          5.     PROTECTION OF THE COMPANY’S INTEREST

          (a)     Employee Confidential Information and Invention Agreement. The Employee hereby acknowledges that he has executed and delivered to the Company, contemporaneously with the execution and delivery of this Agreement, the Company’s Employee Confidential Information and Invention Agreement (the "Confidentiality Agreement”), which is attached hereto as Annex A. The Employee hereby acknowledges and

understands that the provisions of the Confidentiality Agreement are incorporated into this Agreement.

          (b)     Protection of Trade Secrets; Non-Solicitation.

          (i)     The Employee acknowledges that in the course of his employment with the Company, he has and will in the course of his continued employment with the Company become familiar with the trade secrets of the Company and its affiliates and with other Confidential Information (as defined in the Confidentiality Agreement) concerning the business of the Company and its affiliates and that his services have been and will be of special, and unique and extraordinary value to the Company and its affiliates. Because of the foregoing and in further consideration of the compensation and other benefits to be provided to the Employee hereunder, the Employee hereby agrees that, during the Term, and at any time thereafter, he shall not, directly or indirectly, use trade secrets (as such term is defined in Section 3426(1)(d) of the Uniform Trade Secrets Act) of the Company or its affiliates or Confidential Information or otherwise engage in unfair competition against the Company or any of its affiliates.

          (ii)     During the Term, and continuing through the first anniversary of the termination date of the Employee’s employment for any reason (the “Restricted Period”), the Employee shall not directly or indirectly through another person or entity induce or attempt to induce any customer, supplier, licensee, licensor, franchisee or other business relation of the Company or any such affiliate that is within any geographical area in which the Company or its affiliates engage or plan to engage in such businesses to cease doing business with the Company or such affiliate or in any way interfere with the relationship between any such customer, supplier, licensee or business relation and the Company or any such affiliate.

          (c)     Extension of Time of Restrictions. The Restricted Period shall be extended by the length of any period during which the Employee is in breach of the restrictions set forth in Section 5(b).

          (d)     Non-Disparagement. The Employee agrees that at any time during his employment with the Company or at any time thereafter, the Employee shall not make, or cause or assist any other person to make, any statement or other communication which impugns or attacks, or is otherwise critical of, the reputation, business or character of the Company, any subsidiary or any of their respective officers, directors, employees, products or services.

          (e)     Enforcement. The Employee hereby acknowledges that he has carefully reviewed the provisions of this Agreement and agrees that the provisions are fair and equitable, and that they are necessary and reasonable in order to protect the Company and its affiliates in the conduct of their business. However, in light of the possibility of differing interpretations of law and change in circumstances, the parties hereto agree that if any one or more of the provisions of this Section 5 (including any provision contained in the Confidentiality Agreement) is determined by a court or other tribunal of competent jurisdiction to be invalid, void or unenforceable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable or enforceable under such circumstances shall be substituted for the stated period, scope or area.

          (f)     Remedies. The Employee acknowledges that the Company has a compelling business interest in preventing unfair competition stemming from the intentional or inadvertent use or disclosure of the Company’s confidential and proprietary information, including trade secrets of the Company. The Employee further acknowledges and agrees that damages for a breach or threatened breach of any of the covenants set forth in this Section 5 (including any provision contained in the Confidentiality Agreement) will be difficult to determine and will not afford a full and adequate remedy, and therefore agrees that the Company, in addition to seeking actual damages in connection therewith and the termination of the Company’s obligations in Section 4(b), may seek specific enforcement of any such covenant in any court of competent jurisdiction, including, without limitation, by the issuance of a temporary or permanent injunction without the necessity of showing any actual damages or posting any bond or furnishing any other security, and that the specific enforcement of the provisions of this Agreement will not diminish the Employee’s ability to earn a livelihood or create or impose upon the Employee any undue hardship. The Employee also agrees that any request for such relief by the Company shall be in addition to, and without prejudice to, any claim for monetary damages that the Company may elect to assert.

          6.     GENERAL PROVISIONS

          (a)     No Other Severance Benefits. Except as specifically set forth in this Agreement, the Employee covenants and agrees that he shall not be entitled to any other form of severance benefits from the Company, including, without limitation, benefits otherwise payable under the Company’s regular severance policies, if any, in the event his employment hereunder ends for any reason and, except with respect to obligations of the Company expressly provided for herein, the Employee unconditionally releases the Company and its subsidiaries and affiliates, and their respective directors, officers, employees and stockholders, or any of them, from any and all claims, liabilities or obligations under any severance arrangements of the Company or any of its subsidiaries or affiliates.

          (b)     Tax Withholding. All amounts paid to Employee hereunder shall be subject to all applicable federal, state and local wage withholding.

          (d) Representation by the Employee.

Breach of this representation will render all of the Company’s obligations under this Agreement void ab initio.

          (e) Assignment; Assumption of Agreement. No right, benefit or interest hereunder shall be subject to assignment, encumbrance, charge, pledge, hypothecation or setoff by the Employee in respect of any claim, debt, obligation or similar process. The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company to assume expressly and to agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place.

          (f) Amendment. No provision of this Agreement may be amended, modified, waived or discharged unless such amendment, modification, waiver or discharge is agreed to in writing and signed by the parties. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time.

          (g) Severability. If any term or provision hereof is determined to be invalid or unenforceable in a final court or arbitration proceeding, (i) the remaining terms and provisions hereof shall be unimpaired and (ii) the invalid or unenforceable term or provision shall be deemed replaced by a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision.

          (h) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California (determined without regard to the choice of law provisions thereof).

          (i) Entire Agreement. This Agreement and the Confidentiality Agreement contain the entire agreement of the Employee, the Company and any predecessors or affiliates

     thereof with respect to the subject matter hereof and all prior agreements and negotiations are superceded hereby.

          (j) Counterparts. This Agreement may be executed by the parties hereto in counterparts, each of which shall be deemed an original, but both such counterparts shall together constitute one and the same document.

          (k) Survival. The provisions of Section 5 (including the provisions of the Confidentiality Agreement) shall survive the termination of this Agreement.

          IN WITNESS WHEREOF, the parties have executed this Agreement, effective as of the day and year first written above.
