COMPENSATION AGREEMENTS Michael D. Dale has served as our President and Chief Executive Officer since October 2002 pursuant to an employment agreement dated September 18, 2002. Mr. Dale's initial annual base salary under the agreement was $250,000, which was increased to $270,000 in 2004. In 2005, the board of directors increased Mr. Dale's salary to $350,000. The board of directors granted a bonus of $77,788 to Mr. Dale, which was paid to him in February 2006, as reward for achievement of certain individual goals and company performance objectives based on net sales and operating income (loss) established by the board of directors. The employment agreement may be terminated at will by either party, provided that if we terminate the agreement without cause, Mr. Dale would be entitled to a severance payment equal to twelve months salary. The agreement also contains a non-competition obligation pursuant to which Mr. Dale agrees not to compete with us during the term of the agreement and for a period of one year following its termination. CHANGE IN CONTROL AGREEMENTS We are entering into agreements with our officers providing for the payment of certain benefits to the officers if their employment terminates following a "change in control" of ATS Medical. The agreements provide for benefits if an officer's employment is terminated within 24 months following a change in control unless such termination was by us for cause, by the officer other than for "good reason," or because of the officer's death. "Good reason" is defined as the termination of employment as a result of either a diminution in the officer's responsibilities, a reduction in salary or benefits, or a relocation of our office of more than 35 miles. A "change in control" is generally defined as an acquisition of more than 35% of our outstanding common stock by any person or group, the merger or sale of ATS Medical or the replacement of a majority of our board of directors with directors not recommended by the existing board of directors. The agreements provide for lump sum payments following 5 termination in amounts equal to two times the officer's base salary, as limited by Section 280G of the Internal Revenue Code of 1986, as amended. In addition, we will provide such officer with health and dental benefits for up to 24 months following termination. If there had been a change in control of ATS Medical as of the end of 2005 and the employment of the executive officers named in the Summary Compensation Table had been immediately terminated, Messrs. Dale, Judd, Curtis and Sportsman and Ms. Ajamil would have been entitled to receive, pursuant to the terms of the agreements, lump sum payments upon termination of $700,000, $339,200, $407,916, $496,124 and $430,000, respectively. COMPENSATION OF DIRECTORS We pay each of our directors $15,000 as an annual retainer, payable quarterly, for service on our board of directors. An additional $5,000 annual retainer, payable quarterly, is paid to the chairs of the Audit Committee and the Personnel and Compensation Committee. In addition, directors are paid $1,000 for each board meeting attended in person and $500 for each board meeting attended telephonically. Audit committee members are paid an additional $500 for each meeting of the Audit Committee attended. We also reimburse our directors for travel-related expenses. Upon their initial election to the board of directors, each outside director receives an option to purchase 5,000 shares of our common stock at the fair market value on the date of election under the 2000 Stock Incentive Plan.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS None. 8 ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES Ernst & Young LLP, our independent registered public accounting firm, provides both audit and non-audit services to us. The fee table below reports fees billed or to be billed to us for professional services provided to us during 2005 and 2004. Based in part on its review of the nature and value of services provided by Ernst & Young LLP, our Audit Committee has concluded that the provision of non-audit services is compatible with maintaining Ernst & Young LLP's independence. The Audit Committee has approved, pursuant to its pre-approval policies described below, 100% of the services listed below. <Table> <Caption> 2005 2004 ------------------ ------------------ Audit Fees (1) $ 320,000 $ 276,740 Audit-Related Fees $ 0 $ 0 Tax Fees (2) $ 0 $ 53,750 All Other Fees $ 0 $ 0 ------------------ ------------------ Total Fees $ 320,000 $ 330,490 ================== ================== </Table> - -------------------- (1) The increase in audit fees from 2004 to 2005 was due primarily to audit work relating to our internal control over financial reporting, as required by the Sarbanes-Oxley Act of 2002. (2) Tax fees for 2004 were for tax consulting and compliance services. All services provided by our independent registered public accounting firm, Ernst & Young LLP, are subject to pre-approval by our Audit Committee. The Audit Committee has authorized the Chair of the Audit Committee to approve services by Ernst & Young LLP in the event there is a need for such approval prior to the next Audit Committee meeting. However, a full report of any such interim approvals must be given at the next Audit Committee meeting. Before granting any approval, the Audit Committee (or the Committee Chair, if applicable) must receive: (1) a detailed description of the proposed service; (2) a statement from management as to why they believe Ernst & Young LLP is best qualified to perform the service; and (3) an estimate of the fees to be incurred. Before granting any approval, the Audit Committee (or the committee Chair, if applicable) gives due consideration to whether approval of the proposed service will have a detrimental impact on Ernst & Young LLP's independence.
