1.                                      Duties and Scope of Employment.

(a)                                 Positions and Duties. The Company will continue to employ Executive as President and Chief Executive Officer. The Executive will render such business and professional services in the performance of his duties, consistent with Executive’s position within the Company, as will reasonably be assigned to him by the Company’s Board of Directors (the “Board”). The period of Executive’s employment under this Agreement is referred to herein as the “Employment Term.”

(b)                                 Obligations. During the Employment Term, Executive will perform his duties faithfully and to the best of his ability and will devote his full business efforts and time to the Company. For the duration of the Employment Term, Executive agrees not to actively engage in any other employment, occupation or consulting activity for any direct or indirect remuneration without the prior approval of the Board.

2.                                      At-Will Employment. The parties agree that Executive’s employment with the Company will be “at-will” employment and may be terminated at any time with or without cause or notice. Executive understands and agrees that neither his job performance nor promotions, commendations, bonuses or the like from the Company give rise to or in any way serve as the basis for modification, amendment, or extension, by implication or otherwise, of his employment with the Company. However, as described in this Agreement, Executive may be entitled to severance benefits depending on the circumstances of Executive’s termination of employment with the Company.

3.                                      Compensation.

(a)                                 Base Salary. During the Employment Term, the Company will pay Executive an annual salary of [$120,000] as compensation for Executive’s services (the “Base Salary”). The Base Salary will be paid periodically in accordance with the Company’s normal payroll practices and be subject to the usual, required withholdings. Executive’s salary will be subject to review and adjustments will be made based upon the Company’s normal performance review practices.

(b)                                 Restricted Stock Grant. Executive has been granted the right to purchase 1,000,000 shares of Company common stock subject to a stock restriction agreement entered into by and between the Company and Executive, dated July 15, 2010 (the “Restricted Stock Agreement”).

4.                                      Employee Benefits. If and when the Company adopts employee benefit programs, the Executive shall be allowed to participate in Company’s such programs offered to similarly

situated employees. The Company reserves the right to cancel or change the benefit plans and programs it offers to its employees at any time.

5.                                      Expenses. The Company will reimburse Executive for reasonable travel, entertainment or other expenses incurred by Executive in the furtherance of or in connection with the performance of Executive’s duties hereunder, in accordance with the Company’s expense reimbursement policy as in effect from time to time.

6.                                      Acceleration upon Change of Control. Upon a Change of Control, 100% of the unvested shares subject to Executive’s then outstanding Company equity compensation awards shall immediately vest, and with respect to options or stock appreciation rights, become exercisable. In all other respects, the Executive’s Company equity compensation awards shall continue to be bound by and subject to the terms of their respective agreements.

7.                                      Severance.

(a)                                 Termination for other than Cause, Death or Disability Apart from a Change of Control. If prior to a Change of Control or after twelve (12) months following a Change of Control, the Company (or any parent or subsidiary or successor of the Company) terminates Executive’s employment with the Company other than for Cause, death or Disability, then, subject to Section 8, Executive will be entitled to: (i) a lump sum cash payment equal to twelve (12) months of Executive’s then-existing Base Salary, (ii) accelerated vesting of unvested shares subject to Executive’s then outstanding Company equity awards in an amount equal to the number of shares that would have vested had Executive remained employed for an additional twelve (12) months from the date of such termination, and (iii) if Executive elects continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) or comparable state law for Executive and Executive’s eligible dependents (as applicable), within the time period prescribed pursuant to COBRA or such comparable state law, the Company will reimburse Executive for the applicable premiums for such coverage (at the coverage levels in effect immediately prior to Executive’s termination) until the earlier of (A) a period of twelve (12) months from the last date of employment of the Executive with the Company, or (B) the date upon which Executive and/or Executive’s eligible dependents becomes covered under similar plans or are otherwise ineligible for coverage under COBRA or such comparable state law.

(b)                                 Termination for other than Cause, Death or Disability or Resignation by Executive for Good Reason upon or within Twelve Months Following a Change of Control. If upon or within twelve (12) months following a Change of Control (i) the Company (or any parent or subsidiary or successor of the Company) terminates Executive’s employment with the Company other than for Cause, death or Disability, or (ii) the Executive resigns from such employment for Good Reason, then, subject to Section 8, Executive will be entitled to: (A) a lump sum cash payment equal to twelve (12) months of Executive’s then-existing Base Salary and (B) if Executive elects continuation coverage pursuant to the COBRA or comparable state law for Executive and Executive’s eligible dependents (as applicable), within the time period prescribed pursuant to COBRA or such comparable state law, the Company will reimburse Executive for the applicable premiums for such coverage (at the coverage levels in effect immediately prior to Executive’s termination) until the earlier of (1) a period of twelve (12) months from the last date of employment of the Executive with the Company, or (2) the date upon which Executive and/or Executive’s

If Executive’s employment with the Company (or any parent or subsidiary or successor of the Company) terminates voluntarily by Executive (except upon resignation for Good Reason upon or within twelve (12) months following a Change of Control), for Cause by the Company or due to Executive’s death or Disability, then (i) all vesting will terminate immediately with respect to Executive’s outstanding equity awards, (ii) all payments of compensation by the Company to Executive hereunder will terminate immediately (except as to amounts already earned), and (iii) Executive will only be eligible for severance benefits in accordance with the Company’s established policies, if any, as then in effect.

