ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT. Effective as of July 28, 2004, ATS Medical Sales, Inc. ("AMSI") and ATS Medical, Inc. (the "Company") entered into a Loan and Security Agreement (the "Agreement") with Silicon Valley Bank (the "Bank"), establishing a secured revolving credit facility for $8.5 million. The credit facility under the Agreement consisted of a $2.5 million three-year term and a two-year $6.0 million line of credit. The credit facility contained two financial covenants: a liquidity ratio and a required minimum tangible net worth. The term loan carries an interest rate of prime plus 1.0% with a minimum of 5.25%. The line of credit carried an interest rate of prime plus 1.5% with a minimum rate of 5.75%. On March 24, 2005, the Company entered into an amendment to the Agreement (the "Amendment No. 1") with the Bank whereby amendments were made to the two financial covenants of the Agreement, effective as of April 1, 2005. On March 29, 2006, the Company entered into another amendment to the Agreement ("Amendment No. 2") whereby the Bank agreed to waive the prohibition set forth in Section 7.3 of the Agreement with respect to the Company's pending acquisition of 3F Therapeutics, Inc., agreed to provide for advances of up to $1,500,000 for the Company to use to finance or refinance eligible equipment, agreed that the maximum aggregate advances under the Agreement could not exceed $8,600,000, and agreed to change the tangible net worth requirements under the Agreement to be at least $40,000,000. On August 15, 2006, the Company entered into another amendment to the Agreement ("Amendment No. 3") whereby the Bank agreed to extend the ending date by which the Company may purchase eligible equipment pursuant to the new $1,500,000 advance amount from May 31, 2006 to October 31, 2006, and agreed to extend the date by which the Company could provide financial statements reflecting the impact of acquisition of 3F Therapeutics, Inc. to the 30 days following the date of the closing of the acquisition. On February 20, 2007, the Company entered into another amendment to the Agreement ("Amendment No. 4") with the Bank whereby the Company and the Bank agreed to amend the Agreement in four respects. First, the committed revolving line of credit under the Agreement was terminated and the Company satisfied its outstanding advances and accrued interest on the revolving line of credit. Second, section 2.1.7 of the Agreement, which addressed maximum aggregate advances under the Agreement, was deleted in its entirety. Third, the unused line fee provided for in Section 2.4(c) of the Agreement was eliminated with respect to future fiscal quarters, and February 15, 2007 was established as the end of the term of the committed revolving line for purposes of the unused line fee. And fourth, amendments were made to the two financial covenants of the Agreement, effective as of December 31, 2006. The Liquidity Ratio was decreased to be equal to or greater than 1.60 to 1.00, and the tangible net worth requirement was eliminated.
