                                   THE COMPANY

         We specialize in the architecture, design and delivery of wireless
technology and product platforms. Over the course of our corporate history, we
have amassed a substantial and significant library of digital wireless systems
experience and know-how and we hold an extensive worldwide portfolio of patents
in the wireless systems field.

         We market our technologies and solutions capabilities primarily to
telecommunications equipment producers and related suppliers. Our inventions are
embedded into products targeted for the following wireless telecommunications
applications: mobile phones, personal digital assistants, mobile computing
devices, other terminal-end wireless devices, base stations and other
infrastructure equipment. In addition, we license our Time Division Multiple
Access (TDMA) and Code Division Multiple Access (CDMA) patents to equipment
manufacturers worldwide. We are continuing to broaden and deepen our extensive
patent portfolio and body of technical know-how related to wireless technologies
and systems through continuous invention and innovation, while also linking our
licensing activities to emerging product development efforts, particularly in
the area of Wideband CDMA (WCDMA) standards.

         We develop advanced wireless technologies and products that facilitate
voice and data communications. Our current technology development programs are
focused on creating intellectual property and both hardware and software
products for the WCDMA air-interface protocols of the Third Generation (3G)
standards. We are currently developing WCDMA Frequency Division Duplex (FDD) and
WCDMA Time Division Duplex (TDD) technology platforms. Our strategic objective
is to create substantial long-term value as one of the leading developers and
providers of advanced air-interface and full system-on-a-chip technology for the
wireless communications industry. We intend to create a return on our investment
in 3G technologies through technology transfer to customers, the delivery
(either alone or through alliances) of software and hardware products and the
licensing of our intellectual property worldwide. The development of advanced
wireless technologies focused on market requirements is a fundamental element of
our future strategic success and is key to achieving these goals.

                                  RISK FACTORS

         This section highlights specific risks with respect to an investment in
our Company. In analyzing this offering, prospective purchasers should carefully
consider these risks. We caution you that this Prospectus, as well as the
documents that we have filed with the Commission that are incorporated by
reference in this Prospectus, contain forward-looking statements that are based
on management's beliefs and assumptions and on information that is currently
available to us. You should carefully consider the risks and uncertainties
described below and in the documents filed with the Commission that are
incorporated herein by reference before purchasing the Common Stock.

                                      -5-



         Forward-looking statements relied upon by management reflect, among
other things, our current intentions and plans or expectations (i) to broaden
our patent portfolio and body of technical know-how, (ii) to link our licensing
activities to emerging product development efforts, (iii) to deliver (either
alone or through alliances) software and hardware products, and (iv) to engage
in technology transfers and license our intellectual property worldwide. Words
such as "objective" and "intend", variations of such words, and words with
similar meaning or connotations are intended to identify such forward-looking
statements.

         Such statements are subject to risks and uncertainties. We caution
readers that important factors in some cases have affected and, in the future,
could materially affect actual results and cause actual results to differ
materially from the results expressed in any such forward looking statement. You
should not place undue reliance on these forward-looking statements, which apply
on or as of the date of this report. Certain of these risks and uncertainties
are described in greater detail in the Company's Form 10-K for the year ended
December 31, 2001. It should also be noted that risks described as affecting one
forward-looking statement may affect other forward-looking statements. In
addition, other factors may exist that are not detailed below or that are not
fully known to us at this time. We undertake no obligation to publicly update
any forward-looking statements, whether as a result of new information, future
events or otherwise.

Our Technologies May Not Be Widely Deployed
-------------------------------------------

         Our activities are focused on next-generation technologies and products
and therefore begin as research and development work. Accordingly, we are
subject to the risks typically associated with such activities. New
technological innovations generally require a substantial investment before they
are commercially viable, and we may make substantial, non-recoverable
investments in new technologies that may not result in meaningful revenues. For
example, in order to generate revenues and profits from sales of 3G products, we
must continue to make substantial investments and technological innovations. A
significant assumption in our strategic plan is that WCDMA will be widely
deployed in the 3G market. WCDMA may not be deployed as widely as we expect
which could reduce revenue opportunities. A second significant assumption in our
strategic plan is that TDD will be adopted and widely used in the 3G market.
While our inventions and know-how can apply across a broad range of
technologies, our detailed technology and development efforts are primarily
focused on WTDD and FDD. Other digital wireless technologies, particularly
CDMA2000, Wireless LAN (W-LAN), FDD used in data applications, FDD high speed
downlink, and NTDD are expected to be competitive with WTDD. CDMA2000 has been
deployed in parts of Asia and the United States, and such deployment could cause
CDMA2000 to gain significant market share and reduce the opportunities for
WCDMA. W-LAN, which enables users to connect laptops and PDAs to the Internet,
is already being marketed worldwide and is competitive with TDD. If the initial
deployment of FDD for data applications obtains significant market share, or if
FDD high speed downlink gains market acceptance, the niche targeted for WTDD
could be reduced or eliminated. All of these competing technologies also could
impair multi-vendor and operator support for WTDD, key factors in defining
opportunities in the wireless market. There can be no assurance that our

