generally (after giving effect to the right of contribution established in Section 2(b)).
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | Each Guarantor agrees that the Obligations may at any time and from time to time exceed the amount of the liability of such Guarantor hereunder without impairing the guarantee
contained in this Section 2 or affecting the rights and remedies of the Purchasers hereunder.
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | The guarantee contained in this Section 2 shall remain in full force and effect until all the Obligations and the obligations of each Guarantor under the guarantee contained in

Each Guarantor's right of contribution shall be subject to the terms and conditions of Section 2(c). The provisions of this Section 2(b) shall in no respect limit the obligations and liabilities of any Guarantor to the Purchasers, and each

reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Purchasers by the Company on account of the Obligations are paid in full. If any amount shall be paid to

respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Purchasers, and the Purchase Agreement and the other Transaction Documents and
any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Purchasers may deem advisable from time to time, and any collateral security, guarantee or right of
offset at any time held by the Purchasers for the



6



---

payment of the Obligations may be sold, exchanged, waived, surrendered or released. The Purchasers shall have no obligation to protect, secure, perfect or
insure any Lien at any time held by them as security for the Obligations or for the guarantee contained in this Section 2 or any property subject thereto.

(e) Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of (i) the creation, renewal, extension or
accrual of any of the Obligations, (ii) the execution and delivery of this Guarantee or any Transaction Document, (iii) the performance or non-performance of the Obligations under any Transaction Document, (iv) any change in or
making, repayment or remaking or remaking of any loan, advance or other extension of credit at any time under this Guarantee or any other Transaction Document, (v) any Material Adverse Effect with respect to the Company, any Obligor or any

incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 2; and all dealings between the Company and any of the Guarantors, on the one hand, and the Purchasers, on the other hand, likewise
shall be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in this Section 2. Each Guarantor waives to the extent permitted by law acceptance, diligence, presentment, protest, demand for payment,
dishonor and notice of default or nonpayment to or upon the Company or any of the Guarantors with respect to the Obligations and notice of any of the foregoing. Each Guarantor understands and agrees that the guarantee contained in this
Section 2 shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the validity, legality, non-binding effect or enforceability of the Purchase Agreement or any other Transaction Document,
any of the Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by the Purchasers, (b) any defense, set-off or counterclaim (other than a defense of
payment or

performance or fraud or misconduct by Purchasers) which may at any time be available to or be asserted by the Company or any other Person against the

Obligations, or of such Guarantor under the guarantee contained in this Section 2, in bankruptcy or in any other instance. When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against any Guarantor, the
Purchasers may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as they may have against the Company, any other Guarantor or any other Person or against any collateral security or guarantee
for the Obligations or any right of offset with respect thereto, and any failure by the Purchasers to make any such demand, to pursue such other rights or remedies or to collect any payments from the Company, any other Guarantor or any other Person
or to realize upon any such collateral security or guarantee or to exercise any such right of offset, or any release of the Company, any other Guarantor or any other Person or any such collateral security, guarantee or right of offset, shall not
relieve any Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Purchasers against any Guarantor. For the purposes hereof,
demand shall include the commencement and continuance of any legal proceedings.

(f) Reinstatement. The
guarantee contained in this Section 2 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the
Purchasers upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the
Company or any Guarantor or any substantial part of its property, or otherwise, all as though such payments had not been made, provided that the Guarantor's rights of contribution pursuant to Section 2(b) above shall similarly
continue to be effective or be reinstated, as the case may be.

(g) Payments. Each Guarantor hereby guarantees that
payments hereunder will be paid to the Purchasers without set-off or counterclaim in U.S. dollars at the address set forth or referred to in the Purchase Agreement.

power and authority to own and use its properties and assets and to carry on its business as currently conducted. The Guarantor has no subsidiaries other
than those identified as such on the Disclosure Schedules to the Purchase Agreement. The Guarantor is duly qualified to do business and is in good standing as a foreign corporation in each jurisdiction in which the nature of the business conducted
or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, could not, individually or in the aggregate, (x) adversely affect the legality, validity or
enforceability of any of this Guaranty in any material respect, (y) have a material adverse effect on the results of operations, assets, or financial condition of the Company and the Guarantors taken as a whole or (z) adversely impair in
any material respect the Guarantor's ability to perform fully on a timely basis its obligations under this Guaranty (a Material Adverse Effect).

