other agreement or otherwise (other than pursuant to this Agreement), or take or institute any action against the Security Agent or any of the other Secured Parties in respect of the Collateral or its rights hereunder (other than any such action
arising from the breach of this Agreement) and (ii) that such Secured Party has no other rights with respect to the Collateral other than as set forth in this Agreement and the other Transaction Documents. Upon the acceptance of any
appointment as Security Agent hereunder by a successor Security Agent, such successor Security Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Security Agent and the retiring
Security Agent shall be discharged from its duties and obligations under the Agreement. After any retiring Security Agent’s resignation or removal hereunder as Security Agent, the provisions of the Agreement shall inure to its benefit as
to any actions taken or omitted to be taken by it while it was Security Agent. 
 SECTION VIII  

MISCELLANEOUS 

Section 8.1 Termination and Release. Upon the full and final payment and performance of the Obligation, this Agreement shall
automatically terminate. The Liens created by this Agreement on any of the Collateral shall be automatically released if the Company disposes of such Collateral pursuant to a transaction permitted by this Agreement, the Note, the Intercreditor
Agreement or otherwise consented to by the Security Agent or the Majority in Interest. In connection with any termination or release pursuant to this Section 8.1, the Majority in Interest shall cause the Security Agent to promptly execute and
deliver to the Company all documents that the Company shall reasonably request to evidence such termination or release. 
 Section 8.2
Severability. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision;
provided, that in such case the parties shall negotiate in good faith to replace such provision with a new provision which is not illegal, unenforceable or void, as long as such new provision does not materially change the economic benefits
of this Agreement to the parties. 
 Section 8.3 Continuing Security Interest; Successors. This Agreement creates a continuing
security interest in the Collateral and shall (i) remain in full force and effect until the Obligations are paid and performed in full; and (ii) inure to the benefit of and be enforceable by Secured Parties and their successors,
transferees, and assigns. Each Secured Party may assign its rights hereunder in connection with any private sale or transfer of its Note in accordance with the terms of the Subscription Agreement and applicable law, in which case the term
“Secured Party” shall be deemed to refer to such transferee as though such transferee was an original signatory hereto. 

Section 8.4 Governing Law; Jurisdiction. This Agreement shall be governed by and construed under the laws of the State of
California applicable to contracts made and to be performed entirely within the State of California. The Company hereby irrevocably submit to the non-exclusive jurisdiction of the state and federal courts sitting in the City of Los Angeles,
California, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waive, and agree not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper.

 Section 8.5 Headings. The headings used in this Agreement are used for convenience
only and are not to be considered in construing or interpreting this Agreement. 
 Section 8.6 Notices. Any notice to the
Company or to the holder of this Convertible Note shall be given in the manner set forth in the Subscription Agreement; provided that the Holder of this Convertible Note, if not a party to such Subscription Agreement, may specify alternative
notice instructions to the Company. Either party may, by notice given in accordance with the Subscription Agreement, change the address to which notices, demands and requests shall be sent to such party. Any notice to be given by the Company to the
Security Agent shall be given in the manner provided for in the Subscription Agreement, and delivered to such address as the Company is instructed by the Security Agent. 

Section 8.7 Entire Agreement; Amendments; Waivers. This Agreement constitutes the entire agreement between the parties with regard
to the subject matter hereof and thereof, superseding all prior agreements or understandings, whether written or oral, between or among the parties. Except as expressly provided herein, neither this Agreement nor any term hereof may be amended
except pursuant to a written instrument executed by Company and the Majority in Interest, and no provision hereof may be waived other than by a written instrument signed by the party against whom enforcement of any such waiver is sought. The Secured
Parties shall not, by any act, any failure to act or any delay in acting be deemed to have (i) waived any right or remedy under this Agreement, or (ii) acquiesced in any Event of Default or in any breach of any of the terms and conditions
of this Agreement. No failure to exercise, nor any delay in exercising, any right, power or privilege of the Secured Parties under this Agreement shall operate as a waiver of any such right, power or privilege. No single or partial exercise of any
right, power or privilege under this Agreement shall preclude any other or further exercise of any other right, power or privilege. A waiver by a Secured Party of any right or remedy under this Agreement on any one occasion shall not be construed as
a bar to any right or remedy that such Secured Party would otherwise have on any future occasion. 
 Section 8.8 Multiple
Counterparts. This Agreement has been executed in a number of identical counterparts, each of which shall be deemed an original for all purposes and all of which constitute, collectively, one agreement; but, in making proof of this Agreement, it
shall not be necessary to produce or account for more than one such counterpart. 
 Section 8.9 Cumulative Remedies. The rights
and remedies provided in this Agreement are cumulative, may be exercised singly or concurrently, and are not exclusive of any other rights or remedies provided by law. 

Section 8.10 Waivers. The Company acknowledges that the Obligations arose out of a commercial transaction and hereby knowingly
waives any right to require the Secured Parties to (i) proceed against any person or entity, (ii) proceed against any other collateral under any other agreement, (iii) pursue any other remedy available to the Secured Parties, or
(iv) make presentment, demand, dishonor, notice of dishonor, acceleration and/or notice of non-payment.

 Section 8.11 Release. No transfer or renewal, extension, assignment or termination of
this Agreement or of any instrument or document executed and delivered by an Obligor or any other obligor to the Secured Parties, nor additional advances made by the Secured Parties to an Obligor, nor the taking of further security, nor the retaking
or re-delivery of the Collateral to an Obligor by the Secured Parties nor any other act of the Secured Parties shall release either Obligor from any Obligation, except a release or discharge executed in writing by the Secured Parties with respect to
such Obligation or upon full payment and satisfaction of all Obligations and termination of the Notes. At such time the Obligations have been satisfied in full, each Secured Party shall execute and deliver to each Obligor all assignments and other
instruments as may be reasonably necessary or proper to terminate such Secured Party’s security interest in the Collateral, subject to any disposition of the Collateral that may have been made by the Secured Parties pursuant to this Agreement.
For the purpose of this Agreement, the Obligations shall be deemed to continue if either Obligor enters into any bankruptcy or similar proceeding at a time when any amount paid to the Secured Parties could be ordered to be repaid as a preference or
pursuant to a similar theory, and shall continue until it is finally determined that no such repayment can be ordered.
