          acquire)) a Reseller in the other party's territory.


3.        Each of ABBA and ABBA-W, on the one hand, and Dylan, on the other,

          that, Dylan may provide such contribution outside of ABBA-W's home
          territory if the recipient thereof is bound by non-exportation

          engage) in the other party's home territory in the business of
          developing or maintaining a Mobile Portal (as defined below).

          After the expiration of the 48-month period, Dylan and ABBA-W will
          discuss in good faith appropriate revisions to the restrictions on
          competition or the termination of such restrictions with respect to

          telecommunications markets.

D.    Non-Disclosure Commitment/Dylan Parent and Other.
      ------------------------------------------------

      1. ABBA-W and Dylan each hereby agree (and each intends to cause the
      agreement in this Section D to be set forth in a more complete definitive
      agreement) to keep confidential and protect each other's Proprietary
      Information. This will include ensuring that directors, secondees and any
      other employees with access to Proprietary Information of the other party
      remain bound by strict nondisclosure policies and procedures consistent
      with this Section D, and only utilize Proprietary Information for purposes
      related to the purposes for which such information was disclosed. In
      addition, each party further agrees that in no case shall any Proprietary
      Information of the other party be transferred in any form (including
      orally and visually) outside of the respective home territories.
      "Proprietary Information" shall mean any and all information of either
      party of a confidential nature, including without limitation non-public
      information relating to the disclosing party's technology, technical data,
      trade secrets, know how, customers, business plans, marketing activities,
      financial data and other business affairs that is disclosed by one party
      to the other party or that is otherwise learned by a party in the course
      of its discussions or business dealings with, or its physical or
      electronic access to the premises of, the other party that, if disclosed
      in written form, is conspicuously marked at the time of initial
      disclosure, or promptly thereafter, as the disclosing party's Proprietary
      Information, and, if in oral or visual form, is promptly followed by a
      writing delivered to the receiving party designating the information
      considered confidential; PROVIDED, HOWEVER, that "Proprietary Information"
      does not include any information that: (i) was in possession of or known
      to the receiving party, without any obligation of confidentiality to the
      disclosing party, prior to receiving it from the disclosing party; (ii)
      is, or subsequently becomes, publicly available without breach of these
      confidentiality provisions; (iii) is or becomes known or available to the
      receiving party from a source other than the disclosing party that, to the
      receiving party's knowledge, is not prohibited from disclosing such
      Proprietary Information to the receiving party by a contractual, legal or
      fiduciary obligation owed by such other third party to the disclosing
      party; (iv) is developed by or for the receiving party without use of the
      Proprietary Information; or (v) is or becomes available to the receiving
      party by lawful inspection or analysis of products or services offered for
      sale; or (vi) is disclosed to the receiving party by the disclosing party
      after receiving written notification from the receiving party that does
      not desire to receive any further Proprietary Information.

      2. The foregoing notwithstanding, the terms of confidentiality hereunder
      shall not be construed to in any way limit either party's right to
      independently develop or acquire products, services or other information
      without use of the other party's Proprietary Information. Each party
      acknowledges that the other party has developed and intends to continue to
      develop, both internally and with the assistance of third parties,
      products,


                                      -4-


<PAGE>


      services and other information related to Mobile Portals and
      data networks, including products, services and other information which
      may be similar to Proprietary Information disclosed by the other party.
      Accordingly, nothing herein, or any other agreement between the parties,
      will be construed as a representation or agreement that the receiving
      party will not develop or have developed for it (or deploy) products,
      services, concepts, systems or techniques that are similar to or compete
      with the products, concepts, systems or techniques contemplated by or
      embodied in the Proprietary Information of the other party, provided that
      the receiving party does not violate any of its obligations under this
      Section D in connection with such development. Further, notwithstanding
      any other provision hereof or agreement between the parties, both parties
      shall be free to use for any lawful purpose the residuals resulting from
      access to or work with any Proprietary Information, provided that such
      party shall maintain the confidentiality of the Proprietary Information as
      provided herein. The term "residuals" means information in non-tangible
      form, which may be retained by persons who have had access to the
      Proprietary Information, including ideas, concepts, know-how or techniques
      contained therein so long as such "residuals" are not themselves
      substantially identical to the Proprietary Information on which any such
      residual is based. Neither party shall have any obligation to limit or
      restrict the assignment of such persons or to make payment of any kind to
      the other party for any work resulting from the use of residuals.

      3. In the event that the receiving party is requested or becomes legally
      compelled to disclose any Proprietary Information, then before
      substantively responding to any such request or requirement, the receiving
      party will provide the disclosing party with prompt written notice of any
      such request or requirement so that the disclosing party may seek a
      protective order or other appropriate remedy, or both, or waive compliance
      with the provisions of this Section D or other appropriate remedy, or if
      the disclosing party so directs, the receiving party will exercise its own
      reasonable best efforts to assist the disclosing party in obtaining a
      protective order or other appropriate remedy at the disclosing party's
      expense. If, failing the entry of a protective order or other appropriate
      remedy or the receipt of a waiver hereunder, disclosure of any Proprietary
      Information is, in the opinion of the receiving party's counsel, required,
      the receiving party may furnish only that portion of the Proprietary
      Information which is in the opinion of the receiving party's counsel
      legally required to be furnished. In any event, the receiving party will
      cooperate fully with any action by the disclosing party to obtain an
      appropriate protective order or other reliable assurance that confidential
      treatment will be accorded the Proprietary Information.

      4. The obligations and covenants contained in this Section D shall be
      subject to and performed in accordance with any applicable U.S. and
      Japanese laws and regulations.
