NOW THEREFORE, for good and valuable consideration, including the mutual promises and covenants made herein, the Company and Executive hereby agree as follows:

1.    Termination. Executive’s employment with the Company will terminate on the Termination Date. The Termination Date will be the termination date of Executive’s employment with the Company and any of its affiliates for all purposes, including active participation in and coverage under all benefit plans and programs sponsored by or through the Company and its affiliates, except as provided in this Agreement. Executive hereby confirms his resignation from all positions he holds with the Company and any of its affiliates, including his position as Chief Executive Officer of the Company, effective as of the Termination Date. In addition, Executive hereby irrevocably resigns as a member of the board of directors of the Company (the “Board”), effective December 31, 2022. In the event Executive’s service as a member of the Board does not terminate effective December 31, 2022, Executive shall not be eligible for any of the Termination Benefits hereunder, all of which shall be immediately forfeited. Executive shall execute any additional documentation necessary to effectuate the foregoing.

    (a)    Accrued Compensation. On the first regularly scheduled payroll date following the Termination Date (or such earlier time required by applicable law), the Company will pay Executive all accrued but unpaid wages, including any accrued, unused vacation or paid time off, through the Termination Date. Executive shall receive any other benefits due to Executive under any Company-provided plans, policies, and arrangements in accordance with such plans, policies or arrangement. Executive acknowledges and represents that, other than the consideration to be paid in accordance with this Section 2 or Section 3 below, the Company has paid or provided all salary, wages, bonuses, accrued vacation/paid time off, premiums, leaves, housing allowances, relocation costs, interest, severance, outplacement costs, fees, reimbursable expenses, commissions, draws, stock, stock options or other equity awards (including restricted stock unit awards), vesting, and any and all other benefits and compensation due to Executive and that no other reimbursements or compensation are owed to Executive, including

under the Company’s Amended and Restated Severance Plan (the “Severance Plan”) and the Offer Letter.

    (b)    Expenses. The Company will reimburse Executive for any and all reasonable and necessary business expenses incurred by Executive in connection with the performance of his job duties prior to the Termination Date in accordance with the Company’s policies, which expenses shall be submitted to the Company with supporting receipts and/or documentation no later than thirty (30) days after the Termination Date.

    (c)     Benefits. Subject to Section 3 below, and except as otherwise required by applicable law, Executive’s entitlement to health benefits from the Company, and eligibility to participate in the Company’s health benefit plans, shall cease on the last day of the calendar month during which the Termination Date occurs, except to the extent Executive elects to and is eligible to receive continued healthcare coverage pursuant to the provisions of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), for himself and any covered dependents. Executive’s entitlement to other benefits from the Company, and eligibility to participate in the Company’s other benefit plans and programs, shall cease on the Termination Date.

    (d)    Director Compensation. Notwithstanding anything to the contrary in the Company’s Director Compensation and Stock Ownership Policy, you will not be eligible for any compensation thereunder for the period commencing on the Termination Date and December 31, 2022.

3.    Termination Benefits. In consideration for Executive’s agreement to be bound by the terms of this Agreement, including but not limited to the release of claims in Section 4, but subject to Executive’s continued compliance with the terms of this Agreement, including Section 9, and Executive’s resignation as a member of the Board effective December 31, 2022 in accordance with Section 1, the Company agrees to provide Executive with the following termination benefits (the “Termination Benefits”):

    (a)    Severance. Subject to Sections 15(b) and (c), Executive shall be eligible to receive continued payment of Executive’s base salary at the rate in effect on the Termination Date ($730,455.12 per year) for a period of eighteen (18) months following the Termination Date, in accordance with the Company’s then-current payroll policies and practices. For the avoidance of doubt, Executive will not be entitled to any bonus, or pro-rated portion thereof, for fiscal year 2022.

