                          PATENT LICENSE AGREEMENT


This Agreement made and entered into this 12th day of October, 1994 by
and between Hitachi, Ltd., having a place of business at 6, Kanda-Surugadai,

WHEREAS, HITACHI owns and controls United States Patent Nos. 4,610,718
and 4,732,369, and has the right to grant a license under said patents;

WHEREAS, LICENSEE desires to acquire a nonexclusive license to make,
use and sell LICENSED PRODUCT (hereinafter defined) under LICENSED
PATENTS (hereinafter defined);

NOW, THEREFORE, in consideration of the premises and covenants
herein set forth, the parties agree as follows:

1. DEFINITIONS

1.1 The term "LICENSED PRODUCT" shall mean any ultra-fine particles
of less than 1 micron in size produced or processed using methods,
processes or apparatus of the type claimed in LICENSED PATENTS.

1.2 The term "LICENSED PATENTS" shall mean United States Patent Nos.
4,610,718 and 4,732,369, and any divisional, continuation,
continuation-in-part, or reissue application for the foregoing patents,
and any renewals, foreign counterparts, substitutions or extensions
of any of the foregoing.

1.3 The term "EFFECTIVE DATE" shall mean the date, after the execution
 of this Agreement by both parties hereto, on which HITACHI receives the
amount of Seventeen Thousand Five Hundred United States Dollars
(US$17,500) in accordance with Section 3.1(1) of this Agreement, less
any taxes withheld for payment to the Government of the United States in
accordance with Section 3.5.

1.4 "AFFILIATES" means corporations or other entities of which a
party hereto owns or controls directly or indirectly more than fifty
percent (50%) of the voting stock entitled to vote for the election
of the members of the board of directors or persons performing
similar functions, or, in the case of entities not having voting
stock, equivalent ownership or control thereof, provided that such
entity shall be considered an AFFILIATE for only so long as such
ownership or control exists.

2. GRANT OF LICENSE

HITACHI hereby grants to LICENSEE a world-wide, nonexclusive license
under the LICENSED PATENTS, without the right to sublicense, to
produce or "HAVE PRODUCED" LICENSED PRODUCT by a method or apparatus
in


                                      1


   2

accordance with the LICENSED PATENTS, and to use, sell and otherwise 
dispose of LICENSED PRODUCT so produced. LICENSEE shall have the right to
extend the licenses granted hereunder to LICENSEE's AFFILIATES, provided that
LICENSEE provide written notification to HITACHI identifying any such AFFILIATE
prior to extending the licenses granted hereunder to such AFFILIATE, and
provided further that LICENSEE report and submit royalties on behalf of such
AFFILIATES in accordance with Section 3.3 of this Agreement. 

A license to "HAVE PRODUCED" as used herein shall mean a license granted
to LICENSEE to subcontract a third party to produce LICENSED PRODUCT only for
the account of, and for use or resale by, LICENSEE or, to the extent
appropriate, LICENSEE's AFFILIATES. 


3.  COMPENSATION, PAYMENT AND REPORT 

3.1 In consideration of the licenses granted by HITACHI to LICENSEE
under LICENSED PATENTS, LICENSEE shall pay to HITACHI:

(1) a lump sum, non-refundable amount of Seventeen Thousand Five Hundred United
    States Dollars (US$17,500) as an initial fee payable within ten (10)
    days of the execution of this agreement by both parties hereto, which shall
    be creditable against running royalties pursuant to Section 3.1(2) hereof,
    and 

(2) running royalties at the rate of one percent (1.0%) on NET SALES of
    LICENSED PRODUCT used, sold or otherwise disposed of by LICENSEE and
    its AFFILIATES prior to or during the term of this Agreement. 

3.2 For the purpose of this section, NET SALES of LICENSED PRODUCT
shall be determined as follows: 

(1) In respect of LICENSED PRODUCT sold or otherwise commercially
    disposed of in normal, arm's length commercial transactions, NET SALES
    shall be the total sales of LICENSED PRODUCT based on the actual selling
    price at which customers are billed in the usual course of business for
    such LICENSED PRODUCT, without any deductions other than sales or excise
    taxes, if any, and except for rejections or returns. If billed separately,
    the selling price of packing material, boxes, cartons and crates in which
    LICENSED PRODUCT is packed, as well as freight, handling and insurance
    charges and any duties or tariffs, shall not be included in determining NET
    SALES.

(2) If LICENSED PRODUCT is not separately sold or otherwise commercially
    disposed of as it is but instead is incorporated in another product which
    is not itself a LICENSED PRODUCT that is sold or otherwise commercially
    disposed of in a normal, arm's length commercial transaction, then the NET
    SALES of LICENSED PRODUCT shall be determined by multiplying the total
    sales of the product incorporating LICENSED PRODUCT based on the actual
    selling price at  

                                      2


   3

      which customers are billed in the usual course of business for
      such product, times the ratio of the manufacturing cost of the
      LICENSED PRODUCT to the overall manufacturing cost of the
      product incorporating LICENSED PRODUCT.

 (3)  In the event of sale or other commercial disposition of
      LICENSED PRODUCT other than in a normal arm's length commercial
      transaction, or in the event of use or other commercial disposal
      by LICENSEE or its AFFILIATES of LICENSED PRODUCT (except for
      LICENSEE's research and development purposes and except for
      incorporation of LICENSED PRODUCT into another product as set
      forth in Section 3.2(2) above), then the NET SALES for such
      LICENSED PRODUCT shall be calculated based on the average
      selling price of such LICENSED PRODUCT sold in normal, arm's
      length commercial transactions.

