security interests in all personal property of each Grantor (other than Excluded Collateral). Such recordings and filings and
all other action necessary to perfect and protect such security interest have been duly taken (and, in the case of Collateral
in which any Grantor obtains rights after the date hereof, will be duly taken), except for the Collateral Agent’s having
possession of all Documents, Chattel Paper, Instruments and cash constituting Collateral after the date hereof and the other actions,
filings and recordations described above, including the Perfection Requirements, and except for the execution and delivery of
the Controlled Account Agreements (as defined in the Securities Purchase Agreement).

or a portion of such securities, cash, investments and other items held by such institution. Any such securities, cash,
investments and other items so received by the Collateral Agent shall be applied as specified in accordance with Section

notices, numbers and markings (relating to patent, trademark and copyright rights) and using the Trademarks on each applicable
trademark class of goods in order to so maintain the Trademarks in full force and free from any claim of abandonment for non-use,
and each Grantor will not (nor permit any licensee thereof to) do any act or knowingly omit to do any act whereby any Material

the process of being, discontinued, abandoned or terminated in the ordinary course of business and consistent with the exercise
of reasonable business judgment, (B) that is being replaced with Material Intellectual Property Rights substantially similar to
the Material Intellectual Property Rights that may be abandoned or otherwise become invalid, so long as the failure to use or

statements and schedules further identifying and describing the Material Intellectual Property Rights and such other reports in
connection with the Material Intellectual Property Rights as the Collateral Agent may reasonably request, all in reasonable detail

Inspection and Reporting. Thrice per year, or at any time after an Event of Default has occurred and is continuing, each
Grantor shall permit the Collateral Agent, or any agent or representatives thereof or such professionals or other Persons as the
Collateral Agent may designate (at Grantors’ sole cost and expense) (i) to examine and make copies of and abstracts from
any Grantor’s records and books of account, (ii) to visit and inspect its properties, (iii) to verify materials, leases,
Instruments, Accounts, Inventory and other assets of any Grantor from time to time, and (iv) to conduct audits, physical counts,
appraisals and/or valuations, examinations at the locations of any Grantor. Each Grantor shall also permit the Collateral Agent,
or any agent or representatives thereof or such attorneys, accountants or other professionals or other Persons as the Collateral
Agent may designate to discuss such Grantor’s affairs, finances and accounts with any of its directors, officers, managerial
employees, independent accountants or any of its other representatives. Without limiting the foregoing, the Collateral Agent may,
at any time after an Event of Default has occurred and is continuing, in the Collateral Agent’s own name, in the name of
a nominee of the Collateral Agent, or in the name of any Grantor communicate (by mail, telephone, facsimile or otherwise) with
the Account Debtors of such Grantor, parties to contracts with such Grantor and/or obligors in respect of Instruments of such
Grantor to verify with such Persons, to the Collateral Agent’s satisfaction, the existence, amount, terms of, and any other
matter relating to, Accounts, Instruments, Chattel Paper, payment intangibles and/or other receivables.

(m)
Future Subsidiaries. If any Grantor hereafter creates or acquires any Subsidiary, simultaneously with the creation or acquisition
of such Subsidiary, such Grantor shall (i) if such Subsidiary is a Significant Subsidiary and a Domestic Subsidiary, cause such
Significant Subsidiary to become a party to this Agreement as an additional “Grantor” hereunder, (ii) deliver to the
Collateral Agent updated Schedules to this Agreement, as appropriate (including, without limitation, an updated Schedule IV
to reflect the grant by such Grantor of a Lien on all Pledged Equity now or hereafter owned by such Grantor), (iii) if such
Subsidiary is a Significant Subsidiary and a Domestic Subsidiary, cause such Significant Subsidiary to duly execute and deliver
a guaranty of the Obligations in favor of the Collateral Agent in form and substance acceptable to the Collateral Agent, (iv)
deliver to the Collateral Agent the stock certificates representing all of the Capital Stock of such Subsidiary, along with undated
stock powers for each such certificates, executed in blank (or, if any such shares of Capital Stock are uncertificated, confirmation
and evidence reasonably satisfactory to the Collateral Agent that the security interest in such uncertificated securities has
been transferred to and perfected by the Collateral Agent, in accordance with Sections 8-313, 8-321 and 9-115 of the Code or any
other similar or local or foreign law that may be applicable), and (v) duly execute and/or cause to be delivered to the Collateral
Agent, in form and substance acceptable to the Collateral Agent, such opinions of counsel and other documents as the Collateral
Agent shall request with respect thereto; provided, however, that no Grantor shall be required to pledge any Excluded Collateral.
Each Grantor hereby authorizes the Collateral Agent to attach such updated Schedules to this Agreement and agrees that all Pledged
Equity listed on any updated Schedule delivered to the Collateral Agent shall for all purposes hereunder be considered Collateral.
The Grantors agree that the pledge of the shares of Capital Stock acquired by a Grantor of Foreign Subsidiary may be supplemented
by one or more separate pledge agreements, deeds of pledge, share charges, or other similar agreements or instruments, executed
and delivered by the relevant Grantor in favor of the Collateral Agent, which pledge agreements will provide for the pledge of
such shares of Capital Stock in accordance with the laws of the applicable foreign jurisdiction. With respect to such shares of
Capital Stock, the Collateral Agent may, at any time and from time to time, in its sole discretion, take actions in such foreign
jurisdictions that will result in the perfection of the Lien created in such shares of Capital Stock.

 

Section
6. Additional Provisions Concerning the Collateral.

 

(a)
To the maximum extent permitted by applicable law, and for the purpose of taking any action that the Collateral Agent may deem
necessary or advisable to accomplish the purposes of this Agreement, each Grantor hereby (i) authorizes the Collateral Agent to
execute any such agreements, instruments or other documents in such Grantor’s name and to file such agreements, instruments
or other documents in such Grantor’s name and in any appropriate filing office, (ii) authorizes the Collateral Agent at
any time and from time to time to file, one or more financing or continuation statements, and amendments thereto, relating to
the Collateral (including, without limitation, any such financing statements that (A) describe the Collateral as “all assets”
or “all personal property” (or words of similar effect) or that describe or identify the Collateral by type or in
any other manner as the Collateral Agent may determine regardless of whether any particular asset of such Grantor falls within
the scope of Article 9 of the Code or whether any particular asset of such Grantor constitutes part of the Collateral, and (B)
contain any other information required by Part 5 of Article 9 of the Code for the sufficiency or filing office acceptance of any
financing statement, continuation statement or amendment, including, without limitation, whether such Grantor is an organization,
the type of organization and any organizational identification number issued to such Grantor) and (iii) ratifies such authorization
to the extent that the Collateral Agent has filed any such financing or continuation statements, or amendments thereto, prior
to the date hereof. A photocopy or other reproduction of this Agreement or any financing statement covering the Collateral or
any part thereof shall be sufficient as a financing statement where permitted by law.

