                             SUMMARY OF THE BUSINESS

Company Overview

Sonic Foundry(R), Inc. was founded in 1991, incorporated in Wisconsin in March
1994 and merged into a Maryland corporation of the same name in October 1996. We
conduct our business through Sonic Foundry, Inc. and three subsidiaries: Sonic
Foundry Media Services, Inc., International Image Services, Inc. d/b/a Sonic
Foundry Media Services and Sonic Foundry Media Systems, Inc. f/k/a Sonic Foundry
Systems Group, Inc., which was created as the result of an acquisition completed
in October 2001. Our executive offices are located at 1617 Sherman Avenue,
Madison, Wisconsin, 53704 and our telephone number is (608) 256-3133. Our
corporate website is http://www.sonicfoundry.com.

Our Media Software division writes software code and develops software solutions
for the creation, manipulation, and delivery of digital media. Sonic Foundry
software includes the ACID(TM) line of products for digital music creation, the
Sound Forge(R) line of products for digital audio editing, Vegas(R) Audio for
digital audio creation and editing, Vegas(R) Video and VideoFactory(TM) for
digital video editing and "Loops For ACID", which are CD compilations of digital
audio for use with ACID.

Our Media Services division incorporates our existing technology and audio and
video signal processing algorithms, including proprietary automation tools.
Primary services include translating analog or digital tapes, CDs, films and
other audio and video media into various compression and Internet streaming file
formats, including multiple compression rates. Add-on services involve cleaning
or filtering recordings for improved quality. In addition, we provide technical
services to the television program distribution market, including preprocessing
algorithms and technologies used for standards conversions (such as NTSC
broadcast format to PAL broadcast format and vise versa) as well as improving
analog to digital conversions.

Our Media Systems division was formed on October 15, 2001, when our wholly owned
subsidiary, Sonic Foundry Media Systems, Inc. acquired the assets and assumed
certain

                                        3



liabilities of MediaSite, Inc MediaSite derived its core technology from a
Carnegie Mellon University research effort funded by government agencies and
private corporations. Using MediaSite's technology (hereafter, the "Media
Systems technology "), we provide software solutions for the indexing, searching
and retrieving of digital media assets such as pictures, text, audio and video
clips, as well as solutions for automating publishing, managing and accessing
digital media.

                                  RISK FACTORS

THE OVERALL ECONOMIC PROBLEMS IN THE TECHNOLOGY INDUSTRY HAVE WEAKENED OUR
ABILITY TO RAISE CAPITAL AND ACHIEVE PROFITABLE OPERATIONS.

     The technology industry has been in a severe economic recession since
mid-2000. Among other things, spending in the technology sector has shrunk, and
stock prices have dropped precipitously. This has impacted us in many ways,
including, most significantly, a drop in the demand for our products and
services and a steep plunge in the market price of our common stock. In
response, we have made significant cuts in our work force and in other areas,
incurring a restructuring charge of $3.8 million in December 2000 and $1.2
million in September 2001. The technology industry in general, and our company
in particular, has still not recovered from the economic recession. We lost
$50.3 million in the first two quarters of fiscal 2002, including the cumulative
effect of a change in accounting principle, and we may continue to lose money
for the foreseeable future. In addition, because of the extreme weakness in the
price of our common stock, our access to capital markets has been severely
restricted. Although we believe we have sufficient cash for at least the next
twelve months, we cannot continue in business indefinitely without achieving a
profit or generating cash from operations.

OUR EVOLVING MIX OF BUSINESS MAKES IT DIFFICULT TO EVALUATE OUR COMPANY.

     We were incorporated in 1994 and became a public company in 1998. For the
first several years of our existence, we focused exclusively on selling software
products. In fiscal 2000, we began, primarily through acquisitions, to focus on
our media services group. In October 2001, we purchased MediaSite, Inc., thereby
adding a third business segment - media systems - to our company. Due to our
evolving business mix, an investor will have limited insight into trends that
may emerge and affect our business. In addition, the revenue and income
potential of the media systems business is unproven.

WE MAY CONTINUE TO INCUR NET LOSSES.

     We have incurred significant losses since our inception, $49.9 million in
2001; $34.9 million in 2000; $6.0 million in 1999; and $0.6 million in 1998, and
we may never become profitable. As of March 31, 2002, we had an accumulated
deficit of $142.5 million.

