Distributor's selling price to its customers shall be Distributor's sole
remuneration for sale of the Products. The initial prices for Manufacturer's
Products shall be delivered by Manufacturer to Distributor within a reasonable
time after the date of this Agreement. Said price shall be subject to change by

8. Report

Hakuto agrees to furnish to Manufacturer quarterly reports regarding sales to
customers or to prospective customers in the Territory.


9. Intellectual Property Rights

9.01 Property Rights. Distributor agrees that Manufacturer owns all right,
title, and interest in the product lines that include the Products and in all of
Manufacturer's patents, trademarks, trade names, inventions, copyrights,
know-how, and trade secrets relating to the design, manufacture, operation or
service of the Products. The use by Distributor of any of these property rights
is authorized only for the purposes herein set forth, and upon termination of
this Agreement for any reason such authorization shall cease.

9.02 Sale Conveys no Right to Manufacture or Copy. The Products are offered for
sale and are sold by Manufacturer subject in every case to the condition that
such sale does not convey any license, expressly or by implication, to
manufacture, duplicate or otherwise copy or reproduce any of the Products.
Distributor shall take appropriate steps with its customers, as Manufacturer may
request, to inform them of and assure compliance with the restrictions.

9.03 Confidentiality. Distributor acknowledges that by reason of its
relationship to Manufacturer hereunder it will have access to certain
information and materials concerning Manufacturer's business, plans, customers,
technology, and products that are confidential and of substantial value to
Manufacturer, which value would be impaired if such information were disclosed
to third parties. Distributor agrees that it will not use in any way for its own
account or the account of any third party, nor disclose to any third party, any
such confidential information revealed to it by Manufacturer. Distributor shall
take every reasonable precaution to protect the confidentiality of such
information. Upon request by Distributor, Manufacturer shall advise whether or
not it considers any particular information or materials to be confidential.
Distributor shall not publish any technical description of the Products beyond
the description published by Manufacturer (except to translate that description
into appropriate languages for the Territory). In the event of termination of
this Agreement, there shall be no use or disclosure by Distributor of any
confidential information of Manufacturer, and Distributor shall not manufacture
or have manufactured any devices, components or assemblies utilizing any of
Manufacturer's confidential information. Distributor expressly consents to
Manufacturer's use of Distributor's name in promotional materials and other
documents delivered to government agencies and otherwise.

9.04 Trademarks and Trade Names.

                (a) Use. During the term of this Agreement, Distributor shall
have the right to indicate to the public that it is an authorized distributor of
Manufacturer's Products and to advertise within the Territory such Products
under the trademarks, marks, and trade names that Manufacturer may adopt from
time to time ("Manufacturer's Trademarks"). Distributor shall not alter or
remove any Manufacturer's Trademark applied to the Products at the factory.
Except as set forth in this Section 9.04, nothing contained in this Agreement
shall grant to Distributor any right, title or interest in Manufacturer's
Trademarks. At no time during or after the term of this Agreement shall
Distributor challenge or assist others to challenge Manufacturer's Trademarks or
the registration thereof or attempt to register any trademarks, marks or trade
names confusingly similar to those of Manufacturer.

                (b) Approval of Representations. All representations of
Manufacturer's Trademarks that Distributor intends to use shall first be
submitted to Manufacturer for approval (which shall not be unreasonably
withheld) of design, color, and other details or shall be exact copies of those
used by Manufacturer. If any of Manufacturer's Trademarks are to be used in
conjunction with another trademark on or in relation to the Products, then
Manufacturer's mark shall be presented equally legibly, equally prominently, and
of greater size than the other but nevertheless separated from the other so that
each appears to be a mark in its own right, distinct from the other mark.

9.05 Patent, Copyright and Trademark Indemnity.

                (a) Indemnification. Distributor agrees that Manufacturer has
the right to defend, or at its option to settle, and Manufacturer agrees, at its
own expense, to defend or at its option to settle, any claim, suit or proceeding
brought against Distributor or its customer on the issue of infringement of any
United States or Japan patent, copyright or trademark by the Products sold
hereunder or the use thereof, subject to the limitations hereinafter set forth.
Manufacturer shall have sole control of any such action or settlement
negotiations, and Manufacturer agrees to pay, subject to the limitations
hereinafter set forth, any final judgment entered against Distributor or its
customer on such issue in any such suit or proceeding defended by Manufacturer.
Distributor agrees that Manufacturer at its sole


<PAGE>   5

option shall be relieved of the foregoing obligations unless Distributor or its
customer notifies Manufacturer promptly in writing of such claim, suit or
proceeding and gives Manufacturer authority to proceed as contemplated herein,
and, at Manufacturer's expense, gives Manufacturer proper and full information
and assistance to settle and/or defend any such claim, suit or proceeding. If
the Products, or any part thereof, are, or in the opinion of Manufacturer may
become, the subject of any claim, suit or proceeding for infringement of any
United States or Japan patent, copyright or trademark, or if it is
adjudicatively determined that the Products, or any part thereof, infringe any
United States or Japan patent, copyright or trademark, or if the sale or use of
the Products, or any part thereof, is, as a result, enjoined, then Manufacturer
may, at its option and expense either: (i) procure for Distributor and its
customers the right under such patent, copyright or trademark to sell or use, as
appropriate, the Products or such part thereof; or (ii) replace the Products, or
part thereof, with other suitable Products or parts; or (iii) suitably modify
the Products, or part thereof; or (iv) if the use of the Products, or part
thereof, is prevented by injunction, remove the Products, or part thereof, and
refund the aggregate payments paid therefor by Distributor, less a reasonable
sum for use and damage. Manufacturer shall not be liable for any costs or
expenses incurred without its prior written authorization.

                (b) Limitation. Notwithstanding the provisions of Subsection
9.05(a) above, Manufacturer assumes no liability for (i) infringements covering
completed equipment or any assembly, circuit, combination, method or process in
which any of the Products may be used but not covering the Products when used
alone; (ii) trademark infringements involving any marking or branding not
applied by Manufacturer or involving any marking or branding applied at the
request of Distributor; or (iii) infringements involving the modification or
servicing of the Products, or any part thereof, unless such modification or
servicing was done by Manufacturer.

                (c) Entire Liability. The foregoing provisions of this Section
9.05 state the entire liability and obligations of Manufacturer and the
exclusive remedy of Distributor and its customers, with respect to any alleged
infringement of patents, copyrights, trademarks or other intellectual property
rights by the Products or any part thereof.


10. Relationship of Parties

The relationship between Manufacturer and Hakuto shall not be that of a
principal and an agent, but shall be that of a seller and purchaser, each acting
as an independent contractor. Hakuto shall have no right or authority to incur,
assume or create, in writing or otherwise, any warranty, liability, or
obligation of any kind, express or implied, in the name of or on behalf of
Manufacturer.


11. Assignment

any of its rights or obligations hereunder in whole or in part to any