    (b)    Equity Vesting. Notwithstanding any language to the contrary set forth in any award agreements issued to Executive under Company’s 2002 Stock Incentive Plan, upon the later of (i) the Effective Date or (ii) January 1, 2023, for awards the vesting of which is solely time-based and not subject to the satisfaction of a performance condition, the unvested portion of any such unvested stock option or restricted stock unit granted to Executive shall vest. As of the later of (i) the Effective Date or (ii) January 1, 2023, all equity awards that are subject to the satisfaction of a performance condition (including, without limitation, all performance stock units granted to Executive), shall vest at the “target” levels and any remaining portion of such award not eligible to vest pursuant to this Section 3(b) shall terminate immediately upon the Termination Date. Executive’s equity awards as of the Termination Date are set forth on Exhibit B. For the avoidance of doubt, the foregoing acceleration pursuant to this Section 3(b) shall only apply to outstanding awards issued by the Company and shall not apply to any awards issued to Executive by OmniAb, Inc. (including any such awards issued to Executive by OmniAb, Inc. upon the conversion or adjustment of Company equity awards pursuant to that certain Amended and Restated Employee Matters Agreement (the “Employee Matters Agreement”), by and among the Company, OmniAb, Inc., Avista Public Acquisition Corp. II and Orwell Merger Sub Inc., dated as of August 18, 2022, or that certain Agreement and Plan of Merger, by and among the Company, OmniAb, Inc., Avista Public Acquisition Corp. II and Orwell Merger Sub Inc., a Delaware corporation, dated March 23, 2022) (together, the “OmniAb Awards”), which OmniAb Awards are not governed by the terms of this Agreement and shall instead be governed by the terms and conditions of the equity award agreements and the equity plan under which such equity awards were granted and the Employee Matters Agreement (including any accelerated vesting thereof as a result of Executive’s termination of employment with the Company and the accelerated vesting of his Company equity awards pursuant to this Section 3(b) in accordance with the equity award agreements and the equity plan under which such

equity awards were granted and the Employee Matters Agreement). With respect to any tax withholding obligation arising in connection with the vesting and settlement of the restricted stock units or performance stock units held by Executive, the vesting of which will accelerate pursuant to this Section 3(b), such tax withholding obligation shall be automatically satisfied by means of the surrender or withholding of a net number of vested shares of Company common stock subject to such awards having a then current fair market value not exceeding the amount necessary to satisfy the tax withholding obligation of the Company based on the minimum applicable statutory withholding rates for federal, state and local income tax and payroll tax purposes, in accordance with the terms of the Company’s 2002 Stock Incentive Plan pursuant to which such equity awards were granted. Except as provided in Section 3(c), Executive’s vested Company equity awards shall be governed by the terms and conditions of the equity award agreements and the Company’s 2002 Stock Incentive Plan under which such equity awards were granted.

    (c)    Extension of Post-Termination Exercise Period. Notwithstanding anything to the contrary contained in the Company’s 2002 Stock Incentive Plan and the equity award agreements under which Executive’s outstanding stock options were granted:

        (i)    Subject to the terms and conditions contained in, and Executive’s continued compliance with, this Section 3(c), the period of time during which Executive may exercise his vested stock options following the Termination Date (after giving effect to the acceleration pursuant to Section 3(b) above) shall be extended to the earliest of (A) the second anniversary of the Termination Date or (B) the original ten-year expiration date of such options (the “Exercise Period Extension”).

            (ii)    It shall be a condition to the Exercise Period Extension that Executive not sell, pledge, assign, hypothecate, transfer, or otherwise dispose of (collectively, “Transfer”) on any single trading day occurring during the period commencing on the Termination Date and ending on the second anniversary of the Termination Date, shares of the Company’s common stock (including shares issuable upon vesting, settlement or exercise of stock options, restricted stock units or performance stock units) in an amount that is in excess of five percent (5%) of the average daily trading volume of the Company’s common stock for the preceding calendar week, other than Permitted Transfers. For purposes of this Agreement, a “Permitted Transfer” will include (A) the Transfer of any or all of the shares during Executive’s lifetime or upon Executive’s death by will or intestacy to Executive’s Immediate Family or a trust for the benefit of Executive’s Immediate Family (provided that such Immediate Family or trust agrees to be bound by the restrictions in this Section 3(c)), (B) any Transfer upon the occurrence of, and in connection with, a change in control of the Company, (C) any Transfer approved in writing by the Board, (D) any Transfer pursuant to the written trading plan adopted by the Executive on September 22, 2022, in accordance with Rule 10b5-1, or (E) any Transfer to the Company in connection with tax withholding by the Company as described in Section 3(b) above. As used herein, “Immediate Family” shall mean Executive’s spouse, lineal descendant or antecedent, father, mother, brother or sister or stepchild (whether or not adopted).

