The Grantor hereby agrees that it shall supplement the Schedules hereto promptly upon obtaining information which would require any material correction or addition to the information therein which would require any action in order to perfect or maintain the perfection of the Secured Party’s security interest in the Collateral and shall promptly deliver such updated Schedules to the Secured Party.

The Grantor hereby appoints the Secured Party the Grantor's attorney-in-fact, with full authority in the place and stead of the Grantor and in the name of the Grantor or otherwise, from time to time during the continuance of an Event of Default in the Secured Party's discretion to take any action and to execute any instrument which the Secured Party may deem necessary or advisable to accomplish the purposes of this Agreement (but the Secured Party shall not be obligated to and shall have no liability to the Grantor or any third party for failure to do so or take action). This appointment, being coupled with an interest, shall be irrevocable. The Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof.

9. Secured Party May Perform. If the Grantor fails to perform any obligation contained in this Agreement, the Secured Party may itself perform, or cause performance of, such obligation, and the expenses of the Secured Party incurred in connection therewith shall be payable by the Grantor; provided that the Secured Party shall not be required to perform or discharge any obligation of the Grantor.

10. Reasonable Care. The Secured Party shall have no duty with respect to the care and preservation of the Collateral beyond the exercise of reasonable care. The Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Secured Party accords its own property, it being understood that the Secured Party shall not have any responsibility for (a) ascertaining or taking action with respect to any claims, the nature or sufficiency of any payment or performance by any party under or pursuant to any agreement relating to the Collateral or other matters relative to any Collateral, whether or not the Secured Party has or is deemed to have knowledge of such matters, or (b) taking any necessary steps to preserve rights against any parties with respect to any Collateral. Nothing set forth in this Agreement, nor the exercise by the Secured Party of any of the rights and remedies hereunder, shall relieve the Grantor from the performance of any obligation on the Grantor's part to be performed or observed in respect of any of the Collateral.

11. Remedies Upon Default.

(a) If any Event of Default shall have occurred and be continuing, the Secured Party, without any other notice to or demand upon the Grantor, may assert all rights and remedies of a secured party under the UCC or other applicable law, including, without limitation, the right to take possession of, hold, collect, sell, lease, deliver, grant options to purchase or otherwise retain, liquidate or dispose of all or any portion of the Collateral. If notice prior to disposition of the Collateral or any portion thereof is necessary under applicable law, written notice mailed to the Grantor at its notice address as provided in Section 15 hereof ten days prior to the date of such disposition shall constitute reasonable notice, but notice given in any other reasonable manner shall be sufficient. So long as the sale of the Collateral is made in a commercially reasonable manner, the Secured Party may sell such Collateral on such terms and to such purchaser(s) as the Secured Party in its absolute discretion may choose, without assuming any credit risk and without any obligation to advertise or give notice of any kind other than that necessary under applicable law. Without precluding any other methods of sale, the sale of the Collateral or any portion thereof shall have been made in a commercially reasonable manner if conducted in conformity with reasonable commercial practices of creditors disposing of similar property. At any sale of the Collateral, if permitted by applicable law, the Secured Party may be the purchaser, licensee, assignee or recipient of the Collateral or any part thereof and shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold, assigned or licensed at such sale, to use and apply any of the Secured Obligations as a credit on account of the purchase price of the Collateral or any part thereof payable at such sale. To the extent permitted by applicable law, the Grantor waives all claims, damages and demands it may acquire against the Secured Party arising out of the exercise by it of any rights hereunder. The Grantor hereby waives and releases to the fullest extent permitted by law any right or equity of redemption with respect to the Collateral, whether before or after sale hereunder, and all rights, if any, of marshalling the Collateral and any other security for the Secured Obligations or otherwise. At any such sale, unless prohibited by applicable law, the Secured Party or any custodian may bid for and purchase all or any part of the Collateral so sold free from any such right or equity of redemption. Neither the Secured Party nor any custodian shall be liable for failure to collect or realize upon any or all of the Collateral or for any delay in so doing, nor shall it be under any obligation to take any action whatsoever with regard thereto. The Grantor agrees that it would not be commercially unreasonable for the Secured Party to dispose of the Collateral or any portion thereof by utilizing internet sites that provide for the auction of assets of the type included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets. The Secured Party shall not be obligated to clean-up or otherwise prepare the Collateral for sale.

(b) If any Event of Default shall have occurred and be continuing, all rights of the Grantor to (i) exercise the voting and other consensual rights it would otherwise be entitled to exercise pursuant to Section 6(a) and (ii) receive the dividends and other distributions which it would otherwise be entitled to receive and retain pursuant to Section 6(b), shall immediately cease, and all such rights shall thereupon become vested in the Secured Party, which shall have the sole right to exercise such voting and other consensual rights and receive and hold such dividends and other distributions as Collateral.

