 WHEREAS, the Company has agreed to accept Employee’s resignation as its
Vice President of Finance and Administration and Chief Financial Officer and his relinquishment of all other officer and director positions with the Company and its affiliates as of June 22, 2004 (the “Resignation Date”); and 

 
 WHEREAS, the Parties wish to resolve any and all disputes, claims,
complaints, grievances, charges, actions, petitions and demands that the Employee may have against the Company, including, but not limited to, any and all claims arising or in any way related to Employee’s employment with or separation from the
Company. 
  
 NOW THEREFORE, in consideration of the promises made
herein, the Parties hereby agree as follows: 
  
 COVENANTS 
  
 1. Consideration.









 (a) Severance Payment. The Company agrees to pay Employee the lump sum equivalent
of two (2) weeks of his base salary (as in effect on the Resignation Date), less applicable withholding, in accordance with the Company’s regular payroll practices. This payment will be made to Employee within five (5) business days after the
Effective Date. 
  
 (b) Consulting.
Commencing on the Resignation Date, Employee will make himself available to serve as a consultant to the Company through September 24, 2004 (the “Consulting Term”), pursuant to the written consulting agreement (the “Consulting
Agreement”), attached hereto as Exhibit A. 
  
 2.
Options. The Parties acknowledge and agree that one hundred eighty three thousand three hundred thirty-three (183,333) shares of Common Stock subject to Option 1 have vested as of the Resignation Date, zero (0) shares of Common Stock subject
to Option 2 have vested as of the Resignation Date, and zero (0) shares of Common Stock subject to Option 3 have vested as of the Resignation Date. The Parties hereby agree that no further shares will vest under the Options from and after the
Resignation Date. The vested portion of Option 1 will remain outstanding following the Resignation Date and will continue to be subject to the terms and conditions of the Plan and the applicable Option Agreement. Option 2 and Option 3 will cease to
exist and be cancelled and Employee will have no further rights with respect to Option 2 and Option 3. The portion of Option 1 that has not vested as of the Resignation Date will cease to exist and be cancelled and Employee will have no further
rights with respect to such unvested portion of Option 1. Employee will continue to be a Service Provider for purposes of the Plan and the Option Agreements, pursuant to the Consulting Agreement. The Company shall provide written notice to Employee
not more than five (5) business days after Employee ceases to be a Service Provider for purposes of the Plan and Option Agreements; provided, however, that the Company shall have no obligation to provide such notice when Employee ceases to be
a Service Provider for purposes of the Plan and Option Agreements because the Consulting Agreement expires by its own terms. Employee acknowledges that if any of the Options have been classified as “incentive stock options” within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended, such Options will convert into nonstatutory stock options three (3) months and one (1) day after the Resignation Date. Furthermore, Employee acknowledges that in the event the
Options are classified as nonstatutory stock options on the date such Options are exercised, the income recognized upon such exercise will be considered wages that must be reported on Employee’s W-2 and applicable tax withholding will be
required. Employee agrees that the Company may refuse to process any such exercise until Employee has made arrangements satisfactory to the Company to satisfy any such withholding obligations. 
  
 3. Benefits. Employee’s health insurance benefits will cease on
June 30, 2004, subject to Employee’s right to continue his health insurance under COBRA. Employee’s participation in all other benefits and incidents of employment will cease on the Resignation Date. Employee will cease accruing employee
benefits, including, but not limited to, vacation time and paid time off, as of the Resignation Date. 
  
 4. Confidential Information. Employee will continue to maintain the confidentiality of all confidential and proprietary information of the Company
and will continue to comply with the terms and conditions of the Confidentiality Agreement between Employee and the Company. Employee 








 will return all of the Company’s property and confidential and proprietary information in his possession to the
Company. 
  
 5. Payment of Salary and Benefits. Employee
acknowledges and represents that the Company has paid all salary, wages, bonuses, accrued vacation, commissions and any and all other benefits due to Employee through the Resignation Date. Employee ceased accruing employee benefits, including, but

agents, investors, shareholders, attorneys, administrators, affiliates, divisions, subsidiaries, predecessor and successor corporations, and assigns (“the Releasees”), from, and agrees not to sue concerning, any claim, duty, obligation or

enforce the arbitration award. The Parties agree that the prevailing party in any arbitration will be awarded its reasonable attorneys’ fees and costs. The Parties hereby agree to waive their right to have any dispute between them resolved
in a court of law by a judge or jury. This paragraph will not prevent either party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the Parties and the subject matter of their dispute
relating to Employee’s obligations under this Agreement and the Confidentiality Agreement.

