You agree that, except as provided in this Transition Agreement, you are not and will not be entitled to any severance or acceleration benefits, including, without limitation, under the Option Agreements and the Employment Agreement, as a result of your resignation.

10. Section 409A. It is intended that the terms of this Transition Agreement comply with Section 409A of the Internal Revenue Code of 1986, as amended, the final regulations and any guidance promulgated thereunder (collectively, “Section 409A”) or an exemption therefrom, and the terms of this Transition Agreement will be interpreted accordingly; provided, however, that the Company, its affiliates, and their respective employees, officers, directors, agents and representatives (including, without limitation, legal counsel) will not have any liability to you with respect to any taxes, penalties, interest or other costs or expenses you or any related party may incur with respect to or as a result of Section 409A or for damages for failing to comply with Section 409A. Notwithstanding any provision to the contrary in this Transition Agreement, with respect to any amounts under this Transition Agreement that are determined to be deferred compensation for purposes of Section 409A and payable as a result of your termination of employment, you shall not be deemed to have terminated employment unless and until you have experienced a “separation from service” (as that term is used in Section 409A). Payments pursuant to this Transition Agreement are intended to constitute separate payments for purposes of Section 409A. To the extent you are a “specified employee,” as defined in Section 409A and any elections made by the Company in accordance therewith, notwithstanding the timing of payment provided in any other section of this Transition Agreement, to the extent required by Section 409A, no payment, distribution or benefit under this Transition Agreement that constitutes a distribution of deferred compensation (within the meaning of Section 409A) upon “separation from service” (as that term is used in Section 409A), after taking into account all available exemptions, that would otherwise be payable, distributable or settled during the six (6) month period after separation from service, will be made during such six (6) month period, and any such payment, distribution or benefit will instead be paid on the first business day after such six (6) month period, provided, however, that if you die following the date of termination and prior to the payment, distribution, settlement or provision of any payments, distributions or benefits delayed on account of Section 409A, such payments, distributions or benefits shall be paid or provided to the personal representative of your estate within thirty (30) days after the date of your death. To the extent that the payment of any amount hereunder constitutes “nonqualified deferred compensation” for purposes of Section 409A, if the applicable sixty (60) day period described in either Section 6 or Section 8 above spans calendar years, the payments will be made in the second calendar year. Any reimbursements or in-kind benefits provided to or for your benefit that constitute deferred compensation for purposes of Section 409A shall be provided in a manner that complies with Section 409A. Accordingly, (a) all such reimbursements will be made not later than the last day of the calendar year after the calendar year in which the expenses

were incurred, (b) any right to such reimbursements or in-kind benefits will not be subject to liquidation or exchange for another benefit, and (c) the amount of the expenses eligible for reimbursement, or the amount of any in-kind benefit provided, during any taxable year will not affect the amount of expenses eligible for reimbursement, or the in-kind benefits provided, in any other taxable year.

In exchange for the agreements contained in this Transition Agreement, which you acknowledge exceeds any amounts to which you otherwise may be entitled under the Company’s policies and practices or applicable law, you on behalf of yourself and your heirs, executors, representatives and assigns, hereby fully acquits, releases, waives and discharges from and agree that you have not and will not file, cause to be filed or pursue against, the Company, its affiliates, related parties, parent or subsidiary companies, and its and their present and former directors, officers, employees, agents, committee members, attorneys and representatives, and each of the foregoing’s successors and assigns (including, without limitation, Parent) (the “Released Parties”) all claims obligations, liabilities, complaints, causes of action, charges, debts, and demands of any kind, known and unknown, in law or in equity, asserted or unasserted (“Claims”) which you may now have or have ever had against any of them, or arising out of your relationship with any of them, including all claims for compensation and bonuses, attorneys’ fees, and all claims arising from your employment with the Company or the termination of your employment, whether based on contract, tort, statute, local ordinance, rule, regulation or any comparable law in any jurisdiction (“Released Claims”).

