SECTION
5.Covenants of the Grantor.
Until this Agreement has terminated in accordance with the terms hereof, the Grantor agrees to do the following:


 


(a)The
Grantor shall give prompt written notice to the Secured Party (and in any event not later than ten (10) days following any change
described below in this subsection) of: (i) any change in the Grantor’s name; (ii) any changes in the Grantor’s identity
or structure in any manner which might make any financing statement filed hereunder incorrect or misleading; or (iii) any
change in jurisdiction of organization; provided that the Grantor shall not locate any Collateral outside of the United
States nor shall the Grantor change its jurisdiction of organization to a jurisdiction outside of the United States.


 


(b)The

SECTION
7.Authorization; Secured Party Appointed Attorney-in-Fact.
The Secured Party shall have the right, to, in the name of the Grantor, or in the name of the Secured Party or otherwise, upon
notice to, but without the requirement of assent by the Grantor, and the Grantor hereby constitutes and appoints the Secured Party
(and any employees or agents designated by a Secured Party) as the Grantor’s true and lawful attorney-in-fact, with full

execute any and all such other documents and instruments, and do any and all acts and things for and on behalf of the Grantor,
that such Secured Party may deem necessary or advisable to maintain, protect, realize upon and preserve the Collateral and the
Secured Party’s security interests therein and to accomplish the purposes of this Agreement. The Secured Party agrees that,
except upon and during the continuance of an Event of Default, it shall not exercise the power of attorney, or any rights granted
to the Secured Party under this Section 7. The foregoing power of attorney is coupled with an interest and is irrevocable so long
as the Obligations have not been indefeasibly paid and performed in full and the commitments not terminated. The Grantor hereby
ratifies, to the extent permitted by law, all that the Secured Party shall lawfully and in good faith do or cause to be done by
virtue of and in compliance with this Section 7.


 


SECTION
8.Remedies.


 


(a)Upon
the occurrence and during the continuance of an Event of Default, the Secured Party shall have, in addition to all other rights
and remedies granted to the Secured Party in this Agreement or the Notes, all rights and remedies of a secured party under the
UCC and other applicable laws. Without limiting the generality of the foregoing, upon the occurrence and during the continuance
of an Event of Default, the Secured Party may sell, resell, lease, use, assign, license, sublicense, transfer or otherwise dispose
of any or all of the Collateral in its then condition or following any commercially reasonable preparation or processing (utilizing
in connection therewith any of Grantor’s assets, without charge or liability to any Secured Party therefor) at public or
private sale, by one or more contracts, in one or more parcels, at the same or different times, for cash or credit, or for future
delivery without assumption of any credit risk, all as the Secured Party deem advisable; provided, however, that the Grantor shall
be credited with the net proceeds of sale only when such proceeds are finally collected by the Secured Party. Each Secured Party
shall have the right upon any such public sale, and, to the extent permitted by law, upon any such private sale, to purchase the
whole or any part of the Collateral so sold, free of any right or equity of redemption, which right or equity of redemption the
Grantor hereby releases, to the extent permitted by law. The Grantor hereby agrees that the sending of notice by ordinary mail,
postage prepaid, to the address of the Grantor set forth herein or subsequent address that the Grantor provides to the Secured
Party in writing, of the place and time of any public sale or of the time after which any private sale or other intended disposition
is to be made, shall be deemed reasonable notice thereof if such notice is sent ten (10) business days prior to the date of such
sale or other disposition or the date on or after which such sale or other disposition may occur.


 



    	5



    	 



    



(b)The
cash proceeds actually received from the sale or other disposition or collection of the Collateral, and any other amounts received
in respect of the Collateral the application of which is not otherwise provided for herein shall be applied first, to the
payment of the reasonable costs and expenses of the Secured Party in exercising or enforcing their rights hereunder and in collecting
or attempting to collect any of the Collateral, and to the payment of all other amounts payable to the Secured Party pursuant to
Section 12 hereof; and second, to the payment of the Obligations. Any surplus thereof that exists after payment and performance
in full of the Obligations shall be promptly paid over to the Grantor or otherwise disposed of in accordance with the UCC or other
applicable law. The Grantor shall remain liable to the Secured Party for any deficiency that exists after any sale or other disposition
or collection of the Collateral.


 


SECTION
9.Certain Waivers.



 


(a)The
Grantor waives, to the fullest extent permitted by law: (i) any right of redemption with respect to the Collateral, whether
before or after sale hereunder, and all rights, if any, of marshalling of the Collateral or other collateral or security for the
Obligations; (ii) any right to require the Secured Party to: (A) proceed against any Person, (B) exhaust any other
collateral or security for any of the Obligations, (C) pursue any remedy in the Secured Party’s power or (D) except
as provided herein or in any of the Notes, make or give any presentments, demands for performance, notices of nonperformance, protests,
notices of protests or notices of dishonor in connection with any of the Collateral; and (iii) all claims, damages and demands
against the Secured Party arising out of the repossession, retention, sale or application of the proceeds of any sale of the Collateral.