            (iii)    It shall be a further condition to the Exercise Period Extension that Executive not Transfer any of the shares of the Company’s common stock currently held by Executive in a brokerage account at Morgan Stanley or E*Trade (or any shares issuable upon vesting, settlement or exercise of stock options or restricted stock units after the Termination Date) to another account without the prior written consent of the Company. Executive acknowledges and agrees that the Company may place restrictions on any such brokerage account to ensure Executive’s compliance with the restrictions in this Section 3(c).

        (iv)    In the event Executive breaches this Section 3(c) or Section 9, Executive’s ability to exercise his vested stock options shall immediately cease and all of Executive’s vested stock options shall cease to be exercisable on the date of such breach and shall be forfeited.

        (v)    Executive acknowledges that, as a result of the foregoing Exercise Period Extension, any outstanding stock option classified as an “incentive stock option” under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), may be immediately reclassified as a non-qualified stock option, and that Executive, and not the Company, shall be solely responsible for any tax

consequences relating to such reclassification (including as a result of any loss of incentive stock option treatment with respect to any outstanding stock options).

        (vi)    For the avoidance of doubt, the Exercise Period Extension shall only apply to outstanding awards issued by the Company and shall not apply to any OmniAb Awards, which OmniAb Awards are not governed by this Agreement and shall instead be governed by the terms and conditions of the equity award agreements and the equity plan under which such equity awards were granted and the Employee Matters Agreement.

    (d)    Continuation Coverage. If Executive elects continuation coverage pursuant to COBRA within the time period prescribed pursuant to COBRA for Executive and Executive’s eligible dependents, then the Company will reimburse Executive for the COBRA premiums for such coverage (at the coverage levels in effect immediately prior to Executive’s termination) until the earlier of (i) a period of eighteen (18) months from the Termination Date or (ii) the date upon which Executive becomes covered under similar plans of a subsequent employer. The reimbursements will be made by the Company to Executive consistent with the Company’s normal expense reimbursement policy. Notwithstanding the first sentence of this Section 3(d), if the Company determines in its sole discretion that it cannot provide the foregoing benefit without potentially violating, or being subject to an excise tax under, applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company will in lieu thereof provide to Executive a taxable monthly payment, payable on the last day of a given month, in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue Executive’s group health coverage in effect on the termination of employment date (which amount will be based on the premium for the first month of COBRA coverage), which payments will be made regardless of whether Executive elects COBRA continuation coverage and will commence on the month following Executive’s termination of employment and will end on the earlier of (x) the date upon which Executive obtains other employment or (y) the date the Company has paid an amount equal to eighteen (18) such payments. For the avoidance of doubt, the taxable payments in lieu of COBRA reimbursements may be used for any purpose, including, but not limited to continuation coverage under COBRA, and will be subject to all applicable tax withholdings.

