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.

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.

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.

                   ------------------                                          
of powers conferred by statute, it is further provided:

          A.   Election of directors need not be by written ballot unless the 
By-Laws of the Corporation shall so provide. Except as otherwise provided in
this Amended and Restated Certificate of Incorporation or a certificate of
designation relating to the rights of the holders of any class or series of
Preferred Stock, voting separately by class or series, to elect additional
directors under specified circumstances, the number of directors of the
Corporation shall be as fixed from time to time by or pursuant to the By-Laws of
the Corporation. No director of the Corporation need be a stockholder of the

          B.   The Board of Directors shall be classified with respect to the
time for which they severally hold office into three separate classes, Class I,
Class II and Class III, which shall be as nearly equal in number as possible,
and shall be adjusted from time to time in the manner specified in the By-Laws
of the Corporation to maintain such proportionality.  Each intial director in
Class I shall hold office for a term expiring at the 2000 annual meeting of
stockholders.  Each initial director in Class II shall hold office initially for
a term expiring at the 2001 annual meeting of stockholders.  Each initial
director in Class III shall hold office for a term expiring at the 2002 annual
meeting of stockholders.  Notwithstanding the foregoing provisions of this
Article FIFTH, each director shall serve until such director's successor is duly
elected and qualified or until such director's earlier death, resignation or
removal.  At each annual meeting of stockholders, the successors to the class of
directors whose term expires at that meeting shall be elected to hold office for
a term expiring at the annual meeting of stockholders 

                                      -3-
<PAGE>
 
held in the third year following the year of their election and until their
successors have been duly elected and qualified or until any such director's
earlier death, resignation or removal.

          C.   The Board of Directors is expressly authorized to adopt, amend or
repeal the By-Laws of the Corporation.
 
          SIXTH.   Meetings of Stockholders.  Meetings of stockholders may be
                   ------------------------                                  
held within or without the State of Delaware, as the By-Laws of the Corporation
may provide.  Upon the closing of an underwritten initial public offering of the
Corporation's Common Stock pursuant to the effective registration statement
under the Securities Act of 1933, as amended, any action required or permitted
to be taken at any annual or special meeting of stockholders of the Corporation
may be taken only upon the vote of stockholders at an annual or special meeting
duly noticed and called in accordance with the General Corporation Law of the
State of Delaware and may not be taken by written consent of stockholders
without a meeting, unless such consent is unanimous.

          SEVENTH: Special Meetings of Stockholders.  Special meeting of
                   --------------------------------                     
stockholders may be called at any time by the Chairman of the Board, the
President, the Board of Directors, the holders of a majority of the outstanding
shares of the Corporation's capital stock and entitled to vote generally in the
election of directors.  Business transacted at any special meeting of
stockholders shall be limited to matters relating to the purpose or purposes
stated in the notice of meeting.

          EIGHTH.  Limitation on Liability.  No director of the Corporation
                   -----------------------                                 
shall be personally liable to the Corporation or to any stockholder of the
Corporation for monetary damages for breach of fiduciary dity as a director,
provided that this provision shall not limit the liability of a director (i) for
any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involved
intentional misconduct or a knowing violation of law, (iii) under Section 174 of
the General Corporation Law of Delaware, or (iv) for any transaction from which
the director derived an improper personal benefit.

          If the General Corporation Law of Delaware or any other statute of the
State of Delaware hereafter is amended to authorize the further elimination or
limitation of the liability of directors of the corporation, then the liability
of a director of the corporation shall be limited to the fullest extent
permitted by the statutes of the State of Delaware, as so amended, and such
elimination or limitation of liability shall be in addition to, and not in lieu
of, the limitation on the liability of a director provided by the foregoing
provisions of this Sixth Article.

          Any repeal of or amendment to this Sixth Article shall be prospective
only and shall not adversely affect any limitation on the liability of a
director of the corporation existing at the time of such repeal or amendment.

                                      -4-

          NINTH.   To the extent permitted by law, the Corporation shall fully
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding (whether
civil, criminal, administrative or investigative) by reason of the fact that
such person is or was a director or officer of the Corporation, or is or was
serving at the request of the Corporation as a director or officer of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding.

     To the extent permitted by law, the Corporation may fully indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (whether civil,
criminal, administrative or investigative) by reason of the fact that such
person is or was an employee or agent of the Corporation, or is or was serving
at the request of the Corporation as an employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding.

     The Corporation may advance expenses (including attorneys' fees) incurred
by a director or officer in advance of the final disposition of such action,
suit or proceeding upon the receipt of an undertaking by or on behalf of the
director or officer to repay such amount if it shall ultimately be determined
that such director or officer is not entitled to indemnification.  The
Corporation may advance expenses (including attorneys' fees) incurred by an
employee or agent in advance of the final disposition of such action, suit or
proceeding upon such terms and conditions, if any, as the Board of Directors
deems appropriate.

          TENTH.   The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Amended and Restated Certificate of
Incorporation, in the manner now or hereafter prescribed by statute and the
Certificate of Incorporation, and all rights conferred upon stockholders herein
are granted subject to this reservation.

     4.   This Amended and Restated Certificate of Incorporation was duly
adopted by the Board of Directors in accordance with Section 245 of the General
Corporation Law of the Sate of Delaware.

     5.   This Amended and Restated Certificate of Incorporation was duly
adopted by written consent of the stockholders in accordance with the applicable
provisions of Sections 228, 242 and 245 of the General Corporation Law of the
State of Delaware.

     1.1  Place of Meeting.  All meetings of stockholders shall be held at such
          -----------------                                                    
place within or without the State of Delaware as may be designated from time to
time by the Board of Directors or the President or, if not so designated, at the
registered office of the Company.

     1.2  Annual Meeting.  The annual meeting of stockholders for the election
          ---------------                                                     
of directors and for the transaction of such other business as may properly be
brought before the meeting shall be held at such date, time and place as may be
fixed by the Board of Directors or the President.  If this date shall fall upon
a legal holiday at the place of the meeting, then such meeting shall be held on
the next succeeding business day at the same hour.  If no annual meeting is held
in accordance with the foregoing provisions, the Board of Directors shall cause
the meeting to be held as soon thereafter as convenient.  If no annual meeting
is held in accordance with the foregoing provisions, a special meeting may be
held in lieu of the annual meting, and any action taken at that special meeting
shall have the same effect as if it had been taken at the annual meeting, and in
such case all references in these By-Laws to the annual meeting of the
stockholders shall be deemed to refer to such special meeting.

     1.3  Special Meetings.  Special meetings of stockholders may be called at
          -----------------                                                  
any time by the Chairman of the Board, the President, the Board of Directors or
the holders of a majority of the outstanding shares of the Company's capital
stock and entitled to vote generally in the election of directors.  Business
transacted at any special meeting of stockholders shall be limited to matters
relating to the purpose or purposes stated in the notice of meeting.

