                             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
Corporation, Inc. d/b/a Sonic Foundry Media Services and Sonic Foundry Systems
Group, Inc. d/b/a Sonic Foundry Media Systems, 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 solutions for
the creation, manipulation, and delivery of digital media. Sonic Foundry's
digital audio and video software tools include the award-winning ACID(TM), Sound
Forge(R), Vegas(R) Audio, Vegas(R) Video, VideoFactory(TM), Stream Anywhere(TM),
SIREN(TM) Jukebox, Viscosity(TM), and a variety of compatible music loop
libraries and DirectX Audio Plug-Ins.

     Our Media Services division incorporates our existing technology and a wide
array of audio and video signal processing algorithms, including our unreleased
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 are one of North America's leading suppliers of
technical services to the television program distribution market. These services
include a number of preprocessing algorithms and technologies used for standards
conversions 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 Systems Group, Inc. acquired the assets and
assumed certain liabilities of MediaSite, Inc., a global pioneer in providing
automated rich media publishing, management and access solutions. MediaSite
derived its core technology from a Carnegie Mellon University research effort
funded by leading government agencies and private corporations. MediaSite's
proven technology (hereafter, the "Media Systems technology") provides for the
indexing, searching and retrieving of digital media. In addition, we believe
MediaSite's existing corporate, education and government client base provides
immediate marketing opportunities in the media management area.

                                  RISK FACTORS

Operating History Risks

Our business, financial condition and results of operations have been, and in
the future may be, affected by a variety of factors, including those set forth
below and elsewhere in this prospectus.

We have a history of losses and we may never attain profitability.

     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 September 30, 2001, we had an accumulated
deficit of $148 million. We cannot assure you that we will achieve or maintain
profitability in the future.

We have a limited operating history upon which you can evaluate our business and
our future prospects and our operating results will likely fluctuate
significantly.

     We were incorporated in March 1994 and we have a limited operating history
and limited financial results upon which you can assess our future success. We
have a very limited history of digital media services operations upon which you
can evaluate our digital media services business model and the prospects for
that business. As a result of our limited operating history and the rapidly
changing nature of the markets in which we compete, our quarterly and annual
revenues and operating results are difficult to predict and may fluctuate
significantly from quarter to quarter and from year to year. You should
therefore not rely upon our revenues and our operating results for any one
quarter or year as an indication of our future revenues or operating results.
Our stock price has been and will in all likelihood continue to be extremely
volatile. You should evaluate our chances of financial and operational success
in light of the risks, uncertainties, expenses and difficulties frequently
encountered by growing companies in new and rapidly evolving markets.

Industry Risks

The market for our products and services is relatively new, and we cannot assure
you that the market will develop as we expect.

     Because the market for our products and services is relatively new and
rapidly changing, it is difficult to predict future financial results. Our
research and development and sales and marketing efforts, and business
expenditures are partially based on predictions regarding certain developments
for software products and media services. To the extent that these predictions
prove inaccurate, we may not achieve the level of revenues and operating
expenses that we expect at the time that we expect them and our revenues and
operating expenses may fluctuate.

                                       4



Our markets are highly competitive, and we may not be able to compete
effectively in our business.

     Competition in the markets for digital media software, products and
services is intense. We compete with several companies engaged in the software
and digital media businesses and we expect competition to increase as new
companies enter the market and our current competitors expand their products and
services. This could mean lower prices or reduced demand for our products. Many
of our current and potential competitors have longer operating histories,
greater name recognition, more employees and significantly greater financial,
technical, marketing, public relations and distribution resources than we do,
and we may not be able to successfully compete with them. Any of these
developments would have an adverse effect on our operating results.

Lack of commercial acceptance of, or decreased demand for, complementary
products and technologies developed by third parties may lead to a decreased
demand for our digital media software products and services.

     The success of some of our digital media software products and planned
digital media services depends, in part, upon the commercial acceptance of
products, the Internet and technologies developed by other companies that our
digital media software products and services may complement, including compact
disc recorders, Digital Versatile Disc players and compression technology for
streaming or storing media files. These complementary products help drive the
demand for digital media and if businesses and consumers do not accept these
products, the demand for our products and services may decrease or fail to grow
and our business may suffer.

