 5. Authorized Action by Escrow Agent. Company hereby irrevocably appoints the Escrow Agent as its
attorney-in-fact (which appointment is coupled with an interest) and agrees that such Escrow Agent may perform (but the Escrow Agent shall not be obligated to and shall incur no liability to Company or any third party for failure so to do) any act
which Company is obligated by this Security Agreement to perform, and to exercise such rights and powers as Company might exercise with respect to the Collateral, including the right to (a) gain access to the books of Company pertaining to the
Collateral and to NWI’s premises at all reasonable times to inspect, make copies of and audit such books of NWI ; (b) collect by legal proceedings or otherwise and endorse, receive and receipt for all dividends, interest, payments,

sentence one time during any six consecutive month period, and (b) unless an Event of Default shall have occurred, the Escrow Agent shall bear all costs and expenses associated with its exercise of such rights, with no obligations of Company to

 6. Litigation and Other Proceedings. Upon the occurrence and during the continuation
of an Event of Default, the Escrow Agent shall have the right but not the obligation to bring suit or institute proceedings in the name of Company or the Class to enforce any rights in the Collateral, including any license thereunder, in which event
Company shall at the request of the Escrow Agent do any and all lawful acts and execute any and all documents reasonably required by the Escrow Agent in aid of such enforcement.

Agent at a place to be designated by the Escrow Agent; and (b) prior to the disposition of the Collateral, store, process, repair or recondition it or otherwise prepare it for disposition in any manner and to the extent the Escrow Agent deems
appropriate. Company hereby agrees that ten (10) days notice of any intended sale or disposition of any Collateral is reasonable.

incurred by the Escrow Agent that are required to be paid by Company pursuant to this Security Agreement or the Note; 
 (ii)
Second, to the payment to the Class of the amount then owing or unpaid on the Note on a pro rata basis, and in case such proceeds shall be insufficient to pay in full the whole amount so due, owing or unpaid upon such Note, then its pro rata
share of the amount remaining to be distributed (to be applied first to accrued interest and second to outstanding principal); 

(iii) Third, to the payment of other amounts then payable to the Class in accordance with the Transaction Documents, and in case
such proceeds shall be insufficient to pay in full the whole amount so due, owing or unpaid, then its pro rata share of the amount remaining to be distributed; and

 ATTACHMENT 1 
 TO SECURITY AGREEMENT 
 All right, title and interest of NWI in and to its
trade accounts receivable arising in the ordinary course of NWI’s business (collectively, the “Accounts Receivable”), provided that (a) as of any date of determination while this Security Agreement is in effect, the
aggregate value of the Collateral, as set forth in the quarterly report on Form 10-Q or annual report on Form 10-K then most recently filed by NWI with the SEC pursuant to the Securities Exchange Act, shall at all times be an amount equal to at
least the product determined by multiplying (i) five (5) by (ii) the outstanding amount of the Note as of any such date (including all outstanding principal and accrued interest) (the “Required Ratio”), and
(b) notwithstanding anything to the contrary in the Transaction Documents, (i) NWI is hereby permitted to sell, transfer or encumber at any time all or any portion of the Collateral not required to satisfy the Required Ratio, so long as
(A) both before and immediately after giving effect to any such sale, transfer or encumbrance, the Required Ratio is and will be satisfied, and (B) in the case of any such encumbrance, (1) if Company elects to encumber Collateral not
required to satisfy the Required Ratio and such Collateral is separate, identifiable and distinct from other existing Collateral (any such Collateral, “Separate Existing Collateral”), Company provides the Escrow Agent with a reasonably
detailed description of such Separate Existing Collateral to be so encumbered sufficient for filing with a UCC-3 amendment to the UCC-1 financing statement then covering the Collateral, to release the Escrow Agent’s security interests in such
Separate Existing Collateral and/or (2) if Company elects to encumber any existing or future Collateral not required to satisfy the Required Ratio and such Collateral is not Separate Existing Collateral (any such Collateral, “Other
Collateral”), Company causes the person or entity in favor of which any such encumbrance will be granted (each, an “Other Secured Party”) to enter into an agreement with the Escrow Agent, pursuant to which the Escrow Agent and the
Other Secured Party mutually agree upon an allocation of such Other Collateral between such parties, and the Escrow Agent hereby agrees to negotiate reasonably and in good faith in reaching such an agreement, and (ii) if Company sells,
transfers or encumbers Collateral having complied with and in accordance with the terms of subclause(b)(i) of this sentence, the Escrow Agent’s security interests and rights with respect to any such Collateral not required to satisfy the
Required Ratio shall be automatically released upon any such sale, transfer or encumbrance. Only those Accounts Receivable that have been outstanding for not more than ninety (90) calendar days from the original invoice date or date incurred if
no invoice shall be considered in computing NWI’s compliance with the Required Ratio.
