otherwise limited by that prohibition. The Security Interest granted herein shall terminate in accordance with Section 7.1 hereof. 

Section 2.2. Financing Statements; Further Assurances.

(iii) upon the reasonable request of the Secured Party, file such additional financing statements and other documents, including amendments
to the financing statements, in order to maintain the Liens in the Collateral. 
 (c) Until the Obligations are paid and performed in full,

Permitted Liens: (i) after an Event of Default, file or cause to be filed such applications and take such other actions as the Secured Party (or the Majority in Interest if there is more than one Secured Party) may reasonably request to obtain
the consent or approval of any governmental authority to the rights of the Secured Party hereunder, including, without limitation, the right to sell all the Collateral upon an Event of Default without additional consent or approval from such
governmental authority; (ii) from time to time, either before or after an Event of Default, promptly execute and deliver to the Secured Party all such other assignments, certificates, supplemental documents, and financing statements, and do all

remains outstanding immediately prior to the date hereof (the “Senior Permitted Liens”) or as contemplated in Section 2.1, above; (ii) senior to other Liens granted by the Company in the Collateral after the date hereof;
and (iii) that as between all Secured Party, the Security Interest granted to each Secured Party under this Agreement is pari passu with the Security Interests of the other Secured Party. The priorities specified herein are applicable
irrespective of the time, order or method of attachment or perfection of security interests or the time or order of filing of financing statements. The Secured Party agrees not to seek to challenge, to avoid, to subordinate or to contest or directly
or indirectly to support any other Person in challenging, avoiding, subordinating or contesting in any judicial or other proceeding, including, without limitation, any proceeding involving the Company, the priority, validity, extent, perfection or

respects upon the full and final payment by the Company of the Secured Note or the conversion of the Secured Note into shares of capital stock of the Company, in accordance with the terms of the Secured Note. Further, 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 the Secured Note or otherwise consented to by the Secured Party (or the Majority in Interest if

more than one Secured Party) shall promptly execute and deliver to the Company all documents that the Company shall reasonably request to evidence such termination or release. 

Section 7.2. 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 7.3. 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 or this Agreement is sooner terminated in accordance with Section 7.1; and (ii) inure to the benefit of and be enforceable by the Secured
Party and their successors, transferees, and assigns. The Secured Party may assign its rights hereunder in connection with any private sale or transfer of its Secured Note in accordance with the terms of the Secured Note 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 7.4. Governing Law; Jurisdiction. This Agreement shall be governed by and construed under the laws of the State of New

 Section 7.7. 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 Secured Party, or if there is more than one Secured Party, 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 Party 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 Party under this

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.

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 7.9. 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 7.10. Waivers. The Company
acknowledges that the Obligations arose out of a commercial transaction and hereby knowingly waives any right to require the Secured Party 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 Party, or (iv) make presentment, demand, dishonor, notice of dishonor, acceleration and/or notice of non-payment. 

Section 7.11. Release. No transfer or renewal, extension, assignment or termination of this Agreement or of any instrument or
document executed and delivered by the Company to the Secured Party, nor additional advances made by the Secured Party to the Company, nor the taking of further security, nor the retaking or re-delivery of the Collateral by the Secured Party nor any
other act of the Secured Party shall release the Company from any Obligation, except a release or discharge executed in writing by the Secured Party or the Majority in Interest if there is more than one Secured Party, with respect to such Obligation
or upon full payment and satisfaction of all Obligations and termination of the Secured Note. At such time the Obligations have been satisfied in full, the Secured Party or the Majority in Interest if there is more than one Secured Party, shall
execute and deliver to the Company all assignments and other instruments as may be reasonably necessary or proper to terminate the Secured Party’s security interest in the Collateral, subject to any disposition of the Collateral that may have
been made by or on behalf of the Secured Party pursuant to this Agreement. For the purpose of this Agreement, the Obligations shall be deemed to continue if the Company enters into any bankruptcy or similar proceeding at a time when any amount paid
to the Secured Party 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.
