SCILEX HOLDING COMPANY SEVERANCE AND CHANGE IN CONTROL AGREEMENT

Exhibit 10.13

SCILEX HOLDING COMPANY

SEVERANCE AND CHANGE IN CONTROL AGREEMENT

This Severance and Change in Control Agreement (the “Agreement”) is made and entered into by and between Xxxxx Xx (“Executive”) and Scilex Holding Company, a Delaware corporation (the “Company”), effective as of November 9, 2023 (the “Effective Date”).

RECITALS

A. The Compensation Committee (the “Committee”) of the Board of Directors of the Company (the “Board”) believes that it is in the best interests of the Company and its stockholders (i) to assure that the Company will have the continued dedication and objectivity of Executive, notwithstanding the possibility, threat, or occurrence of a Change in Control and (ii) to provide Executive with an incentive to continue Executive’s employment prior to a Change in Control and to motivate Executive to maximize the value of the Company upon a Change in Control for the benefit of its stockholders.

B. The Committee believes that it is imperative to provide Executive with certain severance benefits upon Executive’s termination of employment under certain circumstances or benefits in the event of a Change in Control. These benefits will provide Executive with enhanced financial security and incentive and encouragement to remain with the Company notwithstanding the possibility of a Change in Control.

C. Certain capitalized terms used in the Agreement are defined in Section 6 below.

AGREEMENT

NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties hereto agree as follows:

1. Term of Agreement. This Agreement will have an initial term of three (3) years commencing on the Effective Date (the “Initial Term”). On the third anniversary of the Effective Date, this Agreement will renew automatically for additional one (1) year terms (each an “Additional Term”), unless either party provides the other party with written notice of non-renewal at least sixty (60) days prior to the date of automatic renewal. If Executive becomes entitled to benefits under Section 3 during the term of this Agreement, the Agreement will not terminate until all of the obligations of the parties hereto with respect to this Agreement have been satisfied.

2. At-Will Employment. The Company and Executive acknowledge that Executive’s employment is and will continue to be at-will, as defined under applicable law. As an at-will employee, either the Company or Executive may terminate the employment relationship at any time, with or without Cause.

3. Severance and Change in Control Benefits.

(a) Termination Prior to a Change in Control. If the Company terminates Executive’s employment without Cause (excluding death or Disability) or if Executive resigns from employment with the Company for Good Reason and such termination occurs prior to a Change in Control, then subject to Section 4, Executive will receive the following:

(i) Accrued Compensation. The Company will pay Executive all accrued but unpaid vacation (if any), expense reimbursements, wages, and other benefits due to Executive under any Company-provided plans, policies, and arrangements.

(ii) Severance Payments. The Company will provide Executive with continuing severance payments at a rate equal to Executive’s base salary rate, as then in effect, for twelve (12) months from the date of such termination of employment, to be paid periodically in accordance with the Company’s normal payroll policies.

(iii) Continued Benefits Coverage. If Executive elects continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“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 (A) a period of twelve (12) months from the date of termination, (B) the date on which Executive is no longer eligible for COBRA coverage or (C) the date on which Executive and/or Executive’s eligible dependents become covered under similar plans. The reimbursements will be made by the Company to Executive consistent with the Company’s normal expense reimbursement policy; provided, however, Executive must submit proof of payment within thirty (30) days of paying the applicable premium. Notwithstanding the first sentence of this Section 3(a)(iii), 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 in 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 twelve (12) 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.

(iv) Extended Post-Termination Exercise Period. Notwithstanding any other provision in any applicable equity compensation plan and/or award agreement, Executive’s outstanding and vested stock options as of the date of Executive’s termination of employment will remain exercisable until the date that is twenty-four (24) months following the date of Executive’s

-2-

termination of employment; provided, however, that the post-termination exercise period for any individual stock option will not extend beyond its original maximum term.

If Executive’s employment with the Company terminates (A) due to a voluntary resignation by Executive other than for Good Reason, (B) due to a termination for Cause by the Company or (C) due to Executive's death or Disability, then Executive will not be entitled to receive severance or other benefits pursuant to Section 3(a) other than the accrued benefits set forth in Section 3(a)(i).

