     Notwithstanding the above, the individual components of the Development
Work shall be deemed accepted upon commercial distribution of the component in
question, and upon completion of the [* * *] period stated above without any
report of errors.  Errors shall mean failure of the deliverable to comply in a
substantial or material way with the agreed upon specifications.

     3.2   Updates.  During the term of this Agreement, whenever Audible creates
           -------                                                             
an Update to the functionality of the Client Software that is related to the
Audible Software for Windows CE, Audible shall create a corresponding Update to
the Audible Software for Windows CE and deliver such Audible Software for
Windows CE Update to Microsoft no later than first commercial release of such
Client Software Update.  In order to facilitate the simultaneous release of any
particular Client Software Update and the corresponding Audible Software for
Windows CE Update, Audible will cooperate with Microsoft in the development of
such Updates (including, by way of example, providing development assistance and
information on such Updates).  Upon receipt of any Update, Microsoft shall

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

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.

     (c)  Source Code License.  The license to use source code and related
          -------------------                                            
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
licensees who have a right to request and receive the source code of Microsoft
Products, in which case such disclosure shall be pursuant to the same terms and
conditions applicable to disclosure of the source code of Microsoft's own
programs,

     (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
release of Windows CE for Palm-top devices or AutoPC as a standard module of
such release's functionality and direct successor versions commercially released
for a period of five (5) years, and for so long as Microsoft continues to
promote and enable access to Audible Content via such derivative works for
Audible Software for Windows CE in such versions of Windows CE, or (ii)
Microsoft pays Audible a mutually agreed, one-time license fee [* * *].

     (e)  Microsoft's obligation to "promote Audible Content" as used in Section

          (i)  Should software that allows browsing of the Internet be included
in the operating system for Windows CE for Palm-top devices or AutoPC, and
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.

     4.4  License to Microsoft Data and Software.  When Microsoft provides
          --------------------------------------

activities.  The auditor will sign a confidentiality agreement and will only
disclose to Microsoft any amounts overpaid or underpaid for the period examined.

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

other party to this Agreement, which permission will not be unreasonably
withheld.

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

     14.1. Term.  The term of this Agreement shall commence on the Effective
           ----                                                            
Date and continue for an initial period of five years unless terminated earlier
pursuant to Section 14.2. hereof (the "Term").  This Agreement will be

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

           b.  Microsoft may, at its option, terminate this Agreement upon

           --------------------                                         
intent to terminate this Agreement does not relieve either party of any

inclusive of those terms and conditions which extend beyond the date of
termination.

     14.4  Effect of Termination.  Upon termination of this Agreement for any

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

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

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

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

16.  [* * *]

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

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

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

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

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

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

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

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

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

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

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

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

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

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

contemplated by the parties pursuant to this Agreement shall be deemed to create
an agency, partnership, employment or joint venture relationship between the
parties.  Each party shall be deemed to be acting solely on its own behalf and,
except as expressly stated, has no authority to pledge the credit of, or incur
obligations or perform any acts or make any statements on behalf of, the other
party.  Neither arty shall represent to any person or permit any person to act

party's officers or employees, agents or contractors shall be deemed officers,

this Agreement, both parties may announce and/or confirm the existence of this
Agreement to the business, trade and general press, or to any other person or
entity provided that the parties agree on the content, and date of the
announcement, and venue and vehicle for the announcement.

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

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

     17.10 Attorneys' Fees.  A prevailing party in an action to enforce this

party.  Where appropriate the singular shall include the plural.  The headings

substantive meaning. In the event of a conflict between the provisions of the
