                         UNIVERSAL DISPLAY CORPORATION

   This is a summary of information appearing elsewhere in this prospectus.
This summary does not contain all of the information you should consider
before investing in our common stock. This summary is qualified in its
entirety by, and should be read in conjunction with, the more detailed
information and financial statements, including the notes to the financial
statements, appearing elsewhere in this prospectus or in our annual and
quarterly reports and other filings with the Securities and Exchange
Commission. References in this prospectus to "we," "us," "Company" and "our"
refer to Universal Display Corporation, together with its wholly-owned
subsidiary, UDC, Inc.

Our Company

   Universal Display Corporation is engaged in the research, development and
commercialization of organic light emitting diode, or OLED, technology for use
in flat panel displays, lasers and light generating devices. We expect the
initial market for our technology to be in the electronic flat panel display
industry. This industry includes such products as:

   o cellular phone displays;

   o portable personal digital assistants and Internet access-type devices;

   o laptop computers; and

   o television and computer monitors.

   Stanford Resources, Inc. estimated the size of the electronic display market
to be approximately $41 billion in 2000. The flat panel part of this market is
approximately $17 billion in 2000.

   We have the exclusive, perpetual, worldwide license to commercialize all
OLED technology, intellectual property and know-how developed by Princeton
University and the University of Southern California, subject to the terms of
our Sponsored Research Agreement and License Agreement with those
universities. To date, 34 patents have been issued in the United States.
Approximately 40 patent applications (with corresponding foreign protection)
have been filed, and additional patents are being filed monthly. We have also
obtained a license, with rights to sublicense, to 70 US patents, approximately
4 US patent applications, and additional foreign patents related to OLED
technology owned by Motorola, Inc.

Our OLED Technology

   Organic light emitting diodes are made of material containing a carbon-based
substance that has the capability to emit light when electric current is
passed through it. We, in collaboration with our research and development
partners, are working towards commercializing innovative OLED technology,
including the following six proprietary OLED technology platforms

   o TOLED Technology: Our transparent OLED can be used to create transparent
     displays for information displays on windshields, cockpit displays on
     aircraft and head mounted displays. TOLEDs can also be used in numerous
     portable electronic applications because of their bright colors, high
     contrast, low power requirements and top emission characteristics.

   o SOLED Technology: Unlike traditional side-by-side display architecture,
     which places the red, green and blue picture elements, or pixels,
     horizontally next to each other, our stacked OLED stacks the red, green
     and blue pixels vertically on top of each other. Thus, to display green
     in the conventional architecture, you turn off the red and blue pixels,
     leaving spaces between each of the illuminated green pixels. In SOLED, to
     display green, you turn off the red and blue sections of the stacked
     pixel component. The stacked architecture of the SOLED may increase the
     resolution of the display by a factor of three.

   o FOLED Technology: Unlike conventional displays, our flexible OLEDs can be
     built on flexible materials such as plastic. We believe that such
     displays will be lighter in weight and

                                       2


     will have lower power requirements. The FOLED also may provide the
     opportunity to apply low cost roll to roll (web processing) technologies
     to display fabrication, which can reduce the cost, and therefore expand
     the market, of electronic flat panel displays.

   o Organic Laser Technology: We and our research partners are attempting to
     develop a fourth technology platform based upon the ability to fabricate
     an organic laser utilizing OLED technology. In the September 25, 1997
     issue of Nature, our research partners announced what they believed to be
     the first evidence of lasing from vacuum deposited thin films of organic
     molecules. We believe this is a significant first step towards the
     realization of electrically pumped, solid-state lasers based on organic
     thin films.

   o High Efficiency Materials: A fifth technology platform respects the use
     of molecules that emit light through the process of phosphorescence. This
     class of molecules has the potential for higher efficiency, lower power
     and longer lifetimes than conventional OLED technology which involves the
     emission of light through the process of fluorescence. We and our
     research partners first announced this discovery in the September 10,1999
     issue of the scientific journal, Nature.

   o Organic Vapor Phase Deposition: A sixth technology platform involves the
     use of a carrier gas stream in a hot walled reactor at low vacuum to
     precisely deposit the thin layers of organic materials used in OLED
     displays. Conventional OLED fabrication equipment evaporates the organic
     molecules at high vacuum. We have entered into a Development and License
     Agreement with Aixtron AG, a German company that manufactures precision
     semiconductor production equipment for LED's, to further develop,
     commercialize and produce manufacturing equipment for OLEDs based on this
     technology.

