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.

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

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 

  
 2 








 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 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.
