On June 30, 2009, the Amended and Restated Employment Agreement, dated June 27, 2008 (the "2008 Agreement"), by and between Michael A. McManus, Jr. and MISONIX, INC. (the "Company") expired pursuant to a timely notice of non-renewal delivered to the Company by Mr. McManus. Pursuant to the 2008 Agreement, Mr. McManus was employed by the Company as its President and Chief Executive Officer.

On July 13, 2009 the Company entered into a new Employment Agreement with Michael A. McManus, Jr., the Company's President and Chief Executive Officer (the "Agreement"). The Agreement, effective as of July 1, 2009, has an initial term expiring June 30, 2010 and renews for successive one-year periods thereafter unless terminated by either party not less than ninety (90) days prior to the end of the current term. The Agreement provides for an annual base salary of $275,000, and an annual bonus based on Mr. McManus' achievement of annual goals and objectives as determined by the Compensation Committee of the Company's Board of Directors.

Mr. McManus is entitled under the Agreement to participate in or receive additional benefits. He is entitled to participate in any plans and programs made available to the executive employees of the Company generally.

The Company can terminate the Agreement for cause (including disability) and upon Mr. McManus' death. Mr. McManus can terminate the Agreement for good reason (including a change of control of the Company). If Mr. McManus terminates the Agreement for good reason the Company must pay him an amount equal to two times his total compensation (annual base salary plus bonus) at the highest rate paid during the period of his employment, payable in a lump sum within sixty days of termination of employment.

Mr. McManus has also agreed in the Agreement to an eighteen month post-termination covenant not-to-compete, as well as other customary covenants concerning non-solicitation and non-disclosure of confidential information of the Company.

The terms and conditions of the Agreement are identical to the 2008 Agreement.