 

    	 	22	 

    	 	 	 

    

 

(b)
After an Event of Default has occurred and for so long as such Event of Default is continuing, each Grantor hereby irrevocably
appoints the Collateral Agent as its attorney-in-fact and proxy, with full authority in the place and stead of such Grantor and
in the name of such Grantor or otherwise, from time to time in the Collateral Agent’s discretion, to take any action and
to execute any instrument which the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement,
including, without limitation, (i) to obtain and adjust insurance required to be paid to the Collateral Agent pursuant to Section
5(e) hereof, (ii) to ask, demand, collect, sue for, recover, compound, receive and give acquittance and receipts for moneys
due and to become due under or in respect of any Collateral, (iii) to receive, endorse, and collect any drafts or other instruments,
documents and chattel paper in connection with clause (i) or (ii) above, (iv) to file any claims or take any action or institute
any proceedings which the Collateral Agent may deem necessary or desirable for the collection of any Collateral or otherwise to
enforce the rights of the Collateral Agent and the Noteholders with respect to any Collateral, (v) to execute assignments, licenses
and other documents to enforce the rights of the Collateral Agent and the Noteholders with respect to any Collateral, and (vi)
to verify any and all information with respect to any and all Accounts. This power is coupled with an interest and is irrevocable
until all of the Obligations are Paid in Full.

 

(c)
For the purpose of enabling the Collateral Agent to exercise rights and remedies hereunder, at such time after an Event of Default
shall have occurred and be continuing as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies,
and for no other purpose, each Grantor hereby grants to the Collateral Agent, to the extent assignable, an irrevocable, non-exclusive
license (exercisable without payment of royalty or other compensation to any Grantor) to use, assign, license or sublicense any
Intellectual Property now owned or hereafter acquired by such Grantor, wherever the same may be located, including in such license
reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer programs used
for the compilation or printout thereof. Notwithstanding anything contained herein to the contrary, but subject to the provisions
of the Securities Purchase Agreement that limit the right of any Grantor to dispose of its property, and Section 5(g) and
Section 5(h) hereof, so long as no Event of Default shall have occurred and be continuing, any Grantor may exploit, use,
enjoy, protect, license, sublicense, assign, sell, dispose of or take other actions with respect to the Intellectual Property
in the ordinary course of its business and as expressly permitted by any of the other Transaction Documents. In furtherance of
the foregoing, unless an Event of Default shall have occurred and be continuing, the Collateral Agent shall from time to time,
upon the request of any Grantor, execute and deliver any instruments, certificates or other documents, in the form so requested,
which such Grantor shall have certified are appropriate (in such Grantor’s judgment) to allow it to take any action permitted
above (including relinquishment of the license provided pursuant to this clause (c) as to any Intellectual Property). Further,
upon the Payment in Full of all of the Obligations, the Collateral Agent (subject to Section 10(e) hereof) shall release
and reassign to any Grantor all of the Collateral Agent’s right, title and interest in and to the Intellectual Property,
and the Licenses, all without recourse, representation or warranty whatsoever. The exercise of rights and remedies hereunder by
the Collateral Agent shall not terminate the rights of the holders of any licenses or sublicenses theretofore granted by each
Grantor in accordance with the second sentence of this clause (c). Each Grantor hereby releases the Collateral Agent from any
claims, causes of action and demands at any time arising out of or with respect to any actions taken or omitted to be taken by
the Collateral Agent under the powers of attorney granted herein other than actions taken or omitted to be taken through the Collateral
Agent’s gross negligence or willful misconduct, as determined by a final determination of a court of competent jurisdiction.

 

    	 	23	 

    	 	 	 

    

 

(d)
If any Grantor fails to perform any agreement or obligation contained herein, the Collateral Agent may itself perform, or cause
performance of, such agreement or obligation, in the name of such Grantor or the Collateral Agent, and the reasonable expenses
of the Collateral Agent incurred in connection therewith shall be payable by such Grantor pursuant to Section 8 hereof
and shall be secured by the Collateral.

 

(e)
The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Collateral and shall not impose
any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting
for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral or as to the taking
of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

 

(f)
Anything herein to the contrary notwithstanding (i) each Grantor shall remain liable under the Licenses and otherwise with respect
to any of the Collateral to the extent set forth therein to perform all of its obligations thereunder to the same extent as if
this Agreement had not been executed, (ii) the exercise by the Collateral Agent of any of its rights hereunder shall not release
any Grantor from any of its obligations under the Licenses or otherwise in respect of the Collateral, and (iii) the Collateral
Agent shall not have any obligation or liability by reason of this Agreement under the Licenses or with respect to any of the
other Collateral, nor shall the Collateral Agent be obligated to perform any of the obligations or duties of any Grantor thereunder
or to take any action to collect or enforce any claim for payment assigned hereunder.

 

(g)
As long as no Event of Default shall have occurred and be continuing and until written notice shall be given to the applicable
Grantor:

 

(i)
Each Grantor shall have the right, from time to time, to vote and give consents with respect to the Pledged Equity, or any part
thereof for all purposes not inconsistent with the provisions of this Agreement, the Securities Purchase Agreement or any other
Transaction Document; provided, however, that no vote shall be cast, and no consent shall be given or action taken, which would
have the effect of impairing the position or interest of the Collateral Agent in respect of the Pledged Equity or which would
authorize, effect or consent to, to the extent expressly permitted by the Securities Purchase Agreement:

 

    	 	24	 

    	 	 	 

    

 

(A)
the dissolution or liquidation, in whole or in part, of a Pledged Entity;

 

(B)
the consolidation or merger of a Pledged Entity with any other Person;

 

(C)
the sale, disposition or encumbrance of all or substantially all of the assets of a Pledged Entity, except for Liens in favor
of the Collateral Agent;

 

(D)
any change in the authorized number of shares, the stated capital or the authorized share capital of a Pledged Entity or the issuance
of any additional shares of its Capital Stock; or

 

(E)
the alteration of the voting rights with respect to the Capital Stock of a Pledged Entity.

 

(h)
         (i) Each Grantor shall be entitled, from time to time, to collect and
receive for its own use all: (A) cash dividends and interest paid in respect of the Pledged Equity to the extent not in
violation of the Securities Purchase Agreement; and (B) (1) dividends and interest paid or payable other than in cash in
respect of any Pledged Equity, and instruments and other property received, receivable or otherwise distributed in respect
of, or in exchange for, any Pledged Equity, (2) dividends and other distributions paid or payable in cash in respect of any
Pledged Equity in connection with a partial or total liquidation or dissolution or in connection with a reduction of capital,
capital surplus or paid-in capital of a Pledged Entity, and (3) cash paid, payable or otherwise distributed, in respect of
principal of, or in redemption of, or in exchange for, any Pledged Equity; provided, however, that until actually paid all
rights to such distributions shall remain subject to the Lien created by this Agreement; and

 

(ii)
all dividends and interest (other than such cash dividends and interest as are permitted to be paid to any Grantor in accordance
with clause (i) above) and all other distributions in respect of any of the Pledged Equity, whenever paid or made, shall be delivered
to the Collateral Agent to hold as Pledged Equity and shall, if received by any Grantor, be received in trust for the benefit
of the Collateral Agent (for the benefit the Noteholders), be segregated from the other property or funds of such Grantor, and
be forthwith delivered to the Collateral Agent as Pledged Equity in the same form as so received (with any necessary endorsement).