(b) Authorization; Enforcement. The Guarantor has the requisite corporate or other entity power and authority to enter into and to
consummate the transactions contemplated by this Guaranty, and otherwise to carry out its obligations hereunder. The execution and delivery of this Guaranty by the Guarantor and the consummation by it of the transactions contemplated hereby have
been duly authorized by all requisite corporate action on the part of the Guarantor. This Guaranty has been duly executed and delivered by the Guarantor and constitutes the valid and binding obligation of the Guarantor enforceable against the
Guarantor in accordance with its terms, except (i) as may be limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium, affecting enforcement of, creditors rights generally, (ii) as
limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies, (iii) insofar as indemnification and contribution provisions may be limited by applicable law, and (iv) insofar as certain
elections, waivers and agreements to vary statutory provisions may be impermissible under the UCC (as defined in the Security Agreement) and other applicable law (clauses (i) through (iv) may be referred to collectively as the
Enforceability Limits).

(c) No Conflicts. The execution, delivery and performance of this
Guaranty by the Guarantor and the consummation by the Guarantor of the transactions contemplated thereby do not and will not (i) violate any provision of its Organizational Documents (as defined in the Security Agreement) or
(ii) constitute a default (or an event which with notice or lapse of time or both would become a default) in any material respect under, or give to others any commercially reasonable right of termination, material amendment, acceleration or
cancellation of, any agreement, indenture or instrument to which the Guarantor is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental
authority to which the Guarantor is subject (including Federal and state securities laws and regulations), or by which any material property or asset of the Guarantor is bound or affected, except in the case of each of clauses (ii) and (iii),
such conflicts,

defaults, terminations, amendments, accelerations, cancellations and violations as could not, individually or in the aggregate, have or result in a Material
Adverse Effect. The business of the Guarantor is not being conducted in violation of any law, ordinance or regulation of any governmental authority, except for violations which, individually or in the aggregate, do not have a Material Adverse
Effect.

(d) Consents and Approvals. The Guarantor is not required to obtain any authorization, approval or other
action by, and no notice to or filing with, any governmental authority or regulatory body is required, no consent of any other third parties is required, and no other action on the party of the Guarantor is required in connection with the execution,
delivery and performance by the Guarantor of this Guaranty.

(e) Purchase Agreement. The representations and
warranties of the Company set forth in the Purchase Agreement as they relate to such Guarantor, each of which is hereby incorporated herein by reference, are true and correct as of each time such representations are deemed to be made pursuant to
such Purchase Agreement, and the Purchasers shall be entitled to rely on each of them as if they were fully set forth herein, provided, that each reference in each such representation and warranty to the Company's knowledge shall, for the purposes
of this Section 3, be deemed to be a reference to such Guarantor's knowledge.

4. Covenants.

(a) Each Guarantor covenants and agrees with the Purchasers that, from and after the date of this Guarantee until the Obligations shall
have been paid in full, such Guarantor shall take, and/or shall refrain from taking, as the case may be, each commercially reasonable action that is necessary to be taken or not taken, as the case may be, so that no Event of Default is caused by the
failure to take such action or to refrain from taking such action by such Guarantor.

(b) So long as any of the Obligations
are outstanding, unless Purchasers holding at least 51% of the aggregate principal amount of the then outstanding Debentures, shall otherwise consent in writing, and except as any such action or non action may be permitted by the Purchase Agreement,
Debenture, or Security Agreement, each Guarantor will not directly or indirectly on or after the date of this Guarantee:

approval); or

vii. enter into any agreement with respect to any of the foregoing.

5. Miscellaneous.

(a) Amendments in Writing. This Guarantee may not be supplemented, modified, amended, restated, waived, extended, discharged or terminated orally. This Agreement may only be (i) supplemented, modified, amended or restated in a
writing signed by the Guarantors and Purchasers (or consented to in a separate writing by the Purchasers if they elect not to sign such document) and (ii) waived, extended, discharged or terminated in a writing signed by the party or parties
against whom such waiver, extension, discharge or termination would have to be enforced. By accepting this Agreement, whether or not a signatory hereto, each Purchaser acknowledges and agrees that the Purchaser is a party and one of the
parties for the purposes of this Guarantee and (A) is contractually bound by the provisions hereof applicable to it as such a party or one of the parties.

provided for in the Purchase Agreement, provided that any such notice, request or demand to or upon any Guarantor shall be addressed to such Guarantor at its notice address set forth on Schedule 5(b).

(c) No Waiver By Course Of Conduct; Cumulative Remedies. The Purchasers shall not by any act (except by a written instrument
pursuant to Section 5(a)), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any default under the Transaction Documents or Event of Default. No failure to exercise, nor any
delay



11



---

in exercising, on the part of any of the parties, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Purchasers of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy which the Purchasers would otherwise have on any future occasion. The rights and remedies of the parties herein provided are cumulative and not alternatives, may be exercised singly or concurrently and are
not exclusive of any other rights or remedies provided by law.