                                      -6-


technology will ultimately have market relevance or be selected by wireless
service providers for their networks or equipment manufacturers. If we determine
that WTDD will not be adopted at all or in a time period we expect, or adopted
in a manner which justifies our continuing investment in the technology, we may
change our strategic plan to reduce or eliminate such continuing investment
and/or to capture more lucrative market opportunities. Additionally, if WTDD is
not adopted and widely used, our strategic plan will require a significant shift
and a portion of our anticipated revenue may be impaired.

Our Future Operating Results are Likely to Fluctuate
----------------------------------------------------

         Our financial condition and operating results have fluctuated
significantly in the past and may fluctuate significantly in the future. These
operating results may continue to fluctuate because (i) our markets are subject
to increased competition from other products and technologies and announcements
of new products and technologies by our competitors; (ii) it is difficult to
predict the timing and amount of licensing revenue associated with past
infringement and new licenses, or the timing, nature or amount of revenues
associated with strategic partnerships; (iii) we may not be able to enter into
additional or expanded strategic partnerships or license agreements, either at
all or on acceptable terms; (iv) the strength of our patent portfolio could be
weakened through patents being declared invalid, our claims being narrowed,
design-arounds, changes to the standards, and adverse court decisions; and (v)
our revenues are in large part dependent on sales by our licensees which is
outside of our control. General economic and other conditions causing a downturn
in the market for our products in development or technology could also adversely
affect our operating results. Nevertheless, we base our decisions regarding our
operating expenses and capital expenditures on a combination of current cash
balances, anticipated cash flow trends and the level of expenditures required to
execute our strategic plan. Because the base level of many of our expenses is
relatively fixed, revenue from a small number of customers could cause our
operating results to vary from quarter to quarter and result in operating
losses. In addition, increased expenses which could result from factors such as
increased litigation costs or actions designed to keep pace with technology and
product market targets could adversely impact near-term profitability. The
foregoing factors are difficult to forecast and these, as well as other factors,
could adversely affect our quarterly or annual operating results.

We Have Substantial Global Competition
--------------------------------------

         Competition in the wireless telecommunications industry is intense.
There can be no assurance that we will be able to successfully compete in our
efforts to license our technology and/or sell our future products, or that our
competitors will not develop new technologies and products that are more
commercially effective than our own. Our products and services face competition
from existing companies providing services comparable to ours and companies
developing and marketing other digital and wireless technologies. (See, "-Our
Technologies May Not Be Widely Deployed".) We face competition from the in-house
development teams at semiconductor corporations and telecommunication equipment
suppliers. It is also possible that new competitors may enter the market. Many
current and potential competitors may have advantages over us, including (a)
existing royalty-free cross-licenses to competing and emerging technologies; (b)
longer operating histories and presence in key markets; (c) greater name
recognition; (d) access to larger customer bases; and (e) greater financial,

                                      -7-


sales and marketing, manufacturing, distribution channels, technical and other
resources. As a result of these factors, these competitors may be more
successful than us. In addition, the slowdown in the global economy and the
anticipated rollout of 3G has forced, and may continue to force, realignment
within the semiconductor industry. Such vertical and horizontal consolidation
could result in increased competition for partnership opportunities.

We Need to Effect Further Technology and Product Development in a Timely Manner
-------------------------------------------------------------------------------

         Our future success will depend on our ability to continue to develop,
introduce and sell new products, technology and enhancements on a timely basis.
Our future success will also depend on our ability to keep pace with
technological developments, satisfy varying customer requirements, price our
products competitively and achieve market acceptance. The introduction of
products embodying new technologies and the emergence of new industry standards
could render our products and technology currently under development obsolete
and unmarketable. If we fail to anticipate or respond adequately to
technological developments or customer requirements, or experience any
significant delays in development, introduction or shipment of our products and
technology in commercial quantities, our competitive position could be damaged.

