Secured Party may buy any part or all of the Collateral at any public sale and, if any part or all of the Collateral is of a type customarily sold in a recognized market or is of the type which is the subject of widely distributed standard price quotations, Secured Party may buy such Collateral at private sale and in each case may make payment therefor by any means, whether by credit against the Obligations or otherwise. Secured Party may apply the cash proceeds actually received from any sale or other disposition to the reasonable and documented expenses of retaking, holding, preparing for sale, selling, leasing and the like, to reasonable and documented external attorneys’ fees and all legal, travel and other expenses which may be incurred by Secured Party in attempting to collect the Obligations, proceed against the Collateral or enforce this Security Agreement or in the prosecution or defense of any action or proceeding related to the Obligations, the Collateral or this Security Agreement; and then to the Obligations in such order and as to principal or interest as Secured Party may desire; and Debtor shall remain liable and will pay Secured Party on demand for any deficiency remaining, together with interest thereon at the highest rate then payable on the Obligations and the balance of any expenses unpaid, with any surplus to be paid to Debtor, subject to any duty of Secured Party imposed by law to the holder of any subordinate security interest in the Collateral known to Secured Party. (b) Secured Party may, at any time and from time to time, as appropriate, after the occurrence and during the continuance of a Default set off and apply to the payment of the Obligations, any Collateral in or coming into the possession of Secured Party or their agents, without notice to Debtor and in such manner as Secured Party may in their discretion determine. 6. Secured Party and Debtor may mutually designate and appoint a collateral agent (“Agent”), as attorney-in-fact of Debtor, irrevocably and with power of substitution, with authority to do anything which the Debtor is required to do under this Security Agreement in relation to the creation, administration, protection, preservation or enforcement of the rights of the Secured Party in the Collateral, including: endorse the name of Debtor on any notes, acceptances, checks, drafts, money orders, instruments or other evidences of Collateral that may come into Secured Party’s possession; sign the name of Debtor on any invoices, documents, assignments; execute proofs of claim and loss; execute endorsements, assignments or other instruments of conveyance or transfer; and adjust and compromise any claims under insurance policies or otherwise; execute releases. Neither Secured Party nor the Agent shall be liable for any acts of commission or omission done in good faith, for any error of judgment or for any mistake of fact or law. This power of attorney being coupled with an interest is irrevocable while any Obligations shall remain unpaid. 7. With respect to the enforcement of Secured Party’s rights under this Security Agreement, absent gross negligence, fraud or willful misconduct by the Secured Party or the Agent as determined by a court of competent jurisdiction by final and non-appealable judgment, Debtor hereby releases Secured Party and Agent from any claims, causes of action and demands at any time arising out of or with respect to this Security Agreement, the Obligations, the Collateral and its use and/or any actions taken or omitted to be taken by Secured Party or Agent in good faith

5 4165-0321-4930.3 with respect thereto, and Xxxxxx xxxxxx agrees to hold Secured Party and Agent harmless from and with respect to any and all such claims, causes of action and demands. 8. Debtor agrees to use commercially reasonable efforts to obtain all necessary consents in order to facilitate the inclusion of any intellectual property jointly owned by third parties as Collateral, within a hundred and twenty (120) days following the date hereof; provided that such a hundred and twenty (120) day period shall be automatically extended in additional thirty (30) day increments so long as Debtor is using commercially reasonable efforts to obtain such consents. 9. Secured Party’s prior recourse to any Collateral shall not constitute a condition of any demand, suit or proceeding for payment or collection of the Obligations nor shall any demand, suit or proceeding for payment or collection of the Obligations constitute a condition of any recourse by Secured Party to the Collateral. Any suit or proceeding by Secured Party to recover any of the Obligations shall not be deemed a waiver of, or bar against, subsequent proceedings by Secured Party with respect to any other Obligations and/or with respect to the Collateral. No act, omission or delay by Secured Party shall constitute a waiver of their rights and remedies hereunder or otherwise. No single or partial waiver by Secured Party of any covenant, warranty, representation, Default or right or remedy which they may have shall operate as a waiver of any other covenant, warranty, representation, Default, right or remedy or of the same covenant, warranty, representation, Default, right or remedy on a future occasion. Debtor hereby waives presentment, notice of dishonor and protest of all instruments included in or evidencing any Obligations or Collateral, and all other notices and demands whatsoever (except as expressly provided herein). 10. Debtor hereby agrees to pay, on demand, all reasonable and documented out-of- pocket expenses incurred by Secured Party in connection with the enforcement of the Notes, this Security Agreement, and the Obligations and in connection with any amendment, including, without limitation, the reasonable fees and disbursements of counsel to Secured Party. 11. In the event of any litigation with respect to any matter connected with this Security Agreement, the Obligations, the Collateral or the Notes, Debtor hereby waives the right to a trial by jury and all rights of setoff. Debtor hereby waives personal service of any process in connection with any such action or proceeding and agrees that the service thereof may be made by certified or registered mail directed to Debtor in accordance with Section 15 of this Security Agreement. In the alternative, Secured Party may in their discretion effect service upon Debtor in any other form or manner permitted by law. 12. Upon the payment in full of the Notes and satisfaction of all Obligations in accordance with the Notes, this Security Agreement and the security interest granted hereby in the Collateral shall terminate and all rights to the Collateral under this Agreement shall revert to Debtor. Upon any such termination, the Debtor shall have the right to file UCC–3 financing statement releases or other documents of release reasonably required to reflect the termination of the security interest contemplated hereby. 13. Secured Party may assign their rights and obligation hereunder to any Affiliate of Secured Party, provided that such Affiliate assumes all of the liabilities or obligations of Secured

6 4165-0321-4930.3 Party hereunder. For purposes of this section, “Affiliate” of any person means any other person or entity which, directly or indirectly, controls or is controlled by that person, or is under common control with that person or entity. “Control” (including, with correlative meaning, the terms “controlled by” and “under common control with”), as used with respect to any person or entity, means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of such person or entity, whether through the ownership of voting securities, by contract or otherwise. 14. All terms herein shall have the meanings as defined in the UCC, or Securities Purchase Agreement unless the context otherwise requires. No provision hereof shall be modified, altered, waived, released, terminated or limited except by a written instrument expressly referring to this Security Agreement and to such provision, and executed by the party to be charged. The execution and delivery of this Security Agreement has been authorized by any necessary vote or consent of Debtor.

If any term of this Security Agreement shall be held to be invalid, illegal or unenforceable, the validity of all other terms hereof shall in no way be affected thereby. Secured Party is authorized to annex hereto any schedules referred to herein. 15. All notices and other communications under this Agreement shall be in writing and shall be deemed given when delivered personally, by e-mail, by overnight mail or delivery service or mailed by certified mail, return receipt requested, to the parties as set forth in the Notes.
