                               PROSPECTUS SUMMARY

   This summary highlights information contained elsewhere in the prospectus.
The summary is not complete and does not contain all the information you should
consider before buying shares in this offering. You should read the entire
prospectus carefully, especially the risks of investing in our common stock
discussed under "Risk Factors." Except where we state otherwise, we present
information in this prospectus assuming (1) the conversion of all outstanding
shares of convertible preferred stock into an aggregate of 13,400,996 shares of
common stock upon the closing of this offering, (2) our common stock will be
sold at $9.00 per share, which is the mid-point of the range shown on the cover
of this prospectus, (3) the underwriters will not exercise their over-allotment
option and (4) the filing of the amended and restated certificate of
incorporation. All share numbers reflect a three for two stock split effected
as a stock dividend on May 26, 1999.

                                    Audible

   We provide premium spoken audio content, such as audio versions of books and
newspapers and radio programs, that is delivered over the Internet and can be
played back on personal computers and hand-held electronic devices. The Audible
service allows consumers to purchase and download content from our Web site,
store it in digital files and play it back on personal computers and electronic
devices. Our Web site, audible.com, contains the largest and most diverse
collection of premium digital spoken audio content available for download on
the Internet, most of which is currently available only through us either
through exclusive arrangements or because, to our knowledge, no one else
currently has digital rights to this content. Visitors to audible.com can
browse through descriptions of audio titles and listen to samples online before
purchasing their selections. A customer can download content immediately or
schedule download for a later time. A customer can also schedule recurring
delivery of many subscription-based periodicals and radio programs. We began
offering our service in October 1997, and thus, we have a limited operating
history with which you can evaluate our business and our future prospects.

   More than 15,000 hours of premium audio content are available at
audible.com, including over 3,000 audio versions of books from publishers such
as Bantam Doubleday Dell Publishing and Random House Publishing, each a
division of Random House, Inc., Dove Audio, Harper Audio, Simon & Schuster
Audio and Time Warner AudioBooks. We also have audio versions of periodicals
such as The New York Times, The Wall Street Journal and The Economist, and
radio programs such as Car Talk, Fresh Air, Marketplace and News From Lake
Wobegon.

   The market for the Audible service results from the increasing usage of the
Internet and the recent introduction of a variety of hand-held electronic
devices that have audio capabilities. Unlike traditional radio broadcasts, the
Audible service offers customers access to content of their choice and the
ability to listen to what they want, when and where they want--whether
commuting, exercising, relaxing or sitting at their personal computers. Unlike
traditional and online bookstores, which are subject to physical inventory
constraints and shipping delays, we provide a selection that is readily
available in a digital format that can be quickly delivered over the Internet.
In addition, we provide customers with lower priced spoken audio content
because we do not incur the manufacturing and distribution costs of audio
content stored on cassette tapes and compact discs.

   Customers use "AudibleReady" devices to access our content. AudibleReady
devices are personal computers and hand-held electronic devices that have a
speaker or an audio output jack and can be enabled to play back our audio
content. Our AudibleManager and AudiblePlayer software enable these devices to
receive and play back Audible content and are available for download from
audible.com at no charge. Recently, several device manufacturers have bundled
the AudibleManager and AudiblePlayer software in the packaging for their
devices. In addition, other device manufacturers plan to adapt their devices to
support the Audible service. The audio output jack of all of these devices can
work with headphones or with a cassette adaptor to enable the content to be
played through a car stereo system.

   In order to measure consumer behavior, to demonstrate to content providers
the viability of secure digital distribution of audio content and to test the
potential of our business model, we designed, created and sold the first
AudibleReady device, the Audible MobilePlayer. We have discontinued the
manufacture of the Audible MobilePlayer to focus our efforts on enabling the
Audible service to be used on a variety of electronic devices. We have
historically derived the majority of our revenue from the sale of the Audible
MobilePlayer, and we expect this revenue to decrease and eventually phase out
as we sell our remaining inventory.In the future, we will depend upon others to
manufacture and promote as "AudibleReady" devices which are capable of playing
our content. The first of these AudibleReady devices only became commercially
available in March 1999. We have agreements with Casio, Compaq, Everex and
Philips to bundle our software with their hand-held electronic devices and
promote our service. These devices, which have a variety of personal computer
and electronic organizer functions including personal information management,
calendar, task list, contact list, mail/messaging and information services, may
be available in limited quantities for the next several quarters. We also have
an agreement with Diamond Multimedia to make the next version of its Rio
Internet Music Player compatible with the Audible service.

   We help publishers, producers, authors, device manufacturers and our Web
site affiliates to create incremental sources of revenue. We provide a new
source of revenue for publishers of newspapers, magazines, journals,
newsletters, professional publications and business information and producers
of radio broadcasts by creating a new market for content that is too timely for
distribution on cassette tape and too specialized for widely broadcast radio
programs. In addition, our service provides companies that distribute or
promote our service and manufacturers of hand-held audio-enabled electronic
devices with a wide selection of content to offer to their customers. We also
derive revenue from other services, including audio production, hosting
services and software development services to integrate our software with the
software and hardware of others.

   We were incorporated in 1995 and commenced commercial operations in October
1997. Our principal executive offices are located at 65 Willowbrook Boulevard,
Wayne, New Jersey 07470, and our telephone number at that location is (973)
890-4070.

                                  RISK FACTORS

   This offering involves a high degree of risk. You should consider carefully
the risks described below and the other information in this prospectus before
deciding to invest in shares of our common stock.

We have a limited operating history with which you can evaluate our business
and our future prospects.

   Our limited operating history and small number of customers makes predicting
our future operating results difficult. From the time we were incorporated in
November 1995 until September 1997, we generated no revenue while we developed
our secure delivery system and a prototype audio playback device, created our
audible.com Web site and established relationships with providers of audio
content. Although we began earning limited revenue in October 1997, we have
continued to focus our resources on refining and enhancing our Web site and our
playback and management software and in expanding our content selections and
developing relationships with manufacturers of hand-held electronics devices.
We have limited history of selling content to users of hand-held electronic
devices manufactured by other parties which only recently became AudibleReady.
We have spent only limited resources on promoting and marketing our service to
consumers. We expect to spend significant resources on expanding our service
and promoting our brand name over the next several quarters. As a result, we
have a limited history of operations and a small number of initial customers
upon which you can evaluate our business model and our prospects.

We have limited revenue, we have a history of losses and we may not be
profitable in the future.

   Our limited revenue and history of losses makes it uncertain when or if we
will become profitable. Our failure to achieve profitability within the time
frame expected by investors may adversely affect our business and the market
price of our common stock. We had total revenue of $376,000 for the year ended
December 31, 1998 and $315,000 for the three months ended March 31, 1999. 65%
of this revenue during 1998 was derived from sales of hardware, which we expect
to decline as we sell our remaining inventory of the Audible MobilePlayer. This
limited revenue makes it difficult to predict our future quarterly results and
our revenue and operating results can vary significantly quarter to quarter.
Our limited revenue will make relatively minor fluctuations in revenue much
more significant on a percentage basis. Our revenue is dependent on the
availability and sales of AudibleReady devices by third-party manufacturers. We
had content and services revenue of only $132,000 for the year ended December
31, 1998 and $58,000 for the three months ended March 31, 1999. We had
operating expenses of $8.4 million for 1998 and $1.9 million for the three
months ended March 31, 1999. Because most of our expenses, such as employee
compensation and rent, are relatively fixed in the short term, we may be unable
to adjust our spending to compensate for unexpected revenue shortfalls.
Accordingly, any significant shortfall in relation to our expectations could
cause significant declines in our operating results. This would likely affect
the market price of our common stock in a manner which may be unrelated to our
long-term operating performance. As of March 31, 1999, we have incurred net
operating losses of approximately $21.2 million since inception, and we expect
to continue to incur significant losses for the foreseeable future.

The market for our service is uncertain and consumers may not be willing to use
the Internet to purchase spoken audio content.

   Downloading of audio content from the Internet is a relatively new method of
distribution and its growth and market acceptance is highly uncertain. Our
success will depend in large part on consumer willingness to purchase and
download spoken audio content over the Internet. Purchasing this content over
the Internet involves changing purchasing habits, and if consumers are not
willing to purchase and download this content over the Internet, our revenue
will be limited and our business will be materially adversely affected. We
believe that acceptance of this method of distribution may be subject to
network capacity constraints, hardware limitations, company computer security
policies, the ability to change user habits and the quality of the audio
content delivered.


                                       7
<PAGE>

We may not be able to license or produce sufficiently compelling audio content
to attract and retain customers and grow our revenue.

   If we are unable to obtain licenses from the creators and publishers of
content to have that content available on our Web site on terms acceptable to
us or if a significant number of content providers terminate their agreements
with us, we would have less content available for our customers, which would
limit our revenue growth and materially adversely affect our financial
performance. Our future success depends upon our ability to accumulate and
deliver premium spoken audio content over the Internet. Although we currently
collaborate with the publishers of periodicals and other branded print
materials to convert their written material into original spoken audio content,
the majority of our content originates from producers of audiobooks, radio
broadcasts, conferences, lectures and other forms of spoken audio content.
Although many of our agreements with content providers are for initial terms of
one to three years, our content providers may choose not to renew their
agreements with us or may terminate their agreements early if we do not fulfill
our contractual obligations. We cannot be certain that our content providers
will enter into new agreements with us on the same or similar terms as those
currently in effect or that additional content providers will enter into
agreements on terms acceptable to us.

Manufacturers of electronic devices may not manufacture, make available or sell
a sufficient number of products suitable for our service, which would limit our
revenue growth.

   If manufacturers of electronic devices do not manufacture, make available or
sell a sufficient number of devices promoted as AudibleReady, or if these
devices do not achieve sufficient market acceptance, we will not be able to
grow revenue and our business will be materially adversely affected. The Compaq
Aero, the first third party device promoted as AudibleReady, only became
commercially available in March 1999 and is available only in limited
quantities. Compaq and Everex have experienced delays in their delivery
schedule of their electronic devices due to parts shortages. Although the
content we sell can be played on personal computers, we believe that a key to
our future success is the ability to playback this content on hand-held
electronic devices. Because we do not intend to continue to manufacture our own
AudibleReady devices, we depend on manufacturers, such as Philips, Casio,
Everex, Compaq and Diamond Multimedia, to develop and sell their own products
and promote them as AudibleReady.

We must establish, maintain and strengthen our brand names, trademarks and
service marks in order to acquire customers and generate revenue.

   If we fail to promote and maintain our brand names, our business, operating
results and financial condition could be materially adversely affected. We
believe that building awareness of the "Audible," "audible.com" and
"AudibleReady" brand names is critical to achieving widespread acceptance of
our service by customers, content providers, device manufacturers and marketing
and distribution companies with which we have business relationships. To
promote our brands, we will need to substantially increase our marketing
expenditures. We have applied for trademark and service mark registrations of
our brand names in the United States. The application for "audible.com" has
been allowed and the applications for "Audible" and "AudibleReady" have
received adverse actions by the Patent and Trademark Office. We are challenging
the adverse actions by filing a request for reconsideration and a notice of
appeal with the Patent and Trademark Office. There can be no assurance that any
of our brand names will be registered as trademarks or that we will effectively
protect the use of these names.

Increasing availability of digital audio technologies may increase competition
and reduce our gross margins, market share and profitability.

   If we do not continue to enhance our service and adapt to new technology, we
will not be able to compete with new and existing distributors of spoken audio,
we will lose market share and our business will be materially adversely
effected. The market for the Audible service is new, rapidly evolving and
intensely competitive. We expect competition to intensify as advances in and
standardization of digital audio distribution,

                                       8
<PAGE>

download, security, management and playback technologies reduce the cost of
starting a digital audio delivery system or a service that gathers audio
content. To remain competitive, we must continue to either license or
internally develop technology that will enhance the features of the Audible
service, our software that manages the downloading and playback of audio
content, our ability to compress audio files for downloading and storage and
our download, security and playback technologies. Increased competition is
likely to result in price reductions, reduced gross margins and loss of market
share, any of which could materially adversely affect our financial
performance.

Our industry is highly competitive and we cannot assure you that we will be
able to compete effectively.

   We face competition in all aspects of our business and we cannot assure you
that we will be able to compete effectively. We compete for consumers of audio
content with other Internet-based audio distributors and distributors of audio
on cassette tape or compact disc. We compete with others for relationships with
manufacturers of electronic devices with audio playback capabilities. The
business of providing content over the Internet is experiencing rapid growth
and is characterized by rapid technological changes, changes in consumer habits
and preferences and the emergence of new and established companies. We compete
with (1) traditional and online retail stores, catalogs, clubs and libraries
that sell, rent or loan audiobooks on cassette tape or compact disc, such as
AudioBook Club, Borders, Barnes & Noble and Amazon.com, (2) Web sites that
offer streaming access to spoken audio content using tools such as the
RealPlayer or Windows Media Player, such as Broadcast.com, (3) other companies
offering services similar to ours, such as Audiohighway.com and Command Audio
and (4) on-line and Internet portal companies such as America Online, Inc.,
Yahoo! Inc., Excite, Inc., Lycos Corporation, Infoseek Corporation and
Microsoft Network, with the potential to offer audio content. Many of these
companies have financial, technological, promotional and other resources that
are much greater than those available to us and could use or adapt their
current technology, or could purchase technology, to provide a service directly
competitive with the Audible service.

Capacity constraints and failures, delays or overloads could interrupt our
service and reduce the attractiveness of our service to existing or potential
customers.

   Any capacity constraints or sustained failure or delay in using our Web site
could reduce the attractiveness of the Audible service to consumers, which
would materially adversely affect our financial performance. Our success
depends on our ability to electronically distribute spoken audio content
through our Web site to a large number of customers efficiently and with few
interruptions or delays. Accordingly, the performance, reliability and
availability of our Web site, our transaction processing systems and our
network infrastructure are critical to our operating results. We have
experienced periodic systems interruptions including planned system
maintenance, hardware and software failures triggered by high traffic levels,
and network failure in the Internet and our Internet service providers. We
believe the complexities of our software and hardware and the potential
instability of the Internet due to rapid user growth mean that periodic
interruptions to our service are likely to continue. A significant increase in
visitors to our Web site or simultaneous download requests could strain the
capacity of our Web site, software, hardware and telecommunications systems,
which could lead to slower response times or system failures. These
interruptions may make it difficult to download audio content from our Web site
in a timely manner.

We could be liable for substantial damages if there is unauthorized duplication
of the content we sell.

   We believe that we are able to license premium audio content in part because
our service has been designed to reduce the risk of unauthorized duplication
and playback of audio files. If these security measures fail, our content may
be vulnerable to unauthorized duplication or playback. If others duplicate the
content we provide without authorization, content providers may terminate their
agreements with us and hold us liable for substantial damages. Although we
maintain general liability insurance, including insurance for errors or
omissions, we cannot assure you that the amount of coverage will be adequate to
compensate us for these losses. Security breaches might also discourage other
content providers from entering into agreements with us. We may be required to
expend substantial money and other resources to protect against the threat of
security breaches or to alleviate problems caused by these breaches.

                                       9

Errors in our proprietary software, including AudibleManager 2.0, could
discourage potential customers and damage our reputation.

   Our proprietary software may contain undetected errors, failures or bugs
which could result in customer dissatisfaction, adverse publicity, loss of
reputation, delay in market acceptance of the AudibleReady format or in legal
claims against us by customers or others. We have in the past discovered
errors, failures and bugs in our software and have experienced customer
dissatisfaction. Version 2.0 of our AudibleManager software is required for
customers to use our service with hand-held electronic devices that use
Microsoft's Windows CE operating system. Version 2.0 has only recently become
commercially available and may contain errors and bugs of which we are unaware.

We do not have a disaster recovery plan or back-up systems, and a disaster
could severely damage our operations.

   If our computer systems are damaged or interrupted by a disaster for an
extended period of time, our business, results of operations and financial
condition would be materially adversely affected. We do not have a disaster
recovery plan in effect and do not have fully redundant systems for the Audible
service at an alternate site. Our operations depend upon our ability to
maintain and protect our computer systems, all of which are located in our
headquarters and at a third party, offsite hosting facility, both of which are
located in northern New Jersey. Although we maintain insurance against general
business interruptions, we cannot assure you that the amount of coverage will
be adequate to compensate us for our losses.

Problems associated with the Internet could discourage use of Internet-based
services like ours.

   If the Internet fails to develop or develops more slowly than we expect as a
commercial medium, our business may also grow more slowly than we anticipate,
if at all. Our success will depend in large part on increasing use of the
Internet. There are critical issues concerning the commercial use of the
Internet which we expect to affect the development of the market for the
Audible service, including:

  .  the secure transmission of customer credit card numbers and other
     confidential information;

  .  the reliability and availability of Internet service providers;

  .  the cost of access to the Internet;

  .  the availability of sufficient network capacity; and

  .  the ability to download audio content through computer security measures
     employed by businesses.

Our Chief Financial Officer only recently became an employee of Audible which
may affect our ability to successfully manage our operations.

   We hired our Chief Financial Officer on June 1, 1999. Accordingly, our
financial team does not have a history of working together. We cannot assure
you that our CFO will be able to work effectively or successfully to manage our
operations. We believe that the successful integration of our CFO with our
management team is critical to our ability to effectively manage our operations
and support our anticipated future growth.

The loss of key employees could jeopardize our growth prospects.

   The loss of the services of any of our executive officers or other key
employees could materially adversely affect our business. Our future success
depends on the continued service and performance of our senior management and
other key personnel, particularly Andrew J. Huffman, our President, and Donald
R. Katz, our Founder and Chairman of the Board. We do not have employment
agreements with any of our executive officers or other key employees.

                                       10
<PAGE>

Our inability to hire new employees may hurt our growth prospects.

   The failure to hire new personnel could damage our ability to grow and
expand our business. Our future success depends on our ability to attract, hire
and retain highly skilled technical, managerial, editorial, marketing and
customer service personnel, and competition for these individuals is intense.
In particular, we have experienced difficulty in hiring software and Web site
developers. Our failure to hire these technical employees could delay
improvements in, and enhancements to, the Audible service.

We have no experience in acquiring companies or technologies and any
acquisitions of this type may disrupt our business or distract our management,
due to difficulties in assimilating acquired personnel and operations.

   We have no experience in acquiring businesses, technologies, services or
products. From time to time, we engage in discussions and negotiations with
companies regarding our acquiring or investing in such companies' businesses,
products, services or technologies. If we acquire or invest in another company,
we could have difficulty in assimilating that company's personnel, operations,
technology and software. In addition, the key personnel of the acquired company
may decide not to work for us. If we make other types of acquisitions, we could
have difficulty in integrating the acquired products, services or technologies
into our operations. These difficulties could disrupt our ongoing business,
distract our management and employees, increase our expenses and adversely
affect our results of operations. Furthermore, we may incur indebtedness or
issue equity securities to pay for any future acquisitions. The issuance of
equity securities would be dilutive to our existing stockholders. As of the
date of this prospectus, we have no agreement to enter into any material
investment or acquisition transaction.

Year 2000 problems could interrupt our service.

   Any Year 2000 compliance problem of ours or our vendors or suppliers could
have a material adverse effect on our ability to service our customers, and on
our business, results of operations and financial condition. Virtually every
computer operation will be affected in some way by the rollover of the two
digit year value to 00. It is unclear whether computer systems will properly
recognize date sensitive information when the year changes to 2000. Systems
that do not properly recognize such information could generate erroneous data
or cause a system to fail. In the most reasonably likely worst case scenario,
the Audible service would be inoperable until the problem is corrected and this
correction could take weeks or months. During this period, we may be unable to
bill our customers or deliver subscriptions to our customers, and the
AudibleManager software may not download audio content at the scheduled
intervals. This type of interruption could damage our reputation and cause
customers to lose interest in the Audible service. We are in the process of
reviewing our systems and working with our software and systems suppliers to be
prepared for the year 2000. We have identified changes that we must make in
order to be prepared for the year 2000. For example, we are in the process of
upgrading to more recent versions of software and database applications that
are certified to be ready for the year 2000. We cannot be sure that all
software and hardware components are or will be Year 2000 compliant. Neither
can we accurately estimate the potential costs of achieving Year 2000
compliance or the effects on our operations if we are unsuccessful.

We may not be able to protect our intellectual property.

   If we fail to protect our intellectual property, we may be exposed to
expensive litigation or risk jeopardizing our competitive position. The steps
we have taken may be inadequate to protect our technology and other
intellectual property. Our competitors may learn or discover our trade secrets
or may independently develop technologies that are substantially equivalent or
superior to ours. We rely on a combination of patents, licenses,
confidentiality agreements and other contracts to establish and protect our
technology and other intellectual property rights. We have one patent and have
filed eight patent applications. We also rely on unpatented trade secrets and
know-how to maintain our competitive position. We may have to litigate to
enforce our intellectual property rights, to protect our trade secrets or to
determine the validity and scope of the proprietary rights of others. This
litigation could result in substantial costs and the diversion of our
management and technical resources which would harm our business.

                                       11
<PAGE>

Other companies may claim that we infringe their copyrights or patents.

   If the Audible service violates the proprietary rights of others, we may be
required to redesign our software, and re-encode the Audible content, or seek
to obtain licenses from others to continue offering the Audible service without
substantial redesign and such efforts may not be successful. We do not conduct
comprehensive patent searches to determine whether our technology infringes
patents held by others. In addition, software development is inherently
uncertain in a rapidly evolving technological environment in which there may be
numerous patent applications pending, many of which are confidential when
filed, with regard to similar technologies. Any claim of infringement could
cause us to incur substantial costs defending against the claim, even if the
claim is invalid, and could distract our management from our business. A party
making a claim could secure a judgment that requires us to pay substantial
damages. A judgment could also include an injunction or other court order that
could prevent us from offering the Audible service. Any of these events could
have a material adverse effect on our business, operating results and financial
condition.

We could be sued for content that we distribute over the Internet.

   A lawsuit based on the content we distribute could be expensive and damaging
to our business. Our service involves delivering spoken audio content to our
customers. As a distributor and publisher of content over the Internet, we may
be liable for copyright, trademark infringement, unlawful duplication,
negligence, defamation, indecency and other claims based on the nature and
content of the materials that we publish or distribute to customers. Although
we generally require that our content providers indemnify us for liability
based on their content and we carry general liability insurance, the indemnity
and the insurance may not cover claims of these types or may not be adequate to
protect us from the full amount of the liability. If we are found liable in
excess of the amount of indemnity or of our insurance coverage, we could be
liable for substantial damages and our reputation and business may suffer.

