GUARANTEE


 


Section 3.01. Guarantee. Parent hereby unconditionally guarantees
to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of
the validity and enforceability of the Indenture, this Supplemental Indenture, the Notes or the obligations of the Company hereunder or
thereunder, that:


 


(a)    
the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid
interest on, each of the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption, conversion or
otherwise, and interest on the overdue principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable)
of and accrued and unpaid interest on, each of the Notes, if lawful, and all other obligations of the Company to the Holder or the Trustee
under the Indenture, this Supplemental Indenture and the Notes will be promptly paid or performed in full when due, whether at maturity,
by acceleration, redemption, conversion or otherwise; and


(b)   
in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly
paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration
or otherwise (collectively, such guarantee, the “Note Guarantee”).


 






     


     


    

 


Failing payment when due of any amount so guaranteed
or any performance so guaranteed for whatever reason, Parent will be obligated to pay or perform the same immediately. Parent agrees that
this is a guarantee of payment and not a guarantee of collection.


 


Parent hereby agrees that its obligations hereunder
are unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action
to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment
against the Company, any action to enforce the same or any other circumstance that might otherwise constitute a legal or equitable discharge
or defense of a guarantor. Parent hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event
of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands
whatsoever and covenants that this Note Guarantee will not be discharged except by complete performance of the obligations contained in
the Notes or the Indenture.


 


If any Holder or the Trustee is required by any
court or otherwise to return to the Company, Parent or any custodian, trustee, liquidator or other similar official acting in relation
to either the Company or the Guarantor, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore
discharged, will be reinstated in full force and effect.


 


Parent agrees that it will not be entitled to any
right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. Parent further agrees that, as between Parent, on the one hand, and the Holders and the Trustee, on the other hand,
(1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section 6.02 of the Indenture for the purposes
of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Section 6.02 of the Indenture,
such obligations (whether or not due and payable) will forthwith become due and payable by Parent for the purpose of this Note Guarantee.


 


Section 3.02 Limitation on Parent Liability. Parent, and by
its acceptance of this Note Guarantee, each Holder, hereby confirms that it is the intention of all such parties that this Note Guarantee
of Parent not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to this Note Guarantee.


 


Section 3.03 Execution. To evidence the Note Guarantee set forth
in Section 3.01 hereof, this Supplemental Indenture will be executed on behalf of Parent by one of its Officers. Parent hereby agrees
that the Note Guarantee set forth in Section 3.01 hereof will remain in full force and effect notwithstanding any failure to endorse on
each Note a notation of the Note Guarantee. If an Officer whose signature is on this Supplemental Indenture no longer holds that office
at the time the Trustee authenticates the Note on which the Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.
The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee
set forth in this Supplemental Indenture on behalf of Parent.


 


Section 3.04 Releases. Upon the satisfaction and discharge of
the Indenture in accordance with Article 3 of the Indenture, Parent will be released and relieved of any obligations under the Note Guarantee.


ARTICLE 4


 


NO RELEASE OF COMPANY 


 


Section 4.01. Obligations of the Company. Notwithstanding the
agreement of Parent to become liable for the due and punctual payment of the principal of (and premium, if any, on) and interest, if any
(including accrued and unpaid interest, if any), on all the Notes issued under and subject to the Indenture and for the delivery of Parent
Class A Common Stock and/or Cash upon conversion of the Notes pursuant to Article Fourteen of the Indenture, the Company remains fully
liable for all of its obligations under the Indenture and has not been released from any liabilities or obligations thereunder except
for the issuance of the Class A Common Stock of the Company upon conversion of the Notes pursuant to Article Fourteen of the Indenture.
