Item 2    Acquisition or Disposition of Assets

     On November 16, 1999, SatCon Technology Corporation (the "Registrant")
purchased certain intellectual property, equipment and other assets from
Northrop Grumman Corporation ("NGC"). These assets were used by NGC in
connection with its power electronics products business. The Registrant intends
to continue to use the acquired assets in its power electronics products
business. The Registrant also entered into (i) a sublease with NGC pursuant to
which it entered into a five-year sublease for approximately 14,863 square feet
of rentable space in the Baltimore, Maryland area and (ii) a three-year
Transition Services Agreement providing the Registrant access to certain test
facilities and personnel of NGC on a fee basis. In consideration for the
foregoing acquisition and agreements, NGC received 578,761 shares of the
Registrant's common stock, $0.01 par value per share (the "Common Stock"), and
warrants to purchase an additional 200,000 shares of the Registrant's Common
Stock. A warrant to purchase 100,000 shares of the Registrant's Common Stock was
issued by the Registrant on November 16, 1999. A second warrant to purchase
100,000 shares of the Registrant's Common Stock will be issued upon the
satisfaction by NGC of certain agreed upon conditions. The warrants each have a
term of six years and an exercise price per share of Common Stock of $9.725.

     The Registrant has agreed to register for resale under the Securities Act
of 1933, as amended (the "Securities Act"), the Common Stock (i) issued in
connection with the transaction and (ii) issuable upon exercise of the warrants.

     The foregoing summary description is qualified in its entirety by reference
to the definitive transaction documents, copies of which are attached as
exhibits to this Current Report on Form 8-K.

     This report may contain forward-looking statements within the meaning of
Section 27A of the Securities Act and Section 21E of the Securities Exchange Act
of 1934, as amended, which reflect the Registrant's current judgment on certain
issues.  Because such statements apply to future events, they are subject to
risks and uncertainties that

                                      -2-