(b) Change in Control Benefits. In the event that a Change in Control occurs prior to the date on which Executive’s employment with the Company terminates, then subject to Section 4, Executive will receive the following:

(i) Lump-Sum Payment. Executive will receive a lump-sum payment (less applicable withholding taxes) equal to (A) three (3) times the sum of Executive’s annual base salary and target annual bonus, each as in effect immediately prior to the Change in Control, plus (B) $3,000 multiplied by thirty-six (36), in respect of an estimate of benefit premiums for Executive. The lump-sum amount shall be payable as soon as practicable following (and in no event later than seventy-five (75) days after) the date on which the Change in Control occurs.

(ii) Accelerated Vesting of Equity Awards with Time-Based Vesting. One hundred percent (100%) of Executive’s then-outstanding and unvested Equity Awards with solely time-based vesting will become vested in full upon a Change in Control (with the right to receive any settlement for such vested Equity Awards subject to the release requirements set forth in Section 4). For outstanding and unvested Equity Awards with performance-based vesting, all performance goals and other vesting criteria will be treated as set forth in Executive’s Equity Award agreement evidencing such Equity Award and the equity plan pursuant to which such Equity Award was granted and all time-based vesting criteria of such awards, if any, shall be deemed satisfied in full.

(iii) Extended Post-Termination Exercise Period. Notwithstanding any other provision in any applicable equity compensation plan and/or award agreement, each of Executive’s outstanding and vested stock options will remain exercisable for the longer of (A) twenty-four (24) months following the date on which the Change in Control occurs or (B) as otherwise provided in the plan and award agreement evidencing the stock option, but in no event shall an option be exercisable after the expiration of its original maximum term.

(c) Exclusive Remedy. In the event of a termination of Executive’s employment or a Change in Control as set forth in Section 3(a) or Section 3(b) of this Agreement, respectively, the provisions of Section 3 are intended to be and are exclusive and in lieu of any other rights or remedies to which Executive or the Company otherwise may be entitled, whether at law, tort or contract, in equity, or under this Agreement (other than the payment of accrued but unpaid wages, as required by law, and any unreimbursed reimbursable expenses). Executive will be entitled to no benefits, compensation or other payments or rights upon a termination of employment or Change in Control other than those benefits expressly set forth in Section 3 of this Agreement. However, for the avoidance of doubt, the amounts payable under the foregoing clause (b) are not intended to replace or

-3-

supersede or mitigate, and shall not replace or supersede or mitigate, any benefits that Executive might be entitled to receive upon a subsequent termination of employment.

4. Conditions to Receipt of Severance.

(a) Release of Claims Agreement. The receipt of any payments or benefits pursuant to Section 3(a) or Section 3(b) of this Agreement (other than the accrued benefits set forth in Section 3(a)(i) of this Agreement) is subject to Executive signing and not revoking a separation agreement (for a termination pursuant to Section 3(a)) and release of claims in a form prescribed by the Company (the “Release”), which must become effective and irrevocable no later than the sixtieth (60th) day following Executive’s termination of employment (for payments or benefits pursuant to Section 3(a) of this Agreement) or the date on which the Change in Control occurs (for payments or benefits pursuant to Section 3(b) of this Agreement) (the “Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, Executive will forfeit any right to payments or benefits pursuant to Section 3(a) or Section 3(b) of this Agreement. In no event will such payments or benefits be paid or provided until the Release actually becomes effective and irrevocable.

(b) Proprietary Information and Inventions Agreement. Executive’s receipt of any payments or benefits under Section 3 (other than the accrued benefits set forth in Section 3(a)(i)) will be subject to Executive continuing to comply with the terms of the Employee Confidential Information and Inventions Assignment Agreement dated October 26, 2023, between the Company and Executive, as such agreement may be amended from time to time.

(c) Section 409A.

(i) 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 under 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. 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) It is intended that none of the severance payments under this Agreement will constitute Deferred Payments but rather will be exempt from Section 409A as a payment that would fall within the “short-term deferral period” as described in Section 4(c)(iv) below or resulting from an involuntary separation from service as described in Section 4(c)(v) below, to the maximum extent permitted pursuant to Section 409A. However, 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 4(c)(iii). Except as required by Section 4(c)(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

-4-

on the sixtieth (60th) day following Executive’s separation from service and the remaining payments will be made as provided in this Agreement. If any payments or benefits would be considered Deferred Payments that are contingent on the delivery of a release by Executive and could occur in either of two calendar years, the payments or benefits will be provided in the later year.