The success of our business depends, in part, upon strategic relationships that
we have with other companies.

     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 part, 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 multimedia content, provide more secure


                                       5





and easy-to-use electronic commerce solutions and build out the necessary
infrastructure for media delivery. The loss of these strategic relationships,
the inability to find other strategic partners or the failure of our existing
relationships to achieve meaningful positive results could harm our business.

We rely upon a number of distributors to increase our market penetration
domestically and internationally.

     We rely upon 30 distributors in 30 countries to sell and market our digital
media software products internationally. We generally do not have contracts with
these distributors. If these distributors were to cease the sale and marketing
of our products, our international sales may decrease.

     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. Our contracts with
these distributors require us to accept the return of any of our products that
they do not sell and to credit them for the value of these products. Our
contracts also protect certain distributors for the value of 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.

The growth of our business depends upon the increased use of the Internet or
convergence of TV and Internet, for communications, commerce and advertising.

     The growth of our business depends upon the continued growth of the
Internet as a medium for communications. The Internet may not be accepted as a
viable commercial medium for broadcasting digital and multimedia content or
digital media delivery for a number of reasons, including:

     .    potentially inadequate development of the necessary infrastructure to
          accommodate growth in the number of users and Internet traffic;

     .    unavailability of compelling multimedia content; and

     .    delays in the development or adoption of new technological standards
          and protocols or increased governmental regulations, which could
          inhibit the growth and use of the Internet.

     In addition, we believe that other Internet-related issues, including
security of transactions, reliability of data transmission, cost and ease of
use, are not fully resolved and may affect the amount of business that is
conducted over the Internet.

                                       6



Technology Risks

We depend upon access to Microsoft software codes to develop our digital media
software products.

     Quick access to Microsoft's software codes enables us to develop Microsoft
Windows-based software products in a timely manner. Although, in the past,
Microsoft consistently has given us quick access to its software codes,
Microsoft is under no obligation to do so and may refuse us this access in the
future at its discretion. If we do not continue to receive quick access to
Microsoft's software codes, the development of our software products will be
delayed and our business may suffer.

MediaSite's core technology is dependent on licensed technology from Carnegie
Mellon University.

     As part of the MediaSite transaction we assumed a License Agreement
pursuant to which Carnegie Mellon granted MediaSite a worldwide, nonexclusive
license to use certain technology. We are currently in the process of
re-negotiating the License Agreement for an exclusive license in a defined field
of use. This business is dependent on the continuation of the License Agreement
and the availability to us of the technology licensed thereunder. If we are
unsuccessful in obtaining an exclusive license, there is a risk that Carnegie
Mellon could license the technology to another party, including a competitor.
Moreover, if the License Agreement were to terminate, our business, results of
operations and prospects would be adversely affected.

We may not be successful in our attempts to keep pace with rapid technological
change and evolving industry standards.

     The markets for digital media products and digital media services are
characterized by rapidly changing customer requirements, evolving technologies
and industry standards, and frequent new product and service introductions. Our
future success will depend, in part, upon our ability to:

     .    use leading technologies effectively;
     .    enhance our current software products and services;
     .    identify, develop, and market new software products and service
          opportunities; and
     .    influence and respond to emerging industry standards and other
          technological changes.

     We must accomplish these objectives in a timely and cost-effective manner.
We have experienced development delays and cost overruns in our development
efforts in the past and we may encounter such problems in the future. Delays and
cost overruns could affect our ability to respond to technological changes,
evolving industry standards, competitive developments or customer requirements.
Our products also may contain undetected errors that could cause increased
development costs, loss of revenues, adverse publicity, reduced market
acceptance of those products or lawsuits by customers. If we fail to develop
products that achieve widespread market acceptance or that fail to generate
significant revenues to offset development costs, our business and operating
results would suffer. We may not timely and successfully identify, develop and
market new product and service opportunities. If we introduce new products and



                                       7




services, they may not attain broad market acceptance or contribute meaningfully
to our revenues or profitability. Any of these developments would have an
adverse effect on our operating results.