     1.4  Notice of Meetings.  Except as otherwise provided by law, written
          -------------------                                              
notice of each meeting of stockholders, whether annual or special, shall be
given not less than ten nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting.  The notices of all meetings
shall state the place, date and hour of the meeting.  The notice of a special
meeting shall state, in addition, the purpose or purposes for which the meeting
is called.  If mailed, notice is given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the Company.

Company shall prepare, at least 10 days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least 10 days prior to the
meeting, at a place within the city where the meeting is to be held.  The list
shall also be produced and kept at the time and

place of the meeting during the whole time of the meeting, and may be inspected
by any stockholder who is present.

     1.6  Quorum.  Except as otherwise provided by law, the Certificate of
          -------                                                         
Incorporation or these By-Laws, the holders of a majority of the shares of the
capital stock of the Company issued and outstanding and entitled to vote at the
meeting, present in person or represented by proxy, shall constitute a quorum
for the transaction of business.

     1.7  Adjournments.  Any meeting of stockholders may be adjourned to any
          ------------                                                      
other time and to any other place at which a meeting of stockholders may be held
under these By-Laws by the stockholders present or represented at the meeting
and entitled to vote, although less than a quorum, or, if no stockholder is
present, by any officer entitled to preside at or to act as Secretary of such
meeting.  It shall not be necessary to notify any stockholder of any adjournment
of less than 30 days if the time and place of the adjourned meeting are
announced at the meeting at which adjournment is taken, unless after the
adjournment a new record date is fixed for the adjourned meeting.  At the
adjourned meeting, the Company may transact any business which might have been
transacted at the original meeting.

    1.8   Voting and Proxies.  Each stockholder shall have one vote for each
          -------------------                                               
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
in the Certificate of Incorporation.  Each stockholder of record entitled to
vote at a meeting of stockholders, or to express consent or dissent to corporate
action in writing without a meeting, may vote or express such consent or dissent
in person or may authorize another person or persons to vote or act for him by
written proxy executed by the stockholder or his authorized agent and delivered
to the Secretary of the Company.  No such proxy shall be voted or acted upon
after three years from the date of its execution, unless the proxy expressly
provides for a longer period.

    1.9   Action at Meeting.  When a quorum is present at any meeting, the
          ------------------                                              
holders of a majority of the stock present or represented and voting on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of a majority of the
stock of that class present or represented and voting on a matter) shall decide
any matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these By-Laws.  Any election by stockholders shall be
determined by a plurality of the votes cast by the stockholders entitled to vote
at the election.

    1.10  Action without Meeting.  Upon the closing of an underwritten initial
          -----------------------                                             
public offering of the Company's Common Stock pursuant to the effective
registration statement under the Securities Act of 1933, as amended, any action
required or permitted to be taken at any annual or special meeting of
stockholders of the Company may be taken only upon the vote of stockholders at
an annual or special meeting duly noticed and called in accordance with the
General Corporation Law of the State of Delaware and may not be taken by written
consent of stockholders without a meeting, unless such consent is unanimous.

     1.11  Stockholder Nominations and Proposals.  (a)  No proposal for a
           -------------------------------------                         
stockholder vote (a "Stockholder Proposal") shall be submitted to the
stockholders of the Company unless the stockholder submitting such proposal (the
"Proponent") shall have filed a written notice setting forth with particularity
(i) the names and business addresses of the Proponent and all Persons (as such
term is defined in Section 3(a)(9) of the Securities Exchange Act of 1934, as
amended, (the "Exchange Act")) acting in concert with the Proponent; (ii) the
names and addresses of the Proponent and the Persons identified in clause (i),
as they appear on the Company's books (if they so appear); (iii) the class and
number of shares of the Company beneficially owned by the Proponent and the
Persons identified in clause (i); (iv) a description of the Stockholder Proposal
containing all information material thereto; (v) a description of all
arrangements or understandings between the Proponent and any other Persons
(including the names of such other Persons) in connection with the Stockholder
Proposal and any material interest of the Proponent or such Persons in such
Stockholder Proposal and (vi) such other information as the Board of Directors
reasonably determines is necessary or appropriate to enable the Board of
Directors and stockholders to consider the Stockholder Proposal.  Upon receipt
of the Stockholder Proposal and prior to the stockholders' meeting at which such
Stockholder Proposal will be considered, if the Board of Directors or a
designated committee or the officer who will preside at the meeting of the
stockholders determines that the information provided in a Stockholder Proposal
does not satisfy the requirements of this Section 1.11 or is otherwise not in
accordance with applicable law, the Secretary of the Company shall promptly
notify the Proponent of the deficiency in the notice.  Such Proponent shall have
the opportunity to cure the deficiency by providing additional information to
the Secretary within the period of time, not to exceed five days from the date
such deficiency notice is given to the Proponent, determined by the Board of
Directors, such committee or such officer.  If the deficiency is not cured
within such period, or if the Board of Directors, such committee or such officer
determines that the additional information provided by the Proponent, together
with the information previously provided, does not satisfy the requirements of
this Section 1.11 or is otherwise not in accordance with applicable law, then
such Stockholder Proposal shall not be presented for action at the stockholders'
meeting in question.

     (b)   Only persons who are selected and recommended by the Board of
Directors or the nominating committee thereof, or who are nominated by the
stockholders in accordance with the procedures set forth in this Section 1.11,
shall be eligible for election or qualified to serve as directors. Nominations
of individuals for election to the Board of Directors at any annual meeting or
special meeting of the stockholders at which directors are to be elected may be
made by any stockholder of the Company entitled to vote for the election of
directors at that meeting by compliance with the procedures set forth in this
Section 1.11 except as may be otherwise provided in the Certificate of
Incorporation with respect to the right of holders of Preferred Stock of the
Company to nominate and elect a specified number of directors in certain
circumstances. Nominations by stockholders shall be made by written notice (a
"Nomination Notice"), which shall set forth (i) as to each individual nominated
(A) the name, date of birth, business address and residence address of such
nominee; (B) the business experience during the past five years of such nominee,
including his or her principal occupations or employment during such period, the
name and principal business of any Company or other organization in which such
occupations and employment were carried on, and such other information as to the
nature of his or her responsibilities and the level of professional competence
as may be sufficient to permit assessment of his or her prior business
experience; (C) whether the nominee is or has ever been at any time a director,
officer or owner of 5% or more of any class of capital stock, partnership
interests or other 