(d)                                 Exclusive Remedy. In the event of a termination of Executive’s employment with the Company (or any parent or subsidiary or successor of the Company), the provisions of this Section 7 are intended to be and are exclusive and in lieu of any other rights or remedies to which Executive or the Company may otherwise be entitled, whether at law, tort or contract, in equity, or under this Agreement. Executive will be entitled to no severance or other benefits upon termination of employment with respect to acceleration of award vesting or severance pay other than those benefits expressly set forth in this Section 7.

8.                                      Conditions to Receipt of Severance; No Duty to Mitigate.

(a)                                 Separation Agreement and Release of Claims. The receipt of any severance pursuant to Section 7(a) or (b) will be subject to Executive signing and not revoking a separation agreement and release of claims in a form reasonably satisfactory to the Company (the “Release”) and provided that such Release becomes effective and irrevocable no later than sixty (60) days following the termination date (such deadline, the “Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, Executive will forfeit any rights to severance or benefits under this Agreement. In no event will severance payments or benefits be paid or provided until the Release becomes effective and irrevocable.

(b)                                 Section 409A.

(i)                             Notwithstanding anything to the contrary in this Agreement, no Deferred Payments will be paid or otherwise provided until Executive has a “separation from service” within the meaning of Section 409A. Similarly, no severance payable to Executive, if any, pursuant to this Agreement that otherwise would be exempt from Section 409A pursuant to Treasury Regulation Section 1.409A-1(b)(9) will be payable until Executive has a “separation from service” within the meaning of Section 409A.

(ii)                          Any severance payments or benefits under this Agreement that would be considered Deferred Payments will be paid on, or, in the case of installments, will not commence until, the sixtieth (60th) day following Executive’s separation from service, or, if later, such time as required by Section 8(b)(iii). Except as required by Section 8(b)(iii), any installment payments that would have been made to Executive during the sixty (60) day period immediately following Executive’s separation from service but for the preceding sentence will be paid to Executive on the

3

sixtieth (60th) day following Executive’s separation from service and the remaining payments shall be made as provided in this Agreement.

(iii)                               Notwithstanding anything to the contrary in this Agreement, if Executive is a “specified employee” within the meaning of Section 409A at the time of Executive’s termination (other than due to death), then the Deferred Payments that are payable within the first six (6) months following Executive’s separation from service, will become payable on the first payroll date that occurs on or after the date six (6) months and one (1) day following the date of Executive’s separation from service. All subsequent Deferred Payments, if any, will be payable in accordance with the payment schedule applicable to each payment or benefit. Notwithstanding anything herein to the contrary, if Executive dies following Executive’s separation from service, but prior to the six (6) month anniversary of the separation from service, then any payments delayed in accordance with this paragraph will be payable in a lump sum as soon as administratively practicable after the date of Executive’s death and all other Deferred Payments will be payable in accordance with the payment schedule applicable to each payment or benefit. Each payment and benefit payable under this Agreement is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations.

(iv)                              Any amount paid under this Agreement that satisfies the requirements of the “short-term deferral” rule set forth in Section 1.409A-1(b)(4) of the Treasury Regulations will not constitute Deferred Payments for purposes of clause (i) above.

(v)                                 Any amount paid under this Agreement that qualifies as a payment made as a result of an involuntary separation from service pursuant to Section 1.409A-1(b)(9)(iii) of the Treasury Regulations that does not exceed the Section 409A Limit (as defined below) will not constitute Deferred Payments for purposes of clause (i) above.

(vi)                              The foregoing provisions and all compensation and benefits provided for under this Agreement are intended to comply with or be exempt from the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder will be subject to the additional tax imposed under Section 409A, and any ambiguities or ambiguous terms herein will be interpreted to be exempt or so comply. The Company and Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to Executive under Section 409A.

(c)                                  Confidential Information Agreement. Executive’s receipt of any payments or benefits under Section 7 will be subject to Executive continuing to comply with the terms of Confidential Information Agreement (as defined in Section 10).

(d)                                 No Duty to Mitigate. Executive will not be required to mitigate the amount of any payment contemplated by this Agreement, nor will any earnings that Executive may receive from any other source reduce any such payment.

(b)                                 Change of Control. For purposes of this Agreement, “Change of Control” of the Company is defined as (a) the acquisition of the Company by another entity by means of any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation or stock transfer, but excluding any such transaction effected primarily for the purpose of changing the domicile of the Company), unless the Company’s stockholders of record immediately prior to such transaction or series of related transactions hold, immediately after such transaction or series of related transactions, at least 50% of the voting power of the surviving or acquiring entity (provided that the sale by the Company of its securities for the purposes of raising additional funds shall not constitute a Change of Control hereunder); or (b) a sale of all or substantially all of the assets of the Company.

For purposes of this Agreement, “Disability” means, in the good faith judgment of the Board, Executive being unable to substantially perform Executive’s duties under this Agreement for not less than 120 work days within a twelve (12) consecutive month period as a result of Executive’s incapacity due to any medically determinable physical or mental impairment.

