(a) Termination.

As used in this Agreement, an “event of termination” shall mean and include any one or more of the following:


(i) The termination by the Company of Executive’s employment hereunder for any reason other than pursuant to paragraph 6(c); or


(ii) Executive’s resignation from the Company’s employ for Good Reason, upon not less than thirty (30) days’ prior written notice. “Good Reason” means, without the Executive’s written consent, (A) the material diminution of any material duties or responsibilities of the Executive without the same being corrected within ten (10) days after being given written notice thereof; (B) a material reduction in the Executive’s base salary; or (C) the Company giving written notice of its intention not to extend the term of this Agreement as provided in paragraph 3(a).



(b) Continuation of Salary and Other Benefits. Upon the occurrence of an event of termination under paragraph 6(a), the Company (i) shall, subject to the provisions of Section 7 below, pay Executive, or in the event of his subsequent death, his beneficiary or beneficiaries of his estate, as the case may be, as severance pay or liquidated damages, or both, semi-monthly for a period of six (6) months following the event of termination (the “Severance Payment Period”), a sum equal to his current salary in effect at the time of the event of termination, but in no case at a rate less than $240,000 per annum, (ii) shall continue to provide the other benefits referred to in Section 5 hereof until the end of the Severance Payment Period or until Executive becomes employed elsewhere, whichever is earlier, and (iii) shall continue to provide the benefits provided for in paragraph 4(b) to the extent of expenses incurred but not reimbursed prior to the event of termination. Such payments shall commence on the last day of the next regular pay period following the date of the event of termination, or, at the election of the Company, may be paid in one lump sum or in such other installments as may be mutually agreed between the Company and Executive or, in the event of his subsequent death, his beneficiary or beneficiaries or legal representative, as the case may be.


(c) Other Termination of Employment. Notwithstanding paragraphs 6(a) and (b) or any other provision of this Agreement to the contrary, if on or after the date of this Agreement and prior to the end of the term hereof:


(i) Executive has been convicted of any crime or offense constituting a felony under applicable law, including, without limitation, any act of dishonesty such as embezzlement, theft or larceny;


(ii) Executive shall act or refrain from acting in respect of any of the duties and responsibilities which have been assigned to him in accordance with this Agreement and shall fail to desist from such action or inaction within ten (10) days (or such longer period of time, not exceeding ninety (90) days, as Executive shall in good faith and the exercise of reasonable efforts require to desist from such action or inaction) after Executive’s receipt of notice from the Company of such action or inaction and the Board of Directors determines that such action or inaction constituted gross negligence or a willful act of malfeasance or misfeasance of Executive in respect of such duties; or


(iii) Executive shall breach any material term of this Agreement and shall fail to correct such breach within ten (10) days (or such longer period of time, not exceeding ninety (90) days, as Executive shall in good faith and the exercise of reasonable efforts require to cure such breach) after Executive’s receipt of notice from the Company of such breach;


then, and in each such case, the Company shall have the right to give notice of termination of Employee’s services hereunder as of a date (not earlier than fourteen (14) days from such notice) to be specified in such notice and this Agreement (other than the provisions of Section 7 hereof) shall terminate on such date.



7. Post-Termination Obligations. All payments and benefits to Executive under this Agreement shall be subject to Executive’s compliance with the following provisions during the term of his employment and for the Severance Payment Period:


(a) Confidential Information and Competitive Conduct. Executive shall not, to the detriment of the Company, disclose or reveal to any unauthorized person any trade secret or other confidential information relating to the Company or its affiliates or to any businesses operated by them, and Executive confirms that such information constitutes the exclusive property of the Company. Executive shall not otherwise act or conduct himself to the material detriment of the Company or its affiliates, or in a manner which is inimical or contrary to the interests thereof, and shall not, directly or indirectly, engage in, enter the employ of or render any service to any person, firm or business in direct competition with any part of the business being conducted by the Company; provided, however, that Executive’s ownership less than five percent (5%) of the outstanding stock of a corporation shall not be itself be deemed to constitute such competition. Executive recognizes that the possible restrictions on his activities which may occur as a result of his performance of his obligations under this paragraph 7(a) are required for the reasonable protection of the Company and its investments. For purposes hereof, “direct competition” means the pursuit of one or more of the same therapeutic or diagnostic indications utilizing a substantially similar scientific basis.


(b) Failure of Executive to Comply. If, for any reason other than death or disability, Executive shall, without written consent of the Company, fail to comply with the provisions of paragraph 7(a) above, his rights to any future payments or other benefits hereunder shall terminate, and the Company’s obligations to make such payments and provide such benefits shall cease.


(c) Remedies. Executive agrees that monetary damages would not be adequate compensation for any loss incurred by the Company by reason of a breach of the provisions of this Section 7 and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.


8. Effect of Prior Agreements. This Agreement contains the entire understanding between the parties hereto and supersedes any prior employment agreements between the Company and Executive.


9. General Provisions.


(a) Binding Agreement. This Agreement shall be binding upon, and inure to the benefit of, Executive and the Company and their respective permitted successors and assigns.


(b) Legal Expenses. In the event that Executive incurs legal expenses in contesting any provision of this Agreement and such contest results in a determination that the Company has breached any of its obligations hereunder, Executive shall be reimbursed by the Company for such legal expenses.



10. Successors and Assigns.


(a) Assignment by the Company. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company and, unless clearly inapplicable, reference herein to the Company shall be deemed to include its successors and assigns.


(b) Assignment by Executive. Executive may not assign this Agreement in whole or in part.


11. Modification and Waiver.


(a) Amendment of Agreement. This Agreement may not be modified or amended except by an instrument in writing signed by the parties hereto.


(b) Waiver. No term or condition of this Agreement shall be deemed to have been waived except by written instrument of the party charged with such waiver. No such written waiver shall be deemed a continuing waiver unless specifically stated therein, and each such waiver shall operate only as to the specific term or condition waived.


12. Severability. In the event any provision of this Agreement or any part hereof is held invalid, such invalidity shall not affect any remaining part of such provision or any other provision. If any court construes any provision of this Agreement to be illegal, void or unenforceable because of the duration or the area or matter covered thereby, such court shall reduce the duration, area or matter of such provision, and, in its reduced form, such provision shall then be enforceable and shall be enforced.


13. Governing Law. This Agreement has been executed and delivered in the State of California, and its validity interpretation, performance, and enforcement shall be governed by the laws of said State.