Demand for our digital media software products might decrease or fail to grow if
commercial acceptance of the Microsoft Windows computer operating system
declines.

     Our digital media software products work exclusively on the Microsoft
Windows computer operating system. Some of our competitors offer products for
the Apple Macintosh and other computer operating systems. If the Macintosh
computer operating system, which is popular with many musicians and
videographers, or other competing operating systems, including Linux and Java,
were to become dominant in the marketplace at the expense of the Microsoft
Windows computer operating system, demand for our digital media software
products may decrease or fail to grow. Moreover, if we were unable to adapt our
current digital media software products or develop new digital media software
products in a timely and cost-effective manner to work on these different
operating systems, our business might suffer.

Development of new standards for the electronic delivery of digital media could
significantly affect our growth and the way we do business.

     The onset of competing industry standards for the electronic delivery of
digital media could slow the growth of our business or force us to adjust the
way in which we do business. If standard delivery technology does not achieve
widespread commercial acceptance and we are unable to adapt our digital media
software products accordingly in a timely and cost-effective manner, our
business may suffer.

Our business will suffer if our systems fail or become unavailable.

     A reduction in the performance, reliability and availability of our website
and network infrastructure will harm our ability to market and distribute our
products and services to our users, as well as our reputation and ability to
attract and retain users, customers, advertisers and content providers. Our
systems and operations could be damaged or interrupted by fire, flood, power
loss, telecommunications failure, Internet breakdown, earthquake and similar
events. Our systems are also subject to break-ins, sabotage, intentional acts of
vandalism and similar misconduct. We do not have fully redundant systems or a
formal disaster recovery plan, and we do not carry adequate business
interruption insurance to compensate us for losses that may occur from a system
outage.

     Our electronic commerce and digital distribution activities are managed by
sophisticated software and computer systems. We are in the process of
integrating our enterprise resource planning system, which handles all of our
accounting, operations, sales and information systems at business units acquired
last year. We may encounter delays in adopting this or other systems that we
use. Furthermore, these systems may contain undetected errors that could cause
the systems to fail. Any system error or failure that causes interruption in
availability of products or content or an increase in response time could result
in a loss of potential or existing business services customers. If we suffer
sustained or repeated interruptions, our products, services and website could be
less attractive and our business may suffer.



                                       8




     A sudden and significant increase in traffic on our website could strain
the capacity of the software, hardware and telecommunications systems that we
deploy or use. This could lead to slower response times or system failures. We
depend on Web browsers, ISPs and online service providers to provide Internet
users access to our website. Many of these providers have experienced
significant outages in the past, and could experience outages, delays and other
difficulties due to system failures unrelated to our systems.

Intellectual Property Risks

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. There can be no assurances that we
will ultimately receive issued patents as a result of any of these applications,
or to the extent that we do, that we can always afford to enforce them.

     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, to protect our trade secrets or to determine the
validity and scope of other parties' proprietary rights. From time to time,
other parties' proprietary rights, including patent rights, have come to our
attention and on several occasions we have received notice of claims of
infringement of other parties' proprietary rights, and we may receive such
notices in the future.

Our intellectual property may infringe the rights of others.

     Because we have historically protected our proprietary rights with a
combination of trademark, copyright and trade secret laws, confidentiality
agreements with our employees and third parties and "shrink wrap" licenses and
only recently have begun to apply for patents, our intellectual property may
unintentionally infringe upon the proprietary rights of others. 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


                                       9




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. Any of these events could harm our business.

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.

     Further, the Internet and software industries have experienced substantial
consolidation and a proliferation of strategic transactions. We expect this
consolidation and strategic partnering to continue. Acquisitions or strategic
relationships could harm us in a number of ways. For example:

     .    Our competitors could acquire or form partnerships with companies with
          which we have strategic relationships and discontinue our
          relationship, resulting in the loss of distribution opportunities for
          our products and services or the loss of certain enhancements or
          value-added features to our products and services; or

     .    A party with significant resources and experience could acquire a
          competitor of ours, increasing the ability of the competitor to
          compete with our products and services.