Future government regulations may increase our cost of doing business on the
Internet.

   Laws and regulations applicable to the Internet covering issues such as user
privacy, pricing and copyrights are becoming more prevalent. The adoption or
modification of laws or regulations relating to the Internet could force us to
modify the Audible service in ways that could adversely affect our business.

We may become subject to sales and other taxes for direct sales over the
Internet.

   Increased tax burden could make our service too expensive to be competitive.
We do not currently collect sales or other similar taxes for download of
content into states other than in New Jersey and Texas. Nevertheless, one or
more local, state or foreign jurisdictions may require that companies located
in other states collect sales taxes when engaging in online commerce in those
states. If we open facilities in other states, our sales into such states may
be taxable. If one or more states or any foreign country successfully asserts
that we should collect sales or other taxes on the sale of our content, the
increased cost to our customers could discourage them from purchasing our
services, which would materially adversely affect our business.

Our executive officers and directors will continue to control approximately 43%
of our common stock.

   After this offering, our executive officers and directors will continue to
control approximately 43% of our common stock and will exercise significant
influence over stockholder voting matters which will limit the influence of our
new stockholders. If our officers and directors 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.

Our contractual obligations, charter and by-laws could discourage an
acquisition of our company that would benefit our stockholders.

   Provisions of our agreement with Microsoft and of our certificate of
incorporation and bylaws 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. These provisions include:

  .  prior to discussing with anyone the sale of our company, we must notify
     Microsoft and Microsoft has a right to negotiate exclusively with us for
     21 days to acquire our company. We are not obligated to accept any offer
     from Microsoft. If we do not reach agreement during this period, we may
     discuss with others the sale of our company;

  .  our board of directors, without stockholder approval, may issue
     preferred stock on terms that they determine. This preferred stock could
     be issued quickly with terms that delay or prevent the change in control
     of our company or make removal of management more difficult. Also, the
     issuance of preferred stock may cause the market price of our common
     stock to decrease;

  .  our board of directors is "staggered" so that only a portion of its
     members are elected each year;

  .  only our board of directors, our chairman of the board, our president or
     stockholders holding a majority of our stock can call special
     stockholder meetings; and

  .  special procedures which must be followed in order for stockholders to
     present proposals at stockholder meetings.

   These provisions could have the effect of delaying, deterring or preventing
a change in the control of our company, could deprive our stockholders of an
opportunity to receive a premium for their common stock as part of a sale of
our company, or may otherwise discourage a potential acquirer from attempting
to obtain control of us, which in turn could materially adversely affect the
market price of our common stock.

There is no prior market for our common stock and the price may decline after
this offering.

   Our common stock has not been traded in the public market before this
offering. We have applied to the Nasdaq National Market to list our common
stock, but we do not know whether active trading in our common stock will
develop or continue after this offering. If active trading does not develop, it
could cause the market price of our common stock to decrease. We will determine
the price you will pay for our common stock through negotiations with the
underwriters. You may not be able to resell your shares at or above the price
you will pay for our common stock.

Future sales of our common stock may lower our stock price.

   If our existing stockholders sell a large number of shares of our common
stock, the market price of the common stock could decline significantly. The
perception in the public market that our existing stockholders might sell
shares of common stock could depress our market price. Immediately after this
offering, approximately 25,003,265 shares of our common stock will be
outstanding. Of these shares, 4,000,000 of the shares included in this offering
will be available for immediate resale in the public market. The remaining 84%,
or 21,003,265 shares of our total outstanding shares, will become available for
resale in the public market as shown on the chart below. All of these remaining
21,003,265 shares are subject to lock-up agreements restricting the sale of
such shares for 180 days from the date of this prospectus. However, the
underwriters can waive this restriction and allow these stockholders to sell
their shares at any time.

   After this offering, the holders of 13,400,996 shares of common stock and
holders of warrants to purchase an aggregate of 1,575,001 shares of our common
stock and warrants to purchase 55,261 shares of our preferred stock, which
preferred stock warrants will be exercisable for 82,891 shares of common stock
following this offering, will have the right to require us to register the sale
of their shares, subject to limitations and the lock-up agreements with the
underwriters. These holders also have the right to require us to include their
shares in any future public offerings of our equity securities. Within
approximately 180 days after this offering, we intend to file one or more
registration statements under the Securities Act to register 9,000,000 shares
of common stock reserved for issuance under our stock plan, subject to the
lock-up agreements.

Investors will experience immediate and substantial dilution of $7.39 in the
book value of their investment.

   If you purchase shares of our common stock in this offering, you will
experience immediate dilution of $7.39 per share because the price that you pay
will be substantially greater than the net tangible book value per share of the
shares you acquire. This dilution is due in large part to the fact that our
earlier investors paid substantially less than the public offering price when
they purchased their shares. You will experience additional dilution upon the
exercise of stock options or warrants to purchase common stock.

We will have broad discretion in using the proceeds from this offering.

   We have not identified specific uses for $21.5 million of the proceeds from
this offering, and we will have broad discretion in how we use them independent
of what the stockholders might believe is best for our company. We are unable
to determine how much of the proceeds will be used for any identified purpose
because circumstances regarding our planned uses of the proceeds may change.
You will not have the opportunity to evaluate the economic, financial or other
information on which we base our decisions on how to use the proceeds.

<PAGE>

                                USE OF PROCEEDS

   We estimate that we will receive approximately $32.5 million in net proceeds
from the offering (approximately $37.5 million if the underwriters' exercise
their over-allotment in full), based upon an assumed initial public offering
price of $9.00 per share, after deducting estimated underwriting discounts and
commissions and offering expenses.

   We expect to use the net proceeds from this offering as follows:

  .  approximately $6.0 million for marketing activities, including the
     promotion of our service and brand name;

  .  approximately $5.0 million for the acquisition and production of new
     audio content, and extending existing content licensing arrangements;
     and

  .  approximately $21.5 million for working capital and general corporate
     purposes, including obtaining and extending technology licensing
     arrangements, increasing personnel, increasing production and server
     system capacities, and to finance operating losses that we expect to
     incur as we expand our customer base. A portion of the proceeds may also
     be used for acquisition of companies or technologies.

However, changing business conditions and unforeseen circumstances could cause
the actual amounts used for these purposes to vary from these estimates.

   Pending such uses, we will invest the proceeds of this offering in short-
term, interest-bearing, investment-grade securities, certificates of deposit or
direct or guaranteed obligations of the United States.

                                DIVIDEND POLICY

   We have never declared or paid any cash dividends on our capital stock. We
currently expect to retain future earnings, if any, for use in the operation
and expansion of our business and do not anticipate paying any cash dividends
in the foreseeable future.

     public offering price of $9.00 per share in this offering, after
     deducting estimated underwriting discounts and commissions and estimated
     offering expenses.

                                    DILUTION

   Our pro forma net tangible book value at March 31, 1999 was $7,769,185 or
$0.37 per common share. Pro forma net tangible book value is the amount of
total tangible assets less total liabilities. Pro forma net tangible book value
per common share is net tangible book value divided by the pro forma number of
shares of common stock outstanding as of March 31, 1999. Net pro forma as
adjusted tangible book value per common share is determined by dividing our net
tangible book value as adjusted by the number of shares of our common stock
outstanding after giving effect to this offering. Assuming no changes in our
net tangible book value, other than to give effect to the sale of the common
stock offered by this prospectus at an assumed initial public offering price of
$9.00 per share, the mid-point of the range on the cover of this prospectus,
and the application of the net offering proceeds as described under "Use of
Proceeds," our pro forma as adjusted net tangible book value at March 31, 1999
would have been $40,249,185, or $1.61 per common share.

   This represents an immediate increase in pro forma net tangible book value
of $1.24 per common share to existing stockholders, and an immediate dilution
in pro forma net tangible book value of $7.39 per common share to new investors
purchasing our common stock in this offering. The following table illustrates
this per share dilution.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   The following discussion and analysis of our financial condition and results
of operations should be read in conjunction with "Selected Historical Financial
Data" and our financial statements and notes thereto appearing elsewhere in
this prospectus. This discussion and analysis contains forward-looking
statements that involve risks and uncertainties. Our actual results may differ
materially from those anticipated in these forward-looking statements as a
result of a number of factors, including, but not limited to, those set forth
under "Risk Factors" and elsewhere in this prospectus.

   This prospectus contains forward-looking statements and information relating
to our company. We generally identify forward-looking statements in this
prospectus using words like "believe," "intend," "will," "expect," "may,"
"should," "plan," "project," "contemplate," "anticipate," "seek" or similar
terminology. These statements are based on our beliefs as well as assumptions
we made using information currently available to us. Because these statements
reflect our current views concerning future events, these statements involve
risks, uncertainties and assumptions. Actual results may differ significantly
from the results discussed in these forward-looking statements.

Overview

   We provide Internet-delivered premium spoken audio content for playback on
personal computers and hand-held electronic devices. We have the largest and
most diverse collection of premium digital spoken audio content available for
purchase and download from the Internet, most of which is currently available
only through us. We were incorporated in 1995, commenced commercial operations
in October 1997, and through March 31, 1999, we were in the development stage
for financial reporting purposes. Subsequent to March 31, 1999, we
substantially completed our development efforts in establishing our business
and accordingly no longer consider ourselves a development stage company.

   In order to test consumer behavior, demonstrate to content providers the
viability of digital distribution of audio content and test our business model,
we designed, created and sold limited numbers of our own Internet-enabled
mobile audio playback device, the Audible MobilePlayer. We have historically
derived the majority of our revenue through the sale of this device. Sales of
the MobilePlayer accounted for 95% of our revenue in 1997, 65% of our revenue
in 1998 and 18% of our revenue for the three months ended March 31, 1999. We
expect this revenue to decrease and eventually phase out because we
discontinued the production of the player in April 1999 and expect to sell the
majority of our remaining inventory by the end of 1999. Our primary focus is
the aggregation and delivery of digital spoken audio content, and, in the
future, we will depend upon computer and consumer electronics companies to
manufacture and sell devices that are promoted as AudibleReady. The first of
these devices became commercially available in March 1999. Revenue from the
sale of audio content through our Web site has increased in each of the last
four quarters. We expect that trend to continue and, over the next several
quarters, sales of audio content will increase and eventually account for the
majority of our revenue. As of March 31, 1999, more than 3,900 customers had
purchased content from our Web site.

   Although we have experienced revenue growth in our content sales in recent
periods, there can be no assurance that such growth rates are sustainable, and
therefore such growth rates should not be considered indicative of future
operating results. There can also be no assurance that we will be able to
continue to increase our revenue or attain profitability or, if increases in
revenue and profitability are achieved, that they can be sustained. We believe
that period-to-period comparisons of our historical operating results are not
meaningful and should not be relied upon as an indication of future
performance.

   We recognize revenue from content sales in the period when content is
downloaded. Typically, we pay our content providers a 12% royalty based upon
net sales of the content downloaded by our customers. Some of our content
agreements require us to make advance royalty payments for minimum guarantees
which are amortized on a straight-line basis over the term of the agreement or
are expensed as royalties are earned, whichever is sooner.

   We recognize revenue from subscriptions pro rata over the subscription term.
Royalty expense on subscriptions is currently accrued on the full subscription
price in the month the subscription is purchased. We

                                       20
<PAGE>

plan to implement a financial reporting system that will allow us to pro rate
the accrual on the subscription royalty over the term of the subscription.

   We recognize revenue from sales of the Audible MobilePlayer upon shipment.
We recognize revenue from audio production and hosting services which we
provide to corporations as the services are performed.

   In November 1998, we entered into an agreement with Microsoft, one of our
stockholders, to integrate some of our products, grant various rights and
licenses and provide for Microsoft to be paid future royalties for content
distributed as a result of the customized software developed under the
agreement. Microsoft committed a minimum of $2.0 million in payments to us over
the course of the five-year term of the agreement to integrate products and
acquire various rights and licenses. $200,000 of these payments related to
technology integration services which have been performed and therefore the
related revenue was recognized as other revenue in the quarter ended March 31,
1999. $1.5 million of these payments relates to a fee paid by Microsoft for the
right to distribute software on electronic books that will enable electronic
book customers to purchase and access Audible content in conjunction with text
which we do not provide. This payment was advanced in the three months ended
December 31, 1998, and will be recognized as revenue on a straight line basis
over the initial term of the agreement which runs through the second quarter of
2001, beginning in the quarter ended June 30, 1999. Also under the agreement,
we will deliver a license for technology rights in exchange for $250,000, for
which revenue will be recognized upon acceptance, and we will deliver 300
Audible MobilePlayers in exchange for $50,000, for which revenue will be
recognized when shipped. In addition, Microsoft will be paid a royalty on
content licensed and distributed by Audible to each end user that accesses its
content using the developed software. Microsoft has options under the agreement
to acquire additional rights and licenses and extend the term of the agreement
for additional financial consideration.

   We are party to several joint marketing agreements, including ones with
device manufacturers such as Casio, Compaq, Diamond Multimedia, Everex and
Philips. Under these agreements, our device manufacturers may receive a portion
of the revenue generated over a specified period of time by each new Audible
customer referred by them through the purchase of a new device. For example, a
purchaser of Compaq's hand-held electronic device known as Aero will be able to
use the device and our AudibleManager software to access audible.com and
download content. Compaq will receive a percentage of the revenue related to
content downloaded by this purchaser. These revenue sharing arrangements
typically last one or two years from the date the device user becomes an
Audible customer.

   We have only a limited operating history with which to evaluate our business
and prospects. Our limited operating history and emerging nature of the market
for Internet-delivered audio content makes predicting our future operating
results difficult. In addition, our prospects must be considered in light of
the risks and uncertainties encountered by companies in the early stages of
development in new and rapidly evolving markets, specifically the rapidly
evolving market for delivery of audio content over the Internet. These risks
include our ability to:

  .  acquire and retain customers;
  .  build awareness and acceptance of audible.com, the AudibleReady format
     and AudibleReady devices;
  .  extend existing and acquire new content provider relationships; and
  .  manage growth to stay competitive and fulfill customer demand.

If we fail to manage these risks successfully, it would materially adversely
affect our financial performance.

   As of March 31, 1999, we had not entered into any derivative financial
instruments, other financial instruments or derivative commodity investments
that expose us to material market risk. We currently do not and do not plan to
engage in derivative instruments or hedging activities.

   We have incurred significant losses since inception, and as of March 31,
1999, we had an accumulated deficit of approximately $21.2 million. We believe
that our success will depend largely on our ability to extend our leadership
position as a provider of premium digital spoken audio content over the
Internet. Accordingly, we plan to invest heavily in sales and marketing and
content acquisition and production over the next several quarters, to add
additional personnel and to make capital expenditures to upgrade our systems
capacity.

Three months ended March 31, 1999 and 1998

   Total revenue. Total revenue for the three months ended March 31, 1999, was
$315,000, as compared to $120,000 for the three months ended March 31, 1998, an
increase of $195,000, or 162%.

   Content and services. Content and services revenue for the three months
ended March 31, 1999, was $58,000, as compared to $30,000 for the three months
ended March 31, 1998, an increase of $28,000, or 92%. Content and services
revenue increased primarily as a result of our increased customer base.

   Hardware. Hardware revenue for the three months ended March 31, 1999, was
$57,000, as compared to $90,000 for the three months ended March 31, 1998, a
decrease of $33,000, or 37%. Hardware revenue decreased as we de-emphasize the
sale of the Audible MobilePlayer in anticipation of the adoption of mobile
devices produced by other manufacturers. Hardware revenue also decreased due to
the sale of the MobilePlayer at a reduced introductory price with a minimum
monthly content purchase commitment.

   Other. Other revenue for the three months ended March 31, 1999, was
$200,000, as compared to no other revenue for the three months ended March 31,
1998. Other revenue consisted of services provided to create an AudibleReady
software player for Microsoft's Windows CE product.

 Operating expenses.

   Cost of content and services revenue. Cost of content and services revenue
consists primarily of amortized minimum guarantees and royalties earned in
excess of the amortized minimum guarantees. These amortized amounts consist of
advance royalties paid or guaranteed to be paid to our content providers
regardless of the amount of content used by us during that period. These
amounts are amortized on a straight-line basis over the terms of the content
agreements or are expensed as royalties when earned, whichever is sooner. Cost
of content and services revenue was $152,000, or 262% of content and services
revenue, for the three months ended March 31, 1999, as compared to $75,000, or
250% of content and services revenue, for the three months ended March 31,
1998. This increase was primarily due to the acquisition of additional content
licenses and resulting amortization of new content agreement guarantees. Earned
royalties were $11,000, or 19% of content and services revenue, for the three
months ended March 31, 1999, and $4,000, or 13% of content and services
revenue, for the three months ended March 31, 1998. Amortization of minimum
guarantees was $141,000 for the three months ended March 31, 1999, and $72,000
for the three months ended March 31, 1998.

   Cost of hardware revenue. Cost of hardware revenue consists primarily of the
cost of manufacturing the Audible MobilePlayers sold, write-down of
MobilePlayers in inventory to their estimated net realizable value prior to
September 30, 1998, packaging and collateral material, and fulfillment and
shipping costs. Cost of hardware revenue was $63,000, or 110% of hardware
revenue, for the three months ended March 31, 1999, as compared to $255,000, or
283% of hardware revenue, for the three months ended March 31, 1998. This
decrease was primarily due to write-downs of inventory units to their net
realizable value.

   Production expenses. Production expenses consist primarily of personnel and
outsourced costs to support our infrastructure and systems including our Web
site, internal data communications, audio production activities and acquisition
of content. Production expenses were $495,000 for the three months ended March
31, 1999, as compared to $486,000 for the three months ended March 31, 1998, an
increase of $9,000, or 2%. This increase was primarily due to increased audio
production.

   Research and development. Research and development expenses are expensed as
incurred and consist of costs incurred in the development of our Web site and
AudibleManager, the software that enables customers to download and manage our
audio content. In 1998, research and development costs consisted primarily of
costs incurred under agreements for the continued design and manufacture of the
Audible MobilePlayer. Research and development costs were $320,000 for the
three months ended March 31, 1999, as compared to $389,000 for the three months
ended March 31, 1998, a decrease of $69,000, or 18%. This decrease was
primarily due to reduced costs resulting from discontinuing the design of the
Audible MobilePlayer, offset by increased personnel and outsourced costs in the
development of new AudibleReady formats.

   Sales and marketing. Sales and marketing expenses consist primarily of
personnel costs, advertising, travel, promotional materials, tradeshows and
public relations. Sales and marketing expenses were $396,000 for the three
months ended March 31, 1999, as compared to $272,000 for the three months ended
March 31, 1998, an increase of $124,000, or 46%. This increase was primarily
due to an increase in personnel and advertising costs.

   General and administrative. General and administrative expense consists
primarily of administrative and business development personnel costs, legal and
accounting fees, recruiting costs and facility costs. General and
administrative expense was $431,000 for the three months ended March 31, 1999,
as compared to $481,000 for the three months ended March 31, 1998, a decrease
of $50,000, or 10%. This decrease was primarily due to reduced administrative
personnel costs as a result of lower headcount.

   Interest income. Interest income, consists primarily of interest income
earned on our cash and cash equivalents balances. Interest income was $83,000
for the three months ended March 31, 1999, as compared to $11,000 for the three
months ended March 31, 1998, an increase of $72,000. This increase was
primarily due to additional interest income resulting from a higher average
cash and cash equivalent balance during the three months ended March 31, 1999.

                                       23
<PAGE>

   Interest expense. Interest expense consists of interest paid in connection
with our capital equipment lease line. Interest expense was $15,000 for the
three months ended March 31, 1999, as compared to $17,000 for the three months
ended March 31, 1998, a decrease of $2,000. This decrease was primarily due to
the lower principal balance on our capital equipment lease line.

Years ended December 31, 1998 and 1997

   Total revenue. Total revenue for the year ended December 31, 1998, was
$376,000, as compared to $60,000 for the year ended December 31, 1997, an
increase of $316,000, or 524%.

   Content and services. Content and services revenue for the year ended
December 31, 1998, was $132,000, as compared to $3,000 for the year ended
December 31, 1997, an increase of $129,000. Content and services revenue
increased as a result of our increased customer base.

   Hardware. Hardware revenue for the year ended December 31, 1998, was
$244,000, as compared to $57,000 for the year ended December 31, 1997, an
increase of $186,000, or 324%. Hardware revenue increased as the number of
MobilePlayers sold increased which was partly offset by a reduction in their
price.

 Operating expenses.

   Cost of content and services revenue. Cost of content sales and services
revenue was $372,000, or 281% of content and services revenue, for the year
ended December 31, 1998, as compared to $78,000, for the year ended December
31, 1997. This increase was primarily due to the acquisition of additional
content and resulting amortization of minimum guarantees of new content
contract. Earned royalties were $24,000, or 18% of content and services
revenue, for the year ended December 31, 1998, and $2,000, or 82% of content
and services revenue, for the year ended December 31, 1997. Amortization of
contract guarantees was $349,000 for the year ended December 31, 1998, and
$76,000 for the year ended December 31, 1997.

   Cost of hardware revenue. Cost of hardware revenue was $556,000, or 228% of
hardware revenue, for the year ended December 31, 1998, as compared to $252,000
for the year ended December 31, 1997, an increase of $304,000, or 120%. This
increase was primarily due to the increase in the total number of MobilePlayers
sold.

   Production expenses. Production expenses were $1.6 million for the year
ended December 31, 1998, as compared to $2.0 million for the year ended
December 31, 1997, a decrease of $343,000, or 17%. This decrease was primarily
due to the reduction of personnel and outsourced costs following the completion
and launch of our Web site and the production of our initial audio content in
1997.

   Research and development. Research and development expenses were $1.6
million for the year ended December 31, 1998, as compared to $2.7 million for
the year ended December 31, 1997, a decrease of $1.0 million, or 39%. This
decrease was primarily due to completion of the development in 1997 of the
Audible MobilePlayer, the completion of our Web site and of Version 1.0 of the
AudibleManager software.