 B. Nonuse and Nondisclosure. Consultant will not, during or subsequent to the term of this Agreement, (i) use the Confidential Information for any purpose whatsoever other than the performance of the Services on behalf of the Company
or (ii) disclose the Confidential Information to any third party. Consultant agrees that all Confidential Information will remain the sole property of the Company. Consultant also agrees to take all reasonable precautions to prevent any unauthorized
disclosure of such Confidential Information. 
  
 C. Former Client Confidential Information. Consultant agrees that Consultant will not, during the term of this Agreement, improperly use or disclose any proprietary information or trade secrets of any former or current employer of
Consultant or other person or entity with which Consultant has an agreement or duty to keep in confidence information acquired by Consultant, if any. Consultant also agrees that Consultant will not bring onto the Company’s premises any
unpublished document or proprietary information belonging to any such employer, person or entity unless consented to in writing by such employer, person or entity. 








 D. Third Party Confidential Information. Consultant recognizes that the Company
has received and in the future will receive from third parties their confidential or proprietary information subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited
purposes. Consultant agrees that, during the term of this Agreement and thereafter, Consultant owes the Company and such third parties a duty to hold all such confidential or proprietary information in the strictest confidence and not to disclose it
to any person, firm or corporation or to use it except as necessary in carrying out the Services for the Company consistent with the Company’s agreement with such third party. 
  
 E. Return of Materials. Upon the termination of this Agreement, or upon Company’s earlier

 3.
Ownership. 
  
 A.
Assignment. Consultant agrees that all copyrightable material, notes, records, drawings, designs, inventions, improvements, developments, discoveries and trade secrets conceived, discovered, developed or reduced to practice by Consultant,
solely or in collaboration with others, during the term of this Agreement that relate to the products, technology or research and development of the Company, that are created using any facilities, equipment, supplies or trade secret information of
Company or that are created in connection with performing the Services under this Agreement (collectively, “Inventions”), are the sole property of the Company. Consultant also agrees to assign (or cause to be assigned) and hereby
assigns fully to the Company all Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating to all Inventions. 
  
 B. Further Assurances. Consultant agrees to assist Company, or its designee, at the Company’s expense, in every proper way to
secure the Company’s rights in Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating to all Inventions in any and all countries, including the disclosure to the Company of all pertinent
information and data with respect to all Inventions, the execution of all applications, specifications, oaths, assignments and all other instruments that the Company may deem necessary in order to apply for and obtain such rights and in order to

Inventions. Consultant also agrees that Consultant’s obligation to execute or cause to be executed any such instrument or papers shall continue after the termination of this Agreement. 
  
 C. Pre-Existing Materials. Subject to Section 3.A,
Consultant agrees that if, in the course of performing the Services, Consultant incorporates into any Invention developed under this Agreement any pre-existing invention, improvement, development, concept, discovery or other proprietary information
owned by Consultant or in which Consultant has an interest, (i) Consultant will inform Company, in writing before incorporating such invention, improvement, development, concept, discovery or other proprietary information into any Invention, and

 hereby granted a nonexclusive, royalty-free, perpetual, irrevocable, worldwide license to make, have

Invention without Company’s prior written permission. 
  
 D. Attorney-in-Fact. Consultant agrees that, if the Company is unable because of Consultant’s unavailability, dissolution, mental or physical incapacity, or for any other reason, to secure
Consultant’s signature for the purpose of applying for or pursuing any application for any United States or foreign patents or mask work or copyright registrations covering the Inventions assigned to the Company in Section 3.A, then Consultant
hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Consultant’s agent and attorney-in-fact, to act for and on Consultant’s behalf to execute and file any such applications and to do all
other lawfully permitted acts to further the prosecution and issuance of patents, copyright and mask work registrations with the same legal force and effect as if executed by Consultant. 
  
 4. Conflicting Obligations. 
  
 A. Conflicts. Consultant certifies that Consultant has no outstanding agreement or obligation that is
in conflict with any of the provisions of this Agreement or that would preclude Consultant from complying with the provisions of this Agreement. Consultant will not enter into any such conflicting agreement during the term of this Agreement. Subject
to the foregoing, Consultant is permitted to enter into any other employment or independent contracting relationships concurrent with this Agreement. Consultant’s violation of this Section 4.A will be considered a material breach under Section
6.B. 
  