4.    Release of Claims. Executive agrees that the consideration to be paid in accordance with Section 3 of this Agreement represents settlement in full of all outstanding obligations owed to Executive by the Company and its current and former officers, directors, employees, agents, investors, attorneys, stockholders, administrators, affiliates, benefit plans, plan administrators, insurers, trustees, divisions, and subsidiaries, and predecessor and successor corporations and assigns (collectively, the “Releasees”). Executive, on Executive’s own behalf and on behalf of Executive’s 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 Executive may possess against any of the Releasees arising from any omissions, acts, facts, or damages that have occurred up until and including the date of Executive’s execution of this Agreement, including, without limitation the following:

5.    Acknowledgment of Waiver of Claims under ADEA. Executive acknowledges that Executive is waiving and releasing any rights Executive may have under the Age Discrimination in Employment Act of 1967 (“ADEA”) and that this waiver and release is knowing and voluntary. Executive agrees that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the date on which Executive executes this Agreement. Executive acknowledges that the consideration given for this waiver and release Agreement is in addition to anything of value to which Executive was already entitled. Executive further acknowledges that Executive is hereby advised by this writing that (a) Executive should consult with an attorney prior to executing this Agreement; (b) Executive has at least twenty-one (21) days within which to consider this Agreement; (c) Executive has seven (7) days following the execution of this Agreement by the Parties to revoke the Agreement; (d) this Agreement will not be effective until the revocation period has expired; and (e) nothing in this Agreement prevents or precludes Executive 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 Executive signs this Agreement and delivers

it to the Company in less than the twenty-one (21)-day period identified above, Executive hereby acknowledges that Executive has freely and voluntarily chosen to waive the time period allotted for considering this Agreement. Executive acknowledges and understands that revocation must be accomplished by a written notification to the Chief Legal Officer of the Company that is received prior to the Effective Date.

6.    Unknown Claims. Executive acknowledges that Executive 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:

    Executive, being aware of California Civil Code Section 1542, agrees to expressly waive any rights Executive may have thereunder, as well as under any other statute or common law principles of similar effect.

7.    No Pending or Future Lawsuits. Executive represents that Executive has no lawsuits, claims, or actions pending in Executive’s name, or on behalf of any other person or entity, against the Company or any of the other Releasees. Executive also represents that Executive does not intend to bring any claims on Executive’s own behalf or on behalf of any other person or entity against the Company or any of the other Releasees. Executive confirms that Executive has no knowledge of any wrongdoing involving improper or false claims against a federal or state governmental agency, or any other wrongdoing that involves Executive or any other present or former Company employees, including violations of the federal and state securities laws.

8.    Sufficiency of Consideration. Executive hereby acknowledges and agrees that Executive has received good and sufficient consideration for every promise, duty, release, obligation, agreement and right contained in this Agreement and the Release contained in Section 4.

    (a)    Confidential Information. Executive reaffirms and agrees to observe and abide by the terms of the PIIA, specifically including the provisions therein regarding nondisclosure of the Company’s trade secrets and confidential and proprietary information, which agreement will continue in force and agrees that such obligations shall survive the Termination Date.

    (b)     Solicitation of Employees and Independent Contractors. For one (1) year following the Termination Date, Executive will not, either directly or through others, solicit or attempt to solicit any employee, independent contractor or consultant of the Company to terminate his or her relationship with the Company in order to become an employee, consultant or independent contractor to or for any other person or entity, or otherwise encourage or solicit any employee of the Company to leave the Company for any reason or to devote less than all of any such employee’s efforts to the affairs of the Company.

    (c)    Return of Company Property; Passwords and Password-protected Documents. Executive confirms that Executive has returned to the Company in good working order all keys, files, records (and copies thereof), equipment (including, but not limited to, computer hardware, software and printers, wireless handheld devices, cellular phones and pagers), access or credit cards, Company identification, and any other Company-owned property in Executive’s possession or control, provided that Executive may retain his personal copies of (i) his compensation records, (ii) materials distributed to stockholders generally and (iii) any written agreement to which Executive is a party. Executive further confirms that Executive has cancelled all accounts for Executive’s benefit, if any, in the Company’s name, including, but not limited to, credit cards, telephone charge cards, cellular phone and/or pager

accounts and computer accounts; provided, however, that Executive shall be permitted to retain his Company-provided laptop until December 31, 2022 in order to coordinate the transition of his personal files and emails from such laptop, subject to Executive’s cooperation with the Company’s information technology department in such transition. The Company shall keep Executive’s Company email active through December 31, 2022, or such later date as mutually agreed with the Company; provided that Executive will immediately forward any work-related emails that he receives at his Company email address to the Chief Executive Officer of the Company. Executive also confirms that Executive has delivered all passwords in use by Executive at the time of Executive’s termination, a list of any documents that Executive created or of which Executive is otherwise aware that are password-protected, along with the password(s) necessary to access such password-protected documents.