   Write-down related to hardware business. Write-down related to hardware
business was $952,000 for the year ended December 31, 1998. This charge
comprises a reduction of $370,000 in the carrying value of the remaining
inventory of Audible MobilePlayers, the impairment loss of $181,000 on
MobilePlayer molds and manufacturing equipment and a charge of $401,000 to
satisfy any remaining purchase commitments under the agreement.

   Sales and marketing. Sales and marketing expenses were $1.5 million for the
year ended December 31, 1998, as compared to $1.2 million for the year ended
December 31, 1997, an increase of $226,000, or 18%. This increase was primarily
due to increased personnel and advertising costs.

   General and administrative. General and administrative expense was $1.8
million for the year ended December 31, 1998, as compared to $1.9 million for
the year ended December 31, 1997, a decrease of $83,000, or 4%. This decrease
was primarily due to a reduction in administrative personnel costs.

   Interest income. Interest income was $53,000 for the year ended December 31,
1998, as compared to $151,000 for the year ended December 31, 1997, a decrease
of $98,000, or 65%. This decrease was primarily due to a lower average cash and
cash equivalent balance during the year ended December 31, 1998.

   Interest expense. Interest expense was $115,000 for the year ended December
31, 1998, as compared to $107,000 for the year ended December 31, 1997, an
increase of $8,000, or 7%. This increase was primarily due to additional
interest expense resulting from increased obligations under our capital
equipment lease line during 1998.

Years ended December 31, 1997 and 1996

   Total revenue. Total revenue for the year ended December 31, 1997 was
$60,000 primarily from the sale of Audible MobilePlayers, and we had no revenue
for the year ended December 31, 1996.

 Operating expenses.

   Production expenses. Production expenses were $2.0 million for the year
ended December 31, 1997, as compared to $684,000 for the year ended December
31, 1996, an increase of $1.3 million, or 190%. This increase was primarily due
to increased personnel in connection with audio production, content acquisition
and Web site development and outsourced costs in preparation for the launch of
the Audible service in late 1997.

   Research and development. Research and development expenses were $2.7
million for the year ended December 31, 1997, as compared to $1.8 million for
the year ended December 31, 1996, an increase of $862,000, or 48%. This
increase was primarily due to increased personnel in connection with the
development of the Audible MobilePlayers and outsourced development costs in
preparation for the launch of the Audible service in late 1997.

   Sales and marketing. Sales and marketing expenses were $1.2 million for the
year ended December 31, 1997, as compared to $256,000 for the year ended
December 31, 1996, an increase of $971,000, or 379%. This increase was
primarily due to increased personnel as we commenced our sales and marketing
activities and other marketing costs in preparation for the launch of the
Audible service in late 1997.

   General and administrative. General and administrative expense was $1.9
million for the year ended December 31, 1997, as compared to $787,000 for the
year ended December 31, 1996, an increase of $1.1 million or 144%. This
increase was primarily due to increased personnel and facility costs in
preparation for the launch of the Audible service in late 1997.

   Interest income. Interest income was $151,000 for the year ended December
31, 1997, as compared to $28,000 for the year ended December 31, 1996, an
increase of $123,000, or 435%. This increase was primarily due to the interest
income resulting from a higher average cash and cash equivalent balance during
1997.

   Interest expense. Interest expense was $107,000 for the year ended December
31, 1997, as compared to $750 for the year ended December 31, 1996. This
increase was primarily due to additional interest expense resulting from the
origination of obligations under our lease line which was used to purchase
capital equipment during 1997.

Factors Affecting Operating Results

   Our operating results have varied on a quarterly basis during our short
operating history and may fluctuate significantly in the future as a result of
a variety of factors, many of which are outside of our control. Factors that
may affect our quarterly operating results include but are not limited to: (1)
the demand for the Audible service; (2) the availability of premium audio
content; (3) sales and consumer usage of AudibleReady devices; (4) the
introduction of new products or services by a competitor; (5) the cost and
availability of acquiring sufficient web site capacity to meet our customers'
needs; (6) technical difficulties with our computer system or the Internet or
system downtime; (7) the cost of acquiring audio content; (8) the amount and
timing

                                       25
<PAGE>

of capital expenditures and other costs relating to the expansion of our
operations; and (9) general economic conditions and economic conditions
specific to electronic commerce and online media. In the past, we experienced
fluctuations in demand for the Audible service based on the level of marketing
expenditures, the occurrence of external publicity and the quality of our
software and Website. Any one of these factors could cause our revenue and
operating results to vary significantly in the future. In addition, as a
strategic response to changes in the competitive environment, we may from time
to time make pricing, service or marketing decisions or acquisitions that could
cause significant declines in our quarterly operating revenue.

   Our limited operating history and the emerging nature of our market make
prediction of future revenue difficult. We have no assurance that we will be
able to predict our future revenue accurately. Because we have a number of
fixed expenses, we may be unable to adjust our spending in a timely manner to
compensate for unexpected revenue shortfalls. Accordingly, any significant
shortfall in relation to our expectations could cause significant declines in
our operating results. We believe that our quarterly revenue, expenses and
operating results could vary significantly in the future, and that period-to-
period comparisons should not be relied upon as indications of future
performance. Due to the foregoing factors, it is likely that in some future
quarters our operating results will fall below the expectations of securities
analysts and investors, which could have a material adverse effect on the
trading price of our common stock.

Liquidity and Capital Resources

   From inception, we have financed our operations through private sales of our
redeemable convertible preferred stock and warrants. Net proceeds from
inception to March 31, 1999 are approximately $28.7 million. At March 31, 1999,
our principal source of liquidity was approximately $9.6 million of cash and
cash equivalents. At March 31, 1999, our principal commitments consisted of
obligations under our capital lease line, which allows us to purchase up to
$1.8 million of equipment, operating lease commitments, contractual commitments
with content providers and revenue sharing commitments pursuant to agreements
with device manufacturers. At March 31, 1999, we had leased approximately $1.2
million in equipment on this line and had an outstanding balance of
approximately $659,000. Our cash and cash equivalents and capital lease line
will support our liquidity needs in the short-term.

   Net cash used in operating activities was $2.6 million for 1996, $8.6
million for 1997, $5.0 million for 1998 and $1.7 million for the three months
ended March 31, 1999. Net cash used in all such periods was primarily
attributable to increases in inventory, offset in part by increases in
advances, accounts payable and accrued liabilities.

   Net cash used in investing activities was $56,000 for 1996, $276,000 for
1997, $4,000 for 1998 and $97,000 for the three months ended March 31, 1999.
Net cash used in investing activities in all such periods were primarily
related to purchases of property and equipment and during 1997, we invested
$100,000 in an interest bearing note issued to a stockholder.

   Net cash provided by financing activities was $3.0 million for 1996, $8.8
million for 1997, $14.9 million for 1998 and $908,000 for the three months
ended March 31, 1999. During 1998, we had a $1.0 million bank agreement to
provide letters of credit which expired in April 1999 and under which we did
not draw any amounts. During 1997, we had a $500,000 bank line of credit
agreement under which we drew the full amount. This line expired in December
31, 1997 and prior to such time, the balance had been paid in full. Net cash
provided by financing activities resulted primarily from the issuance of our
redeemable convertible preferred stock offset by capital lease payments.

   As of December 31, 1998, we had available net operating loss carryforwards
totaling $10.7 million, which expire beginning in 2010. The Tax Reform Act of
1986 imposes limitations on our use of net operating loss carryforwards because
certain stock ownership changes have occurred.

   We believe the net proceeds from this offering, together with our current
cash and cash equivalents, will be sufficient to meet our anticipated cash
requirements for at least the next 12 months. We plan to use the

                                       26
<PAGE>

proceeds of this offering to increase our sales and marketing efforts, acquire
new content, extend our arrangements with our current content providers, add
additional personnel and make capital expenditures to upgrade our systems
capacity. Our current plans provide that approximately $21.5 million of the
proceeds from this offering will be available for use by us at the discretion
of our management. In the future, we may need to raise additional funds
through public or private financing, or other arrangements. We have no
assurance that such additional financing, if needed, will be available on
terms favorable to us or to our stockholders.

Year 2000 Readiness

 General

   Many of the world's computer systems (including those in non-information
technology equipment and systems) currently record years in a two-digit
format. If not addressed, these computer systems will be unable to properly
interpret dates beyond the year 1999, which could lead to business
disruptions. The potential costs and uncertainties associated with the Year
2000 issue will depend on a number of factors, including software, hardware
and the nature of the industry in which a company operates.

   We have instituted a company-wide project for addressing the Year 2000
issue. We are integrating this project with a project involving the upgrade of
our Web site. The Year 2000 project is divided into two parts--System
Infrastructure Upgrades and Vendor Compliance. These sections are discussed
separately below. The project is on schedule for completion by the end of the
third quarter 1999.

 System Infrastructure Upgrades

   We intend to achieve Year 2000 compliance for our internal systems by the
end of the third quarter of 1999. Our limited number of personal computers and
application systems are anticipated to facilitate rapid progress toward full
Year 2000 compliance. We are in the process of upgrading to more recent
versions of operating systems software that are certified to be ready for the
Year 2000.

   We intend to continue to work to achieve Year 2000 compliance for our
systems using a methodology that incorporates the following steps:

     .  update the inventory of computer hardware, software and miscellaneous
  network components,

     .  evaluate application development environment compliance,

     .  conduct overall assessment of systems infrastructure compliance,

     .  complete business risk analysis,

     .  take remedial actions (upgrade, repair, replace, retire or retain),
  and

     .  develop appropriate contingency plans, and develop and implement
  regimes to test Year 2000 compliance for mission-critical systems.

   We are at the remedial action stage, and we currently anticipate completion
of this process by the end of the third quarter 1999 in order to avoid Year
2000 impact on our systems.

 Vendor Compliance

   This section includes the process of identifying and prioritizing critical
suppliers of technology and communicating with them about their plans and
progress in addressing the Year 2000 problem. This process will include not
only manufacturers with which we have agreements, but also providers of
insurance, financial and other services.

   Our vendor compliance program will include the following steps:

     .  catalog and classify all vendors,

     .  on-site review and testing of out-sourced services or systems,

                                      27
<PAGE>

     .  review responses from vendors to determine the level of compliance,

     .  determine the timing, method and cost of vendor solutions,

     .  assess vendor Year 2000 compliance and business risks, and

     .  develop remedial actions or contingency plans, as necessary.
   We are at the remedial action stage of this program. Achievement of vendor
Year 2000 compliance is anticipated to be an on-going effort during 1999. The
current target to achieve compliance or complete contingency plans is by the
end of the third quarter 1999.

 Costs

   The estimated cost to compete the Year 2000 compliance project is
approximately $100,000, not including software and hardware upgrades already
budgeted as part of our next generation Web site. These costs are expected to
be incurred throughout 1999. These costs will be incurred primarily for the use
of outside consultants, setting up Year 2000 testing environments and the
replacement of existing software and hardware.

 Risks

   The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, our Web site and some of our normal business
activities or operations. Such failures could materially and adversely affect
our business, financial condition and results of operations. Moreover, even if
we successfully remediate our Year 2000 issues, we can be materially and
adversely affected by failures of our vendors to remediate their own Year 2000
issues. The failure of our vendors with which we have financial or operational
relationships to remediate their computer and non-information technology
systems issues in a timely manner could result in a material financial risk to
us. Due to the general uncertainty inherent in the Year 2000 problem, resulting
in part from the uncertainty of the Year 2000 readiness of vendors, we are
unable to determine at this time whether the consequences of Year 2000 failures
will have a material impact on our business, financial condition and results of
operations. Accordingly, we may experience business interruption or shutdown,
financial loss, damage to our reputation and legal liability. We believe that,
with the implementation of new business systems and completion of the project
as scheduled, the possibility of significant interruptions of normal operations
should be reduced.

   Our expectations about future costs and the timely completion of our Year
2000 project are subject to uncertainties that could cause actual results to
differ materially from what has been discussed above. Factors that could
influence the amount of future costs and the effective timing of remediation
efforts include our success in identifying computer programs and non-
information technology systems that contain two-digit year codes, the nature
and amount of programming and testing required to upgrade or replace each of
the affected programs and systems, the rate and magnitude of related labor and
consulting costs, and the success of our vendors in addressing the Year 2000
issue.

   In addition, we cannot assure you that Internet access companies, utility
companies and telecommunications providers will be Year 2000 compliant. The
failure by these companies to be Year 2000 compliant could result in a
systematic failure beyond our control, such as a prolonged Internet,
telecommunications or electrical failure, which could prevent us from
delivering the Audible service to our customers, decrease the use of the
Internet or prevent users from accessing audible.com, would have a material
adverse effect on our business, results of operations and financial condition.

                                    BUSINESS

   We provide premium spoken audio content, such as audio versions of books and
newspapers and radio programs, that is delivered over the Internet and played
back on personal computers and hand-held electronic devices. The Audible
service allows consumers to purchase and download our content from our Web
site, store it in digital files and play it back on personal computers and
electronic devices. More than 15,000 hours of audio content are available on
our Web site, including audio versions of books, periodicals and radio
programs. Several manufacturers have agreed to support and promote the playback
of our content on their hand-held audio-enabled electronic devices.

   The market for the Audible service results from the increasing usage of the
Internet and the recent introduction of hand-held electronic devices that have
audio capabilities. In contrast to traditional radio broadcasts, the Audible
service offers customers access to content of their choice and the ability to
listen to what they want, when and where they want--whether commuting,
exercising, relaxing or sitting at their personal computers. Unlike traditional
and online bookstores which are subject to physical inventory constraints and
shipping delays, we provide a selection that is readily available in digital
format that can be quickly delivered over the Internet directly to our
customers.

   We help publishers, producers, authors, device manufacturers and our Web
site affiliates create incremental sources of revenue. We provide new sources
of revenue for publishers of newspapers, magazines, journals, newsletters,
professional publications and business information and producers of radio
broadcasts. In addition, our service provides companies that distribute or
promote our service and manufacturers of hand-held audio-enabled electronic
devices with a wide selection of content to offer to their customers.

Industry Overview

   Public demand for entertainment, information and educational media continues
to grow as sources for this content proliferate. Veronis, Suhler & Associates
estimates that the communications industry exceeded $300 billion in revenues in
1997, increasing from less than $60 billion in 1977. During 1997, Americans on
average spent more than 3,300 hours reading, watching or listening to media
content from a large number of disparate sources. We believe that many
consumers seek a better way to manage this content.

   Listening is a way for individuals to consume this content at times when
they are unable to read, such as when they are driving. A 1996 market study by
the Yankee Group indicates that 87% of automobile commuters listened to the
radio an average of 50 minutes a day while commuting. According to the
Department of Transportation, in 1990, 84 million people drove to and from work
alone, an increase of 35% from 1980. As individuals look to use their commuting
time more efficiently and manage an increasing amount of available content,
audiobooks have emerged as a personalized "pay-to-listen" alternative to radio,
which does not allow listeners to control when they listen to a particular
program. Americans spent $2.2 billion on spoken word audio tapes in 1998, an
increase from $1.6 billion in 1996. This increasing usage of audiobooks exists
despite limited types of content, high prices and the limitations of cassette
tape players. For instance, the audiobook market does not address timely print
content such as newspapers, newsletters, magazines and journals.

   Recently, the Internet has emerged as a significant global communications
medium enabling millions of people to access and share information. Through the
Internet, users have the ability to quickly receive information in various
forms, from text and multimedia to newer technologies such as streaming audio.
Jupiter Communications estimates that over 33% of all Internet users listen to
Internet-delivered audio on their personal computers. However, the current
audio environment available on the Internet generally restricts consumers to
listening at their personal computers. Consumer electronics and computer
manufacturers are addressing this constraint by developing a new generation of
mobile devices that are capable of playing back downloaded audio content.

                                       29
<PAGE>

   IDC estimates that shipments of hand-held companion devices exceeded 4.5
million units worldwide in 1998 and will increase to over 14 million worldwide
by 2002. We believe seven million of these mobile devices will be audio-enabled
by the year 2002. This estimate does not include the recent appearance of
Internet-connected music players. According to Forrester Research, the
installed base of Internet-connected music players are estimated to reach one
million units in 1999 and 17 million units in 2002.

   The confluence of the Internet as an increasingly accepted media
distribution channel, the widespread adoption of audio-enabled mobile devices
and the continuing growth in consumer demand for content in a variety of
formats, has resulted in new challenges for the media industry. These
challenges include creating a system that takes advantage of revenue
opportunities by making content readily accessible through the Internet while
compensating publishers and other content creators and preventing unauthorized
duplication and distribution. This creates an opportunity for a provider who
can establish a secure system for Internet delivery of premium audio content.

Our Solution

   We have created the Audible service to give consumers the ability to
download spoken audio content of their choice from the Internet and to listen
to this audio when, where and how they want. The Audible service addresses the
market opportunity created by consumer demand for audio content and the
emergence of the Internet and hand-held audio-enabled electronic devices. We
have created the first service for secure delivery of premium digital spoken
audio content over the Internet for playback on personal computers and these
devices. Our service allows customers to program their listening time with
personalized selections from a wide collection of spoken audio content
available on audible.com, our Web site, including entertainment, news,
education and business information. We have assembled the largest and most
diverse collection of premium spoken audio content available for download on
the Internet for playback on personal computers and hand-held electronic
devices in most cases, currently available only through us and, in many cases,
pursuant to exclusive license rights. We have more than 15,000 hours of audio
content available on our Web site, including audio versions of books and
periodicals such as The New York Times, The Wall Street Journal and The
Economist, and radio programs such as Car Talk, Fresh Air, Marketplace and News
From Lake Wobegon. We provide over 3,000 audio versions of books from
publishers, including Bantam Doubleday Dell Audio Publishing and Random House
Audio Publishing, each a division of Random House, Inc., Dove Audio, Harper
Audio, Simon & Schuster Audio and Time Warner AudioBooks, and written by
authors such as Dave Barry, John Grisham, Stephen King, Sidney Sheldon and Amy
Tan. We believe that our extensive audio content collection and our secure
delivery system provide benefits to our customers, content providers,
manufacturers of AudibleReady hand-held electronic devices and other companies
which distribute or promote our service.

 Benefits to Customers:

   Unlike the traditional ways consumers select, organize and consume audio
content, Audible customers can access content of their choice and listen when,
where and how they want--whether commuting, exercising, relaxing or sitting at
their personal computers.

   Selection. At our Web site, audible.com, customers can browse and purchase
from a large and diverse collection of readily available premium spoken audio
content, most of which is currently available only through us in digital format
for Internet distribution either pursuant to exclusive arrangements or because,
to our knowledge, no one else currently has these rights. Our collection
includes over 3,000 digital audiobooks in a wide variety of categories from
more than 1,500 authors. We are the only source of timely digital audio
editions of leading newspapers and selected periodicals. We also offer popular
and special interest radio programming, including interviews, commentaries and
talk radio. Our collection also contains selections that are difficult to find
or may not otherwise be readily or conveniently available to customers, such as
lectures and speeches. We have over 4,400 of these other audio selections in
addition to our audiobooks.

   Convenience. audible.com provides customers with one-stop shopping for their
premium digital spoken audio needs. Our customers can browse and sample spoken
audio selections through our easy to navigate Web site. Our customers can
purchase bundled packages of selected audio content and choose automated
delivery of

                                       30
<PAGE>

timely audio content on a subscription basis. Unlike traditional and online
bookstores, which are subject to physical inventory constraints and shipping
delays, we provide a selection that is readily available in digital format that
can be quickly delivered over the Internet directly to our customers.

   Listening Experience. Unlike radio, which offers limited programming and no
ability for the listener to control broadcast times, our service enables
customers to take greater control of the listening experience. Customers decide
to listen to what they want, when and where they want. Our service allows
customers to skip between selections or individual articles or chapters within
selections. Customers can pause and resume listening where they left off and
can "bookmark" multiple sections of content, rather than be constrained by the
rewind and fast forward functions of cassette tape players.

   Lower Prices. We provide customers with lower priced spoken audio content
because we do not incur the costs of traditional audio content manufacture and
distribution. For example, on June 15, 1999, the unabridged digital audio
version of Stephen King's new novel, The Girl Who Loved Tom Gordon, sold for
$10.95 on audible.com compared to the cassette version price of $23.96 plus
shipping through Amazon.com. By comparison, the manufacturer's suggested retail
price for the same title was $29.95 for cassette tape and $32.00 for compact
disc.

 Benefits to Business Affiliates:

   We help content creators, device manufacturers and other companies which
distribute or promote our service to their customers to create incremental
sources of revenue by aggregating premium audio content and providing a widely-
accepted system for digital spoken audio distribution.

   Content creators. We provide a new source of revenue for publishers of
newspapers, magazines, journals, newsletters, professional publications and
business information and producers of radio broadcasts by creating a new market
for content that is too timely for distribution on cassette tape and too
specialized for widely-broadcast radio programs. Additionally, our electronic
delivery service offers publishers of audiobooks a new distribution channel for
their existing audiobook content. Older publications, including archived or
out-of-print content, when converted to digital audio form, can also provide
additional revenue while incurring relatively low costs for storing and
delivering electronic inventory. Our solution has the benefit of reducing the
risk of audio files being copied without authorization by employing a system
designed to limit playback of audio files to specifically identified personal
computers and hand-held electronic devices.

   Device manufacturers. Major manufacturers of hand-held audio-enabled
devices, such as Casio, Compaq, Everex and Philips, have agreed to support and
promote the playback of our content on their devices. Diamond Multimedia has
agreed to promote our service after we jointly make its next version of its Rio
Internet Music Player compatible with our service. Our service provides these
manufacturers with an attractive application that takes advantage of the audio
capability of their devices, which may, in turn, increase their sales. In most
cases, these manufacturers also receive a percentage of the revenue generated
over a specified period of time by each new Audible customer referred by them
through the purchase of a new device. For example, a purchaser of a Philips
"Nino 510" palm-size device using our software can purchase and download
content from audible.com. Philips will receive a percentage of the revenue
related to content downloaded by this purchaser.

   Companies which distribute or promote our service. We have entered into
marketing agreements with Microsoft, MP3.com, RioPort, RealNetworks, SOFTBANK
Content Services, Broadcast.com, The New York Times and The Wall Street Journal
to promote our content to their customers, either directly or indirectly. In
return, we have access to additional distribution outlets. We have agreed with
some of these companies to share a portion of revenue from sales of our content
to their customers.