Our Research Partners

   Princeton and USC have been performing research on OLED technology for many
years, and have continued that research for us since 1994. The sponsored
research agreement between us and our research partners, which was originally
executed in 1994, was extended in 1997 for five additional years and is
subject to further extension by mutual agreement.

   Key members of our research team include Dr. Stephen Forrest at Princeton
and Dr. Mark R. Thomson at USC. There are approximately 20 researchers at
Princeton and USC who are engaged in OLED research.

Our Commercialization Strategy

   Our approach to developing technology and penetrating the electronic display
market has four major components:

o    We are continuing to fund our research partners under the current
     sponsored research agreement and to obtain the worldwide exclusive rights
     to all intellectual property invented in the project.

o    We are working on the development of reliable commercial prototypes and
     the optimization of the fabrication processes. In 1999, we moved into an
     11,000 square foot space near Princeton, New Jersey to serve as a pilot
     line facility and technology transfer center.

o    We have entered into Agreements with an Equipment manufacturer, Aixtron
     AG; and an organic materials developer and supplier, PPG Industries,
     Inc., to further develop and commercialize our technology, and
     potentially obtain royalties from the sales of certain equipment and
     revenues from the sales of certain materials to OLED manufacturers.

o    We intend to license our proprietary OLED technology and enter into joint
     ventures and other strategic alliances with experienced manufacturers and
     users of display products for the volume manufacture, distribution and
     sale of products based upon this technology. We do not presently intend
     to become a volume manufacturer.

                                       3


Our Development Partners

   We have entered into agreements with three companies:

o    Effective October 1, 2000, the Company entered into a Development and
     License Agreement with PPG Industries, Inc. (PPG) to leverage our OLED
     flat panel display technology with PPG's expertise in organic materials
     development and manufacturing. A team of PPG scientists and engineers
     will assist us in developing and commercializing our proprietary OLED
     system. Present staffing levels will provide the full time services of 7
     PPG employees, plus managerial services. Based upon current staffing
     levels, we anticipate issuing to PPG approximately 114,000 shares of
     common stock annually for the period from January 1, 2001 through
     December 31, 2005, of which 227,766 shares are being offered hereunder.
     In addition, we anticipate issuing to PPG annually warrants to purchase
     up to an additional 114,000 shares of our common stock over the period
     from January 1, 2001 through December 31, 2005, of which warrants to
     purchase 113,883 shares of our common stock are being offered hereunder.
     The amount of equity to be obtained by PPG under the agreement is subject
     to adjustment under certain circumstances. PPG's services have an
     estimated value of approximately $11 million. PPG also has the right to
     request that we grant royalty bearing licenses to PPG for use of our OLED
     technology in certain applications. This agreement was amended effective
     March 7, 2001.

     We also entered into a Supply Agreement with PPG whereby PPG will be the
     exclusive supplier of our proprietary materials through December 31,
     2007. PPG will sell the materials to us, and we will resell them to OLED
     manufacturers.

o    Effective September 29, 2000, we entered into a License Agreement with
     Motorola, Inc., whereby we obtained the rights, with the right to
     sublicense, to 70 US patents, 4 pending US patents, and certain foreign
     patents of Motorola, Inc., related to OLEDs. Our agreement with Motorola
     also includes the opportunity to meet with their product development
     group, although there are no assurances that Motorola will purchase any
     products from the Company or its licensees, or use any of the Company's
     technology in their products. In connection with the rights granted to
     the Company under the agreement, we issued to Motorola 200,000 shares of
     common stock, 300,000 shares of Convertible Preferred Stock (each share
     convertible into one share of common stock, subject to adjustment under
     certain circumstances, and vesting 75,000 shares per year), and Warrants
     to purchase an additional 150,000 shares.

o    Effective July 19, 2000, we entered into a Development and License
     Agreement with Aixtron AG of Germany to further develop and commercialize
     manufacturing equipment for OLEDs based on a proprietary UDC technology
     called Organic Vapor Phase Deposition (OVPD). Aixtron AG is a world
     leader in the production of manufacturing equipment for LED's using MOCVD
     (Metal-organic chemical vapor deposition) technology. Under the
     agreement, UDC and Aixtron will engage in a joint development program to
     commercialize OVPD equipment. Aixtron has the exclusive license to
     produce equipment based on this technology, and UDC will receive a
     royalty from the sale of the equipment.