                                      -6-
<PAGE>
 
equity interest of any Company, partnership or other entity; (D) any
directorships held by such nominee in any company with a class of securities
registered pursuant to section 12 of the Exchange Act or subject to the
requirements of section 15(d) of the Exchange Act or any company registered as
an investment company under the Investment Company Act of 1940, as amended; (E)
whether, in the last five years, such nominee has been convicted in a criminal
proceeding or has been subject to a judgment, order, finding or decree of any
federal, state or other governmental entity, concerning any violation of
federal, state, or other law, or any proceeding in bankruptcy, which conviction,
judgment, order, finding, decree or proceeding may be material to the evaluation
of the ability or integrity of the nominee; and (F) any other information
relating to the nominee that would be required to be disclosed in a proxy
statement or other filings required to be made in connection with solicitations
of proxies for election of directors pursuant to section 14 of the Exchange Act,
and the rules and regulations promulgated thereunder; and (ii) as to the person
submitting the Nomination Notice and any Person acting in concert with such
Person, (w) the name and business address of such person and Persons, (x) the
name and business address of such person and Persons as they appear on the books
of the Company (if they so appear); (y) the class and number of shares of the
Company which are beneficially owned by such person and Persons, and (z) any
other information relating to such stockholder that would be required to be
disclosed in a proxy statement or other filings required to be made in
connection with solicitations of proxies for election of directors pursuant to
section 14 of the Exchange Act and the rules and regulations promulgated
thereunder. A written consent to being named in a proxy statement as a nominee,
and to serve as a director if elected, signed by the nominee, shall be filed
with any Nomination Notice. If the presiding officer at any stockholders'
meeting determines that a nomination was not made in accordance with the
procedures prescribed by these By-laws, he shall so declare to the meeting and
the defective nomination shall be disregarded.

     (c)  Nomination Notices and Stockholder Proposals must be delivered to the
Secretary at the principal executive office of the Company or mailed and
received at the principal executive offices of the Company (a) in the case of
any annual meeting, not less than 60 days nor more than 90 days prior to the
anniversary date of the immediately preceding annual meeting of stockholders;
provided, however, that (i) in the event that the annual meeting is called for a
date that is not within 30 days before or 60 days after such anniversary date,
or (ii) in the case of the annual meeting of stockholders held during the 1999
fiscal year of the Company, notice by the stockholder in order to be timely must
be so received no later than the close of business on the tenth day following
the day on which notice of the date of the annual meeting was mailed or public
disclosure of the date of the annual meeting was made, whichever first occurs;
and (b) in the case of a special meeting of stockholders called for the purpose
of electing directors, not later than the close of business on the tenth day
following the day on which notice of the date of the special meeting was mailed
or public disclosure of the date of the special meeting was made, whichever
first occurs.

of the powers of the Company except as otherwise provided by law, the

Board of Directors, the remaining directors, except as otherwise provided by
law, may exercise the powers of the full Board until the vacancy is filled.

    2.2   Number; Election and Qualification.  The number of directors which
          -----------------------------------                               
shall constitute the whole Board of Directors shall be determined by resolution
of the Board of Directors, but in no event shall be less than one.  The number
of directors may be decreased at any time and from time to time by a majority of
the directors then in office, but only to eliminate vacancies existing by reason
of the death, resignation, removal or expiration of the term of one of more
directors.  Unless otherwise provided in the Certificate of Incorporation, the
Board of Directors shall divide the directors into three classes, which shall be
as equal in number as possible; and, when the number of directors is changed,
shall determine the class or classes to which the increased or decreased number

and subject to the provisions of the General Company Law of the State of
Delaware, shall have and may exercise all the powers and authority of the Board
of Directors in the management of the business and affairs of the Company and

require it. Each such committee shall keep minutes and make such reports as the
Board of Directors may from time to time request. Except as the Board of

or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding by or in the right of the Company to procure a
judgment in its favor by reason of the fact that such person is or was a
director or officer of the Company, or is or was serving at the request of the
Company as a director of officer of another Company, partnership, joint venture,
trust, employee benefit plan or other enterprise, against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection

good faith and in a manner which such person reasonably believed to be in or not
opposed to the best interest of the Company.  No such indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the Company unless and only to the extent that the

that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which such court shall deem proper.

     (b) The Company may indemnify any person who was or is a party or is

of the Company, or is or was serving at the request of the Company as an
employee or agent of another Company, partnership, joint venture, trust,
employee benefit plan or other enterprise, against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
with the defense or settlement of such action or suit if such person acted in
good faith and in a manner which such person reasonably believed to be in or not
opposed to the best interests of the Company.  No such indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the Company unless and only to the extent that the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which such court shall deem proper.

     5.3  Authorization of Indemnification.   Any indemnification under this
          --------------------------------                                  
Article 5 shall be made by the Company only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because such person or persons have met the
applicable standard of conduct set forth in Sections 5.1 and 

                                      -15-

5.2 hereof. Such determination shall be made (1) by a majority vote of the
directors who are not parties to such action, suit or proceeding, even though
less than a quorum, or (2) if there are no such directors, or if such directors
so direct, by independent legal counsel in a written opinion, or (3) by the
stockholders.

     5.4  Advancement of Expenses.  The Company may advance expenses (including
          -----------------------                                              
attorneys' fees) incurred by a director or officer in advance of the final
disposition of such action, suit or proceeding upon the receipt of an
undertaking by or on behalf of the director of officer to repay such amount if
it shall ultimately be determined that such director or officer is not entitled
to indemnification.  The Company may advance expenses (including attorneys'
fees) incurred by an employee or agent in advance of the final disposition of
such action, suit or proceeding upon such terms and conditions, if any, as the
Board of Directors deems appropriate.

     5.5  Claims.  If a claim for indemnification or payment of expenses under
          ------                                                              
this Article 5 is not paid with 60 days after a written claim therefor is
received by the Company, the claimant may recover the unpaid amount of such
claim and, if successful in whole or in part, shall be entitled to be paid the
expense of prosecuting the claim.  In any such action, the Company shall have
the burden of proving that the claimant was not entitled to the requested
indemnification or payment of expenses under applicable law.

     5.6  Insurance.  The Company shall have power to purchase and maintain
          ---------                                                        
insurance on behalf of any person who is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Company as
a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the Company would have the power to indemnify him against
such liability under the provisions of this Article.

of any Update, such Update shall be deemed to be part of the Audible Software
for Windows CE for all purposes of this Agreement.  If Microsoft secures
unrestricted source code rights by exercising its option under Section
4.1(d)(ii), and if Microsoft then creates a derivative work of the Audible
Software for Windows CE with substantially similar functionality but which is
not enabled to access Audible Content, or in which access to Audible Content is
afforded less than a parity position when compared to any other Spoken Word
Audio, then Audible shall have the right, upon written notice to Microsoft, to
discontinue its obligation to provide Updates to Microsoft under this Section
3.2.