         Our positioning for the 3G market will require continued significant
investment in research and development. We cannot be sure that we will have
sufficient resources to make such investments, that we will be able to make the
technological advances necessary to achieve these goals, or that the costs
associated with such efforts will be acceptable. Our business, financial
condition and operating results could be materially adversely affected if we are
unable to respond to the need for technological change or if these products or
technologies do not achieve market acceptance when released.

         We may experience technical, financial or other difficulties or delays
related to the further development of our technologies. Delays can be costly,
and if such development efforts are not successful or delays are serious, our
existing and potential strategic relationships could suffer or these strategic
partners could be hampered in marketing efforts of products containing our
technologies. We could experience reduced royalty revenues on such
organizations' products containing our technology and we could miss a critical
market window. Further, failure to meet material obligations under our existing
or potential contracts could result in the other party terminating the
relationship and/or seeking to hold us liable for breach. Moreover, our
technologies are in the development stage, and have not been fully tested in
commercial use. It is possible that they may not perform as expected or may not
be market relevant. In such case, our business, financial condition and
operating results could be adversely affected.

Our Markets are Unpredictable and Subject to Rapid Technological Change
-----------------------------------------------------------------------

         We are positioning our current development projects for the emerging 3G
market. These projects do not have direct bearing on the 2.5G, GPRS, or any
other market which might develop after the 2G market but prior to the
development of the 3G market. The 3G market has and may continue to develop at a
slower rate or pace than we have and do expect and may be of a smaller size than
we expect. For example, the potential exists for 3G preemption by the hangover
of 2.5G solutions now being bought, tested and fielded. In addition, there could
be fewer applications for our technology and products than we expect. Many
factors could affect the rate and pace of 3G market development including, but
not limited to, economic conditions, customer buying patterns, timeliness of
equipment development, pricing of 3G infrastructure and mobile products,

                                      -8-


continued growth in telecommunications services that would be delivered on 3G
devices, and availability of capital for and the high cost of infrastructure
improvements. Failure of the 3G market to materialize to the extent or at the
rate which we expect would reduce our opportunities for sales and licensing and
could materially adversely affect our business, financial condition and
operating results.

         The entire wireless communications market in which we compete is
characterized by rapid technological change, frequent product introductions and
evolving industry standards. Existing technology and products become obsolete
and unmarketable when products using new technologies are introduced and new
industry standards emerge. As a result, marketability and the potential life
cycles of the products and technologies that we are developing cannot be assured
and are difficult to estimate. In addition, new industry standards, falling
prices or technology changes may render the products and/or technologies
obsolete or non-competitive. New technologies and products can fail to become
commercially viable due to lack of market relevance. To be successful, we must
continue to develop new products and technologies that successfully respond to
such changes. We may not be able to successfully predict the market or form
strategic relationships, either at all or on acceptable terms, to enable us to
develop such new products and technologies. Even if we do, we may not be able to
introduce such products or technologies successfully in a timely manner. Missing
a critical market window could reduce or eliminate our ability to capitalize on
the technology and products as to which the window applies.

Certain Events Will Occur Under Two Contracts in the Next Two Years Which Could
Adversely Affect Our Cash Flow And Our Ability to Achieve or Sustain Acceptable
Levels of Profitability
--------------------------------------------------------------------------------

         Revenues attributable to Nokia, a strategic engineering partner,
comprised approximately 42% of total revenue in 2001. In the third quarter of
2001, we amended our development program agreement with Nokia to, among other
things, provide for Nokia's funding of the project up to a maximum of
approximately $58 million. Previous to the amendment, revenue had been reported
on a time and materials basis and we had billed Nokia approximately $46 million
under the contract leaving approximately $12 million of revenue to be
recognized. After the amendment, we recognize revenue under the contract on a
percentage of completion basis. Of the $12 million remaining under the contract
after the amendment, approximately $6.2 million was recognized in 2001, and we
expect to recognize the balance in 2002. We have not, at this time, entered into
any arrangements with Nokia to extend our development relationship and there
should be no expectation that we will do so in the future. Should our costs
associated with the development effort exceed the maximum funding committed by
Nokia, we will continue the development effort needed to complete our
contractual commitments on a self-funded basis and this could adversely affect
both our cash flow and our ability to achieve acceptable levels of
profitability.