     We anticipate achieving breakeven during fiscal year 2003. However, we will
continue to incur losses through fiscal year 2003 if:


                                        4




        .     The investors in our $7,125,000 offering of convertible
              subordinated debt do not convert their notes into common stock,
              requiring continued amortization of debt discount.
              Due to the economics of the transaction, we do not expect any
              substantial conversion until our stock reaches approximately
              $2.45; it currently trades at approximately $1.50;

        .     We are unable to continue to grow our revenues; or

        .     We increase our expenses above their current level.

IF OUR INVESTORS DO NOT CONVERT THEIR NOTES, WE WILL NEED TO RAISE ADDITIONAL
WORKING CAPITAL.

     Our recent cash shortfall was approximately $300,000 per month. Based on
our current cash situation, we anticipate having sufficient working capital for
at least the next twelve months. However, this forecast depends upon a
sufficient number of investors converting their notes. If they fail to do so, we
will need to obtain additional funds by the early part of next fiscal year to be
able to make principal and interest payments on the notes. If no investors
convert, these payments will be $330,000 per month, which will require us to
raise additional funds. If we cannot do so, we may be required to curtail or
scale back our operations.

WE MAY NOT EARN REVENUES SUFFICIENT TO REMAIN IN BUSINESS.

     Our ability to become profitable depends on whether we can sell our
products, services and systems for more than it costs to produce and support
them. Our future sales also need to provide sufficient margin to support our
ongoing operating activities. The success of our revenue model will depend upon
many factors including:

        .     The extent to which consumers and businesses use our products,
              services and systems;

        .     Our ability to introduce new digital media services and
              applications;

        .     Our success in adapting to changes in the marketplace; and

        .     Our ability to upgrade and enhance our technologies to accommodate
              expanded digital media service and application offerings.

     Because of the recession in the technology market, the early stage of our
media systems business segment, and the evolving nature of our business, we
cannot predict whether our revenue model will prove to be viable, whether demand
for our products, services and systems will materialize at the prices we expect
to charge, or whether current or future pricing levels will be sustainable.

WE MUST CONTINUALLY DEVELOP NEW PRODUCTS, SERVICES AND SYSTEMS WHICH APPEAL TO
OUR CUSTOMERS.

     Our products, services and systems are subject to rapid obsolescence and
our future success will depend upon our ability to develop new products,
services and systems that meet


                                        5




changing customer and marketplace requirements. There is no assurance that we
will be able to successfully:

           .  Identify new product, service and system opportunities; or

           .  Develop and introduce new products, services and systems to market
              in a timely manner.

         Even if we are able to identify new opportunities, our working capital
constraints limit our ability to pursue them. If we are unable to identify and
develop and introduce new products, services and systems on a timely basis,
demand for our products, services and systems will decline.

         We must identify and develop markets for our products, services and
systems. A suitable market for our products, services and systems may not
develop or, if it does develop, it may take years for the market to become large
enough to support significant business opportunities. Even if we are able to
successfully identify, develop, and introduce new products, services and
systems, there is no assurance that a suitable market for these products,
services and systems will materialize. The following factors could affect the
success of our products, services and systems and our ability to address
sustainable markets:

           .  The failure of our business plan to accurately predict the
              types of products, services and systems the future marketplace
              will demand;

           .  Our limited working capital may not allow us to commit the
              resources required to adequately support the introduction of
              new products, services and systems;

           .  The failure of our business plan to accurately predict the
              estimated sales cycle, price and acceptance of our products,
              services and systems; or

           .  The development by others of products, services and systems
              that makes our products, services and systems noncompetitive
              or obsolete.

COMMERCIAL FAILURE OF INTERNET-BASED BUSINESSES COULD REDUCE DEMAND FOR OUR
DIGITAL MEDIA SERVICES AND SYSTEMS.

         The substantial proportion of customers for our digital media services
have been Internet-based businesses and we expect that in the future, a majority
of our customers will be these types of businesses.

         Our business prospects and revenues would be harmed by the commercial
failure or diminished commercial prospects of these or like customers. In
addition, if such customers have difficulty raising additional capital to fund
their operations, our business prospects and revenues would be harmed.


                                        6




THERE IS A LOT OF COMPETITION IN THE MARKET FOR DIGITAL MEDIA SYSTEMS AND
SERVICES, WHICH COULD LOWER THE DEMAND FOR OUR SYSTEMS AND SERVICES.