Our Strategy

   Our objective is to enhance our position as a leading provider of Internet-
delivered premium spoken audio content. Key elements of our strategy to achieve
this goal include:

   Increase brand awareness. We seek to make "Audible" a recognizable brand. We
intend to use the AudibleReady brand to signify that a device is enabled to
play back Audible content. We plan to enhance brand

                                       31
<PAGE>

awareness of the Audible service and increase visitors to our Web site by
expanding our marketing efforts through online initiatives, such as affiliate
programs, sponsorships, direct e-mail solicitations and banner advertisements.
We will augment this effort with offline initiatives, such as print
advertisements, direct mail, radio advertisements and billboards. Our co-
marketing agreements with AudibleReady device manufacturers, which include
bundling our software and marketing materials with these electronic devices,
are key elements of our plans to make potential customers aware of, and to
encourage them to try, our service. As an incentive for potential customers, we
plan to work with our content providers to offer a selection of free and
discounted content samples. In addition, we seek to enter into agreements with
content providers as well as owners of Internet portals, destinations and
commerce sites to promote co-branded services to Internet users.

   Expand content collection. We plan to acquire more Internet distribution
rights to digital audio versions of books, newspapers, radio broadcasts,
magazines, journals, newsletters, conferences, seminars, performances,
lectures, speeches and television audio tracks. With selected content
providers, we plan to create additional timely digital audio editions of
newspapers, periodicals and other written content not otherwise available to
consumers in audio format. We also intend to differentiate our service by
expanding our collection of original and topic-specific content, building a
collection unconstrained by traditional physical inventory concerns.

   Enable additional electronic devices and systems to be AudibleReady. We
intend to continue to work with the manufacturers of hand-held electronic
devices to support and promote the playback of Audible content on their
devices. In addition to our agreements with Casio, Compaq, Everex and Philips,
we also seek to make AudibleReady future generations of audio players that use
the MP3 audio format, a digital compression format which is currently used
primarily for music playback. For instance, we have an agreement with Diamond
Multimedia to integrate the Audible format and security into future versions of
the Rio, Diamond Multimedia's music player that plays music which can be
downloaded from the Internet. We are a member of the Secure Digital Music
Initiative consortium, or SDMI, and intend to support it in the future. The
stated goal of the SDMI consortium is to bring together the worldwide recording
industry and technology companies to develop an open technology for digital
music security. We are also seeking to expand the AudibleReady program to
include other mobile devices, such as smart phones, other hand-held computing
devices as they become audio-enabled and automobile-based personal computers.

   Continue to improve the customer experience. We intend to make the Audible
service increasingly easy for customers to use and personalize. We intend to
take advantage of the flexibility of our online distribution system to offer a
variety of pricing and subscription models designed to maximize customer
satisfaction and to generate recurring revenue. We intend to enhance
audible.com to make it easier for customers to find specific selections and to
actively suggest selections that might be of interest to them based on their
prior purchasing patterns. We also intend to enhance our AudibleManager
software to make it simpler for customers to manage their personal audio
content selections and automate downloads and transfers of content to mobile
devices. In addition, we plan to improve the Audible system to improve the
clarity and fidelity of the sound and to play music and sound effects.

The Audible Service

   Audible's integrated spoken audio delivery service includes four components:
(1) our Web site, audible.com; (2) our collection of digital audio content; (3)
our software for downloading, managing, scheduling and playing audio
selections; and (4) a variety of AudibleReady devices.

 audible.com

   Our Web site, audible.com, delivers through the Internet a large and diverse
selection of premium digital spoken audio content in a secure format. At
audible.com, visitors can browse, sample, purchase, subscribe, schedule and
download digital audio content. One hour of spoken audio, requiring about two
megabytes of storage, takes approximately 15 minutes to download to a personal
computer using a 28 kbps modem, approximately eight minutes using a 56 kbps
modem or approximately ten seconds using a high speed Internet connection, and
approximately six minutes to transfer the content from the personal computer to
an AudibleReady device.

 Digital audio content

   We currently offer more than 3,000 digital audiobooks and more than 4,400
other audio selections comprising 15,000 hours of digital spoken audio content,
segmented in four categories:

  .  Audiobooks. We offer a wide selection of audiobooks from more than 1,500
     authors. We offer both abridged (usually three to ten hours long) and
     unabridged (usually five to 20 hours long) versions of original works,
     read either by the authors or by professional narrators.

  .  Timely audio editions of print publications. Our service enables the
     timely distribution of audio editions of newspapers and periodicals
     previously available only in print. We offer a 40-minute daily audio
     edition of The New York Times and a twice-daily audio version of The
     Wall Street Journal. We also offer audio editions of The Harvard
     Business Review, The Economist and numerous technology and investment
     newsletters.

  .  Radio broadcasts. We offer popular and special-interest radio programs
     shortly after they are originally broadcast so our customers have the
     flexibility to listen to these programs when and where they want.

  .  Lectures, speeches, performances and other audio. We offer a broad
     selection of lectures, speeches, dramatic and comedic performances,
     educational and self-improvement materials, religious and spiritual
     content, television audio tracks and other forms of spoken audio, many
     of which are difficult to find from any other source. We also offer
     specialty content created exclusively for audible.com. For example, we
     recently entered into an agreement with the comedian and actor Robin
     Williams to create original comedy and other programming for Internet
     distribution exclusively through audible.com on a weekly basis.

   We have licensed Internet distribution rights to audio content from more
than 100 publishers, producers of radio content and other content creators. Our
license agreements are typically for terms of one to three years, and many
provide us with exclusive Internet distribution rights. Under most licensing
arrangements, we pay the content creator a portion of the revenue we receive,
typically a 12% royalty. In some cases, we also pay a guaranteed advance
against the content creator's revenue share.

   In most cases, we license audio recordings from publishers and content
creators. In other cases, such as with The New York Times, the morning read of
The Wall Street Journal, The Economist and The Harvard Business Review, we
create audio versions from the print publication. In all cases, we convert the
audio into our compressed, digital format.

   Some of our content providers include:

     Audio Literature                        CNBC/Dow Jones Business Video
                                           Bantam Doubleday Dell Audio

 Audible software

   Our software consists of AudibleManager and AudiblePlayer for downloading,
managing, scheduling and playing audio selections.

   The second generation of our AudibleManager software was recently made
available on our Web site to be downloaded for use on personal computers.
AudibleManager enables our customers to download and listen to digital spoken
audio content and transfer it to an AudibleReady device for mobile playback.
AudibleManager can also be used to organize individual selections, to specify
listening preferences and to manage delivery options for subscriptions.
Selections that exceed playback time limitations on a customer's hand-held
electronic device can be listened to over successive sessions by reconnecting
the device to the customer's personal computer and initiating a synchronization
command that automatically replaces the sections that have been

                                       35
<PAGE>

played with new content.

  Our AudiblePlayer software enables users of Windows CE-based hand-held
devices to control and customize their listening experience. Unlike cassette
tape or compact disk players, AudibleReady devices allow fast navigation of the
content through section markers and bookmarks that can be set by the user.
Users can skip between selections, individual articles or chapters, effectively
allowing them to control the listening experience.

 AudibleReady devices

   AudibleReady devices are personal computers and other hand-held electronic
devices that have a speaker or an audio output jack and can be enabled to play
back our audio content. The AudibleManager and AudiblePlayer software enable
these devices to receive and play back Audible content and are available for
download from audible.com. Recently, several device manufacturers have bundled
the AudibleManager and AudiblePlayer software in the packaging for their
devices. In addition, some device manufacturers plan to adapt their devices to
support the Audible service. The audio output jack of all of these devices can
work with headphones or a cassette adaptor to enable the content to be played
through a car stereo system.

   We have formed co-marketing relationships with a number of consumer
electronics and computer companies to promote AudibleReady hand-held electronic
devices and our content to consumers. The device manufacturers are generally
required to promote the Audible service through a variety of means, which may
include (1) displaying the AudibleReady logo on their devices, (2) displaying
the AudibleReady logo on the outside of the device package, (3) including our
brochures inside the device package and (4) referring to Audible and
AudibleReady in their brochures and manuals. In most cases, the device
manufacturers receive a percentage of the revenue related to the content
downloaded by the purchasers of their AudibleReady devices. These revenue
sharing arrangements typically last one to two years from the date the device
user becomes an Audible customer.

   We have agreements with Casio, Compaq, Everex and Philips to bundle
AudibleManager and AudiblePlayer with their palm-size, electronic devices
running the Microsoft Windows CE operating system. Devices manufactured by
these companies include:

Both Compaq and Everex have announced that they have experienced delays in the
delivery schedule of their electronic devices due to parts shortages.

   We also have an agreement with Diamond Multimedia, and are in discussions
with Creative Labs, to make future versions of their portable devices
AudibleReady. We seek to enter into agreements with other palm-size device
manufacturers.

                                       36
<PAGE>

   In order to measure consumer behavior, to demonstrate to content providers
the viability of secure digital distribution of audio content and to test the
potential of our business model, we designed, created and sold the first
AudibleReady device, the Audible MobilePlayer. We have sold approximately 2,650
MobilePlayers, which currently list for $149 each and store up to two hours of
spoken audio content, and approximately 480 MobilePlayer PLUS's, which
currently list for $299 each and store up to seven hours of spoken audio
content. We have discontinued designing and manufacturing the MobilePlayer and
MobilePlayer PLUS because we do not believe that there is significant market
potential for a device such as the MobilePlayer that is limited to playing back
only our audio when other multi-functional devices made by well-know
electronics companies are commercially available. Instead, we are focusing on
enabling the Audible service to be played on a variety of devices sold by a
number of manufacturers. We will continue to sell our devices until our
remaining inventory is sold. These devices will continue to work with the
Audible service.

 Other services

   We also provide audio production and hosting services to corporations that
enable them to deliver in digital audio format training, analysis, marketing
and other information to their employees, suppliers and customers.

Technology

   Our solution provides for the distribution of compressed digital spoken
audio files for playback on a personal computer or AudibleReady device. Our
solution is designed to facilitate the secure distribution and playback of
digital audio files to personal computers and hand-held electronic devices in
order to reduce the risk of audio files being copied without authorization.
Audio files are compressed in order to reduce download time and storage space,
are scrambled and targeted to a customer's personal computer or mobile device
where they are decompressed as they are played back.

   Most of the Audible content is encoded using a compression-decompression
technology that we have licensed and to which we have made proprietary
extensions to enable the security features of the system. We intend to support
other compression-decompression technologies in the future, which will offer
customers the flexibility to choose higher fidelity sound in exchange for
increased download time and increased storage requirements. We have designed an
audio production process to record, edit, encode, segment, categorize, secure
and upload content to our Web site. Our Web site, hosted by QWEST, runs on a
Sun server.

   As of June 15, 1999, our research and development team consisted of
approximately ten developers and engineers, as well as several outside
contractors, who develop and upgrade the AudibleManager software, interfaces to
AudibleReady devices, audible.com and the system architecture. Our production
team comprises business developers, professional readers, audio editors, copy
editors, merchandisers and Web authors and editors. As of June 15, 1999, we had
14 employees and several contractors involved in audio production who regularly
produce new audio for the site.

Development and Marketing Relationships

   In addition to our agreements with Casio, Compaq, Everex and Philips to
bundle our software with their hand-held electronic devices and our agreements
with Broadcast.com, The New York Times, The Wall Street Journal, RioPort,
MP3.com and SOFTBANK Content Services to promote our content, we have entered
into development and marketing arrangements with Microsoft, RealNetworks and
Diamond Multimedia for joint software development projects to integrate our
software and content with the products of these vendors.

   Microsoft. Our agreement with Microsoft includes the following development
projects: Windows CE, Microsoft's designation for a special version of its
Windows operating system included in hand-held electronic devices; Digital
Rights Management; Microsoft's electronic books initiative; Microsoft's AutoPC
platform; and Windows Media Player, Microsoft's streaming media playback
software. Microsoft has committed to pay up to $2.0 million in fees over the
next five years for technology development, technology licensing and content
licensing. We have created and licensed a Windows CE software program that
enables Windows CE devices, which have less computing power and memory than a
typical personal computer, to be AudibleReady and play

                                       37
<PAGE>

back Audible content. Under the Digital Rights Management project, we will
incorporate parts of our security software inside a Microsoft platform. We have
also given Microsoft the right to distribute AudibleReady software with
Microsoft's electronic books so that readers of these books can also listen to
them. We are also working with Microsoft to develop its Auto PC platform to be
AudibleReady. We are creating a software program that will allow use of the
Windows Media Player to stream audio through the Internet for listening at a
personal computer with speakers. We have also agreed to share a portion of the
revenue generated over a specified period of time by each new Audible customer
referred by Microsoft through the purchase of a Microsoft device or through the
Microsoft Web site. Microsoft has made a minority investment in our company and
immediately prior to the offering owns approximately 9.4% of our company.

   RealNetworks. Our agreement with RealNetworks has a variety of components.
RealNetworks' personal computer playback software, RealPlayer, enables audio to
stream through the Internet for listening at a personal computer with speakers.
We plan to work with RealNetworks to develop software that will allow users of
RealNetworks' RealPlayer to access, purchase and listen to Audible content. We
also plan to cooperatively distribute portions of Audible content through
RealNetworks' e-commerce initiatives, and we plan to advertise on various
RealNetworks' Web sites.

   Diamond Multimedia. Under the terms of our development and marketing
agreement with Diamond Multimedia, we will collaborate to make the next version
of its Rio Internet Music Player AudibleReady. Our collaboration will
facilitate access to the entire collection of Audible content using our
security, management and playback system. We plan to actively promote the
Audible/Rio service in joint marketing activities, including promotion of
Audible content at RioPort.com, Diamond Multimedia's music Web portal. We and
Diamond Multimedia will share revenue for referring customers to each other. In
addition, we will collaborate to integrate a future release of the
AudibleManager software with a future release of the Rio Manager software.

Sales and Marketing

   Since our inception, we have focused on building our content collection,
developing the Audible service and working with manufacturers to make their
devices AudibleReady. Until recently, we have limited our marketing activities
primarily to public relations and test marketing initiatives. With the
commercial release of Version 2.0 of the AudibleManager software and the
release of new AudibleReady devices, we plan to increase the level and breadth
of our sales and marketing activities. We intend to initially focus our
marketing efforts primarily on commuters and mobile professionals. We intend to
use a combination of online and traditional media methods for sales, marketing
and promotional purposes, including the following:

   Advertising. We plan to use a combination of advertising techniques to
enhance the Audible brand and attract customers to our service. Online
techniques may include free content offers, affiliate programs, sponsorships,
direct e-mail solicitations and banner advertisements. Offline techniques may
include print advertisements, direct mail, radio advertisements, billboards and
retail store promotions.

   Co-marketing. We intend to work with our device manufacturers to promote the
AudibleReady program. We plan to cooperate with content providers to promote
specific Audible content to their customers on a co-branded basis. We plan to
cooperate with RealNetworks to promote Audible content bundles to users of the
RealPlayer and with Microsoft to provide Audible content bundles to users of
Windows Media Player. In addition, we plan to work with portable personal
computer manufacturers to pre-load our AudibleManager software with sample
content and sign-up offers.

   Membership programs. We plan to offer membership programs including volume
discounts at various monthly commitment levels. We may use free and discounted
content offers to encourage our customers to sign up for our new membership
programs. We believe that these new membership programs will improve customer
adoption and retention.

   Personalized marketing. We plan to analyze customers' stated preferences and
observed buying patterns. We will use this information to suggest selections
and to enhance the customers' purchasing and listening experience.

Competition

   The market for the sale and delivery of spoken audio is highly competitive
and rapidly changing. Principal competitive factors in the spoken audio market
include:

  .  selection;

  .  price;

  .  speed of delivery;

  .  protection of intellectual property;

  .  timeliness;

  .  convenience; and

  .  sound quality.

Although we believe that we currently compete favorably with respect to these
factors, we cannot be sure that we can maintain our competitive position
against current or new competitors, especially those with longer operating
histories, greater name recognition and substantially greater financial,
technical, marketing, management, service, support and other resources.

   We compete with (1) traditional and online retail stores, catalogs, clubs
and libraries that sell, rent or loan audiobooks on cassette tape or compact
disc, (2) Web sites that offer streaming access to spoken audio content using
tools such as the RealPlayer or Windows Media Player and (3) other companies
offering services similar to ours.

   Audiobooks on cassette tape or compact disc have been available from a
variety of sources for a number of years. Traditional book stores, such as
Borders and Barnes & Noble, and online book stores, such as barnesandnoble.com
and Amazon.com, offer a variety of audiobooks. The AudioBook Club offers
discounted audiobooks by mail order. Rental services, such as Books on Tape,
offer low pricing for time-limited usage of audiobooks, and libraries loan a
limited selection of audiobooks. One or more of these competitors might develop
a competing electronic service for delivering audio content.

   Competition from Web sites that provide streaming audio content is intense
and is expected to increase significantly in the future. Broadcast.com, which
recently announced plans to be acquired by Yahoo!, and RealNetworks offer a
wide selection of streaming audio content. These companies and other portal
companies including America Online, Excite, Lycos and Infoseek may compete
directly with us by selling premium audio content for download.

   Audiohighway.com also offers downloaded digital audio content for playback
on personal computers. Command Audio has announced plans to deliver audio
content through FM radio frequency for mobile playback.

   Our content providers and other media companies may choose to provide
digital audio content directly to consumers. In addition, a small number of
companies control primary or secondary access to a significant percentage of
Internet users and therefore have a competitive advantage in marketing to those
users. These providers could use or adapt their current technology, or could
purchase technology, to provide a service directly competitive with the Audible
service.

   Many of these companies have significantly greater brand recognition and
financial, technical, marketing and other resources than we do. We also expect
competition to intensify and the number of competitors to increase
significantly in the future as technology advances provide alternative methods
of delivering digital audio content through the Internet, satellite, wireless
data, FM radio frequency or other means.

Intellectual Property and Proprietary Rights

   We regard our patents, copyrights, service marks, trademarks, trade dress,
trade secrets and similar intellectual property as critical to our success. To
protect our proprietary rights, we rely on a combination of patent, trademark
and copyright law, trade secret protection and confidentiality and license
agreements with our

                                       39
<PAGE>

employees, customers, business affiliates and others. Notwithstanding these
precautions, others may be able to use our intellectual property or trade
secrets without our authorization. If we are unable to adequately protect our
intellectual property, it could materially affect our financial performance. In
addition, potential competitors may be able to develop technologies or services
similar to ours without infringing our patents.

   We hold one patent and have filed eight patent applications for some aspects
of the Audible system, two of which have been allowed. We do not know if the
other pending patents will ever be issued and, if issued, if they will survive
legal challenges. Legal challenges to our patents, whether successful or not,
may be very expensive to defend.

   We have applied for registration in the United States of several of our
trademarks and service marks, including "Audible", "audible.com" and
"AudibleReady". "audible.com" has been allowed and "Audible" and "AudibleReady"
have received adverse actions by the Patent and Trademark Office. We do not
know if these marks will be registered or that we will effectively protect the
use of these names. In addition, we have not taken affirmative steps to protect
our trademarks outside of the United States and effective trademark, service
mark, and copyright protection is not necessarily available in every country in
which our services are available online.

   We also license some of our intellectual property to others, including our
AudibleReady technology and various trademarks and copyrighted material. While
we attempt to ensure that the quality of our brand is maintained, others might
take actions that materially harm the value of either these proprietary rights
or our reputation.

   We license technology from others, including our compression-decompression
technology, that we incorporate into the Audible system. If these technologies
become unavailable to us, we would need to license other technology which would
require us to redesign our system and recode our content. Although we are
generally indemnified against claims that technology licensed by us infringes
the intellectual property rights of others, such indemnification is not always
available for all types of intellectual property and proprietary rights and in
some cases the scope of such indemnification is limited. Even if we receive
broad indemnification, third party indemnitors may not have the financial
resources to fully indemnify us in the event of infringement, resulting in
substantial exposure to us. We cannot assure you that infringement or
invalidity claims arising from the incorporation of this technology, resulting
from these claims, will not be asserted or prosecuted against us. These claims,
even if not meritorious, could result in the expenditure of significant
financial and managerial resources in addition to potential redevelopment costs
and delays, all of which could materially adversely effect our business,
operating results and financial condition.

   We attempt to avoid infringing the proprietary rights of others, although we
have not done an exhaustive patent search. Our competitors may claim that we
are infringing their intellectual property and, if they are successful, we may
be unable to obtain a license or similar agreement to use the technology we
need to conduct our business.

Employees

   As of June 15, 1999, Audible had a total of 41 full-time employees -- ten in
research and development, 12 in sales and marketing, 14 in production and five
in general and administrative.

Facilities

   Our headquarters is in Wayne, New Jersey, where we lease approximately
14,000 square feet housing all our full-time employees. We house our server in
a secure facility in Weehawken, New Jersey.

Legal Proceedings

   We are not currently subject to any material legal proceedings. We may from
time to time become a party to various legal proceedings arising in the
ordinary course of its business. Any such proceeding against us, even if not
meritorious, could result in the expenditure of significant financial and
managerial resources.

                  Fiscal 1998 Year-End Restricted Stock Values

   All of our Named Executive Officers own restricted stock. The following
table sets forth, as of December 31, 1998, the total purchases of restricted
stock by each Named Executive Officer and the number and aggregate dollar value
of the vested and unvested shares held by them. There was no public trading
market for our common stock as of December 31, 1998. Accordingly, we have
calculated the aggregate value of the shares based on the difference between an
assumed initial public offering price of $9.00 per share and the purchase price
of each share, multiplied by the number of shares. All these shares were
purchased by the Named Executive Officers at their fair market value, as
determined by our board of directors, and were paid for by promissory note on
the terms described under "Restricted Stock Program."

Restricted Stock Program

   Since our inception, some of our employees have purchased restricted shares
of our common stock at a price per share equal to the fair market value on the
date of purchase as determined by our board of directors. The number of shares
that each employee purchased varied depending on his or her position. In
general, employees paid for these shares by promissory notes, which are due on
the earlier of 50 months from the date of issuance of the shares or the date
the employee leaves Audible.