    (d)    Nondisparagement. Subject to Section 11 of this Agreement, Executive agrees that Executive will not make any negative or disparaging statements or comments, either as fact or as opinion, about Company, its employees, officers, directors, shareholders, vendors, products or services, business, technologies, market position or performance. The Company agrees that it shall not, and shall cause its directors and executive officers not to, make any negative or disparaging statements or comments, either as fact or as opinion, about Executive. Nothing in this paragraph will prohibit Executive or the Company from providing truthful information in response to a subpoena or other legal process.     

    (e)    Reformation of Provisions. If it is determined by a court of competent jurisdiction in any state that any restriction in this Section 9 is excessive in duration or scope or is unreasonable or unenforceable under the laws of that state, it is the intention of the parties that such restriction may be modified or amended by the court to render it enforceable to the maximum extent permitted by the law of that state.

    (f)    Remedies. It is expressly agreed that the Company and its subsidiaries and affiliates will or would suffer irreparable injury if Executive were to breach any of the provisions of this Section 9 and that the Company and its subsidiaries and affiliates would by reason of any such breach be entitled to injunctive relief in a court of competent jurisdiction without the need to post a bond or other security and without the need to demonstrate special damages. The aforementioned injunctive relief is and shall be in addition to any other remedies that may be available to the Company and its subsidiaries and affiliates under this Agreement or otherwise. In addition to all other rights and remedies available to the Company under law or in equity, the Company shall be entitled to withhold all Termination Benefits from Executive in the event of his breach of this Section 9.

10.    No Cooperation. Subject to Section 11 of this Agreement, Executive agrees that Executive 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. Executive 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, Executive will state no more than that Executive cannot provide any such counsel or assistance.

11.    Protected Activities. Notwithstanding anything herein to the contrary, nothing in this Agreement or the PIIA shall (a) prohibit Executive from filing a charge 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 comparable federal agency, state agency or securities regulatory body (the “Government Agencies”); (b) prohibit Executive from reporting possible violations of law to an appropriate Government Agency in a confidential manner without notice to the Company as authorized in any whistleblower protection provisions of any federal or state law or regulation; (c) communicating directly with any governmental, law enforcement, regulatory or self-regulatory body; (d) limit Executive’s lawful opportunity to cooperate with or participate in any administrative proceeding or investigation that may be conducted by a Government Agency; (e) receive awards from a Government Agency as a result of reporting or cooperation; or (f) discussing or disclosing

information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that Executive has reason to believe is unlawful. With respect to any information disclosed pursuant to this protected activity exception that may constitute confidential or proprietary information, Executive agrees to take all reasonable precautions to prevent any unauthorized use or disclosure to any parties other than the relevant agency or authority. Except as prohibited by applicable law, rule, or regulation, the payments paid to pursuant to this Agreement will be the sole monetary relief available to Executive, and Executive will not be entitled to recover, and agrees to waive, any additional personal monetary relief that may be sought from or awarded against the Company in the future without regard to who filed or brought such claim. However, this Agreement does not waive Executive’s right to receive an award for original information from any Government Agency, including but not limited to any such award pursuant to Section 21F of the Securities Exchange Act of 1934. Further, Executive’s participation in an investigation or other legal matter may include a disclosure of trade secret information provided that it must comply with the restrictions in the Defend Trade Secrets Act of 2016 (“DTSA”). The DTSA provides that no individual will be held criminally or civilly liable under Federal or State trade secret law for the disclosure of a trade secret that: (i) is made in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and made solely for the purpose of reporting or investigating a suspected violation of law; or, (ii) is made in a complaint or other document if such filing is under seal so that it is not made public. Also, an individual who pursues a lawsuit for retaliation by an employer for reporting a suspected violation of the law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal, and does not disclose the trade secret, except as permitted by court order.