         The market for digital media services and systems is relatively new,
and we face competition from in-house digital services by potential customers,
other vendors that provide outsourced digital media services and other companies
that directly provide digital media applications. If we do not compete
effectively or if we experience reduced market share from increased competition,
our business will be harmed. In addition, the more successful we are in the
emerging market for Internet media services and systems, the more competitors
are likely to emerge including turnkey Internet media application and service
providers; streaming media platform developers; digital music infrastructure
providers; digital media applications service providers (including for digital
musical subscription) and video post production houses.

         The presence of these competitors could reduce the demand for our
systems and services, and we may not have the financial resources to compete
successfully.

OUR MEDIA SERVICES AND SYSTEMS BUSINESS MODEL IS UNPROVEN, MAKING IT DIFFICULT
TO FORECAST OUR REVENUES AND OPERATING RESULTS.

         Our services and systems business model is based on the premise that
digital media content providers and developers will outsource a large percentage
of their digital service and content management needs. Our potential customers
may rely on internal resources for these needs. In addition, technological
advances may render an outsourced solution unnecessary, particularly as new
media content is created in a digital format. Market acceptance of our services
may depend in part on reductions in the cost of our services so that we may
offer a more cost effective solution than both our competitors and our customers
doing the work internally. Our cost reduction efforts may not allow us to keep
pace with competitive pricing pressures and may not lead to improved gross
margins. In order to remain competitive, we expect to reduce the cost of our
services through design and engineering changes. We may not be successful in
reducing the costs of providing our services.

THE TECHNOLOGY UNDERLYING OUR PRODUCTS, SERVICES AND SYSTEMS IS COMPLEX AND MAY
CONTAIN UNKNOWN DEFECTS THAT COULD HARM OUR REPUTATION, RESULT IN PRODUCT
LIABILITY OR DECREASE MARKET ACCEPTANCE OF OUR PRODUCTS, SERVICES AND SYSTEMS.

         The technology underlying our digital media products, services and
systems is complex and includes software that is internally developed and
software licensed from third parties. These software products may contain errors
or defects, particularly when first introduced or when new versions or
enhancements are released. We may not discover software defects that affect our
current or new services and applications or enhancements until after they are
sold. Furthermore, because our digital media services and systems are designed
to work in conjunction with various platforms and applications, we are
susceptible to errors or defects in third-party applications that can result in
a lower quality product for our customers. Any defects in our products, services
and systems could:


                                        7





              .    Damage our reputation;

              .    Cause our customers to initiate product liability suits
                   against us;

              .    Increase our product development resources;

              .    Cause us to lose sales; and

              .    Delay market acceptance of our digital media services and
                   systems.

         We do not possess product liability insurance, and our errors and
omissions coverage is not likely to be sufficient to cover our complete
liability exposure.

WE RELY ON STRATEGIC RELATIONSHIPS TO PROMOTE OUR SERVICES AND PRODUCTS; IF WE
FAIL TO MAINTAIN OR ENHANCE THESE RELATIONSHIPS, OUR ABILITY TO SERVE OUR
CUSTOMERS AND DEVELOP NEW SERVICES AND APPLICATIONS COULD BE HARMED.

         Our business depends, in part, upon relationships that we have with
strategic partners such as MicroSoft, RealNetworks, Sony, Carnegie Mellon
University and Fraunhofer Institute. We rely, in party, on strategic
relationships to help us:

              .    Maximize the acceptance of our products by customers through
                   distribution arrangements;

              .    Increase the amount and availability of compelling media
                   content on the Internet to help boost demand for our products
                   and services;

              .    Increase awareness of our Sonic Foundry and MediaSite brands;
                   and

              .    Increase the performance and utility of our products and
                   services.

         We would be unable to realize many of these goals without the
cooperation of these partners. We anticipate that the efforts of our strategic
partners will become more important as the availability and use of multimedia
content on the Internet increases. For example, we may become more reliant on
strategic partners to provide more secure and easy-to-use electronic commerce
solutions and build out the necessary infrastructure for media delivery. Due to
the evolving nature of the Internet media infrastructure market, we will need to
develop additional relationships to adapt to changing technologies and standards
and to work with newly emerging companies with whom we do not have pre-existing
relationships. The loss of our existing strategic relationships, the inability
to find other strategic partners or the failure of our existing relationships to
achieve meaningful positive results could make it difficult to strengthen our
technology development and to increase the adoption of our products and
services.