   In general, we may repurchase a portion of an employee's shares if he or she
ceases to be employed by us. If the employee leaves within six months of
purchasing the restricted stock, we may repurchase all of the employee's
shares. Twelve percent of the employee's shares vest six months after the date
of purchase and thereafter, the remaining shares vest equally over the next 44
months. We may repurchase all unvested shares at the original purchase price.
If we are acquired by another company, 50% of each employee's unvested shares
on that date will automatically become vested.

1999 Stock Incentive Plan

   Our 1999 Stock Incentive Plan authorizes the grant of:

  .  stock options;

  .  stock appreciation rights;

  .  stock awards;

  .  phantom stock; and

  .  performance awards.

   The Compensation Committee administers our Stock Incentive Plan. The
Committee has sole power and authority, consistent with the provisions of our
Stock Incentive Plan, to determine which eligible participants will receive
awards, the form of the awards and the number of shares of our common stock
covered by each award. The Committee may impose terms, limits, restrictions and
conditions upon awards, and may modify, amend, extend or renew awards,
accelerate or change the exercise time of awards or waive any restrictions or
conditions to an award.

   As of June 15, 1999, we have issued options to purchase 903,450 shares of
our common stock out of the 9,000,000 shares available under the Stock
Incentive Plan.

   Stock Options. We can grant options to purchase shares of our common stock
that either are intended to qualify as incentive stock options under the
Internal Revenue Code or that do not qualify as incentive options. The
Committee can determine the option exercise price, the term of each option, the
time when each option may be exercised and, the period of time, if any, after
retirement, death, disability or termination of employment during which options
may be exercised.

   Stock Appreciation Rights. We can grant rights to receive a number of shares
or cash amounts, or a combination of the two that is based on the increase in
the fair market value of the shares underlying the right during a stated period
specified by the Committee.

                                       46
<PAGE>

   Stock Awards. We can award shares of our common stock at no cost or for a
purchase price. These stock awards may be subject to restrictions at the
Committee's discretion.

   Phantom Stock. We can grant stock equivalent rights, or phantom stock, which
entitle the recipient to receive credits which are ultimately payable in the
form of cash, shares of our common stock or a combination of both. Phantom
stock does not entitle the holder to any rights as a stockholder.

   Performance Awards. We can grant performance awards to participants
entitling the participants to receive cash, shares of our common stock, or a
combination of both, upon the achievement of performance goals and other
conditions determined by the committee. The performance goals may be based on
our operating income, or on one or more other business criteria selected by the
Committee.

   Other Stock-Based Awards. We can grant other stock-based awards. These
stock-based awards may be denominated in cash, in common stock, or other
securities, in stock-equivalent units, in stock appreciation units, in
securities or debentures convertible into common stock, or in any combination
of the foregoing and may be paid in common stock or other securities, in cash,
or in a combination of common stock or other securities and cash, all as
determined in the sole discretion of the Committee.

401(k) Plan

   We maintain a 401(k) plan that covers all our employees who satisfy
eligibility requirements relating to minimum age, length of service and hours
worked. We may make an annual contribution for the benefit of eligible
employees in an amount determined by our board of directors. We have not made
any such contribution to date and have no current plans to do so. Eligible
employees may make pretax elective contributions of up to 15% of their
compensation, subject to maximum limits on contributions prescribed by law.

                     RELATED TRANSACTIONS AND RELATIONSHIPS

Organization

   In connection with our formation, we issued 1,500,000 shares of common stock
to our founder, Donald R. Katz, in exchange for a $52,500 promissory note and

and us, based upon Mr. Katz's estimated costs of such patent right, and agreed
to by Mr. Mott, a director, prior to the investment in December 1995 by
Ironwood Capital L.L.C., of which Mr. Mott is a managing member.

   In December 1995, we issued 534,000 shares of Series A preferred stock at a
price of $0.75 per share and 375,000 shares of common stock at a price of
$0.047 per share to Ironwood.

Issuance of Options

shares of common stock at an exercise price of $8.00 per share, subject to

at an exercise price of $4.00 per share to holders of Series C preferred stock,
including Ironwood, the Kleiner Perkins group, the Patricof group, the AT&T

March 31, 2002.

   In April 1999, in connection with an amendment to our license agreement with
Microsoft, which owns over 5% of our capital stock, we issued to Microsoft a
warrant to purchase 100,000 shares of common stock at a price per share equal
to the price to the public of our common stock in this offering, or, if this
offering does not occur within 12 months of the date of issuance, such warrant
is exercisable for 100,000 shares of common stock at $6.00 per share. This
warrant may be exercised until November 18, 2003.

Additional Transactions

   In March 1997, we loaned Mr. Katz, our Chairman of the Board, $100,000 under
the terms of a promissory note and secured by Mr. Katz's pledge of 37,500
shares of common stock. The promissory note bears interest at the rate of 6%
per annum and is due on the earlier of March 28, 2002 or one year following
this offering. On March 31, 1999, the outstanding balance on the loan was
$100,000 plus $12,000 in accrued interest.

   In September 1998, we entered into a software development and licensing
agreement with Compaq Computer Corporation, an affiliate of CPQ Holdings, Inc.,
which owns over 5% of our issued stock.

   In November 1998, we entered into a license agreement with Microsoft. Our
agreement includes the following development projects: Windows CE; Windows
Media Player; Digital Rights Management; Microsoft's electronic books
initiative; and Microsoft's Auto PC platform. Microsoft has committed to pay
certain fees over the next five years for technology development, technology
licensing and content licensing. As part of the agreement, we have created and
licensed a Windows CE software program that enables Windows CE devices to play
back Audible content. We are also working with Microsoft to develop its Auto PC
platform to be Audible Ready. We are creating a software program that will
allow use of the Windows Media Player to access our content. Under the Digital
Rights Management project, we will incorporate our security software inside a
Microsoft platform. We have also given Microsoft the right to distribute our
software with Microsoft's electronic books so that readers can listen to the
books. We have also agreed to share a portion of the revenue generated over a
specific period of time by each new Audible customer referred by Microsoft
through the purchase of a Microsoft device or through the Microsoft Web site.

   The Microsoft agreement also contains a right of first negotiation if we
receive a proposal from another company that could result in our acquisition.
If we receive an unsolicited proposal, or if our board determines to solicit
proposals or otherwise enter into discussions that would result in a sale of a
controlling interest in our company or other merger, asset sale or other
disposition that effectively results in a change of control of the company, we
are required to give written notice to Microsoft. We are under no obligation to
disclose confidential information related to the unsolicited proposal.
Microsoft then has 7 days to provide notice to us that it desires to negotiate
a potential acquisition of Audible by Microsoft. If Microsoft delivers this
notice to us within 7 days, we will negotiate exclusively and in good faith for
21 days from the date of delivery of our initial notice to Microsoft. We are
under no obligation to accept any offer from Microsoft. If we are unable to
negotiate a transaction with Microsoft within the 21-day negotiation period, we
may negotiate with others for a sale of our company. If we do not enter into a
definitive agreement with another party within 6 months from the date we
initially delivered notice to Microsoft, we must restart the notice and
negotiation process. This right terminates no later than November 4, 2003.

   In January 1998, we entered into an agreement with Flextronics International
Ltd. to manufacture the Audible MobilePlayer. The chief executive officer of
Flextronics is a principal of Ironwood, of which Mr. Mott, a director, is also
a principal. As of December 31, 1997, $173,000 was due to Flextronics under the
terms of that agreement, and as of December 31, 1998, $51,000 was due. As part
of our plans to discontinue the design and manufacture of the Audible
MobilePlayer, we plan to terminate this agreement in the second half of 1999.

   We believe that all the transactions described above were made on terms no
less favorable to us than if such transactions were with non-affiliates. We
have adopted a policy whereby all future transactions between us and our
officers, directors and affiliates will be on terms no less favorable than
could be obtained from non-affiliates and will be approved by a majority of our
board.

                             PRINCIPAL STOCKHOLDERS

   The following table sets certain information regarding beneficial ownership
of our common stock as of April 30, 1999, and as adjusted to reflect the sale
of the shares offered hereby, by:

  .  each person who we know beneficially owns more that 5% of our common
     stock;

  .  each member of our board of directors;

  .  each of our Named Executive Officers; and

  .  all directors and executive officers as a group.

   Unless otherwise indicated, the address for each stockholder listed is c/o
Audible, Inc., 65 Willowbrook Boulevard, Wayne, New Jersey 07470. Except as
otherwise indicated, each of the persons named in this table has sole voting
and investment power with respect to all the shares indicated.

   For purposes of calculating the percentage beneficially owned, 21,003,265
shares of common stock are deemed outstanding before the offering, including
7,602,269 shares of common stock outstanding as of April 30, 1999 and
13,400,996 shares of common stock issuable upon conversion of the preferred
stock. For purposes of calculating the percentage beneficially owned, the
number of shares deemed outstanding after the offering includes: (a) all shares
deemed to be outstanding before the offering and (b) 4,000,000 shares being
sold in this offering, assuming no exercise of the underwriters' over-allotment
option.

   In computing the number of shares beneficially owned by a person and the
percentage ownership by that person, shares of common stock which that person
could purchase by exercising outstanding common stock purchase warrants prior
to June 30, 1999, are deemed outstanding. Such shares, however, are not deemed
outstanding for the purpose of computing the percentage ownership of any other
person.

Common Stock

   We are authorized to issue 50,000,000 shares of common stock. Holders of
common stock are entitled to one vote for each share of record on all matters
submitted to a vote of stockholders. The holders of common stock are entitled
to receive ratably such lawful dividends as may be declared by the board of
directors. However, such dividends are subject to preferences that may be
applicable to the holders of any outstanding shares of preferred stock. In the
event of a liquidation, dissolution, or winding up of the affairs of our
company, whether voluntary or involuntary, the holders of common stock will be
entitled to receive pro rata all of our remaining assets available for
distribution to stockholders. Any such pro rata distribution would be subject
to the rights of the holders of any outstanding shares of preferred stock. Our
common stock has no preemptive, redemption, conversion or subscription rights.
Piper & Marbury L.L.P., our counsel, will opine that the shares of common stock
to be issued by us in this offering, when issued and sold in the manner
described in the prospectus and in accordance with the resolutions adopted by
the board of directors, will be fully paid and non-assessable. The rights,
powers, preferences and privileges of holders of our common stock are subject
to, and may be adversely affected by, the rights of the holders of shares of
any series of preferred stock that we may designate and issue in the future.

Preferred Stock

   At the closing of the offering, our outstanding shares of preferred stock
will be automatically converted into common stock. For a description of this
preferred stock, please see note (4) to the notes to financial statements
included elsewhere in this prospectus. Immediately following the offering, our
board will have the authority to designate and issue up to 10,000,000 shares of
preferred stock, in one or more series. Our board can establish the
preferences, rights and privileges of each series, which may be superior to the
rights of the common stock.

   We have no current plans to issue any preferred stock following this
offering. However, if we do so, it could discourage a third party from
attempting to acquire a majority of the our outstanding voting stock.

Warrants

   We have outstanding the following warrants to purchase shares of our common
stock, including warrants previously exercisable to purchase shares of
preferred stock but which, upon completion of this offering, will entitle the
holder to purchase shares of common stock: (1) warrants, to purchase 50,372
shares at an exercise price of $1.79 per share, expiring November 19, 2006, (2)
warrant, to purchase 18,750 shares at an exercise price of $2.67 per share,

offering, these stockholders have the right, after March 31, 2000, upon request

Shares, Series B Registrable Shares, or upon request of the holders of at least

group of Registrable Shares. In addition to these demand registration rights
and, subject to conditions and limitations provided in the agreement, these
stockholders may require us to file an unlimited number of registration
statements on Form S-3 under the Securities Act when such form is available for
our use, generally one year after this offering.

   If we propose to register our securities under the Securities Act after this
offering, these stockholders will be entitled to notice of the registration and
to include their shares in the registration provided that the underwriters of
the proposed offering will have the right to limit the number of shares
included in the registration. One warrantholder also has the right to include
his shares of common stock issued upon exercise of his warrants in the
registration. We must pay for all expenses in connection with these
registrations, other than underwriters' discounts and commissions.

Anti-Takeover Effects of Our Certificate of Incorporation and Bylaws and
Delaware General Corporation Law; Right of First Negotiation

   Our Certificate of Incorporation and Bylaws and Delaware General Corporation
Law. Certain provisions of Delaware law and our certificate of incorporation
and bylaws could make the following more difficult:

  .  the acquisition of us by means of a tender offer;

  .  acquisition of us by means of a proxy contest or otherwise; or

  .  the removal of our incumbent officers and directors.

   These provisions, summarized below, are expected to discourage certain types
of coercive takeover practices and inadequate takeover bids. These provisions
are also designed to encourage persons seeking to acquire control of us to
first negotiate with our board. We believe that the benefits of increased
protection of the potential ability to negotiate with the proponent of an
unfriendly or unsolicited proposal to acquire or restructure us outweigh the
disadvantages of discouraging such proposals because negotiation of such
proposals could result in an improvement of their terms.

                                       55
<PAGE>

 Election and Removal of Directors

   Our board of directors will be divided into three classes. The directors in
each class will serve for a three-year term, one class being elected each year
by our stockholders. This system of electing and removing directors may tend to
discourage a third party from making a tender offer or otherwise attempting to
obtain control of because it generally makes it more difficult for stockholders
to replace a majority of the directors.

   In addition, our by-laws will provide that, except as otherwise provided by
law or our certificate of incorporation, newly created directorships resulting
from an increase in the authorized number of directors or vacancies on the
board may be filled only by

  .  a majority of the directors then in office, though less than a quorum is
     then in office; or

  .  by the sole remaining director.

 Stockholder Meetings

   Under our certificate of incorporation and bylaws, only the board of
directors, the chairman of the board, the president or the holders of at least
a majority of our outstanding stock may call special meetings of stockholders.

 Requirements for Advance Notification of Stockholder Nominations and Proposals

   Our bylaws will establish advance notice procedures with respect to
stockholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of the board of
directors or a committee of the board.

 Delaware Anti-Takeover Law

   We are subject to Section 203 of the Delaware General Corporation Law, an
anti-takover law. In general, Section 203 prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years following the date the person became
an interested stockholder, unless the "business combination" or the transaction
in which the person became an interested stockholder is approved in a
prescribed manner. Generally, a "business combination" includes a merger, asset
or stock sale, or other transaction resulting in a financial benefit to the
interested stockholder. Generally, an "interested stockholder" is a person who,
together with affiliates and associates, owns or within three years prior to
the determination of interested stockholder status, did own, 15% or more of a
corporation's voting stock. The existence of this provision may have an anti-
takeover effect with respect to transactions not approved in advance by the
board of directors, including discouraging attempts that might result in a
premium over the market price for the shares of common stock held by
stockholders.

 Elimination of Stockholder Action By Written Consent

   Our certificate of incorporation will eliminate the right of stockholders to
act by written consent without a meeting, unless the consent is unanimous.

 No Cumulative Voting

   Our certificate of incorporation and bylaws will not provide for cumulative
voting in the election of directors.

 Undesignated Preferred Stock

   The authorization of undesignated preferred stock will make it possible for
our board of directors to issue preferred stock with voting or other rights or
preferences that could impede the success of any attempt to change control of
Audible. These and other provisions may have the effect of deterring hostile
takeovers or delaying changes in control or our company or management.


                                       56

 Limitation Of Liability

   As permitted by the Delaware General Corporation Law, our certificate of
incorporation provides that our directors shall not be personally liable to us
or our stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability:

  .  for any breach of the director's duty of loyalty to us or our
     stockholders;

  .  for acts or omissions not in good faith or that involve intentional
     misconduct or a knowing violation of law;

  .  under Section 174 of the Delaware General Corporation Law, relating to
     unlawful payment of dividends or unlawful stock purchase or redemption
     of stock; or

  .  for any transaction from which the director derives an improper personal
     benefit.

   As a result of this provision, we and our stockholders may be unable to
obtain monetary damages from a director for breach of his or her duty of care.

   Our certificate of incorporation and bylaws will provide for the
indemnification of our directors and officers to the fullest extent authorized
by the Delaware General Corporation Law. The indemnification provided under our
certificate of incorporation and bylaws includes the right to be paid expenses
in advance of any proceeding for which indemnification may be had, provided
that the payment of these expenses incurred by a director or officer in advance
of the final disposition of a proceeding may be made only upon delivery to us
of an undertaking by or on behalf of the director or officer to repay all
amounts so paid in advance if it is ultimately determined that the director or
officer is not entitled to be indemnified. If we do not pay a claim for
indemnification within 60 days after we have received a written claim, the
claimant may at any time thereafter bring an action to recover the unpaid
amount of the claim and, if successful the director or officer will be entitled
to be paid the expense of prosecuting the action to recover these unpaid
amounts.

   Under our bylaws, we will have the power to purchase and maintain insurance
on behalf of any person who is or was one of our directors, officers, employees
or agents, or is or was serving at our request as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against the person or incurred by the
person in any of these capacities, or arising out of the person's fulfilling
one of these capacities, and related expenses, whether or not we would have the
power to indemnify the person against the claim under the provisions of the
Delaware General Corporation Law. We intend to purchase director and officer
liability insurance on behalf of our directors and officers.

  Right of First Negotiation. Pursuant to an agreement with Microsoft,
Microsoft has a right of first negotiation if we receive an unsolicited
proposal, or if our board determines to solicit proposals or otherwise enter
into discussions that would result in a sale of a controlling interest in our
company or other merger, asset sale or other disposition that effectively
results in a change of control of the company. For a description of this
agreement, please see "Related Transactions and Relationships--Additional
Transactions." Microsoft's right of first negotiation could have the effect of
delaying or deterring a change of control.

Stock Transfer Agent

   The transfer agent and registrar for our common stock is American Stock
Transfer and Trust Company.

                        SHARES ELIGIBLE FOR FUTURE SALE

   After this offering, we will have 25,003,265 shares of common stock
outstanding. If the underwriters exercise their over-allotment option in full,
we will have 25,603,265 shares of common stock outstanding. 4,000,000 of the
shares we sell in this offering will be freely tradable without restriction or
further registration under the Securities Act, except that any shares purchased
by our affiliates, as that term is defined in Rule 144, may generally only be
sold in compliance with the limitations of Rule 144, which is summarized below.

   The remaining 84%, or 21,003,265 shares of common stock outstanding after
this offering, will be restricted shares under the terms of the Securities Act,
all of which shares are subject to lock-up agreements as described below.
Restricted shares may be sold in the public market only if registered or if
they qualify for an exemption from registration under Rules 144, 144(k) or 701
promulgated under the Securities Act, and subject to the lock-up requirements
which rules are summarized below. Subject to the lock-up agreements described
below, these restricted shares will be available for resale in the public
market as follows:

<TABLE>

                   prospectus, all of which shares are subject to lock-up agreements
</TABLE>

   Before this offering, there has been no public market for our common stock,
and we cannot predict what effect, if any, that market sales of shares of our
common stock or the availability of shares of our common stock for sale will
have on the market price of our common stock prevailing from time to time.
Sales of substantial amounts of our common stock in the public market could
adversely affect prevailing market prices and could impair our future ability
to raise capital through the sale of our equity securities.

Rule 144

   In general, under Rule 144, beginning 90 days after the effective date of
the offering, a stockholder who owns restricted shares that have been
outstanding for at least one year is entitled to sell, within any three-month
period, a number of these restricted shares that does not exceed the greater
of:

  .  one percent of the then outstanding shares of our common stock, or
     approximately 250,033 shares immediately after this offering; or

  .  the average weekly trading volume in our common stock on the Nasdaq
     National Market during the four calendar weeks preceding the sale.

   In addition, our affiliates must comply with the restrictions and
requirements of Rule 144, other than the one-year holding period requirement,
to sell shares of common stock that are not restricted securities.

   Under Rule 144(k), a stockholder who is not currently, and who has not been
for at least three months before the sale, an affiliate of ours who owns
restricted shares that have been outstanding for at least two years may resell
these restricted shares without compliance with the above requirements. The
one- and two-year holding periods described above do not begin to run until the
full purchase price is paid by the person acquiring the restricted shares from
us or an affiliate of ours.

                                       58
<PAGE>

Rule 701

   Our employees, officers, directors and consultants who purchased our shares
of common stock pursuant to our restricted stock program are entitled to rely
on the resale provisions of Rule 701 under the Securities Act, which permits
affiliates and non-affiliates to sell their Rule 701 shares without having to
comply with Rule 144's holding period restrictions, in each case commencing 90
days after the date of this prospectus. In addition, non-affiliates may sell
Rule 701 shares without complying with the public information, volume and
notice provisions of Rule 144.

Registration Rights

   We have entered into a registration rights agreement with the stockholders
that purchased our preferred stock and warrantholders with which we have
commercial relationships, which holders will own an aggregate of 13,400,996
shares of our common stock, warrants to purchase an aggregate of 1,575,001
shares of our common stock and warrants to purchase 55,261 shares of our
preferred stock, which preferred stock warrants will be exercisable for 82,891
shares of common stock following this offering. These stockholders have
registration rights which, upon exercise, require us to file registration
statements covering the sale of their shares of common stock and to include the
sale of their shares in registration statements covering our sale of shares to
the public. See "Description of our Capital Stock--Registration Rights."

Common Stock and Options Issuable under our Stock Incentive Plan

Act within 180 days after this offering to register up to 9,000,000 shares of
our common stock underlying outstanding stock options or reserved for issuance

statements will be eligible for sale in the public market immediately after the
effective dates of these registration statements, subject to the lock-up
agreements described below.

Lock-up Agreements

   All of our officers and directors and the holders of all of our capital
stock have agreed that they will not, without the prior written consent of
Credit Suisse First Boston Corporation, offer, sell, pledge or otherwise

of our capital stock or publicly announce an intention to effect any of these
transactions, for a period of 180 days from the date of this prospectus.