         Revenues attributable to Sharp, one of our TDMA patent licensees,
comprised approximately 30% of total revenue in 2001. This license agreement
with Sharp covers PDC and PHS products and expires in mid 2003. Although we will
seek to extend the term of this license with Sharp, there can be no assurance
that we will be successful, either at all or on favorable or comparable terms.
The inability to extend the license could adversely affect both our cash flow
and our ability to achieve or sustain acceptable levels of profitability for the
years beyond 2002.


                                      -9-


We Rely and Intend to Rely on Relationships with Third Parties.
---------------------------------------------------------------

         The successful execution of our strategic plan is partially dependent
on the establishment and success of relationships with equipment producers and
other third parties. Our plan contemplates that these third parties will give us
access to product capability, markets and additional libraries of technology. We
currently have a limited number of such third party relationships. To date we
have not entered into any semi-conductor partnership relating to our TDD
technology. We have only one semi-conductor partner in our FDD technology
development effort, Infineon, and if we commence a FDD Access Stratum
development effort with another semiconductor company for terminal unit
applications, Infineon may engage a third party for the development or
modification of a new FDD Access Stratum. Our failure to enter into such
additional relationships, either on acceptable terms or at all, or our failure
to successfully execute such relationships, could impair our ability to
introduce portions of our technology and resulting products. Further, the
failure to maintain existing relationships and to establish new relationships,
all on satisfactory terms with capable partners, could also adversely affect our
future operating results. In addition, delays in entering into such
relationships could cause us to miss critical market windows.

         Our ability to derive revenues from our FDD development project is
currently largely dependent on Infineon's success in developing the ICs that
incorporate the Joint 3G Protocol Stack, and on Infineon's and our success in
marketing and selling the Joint 3G Protocol Stack independently. Moreover, while
we may independently market and use our own portions of the Joint 3G Protocol
Stack being jointly developed with Infineon, the other anticipated benefits of
the Infineon relationship may be impacted by economic conditions affecting
semi-conductor companies in general and their ability to compete effectively,
Infineon's financial condition and engineering resources, and the market timing
and technological success of the Infineon platform upon which our designs are
based.

         From time to time, certain companies may also assert that their patent,
copyright and other intellectual property rights are also important to the
industry or to us. In that regard, from time to time third parties provide us
with copies of their patents relating to digital wireless technologies and offer
licenses to such technologies. We in turn evaluate such patents and the
advisability of obtaining such licenses. If any of our products were found to
infringe on protected technology, we could be required to redesign such
products, license such technology, and/or pay damages to the infringed party. If
we are unable to license protected technology used in our products and/or if we
cannot economically redesign such products, we could be prohibited from
marketing such products. In such case, our prospects for realizing future income
could be adversely affected.

Our Revenue in the Short and Long Term Depends Upon Our Success in Enforcing
Patent Rights and Protecting Other Intellectual Property
--------------------------------------------------------------------------------

         Our strategic plan depends, over the next several years, upon our
continued ability to generate patent licensing revenue related to the sale by
third parties of handsets and infrastructure compliant with the TDMA digital
cellular standards in use today, among them GSM, IS-54/136, PDC and PHS (2G
products). Our ability to collect such revenue is subject to a number of risks.
First, major telecommunications equipment manufacturers have challenged, and we
expect will continue to challenge, the validity of ITC's patents. In some
instances, certain of ITC's patent claims have been declared invalid or
substantially narrowed. While ITC continues to maintain a worldwide portfolio of
patents that it believes are valid and infringed, and while we intend to
vigorously defend and enforce such patents, we cannot assure that the validity
of our patents will be maintained or that any of our key patents will be
determined to be applicable to any 2G or 3G product. Any significant adverse
finding as to the validity or scope of ITC's key patents could result in the

                                      -10-


loss of patent licensing revenue from existing licensees and could substantially
impair our ability to secure new patent licensing arrangements. Additionally,
while we license a portfolio of patents, 2G licensing revenues are or are
expected to be adversely impacted by the decline of the 2G market coupled with
the expiration of certain of our TDMA patents in the coming years.