IN OUR SOFTWARE SEGMENT, WE RELY UPON DISTRIBUTORS TO INCREASE OUR MARKET
PENETRATION SO THE LOSS OF ONE OR MORE DISTRIBUTORS, OR THE
RETURN BY THE DISTRIBUTORS OF A LARGE AMOUNT OF OUR PRODUCT, WOULD HARM OUR
SALES.

         We have contracts with Navarre Corporation, and other U.S. companies,
that distribute our software products to various computer resellers, value-added
resellers, catalog distributors and smaller retail outlets. Navarre Corporation
accounted for 14% of total revenues and 24% of software revenues for fiscal
2001. Our contract with Navarre requires us to accept the return of any of our
products that it does not sell and to credit it for the value of these products.
It also provides Navarre with protection for the value of their inventory in the
event that we lower our prices. If these distributors fail to continue to carry
our products, return large quantities of our products to us, or competitive
pressures require us to lower the prices of the products that we supply to them,
our business will suffer.

WE DEPEND ON A LIMITED NUMBER OF CUSTOMERS FOR A SIGNIFICANT PROPORTION OF OUR
REVENUES SO THE LOSS OF, OR DELAY IN PAYMENT FROM, ONE OR A SMALL NUMBER OF
CUSTOMERS COULD HARM OUR SALES.

         A limited number of customers have accounted for a majority of our
revenues in our media services segment and will continue to do so for the
foreseeable future. During the year ended September 31, 2001, two of our
customers in that segment accounted for approximately 23% of our media services
revenue. We believe that a small number of customers will likely continue to
account for a significant percentage of our media services revenues for the
foreseeable future. Due to high revenue concentration among a limited number of
customers, the cancellation, reduction or delay of a large customer order or our
failure to timely complete or deliver a project during a given quarter will
reduce revenues for the quarter. In addition, if any customer fails to pay
amounts it owes us, or if we lose a key customer, our sales will suffer.

DUE TO OUR LICENSE AGREEMENT WITH CARNEGIE MELLON UNIVERSITY, WE MAY FACE
COMPETITION IN OUR PUBLISHER(TM) PRODUCT AND WE MAY LOSE THE ABILITY TO SELL
THAT PRODUCT IN THE FUTURE.

         Our Publisher(TM) product is based in part on licensed technology from
Carnegie Mellon. As part of the MediaSite transaction we acquired a nonexclusive
license to use certain technology in that product and have recently negotiated
an exclusive license as to certain competitors. Because the exclusivity is
limited to a defined list of competitors, a risk exists that Carnegie Mellon
could license the technology to another party that is not currently a named
competitor, but could become competitive with us. Moreover, if the License
Agreement were to terminate before the underlying patents expired, we would lose
the ability to sell the products covered by the License Agreement.


                                        9




WE MAY NOT BE SUCCESSFUL IN PROTECTING OUR INTELLECTUAL PROPERTY AND PROPRIETARY
RIGHTS.

         Our inability to protect our proprietary rights, and the costs of doing
so, could harm our business. Our success and ability to compete partly depends
on the superiority, uniqueness or value of our technology, including both
internally developed technology and technology licensed from third parties. To
protect our proprietary rights, we rely on a combination of trademark, patent,
copyright and trade secret laws, confidentiality agreements with our employees
and third parties and "shrink wrap" licenses. Recently, we have undertaken
additional efforts to identify which of our proprietary processes and algorithms
may be patentable, and we currently have several patent applications pending
with the U.S. Patent and Trademark Office. If patents are not issued as a result
of any of these applications, or if we cannot afford to enforce them, other
parties may infringe on our proprietary rights.

         Despite our efforts to protect our proprietary rights, unauthorized
parties may copy or infringe aspects of our technology, products, services or
trademarks, or obtain and use information we regard as proprietary. In addition,
others may independently develop technologies that are similar or superior to
ours, which could reduce the value of our intellectual property.

         Companies in the computer industry have frequently resorted to
litigation regarding intellectual property rights. We may have to litigate to
enforce our intellectual property rights or to determine the validity and scope
of other parties' proprietary rights.

         We face the risk that our customers might not have all necessary
ownership or license rights in the content for us to perform our encoding
services. Any alleged liability could harm our business by damaging our
reputation, requiring us to incur legal costs in defense, and exposing us to
awards of damages and costs and diverting management's attention.

         Because we host audio and video content on Web sites for customers and
provide services related to digital media content, we face potential liability
or alleged liability for negligence, infringement of copyright, patent, or
trademark rights, defamation, indecency and other claims based on the nature and
content of the materials we host.