You understand that you are not waiving any right or Claim that cannot be waived as a matter of law, such as workers’ compensation Claims, Claims for indemnification under California Labor Code Section 2802, Claims for unemployment insurance benefits, your right to vested equity or other vested benefits, or as otherwise set forth in this Transition Agreement. YOU UNDERSTAND AND AGREE THAT THIS TRANSITION AGREEMENT CONTAINS A GENERAL RELEASE OF ALL CLAIMS.

You further agree that any change to this Transition Agreement, whether material or immaterial, will not restart the twenty-one (21) day period for you to consider the terms of this Transition Agreement.

13. Section 1542. You further agree that because this release specifically covers known and unknown claims, you waive your rights under Section 1542 of the California Civil Code, or under any comparable law of any other jurisdiction. Section 1542 states:

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

You intend for this release to be enforced to the fullest extent permitted by law.

This General Release does not release any rights you may have pursuant to this Transition Agreement or Independent Contractor Services Agreement.

14. Confidentiality. You further agree to maintain this Transition Agreement and its contents in the strictest confidence and agree that you will not disclose the terms of this Transition Agreement to any third party (other than your legal and financial advisors) without the prior written consent of the Company, unless otherwise required by law. If you are obligated under law to disclose the contents of this Transition Agreement, you agree, to the extent possible, to provide the Company at least five (5) days prior written notice of such obligation. You also agree that during your continued services with the Company and for five (5) years thereafter, you will not make or publish, either orally or in writing, any disparaging statement regarding any Released Parties. The Company agrees that during such period it shall instruct its executive officers and directors to refrain from making or publishing, either orally or in writing, any disparaging statements concerning you to any third parties; provided, however, that the Company shall be permitted to (a) respond truthfully to reference requests from your potential future employers, and (b) disclose the reasons for your departure to current and prospective equityholders, officers, directors, investors, financing sources, underwriters, acquirors, strategic partners or any representative or affiliate or the foregoing, and both parties may make disclosures necessary or advisable to comply with applicable law, rule, regulation, securities exchange requirement or court order.

This includes being available to provide information or explain documents as requested by the Company and its counsel as well as disclosing to the Company and its counsel any facts you know which might be relevant and cooperating fully so as to enable the Company and its counsel to present any claim or defense which it may have relating to such matters. In addition, you agree not to 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 the Company, unless under subpoena or other court or administrative order or legal process to do so.

16. Right to Disclose. Notwithstanding any other provision of this Transition Agreement to the contrary, you have the right to (a) disclose in confidence trade secrets to federal, state, and local government officials, or to an attorney, for the sole purpose of reporting or investigating a suspected violation of the law or (b) disclose trade secrets in a document filed in a lawsuit or other proceeding so long as that filing is made under seal and protected from public disclosure. Nothing in this Transition Agreement is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by 18 U.S.C. § 1833(b).

17. Proprietary Information. You agree that, notwithstanding any other provision of this Transition Agreement to the contrary and without limiting in any manner the Proprietary Information Agreement, as a precondition of your eligibility for and receipt of the Consideration, you shall return to the Company all Company documents (and all copies thereof) and other Company property that you have had in your possession at any time, including, but not limited to, CD’s, electronic files and/or storage devices, presentations; Company files, notes, drawings, records, business plans and forecasts, financial information, specifications, computer-recorded information, tangible property (including, but not limited to, computers, phones, credit cards, entry cards, identification badges and building and desk keys); and, any materials of

By agreeing to arbitrate, the parties are waiving their respective rights to a jury trial with regard to any of the above-referenced claims.

19. Entire Agreement. This Transition Agreement constitutes the entire agreement and understanding between you and the Company concerning its subject matter, replaces and supersedes any and all prior agreements and understandings between us (other than the Proprietary Information Agreement, which shall remain in full force and effect), and may only be amended in writing signed by you and an authorized representative of the Company, and that, except for the Proprietary Information Agreement and the Independent Contractor Services Agreement, and except as otherwise expressly provided in this Transition Agreement, this Transition Agreement renders null and void any and all prior or contemporaneous representations, warranties or agreements between you and the Company or any affiliate of the Company. It is agreed that this Transition Agreement shall be governed by the laws of the State of California. If any provision of this Transition Agreement or the application thereof to any person, place, or circumstance shall be held by a court of competent jurisdiction or arbitrator to be invalid, unenforceable, or void, the remainder of this Transition Agreement and such provision as applied to other person, places, and circumstances shall remain in full force and effect.