                                  RISK FACTORS

   An investment in our common stock involves a high degree of risk. In
addition to the other information contained in this prospectus, you should
carefully consider the following risk factors before making an investment
decision concerning our common stock. You should not purchase our common stock
if you cannot afford the loss of your entire investment.

We do not expect to be profitable in the foreseeable future, and may never be
profitable.

   Since inception, we have not generated any product revenues, and have
incurred significant losses, resulting in an accumulated deficit of
approximately $28.2 million, as of December 31, 2000. We expect to incur
losses for the foreseeable future and until such time, if ever, as we are able
to achieve sufficient levels of revenue from the commercial exploitation of
the OLED technology to support our operations. You should note, however, that:

   o OLED technology may never become commercially viable;

   o markets for flat panel displays utilizing the OLED technology may be
     limited; and

   o we may never generate sufficient revenues from the commercial
     exploitation of the OLED technology to become profitable.

   Additionally, even if we find commercially viable applications for our OLED
technology, we may never recover our research and development costs.

If we do not receive additional financing in the future, we will not be able
continue the research, development and commercialization of our OLED
technology.

   Our capital requirements have been and will continue to be significant. The
completion of the research, development and commercialization of the OLED
technology for potential applications will require significant additional
effort and resources. Our cash on hand is not sufficient to meet all of our
future obligations. When we need additional funds, such funds may not be
available on commercially reasonable terms or at all. If we cannot obtain more
money when we need it, our business might fail. Additionally, if we attempt to
raise money in an offering of our common stock, the issuance of additional
stock will dilute our then existing shareholders.

If our OLED technology is not feasible for product applications, we may never
generate significant revenues.

   At this time, we are unable to determine the feasibility of our OLED
technology for the commercial viability of any potential applications. Before
products utilizing the OLED technology are manufactured and sold, we must make
substantial advances in our research and development efforts in a number of
areas, including:

   o reliability;

   o the development of more fully saturated colors for full color displays;

   o integration with drive electronics; and

   o issues related to scalability and cost effective fabrication technologies
     for product applications.

   The development of an electrically pumped laser is also necessary before
products based on the organic laser research are manufactured and sold. Our
efforts may never demonstrate the feasibility of our OLED technology,
particularly for use in full color, large area, high resolution, high
information content flat panel display applications.

   Our research and development efforts remain subject to all of the risks
associated with the development of new products based on emerging and
innovative technologies, including, without limitation, unanticipated
technical or other problems and the possible insufficiency of the funds
allocated to complete its development. Technical problems may result in delays
and cause us to incur additional expenses that would increase our losses. If
we cannot complete our research and development of the OLED technology
successfully, or if we

                                       5


experience delays in completing our research and development of the OLED
technology for use in potential applications, particularly after the
occurrence of significant expenditures, our business may fail.

Even if our technology is technically feasible, it may not be accepted by the
market.

   The potential size, timing and viability of market opportunities targeted by
us are uncertain at this time. Market acceptance of the OLED technology will
depend, in part, upon such technology providing benefits comparable to CRT and
LCD technology (the current standard for display quality) at an appropriate
cost, and its adoption by consumers, neither of which have been achieved. Many
potential licensees of the OLED technology manufacture flat panel displays
utilizing competing technologies and may, therefore, be reluctant to redesign
their products or manufacturing processes to incorporate the OLED technology.
Potential licensees may never utilize the commercially viable OLED technology.

If our research partners fail to make advances in their research, or if they
terminate their relationship with us, we might not succeed in commercializing
our OLED technology.

   Research and development of commercially viable applications for OLED
technology is dependent on the success of the research efforts of our research
partners conducted under our sponsored research agreement with them. We cannot
assure you that our research partners will make additional advances in the
research and development of the OLED technology.