     3.3   Ongoing Assistance.  Throughout the term, upon Microsoft's request,
           ------------------                                                 
Audible shall provide reasonable error correction and development assistance

playback of Audible Content.

          -------------------                                             
documentation (collectively, the "source code") for the Customized Software as
stated in Section 4.1(a)(i) above shall be subject to the following terms and
conditions.  Such source code shall only be used under strict confidentiality
obligations for purposes of:

          (i)  maintaining, fixing and enhancing the Customized Software for
integration with Microsoft Products, while maintaining substantially similar
functionality of the Customized Software, and

          (ii) meeting Microsoft's contractual obligations to third-party

     (d)  Notwithstanding the foregoing, Microsoft may exercise the license
rights granted hereunder in source code for the Audible Software for Windows CE
free of the scope of use restrictions stated in Section 4.1(c)(i) and (ii), if
and only if:  (i) Audible Software for Windows CE is included in a commercial

Audible Software for Windows CE in such versions of Windows CE, or (ii)
Microsoft pays Audible a mutually agreed, one-time license fee [* * *].

should such browsing software have a "Favorites" folder which includes default
URLs for sites other than Microsoft sites, the URL for audible.com shall be
included as a default URL in such "Favorites" folder; and

          (ii) The obligation regarding promotion and branding set forth in
Section 5.3.

     (f)  Microsoft hereby agrees that the source code and any copies thereof,
as well as all modifications and improvements made to the source code by or for
Audible, are and remain the sole and exclusive property of Audible.
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 source code in accordance with Microsoft customary product development
practices.  Microsoft agrees that it will not (and it will not allow others to)
alter or remove any copyright, trade secret, patent, proprietary and/or other
legal notices contained on or in copies of the source.

     4.2  The license rights under Section 4.1 shall be perpetual pursuant to
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
this Agreement.  (For avoidance of doubt, if Microsoft does not accept only one
of either the Audible Media Player Software or the Audible Software for Windows
CE, then Microsoft's license shall survive only with respect to the accepted
software.)  If Microsoft terminates this Agreement pursuant to Section 3.1(b)
without accepting any Customized Software, the license shall terminate upon
termination of this Agreement.  If Microsoft has not secured unrestricted source
code rights pursuant to Section 4.1(d)(ii), the license shall terminate with
respect to each Microsoft Product upon the release of a major new version of
said Microsoft Product (i.e., a product with a higher version number to the left
of the decimal point) at least six (6) months after termination of this
Agreement.  However, if Microsoft has secured unrestricted source code rights
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
sublicenses granted by Microsoft as of the date of notice of termination shall
survive termination for the then-current term of such sublicenses.

     4.3  Sublicenses.  Sublicenses granted by Microsoft to licensees shall
          -----------                                                      
comport with the terms of this Agreement and include reasonable terms and
conditions to protect Audible's Intellectual Property and Confidential
Information in the same manner as Microsoft protects its own Intellectual
Property and Confidential Information, and to limit liability to Audible in the
same manner as Microsoft limits its own liability vis a vis the third parties.

          --------------------------------------

Microsoft's standard end user license agreement included therewith shall govern

option referenced in Section 7.2 above, Microsoft's right to exercise any
subsequent option referred in Section 7.2 shall be waived.  Notwithstanding
anything contained herein to the contrary, the rights and options granted
pursuant to this Section 7 shall be subject in all cases to such [ *** ]
restrictions as may be applicable to Audible's underlying rights to use the
Content.

              (ii) in months [* * *], to the greater of [* * *]% of Net Content
          Revenues or [ *** ] of Gross Content Revenues.

    8.2   Duration and Payment.  In all cases, these royalties will be paid
          --------------------                                             
throughout the Term of the Agreement and cease upon the expiration or
termination of the Agreement.  Payments of royalties owed by Audible to
Microsoft shall be made on a yearly basis within 30 days of each anniversary
date of the Effective Date, accompanied by documentation for the calculation of
the royalties due.

     8.3  Development Payments.  Microsoft shall pay Audible a one-time fee in
          --------------------                                                
the amount of $200,000 for the project identified in Section 1.2.  Microsoft
acknowledges completion of this project and acceptance in February 1999.
Microsoft shall reimburse Audible the amount of its NRE Expenditures up to a sum
not to exceed $[* * *] for each of the projects identified in Section 1.3.  Such
NRE funds shall be non-refundable.  Audible shall present to Microsoft an
estimate of the expected NRE Expenditures at the commencement of each project
and shall invoice Microsoft for such sums as are actually incurred on a monthly
basis.  If parties agree that Audible will do further development work to
improve the integration of the Client Software with Windows generally, or with
Windows CE-based platforms or successor products, including any platforms and
upgrades of such products, or in connection with other development efforts, then
the parties will negotiate in good faith to agree on the appropriate amount of
Microsoft's compensation to Audible for such work.

     8.4  Audit Provisions.  Audible shall keep records in accordance with
          ----------------                                                
generally accepted accounting principles and in sufficient detail to permit a
review of the accuracy of royalty payments to Microsoft and cost reimbursements
claimed by Audible under this Agreement.  Such records shall be kept for three
years following the payment date for royalties.  Upon Microsoft's written
request for an audit, Audible shall permit independent auditors designated by
Microsoft, paid by Microsoft, and approved by Audible, to examine, during
ordinary business hours, records, and materials of Audible for the purpose of
determining royalties due Microsoft or costs requiring reimbursement by
Microsoft and in such a manner as not to interfere with normal business
activities.  The auditor will sign a confidentiality agreement and will only
disclose to Microsoft any amounts overpaid or underpaid for the period examined.
Microsoft's request for an audit will be provided to Audible in writing and will
be made at least sixty (60) days prior to any audit.  Such request will not
occur more than once each year.  In the event an audit identifies an
underpayment of royalties by Audible, Audible shall pay an amount equal to the
sum of such underpayment, and shall reimburse Microsoft for all costs of the
audit (if the underpayment is more than 5% of amounts due for the period).

     8.5  Taxes.  All taxes, duties, fees and governmental charges of any kind
          -----                                                               
(except United States or state taxes based on the net income of Audible) which
are levied, assessed or otherwise imposed by or under the authority of any
government or political subdivision on any royalties payable hereunder, or any
aspect of this Agreement, shall be borne by Microsoft and

payments due to Audible hereunder.

           ----------                                                           
except in the event of a good faith payment dispute.

