Pursuant to the terms of the promissory note dated May 11, 2009, the principal and accrued interest was due and payable to Southwall IG Holdings, Inc. by January 1, 2010. Under terms of the note, in the event of default, the outstanding principal was to be paid in the form of a credit to the Southwall IG Holdings, Inc. capital account. Effective January 1, 2010, Sound Solutions had not paid the principal balance of $300 and was in default of the promissory note.
