Employee's employment with or separation from the Company.

NOW, THEREFORE, in consideration of the mutual promises made herein, the Company
and Employee hereby agree as follows:

--------------------------------------------------------------------------------

COVENANTS

1.    Intentionally Omitted.

2.    Severance. The Parties acknowledge and agree that Section 1 of the
Severance Agreement, and not Section 2, applies to Employee's departure from the
Company, which the Parties hereby agree is “termination by the Company for other
than Good Cause,” as described and defined in the Severance Agreement.

a.
Employee acknowledges that salary for the then current payroll period at the
Separation Date and accrued vacation/paid time off at the Separation Date was
paid by check dated the Separation Date.

b.
In order to further implement the Severance Agreement, Company agrees to pay
Employee cash in the sum of three hundred sixty-four thousand five hundred
dollars ($364,500), less applicable withholdings, promptly after the Effective
Date (as defined in Section 27 hereof) (the “Severance Payment”) but in no event
later than ten (10) days after the Effective Date. The Severance Payment
comprises one year's then current base salary of Employee at the Separation
Date, after taking into account the voluntary 10% reduction in such salary taken
by Employee and the additional 10% reduction in such salary imposed by the
Company's furlough program;

c.
In addition, in accordance with the Severance Agreement, Company agrees to
reimburse Employee for the payments Employee makes for COBRA coverage for
Employee and his dependents for a period of twelve (12) months after the
Separation Date, or until Employee has secured other employment, whichever
occurs first, provided Employee timely elects and pays for continuation coverage
pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as
amended (“COBRA”), within the time period prescribed pursuant to COBRA (“COBRA
Reimbursements”). COBRA Reimbursements shall be made by the Company to Employee
consistent with the Company's normal expense reimbursement policy, provided that
Employee submits documentation to the Company substantiating his payments for
COBRA coverage. Notwithstanding the foregoing, if the Company determines in its
sole discretion that it cannot provide the COBRA Reimbursements without
violating applicable law (including, without limitation, Section 2716 of the
Public Health Service Act), the Company shall in lieu thereof provide Employee a
taxable lump sum payment, within fifteen (15) calendar days following the
Separation Date, in an amount equal to the total COBRA premium that Employee
would be required to pay to continue Employee's group health plan coverage under
COBRA at the rate in effect on the date of the Separation Date.

3.    Benefits. Employee's health insurance benefits ceased on February 28,
2013, subject to Employee's right to continue his health insurance under COBRA.
Employee's participation in all benefits and incidents of employment, including,
but not limited to, vesting in stock options, and the accrual of bonuses,
vacation, and paid time off, ceased as of the Separation Date.

4.    Payment of Salary and Receipt of All Benefits. Employee acknowledges and
represents that, other than the consideration set forth in this Agreement, and
any unreimbursed expenses incurred on behalf of the Company and in accordance
with the Company's normal and customary expense reimbursement policies (which
expenses, if any, will be paid after the Company's receipt of required
documentation), the Company has paid or provided all salary, wages, bonuses,
accrued vacation/paid time off, sabbaticals, premiums, leaves, housing
allowances, relocation costs, interest, severance, outplacement costs, fees,
reimbursable expenses, commissions, stock, stock options, vesting, and any and
all other benefits and compensation due to Employee.

5.    Release of Claims. Employee agrees that the foregoing consideration
represents settlement in full of all outstanding obligations owed to Employee by
the Company and its current and former officers, directors, employees, agents,
investors, attorneys, shareholders, administrators, affiliates, benefit plans,
plan administrators, insurers, trustees, divisions, and subsidiaries, and
predecessor and successor corporations and assigns (collectively, the
“Releasees”). Employee, on his own behalf and on behalf of his respective heirs,
family members, executors, agents, and assigns, hereby and forever