(d) Enforcement Expenses; Indemnification.

this Guarantee, the Debentures, the Security Agreement and the Purchase Agreement that apply to the Purchasers, Secured Parties and the Holders hereunder and thereunder.

(f) Set-Off. Each Guarantor hereby irrevocably authorizes the Purchasers at any time and from time to time while an Event of
Default under any of the Transaction Documents shall have occurred and is continuing without being waived by the Holder or cured by the Company, without notice to such Guarantor or any other Guarantor, any such notice being expressly waived by each
Guarantor, to set-off and appropriate and apply any and all deposits, credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by the
Purchasers to or for the credit or the account of such Guarantor, or any part thereof in such amounts as the Purchasers may elect, against and on account of the obligations and liabilities of such Guarantor to the Purchasers hereunder and claims of
every nature and description of the Purchasers against such Guarantor, in any currency, whether arising hereunder, under the Purchase Agreement, any other Transaction Document or otherwise, as the Purchasers may elect, whether or not the Purchasers
have made any demand for payment and although such obligations, liabilities and claims may be contingent or unmatured. The Purchasers shall notify such Guarantor promptly of any such set-off and the application made by the Purchasers of the proceeds
thereof, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Purchasers under this Section are in addition to other rights and remedies (including, without limitation, other
rights of set-off) which the Purchasers may have.

(g) Counterparts. This Guarantee may be executed in one or more
counterparts of the entire document or of the signature pages hereto, any of which may be delivered by telecopy, email or other electronic means, and each of which



13



---

when so executed shall be deemed to be an original, and all which when taken together shall constitute one and the same Guarantee. In the event that any
signature is delivered by facsimile transmission, e-mail, .pdf or similar format data file or other electronic means, such signature shall create a valid binding obligation of the party executing (or on whose behalf such signature is executed) the
same with the same force and effect as if such facsimile, .pdf or electronically transmitted signature page were an original thereof.

(h) Severability. If any term, provision, covenant or restriction of this Guarantee is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms,
provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, in each case unless the absence of the invalid, illegal, void or unenforceable term, provision,
covenant or restriction would impair the practical realization of the applicable party's principal rights and benefits hereunder, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable, in each case unless it absence of the invalid, illegal, void or unenforceable term, provision, covenant or
restriction would impair the practical realization of the applicable party's principal rights and benefits hereunder.

(i)
Section Headings. The Section headings used in this Guarantee are for convenience, only, do not constitute part of this Guarantee, and shall not be deemed to limit or affect any of the provisions hereof.

(j) Integration. This Guarantee is the Guarantee referred to in the Purchase Agreement and other Transaction Documents. All of the
applicable provisions of the Purchase Agreement and other Transaction Documents. All of the applicable provisions of the Purchase Agreement, including (without limitation) any provision for limiting the maximum rate of interest payable hereunder,
are incorporated herein by reference and made a part hereof. In the event that any specific provision of this Guarantee conflicts or is inconsistent with any specific term or provision contained in the Purchase Agreement shall control and be given
effect. However, this Guarantee contains provisions that are in addition to those contained in the Purchase Agreement, which each are cumulative with and not alternatives to each other, and which shall not be deemed or constructed to be in conflict
or inconsistent with the Purchase Agreement because they are not contained in it.

(k) Entire Understanding. No party
has (directly or indirectly) offered, made, accepted or acknowledged any representation, warranty, promise,



14



---

assurance or other agreement or understanding (whether written, oral, express, implied or otherwise) to, with or for the benefit of any other party any of
their respective Affiliates or representatives respecting any of the matters contained in this Guarantee except for those expressly set forth in this Guarantee. This Guarantee, together with the exhibits and schedules hereto, contain the entire
understanding of the parties with respect to the subject matter hereof and supersede all prior representations, warranties, promises, assurances and other agreements and understandings (whether written, oral, express, implied or otherwise) with
respect to such matters, which the parties acknowledge have been merged into this Agreement and its exhibits and schedules.

(l) Governing Law. THIS GUARANTEE SHALL BE, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, AND THE FEDERAL LAWS OF THE
UNITED STATES OF AMERICA, WITHOUT REGARD TO ANY PRINCIPLES OF CONFLICTS OF LAW THEREOF THAT WOULD DEFER TO THE SUBSTANTIVE LAWS OF ANY OTHER JURISDICTION.

party hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York, Borough of Manhattan. Each Debtor
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 with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such proceeding is improper.;