3.3 Royalty reports and payments shall be made in accordance with the
following provisions:

 (1)  Within Forty Five (45) days of each semi-annual period ending
      on June 30 and December 31 (hereinafter "SEMI-ANNUAL PERIOD")
      during the term of this Agreement, LICENSEE shall furnish to
      HITACHI a statement of royalty specifying NET SALES and the
      types of LICENSED PRODUCT sold or otherwise commercially
      disposed of by LICENSEE or its AFFILIATES during such
      SEMI-ANNUAL PERIOD and the total amount of royalties accrued
      under Section 3.1(2) (including any such accrued royalties to be
      credited against the initial fee pursuant to Section 3.1(1)
      hereof). At the same time, LICENSEE shall make the payment to
      HITACHI by telegraphic transfer of the amount of the accrued
      royalties which exceeds the balance of the initial fee set forth
      in Section 3.1(1) above, if any. If no royalty is payable or
      accrued during the SEMI-ANNUAL PERIOD, LICENSEE shall report in
      the statement that no royalty is due during such SEMI-ANNUAL
      PERIOD.

  (2)  LICENSEE has conducted a good faith investigation with
       respect to sales of LICENSED PRODUCT sold or otherwise
       commercially disposed of prior to October 12, 1994, and
       LICENSEE has determined based on such good faith investigation
       that the NET SALES of LICENSED PRODUCT prior to such date is
       $37,089. The accrued royalty of $370.89 shall not be paid in
       the form of money to HITACHI, but instead shall reduce the
       running royalty credit pursuant to Section 3.1(1) by this
       amount.

  (3)  Within Forty Five (45) days after the date of expiration of
       this Agreement or the date of the termination in the event of
       early termination of this Agreement, LICENSEE shall furnish to
       HITACHI a final statement of royalty and pay the royalty
       accrued up to the date of such expiration or termination of
       this Agreement.

                                      3

   4

      3.4   All payments to be made by LICENSEE to HITACHI hereunder
      shall be remitted in U.S. dollars by telegraphic transfer to
      the designated bank account of HITACHI. Any payment once made
      by LICENSEE to HITACHI shall in no event be refundable. Any
      bank charges accrued with respect to such payment by LICENSEE's 
      bank in this connection shall be borne and paid by LICENSEE.

      3.5   All taxes imposed as a result of the existence of this
      Agreement or the performance of the parties hereunder shall be
      borne and paid by the party required to do so by applicable
      law; provided, however, that If so required by applicable law
      and relevant income tax treaty, LICENSEE shall withhold the
      amount of income taxes levied by the Government of the United
      States on each payment to be made by LICENSEE to HITACHI
      pursuant to this Agreement, shall promptly effect payment of
      the income taxes to the appropriate tax authorities of the
      Government of the United States and shall submit to HITACHI
      official tax receipts or other evidence issued by said tax
      authorities to LICENSEE. The parties agree to cooperate in good
      faith at HITACHI's request regarding any additional
      documentation or the like that may be required to enable
      HITACHI to support a claim for any national tax credit in
      respect of any such taxes so withheld, provided that HITACHI
      shall be responsible for any material, reasonable,
      out-of-pocket expense incurred by LICENSEE as a result thereof.

      3.6   LICENSEE shall keep complete and accurate records with
      respect to LICENSED PRODUCT for which royalties are or may be
      due and payable under this Agreement. Said records shall be
      kept and available at all reasonable times for a period of (5)
      years following the end of each SEMI-ANNUAL PERIOD for
      inspection of an independent certified public accountant or
      agent selected by HITACHI and reasonably acceptable to
      LICENSEE for the sole purpose of verifying the statements of
      royalty submitted by LICENSEE.

      3.7   LICENSEE shall pay interest to HITACHI upon any and all
      amounts overdue and payable under this Agreement at the rate of
      ten percent (10%) per annum for the period from the due date
      through the date of payment.

      4. TERM AND TERMINATION

      4.1   This Agreement shall become effective on the EFFECTIVE
      DATE and shall remain in full force and effect until the
      expiration date of the last-to-expire of the LICENSED PATENTS.
      This Agreement may be terminated at any time by LICENSEE upon
      sixty (60) days prior written notice to HITACHI, such
      termination to be without prejudice to the rights and
      obligations of the parties through the date of termination,
      and provided that LICENSEE include in such written notice a
      statement of LICENSEE's reasons for so terminating this
      Agreement.

      4.2   In the event of a material breach of this Agreement by
      LICENSEE which is not cured within sixty (60) days after
      written notice thereof is received by LICENSEE, this
      Agreement may be terminated forthwith by further written
      notice to that effect from HITACHI. For the purpose of

   5

this section, "material breach" includes, but is not limited to, a breach

4.3 Should LICENSEE become insolvent or be subject to bankruptcy or winding up
proceedings, or in the event of a sale or transfer by LICENSEE of all or
substantially all of the assets of LICENSEE, or in the event that LICENSEE is
merged into or with a third party, then HITACHI may, by written notice,
terminate this Agreement forthwith.

hereof. Licensee shall have no right to take any action or bring or prosecute
