Each Grantor hereby irrevocably appoints the Agent as such Grantor's attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time in the Agent's discretion, to take any action and to execute any instrument which the Agent may deem necessary or advisable to accomplish the purposes of this Security Agreement, including, without limitation: (a) to ask, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral; 15 (b) to receive, endorse, and collect any drafts or other instruments, documents and chattel paper, in connection with CLAUSE (A above; (c) to file any claims or take any action or institute any proceedings which the Agent may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Agent with respect to any of the Collateral; and (d) to perform the affirmative obligations of such Grantor hereunder (including all obligations of such Grantor pursuant to SECTION 4.1.7). Each Grantor hereby acknowledges, consents and agrees that the power of attorney granted pursuant to this Section is irrevocable and coupled with an interest. SECTION 5.2. AGENT MAY PERFORM. If any of the Grantors fail to perform any agreement contained herein, the Agent may itself perform, or cause performance of, such agreement, and the expenses of the Agent incurred in connection therewith shall be payable by the applicable Grantor pursuant to SECTION 6.2. SECTION 5.3. AGENT HAS NO DUTY. In addition to, and not in limitation of, SECTION 2.4, the powers conferred on the Agent hereunder are solely to protect its interest (on behalf of the Lender Parties) in the Collateral and shall not impose any duty on it to exercise any such powers.

SECTION 5.4. REASONABLE CARE. The Agent is required to exercise reasonable care in the custody and preservation of any of the Collateral in its possession; PROVIDED, HOWEVER, the Agent shall be deemed to have exercised reasonable care in the custody and preservation of any of the Collateral, if it takes such action for that purpose as any of the Grantors reasonably request in writing at times other than upon the occurrence and during the continuance of any Event of Default, but failure of the Agent to comply with any such request at any time shall not in itself be deemed a failure to exercise reasonable care. ARTICLE VI REMEDIES SECTION 6.1. CERTAIN REMEDIES. (a) If any Event of Default shall have occurred and be continuing: (i) The Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the UCC (whether or not the UCC applies to the affected Collateral) and also may (A) require the Grantors to, and the Grantors hereby agrees that it will, at its expense and upon request of the Agent forthwith, assemble all 16 or part of the Collateral as directed by the Agent and make it available to the Agent at a place to be designated by the Agent which is reasonably convenient to both parties and (B) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Agent's offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Agent may deem commercially reasonable. The Grantors agrees that, to the extent notice of sale shall be required by law, at least ten days' prior notice to the Grantors 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. The Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Agent 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) All cash proceeds received by the Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Agent, be held by the Agent as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Agent pursuant to SECTION 6.2) in whole or in part by the Agent for the ratable benefit of the Lender Parties against, all or any part of the Obligations in such order as the Agent shall elect. Any surplus of such cash or cash proceeds held by the Agent and remaining after final payment in full of all the Obligations shall be paid over to the Grantors or to whomsoever may be lawfully entitled to receive such surplus. (b) In furtherance of, and not in limitation of, the foregoing, the Agent, without demand of performance or other demand, advertisements or notice of any kind (except the notice specified below of time and place of public or private sale) to or upon the Grantors or any other Person (all and each of which demands, advertisements and/or notices are hereby expressly waived), may, whenever an Event of Default shall have occurred and be continuing, in a commercially reasonable manner, forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, assign, give option or options to purchase, contract to sell or otherwise dispose of and deliver said Collateral, or any part thereof, in one or more parcels at public or private sale or sales, at any exchange, broker's board or at any of the Agent's offices or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk, with the right to the Agent upon any such sale or sales, public or private, to purchase the whole or any part of said Collateral so sold, free of any right or equity of redemption in the Grantors, which right or equity is hereby expressly waived or released. The Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care, safekeeping or otherwise of any and 17 all of the Collateral or in any way relating to the rights of the Agent hereunder, including reasonable attorneys' fees and legal expenses, to the payment in whole or in part of the Obligations in such order as the Agent may elect, the Grantors remaining liable for any deficiency remaining unpaid after such application and all fees and expenses incurred by the Agent in collecting such deficiency, and only after so paying over such net proceeds and after the payment by the Agent of any other amount required by any provision of law, including, without limitation, Section 9-615 of the UCC, need the Agent account for the surplus, if any, to the Grantors. Unless the Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, in which event no notification is required, the Grantors agree that the Agent need not give more than ten days' notice of the time and place of any public sale or of the time after which a private sale or other intended disposition is to take place and that such notice is reasonable notification of such matters. No notification need be given to any Grantors if such Grantor has signed after default a statement renouncing or modifying any right to notification of sale or other intended disposition. The Grantors further agree to waive and agree not to assert any rights or privileges which they may acquire under Section 9-615 of the UCC. For the purpose of enabling the Agent to exercise rights and remedies under this Agreement and the Security Agreement Supplement, at such time as the Agent shall be lawfully entitled to exercise such rights and remedies, and for no other purpose, but as a supplement to and not in limitation of any and all other rights and remedies available to the Agent and to the extent the Agent chooses to avail itself of the following, the grants, to the extent not prohibited by applicable law or existing licenses granted in the ordinary course of business (unless and until appropriate consents have been obtained), to the Agent an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to the Borrower), which license shall be exercisable by the Agent upon and subject to the occurrence and during the continuance of an Event of Default, to use, license or sublicense and to enhance, alter or otherwise modify any Patent Collateral, Copyright Collateral and, subject the maintenance of quality standards comparable to those heretofore maintained by each Grantor in connection with the same or similar goods and services, Trademark Collateral, now owned or hereafter acquired by such Grantor (including, in the case of a license with respect to Copyright Collateral, reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer hardware used for the compilation, storage or printout thereof); PROVIDED, HOWEVER, that (i) to the extent such Patent Collateral consists of patent licenses or other agreements that provide such Grantor with the right to use patented technology, the non-exclusive license granted hereby to the Agent shall be subject to the terms and conditions contained in such patent licenses or such other agreements, including without limitation restrictions on the right to sub-license, (ii) to the extent such Copyright Collateral consists of copyright and/or mask work licenses or other agreements that provide such Grantor with the right to use any of the types of items referred to in CLAUSE (I) of the definition of "Copyright Collateral", the non-exclusive license granted hereby to the Agent shall be subject to the terms and conditions contained in such copyright and/or mask work licenses or such other agreements, including without limitation restrictions on the right to sub-license, as the case may be, and (iii) to the extent such Trademark Collateral consists of trademark licenses or other agreements that provide such Grantor with the right to use any of the types of items referred to in CLAUSE (I) of the definition of "Trademark Collateral", the non-exclusive license granted hereby to the Agent shall be subject to the terms and conditions 18 contained in such trademark license or other agreements, including without limitation, restrictions on the right to sub-license, as the case may be.