SECTION
7. Remedies Upon Event of Default; Application of Proceeds. If any Event of Default shall have
occurred and be continuing:

 

(a)
The Collateral Agent may exercise in respect of the Collateral, in addition to any other rights and remedies provided for herein,
in any other Transaction Document or otherwise available to it, all of the rights and remedies of a secured party upon default
under the Code (whether or not the Code applies to the affected Collateral), and also may (i) take absolute control of the Collateral,
including, without limitation, transfer into the Collateral Agent’s name or into the name of its nominee or nominees (to
the extent the Collateral Agent has not theretofore done so) and thereafter receive, for the benefit of the Noteholders, all payments
made thereon, give all consents, waivers and ratifications in respect thereof and otherwise act with respect thereto as though
it were the outright owner thereof, (ii) require each Grantor to, and each Grantor hereby agrees that it will at its expense and
upon request of the Collateral Agent forthwith, assemble all or part of its respective Collateral as directed by the Collateral
Agent and make it available to the Collateral Agent at a place or places to be designated by the Collateral Agent that is reasonably
convenient to both parties, and the Collateral Agent may enter into and occupy any premises owned or leased by any Grantor where
the Collateral or any part thereof is located or assembled for a reasonable period in order to effectuate the Collateral Agent’s
rights and remedies hereunder or under law, without obligation to any Grantor in respect of such occupation, and (iii) without
advance notice except as specified below and without any obligation to prepare or process the Collateral for sale (provided that
the Collateral Agent shall give notice to any Grantor as promptly as practicable with respect to any such sale), (A) sell the
Collateral or any part thereof in one or more parcels at public or private sale (including, without limitation, by credit bid),
at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and at such price or
prices and upon such other terms as the Collateral Agent may deem commercially reasonable and/or (B) lease, license or dispose
of the Collateral or any part thereof upon such terms as the Collateral Agent may deem commercially reasonable. Each Grantor agrees
that, to the extent notice of sale or any other disposition of its respective Collateral shall be required by law, at least ten
(10) days’ notice to any Grantor of the time and place of any public sale or the time after which any private sale or other
disposition of its respective Collateral is to be made shall constitute reasonable notification. The Collateral Agent shall not
be obligated to make any sale or other disposition of any Collateral regardless of notice of sale having been given. The Collateral
Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such
sale may, without further notice, be made at the time and place to which it was so adjourned. Each Grantor hereby waives any claims
against the Collateral Agent and the Noteholders arising by reason of the fact that the price at which its respective Collateral
may have been sold at a private sale was less than the price which might have been obtained at a public sale or was less than
the aggregate amount of the Obligations, even if the Collateral Agent accepts the first offer received and does not offer such
Collateral to more than one offeree, and waives all rights that any Grantor may have to require that all or any part of such Collateral
be marshaled upon any sale (public or private) thereof. Each Grantor hereby acknowledges that (i) any such sale of its respective
Collateral by the Collateral Agent shall be made without warranty, (ii) the Collateral Agent may specifically disclaim any warranties
of title, possession, quiet enjoyment or the like, and (iii) such actions set forth in clauses (i) and (ii) above shall not adversely
affect the commercial reasonableness of any such sale of Collateral. In addition to the foregoing, (1) upon written notice to
any Grantor from the Collateral Agent after and during the continuance of an Event of Default, such Grantor shall cease any use
of the Intellectual Property or any trademark, patent or copyright similar thereto for any purpose described in such notice; (2)
the Collateral Agent may, at any time and from time to time after and during the continuance of an Event of Default, upon 10 days’
prior notice to such Grantor, license, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis,
any of the Intellectual Property, throughout the universe for such term or terms, on such conditions, and in such manner, as the
Collateral Agent shall in its sole discretion determine; and (3) the Collateral Agent may, at any time, pursuant to the authority
granted in Section 6 hereof or otherwise (such authority being effective upon the occurrence and during the continuance
of an Event of Default), execute and deliver on behalf of such Grantor, one or more instruments of assignment of the Intellectual
Property (or any application or registration thereof), in form suitable for filing, recording or registration in any country.

 

    	 	26	 

    	 	 	 

    

 

(b)
Any cash held by the Collateral Agent as Collateral and all Cash Proceeds received by the Collateral Agent in respect of any sale
or disposition of or collection from, or other realization upon, all or any part of the Collateral shall be applied as follows
(subject to the provisions of the Securities Purchase Agreement): first, to pay any fees, indemnities or expense reimbursements
then due to the Collateral Agent (including those described in Section 8 hereof); second, to pay any fees, indemnities
or expense reimbursements then due to the Noteholders, on a pro rata basis; third to pay interest due under the Notes owing
to the Noteholders, on a pro rata basis; fourth, to pay or prepay principal in respect of the Notes, whether or not then
due, owing to the Noteholders, on a pro rata basis; fifth, to pay or prepay any other Obligations, whether or not then
due, in such order and manner as the Collateral Agent shall elect, consistent with the provisions of the Securities Purchase Agreement.
Any surplus of such cash or Cash Proceeds held by the Collateral Agent and remaining after the Payment in Full of all of the Obligations
shall be paid over to the Company or as a court of competent jurisdiction may otherwise direct.

 

(c)
In the event that the proceeds of any such sale, disposition, collection or realization are insufficient to pay all amounts to
which the Collateral Agent and the Noteholders are legally entitled, each Grantor shall be, jointly and severally, liable for
the deficiency, together with interest thereon at the highest rate specified in the Notes for interest on overdue principal thereof
or such other rate as shall be fixed by applicable law, together with the costs of collection and the reasonable fees, costs,
expenses and other charges of any attorneys employed by the Collateral Agent to collect such deficiency.

