course of a one-year period; provided, however, that notwithstanding anything in this Agreement to the contrary, if any of the payments described in this Paragraph 3.02 are subject to the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Code Section 409A”) and MakeMusic determines that Executive is a “specified employee” as defined in Code Section 409A as of the date of Executive’s termination of employment, such payments shall not be paid or commence earlier than the first day of the seventh month following the date of Executive’s termination of employment. As a condition to Executive’s receipt of such payments, Executive shall be required to execute, return, comply with and not rescind a full and final release of any and all claims in favor of MakeMusic. Such release agreement shall be prepared by MakeMusic.

     (e) All payments made to Executive under this Paragraph 3.02 shall be reduced by amounts (i) required to be withheld in accordance with federal, state and local laws and regulations in effect at the time of payment, or (ii) owed to MakeMusic by Executive for any amounts advanced, loaned or misappropriated. Such offset shall be made in the manner permitted by and shall be subject to the limitations of all applicable laws, including but not limited to Code Section 409A, and the regulations, notices and other guidance of general applicability issued thereunder.