9.   NON-INTERFERENCE
     ----------------

     Audible shall not enter into any other agreement that would preclude
integration during the Term of any Audible audio technologies or Content with
Dedicated Reading Machines, Windows Media Player, and/or versions of Windows CE.
Nothing herein, except for [ *** ], shall be deemed a warranty that all Content
is available for use via Microsoft Products based on Windows 95 and 98 and
Windows NT.  Audible reserves the right to exclude Content for which Audible may
not possess the required licensed rights, and to acquire individual items of
Content, if it is beneficial to Audible's business in its reasonable opinion,
which may not permit distribution of such Content via all or some Microsoft
Products.

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.

           ------------------- ----------                                       
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.

WITH RESPECT TO THIRD PARTY CLAIMS FOR INFRINGEMENT OR MISAPPROPRIATION.

the termination or expiration of this Agreement or to protect its legal rights
hereunder. Termination or expiration shall not effect the confidential nature of

           ---------                                                      

     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.

Microsoft shall designate Audible as a nonexclusive Clearinghouse as soon as

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

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

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

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%)

six (6) months old at time of audit.

officers of Audible and RN shall meet at a mutually acceptable time and place,
and thereafter as often as they reasonably deem necessary, to attempt to resolve
the dispute. All reasonable requests for information made by one party to the
other will be honored. All negotiations pursuant to this Section 17.1 are
confidential and shall be treated as compromise and settlement negotiations for
purposes of the Federal Rules of Evidence and state rules of evidence.

     17.2 Arbitration.  If any dispute relating to this Agreement shall not have
          -----------                                                           
been resolved through the use of the non-binding procedures specified in Section
17.1 within one hundred (100) days of the initial notice of either party to the
other of a dispute, such dispute shall be settled by binding arbitration;
provided, however, that if one party has requested the other to participate in
the non-binding procedure specified in Section 17.1 and the other has failed to
participate, the requesting party may initiate arbitration before expiration of
the above stated period. Arbitration shall be governed by AAA Rules, with
arbitrators to be mutually agreed upon by the parties. Arbitration shall take
place in King County, Washington.  The arbitrators shall not be empowered to
award damages in excess of compensatory damages, and each party hereby
irrevocably waives any right to recover such damages with respect to any dispute
or disagreement resolved by arbitration.  Notwithstanding the foregoing, the
prevailing party in any arbitration or other proceeding based on a dispute
arising out of this Agreement or the RMA Agreement shall be entitled to recover
its reasonable attorneys' fees and costs.

     17.3 Provisional Remedies.  A party, without prejudice to the mandatory
          --------------------                                              
procedures of this Section 17, may file a complaint for statute of limitations
or venue reasons, or seek a preliminary injunction or other provisional judicial
relief, if in its sole judgment such action is necessary to avoid irreparable
damage or to preserve the status quo.  Notwithstanding such action, the parties
will continue to participate in good faith in the procedures specified in this
Section 17.

     18.4 Export Licenses.  The parties acknowledge that the laws and
          ---------------                                            
regulations of the United States may restrict the export and re-export of

           RealMedia Architecture Partner Program Internet Agreement
                                        

This Agreement is entered into as of November 12, 1998 (the "Effective Date") by
and between RealNetworks, Inc., a Washington corporation with a principal place
of business at 1111 Third Avenue,   Suite 2900, Seattle, Washington 98101 ("RN")
and Audible Inc., a Delaware corporation with an address at 65 Willowbrook
Blvd., Wayne, NJ 07470  ("Partner").

WHEREAS, RN has developed and owns all right, title and interest in the
RealMedia Architecture ("RMA", as further defined below), an open platform for
development of streaming media applications and tools, which allows software
developers to build new applications and extend current applications to inter-
operate with a wide variety of datatypes;

WHEREAS, RN has established a licensing program (the "Partner Program") which
allows independent software developers to create, market and sell applications
based on RMA, and to receive other benefits of participating in the Partner
Program; and

WHEREAS, Partner desires to participate in the Partner Program and to receive
the attendant rights and benefits;

NOW, THEREFORE, in consideration of the mutual promises and covenants set forth
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

1.   DEFINITIONS

1.1  "License Key" means the authorization code that is generated by the License
     Key Tool and that enables RMA Server Software to stream RealMedia
     datatypes. License Keys that generate User-Streams and enable features of a
     Partner Product are provided to a Partner's end-user customers.

1.2  "License Key Tool" means the version of the License Key Tool that is
     provided to Partner by RN, which is specific and unique to the Partner
     Product. The License Key Tool is used to generate unique License Keys for a
     Partner Product.

1.3  "Licensed Software" means RN Players, the RealMedia SDK, including
     associated RealMedia Libraries, RMA Server Software, whether in Object Code
     or Source Code form, License Key Tools and License Keys, and related User
     Documentation and specifications.

1.4  "New Release" means a new major release of the RMA Servers or the Partner
     Products in which major new functionality has been added in addition to any
     complement of bug fixes supplied, and which is designated as a change in
     the digit to the left of the decimal point in the product version number
     [(x).x.x]. "Update" means a minor release, enhancement, revision,
     modification or upgrade of the RMA Servers or Partner Products, designated
     as a change in the tenths digit in the product version number [x.(x).x], or
     in the digit to the right of the tenths digit in the product version number
     [x.x.(x)]. By way of clarification, if either party markets a new and
     distinct product along with and in addition to an existing program, then
     such new and distinct product shall be treated as a New Release, not an
     Update.

1.5  "Object Code" means computer code assembled or compiled in magnetic or
     electronic binary form on software media, which are readable and useable by
     machines, but not generally readable by humans without reverse-engineering,
     reverse-compiling or reverse-assembly.

1.6  "Partner Product(s)" means the products and applications developed by
     Partner which are compatible with RMA Servers, as further described on
     Exhibit A hereto. Partner Products shall include:

     (a)  "Partner Client Software," which means software that connects to an
          RMA Player and utilizes the RMA application programming interfaces
          ("APIs");

                                      -1-
<PAGE>
 
     (b)  "Partner Tools," which means software tools that may import datatypes
          and export datatypes using the RealMedia Libraries; and/or that are
          used to perform RMA-related functions including, but not limited to,
          server administration, plug-in file systems, server monitoring, and
          assembly; and

     (c)  "Partner Server Applications," which means software that interfaces
          with an RMA Server and adds datatypes that can be streamed from an RMA
          Server.

1.7  "RealMedia Architecture" or "RMA" means the software platform developed by
     RN that allows for the development of streaming media products and tools,
     and which is designed specifically for the existing infrastructure of the
     Internet and corporate Intranets.  RMA includes the following components:

     (a)  "Players," which are stand-alone applications or as components
          embedded in other applications that play media files.

     (b)  "RealMedia Datatypes," which are datatypes that can be streamed using
          RMA Server APIs and played using RMA Player APIs.

     (c)  "RealMedia Libraries," which are contained in the RealMedia SDK and
          are Object Code implementations of various APIs.

