        necessary or desirable under the Laws of the applicable Government
        Entities.

 III.   FEE AND ROYALTY

 3.1    Fee Payment and Amount.  Licensee shall pay to LTC a license fee in
        accordance with the following schedule:

         *

        Payment to be made on or before September 5, 1997 to Lanxide K.K. as
        the agent of Lanxide (the "Fee").

         *

 3.2    Third Party Royalties.  In any case where use of Licensed Technology
        requires or required LTC to pay a royalty to a third party (whether
        lump-sum or payable by reference to sales) under the terms of any
        future third party license that LTC may enter into, then in the event
        that Licensee determines to use such Technology, Licensee will be
        responsible for payment to LTC of a further amount equal to the royalty
        payable to the third party attributable to sales by Licensee and its
        authorized sublicensees.  In case LTC needs to obtain a third party
        technology which LTC is aware may be useful to licensee and therefore
        may require Licensee to be responsible for additional royalty, Lanxide
        shall let Licensee know the need, with prior written form, and consult
        with Licensee as to whether such additional technology is truly
        necessary.  If Licensee decides such technology is unnecessary,
        Licensee shall have the right not to use such third party technology
        and therefore not be required to pay any third party royalty associated
        therewith.  Even though Licensee decides such technology is
        unnecessary, subject to the terms of this License Agreement, Licensee
        can use licensed technology not requiring such third party royalty.

 3.3    Tax Withholding.  Licensee may withhold taxes from royalties payable
        hereunder only to the extent that such withholding is required under
        applicable law and to the extent that Licensee provides copies of all
        documents required by LTC hereunder to claim credit for such foreign
        tax payment.

 3.4    Payment and Accounting.  Third party royalties due under this Agreement
        shall be paid in U.S. dollars to the bank account specified by LTC
        within 45 days after each of December 31, March 31, June 30 and
        September 30, in relation to the period of three (3) calendar months
        (or less in the case of the first such period) ending on such date.
        Overdue payments shall bear interest at the annual rate of two percent
        (2%) above the prime rate of Citibank, in New York.

 3.5    Books and Records.  Licensee shall keep proper books and records
        showing the description and price of products sold, and such records
        shall be open at all reasonable times to inspection by Lanxide or its
        representatives, who shall be entitled to take copies of such books and
        records.

 3.6    Currency Conversion.  For the purpose of converting into U.S. dollars
        the currency in which royalties may arise, the rate of exchange to be
        applied shall be the rate of exchange for the purchase of U.S. dollars
        with the currency quoted by Citibank, in New York as at the close of
        business on the last business day of the quarterly period to which a
        payment shall relate.

        sublicensees without the participation of any of the employees of LTC
        or its Affiliates and Licensee shall obtain the right to grant, and
        grant, to LTC a full world-wide, royalty-free, perpetual, irrevocable,

        relating to the Licensed Technology made by Licensee's employees with
        or without the participation of employees of authorized sublicensees or

                drawings, lists, and the like;

         (ii)   Data and other information employed in connection with the
                marketing of the products of Lanxide, LTC, Licensee, or their
                Affiliates including cost information, business policies and
                procedures, revenues and markets, distributors and customers,
                and similar items of information whether or not contained in
                documents or other tangible materials; and

        (iii)   Any other information obtained by the parties to this Agreement
                during the term hereof, that is not generally known to, and not
                readily ascertainable by proper means by, third parties.

 7.3    Precautions.  The parties hereto shall take all appropriate steps to
        prevent unauthorized disclosure of any Proprietary Information by their
        employees, which steps include the execution by all such persons of
        written agreements containing obligations of confidentiality,
        restricted disclosure and limited use relative thereto consistent with
        this Section 8 prior to disclosure of Proprietary Information to them.
        The parties shall not permit access to Proprietary Information by their
        employees, except on a need-to-know basis.  The parties shall further
        take all appropriate steps to protect the Proprietary Information
        against espionage, misuse, loss or theft.
 7.4    Exclusions.  The provisions of this Section 7 shall not apply to any
        Proprietary Information after (i) it has become generally available to
        the public through no fault of the receiving party or its employees,
        (ii) the receiving party can prove by clear and convincing documentary
        evidence that it was in its possession before disclosure hereunder and
        did not come directly or indirectly from the disclosing party or
        (iii) it becomes known to the receiving party through lawful disclosure
        from a third party that is not subject to a confidentiality agreement
        with any disclosing party or Affiliate.

 7.5    Permitted Disclosure.  Proprietary Information may not be disclosed by
        the receiving party without the prior written consent of the disclosing
        party, except that:

          (i)   Lanxide or LTC, as appropriate, may disclose such Proprietary
                Information to their employees on a need-to-know basis for the
                purposes of this Agreement in accordance with paragraph 8.3.

         (ii)   Lanxide may disclose Licensee's Proprietary Information to its
                Affiliates or its other licensees or sublicensees of the
                Licensed Technology, provided that prior to disclosure of the
                Proprietary Information, such Persons execute written
                agreements containing obligations of confidentiality consistent
                with this Section 7.

        (iii)   In the event that a third party wishes to evaluate Licensee's
                proprietary technology in connection with a business
                transaction with Lanxide or its Affiliates, Lanxide may
                disclose as much of Licensee's Proprietary Information to that
                third party as is necessary to conduct such evaluation,
                provided that prior to disclosure such third party executes a
                written agreement prohibiting use of the Proprietary
                Information for any reason other than evaluation of this
                technology and containing obligations of confidentiality
                consistent with this section 7.

 7.6    Government Regulations.  The provisions of this Section 7 shall not be
        deemed to obligate either party to do or refrain from doing any act,
        the doing or not doing of which would cause or reasonably be expected
        to cause either party to fail to fulfill or comply with any obligation
        or requirement imposed by any Governmental Regulation, provided that,
        any disclosures of Proprietary Information made to fulfill or comply
        with any such Regulation shall be made (i) only after notice to the
        other party, and (ii) under conditions invoking all confidentiality
        protections as are available by law or regulation.

        such performance at any time thereafter, nor shall the waiver by either
        party of a breach of any provision of this Agreement by the other party
