immediately before consummation of such transaction or series of related transactions do not, immediately after consummation of such transaction or series of related transactions, retain Stock representing at least 50% of the voting power of the

entity, (iii) the sale, license or other disposition of all or substantially all of Your assets, or (iv) the occurrence of any “Extraordinary Transaction” (or similar defined term) under and as defined in any of the 2013 Warrant

 2. Representations and Warranties. Guarantor hereby represents and warrants to Secured
Party that each of the representations and warranties contained in Section 4 of the Security Agreement are true and correct in all material respects as of the date hereof, except such representations and warranties that relate expressly to an
earlier date, in which case they are true and correct in all material respects as of such earlier date, in each case, after giving effect to this Amendment. 

3. Conditions to Effectiveness. This Amendment shall be effective upon receipt by Secured Party of this Amendment duly executed by the
parties hereto. 
 4. Recitals. The recitals to this Amendment shall constitute a part of the agreement of the parties hereto. 

5. Consent to Jurisdiction and Venue. All judicial proceedings arising in or under or related to this Amendment may be brought in any
state or federal court of competent jurisdiction located in the State of California. By execution and delivery of this Amendment, each party hereto generally and unconditionally: (a) consents to personal jurisdiction in San Mateo County, State
of California; (b) waives any objection as to jurisdiction or venue in San Mateo County, State of California; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d) irrevocably
agrees to be bound by any judgment rendered thereby in connection with this Amendment. 
 6. Entire Agreement. This Amendment,
together with the Security Agreement and the other Loan Documents, is the entire agreement between the parties hereto with respect to the subject matter hereof. This Amendment supersedes all prior and contemporaneous oral and written agreements and
discussions with respect to the subject matter hereof. 
 7. Mutual Waiver Of Jury Trial; Judicial Reference. Because disputes
arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and expert person and The Parties wish applicable state and federal laws to apply (rather than arbitration rules), The Parties
desire that their disputes be resolved by a judge applying such applicable laws. TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE PARTIES SPECIFICALLY WAIVES ANY RIGHT THEY MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM,
COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY YOU AGAINST US OR OUR ASSIGNEE OR BY US OR OUR ASSIGNEE AGAINST YOU. IN THE EVENT THAT THE FOREGOING JURY TRIAL WAIVER IS NOT ENFORCEABLE, ALL CLAIMS,
INCLUDING ANY AND ALL QUESTIONS OF LAW OR FACT RELATING THERETO, SHALL, AT THE WRITTEN REQUEST OF ANY PARTY, BE DETERMINED BY JUDICIAL REFERENCE PURSUANT TO THE CALIFORNIA CODE OF CIVIL PROCEDURE (“REFERENCE”). THE PARTIES SHALL SELECT A
SINGLE NEUTRAL REFEREE, WHO SHALL BE A RETIRED STATE OR FEDERAL JUDGE. IN THE EVENT THAT THE PARTIES CANNOT AGREE UPON A REFEREE, THE REFEREE SHALL BE APPOINTED BY THE COURT. THE REFEREE SHALL REPORT A STATEMENT OF DECISION TO THE COURT. NOTHING IN
THIS SECTION SHALL LIMIT THE RIGHT OF ANY PARTY AT ANY TIME TO EXERCISE LAWFUL SELF-HELP REMEDIES, FORECLOSE AGAINST COLLATERAL OR OBTAIN PROVISIONAL REMEDIES. THE PARTIES SHALL BEAR THE FEES AND EXPENSES OF THE REFEREE EQUALLY UNLESS THE REFEREE
ORDERS OTHERWISE. THE 

  
 3 








 
REFEREE SHALL ALSO DETERMINE ALL ISSUES RELATING TO THE APPLICABILITY, INTERPRETATION, AND ENFORCEABILITY OF THIS SECTION. THE PARTIES ACKNOWLEDGE THAT THE CLAIMS WILL NOT BE ADJUDICATED BY A
JURY. THIS WAIVER EXTENDS TO ALL SUCH CLAIMS, INCLUDING CLAIMS THAT INVOLVE PERSONS OTHER THAN YOU AND US; CLAIMS THAT ARISE OUT OF OR ARE IN ANY WAY CONNECTED TO THE RELATIONSHIP BETWEEN YOU AND US; AND ANY CLAIMS FOR DAMAGES, BREACH OF CONTRACT,
SPECIFIC PERFORMANCE, OR ANY EQUITABLE OR LEGAL RELIEF OF ANY KIND, ARISING OUT OF THIS AGREEMENT. 
 8. Signatures. This Amendment
may be executed in any number of counterparts, each of which will be deemed an original, but all such counterparts together constitute one and the same instrument. This Amendment may be executed and delivered by facsimile or transmitted
electronically in either Tagged Image Format Files (“TIFF”) or Portable Document Format (“PDF”) and, upon such delivery, the facsimile, TIFF or PDF signature, as applicable, will be deemed to have the same effect as
if the original signature had been delivered to the other party. 
 9. Costs and Expenses. Guarantor reaffirms its obligations to
pay, in accordance with the terms of Section 19 of the Security Agreement, all reasonable costs and expenses of Secured Party in connection with the preparation, negotiation, execution and delivery of this Amendment and all other Loan Documents
entered into in connection herewith. 
 10. Effect. Upon the effectiveness of this Amendment, from and after the date hereof, each
reference in the Security Agreement to “this Agreement,” “hereunder,” “hereof,” or words of like import shall mean and be a reference to the Security Agreement as amended hereby and each reference in the other Loan
Documents to the Security Agreement, “thereunder,” “thereof,” or words of like import shall mean and be a reference to the Security Agreement as amended hereby. 

11. Conflict of Terms. In the event of any inconsistency between the provisions of this Amendment and any provision of the Security
Agreement, the terms and provisions of this Amendment shall govern and control.