         In the long term, our strategic plan depends upon our ability to
generate patent licensing revenue from the sale by third parties of products
compliant with the standards adopted for 3G (3G Products). Our ability to
generate such revenue is subject to certain risks. First, many of the inventions
which we believe will be employed in 3G Products are the subject of patent
applications which have not yet been issued by the relevant patent reviewing
authorities. While we intend to vigorously defend such patents, we cannot assure
that these patent applications will be granted or that the resulting patents
will be infringed by 3G Products. Second, we expect that the validity of our
patents will be challenged, and that we will be required to enforce our patents
against parties that refuse to take a license under our patents. While we intend
to vigorously defend and enforce our patents, we cannot assure that the validity
of our patents will be maintained or that any of our patents will be determined
to be applicable to any 3G Product. Finally, our ability to generate 3G patent
licensing revenue is dependent on our licensees' success in selling 3G Products.
This, in turn, may be affected by many other factors, some of which are
described in this "Risk Factors" section, including global economic conditions,
buying patterns of end users, competition and the changing technology and market
landscapes.

         In addition, the cost of defending our intellectual property has been
and may continue to be significant. Litigation may be required to enforce our
intellectual property rights, protect our trade secrets, enforce confidentiality
agreements, or determine the validity and scope of proprietary rights of others.
As a result of any such litigation, we could lose our proprietary rights and/or
incur substantial unexpected operating costs. Any action we take to protect our
intellectual property rights could be costly and could absorb significant
management time and attention which, in turn, could negatively impact our
results of operations. Moreover, third parties could circumvent the patents held
by our wholly-owned subsidiary, ITC, through design changes. Any of these events
could adversely affect our prospects for realizing future income.

         Together with ITC, we are currently engaged in a significant patent
infringement litigation with Ericsson, Inc. (Ericsson) over certain of ITC'S
patents. During the course of this litigation (or a future yet unidentified and
unfiled litigation, should such litigation arise), certain of ITC's key patents
could be found to be invalid or not infringed or its patent claims could be
narrowed. Any such adverse finding as to the validity or scope of ITC's key
patents could result in the loss of patent licensing revenue from existing
licensees and could substantially impair our ability to secure new patent
licensing arrangements.

Our License Agreements Contain Provisions which Could Impair Our Ability to
Realize Licensing Revenues
--------------------------------------------------------------------------------

                  Certain of our licenses contain provisions which could, in
certain events, cause the licensee's obligation to pay royalties to us to be
reduced, terminated or suspended for an indefinite period, with or without the
accrual of the royalty obligation. In addition, certain of our licensees had, in
the past, stated, among other things, that the outcome of a prior litigation
over ITC's patents materially impacted the royalties due under their license
agreements and have refused to pay royalties under their license agreements.
While we believe that these positions have been meritless, similar positions
could be asserted in the event that a licensee's obligation to pay royalties to
us in the future is either terminated or indefinitely suspended, or in the event

                                      -11-


that ITC's patents are held invalid or unenforceable, and these positions could
be found to have merit. The assertion or validity of such positions could
interfere with ITC's ability to secure new licenses or to generate recurring
licensing revenue under the existing agreements.

We Face Risks From Doing Business in Global Markets
---------------------------------------------------

         A significant part of our strategy involves our continued pursuit of
growth opportunities in a number of international markets. In doing so, we are
subject to the effects of a variety of uncontrollable and changing factors,
including: difficulty in protecting our intellectual property in foreign
jurisdictions; inability to enter foreign markets; government regulations,
tariffs and other applicable trade barriers; currency control regulations;
social, economic and political instability; natural disasters, acts of terrorism
and war; potentially adverse tax consequences; inability to enforce contractual
commitments abroad; and general delays in remittance and difficulties of
collecting non-U.S. payments. In addition, we are also subject to risks specific
to the individual countries in which our customers, our licensees and we do
business.

         A long lasting downturn in the global economy that impacts the wireless
communications industry could negatively affect our revenues and operating
results. The global economy is in a slowdown that has had wide-ranging effects
on our licensees and the markets that we target, particularly wireless equipment
manufacturers and network operators. In particular, recent economic weakness in
Japan, from which a significant portion of our 2001 revenue was derived, has and
may continue to lead to decreased sales of licensed products. This downturn has
had and is expected to continue to have a negative effect on, among other
things, the ability and willingness of companies to invest in technological and
product development, and the sales of our licensees (which, in turn, affects our
revenues). We cannot predict the depth or duration of this downturn, and if it
grows more severe or continues for a long period of time, our ability to
increase or maintain our revenues and other operating results may be impaired.

