This Agreement for the Sale of Goods ("Agreement") made and effective this
January 10, 2000, by and between Beacon Power Corporation, A Massachusetts
Corporation ("Seller") and TLER Associates Ltd., A Bahamas Corporation
("Buyer").

Seller desires to sell to Buyer, and Buyer desires to purchase from Seller,
certain tangible personal property.

NOW, THEREFORE, in consideration of the mutual promises herein contained, the
parties hereto agree as follows:

1.  SALE.

purchase the following tangible personal property (the "Goods"): one hundred
(100), Beacon 2 KWH Flywheel Energy Storage Systems.

2.  PRICE.
Buyer shall pay Seller for the Goods the sum of fifteen thousand dollars
($15,000) for each unit. Buyer shall make payment of the purchase price in full
within thirty (30) days following delivery of the Goods by Seller provided
herein, subject to Buyer's right of inspection as set forth in Section 4 below.
In the event that the purchase price is not timely paid, in addition to its
other remedies, Seller may impose, and Buyer shall pay, a late payment charge
equal to one percent (1%) of the overdue amount each month.

3.  SHIPPING.
Seller shall deliver the goods to a shipper (selected by Buyer) as follows:
Beacon Power Factory, 6D Gill Street, Woburn, MA 01801. Buyer shall be solely
responsible for the expenses associated with shipping. The risk of loss from any
casualty to the Goods, regardless of the cause, shall be upon Buyer upon the

Seller will follow Buyer's requested shipping instructions. If none are
requested, Seller will use it discretion in selecting an appropriate
transportation method.

4.  RIGHT OF INSPECTION.

Within thirty (30) business days after delivery, Buyer must give notice to
Seller of any claim with respect to the condition, quality or grade of the Goods
or non-conformance to this Agreement, specifying the basis of the claim in
detail. Seller may, at its option inspect the Goods at Buyer's facilities to
confirm that the Goods do not conform. Failure of Buyer to comply with these
conditions within the time set forth herein shall constitute irrevocable
acceptance of the Goods by Buyer. In the event the Goods do not conform to this