 B. Substantially Similar Designs.

 6. Term and Termination. 
  
 A. Term. The term of this Agreement will begin on
June 22, 2004 and will continue until the earlier of (i) September 24, 2004, or (ii) termination as provided in Section 6.B. 








 B. Termination. Either party may terminate this Agreement upon giving the other
party 14 days’ prior written notice of such termination pursuant to Section 11.E of this Agreement in the event that the other party is in breach of any material provision of this Agreement, which breach is not cured within such notice period.

  
 C. Survival. Upon such termination,
all rights and duties of the Company and Consultant toward each other shall cease except: 
  
 (1) The Company will pay, within 30 days after the effective date of termination, all amounts owing to Consultant for Services completed
and accepted by the Company prior to the termination date and related expenses, if any, submitted in accordance with the Company’s policies and in accordance with the provisions of Section 1 of this Agreement; and 
  
 (2) Section 2 (Confidentiality), Section 3 (Ownership),
Section 4 (Conflicting Obligations), Section 7 (Independent Contractor; Benefits), Section 8 (Indemnification), Section 9 (Nonsolicitation) and Section 10 (Arbitration and Equitable Relief) will survive termination of this Agreement. 
  
 7. Independent Contractor; Benefits. 
  
 A. Independent Contractor. It is the express
intention of the Company and Consultant that Consultant perform the Services as an independent contractor to the Company. Nothing in this Agreement shall in any way be construed to constitute Consultant as an agent, employee or representative of the
Company. Without limiting the generality of the foregoing, Consultant is not authorized to bind the Company to any liability or obligation or to represent that Consultant has any such authority. Consultant agrees to furnish (or reimburse the Company
for) all tools and materials necessary to accomplish this Agreement and shall incur all expenses associated with performance, except as expressly provided in Exhibit A. Consultant acknowledges and agrees that Consultant is obligated to report
as income all compensation received by Consultant pursuant to this Agreement. Consultant agrees to and acknowledges the obligation to pay all self-employment and other taxes on such income. 
  
 B. Benefits. The Company and Consultant agree that
Consultant will receive no Company-sponsored benefits from the Company. If Consultant is reclassified by a state or federal agency or court as Company’s employee, Consultant will become a reclassified employee and will receive no benefits from
the Company, except those mandated by state or federal law, even if by the terms of the Company’s benefit plans or programs of the Company in effect at the time of such reclassification, Consultant would otherwise be eligible for such benefits.

  
 8. Indemnification. Consultant agrees to indemnify and
hold harmless the Company and its directors, officers and employees from and against all taxes, losses, damages, liabilities, costs and expenses, including attorneys’ fees and other legal expenses, arising directly or indirectly from or in
connection with (i) any negligent, reckless or intentionally wrongful act of Consultant or Consultant’s assistants, employees or agents, (ii) any breach by the Consultant or Consultant’s assistants, employees or agents of any of the
covenants contained in this Agreement, (iii) any failure of Consultant to perform the Services in accordance with all applicable laws, rules and regulations, 








 or (iv) any violation or claimed violation of a third party’s rights resulting in whole or in part
from the Company’s use of the work product of Consultant under this Agreement. 
  
 9. Nonsolicitation. From the date of this Agreement until 12 months after the termination of this Agreement (the “Restricted Period”), Consultant will not, without the Company’s prior
written consent, directly or indirectly, solicit or encourage any employee or contractor of the Company or its affiliates to terminate employment with, or cease providing services to, the Company or its affiliates. During the Restricted Period,
Consultant will not, whether for Consultant’s own account or for the account of any other person, firm, corporation or other business organization, intentionally interfere with any person who is or during the period of Consultant’s
engagement by the Company was a partner, supplier, customer or client of the Company or its affiliates. 
  
