Binding Term Sheet

for the Acquisition of ACEA Therapeutics, Inc. by

Sorrento Therapeutics, Inc.

October 14, 2020

This Term Sheet (“Term Sheet”) sets forth certain non-binding understandings and certain binding agreements regarding the proposed acquisition of ACEA Therapeutics, Inc. (“ACEA”) by Sorrento Therapeutics, Inc. (“Sorrento”).  Collectively ACEA and Sorrento are “Parties”.    

As promptly as practicable following the acceptance, execution and delivery of this Term Sheet by Sorrento, the Parties would expect to commence negotiations to enter into a definitive agreement regarding the Transaction (as defined below) (the “Definitive Agreement”).

Upon execution by Sorrento of this Term Sheet, the Sections numbered 1 and 4 through 6 of this Term Sheet (collectively, the “Nonbinding Provisions”) reflect the Parties’ mutual understanding of the matters described in such sections.  Each Party acknowledges that the Nonbinding Provisions are not intended to, and do not, create or constitute any legally binding obligation between Sorrento and ACEA.  The Parties do not intend to be bound by any agreement, and neither Sorrento nor ACEA shall have any liability to the other Party with respect to the Nonbinding Provisions, until the Definitive Agreement is executed and delivered by and between all Parties.  Upon execution by Sorrento of this Term Sheet, the Sections numbered 2, 3 and 7 through 15 of this Term Sheet (collectively, the “Binding Provisions”) will constitute the legally binding and enforceable agreements of Sorrento and ACEA in recognition of the significant costs to be borne by each in pursuing the Transaction and further in consideration of their mutual undertakings as to the matters described herein.

Section

1.   Acquisition

Sorrento would acquire 100% of the outstanding equity securities of ACEA by means of a reverse triangular merger in which a newly-formed subsidiary of Sorrento would be merged with and into ACEA (the “Transaction”). As a result of the Transaction, ACEA would become a wholly owned subsidiary of Sorrento.   The Parties recognize the structure of the Transaction is subject to continuing review and analysis and that it may be necessary or appropriate to change the structure as a result of tax, accounting or other considerations, as may be mutually agreed.

Section
2. Merger Consideration	The consideration payable by Sorrento shall be comprised of a $38 million upfront payment upon completion of the Transaction, License Agreement Payments (as defined below), Royalty Payments (as defined below) and $265 million in additional milestone-based contingent value rights. Sorrento shall acquire all outstanding equity interests of ACEA on a fully-diluted basis. For the purposes of this Term Sheet, fully-diluted basis means all outstanding shares of common and preferred stock of ACEA and assuming the exercise of all options, warrants and rights to exercise or convert outstanding securities of ACEA, if any, at the effective time of the proposed merger (whether or  not then exercisable or vested).  All such shares, options, warrants, and other rights shall be canceled and converted into the right to receive a portion of the merger consideration, less the exercise price thereof (if applicable).   Except as otherwise provided herein, Sorrento may, in its sole and absolute discretion, elect to make any payments referenced herein, including the Upfront Payments (as defined below) and settlement of any of the CVRs (as defined below), in either cash or shares of Sorrento common stock or a combination of cash and shares of Sorrento common stock, based on an exchange ratio to be agreed by the Parties. If Sorrento elects to satisfy any such payments, including the Upfront Payments and settlement of any of the CVRs, in shares of Sorrento common stock, then following any such issuance, Sorrento shall file a resale registration statement with the Securities and Exchange Commission to register for resale such shares of Sorrento common stock.  In the event Sorrento satisfies all or a portion of the foregoing consideration payments through the delivery to ACEA’s equityholders of shares of Sorrento common stock (the “Consideration Shares”), the price per share of the Consideration Shares (the “Consideration Per-Share Price”) used for calculating the number of the Consideration Shares to be issued to ACEA’s equityholders shall be the volume weighted average price of the shares of common stock of Sorrento traded on The NASDAQ Stock Market LLC for ten (10) trading days ending on the date that is three (3) trading days prior to the applicable date of issuance. If the Consideration Per-Share Price is greater than the closing price per share of Sorrento common stock, as reported on The Nasdaq Stock Market LLC on the date that is six (6) months after the date of issuance of Consideration Shares (the “Consideration Payment 6-Month Price”), as applicable, Sorrento shall reimburse ACEA’s equityholders for the difference in value through (a) the payment of cash, (b) the delivery of additional shares of Sorrento common stock valued at the Consideration Payment 6-Month Price or (c) a combination of the foregoing.
	Upfront Payment Sorrento shall make the following payments within ten (10) days of closing the Transaction (collectively, the “Upfront Payments”): (1)$36 million, in respect of existing shareholder loans to be paid directly to the bridge lenders, which shall be paid in shares of Sorrento common stock; and (2)the remainder of the consideration shall be payable to ACEA’s  equityholders.
