relating to this Voting Agreement or the enforcement of any provision of this Voting Agreement is brought against any party hereto, the prevailing party shall be entitled to recover reasonable attorneys’ fees, costs and disbursements (in
addition to any other relief to which the prevailing party may be entitled). 
 5.11 Non-Exclusivity. The rights and
remedies of Sorrento under this Voting Agreement are not exclusive of or limited by any other rights or remedies which it may have, whether at law, in equity, by contract or otherwise, all of which shall be cumulative (and not alternative).

 5.12 Governing Law; Jurisdiction; Waiver of Jury Trial. This Voting Agreement and the Proxy shall be construed in
accordance with, and governed in all respects by, the internal laws of the State of Delaware, (without giving effect to principles of conflicts of laws). Any Legal Proceeding (as defined below) relating to this Agreement or the enforcement of any
provision of this Agreement (including a Legal Proceeding based upon intentional or willful misrepresentation or fraud) may be brought or otherwise commenced in any state or federal court located in the State of California. Each party to this
Agreement: (i) expressly and irrevocably consents and submits to the jurisdiction of each state and federal court located in the State of California (and each appellate court located in the State of California) in connection with any such Legal

Proceeding commenced in any state or federal court located in the State of California, any claim that such party is not subject personally to the jurisdiction of such court, that such Legal Proceeding has been brought in an inconvenient forum, that
the venue of such proceeding is improper or that this Agreement or the subject matter of this Agreement may not be enforced in or by such court. For purposes of this section, “Legal Proceeding” shall mean any action, suit,
litigation, arbitration, proceeding (including any civil, criminal, administrative, investigative or appellate proceeding), hearing, inquiry, audit, examination or investigation commenced, brought, conducted or heard by or before, or otherwise

 5.13 Waiver of Jury Trial. Each of the parties hereto hereby irrevocably waives any
and all right to trial by jury in any Legal Proceeding arising out of or related to this Voting Agreement or the transactions contemplated hereby. 
 5.14 Counterparts; Exchanges by Facsimile or Electronic Delivery. This Voting Agreement may be executed in separate counterparts, each of which when so executed and delivered shall be an original,
but all such counterparts shall together constitute one and the same instrument. The exchange of a fully executed Voting Agreement (in counterparts or otherwise) by facsimile or electronic delivery shall be sufficient to bind the parties to the
terms and conditions of this Voting Agreement. 
 5.15 Headings. The headings contained in this Voting Agreement are for
convenience of reference only, shall not be deemed to be a part of this Voting Agreement and shall not be referred to in connection with the construction or interpretation of this Voting Agreement.

(a) extend the time for the performance of any of the obligations or other acts of the other parties to this Voting Agreement; (b) waive any inaccuracy in or breach of any representation, warranty, covenant or obligation of the other party
in this Voting Agreement or in any document delivered pursuant to this Voting Agreement; and (c) waive compliance with any covenant, obligation or condition for the benefit of such party contained in this Voting Agreement. No failure on the
part of any Person to exercise any power, right, privilege or remedy under this Voting Agreement, and no delay on the part of any Person in exercising any power, right, privilege or remedy under this Voting Agreement, shall operate as a waiver of
such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No Person shall be deemed
to have waived any claim arising out of this Voting Agreement, or any power, right, privilege or remedy under this Voting Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument
duly executed and delivered on behalf of such Person; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given. 
 5.17 Independence of Obligations. The covenants and obligations of Stockholder set forth in this Voting Agreement shall be construed as independent of any other contract between Stockholder, on the
one hand, and IgDraSol or Sorrento, on the other. The existence of any claim or cause of action by Stockholder against IgDraSol or Sorrento shall not constitute a defense to the enforcement of any of such covenants or obligations against
Stockholder. Nothing in this Voting Agreement shall limit any of the rights or remedies of Sorrento under the Merger Agreement, or any of the rights or remedies of Sorrento or any of the obligations of Stockholder under any agreement between
Stockholder and Sorrento or any certificate or instrument executed by Stockholder in favor of Sorrento; and nothing in the Merger Agreement or in any other such agreement, certificate or instrument, shall limit any of the rights or remedies of
Sorrento or any of the obligations of Stockholder under this Voting Agreement. 
 5.18 Other Capacities. Notwithstanding
any provision of this Voting Agreement to the contrary, nothing in this Voting Agreement shall limit or restrict Stockholder from acting in good faith in Stockholder’s capacity as a director or officer of IgDraSol (it being understood that this
Voting Agreement shall apply to Stockholder solely in Stockholder’s capacity as a stockholder of IgDraSol).

versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include the masculine and feminine genders.

Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.”

 EXHIBIT A 

FORM OF IRREVOCABLE PROXY 







 IRREVOCABLE PROXY 

The undersigned stockholder (the “Stockholder”) of IgDraSol, Inc., a Delaware corporation (the
“IgDraSol”), hereby irrevocably (to the fullest extent permitted by law) appoints and constitutes Sorrento Therapeutics, Inc., a Delaware corporation (“Sorrento”), and Dr. Henry Ji and Richard Vincent, solely
in their capacities as executive officers of Sorrento, and each of them, the attorneys and proxies of the Stockholder, with full power of substitution and resubstitution, to the full extent of the Stockholder’s rights with respect to the
outstanding shares of capital stock of IgDraSol owned of record by the Stockholder as of the date of this proxy, which shares are specified in this proxy, and all shares of capital stock of IgDraSol that may be owned of record by the Stockholder
after the date of this proxy. (The shares of the capital stock of IgDraSol referred to in the immediately preceding sentence are referred to as the “Shares.”) Upon the execution of this proxy, all prior proxies given by the
Stockholder with respect to any of the Shares are hereby revoked, and the Stockholder agrees that no subsequent proxies inconsistent with this Proxy will be given with respect to any of the Shares. 

This proxy is irrevocable, is coupled with an interest and is granted in connection with, and as security for, the Voting Agreement,
dated as of the date hereof, by and among Sorrento, IgDraSol and the Stockholder (the “Voting Agreement”), and is granted in consideration of Sorrento entering into the Agreement and Plan of Merger, dated as of the date hereof,
among Sorrento, STI Merger Sub Inc., a Delaware corporation, IgDraSol and Vuong Trieu as the Stockholders’ Agent. This proxy will terminate on the Expiration Date (as defined in the Voting Agreement). 

Prior to the Expiration Date, the attorneys and proxies named above will be empowered, and may exercise this proxy, to vote any Shares
owned by the undersigned, at any meeting of the stockholders of IgDraSol, however called, or at any adjournment or postponement thereof and on every action or approval by written consent of the stockholders of IgDraSol: 

(a) in favor of the Merger, the execution and delivery by IgDraSol of the Merger Agreement and the adoption and
approval of the Merger Agreement and the terms thereof, in favor of each of the other actions contemplated by the Merger Agreement and in favor of any action in furtherance of any of the foregoing; 

(b) in favor of any proposal to adjourn or postpone the meeting of the stockholders of IgDraSol to a later date if
there are not sufficient votes for adoption of the Merger Agreement on the date on which such meeting is held; 

(c) against any action or agreement that would result in a material breach of any representation, warranty,
covenant or obligation of IgDraSol in the Merger Agreement; and
