of
                  prospectus filed with the Commission pursuant to Rule 424(b)
                  if, in the aggregate, the changes in volume and price
                  represent no more than 20% change in the maximum aggregate
                  offering price set forth in the "Calculation of Registration
                  Fee" table in the effective registration statement; and


            (iii) to include any material information with respect to the plan
                  of distribution not previously disclosed in the registration
                  statement or any material change to such information in the
                  registration statement;


                                      II-3


provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply
if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934, that are incorporated by reference in this
Registration Statement.

            (2)   that, for the purpose of determining any liability under the
                  Securities Act of 1933, each such post-effective amendment
                  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; and

            (3)   to remove from registration by means of a post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of this offering.

      (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in this Registration Statement 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.

      (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 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 of 1933 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 of 1933 and will be governed by the final adjudication of such
issue.


                                      II-4


                                   SIGNATURES


      Pursuant to the requirements of the Securities Act of 1933, as amended,
the registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-3 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Warwick, State of Rhode Island and Providence
Plantations on this 3rd day of May, 2001.