Management Risks

Our business could suffer if we lose the services of key personnel.

     Our success depends in significant part upon a number of key management and
technical employees. The loss of the services of one or more key employees,
particularly Rimas Buinevicius, our Chairman of the Board and Chief Executive
Officer, Monty R. Schmidt, our President, and Curtis Palmer, our Chief
Technology Officer, could seriously impede our success. Although we have
employment agreements with each of these individuals, a state court may
determine not to enforce, or to only partially enforce, these agreements. We do
not have employment agreements with any other of our key employees. Our success
also depends upon our ability to retain highly skilled technical, managerial,
marketing, and customer service personnel. Competition for highly skilled
personnel is intense. Our failure to retain these personnel could adversely
affect our business. In addition, due to the recent significant drop in our
stock price, our ability to attract and retain experienced employees may be
reduced.

                                       10



Risks Associated With Acquisitions

We may pursue acquisitions and investments that could adversely affect our
business.

     If we identify an acquisition candidate, we may not be able to successfully
negotiate or finance the acquisition or integrate the acquired businesses,
products or technologies into our existing business and products. Future
acquisitions could result in potentially dilutive issuances of equity
securities, the incurrence of debt and contingent liabilities, amortization
expenses or write-downs of acquired assets including goodwill and other
intangible assets. Other than the MediaSite transaction, we currently have no
commitments or agreements with respect to any business acquisitions or
investments.

Our acquisition of the assets of MediaSite, Inc. involves risks.

     On October 15, 2001, the Company completed the acquisition of certain
assets, and the assumption of certain liabilities, of MediaSite, Inc. Although
the Company purchased the assets of MediaSite primarily to benefit from its
existing customer relationships and technology, there can be no assurance that
revenues from these relationships will materialize or that competitors won't
develop technologies superior to those acquired. Due to these and other factors,
there can be no assurance that we will obtain benefits from the purchase of the
assets of MediaSite.

     In addition, although the Company purchased only certain scheduled
liabilities of MediaSite, and in fact obtained indemnification from MediaSite
with respect to all unscheduled liabilities, it is possible that an unforeseen
liability may arise and result in a claim against the Company.

Our past and future acquisitions may involve the write down of intangible
assets.

     In the first quarter of 2002, the Company plans to adopt new accounting
rules regarding business combinations and the amortization of intangible assets.
Under the new rules, the Company would cease the amortization of goodwill and
would annually assess its carrying value. See footnote 1, Accounting
Pronouncements for further details.

Risks Associated With The Operation Of Our Business

Our international operations involve risks.

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

     .    Unexpected changes in regulatory requirements.

     .    Export and import restrictions.

     .    Tariffs and trade barriers and limitations on fund transfers.

     .    Longer payment cycles and problems in collecting accounts receivable.

                                       11






     .    Potential adverse tax consequences.

     .    Exchange rate fluctuations.

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

     Any of these factors could harm our business. We do not currently hedge our
foreign currency exposure.

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.

Corporate Governance Risks

Stockholders may be unable to exercise control because our management controls a
large percentage of our stock.

     Our directors, officers and affiliated persons own nearly 40% of our common
stock and have significant influence over stockholder voting matters. If our
directors, officers and affiliated persons act together, they will be able to
influence the composition of our board of directors, and will continue to have
significant influence over our affairs in general.

Provisions of our charter documents and Maryland law could 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."


                                       12





Market Risks

Our stock price has been and may continue to be volatile.

     The trading price of our common stock has been and is likely to continue to
be highly volatile. For example, during the 52-week period ended November 30,
2001, the closing price of our common stock ranged from $1.01 to $5.688 per
share. In addition, the stock market in general, and the market for technology
companies in particular, have experienced extreme price and volume fluctuations
that have often been unrelated or disproportionate to the operating performance
of these companies. These broad market and industry factors may further reduce
our stock price, regardless of our operating performance.