(c) If any Event of Default shall have occurred and be continuing, any cash held by the Secured Party as Collateral and all cash Proceeds received by the Secured Party in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied in whole or in part by the Secured Party to the payment of expenses incurred by the Secured Party in connection with the foregoing or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Secured Party hereunder, including reasonable attorneys' fees, and the balance of such proceeds shall be applied or set off against the Secured Obligations.

(d) Any surplus of such cash or cash Proceeds held by the Secured Party and remaining after payment in full of all the Secured Obligations shall be paid over to the Grantor or to whomsoever may be lawfully entitled to receive such surplus. The Grantor shall remain liable for any deficiency if such cash and the cash Proceeds of any sale or other realization of the Collateral are insufficient to pay the Secured Obligations and the reasonable fees and other charges of any attorneys employed by the Secured Party to collect such deficiency.

(e) If the Secured Party shall determine to exercise its rights to sell all or any of the Collateral pursuant to this Section, the Grantor agrees that, upon request of the Secured Party, the Grantor will, at its own expense, do or cause to be done all such acts and things as may be necessary to make such sale of the Collateral or any part thereof valid and binding and in compliance with applicable law.

12. No Waiver and Cumulative Remedies. The Secured Party shall not by any act (except by a written instrument pursuant to Section 14), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. All rights and remedies herein provided are cumulative and are not exclusive of any rights or remedies provided by law.

13. SECURITY INTEREST ABSOLUTE. The Grantor hereby waives, to the extent permitted by Law, demand, notice, protest, notice of acceptance of this Agreement, notice of loans made, credit extended, Collateral received or delivered or other action taken in reliance hereon and all other demands and notices of any description. All rights of the Secured Party and liens and security interests hereunder, and all Secured Obligations of the Grantor hereunder, shall be absolute and unconditional irrespective of:

(a) Any illegality or lack of validity or enforceability of any Secured Obligation or any related agreement or instrument;

(b) any change in the time, place or manner of payment of, or in any other term of, the Secured Obligations, or any rescission, waiver, amendment or other modification of the Purchase Agreement, this Agreement or any other agreement, including any increase in the Secured Obligations resulting from any extension of additional credit or otherwise;

(c) any taking, exchange, substitution, release, impairment or non-perfection of any Collateral or any other collateral, or any taking, release, impairment, amendment, waiver or other modification of any guaranty, for all or any of the Secured Obligations;

(d) any manner of sale, disposition or application of proceeds of any Collateral or any other collateral or other assets to all or part of the Secured Obligations;

(e) any default, failure or delay, willful or otherwise, in the performance of the Secured Obligations;

(f) any defense, set-off or counterclaim (other than a defense of payment or performance) that may at any time be available to, or be asserted by, the Grantor against the Secured Party; or

(g) any other circumstance (including, without limitation, any statute of limitations) or manner of administering the Note or any existence of or reliance on any representation by the Secured Party that might vary the risk of the Grantor or otherwise operate as a defense available to, or a legal or equitable discharge of, the Grantor or any other grantor, guarantor or surety.

14. Amendments. None of the terms or provisions of this Agreement may be amended, modified, supplemented, terminated or waived, and no consent to any departure by the Grantor therefrom shall be effective unless the same shall be in writing and signed by the Secured Party and the Grantor, and then such amendment, modification, supplement, waiver or consent shall be effective only in the specific instance and for the specific purpose for which made or given.

15. Addresses For Notices. All notices and other communications provided for in this Agreement shall be in writing and shall be given in the manner and become effective as set forth in the Purchase Agreement, and addressed to the respective parties at their addresses as specified in Section 9(h) of the Purchase Agreement or as to either party at such other address as shall be designated by such party in a written notice to each other party.

16. Continuing Security Interest; Further Actions. This Agreement shall create a continuing First Priority lien and security interest in the Collateral and shall (a) subject to Section 17, remain in full force and effect until payment and performance in full of the Secured Obligations, (b) be binding upon the Grantor, its successors and assigns, and (c) inure to the benefit of the Secured Party and its successors, transferees and assigns; provided that the Grantor may not assign or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of the Secured Party.

17. Termination; Release. On the date on which all Secured Obligations have been paid and performed in full, the Secured Party will, at the request and sole expense of the Grantor, (a) duly assign, transfer and deliver to or at the direction of the Grantor (without recourse and without any representation or warranty) such of the Collateral as may then remain in the possession of the Secured Party, together with any monies at the time held by the Secured Party hereunder, and (b) execute and deliver to the Grantor a proper instrument or instruments acknowledging the satisfaction and termination of this Agreement.