Consolidations in the Wireless Communications Industry Could Adversely Affect
Our Business
--------------------------------------------------------------------------------

         The wireless communications industry has experienced consolidation of
participants, and this trend may continue. ITC's licensing opportunities are
affected by the increasing concentration of the wireless industry, particularly
as to infrastructure, which results in a substantial portion of the licensing
opportunities being concentrated in a small number of non-licensed
manufacturers, many of whom are opposing the validity of ITC's patents in
multiple forums. In addition, certain business combinations may result in the
loss or diminution of existing royalty obligations. Further, if wireless
carriers consolidate with companies that utilize technologies competitive to our
technologies, we may lose market opportunities.

We Depend on Sufficient Engineering Resources
---------------------------------------------

         Competition for qualified and talented individuals with engineering
experience in emerging technologies, like WCDMA, is intense. There can be no
assurance that we will be able to attract and retain a satisfactory number of
such individuals. The failure to attract and retain highly qualified personnel
could interfere with our ability to undertake additional technology and product
development efforts as well as our ability to meet our strategic objectives.


                                      -12-


Market Predictions are Forward-Looking in Nature
------------------------------------------------

         Our market strategy is based on our own predictions and on analyst,
industry observer and expert predictions, which are forward-looking in nature
and are inherently subject to risks and uncertainties. Many factors could affect
these predictions including, but not limited to, the validity of their and our
assumptions, the timing and scope of the 3G market, economic conditions,
customer buying patterns, timeliness of equipment development, pricing of 3G
products, growth in wireless telecommunications services that would be delivered
on 3G devices, and availability of capital for infrastructure improvements. If
any of these predictions are wrong, our strategic plan may require a significant
shift and our operating results could be adversely affected.

We Face Risks from Terrorist, Cyber and Other Attacks
-----------------------------------------------------

         None of our properties or data were damaged or compromised as a result
of the terrorist attacks that occurred in the United States on September 11,
2001. Our operations during the period that followed suffered only minor
disruption such as delayed travel. However, we could be impacted, in the future,
by a terrorist, cyber or other attack either directly or indirectly through our
customers or vendors.

If Wireless Handsets Pose Health and Safety Risks, Demand for Our Products in
Development and Those of Our Licensees and Customers Could Decrease
--------------------------------------------------------------------------------

         Media reports and certain studies have suggested that radio frequency
emissions from wireless handsets may be linked to various health concerns and
may interfere with various electronic medical devices. If concerns over radio
frequency emissions grow, this could discourage the use of wireless handsets,
and cause a decrease in demand for our products and those of our licensees and
customers. There are also some safety risks associated with the use of wireless
handsets while driving. Concerns over these safety risks and the effect of any
legislation that may be adopted in response to these risks could reduce demand
for our products in development and those of our licensees and customers.

Our Stock Price is Volatile
---------------------------

         Historically, market prices for securities of companies involved in the
wireless telecommunications industry have been volatile. In addition, market
prices for the Common Stock have historically been particularly volatile due, in
part, to the Company's history of quarterly fluctuations of revenues and
operating results. Announcements of, among other things, technological
innovations or new commercial products by the Company or its competitors,
developments concerning proprietary technologies, results of patent enforcement
activities, regulatory developments in both the United States and other
countries, and global and national economic and political factors, as well as
period-to-period fluctuations in financial results, may have a significant
impact on the market price of the Common Stock.

                              PLAN OF DISTRIBUTION

         The Company is registering the Shares on behalf of the Selling
Shareholders. As used herein, "Selling Shareholders" includes donees, pledgees
or other transferees selling shares received from the named Selling Shareholders
after the date of this prospectus. All costs, expenses and fees in connection
with the registration of the Shares offered hereby will be borne by the Company.
Brokerage commissions and similar selling expenses, if any, attributable to the
sale of Shares will be borne by the Selling Shareholders. Sales of Shares may be
effected by Selling Shareholders from time to time in one or more types of
transactions (which may include block transactions) on the Nasdaq National
Market, in negotiated transactions, through put or call options transactions
relating to the Shares, through short sales of Shares, or a combination of such
methods of sale, at market prices prevailing at the time of sale, or at
negotiated prices. Such transactions may or may not involve brokers or dealers.
The Selling Shareholders have advised the Company that they have not entered
into any agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of their securities, nor is there an
underwriter or coordinating broker acting in connection with the proposed sale
of Shares by the Selling Shareholders.