                                       10




         Third parties may claim infringement by us with respect to past,
current, or future technologies. If a third party's claim of intellectual
property right infringement were to prevail, we could be forced to pay damages,
comply with injunctions, or halt distribution of our products while we
re-engineer them or seek licenses to necessary technology, which might not be
available on reasonable terms. We could also be subject to claims for
indemnification resulting from infringement claims made against our customers
and strategic partners, which could increase our defense costs and potential
damages. In addition, we have agreed to indemnify certain distributors and
original equipment manufacturers, or OEMs, for infringement claims of other
parties. If these other parties sue the distributors or OEMs, we may be
responsible for defending the lawsuit and for paying any judgment that may
result.



         WE MAY BE UNABLE TO RETAIN TECHNOLOGY LICENSED OR OBTAINED FROM THIRD
PARTIES AND STRATEGIC PARTNERS.


         We rely upon licenses from third parties and strategic partners for
some of our technologies. These companies that license the technologies to us
may decide to discontinue the licenses at any time. If they do so, our business
may suffer



WE MAY BE UNABLE TO OBTAIN THE EXPECTED BENEFITS OF OUR RECENT ACQUISITIONS.



         Our acquisition of certain assets of MediaSite, Inc., which was
completed in October 2001, will require devoting our resources to setting up a
new media systems segment. In addition, in February 2002, we acquired certain
assets of Digital Savant, Inc.



         We may not be able to successfully assimilate the personnel,
technology, operations and customers of these acquisitions into our business. In
addition, we may fail to achieve the anticipated synergy from these
acquisitions, including product, systems and software development, and other
operational synergies. The integration process of these businesses may further
strain our existing financial and managerial controls and reporting systems and
procedures. This may result in the diversion of management and financial
resources from our core business objectives.


         In addition, it is possible that an unforeseen liability may arise from
our acquisition of these companies and result in a claim against us.



OUR REVENUES FROM OUR FOREIGN CUSTOMERS ARE SUBJECT TO ADDITIONAL RISKS ARISING
FROM FOREIGN OPERATIONS.



         We maintain a media services facility in Toronto, Canada, which
provides services primarily to Canadian and other international customers and we
distribute our software products in approximately 30 countries through 30
international distributors. Net revenues from international customers accounted
for 11% of total net revenues for the six-month period ended March 31, 2002.



         We are subject to the normal risks of doing business internationally.
These risks include:


                                       11




            .  Unexpected changes in laws or regulatory requirements.

            .  Political instability.

            .  Export and import restrictions.

            .  Actions by third parties such as discount pricing and business
               techniques unique to foreign countries.

            .  Tariffs and trade barriers and limitations on fund transfers.

            .  Longer payment cycles and problems in collecting accounts
               receivable.

            .  Potential adverse tax consequences.

            .  Exchange rate fluctuations.

            .  Economic conditions including inflation, high tariffs, or wage
               and price controls.

            .  Increased risk of piracy and limits on our ability to enforce our
               intellectual property rights.



WE MAY BE SUBJECT TO ASSESSMENT OF SALES AND OTHER TAXES FOR THE SALE OF OUR
PRODUCTS, LICENSE OF TECHNOLOGY OR PROVISION OF SERVICES.



         We may have to pay past sales or other taxes that we have not collected
from our customers. We do not currently collect sales or other taxes on the sale
of our products, license of technology or provision of services in states and
countries other than Wisconsin. The federal Internet Tax Freedom Act, passed in
1998, imposes a three-year moratorium on discriminatory sales taxes on
electronic commerce, which was recently extended for 2 additional years. We
cannot assure you that this moratorium will be re-extended. Further, foreign
countries or, following the moratorium, one or more states, may seek to impose
sales or other tax obligations on companies that engage in such activities
within their jurisdictions. Our business would suffer if one or more states or
any foreign country were able to require us to collect sales or other taxes from
current or past sales of products, licenses of technology or provision of
services, particularly because we would be unable to go back to customers to
collect sales taxes for past sales and may have to pay such taxes out of our own
funds.



THE CONCENTRATION OF OWNERSHIP BY OUR AFFILIATED STOCKHOLDERS MAY DELAY OR
PREVENT ANY MERGER OR TAKEOVER OF THE COMPANY, WHICH MAY LIMIT THE AMOUNT OF
PREMIUM A STOCKHOLDER WOULD OTHERWISE OBTAIN ON HIS COMMON STOCK.