   Credit Suisse First Boston Corporation currently has no plans to release any
portion of the securities subject to lock-up agreements. When determining
whether or not to release any portion of the securities subject to lock-up
agreements, Credit Suisse First Boston Corporation will consider, among other
factors, the stockholder's reasons for requesting the release, the number of
shares for which the release is being requested and market conditions at the
time.

are subject to certain conditions precedent and that the underwriters will be
obligated to purchase all of the shares of common stock offered in this
offering (other than those shares covered by the over-allotment option
described below) if any are purchased. The underwriting agreement also provides

in our case for grants of employee stock options pursuant to the terms of our
plan in effect on the date hereof, issuances of securities pursuant to the
exercise of employee stock options outstanding on the date hereof or the
exercise of any other stock options outstanding on the date hereof.

   The underwriters have reserved for sale, at the initial offering price, up
to 200,000 shares of common stock for persons associated with Audible who have
expressed an interest in purchasing common stock in this offering including
employees, key people in companies with which we have content, technology or
marketing agreements and other business relationships and friends and family
members of our employees, board members and investors.

   The number of shares of common stock available for sale to the general
public in this offering will be reduced to the extent these persons purchase
the reserved shares. Any reserved shares not so purchased will be offered by
the underwriters to the general public on the same terms as the other shares.

   We have agreed to indemnify the underwriters against liabilities, including
civil liabilities under the Securities Act, or to contribute to payments that
the underwriters may be required to make in respect thereof.

   We have applied to list the shares of common stock on The Nasdaq National
Market under the symbol "ADBL".

   Prior to the offering, there has been no public market for our common stock.
The initial public offering price for the common stock will be determined by
negotiation between us and the representatives.The principal factors to be
considered in determining the initial public offering price include:

  .  the information set forth in this prospectus and otherwise available to
     the representatives;

  .  market conditions for initial public offerings;

  .  the history of and prospects for the industry in which we compete;

  .  our past and present operations;

  .  our past and present earnings;

  .  the ability of our management;

  .  our prospects for future earnings;

  .  the present state of our development and our current financial
     condition;

  .  the recent market prices of, and the demand for, publicly traded common
     stock of companies in businesses similar to ours;

  .  the general condition of the securities markets at the time of this
     offering; and

  .  other relevant factors.

   We can offer no assurances that the initial public offering price will
correspond to the price at which our common stock will trade in the public
market subsequent to the offering or that an active trading market for our
common stock will develop and continue after the offering.

                                       61
<PAGE>


   The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation
M under the Securities Exchange Act of 1934. Over-allotment involves syndicate
sales in excess of the offering size, which creates a syndicate short position.
Stabilizing transactions permit bids to purchase shares of the common stock so
long as the stabilizing bids do not exceed a specified maximum. Syndicate
covering transactions involve purchases of the common stock in the open market
after the distribution has been completed in order to cover syndicate short
positions. Penalty bids permit the representatives to reclaim a selling
concession from a syndicate member when the common stock originally sold by
such syndicate member is purchased in a syndicate covering transaction to cover
syndicate short positions, in stabilization transactions or otherwise. The
representatives track such purchases through the initial public offering
tracking system operated by the Depository Trust Company. The representatives
may, at their discretion, reclaim a selling concession from any syndicate
member whose customer purchased shares in the initial public offering and then
promptly resold all or a portion of such shares to a syndicate member. Such
stabilizing transactions, syndicate covering transactions and penalty bids may
cause the price of the common stock to be higher than it would otherwise be in
the absence of such transactions. These transactions may be effected on The
Nasdaq Stock Market's National Market or otherwise and, if commenced, may be
discontinued at any time.

   Wit Capital, a member of the National Association of Securities Dealers,
Inc., will participate in this offering as one of the representatives of the
underwriters. The National Association of Securities Dealers, Inc. approved the
membership of Wit Capital on September 4, 1997. Since that time, Wit Capital
has acted as an underwriter, e-manager or selected dealer in over 90 public
offerings.

   A prospectus in electronic format is being made available on an Internet Web
site maintained by Wit Capital. In addition, all dealers purchasing shares from

                          NOTICE TO CANADIAN RESIDENTS

Resale Restrictions

   The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that Audible prepare and
file a prospectus with the securities regulatory authorities in each province
where trades of common stock are effected. Accordingly, any resale of the
common stock in Canada must be made in accordance with applicable securities
laws which will vary depending on the relevant jurisdiction, and which may
require resales to be made in accordance with available statutory exemptions or
pursuant to a discretionary exemption granted by applicable Canadian securities
regulatory authority. Purchasers are advised to seek legal advice prior to any
resale of the common stock.

Representations of Purchasers

   Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to Audible and the dealer from whom
such purchase confirmation is received that (i) such purchaser is entitled
under applicable provincial securities laws to purchase such common stock
without the benefit of a prospectus qualified under such securities laws, (ii)
where required by law, such purchaser is purchasing as principal and not as
agent, and (iii) such purchaser has reviewed the text above under "Resale
Restrictions."

Rights of Action (Ontario Purchasers)

   The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
section 32 of the Regulation under the Securities Act (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be readily available,
including common law rights of action for damages or recision or rights of
action under the civil liability provisions of the U.S. federal securities
laws.

Enforcement of Legal Rights

   All of our directors and officers as well as the experts named herein may be
located outside of Canada and, as a result, it may not be possible for Canadian
purchasers to effect service of process within Canada upon the issuer or such
persons. All or a substantial portion of the assets of the issuer and such
persons may be located outside of Canada and, as a result, it may not be
possible to satisfy a judgment against the issuer or such persons in Canada or
to enforce a judgment obtained in Canadian courts against such issuer or
persons outside of Canada.

Notice to British Columbia Residents

   A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by such purchaser pursuant to this offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from Audible. Only one such
report must be filed in respect of common stock acquired on the same date and
under the same prospectus exemption.

Taxation and Eligibility for Investment

   Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and with respect to the eligibility of
the common stock for investment by the purchaser under relevant Canadian
legislation.

                          Independent Auditors' Report

Board of Directors and Stockholders
Audible, Inc.:

   We have audited the accompanying balance sheets of Audible, Inc. (a
development stage company) as of December 31, 1997 and 1998, and the related
statements of operations, stockholders' deficit, and cash flows for each of the
years in the three-year period ended December 31, 1998 and the period November
3, 1995 (date of inception) to December 31, 1998. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Audible, Inc. (a
development stage company) as of December 31, 1997 and 1998, and the results of
its operations and its cash flows for each of the years in the three-year
period ended December 31, 1998 and the period November 3, 1995 (date of
inception) to December 31, 1998 in conformity with generally accepted
accounting principles.

                         Notes to Financial Statements

December 31, 1996, 1997 and 1998 and the period November 3, 1995 (Date of
Inception) to December 31, 1998 three months ended March 31, 1998 and 1999 and
the period November 3, 1995 (Date of Inception) to March 31, 1999
 (All information for the three months ended March 31, 1998 and subsequent to
                        December 31, 1998 is unaudited)

(1) Description of Business

     Audible, Inc. (Audible or the Company) was incorporated on November 3,
  1995 and is currently in the development stage. The Company was formed to
  create the Audible service, a solution delivering premium digital spoken
  audio content over the Internet for playback on personal computers and
  mobile devices. The Company commenced commercial operations in October
  1997. Currently, Audible has spoken audio programming available for
  download from its Web site, audible.com. Customers can purchase programs
  and listen from their personal computers or on the Audible MobilePlayer,
  the Company's proprietary playback device.

(2) Summary of Significant Accounting Policies

  Basis of Presentation

     The Company is currently in the development stage, as revenue generated
  from the Company's principal operations is not yet significant.

     The accompanying financial statements retroactively reflect the effect
  of a 3 for 2 stock split in the form of a stock dividend declared and
  payable by the Company effective May 26, 1999 to stockholders of record at
  the close of business on May 26, 1999. Accordingly, all share and per share
  data has been adjusted to reflect such split (see note 15).

  Interim Financial Information

     The financial statements as of March 31, 1999 and for the three months
  ended March 31, 1999 and 1998 and the period November 3, 1995 (date of
  inception) to March 31, 1999 are unaudited but, in the opinion of
  management, reflect all adjustments which are of a normal, recurring
  nature, necessary for the fair presentation of financial position and
  results of operations. Operating results for the three months ended March
  31, 1999 are not necessarily indicative of the results that may be expected
  for a full year.

  Cash Equivalents

     The Company considers short-term, highly liquid investments with an
  original maturity of three months or less to be cash equivalents. Cash
  equivalents at December 31, 1997 and 1998 were $546,577 and $10,294,043,
  respectively.

  Royalties

     Advance royalty payments in the accompanying balance sheets represent
  payments made to various content providers pursuant to minimum guarantees
  under their royalty agreements. These agreements give the Company the right
  to sell digital audio content over the Internet. These payments are being
  amortized on a straight-line basis over the term of the royalty agreements
  or are expensed as royalties are earned by the content providers under the
  agreements, whichever is sooner. Royalty expense is included in cost of
  content and services revenue in the accompanying statements of operations
  and includes the following
  components:

  Inventory

     Inventory is stated at the lower of cost, principally using the first-
  in, first-out method, or market (net realizable value). Inventory consists
  of Audible MobilePlayers and accessories to the Audible MobilePlayers. The
  Company recorded a charge of $195,317 and $286,603 in 1997 and 1998,
  respectively, to write down inventory to market value. These charges are
  included in cost of hardware revenue in the accompanying statements of
  operations. The 1998 write-down is in addition to the write-down discussed
  in note 5.

  Stock-Based Compensation

     The Company applies Accounting Principles Board Opinion No. 25,
  "Accounting for Stock Issued to Employees," in accounting for its stock-
  based compensation, as permitted by Statement of Financial Accounting
  Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation." SFAS
  No. 123 establishes a fair value-based method of accounting for stock-based
  compensation and requires pro-forma disclosure of net loss and net loss per
  common share as if the fair value-based method of accounting for stock-
  based compensation, as defined in SFAS No. 123, had been applied. No awards
  have been granted under the Company's Stock Incentive Plan to date.

                         (A Development Stage Company)

                         Notes to Financial Statements

December 31, 1996, 1997 and 1998 and the period November 3, 1995 (Date of
Inception) to December 31, 1998 three months ended March 31, 1998 and 1999 and
the period November 3, 1995 (Date of Inception) to March 31, 1999
 (All information for the three months ended March 31, 1998 and subsequent to
                        December 31, 1998 is unaudited)


  Property and Equipment

     Property and equipment is stated at cost. Depreciation is calculated
  using the straight-line method over the estimated useful lives, which are
  three years for computer server and Web site equipment and two years for
  office furniture and equipment, studio equipment, and molds and
  manufacturing equipment.

     Leasehold improvements are amortized on a straight-line basis over the
  lease term or the estimated useful life of the improvement, whichever is
  shorter.

     Maintenance and repairs are expensed as incurred.

  Stock Issued for Goods and Services

     The Company accounts for stock issued to nonemployees in which goods or
  services are the consideration received for the stock issued based on the
  fair value of the goods or services received or the fair value of the stock
  issued, whichever is more reliably measurable.

  Intangible Assets

     Intangible assets consist of a patent which is carried at cost and
  amortized on a straight-line basis over the estimated useful life of three
  years.

  Risks and Uncertainties

     Inherent in the Company's business are various risks and uncertainties,
  including its limited operating history, unproven business model and the
  limited history of electronic commerce on the Internet. The Company's
  success will depend in part upon the emergence of the Internet as a
  communications medium, the availability of spoken audio content, sales of
  third party mobile devices and market acceptance of the Audible service.

  Use of Estimates

     The preparation of financial statements in conformity with generally
  accepted accounting principles requires management to make estimates and
  assumptions that affect the reported amounts of assets and liabilities,
  disclosure of contingent assets and liabilities at the date of the
  financial statements, and reported amounts of revenues and expenses during
  the period. Actual results could differ from those estimates.

  Revenue Recognition

     Hardware revenue is recognized upon shipment. Content revenue is
  recognized in the period when the content is downloaded and the customer's
  credit card is processed. Service revenue is recognized as services are
  performed and consists of audio production and hosting services.

     Other revenue for the three months ended March 31, 1999 and the period
  November 3, 1995 (date of inception) to March 31, 1999 relates to fees
  billed for services under the agreement with Microsoft Corporation
  (Microsoft).

                         Notes to Financial Statements

December 31, 1996, 1997 and 1998 and the period November 3, 1995 (Date of

                        December 31, 1998 is unaudited)


  Research and Development

     Research and development expenses are expensed as incurred. Included in
  research and development are costs incurred under an agreement with IDEO
  Development Corporation (IDEO), under which IDEO developed the Audible
  MobilePlayer, as well as costs incurred in developing the Company's Web
  site and the software that enables customers to download content from the
  Company's Web site. The Company paid IDEO related costs of $913,244,
  $1,044,420, $70,937 and $2,028,601 in 1996, 1997, 1998 and the period
  November 3, 1995 (date of inception) to December 31, 1998, respectively.

  Production Expenses

     Production expenses are expensed as incurred and consist primarily of
  personnel and outsourced costs to support the Company's infrastructure and
  systems including its Web site, internal data communications, audio
  production activities and acquisition of content.

  Advertising Expenses

     The Company expenses the costs of advertising and promoting its products
  and services as incurred. These costs are included in sales and marketing
  in the accompanying statements of operations and totaled $0, $91,295,
  $310,033 and $401,328 for the years ended December 31, 1996, 1997 and 1998
  and for the period November 3, 1995 (date of inception) to December 31,
  1998, respectively.

  Income Taxes

     The Company accounts for income taxes using the asset and liability
  method of SFAS No. 109, "Accounting for Income Taxes." Under the asset and
  liability method, deferred tax assets and deferred tax liabilities are
  recognized for the future tax consequences attributable to differences
  between the financial statement carrying amounts of existing assets and
  liabilities and their respective tax bases and operating loss and tax
  credit carryforwards. Deferred tax assets and liabilities are measured
  using enacted tax rates expected to apply to taxable income in the years in
  which those temporary differences are expected to be recovered or settled.
  The effect on deferred tax assets and liabilities of a change in tax rates
  is recognized in results of operations in the period in which the tax
  change occurs.

  Impairment of Long-Lived Assets

     The Company accounts for long-lived assets in accordance with the
  provisions of SFAS No. 121, "Accounting for the Impairment of Long-Lived
  Assets and for Long-Lived Assets to be Disposed Of." SFAS No. 121 requires
  that long-lived assets and certain identifiable intangibles be reviewed for
  impairment whenever events or changes in circumstances indicate that the
  carrying amount of an asset may not be recoverable. Recoverability of
  assets to be held and used is measured by a comparison of the carrying
  amount of an asset to future net cash flows expected to be generated by the
  asset. If such assets are considered to be impaired, the impairment to be
  recognized is measured as the amount by which the carrying amount of the
  assets exceeds the fair value of the assets. Assets to be disposed of are
  reported at the lower of the carrying amount or fair value less costs to
  sell.

                         (A Development Stage Company)

                         Notes to Financial Statements

December 31, 1996, 1997 and 1998 and the period November 3, 1995 (Date of
Inception) to December 31, 1998 three months ended March 31, 1998 and 1999 and
the period November 3, 1995 (Date of Inception) to March 31, 1999
 (All information for the three months ended March 31, 1998 and subsequent to
                        December 31, 1998 is unaudited)

  Basic and Diluted Net Loss Per Common Share

     Basic and diluted net loss per common share is presented in accordance
  with the provisions of SFAS No. 128, "Earnings Per Share." Basic net loss
  per common share excludes dilution for common stock equivalents and is
  computed by dividing net loss available to common stockholders by the
  weighted average number of common shares outstanding for the period.
  Diluted net loss per common share reflects the potential dilution that
  could occur if securities or other contracts to issue common stock were
  exercised or converted into common stock and resulted in the issuance of
  common stock. Diluted net loss per common share is equal to basic net loss
  per common share, since all common stock equivalents are antidilutive for
  each of the periods presented.

     Diluted net loss per common share for the years ended December 31, 1996,
  1997, 1998 and the period November 3, 1995 (date of inception) to December
  31, 1998 does not include the effects of warrants to purchase 0, 674,999,
  674,999 and 674,999 shares of common stock, respectively; warrants to
  purchase 46,082, 58,270, 63,270 and 63,270 shares of preferred stock
  warrants, respectively; 2,584,000, 4,834,000, 8,684,000 and 8,684,000
  shares of convertible preferred stock on an "as-if" converted basis,
  respectively; as the effect of their inclusion is antidilutive during each
  period.

  Pro Forma Information

     Pro forma basic and diluted net loss per common share has been presented
  as if the convertible preferred stock were converted into common stock for
  all periods presented due to the automatic conversion upon the closing of
  the Company's initial public offering.

     The March 31, 1999 pro forma unaudited balance sheet has been presented
  as if the convertible preferred stock were converted into common stock due
  to the automatic conversion upon the closing of the Company's initial
  public offering. Since no dividends will be paid on the preferred stock,
  there is no pro forma liability reflected for the payment of dividends.

  Financial Instruments and Concentration of Risk

     Financial instruments that potentially subject the Company to
  significant concentrations of credit risk consist of cash and cash
  equivalents, accounts receivable, accounts payable and accrued expenses. At
  December 31, 1997 and 1998, the fair values of these financial instruments
  approximated their carrying value due to the short-term nature of these
  instruments.

  Recent Accounting Pronouncements

     As of January 1, 1998, the Company adopted the provisions of SFAS No.
  130, "Reporting Comprehensive Income," which establishes standards for
  reporting and displaying comprehensive income and its components in a full

Inception) to December 31, 1998 three months ended March 31, 1998 and 1999 and

  public enterprise reports information about operating segments in annual
  financial statements, and requires that those enterprises report selected
  information about operating segments in interim financial reports issued to
  shareholders. It also establishes standards for related disclosures about
  products and services, geographic areas and major customers. SFAS No. 131
  is effective for fiscal years beginning after December 1, 1997. In the
  initial year of application, comparative information for earlier years must
  be restated. The Company has determined that it does not have any
  separately reportable business segments.

     In April 1998, the American Institute of Certified Public Accountants
  (AICPA) issued Statement of Position 98-1, "Accounting for the Cost of
  Computer Software Developed or Obtained for Internal Use" (SOP 98-1), which
  provides guidance (i) for determining whether computer software is
  internal-use software and (ii) on accounting for the proceeds of computer
  software originally developed or obtained for internal use and then
  subsequently sold to the public. It also provides guidance on
  capitalization of the costs incurred for computer software developed or
  obtained for internal use. SOP 98-1 is effective for fiscal years beginning
  after December 31, 1998. The Company does not expect the adoption of SOP
  98-1 in 1999 to have a material effect on its financial statements.

     In April 1998, the AICPA issued Statement of Position 98-5, "Reporting
  on the Costs of Start-up Activities" (SOP 98-5). SOP 98-5, which is
  effective for fiscal years beginning after December 15, 1998, provides
  guidance on the financial reporting of start-up costs and organization
  costs. It requires costs of start-up activities and organization costs to
  be expensed as incurred. The Company does not expect the adoption of SOP
  98-5 in 1999 to have a material effect on its financial statements.

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
  Instruments and Hedging Activities," which establishes accounting and
  reporting standards for derivative instruments, including derivative
  instruments embedded in other contracts, and for hedging activities. SFAS
  No. 133 is effective for all fiscal quarters of fiscal years beginning
  after June 15, 1999. This statement is not expected to affect the Company,
  as it currently does not engage or plan to engage in derivative instruments
  or hedging activities.

  preferred stock shares outstanding as of December 31, 1998.

  Automatic Conversion

     Upon the closing of a Qualified Offering (as defined below), all of the
  then outstanding shares of preferred stock are automatically converted into
  shares of common stock at the conversion price at the time in effect for
  such preferred stock, and any dividends declared but unpaid are immediately
  payable in cash. A "Qualified Offering" is defined as an underwritten
  offering by the Company of authorized but unissued shares of common stock
  at a price per share which (after deducting underwriting commissions and
  offering expenses) is not less than $4.00 per share (adjusted for the 3 for
  2 split), subject to adjustment, and resulting in net proceeds to the
  Company (after deducting underwriting commissions and offering expenses) of
  not less than $15,000,000. An "Underwritten Offering" is defined as a
  distribution of common stock in a firm commitment underwritten public
  offering to the general public pursuant to a registration statement filed

     Upon liquidation, holders of Series A convertible preferred stock are
  entitled to $.75 per share of Series A convertible preferred stock
  outstanding, plus 8% of the original purchase price of Series A convertible

  any declared but unpaid dividends.

     Holders of Series B convertible preferred stock are entitled to the
  greater of (a) the sum of $1.50 per share of Series B convertible preferred
  stock outstanding (subject to adjustment, as defined in the Company's
  Certificate of Incorporation, as amended) plus all declared but unpaid

(5) Write-down Related to Hardware Business

     In 1998, the Company decided to discontinue manufacturing the Audible
  MobilePlayer and instead to focus its efforts on developing the technology
  to enable third-party hand-held devices to download Audible's content. As a
  result, the Company recorded a charge of approximately $370,000 to reduce
  the remaining inventory to its net realizable value. The Company also
  recorded an impairment loss of approximately $181,000 on certain molds and
  manufacturing equipment that were used by Flextronics, Inc. (Flextronics)
  in manufacturing the Audible MobilePlayer. The impairment loss was measured
  as the difference between the fair value, determined to be zero, and the
  carrying value of the molds and manufacturing equipment. In addition, the
  Company recorded a charge of $51,000 and agreed to use its $350,000 deposit
  with Flextronics to satisfy $401,000 in remaining purchase commitments.
  These charges comprise the write-down of approximately $952,000 recorded in
  the accompanying 1998 statement of operations.

                         Notes to Financial Statements

December 31, 1996, 1997 and 1998 and the period November 3, 1995 (Date of
Inception) to December 31, 1998 three months ended March 31, 1998 and 1999 and
the period November 3, 1995 (Date of Inception) to March 31, 1999
 (All information for the three months ended March 31, 1998 and subsequent to
                        December 31, 1998 is unaudited)

     Property and equipment includes equipment under capital leases.
  Depreciation and amortization expense on property and equipment, including
  equipment under capital leases, totaled $28,683, $379,323, $665,711 and
  $1,073,717 in 1996, 1997, 1998 and the period November 3, 1995 (date of
  inception) to December 31, 1998, respectively.