--------------------------------------------------------------------------------

releases the Releasees from, and agrees not to sue concerning, or in any manner
to institute, prosecute, or pursue, any claim, complaint, charge, duty,
obligation, demand, or cause of action relating to any matters of any kind,
whether presently known or unknown, suspected or unsuspected, that Employee may
possess against any of the Releasees arising from any omissions, acts, facts, or
damages that have occurred up until and including the Effective Date of this
Agreement, including, without limitation:

a.    any and all claims relating to or arising from Employee's employment
relationship with the Company and the termination of that relationship;

b.    any and all claims relating to, or arising from, Employee's right to
purchase, or actual purchase of shares of stock of the Company, including,
without limitation, any claims for fraud, misrepresentation, breach of fiduciary
duty, breach of duty under applicable state corporate law, and securities fraud
under any state or federal law;

c.    any and all claims for wrongful discharge of employment; termination in
violation of public policy; discrimination; harassment; retaliation; breach of
contract, both express and implied; breach of covenant of good faith and fair
dealing, both express and implied; promissory estoppel; negligent or intentional
infliction of emotional distress; fraud; negligent or intentional
misrepresentation; negligent or intentional interference with contract or
prospective economic advantage; unfair business practices; defamation; libel;
slander; negligence; personal injury; assault; battery; invasion of privacy;
false imprisonment; conversion; and disability benefits;

d.    any and all claims for violation of any federal, state, or municipal
statute, including, but not limited to, Title VII of the Civil Rights Act of
1964; the Civil Rights Act of 1991; the Rehabilitation Act of 1973; the
Americans with Disabilities Act of 1990; the Equal Pay Act; the Fair Labor
Standards Act; the Fair Credit Reporting Act; the Age Discrimination in
Employment Act of 1967; the Older Workers Benefit Protection Act; the Employee
Retirement Income Security Act of 1974; the Worker Adjustment and Retraining
Notification Act; the Family and Medical Leave Act; the Sarbanes-Oxley Act of
2002; the California Family Rights Act; the California Labor Code; the
California Workers' Compensation Act; and the California Fair Employment and
Housing Act;

e.    any and all claims for violation of the federal or any state constitution;

f.    any and all claims arising out of any other laws and regulations relating
to employment or employment discrimination;

g.    any claim for any loss, cost, damage, or expense arising out of any
dispute over the nonwithholding or other tax treatment of any of the proceeds
received by Employee as a result of this Agreement; and

h.    any and all claims for attorneys' fees and costs.

Employee agrees that the release set forth in this section shall be and remain
in effect in all respects as a complete general release as to the matters
released. This release does not extend to any obligations incurred under this
Agreement. This release does not release claims that cannot be released as a
matter of law, including, but not limited to, Employee's right to file a charge
with or participate in a charge by the Equal Employment Opportunity Commission,
or any other local, state, or federal administrative body or government agency
that is authorized to enforce or administer laws related to employment, against
the Company (with the understanding that any such filing or participation does
not give Employee the right to recover any monetary damages against the Company;
Employee's release of claims herein bars Employee from recovering such monetary
relief from the Company). Employee represents that he has made no assignment or
transfer of any right, claim, complaint, charge, duty, obligation, demand, cause
of action, or other matter waived or released by this Section.

Notwithstanding anything contained in this Agreement to the contrary, Employee
does not waive or release, nor shall anything herein be construed as a waiver or
release by Employee of any rights Employee has or may have, to indemnification
by the Company, including but not limited to any rights to indemnification set
forth in the articles of incorporation, bylaws or other similar documents or
Section 2802 of the California Labor Code or pursuant to any policies of
insurance covering directors and officers for periods prior to the Separation
Date.

6.    Acknowledgment of Waiver of Claims under ADEA. Employee acknowledges that
he is waiving and releasing any rights he may have under the Age Discrimination
in Employment Act of 1967 ("ADEA"), and that this waiver and release is knowing
and voluntary. Employee agrees that this waiver and release does not apply to
any rights or claims

--------------------------------------------------------------------------------

that may arise under the ADEA after the Effective Date of this Agreement.
Employee acknowledges that the consideration given for this waiver and release
is in addition to anything of value to which Employee was already entitled.
Employee further acknowledges that he has been advised by this writing that: (a)
he should consult with an attorney prior to executing this Agreement; (b) he has
twenty-one (21) days within which to consider this Agreement; (c) he has seven
(7) days following his execution of this Agreement to revoke this Agreement; (d)
this Agreement shall not be effective until after the revocation period has
expired; and (e) nothing in this Agreement prevents or precludes Employee from
challenging or seeking a determination in good faith of the validity of this
waiver under the ADEA, nor does it impose any condition precedent, penalties, or
costs for doing so, unless specifically authorized by federal law. In the event
Employee signs this Agreement and returns it to the Company in less than the
21-day period identified above, Employee hereby acknowledges that he has freely
and voluntarily chosen to waive the time period allotted for considering this
Agreement. Employee acknowledges and understands that revocation must be
accomplished by a written notification to the person executing this Agreement on
the Company's behalf that is received prior to the Effective Date. The parties
agree that changes, whether material or immaterial, do not restart the running
of the 21-day period.

