a corporation duly organized under the laws of JAPAN, with its principal place

("Distributor"). IN CONSIDERATION OF THE MUTUAL COVENANTS AND PROMISES HEREIN
CONTAINED, THE PARTIES HERETO AGREE AS FOLLOWS:

1.   APPOINTMENT AND ACCEPTANCE

EST hereby appoints Distributor and Distributor hereby accepts appointment as an
exclusive distributor for the sale of EST hardware products and for the sale of
licenses and support services for the EST software products, in executable form,
specified in the attached Schedule B ("Products") to end-users located within

Schedule A ("Territory"). Additional EST products (including new versions of the
Products) may be included under this Agreement by the mutual written consent of
the parties in the form of an amendment to this Agreement. EST reserves the
right to delete any Product from this list of which development, production,
licensing or maintenance is discontinued by EST.

2.   DISTRIBUTION RIGHTS

A.   No Software Product shall be distributed to an end-user by Distributor, if
     the Product is designated a shrink-wrapped product by EST, until (i) the
     end-user executes an EST Software License Agreement, which identifies EST
     as the licensor and the end-user as the licensee, or (ii) the Product is
     packaged with an EST Software License Agreement, the terms and conditions
     of which the end-user agrees to comply with by opening the shrink-wrap
     package containing this same Agreement.

B.   The EST Software License Agreement is attached to, and made part of this
     Agreement as Schedule D. Any modification, deletion or change Distributor
     desires to make in any particular licensing transaction shall require the
     prior written approval of EST. EST reserves the right to change any of the
     terms and conditions of the attached EST Software License Agreement, or its
     licensing procedures, provided Distributor is given thirty (30) calendar
     days prior written notice of any such changes.

     applicable end-user.

     of the Products, all rights related thereto being reserved by EST.

F.   Except for copying as may be specifically provided by Schedule E,
     Distributor will not copy, in whole or in part, or modify, alter, reverse

     unreasonably withheld.

G.   In the event that copying is authorized by Schedule E for the purpose of
     making deliveries to Distributor's customers, Distributor shall reproduce

     form, including partial copies. Distributor agrees to keep a record of
     every copy made and to furnish such record to EST upon its request.

H.   Distributor is hereby granted an exclusive, non-transferable right to use
     as selling aids in the Territory, during the life of this Agreement, the
     trademarks identifying the Products. Distributor shall not sublicense or
     otherwise permit the use of said trademarks by other parties. All rights in

     thereafter, be and remain the sole property of EST and good will and other
     benefits associated therewith are hereby assigned and shall inure to the
     benefit of EST. Distributor shall not use said trademarks in any manner
     which would injure or destroy their value or diminish EST's property rights
     therein. Distributor shall promptly notify EST of any infringement or
     suspected infringement of said trademarks that may come to Distributor's
     attention and assist EST, at EST's expense, in taking action against such
     infringement as EST, in its sole discretion, may decide.

I.   Distributor is hereby granted the right to translate into Kanji and publish
     any of the technical or sales promotional materials for use in promoting
     EST products in Japan. Distributor will retain sole rights to such

extent it is based on a claim that an unmodified Product used by an end-user

the same. In the event that the Product becomes or, in EST opinion, is likely to
become the subject of a claim of infringement, EST may, at its option, secure

     documents, shall be in English.