     An impairment loss of approximately $181,000 was recorded on molds and
  manufacturing equipment in 1998 to reduce the net book value to zero since
  the Company determined that the carrying amount of the molds and
  manufacturing equipment was not recoverable.

(7) Microsoft Agreement

     In November 1998, the Company entered into a five-year agreement with
  Microsoft to develop certain integration of products, grant various rights
  and licenses, and provide for Microsoft to be paid future royalties for
  content distributed as a result of the software developed in the agreement.
  Under the terms of the agreement, Microsoft committed a minimum of $2.0
  million in payments to the Company to integrate certain products and
  acquire various rights and licenses.

     Microsoft advanced Audible $1,500,000 in November 1998 in consideration
  of Audible granting Microsoft the right to distribute software enabling
  users of Microsoft platforms to access and use Audible content. This
  advance will be recognized as revenue on a straight line basis over the
  initial term of the agreement which runs through the second quarter of
  2001, beginning in the quarter ended June 30, 1999.

     Audible will pay Microsoft a royalty on content licensed and distributed
  by Audible to each end user that accesses its content using the developed
  software. Royalties will be recognized during the period that the related
  content revenue is earned. During 1998, Audible had not made any royalty
  payments to Microsoft.

     Also under the agreement, Audible (i) has performed technology
  integration services for which the Company has recognized revenue of
  $200,000, (ii) will deliver a license for certain technology rights in
  exchange for $250,000 and (iii) will deliver 300 Audible MobilePlayers in
  exchange for $50,000. The technology integration services have been
  performed and therefore the related revenue has been recognized during the
  three months ended March 31, 1999. Revenue for the technology rights will
  be recognized when delivered and acceptance has occurred. Revenue from the
  sale of Audible MobilePlayers will be recognized when shipped. Microsoft
  has options under the agreement to acquire additional rights and licenses
  and extend the term of the agreement for additional financial
  consideration.

(8) Income Taxes

     There is no provision for income tax expense in 1996, 1997 or 1998 or in
  the period November 3, 1995 (date of inception) to December 31, 1998 due to
  the Company's net losses in each of the years and the cumulative period
  since inception. No income tax payments have been made in 1996, 1997, 1998
  or the period November 3, 1995 (date of inception) to December 31, 1998.

</TABLE>

     In assessing the realizability of deferred tax assets, the Company
  considers whether it is more likely than not that some portion or all of
  the deferred tax assets will not be realized. The ultimate realization of
  deferred tax assets is dependent upon the generation of future taxable
  income. Based on the Company's historical net losses, management believes
  it is more likely than not that the Company will not realize the benefits
  of these deferred tax assets, and accordingly, a full valuation allowance
  has been recorded on the deferred tax assets as of December 31, 1997 and
  1998.

     As of December 31, 1998, the Company has net operating loss
  carryforwards for federal income tax purposes of approximately $10.7
  million which expire between 2010 and 2013 if not used to offset future
  taxable income. The Company has experienced certain ownership changes
  which, under the provisions of Section 382 of the Internal Revenue Code of
  1986, as amended, may result in an annual limitation on the Company's
  ability to utilize its net operating losses in the future.

(9)  Related-party Transactions

     The Company has an agreement with Flextronics to manufacture the Audible
  MobilePlayer. The chief executive officer of Flextronics is also a
  principal of one of the Company's stockholders. Included in accounts
  payable is approximately $173,000 and $51,000 which is due to Flextronics
  at December 31, 1997 and 1998, respectively. The Company intends to
  terminate this agreement in 1999 in connection with the decision to
  discontinue manufacturing the Audible MobilePlayer (see note 5).

     The note receivable due from stockholder of $100,000 at December 31,
  1997 and 1998 bears interest at 6% annually. The principal amount plus
  accrued interest is due the earlier of March 28, 2002 or the effective date
  of an initial public offering by the Company. The stockholder has pledged
  37,500 shares of common stock as security under the promissory note.

     In April 1999, the note was amended to extend its maturity date to one
  year following the closing of an initial public offering of the Company's
  common stock.

(10)  Commitments

  Lease Obligations

     The Company entered into a capital lease line of credit with Comdisco,
  Inc. whereby the Company may lease up to $1,750,000 of equipment. The
  Company has leased $1,240,585 of equipment under this capital lease line as
  of December 31, 1998. The Company has operating leases on its office space
  and certain equipment. Future minimum lease obligations under these lease

  Content Royalty Agreements

     The Company enters into content royalty agreements with various content
  providers. Royalties for licensed content are based on a percentage of
  content revenue. Minimum royalties of approximately $702,000 are required
  to be paid over the next two to three years. Payment dates are based upon
  specific terms within each agreement.

  Purchase Commitment

     Under the Company's manufacturing agreement with Flextronics, the
  Company is required to reimburse Flextronics for all purchases of
  components in connection with its decision to discontinue manufacturing
  Audible MobilePlayers, which amount is approximately $401,000 as of
  December 31, 1998. As of December 31, 1998, the parties agreed to use the
  Company's $350,000 deposit to satisfy a portion of this commitment and the
  Company recorded a charge of $51,000 for the remaining amount (see note 5).
  The Company has committed to purchase a limited quantity of enhanced
  Audible MobilePlayers for approximately $141,000 in early 1999 which are
  expected to be sold at or above cost.

  License Agreements

     In November 1998, the Company entered into a two-year agreement for
  certain joint software development, licensing and marketing. Audible is
  required to pay $250,000 in the aggregate at various dates during 1999
  under the terms of this agreement, for both royalties, based on future
  sales, and advertising costs.

     The Company has entered into several other agreements whereby certain
  device manufacturers will license software from Audible. Under the terms of
  these agreements, the Company would be required to pay the device

                         (A Development Stage Company)

                         Notes to Financial Statements

December 31, 1996, 1997 and 1998 and the period November 3, 1995 (Date of
Inception) to December 31, 1998 three months ended March 31, 1998 and 1999 and
the period November 3, 1995 (Date of Inception) to March 31, 1999
 (All information for the three months ended March 31, 1998 and subsequent to
                        December 31, 1998 is unaudited)


  Web Hosting Agreement

     During 1998, the Company entered into an agreement for Web hosting and
  Internet access services effective until May 1999. Future payments by the
  Company under this agreement total approximately $33,800, to be paid
  monthly.

(11) Notes Due from Stockholders for Common Stock

     Notes due from stockholders of $596,375 and $1,040,158 at December 31,
  1997 and 1998, respectively, were received by the Company for payment for
  shares of common stock purchased by employees and consultants under the
  Company's Stock Restriction Agreements (see note 3). These notes have been
  reflected as a reduction to stockholders' deficit. The notes are full
  recourse promissory notes bearing interest at fixed rates ranging from 7.0%
  to 8.5%. The notes mature beginning in the year 2000.

     The Company has exercised its right to purchase shares of unvested stock
  from employees who were terminated (under the terms of the Company's Stock
  Restriction Agreement). During 1996, 1997, 1998 and the period November 3,
  1995 (date of inception) to December 31, 1998, the Company repurchased
  215,100, 233,055, 1,172,724 and 1,620,879 shares, respectively. The Company
  paid for these shares by reducing the indebtedness under the promissory
  notes issued to the Company.

     Certain Stock Restriction Agreements with employees contain a provision
  whereby the employee is awarded a one-time bonus if still employed by the
  Company on the due date of the promissory note equal to the amount of the
  promissory note. Compensation expense is recognized on a straight-line
  basis over the term of the promissory note. Deferred compensation in the
  accompanying balance sheets represents the earned, unpaid portion of such
  bonuses.

(12) Credit Facilities

     The Company had a bank line of credit which provided for borrowings of
  up to $500,000. No amounts were outstanding under this line of credit as of
  December 31, 1997. This credit facility was secured by interests in various
  Company assets. The credit facility expired on December 31, 1997.

     In April 1998, the Company entered into a $1,000,000 bank line of credit
  agreement. The agreement matures on April 5, 1999 and contains a minimum
  tangible net worth covenant, as defined in the agreement, of $1,500,000.
  Any loan amount bears interest at a per annum rate equal to one percentage
  point above the prime rate (8.75% as of December 31, 1998) and is limited
  to a borrowing base formula based on eligible accounts. As of December 31,
  1998, the amount available for borrowing under the line of credit was
  nominal. The Company did not draw on this line of credit and was in
  compliance with the covenant as of December 31, 1998.

     In connection with securing the $1,000,000 line of credit, the Company
  issued warrants to the bank to purchase 5,000 shares of Series D
  convertible preferred stock. These warrants have an exercise price of $4.00
  per share and expire on April 5, 2003.

     The Company pledged all goods and equipment, including inventory,
  accounts receivable, contract rights and intangibles currently owned or
  hereafter acquired, as collateral under this loan agreement.

                         Notes to Financial Statements

December 31, 1996, 1997 and 1998 and the period November 3, 1995 (Date of
Inception) to December 31, 1998 three months ended March 31, 1998 and 1999 and
the period November 3, 1995 (Date of Inception) to March 31, 1999
 (All information for the three months ended March 31, 1998 and subsequent to
                        December 31, 1998 is unaudited)


     The bank line of credit expired as of April 5, 1999 and was not renewed.

(13) Corporate Restructuring

     On February 2, 1998, the Company reduced its workforce by 32%,
  eliminating 15 full-time positions in a variety of functions. The Company
  offered a severance package to all the terminated employees. The total
  charge resulting from severance of $44,462 was paid in 1998.

(14) Employee Benefit Plan

     On July 1, 1998, the Company adopted and made available to all of its
  employees a 401(k) savings plan (the Plan). The Plan is based on
  contributions from employees and discretionary Company contributions. The
  Company has not contributed to the Plan to date.

(15) Subsequent Events

     In April 1999, the Company established the 1999 Stock Incentive Plan
  (the "Stock Incentive Plan") and has reserved 9,000,000 shares to be issued
  under the Stock Incentive Plan. The Stock Incentive Plan permits the
  granting of stock options, stock appreciation rights, restricted or
  unrestricted stock awards, phantom stock, performance awards and other
  stock-based awards. No awards have been granted under the Stock Incentive
  Plan.

     In April 1999, the Company increased the number of shares of common
  stock authorized from 16,000,000 to 50,000,000 and the number of shares of
  preferred stock authorized from 9,843,000 to 19,843,000.

     In April 1999, in connection with an amendment to the agreements with
  Microsoft, the Company issued to Microsoft a warrant to purchase 100,000
  shares of common stock at the initial public offering price, or, if the
  initial public offering does not occur within 12 months of the date of
  issuance, such warrant is exercisable for 100,000 shares of common stock at
  $6.00 per share. Microsoft has a right of first negotiation in the event of
  a potential sale of the Company. The fair value of this warrant will be
  recognized as an expense on a straight line basis over the same period as
  the advance for the distribution right discussed in note 7.

     Effective May 26, 1999, the Company declared a 3 for 2 stock split in
  the form of a stock dividend payable on May 26, 1999 for stockholders of
  record at the close of business on May 26, 1999.

     In June 1999, in connection with a services agreement, the Company
  issued a warrant to purchase 150,000 shares of common stock at $0.01 per
  share, which is fully vested, and a warrant to purchase 750,000 shares of
  common stock at $8.00 per share, which is subject to vesting over a five
  year period. The fair value of these warrants will be recorded as an
  expense over the initial term of the service agreement, which is three
  years.

     Subsequent to March 31, 1999, the Company has substantially completed
  its development efforts in establishing its business and, accordingly, no
  longer considers itself to be a development stage company.

14. Indemnification of Officers and Directors

   Section 145 of the Delaware General Corporation Law ("Section 145") permits
indemnification of directors, officers, agents and controlling persons of a
corporation under certain conditions and subject to certain limitations. Our
bylaws include provisions to require us to indemnify our directors and officers
to the fullest extent permitted by Section 145, including circumstances in
which indemnification is otherwise discretionary. Section 145 also empowers us
to purchase and maintain insurance that protects our officers, directors,
employees and agents against any liabilities incurred in connection with their
service in such positions.

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

   The form of Underwriting Agreement filed as Exhibit 1.1 to this Registration
Statement provides for indemnification of our directors and officers by the
Underwriters, for certain liabilities arising under the Securities Act.

15. Recent Sales of Unregistered Securities

Act, relating to sales not involving any public offering, Rule 506 of the
Securities Act relating to sales to accredited investors and Rule 701 of the
Securities Act relating to a compensatory benefit plan. The sales were made
without the use of an underwriter and the certificates representing the
securities sold contain a restrictive legend that prohibits transfer without
registration or an applicable exemption.

   (b) Financial Statement Schedules:

   Schedules have been omitted because the information required to be shown in

17. Undertakings

   The undersigned Registrant hereby undertakes to provide to the underwriter
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

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

   The undersigned Registrant hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act,
the information omitted form the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.

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

           b.  create an HTML-based web page that will, when accessed by a user
     of Windows Media Player dynamically assemble an application from Microsoft-
     provided components and other software components, which application, when
     combined with the Audible Media Player Filter and other required user
     interface elements, facilitates Windows Media Player-based playback of
     Content.  Audible shall use and make secure one or more Microsoft-provided
     CODECs, as necessary to decode the Audible Content using the Windows Media
     Player through the Web page described in the preceding sentence.

     1.2.  The Windows CE Platform.  Audible, with the assistance and
           -----------------------
development tools from Microsoft described in Article 2 below, shall develop the
Audible Software for Windows CE in accordance with written specifications
mutually agreed to by both parties.  The Audible Software for Windows CE shall
initially be designed for Windows CE for the Palm-size PC and Windows CE for the
AutoPC.  Other versions of Windows CE may be added to this Development Work as
determined by mutual written agreement of Microsoft and Audible, including
agreement regarding any compensation to be paid to Audible for its additional
development effort.

     1.3.  Synchronize Sound With Text.  Audible shall exercise reasonable
           ---------------------------
efforts, jointly with Microsoft, to evaluate and implement the use of the ASF
file format, or such other formats as agreed to by the parties, to synchronize
sound content with text for use in then-current versions of Windows 9x, Windows
NT and Windows CE.  Prior to commencement of Development Work under this Section
1.4, the parties shall agree to a reasonable project statement that will guide
the direction and scope of the efforts.  The parties expect that this project
will result in a design document, a specification, and finally an implementation
of the specification, all of which shall be owned by Microsoft (except that any
Intellectual Property of Audible, preexisting as of the commencement of
Development Work under Section 1.3 or created by Audible outside of any
development work for Microsoft, applied in the performance of the work shall
continue to be the property of Audible for all purposes and shall only be deemed
licensed to Microsoft for the purposes of using the work product created under
this Section).

           ----------------------------
days of Microsoft requesting a port and providing file format specifications
Audible shall port Content from Audible's portfolio that Audible has rights to
port:

           (i)   to the ASF file format or, in the alternative, to any such
     single file format that Microsoft reasonably determines to utilize for
     Electronic Books content;

           (ii)  at Microsoft's request, to other file formats, provided
     Microsoft and Audible shall first agree upon reasonable compensation and
     terms for Audible performing such work; and

           (iii) at Microsoft's request, to future versions of the ASF file
     format released during the Term as mutually agreed to by the parties and,
     if mutually agreed, subject to

     Microsoft's payment of reasonable amounts to Audible to reimburse the costs
     of porting to such future versions;

In any case stated in (i), (ii) or (iii), as long as such file format reasonably
provides adequate security for Audible's Content and generally meets Audible's
business and technical needs, Audible shall port as much of its Content
portfolio as Microsoft requests and for which Microsoft agrees to pay NRE
Expenditures pursuant to Section 8.3.  Audible shall offer such ported Content
to End Users on substantially similar terms and conditions, and through
substantially similar distribution channels (including without limitation
audible.com), as Audible offers its other Content to End Users.  If Audible
determines in good faith that, given then-existing Audible resources, the
Microsoft requested porting cannot be finished in one hundred eighty (180)
days, then parties will discuss in good faith whether Microsoft will fund the
acquisition of additional resources as part of the NRE Expenditure
reimbursement, or whether the parties will extend the period for completing the
porting.

     (b)  Audible shall have no obligation to commence any Development Work
under this Section 1.4 until such time as Microsoft has selected the file format
under Section 1.4(a)(i) and provided Audible with specifications for the

Notwithstanding the foregoing sentence, all modifications, enhancements, and
improvements made to the source code by or for Microsoft shall be the sole and
exclusive property of Microsoft.  Microsoft agrees that the source code may not
be used to support a service bureau operation or for the benefit of any party
other than Microsoft or its sublicensees or assignees as allowed herein.
Furthermore, Microsoft agrees it shall only make reasonable number of copies of

the terms of this Agreement, provided that this Agreement is not terminated by
Microsoft pursuant to Section 3.1(b) prior to acceptance of any Customized
Software, or by Audible due to the default of Microsoft under the provisions of

pursuant to Section 4.1(d)(ii), the license shall continue in perpetuity
pursuant to the terms of this Agreement (without prejudice to Audible's
remedies, other than termination, for Microsoft breach).  In any event, existing

12.  INDEMNIFICATION
     ---------------

     12.1  Defense.  Each party (the "indemnifying party") shall, at its expense
           -------
and the other party's ("other party") request, defend any claim or action
brought against the other party, and the other party's subsidiaries, affiliates,
directors, officers, and employees, to the extent it is based upon a claim that,
(i) if true, would constitute a breach of the indemnifying party's warranties
under Section 11.1; (ii) is based on any product or service offered by the
indemnifying party, except to the extent arising from the contributions of the
other party; or (iii) is based on damage to property or injury to person caused
by the employees, permittees, or agents of the other party.  To the extent the
other party requests that the indemnifying party defend such claim, the party
requesting indemnification shall (i) provide the indemnifying party reasonably
prompt notice in writing of any such claim or action and permit the indemnifying
party, through counsel mutually acceptable to both parties, to answer and defend
such claim or action; and (ii) provide the indemnifying party information,
assistance and authority, at the indemnifying party's expense, to help the
indemnifying party to defend such claim or action.  In such event, the other
party will have the right to employ separate counsel at its own cost and
participate in the defense of any claim or action which the indemnifying party
is defending. The indemnifying party may not settle any claim or action under
this Section 12 on the other party's behalf without first obtaining the written
consent of the other party, which permission will not be unreasonably withheld
or delayed.

     12.2  Indemnity.  Regardless of whether the other party requests the
           ---------
indemnifying party to defend, the indemnifying party will indemnify and hold the
other party harmless from and against any damages finally awarded against the
other party or agreed pursuant to a settlement, and any costs and fees
(including without limitation, attorneys' fees other than fees for separate
counsel under Section 12.1) reasonably incurred by the other party that are
attributable to such a claim or action; provided, however, that:

     (i)   the indemnifying party will not be responsible for any settlement
           made by the other party without the indemnifying party's written
           permission, which permission will not be unreasonably withheld or
           delayed,

     (ii)  if the indemnifying party has replaced or corrected infringing
           materials, pursuant to Section 12.4, its indemnity obligation will in
           no event include the damages accruing as a result of the other
           party's failure to adopt, use and distribute (on a prospective basis
           only) such replacement or corrected version as soon as reasonably
           possible

     (iii) if the indemnifying party is defending a claim pursuant to the other
           party's request, and if the other party unreasonably withholds
           consent to a settlement proposed by the indemnifying party, the
           maximum amount that the indemnifying party will be responsible for
           shall be the amount payable under such settlement plus any costs and
           fees that the other party would have incurred in connection with such
           claim if it had been so settled.

     12.3  Publicity Regarding Settlement.  In the event the other party and the
           ------------------- ----------
indemnifying party agree to settle a claim or action, each party agrees not to
publicize the settlement without first obtaining the written permission of the
other party to this Agreement, which permission will not be unreasonably
withheld.

     12.4  Duty to Correct.  Should Audible's Client Software or Customized
           ---------------
Software ("Audible Infringing Materials"), or Microsoft's information, software
and tools provided to Audible under Section 2 or software tools licensed under
Section 4.3 ("Microsoft Infringing Materials"), or any portion thereof, be held
to constitute an infringement in breach of the warranties under Section 11.1 and
use as contemplated by this Agreement be enjoined, the providing party shall
notify the other party and immediately, at the expense of the providing party:
(i) procure for the other party the right to continue use of such Infringing
Materials or portion thereof, as applicable, as licensed in this Agreement; or
(ii) replace or modify the Infringing Materials or portion thereof with a
version that is non-infringing, with equivalent functionality in all material
respects.

     12.5  THIS SECTION STATES THE ENTIRE LIABILITY OF THE PARTIES TO EACH OTHER
WITH RESPECT TO THIRD PARTY CLAIMS FOR INFRINGEMENT OR MISAPPROPRIATION.

13.  LIABILITY, DAMAGES AND DISCLAIMERS
     ----------------------------------

to the infringement or misappropriation of the intellectual property or
confidential information of a party, IN THE EVENT EITHER PARTY IS FOUND LIABLE
TO THE OTHER FOR ANY MATTER RELATING TO OR ARISING FROM THE TRANSACTIONS

THEREFOR SHALL NOT EXCEED THE GREATER OF ONE MILLION DOLLARS OR TWICE THE AMOUNT
PAID BY MICROSOFT HEREUNDER; PROVIDED THAT THIS LIMITATION DOES NOT APPLY TO
OBLIGATIONS ARISING UNDER SECTION 12 OR SECTION 15.  THE LIMITATION IN THIS
SECTION IS A MATERIAL TERM IN THE PARTIES' AGREEMENT.

third party indemnification under this Agreement and except for claims relating
to the infringement or misappropriation of the intellectual property or
disclosure of confidential information of a party, NEITHER PARTY SHALL BE LIABLE
TO THE OTHER FOR ANY: (A) SPECIAL, INDIRECT, INCIDENTAL, PUNITIVE, OR

           ----------
DAMAGES IN EXCESS OF THE LIMITS PROVIDED FOR ABOVE.

14.  TERM
     ----

     14.1. Term.  The term of this Agreement shall commence on the Effective
           ----
Date and continue for an initial period of five years unless terminated earlier
pursuant to Section 14.2. hereof (the "Term").  This Agreement will be
automatically renewed for additional two year periods without notice unless
either party notifies the other party in writing at least 90 days prior to
expiration of the current term that it wishes not to renew this Agreement.