5

solely by virtue of the Company being acquired and made part of a larger entity (as, for example, when the Chief Executive Officer of the Company remains as such following a Change of Control but is not made the Chief Executive Officer of the acquiring corporation) will not constitute “Good Reason”; (ii) a material reduction in Executive’s Base Salary; provided, however, that a reduction in Executive’s Base Salary of ten percent (10%) or less in any one year will not be deemed a material reduction; or (iii) a material change in the geographic location of Executive’s primary work facility or location; provided, that a relocation of less than thirty (30) miles from Executive’s then present location will not be considered a material change in geographic location.

Any other attempted assignment, transfer, conveyance or other disposition of Executive’s right to compensation or other benefits will be null and void.

13.                               Excise Tax. In the event that the severance and other benefits provided for in this Agreement or otherwise payable to the Executive (i) constitute “parachute payments” within the meaning of Section 280G of the Code, and (ii) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Executive’s benefits under this Agreement shall be either

(1)                                 delivered in full, or

(2)                                 delivered as to such lesser extent which would result in no portion of such benefits being subject to the Excise Tax,

whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt by the Executive on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code.

16.                               Arbitration.

(a)                                 Arbitration. In consideration of Executive’s employment with the Company, its promise to arbitrate all employment-related disputes, and Executive’s receipt of the compensation, pay raises and other benefits paid to Executive by the Company, at present and in the future, Executive 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 their capacity as such or otherwise) arising out of, relating to, or resulting from Executive’s employment with the Company or termination thereof, including any breach of this Agreement, will 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 “Act”), and pursuant to California law. The Federal Arbitration Act shall also apply with full force and effect, notwithstanding the application of procedural rules set forth under the Act.

(b)                                 Dispute Resolution. Disputes that Executive agrees to arbitrate, and thereby agrees to waive any right to a trial by jury, include any statutory claims under local, state, or federal law, including, but not limited to, 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 Sarbanes Oxley Act, the Worker Adjustment and Retraining Notification Act, the California Fair Employment and Housing Act, the Family and Medical Leave Act, the California Family Rights Act, the California Labor Code, claims of harassment, discrimination, and wrongful termination, and any statutory or common law claims. Executive further understands that this Agreement to arbitrate also applies to any disputes that the Company may have with Executive.

(c)                                  Procedure. Executive 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. The arbitrator shall have the power to decide any motions brought by any party to the arbitration, including motions for summary judgment and/or adjudication, motions to dismiss and demurrers, and motions for class certification, prior to any arbitration hearing. The arbitrator shall have the power to award any remedies available under applicable law, and the arbitrator shall award attorneys’ fees and costs to the prevailing party, except as prohibited by law. The Executive understands that the Company will pay for any administrative or hearing fees charged by the arbitrator or AAA except that the Executive shall pay the first $125.00 of any filing fees associated with any arbitration that Executive initiates. Executive agrees that the arbitrator shall administer and conduct any arbitration in accordance with California law, including the California Code of Civil Procedure and the California Evidence Code, and that the arbitrator shall apply substantive and procedural California law to any dispute or claim, without reference to the rules of conflict of law. To the extent that the AAA’s National Rules for the Resolution of Employment Disputes conflict with California law, California law shall take precedence. The decision of the arbitrator shall be in writing.

8

(d)                                 Remedy. Except as provided by the Act and this Agreement, arbitration shall be the sole, exclusive, and final remedy for any dispute between Executive and the Company. Accordingly, except as provided by the Act and this Agreement, neither Executive nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding, the arbitrator will not have the authority to disregard or refuse to enforce any lawful Company policy, and the arbitrator will not order or require the Company to adopt a policy not otherwise required by law which the Company has not adopted.

(e)                                  Availability of Injunctive Relief. In addition to the right under the Act to petition the court for provisional relief, Executive agrees that any party may also petition the court for injunctive relief where either party alleges or claims a violation of this Agreement or the Confidentiality Agreement or any other agreement regarding trade secrets, confidential information, nonsolicitation or Labor Code §2870. In the event either party seeks injunctive relief, the prevailing party will be entitled to recover reasonable costs and attorneys fees.

(f)                                   Administrative Relief. Executive is not prohibited from pursuing an administrative claim with a local, state, or federal administrative body or government agency that is authorized to enforce or administer laws related to employment, including, but not limited to, the Department of Fair Employment and Housing, the Equal Employment Opportunity Commission, the National Labor Relations Board, or the Workers’ Compensation Board. However, Executive may not pursue court action regarding any such claim, except as permitted by law.

(g)                                  Voluntary Nature of Agreement. Executive acknowledges and agrees that Executive is executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else. Executive further acknowledges and agrees that Executive has carefully read this Agreement and that Executive has asked any questions needed for Executive to understand the terms, consequences and binding effect of this Agreement and fully understands it, including that Executive is waiving Executive’s right to a jury trial. Finally, Executive agrees that Executive has been provided an opportunity to seek the advice of an attorney of Executive’s choice before signing this Agreement.
