engineering design data pertaining to the Product as installed in Buyer's
flywheel system as Buyer requires to complete design, installation in the
flywheel system and testing, and shall support testing by Buyer as required to
assist Buyer in obtaining whatever approvals are needed for commercial sale of

3.       Exclusive Purchase of Buyer's Requirements

         Buyer agrees to purchase Products only from Seller for use in its

         Seller agrees to sell Products [**] only to Buyer, and that it will not
sell Products [**] during the term of this Agreement except to Buyer as long as
Buyer meets the minimum purchase requirements of Article 5 below. If Buyer does
not meet the minimum purchase requirements of Article 5 and Seller intends to
sell Products for use in flywheel systems as provided in Article 5, it shall so
advise Buyer prior to entering any agreement for such sale so that Buyer will
know it is released from its obligations in Article 3.

5.       Minimum Purchase Requirements

         During the term of this Agreement, Buyer's exclusive right to purchase
Products for flywheel systems from Seller, and Seller's agreement to sell

         In the event Buyer fails to purchase the minimum number of Products for
the applicable period, Buyer's exclusive rights with respect to the sale and
distribution of the Products for use in flywheel systems, may, at Seller's
option, become non-exclusive for the remaining term of the Agreement; provided,

specifications, and other data required for manufacture of the Products.

         c) Should the Buyer notify Seller in writing of deficiencies in the
Product and Seller is unable to correct these deficiencies within 30 days,
Seller will deposit into an escrow account, the costs of which will be borne by

            ii) Seller shall have exclusive use of the Inventions for magnetic
                bearings which it manufactures for its customers for
                applications other than flywheels; and

            iii)The Parties shall share equally all royalties earned as a
                result of licensing the Inventions for applications outside of
                the above areas of exclusivity. No licenses shall be granted
                during the term of this Agreement by either Party without
                agreement by the other Party, other than cross-licenses as
                necessary to permit the foregoing exclusive uses.

         b) The Parties shall advise each other seasonally of Inventions as a
result of developing Products they make during the Feasibility Study and
Development Period. Buyer shall be initially responsible for procuring and
paying all costs relating to patents on the Inventions. If Buyer concludes that
any particular Invention does not warrant the cost of obtaining a patent, it
shall so advise Seller who shall then be free to procure a patent on that
Invention.
