(c) When Grantor or any of its Subsidiaries (or any affiliates, shareholders, directors, officers, employees, agents or those Persons acting for or in concert with Grantor or a Subsidiary of Grantor) shall receive or come into the possession or control of any monies, checks, notes, drafts or any other payment relating to, or proceeds of, Grantor's Accounts or other property constituting Collateral hereunder (individually, a "PAYMENT ITEM", and, collectively, "PAYMENT ITEMS"), then, except as otherwise permitted in a writing signed by the Secured Party, Grantor shall, or shall cause such Subsidiary or such other Person to, deposit the same in kind in precisely the form in which such Payment Item was received (with all Payment Items endorsed if necessary for collection) into an Account pledged by this Agreement.

(b) Grantor agrees that, from and after the occurrence of an Event of Default, Secured Party may, but need not, make any payment or perform any act hereinbefore required of Grantor with respect to the Grantor's leased premises in any form and manner deemed expedient.

Section 17. REMEDIES. If any Event of Default shall have occurred and be continuing:

(a)(i) Secured Party shall have, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC (whether or not the UCC applies to the affected Collateral) and further, Secured Party may, without notice, demand or legal process of any kind (except as may be required by law), all of which Grantor waives, at any time or times, (x) enter Grantor's owned or leased premises and take physical possession of the Collateral and maintain such possession on Grantor's owned or leased premises, at no cost to Secured Party, or remove the Collateral, or any part thereof, to such other place(s) as Secured Party may desire, (y) require Grantor to, and Grantor hereby agrees that it will at its expense and upon request of Secured Party forthwith, assemble all or any part of the Collateral as directed by Secured Party and make it available to Secured Party at a place to be designated by Secured Party which is reasonably convenient to Secured Party and (z) without notice except as specified below, sell, lease, assign, grant an option or options to purchase or otherwise dispose of the Collateral or any part thereof at public or private sale, at any exchange, broker's board or at any of the offices of Secured Party or elsewhere, for cash, on credit or for future delivery, and upon such other terms as Secured Party may deem commercially reasonable. Grantor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days' notice to Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification and that Secured Party may purchase all or any portion of the Collateral at such sale. Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned;

(ii) Secured Party shall apply all cash proceeds received by Secured Party in respect of any sale of, collection from, or other realization upon all or any part of the Collateral (after payment of any amounts payable to Secured Party pursuant to SECTION 22), against all or any part of the Obligations in such order as may be required by the Note or, to the extent not specified therein, as is determined by the Secured Party. Any surplus of such cash or cash proceeds held by Secured Party and remaining after payment in full of all the Obligations shall be paid over to Grantor or to whomsoever may be lawfully entitled to receive such surplus;

(b) Grantor waives all claims, damages and demands against Secured Party arising out of the repossession, retention or sale of any of the Collateral or any part or parts thereof, except any such

claims, damages and awards arising out of the gross negligence or willful misconduct of Secured Party, as determined in a final non-appealed judgment of a court of competent jurisdiction; and

(c) The rights and remedies provided under this Agreement are cumulative and may be exercised singly or concurrently and are not exclusive of any rights and remedies provided by law or equity.

Section 18. EXERCISE OF REMEDIES. In connection with the exercise of its remedies pursuant to SECTION 17, Secured Party may, (a) exchange, enforce, waive or release any portion of the Collateral and any other security for the Obligations; (b) apply such Collateral or security and direct the order or manner of sale thereof as Secured Party may, from time to time, determine; and (c) settle, compromise, collect or otherwise liquidate any such Collateral or security in any manner following the occurrence of an Event of Default, without affecting or impairing Secured Party's right to take any other further action with respect to any Collateral or security or any part thereof.

Section 19. LICENSE. Secured Party is hereby granted a license or other right to use, following the occurrence and during the continuance of an Event of Default, without charge, (a) Grantor's labels, patents, copyrights, trade secrets, trade names, trademarks, service marks, customer lists and advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral, provided that Secured Party uses quality standards at least substantially equivalent to those of Grantor for the manufacture, advertising, sale and distribution of Grantor's products and services and (b) Grantor's rights under all licenses and all franchise agreements shall inure to Secured Party's benefit.

Section 20. INJUNCTIVE RELIEF. Grantor recognizes that in the event Grantor fails to perform, observe or discharge any of its obligations or liabilities under this Agreement, any remedy of law may prove to be inadequate relief to the Secured Party; therefore, Grantor agrees that the Secured Party, if Secured Party so determines and requests, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages.

Section 21. INTERPRETATION AND INCONSISTENCIES; MERGER.

(a) The rights and duties created by this Agreement shall, in all cases, be interpreted consistently with, and shall be in addition to (and not in lieu of), the rights and duties created by the Note. In the event that any provision of this Agreement shall be inconsistent with any provision of the Note, such provision of the Note shall govern.

(b) Except as provided in subsection (a) above, this Agreement represents the final agreement of the Grantor and the Secured Party with respect to the matters contained herein and may not be contradicted by evidence of prior or contemporaneous agreements, or subsequent oral agreements, between the Grantor and the Secured Party.

Section 22. EXPENSES. Grantor will upon demand pay to Secured Party the amount of any and all reasonable expenses, including the reasonable fees and disbursements of its counsel and of any experts and agents.

Section 23. AMENDMENTS, ETC. No amendment or waiver of any provision of this Agreement nor consent to any departure by Grantor herefrom shall in any event be effective unless the same shall be in writing and signed by Secured Party and Grantor, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

Section 24. NOTICES. All notices and other communications provided for hereunder shall be delivered in the manner set forth in of the Note.

Section 25. CONTINUING SECURITY INTEREST; TERMINATION.

(a) Except as provided in SECTION 25(b), this Agreement shall create a continuing security interest in the Collateral and shall (i) remain in full force and effect until the later of the payment or

satisfaction in full of the Obligations (other than contingent indemnity obligations) and the payment in full of the Note, (ii) be binding upon Grantor, its successors and assigns and (iii) except to the extent that the rights of any transferor or assignor are limited by the terms of the Note, inure, together with the rights and remedies of Secured Party hereunder, to the benefit of Secured Party. Nothing set forth herein or in the Note is intended or shall be construed to give any other Person any right, remedy or claim under, to or in respect of this Agreement or the Note or any Collateral. Grantor's successors and assigns shall include, without limitation, a receiver, trustee or debtor-in-possession thereof or therefor.

(b) Upon the payment in full in cash of the Obligations (other than contingent indemnity obligations) and the payment in full of the Note, this Agreement and the security interest granted hereby shall terminate and all rights to the Collateral shall revert to Grantor. Upon any such termination of security interest, Grantor shall be entitled to the return, upon its request and at its expense, of such of the Collateral held by Secured Party as shall not have been sold or otherwise applied pursuant to the terms hereof and Secured Party will, at Grantor's expense, execute and deliver to Grantor such other documents as Grantor shall reasonably request to evidence such termination. In connection with any sales of assets permitted under the Note, the Secured Party will release and terminate the liens and security interests granted under this Agreement with respect to such assets.

Section 26. SEVERABILITY; NO STRICT CONSTRUCTION. (a) It is the parties' intention that this Agreement be interpreted in such a way that it is valid and effective under applicable law. However, if one or more of the provisions of this Agreement shall for any reason be found to be invalid or unenforceable, the remaining provisions of this Agreement shall be unimpaired.

(b) The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.