(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, if any, 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 that is 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 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 under 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) Payments with respect to reimbursements of expenses or benefits or provision of fringe or other in-kind benefits shall be made on or before the last day of the calendar year following the calendar year in which the relevant expense or benefit is incurred. The amount of expenses or benefits eligible for reimbursement, payment or provision during a calendar year shall not affect the expenses or benefits eligible for reimbursement, payment or provision in any other calendar year.

(vii) The foregoing provisions are intended to comply with the requirements of Section 409A so that none of the 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.

5. Limitation on Payments. In the event that the severance and other benefits provided for in this Agreement or otherwise payable to Executive (i) constitute “parachute payments” within the meaning of Section 280G of the Code, and (ii) but for this Section 5, would be subject to the excise tax imposed by Section 4999 of the Code, then Executive’s benefits under Section 3 will be either:

(a) delivered in full, or

(b) delivered as to such lesser extent which would result in no portion of such benefits being subject to excise tax under Section 4999 of the Code,

whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the receipt by 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. If a reduction in severance and other benefits constituting “parachute payments” is necessary so that benefits are delivered to a lesser extent, reduction will occur in the following order: (i) reduction of cash payments; (ii) cancellation of awards granted “contingent on a change in ownership or control” (within the meaning of Code Section 280G), (iii) cancellation of accelerated vesting of Equity Awards; and (iv) reduction of employee benefits. In the event that acceleration of vesting of Equity Award compensation is to be reduced, such acceleration of vesting will be cancelled in the reverse order of the date of grant of Executive’s Equity Awards.

Unless the Company and Executive otherwise agree in writing, any determination required under this Section 5 will be made in writing by the Company’s independent public accountants immediately prior to a Change in Control or such other person or entity to which the parties mutually agree (the “Firm”), whose determination will be conclusive and binding upon Executive and the Company. For purposes of making the calculations required by this Section 5, the Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive will furnish to the Firm such information and documents as the Firm may reasonably request in order to make a determination under this Section. The Company will bear all costs the Firm may incur in connection with any calculations contemplated by this Section 5.

6. Definition of Terms. The following terms referred to in this Agreement will have the following meanings:

(a) Cause. “Cause” has the meaning ascribed to such term in any written agreement between Executive and the Company defining such term and, in the absence of such agreement, such term means, with respect to Executive, the occurrence of any of the following events:

(i) Executive’s theft, dishonesty, willful misconduct, breach of fiduciary duty for personal profit, or intentional falsification of any Company documents or records;

The determination as to whether Executive is being terminated for Cause will be made in good faith by the Board and will be final and binding on Executive. The foregoing definition does not in any way limit the Company’s ability to terminate Executive’s employment relationship at any time as provided in Section 2 above, and the term “Company” will be interpreted to include any subsidiary, parent, affiliate or successor thereto, if applicable.

(b) Change in Control. “Change in Control” means the occurrence in a single transaction or in a series of related transactions, of any one or more of the following events:

Notwithstanding the foregoing or any other provision of this Agreement, (A) the term Change in Control shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written agreement between the Company or any affiliate and Executive shall supersede the foregoing definition with respect to Equity Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth in such an individual written agreement, the foregoing definition shall apply.

10. 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, stockholder 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 1281.8 (the “Act”), and pursuant to California law. The Federal Arbitration Act will 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 Judicial Arbitration & Mediation Services, Inc. (“JAMS”), pursuant to its Employment Arbitration Rules & Procedures (the “JAMS Rules”). The arbitrator will 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 will have the power to award any remedies available under applicable law, and the arbitrator will award attorneys’ fees and costs to the prevailing party, except as prohibited by law. The Company will pay for any administrative or hearing fees charged by the administrator or JAMS, and

-11-

all arbitrator’s fees, except that Executive will pay any filing fees associated with any arbitration that Executive initiates, but only so much of the filing fee as Executive would have instead paid had Executive filed a complaint in a court of law. Executive agrees that the arbitrator will 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 will 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 JAMS Rules conflict with California law, California law will take precedence. The decision of the arbitrator will be in writing. Any arbitration under this Agreement will be conducted in Santa Clara County, California.

(d) Remedy. Except as provided by the Act, arbitration will 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) 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.

(f) 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.

11. Miscellaneous Provisions.

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

(b) Waiver. No provision of this Agreement will be modified, waived or discharged unless the modification, waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company (other than Executive).
