Date (or the date of delivery to AudioNet for future released versions, if any,
of RN Software made during the term hereof): (i) the final or "Gold" version of
the RN Software, if operated as directed, will substantially achieve the
functionality described in the Documentation; and (ii) that the media
containing the Gold version of the RN Software, if provided by RN, is free in
material respects from defects in material and workmanship; provided, however,

instructions and Documentation therefor; (B) the absence of misuse or damage
thereto; and (C) the absence of any alteration or modification thereto. RN
makes no warranty that AudioNet's use of the RN Software will be uninterrupted

case will RN be liable for any representation or warranty made to any third
party by AudioNet. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, RN AND
ITS SUPPLIERS DISCLAIM ALL OTHER WARRANTIES, EITHER EXPRESS OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTIBILITY AND
FITNESS FOR A PARTICULAR PURPOSE WITH RESPECT TO THE RN SOFTWARE.

with the RN Software during the applicable warranty period will RN be obligated
to honor this limited warranty.

<PAGE>   9
(iii)   RN's Breach. Immediately upon termination of this Agreement for RN's
material breach of this Agreement [*], AudioNet shall have a fully paid-up
license to the RN Software consistent with the terms of Sections 1(a) hereof but

Any termination of this Agreement shall not act as a release of either party
hereto from any liability for breach of such party's obligations under this
Agreement.

         10.     CONFIDENTIAL INFORMATION.

         (a)     Confidential Information. "Confidential Information" shall
mean information about the disclosing party's business or activities that are
proprietary or confidential, which shall include all business, financial,
technical and other information of a party marked or designated by such party
as "confidential" or "proprietary"; or information which, by the nature of the
circumstances surrounding the disclosure, ought in good faith to be treated as
confidential, including without limitation information relating to the RN
Software; and the fact that the parties are in negotiation and the proposed
offer, terms and conditions of this Agreement; provided that information shall
not be considered Confidential Information of a party if it can be shown that
such information: (i) is known to the recipient on the Effective Date directly
or indirectly from a source other than one having an obligation of
confidentiality to the providing party; (ii) hereafter becomes known
(independently of disclosure by the providing party) to the recipient from a
source other than one having an obligation of confidentiality to the providing
party; or (iii) becomes publicly known or otherwise ceases to be confidential,
except through a breach of this Agreement by the recipient.

         (b)     Protection of Confidential Information. RN and AudioNet
recognize that, in connection with the performance of this Agreement, each of
them may disclose to the other its Confidential Information, including the
creation of materials and the development of technology and techniques that are
not generally known in the industry. The party receiving any Confidential
Information of the other party agrees to maintain the confidential status of
such Confidential Information and not to use any such Confidential Information
for any purpose other than the purposes for which it was originally disclosed
to the receiving party, and not to disclose any of such Confidential
Information to any third party. In addition, each party agrees not to
disassemble, decompile, or otherwise reverse engineer the products or
technology of the other party or otherwise attempt to learn the source code,
structure or algorithms or ideas underlying such products or technology or any
Confidential Information. The parties' obligations set forth in this section
shall survive any expiration or termination of this Agreement.

         (c)     Permitted Disclosure. RN and AudioNet acknowledge and agree
that each may disclose any given Confidential Information: (i) as required by
law; (ii) to their respective directors, officers, employees, attorneys,
accountants and other advisors or independent contractors, who are under an
obligation of confidentiality, on a "need-to-know" basis; (iii) to investors or
joint venture partners, who are under an obligation of confidentiality, on a
"need-to-know" basis; or (iv) in connection with any arbitration


*Confidential Treatment Requested
                                       9
<PAGE>   10
or litigation between the parties involving such Confidential Information and
each party shall endeavor to limit disclosure to that purpose.

         (d)     Applicability. The foregoing obligations of confidentiality
shall apply to directors, officers, employees and representatives of the
parties and any other person to whom the parties have delivered copies of, or
permitted access to, such Confidential Information in connection with the
performance of this Agreement, and each party shall advise each of the above of
the obligations set forth in this Section 10.

         11.     RESOLUTION OF DISPUTES.

         (a)     Dispute Resolution. Any dispute arising out of or relating to
this Agreement shall be resolved in accordance with the procedures specified in
this Section 11, which shall be the sole and exclusive procedures for the
resolution of any such dispute.

         (b)     Executive Negotiations. The parties shall attempt in good
faith to 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 senior executive officers of AudioNet 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 11 are confidential and shall be treated as compromise
and settlement negotiations for purposes of the Federal Rules of Evidence and
any state rules of evidence.

         (c)     Arbitration. If any dispute relating to this Agreement shall
not have been resolved through the use of the non-binding procedures specified
in Section 11 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 11 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 Los Angeles County, California and the arbitrators shall
apply, to the greatest extent possible, the laws of the State of California
without giving regard to its conflict of laws principles. 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.