12.    No Admission of Liability. Executive understands and acknowledges that this Agreement constitutes a compromise and settlement of any and all actual or potential disputed claims by Executive. No action taken by the Company hereto, either previously or in connection with this Agreement, will 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 Executive or to any third party.

13. Costs. The Parties will each bear their own costs, attorneys’ fees and other fees incurred in connection with the preparation of this Agreement.

    (a)    Agreement to Arbitrate.  The Company and Executive hereby agree to resolve by final and binding arbitration any and all claims or controversies in any way arising out of, relating to or associated with Executive’s employment with the Company or any of its parents, affiliates, or subsidiaries, or the termination of such employment or any breach of this Agreement. This mutual agreement to arbitrate includes any claims that the Company may have against Executive, or that Executive may have against the Company or against any of its officers, directors, employees, agents, successors, or parent, subsidiary, or affiliated entities so long as such claim is related to Executive’s employment with the Company. The Company and Executive agree that arbitration, as provided for in this Agreement, shall be the exclusive forum for the resolution of any covered dispute between the Parties. The Company and Executive agree that their mutual agreement to arbitrate shall constitute sufficient consideration by each Party for the promises made in this Section 14.

    (b)    Scope of Agreement. The claims covered by this Section 14 include, but are not limited to, claims for breach of any contract or covenant, express or implied; claims for breach of any fiduciary duty or other duty owed to Executive by Company or to Company by Executive; tort claims; claims for wages or other compensation due; claims for discrimination or harassment, including but not limited to discrimination or harassment based on race, sex, pregnancy, religion, national origin, ancestry, age, marital status, physical disability, mental disability, medical condition, or sexual orientation; and claims for violation of any federal, state or other governmental constitution, statute, ordinance or regulation (as originally enacted and as amended), including but not limited to claims under Title VII of the Civil Rights Act of 1964 (“Title VII”), the Fair Labor Standards Act, the Employee Retirement Income Security Act, the Consolidated Omnibus Budget Reconciliation Act (“COBRA”), and the Family and Medical Leave Act .

    (c)    Procedure.  Executive’s request to arbitrate must be directed to the Board at the Company’s principal place of business. A request submitted by the Company shall be sent to the Executive at the Executive’s address as reflected on the Company’s personnel records. Any arbitration shall be conducted before a single arbitrator of JAMS under the Employment Arbitration Rules and Procedures (the “Rules”) of JAMS then in effect. Executive can obtain a copy of the Rules on the website of JAMS, which is www.jamsadr.com and a copy will be provided to Executive upon request. JAMS has previously maintained the Rules at this URL: http://www.jamsadr.com/rules-employment-arbitration. The arbitration will be conducted in San Diego, California, and Executive and the Company consent to jurisdiction in California and venue in San Diego, California. If Executive is making a claim, the Company will pay any arbitration filing fee in excess of the amount Executive would have been required to pay (if any) to file the claim in court, and the Company will pay all of the arbitrator’s fees and other arbitration expenses. If the Company is making a claim, the Company will pay all filing fees and all expenses of the arbitration, including the arbitrator’s fees. Each Party shall bear its, his, or her own costs of legal representation; provided, however, if any Party prevails on a claim entitling the prevailing Party to attorneys’ fees and/or costs, the arbitrator may award reasonable fees and/or costs to the prevailing Party in accordance with such claim. The arbitrator shall have the authority to order such discovery by way of deposition, interrogatory, document production, or otherwise, as the arbitrator considers necessary to a full and fair exploration of the issues in dispute, consistent with the expedited nature of arbitration. The arbitrator shall issue a written decision that reveals the essential findings and conclusions on which the decision is based, and the arbitrator’s decision shall be subject to such judicial review as is provided by law. The mutual agreement to arbitrate claims as set forth in this Section 14 is enforceable under and governed by the Federal Arbitration Act, 9 U.S.C. § 1 et seq. (the “FAA”), but if the FAA is held not to apply to this Agreement for any reason, this mutual agreement to arbitrate claims shall be enforced under the laws of the State of California.

