FREQUENTLY ASKED QUESTIONS

PROCESS FOR SHARE PURCHASE FROM OPEN MARKET

1. Once Scilex Dividend Short Holders (the "Buyer") acquire shares of Scilex Holding Company ("Scilex") common stock in the open market, the Buyer will enter into an agreement with Scilex to impose the lock-up restriction expiring September 1, 2023 (the "Lockup") on the purchased shares.

1. The agreement will be a short form letter agreement, pursuant to which the Buyer will agree to the imposition of the Lockup legend (through September 1, 2023) on its shares and Scilex will agree to the waiver under #4 below.
2. Following the open market purchases, Buyer can contact Stephen Ma at Scilex Holding Company, Inc. ([e-mail]) to obtain a copy of the agreement for execution.
3. The agreement will be executed by Scilex and the Buyer or record holder of the acquired shares.
4. If a holder of a short-position already holds unrestricted shares of Scilex common stock, such holder may convert such shares into restricted shares subject to the Lockup via the same process outlined here for Buyers.

2. Scilex and Buyer will jointly instruct Continental Stock Transfer & Trust Company, Scilex's transfer agent ("Continental"), to impose the Lockup on the shares.

3. If the Buyer is using the purchased shares to cover all or a portion of any outstanding short position in Scilex stock, Buyer will instruct Scilex's transfer agent to transfer the shares to the lender of the short position.

1. Buyer, as the holder of the shares, may make direct requests to Continental to transfer the shares. Continental will provide the Buyer with the necessary documentation.
2. Because the shares will have a Lockup, Continental will separately contact Scilex for an instruction to permit the transfer (See #4 below).
3. This same process will apply if the lender is also a borrower of Scilex shares (i.e., short) and, in turn, is returning the lender's borrowed shares to a downstream lender.

4. Scilex will instruct Continental to "waive" application of the Lockup solely for the purpose of Buyer conveying shares to the lender. The Lockup will continue to apply to the returned shares in lender's name. This same process will apply if the lender is also a borrower of Scilex shares (i.e., short) and, in turn, is returning the lender's borrowed shares to a downstream lender.

FAQs

1.What are the expected mechanics to buying stock from Sorrento mentioned in pg. 5, section "Process" option ii

1. How are clients expected to pay Sorrento for Scilex shares?
   
   1. Yes, buyers should expect to wire funds to Sorrento. Wiring instructions will be provided in the Purchase Agreement.
2. How will the shares be received? i.e. DWAC into DTC on CUSIP 80880W106 or book entry at Continental?
   1. Shares will be held in book-entry form at Continental.

2.In regards to shares purchased directly from the company, what restrictions are applied if any?

If restrictions applied, are they above and beyond the original spinoff restriction since they are being directly purchased from the company?

1. The shares will be sold by Sorrento to Buyer pursuant to the Registration Statement on Form S-1 (File No. 333-268603) filed by Scilex with the SEC on November 30, 2022, and declared effective by the SEC on December 27, 2022, and therefore will be transferred by Sorrento in a registered transaction. However, the shares will be subject to a lock-up through September 1, 2023 and therefore are "restricted" from a transfer perspective through the lockup period absent a waiver from Scilex. Upon expiration of the lock-up on 9/1/23 (unless otherwise extended by the Bankruptcy Court), Scilex will instruct its transfer agent to remove the lock- up as of 9/2/23.

About Sorrento Therapeutics, Inc.

Sorrento is a clinical and commercial stage biopharmaceutical company developing new therapies to treat cancer, pain (non-opioid treatments), autoimmune disease, and COVID-19.

Sorrento's commitment to life-enhancing therapies for patients is also demonstrated by our effort to advance a TRPV1 agonist, non-opioid pain management small molecule, resiniferatoxin ("RTX"), and SP-102 (10 mg, dexamethasone sodium phosphate viscous gel) (SEMDEXA), a novel, viscous gel formulation of a widely used corticosteroid for epidural injections to treat lumbosacral radicular pain, or sciatica, and to commercialize ZTlido^® (lidocaine topical system) 1.8% for the treatment of postherpetic neuralgia (PHN). RTX has been cleared for a Phase II trial for intractable pain associated with cancer and a Phase II trial in osteoarthritis patients. Positive final results from the Phase III Pivotal Trial C.L.E.A.R. Program for SEMDEXA, its novel, non-opioid product for the treatment of lumbosacral radicular pain (sciatica), were announced in March 2022. ZTlido^® was approved by the FDA on February 28, 2018.
