Executive. The parties hereto agree that Executive is obligated under this Agreement to render personal services of a special, unique, unusual, extraordinary and intellectual character, thereby giving this Agreement special value. Executive’s rights and obligations under this Agreement shall not be transferable by Executive by assignment or otherwise, and any purported assignment, transfer or delegation thereof shall be void; provided, however, that if Executive shall die, all amounts then payable to Executive hereunder shall be paid in accordance with the terms of this Agreement to Executive’s estate.

In exchange for the payments and benefits promised to Executive in this Agreement, Executive agrees as follows:

[[Organization A:Organization]] hereby employs Executive as a Managerial Employee. Executive’s employment is at will. As an at-will Employee, the Executive has the right to voluntarily terminate his/her employment at any time, and with or without advance notice, subject to the terms and conditions herein in this Agreement. [[Organization A:Organization]] also has the option to involuntarily terminate the Executive’s employment at any time, with or without cause, and with or without advance notice, subject to the terms and conditions herein in this Agreement.

Executive Acknowledgments. The Executive acknowledges and agrees that # any and all loyalty obligations arising under Paragraph 18 were discussed with, and accepted by, the Executive prior to the commencement of the Executive’s employment as Executive Vice President and Chief Financial Officer; # the loyalty obligations arising under Paragraph 18 constitute a material inducement to the Company to enter into this Agreement and to agree to employ the Executive on the terms and conditions stated herein; # the loyalty obligations arising under Paragraph 18 are reasonable in time, territory, and scope, and in all other respects; # should any part or provision of any covenant be held invalid, void, or unenforceable in any court of competent jurisdiction, such invalidity, voidness, or unenforceability shall not render invalid, void, or unenforceable any other part or provision of this Agreement; and # if any portion of the foregoing provisions is found to be invalid or unenforceable by a court of competent jurisdiction because its duration, territory, definition of activities, or definition of information covered is considered to be invalid or unreasonable in scope, the invalid or unreasonable terms shall be redefined to carry out the Executive’s and the Company’s intent in agreeing to these restrictive covenants. These restrictive covenants shall be construed as agreements independent of any other provision in this Agreement and the existence of any claim or cause of action of the Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the loyalty obligations arising under Paragraph 18.

The Company may require that Executive not come to work during the notice period and may assign one or more of Executive’s duties and authority to one or more other individuals.