   Although we fund the OLED technology research, the scope of and technical
aspects of the research as well as the resources and efforts directed to such
research is subject to the control of our research partners. Our sponsored
research agreement provides that if Dr. Forrest is unavailable to continue to
serve as a principal investigator, either because he is no longer associated
with Princeton or otherwise, and a successor acceptable to both us and
Princeton is not available, Princeton has the right to terminate the sponsored
research agreement. The 1997 sponsored research agreement, which expires in
July 2002, may not be extended. The termination or expiration of the sponsored
research agreement or the 1997 license agreement would materially and
adversely affect our ability to research, develop and commercialize our OLED
technology.

If we cannot form strategic relationships with companies that manufacture and
use products that incorporate our OLED technology, our commercialization
strategy will fail.

   Our strategic plan depends upon the development of strategic relationships
with companies that will manufacture and use products incorporating its OLED
technology. We have not yet entered into any such strategic relationships,
although we have entered into a Development and Licensing Agreement with
Aixtron AG to develop and commercialize a new type of production equipment for
OLEDs based upon our proprietary technology. Our agreement with Motorola also
includes the opportunity to meet with their product development group,
although there are no assurances that Motorola will purchase any products from
UDC or its licensees. Our agreements with PPG provide us with the capability
to sell chemicals to our licensees. In December, 1999, we moved into a new
facility which includes a prototype pilot line and technology transfer
facility to accelerate the development and commercialization of our
technology. We cannot assure you that such a facility will allow us to enter
into such strategic relationships.

   Our prospects will be significantly affected by our ability to sublicense
the OLED technology and successfully develop strategic alliances with third
parties for incorporation of the OLED technology into flat panel displays
manufactured by others. Strategic alliances may require financial or other
commitments by us. We might not be able, for financial or other reasons, to
enter into strategic alliances on commercially acceptable terms, or at all.
Failure to do so would have a material adverse effect on us.

If we cannot protect our intellectual property rights, or if our technology
infringes the rights of others, our business will suffer.

   Our rights to the OLED technology are dependent on patents and other
intellectual property rights relating to the OLED technology that are licensed
to us by Princeton and USC. Thirty-four U.S. patents have already been issued,
approximately 40 additional patent applications are pending in the United
States and corresponding international patent applications have been filed to
cover the major industrial countries. However, there can be no assurance that
additional patents applied for will be obtained or that any such

                                       6


patents will afford us commercially significant protection of our OLED
technology, or will be found valid if challenged. In connection with our
license agreement with Motorola, Inc., we have obtained a license to 70
additional OLED-related U.S. patents, 4 patent applications, related foreign
patents and applications, and the right to sublicense this technology.

   The patent laws of other countries may differ from those of the United
States as to the patentability of the OLED technology and the degree of
protection afforded. Older companies and institutions may independently
develop equivalent or superior technologies and may obtain patent or similar
rights with respect thereto. There are a number of other companies and
organizations that have been issued patents and are filing additional patent
applications relating to OLED technology, including Eastman Kodak Corporation,
which holds a number of patents related to OLED technology. There can be no
assurance that the exercise of some aspects of our licensing rights respecting
its OLED technology being developed by Princeton and USC or those licensed
from Motorola, Inc. will not infringe on the patents of others, in which event
we or our research partners may be required to obtain a license, pay damages,
modify their products or method of operation or be prohibited from making,
using, selling or offering to sell some or all products incorporating our OLED
technology. We also might not have the financial or other resources necessary
to enforce or defend a patent infringement action, and the licensors of our
licensed technology might not enforce an action in a timely manner. If
products incorporating our OLED technology are found to infringe upon the
patent or other intellectual property rights of others, it could have a
material adverse effect on us.

The federal government has rights to our OLED technology that might prevent us
from realizing its benefits.

   The United States government, through the Defense Advanced Research Projects
Agency, has provided funding to Princeton and us for research activities
related to certain aspects of its OLED technology. The federal government
could obtain rights to this technology, which would affect our rights as
follows:

   o If all or certain aspects of the OLED technology develop from our funding
     to Princeton, and those aspects are deemed to fall within the planned and
     committed activities of DARPA's funding, the federal government, pursuant
     to federal law, could have certain rights relating to the OLED
     technology.

   o If the federal government determines that we have not taken effective
     steps to achieve practical application of such technology in a field of
     use in a reasonable time, it may require us to grant licenses to other
     parties in any such field of use.

   o The federal government could restrict our ability to market the OLED
     technology to the federal government for military and other applications.

   o The federal government's continued funding of ours and Princeton's
     research activities may also give it rights to aspects of the OLED
     technology developed in the future.