7.    California Civil Code Section 1542. Employee acknowledges that he has been
advised to consult with legal counsel and is familiar with the provisions of
California Civil Code Section 1542, a statute that otherwise prohibits the
release of unknown claims, which provides as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR
SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH
IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH
THE DEBTOR.

Employee, being aware of said code section, agrees to expressly waive any rights
he may have thereunder, as well as under any other statute or common law
principles of similar effect.

8.    No Pending or Future Lawsuits. Employee represents that he has no
lawsuits, claims, or actions pending in his name, or on behalf of any other
person or entity, against the Company or any of the other Releasees. Employee
also represents that he does not intend to bring any claims on his own behalf or
on behalf of any other person or entity against the Company or any of the other
Releasees.

9.    Application for Employment. Employee understands and agrees that, as a
condition of this Agreement, Employee shall not be entitled to any employment
with the Company after the Separation Date, and Employee hereby waives any
right, or alleged right, of employment or re- employment with the Company.

10.    Trade Secrets and Confidential Information/Company Property. Employee
reaffirms and agrees to observe and abide by the terms of the Confidentiality
Agreement, specifically including the provisions therein regarding nondisclosure
of the Company's trade secrets and confidential and proprietary information, and
nonsolicitation of Company employees. Employee's signature below constitutes his
certification under penalty of perjury that, on or before the Effective Date, he
will return all documents and other items provided to Employee by the Company,
developed or obtained by Employee in connection with his employment with the
Company, or otherwise belonging to the Company.

11.    No Cooperation. Employee agrees that he will not knowingly encourage,
counsel, or assist any attorneys or their clients in the presentation or
prosecution of any disputes, differences, grievances, claims, charges, or
complaints by any third party against any of the Releasees, unless under a
subpoena or other court order to do so or as related directly to the ADEA waiver
in this Agreement. Employee agrees both to immediately notify the Company upon
receipt of any such subpoena or court order, and to furnish, within three (3)
business days of its receipt, a copy of such subpoena or other court order. If
approached by anyone for counsel or assistance in the presentation or
prosecution of any disputes, differences, grievances, claims, charges, or
complaints against any of the Releasees, Employee shall state no more than that
he cannot provide counsel or assistance.

12.    Mutual Nondisparagement. Employee agrees to refrain from any
disparagement, defamation, libel, or slander of any of the Releasees, and agrees
to refrain from any tortious interference with the contracts and relationships
of any of the Releasees. The Company agrees to refrain from any disparagement,
defamation, libel, or slander of the Employee, and agrees to refrain from any
tortious interference with the contracts and relationships of the Employee.
Employee understands that the Company's obligations under this paragraph extend
only to the Company's executive officers and members of its Board of Directors.
Employee shall direct any inquiries by potential future employers to the
Company's

--------------------------------------------------------------------------------

Chairman of the Board. In response to such requests, the Company shall respond
in a matter to be mutually agreed upon by the Parties.

13.    No Admission of Liability. Employee understands and acknowledges that
this Agreement constitutes a compromise and settlement of any and all actual or
potential disputed claims by Employee. No action taken by the Company hereto,
either previously or in connection with this Agreement, shall be deemed or
construed to be (a) an admission of the truth or falsity of any actual or
potential claims or (b) an acknowledgment or admission by the Company of any
fault or liability whatsoever to Employee or to any third party.

14.    Costs. The Parties shall each bear their own costs, attorneys' fees, and
other fees incurred in connection with the preparation of this Agreement.

15.    Tax Consequences. The Company makes no representations or warranties with
respect to the tax consequences of the payments and any other consideration
provided to Employee or made on his behalf under the terms of this Agreement.
Employee agrees and understands that he is responsible for payment, if any, of
local, state, and/or federal taxes on the payments and any other consideration
provided hereunder by the Company and any penalties or assessments thereon.
Employee further agrees to indemnify and hold the Company harmless from any
claims, demands, deficiencies, penalties, interest, assessments, executions,
judgments, or recoveries by any government agency against the Company for any
amounts claimed due on account of (a) Employee's failure to pay or delayed
payment of federal or state taxes, or (b) damages sustained by the Company by
reason of any such claims, including attorneys' fees and costs.