         Certain of our existing stockholders have significant influence over
our management and affairs, which they could exercise against your best
interests. As of March 30, 2002, our officers and directors, together with
entities that may be deemed affiliates of or related to such persons or
entities, beneficially owned over 30% of our outstanding common stock. As a
result, these


                                       12




stockholders, acting together, may be able to influence significantly our
management and affairs and matters requiring stockholder approval, including the
election of directors and approval of significant corporate transactions.
Accordingly, this concentration of ownership may have the effect of impeding a
merger, consolidation, takeover or other business consolidation involving us, or
discouraging a potential acquiror from making a tender offer for our shares.
This concentration of ownership could also adversely affect our stock's market
price or lessen any premium over market price that an acquiror might otherwise
pay.



PROVISIONS OF OUR CHARTER DOCUMENTS AND MARYLAND LAW COULD ALSO DISCOURAGE AN
ACQUISITION OF OUR COMPANY THAT WOULD BENEFIT OUR STOCKHOLDERS.



     Provisions of our articles of incorporation and by-laws may make it more
difficult for a third party to acquire control of our company, even if a change
in control would benefit our stockholders. Our articles authorize our board of
directors, without stockholder approval, to issue one or more series of
preferred stock, which could have voting and conversion rights that adversely
affect or dilute the voting power of the holders of common stock. Furthermore,
our articles of incorporation provide for classified voting, which means that
our stockholders may vote upon the retention of only one or two of our six
directors each year. Moreover, Maryland corporate law restricts certain business
combination transactions with "interested stockholders."



AN INVESTMENT IN OUR COMMON STOCK IS RISKY BECAUSE THE PRICE OF OUR STOCK HAS
BEEN VOLATILE AND WE COULD BE DELISTED FROM THE NASDAQ NATIONAL MARKET.



         Our common stock price, like that of many companies in the Internet
industry, has been and may continue to be extremely volatile, and there is a
risk we could be delisted from the Nasdaq National Market. The market price of
our common stock has declined significantly in recent months, and we expect that
it will continue to be subject to significant fluctuations as a result of
variations in our quarterly operating results and volatility in the financial
markets. Although our stock never traded below $1.00, it has traded at the $1.00
level within the last year. If our stock drops below $1.00 per share and
continues to trade at that level for 30 consecutive business days, we may
receive notice from the Nasdaq National Market that we need to comply with the
requirements for continued listing on the Nasdaq National Market within 90
calendar days from such notification or be delisted. If our stock is delisted
from the Nasdaq National Market, an investor could find it more difficult to
dispose of, or to obtain accurate quotations as to the market value of, our
common stock. Additionally, our stock may be subject to "penny stock"
regulations. If our common stock were subject to "penny stock" regulations,
which apply to certain equity securities not traded on the Nasdaq National
Market which have a market price of less than $5.00 per share, subject to
limited exceptions, additional disclosure would be required by broker-dealers in
connection with any trades involving such penny stock.



EXERCISE OF OUTSTANDING OPTIONS AND WARRANTS AND EXERCISE OF OUTSTANDING
CONVERTIBLE NOTES, WILL RESULT IN FURTHER DILUTION.



         The issuance of shares of common stock upon the exercise of our
outstanding options and warrants and the conversion of outstanding convertible
notes, will result in dilution to the


                                       13




interests of our stockholders, and may reduce the trading price and market for
our common stock.



         As of March 31, 2002, we had outstanding options and warrants to
acquire 8,802,116 shares of common stock, 3,688,151 of which are subject to
future vesting. Included in the foregoing are 6,114,620 options which have been
granted under our 1995 Employee Stock Option Plan, our 1999 Non-Qualified Stock
Option Plan and our Non-Employee Director Stock Option Plan, 2,426,469 of which
are immediately exercisable. Also, being registered with this prospectus are
3,635,204 shares which may be acquired upon conversion of the convertible
subordinated notes, and 1,278,270 shares which may be acquired upon exercise of
warrants.