 

(d)
To the extent that applicable law imposes duties on the Collateral Agent to exercise remedies in a commercially reasonable manner,
each Grantor acknowledges and agrees that it is commercially reasonable for the Collateral Agent (i) to fail to incur expenses
deemed significant by the Collateral Agent to prepare Collateral for disposition or otherwise to transform raw material or work
in process into finished goods or other finished products for disposition, (ii) to fail to obtain third party consents for access
to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party
consents for the collection or disposition of Collateral to be collected or disposed of, (iii) to fail to exercise collection
remedies against Account Debtors or other Persons obligated on Collateral or to remove Liens on or any adverse claims against
Collateral, (iv) to exercise collection remedies against Account Debtors and other Persons obligated on Collateral directly or
through the use of collection agencies and other collection specialists, (v) to advertise dispositions of Collateral through publications
or media of general circulation, whether or not the Collateral is of a specialized nature, (vi) to contact other Persons, whether
or not in the same business as any Grantor, for expressions of interest in acquiring all or any portion of such Collateral, (vii)
to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a
specialized nature, (viii) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the
types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets,
(ix) to dispose of assets in wholesale rather than retail markets, (x) to disclaim disposition warranties, such as title, possession
or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure the Collateral Agent against risks of loss, collection
or disposition of Collateral or to provide to the Collateral Agent a guaranteed return from the collection or disposition of Collateral,
or (xii) to the extent deemed appropriate by the Collateral Agent, to obtain the services of brokers, investment bankers, consultants,
attorneys and other professionals to assist the Collateral Agent in the collection or disposition of any of the Collateral. Each
Grantor acknowledges that the purpose of this section is to provide non-exhaustive indications of what actions or omissions by
the Collateral Agent would be commercially reasonable in the Collateral Agent’s exercise of remedies against the Collateral
and that other actions or omissions by the Collateral Agent shall not be deemed commercially unreasonable solely on account of
not being indicated in this section. Without limitation upon the foregoing, nothing contained in this section shall be construed
to grant any rights to any Grantor or to impose any duties on the Collateral Agent that would not have been granted or imposed
by this Agreement or by applicable law in the absence of this section.

 

    	 	27	 

    	 	 	 

    

 

(e)
The Collateral Agent shall not be required to marshal any present or future collateral security (including, but not limited to,
this Agreement and the Collateral) for, or other assurances of payment of, the Obligations or any of them or to resort to such
collateral security or other assurances of payment in any particular order, and all of the Collateral Agent’s rights hereunder
and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights,
however existing or arising. To the extent that any Grantor lawfully may, each Grantor hereby agrees that it will not invoke any
law relating to the marshaling of collateral which might cause delay in or impede the enforcement of the Collateral Agent’s
rights under this Agreement or under any other instrument creating or evidencing any of the Obligations or under which any of
the Obligations is outstanding or by which any of the Obligations is secured or payment thereof is otherwise assured, and, to
the extent that it lawfully may, each Grantor hereby irrevocably waives the benefits of all such laws.

 

Section
8. Indemnity and Expenses.

 

(a)
Each Grantor agrees, jointly and severally, to defend, protect, indemnify and hold the Collateral Agent and each of the Noteholders
harmless from and against any and all claims, damages, losses, liabilities, obligations, penalties, fees, costs and expenses (including,
without limitation, reasonable legal fees, costs, expenses, and disbursements of such Person’s counsel) to the extent that
they arise out of or otherwise result from this Agreement (including, without limitation, enforcement of this Agreement), except
to the extent resulting from such Person’s gross negligence or willful misconduct, as determined by a final judgment of
a court of competent jurisdiction no longer subject to appeal.

 

(b)
Each Grantor agrees, jointly and severally, to pay to the Collateral Agent upon demand the amount of any and all reasonable, out-of-pocket
costs and expenses, including the reasonable fees, costs, expenses and disbursements of counsel for the Collateral Agent and of
any experts and agents (including, without limitation, any collateral trustee which may act as agent of the Collateral Agent),
which the Collateral Agent may incur in connection with (i) the preparation, negotiation, execution, delivery, recordation, administration,
amendment, waiver or other modification or termination of this Agreement, (ii) the custody, preservation, use or operation of,
or the sale of, collection from, or other realization upon, any Collateral, (iii) the exercise or enforcement of any of the rights
of the Collateral Agent hereunder, or (iv) the failure by any Grantor to perform or observe any of the provisions hereof.

 

    	 	28	 

    	 	 	 

    

 

SECTION 9. Notices,
Etc. All notices and other communications provided for hereunder shall be in writing and shall be mailed (by certified
mail, first-class postage prepaid and return receipt requested), telecopied, e-mailed or delivered, if to any Grantor, to the
Company’s address, or if to the Collateral Agent or any Noteholder, to it at its respective address, each as set forth
in Section 9(f) of the Securities Purchase Agreement; or as to any such Person, at such other address as shall be designated
by such Person in a written notice to all other parties hereto complying as to delivery with the terms of this Section
9. All such notices and other communications shall be deemed to have been delivered: (i) upon receipt, when delivered
personally; (ii) with respect to notice sent by electronic mail (provided that such sent email is kept on file (whether
electronically or otherwise) by the sending party and the sending party does not receive an automatically generated message
from the recipient’s email server that such e-mail could not be delivered to such recipient) (A) if sent prior to 6:00
PM New York time on any Business Day, when sent, or (B) if sent on or after 6:00 PM New York time on any Trading Day (as
defined in the Securities Purchase Agreement), on the next Business Day; or (iii) one (1) Business Day after deposit with an
overnight courier service with next day delivery specified, in each case, properly addressed to the party to receive the
same. For the avoidance of doubt, all Foreign Subsidiaries, as Grantors, hereby appoint the Company as its agent for receipt
of service of process and all notices and other communications in the United States at the address specified
below.

 

Section
10. Miscellaneous.

 

(a)
No amendment of any provision of this Agreement shall be effective unless it is in writing and signed by each Grantor and the
Collateral Agent (and approved by the Required Holders), and no waiver of any provision of this Agreement, and no consent to any
departure by each Grantor therefrom, shall be effective unless it is in writing and signed by each Grantor and the Collateral
Agent (and approved by the Required Holders), and then such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given. No amendment, modification or waiver of this Agreement shall be effective to the
extent that it (1) applies to fewer than all of the holders of Notes or (2) imposes any obligation or liability on any holder
of Notes without such holder’s prior written consent (which may be granted or withheld in such holder’s sole discretion).

 

(b)
No failure on the part of the Collateral Agent to exercise, and no delay in exercising, any right reasonably hereunder or under
any of the other Transaction Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any such
right reasonably preclude any other or further exercise thereof or the exercise of any other right. The rights and remedies of
the Collateral Agent or any Noteholder provided herein and in the other Transaction Documents are cumulative and are in addition
to, and not exclusive of, any rights or remedies provided by law. The rights of the Collateral Agent or any Noteholder under any
of the other Transaction Documents against any party thereto are not conditional or contingent on any attempt by such Person to
exercise any of its rights under any of the other Transaction Documents against such party or against any other Person, including
but not limited to, any Grantor.

 

    	 	29	 

    	 	 	 

    

 

(c)
Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the remaining portions hereof or thereof or affecting
the validity or enforceability of such provision in any other jurisdiction.

