Any surplus of such cash or cash proceeds held by the Administrative Agent and remaining after payment in full in cash of all the Secured Obligations shall be paid over to the applicable Grantor or to whomsoever may be lawfully entitled to receive such surplus.

SECTION VI.2. Indemnity and Expenses.

(a) The Grantor agrees to indemnify the Administrative Agent and the other Secured Parties from and against any and all claims, losses and liabilities arising out of or resulting from this Security Agreement (including enforcement of this Security Agreement), except claims, losses or liabilities resulting from the gross negligence or wilful misconduct of the Administrative Agent or the other Secured Parties.

(b) The Grantor will upon demand pay to the Administrative Agent and the other Secured Parties the amount of any and all reasonable expenses, including the reasonable fees and disbursements of its counsel and of any experts and agents, which the Administrative Agent may incur in connection with

(i) the administration of this Security Agreement,

(ii) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, any of the Collateral, and

(iii) the exercise or enforcement of any of the rights of the Administrative Agent or the Secured Parties hereunder, or

(iv) the failure by any Grantor to perform or observe any of the provisions hereof.