    (d)    Administrative Relief.  This Section 14 does not limit Executive’s right to file an administrative charge with the National Labor Relations Board, the Equal Employment Opportunity Commission, or any state agency charged with enforcement of fair employment practice laws, but Executive agrees to arbitrate under this Agreement all rights to any form of recovery or relief, including monetary or other damages. This agreement also does not apply to or cover claims for workers’ compensation benefits or compensation, claims for unemployment compensation benefits, or claims based upon an employee pension or benefit plan the terms of which contain an arbitration or other non-judicial dispute resolution procedure, in which case the provisions of such plan shall apply.

    (e)    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 Section 14 of this Agreement and fully understands it, including that EXECUTIVE EXPLICITLY WAIVES THE RIGHT TO TRIAL BY JURY of any claim subject to arbitration. The parties agree that any claim asserted in arbitration may be made only on an individual basis, and the parties may not assert claims on a representative, class or other collective basis. 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.

15.    Section 409A.

    (a)    Notwithstanding anything to the contrary in this Agreement, no severance pay or benefits to be paid or provided to Executive, if any, pursuant to this Agreement that, when considered together with any other severance payments or separation benefits, are considered deferred compensation subject to and not exempt from Section 409A of the Code, and the final regulations and any guidance promulgated thereunder (“Section 409A”) (together, the “Deferred Payments”) will be paid or otherwise provided until Executive has a “separation from service” within the meaning of Section 409A. The Company and Executive acknowledge and agree that the Termination Date will be the date of Executive’s “separation from service” within the meaning of Section 409A.

    (b)    Any severance payments or benefits under this Agreement will be paid on, or, in the case of installments, will not commence until, the date that is sixty (60) days following the Termination Date, or, if later, such time as required by Section 15(c). Except as required by Section 15(c), any installment payments that would have been made to Executive during the period immediately following Executive’s separation from service but for the preceding sentence will be paid to Executive with the initial installment commencing with the date that is sixty (60) days following the Termination Date and the remaining payments will be made as provided in this Agreement. In any case where Executive’s separation from service and the last day of the period during which Executive may deliver this Agreement fall in two separate calendar years, any amount required to be paid to Executive that is conditioned on the effectiveness of the Release and is treated as a Deferred Payment shall be paid in the later calendar year.

    (c)    Notwithstanding anything to the contrary in this Agreement, if Executive is a “specified employee” within the meaning of Section 409A on the Termination Date, 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 before the six (6) month anniversary of the separation from service, then any payments delayed in accordance with this Section 15(c) 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 under Section 1.409A-2(b)(2) of the Treasury Regulations. The Company has determined that the severance payments payable to Executive pursuant to Section 3(a) are Deferred Payments subject to delay pursuant to this Section 15(c); accordingly, the foregoing delay shall apply to such payments.

    (d)    Any reimbursement of expenses or in-kind benefits payable under this Agreement shall be made in accordance with Treasury Regulation Section 1.409A-3(i)(1)(iv) and shall be paid on or before the last day of Executive’s taxable year following the taxable year in which Executive incurred the expenses. The amount of expenses reimbursed or in-kind benefits payable in one year shall not affect the amount eligible for reimbursement or in-kind benefits payable in any other taxable year of Executive’s, and Executive’s right to reimbursement for such amounts shall not be subject to liquidation or exchange for any other benefit.

    (e)    The foregoing provisions are intended to comply with 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 herein will be interpreted to 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 before actual payment to Executive under Section 409A. Notwithstanding any other provision of this Agreement, the Company makes no representation or warranty and shall have no liability to Executive or to any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A but do not satisfy an exemption from, or the conditions of, that section.

The Parties agree that any material or immaterial changes to this Agreement shall not extend the deadline for the occurrence of the Effective Date.