 

(d)
This Agreement shall create a continuing security interest in the Collateral and shall (i) remain in full force and effect until
Payment in Full of the Obligations, and (ii) be binding on each Grantor and all other Persons who become bound as debtor to this
Agreement in accordance with Section 9-203(d) of the Code and shall inure, together with all rights and remedies of the Collateral
Agent and the Noteholders hereunder, to the benefit of the Collateral Agent and the Noteholders and their respective permitted
successors, transferees and assigns. Without limiting the generality of clause (ii) of the immediately preceding sentence, without
notice to any Grantor, the Collateral Agent and the Noteholders may assign or otherwise transfer their rights and obligations
under this Agreement and any of the other Transaction Documents, to any other Person and such other Person shall thereupon become
vested with all of the benefits in respect thereof granted to the Collateral Agent and the Noteholders herein or otherwise. Upon
any such assignment or transfer, all references in this Agreement to the Collateral Agent or any such Noteholder shall mean the
assignee of the Collateral Agent or such Noteholder. None of the rights or obligations of any Grantor hereunder may be assigned
or otherwise transferred without the prior written consent of the Collateral Agent, and any such assignment or transfer without
such consent of the Collateral Agent shall be null and void.

 

(e)
Upon the Payment in Full of the Obligations, (i) this Agreement and the security interests created hereby shall terminate and
all rights to the Collateral shall revert to the respective Grantor that granted such security interests hereunder, and (ii) the
Collateral Agent will, upon any Grantor’s request and at such Grantor’s expense, (A) return to such Grantor such of
the Collateral as shall not have been sold or otherwise disposed of or applied pursuant to the terms hereof and (B) execute and
deliver to such Grantor such documents as such Grantor shall reasonably request to evidence such termination, all without any
representation, warranty or recourse whatsoever.

 

(f)
Governing Law; Jurisdiction; Jury Trial.

 

(i)
All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the
internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether
of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than
the State of New York.

 

(ii)
Each Party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New
York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or under any of the other
Transaction Documents or with any transaction contemplated hereby or thereby, and hereby irrevocably waives, and agrees not to
assert in any suit, action or proceeding, any claim, defense or objection 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. Each party hereby irrevocably waives personal service of process and consents to process being served

collectively, the “Notes”);

 

WHEREAS,
it is a condition precedent to the purchase of the Notes under the Securities Purchase Agreement that each Grantor has executed

(i)
the Patents and Patent applications set forth in Schedule A hereto;

 

(ii)
the Trademark and service mark registrations and applications set forth in Schedule B hereto (provided that no security interest
shall be granted in United States intent-to-use trademark applications to the extent that, and solely during the period in which,
the grant of a security interest therein would impair the validity or enforceability of such intent-to-use trademark applications
under applicable federal law), together with the goodwill symbolized thereby;

 

(iii)
all Copyrights, whether registered or unregistered, now owned or hereafter acquired by such Grantor, including, without limitation,
the copyright registrations and applications and exclusive copyright licenses set forth in Schedule C hereto;

 

(iv)
all reissues, divisions, continuations, continuations-in-part, extensions, renewals and reexaminations of any of the foregoing,
all rights in the foregoing provided by international treaties or conventions, all rights corresponding thereto throughout the
world and all other rights of any kind whatsoever of such Grantor accruing thereunder or pertaining thereto;

 

(v)
any and all claims for damages and injunctive relief for past, present and future infringement, dilution, misappropriation, violation,
misuse or breach with respect to any of the foregoing, with the right, but not the obligation, to sue for and collect, or otherwise
recover, such damages; and

 

(vi)
any and all proceeds of, collateral for, income, royalties and other payments now or hereafter due and payable with respect to,
and supporting obligations relating to, any and all of the Collateral of or arising from any of the foregoing.

 

SECTION
2. Security for Obligations. The grant of a security interest in, the Collateral by each Grantor under this IP Security
Agreement secures the payment of all Obligations of such Grantor now or hereafter existing under or in respect of the Notes and
the Transaction Documents, whether direct or indirect, absolute or contingent, and whether for principal, reimbursement obligations,
interest, premiums, penalties, fees, indemnifications, contract causes of action, costs, expenses or otherwise.

(ii)
Each Party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New

Transaction Documents or with any transaction contemplated hereby or thereby, and hereby irrevocably waives, and agrees not to
assert in any suit, action or proceeding, any claim, defense or objection 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. Each party hereby irrevocably waives personal service of process and consents to process being served
in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under Section
9(f) of the Securities Purchase Agreement and agrees that such service shall constitute good and sufficient service of process
and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted

to enforce a judgment or other court ruling in favor of the Collateral Agent or a Noteholder.

 

(iii)

SECTION 2. Guaranty.

 

(a)
The Guarantors, jointly and severally, hereby unconditionally and irrevocably, guaranty to the Collateral Agent, for the benefit
of the Collateral Agent and the Buyers, the punctual payment, as and when due and payable, by stated maturity or otherwise, of
all Obligations, including, without limitation, all interest, make-whole and other amounts that accrue after the commencement
of any Insolvency Proceeding of the Company or any Guarantor, whether or not the payment of such interest, make-whole and/or other
amounts are enforceable or are allowable in such Insolvency Proceeding, and all fees, interest, premiums, penalties, causes of
actions, costs, commissions, expense reimbursements, indemnifications and all other amounts due or to become due under any of
the Transaction Documents (all of the foregoing collectively being the “Guaranteed Obligations”), and agrees
to pay any and all reasonable costs and expenses (including counsel fees and expenses) incurred by the Collateral Agent in enforcing
any rights under this Guaranty or any other Transaction Document. Without limiting the generality of the foregoing, each Guarantor’s
liability hereunder shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Company
to the Collateral Agent or any Buyer under the Securities Purchase Agreement and the Notes but for the fact that they are unenforceable
or not allowable due to the existence of an Insolvency Proceeding involving any Transaction Party.

 

(b)
Each Guarantor, and by its acceptance of this Guaranty, the Collateral Agent and each Buyer, hereby confirms that it is the intention
of all such Persons that this Guaranty and the Guaranteed Obligations of each Guarantor hereunder not constitute a fraudulent
transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer
Act or any similar foreign, federal, provincial, state, or other applicable law to the extent applicable to this Guaranty and
the Guaranteed Obligations of each Guarantor hereunder. To effectuate the foregoing intention, the Collateral Agent, the Buyers
and the Guarantors hereby irrevocably agree that the Guaranteed Obligations of each Guarantor under this Guaranty at any time
shall be limited to the maximum amount as will result in the Guaranteed Obligations of such Guarantor under this Guaranty not
constituting a fraudulent transfer or conveyance.

 

    	 	3	 

    	 

    

 

SECTION 3. Guaranty
Absolute; Continuing Guaranty; Assignments.