     To the extent that these stock options or warrants are exercised or notes
are converted, the dilution to the interests of our stockholders and you as an
investor will likely occur. Additional options and warrants may be issued in the
future at prices not less than 85% of the fair market value of the underlying
security on the date of grant. Exercise of these options or warrants, conversion
of the notes, or even the potential of their exercise or conversion may have an
adverse effect on the trading price and market for our common stock. The holders
of our options or our warrants are likely to exercise them, and the holders of
our notes are more likely to convert them, at times when the market price of the
common stock exceeds the exercise price of the securities. Accordingly, the
issuance of shares of common stock upon exercise of the options, warrants, or
conversion of the notes will likely result in dilution of the equity represented
by the then outstanding shares of common stock held by other stockholders.
Holders of our options, warrants, or convertible notes can be expected to
exercise or convert them at a time when we would, in all likelihood, be able to
obtain any needed capital on terms which are more favorable to us than the
exercise or conversion terms provided by these options, warrants or convertible
notes.



SUBSTANTIAL SALES OF OUR COMMON STOCK COULD LOWER OUR STOCK PRICE.



Sales of a substantial number of shares of common stock in the public market,
including 3,574,601 shares issued to the former stockholders of MediaSite, Inc.,
which we are in the process of registering, or the perception that these sales
may occur, could adversely affect the market price of the common stock by
potentially introducing a large number of sellers of our common stock into a
market in which the common stock price is already volatile, thus driving the
common stock price down. In addition, the sale of these shares could impair our
ability to raise capital through the sale of additional equity securities.


                                 USE OF PROCEEDS

We will not receive any proceeds from the sale of the Shares by the Selling
Stockholders; all proceeds will go to the Selling Stockholders.

             MARKET FOR COMMON EQUITY, DIVIDEND POLICY, AND RELATED
                              STOCKHOLDER MATTERS

Our common stock was traded on the American Stock Exchange under the symbol

The last traded price on May 24, 2002 for our common stock was $2.30. The
quotations reflect inter-dealer prices, without retail mark-up, markdown or
commission and may not necessarily represent actual transactions.

The Company has not paid any cash dividends and does not intend to pay any cash
dividends in the foreseeable future.

At May 24, 2002 there were 374 common stockholders of record. Many shares are
held by brokers and other institutions on behalf of stockholders and are
therefore not included in these numbers.

                              SELLING STOCKHOLDERS

In January and February 2002, we closed on a $7,125,000 offering of convertible
subordinated debt with several investors (the "Investors"), which were primarily
institutional investors (the "Note Offering"). The promissory notes issued (the
"Notes") bear interest at 10% per annum and

                                       15



mature (if not converted) in monthly installments commencing on December 1,
2002, in the event we raise at least $8,000,000 in additional financing on or
before July 1, 2002 on terms specified in the Notes. In such case, the aggregate
amount of such monthly installments for all the Notes is $330,000 with a final
installment in the aggregate amount of $2,502,000 due on the maturity date of
February 1, 2004. If we do not complete such financing of at least $8,000,000 on
or before July 1, 2002 and otherwise meet the requirements in the Notes, the
Notes mature (if not converted) in monthly installments commencing on August 1,
2002. In such case the aggregate amount of such monthly installments for all the
Notes is $330,000 with a final installment in the aggregate amount of $1,181,000
due on the maturity date of February 1, 2004.

The Notes may be converted into shares of our common stock, in whole or in part,
at any time. The conversion price is $2.45 per share, subject, however to
adjustment. The conversion price will be adjusted in the following
circumstances: (a) in the event we declare a stock dividend or stock split or
combine our shares of common stock; or (b) in the event we issue 500,000 or more
shares (the "New Shares") at a price per share that is lower than both $2.00 per
share and the Investors' then-current conversion price (the lower of the two,
the "Base Price"), in which case the Investors' conversion price will be reduced
to a price equal to the Base Price less 50% of the difference between the Base
Price and the price per share at which the New Shares are issued.

The Investors also received warrants to purchase shares of common stock at a
strike price of $2.94.

We have also issued 105,485 shares to Carnegie Mellon University ("CMU"), which
are not related to the Note Offering. The Shares issued to CMU relate to an
obligation the Company assumed, as part of the MediaSite transaction, for past
due royalties owned by MediaSite.

This Prospectus covers the 3,635,204 shares that may become issuable upon
conversion of the Notes, the 1,163,270 shares to become issuable upon exercise
of the warrants issued to the Investors, 115,000 shares to become issuable upon
exercise of certain other warrants, and 105,485 Shares that were issued to CMU.

The following table sets forth certain information as of May 24, 2002 with
respect to the Selling Stockholders.