In accordance with the Transition Agreement, and in exchange for the Termination Consideration, which you acknowledge exceeds any amounts to which you otherwise may be entitled under the Company’s policies and practices or applicable law, you on behalf of yourself and your heirs, executors, representatives and assigns, hereby fully acquits, releases, waives and discharges from and agree that you have not and will not file, cause to be filed or pursue against, the Company, its affiliates, related, parent or subsidiary companies, and its and their present and former directors, officers, employees, agents, committee members, attorneys and representatives, and each of the foregoing’s successors and assigns (including, without limitation, Parent) (the “Released Parties”) all claims obligations, liabilities, complaints, causes of action, charges, debts, and demands of any kind, known and unknown, in law or in equity, asserted or unasserted (“Claims”) which you may now have or have ever had against any of them, or arising out of your relationship with any of them, including all claims for compensation and bonuses, attorneys’ fees, and all claims arising from your employment with the Company or the termination of your employment, whether based on contract, tort, statute, local ordinance, rule, regulation or any comparable law in any jurisdiction (“Released Claims”).

Released Claims include, but are not limited to:

(iii) all Claims for breach of contract, breach of quasi-contract, promissory estoppel, detrimental reliance, and breach of the implied covenant of good faith and fair dealing;

(v) all federal, state, and local statutory Claims, including Claims for discrimination, harassment, retaliation, attorneys’ fees, medical expenses, experts’ fees, costs and disbursements; and

(vi) any other Claims of any kind whatsoever, from the beginning of time until the date you sign this General Release Agreement, in each case whether based on contract, tort, statute, local ordinance, rule, regulation or any comparable law, public policy or common law in any jurisdiction.

Act, 29 U.S.C. § 2601 et seq.; the Employee Retirement Income Security Act of 1974, 29 U.S.C. § 1001 et seq.; the federal Worker Adjustment Retraining Notification Act, 29 U.S.C. § 2102 et seq., the California WARN Act, California Labor Code § 1400 et seq., the California Fair Employment and Housing Act, Cal. Gov. Code §12900 et seq., the California Labor Code, and the orders of the California Industrial Welfare Commission. The parties intend for this release to be enforced to the fullest extent permitted by law. You understand that you are not waiving any right or Claim that cannot be waived as a matter of law, such as workers’ compensation Claims, Claims for indemnification under California Labor Code Section 2802, Claims for unemployment insurance benefits, your right to vested equity or other vested benefits, or as otherwise set forth in this General Release Agreement. YOU UNDERSTAND AND AGREE THAT THIS GENERAL RELEASE AGREEMENT CONTAINS A GENERAL RELEASE OF ALL CLAIMS.

You further agree that because this release specifically covers known and unknown claims, you waive your rights under Section 1542 of the California Civil Code, or under any comparable law of any other jurisdiction. Section 1542 states:

You intend for this release to be enforced to the fullest extent permitted by law. Notwithstanding the foregoing, you acknowledge and agree that you are not waiving or being required to waive any right that cannot be waived as a matter of law, including the right to file a charge, report an alleged violation of law or participate in an investigation by a governmental administrative agency, including your ability to file a charge or complaint with the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission or any other federal, state or local government agency or commission (“Government Agencies”). You further understand that this General Release Agreement does not limit your ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company; provided, however, that you hereby disclaim and waive any right to share or participate in any monetary award resulting from the prosecution of such charge, report or investigation, except that you may receive and fully retain a monetary award from a government-administered whistleblower award program for providing information directly to a government agency. This General Release does not release any rights you may have pursuant to the Transition Agreement or Independent Contractor Services Agreement.

