Supply Agreement dated September 24, 1990, and Carbon Agreement dated December 29, 1999, both as amended (collectively, the "Agreements") Dear Mr. Kramp: Further to our recent discussions, it is in the best interest of ATS Medical, Inc., a Minnesota corporation ("ATS") for the parties to renegotiate and amend certain of the rights and obligations under the Agreements.

Supply Agreement notwithstanding this letter agreement). Said Minimum Purchase Obligation will resume in full on January 2007 in accordance with the attached Schedule 1, notwithstanding anything to the contrary in the O.E.M. Supply Agreement. As a result of the foregoing, the term of the O.E.M. Supply Agreement shall be extended only for the time period necessary for ATS to fulfill its Minimum Purchase Obligation as defined in Schedule 1. 2. The Pricing for a Component Set, adjusted pursuant to Section 3 and Exhibit B of the O.E.M. Supply Agreement, shall be expressly made subject to a maximum price of $1,000.00 per Component Set. 3. ATS hereby grants to CMI, its successors and assigns a security interest* in all of ATS' Inventory, whether now owned or hereafter acquired, together with the products and proceeds thereof. Until terminated, as provided herein or by mutual agreement of ATS and CMI this security interest is granted to secure all material obligations of ATS now or hereafter as owed to CMI under the Agreements.

Upon the occurrence of any default of ATS of its payment or other material obligations under the Agreements and until CMI acknowledges in writing that such default has been cured or waived , CMI will have the remedies of a secured party under the Uniform Commercial Code as enacted in Texas or other applicable law. 5. Section 2.5.4 of the Carbon Agreement shall be amended and restated to read as follows: "4: five million dollars ($5,000,000.00) which shall be deemed fully earned on December 28, 2002, but which shall be due and payable in accordance with ATS' promissory note in the form attached hereto Schedule 2, which note shall be payable to the order of CMI in the original principal amount of $5,000,000 and executed concurrent with this letter agreement." 6.