   If so, we might not realize the benefits of that technology.

Because many of our competitors have better name-recognition, and greater
financial, technical, marketing and research capabilities than us, we may
never be able to compete successfully in the flat panel display industry.

   The flat panel display industry is characterized by intense competition. The
market is currently, and will likely continue to be, dominated by products
utilizing LCD technology. Numerous companies are making substantial
investments in, and conducting research to improve characteristics of, LCD
technology. Several other flat panel display technologies have been, or are
being, developed, including field emission, inorganic electroluminescence,
polymeric light emitting diode, gas plasma and vacuum fluorescent displays. In
addition, other companies are engaged in research and development activities
with respect to technology using OLEDs. Advances in LCD technology or any of
these developing technologies may overcome their limitations or become the
leading technology for flat panel displays, either of which could limit the
potential market for flat panel displays utilizing the Company's OLED
technology.

                                       7


   Substantially all of these competitors have better name recognition and
greater financial, technical, marketing, personnel and research capabilities
than us. Our competitors may succeed in developing technologies and
applications that are more cost-effective or have fewer display limitations
than our OLED technology. We may never be able to compete successfully or
develop commercial applications for our OLED technology.

If we cannot keep our key employees or hire other talented persons as we grow,
our business might not succeed.

   Our performance is substantially dependent on the continued services of
senior management and other key personnel, and its ability to offer
competitive salaries and benefits to its employees. We do not have employment
agreements with any of our management or key personnel. Additionally,
competition for highly skilled technical, managerial and other personnel is
intense. We might not be able to attract, hire, train, retain and motivate the
highly skilled managers and employees we need to be successful. If we fail to
attract and retain the necessary technical and managerial personnel, we will
suffer and might fail.

We can issue shares of preferred stock that can adversely affect your rights
as a shareholder.

   Our articles of incorporation authorize us to issue up to 5,000,000 shares
of preferred stock with designations, rights and preferences determined from
time-to-time by our board of directors. Accordingly, our board is empowered,
without shareholder approval, to issue preferred stock with dividend,
liquidation, conversion, voting or other rights superior to those of our
common shareholders. For example, an issuance of shares of preferred stock
could:

   o adversely affect the voting power of the common shareholders;

   o make it more difficult for a third party to gain control of us;

   o discourage bids for our common stock at a premium; or

   o otherwise adversely affect the market price of the common stock.

   Our board has designated and issued (a) 200,000 shares of Series A Preferred
Stock, all of which are held by an entity controlled by Sherwin Seligsohn and
(b) 300,000 shares of Series B Convertible Preferred Stock, which shares are
convertible into shares of our common stock in accordance with our articles of
incorporation. We may issue additional shares of our authorized preferred
stock at any time in the future.

The market price of our common stock might be highly volatile.

   The market price of our common stock might be highly volatile, as has been
the case with the securities of other emerging growth companies. Factors such
as:

   o our operating results;

   o announcements by us or our competitors of technological developments, new
     product applications or license arrangements; and

   o other factors affecting the flat panel display industry generally may
     have a significant impact on the market price of our common stock.

In recent years, the stock market has experienced a high level of price and
volume volatility and market prices for the stock of many companies,
particularly small and emerging-growth companies.

If our shares are delisted, you might not be able to sell your investment in
our company.

   Our common stock is listed on the Nasdaq National Market System. To continue
to be listed on that market, however, we must maintain, with certain
exceptions, maintenance criteria, including:

   o specified levels for total assets;

   o market value of the public float;

   o total capital and surplus; and

   o a minimum bid price per share.

                                       8


The failure to meet such maintenance criteria in the future may result in the
delisting of our common stock from the Nasdaq National Market System.
Thereafter, trading, if any, in our common stock would be conducted in the
non-Nasdaq over-the-counter market. As a result of such delisting, you could
find it more difficult to dispose of, or to obtain accurate quotations as to
the market value of, our common stock.

If we are delisted, trading in our common stock may become subject to
additional regulation that could further limit the liquidity of your
investment.