a.    Section 409A. The parties intend that upon Employee's Separation Date,
Employee had a “separation from service” within the meaning of Section 409A (as
defined below). The provisions of this Agreement 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 other 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. For
purposes of clarity, it is the intent of this Agreement that all payments of
severance benefits provided hereunder be exempt from the requirements of Section
409A to the maximum extent possible pursuant to the short-term deferral
exception described in Treasury Regulation Section 1.409A-1(b)(4) or otherwise.
It is the intent of the Parties that all payments of severance benefits that do
not qualify for an exemption from Section 409A pursuant to Treasury Regulation
Section 1.409A-1(b)(4) qualify for an alternate exemption from Section 409A or
meet the Section 409A requirements regarding time and form of payment. 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.

b.    For purposes of this Agreement, “Section 409A” means Section 409A of the
Internal Revenue Code of 1986, as amended, and the final regulations and any
guidance promulgated thereunder and any applicable state law equivalents (as
each may be amended or promulgated from time to time).

c.    The Parties agree to work together in good faith to consider amendments to
this Agreement and to take such reasonable actions that are necessary,
appropriate or desirable to avoid imposition of any additional tax or income
recognition prior to actual payment to Employee under Section 409A.

16.    Indemnifications. Employee agrees to indemnify and hold harmless the
Company from and against any and all loss, costs, damages, or expenses,
including, without limitation, attorneys' fees or expenses incurred by the
Company arising out of the breach of this Agreement by Employee, or from any
false representation made herein by Employee, or from any action or proceeding
that may be commenced, prosecuted, or threatened by Employee or for Employee's
benefit, upon Employee's initiative, direct or indirect, contrary to the
provisions of this Agreement. Employee further agrees that in any such action or
proceeding, this Agreement may be pled by the Company as a complete defense, or
may be asserted by way of counterclaim or cross-claim.

The Company agrees to indemnify and hold harmless the Employee from and against
any and all loss, costs, damages, or expenses, including, without limitation,
attorneys' fees or expenses incurred by the Employee arising out of the breach
of this Agreement by the Company, or from any false representation made herein
by the Company. The Company further agrees that in any such action or
proceeding, this Agreement may be pled by the Employee as a complete defense, or
may be asserted by way of counterclaim or cross-claim.

17.    Resignation as Director and Officer. Employee hereby confirms that he
resigned as a member of the Company's Board of Directors effective on the
Separation Date. Employee acknowledges and agrees that he shall resign as

--------------------------------------------------------------------------------

director and officer, as the case may be, from any of the Company's subsidiaries
and branches where he serves as director and/or officer.

18.    Authority. The Company represents and warrants that the undersigned has
the authority to act on behalf of the Company and to bind the Company and all
who may claim through it to the terms and conditions of this Agreement. Employee
represents and warrants that he has the capacity to act on his own behalf and on
behalf of all who might claim through him to bind them to the terms and
conditions of this Agreement. Each Party warrants and represents that there are
no liens or claims of lien or assignments in law or equity or otherwise of or
against any of the claims or causes of action released herein.

19.    No Representations. Employee represents that he has had an opportunity to
consult with an attorney, and has carefully read and understands the scope and
effect of the provisions of this Agreement. Employee has not relied upon any
representations or statements made by the Company that are not specifically set
forth in this Agreement.

20.    Severability. In the event that any provision or any portion of any
provision hereof or any surviving agreement made a part hereof becomes or is
declared by a court of competent jurisdiction or arbitrator to be illegal,
unenforceable, or void, this Agreement shall continue in full force and effect
without said provision or portion of provision.

21.     Attorneys ' Fees . Except with regard to a legal action challenging or
seeking a determination in good faith of the validity of the waiver herein under
the ADEA, in the event that either Party brings an action to enforce or effect
its rights under this Agreement, the prevailing Party shall be entitled to
recover its costs and expenses, including the costs of mediation, arbitration,
litigation, court fees, and reasonable attorneys' fees incurred in connection
with such an action.

22.    Entire Agreement. With the exception of the Confidentiality Agreement,
Severance Agreement and the Stock Option Agreements, this Agreement represents
the entire agreement and understanding between the Company and Employee
concerning the subject matter of this Agreement and Employee's employment with
and separation from the Company and the events leading thereto and associated
therewith, and supersedes and replaces any and all prior agreements and
understandings concerning the subject matter of this Agreement and Employee's
relationship with the Company. Notwithstanding the foregoing, the
indemnification and other provisions of the Indemnity Agreement made as of June
8, 2010, between the Parties shall continue in force to the extent set forth
therein.