     (d)  "RealMedia SDK" or "SDK," which contains the tools and information
          needed for software developers to create tools for use in producing
          streaming media and to adapt or build applications that stream from
          RMA Servers and play in Players.  The SDK contains a Player, Player
          APIs, Server APIs, RealMedia Libraries, Sample Source Code and
          RealMedia Server Software for use solely in developing Partner
          Products.

     (e)  "RMA Server Software" or "RMA Server" in Object Code form, which
          streams files reliably over networks, and which has the capabilities
          set forth on Exhibit B hereto.

     (f)  "Sample Source Code," which provides an example of how to develop an
          RMA application.

1.8  "Term" is defined in Section 8.1.

1.9  "Territory" means the world, except as otherwise limited by Section 15.5.

1.10 "User Documentation" means RN's user manuals, technical manuals, release
     notes including advertisements for RMA Servers, installation and operation
     instructions, and other data and documentation describing the use of RMA
     Servers normally supplied to RN's customers.

1.11 "User-Stream" means the stream of media-compatible data necessary to
     deliver the media type associated with a Partner Product from an RMA Server
     to a single end-user client computer.  The number of User-Streams being
     delivered by a given RMA Server is measured by counting the number of end-
     users simultaneously served by User-Streams originating at that RMA Server.

2.   DEVELOPMENT LICENSE

2.1  License.  Subject to the terms and conditions of this Agreement, RN grants
     -------

8.4  Effect of Termination.
     --------------------- 

     (a)  Upon the effective date of termination of this Agreement for a
          material breach by Partner, the licenses granted hereunder shall
          terminate immediately. Partner will either immediately return all
          Licensed Software to RN or certify in writing to RN that all copies of
          all Licensed Software have been destroyed.  RN may discontinue
          promotion and distribution of Partner Products or continue to
          distribute Partner Products during the Sell-Off Period, set forth in
          Section 8. 3(b), at its sole discretion.    Notwithstanding anything
          in this Agreement to the contrary, under no circumstances may Partner
          distribute Partner Client Software after the expiration or termination
          of this Agreement, for any reason, without RN's express written
          consent.

     (b)  For two (2) months after the expiration or termination of this
          Agreement other than by reason of Partner's material breach ("Sell-Off
          Period"), Partner may advertise and sell the Partner Products, RMA
          Server and the License Keys in its inventory or necessary to fulfill
          orders confirmed as of the expiration or termination date, and shall
          pay License Fees and render statements in the same manner as during
          the Term.  After the end of the Sell-Off Period, Partner shall return
          to RN, at Partner's expense, all copies of the Partner Products, RMA
          Server and the License Keys, or RN may instruct Partner to destroy
          them.  Partner shall furnish RN with affidavits certified by an
          officer of Partner evidencing such destruction.

     (c)  Any termination of this Agreement shall not release Partner from
          paying any amount that may then be owing to RN, or that may become due
          to RN in the future.

     (d)  Notwithstanding any other terms or conditions of the Agreement, the
          rights of end-user customers to use any RMA Servers or License Keys
          distributed by Partner shall survive any termination or expiration of
          the Agreement, provided that License Fees for said RMA Servers and
          License Keys have been paid to RN.

9.   CONFIDENTIALITY

     "Confidential Information" means any trade secret information or
     information otherwise designated by a party as being confidential relating
     to either party's products, product plans, designs, computer code,
     technical information, costs, pricing, financing, marketing plans, business
     opportunities, personnel, research and development or know-how.
     Confidential Information shall not include information that (i) is or
     becomes generally known or available through no fault of the receiving
     party, (ii) was known by or disclosed to the receiving party prior to
     disclosure, (iii) is independently developed by the receiving party, or
     (iv) is made generally available by the disclosing party without any
     restriction. The parties shall use reasonable efforts and at least the same
     care that each uses to protect its own Confidential Information of like
     importance, to prevent unauthorized dissemination or disclosure of the
     other party's confidential information during and for three (3) years
     following the last day of the Term.  Neither party will use the other's
     Confidential Information for purposes other than those necessary to
     directly further the purposes of this Agreement.  Neither party will
     disclose to third parties the other's Confidential Information without the
     prior written consent of the other party, provided, however, that nothing
     will preclude a party from making disclosure to a third party for the
     purpose of due diligence in a financing transaction, merger, acquisition,
     business combination or other similar transaction, or from making any
     disclosures to any governmental agency having jurisdiction over the
     disclosing party, or unless otherwise required by law, government order or
     court proceeding.  Each party shall return the Confidential Information to
     the other party upon termination of the Agreement or upon the request of
     the other party.  Except as expressly provided in this Agreement, no
     ownership or license right is granted in any Confidential Information.

      Partner Products, including any copyright, patent, trade secret, or other
      intellectual property rights therein, subject to RN's underlying ownership

      Information. Notwithstanding the foregoing, Partner agrees that it shall
      not register or attempt to register any patents in connection with any
      Partner Product, including, but not limited to, in any device, process,
      method, function or invention included therein or necessary for the
      operation thereof, which would in any way interfere with, limit or
      prohibit RN's continued use, development or ownership of RMA.

10.2  RN.  RN shall retain all right, title and interest in and to the Licensed
      --                                                                       
      Software, including any copyright, patent, trade secret, or other
      intellectual property rights therein, all RN trademarks and all RN
      Confidential Information, and any copies thereof, regardless of the media

      acknowledges and agrees that the Licensed Software is proprietary to RN,
      and is protected by the copyright laws of the United States and
      international copyright treaties. Unauthorized copying of the Licensed
      Software, including modification, merger or inclusion with any other
      software, is expressly forbidden. Partner shall not be deemed, by anything
      contained in or done pursuant to this Agreement, to acquire any right,

      intellectual property of RN, and shall do nothing to prejudice the value

      ninety (90) days from the date of delivery to Partner: (i) the Licensed
      Software, if operated as directed, will substantially achieve the
      functionality described in the User Documentation, and (ii) that the media
      containing the Licensed Software, if provided by RN, is free in material
      respects from defects in material and workmanship; provided, however, that
      the foregoing warranty is expressly contingent (and shall be otherwise
      void) upon: (1) the use of the Licensed Software strictly in accordance
      with the instructions and User Documentation therefor; (2) the absence of
      misuse or damage thereto; (3) the absence of any alteration or
      modification thereto; and (4) Partner's acceptance of Licensed Software
      for distribution with knowledge that the media upon which the Licensed
      Software are reproduced may contain certain defects. RN makes no
      representation or warranty that the information or functions contained in
      the Licensed Software will meet Partner's requirements or that the use or
      operation of the Licensed Software will be uninterrupted, error free or
      secure, or that any Licensed Software defects are correctable or will be
      corrected. THE FOREGOING WARRANTY SHALL NOT APPLY TO THE SAMPLE SOURCE
      CODE, WHICH IS PROVIDED TO PARTNER AS IS, WITHOUT WARRANTY OF ANY KIND.