   In addition, if our common stock were to become delisted from trading on
Nasdaq and the trading price of the common stock were to remain below $5.00
per share, trading in the common stock would also be subject to the
requirements of additional rules under the Exchange Act. These rules require
additional disclosure by broker-dealers in connection with any trades
involving any non-Nasdaq equity security that has a market price of less than
$5.00 per share, subject to certain exceptions. Such rules require the
delivery, prior to any so-called penny stock transaction, of a disclosure
schedule explaining the penny stock market and the risks associated with it,
and impose various sales practice requirements on broker-dealers who sell
penny stocks to persons other than established customers and accredited
investors. For these types of transactions, the broker-dealer must make a
special suitability determination for the purchaser and have received the
purchaser's written consent to the transaction prior to sale. The broker-
dealer also must disclose the commissions payable to the broker-dealer,
current bid and offer quotations for the penny stock 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. Such information must be
provided to the customer orally or in writing prior to effecting the
transaction and in writing before or with the customer confirmation. 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. The additional burdens imposed upon broker-dealers by such
requirements may discourage broker-dealers from effecting transactions in our
common stock, which could severely limit the market liquidity of your
investment.

This offering, as well as the issuance of other publicly traded shares, could
drive our stock price down.

   Following the effectiveness of our registration statement, the shares of
common stock offered by the selling shareholders will become freely salable in
the public market. Although the sale of these additional shares to the public
might increase the liquidity of our shareholders' investments, the increase in
the number of shares available for public sale could drive the price of our
common stock down, thus reducing the value of your investment and perhaps
hindering our ability to raise additional funds in the future. To the extent
other restricted shares become freely salable, whether through an effective
registration statement or under Rule 144 of the Securities Act, or we issue
additional shares that might be or become freely salable, you could expect our
stock price to decrease.

Pursuant to the terms of our agreement with PPG, we may have to issue PPG more
shares than we anticipate if our stock price goes down.

    Pursuant to the development and license agreement we entered into with PPG,
we are required to issue to PPG, for the services they expect to render to us
during a particular calendar year during the term of the agreement, shares of
common stock based on the value of such services at the beginning of the year.
If, at the time of issuance, the price of our common stock has declined
materially since the date we executed the agreement with PPG, we may be
required to issue to PPG more shares of common stock than we initially
anticipated. This increase in the number of shares available for public sale
could cause people to sell our shares, including short sales, which could
drive the price of our common stock down, thus reducing the value of your
investment and perhaps hindering our ability to raise additional funds in the
future. In addition, this increase in the number of shares outstanding would
further dilute our existing stockholders.

   Despite the possibility of the increased issuances referred to above, we
believe that no circumstances exist in which the total number of shares issued
to PPG pursuant to the development and license agreement could reasonably be
expected to exceed twenty percent (20%) of the shares outstanding at the
execution of the agreement. We reach this conclusion based on the fact that
the development and license agreement requires us to issue to PPG a number of
shares of common stock calculated by dividing the value of the

                                       9


services provided to us by PPG by the average of our stock price over a 90 day
period prior to the time the calculation is performed. However, the
development and license agreement contains a minimum price to be used in this
calculation. A decline in the market price below this minimum price would
result not in the issuance by us to PPG of additional shares of common stock,
but rather the payment to PPG of cash in an amount determined as set forth in
the development and license agreement. After considering the anticipated value
of the services to be provided by PPG, and the minimum price referred to
above, we have concluded that no circumstances exist in which the total number
of shares of common stock issued to PPG could reasonably be expected to exceed
twenty percent (20%) of the shares outstanding at the execution of the
agreement.

                                  THE OFFERING

   The selling stockholders are offering for resale up to 1,950,242 shares of
our common stock. Of the 1,950,242 shares of our common stock being offered by
the selling shareholders, 1,159,621 shares of common stock will be issued upon
the exercise of outstanding warrants.

   We originally issued the shares of common stock, and the warrants
exercisable for shares of common stock, that the selling stockholders are
offering as follows:

   In December 2000, we issued an aggregate of 790,231 units in a private
placement to investors at $8.50 per unit. Each unit consisted of one share of
common stock and one warrant to purchase one share of common stock. The
exercise price of the warrants underlying the units is 120% of the average
closing price of common stock for five trading days immediately preceding the
initial closing of the December 2000 private placement, and these warrants
have a five-year term. All of the shares of common stock that are part of the
units and shares of common stock to be issued upon the exercise of the
warrants that are still outstanding are included in this offering.