You further specifically unconditionally release and forever discharge the Released Parties from any and all Claims that you may have as of the date you sign this General Release Agreement arising under the ADEA. By signing this General Release Agreement, you acknowledge and confirm that: (i) you have been advised by the Company to consult with an attorney of your choice before signing this General Release Agreement; (ii) you were given no fewer than [twenty-one (21) or forty-five (45)] days to consider the terms of this General Release Agreement, although you may sign it sooner if desired; (iii) you are providing this release in exchange for consideration in addition to that which you are already entitled; (iv) you have seven (7) days from the date of signing this General Release Agreement to revoke this General Release Agreement by providing the Company with a written notice of revocation to the current [Chairman of the Board of Directors of the Company] at the Company’s principal executive office located at [LOCATION], before the end of such seven-day period (“Revocation Period”); (v) this General Release Agreement will not become effective, and you will not be entitled to any Termination Consideration, until the Revocation Period passes without you revoking this General Release Agreement; (vi) the release contained in this

paragraph does not apply to rights and claims that may arise after the date on which you sign this General Release Agreement, and (vii) you knowingly and voluntarily accept the terms of this General Release Agreement. You further agree that any change to this General Release Agreement, whether material or immaterial, will not restart the [twenty-one (21) or forty-five (45)] day period for you to consider the terms of this General Release Agreement.

You affirm that you have not initiated, filed or caused to be filed and agree not to initiate, file or cause to be filed any Released Claims against any of the Released Parties. You further agree not to encourage any person, including any current or former Company employee, to file any kind of claim whatsoever against the Released Parties, or any of them, and not to solicit, assist, support or in any way cooperate in the initiation or prosecution of any action or proceeding brought against the Released Parties, or any of them, by a third party, except if compelled to do so by legal process which includes when compelled by court order, subpoena or written request by an administrative agency or the legislature to testify regarding alleged criminal conduct or alleged sexual harassment.

Notwithstanding anything to the contrary in this General Release Agreement, nothing in this General Release Agreement shall prohibit or interfere with you exercising protected rights to file a charge with or report to any Governmental Agency. You do not need the Company’s advance permission to file any such charge or report or to participate in any such investigation. You do, however, waive any right to receive any monetary award or benefit resulting from such a charge, report, or investigation related to any Released Claims, except that you may receive and fully retain a monetary award from a government-administered whistleblower award program. You further acknowledge and agree that this General Release Agreement shall not be construed as a waiver of any rights that are not subject to waiver by private agreement or otherwise cannot be waived as a matter of law.

You represent and warrant that you have returned to the Company—and have not retained any copies of—all Company property, including, without limitation, all documents and data in whatever form maintained, confidential information, computer hardware or software, files, papers, memoranda, correspondence, client lists, employee information, financial records and information, credit cards, keys, access cards, tape recordings, pictures and any other items of any nature which were or are the property of the Company. You understand that you will not be eligible for any Termination Consideration, until you return all Company property.

You agree to reasonably cooperate with the Company in any pending or future litigation and/or administrative investigation in which the Company is a party and/or is the subject of an administrative investigation where you have relevant knowledge or information.

You agree that the Transition Agreement and this General Release Agreement contain all of the agreements and understandings between you and the Company with respect to their subject matter, and may not be contradicted by evidence of any prior or contemporaneous agreement; provided, however, that, the Proprietary Information Agreement shall not be modified in any way by this General Release Agreement and shall continue in full force and effect in accordance with its terms. This General Release Agreement shall be governed by the laws of the State of California. If any provision of this General Release Agreement or its application to any person, place, or circumstance is held by a court of competent jurisdiction to be invalid, unenforceable, or void, the remainder of this General Release Agreement and such provision as applied to other person, places, and circumstances will remain in full force and effect. Nothing in this General Release Agreement shall be construed as an admission by any party of any wrongdoing, violation of the Company’s policies or procedures, or violations of any federal, state or local law.

Finally, by your signature below, you acknowledge each of the following: (a) you have read this General Release Agreement or have been afforded every opportunity to do so; (b) you are fully aware of this General

Release Agreement’s contents and legal effect; (c) you have reviewed, or have had the opportunity to review, this General Release Agreement with legal counsel of your choosing; and (d) you have chosen to enter into this General Release Agreement freely, without coercion and based upon your own judgment and not in reliance upon any promises made by the Company other than those contained in this General Release Agreement.