     14.2. Termination.  This Agreement shall terminate as provided below:
           -----------

           a.  Audible may, at its option, terminate this Agreement upon thirty
     (30) days' advance written notice to Microsoft in the event that Microsoft
     shall:  file for bankruptcy or suffer an involuntary bankruptcy that is not
     dismissed within ninety (90) days; or cease to conduct operations in the
     ordinary course of business; or fail to comply with any of its material
     obligations under this Agreement, which failure to comply shall be
     continuing for thirty (30) days following Microsoft's receipt of written
     notice from Audible stating the nature of Microsoft's non-compliance;

           b.  Microsoft may, at its option, terminate this Agreement upon
     thirty (30) days' advance written notice to Audible in the event that
     Audible shall: file for bankruptcy or suffer an involuntary bankruptcy that
     is not dismissed within ninety (90) days; or cease to conduct operations in
     the ordinary course of business; or fail to comply with any of its
     obligations under this Agreement, which failure to comply shall be
     continuing for thirty (30) days following Audible's receipt of written
     notice from Microsoft stating the nature of Audible's non-compliance.

     14.3. Continuing Liability.  The notification by either party of its
           --------------------
intent to terminate this Agreement does not relieve either party of any
obligations which have accrued under the terms and conditions of this Agreement,
inclusive of those terms and conditions which extend beyond the date of
termination.

     14.4  Effect of Termination.  Upon termination of this Agreement for any
           ---------------------
reason, the rights and obligations hereunder (except obligations for payments)
shall terminate, except that the provisions relating to license rights (to the
extent indicated in Section 4.2 above and provided Microsoft has paid to Audible
all fees payable under this Agreement), proprietary rights, confidentiality, and
indemnification shall remain in effect.  Upon a request by any party hereto,
confidential information of one party in the possession of the other shall be
returned except to the

extent necessary for the receiving party to continue exercising its rights after
the termination or expiration of this Agreement or to protect its legal rights
hereunder. Termination or expiration shall not effect the confidential nature of
such information.

15.  CONFIDENTIALITY
     ---------------

     15.1  Obligations.  The information and software (including CODECs, source
           -----------
code and documentation therefor) exchanged by the parties hereunder, including
the terms and conditions hereof, shall be subject to the Non-Disclosure
Agreement ("NDA") between the parties dated June 5, 1998, which is attached
hereto as Exhibit B.  For purposes of this Agreement such NDA shall be read as
(i) applying to information and software disclosed by the parties during the
Term in connection with the transactions contemplated herein, and (ii) with
respect to any particular information, having a term that survives as long as
the applicable information (including without limitation the source code of
either party) remains within the definition of Confidential Information.

     15.2  Intellectual Property.  Notwithstanding the above, the parties agree
           ---------------------
that whether or not intellectual property of the parties (including copyrighted
works) is disclosed in confidence, the intellectual property rights of the
parties shall remain in effect in accordance with the laws applicable to the
intellectual property in question. Nothing in this Section is intended to affect
the understandings of the parties elsewhere in this Agreement with respect to
ownership and use of intellectual property.

16.  [* * *]

     16.1  Microsoft.  Microsoft hereby agrees that, during the Term, [* * *]
           ---------

     16.2  Audible.  For as long as Microsoft has made the payments under
           -------
Sections 7.1 and 7.2 above, Audible hereby agrees that, during the Term, [* *
*].

     16.3  General.  Each party agrees that, in addition to other remedies
           -------
provided at law or in equity, upon a breach by such party of the covenant
contained in this Section 16, the other party shall be entitled to an injunction
against the breaching party, and any third parties in concert with the breaching
party, prohibiting further breach of the covenant contained herein.  The parties
agree that it is impossible to measure in money the damages that may accrue to
the nonbreaching party by reason of the breaching party's failure to obey the
covenant stated above.  Therefore, in the event of a breach or a threatened
breach by a party of the covenant in this Section 16, the parties agree that
such covenant may be enforced by a court of competent jurisdiction by a decree
for specific performance, in addition to other remedies nonbreaching party may
have.

     EACH PARTY HAS CONSULTED WITH COUNSEL, HAS READ THIS SECTION 16, AND AGREES
THAT THE CONSIDERATION PROVIDED HEREUNDER IS FAIR AND REASONABLE AND FURTHER
AGREES THAT [* * *] CONTEMPLATED IN THIS SECTION 16 ARE LIKEWISE FAIR AND
REASONABLE.

17.  GENERAL PROVISIONS
     ------------------

     17.1  Entire Agreement.  This Agreement and its schedules constitute the
           ----------------
entire agreement of the parties on the subject matter of this Agreement and
supersedes all prior agreements and understandings which may exist between the
parties, with respect to the subject matter hereof.  All amendments to this
Agreement must be in writing and signed by both parties.

     17.2  Assignment. Neither party may assign or transfer this Agreement or
           ----------
any rights granted to it hereunder without the prior written consent of the
other party, which consent shall not be unreasonably withheld or delayed. For
the purposes of this Agreement, a merger, consolidation, or other corporate
reorganization, or a transfer or sale of a controlling interest in a party's
stock (excluding such transactions with existing shareholders, transfers to
relatives by operation of law, or sale of securities in the public market, none
of which result in a new single entity or affiliated group of entities gaining
control of such party), or of all or substantially all of its assets
(collectively, a "Corporate Transfer") shall be deemed to be an assignment.

           (a) In the event Microsoft does not consent to a Corporate Transfer
or consents to a Corporate Transfer with conditions that are not acceptable to
Audible, and if Audible wishes to pursue the Corporate Transfer, then Microsoft
may terminate this Agreement (except for the provisions that survive as stated
elsewhere in this Agreement) as its sole remedy and Audible may continue with
the proposed Corporate Transfer. Such termination shall not result in any
liability from one party to the other except for amounts that were due and
payable on the date of termination. Subject to the preceding two sentences, this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their successors and assigns.

           (b) (i)  If, at any time during which Microsoft holds [ *** ] rights
under Section 7, Microsoft shall have the right of first negotiation on any
Corporate Transfer as follows:  If Audible receives an unsolicited proposal from
a third party (a "Solicitor") that Audible wishes to pursue (except during the
six (6) month period set forth in the sixth sentence below), or Audible
determines to solicit proposals or otherwise enter into discussions that would
result in a Corporate Transfer, Audible shall give written notice to Microsoft
of such occurrence (a "Corporate Transfer Notice").  Microsoft shall have seven
(7) days after receipt of the Corporate Transfer Notice to provide notice to
Audible in writing (a "Negotiation Notice") of its desire to negotiate in good
faith with Audible regarding a Corporate Transfer involving Microsoft.  If
Microsoft does not deliver such Negotiation Notice within 7 days of receipt
receiving the Corporate Transfer Notice, Audible will be free to negotiate with
any third party or parties regarding a Corporate Transfer.  If Microsoft
delivers a Negotiation Notice to Audible within 7 days of Microsoft receiving
the Corporate Transfer Notice, then (A) Audible will furnish to Microsoft such
relevant and pertinent information about Audible as may be appropriate to enable
Microsoft to engage in good faith negotiations, and (B) the parties will
negotiate exclusively in good faith regarding a Corporate Transfer until no
later than 21 days from the date Microsoft received the Corporate Transfer
Notice.  If, after 21 days, the parties cannot come to terms regarding a
Corporate Transfer of Audible, Audible will be free to negotiate with any third
party or parties regarding a Corporate Transfer.  If a definitive agreement for
a Corporate Transfer has not been entered into by Audible and any such third
party

or parties within six (6) months from the date of a Negotiation Notice delivered
by Audible to Microsoft, then the right of first negotiation process described
above in this Section 17.2(b) will again apply as if no such original
Negotiation Notice had been delivered to Microsoft. No Corporate Transfer that
occurs in violation of the process outlined above shall be valid. If Audible
makes a Corporate Transfer to a third party purchaser in accordance with the
terms of this Section 17.2, this Section 17.2 shall not apply to that third
party purchaser, unless the purpose of the Corporate Transfer was to circumvent
or defeat this Section 17.2. Clause (A) of this subsection (i) will not require
Audible to disclose to Microsoft the name of the Solicitor, or the amount of any
proposal or offer from such Solicitor and the material terms thereof or such
other information as would be reasonably expected to allow Microsoft to derive
the identity of the Solicitor if such information is subject to a non-disclosure
agreement and such information has not been provided by Audible to any other
third party other than professional advisors of Audible.

               (ii) During any period in which the provisions of Section
17.2(b)(i) are effective and any representative or affiliate of Microsoft serves
as a member of the Board of Directors of Audible (the "Director"), the Director
shall not participate in any discussions, deliberations or proceedings of the
Board of Directors with respect to its consideration of any Corporate Transfer.

     17.3  Internal Dispute Resolution.  In the event of any problem, claim, or
           ---------------------------
dispute arising from, out of, or based upon this Agreement, or the business
relationship between the parties, the aggrieved party shall promptly notify the
other party of the existence of the problem, claim, or dispute, and such other
party shall promptly undertake all reasonable efforts to resolve the matter,
including but not limited to, submitting such problem, claim or dispute for
resolution to a Manager of each party.  The Managers shall make a good faith
effort to resolve the dispute as quickly as possible.  In the event that the
Managers cannot resolve such dispute within twenty (20) days the matter may at
the option of either party, be submitted for resolution to each party's chief
executive with overall responsibility for the subject matter in dispute for a
period of twenty (20) days.

     17.4  Governing Law.  This Agreement shall be governed by and construed in
           -------------
accordance with the law of the State of Washington applicable to contracts
between residents of the State of Washington, and entered into and performed
entirely in the State of Washington.  Any action instituted by either party
arising out of this Agreement shall only be brought, tried and resolved in the
State of Washington.

     17.5  Severability.  If any provision of this Agreement or the application
           ------------
thereof to any person or circumstances shall, for any reason and to any extent,
be void or unenforceable, the application of the remainder of this Agreement to
such person or circumstances and the application of such provision to other
persons or circumstances shall be interpreted so as best to reasonably reflect
the intent of the parties hereto.  The parties further agree to replace such
void or unenforceable provisions of this Agreement with valid and enforceable
provisions which will achieve, to the extent possible, the economic, business
and other purposes of the void or unenforceable provisions.

     17.6. Relationship.  Nothing in this Agreement or in the activities
           ------------
contemplated by the parties pursuant to this Agreement shall be deemed to create
an agency, partnership, employment or joint venture relationship between the
parties.  Each party shall be deemed to be acting solely on its own behalf and,
except as expressly stated, has no authority to pledge the credit of, or incur
obligations or perform any acts or make any statements on behalf of, the other
party.  Neither arty shall represent to any person or permit any person to act
upon the belief that it has any such authority from the other party.  Neither
party's officers or employees, agents or contractors shall be deemed officers,
employees, agents or contractors of the other party for any purpose.

this Agreement, both parties may announce and/or confirm the existence of this

entity provided that the parties agree on the content, and date of the
announcement, and venue and vehicle for the announcement.

     17.8. No Waiver.  No waiver of any breach of the Agreement shall be deemed
           ---------
to be a waiver of any subsequent breach.

     17.9  Force Majeure.  Neither party will be liable for any failure or delay
           --------------
in its performance under this Agreement due to causes, including, but not
limited to, and act of God, an act of civil or military authority, fire,
epidemic, flood, earthquake, riot, war, sabotage, labor shortage or dispute, and
governmental action, which are beyond its reasonable control; provided that the
delayed party:  (a) gives the other party written notice of such cause promptly,
and in any event within 15 days of discovery thereof; and (b) uses its
reasonable efforts to correct such failure or delay in its performance.

     17.10 Attorneys' Fees.  A prevailing party in an action to enforce this
           ---------------
Agreement shall have the right to collect from the other its reasonable expenses
incurred in enforcing this Agreement including attorneys' fees.

           -------------------------
the parties hereto, shall be deemed to have been drafted by both parties, and
the language hereof shall be construed neutrally and not for or against any
party.  Where appropriate the singular shall include the plural.  The headings
of this Agreement are only for convenience and not intended to convey any
substantive meaning. In the event of a conflict between the provisions of the
Agreement and the provisions of any exhibit, the provisions of the exhibits

Content under DRM.  Audible shall provide such assistance [ *** ].

4.   DRM Implementation.
     ------------------

     4.1  Utilization of DRM.  Audible shall implement DRM on a non-exclusive
          ------------------
basis in the operation of Audible.com as soon as commercially reasonable after
DRM is made available to Audible for the purpose of licensing Audible Content

to Electronic Book customers.  Microsoft shall provide the client software to be

          ---------------
the anticipated development may be completed within the NRE Expenditure limit of

     5.1  Nonexclusive Clearinghouse.  (a) Microsoft anticipates that, in
          --------------------------
conjunction with the distribution of DRM, it will license other entities
("Clearinghouses") to confirm that text, audio, software, or other content
encoded under DRM is properly licensed for End User use.  In that event,
Microsoft shall designate Audible as a nonexclusive Clearinghouse as soon as
such designations are available, on terms at least as favorable as any similarly
situated Clearinghouse, including a license to DRM software necessary for
operating as a Clearinghouse.  For that purpose, Microsoft hereby agrees to
deliver to Audible [ *** ], for a period of two years from the commercial
release of DRM, any Microsoft Product for securing electronic audio content with
DRM.  Microsoft shall provide a number of copies of such Microsoft Products
sufficient for the operation of Audible.com.  Audible's use of each such
Microsoft Product shall be subject to the standard Microsoft end user license
agreement included therewith, provided that such licenses must be perpetual and
must be [ *** ] during the two-year period after commercial release of DRM.
Microsoft shall refer any content providers wishing to secure their Spoken Word
Audio content under DRM to Audible (on a nonexclusive basis).  Microsoft
anticipates that it will provide Clearinghouses with a secure publishing toolkit
to redistribute to content providers, to assist in the encoding of content
compatible with DRM or will encourage content providers to license such secure
publishing toolkit from Audible. For a period of two (2) years from the
commercial release of DRM, Microsoft agrees that Audible will be a preferred
Clearinghouse and with regard to major financial terms be treated on a Most
Favored Nations (MFN) basis by Microsoft in the field of secure audio
distribution over the Internet.

          (b) After the expiration of said two-year period, Audible shall have
the option to continue as a Clearinghouse, and to acquire DRM-related Microsoft
Products as described above, on terms and pricing no less favorable than the
terms and pricing made available by Microsoft to any third party receiving a DRM
license and Clearinghouse designation.

     5.2  Transaction Fees.  Audible reserves the right to charge a fee to
          ----------------
content providers or End Users each time Audible, acting as a Clearinghouse,
confirms the licensing of DRM encoded content.  In such event, Audible shall
share any such transaction fee with Microsoft as follows.  Microsoft shall not
receive transaction fees under this Agreement on any given Audible revenues to
the extent Audible pays Microsoft transaction fees thereon under the Development
Agreement.

          5.2.1  in all cases not covered by Section 5.2.2, the greater of [ ***
] of Net Transaction Revenues or [ *** ] of Gross Transaction Revenues, unless
otherwise provided below;

          5.2.2  for each year that Microsoft chooses to exercise its option for
exclusive access rights pursuant to Section 7 of the Development Agreement, the
greater of [ *** ] of Net Transaction Revenues or [ *** ] of Gross Transaction
Revenues.

     5.3  Payments.  Payments of royalties owed by Audible to Microsoft for a
          --------
given calendar month shall be made within thirty (30) days from the end of the
month, accompanied by documentation indicating the calculation of the royalties
due.

     5.4  Audit Provisions. During the term of this Agreement, Audible agrees to
          ----------------
keep all usual and proper records and books of account and all usual and proper
entries relating to Gross Transaction Revenues and Net Transaction Revenues.
Microsoft may cause an audit to be made of the applicable records in order to
verify invoices or other statements by Audible, and prompt adjustment shall be
made to compensate for any errors or omissions disclosed by such audit.  Any
such audit shall be conducted by an independent certified public accountant
selected by Microsoft (other than on a contingent-fee basis) and shall be
conducted during regular business hours at Audible's offices and in such a
manner as not to interfere with Audible's normal business activities.  Any such
audit shall be paid for by Microsoft unless material discrepancies are
disclosed.  "Material" shall mean a discrepancy amounting to at least five
percent (5%) of the amount that should have been reported.  If material
discrepancies are disclosed, Audible agrees to pay Microsoft for the reasonable
costs associated with the audit. Audible shall pay interest of one percent (1%)
per month on all moneys due Microsoft to remedy material discrepancies more than
six (6) months old at time of audit.

     5.5  No Set Off.  The payments due under this Agreement are not subject to
          ----------
any right of set-off except in the event of a good faith payment dispute.

6.   Nondisclosure; Public Statements.
     --------------------------------

     6.1  Nondisclosure.
          -------------

the definition of Confidential Information.

     (b)  Notwithstanding the above, the parties agree that whether or not
intellectual property of the parties (including copyrighted works) is disclosed
in confidence, the intellectual property rights of the parties shall remain in
effect in accordance with the laws applicable to the intellectual property in
question.  Nothing in this Section is intended to affect the understandings of
the parties elsewhere in this Agreement with respect to ownership and use of
intellectual property.

     6.2  Press.  Microsoft and Audible agree that they will publicly announce
          -----
the cooperation of the parties with respect to rights management technology and

     formats, which Diamond desires to be incorporated into the software. The
     placement, form and format of any such branding shall be as mutually agreed

     doing any other type of branding on its products and services.  In
     addition, Audible agrees to feature prominently the Rio II product on

     mutually agree to.  The web site shall refer visitors to audible.com who

     Products which are manufactured by or for Diamond pursuant to technical
     specifications to be agreed to by the parties

     3.2  By Diamond.
          ----------


          (a) Branding and Integration.  Diamond agrees that, commencing with

     the Rio II product release, by the Anticipated Launch Date it will
     Integrate the Rio Products to make them AudibleReady, and will prominently
     brand the Rio Products with the AudibleReady logo (which logo will be
     provided by Audible to Diamond) on (i) the Rio II units (as described
     below), (ii) the box in which the Rio II is distributed, (iii) Diamond's
     in-box materials (e.g., manuals, user guides, inserts, etc.), and (iv) as
     appropriate, Rio II-related marketing materials (e.g., print advertising,
     Diamond's web site, banner advertisements).  The placement, form and format
     of such branding shall be as mutually agreed upon by the parties; however,
     Diamond agrees that it shall include the AudibleReady logo at least on
     either the back and/or side of Rio II and that such branding shall be

     Anticipated Launch Date, the parties hereby agree to continue to work
     in

by Diamond, Diamond agrees to use its good faith efforts to promote and seek to
Integrate Audible technology and AudibleReady branding in such products, and to
participate in Audible co-marketing programs with respect to such products. Such
efforts will include, without limitation, introducing Audible to existing and
prospective OEMs of Diamond. Audible acknowledges and agrees that the decision
whether to include Audible technology, AudibleReady branding and to participate
in Audible co-marketing programs will be in the reasonable discretion of Diamond
and its OEMs. Third party OEMs Integrating Audible's technology in their
products must receive the necessary Intellectual Property licenses directly from

           (a) Each of Diamond and Audible each agree to hold in strictest
     confidence any information and material which is related to the other's

     than for the performance of this Agreement.  Both parties agree that
     proprietary and confidential information (whether or not marked as such)
     includes, without limitation, information related to research and
     development efforts, security data, CODEC information, software (in both

           (b) Diamond acknowledges that the Client Software, the Audible
     Software, and the Audible Firmware are valuable property of Audible
     containing trade secrets of Audible and that, in the course of the
     implementation of this Agreement, Diamond will become privy to information
     regarding the Client Software, the Audible Software, and the Audible
     Firmware that Audible regards as proprietary and confidential.  In this
     regard, Diamond agrees that neither Diamond nor its employees and agents
     shall communicate, disclose or in any manner convey any proprietary or
     confidential information regarding the Client Software, the Audible
     Software, or the Audible Firmware to any person, organization, company,

20 days of the receipt of a demand for arbitration.  If either party fails to
select an arbitrator within such twenty day period, the one (1) selected shall
act as sole arbitrator.  If two (2) arbitrators have been selected, the two (2)
arbitrators selected shall select a third within fifteen (15) days after their
selection.  If they fail to do so, the third arbitrator shall be selected by the
American Arbitration Association.  The arbitrators shall set a date of hearing
no later than sixty (60) days from the date all arbitrators have been selected
and shall enter a decision within thirty (30) days of the end of the proceeding.
The arbitration shall take place at a location to be agreed upon by the parties.
If the parties are unable to agree, the arbitrators shall select a location in
either New jersey, New York City, or California for the arbitration.  In any
such arbitration proceeding the arbitrators shall adopt and apply the provisions
of the Federal Rules of Civil Procedure relating to discovery so that each party
shall allow and may obtain discovery of any matter not privileged which is
relevant to the subject matter involved in the arbitration to the same extent as
if such arbitration were a civil action pending in a United States District
Court; provided, however, that each party shall be entitled to no more than four
       -----------------
(4) depositions upon oral examination.  The award of any arbitration shall be
final, conclusive and binding on the parties hereto.  The arbitrators may award
any legal or equitable remedy.  The arbitration award shall include an award of
attorneys' fees, in the amount of such fees, to the prevailing party.  Judgment
upon any arbitration award may be entered and enforced in any court of competent
jurisdiction.  Either party to an arbitration hereunder may bring an action for
injunctive relief against the other party if such action is necessary to
preserve jurisdiction of the arbitrators or to maintain status quo pending the
arbitrators decision.

     16.5  Severability.  If any provision of this Agreement or the application
           ------------
thereof to any person or circumstances shall, for any reason and to any extent,
be void or unenforceable, the application of the remainder of this Agreement to
such person or circumstances and the application of such provision to other
persons or circumstances shall be interpreted so as best to reasonably reflect
the intent of the parties hereto.  The parties further agree to replace such
void or unenforceable provisions of this Agreement with valid and enforceable
provisions that will achieve, to the extent possible, the economic, business and
other purposes of the void or unenforceable provisions.

     16.6 Relationship.  The parties agree that their relationship hereunder is
          ------------
that of independent contractors.  Nothing in this Agreement or in the activities
contemplated by the parties pursuant to this Agreement shall be deemed to create
an agency, partnership, employment or joint venture relationship between the
parties.  Each party shall be deemed to be acting solely