 

(a)
The Guarantors, jointly and severally, guaranty that the Guaranteed Obligations will be paid strictly in accordance with the terms
of the Transaction Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting
any of such terms or the rights of the Collateral Agent or any Buyer with respect thereto. The obligations of each Guarantor under
this Guaranty are independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against
any Guarantor to enforce such obligations, irrespective of whether any action is brought against any Transaction Party or whether
any Transaction Party is joined in any such action or actions. The liability of any Guarantor under this Guaranty shall be as
a primary obligor (and not merely as a surety) and shall be irrevocable, absolute and unconditional irrespective of, and each
Guarantor hereby irrevocably waives, to the extent permitted by law, any defenses it may now or hereafter have in any way relating
to, any or all of the following:

 

(i)
any lack of validity or enforceability of any Transaction Document;

 

(ii)
any change in the time, manner or place of payment of, or in any other term of, all or any of the Guaranteed Obligations, or any
other amendment or waiver of or any consent to departure from any Transaction Document, including, without limitation, any increase
in the Guaranteed Obligations resulting from the extension of additional credit to any Transaction Party or extension of the maturity
of any Guaranteed Obligations or otherwise;

 

(iii)
any taking, exchange, release or non-perfection of any Collateral;

 

(iv)
any taking, release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed
Obligations;

 

(v)
any change, restructuring or termination of the corporate, limited liability company or partnership structure or existence of
any Transaction Party;

 

(vi)
any manner of application of Collateral or any other collateral, or proceeds thereof, to all or any of the Guaranteed Obligations,
or any manner of sale or other disposition of any Collateral or any other collateral for all or any of the Guaranteed Obligations
or any other Obligations of any Transaction Party under the Transaction Documents or any other assets of any Transaction Party
or any of its Subsidiaries;

 

(vii)
any failure of the Collateral Agent or any Buyer to disclose to any Transaction Party any information relating to the business,
condition (financial or otherwise), operations, performance, properties or prospects of any other Transaction Party now or hereafter
known to the Collateral Agent or any Buyer (each Guarantor waiving any duty on the part of the Collateral Agent or any Buyer to
disclose such information);

 

(viii)
taking any action in furtherance of the release of any Guarantor or any other Person that is liable for the Obligations from all
or any part of any liability arising under or in connection with any Transaction Document without the prior written consent of
the Collateral Agent; or

 

    	 	4	 

    	 

    

 

(ix)
any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation
by the Collateral Agent or any Buyer that might otherwise constitute a defense available to, or a discharge of, any Transaction
Party or any other guarantor or surety.

 

(b)
This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed
Obligations is rescinded or must otherwise be returned by the Collateral Agent, any Buyer, or any other Person upon the insolvency,
bankruptcy or reorganization of any Transaction Party or otherwise, all as though such payment had not been made.

 

(c)
This Guaranty is a continuing guaranty and shall (i) remain in full force and effect until Payment in Full of the Guaranteed Obligations
(other than inchoate indemnity obligations) and shall not terminate for any reason prior to the respective Maturity Date of each
Note (other than Payment in Full of the Guaranteed Obligations) and (ii) be binding upon each Guarantor and its respective successors
and assigns. This Guaranty shall inure to the benefit of and be enforceable by the Collateral Agent, the Buyers, and their respective
successors, and permitted pledgees, transferees and assigns. Without limiting the generality of the foregoing sentence, the Collateral
Agent or any Buyer may pledge, assign or otherwise transfer all or any portion of its rights and obligations under and subject
to the terms of any Transaction Document to any other Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to the Collateral Agent or such Buyer (as applicable) herein or otherwise, in each case as
provided in the Securities Purchase Agreement or such Transaction Document.

 

SECTION 4. Waivers.
To the extent permitted by applicable law, each Guarantor hereby waives promptness, diligence, protest, notice of acceptance and
any other notice or formality of any kind with respect to any of the Guaranteed Obligations and this Guaranty and any requirement
that the Collateral Agent exhaust any right or take any action against any Transaction Party or any other Person or any Collateral.
Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated herein
and that the waiver set forth in this Section 4 is knowingly made in contemplation of such benefits. The Guarantors hereby
waive any right to revoke this Guaranty, and acknowledge that this Guaranty is continuing in nature and applies to all Guaranteed
Obligations, whether existing now or in the future. Without limiting the foregoing, to the extent permitted by applicable law,
each Guarantor hereby unconditionally and irrevocably waives (a) any defense arising by reason of any claim or defense based upon
an election of remedies by the Collateral Agent or any Buyer that in any manner impairs, reduces, releases or otherwise adversely
affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of such Guarantor or other rights
of such Guarantor to proceed against any of the other Transaction Parties, any other guarantor or any other Person or any Collateral,
and (b) any defense based on any right of set-off or counterclaim against or in respect of the Guaranteed Obligations of such
Guarantor hereunder. Each Guarantor hereby unconditionally and irrevocably waives any duty on the part of the Collateral Agent
or any Buyer to disclose to such Guarantor any matter, fact or thing relating to the business, condition (financial or otherwise),
operations, performance, properties or prospects of any other Transaction Party or any of its Subsidiaries now or hereafter known
by the Collateral Agent or a Buyer.

 

    	 	5	 

    	 

    

 

SECTION 5. Subrogation.
No Guarantor may exercise any rights that it may now or hereafter acquire against any Transaction Party or any other guarantor
that arise from the existence, payment, performance or enforcement of any Guarantor’s obligations under this Guaranty, including,
without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate
in any claim or remedy of the Collateral Agent or any Buyer against any Transaction Party or any other guarantor or any Collateral,
whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation,
the right to take or receive from any Transaction Party or any other guarantor, directly or indirectly, in cash or other property
or by set-off or in any other manner, payment or security solely on account of such claim, remedy or right, unless and until there
has been Payment in Full of the Guaranteed Obligations. If any amount shall be paid to a Guarantor in violation of the immediately
preceding sentence at any time prior to Payment in Full of the Guaranteed Obligations and all other amounts payable under this
Guaranty, such amount shall be held in trust for the benefit of the Collateral Agent and shall forthwith be paid to the Collateral
Agent to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether matured
or unmatured, in accordance with the terms of the Transaction Document, or to be held as Collateral for any Guaranteed Obligations
or other amounts payable under this Guaranty thereafter arising. If (a) any Guarantor shall make payment to the Collateral Agent
of all or any part of the Guaranteed Obligations, and (b) there has been Payment in Full of the Guaranteed Obligations, the Collateral
Agent will, at such Guarantor’s request and expense, execute and deliver to such Guarantor appropriate documents, without
recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest
in the Guaranteed Obligations resulting from such payment by such Guarantor.

to do business and is in good standing in each jurisdiction in which the character of the properties owned or leased by it or

bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, suretyship or similar laws and equitable principles
(regardless of whether enforcement is sought in equity or at law).