         (d)     Provisional Remedies. A party, without prejudice to the
mandatory procedures of this Section 11, 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 11.

         12.     GENERAL.

         (a)     Independent Contractor. The relationship created by this
Agreement is one of independent contractors, and not partners, franchisees or
joint venturers. No employees, consultants, contractors or agents of one party
are employees, consultants, contractors or agents of the other party, nor do
they have any authority to bind the other party by contract or otherwise to any
obligation, except as expressly set forth herein. Neither party will represent
to the contrary, either expressly, implicitly or otherwise.

                                       10
<PAGE>   11
         (b)     Export Licenses. The parties acknowledge that the laws and
regulations of the United States may restrict the export and re-export of
certain commodities and technical data of United States origin. Each party
agrees that it will not export or re-export the RN Software in any form without
the appropriate United States or foreign government licenses. In particular but
without limitation, none of the RN Software, Documentation or underlying
information or technology may be exported or re-exported (i) into (or to a
national or resident of) Cuba, Iraq, Libya, Yugoslavia (Serbia and Montenegro),
North Korea, Iran, Angola, Sudan, Syria or any other country to which the U.S.
has embargoed goods; or (ii) to anyone on the U.S. Treasury Department's list
of Specially Designed Nationals or the U.S. Commerce Department's Table of
Deny Orders.

         (c)     Miscellaneous. This Agreement, and the Exhibits attached
hereto and made a part hereof, [*] constitute the
complete and exclusive agreement between RN and AudioNet and supersedes all
prior oral or written understandings or agreements not specifically
incorporated herein. This Agreement may not be modified except in a writing
duly signed by an authorized officer of RN and AudioNet. If any provision of
this Agreement is held to be unenforceable for any reason, such provision shall
be reformed only to the extent necessary to make it enforceable, and such
decision shall not affect the enforceability of such provision under other
circumstances, or of the remaining provisions hereof under all circumstances.
Headings shall not be considered in interpreting this Agreement.

         (d)     Governing Law. This Agreement shall be governed by the laws of
the State of California, United States of America, excluding that body of law
known as conflicts of law. This Agreement shall not be governed by the United
Nations Convention of Contracts for the International Sale of Goods, the
application of which is hereby expressly excluded.

         (e)     Survival of Agreements and Representations and Warranties. All
agreements, representations and warranties contained herein or made in writing
in connection herewith, to the extent applicable, shall survive the execution
and delivery of this Agreement and the consummation of the transactions
contemplated hereby. In addition, the following provisions shall survive the
termination of this Agreement for any reason.: 1(e), (f) and (g), 2(a) and
(d), 3(d), 6, 9(c), 10, 11 and 12(d), (e) and (l).

         (f)     Binding Effect. All covenants, representations, warranties and
other stipulations in this Agreement, given by or on behalf of any of the
parties hereto, shall bind and inure to the benefit of the respective
successors and permitted assigns of the parties hereto.

         (g)     Cumulative Powers. No remedy herein conferred upon a party to
this Agreement is intended to be exclusive of any other remedy, and each such
remedy shall be cumulative and in addition to every other remedy given
hereunder or now or hereafter existing at law, or in equity or by statute or
otherwise.

         (h)     Notices. All notices, requests, demands and other
communications hereunder shall be in writing and shall be deemed to have been
given (i) when hand delivered, including delivery by messenger or courier
service (or if delivery is refused, at the time of refusal), to the address set

         is available, and which (i) in the case of an Error in the RealAudio
         Server, affects more than 25% of the Real Players, or (ii) in the case
         of an Error in the Real Player, affects more than 25% of the Real
         Players. All other Errors which preclude core functions in the Real
         Server from being performed shall be Level 2 Errors.

                 (c)      "First Level Support" shall consist of accepting and
         handling end user calls and troubleshooting to the point of verifying
         that there is an Error and that the Error, if any, is in the Real

                 (d)      "Level 3 Error" shall mean any condition that results
         in a significant loss or degradation of functionality of the Real
         Server due to suspected or actual Errors in the Real Server.

                 (e)      "Level 4 Error" shall mean any condition (i) that
         precludes one or more nonessential functions of the Real Server from
         being performed due to suspected or actual Errors in the Real Server;
         or (ii) in which AudioNet's technical support personnel need
         reasonable assistance or information regarding the Real Server.

                 (f)      "AudioNet Contact" shall mean an individual
         designated in writing by AudioNet who is authorized to contact the
         Support Center. AudioNet may substitute AudioNet Contacts at any time

                 (g)      "Level 2 Error" shall mean any condition that
         precludes one or more major functions of the Real Server (e.g.
         intermittent system hang or temporary loss of data) from being
         performed due to suspected or actual Errors in the Real Server, and
         which (i) in the case of an Error in the RealAudio Server, affects
         more than 25% of the Real Players, or (ii) in the case of an Error in
         the Real Player, affects more than 25% of the Real Players. All other
         Errors which preclude one or more major functions in the Real Server