 10. Arbitration and Equitable Relief. 
  
 A. Arbitration. Consultant agrees that any and all controversies, claims or disputes with anyone (including the Company and any
employee, officer, director, shareholder or benefit plan of the Company, in its capacity as such or otherwise) arising out of, relating to or resulting from Consultant’s performance of the Services under this Agreement or the termination of
this Agreement, including any breach of this Agreement, shall be subject to binding arbitration under the Arbitration Rules set forth in California Code of Civil Procedure Section 1280 through 1294.2, including Section 1283.05 (the
“Rules”) and pursuant to California law. CONSULTANT AGREES TO ARBITRATE, AND THEREBY AGREES TO WAIVE ANY RIGHT TO A TRIAL BY JURY WITH RESPECT TO, ALL DISPUTES ARISING FROM OR RELATED TO THIS AGREEMENT, INCLUDING BUT NOT LIMITED TO:
ANY STATUTORY CLAIMS UNDER STATE OR FEDERAL LAW, CLAIMS UNDER TITLE VII OF THE CIVIL RIGHTS ACT OF 1964, THE AMERICANS WITH DISABILITIES ACT OF 1990, THE AGE DISCRIMINATION IN EMPLOYMENT ACT OF 1967, THE OLDER WORKERS BENEFIT PROTECTION ACT, THE
CALIFORNIA FAIR EMPLOYMENT AND HOUSING ACT, THE CALIFORNIA LABOR CODE, CLAIMS OF HARASSMENT, DISCRIMINATION OR WRONGFUL TERMINATION AND ANY STATUTORY CLAIMS. Consultant understands that this Agreement to arbitrate also applies to any disputes that
the Company may have with Consultant. 
  
 B.
Procedure. Consultant agrees that any arbitration will be administered by the American Arbitration Association (“AAA”), and that a neutral arbitrator will be selected in a manner consistent with its National Rules for the
Resolution of Employment Disputes. Consultant agrees that the arbitrator will have the power to decide any motions brought by any party to the arbitration, including discovery motions, motions for summary judgment and/or adjudication and motions to
dismiss and demurrers, prior to any arbitration hearing. Consultant agrees that the arbitrator will issue a written decision on the merits. Consultant also agrees that the arbitrator will have the power to award any remedies, including
attorneys’ fees and costs, available under applicable law. Consultant understands that the Company will pay for any administrative or hearing fees charged by the arbitrator or AAA, except that Consultant shall pay the first $200.00 of any
filing fees associated with any arbitration Consultant initiates. Consultant agrees that the arbitrator will administer and conduct any arbitration in a manner consistent with the Rules and that, to the extent that the AAA’s 








 National Rules for the Resolution of Employment Disputes conflict with the Rules, the Rules will take
precedence. 
  
 C. Remedy. Except as
provided by the Rules, arbitration will be the sole, exclusive and final remedy for any dispute between the Company and Consultant. Accordingly, except as provided for by the Rules, neither the Company nor Consultant will be permitted to pursue
court action regarding claims that are subject to arbitration. Notwithstanding the foregoing, the arbitrator will not have the authority to disregard or refuse to enforce any lawful Company policy, and the arbitrator shall not order or require the
Company to adopt a policy not otherwise required by law which the Company has not adopted. 
  
 D. Availability of Injunctive Relief. In addition to the right under the Rules to petition the court for provisional relief,
Consultant agrees that any party may also petition the court for injunctive relief where either party alleges or claims a violation of Sections 2 (Confidentiality), 3 (Ownership) or 4 (Conflicting Obligations) of this Agreement or any other
agreement regarding trade secrets, confidential information, nonsolicitation or Labor Code §2870. In the event either the Company or Consultant seeks injunctive relief, the prevailing party will be entitled to recover reasonable costs and
attorneys’ fees. 
  
 E. Administrative
Relief. Consultant understands that this Agreement does not prohibit Consultant from pursuing an administrative claim with a local, state or federal administrative body such as the Department of Fair Employment and Housing, the Equal Employment
Opportunity Commission or the workers’ compensation board. This Agreement does, however, preclude Consultant from pursuing court action regarding any such claim. 
  
 F. Voluntary Nature of Agreement. Consultant acknowledges and agrees that Consultant is executing
this Agreement voluntarily and without any duress or undue influence by the Company or anyone else. Consultant further acknowledges and agrees that Consultant has carefully read this Agreement and has asked any questions needed to understand the
terms, consequences and binding effect of this Agreement and fully understand it, including that Consultant is waiving its right to a jury trial. Finally, Consultant agrees that Consultant has been provided an opportunity to seek the advice of an
attorney of its choice before signing this Agreement. 
  
 11.
Miscellaneous. 
  
 A. Governing
Law. This Agreement shall be governed by the laws of California without regard to California’s conflicts of law rules.
