including, without limitation, all interest, make-whole and other amounts that accrue after the commencement of any Insolvency Proceeding

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);


 






    4


     


    

 


(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


 


(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.

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.

deduct or to withhold any Taxes from or in respect of any amount payable hereunder or under any other Transaction

(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

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”).


 


(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

or applicable law, except to the extent resulting from such 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.

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.
