                        EXCLUSIVE DISTRIBUTOR AGREEMENT
                        -------------------------------

     WHEREAS LexaLite International Corporation, located in Charlevoix, 
Michigan, (hereinafter referred to as "LEXALITE") wishes to obtain a distributor
to promote the use and handle the sales of its products in the Asian and South 
Pacific markets, and

     WHEREAS Austrasia Banking Corporation, with United States offices located 
in Charlevoix, Michigan, (hereinafter referred to as "AUSTRASIA") is desirous of
becoming an exclusive distributor of LexaLite products in that market place,

     NOW THEREFORE, these two parties enter into this Agreement, which shall 
become effective July 1, 1979.

     IT IS AGREED:

        I. That LEXALITE does herewith appoint AUSTRASIA sole and exclusive
           distributor for LEXALITE Products, materials, or services to the
           territory described below.

       II. That the territory shall consist of Eastern Asia and the South
           Pacific, specifically defined as all market places lying west of the
           International Date Line, south of the 45th N. parallel and east of 
           the 70 degrees E. meridian.

      III. That AUSTRASIA shall purchase and LEXALITE shall sell its products,
           materials and services at mutually agreeable prices which typically
           shall be 10% below any published list price. On open stock products,
           price shall be maximum discount less 10%. Participation products
           shall be at maximum participation level but without additional
           discount. Certain products, such as the 297 Series shall not carry a
           full discount. AUSTRASIA shall pay for all such purchases on terms
           of net 45 days except as otherwise mutually agreed.

       IV. That LEXALITE shall refer any and all orders or inquiries received
           from within the described territory to AUSTRASIA and shall not make 
           direct sales to points within the territory.

        V. That AUSTRASIA shall restrict its sales of LEXALITE proprietary
           products to original equipment manufacturers; this restriction shall
           not apply to LEXALITE services, materials or custom molded products.

       VI. That in consideration of the most favorable pricing offered to
           AUSTRASIA by LEXALITE; AUSTRASIA shall accept all credit risks and
           shall be liable for payment of any LEXALITE products, materials, or
           services purchased by AUSTRASIA regardless of its customers failure
           to pay.

      VII. That this agreement shall remain in effect for a period of three
           years and shall automatically be renewed for a like period on July 1,
           1982, and on each subsequent third anniversary thereof unless
           terminated as provided herein.

     VIII. That either party may terminate this Agreement without cause by
           notice to that effect in writing by registered or certified mail not
           less than six months prior to the end of the then current three year
           term; in which event the Agreement shall terminate at the end of that
           term and there shall be no further obligation of either party unto 
           the other except for payment(s) for products, materials or services
           previously rendered or delivered and for which a payable exists under
           the terms of this Agreement.


 
     IX. That either party may terminate this Agreement for cause by notice to
         that effect in writing by registered or certified mail, stating the
         cause or reason for terminating, given not less than 90 days prior to
         effective date of such termination. On receipt of such notice, the
         other party shall have 60 days in which to remedy the cause or reason
         stated; and if the remedy is satisfactory to the first party, the
         termination notice shall be cancelled. If the other party is unable to
         remedy to the satisfaction of the first party, this Agreement shall
         terminate at midnight on the 90th day following the delivery of said
         notice as evidenced by the delivery receipt for the certified or
         registered notice. The same restriction on further obligation as stated
         in Paragraph VIII shall then apply.

      X. That nothing herein shall act to restrain either party from the normal
         trade in which each is engaged; but it shall instead act to encourage a
         mutually beneficial supplier/distributor relationship also working to
         the benefit of the customer within the described territory by providing
         concentrated and better coverage of the market place at competitive
         prices.

     THIS AGREEMENT is the entire Exclusive Distributor Agreement between the 
two parties hereto and no other Agreements are expressed or implied.