         The Selling Shareholders may effect such transactions by selling Shares
directly to purchasers or to or through broker-dealers, which may act as agents
or principals. Such brokers-dealers may receive compensation in the form of
discounts, concessions, or commissions from the Selling Shareholders and/or the
purchasers of Shares for whom such broker-dealers may act as agents or to whom
they sell as principal, or both (which compensation as to a particular
broker-dealer might be in excess of customary commissions).

         The Selling Shareholders and any broker-dealers that act in connection
with the sale of Shares might be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act, and any commissions received by such
broker-dealers and any profit on the resale of Shares sold by them while acting
as principals might be deemed to be underwriting discounts or commissions under
the Securities Act. The Company has agreed to indemnify the Selling Shareholders
against certain liabilities, including liabilities arising under the Securities
Act. The Selling Shareholders may agree to indemnify any agent, dealer or
broker-dealer that participates in transactions involving sales of the Shares
against certain liabilities, including liabilities arising under the Securities
Act.

         Because the Selling Shareholders may be deemed to be an "underwriter"
within the meaning of Section 2(11) of the Securities Act, the Selling
Shareholders will be subject to the prospectus delivery requirements of the
Securities Act. The Company has informed the Selling Shareholders that the
anti-manipulative provisions of Regulation M promulgated under the Exchange Act
may apply to their sales in the market.

         The Selling Shareholders also may resell all or a portion of the Shares
in open market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of such Rule
144.

                                      -16-



         Upon the Company being notified by any of the Selling Shareholders that
any material arrangement has been entered into with a broker-dealer for the sale
of Shares through a block trade, special offering, exchange distribution or
secondary distribution or a purchase by a broker or dealer, a supplement to this
prospectus will be filed, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing (i) the name of each such Selling Shareholder and of
the participating broker-dealer(s), (ii) the number of shares involved, (iii)
the price at which such Shares were sold, (iv) the commissions paid or discounts
or concessions allowed to such broker-dealer(s), where applicable, (v) that such
broker-dealer(s) did not conduct any investigation to verify the information set
out or incorporated by reference in this prospectus and (vi) other facts
material to the transaction. In addition, upon the Company being notified by any
of the Selling Shareholders that a donee, pledgee or other transferee intends to
sell more than 500 shares, a supplement to this Prospectus will be filed.

                                  LEGAL MATTERS

         The validity of the Common Stock registered hereunder has been passed

Item 15. Indemnification of Directors and Officers

         Sections 1741-1750 of the BCL and the Company's By-Laws provide for
indemnification of the Company's directors and officers and certain other
persons. Under Sections 1741-1750 of the BCL, directors and officers of the
Company may be indemnified by the Company against all expenses incurred in
connection with actions (including, under certain circumstances, derivative
actions) brought against such director or officer by reason of his or her status
as a representative of the Company, or by reason of the fact that such director
or officer serves or served as a representative of another entity at the
Company's request, so long as the director or officer 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 Company. As permitted under the BCL, the Company's By-Laws
provide that the Company shall indemnify directors and officers against all
expenses incurred in connection with actions (including derivative actions)
brought against such director or officer by reason of the fact that he or she is
or was a director or officer of the Company, or by reason of the fact that such
director or officer serves or served as an employee or agent of any entity at
the Company's request, unless the act or failure to act on the part of the
director or officer giving rise to the claim for indemnification is determined
by a court in a final, binding adjudication to have constituted willful
misconduct or recklessness.

         23.1     Consent of Independent Public Accountants (see page II-20).

Item 17. Undertakings.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the provisions discussed in Item 15 of this Registration
Statement, or otherwise, the Company has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of the
Company in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person with the securities being
registered, the Company will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

         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; (ii) to reflect in the prospectus any facts or
events arising after the effective date of this 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 and 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 percent
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; provided, however, that clauses
(i) and (ii) above do not apply if the information required to be included in a
post-effective amendment by those clauses is contained in periodic reports filed
by the Company pursuant to Section 13 or Section 15(d) of the Exchange Act that
are incorporated by reference in this Registration Statement; (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; 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 the
offering.

         The Company hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act 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.