11.2  NO OTHER WARRANTIES. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, RN
      -------------------

      --------                                                               
      breach of the limited warranty set forth in Section 11.1 shall be, in RN's
      sole discretion: (i) to replace Partner's defective media; or (ii) to
      advise Partner how to achieve substantially the same functionality with
      the Licensed Software as described in the User Documentation through a
      procedure different from that set forth in the User Documentation.
      Repaired, corrected or replaced Licensed Software and User Documentation
      shall be covered by this limited warranty for period remaining under the
      warranty that covered the original Software, or if longer, for thirty (30)
      days after the date RN either shipped to Partner the repaired or replaced
      Licensed Software or RN advised Partner as to how to operate the Licensed
      Software so as to achieve the functionality described in the
      Documentation, whichever is applicable.

      Indemnifying Party's products after receiving prior written notice from
      the Indemnifying Party that the Indemnified Party should cease such
      activities due to a third party claim of infringement against such
      products; or (ii) the claim of infringement results from the Indemnified
      Party's combination or use of the Indemnifying Party's products with any
      third party product, program or data not supplied by the Indemnifying
      Party.

12.2  Conditions of Indemnification.  A party's obligation to indemnify the 
      -----------------------------

CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK

14.   DISPUTE RESOLUTION

Any dispute arising out of or relating to this Agreement shall be resolved in

           ----------------------                                               
resolve any dispute relating to this Agreement promptly by negotiation between
executives who have authority to settle the controversy.  In the event a dispute
cannot be resolved, either party may give the other party written notice of any
dispute not resolved in the normal course of business.   Within fifteen (15)
days after delivery of such a notice, the receiving party shall submit to the
other a written response.  The notice and response shall include a statement of
each party's position and a summary of arguments supporting that position.
Within thirty (30) days after delivery of the disputing party's notice, the

time and place, and thereafter as often as they reasonably deem necessary, to
attempt to resolve the dispute.  All reasonable requests for information made by
one party to the other will be honored.  All negotiations pursuant to this
Section 14.1 are confidential and shall be treated as compromise and settlement
negotiations for purposes of the Federal Rules of Evidence and state rules of
evidence.

      14.2 Arbitration.  If any dispute relating to this Agreement shall not 
           -----------                        
have been resolved through the use of the non-binding procedures specified in
Section 14.1 within one hundred (100) days of the initial notice of either party
to the other of a dispute, such dispute shall be settled by binding arbitration;
provided, however, that if one party has requested the other to participate in
the non-binding procedure specified in Section 14.1 and the other has failed to
participate, the requesting party may initiate arbitration before expiration of
the above stated period. Arbitration shall be governed by AAA Rules, with
arbitrators to be mutually agreed upon by the parties. Arbitration shall take
place in King County, Washington. The arbitrators shall not be empowered to
award damages in excess of compensatory damages, and each party hereby
irrevocably waives any right to recover such damages with respect to any dispute
or disagreement resolved by arbitration.

reformed only to the extent necessary to make it enforceable, and such decision
shall not affect the enforceability of such provision under other circumstances,

waiver of the right of such party thereafter to enforce such provisions.  Any
and all remedies herein expressly conferred upon a party shall be deemed
cumulative and not exclusive of any other remedy conferred hereby or by law, and
the exercise of any one remedy shall not preclude the exercise of any other.

     such information and material (or cause or permit others to do so) other
     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
     source code and object code form), the terms of agreements with third

           (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

     Firmware that Audible regards as proprietary and confidential.  In this
     regard, Diamond agrees that neither Diamond nor its employees and agents

     Software, or the Audible Firmware to any person, organization, company,

confidentiality, (c) information that, subsequent to disclosure, is rightfully
obtained by the receiving party from a third party under no obligation or
restriction of confidentiality, and (d) information that is independently
developed by the receiving party without resort to information of the other

and permanent injunctive relief and other equitable relief for any breach of
this Section 15.

residents of the State of New Jersey, and entered into and performed entirely in
the State of New Jersey, without giving effect to principles of conflict of
laws. Any action instituted by either party arising out of this Agreement for
interim relief shall only be brought, tried and resolved in the State of New
Jersey or the State of California, at the option of the party bringing the
claim.

     (b) Any controversy or claim arising out of or relating to this Agreement
for the breach hereof which cannot be settled by the parties pursuant to Section
16.3, shall be settled by arbitration in accordance with the commercial
arbitration rules of the American Arbitration Association as set forth herein.
Each party may select one (1) arbitrator.  Selection shall be completed within
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

                                 AUDIBLE, INC.


   1.  Issuance.  This Warrant is issued to Microsoft Corporation ("Microsoft")
       --------                                                                
by Audible, Inc., a Delaware corporation (hereinafter with its successors called
the "Company").

   2.  Purchase Price; Number of Shares.  Subject to the terms and conditions
       --------------------------------                                      
hereinafter set forth, the registered holder of this Warrant (the "Holder"),
commencing on the date hereof, is entitled upon surrender of this Warrant with
the subscription form annexed hereto duly executed, at the office of the Company
or such other office as the Company shall notify the Holder of in writing, to
purchase from the Company at the price per share (the "Purchase Price") set
forth on Schedule A hereto such number of fully paid and nonassessable shares of
         ----------                                                             
Common Stock, $0.01 par value, of the Company (the "Common Stock") as is set
forth on Schedule A hereto (the "Warrant Shares").  This Warrant is fully
         ----------                                                      
vested.

   3.  Payment of Purchase Price; Cashless Exercise.
       -------------------------------------------- 

   (a) The Purchase Price may be paid in cash, by check or wire transfer in
immediately available funds, or as provided in 3(b) below.

   (b) At any time during the term of this Warrant, the Holder may also elect to
exercise this Warrant (the "Conversion Right") with respect to a particular
number of Warrant Shares (the "Converted Warrant Shares"), and the Company shall
deliver to the Holder (without payment by the Holder of the Purchase Price in
cash or any other consideration (other than the surrender of rights to receive
Warrant Shares hereunder)) that number of shares of Common Stock equal to the
quotient obtained by dividing: (x) the difference between (i) the product of (A)
the Current Market Price of a share of Common Stock multiplied by (B) the number
of Converted Warrant Shares and (ii) the product of (A) the Exercise Price
multiplied by (B) the number of the
<PAGE>
 
Converted Warrant Shares, in each case as of the Conversion Date (as defined in
Section 3(c) below)), by (y) the Current Market Price of a share of Common Stock
on the Conversion Date. No fractional Warrant Shares shall be issuable upon
exercise of the Conversion Right, and if the number of Warrant Shares to be
issued determined in accordance with the following formula is other than a whole
number, the Company shall pay to the holder of this Warrant an amount in cash
equal to the Current Market Price of the resulting fractional Warrant Share on
the Conversion Date.