Pursuant to the instruments governing the Note Offering, we agreed to file a
registration statement covering the shares of our common stock underlying the
Notes and Warrants, along with an additional 25% of the total shares issuable
upon conversion of the Notes at the current conversion price.

                              PLAN OF DISTRIBUTION

Resales of the Shares by the Selling Stockholders may be made on the Nasdaq
National Market, in the over-the-counter market, in private transactions, or in
a combination of such methods of sale. The Shares will be offered for sale on
terms to be determined when the agreement to sell is made or at the time of
sale, as the case may be. The Selling Stockholders may effect such transactions
by selling some or all of the Shares through broker-dealers who may act solely
as agent and or may acquire Shares as principal or in one or more underwritten
offerings on a firm commitment or best efforts basis. Sales of shares may also
be made pursuant to Rule 144 under the Securities Act of 1933, as amended. To
the extent required under the Securities Act of 1933, as amended, the aggregate
amount of Selling Stockholders' Shares being offered and the terms of the
offering, the names of any such agents, brokers, dealers or underwriters and any
applicable commission with respect to a particular offer will be set forth in an
accompanying prospectus supplement. Any underwriters, dealers, brokers or agents
participating in the distribution of the Shares may receive compensation in the
form of underwriting discounts, concessions, commissions or fees from a Selling
Stockholder and/or purchasers of Selling Stockholders' Shares, for whom they may
act (which compensation as to a particular broker-dealer might be in excess of
customary commissions).

From time to time one or more of the Selling Stockholders may transfer, pledge,
donate or assign its Shares to lenders or others and each of those persons will
be deemed to be a "Selling Stockholder" for purposes of this prospectus. The
number of Shares beneficially owned by those Selling Stockholders who so
transfer, pledge, donate or assign will decrease as and when they take such
actions. The plan of distribution for Selling Stockholders' Shares sold
hereunder will otherwise remain unchanged, except that the transferees, pledges,
donees or other successors will be deemed Selling Stockholders hereunder.

The Selling Stockholders may engage in short sales, including short sales
against the box, puts and calls and other transactions in securities of the
Company or derivatives of Company securities and may sell or deliver Shares in
connection with these trades. A Selling Stockholder may enter into hedging
transactions with broker-dealers and the broker-dealers may engage in short
sales of the Shares in the course of hedging the positions they assume with such
Selling Stockholder, including, without limitation, in connection with
distributions of the Shares by such broker-dealers.


                                       21



The Selling Stockholders may pledge their Shares to their brokers under the
margin provisions of customer agreements. If a Selling Stockholder defaults on a
margin loan, the broker may, from time to time, offer and sell the pledged
Shares.

                                       22

Item 15. Indemnification of Directors and Officers.

Our Articles of Incorporation limit the liability of our directors, in their
capacity as directors but not in their capacity as officers, to the fullest
extent permitted by the Maryland General Corporation Law, or MGCL. Accordingly,
pursuant to the terms of the MGCL as presently in effect, we may indemnify any
director unless it is established that:

- the act or omission of the director was material to the matter giving rise to
the proceeding and was committed in bad faith or was the result of active and
deliberate dishonesty;

- the director actually received an improper personal benefit in money, property
 or services;

- or in the case of any criminal proceeding, the directors had reasonable cause
to believe that the act or omission was unlawful.

In addition, our Bylaws require us to indemnify each person who is or was, a
director, officer, employee or agent of ours to the fullest extent permitted by
the laws of the State of Maryland in the event he is involved in legal
proceedings by reason of the fact that he is or was a director, officer,
employee or agent of ours, or is or was serving at our request as a director,
officer, employee or agent of another corporation, partnership or other
enterprise. We may also advance to such persons expenses incurred in defending a
proceeding to which indemnification might apply, upon terms and conditions, if
any, deemed appropriate by the Board of Directors upon

                                      II-1



receipt of an undertaking by or on behalf of such director or officer to repay
all such advanced amounts if it is ultimately determined that he is not entitled
to be indemnified as authorized by the laws of the State of Maryland. In
addition, we carry director and officer liability insurance

In connection with this offering, certain of the Selling Stockholders have
agreed to indemnify us, our directors and officers and each such person who
controls us, against any and all liability arising from inaccurate information
provided to us by the Selling Stockholders and contained herein.

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 the 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

incorporated by reference in the registration statement;

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

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.

2. Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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

                                      II-3



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.

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

                                   SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this amendment no. 2 to
this registration statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Madison, State of Wisconsin, on May
29, 2002.
