Item 2.04. Triggering Events That Accelerate or Increase a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement.

As previously disclosed, on June 29, 2011, Satcon Technology Corporation (the “Company”) entered into a Securities Purchase Agreement pursuant to which it issued in a private placement a $16,000,000 unsecured, subordinated convertible note (the “Note”). On October 4, 2012, the Company received a notice from the noteholder pursuant to Section 4(b) of the Note that an event of default currently exists under the note as a result of the Company’s failure to pay the installment amount due on October 1, 2012 (the “Notice”). Under Section 4(b) of the Note, at any time after the noteholder becomes aware of an event of default, the noteholder may require the Company to redeem all or any portion of the outstanding amounts under the Note by delivering a notice to the Company. The Notice requests that the Company remit a redemption amount equal to approximately $7.5 million, representing 120% of the outstanding principal and accrued and unpaid interest on the Note. The Notice also provides that the noteholder has not limited any of its rights under the Note by delivery of the Notice.

Pursuant to the terms of the Note, the Company is to deliver the redemption amount within five business days of receipt of the Notice, and the Company does not intend to pay the redemption amount within such period. If the Company does not pay the redemption amount within such period, the noteholder may at anytime thereafter have the option, in lieu of receiving the redemption amount, to require the Company to issue a new promissory note to replace the existing Note equal to the redemption amount and having a conversion price equal to the lesser of (i) the conversion price as in effect on the date the noteholder withdraws the prior Notice as to all or any portion of the redemption amount and (ii) 90% of the closing bid price of the Company’s common stock during the period beginning on and including the date on which the Notice was delivered and ending on and including the date on which the Notice was withdrawn.

The Company’s failure to pay the installment amount when due under the Note constitutes an event of default under the Company’s Amended and Restated Credit Agreement, dated as of April 22, 2011, with Silicon Valley Bank (the “Bank”), as amended to date (the “Credit Agreement”), and under the Company’s Venture Loan and Security Agreement with Compass Horizon Funding Company LLC, as amended to date. Under the Credit Agreement, the Bank may elect to terminate any future advances to the Company, to accelerate all amounts understanding under the Credit Agreement, and/or to take any other actions to enforce its rights under the Credit Agreement, but has not done so at this time.