   (c) The Conversion Right may be exercised by the Holder by the surrender of
this Warrant as provided in Section 3(b), together with a written statement
specifying that the Holder thereby intends to exercise the Conversion Right and
indicating the number of Converted Warrant Shares which are covered by the
exercise of the Warrant.  Such conversion shall be effective upon receipt by the
Corporation of this Warrant, together with the aforesaid written statement, or
on such later date as is specified therein (the "Conversion Date").  The
Corporation shall issue to the Holder as of the Conversion Date a certificate
for the Warrant Shares issuable upon exercise of the Conversion Right and, if
applicable, a new warrant of like tenor evidencing the balance of the Warrant
Shares remaining subject to this Warrant.

   (d) The term "Current Market Price" for the Common Stock as of a specified
date shall mean:  (i) if the Common Stock is publicly traded on such date, the
average closing price per share over the preceding 10 trading days as reported
on the principal stock exchange or quotation system on which the Common Stock is
listed or quoted; or (ii) if the Common Stock is not publicly traded on such
date, the Board of directors of the Company shall determine Current Market Price
in its reasonable good faith judgment.  The foregoing notwithstanding, if Holder
advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a reputable
investment banking firm to undertake such valuation.  If the valuation of such
investment banking firm is greater than that determined by the Board of
Directors, then all fees and expenses of such investment banking firm shall be
paid by the Company.  In all other circumstances, such fees and expenses shall
be paid by Holder.


   4.  Partial Exercise.  This Warrant may be exercised in part, and the Holder
       ----------------

of this Warrant, covering the number of shares in respect of which this Warrant
shall not have been exercised.

   5.  Issuance Date.  The person or persons in whose name or names any
       -------------                                                   
certificate representing shares of Common Stock is issued hereunder shall be
deemed to have become the holder of record of the shares represented thereby as
at the close of business on the date this Warrant is exercised with respect to
such shares, whether or not the transfer books of the Company shall be closed.

   6.  Expiration Date.  This Warrant shall expire at the close of business on
       ---------------                                                        
November 18, 2003, and shall be void thereafter.
<PAGE>
 
   7.  Reserved Shares; Valid Issuance.  The Company covenants that it will at
       -------------------------------                                        
all times from and after the date hereof reserve and keep available such number
of its authorized shares of Common Stock, free from all preemptive or similar
rights therein, as will be sufficient to permit the exercise of this Warrant in
full.  The Company further covenants that such shares as may be issued pursuant
to the exercise of this Warrant will, upon issuance, be duly and validly issued,
fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issuance thereof.

   8.  Adjustment of Number of Shares; Exercise Price; Nature of Securities
       --------------------------------------------------------------------
         Issuable Upon Exercise of Warrants.
         ---------------------------------- 

   (a) Exercise Price; Adjustment of Number of Shares.  The Exercise Price set
       ----------------------------------------------                         
forth in Schedule A hereto and the number of shares purchasable hereunder shall
be subject to adjustment from time to time as hereinafter provided.

   (b) Reorganization, Reclassification, Consolidation, Merger or Sale.  If any
       ---------------------------------------------------------------         
capital reorganization or reclassification of the capital stock of the Company,
or any consolidation or merger of the Company with another entity, or the sale
of all or substantially all of the Company's assets to another person or entity
(collectively referred to as a "Transaction") shall be effected in such a way
that holders of Common Stock shall be entitled to receive stock, securities,
cash or assets with respect to or in exchange for Common Stock, then, as a
condition of such Transaction, reasonable, lawful and adequate provisions shall
be made whereby the holder of this Warrant shall thereafter have the right to
purchase and receive upon the basis and upon the terms and conditions specified
in this Warrant, upon exercise of this Warrant and in lieu of the Warrant Shares
immediately theretofore purchasable and receivable upon the exercise of the
rights represented hereby, such number, amount and like kind of shares of stock,
securities, cash or assets as may be issued or payable pursuant to the terms of
the Transaction with respect to or in exchange for the number of shares of
Common Stock immediately theretofore purchasable and receivable upon the
exercise of the rights represented hereby as if such shares were outstanding
immediately prior to the Transaction, and in any such case appropriate provision
shall be made with respect to the rights and interest of the holders to the end
that the provisions hereof (including, without limitation, provisions for
adjustments of the Exercise Price and of the number of Warrant Shares
purchasable and receivable upon the exercise of this Warrant) shall thereafter
be applicable, as nearly as may be practicable, in relation to any shares of
stock or securities thereafter deliverable upon the exercise hereof.

   (c) Stock Splits, Stock Dividends and Reverse Stock Splits.  If at any time
       ------------------------------------------------------                 
after the first to occur of: (i) the IPO or (ii) the date 12 months after the
date hereof, the Company shall subdivide its outstanding shares of Common Stock
into a greater number of shares, or shall declare and pay any stock dividend
with respect to its outstanding stock that has the effect of increasing the
number of outstanding shares of Common Stock, the Exercise Price in effect
immediately prior to such subdivision or stock dividend shall be proportionately
reduced and the number of Warrant Shares purchasable pursuant to this Warrant
immediately prior to such subdivision or stock dividend shall be proportionately
increased, and conversely, in case at any time after the first to occur of: (i)
the IPO or (ii) the date 12 months after the date hereof, the
<PAGE>
 
Company shall combine its outstanding shares of Common Stock into a smaller
number of shares, the Exercise Price in effect immediately prior to such
combination shall be proportionately increased and the number of Warrant Shares
purchasable upon the exercise of this Warrant immediately prior to such
combination shall be proportionately reduced.

     (d)  Dissolution, Liquidation or Wind-Up.  In case the Company shall, at 
          -----------------------------------               
any time prior to the exercise of this Warrant, dissolve, liquidate or wind up
its affairs, the holder hereof shall be entitled, upon the exercise of this
Warrant, to receive, in lieu of the Warrant Shares which the holder would have
been entitled to receive, the same kind and amount of assets as would have been
issued, distributed or paid to such holder upon any such dissolution,
liquidation or winding up with respect to such Warrant Shares, had such holder
hereof been the holder of record of the Warrant Shares receivable upon the
exercise of this Warrant on the record date for the determination of those
persons entitled to receive any such liquidating distribution.

     (e)  Accountant's Certificate.  In each case of an adjustment in the 
          ------------------------
