4. WITHHOLDING OBLIGATIONS.

(a) Regardless of any action taken by the Company or, if different, the Affiliate to which you provide Continuous Service (the “Service Recipient”) with respect to any income tax, social insurance, payroll tax, fringe benefits tax, payment on account, or other tax-related items associated with the grant, vesting or exercise of the Option or sale of the underlying Common Stock or other tax-related items related to your participation in the Plan and legally applicable to you (the “Tax Liability”), you hereby acknowledge and agree that the Tax Liability is your ultimate responsibility and may exceed the amount, if any, actually withheld by the Company or the Service Recipient. You further acknowledge that the Company and the Service Recipient (i) make no representations or undertakings regarding any Tax Liability in connection with any aspect of this Option, including, but not limited to, the grant, vesting or exercise of the Option, the issuance of Common Stock pursuant to such exercise, the subsequent sale of shares of Common Stock, and the payment of any dividends on the shares; and (ii) do not commit to, and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate your Tax Liability or achieve a particular tax result. Further, if you are subject to Tax Liability in more than one jurisdiction, you acknowledge that the Company and/or the Service Recipient (or former service recipient, as applicable) may be required to withhold or account for Tax Liability in more than one jurisdiction.

(b) Prior to any relevant taxable or tax withholding event, as applicable, you agree to make adequate arrangements satisfactory to the Company and/or the Service Recipient to satisfy all Tax Liability. As further provided in Section 8 of the Plan, you hereby authorize the Company and any applicable Service Recipient to satisfy any applicable withholding obligations with regard to the Tax Liability by one or a combination of the following methods: (i) causing you to pay any portion of the Tax Liability in cash or cash equivalent in a form acceptable to the Company; (ii) withholding from any compensation otherwise payable to you by the Company or the Service Recipient; (iii) withholding from the proceeds of the sale of shares of Common Stock issued upon exercise of the Option (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company, or by means of the Company acting as your agent to sell sufficient shares of Common Stock for the proceeds to settle such withholding requirements, on your behalf pursuant to this authorization without further consent); (iv) withholding shares of Common Stock otherwise issuable to you upon the exercise of the Option, provided that to the extent necessary to qualify for an exemption from application of Section 16(b) of the Exchange Act, if applicable, such share withholding procedure will be subject to the express prior approval of the Board or the Company’s Compensation Committee; and/or (v) any other method determined by the Company to be in compliance with Applicable Law. Furthermore, you agree to pay the Company or the Service Recipient any amount the Company or the Service Recipient may be required to withhold, collect or pay as a result of your participation in the Plan or that cannot be satisfied by the means previously described. In the event it is determined that the amount of the Tax Liability was greater than the amount withheld by the Company or the Service Recipient, you agree to indemnify and hold the Company and/or the Service Recipient (as applicable) harmless from any failure by the Company or the applicable Service Recipient to withhold the proper amount.

3

(c) The Company may withhold or account for your Tax Liability by considering statutory withholding amounts or other withholding rates applicable in your jurisdiction(s), including (i) maximum applicable rates in your jurisdiction(s), in which case you may receive a refund of any over-withheld amount in cash (whether from applicable tax authorities or the Company) and you will have no entitlement to the equivalent amount in Common Stock or (ii) minimum or such other applicable rates in your jurisdiction(s), in which case, you may be solely responsible for paying any additional Tax Liability to the applicable tax authorities or to the Company and/or the Service Recipient. If the Tax Liability withholding obligation is satisfied by withholding shares of Common Stock, for tax purposes, you are deemed to have been issued the full number of shares of Common Stock subject to the exercised portion of the Option, notwithstanding that a number of the shares of Common Stock is held back solely for the purpose of paying such Tax Liability.

(d) You acknowledge that you may not be able to exercise your Option, even though the Option is vested, and that the Company shall have no obligation to issue shares of Common Stock, in each case, unless, and until you have fully satisfied any applicable Tax Liability, as determined by the Company. Unless any withholding obligation for the Tax Liability is satisfied, the Company shall have no obligation to deliver to you any Common Stock in respect of the Option.

5. TRANSFERABILITY. Except as otherwise provided in the Plan, your Option is not transferable, except by will or by the applicable laws of descent and distribution, and is exercisable during your life only by you.

6. RIGHTS AS AN OPTIONHOLDER. Until the date on which all payments and all obligations under that certain Senior Secured Promissory Note, dated as of September 21, 2023, issued by Scilex to Oramed Pharmaceuticals, Inc., a Delaware corporation (“Oramed”), have been paid in full in cash (the “Release Date”), your Option will not be or become exercisable, eligible for exchange, redemption or repurchase, eligible to participate in any dividends or distributions (including the proceeds of any Corporate Transaction) or have any voting rights in respect of the Company or any of its current or future Subsidiaries, and following the closing of the transactions contemplated by the Merger Agreement, the Company, Parent or any of their respective current and future subsidiaries, successors and assigns.

7. CORPORATE TRANSACTION. Your Option is subject to the terms of any agreement governing a Corporate Transaction involving the Company, including, without limitation, a provision for the appointment of a stockholder representative that is authorized to act on your behalf with respect to any escrow, indemnities and any contingent consideration.

