         other party's ownership interests and other rights as set forth above

9.       DISPUTES.

         9.1  ARBITRATION CLAUSE. All claims (including counterclaims and
         cross-claims) and disputes between Bolt and ATTWS must be resolved by
         submission to binding arbitration. The parties must submit any such
         disputes to the office of the American Arbitration Association ("AAA")
         in New York, New York (if initiated by ATTWS) or in Seattle,
         Washington (if initiated by Bolt)to be decided under the then current
         AAA commercial arbitration rules.

         9.2 LIMITATIONS OF ACTIONS. All claims and disputes covered by this
         Section 9 must be submitted to arbitration by initiating the
         arbitration not later than 180 days after the act or omission giving
         rise to the claim or dispute occurred. The failure to initiate
         arbitration within the period constitutes an absolute bar to the
         institution of any proceedings based on such act or omission. The
         aggrieved party must initiate arbitration under this Section 9 by
         sending written notice of an intention to arbitrate to all parties.
         The notice must contain a description of the dispute, the amount
         involved, and the remedy sought.

         9.3 RIGHT TO SEEK INJUNCTION. Notwithstanding anything in this
         Section 9, either party may bring court proceedings to seek an
         injunction or other equitable relief to enforce any right, duty or
         obligation under this Agreement. To obtain injunctive or other
         equitable relief, neither party shall be required to post a bond or,
         if required by law or by the court, the each party hereby consents to
         a bond in the lowest amount permitted by law.

         9.4 ENFORCEMENT OF AWARD. Neither party has the right to appeal the
         decision of the arbitrator. The award of the arbitrator may be
         confirmed or enforced in any court having jurisdiction.

         9.5 ATTORNEY'S FEES. If any arbitration or court action is commenced
         by either party, the substantially prevailing party in that action is
         entitled to recover its out-of-pocket and court costs and reasonable
         attorneys' fee incurred therein.

         9.6 CHOICE OF LAW. This Agreement shall be governed by, and construed
         in accordance with, the laws of the State of Delaware without
         reference to its choice of law rules. ATTWS and Bolt hereby
         irrevocably consents to personal jurisdiction and venue in the state
         and federal courts located in the borough of Manhattan in New York
         City, New York and in King County in the State of Washington with
         respect to any actions, claims or proceedings arising out of or in

         authorized representative of the waiving party.

                 development by Bolt of content and applications for the Bolt

              additional content and applications as these become available
              from Bolt. These Bolt applications will be branded the Bolt
              Mobile Channel or an equivalent, as mutually agreed by ATTWS and
              Bolt, within the Bolt mobile channel.

           2. Bolt will promote the ATTWS' PocketNet(R) and DMN Service in
              relevant locations on the Bolt site as mutually agreed by Bolt
              and ATTWS.

           3. Bolt will develop a promotional media campaign to support
              Section 5 of the Agreement and an online tutorial and demo that
              allows users to try before you buy. Additionally, this will
              include a significant amount of product pre-selling throughout
              the Bolt.com user experience to show users the specific ways they
              can benefit from these services. The online campaign will use
              commercially reasonable efforts to guarantee ATTWS exposure to
              all of the visitors to Bolt.com media network including Bolt's
              online distribution partners (Yahoo!, MSN/Hotmail, AOL, and
              ESPN).

           4. Bolt will maintain a channel on the Bolt Mobile Homedeck
              branded by ATTWS and to be used by PocketNet(R) subscribers for
              customer support and other services to be determined by ATTWS.
              This channel will appear no lower than line 8 on the first
              customer screen.

           5. Bolt will use commercially reasonable efforts to make the Bolt
              Mobile Channel feature complete, tested and production-ready for
              PocketNet(R) Service launch, forecast for [ * ]. The exact date
              will be determined by Bolt and ATTWS.

           6. The Bolt Mobile Channel will be comprised of HDML pages
              specifically designed for wireless delivery, and will not rely on
              automated reformatting of HTML web pages. In addition, SMS may be
              used as a delivery mechanism for alerts. In future versions of
              the Bolt Mobile Channel, WML may be used instead of HDML. In
              addition to the content and services provided by Bolt, Bolt will
              aggregate additional content providers to meet all the content
              needs of the teen market.

           7. Bolt will create a series of research projects and a constant
              services evaluation process to determine what customers use and
              like. Research will focus on reducing user churn and creating new
              products and services to meet users' evolving needs. Research
              studies will cover screen for all ATTWS services, customer screen
              and an optimization study.