   The selling shareholders pursuant to this prospectus may sell the shares of
common stock offered for resale in a secondary offering. Under the terms of
the transactions described above, we are contractually required to register
all of the shares of common stock that are described above.

                                USE OF PROCEEDS

   The selling shareholders will receive the proceeds from the resale of the
shares of common stock. We will not receive any proceeds from the resale of
the shares of common stock by the selling shareholders.

                              SELLING SHAREHOLDERS

   The following table sets forth information regarding the beneficial
ownership of shares of common stock by the selling shareholders as of May 7,
2001, and the number of shares of common stock covered by this prospectus.
Except as otherwise noted below, none of the selling stockholders has held any
position or office, or has had any other material relationship with us or any
of our affiliates within the past three years.

   Beneficial ownership is determined in accordance with the rules of the SEC
and generally includes voting or investment power with respect to securities.
The shares of common stock subject to options or warrants currently
exercisable or exercisable within 60 days after May 7, 2001 are deemed
outstanding and to be beneficially owned by the selling shareholders holding
such options or warrants.

                              PLAN OF DISTRIBUTION

   The selling shareholders, including any donees or pledgees who receive
shares from the selling shareholders, may, from time to time, sell all or a
portion of the shares of common stock on any market upon which the common
stock my be quoted, in privately negotiated transactions or otherwise, at
fixed prices that may be changed, at market prices prevailing at the time of
sale, at prices related to such market prices or at negotiated prices. The
selling shareholders may sell the shares of common stock by one or more of the
following methods, without limitation:

   o block trades in which the broker or dealer so engaged will attempt to
     sell the shares of common stock as agent, but may partition and resell a
     portion of the block as principal to facilitate the transaction;

   o purchases by the broker or dealer as principal and resale by the broker
     or dealer for its account pursuant to this prospectus;

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

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

   o negotiated transactions or otherwise, including an underwritten offering;

   o market sales (both long and short to the extent permitted under the
     federal securities laws);

   o in connection with short sales of the shares of Common Stock;

                                       14



   o in connection with the writing of non-traded and exchange-traded call
     options, in hedge transactions and in settlement of other transactions in
     standardized or over-the-counter options, if permitted under the
     securities laws, and

   o a combination of any of these methods of sale.

   In effecting sales, brokers and dealers engaged by the selling shareholders
may arrange for other brokers or dealers to participate. Brokers or dealers
may receive commissions or discounts from the selling shareholders or, if any
such broker-dealer acts as agent for the purchaser of such shares, from such
purchaser, in amounts to be negotiated. These commissions or discounts may
exceed those customary in the types of transactions involved. Broker-dealers
may agree with the selling shareholders to sell a specified number of shares
of common stock at a stipulated price per share, and, to the extent such
broker-dealer is unable to do so acting as agent for the selling shareholders,
to purchase as principal any unsold shares of common stock at the price
required to fulfill the broker-dealer commitment to the selling shareholders.
Broker-dealers who acquire shares of common stock as principal may thereafter
resell such shares of common stock form time to time in transactions (which
may involve block transactions and sales to and through other broker-dealers,
including transactions of the nature described above) at prices and on terms
then prevailing at the time of sale, at prices then related to then-current
market price or in negotiated transactions. In connection with such resales,
broker-dealers may pay to or receive from the purchasers of shares of common
stock commissions as described above. The selling shareholders may also sell
the shares of common stock in accordance with Rule 144 under the Securities
Act of 1933 (the "Securities Act") rather than pursuant to this prospectus.

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

   From time to time, the selling shareholders may pledge their shares of
common stock pursuant to the margin provisions of their customer agreements
with their brokers. Upon default by a selling shareholders, the broker may
offer and sell such pledged shares of common stock from time to time. Upon a
sale of the shares of common stock, the selling shareholders intend to comply
with the prospectus delivery requirements under the Securities Act by
delivering a prospectus to each purchaser in the transaction. We intend to
file any amendments or other necessary documents in compliance with the
Securities Act that may be required in the event the selling shareholders
defaults under any customer agreement with brokers.