8. NO LIABILITY FOR TAXES. As a condition to accepting the Option, you hereby (a) agree to not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from the Option or other Company compensation and (b) acknowledge that you were advised to consult with your own personal tax, financial and other legal advisors regarding the tax consequences of the Option, and have either done so, or knowingly and voluntarily declined to do so. Additionally, you acknowledge that the Option is exempt from Section 409A, only if the exercise price is at least equal to the “fair market value” of the Common Stock on the date of grant as determined by the Internal Revenue Service, and there is no other

4

impermissible deferral of compensation associated with the Option. Additionally, as a condition to accepting the Option, you agree not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates in the event that the Internal Revenue Service asserts that such exercise is less than the “fair market value” of the Common Stock on the date of grant as subsequently determined by the Internal Revenue Service.

9. OBLIGATIONS; RECOUPMENT. You hereby acknowledge that the grant of your Option is additional consideration for any obligations (whether during or after employment) that you have to the Company not to compete, not to solicit its customers, clients or employees, not to disclose or misuse confidential information or similar obligations. Accordingly, if the Company reasonably determines that you breached such obligations, in addition to any other available remedy, the Company may, to the extent permitted by Applicable Law, recoup any income realized by you with respect to the exercise of your Option within two years of such breach. In addition, to the extent permitted by Applicable Law, this right to recoupment by the Company applies in the event that your employment is terminated for Cause, or if the Company reasonably determines that circumstances existed that it could have terminated your employment for Cause.

10. INVESTMENT REPRESENTATIONS. You represent to the Company the following:

(a) Your receipt of the Option and any acquisition of shares of Common Stock issuable pursuant to the Option are for investment for your own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act.

(b) You understand that the Option and the shares of Common Stock issuable pursuant to the Option have not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of your investment intent as expressed herein.

(c) You further acknowledge and understand that the shares issuable pursuant to the Option must be held indefinitely unless the shares are subsequently registered under the Securities Act or an exemption from such registration is available. You further acknowledge and understand that the Company is under no obligation to register such shares.

(d) You are familiar with the provisions of Rules 144 and 701, under the Securities Act, as in effect from time to time, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer thereof (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of issuance of the securities, such issuance will be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the securities exempt under Rule 701 may be sold by you 90 days thereafter, subject to the satisfaction of certain of the conditions specified by Rule 144 and the terms of the Option Agreement.

5

(e) In the event that the Option or the shares of Common Stock issuable pursuant to the Option do not qualify under Rule 701 at the time of issuance, then any shares acquired hereunder, if then otherwise transferable, may be resold by you in certain limited circumstances subject to the provisions of Rule 144, which requires, among other things: (i) the availability of certain public information about the Company, and (ii) the resale occurring following the required holding period under Rule 144 after you have purchased, and made full payment of (within the meaning of Rule 144), the securities to be sold.

(f) You further understand that at the time you wish to sell the shares of Common Stock acquired upon exercise of the Option there may be no public market upon which to make such a sale, and that, even if such a public market then exists, the Company may not be satisfying the current public current information requirements of Rule 144 or 701, and that, in such event, you would be precluded from selling such shares under Rule 144 or 701 even if the minimum holding period requirement had been satisfied.

(g) You further warrant and represent that you have (i) preexisting personal or business relationships with the Company and at least one of its officers, directors or controlling persons, and (ii) the capacity to protect your own interests in connection with the Option and the shares of Common Stock issuable pursuant to the Option by virtue of your business or financial expertise or that of your professional advisors who are unaffiliated with, and who are not compensated by, the Company or any of its affiliates, directly or indirectly.

11. SEVERABILITY. If any part of this Option Agreement or the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Option Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Option Agreement (or part of such a Section) so declared to be unlawful or invalid, will, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible, while remaining lawful and valid.

12. MODIFICATIONS. Until the Release Date, this Option Agreement may not be amended or modified at any time, nor may any rights hereunder be accelerated or any obligations hereunder be waived.

13. BINDING EFFECT; THIRD PARTY BENEFICIARY. Except as provided in this Section 13, this Option Agreement is for the sole benefit of the parties hereto and their respective heirs, legatees, legal representatives, successors, transferees, and assigns, and nothing in this Option Agreement shall give or be construed to give to any person, other than the parties hereto and their respective heirs, legatees, legal representatives, successors, transferees, and assigns, any legal or equitable rights hereunder, whether as third-party beneficiaries or otherwise. Notwithstanding the foregoing, you and the Company acknowledge that Oramed shall be an intended third-party beneficiary of this Option Agreement with respect to Sections 6 and 12 of this Option Agreement and shall be entitled to assert any claims and enforce Sections 6 and 12 of this Option Agreement in law or in equity the same as if it were party hereto.

14. INDEBTEDNESS TO THE COMPANY. In the event that you have any loans, draws, advances or any other indebtedness owing to the Company at the time of exercise of all or a portion of the Option, the Company may deduct and not deliver that number of shares of Common Stock with a Fair Market Value subject to the Option equal to such indebtedness to satisfy all or a portion of such indebtedness, to the extent permitted by law and in a manner consistent with Section 409A of the Code, if applicable.