Exercise of outstanding options and warrants will result in further dilution.

     The issuance of shares of common stock upon the exercise of our outstanding
options and warrants will result in dilution to the interests of our
stockholders and you as an investor in the Offering, and may reduce the trading
price and market for our common stock.

     As of September 30, 2001, we had outstanding options and warrants to
acquire 4,019,540 shares of common stock, 1,952,529 of which are subject to
future vesting. Included in the foregoing are 2,974,314 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, 1,021,785 of which
are immediately exercisable.

     To the extent that these stock options or warrants are exercised, 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, 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 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 or our warrants 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 or our warrants
can be expected to exercise 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 terms provided by these options or warrants.

Substantial sales of our common stock could lower our stock price.

     The market price for our common stock could drop as a result of sales of a
large number of our presently outstanding shares, or the perception that these
sales could occur. These factors also could make it more difficult for us to
raise funds through future offerings of our common stock.

                                 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.

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

     At December 19, 2001 there were 371 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

     On October 15, 2001, we purchased substantially all the assets of

                              PLAN OF DISTRIBUTION

     Resales of the Shares by the Selling Stockholders may be made on the Nasdaq
National Market, or in private transactions. 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 sell some or all of the
Shares in transactions involving broker-dealers who may act solely as agent and
or may acquire Shares as principal. Broker-dealers participating in such
transactions as agent may receive commissions from the Selling Stockholders
(and, if they act as agent for the purchaser of such Shares, from such
purchaser), such commissions computed in appropriate cases in accordance with
the applicable rules of NASDAQ, which commissions may be at negotiated rates
where permissible under such rules. Participating broker-dealers may agree with
the Selling Stockholders to sell a specific number of Shares at a stipulated
price per share and, to the extent such broker-dealer is unable to do so acting
as agent, for the Selling Stockholders to purchase as principal any unsold
shares at the price required to fulfill the broker-dealer's commitment to the
Selling Stockholders. Any such sales may be by block trade.

     The Selling Stockholders may also 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. 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.

     In addition, pursuant to a certain Stock Restriction and Registration
Agreement, each of Zero Stage Capital VI Limited Partnership, Saturn Capital,
Inc., and Saturn Partners Limited Partnership (the "Restricted Holders") agreed
that the Shares acquired by them pursuant to the transaction (the "Acquired
Shares") shall not be transferred or disposed of by the Restricted Holders until
3 months following the Closing (which occurred on October 15, 2001). Thereafter
in each succeeding 3 month period, each Restricted Holder may transfer or
dispose of up to 33 1/3% of the Acquired Shares so that the restriction on the
transfer or disposal of the Acquired Shares, only to 66 2/3% of the Acquired
Shares after 3 months from the Closing, only to 33 1/3% of the Acquired Shares
after 6 months from Closing, and to none of the Acquired Shares after 9 months
from Closing.

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

                                      II-1





upon 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.

                             Item 17. Undertakings.

1.   The undersigned registrant hereby undertakes:

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

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

          (ii) To reflect in the prospectus any facts or events arising after
               the effective date of the registration statement (or the most
               recent post-effective amendment thereof) which, individually or
               in the aggregate, represent a fundamental change in the
               information set forth in the registration statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               of securities offered (if the total dollar value of 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 changes in volume and price represent no more than
               a 20 percent 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 the undertakings set forth in paragraphs
               (1)(i) and (1)(ii) above shall not apply if the information
               required to be included in a post-effective amendment by those
               paragraphs is contained in periodic reports filed by the
               registrant pursuant to the Securities Exchange Act of 1934 that
               are incorporated by reference in the registration statement;

     (2)  That, for the purpose of determining any liability under the
          Securities Act of 1933, each such post-effective amendment shall be
          deemed to be a new registration statement relating to the securities
          offered therein, and the offering of such securities at that time
          shall be deemed to be the initial bona fide offering thereof.

     (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

                                      II-3




     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.

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 to Form S-3 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Madison, State of Wisconsin, on December 21, 2001.