   We are required to pay all fees and expenses incident to the registration of
the shares of common stock. We have agreed to indemnify the selling
shareholders against certain losses, claims, damages and liabilities,
including liabilities under the Securities Act. Brokerage commissions and
similar selling expenses, if any, attributable to the sale of shares by the
selling shareholders will be borne by the selling shareholders. The selling
shareholders may agree to indemnify brokers, dealers or agents that
participate in sales by the selling shareholders against certain losses,
claims, damages and liabilities, including liabilities under the Securities
Act.

Item 15.          Indemnification of Directors and Officers

         Chapter 17, Subchapter D of the Pennsylvania Business Corporation Law
of 1988, as amended (the "PBCL") contains provisions permitting indemnification
of officers and directors of a business corporation in Pennsylvania.

         Sections 1741 and 1742 of the PBCL provide that a business corporation
may indemnify directors and officers against liabilities and expenses they may
incur as such in connection with any threatened, pending or completed civil,
administrative or investigative proceeding, provided that the particular person
acted in good faith and in a manner he or she reasonably believed to be in, or
not opposed to, the best interests of the corporation, and, with respect to any
criminal proceeding, had no reasonable cause to believe his or her conduct was
unlawful. In general, the power to indemnify under these sections does not exist
in the case of actions against a director or officer by or in the right of the
corporation if the person otherwise entitled to indemnification shall have been
adjudged to be liable to the corporation unless it is judicially determined
that, despite the adjudication of liability but in view of all the circumstances
of the case, the person is fairly and reasonably entitled to indemnification for
specified expenses.

         Section 1743 of the PBCL provides that the corporation is required to
indemnify directors and officers against expenses they may incur in defending
actions against them in such capacities if they are successful on the merits or
otherwise in the defense of such actions.

         Section 1746 of the PBCL grants a corporation broad authority to
indemnify its directors and officers for liabilities and expenses incurred in
such capacity, except in circumstances where the act or failure to act giving
rise to the claim for indemnification is determined by a court to have
constituted willful misconduct or recklessness.

         Section 1747 of the PBCL permits a corporation to purchase and maintain
insurance on behalf of any person who is or was a director or officer of the
corporation, or is or was serving at the request of the corporation as a
representative of another corporation or other enterprise, against any liability
asserted against such person and incurred by him or her in any such capacity, or
arising out of his or her status as such, whether or not the corporation would
have the power to indemnify the person against such liability under Chapter 17
Subchapter D of the PBCL.

         The Registrant's Bylaws provide a right to indemnification to the full
extent permitted by law, for expenses (including attorney's fees), damages,
punitive damages, judgments, penalties, fines and amounts paid in settlement,
actually and reasonably incurred by any director or officer whether or not the
indemnified liability arises or arose from any threatened, pending or completed



                                      II-1


proceeding by or in the right of the Registrant (a derivative action) by reason
of the fact that such director or officer is or was serving as a director,
officer, employee or agent of the Registrant or, at the request of the
Registrant, as a director, officer, partner, fiduciary or trustee of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, unless the act or failure to act giving rise to the claim for
indemnification is financially determined by a court to have constituted willful
misconduct or recklessness. The Bylaws provide for the advancement of expenses
to an indemnified party upon receipt of an undertaking by the party to repay
those amounts if it is finally determined that the indemnified party is not
entitled to indemnification.

         The Registrant's Bylaws authorize the Registrant to take steps to
ensure that all persons entitled to indemnification are properly indemnified,
including, if the Board of Directors so determines, purchasing and maintaining
insurance.

Item 17.          Undertakings

(a)      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 (the "Securities Act");

                  (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 the 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 a 20% change in the
         maximum aggregate offering price set forth in the "Calculation of
         Registration Fee" table in the effective registration statement;

                  (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;

         provided, however, that paragraphs (1)(i) and (1)(ii) 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 the
registration statement.

                                      II-2


         (2) That, for the purpose of determining any liability under the
Securities Act, 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.

         (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 the offering.

(b)      The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the 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)      That, 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 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 Act and will be governed by the final adjudication of
such issue.

(d)      That,

         (1) For purposes of determining any liability under the Securities Act,
         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

         (2) For the purpose of determining any liability under the Securities
         Act, 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.

                                      II-3
