(ii) Each Grantor shall continue to collect, at its own expense, all amounts due or to become due to such Grantor under the Accounts. In connection with such collections, each Grantor may take (and, upon the occurrence and during the continuance of an Event of Default at Collateral Agent's direction, shall take) such action as such Grantor or Collateral Agent may deem necessary or advisable to enforce collection of amounts due or to become due under the Accounts; provided, however, that Collateral Agent shall have the right at any time, upon the occurrence and during the continuation of an Event of Default and upon written notice to such Grantor of its intention to do so, to (i) notify the account debtors or obligors under any Accounts of the assignment of such Accounts to Secured Party and to direct such account debtors or obligors to make payment of all amounts due or to become due to such Grantor thereunder directly to Collateral Agent, (ii) notify each Person maintaining a lockbox or similar arrangement to which account debtors or obligors under any Accounts have been directed to make payment to remit all amounts representing collections on checks and other payment items from time to time sent to or deposited in such lockbox or other arrangement directly to Collateral Agent, (iii) enforce collection of any such Accounts at the expense of Grantors, and (iv) adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Grantor might have done.

(b) The Collateral Agent may comply with any applicable law in connection with a disposition of Collateral and compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.