23.    No Oral Modification. This Agreement may only be amended in a writing
signed by
Employee and the Chairman of the Board of the Company.

24.    Governing Law. This Agreement shall be governed by the laws of the State
of California, without regard for choice-of-law provisions. Employee consents to
personal and exclusive jurisdiction and venue in the State of California.

25.    ARBITRATION. THE PARTIES AGREE THAT ANY AND ALL DISPUTES ARISING OUT OF
THE TERMS OF THIS AGREEMENT AND THE SUPPLEMENTAL RELEASE, THEIR INTERPRETATION,
AND ANY OF THE MATTERS HEREIN RELEASED, SHALL BE SUBJECT TO ARBITRATION IN
ALAMEDA COUNTY, CALIFORNIA BEFORE JUDICIAL ARBITRATION & MEDIATION SERVICES
(“JAMS”), PURSUANT TO ITS EMPLOYMENT ARBITRATION RULES & PROCEDURES (“JAMS
RULES”). THE ARBITRATOR MAY GRANT INJUNCTIONS AND OTHER RELIEF IN SUCH DISPUTES.
THE ARBITRATOR SHALL ADMINISTER AND CONDUCT ANY ARBITRATION IN ACCORDANCE WITH
CALIFORNIA LAW, INCLUDING THE CALIFORNIA CODE OF CIVIL PROCEDURE, AND THE
ARBITRATOR SHALL APPLY SUBSTANTIVE AND PROCEDURAL CALIFORNIA LAW TO ANY DISPUTE
OR CLAIM, WITHOUT REFERENCE TO ANY CONFLICT-OF-LAW PROVISIONS OF ANY
JURISDICTION. TO THE EXTENT THAT THE JAMS RULES CONFLICT WITH CALIFORNIA LAW,
CALIFORNIA LAW SHALL TAKE PRECEDENCE. THE DECISION OF THE ARBITRATOR SHALL BE
FINAL, CONCLUSIVE, AND BINDING ON THE PARTIES TO THE ARBITRATION. THE PARTIES
AGREE THAT THE PREVAILING PARTY IN ANY ARBITRATION SHALL BE ENTITLED TO
INJUNCTIVE RELIEF IN ANY COURT OF COMPETENT JURISDICTION TO ENFORCE THE
ARBITRATION AWARD. THE PARTIES TO THE ARBITRATION SHALL EACH PAY AN EQUAL SHARE
OF THE COSTS AND EXPENSES OF SUCH ARBITRATION, AND EACH PARTY SHALL SEPARATELY
PAY FOR ITS RESPECTIVE COUNSEL FEES AND EXPENSES; PROVIDED, HOWEVER, THAT THE
ARBITRATOR SHALL AWARD ATTORNEYS' FEES AND COSTS TO THE PREVAILING PARTY, EXCEPT
AS PROHIBITED BY LAW. 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.
NOTWITHSTANDING THE FOREGOING, THIS SECTION 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 THIS AGREEMENT AND THE AGREEMENTS INCORPORATED HEREIN BY REFERENCE.
SHOULD ANY PART OF THE ARBITRATION AGREEMENT CONTAINED IN THIS PARAGRAPH
CONFLICT WITH ANY OTHER ARBITRATION AGREEMENT BETWEEN THE PARTIES, THE PARTIES
AGREE THAT THIS ARBITRATION AGREEMENT SHALL GOVERN.

facsimile, and each counterpart and facsimile shall have the same force and
effect as an original and shall constitute an effective, binding agreement on
the part of each of the undersigned.

27.    Effective Date. Employee understands that this Agreement shall be null
and void if not executed by him within twenty-one (21) days. The Employee has
seven (7) days after signing this Agreement to revoke it. This Agreement will
become effective on the eighth (8th) day after Employee signed this Agreement,
so long as it has been signed by the Parties and has not been revoked by the
Employee before that date (the “Effective Date”). Notwithstanding Section 3(b)
of the Severance Agreement, the Employee acknowledges that the delay in entering
into this Release Agreement after the Separation Date may result in the
Effective Date falling after the sixtieth day following the Separation Date, and
agrees that the Effective Date will in any event be the eighth (8th) day after
Employee signs this Release Agreement.

28.    Voluntary Execution of Agreement. Employee understands and agrees that he