 

(v)
There is no pending or, to the best knowledge of such Guarantor, threatened action, suit or proceeding against such Guarantor

SECTION 7. Right
of Set-off. Upon the occurrence and during the continuance of any Event of Default, the Collateral Agent and any Buyer may,
and is hereby authorized to, at any time and from time to time, without notice to the Guarantors (any such notice being expressly
waived by each Guarantor) and to the fullest extent permitted by law, set-off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at any time owing by the Collateral Agent or any
Buyer to or for the credit or the account of any Guarantor against any and all obligations of the Guarantors now or hereafter
existing under this Guaranty or any other Transaction Document, irrespective of whether or not the Collateral Agent or any Buyer
shall have made any demand under this Guaranty or any other Transaction Document and although such obligations may be contingent
or unmatured. The Collateral Agent and each Buyer agrees to notify the relevant Guarantor promptly after any such set-off and
application made by the Collateral Agent or such Buyer, provided that the failure to give such notice shall not affect the validity
of such set-off and application. The rights of the Collateral Agent or any Buyer under this Section 7 are in addition to
other rights and remedies (including, without limitation, other rights of set-off) which the Collateral Agent or such Buyer may
have under this Guaranty or any other Transaction Document in law or otherwise.

 

Section

(a)
Notwithstanding any provision herein contained to the contrary, each Guarantor’s liability hereunder shall be limited to
an amount not to exceed as of any date of determination the greater of:

 

(i)
the amount of all Guaranteed Obligations, plus interest thereon at the applicable Interest Rate as specified in the Note; and

 

(ii)
the amount which could be claimed by the Collateral Agent from any Guarantor under this Guaranty without rendering such claim
voidable or avoidable under the Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent
Conveyance Act or similar statute or common law after taking into account, among other things, Guarantor’s right of contribution
and indemnification.

 

(b)
Each Guarantor agrees that the Guaranteed Obligations may at any time and from time to time exceed the amount of the liability
of such Guarantor hereunder without impairing the guaranty hereunder or affecting the rights and remedies of the Collateral Agent
or any Buyer hereunder or under applicable law.

 

(c)
No payment made by the Company, any Guarantor, any other guarantor or any other Person or received or collected by the Collateral
Agent or any other Buyer from the Company, any of the Guarantors, any other guarantor or any other Person by virtue of any action

the Guaranteed Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder
which shall, notwithstanding any such payment (other than any payment made by such Guarantor in respect of the Guaranteed Obligations
or any payment received or collected from such Guarantor in respect of the Guaranteed Obligations), remain liable for the Guaranteed
Obligations up to the maximum liability of such Guarantor hereunder until after all of the Guaranteed Obligations and all other
amounts payable under this Guaranty shall have been Paid in Full.

 

    	 	8	 

    	 

    

 

(d)
Upon any Guarantor ceasing to be a Significant Subsidiary (to the extent the circumstances as a result of which it ceases to be
a Significant Subsidiary are not prohibited by the terms of the Transaction Documents), such Guarantor shall be automatically
released from its obligations under this Guaranty. The Collateral Agent shall execute any documents reasonably requested by the
Company or any Guarantor to evidence the release of such Guarantor from its obligations hereunder, provided that Company or Guarantor,
as applicable, agrees to pay all reasonable costs and expenses of the Collateral Agent (including the reasonable and documented
fees and expenses of counsel for the Collateral Agent) in connection with such release and execution of such documents.

the sending party); or (iii) one (1) Business Day after deposit with an nationally recognized overnight courier service with next

provided for hereunder shall be sent, if to any Guarantor, to the Company’s address and/or facsimile number, or if to the
Collateral Agent or any Buyer, to it at its respective address and/or facsimile number, each as set forth in Section 9(f) of the
Securities Purchase Agreement

 

Section
10. Governing Law; Jurisdiction. All questions
concerning the construction, validity, enforcement and interpretation of this Guaranty shall be governed by the internal laws
of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State
of New York or any other jurisdictions) that would cause the application of the laws of any jurisdiction other than the State
of New York. Each Guarantor hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in
The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or under any
of the other Transaction Documents or with any transaction contemplated hereby or thereby, and hereby irrevocably waives, and
agrees not to assert in any suit, action or proceeding, any claim, obligation or defense 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. Each party hereby irrevocably waives personal service of process and consents
to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such
notices to it under Section 9(f) of the Securities Purchase Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process
in any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude the Collateral Agent or the Buyers
from bringing suit or taking other legal action against any Guarantor in any other jurisdiction to collect on a Guarantor’s
obligations or to enforce a judgment or other court ruling in favor of the Collateral Agent or a Buyer.

 

    	 	9	 

    	 

    

 

SECTION 11. WAIVER
OF JURY TRIAL, ETC. EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL
FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR UNDER ANY OTHER TRANSACTION DOCUMENT OR IN CONNECTION WITH OR ARISING OUT OF
THIS GUARANTY, ANY OTHER TRANSACTION DOCUMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY.

 

SECTION 12. Taxes.

 

(a)
All payments made by any Guarantor hereunder or under any other Transaction Document shall be made in accordance with the terms
of the respective Transaction Document and shall be made without set-off, counterclaim, withholding, deduction or other defense.
Without limiting the foregoing, all such payments shall be made free and clear of and without deduction or withholding for any
present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding
taxes imposed on the net income of the Collateral Agent or any Buyer by the jurisdiction in which the Collateral Agent or
such Buyer is organized or where it has its principal lending office (all such nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities, collectively or individually, “Taxes”). If any Guarantor shall be required
to deduct or to withhold any Taxes from or in respect of any amount payable hereunder or under any other Transaction Document:

 

(i)
the amount so payable shall be increased to the extent necessary so that after making all required deductions and withholdings
(including Taxes on amounts payable to the Collateral Agent or any Buyer pursuant to this sentence) the Collateral Agent or each
Buyer receives an amount equal to the sum it would have received had no such deduction or withholding been made,

 

(ii)
such Guarantor shall make such deduction or withholding,

 

(iii)
such Guarantor shall pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable
law, and

 

(iv)
as promptly as possible thereafter, such Guarantor shall send the Collateral Agent or each Buyer an official receipt (or, if an
official receipt is not available, such other documentation as shall be satisfactory to the Collateral Agent, as the case may
be) showing payment. In addition, each Guarantor agrees to pay any present or future stamp or documentary taxes or any other excise
or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery, registration
or enforcement of, or otherwise with respect to, this Guaranty or any other Transaction Document (collectively, “Other
Taxes”).

 

    	 	10	 

    	 

    

 

(b)
Each Guarantor hereby indemnifies and agrees to hold each Indemnified Party harmless from and against Taxes or Other Taxes (including,
without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 12) paid
by any Indemnified Party as a result of any payment made hereunder or from the execution, delivery, registration or enforcement
of, or otherwise with respect to, this Guaranty or any other Transaction Document, and any liability (including penalties, interest
and expenses for nonpayment, late payment or otherwise) arising therefrom or with respect thereto, whether or not such Taxes or
Other Taxes were correctly or legally asserted. This indemnification shall be paid within thirty (30) days from the date on which
the Collateral Agent or such Buyer makes written demand therefor, which demand shall identify the nature and amount of such Taxes
or Other Taxes.

 

(c)
If any Guarantor fails to perform any of its obligations under this Section 12, such Guarantor shall indemnify the Collateral
Agent and each Buyer for any taxes, interest or penalties that may become payable as a result of any such failure. The obligations
of the Guarantors under this Section 12 shall survive the termination of this Guaranty and the payment of the Obligations
and all other amounts payable hereunder.

 

Section
13. Indemnification.

 

(a)
Without limitation of any other obligations of any Guarantor or remedies of the Collateral Agent or the Buyers under this Guaranty
or applicable law, except to the extent resulting from any Indemnified Party’s gross negligence or willful misconduct, as
determined by a final judgment of a court of competent jurisdiction no longer subject to appeal, each Guarantor shall, to the
fullest extent permitted by law, indemnify, defend and save and hold harmless the Collateral Agent and each Buyer and each of
their affiliates and their respective officers, directors, employees, agents and advisors (each, an “Indemnified Party”)
from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation,
reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party in connection
with or as a result of any failure of any Guaranteed Obligations to be the legal, valid and binding obligations of any Transaction
Party enforceable against such Transaction Party in accordance with their terms.

 

(b)
Each Guarantor hereby also agrees that none of the Indemnified Parties shall have any liability (whether direct or indirect, in
contract, tort or otherwise) or any fiduciary duty or obligation to any of the Guarantors or any of their respective affiliates
or any of their respective officers, directors, employees, agents and advisors, and each Guarantor hereby agrees not to assert
any claim against any Indemnified Party on any theory of liability, for special, indirect, consequential, incidental or punitive
damages arising out of or otherwise relating to the facilities, the actual or proposed use of the proceeds of the advances, the
Transaction Documents or any of the transactions contemplated by the Transaction Documents.

 

    	 	11	 

    	 

    

 

SECTION 14. Miscellaneous.

 

(a)
Each Guarantor will make each payment hereunder in lawful money of the United States of America and in immediately available funds
to the Collateral Agent or each Buyer, at such address specified by the Collateral Agent or such Buyer from time to time by notice
to the Guarantors.

 

(b)
No amendment or waiver of any provision of this Guaranty and no consent to any departure by any Guarantor therefrom shall in any
event be effective unless the same shall be in writing and signed by each Guarantor, the Collateral Agent and each Buyer, and
then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

 

(c)
No failure on the part of the Collateral Agent or any Buyer to exercise, and no delay in exercising, any right or remedy hereunder
or under any other Transaction Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right
hereunder or under any Transaction Document preclude any other or further exercise thereof or the exercise of any other right
or remedy. The rights and remedies of the Collateral Agent and the Buyers provided herein and in the other Transaction Documents
are cumulative and are in addition to, and not exclusive of, any rights or remedies provided by law. The rights and remedies of
the Collateral Agent and the Buyers under any Transaction Document against any party thereto are not conditional or contingent
on any attempt by the Collateral Agent or any Buyer to exercise any of their respective rights or remedies under any other Transaction
Document against such party or against any other Person.

 

(d)
Any provision of this Guaranty that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the remaining portions hereof or affecting the validity
or enforceability of such provision in any other jurisdiction.

 

(e)
This Guaranty is a continuing guaranty and shall (i) remain in full force and effect until Payment in Full of the Guaranteed Obligations
(other than inchoate indemnity obligations) and shall not terminate for any reason prior to the respective Maturity Date of each
Note (other than Payment in Full of the Guaranteed Obligations) and (ii) be binding upon each Guarantor and its respective successors
and assigns. This Guaranty shall inure, together with all rights and remedies of the Collateral Agent hereunder, to the benefit
of and be enforceable by the Collateral Agent, the Buyers, and their respective successors, and permitted pledgees, transferees
and assigns. Without limiting the generality of the foregoing sentence, the Collateral Agent or any Buyer may pledge, assign or
otherwise transfer all or any portion of its rights and obligations under and subject to the terms of the Securities Purchase
Agreement or any other Transaction Document to any other Person in accordance with the terms thereof, and such other Person shall
thereupon become vested with all the benefits in respect thereof granted to the Collateral Agent or such Buyer (as applicable)
herein or otherwise, in each case as provided in the Securities Purchase Agreement or such Transaction Document. None of the rights
or obligations of any Guarantor hereunder may be assigned or otherwise transferred without the prior written consent of each Buyer.

 

(f)
This Guaranty and the other Transaction Documents reflect the entire understanding of the transaction contemplated hereby and
shall not be contradicted or qualified by any other agreement, oral or written, entered into before the date hereof.

(g)
Section headings herein are included for convenience of reference only and shall not constitute a part of this Guaranty for any
other purpose.

 

Section
15. Currency Indemnity.

 

If,
for the purpose of obtaining or enforcing judgment against Guarantor in any court in any jurisdiction, it becomes necessary to
convert into any other currency (such other currency being hereinafter in this Section 15 referred to as the “Judgment
Currency”) an amount due under this Guaranty in any currency (the “Obligation Currency”) other than
the Judgment Currency, the conversion shall be made at the rate of exchange prevailing on the Business Day immediately preceding
(a) the date of actual payment of the amount due, in the case of any proceeding in the courts of courts of the jurisdiction that
will give effect to such conversion being made on such date, or (b) the date on which the judgment is given, in the case of any
proceeding in the courts of any other jurisdiction (the applicable date as of which such conversion is made pursuant to this Section
15 being hereinafter in this Section 15 referred to as the “Judgment Conversion Date”).

 

If,
in the case of any proceeding in the court of any jurisdiction referred to in the preceding paragraph, there is a change in the
rate of exchange prevailing between the Judgment Conversion Date and the date of actual receipt of the amount due in immediately
available funds, the Guarantors shall pay such additional amount (if any, but in any event not a lesser amount) as may be necessary
to ensure that the amount actually received in the Judgment Currency, when converted at the rate of exchange prevailing on the
date of payment, will produce the amount of the Obligation Currency which could have been purchased with the amount of’
the Judgment Currency stipulated in the judgment or judicial order at the rate of exchange prevailing on the Judgment Conversion
Date. Any amount due from the Guarantors under this Section 15 shall be due as a separate debt and shall not be affected
by judgment being obtained for any other amounts due under or in respect of this Guaranty.
